PHOTO: A chiseled, statuesque man wearing the COOLEST SUPER HERO SUIT IMAGINABLE, COMPLETE WITH FLOWING CAPE, shines a confident smile at the lens. This is UBERMAN, champion of METRO CITY. "UBERMAN DEFEATS MASTER MIND'S GIANT ROBOT!" PHOTO: Wide-shot of Uberman in mid-flight lifting the GIANT ROBOT in the sky above the city buildings. "MASTER MIND ALL WET AFTER UBERMAN FOILS AQUARIUM HEIST!" PHOTO: Uberman stands knee-deep in water. He has his enemy by the collar. The villain blocks his face from the shot with a METALLIC GAUNTLET. The images start to flash by even quicker, each showing the MYSTERIOUS VILLAIN in various stages of humiliation. In each photograph he successfully blocks his face with his armored glove. We ZOOM IN to the last headline. "MASTER MIND BEHIND BARS ONCE AGAIN - THANKS TO UBERMAN!" PHOTO: Uberman stands in a gallant pose with his fists on his hips, obviously trying to accentuate the "U" insignia on his chest. END OF CREDITS SEQUENCE EXT. BUILDING - DAY We DISSOLVE from the photograph to Uberman standing in the exact same position. WE PULL BACK showing him atop a BUILDING overlooking the city below. A perfect view for our guardian hero. He watches the thriving metropolis, bristling with life as people happily go about their day. Yet, we can't help but detect a hint of sadness in Uberman's expression. 2. UBERMAN You look so peaceful from up here. His serenity is suddenly interrupted by a loud BEEPING SOUND coming from his wrist. He looks down at a BRACELET (a manly one) on his right arm. It's a silver band with a FLASHING red letter "U". UBERMAN (CONT'D) Looks like Roxanne's in trouble again. Uberman leaps off the building and into the air. His cape gracefully flows in the breeze behind him as he shoots off into the distance like a speeding bullet. EXT. OBSERVATORY HIDEOUT - ESTABLISHING SHOT Grime and moss decorate the outside of this long abandoned building overlooking the COAST. Once a place of knowledge and wonder - now home to a great evil. INT. OBSERVATORY HIDEOUT - DAY The inside is in complete contrast to the exterior. The huge hall with a GIANT TELESCOPE teems with advanced ELECTRONIC EQUIPMENT. Computers, monitors and machines which do not have an obvious function FLASH and HUM. A STEEL DOOR slides open, revealing the subject of our story MASTER MIND - a villainous sight to behold. His FACE IS INEXPLICABLY LIGHT BLUE, topped by an OVERSIZED, MUSHROOM- SHAPED HEAD with a CIRCULAR PATCH OF WHITE HAIR ON TOP. He's dressed in the kind of costume only a super villain could pull off: a PURPLE JUMPSUIT AND BLACK BOOT ENSEMBLE WITH A GIANT GREEN "M" ON THE CHEST. His right hand, hanging at his side, is a METAL GAUNTLET WITH THREE SHORT SPIKES PROTRUDING BETWEEN HIS KNUCKLES. Master Mind begins to survey the room with his TWO PERMANENTLY ARCHED EYEBROWS. A man dressed as ALBERT EINSTEIN is busy ranting to two other men. One, a hulking brute, is dressed as LEONARDO DA VINCI. The other, a small intellectual-type carrying a clip-board, is dressed as the philosopher PLATO. EINSTEIN I hate the outfits. I mean, I get it: we're all supposed to be "masterminds" - very clever. (MORE) 3. EINSTEIN(cont'd) I just feel stupid. I mean, what the hell did Einstein really do anyway? PLATO Theory of relativity. Einstein starts feverishly scratching his side. EINSTEIN Well, you'd think he'd invent a wool sweater that didn't itch so much. Da Vinci and Plato's eyes suddenly grow with concern as they see Master Mind walk up behind Einstein. Einstein notices his colleague's staring over his right shoulder and turns around. He turns around and Master Mind SEIZES HIM BY HIS THROAT with his metal gauntlet. MASTER MIND The real Einstein once said, "God does not play dice with the world." He was right, because the world is MY dice. Is that understood? DA VINCI & PLATO Sir! Yes, sir! EINSTEIN (gasping for air) Yes, sir. Master Mind undoes his grip on Einstein's throat. MASTER MIND Alright, then - clean slate. Do we have the girl? DA VINCI Yes, sir. She fell into our trap just like you knew she would. MASTER MIND Reporters are a curious lot, and easily manipulated. He quickly checks his physique in a GIANT MIRROR, adjusts his posture and sucks in his gut. 4. MASTER MIND Alright, let's not keep the lady waiting. MOMENTS LATER Da Vinci escorts a BLINDFOLDED and bound woman, ROXANNE RITCHI, to the back of the room where Plato and Einstein are standing guard over a large BLACK SWIVEL-CHAIR facing away from us. She pulls free of Da Vinci's grasp and waits for him to undo the blindfold. Her face uncovered, we finally see Roxanne's striking features - all of which seem overshadowed by piercing eyes that seem more put off by the situation than afraid of it. MASTER MIND (O.S.) Miss Ritchi, we meet again. The chair turns menacingly slow, finally revealing Master Mind. ROXANNE You didn't need to turn around like that. I can recognize the stench of failure. Master Mind unleashes a wicked laugh. MASTER MIND I trust you gentlemen know the very sassy Roxanne Ritchi, highly regarded investigative journalist who some say has a more than friendly relationship with our super powered foe Uberman. And Miss Ritchi, I trust you've already met my new crew: The Mad Geniuses! Roxanne gives Einstein a once over. ROXANNE Looks like a real group of winners. At the risk of sounding cliche', you'll never get away with this. MASTER MIND In a way, I already have. Roxanne unleashes an exhausted SIGH. 5. ROXANNE We go through this every time. You kidnap me to get to Uberman, he immediately finds your hideout, escapes whatever lame trap you've come up with, and takes you and your cronies to jail. I propose we just save everybody some heartache this time by YOU letting me go, and ME forgetting this whole thing ever happened? MASTER MIND What about my revenge? ROXANNE We can say it was wasting everyone's time. MASTER MIND You have a wicked tongue. I hope you rid yourself of that when you're my queen. Roxanne unleashes a snort-filled laugh. ROXANNE I'm sorry. What makes you think I would want to be your queen? MASTER MIND Power corrupts absolutely, Miss Ritchi. And when I have ultimate power over this city, I have absolutely every intention of corrupting you with it. PLATO Sir! Master Mind turns to Plato who's now standing at a computer terminal. MASTER MIND (annoyed) What is it!? EXT. OBSERVATORY HIDEOUT - DAY Uberman flies toward the Observatory like a rocket. 6. INT. OBSERVATORY HIDEOUT - DAY Uberman crashes through the wall to the room we were just in. He looks around, but there's suddenly NOT A SOUL IN SIGHT. CUT TO: EXT. MASTER MIND'S HYDROFOIL - DAY The boat is shooting through the ocean, away from the observatory. INT. HYDROFOIL CONTROL ROOM - DAY Machines, cables and terminals criss-cross the craft's main bridge. Through the enormous surrounding windows we can see the observatory shrinking in the distance. Master Mind watches Uberman on a small TV monitor as the hero intently searches his hideout. UBERMAN (on monitor) Master Mind! INT. OBSERVATORY HIDEOUT - DAY Uberman throws up his arms in frustration when suddenly - MASTER MIND (O.S.) Over here, old friend. He turns to see a FAMILIAR BLUE FACE OF EVIL ON A GIANT SCREEN. UBERMAN What's the matter, miss your old jail cell? Uberman starts walking toward the monitor. MASTER MIND (ON MONITOR) Actually, I wanted to share the experience with my oldest friend. A MECHANIZED CAGE shoots out of the floor, suddenly trapping Metro City's protector. Totally unfazed, our hero stares on. 7. UBERMAN You can't possibly believe this will work. Master Mind pulls out a SMALL BLACK BOX with a SINGLE RED BUTTON on it. MASTER MIND (ON MONITOR) Oh, can't I? I have attained control of the Earth's most abundant energy source. I doubt even you are strong enough to withstand the FULL CONCENTRATED POWER OF THE SUN!!! He presses the button. EXT. OUTER SPACE A sinister-looking SATELLITE orbits Earth's atmosphere. Its bay doors suddenly open, deploying two huge SOLAR PANELS. The panels shift, angling themselves in the direction of the sun. They immediately start GLOWING as they absorb the burning star's power. The front of the satellite begins to make a loud HUMMING SOUND as it prepares to unleash its unholy power. INT. HYDROFOIL CONTROL ROOM - DAY From the giant window we can see the boat is a good mile from the observatory. PLATO We're now at minimum safe distance, master. Master Mind turns from the CAMERA he was broadcasting on and puts down the control box. MASTER MIND Excellent. Stop here, I like this view. PLATO Twenty seconds until impact. Master Mind turns to Roxanne who is being held by Da Vinci and Einstein. She almost appears a little bored. Disappointed by her lack of horror, he walks over to the monitor now showing Uberman trapped in the cage. 8. MASTER MIND Any last words? Uberman looks up at the screen with a cocky smile. UBERMAN (ON MONITOR) Yes: there's no caging the power of justice. PLATO Ten seconds to impact. On the screen we see Uberman take two of the cage's bars in his hands. He yanks...NOTHING. PLATO (CONT'D) Nine... Master Mind stares at the monitor, slightly confused. PLATO (CONT'D) Eight... Uberman yanks on the bars again, this time using his foot as leverage. MASTER MIND (genuinely concerned) What's going on? UBERMAN (straining) Hold...on...a second. Master Mind looks back at Plato and Einstein. They're equally befuddled at the hero's sudden weakness. PLATO Seven... Uberman loses his grip and FALLS BACKWARD ON HIS ASS. UBERMAN SON OF A BITCH!! Master Mind and the minions all cringe in unison. Da Vinci turns to Roxanne not believing his ears. DA VINCI What did he just say? 9. PLATO Six......Five... Master Mind begins to laugh. MASTER MIND What kind of trick is this? Uberman looks up at the camera with a very grave expression. UBERMAN Like you don't know. These bars are made of copper, aren't they? PLATO Four... MASTER MIND Yeah, so? Uberman tries to shield his grief with his hand. UBERMAN You figured out my weakness, damn you. I CAN'T BEND COPPER! PLATO Three... MASTER MIND Your weakness is copper? PLATO Two...one. Everyone turns to the window. EXT. OUTER SPACE The satellite fires a giant BEAM OF LIGHT toward the earth. EXT. OBSERVATORY HIDEOUT - DAY The beam hits the observatory. The building instantly EXPLODES in a white nova blast of fire. INT. HYDROFOIL CONTROL ROOM - DAY The blast is so bright everyone turns away from the window. Then, as suddenly as it began, the awesome light dies out. One by one, the passengers unshield their eyes and look out toward the observatory. 10. All we can see through the haze of destruction is fire and smoke. PLATO I don't think even he could have survived that. Einstein suddenly turns giddy with excitement. EINSTEIN Whoa! Is it me or did you just finally destroy Uberman? MASTER MIND (carefully skeptical) Well...let's not get ahead of ourselves. Da Vinci suddenly sees something outside. DA VINCI Look, there's something in the sky, coming this way. ROXANNE Uberman! Master Mind turns toward the window. An object is in the air, flying directly toward them. As it closes in we can just make out the FAMILIAR OUTLINE OF A CAPPED FIGURE. MASTER MIND I KNEW IT! PREPARE YOURSELVES! HE'S GONNA RAM US!!! Everyone scatters and braces themselves for the impact. Master Mind, seeing all the good places taken, doesn't know what to do with himself. He just covers his giant head with his hands. The figure CRASHES THROUGH THE WINDOW and lands at his feet. He looks down to see a CHARRED BLACK HUMAN SKELETON. Around its neck is the unmistakable black cape of Uberman. MASTER MIND (CONT'D) (horrified) HOLY SHIT! 11. Roxanne breaks out of Da Vinci's hold and runs over to the body. ROXANNE Uberman? She stares down at the still smoking corpse, the tattered black cape with the yellow "U" on it. Roxanne turns to Master Mind, who's still visibly dumbfounded at the grotesque sight before him. ROXANNE (CONT'D) You killed him! Roxanne's eyes roll back. Da Vinci catches her from behind as she FAINTS. Einstein turns to Master Mind, looking at him as if he's just walked on water. EINSTEIN You did it! Now that he's committed the impossible - our villain is at a complete loss. MASTER MIND ...so I did. EINSTEIN I mean, I know you always wanted to. I mean, all the schemes all the plots - I never thought you'd actually be capable of it. Giddy as a school girl, Einstein turns to his fellow henchmen. EINSTEIN This is history. Every villain and lackey in the history of villains and lackeys dream of this moment, but when does it actually EVER happen? A sudden realization comes over his face. EINSTEIN Good lord...You do all realize what we get to do now, don't you? 12. His question is met with acquisitive looks from Master Mind and the others. EINSTEIN We get to go on a crime wave. CRIME WAVE MONTAGE - SET TO "Fun Fun Fun" by The Beach Boys. SPINNING HEADLINE: "UBERMAN'S DEATH IGNITES CITY WIDE CRIME WAVE!" ARMORED TRUCK It's driving along when the men inside suddenly notice something - THEY'RE FLYING HIGH ABOVE THE CITY STREETS. We PULL BACK to see the truck being carried by a giant claw at the bottom of a BRAIN COPTER. Inside the cockpit Master Mind and his henchmen laugh maniacally. SPINNING HEADLINE: "CHAMPION-LESS CITY AT THE MERCY OF HOOLIGANS." METRO CITY BANK Da Vinci and Einstein run out the front of the bank holding BAGS OF MONEY. Two beat officers see them and take chase after them around the corner and into an alley. After a moment the police reemerge from the alley screaming and running for their lives as a GIANT ROBOT CHASES after them. The robot stops, then suddenly it's head opens up like convertible car top with Master Mind and Plato at the driver's wheel. They smile and shake hands at a bad deed well done. SPINNING HEADLINE: "MASTER MIND BLACKMAILS METRO!!!" A VICIOUS TORNADO It's heading for downtown Metro as Master Mind and the lackeys coolly look on. Three large DUMP TRUCKS pull up, filled to the brim with bricks of CASH. 13. The DRIVERS jump out as the lackeys take the driver seats in the three trucks. Master Mind is about to climb into the passenger seat of one when a drivers taps him on the shoulder and motions toward the tornado. MASTER MIND (absentmindedly) Oh, right. Master Mind pulls a television REMOTE from his pocket and aims it at approaching windstorm of death. He presses the button marked "Tornado Off." The tornado shrinks and disappears just before it hits the city. As they drive through the city streets, Master stares out the window with a hint of something in his eyes. Is it melancholy? END OF MONTAGE EXT. KINGPIN BOWLING - DAY It's Metro City's premier bowling alley. On top of the neon lit building is a GIANT 30 FOOT TALL CEMENT BOWLING BALL. INT. KINGPIN BOWLING - DAY HAL STEWART (early 30's) takes careful aim with his BOWLING BALL. HAL It's a sport of honor, focus and grace. Honor the ball, focus on the pins, release the ball not hard and fast, but as if you were releasing a baby dove. He takes a step, pulls back his arm, and releases the ball, following it with his eyes. It's a horrible shot - INSTANT GUTTER BALL. An aged barmaid type with a cigarette hanging from her mouth looks over at him. HAL Okay, do something like that - but center it more. 14. She picks up her custom made FOGHAT BALL and takes aim. ATTRACTIVE BLOND Tell me how my form looks, honey. Hal focuses on the misshapen bumps of her enormous Johnson administration era derriere. HAL Oh, it's lookin' good. It's lookin' REAL good. It doesn't get anymore clear. This man is a pig. VINNIE (O.S.) Hal, I want to see you in my office! Hal turns to see VINNIE, owner of the bowling alley, calling him. VINNIE Now! INT. KINGPIN BOWLING - VINNIE'S OFFICE - MOMENTS LATER Hal sits down, facing Vinnie who's sitting at his desk. VINNIE You're fired. Leave your shirt and locker key. This bit of news hits Hal like a freight train. HAL Fired? Are you going to tell me why? VINNIE Showing up to work late. Showing up to work late drunk. Sexually harassing customers. Stealing from the register. HAL Vinnie, I don't know where you're getting these accusations - Vinnie takes out a video tape from his desk drawer and puts in a VCR. 15. HAL Oh, which one do you supposedly have here? VINNIE This is all of them at once. TELEVISION A WOMAN walks up to a BOWLING EMPLOYEE and hands him a pair of shoes. As the employee turns to the wall of shoes, a very drunk and disheveled Hal comes running in and pushes him aside. HAL I've got this one, Benny. So, Cinderella. Can I help you find your glass slipper? WOMAN Yeah, I'm looking for a seven. He folds his arms on the counter and leans into her with a cat-like grin on his face. HAL (with a leer) Seven - Well, maybe I could interest you in something in an EIGHT. Namely, me. Disgusted, she walks off screen. HAL Lesbo. Suddenly realizing the register's open, he quickly grabs a stack of cash and shoves it in his pocket. BACK TO OFFICE Vinnie turns off the television and waits for Hal to respond. HAL From the angle of the camera, I can see where you might have gotten the wrong idea. Listen, Vinnie, I don't think you've thought this through. If you fire me, who's gonna be captain of the alley's bowling team? 16. VINNIE Um, I don't know. Maybe somebody who can actually bowl. You guys have never won a game. I hired you because you said you were on the pro circuit. HAL No, I said I WILL BE on the pro circuit. VINNIE Please, a loser like you will never amount to anything. This harsh remark seems to leave Hal genuinely stunned. HAL Wow...If that's how you feel...I guess we should then talk about what kind of severance I'm gonna get. EXT. KINGPIN BOWLING - DAY TWO BRUISERS open the door and throw Hal out onto the street. He quickly picks himself up and turns back toward the building. HAL Hey...what about my ball? A bowling ball sails past him, just missing his head. HAL Thank-you! EXT. CHANNEL 7 NEWS BUILDING - DAY The massive building with a giant 7 on the roof stands in the heart of Metro City. INT. CHANNEL 7 NEWS BUILDING - OFFICE - DAY The cubicles and offices are alive with the hustle and bustle of a busy news day. Phones are RINGING, REPORTERS are TALKING, and Editors are SHOUTING. The elevator doors open and out steps Roxanne Ritchi. 17. Everything stops as the entire office suddenly falls SILENT. Somewhat taken aback by the reaction, Roxanne scans the room to see every eye on her. ROXANNE It's...um...It's good to be back. Thanks for everyone's cards and concerns. I really appreciated it - now I'm ready to climb back on the horse. No one is budging - their looks of pity are really starting to make her uncomfortable. The back office door suddenly opens and out comes FRANK BONIN, the gruff, middle-aged Producer of Channel 7 News. Noticing the silence, he looks up and sees the sad expressions on everybody's face. FRANK Someone die or something? He suddenly notices Roxanne - both feet are placed firmly in his mouth. FRANK (cursing himself) Oh, Jesus. ROXANNE It's okay. Frank quickly walks up to Roxanne and takes her gently by the arm. FRANK Come on into my office, sweetie. INT. CHANNEL 7 NEWS BUILDING - FRANK'S OFFICE - CONTINUOUS He sits her down on his leather couch, then quickly turns toward his door. FRANK Can we get this woman some water for God's sake? (to Rebecca) I gave you two months off. What're you doing back? People are gonna think I'm a slave driver. 18. ROXANNE Aren't you? FRANK Yeah, but I don't want people to think it. ROXANNE Frank, listen. I want to go back to work. I NEED to go back to work. FRANK ...You're hysterical, aren't you? Frank sits down on the couch and blankets Roxanne with A WARM EMBRACE. ROXANNE What're you doing? FRANK Keeping you warm before you go into shock. (toward the open door) DO I HAVE SLICE OPEN A CAMEL HUMP TO GET A GLASS OF WATER AROUND HERE? A SECRETARY quickly enters with a bottled water. She sets it on the table in front of them and leaves. Roxanne pulls herself out of Frank's grasp and stands up to face him. ROXANNE It was a traumatic experience. Yes, everyone knows Uberman and me were...close. But what I really need - what would really make me better is getting back to work. There's a sudden awkward silence from Frank. FRANK Well, that's going to be... ROXANNE I thought you'd be happy to have me back. 19. FRANK Oh, we are. Honey, nothing makes us happier than to have our girl back, but... ROXANNE Yes? FRANK Things have sorta...changed. ROXANNE In three weeks? FRANK Listen, I'm not one who likes to open up wounds - especially ones that are just starting to scab, but you were sorta our go to girl for the exclusive on Uberman. And now that he's gone...I moved Brad into your anchor spot. ROXANNE (disgusted) Brad? Brad Helms? The man is an idiot. FRANK It's the suits. They think it's time to switch things up. ROXANNE Oh, because they can't use me to get the big story. FRANK C'mon, Roxie. Using is in the nature of what we do. They used you, you used Uberman. Everybody's happy. ROXANNE (defensive) I didn't use him. FRANK Oh, I didn't mean that. I know you two were in love or something. My bad. ROXANNE We were. 20. FRANK And that's great. ROXANNE Very in love. There's a hind of self-doubt in Roxanne's expression, as if she's failed to convince even herself of this. ROXANNE Okay. So, where are they going to move me if Brad has my spot? FRANK ...Human interest. ROXANNE Bake sales and pet stories. FRANK I told them I wouldn't be surprised if you just upped and quit. You busted your ass for that desk. Roxanne can hardly get it out - she's busy swallowing her pride ROXANNE I'll take it. Frank looks up at her, not believing what he's hearing. FRANK What? EXT. ABANDONED METRO CITY LIBRARY - NIGHT Amongst the jungle of high rises, one small building stands out from the rest - A tiny, forgotten piece of 19th century Gothic architecture. LIGHTENING FLASHES, revealing TWO CONCRETE GARGOYLES holding a cracked plaque, reading: METRO CITY LIBRARY. INT. ABANDONED METRO CITY LIBRARY - NIGHT A mixture of old and new. Dusty Victorian furniture and dilapidated bookshelves sit side by side with pristinely futuristic machinery. The building has been converted into Master Mind's new SECRET LAIR. 21. In the center of the main room is a three storey tall GLOWING BLUE ORB. At the base of it is a sign that reads "Reactor - Don't Touch." We PAN OVER to the READING ROOM where Master Mind is sitting on a couch watching TELEVISION. REPORTER ON TELEVISION (O.S.) It's been nearly six weeks, and still no word on the whereabouts of billionaire playboy, and philanthropist, Wayne Scott. Tune in at 11:00 as we look into what has become Metro City's biggest mystery. TELEVISION NARRATOR (O.S.) We now return to "The Hero of our Hearts: The Uberman story." Einstein and Plato come into the room holding a BAG OF LOOT. EINSTEIN Just robbed the diamond exchange. MASTER MIND (feigning pleasure) Great, great. Put it on the pile. Einstein tosses it on a LARGE PILE of purloined valuables in the corner of the room. EINSTEIN Anything else today? MASTER MIND No. Master Mind turns his attention back to the screen. Plato sees that Master Mind is in a funk and tries to snap him out of it. PLATO (cheerfully) Sir, the new reactor is installed. Plato nods to the giant orb. PLATO Do you want to throw the switch? I know how you love to start reactors. 22. MASTER MIND Maybe later. Einstein gives Master Mind a funny look then exchanges glances with Plato before leaving the two of them alone. Without turning away from the TV, Master Mind addresses Plato. MASTER MIND (CONT'D) What is it, Plato? PLATO (nervously) Sir, I can't help but notice that you've been...a little down lately. MASTER MIND When I want your opinion I'll beat it out of you. PLATO Yes, sir, I know, but please forgive my impertinence. It's just that you seem to have lost your lust for our profession. You've stopped going on jobs and spend most of your time watching Uberman specials. Master Mind relaxes slightly and turns to face the window in a classically contemplative pose. After an overdramatic beat... MASTER MIND I have defeated my greatest enemy. I have free reign over Metro City. I have more wealth than a thousand Sultans. I've achieved all I have worked for...so why am I so unhappy? He walks over to a PAINTED PORTRAIT that looks almost exactly like him, except slightly older, maybe meaner - MASTER MIND'S FATHER. MASTER MIND I mean, my father, god rest his evil and tormented soul, raised me straight from the test tube to be a symbol of evil. (MORE) 23. MASTER MIND(cont'd) And, I have accomplished something he had only dreamed about - the destruction of Metro City's champion. I tell you, I've always lived with this unquenchable thirst. I thought it was to make him proud or to get absolute power. But now that I've pretty much accomplished both, I am at a loss. PLATO ...I sort of have a theory about all that. MASTER MIND (snippy) Oh, really? PLATO Well, for one thing, maybe Uberman was more important to you than you thought. MASTER MIND He was a worthy rival. Sometimes I wonder, did he consider me his evil equal or was I just an annoying, little gnat to him? ...What's the second part? PLATO I think you sort of have a thing for Roxanne Ritchi. Master Mind quickly takes his lackey by the throat. MASTER MIND YOU WORM! HOW DARE YOU! WHERE WOULD YOU GET SUCH A NOTION? PLATO Sir, your plans always involve Ms. Ritchi either being kidnapped or placed in danger. If that's not love, I don't know what is. It's the grown up equivalent of dipping her pigtails in the ink well. Don't you see? She's the one treasure that's always escaped you. From Master Mind's expression, we see Plato's words beginning to ring true. 24. INT. RESTURAUNT - DAY Roxanne is having lunch with several girlfriends sitting around her, gabbing. FRIEND #1 I can't believe you came back so soon. FRIEND #2 Are you sure it's not TOO SOON, honey? ROXANNE I just wanted to get back to work. FRIEND #3 What we need to do is get you back on the saddle...the love saddle. Friend 1 and 2 give 3 disapproving looks. FRIEND #3 It's been three weeks. FRIEND #2 She just lost the love of her life, Grace. A WAITER comes by with a tray of CAESAR SALADS and begins setting them out for the ladies. ROXANNE I keep trying to tell people it wasn't really like that. Uberman and I - We were kinda having problems. We broke up. The waiter ALMOST DROPS HIS TRAY AT THIS. The women are too shocked by Roxanne's revelation to notice. FRIEND #1 You broke up with Uberman! FRIEND #3 You must have REALLY, REALLY high standards. I mean, you were dating a god. I mean, what's it take? ROXANNE Maybe someone who's a little more aware of his faults. Someone a little more sensitive. 25. FRIEND #3 Right. Someone who listens, sexy but attainable with cute little cheeks like a hamster and heartbreak in his eyes. She turns to Friend one and two to explain. FRIEND #3 She wants John Cusack. FRIEND #2 The actor? FRIEND #3 No, the famous pediatrist - Yes, the actor. Ever since we were teenagers, Roxanne's totally had the hots for him. ROXANNE Well, until he miraculously comes walking into my life, I'm just going to take a little reflection time for myself. The waiter gets a confused look on his face then slips away as Roxanne and her friends continue to chat away. EXT. RESTURAUNT - DAY The waiter tosses his apron in a trash can, then rolls up his sleeve and presses A STRANGE LOOKING DEVICE STRAPPED TO HIS WRIST. His image gets staticy, like a TV station going out, then disappears - revealing the man's true form underneath: MASTER MIND! MASTER MIND Who the hell is John Cusack? EXT. CITY STREET - DAY A YOUNG MOTHER pushes her baby stroller past a building construction site. ACROSS THE STREET A local POLITICIAN addresses a group of REPORTERS on the sidewalk, including Roxanne. 26. POLITICIAN The Fifth Avenue Renovation Project, which I championed, will breath new life into the downtown area. New life means new jobs and new revenue. ROXANNE Councilman, is it true that your brother-in-law's construction company won the contract for this project? POLITICIAN Well...er...yes, but...look I'm not here to answer a lot of crazy questions... YOUNG MOTHER The young mother stops halfway down the block, reaches into the stroller and tries to comfort her now crying baby. Above her, a CRANE is maneuvering a pile of STEEL GIRDERS to an upper floor. Hal comes around the corner and heads in her direction. CRANE The crane GRINDS TO A HALT. The OPERATOR has a confused look on his face as he moves levers back and forth in an effort to fix the problem. Hal stops a few feet from the woman and stoops down to tie his shoe. CRANE The operator's hand slips off the lever, hitting a RED BUTTON. To his horror the crane DROPS ITS LOAD OF STEEL. HAL AND THE WOMAN The woman looks up to see the girders seconds from crushing her and her baby. She screams. Hal looks up and sees it as well. He starts to run out of the way and crashes into the woman and stroller. ACROSS THE STREET 27. The reporters turns their cameras just in time to catch on film what appears to be Hal pushing the woman to safety just as the GIRDERS CRASH TO THE GROUND. HAL AND MOTHER Tears of joy in her eyes, the woman picks up her baby and kisses it. Hal struggles to catch his breath as the mother turns to him. YOUNG MOTHER Thank you! Thank you for saving me and my baby! She hugs him with her free arm, weeping with joy. HAL (not knowing what she's talking about) Huh? He's a little uncomfortable with the woman's public display of affection and the small child in-between their embrace. HAL (CONT'D) There, there. Hal slowly eases out of the woman's grip. HAL (CONT'D) Okay, we better...well, I hear these little guys smother easy. The reporters rush over and surround Hal and the mother. ROXANNE What's it feel like to be a hero? Hal looks up at Roxanne. Instantly, he's captivated by her beauty. HAL Well...I'm just a man doing what men do. You're Roxanne Ritchi, aren't you? They're suddenly interrupted when another reporter pushes his way in between them. REPORTER Were you scared? 28. HAL Scared? Who had time? The reporters eat this up. INT. ABANDONED METRO CITY LIBRARY - NIGHT TELEVISION John Cusack stands in the rain looking up at a window of a two story house. He holds up a BOOMBOX and "In Your Eyes" by Peter Gabriel begins to play. From the couch, Master Mind and his minions watch. MASTER MIND John Cusack, huh? So all I have to do is have a cute puppy dog stare, be willing to make a fool of myself and - Oh, REMOVE BOTH MY BALLS. He turns to see Da Vinci watching the movie and wiping a tear from his cheek. MASTER MIND Please, get a hold of yourself. INT. BOOKSTORE - NIGHT Roxanne is carrying a large paper coffee cup in her hands as she peruses the isles. She sets it down on a shelf to pull a book out and ends up KNOCKING THE DRINK OVER. ROXANNE Shit. She goes to pick it up when someone bends down and picks it up for her. Looking up to thank him, Roxanne is suddenly stunned speechless - It's popular and critically acclaimed actor JOHN CUSACK, or rather Master Mind disguised as him. "JOHN CUSACK" Oh the humanity - it was a Venti. ROXANNE (stunned) You're...you're. "JOHN CUSACK" Yes, it's me. John Cusack...the actor. 29. He notices the book she's reading. "JOHN CUSACK" Hey, is that Shelly? Wait, I think remember something from that one - Let's see: "My head is screaming `I want you and need you' - my heart it keeps reaching to see you and feel you - yet in the end, I'm alone once again." Wow, I scare even myself. I'm sorry. I'm just really into poetry. Probably because I'm so sensitive and always going to great lengths to express myself. But enough about me. Can I fill you up? ROXANNE (captivated) ...Yes. (catching herself) I mean, excuse me? "JOHN CUSACK" Can I fill you up? Your coffee. ROXANNE Right. INT. BOOKSTORE CAFE' - LATER Roxanne talks as John Cusack listens to her every word intently. ROXANNE I did have a boyfriend - until fairly recently. She suddenly begins to feel the stares around her as passers- by being to notice who she's with. ROXANNE I'm sorry - this is so surreal! "JOHN CUSACK" Yeah, they charge way too much at these places - Now back to your boyfriend. I'm interested and compassionate. I want to know about you. 30. ROXANNE Things were complicated. He was a man married to his work. There was...there was a lot of competition in his line of business. I'm sure you know what that's like. "JOHN CUSACK" Sure. In my business, one thing I have is RIVALS. For example, mine is...uh...Lou Ferr...igno. ROXANNE ...The body-builder who used to play The Hulk on TV? "JOHN CUSACK" Did he? Well, we're always up for the same roles. Did your boyfriend have someone like that? A particular rival that was always getting his goat - so to speak? ROXANNE Well...one rival in particular seemed to get more of his attention than I ever did. But enough about my problems. "JOHN CUSACK" NO, TELL ME MORE!!! Suddenly realizing his outburst, he begins COUGHING to mask it. "JOHN CUSACK" (CONT'D) I'm sorry. I got a whooping cough. Had it ever since Serendipity. I WONDER WHERE OUR REFILLS ARE!!! (fakes cough) See, there it goes again. Please, go on. ROXANNE Right, well, he seemed to need him more than he needed me. "JOHN CUSACK" How do you mean? 31. ROXANNE It was conflict he thrived on. He always said he wouldn't know what to do with himself if Master - I mean, this guy were gone. It was like he needed it, like oxygen. The answer to his mental funk hits him like a bolt of lightening. He turns away from her as if for private time. "JOHN CUSACK" (almost to himself) I think I finally understand...The only logical answer is to recreate that rivalry - or if that's impossible, create one of equal structure. That's it! ROXANNE What? John Cusack snaps out of his dream-like haze realizing she's heard every word. "JOHN CUSACK" Oh, sorry, sorry. Just rehearsing for a part...where I play a man who talks to himself at inappropriate times. In a sudden rush, he rises out of his chair. "JOHN CUSACK" I have to go right now, but I'd really like to see you again - if that's alright. Roxanne looks up at him - She can't help but laugh at the craziness of the situation. ROXANNE I'd love that. INT. ABANDONED METRO CITY LIBRARY - DAY Master storms in the office to find Plato and Einstein playing darts with the original Mona Lisa. EINSTEIN Got her nose! MASTER MIND I've got it! 32. Everyone stops what they're doing upon seeing that their master has returned. MASTER MIND I've got it! MASTER MIND It's plain and simple. Extraordinary minds need extraordinary stimulation. Without that stimulus they wither and die. Therefore, there is only one logical conclusion: I must create a new superhero. EINSTEIN Yeah, maybe that's not such hot idea... MASTER MIND (ignoring him) Prepare for Operation Superhero Genesis! INT. ABANDONED METRO CITY LIBRARY - LABORATORY - DAY The lab is slick, white and ultra modern. Dressed in a lab coat, Master Mind enters through a SLIDING GLASS DOOR rubbing his hands excitedly. MASTER MIND Prepare the subject. He glances down into a large HOLE in the floor to see a naked thirty year old man, SEVERS, shivering. Above the hole, a huge vat dangles precariously. Master Mind steps behind a glass partition next to Plato and Einstein. MASTER MIND (CONT'D) Plato, pour the toxic waste. Plato throws a switch causing the vat to tip hundreds of gallons of green and brown goo into the hole. MASTER MIND (CONT'D) Drainage. The slime is sucked out through the floor, leaving a goo- soaked Severs. 33. Master Mind looks into the pit. MASTER MIND (CONT'D) Well, Severs? SEVERS I feel fine. Just a little sticky, but aside from that everything's completely - BOOM - Severs explodes. A hail of blood and tissue covers Master Mind and his men. For a good ten seconds nobody moves an inch. Finally... MASTER MIND Okay then. INT. ABANDONED METRO CITY LIBRARY - LABORATORY - DAY Through a glass WATER TANK we see a man breathing normally. MASTER MIND And this one? PLATO We attached gills to him. He can breath under water. MASTER MIND Ah. Does he have extraordinary strength? PLATO Well...no. MASTER MIND Can he fly? PLATO No. MASTER MIND Resilient to weapons fire? PLATO No. MASTER MIND He just breathes under water, then. PLATO Ah...yeah. 34. Master Mind rolls his eyes and walks away. INT. ABANDONED METRO CITY LIBRARY - LABORATORY - DAY The next guinea-pig, STENWICK, is standing in a sealed glass tube not much wider than himself. MASTER MIND Plato, the radioactive spider, please. Plato throws the switch DROPPING A SINGLE SPIDER onto Stenwick's arm. Stenwick looks and winces as it bites him. STENWICK Ow! He brushes the spider off. MASTER MIND Anything, Stenwick? STENWICK (shaken) No. Ah...sir, I didn't know this was about spiders. I have a pretty severe case of arachnophobia. Master Mind thinks for a moment, then turns to Plato. MASTER MIND We're gonna need more venom. Plato throws another switch, this time DUMPING THOUSANDS OF SPIDERS on poor Stenwick. His SCREAMS begin to fade as he's engulfed with swarms of crawling arachnids. MASTER MIND (CONT'D) How `bout now, Stenwick? ....Stenwick? INT. ABANDONED METRO CITY LIBRARY - OFFICE - DAY Master Mind is pacing back and forth. The muted TV plays in the background. MASTER MIND This has proven to be a challenge. I just don't know what I want. What do I want? 35. He stares at Einstein, Da Vinci and Plato, but they offer no advice. MASTER MIND (CONT'D) I want a man of moral fiber with a strong sense of right and wrong. Someone who doesn't seek power - instead, they must have it thrust upon them and find, within themselves, the courage to rise to the occasion. Einstein lets out a short laugh, getting everyone's attention. EINSTEIN Yeah, well, it sounds like what you want is Uberman. Master Mind snaps the fingers of his non-metal hand. MASTER MIND That's it! Why make a copy when the real thing will do? The lackeys look at each other, they can't believe what they're hearing. EINSTEIN I was just kidding, sir. In case you forgot, you actually burned Uberman alive. MASTER MIND Then we'll make a new one. Plato, bring me the box! MINUTES LATER Master Mind and the lackeys stand in a circle around a small table. Plato places a STAINLESS STEEL CHEST in the tables center. As Master Mind opens it, he's immediately doused in WHITE GLOW emanating from inside. MASTER MIND Behold - Uberessence. The very thing that gave Uberman his superhuman powers. 36. EINSTEIN Where the hell did you get that? MASTER MIND Oh, I shot him with a power sucking gun and had this idea to use this to clone a whole army of evil Ubermen. I'm not sure why I never got around to following up with that. PLATO I believe he defeated you before you could, master. MASTER MIND ...Right. Man, he was good! DA VINCI You want another volunteer, sir? MASTER MIND Not another volunteer driven by the need for personal gain. Somebody else, somebody pure. Master Mind turns to see an INTERVIEW WITH HAL playing on the muted television. Underneath his face is a blue caption with white lettering that reads: "Hal Stewart - Metro City's Newest Hero?" NEWS REPORTER ...who risked his own life to save that of a young mother and her child. HAL Please, please, you're embarrassing me. I saw someone in need and I helped them. What more can we ask of ourselves. I ask you, what more? A smile creeps across the evil one's face. MASTER MIND (CONT'D) Somebody like him! EXT. CITY STREET - DAY Plato is sitting in the van, staring into a pair of binoculars as he speaks on a cellphone. 37. PLATO Yeah, sir. This guy is a real piece of work. He used to teach bowling at Kingpin's. INT. MASTER MIND'S HIDEOUT - DAY Master Mind is sitting with his feet up on a computer console as he speaks to Plato. MASTER MIND (into phone) A modest profession to brilliantly hide his true heroic nature. I love it. EXT. CITY STREET - DAY PLATO Then you are absolutely going to love this - We follow Plato's line of sight across the street where we see HAL PLAYING WITH A LARGE GROUP OF BLIND CHILDREN. PLATO - He volunteers at a school for the blind. INT. MASTER MIND'S HIDEOUT - DAY Intrigued, he suddenly sits up in his chair. MASTER MIND He volunteers. He doesn't ask for any reward for his deeds. The fates are shining down on me. This Mr. Stewart is truly an unselfish soul. EXT. BLIND SCHOOL - DAY From a distance, Hal seems to be consoling an upset child who's sitting on a rock. But up close... HAL You greedy little bastard. I already gave you a twenty. BLIND KID Hey, you want me to play along? Then pay up, bitch! 38. HAL Fine, but you better be convincing. He gives the kid a bill out of his wallet and looks over his shoulder to see a HOT TEACHER walking toward them. HAL Here she comes, go to work. Like a miniature Brando, the blind kid buries his face in his hands and begins to cry. BLIND KID (weeping) Why can't I see! Why God? Hal puts a warm consoling hand on the weeping boy's shoulder. HAL Hey, Peter. C'mon champ, let me look at you. The Hot Teacher stops and curiously watches from a distance. The boy looks up at Hal, tears running down his dark sunglasses - he should get an Oscar. HAL You know, in life we're all given no more than we can bear. This happened to you maybe because you were meant to rise above it - Maybe to be an inspiration to the other little Peteys out there. BLIND KID You really think so, Hal? HAL Hey, does it LOOK like I'm lying? Now c'mon, go feel your way to class before you get your little butt suspended. The boy stands up and is about to take off. HAL Petey, wait a minute. Hal uses his shirt sleeve to wipe the tears away from the boy's face before sending him on his way. 39. The Hot Teacher grabs her chest. Her heart is about to absolutely melt. HAL Don't run into anything! EXT. STREET - CONTINUOUS Plato lowers his binoculars. From his perspective, Hal should be next in line for popehood. PLATO I think I've seen enough, sir. This is your guy. MASTER MIND (O.S.) (over radio) Then return to base. We have much work to do. Plato starts up the van and pulls away. INT. BAR - DAY It's a busy night. A couple of trucker types are shooting pool as the bartender slings drinks. Hal is nursing a beer at the bar when he suddenly notices a very ATTRACTIVE WOMAN sitting next to him. As he goes to straighten his stool-posture, Hal suddenly catches himself on the bar's TELEVISION - it's a story about how he saved the woman and her baby at the construction site. He turns back to the Attractive Woman next to him, then back to the TV. A plan of attack is forming. HAL (obviously playing it up for the woman's benefit) Oh, there it is again. This is really getting embarrassing now. The woman looks up at the screen and gives Hal a double-take. ATTRACTIVE WOMAN Oh my God! It's you! You're the man who saved that woman and her baby the other day! It is you, isn't it? TRUCKER #1, getting a drink at the bar next to them, OVERHEARS. 40. Hal rolls his eyes and puts his hands up in the air. HAL (to Attractive Woman) Oh, crap. You got me. TRUCKER#1 taps Hal on the shoulder. TRUCKER#1 Let me tell you something. That was just about the bravest damn thing I've ever witnessed. (he turns to the rest of the bar) Hey, everybody! This guy's the hero from TV! The bar ERUPTS IN CHEERS. MOMENTS LATER Hal is riding on the shoulders of TRUCKER#2 and TRUCKER#3 as `I'm Holding Out For A Hero' plays on the jukebox. TRUCKER#1 suddenly puts his hands in the air. The room quickly goes silent. TRUCKER#1 I want to give you something. He reaches into his pocket and takes out a medal. He holds it up in the air for everyone to see. TRUCKER#1 (CONT'D) Lost my whole platoon. They were a lot a good boys, a lot of good boys. That was just the way things were in "The Grenada." I'd rather a real hero have this. Trucker#1 gives the medal to a speechless Hal. ATTRACTIVE WOMAN Hey, you're on TV again. The crowd looks up at the Television. TELEVISION - CONTINUOUS The anchor man, BRAD HELMS (early 40's, amazing mustache), suddenly has a memo passed to him. 41. BRAD HELMS This just in. Upon a second look at that tape from this morning, which we'll now replay for you, it appears it was not the heroic act it first seemed to be. The tape shows Hal running in slow motion. BRAD HELMS (O.S.) (CONT'D) With the tape slowed down you can actually see the man push the woman and her child out of the way in an effort to save his own life. The tape shows Hal, in a clear act of self-preservation, pushing the woman and child out of the way. CUT BACK TO: INT. BAR - CONTINUOUS In unison, everyone turns their heads back to Hal. HAL I guess that looks kinda bad. Trucker#1 snatches his medal back. EXT. NEARBY ROOF - NIGHT Master Mind, Da Vinci and Plato look down, spotting Hal cutting through a dark alley. DA VINCI There he is, boss. Da Vinci hands Master Mind a fantastic looking silver rifle. MASTER MIND Now, we're sure this won't kill him? PLATO Yes, sir. He'll just feel a slight electrical shock. MASTER MIND Good. Master Mind raises the rifle and aims it at Hal. 42. EXT. ALLEY - NIGHT Hal wipes the blood from his nose with his shirtsleeve. A LIGHTENING BOLT suddenly zaps Hal in the back. His teeth spark and arc electrons as his entire body shakes and shudders violently. He finally collapses, knocking over a row of garbage cans. EXT. NEARBY ROOF - NIGHT An angry Master Mind slaps Plato. MASTER MIND Slight electrical shock? EXT. ALLEY - NIGHT Hal lies flat on his back, his jacket smoldering. Dazed, he slowly rises to his feet and looks up at the sky. HAL God, I hate the weather in this city. Hal walks off into the night as he attempts to slap the emitting smoke from his jacket. EXT. NEARBY ROOF - NIGHT Master Mind turns to Da Vinci. MASTER MIND Follow him. INT. HAL'S APARTMENT - NIGHT It's a dirty, small studio. Laundry lies everywhere, dishes are piled in the sink and the litter box looks like a minefield. Hal comes staggering in. Through his POV we see the lights wobble and streak like a hallucination. He shakes his head trying to clear thing up, but it looks worse. Hal makes his way to the kitchen table and plops down on a chair. The room begins to swim. His CAT jumps on the table and sits down in front of him. 43. From Hal's POV the cat's face looks like we're seeing it through a kaleidoscope. Hal seems fascinated by it. CAT You don't look so good, man. HAL I don't feel good. I was struck by freaking lightening. Suddenly Hal realizes his cat's talking to him. HAL (CONT'D) AAAAAAHHHHH! You can talk? CAT No, you're just hallucinating. By the way, we're out of orange juice. HAL AAAAAAHHHHH! Hal jumps up, trips over a cardboard box and knocks himself out on the coffee table. INT. HAL'S APARTMENT - MORNING Hal lies in the same position we left him last night. He sits up and grabs his head. He looks like he has the worst hangover in the world. Finally, he remembers last night. He looks around, but not really sure what he's looking for. HAL Man... Shaking his head, he walks to the kitchen and opens the refrigerator. He pulls out an orange juice container and puts it to his mouth. It's empty. As if suddenly remembering something he looks from the carton to the cat, who is busy cleaning himself. He shakes the thought from his mind. BATHROOM Hal lifts the seat and unbuckles his pants. 44. HAL'S FACE He stares at the ceiling with half closed eyes. The inevitable sound of urine hitting water starts. A content look washes over his face. There is a distinct sound of porcelain CRACKING and SPLINTERING. The sound intensifies. Hal looks down to see his URINE STREAM SMASHING THE TOILET. HAL (CONT'D) Oh, God! He whips his stream away only to cut a LONG RIP IN THE WALL. HAL (CONT'D) Oh, God! He freaks out and begins to lose control of his flow as it destroys everything he accidently aims at; the bathroom mirror, a bottle of cheap cologne, the bathroom window. HAL (CONT'D) Oh, God! He aims back for the toilet, which is pretty much rubble now, to see the floor give way. Finally, the pee stops and he glances down the hole. He sees his downstairs NEIGHBOR sitting at his breakfast table. He has a fork halfway to his mouth as he stares at the smashed toilet on his pancakes. EXT. STREET - DAY Hal turns the corner to see his bus pulling away from the stop. HAL Wait! He starts running after it. ZOOM - HE TAKES OFF LIKE LIGHTENING. HAL (CONT'D) Whoa, whoa, whoa! Unable to stop, he SLAMS INTO THE BACK OF THE BUS and falls back to the ground. 45. As the bus continues on he sees an INDENTATION of his torso right below the rear window. Stunned, to say the least, he rises to his feet. HAL (CONT'D) Something's not right here. He slaps himself in the face as hard as he can. HAL (CONT'D) Wake up! Wake up, Hal! HONK! Hal spins around to see a car barreling toward him. He goes to jump out of the way - ZOOM - he FLIES TWO STORIES UP, nails a building and comes crashing back down to the sidewalk. Hal sits up, disheveled and scared. HAL (CONT'D) Okay, okay. Let's get it together, man. He closes his eyes in an attempt to will back his sanity. HAL (CONT'D) This is just some sort of...episode. It will pass, it will pass. He opens his eyes and looks down the street. A BEAUTIFUL NAKED WOMAN is coming toward him. HAL (CONT'D) Well, not too fast I hope. As she passes him and turns the corner out of his view he catches ANOTHER NAKED WOMAN - an old disgusting one. HAL (CONT'D) Yes, fast, fast! He turns away from her in horror only to see AN ENTIRE BLOCK OF NAKED PEOPLE going about their business. He rubs his eyes and looks down the street again. Everyone has returned to a clothed state. 46. He relaxes a little until he looks down and notices that he's floating a foot off the ground. HAL (CONT'D) I think I need to go home. INT. HAL'S APARTMENT - DAY Hal's front door CREAKS as it slowly opens, revealing Master Mind. He walks over to the bathroom and smiles to himself as he notices the giant hole in the floor. MASTER MIND Welcome to your second birth, Hal Stewart. Master Mind continues to survey the room. He stops to look over a "KARATE KID" POSTER on Hal's living room wall. He focuses on the majestic image of Pat Morita teaching a young Ralph Macchio to kick. MASTER MIND (CONT'D) Instruction is very important in the formative years. Every hero needs a mentor, a father figure to look up to. He presses his special watch, causing his body to MORPH INTO THE SPITTING-IMAGE OF PAT MORITA. "PAT MORITA" Perfect. INT. HAL'S APARTMENT - DAY Hal enters, grabs a bottle of vodka from atop of the fridge and takes a long pull from it. VOICE (O.S.) A man will usually find that if he drinks from a bottle, eventually, the bottle drinks from him. Hal does a SPIT TAKE. In the corner a darkened figure stands. HAL Who are you!? 47. VOICE I am the guide on your journey. Fate has chosen you to be it's champion. Pat Morita steps out from the shadows. Hal passes out again. LATER We are close on Hal's face as his eyes flutter open. He appears to be lying on the couch. He hunches up on his elbows, looks around, but everything is as it seems. He lays his head back down. HAL Thank God. It was a dream. Man, I must be losing it. A voice sounds right next to his ear. "PAT MORITA" (O.S.) You know you're out of orange juice? Hal leaps up to find he's been resting his head on Pat's lap. HAL Jesus! This isn't happening, this isn't happening. Hal backs away and trips over a box. "PAT MORITA" Calm. All things must be filtered through calmness. HAL Bullshit! Sometimes it's best to freak out. "PAT MORITA" I think we must work on your attitude first. HAL Look I'm gonna call the cops in about two seconds if you don't get out of here. 48. Pat rises and walks to Hal. He's so calm it makes Hal calm. "PAT MORITA" Are you calm now? HAL Yeah, I'm okay. Pat slaps him across the face hard. "PAT MORITA" Good, because we've got a lot of work to do. Hal grabs his jaw. HAL What the hell was that for? "PAT MORITA" Rule number one: expect the unexpected. HAL Can you just tell me what this is all about? "PAT MORITA" The heavens are not in the habit of bestowing a gift such as this to just anyone. You are being rewarded for being a man of great moral fortitude with an unwavering belief in humanity. HAL That's me alright. "PAT MORITA" I am to train you so you may fulfill your destiny to defeat the great menace to Metro City: Master Mind. Pat gets up and walks toward the door. "PAT MORITA" (CONT'D) Come. HAL We're are we going? 49. "PAT MORITA" To train. EXT. PAT'S CAR - DAY Pat is sitting in the driver's seat. The car is bumping up and down. "PAT MORITA" Strength is just as much in the mind as it is the muscle. Remember, both need to be exercised. We PULL BACK to see Hal lifting the car up over his head. He's hardly straining. HAL I'M LIFTING A FREAKING CAR!!! Pat leans on the HORN. "PAT MORITA" Hey, Corky? You listening? Two highly attractive female joggers run by. They're clearly impressed with Hal's show of strength. He smiles and mouths a "hello." HAL Yeah, work both muscles. EXT. DESERT - DAY Pat cocks back the chamber of a .357 MAGNUM. He holds it up and carefully takes aim...at Hal's chest. "PAT MORITA" Trust me. HAL What are you doing!? "PAT MORITA" An invulnerability test. Something wrong? HAL Uh...yeah. I would prefer not to get shot. Do not fire that thing! Frustrated, Pat lowers the gun. 50. "PAT MORITA" You're bulletproof. HAL Okay, do you know that for sure? Pat quickly aims and fires. Hal lets out a high pitched scream as the bullet ricochets off his chest. "PAT MORITA" I do now. Hal looks down at his chest, not so much as a scratch. HAL You suck. EXT. SKY - DAY Hal is in the air flying in a sitting position. He's weaving back and forth. HAL Ice Man, I got a bogie on my tail. Two Russian Migs coming in hard and fast. "PAT MORITA" Hey! HAL What? Hal looks down to see Pat Morita yelling at him from the roof of a building down below. "PAT MORITA" What did I tell you? Stomach down, hands up. Hal sighs and assumes the proper superhero in-flight position. HAL God, I feel so gay. Pat's CELL PHONE begins to RING. He answers it. "PAT MORITA" (in Master Mind voice) What is it? 51. ROXANNE (V.O.) John? Pat panics. He looks up to make sure no one is in earshot. He sees Hal now doing somersaults in the air. HAL YEEEE HAWWWW! Pat turns his attention back to the phone, talking in his John Cusack voice. "PAT MORITA" (in Cusack voice) Yes, it's John Cusack. ROXANNE (V.O.) Hi, it's Roxanne. Listen, I...I really enjoyed talking with you the other day. "PAT MORITA" ...As did I. ROXANNE (V.O.) Great. God, I feel really silly, and if you have a lot going on I totally understand. But, I was wondering if you maybe wanted to have lunch. He can't believe what he's hearing. "PAT MORITA" (excited) I'd love to! He quickly recovers his composure. "PAT MORITA" (CONT'D) I mean, I AM a little hungry. ROXANNE (V.O.) Great. How does the park sound, around noon-ish? "PAT MORITA" Sure! ROXANNE (V.O.) Great, see you then. 52. Pat hangs up the phone and returns it to his pocket as Hal lands behind him. HAL WHOOOOA! Man, that is so cool. It's like fly - Oh my God, I almost said it was like flying. "PAT MORITA" For the rest of the day I want you to continue to practice your flying posture. HAL Why, where're ya going? "PAT MORITA" ...To do something...mysterious ...and Asian. HAL Say no more, bro. I'll just keep at it, then. EXT. PARK - DAY John Cusack and Roxanne eat WRAPPED SANDWICHES while walking through Metro City Park. ROXANNE How's your sandwich? "JOHN CUSACK" It's quite delicious. ROXANNE Hope you don't think I'm too forward. Some men are intimidated when a woman asks them out. I just find you really easy to talk to. "JOHN CUSACK" And I you. ROXANNE You know, you're not at all like you are in the movies. "JOHN CUSACK" I'm not? 53. ROXANNE Yeah. I don't know - You have this strange, refined way of speaking. "JOHN CUSACK" I do? That is most interesting. ROXANNE Anyway, when we were talking the other day I just felt, even though we only talked for a couple of hours, that we've known each other for years. "JOHN CUSACK" I know just what you mean. Roxanne bites into her sandwich. ROXANNE You know what? This sandwich is disgusting. She tosses it in a nearby garbage can. ROXANNE (CONT'D) Of course I already ate half of it. I wonder what that says about my character? "JOHN CUSACK" It means you don't give up on a sandwich. You see that it has potential, and you give it every chance to be all it can be. Roxanne smiles at his analogy. ROXANNE Thanks, but knowing me, I was probably projecting my expectations of what a lunch should be on the sandwich. It might have been okay at first, but I just made it bitter. John Cusack notices Roxanne's smile starting to fade. "JOHN CUSACK" Is that what happened with your last sandwich - I mean, boyfriend? 54. ROXANNE When I look back, I probably shouldn't of expected so much from him. He was already a giving person. You know, one of those go out and save the world types. "JOHN CUSACK" I've run into a few. ROXANNE I was selfish, I guess. I didn't want to share him with anybody else. "JOHN CUSACK" It sounds like he was a special man. ROXANNE They broke the mold. John Cusack arches his eyebrow in a very familiar manner. "JOHN CUSACK" Perhaps not. INT. ABANDONED WAREHOUSE - DAY Hal walks up to Pat Morita sporting a Lone Ranger-type mask and wearing a purple and red superhero costume. It's not unlike Uberman's except for a giant "T" on his chest. (From here on, Hal is referred to as TITAN) TITAN What's the "T" stand for? "PAT MORITA" Titan. TITAN What's that supposed to mean? "PAT MORITA" It's from Roman mythology. Zeus's father...oh, just go with it. You look perfect. TITAN I don't think this mask is big enough. Are you sure no one is gonna recognize me? 55. "PAT MORITA" It's fine, just don't slouch. It's all in the posture. He grabs Titan's shoulders like a proud papa. "PAT MORITA" (CONT'D) It is time. INT. BANK - DAY There is a long line of people snaked around the velvet ropes. They're all waiting for their chance at the one open teller window. Four men wearing BEATLES MASKS(JOHN,PAUL,GEORGE,AND RINGO)and CARRYING SHOTGUNS enter the bank. John fires a shot in the air, sending everyone into an immediate panic. JOHN Alright folks, this is a robbery. Nobody moves - yadda, yadda, yadda... Ringo jumps over the teller wall and starts stuffing bills into a bag. As John and Paul cover the crowd, George goes to the corner office and puts a gun to the BANK MANAGER'S head. GEORGE The safe. Let's go. BANK MANAGER Okay, just don't hurt anyone. GEORGE Yeah, yeah, yeah. George leads him out by the collar. CRASH - Titan smashes through the window and lands in a bold superhero stance with hands on hips. TITAN Well, boys, there's no need for all this just to get the free toaster. Paul cocks his gun. 56. PAUL What are you suppose to be? We move in for a nice dramatic close up. TITAN Justice. GEORGE Well, justice, suck on this... George, John and Paul open fire on Titan. He just stands there and yawns as the bullets bounce off him. With their guns empty the three just stare at him in amazement. TITAN Now it's my turn. He turns to George. TITAN (CONT'D) Hey, George, here comes the sun. Titan grabs George and throws him into a fluorescent light fixture in the ceiling. Paul tries to run for the door. Titan snatches the collar of his jacket. TITAN (CONT'D) Say, Paul, your mother should know...that you're a scumbag. He tosses Paul out the window and into a parked DELIVERY TRUCK. Titan turns around just as John hits him with the butt of his shotgun. It instantly breaks apart in his hands. Titan lifts him like a rag doll up into the air. TITAN (CONT'D) John, all you need is love... He throws John who lands on top of a cubical wall - GROIN FIRST. TITAN (CONT'D) ...and a good urologist. 57. Titan effortlessly hops over the teller wall to find Ringo cowering on the floor. He grabs him by the shirt and lifts him up. HAL Well, Ringo...um...um...you're under arrest. EXT. BANK - DAY Titan walks out of the bank with Ringo and George under his arm. He's suddenly swarmed by a group of television reporters, including Roxanne. Across the street is Pat Morita. He watches Titan's first news conference with great anxiety. BANK MANAGER (to Hal) On behalf of the First National Bank of Metro City, I'd like to offer you a reward for your act of bravery. He hands Titan a check. TITAN (reading) Ten thousand dollars! Titan looks over to Pat, who violently shakes his head no. TITAN (CONT'D) (unenthusiastically) I...can't except this. Law and order is it's own...um...reward. Pat gives him the thumbs up. Pat turns, suddenly seeing Roxanne with her camera crew. Captivated, his eyes lock on her. Meanwhile, Roxanne and her cameraman, SETH, are maneuvering around the crowd to get closer to Titan. BRAD HELMS (O.S.) Not so fast, Roxanne. They both turn to see Roxanne's reporter rival Brad Helms, Geraldo without the class, and his cameraman, FRANK. BRAD HELMS This story's mine. 58. ROXANNE Listen, Brad. We were just in the area. I was just trying to - BRAD HELMS I've been in this business long enough to know pretty well what you were "just trying to do." Besides, I heard you couldn't take the big game anymore and were put on fluff detail? Dejected, Roxanne turns and motions for Seth to turn the camera off. SETH You're not gonna take that from him, are you? ROXANNE He's right. Old habit, I guess. (to Brad) We'll get out of your way. As they walk off, Brad makes a comment to Frank loud enough for her to hear. BRAD HELMS Besides, I'm sure there's a pancake supper somewhere that needs covering. INT. ABANDONED METRO CITY LIBRARY - OFFICE - DAY ON TELEVISION We see the news conference on the bank's steps. In the corner of the screen is written: "recorded earlier." BRAD HELMS For months now, since the death of Uberman, the citizens of Metro City have been holding out for a hero. Well, it appears they won't have to hold out for much longer as a new costumed crusader has suddenly stormed onto the scene. Today, at the Metro Savings and Trust, a masked mystery man single-handedly defeated "The Fab Four Gang." Just who is this new caped avenger? Brad holds the microphone to Titan's face. 59. BRAD HELMS I'm sure all of our viewers are now wondering, what's the "T" stand for? TITAN It's a message to all the scum out there. Uberman may be gone, but Metro City has a new protector, and his name is "Tighten!" Another reporter leans in. REPORTER How do you spell that? We PULL BACK to see Plato and Da Vinci watching this spectacle. Master Mind is sitting with them, reading a NEWSPAPER. MASTER MIND (reading paper) Oh, for heaven's sake. I can't believe it. He misspelled his name. Master Mind holds up the newspaper. The headline reads "Metro's New Hero: Tighten." MASTER MIND (CONT'D) No matter, I suppose. Master Mind throws the paper on the floor and begins to pace around the room with his arms folded behind his back. MASTER MIND (CONT'D) We've now fully established Titan as Metro City's hero. They will love him just as they loved Uberman. Everything is going according to plan. Einstein leans over and whispers in Plato's ear. EINSTEIN (whispering) Yeah, if the plan is getting us in jail. Master Mind turns around, facing Einstein. He walks over, standing face to face with the rebellious henchmen. 60. MASTER MIND You know, Einstein, maybe I should have called you Socrates. He also didn't know when to keep his thoughts to himself. EINSTEIN I just fail to see the point in all of this. I mean, why are we creating another superhero when it was such a pain in the ass for you to get rid of the other one? I mean, Uberman is destroyed, we should be using this opportunity to...to... MASTER MIND To what? EINSTEIN I don't know. To take over the weather, space, the world - whatever super villains are SUPPOSED to do. MASTER MIND The reason someone like you will always be a minion is because you have no foresight. We take over the earth, like you said. Then what? Women? Cars? Money? Even the grandest treasures will lose their lustre if you don't have someone to hold them over. Einstein throws up his hands. He's had enough. He pulls off his wig and throws it to the floor. EINSTEIN That's it! This balance of the force bullshit is getting way too Oprah for me. I'm blowing. Who's with me? MASTER MIND You dare? EINSTEIN Yeah, I dare. I'm sick of wearing stupid costumes, and I'm sick of working for a super villain who's turning into a softie. 61. Plato and Da Vinci's mouths drop to the floor. They turn to Master Mind for his rebuttal. MASTER MIND What - did - you - call me? EINSTEIN You heard me. You used to be an inhuman monster, now look at you. You're creating super heroes, you don't go with us on robberies anymore, it's been days since you threatened anyone, oh, and not to mention this Roxanne Ritchi thing. MASTER MIND THAT is none of your business, knave! EINSTEIN Hey, you guys haven't sealed the deal yet, have you? MASTER MIND Silence! EINSTEIN (In a woman's voice) Oh, Master, your head is so big. MASTER MIND I'm warning you, Einstein. EINSTEIN (In a woman's voice) Take me! MASTER MIND I said silence! With his metal gauntlet Master Mind grabs Einstein by the throat and lifts him into the air. Einstein looks frightened as he tries to pry himself free of Master Mind's grip. Master Mind's eyes soften as if his heart is suddenly not into what he's about to do. He let's Einstein drop to the floor. MASTER MIND (CONT'D) Get out of my sight. 62. EXT. RESTAURANT - NIGHT Roxanne and John Cusack are eating on the outside patio of a fancy restaurant. ROXANNE Don't get me wrong, I love being a reporter. I don't think I could do anything else. It's the consequences of what we do that I'm having a problem with. He listens intently as he refills her glass with wine. "JOHN CUSACK" That's where journalistic responsibility comes in, no? ROXANNE It's supposed to. "JOHN CUSACK" Sounds to me like you're running from something. ROXANNE I got someone I cared about killed. If it wasn't for me, he wouldn't have been involved. John suddenly gets a disturbed look in his eye, realizing what she's talking about. He reaches across the table and takes her hand. "JOHN CUSACK" You can't blame yourself. My father used to say each of us must answer the great call to truly feel alive. ROXANNE Was he an actor? "JOHN CUSACK" ...No. He was...a landscaper. And a horrible one. I mean he would fail time and time again at his...landscaping. And sometimes he'd get pretty beaten up or thrown in jail - ROXANNE Jail? 63. "JOHN CUSACK" My point is he took the good with the bad. He grew a little each time. Improved, learned. ROXANNE Was he ever successful? "JOHN CUSACK" God, no...but don't let deter you. Roxanne LAUGHS. ROXANNE Thanks for this. You know, this is embarrassing, but it's been a long time since I - It's starting to lightly sprinkle. Roxanne looks up. ROXANNE (CONT'D) I think it's starting to rain. We might want to find a table inside. "JOHN CUSACK" What were you gonna say? ROXANNE Oh, I was gonna say...It's been a long time since...well, I've been with someone I...enjoy being with. John Cusack smiles warmly and raises his glass for a toast. "JOHN CUSACK" To people who enjoy being with each other. They go to clang glasses, when the rain suddenly causes John Cusack's disguise generator to short. His true form of Master Mind is briefly revealed to Roxanne as a BOLT OF ELECTRICITY encircles his body. Roxanne drops her glass and jumps out of her seat. MASTER MIND (CONT'D) Oh, no. Don't look at me. LIKE A BROKEN TV the image keeps switching between MASTER MIND AND JOHN CUSACK. 64. As Master Mind starts to franticly slap at his watch, the Cusack disguise begins to hold steady. He nonchalantly returns to cutting his steak. "JOHN CUSACK" Okay, never mind that. Now, where were we? Roxanne grabs his glass and throws the drink in his face, causing the generator to short out permanently. Master Mind now sits in his true blue form. ROXANNE Oh my God. MASTER MIND You're not gonna get all freaky about this, are you? ROXANNE This...this is too much, even for you. God, I go out with you, tell you my innermost thoughts. MASTER MIND I only did this because I wanted to talk to you on the same level. You know, without all the baggage? ROXANNE Baggage? You burned my boyfriend alive, you sick son-of-a-bitch! MASTER MIND You see, that's exactly what I'm talking about. Roxanne starts to walk away. MASTER MIND (CONT'D) Roxanne! ROXANNE Stay away from me. Master Mind sinks back down to his chair. Despite the now heavy rain bombarding him, he returns to his food. Several resturaunt patron's are looking at him through the window. 65. Our villain turns to them, giving them a villainous glare. MASTER MIND What? INT. MASTER MIND'S BEDROOM - NIGHT Master Mind is lying on his back, wide awake. MASTER MIND (mumbling to himself) Stupid. What was I thinking? Plato, it's his fault. He's the one who sent me on this weak-willed path. I'll filet his scrotum for this. Me, a creature of evil, in love with Roxanne Ritchi. Preposterous. I hardly give such matters thought He rolls onto his side. He yawns and closes his eyes. Suddenly, they shoot back open. CUT TO: EXT. ROXANNE'S APARTMENT - NIGHT Master Mind pulls up in a blue Rolls Royce, across the street from Roxanne's apartment He stares up at the building, hoping to catch a glimpse of her. Finally, she appears, primping her hair in her apartment window's reflection. MASTER MIND I should just go up there and just lay it all out to her. "Roxanne, I like you - I always have. Oh, and I'm sorry I blew up your ex. (realizing the absurdity of his words) Yeah, that would go over like a pants-less clown at a child's birthday party. What the hell am I even doing here? Who cares what she thinks? I'm a supervillain and here I am acting like a love struck schoolboy. Forget this. I control my own destiny! 66. He turns the ignition key - NOTHING HAPPENS. He repeats but gets the same results. MASTER MIND (CONT'D) (disgusted) Perfect. INT. ROXANNE'S APARTMENT - NIGHT She pulls a pack of smokes off her night stand. Empty. ROXANNE Damn. She grabs her long coat and throws it over her robe. EXT. ROXANNE'S APARTMENT BUILDING Roxanne steps outside. ROXANNE Please be open. Across the street is a liquor store. The light is still on. ROXANNE (CONT'D) Thank God. She walks across the street, passing in front of Master Mind's car. Spotting her, he sinks down in his seat. Roxanne walks by, totally unaware of his presence. Relieved, Master Mind sits back up and watches her go into the store. INT. LIQUOR STORE - NIGHT Roxanne walks up to an elderly Korean SHOPKEEPER at the counter. ROXANNE A pack of Lady Strikes, please. EXT. MASTER MIND'S CAR - NIGHT Master Mind is talking on his cell phone. MASTER MIND Hello, Triple A? 67. He suddenly spots something across the street. EXT. LIQUOR STORE - NIGHT A HOODLUM walks up to the entrance of the store and pulls out a gun from under his coat. EXT. MASTER MIND'S CAR - NIGHT Master Mind stares in shock. MASTER MIND I'll call you back. He hangs up the phone and watches the Hoodlum go inside the store. INT. LIQUOR STORE - NIGHT The Hoodlum reaches across the counter and grabs a fist full of cash from the register. SHOPKEEPER Hey! SHOTGUN HOODLUM Shut up, Gramps. He turns to Roxanne, spotting a GOLD NECKLACE around her neck. SHOTGUN HOODLUM (CONT'D) Gimme that necklace! ROXANNE I don't think so. The Hoodlum cocks his shotgun. SHOTGUN HOODLUM I said give it to me! MASTER MIND (O.S.) The lady said no. The hoodlum turns around to see Master Mind in the doorway holding a STRANGE-LOOKING HAND CANNON (GOO GUN) with knobs and blinking lights. The hoodlum starts to laugh. 68. SHOTGUN HOODLUM What the hell's that? A super soaker? MASTER MIND No, it's a goo gun. The hoodlum turns his gun to Master Mind. SHOTGUN HOODLUM Yeah, what's it do? MASTER MIND It goos. Master Mind fires the cannon. It instantly covers the store in a cloud of SMOKE. The smoke clears to reveal the hoodlum STUCK TO THE WALL, covered in a thick, GREEN GUNK. Roxanne stares at him, dumbfounded. MASTER MIND (CONT'D) It's...a prototype. Master Mind starts to walk out when he's suddenly confronted by the shopkeeper. SHOPKEEPER I know you! You Master Brain guy. You a hero. Master Mind points the goo gun at him. MASTER MIND Don't - EVER - say that again. EXT. LIQUOR STORE - NIGHT Master Mind walks out with the cannon resting on his shoulder like he's a short timer in Da Nang. Roxanne follows shortly behind him. ROXANNE Hey! Master Mind turns around. ROXANNE (CONT'D) Are you following me or something? 69. MASTER MIND Don't flatter yourself. He turns away and continues walking. Roxanne runs in front of him blocking his way. ROXANNE Don't walk away from me when I'm talking to you. Finally it occurs to her what's going on. ROXANNE (CONT'D) What a minute...all that stuff you use to say to me when Uberman was alive - about me being the loyal queen by your side as you rule over Metro City. That wasn't just super villain rhetoric, was it? You actually meant it! MASTER MIND My, someone has a rather high opinion of themselves. They stare at each other in silence, their glares locked in conflict. ROXANNE (coldly) Do you really think I would be with someone like you? This stings Master Mind to the bone. And after a brief contemplation, he reaches the only logical, painful conclusion. MASTER MIND No. With that, Master Mind exits into the night, leaving Roxanne with a baffled expression on her face. INT. ABANDONED METRO CITY LIBRARY - NIGHT Master Mind enters in a huff. Da Vinci closes the door behind him as Plato notices his master's agitated state. PLATO Everything alright, sir? Master Mind GRABS PLATO BY THE GROIN with his metal gauntlet causing Plato's eyes to bulge in pain. 70. MASTER MIND (overly calm) Fine, why do you ask? PLATO You...just...seem... Master Mind tightens his grip. MASTER MIND Go on. PLATO ...distracted. Master Mind releases him. MASTER MIND Just with business, my minion. Just with business. I've decided it is time. PLATO You mean? MASTER MIND Yes, we've created our hero, now it's time to give him a little motivation. DA VINCI How do we do that? MASTER MIND To be simply good is not enough. A hero must be driven by an almost relentless desire to right a wrong that can never be corrected. PLATO You mean? MASTER MIND Yes, he must lose someone near and dear to him - his father figure. Gentlemen, it's time for Operation Mentor Kill! EXT. SKY OVER METRO CITY - DAY Titan flies high over and through the city, under bridges, between buildings, etc. He's not really working, just enjoying himself. 71. INT. WOMAN'S APARTMENT - NIGHT A PRETTY WOMAN sits at her makeup table wearing nothing but her bra and panties. Through the reflection in her mirror we see a large window directly behind her. As she applies lipstick we see Titan fly quickly by in the background. After a moment he slowly slides back in view and begins ogling the girl. She sees him in the mirror and quickly covers herself with a robe. Titan tries to hide his face as he zooms off. MOMENTS LATER Titan looks down to see an APARTMENT BUILDING IN RUIN. Emergency lights flash around it as swarms of people run around in chaos. TITAN Man, what the hell happened down there? Wait a sec - He stops in mid-air as he comes to the striking realization. TITAN (CONT'D) THAT'S MY APARTMENT!!! EXT. HAL'S APARTMENT BUILDING - DAY Titan lands in front of the rubble that was once his home. Reporters stand just beyond the police line. TITAN Crap. From the wreckage crawls a dying Pat Morita. TITAN (CONT'D) PAT! Titan goes and kneels beside Pat, holding him in his arms. TITAN (CONT'D) You okay? "PAT MORITA" I'm dying, kid. There is just one last lesson I have for you. It is the most important of all. 72. TITAN What's that? "PAT MORITA" Master Mind did this, you must avenge me. TITAN Master Mind? Why? "PAT MORITA" Because he's evil. You must stop the evil Hal - stop the... Pat's body goes limp. The cameras begin to pop and flash around them. Titan gently lays Pat's body down and stands respectfully over him. The reporters rush over. REPORTER 1 Tighten, Is this the work of Master Mind? REPORTER 2 How will the death of your mentor affect your resolve? REPORTER 3 Was that Pat Morita? Titan walks up to one of the cameras. TITAN This injustice will not go unpunished. Master Mind, if you can hear me, Tighten is coming for you. In the background we see Plato and Da Vinci, DRESSED AS PARAMEDICS, load pat's body onto a stretcher. PLATO ACCIDENTALLY DROPS HIS SIDE. As he bends down to pick it back up, Pat quickly slaps him, then goes back to playing dead. INT. ABANDONED METRO CITY LIBRARY - NIGHT Master Mind and the boys prepare the fortress for Hal's revenge attack. Master Mind is as giddy as a schoolboy. 73. MASTER MIND Alright, people, we don't have much time. Titan should be here any minute, so let's get the lead out. There is a GIANT MOUNTED DEATH RAY in the middle of the hall being tinkered with by Da Vinci. MASTER MIND (CONT'D) How's the death ray coming? DA VINCI Nearly up to full power, sir. MASTER MIND Hum. Let's turn it down a few notches. It's his first time and we don't want to get in a lucky shot, now do we? Plato enters the room. MASTER MIND (CONT'D) Anything on the radar yet? PLATO Not yet, sir. MASTER MIND I see. Well, he must be planning something big. Are the flame androids deployed? PLATO All twelve. Master Mind rubs his hands in anticipation as he sits down on his throne. MASTER MIND Wonderful, wonderful. Plato, Da Vinci, take your places next to me. They move to either side of the chair. MASTER MIND (CONT'D) No slouching. Da Vinci straightens up and sucks in his gut. They remain this way for several long moments. Master Mind occasionally glances at a DIGITAL CLOCK on the wall. Still no Titan. 74. LATER Apparently quite some time has passed. The bold stances have degraded to fatigue. PLATO He's certainly taking his time. MASTER MIND He'll be here. That's the way it works. STILL LATER Master Mind reclines in his chair and taps his metal gauntlet impatiently on the armrest. Plato has squatted down, resting his chin on his hand. MASTER MIND (CONT'D) Unprofessional, that's what this is. No, it's disrespect for the craft. Master Mind rises and begins to pace back and forth. MASTER MIND (CONT'D) Would Uberman have kept us waiting like this? Of course not. He was a pro who knew the score. It's time we spelled out a few things for this Titan. I will not be made a fool of. He storms out of the room. INT. HAL'S NEW APARTMENT - DAY Titan's sitting on the floor in a barren apartment wearing his costume top and some tighty whities. He sips his beer as he watches a basketball game on a tiny TV. Much to his annoyance, there's a KNOCK at the door. TITAN Oh, for crying out loud. He gets up and opens the door. It's Master Mind. MASTER MIND Do you know who I am? 75. It takes a few moments to register, but Titan's suddenly excited. TITAN Yeah, you're Master Mind. Yeah! You're actually the guy I want to see! MASTER MIND Oh, so NOW you want to get down to it. Well, I want to get a few things off my chest first. Master Mind walks past Titan into the apartment. He spins around, pointing at him accusingly with one of his metal fingers. MASTER MIND (CONT'D) Of all the inconsiderate - Do you have any idea how long we waited for you? We're you even planning on coming to me and getting revenge? Titan shuts the apartment door, and turns back toward his guest. TITAN Well, at first I was going to. You know, because that's what I figured I was supposed to do. But then I got to thinking- MASTER MIND (interrupting) -You got to thinking? There's nothing to think about. I'm the villain. I do something bad, you come and get me. TITAN - I got to thinking...what's the point? Master Mind throws up his hands. MASTER MIND Maybe you're right. What's the point? He suddenly notices something in the corner of his eye. He walks over to a futon in the living room. On top of it is a LARGE SACK OVERFLOWING WITH GOLD WATCHES,RINGS AND OTHER VALUABLES. 76. MASTER MIND (CONT'D) What are these? TITAN That's what I wanted to talk to you about. MASTER MIND (baffled) Where did you get all this? TITAN (proudly) Get this: I stole them. MASTER MIND From where? TITAN From all over. You see, once you killed Pat and ruined my other apartment building I was pretty pissed off, so I figured I'd go, find you and kick some ass. Then I thought to myself: "Okay,then what?" I mean, if we were to fight, what would I get out of it? Would I get my apartment back? Would I be able to pay the bills? MASTER MIND Well, what about your mentor? TITAN Tell you the truth? He was kind of a dick. I mean, being a hero is dandy and all, but it's volunteer work. Now you've always had the right take on all this. I mean, when you rob a bank or take over the diamond exchange you get something out of it. I mean, when you don't get caught, which, no offense, isn't very often. And that brings me to what I wanted to propose to you: Who could catch you if I'm by your side? Perplexed by his proposal, Master Mind just stares at Titan awe-struck. MASTER MIND You want to team-up? 77. TITAN You got the brains, I got the brawn. We could even call ourselves that: `Brain' and `Brawn'. Look at this. Titan picks up a piece of POSTER BOARD off the floor and shows it to Master Mind. TITAN (CONT'D) I even designed us some new costumes. The picture is crudely drawn with magic markers and crayons. A big headed man (Master Mind) is standing on a plate of grass in a blue costume with a picture of a brain on his chest. Next to him, is a picture of Titan in a red costume with a black cape, but his chest is mysteriously blank. Titan proudly points to the two figures. TITAN (CONT'D) See, you'd be brain, so you got a little one on your costume, and then I'll have brawn on mine...once I figure out the best, you know, visual interpretation of it. What do you think? MASTER MIND What do I think? Master Mind shakes his head tiredly. MASTER MIND (CONT'D) I think you're probably the biggest idiot I've ever met. I mean, I can't believe you. All your gifts, all your powers, and all you want to use them for is your own financial fulfillment. You know what? Your kind of people make me sick. Titan puts down his drawing. TITAN I worked hard on this. MASTER MIND Oh - gee - I am so sorry! 78. Master Mind looks to Heaven in disgust. MASTER MIND (CONT'D) (under his breath) Of all the people to pick, it had to be this loser. This strikes a cord with Titan. TITAN Now, hold on. You're going a little too far. MASTER MIND I wish your mother said that to your father the night of your conception, they would have saved me a whole lot of heartache. TITAN Hey, I mean it. Master Mind gets right in his face. MASTER MIND Oh, yeah? What are you gonna do? EXT. HAL'S APARTMENT BUILDING - DAY We see Master Mind's body CRASH through the building and land in a DUMPSTER across the street. A car pulls up. The driver's door opens. Da Vinci gets out and runs to help his master. DA VINCI Master! MASTER MIND (O.S.) It hurts. Da Vinci peeks into the dumpster to see Master Mind's body cushioned by a stack of trash bags. DA VINCI What hurts? MASTER MIND It! The overly large henchmen starts to pull his master from the dumpster when they suddenly hear a voice from above. It's Titan peeking through the hole in his apartment wall. 79. TITAN I don't need you, I don't need anybody. I have the power to do and take anything I want. And now, I'm gonna take back everything this city owes me. Beware Metro City, it's time for Titan to collect. Titan shoots up into the air. TITAN (CONT'D) Oh, and from now on - I'M GONNA FLY THE WAY I WANT TO FLY! He takes a sitting position and flies away as if he were piloting an invisible jet. Master Mind climbs out of the dumpster and watches Titan disappear into the distance. DA VINCI How'd the plan go, boss? MASTER MIND I just made myself redundant, old friend. Da Vinci gives Master Mind a whiff. DA VINCI It's not that bad. INT. BANK - DAY Titan, with a happy bounce in his step, enters the bank. The last time he was here he thwarted a robbery. He looks nostalgic. A SECURITY GUARD shyly walks up to him like a kid meeting his TV idol. SECURITY GUARD Morning, Tighten. TITAN Morning. SECURITY GUARD Is there something we can do for you? 80. TITAN Oh, don't bother about me. I'm just here to make a withdrawal. Titan walks across the lobby, drawing stares of admiration from all. A little girl waves to him sweetly. He gives her a good- natured WINK as he heads straight for the vault. The security guard watches him enter and come out with a SACK OF CASH. Sure he must be misunderstanding what's going on, the security guard just stares at Titan as he passes by and out the door. The bank manager comes over to the guard. BANK MANAGER Say, did he just rob us? SECURITY GUARD Not sure. Sort of looks it, don't it? BANK MANAGER Yeah. SECURITY GUARD Should I, you know, stop him? BANK MANAGER Umm...Yeah. As the security guard exits the bank, the manager stares out the window. His eyes suddenly grow wide with terror. The guard's body suddenly smashes through the window, landing at the startled bank manager's feet. BANK MANAGER (CONT'D) (looking down at the guard) He did rob us, didn't he? CUT TO: TELEVISION "A Channel 7 News Special Report." Brad Helms wipes into view. 81. BRAD HELMS "Absolute power corrupts absolutely." When Lord Acton stated that, in a letter to Bishop Mandell Creighton in 1887, no one thought much about it, but today Metro City is reeling from that very prophecy. Tighten, who many thought of as our savior, has turned his back on the cause of justice. CUT TO: TITAN BEING EVIL - MONTAGE EXT. DIAMOND EXCHANGE - DAY Titan flies through the window of the building. He emerges seconds later laughing with his shirt full of booty. EXT. CITY STREET - DAY A woman screams from the window of a BURNING BUILDING. Titan flies up to her, grabs her fur coat and zooms off again, leaving the woman behind, slightly confused. EXT. OUTSIDE MARKET - DAY Titan steals a little boy's lollipop and gooses his mother. EXT. CITY STREET - DAY Dozens of people run through the streets apparently to get out of a downpour. We cut to the top of a building and see Titan ZIPPING UP HIS PANTS and laughing. INT. ABANDONED METRO CITY LIBRARY - NIGHT Master Mind paces back and forth in front of Plato and Da Vinci. PLATO I don't understand it. He seemed to have every characteristic we were looking for in a superhero. MASTER MIND Well, there's no use crying about it now, we must take action. I'm not going to play second fiddle to that crass buffoon. We must destroy Tighten. 82. PLATO It won't be easy. Uberman had a sense of decency and genuine love for the people. That was his weakness and was easily used against him. MASTER MIND Yes, but he possesses the same flaws present in Uberman's DNA - copper. It's like Benjamin Franklin always said: "If something works don't dick with it." EXT. BAR - DAY It looks like a war zone passed through here. Smashed police cars and debris lay everywhere. This seems to be the only building left untouched. INT. BAR - DAY A very tipsy Titan is sitting at the bar, looking deep into the bottom of his beer glass for answers. TITAN I can have anything I want. I'm like a god. The BARTENDER just listens as he wipes down a glass with a dirty rag. TITAN Point to any woman in this bar. I could have her in a second. He follows the bartender's gaze to THE ONLY OTHER PERSON THERE - A passed out, MIDDLE AGED HAG OF A BARFLY. TITAN (to Old Barfly) Hey, you wanna get with this? BARTENDER Buddy, what do you want? Titan carefully considers this for a moment. TITAN What do you want? That's the question, isn't it. I mean, what do you want when you can have everything? (MORE) 83. TITAN(cont'd) I suppose what I really want is to never be forgotten again. I want to do something that can never be cast aside or one-upped. I want a - what's it called? - A legacy. I want a legacy. Yeah, that's it. I like the sound that. BARTENDER I meant, what do you want to drink? TITAN Oh. EXT. BAR - LATER Titan stumbles out of the bar, carrying a large sack of money. MASTER MIND (O.S.) Your time has come to an end, Titan! He looks up to see Master Mind suddenly standing before him. TITAN What? MASTER MIND There can be only one master criminal in this city - and it's me. TITAN Really? Titan melodramatically throws up his arms. TITAN (CONT'D) I guess I should leave town then, huh? MASTER MIND I have a better idea - NOW! Two floors up Da Vinci releases a rope. A COPPER CAGE, like the one that caged Uberman, drops down on top of Titan. Titan nonchalantly surveys the cage. He walks to the bars, tries to pull them apart but can't. MASTER MIND (CONT'D) That's copper my good man. Your one weakness. (MORE) 84. MASTER MIND(cont'd) For all your amazing gifts of brawn you are no match for my intellect. Titan thinks for a moment. Suddenly, he starts to SPIN like a human top, DRILLING HIMSELF INTO THE STREET BELOW. As he disappears beneath the surface, we see a shocked look on Master Mind's face until Titan suddenly explodes out from under the street in front of him. Master Mind stares up at him, dumbfounded. Titan makes like he's going to strike him down, but stops. TITAN You know what? You're nothing but a bug. Not even worth my effort. He turns his back to Master Mind and continues down the street. Plato makes his way from the shadows to join his master. They watch Titan shrink into the distance. MASTER MIND He's not as dumb as I thought. PLATO I guess not...Funny, though. MASTER MIND What's funny? PLATO Funny Uberman didn't think of the same thing. EXT. HIGH ABOVE METRO CITY - DAY As Titan flies, he looks down at the rooftops of the city below. Suddenly, something catches his attention. HAL That's it! He stops, hovering in place as he looks down below. The buildings, which make up the heart of downtown Metro, are in a PERFECT TRIANGLE with a long strip of street leading up to it. It sorta looks like a bowling lane. 85. HAL Hello, Legacy. EXT. KINGPIN BOWLING - DAY Vinnie and his goons come running out as the hear a COMMOTION. They look up to see Titan ripping off THE GIANT BOWLING BALL from the top of the establishment. VINNIE Hey, that's my ball! INT. ROXANNE'S APARTMENT BUILDING - DAY Roxanne enters the building's elevator. Just before the door closes an ELDERLY WOMAN slides in. ELDERLY WOMAN That was a close one. Sixth floor, please. Roxanne smiles and goes to press the button. The elderly woman suddenly pulls out a SPRAY CAN, shooting a MYSTERIOUS-LOOKING MIST into Roxanne's face. She falls to the floor unconscious. INT. ROXANNE'S APARTMENT - DAY Roxanne awakens, finding herself tied to a chair in her living room. We hear NOISE from a TV in the background as she tries to adjust her vision. Slowly, the blurry figure before her becomes clear. It's Master Mind. He sits on her Lazy-Boy, reading what looks to be some kind of JOURNAL. MASTER MIND Wow, I always thought Uberman was your first superhero - but it looks like our little Roxanne dated a linebacker in college. ROXANNE That's my diary. MASTER MIND So it is. 86. ROXANNE It's personal. MASTER MIND Well, then I wouldn't leave it in your underwear drawer for just anyone to find. He throws the diary over his shoulder. ROXANNE What do you want? MASTER MIND I need your help. ROXANNE So you knock me out and tie me to a chair? MASTER MIND You're not going to like what I'm about to tell you. As she tries to shake off her headache from being knocked unconscious, Roxanne spots something on the TV. ON TELEVISION Brad Helms is huddled behind a van. BRAD HELMS It's chaos here in city square as city police - Behind him, Titan picks up a POLICE CAR and throws it at a PADDY WAGON. Both vehicles EXPLODE on impact. BACK TO SCENE ROXANNE He's really out of control. MASTER MIND Tell me about it. As if finally realizing something, Roxanne looks back at Master Mind. ROXANNE I should have known. You have something to do with this, don't you? - With Titan turning evil. 87. MASTER MIND Well, the evil thing he did by himself. My goal was to give MYSELF purpose by creating an intellectual sparring partner. ROXANNE (confused) You're talking like you made him. MASTER MIND And they call me Master Mind. ROXANNE Let me get this straight. You missed getting your ass kicked, so you made a new guy to kick your ass. That's pathetic. MASTER MIND In hindsight... Roxanne turns back to the TV to see a group of POLICE OFFICERS open fire on Titan. The bullets just deflect off his chest. ROXANNE And his powers, they're just like Uberman's. Why would he have his powers? MASTER MIND (almost ashamed) I had some left over from something. I infused him with it. ROXANNE YOU DID WHAT!? Driven by rage, she struggles to tear out of her bonds. She finally relents, giving Master Mind a look fueled by pure hatred. MASTER MIND Yeah, that's why I decided to tie you up. ROXANNE You did all this because you wanted purpose? MASTER MIND He seemed nice. 88. TELEVISION Titan is standing on top of a destroyed police car. He waves for the camera to zoom in on him. TITAN Closer. I want to show the people my real face. He pulls off his mask, revealing himself as Hal Stewart to the public for the first time. TITAN (CONT'D) Recognize me? BACK TO SCENE ROXANNE Hal Stewart. He's the guy we thought saved that woman and kid. Turned out he was just trying to save his own ass. MASTER MIND Yeah, good to know - NOW! TELEVISION Titan throws the mask over this shoulder and hops off the car. TITAN That's right, I'm really Hal Stewart. Former hero and bowling teacher at Kingpin's Bowling. BACK TO SCENE Roxanne turns to Master Mind, condescending him with her eyes. ROXANNE You picked a bowler to give super powers to? MASTER MIND It's a modest profession! TELEVISION 89. TITAN With my new found power, I've recently started to wonder what sort of legacy I should leave. Should I be a hero? I tried that once before - even saved a lady and her baby from being squashed. I was treated like a god until everyone started to shit on me - Okay, so what if I didn't "purposely" save them! He walks over and puts his hand on a large circular concrete shape just off camera. TITAN Well, I'm going to make something that can't be taken away from me. I'm going to create a permanent monument to my greatness. One that won't be so easily forgotten or erased. The camera pulls back revealing THE GIANT CONCRETE BOWLING BALL from Kingpin's. TITAN I intend to create a new category in the Guinness Book of World's Records by rolling the biggest strike in the history of bowling. He grabs the camera and points it to the DOWNTOWN BUILDINGS. We realize they are PERFECTLY ALIGNED IN BOWLING PIN FORMATION. TITAN My thanks to the city planning commission. This wouldn't have been possible without them. Titan grabs the camera so it's pointing back at him again. TITAN Tell your friends and family to tune in right here to this station at noon tomorrow. BACK TO SCENE ROXANNE My god, he's nuts. That'll destroy the whole business triangle. 90. Master Mind seems to be contemplating something - something bad. ROXANNE What? MASTER MIND My lair is in the direct path of the ball. ROXANNE Oh, real nice. Wouldn't want anything to happen to your hideout, would we? MASTER MIND You don't understand. I have certain equipment that's - that's highly unstable. ROXANNE What do you mean? MASTER MIND I sort of have a hydrogen reactor, okay? ROXANNE A HYDROGEN reactor? MASTER MIND It's experimental - only one in the world...Well, how do you think I power all my inventions? Someone like me can't pay for electricity. The bills would be outrageous. ROXANNE A REACTOR? MASTER MIND It creates 100 times the output of a nuclear one...If destroyed it could... ROXANNE - Vaporize the entire city! MASTER MIND (proudly) Pshaw...the whole eastern seaboard, actually. That little baby is amazing. I'm quite proud of it. (MORE) 91. MASTER MIND(cont'd) (off her deadpan reaction) I mean...we'd better find a way to stop him. Master Mind thinks a moment. MASTER MIND Did Uberman have a hideout? ROXANNE What? MASTER MIND A cave, a solitary fortress of some kind. C'mon, all heros have a place to hang their capes up in. Roxanne, it may be our only chance to find something, a clue, anything that could give us a fighting chance. ROXANNE It's under his house. MASTER MIND Whose house? Roxanne can hardly believe what she's telling him. ROXANNE Wayne Scott's. Master Mind shoots up out of his chair. MASTER MIND Wayne Scott? Uberman was Wayne Scott!? Wayne Scott, the wealthy philanthropist? But he disappeared - ROXANNE (interrupting) He disappeared just over two months ago when you killed him. Not only did you rid the world of a hero, you killed a kind, noble, generous man. Perhaps ashamed, the super villain hangs his head. Master Mind walks behind Roxanne and undoes her bonds. Rubbing her wrists, she watches him as he walks over to the door. 92. ROXANNE (CONT'D) Looks like you got what you always wanted. Uberman is out of the picture and Metro City is doomed. He grabs the door knob and stops, considering her words. MASTER MIND "Metro City doomed." You know, I never thought I'd say something like this, but here it goes - He slowly turns to her, CUE HEROIC MUSIC. MASTER MIND (CONT'D) Not if I have anything to say about it. EXT. WAYNE SCOTT'S MANSION - NIGHT Master Mind stands before the huge, Gothic structure in awe. MASTER MIND Such a dark place for one such as you. I wonder, underneath your noble deeds, what inner demons drove you to your endless crusade for justice? He walks to the front entrance. The double doors have been sealed shut with boards and nails. Master Mind begins to tear them off with his metal hand. INT. WAYNE SCOTT'S MANSION - NIGHT The doors opens. A beam of moonlight immediately pierces the darkness, forming an illuminated path into the heart of the manor. Master Mind enters. Covered in dust and cobwebs, the hall looks like a gigantic crypt. MASTER MIND Good lord, man. You've only been dead for two months. Master Mind walks, coming to a gigantic painted PORTRAIT OF WAYNE SCOTT. He stops to reverently admire the image of his fallen foe. 93. MASTER MIND (CONT'D) A disguise so simple, it's ingenious. No wonder I never caught on. Besides the Armani suit, there's nothing to hide the fact that this is the same person as Uberman. In the picture, he's even standing in the same cheesy, heroic pose with his fists on his hips. MASTER MIND (CONT'D) Two lives, yet in both you were an ideal. Perhaps it was you who was victorious in the end, old friend. A BONGING sound suddenly bellows through the dark halls. Master Mind comes to a grandfather clock standing next to a gigantic BOOKCASE. On the twelfth bong it falls silent. Master Mind begins to slide it across the floor until he hears a loud CLICK. The bookcase slides into the wall, REVEALING A HIDDEN PASSAGE. MASTER MIND (CONT'D) I'll miss how predictable you were. The passage way leads Master Mind to a WORKING ESCALATOR. Master Mind gets off the escalator to see a long hallway with stone walls. He begins to hear strange SOUNDS, almost like MUFFLED SCREAMS, coming from a doorway at the end of the hallway. Master Mind starts walking towards it. As he steps closer, he begins to notice a light cracking through the bottom of the door. MASTER MIND (CONT'D) Hello? Anyone here...besides..all the BIG MEN who are with me now? Nothing. MASTER MIND (CONT'D) (to himself) What's the worst you're gonna find? (MORE) 94. MASTER MIND(cont'd) The man was a boy scout, not a serial killer. He opens the door to his immediate amazement. It's some kind of screening room. A PROJECTOR shoots an image onto A DIRTY WHITE SCREEN hanging on the wall. BEER CANS litter the floor; a table in front of a ripped-up couch is covered in discarded snack goods; and a Kiss Pinball machine stands in the far corner next to a CLOSED DOOR. Master Mind turns his attention to the action on the screen. SCREEN A woman dressed in a leather DOMINATRIX OUTFIT is whipping an overweight man lying on a swing-like device with his butt sticking out. DOMINATRIX IN FILM YOU ARE A WORM! She whips him three times. The man CRIES out in pain. FAT MAN IN FILM PINEAPPLE!!! PINEAPPLE!!! Master Mind's eyes are transfixed on the disturbing imagery. The door by the pinball machine suddenly swings open. WAYNE SCOTT, dressed in raggedy sweats, steps into the room carrying a CAN OF BEER and a bowl of JIFFY-POP. Master Mind cannot believe his horrified eyes. MASTER MIND Ahhhhhh! Wayne Scott is just as startled. WAYNE SCOTT Jesus! He drop his drink and snack to the floor. The two men stare at each other as they struggle to regain their normal breathing patterns. Wayne Scott walks over to the couch, brushes off a thick layer of chip crumbs, and sits down. WAYNE SCOTT (CONT'D) What the hell are you doing here? 95. MASTER MIND I might just ask you the same question. I had thought I incinerated you. WAYNE SCOTT You scared the bejesus out of me. How'd you figure out I was still alive? Wait, how do you know my identity!? MASTER MIND Roxanne told me. As for your ruse, I forgot to line the bottom of the copper cage - Somebody pointed that out to me recently. Figured if they could do it, so could you. But one thing I couldn't figure out - WAYNE SCOTT The skeleton? Something I "borrowed" from a medical school a few months before. MASTER MIND A few months? How long had you been planning this? WAYNE SCOTT I always planned to retire - eventually. I mean, come on, you can't do this sort of thing in your fifties. You'd just look ridiculous. The pieces of the puzzle appear to be coming together in Master Mind's head. MASTER MIND I see it all so clearly now. INT. MASTER MIND'S HYDROFOIL - FLASHBACK Master Mind and his minions cover their eyes as the observatory explodes. MASTER MIND (CONT'D - V.O.) You must have done it just seconds before the observatory exploded. 96. INT. OBSERVATORY - FLASHBACK Similar to what Titan did, Uberman bores out from under the cage. MASTER MIND (CONT'D - V.O.) You bore out from under the cage. Then, using your Uber-Speed, - EXT. OBSERVATORY - FLASHBACK Running in a blur-like haze, Uberman screeches to a halt in front of some bushes. MASTER MIND (CONT'D - V.O.) - you made your way to safety, where you had the skeleton safely hidden away somewhere. EXT OBSERVATORY - SKY - DAY Uberman soars high above the clouds. He looks down at the observatory, which is a mere speck in the distance. MASTER MIND (CONT'D - V.O) (CONT'D) Then you must have flown to a safe distance and waited for the explosion, then... Just as the observatory explodes Uberman aims and throws the SKELETON like a javelin. It soars through the air like a missile, tearing through the flames of the explosion, and crashing right into the windshield of Master Mind's hydrofoil. END OF FLASHBACK Wayne stares at Master Mind, clearly impressed. WAYNE Man, you ARE smart. MASTER MIND But why fake your death? Why go through all of it? You could have just quit. WAYNE SCOTT But the responsibility would still be there. (MORE) 97. WAYNE SCOTT(cont'd) A cop can retire and stop handing out speeding tickets - but people expect more from superheroes. I tell you, a volcano couldn't erupt in Zimbabwe without everyone expecting me to do something about it. I figured, out of sight, out of mind. MASTER MIND And Wayne Scott? Why did he have to disappear? WAYNE SCOTT Both of my lives have so much baggage. It's time for new baggage, you know? Master Mind's is absolutely flabbergasted. MASTER MIND I just can't believe it. This whole time you've been in hiding while a force of great evil is tearing your city apart? Wayne rises to his feet, waving his hands for Master Mind to say no more. WAYNE SCOTT I don't want to hear about it. That's why I don't have a television in here to remind me of all the things I SHOULD be doing. Hell, I could get a wife to do that. MASTER MIND There's a demented supervillain out there about to destroy our - I mean, your city. Wayne shrugs indifferently. MASTER MIND You're really going to do nothing? WAYNE SCOTT Good and evil have a way of balancing themselves out. If this guy is as bad as you say, somebody will rise up to fight him. It's just the order of things. You found me, didn't you? 98. Wayne puts a condescending hand on Master Mind's shoulder. WAYNE SCOTT (CONT'D) I know it's hard, but you'll find someone else someday. He then starts walking to the door. MASTER MIND You're the only one who can stop him. Wayne turns around. WAYNE SCOTT Couldn't if I wanted to. Gotta a plane to catch. MASTER MIND A plane? WAYNE SCOTT Going to Barbados for a little change in climate. Now, if you'll excuse me, I got to go pack. He reads the still defeated look on Master Mind's face. WAYNE SCOTT (CONT'D) You were a good foe. I'm sorry if I've let you down. If it makes a difference, you were the best foe a hero could ask for. MASTER MIND Not smart enough to come up with a full-proof trap. WAYNE SCOTT Well, you did almost have me when you figured out my weakness was copper. Now that made me sweat a little. Took me way too long to drill out from under that cage. MASTER MIND I got lucky. WAYNE SCOTT Anyway, it's a good thing for my sake that I could always count on you for an out. 99. MASTER MIND (suddenly confused) What do you mean? WAYNE SCOTT C'mon, we always threw each other a couple of bones. You would always leave me an out in one of your `full-proof' traps, and I'd never had you incarcerated at a penitentiary that you couldn't eventually escape from. It kept our little game going. Master Mind seems deflated. MASTER MIND Game? - Was that all this ever was to you? You know, I was trying my best every time I fought you. Those `outs' as you call them were unintentional. WAYNE SCOTT Oh. MASTER MIND I guess I was never really a match for you, was I? Wayne shrugs. MASTER MIND (CONT'D) (thoughtfully) Then how can I expect to be one for Titan? A beaten man, Master Mind heads for the door, but stops and turns around. MASTER MIND (CONT'D) What about Roxanne? Wayne unleashes an exhausted sigh. WAYNE SCOTT I think we both got what we wanted out of our relationship. She got a career out of me, and I got plenty of other things out of her. But I'm ready to move on to greener pastures. 100. Master Mind's steel hand clinches into a fist at his side. Wayne's oblivious to this. MASTER MIND I guess I wasn't the villain I thought I was, and you...you weren't the hero I thought you were. He turns to make his exit when he suddenly sees ROXANNE STANDING IN THE DOOR FRAME. Wayne is almost at a loss for words. WAYNE SCOTT Roxanne! How long have you been... ROXANNE Long enough. Roxanne looks at Master Mind. ROXANNE (CONT'D) Don't you have something else you can go do? Master Mind leaves Roxanne and Wayne facing each other in silence. EXT. ANOTHER BAR - DAY Titan emerges with Brad and Frank. He's holding a BEER CAN and a bag of PORK RINDS. TITAN Alright, I want this whole thing to look ESPN professional, understand? A distant MECHANIZED RUMBLE can be heard. The noise rises, signaling the approach of something powerful. Titan and his crew walk out to the center of the plaza as the sound becomes almost deafening. A TANK TRACK as it moves over the street. We PULL BACK to see a whole line of TANKS rolling along the street. PLAZA From the five streets branching off the plaza, a dozen tanks roll toward Titan. 101. Titan turns to Brad and Frank. TITAN (CONT'D) You guys are about to get some good footage. I might need a little room, though. Brad and Frank look at each other and run to take cover behind a nearby building. Meanwhile, Titan nonchalantly sips from his beer as the tanks begin to surround them. FEEDBACK belts out of one of the tank's loudspeaker's, causing Titan to do a mock wince. TANK LOUDSPEAKER Titan, we have orders from the city of Metro to take you into custody. If you do not give your self up willingly, we will be forced to open fire. There's a long pause as no one says anything. TANK LOUDSPEAKER What is your answer? Titan takes a sip of his beverage and UNLEASHES A GIGANTIC BURP - The shockwave of which sends several of the tanks flying into a nearby building. Two of the remaining tanks close in on the villain. Both have him dead to rights at point-blank range with their massive guns. Titan sets down his beer, then calmly plugs a fist into each barrel. They FIRE. The FORCE OF THE BLAST SENDS THEM BOTH FLYING IN OPPOSITE DIRECTIONS where they CRASH into nearby buildings. Titan bends down and pick his beet back up. TITAN (to beer) Miss me? Titan is suddenly bombarded by a massive barrage of machine- gun fire. The force sends him flying into the windshield of a nearby car. 102. He looks up to see an APACHE ASSAULT COPTER. It's nose- mounted GATLING-GUN is turning toward him. Titan gets up to his feet and looks down at his beer can. The bottom of it was blown apart in the blast. TITAN (CONT'D) Didn't mean to get you involved in all of this. He stared daggers up at the helicopter pilot just as the gun gets a bead on him. TITAN (CONT'D) Hey, man! You killed my suds! Titan throws the can up and slaps it with the palm of his hand. It flies with so much force it knocks the helicopter blade clean off. The rest of the Apache crashes to the street like a car dropped off a building. TITAN (CONT'D) That's one was for you, beer. Titan salutes the wreckage and walks away to find Brad and Frank still hiding behind the building. TITAN Guys, please tell me you got that last bit. BRAD HELMS Huh? TITAN You're kidding me. I give you my sexiest moves and you mean to tell me it was for nothing? BRAD HELMS We were afraid something might hit us. TITAN Looks like I've given the story of the century to the wrong man. He thinks about this for a moment, then it hits him. 103. TITAN Wait. What about that other reporter. Blond. Not so lumpy on the topper half, but killer legs. BRAD HELMS Roxanne. You want Roxanne. She's a much better reporter than I am. You want her. TITAN Where can I find her. FRANK We're actually not supposed to give out that sort of information. BRAD HELMS 1314 Mockingbird Lane. I believe she lives in a penthouse. TITAN You've been very helpful. He tosses Brad over his shoulder like a discarded ice cream cone. In the faint distance we see him splash down in the middle of the Metro City river. INT. ABANDONED METRO CITY LIBRARY - DAY Master Mind, pacing anxiously as Plato and Da Vinci pack boxes. Obviously Master Mind is going on the lamb. MASTER MIND Hurry, we must be on our way as soon as possible. DA VINCI Master, why must we flee? MASTER MIND I told you, Titan is too powerful. If he's set on destroying us, there's precious little we could do about it. DA VINCI Where are we going? 104. MASTER MIND To another city, someplace with a shitload of superheroes to fight. We'll start over, we'll go back to doing what we do best. PLATO With our tails between our legs? The old Master Mind would never have let this comment slip by, but as we have seen, he's not the same man. MASTER MIND Plato, do you have a better plan?! Master Mind's cell phone rings. He turns in shame from his men and answers it. MASTER MIND (CONT'D) Hello...Roxanne? INT. ROXANNE'S APARTMENT Roxanne paces back and forth on the phone. ROXANNE What are you going to do about Tighten? INTERCUT between Master Mind and Roxanne on phone. MASTER MIND Right now I'm packing, later I'll have a snack on the train. ROXANNE You're running away? MASTER MIND In a word - yes. ROXANNE You created this monster... MASTER MIND I didn't create this - the god's of irony did and I am eating the crow I so richly deserve. ROXANNE There's no time for self pity. 105. MASTER MIND I'll make the time. Roxanne can't believe what she's hearing. MASTER MIND (CONT'D) You can leave with us. You'll be safe. ROXANNE I'm not going anywhere. MASTER MIND Will you listen to me, no one can stop him. ROXANNE You have to try. The city needs your help. MASTER MIND I'm afraid you have an inflated opinion of me. ROXANNE What the hell's happened to you? The Master Mind I knew would never have run from a fight even though he knew deep in his heart that he didn't have a chance in hell of winning it. It was your best quality. You need to be that man right now...I... MASTER MIND What? ROXANNE (heart felt) I believe in you. Master Mind is taken aback, in a good way. But he catches himself before the words swell his heart. MASTER MIND Sweet words, but that man is dead. Please, Roxanne, just come with me. ROXANNE No...I guess you are a coward after all. Suddenly, there's a loud crash. 106. Roxanne looks up to see a huge hunk of her ceiling has been completely ripped off. Titan is flying above, holding the debris as casually as if it were a paper plate at a barbecue. He looks down at her and smiles. TITAN Man, have I got a story for you. Master Mind can hears Titan's familiar laugh from his side of the line. MASTER MIND Roxanne? Roxanne? EXT. KINGPIN BOWLING - DAY Titan is standing in front of the bowling alley, trying to decide on an appropriate pose for the occasion. TITAN What pose would be best? The corny folded arms thing? He demonstrates, arching his chin proudly in the air. TITAN Or maybe on the hips, like this. It's the classic Superman pose, only not as masculine. TITAN No, makes me look like a flamer pirate. As Titan starts to fix his hair in the window, Frank pretends to fix the lens on his camera as he speaks to Roxanne. FRANK (whispering) Shouldn't we be making a run for it right about now? ROXANNE (whispering) The guy can outrun bullets. I don't think either one of us is in that kind of shape. TITAN She's right, Frank. 107. Frank looks up, stunned that Titan could have possibly heard him. TITAN Also got super hearing. I promise not to keep the both of you long, but you'll thank me when this is all over. Frank and Roxanne exchange helpless expressions. INT. ABANDONED METRO CITY LIBRARY - DAY Master Mind reverently stares up at the painted portrait of his father. MASTER MIND Dad, it's me... (he looks around to make sure no one can hear) ...Bubsy. I know we haven't talked in a while, and I'm sorry. It's been a little crazy trying to live up to a legacy. The painting's menacing stare seems to reach into his very soul. MASTER MIND Anyway...You raised me to be the worst that I could possibly be. And I've tried to live up to that as best as I could - even dropping out of dentistry school like you wanted me to. But I'm about to do something now that would really piss you off. I'm going to go against everything you ever taught me. I hope...I hope that maybe you'll look down at what I'm about to do as not so much a good deed, but more like the outright defiance of a hateful and ungrateful, son. If you could do that, then maybe - in your own little way - you could - for probably the first time - find a reason to be proud of me. He looks back up at the picture. Is it our imagination, or does the painting's stare suddenly seem even angrier? 108. MASTER MIND Well...either way, you're probably going to see me real soon. (calling over his shoulder) Men? Plato and Da Vinci suddenly stop what they're doing and look up at him. PLATO AND DA VINCI Yes Sir? MASTER MIND Stop packing. Our work is not finished here. PLATO AND DA VINCI YES SIR! TELEVISION A news report shows an aerial shot of Titan setting the giant ball down in the middle of a vacant city street. REPORTER We interrupt your regular afternoon programming to show you live footage of a potential dangerous situation in downtown Metro. The former hero knows as Titan is placing what appears to be a giant ball... INT. ABANDONED METRO CITY LIBRARY - CONTINUOUS Da Vinci stops in front of a television set, seeing the news report in progress. REPORTER Hold on...It appears our own Roxanne Ritchi is somehow at the scene. We now go to her with a live report. DA VINCI Sir, I think you should see this! CUT TO: 109. EXT. CITY STREET - DAY Roxanne is standing in front of a camera with a mike in her hand. ROXANNE I'm here with the cause of the destruction in Metro City. He has kidnapped me and a cameraman to chronicle what he refers to as the creation of a monument to his invincibility and overall "Asskickiness." He will use this giant concrete bowling ball to play the largest game of bowling ever using the buildings of downtown Metro City as his pins. Titan suddenly steps into the shot. TITAN And I'm going for the biggest strike ever. He leans into the camera. TITAN And you, Metro City, have a ringside seat as I cement my name in the anal of history. ROXANNE Annals. TITAN What? ROXANNE Nevermind. EXT. CITY STREET - MOMENTS LATER Titan holds up the massive bowling ball, lining up his shot. TITAN (in quiet professional bowler announcer voice) Like Tiger before him, a young savior has come to raise a sport from the ashes. Rookie Hal Stewart, a young man with a dream, realizing that dream here today, folks. (MORE) 110. TITAN(cont'd) One might click there heels and say "There's no place like home" upon finding themselves in such a fantasy. Well, Hal looks very much at home right were he is - with a ball in hand and glory in his sights. INT. METRO CITY LIBRARY - CONTINUOUS In the bowels of Master Mind's hideout, the HYDROGEN REACTOR glows and HUMS MENACINGLY. BACK TO SCENE Roxanne just stand helpless as Frank films away. ROXANNE Hal, I know everyone treated you like shit, but you don't have to do this. TITAN You're right. I don't HAVE to do anything. Isn't that cool? Titan lines up his shot. TITAN Here's one for the record books! Titan flies a few feet and rolls the ball down the main street. ROXANNE Her face is utter horror as she watches the inevitable destruction of Metro City. As the ball rolls - it demolishes everything in it's wake; cars, street lamps - windows shatter as the giant concrete sphere brushes along side buildings. TITAN He smiles in anticipation and uses "body English" to direct the ball. GIANT BOWLING BALL POV It's nearly halfway to its target. ROXANNE 111. She closes her eyes. Titan's smile fades. He looks around as if he hears something we don't. About two hundred feet in front of the first building a GIANT SPIDER WEB flies across the path of the ball, creating a defensive barrier. An enormous letter "M" is etched in the web's center. TITAN (CONT'D) What the...? The ball breaks through the web, but it's speed is greatly reduced. FRANK Look, what's that flying in the air? We suddenly see MASTER MIND FLYING OVER THE ROLLING BALL IN A JET PACK. He quickly pulls out his goo gun and starts laying down a path of sticky plasm to stop the destructive sphere's path. MASTER MIND C'mon, slow down Master Mind looks down to see the meter of the gun close to empty. MASTER MIND C'mon. The ball slows drastically then starts rolling to the side. It heads off an embankment and rolls harmlessly into a CANAL. MASTER MIND Gutterball! TITAN He's furious to say the least. TITAN YOU! Master Mind gives him a mocking grin. MASTER MIND Bowling? What other trailer park sports can you play? 112. TITAN You are becoming a real pain in my ass. I should have done this a long time ago. Titan lunges at his tormentor. Master Mind hits the BOOSTER on his jet pack and heads back toward the other side of the city with Titan in hot pursuit. MASTER MIND (CONT'D) (into walkie talkie) Plato, Da Vinci. Secure Roxanne, he's falling for it. ELSEWHERE A flustered Titan lands. He begins searching the city streets, but Master Mind is nowhere in sight. He turns upon hearing an EEKING sound to his left. Sitting on the ground is a CHIMPANZEE wearing a strange collar. It smiles at him. TITAN What the hell? From behind, Titan is immediately set upon by five more RADIO CONTROLLED APES. TITAN (CONT'D) GODAMNIT! The critters bite hop and hit Titan. As soon as he throws one off two more jump him. Titan breaks free and with his mighty breath blows them across the street into a fruit stand. With Titan out of their sight they begin to attack the fruit. MASTER MIND He's a block away frantically hitting his remote. MASTER MIND Shit! Stupid monkeys and their fruit. Titan flies away from the mad monkeys and lands to find Master Mind sitting on the ground wrapped in a long cape with only his head sticking out. 113. TITAN (CONT'D) No more games. Titan FIRES HIS LASER VISION AT MASTER MIND's CHEST. Master Mind pulls the cloak away to reveal a FIRE HYDRANT. Titan's EYE LASERS burn through the hydrant releasing a high pressure stream of water. Master Mind uses the last remote which dumps two tons of CEMENT mix into the truck. The crowd, police and news crews move in closer when Titan doesn't emerge. Master Mind drops his last remote and walks toward the truck cautiously. MASTER MIND Could it really be that easy-- - BOOM - The back of the truck explodes, throwing dust and concrete everywhere. When the dust clears we see and enraged Titan. MASTER MIND (CONT'D) Didn't think so. As the villain walks toward him, he pulls back his fist to give Master Mind the killing blow. TITAN If you don't mind, I'm going to punch trough your face now. Preparing himself for the end, Master Mind shuts his eyes as a SUDDEN GUST OF WIND BEGINS TO PICK UP. AS Titan goes to strike, a BLURRY FIGURE RUNS IN AND SNATCHES MASTER MIND OUT OF THE AWAY. Stunned, Master Mind begins to feel around his body as if to make sure everything's still in place. MASTER MIND I'm alive. He turns to see UBERMAN standing next to him. MASTER MIND Uberman? 114. The terrified bystanders start to notice the figure standing next to Master Mind. BYSTANDER 1 It's Uberman! BYSTANDER 2 Uberman's alive! BYSTANDER 3 We're saved! As the CROWD CHEERS, A confused Master Mind turns to Metro City's newly resurrected champion. MASTER MIND I thought. UBERMAN So did I. He puts a hand on Master Mind's shoulder. UBERMAN Thank you, old enemy. MASTER MIND For what? UBERMAN Showing me the error of my ways, Showing me I'm meant to be this city's savior, showing me that, while we can try, there is no running away from our true destiny. With that, UBERMAN IS STRICKEN BY A LASER BLAST, INSTANTLY TURNING HIM INTO A CHARRED HUMAN SKELETON. Master Mind turns to see Titan smiling with his STILL SMOKING EYES. TITAN Oh...Did I interrupt something? Master Mind turns to run, but, suddenly Titan is before him. TITAN Where you going, buddy? Titan grabs Master Mind by the collar and throws him across the street into a parked car. 115. TITAN (CONT'D) Welcome to Paintown. Population: you. Master Mind manages to stand on shaky legs. He seems in a daze, unable to move. Titan flies up in the air. TITAN (CONT'D) Time to finish this. With his fist front and center, Titan speeds toward Master Mind. He's like a human torpedo, coming in for the killing blow. Master Mind comes to his senses and puts up his hands. MASTER MIND WAIT!!! Titan screeches to a halt and stops just in front of him like an old Warner Bros cartoon. TITAN What? MASTER MIND Quick joke - What's the capital of Thailand? TITAN Huh - I don't know. MASTER MIND It's bang cock! In a sudden surge of strength, MASTER MIND PUNCHES TITAN IN THE GROIN. The once mighty man instantly drops to his knees, searching, with tears in his eyes, for the proper word to express the pain suddenly surging through his member. TITAN (CONT'D) Ow. Baffled, he looks up at Master Mind's hand and sees his gauntlet is now made ENTIRELY OUT OF COPPER. MASTER MIND So, I guess pennies are good for something. 116. He punches Titan in the face, knocking him out cold. Master Mind looks down on Titan with more than a little pride. Suddenly he hears something behind him. He spins to see the crowd making a strange noise - APPLAUSE. Roxanne comes up to him. The crowd starts to go wild and cheers for Master Mind. He's not sure what to make of it. ROXANNE Pretty strange, huh? MASTER MIND They're cheering for me. ROXANNE You saved them. You saved everybody. How's it feel? Master Mind looks at the smiles all around him. He begins to well up a little. MASTER MIND It's a...it's nice, you know? I usually don't get a lot of feedback. (whispering) But I also kind of caused all this. What happens when they find that out I was the cause of some of this? Roxanne looks at the cheering crowd, then back at Master Mind. ROXANNE What they don't know won't hurt them. MASTER MIND I guess that is all in the past. ROXANNE You're the hero. MASTER MIND I don't think I'd go that far...I mean I just...er... ROXANNE Master Mind? 117. MASTER MIND Yes? ROXANNE Stop talking. She kisses him. The crowd erupts in a cheer. TELEVISION The channel 7 he channel 7 logo zooms in followed by the title "Eye on Metro City." A picture of Master Mind smiling appears on the screen behind her. SAMANTHA SUMMERS Who's bad? Well, not Master Mind. It seems the former villain has done a career 180 after defeating Tighten and saving Metro City from certain enslavement. And here he is getting a full pardon by Metro City's Mayor, Steve Dent. Cut to ceremony on capital steps. The MAYOR is shaking Master Mind's metal gauntlet when it suddenly STARTS TO CRUSH HIS HAND. MAYOR Ahhh! Secret service men quickly start to draw their weapons and take aim at Master Mind. Realizing what's happening, he quickly lets the mayor's hand go and puts his arms in the air. MASTER MIND Sorry - Metal hand. Force of habit. He elbows the mayor. MASTER MIND (CONT'D) We're okay, right? Wincing, the mayor signals the men to put their guns down. WE CUT to video of Titan behind bars in a regular prison. 118. BRAD HELMS And what about Tighten? Is there a prison in existence that can hold this super powered menace? Well, the answer we found is no. A man in a white lab coat stands in front of Titan's cell just out of reach. PRISON SCIENTIST Of course normally he could break out of there anytime, but as you can see we've taken some special precautions. The news camera pans over see Titan in his cell wearing a copper JOCK STRAP with electrical cables hooked to it. Back to Samantha at the desk. BRAD HELMS What is a Hero? It seems never has that question needed to be asked more than it does tonight. We go to our very own Roxanne Ritchi, making her triumphant return to our news desk for the answer. Brad turns. The camera pans over to Roxanne who we now see has been sitting beside him. ROXANNE What is a hero? Well, there are many different kinds. There are those who hear a call, like the policeman or doctor, then there's the kind the public creates in their search for meaning and hope. Then, there are those who have the courage to change. DARK ALLEY - NIGHT A woman is being chased by two large thugs. They're gaining on her. She comes to a brick wall - a dead end. The thugs laugh. THUG #1 Hey, gimme that purse? 119. MASTER MIND (O.S) I don't think it would go with your outfit. The thugs turn around to see Master Mind, standing with his arms folded across his chest. THUG #2 It's Master Mind! Thug #1 draws a knife. THUG #1 So? It's not like he has any superpowers. Thug #1 puts his fingers to his mouth and whistles. Suddenly two more Thugs appear behind Master Mind. MASTER MIND I'm gonna give you a chance to surrender. THUG #1 Four against one. For a Master Mind, you're really bad at math. Master Mind throws a hand signal up in the air. Suddenly a giant robotic foot crashes down on the two men behind him. Thug #1 and Thug #2 drop their knives and raise their hands in the air. Master Mind looks up and waves. MASTER MIND Way to take out those two goons, guys! We see Da Vinci and Plato at the wheel of a gigantic robot. DA VINCI What two goons? The giant robot lifts its foot to check the bottom of it's sole. It KNOCKS OVER WATER TOWER in the process. The woman looks at Master Mind, horrified. 120. MASTER MIND (apologetically) Sorry, we're new at this. THE END

Online User Forum For technical questions regarding the Control System or the FTC SDK, please visit the FTC Technology forum: FTC Technology Forum Release Information Version 5.5 (20200824-090813) Version 5.5 requires Android Studio 4.0 or later. New features Adds support for calling custom Java classes from Blocks OpModes (fixes SkyStone issue #161). Classes must be in the org.firstinspires.ftc.teamcode package. Methods must be public static and have no more than 21 parameters. Parameters declared as OpMode, LinearOpMode, Telemetry, and HardwareMap are supported and the argument is provided automatically, regardless of the order of the parameters. On the block, the sockets for those parameters are automatically filled in. Parameters declared as char or java.lang.Character will accept any block that returns text and will only use the first character in the text. Parameters declared as boolean or java.lang.Boolean will accept any block that returns boolean. Parameters declared as byte, java.lang.Byte, short, java.lang.Short, int, java.lang.Integer, long, or java.lang.Long, will accept any block that returns a number and will round that value to the nearest whole number. Parameters declared as float, java.lang.Float, double, java.lang.Double will accept any block that returns a number. Adds telemetry API method for setting display format Classic Monospace HTML (certain tags only) Adds blocks support for switching cameras. Adds Blocks support for TensorFlow Object Detection with a custom model. Adds support for uploading a custom TensorFlow Object Detection model in the Manage page, which is especially useful for Blocks and OnBotJava users. Shows new Control Hub blink codes when the WiFi band is switched using the Control Hub's button (only possible on Control Hub OS 1.1.2) Adds new warnings which can be disabled in the Advanced RC Settings Mismatched app versions warning Unnecessary 2.4 GHz WiFi usage warning REV Hub is running outdated firmware (older than version 1.8.2) Adds support for Sony PS4 gamepad, and reworks how gamepads work on the Driver Station Removes preference which sets gamepad type based on driver position. Replaced with menu which allows specifying type for gamepads with unknown VID and PID Attempts to auto-detect gamepad type based on USB VID and PID If gamepad VID and PID is not known, use type specified by user for that VID and PID If gamepad VID and PID is not known AND the user has not specified a type for that VID and PID, an educated guess is made about how to map the gamepad Driver Station will now attempt to automatically recover from a gamepad disconnecting, and re-assign it to the position it was assigned to when it dropped If only one gamepad is assigned and it drops: it can be recovered If two gamepads are assigned, and have different VID/PID signatures, and only one drops: it will be recovered If two gamepads are assigned, and have different VID/PID signatures, and BOTH drop: both will be recovered If two gamepads are assigned, and have the same VID/PID signatures, and only one drops: it will be recovered If two gamepads are assigned, and have the same VID/PID signatures, and BOTH drop: neither will be recovered, because of the ambiguity of the gamepads when they re-appear on the USB bus. There is currently one known edge case: if there are two gamepads with the same VID/PID signature plugged in, but only one is assigned, and they BOTH drop, it's a 50-50 chance of which one will be chosen for automatic recovery to the assigned position: it is determined by whichever one is re-enumerated first by the USB bus controller. Adds landscape user interface to Driver Station New feature: practice timer with audio cues New feature (Control Hub only): wireless network connection strength indicator (0-5 bars) New feature (Control Hub only): tapping on the ping/channel display will switch to an alternate display showing radio RX dBm and link speed (tap again to switch back) The layout will NOT autorotate. You can switch the layout from the Driver Station's settings menu. Breaking changes Removes support for Android versions 4.4 through 5.1 (KitKat and Lollipop). The minSdkVersion is now 23. Removes the deprecated LinearOpMode methods waitOneFullHardwareCycle() and waitForNextHardwareCycle() Enhancements Handles RS485 address of Control Hub automatically The Control Hub is automatically given a reserved address Existing configuration files will continue to work All addresses in the range of 1-10 are still available for Expansion Hubs The Control Hub light will now normally be solid green, without blinking to indicate the address The Control Hub will not be shown on the Expansion Hub Address Change settings page Improves REV Hub firmware updater The user can now choose between all available firmware update files Version 1.8.2 of the REV Hub firmware is bundled into the Robot Controller app. Text was added to clarify that Expansion Hubs can only be updated via USB. Firmware update speed was reduced to improve reliability Allows REV Hub firmware to be updated directly from the Manage webpage Improves log viewer on Robot Controller Horizontal scrolling support (no longer word wrapped) Supports pinch-to-zoom Uses a monospaced font Error messages are highlighted New color scheme Attempts to force-stop a runaway/stuck OpMode without restarting the entire app Not all types of runaway conditions are stoppable, but if the user code attempts to talk to hardware during the runaway, the system should be able to capture it. Makes various tweaks to the Self Inspect screen Renames "OS version" entry to "Android version" Renames "WiFi Direct Name" to "WiFi Name" Adds Control Hub OS version, when viewing the report of a Control Hub Hides the airplane mode entry, when viewing the report of a Control Hub Removes check for ZTE Speed Channel Changer Shows firmware version for all Expansion and Control Hubs Reworks network settings portion of Manage page All network settings are now applied with a single click The WiFi Direct channel of phone-based Robot Controllers can now be changed from the Manage page WiFi channels are filtered by band (2.4 vs 5 GHz) and whether they overlap with other channels The current WiFi channel is pre-selected on phone-based Robot Controllers, and Control Hubs running OS 1.1.2 or later. On Control Hubs running OS 1.1.2 or later, you can choose to have the system automatically select a channel on the 5 GHz band Improves OnBotJava New light and dark themes replace the old themes (chaos, github, chrome,...) the new default theme is light and will be used when you first update to this version OnBotJava now has a tabbed editor Read-only offline mode Improves function of "exit" menu item on Robot Controller and Driver Station Now guaranteed to be fully stopped and unloaded from memory Shows a warning message if a LinearOpMode exists prematurely due to failure to monitor for the start condition Improves error message shown when the Driver Station and Robot Controller are incompatible with each other Driver Station OpMode Control Panel now disabled while a Restart Robot is in progress Disables advanced settings related to WiFi direct when the Robot Controller is a Control Hub. Tint phone battery icons on Driver Station when low/critical. Uses names "Control Hub Portal" and "Control Hub" (when appropriate) in new configuration files Improve I2C read performance Very large improvement on Control Hub; up to ~2x faster with small (e.g. 6 byte) reads Not as apparent on Expansion Hubs connected to a phone Update/refresh build infrastructure Update to 'androidx' support library from 'com.android.support:appcompat', which is end-of-life Update targetSdkVersion and compileSdkVersion to 28 Update Android Studio's Android plugin to latest Fix reported build timestamp in 'About' screen Add sample illustrating manual webcam use: ConceptWebcam Bug fixes Fixes SkyStone issue #248 Fixes SkyStone issue #232 and modifies bulk caching semantics to allow for cache-preserving MANUAL/AUTO transitions. Improves performance when REV 2M distance sensor is unplugged Improves readability of Toast messages on certain devices Allows a Driver Station to connect to a Robot Controller after another has disconnected Improves generation of fake serial numbers for UVC cameras which do not provide a real serial number Previously some devices would assign such cameras a serial of 0:0 and fail to open and start streaming Fixes ftc_app issue #638. Fixes a slew of bugs with the Vuforia camera monitor including: Fixes bug where preview could be displayed with a wonky aspect ratio Fixes bug where preview could be cut off in landscape Fixes bug where preview got totally messed up when rotating phone Fixes bug where crosshair could drift off target when using webcams Fixes issue in UVC driver on some devices (ftc_app 681) if streaming was started/stopped multiple times in a row Issue manifested as kernel panic on devices which do not have this kernel patch. On affected devices which do have the patch, the issue was manifest as simply a failure to start streaming. The Tech Team believes that the root cause of the issue is a bug in the Linux kernel XHCI driver. A workaround was implemented in the SDK UVC driver. Fixes bug in UVC driver where often half the frames from the camera would be dropped (e.g. only 15FPS delivered during a streaming session configured for 30FPS). Fixes issue where TensorFlow Object Detection would show results whose confidence was lower than the minimum confidence parameter. Fixes a potential exploitation issue of CVE-2019-11358 in OnBotJava Fixes changing the address of an Expansion Hub with additional Expansion Hubs connected to it Preserves the Control Hub's network connection when "Restart Robot" is selected Fixes issue where device scans would fail while the Robot was restarting Fix RenderScript usage Use androidx.renderscript variant: increased compatibility Use RenderScript in Java mode, not native: simplifies build Fixes webcam-frame-to-bitmap conversion problem: alpha channel wasn't being initialized, only R, G, & B Fixes possible arithmetic overflow in Deadline Fixes deadlock in Vuforia webcam support which could cause 5-second delays when stopping OpMode Version 5.4 (20200108-101156) Fixes SkyStone issue #88 Adds an inspection item that notes when a robot controller (Control Hub) is using the factory default password. Fixes SkyStone issue #61 Fixes SkyStone issue #142 Fixes ftc_app issue #417 by adding more current and voltage monitoring capabilities for REV Hubs. Fixes a crash sometimes caused by OnBotJava activity Improves OnBotJava autosave functionality ftc_app #738 Fixes system responsiveness issue when an Expansion Hub is disconnected Fixes issue where IMU initialization could prevent Op Modes from stopping Fixes issue where AndroidTextToSpeech.speak() would fail if it was called too early Adds telemetry.speak() methods and blocks, which cause the Driver Station (if also updated) to speak text Adds and improves Expansion Hub-related warnings Improves Expansion Hub low battery warning Displays the warning immediately after the hub reports it Specifies whether the condition is current or occurred temporarily during an OpMode run Displays which hubs reported low battery Displays warning when hub loses and regains power during an OpMode run Fixes the hub's LED pattern after this condition Displays warning when Expansion Hub is not responding to commands Specifies whether the condition is current or occurred temporarily during an OpMode run Clarifies warning when Expansion Hub is not present at startup Specifies that this condition requires a Robot Restart before the hub can be used. The hub light will now accurately reflect this state Improves logging and reduces log spam during these conditions Syncs the Control Hub time and timezone to a connected web browser programming the robot, if a Driver Station is not available. Adds bulk read functionality for REV Hubs A bulk caching mode must be set at the Hub level with LynxModule#setBulkCachingMode(). This applies to all relevant SDK hardware classes that reference that Hub. The following following Hub bulk caching modes are available: BulkCachingMode.OFF (default): All hardware calls operate as usual. Bulk data can read through LynxModule#getBulkData() and processed manually. BulkCachingMode.AUTO: Applicable hardware calls are served from a bulk read cache that is cleared/refreshed automatically to ensure identical commands don't hit the same cache. The cache can also be cleared manually with LynxModule#clearBulkCache(), although this is not recommended. (advanced users) BulkCachingMode.MANUAL: Same as BulkCachingMode.AUTO except the cache is never cleared automatically. To avoid getting stale data, the cache must be manually cleared at the beginning of each loop body or as the user deems appropriate. Removes PIDF Annotation values added in Rev 5.3 (to AndyMark, goBILDA and TETRIX motor configurations). The new motor types will still be available but their Default control behavior will revert back to Rev 5.2 Adds new ConceptMotorBulkRead sample Opmode to demonstrate and compare Motor Bulk-Read modes for reducing I/O latencies. Version 5.3 (20191004-112306) Fixes external USB/UVC webcam support Makes various bugfixes and improvements to Blocks page, including but not limited to: Many visual tweaks Browser zoom and window resize behave better Resizing the Java preview pane works better and more consistently across browsers The Java preview pane consistently gets scrollbars when needed The Java preview pane is hidden by default on phones Internet Explorer 11 should work Large dropdown lists display properly on lower res screens Disabled buttons are now visually identifiable as disabled A warning is shown if a user selects a TFOD sample, but their device is not compatible Warning messages in a Blocks op mode are now visible by default. Adds goBILDA 5201 and 5202 motors to Robot Configurator Adds PIDF Annotation values to AndyMark, goBILDA and TETRIX motor configurations. This has the effect of causing the RUN_USING_ENCODERS and RUN_TO_POSITION modes to use PIDF vs PID closed loop control on these motors. This should provide more responsive, yet stable, speed control. PIDF adds Feedforward control to the basic PID control loop. Feedforward is useful when controlling a motor's speed because it "anticipates" how much the control voltage must change to achieve a new speed set-point, rather than requiring the integrated error to change sufficiently. The PIDF values were chosen to provide responsive, yet stable, speed control on a lightly loaded motor. The more heavily a motor is loaded (drag or friction), the more noticable the PIDF improvement will be. Fixes startup crash on Android 10 Fixes ftc_app issue #712 (thanks to FROGbots-4634) Fixes ftc_app issue #542 Allows "A" and lowercase letters when naming device through RC and DS apps. Version 5.2 (20190905-083277) Fixes extra-wide margins on settings activities, and placement of the new configuration button Adds Skystone Vuforia image target data. Includes sample Skystone Vuforia Navigation op modes (Java). Includes sample Skystone Vuforia Navigation op modes (Blocks). Adds TensorFlow inference model (.tflite) for Skystone game elements. Includes sample Skystone TensorFlow op modes (Java). Includes sample Skystone TensorFlow op modes (Blocks). Removes older (season-specific) sample op modes. Includes 64-bit support (to comply with Google Play requirements). Protects against Stuck OpModes when a Restart Robot is requested. (Thanks to FROGbots-4634) (ftc_app issue #709) Blocks related changes: Fixes bug with blocks generated code when hardware device name is a java or javascript reserved word. Shows generated java code for blocks, even when hardware items are missing from the active configuration. Displays warning icon when outdated Vuforia and TensorFlow blocks are used (SkyStone issue #27) Version 5.1 (20190820-222104) Defines default PIDF parameters for the following motors: REV Core Hex Motor REV 20:1 HD Hex Motor REV 40:1 HD Hex Motor Adds back button when running on a device without a system back button (such as a Control Hub) Allows a REV Control Hub to update the firmware on a REV Expansion Hub via USB Fixes SkyStone issue #9 Fixes ftc_app issue #715 Prevents extra DS User clicks by filtering based on current state. Prevents incorrect DS UI state changes when receiving new OpMode list from RC Adds support for REV Color Sensor V3 Adds a manual-refresh DS Camera Stream for remotely viewing RC camera frames. To show the stream on the DS, initialize but do not run a stream-enabled opmode, select the Camera Stream option in the DS menu, and tap the image to refresh. This feature is automatically enabled when using Vuforia or TFOD—no additional RC configuration is required for typical use cases. To hide the stream, select the same menu item again. Note that gamepads are disabled and the selected opmode cannot be started while the stream is open as a safety precaution. To use custom streams, consult the API docs for CameraStreamServer#setSource and CameraStreamSource. Adds many Star Wars sounds to RobotController resources. Added SKYSTONE Sounds Chooser Sample Program. Switches out startup, connect chimes, and error/warning sounds for Star Wars sounds Updates OnBot Java to use a WebSocket for communication with the robot The OnBot Java page no longer has to do a full refresh when a user switches from editing one file to another Known issues: Camera Stream The Vuforia camera stream inherits the issues present in the phone preview (namely ftc_app issue #574). This problem does not affect the TFOD camera stream even though it receives frames from Vuforia. The orientation of the stream frames may not always match the phone preview. For now, these frames may be rotated manually via a custom CameraStreamSource if desired. OnBotJava Browser back button may not always work correctly It's possible for a build to be queued, but not started. The OnBot Java build console will display a warning if this occurs. A user might not realize they are editing a different file if the user inadvertently switches from one file to another since this switch is now seamless. The name of the currently open file is displayed in the browser tab. Version 5.0 (built on 19.06.14) Support for the REV Robotics Control Hub. Adds a Java preview pane to the Blocks editor. Adds a new offline export feature to the Blocks editor. Display wifi channel in Network circle on Driver Station. Adds calibration for Logitech C270 Updates build tooling and target SDK. Compliance with Google's permissions infrastructure (Required after build tooling update). Keep Alives to mitigate the Motorola wifi scanning problem. Telemetry substitute no longer necessary. Improves Vuforia error reporting. Fixes ftctechnh/ftc_app issues 621, 713. Miscellaneous bug fixes and improvements. Version 4.3 (built on 18.10.31) Includes missing TensorFlow-related libraries and files. Version 4.2 (built on 18.10.30) Includes fix to avoid deadlock situation with WatchdogMonitor which could result in USB communication errors. Comm error appeared to require that user disconnect USB cable and restart the Robot Controller app to recover. robotControllerLog.txt would have error messages that included the words "E RobotCore: lynx xmit lock: #### abandoning lock:" Includes fix to correctly list the parent module address for a REV Robotics Expansion Hub in a configuration (.xml) file. Bug in versions 4.0 and 4.1 would incorrect list the address module for a parent REV Robotics device as "1". If the parent module had a higher address value than the daisy-chained module, then this bug would prevent the Robot Controller from communicating with the downstream Expansion Hub. Added requirement for ACCESS_COARSE_LOCATION to allow a Driver Station running Android Oreo to scan for Wi-Fi Direct devices. Added google() repo to build.gradle because aapt2 must be downloaded from the google() repository beginning with version 3.2 of the Android Gradle Plugin. Important Note: Android Studio users will need to be connected to the Internet the first time build the ftc_app project. Internet connectivity is required for the first build so the appropriate files can be downloaded from the Google repository. Users should not need to be connected to the Internet for subsequent builds. This should also fix buid issue where Android Studio would complain that it "Could not find com.android.tools.lint:lint-gradle:26.1.4" (or similar). Added support for REV Spark Mini motor controller as part of the configuration menu for a servo/PWM port on the REV Expansion Hub. Provide examples for playing audio files in an Op Mode. Block Development Tool Changes Includes a fix for a problem with the Velocity blocks that were reported in the FTC Technology forum (Blocks Programming subforum). Change the "Save completed successfully." message to a white color so it will contrast with a green background. Fixed the "Download image" feature so it will work if there are text blocks in the op mode. Introduce support for Google's TensorFlow Lite technology for object detetion for 2018-2019 game. TensorFlow lite can recognize Gold Mineral and Silver Mineral from 2018-2019 game. Example Java and Block op modes are included to show how to determine the relative position of the gold block (left, center, right). Version 4.1 (released on 18.09.24) Changes include: Fix to prevent crash when deprecated configuration annotations are used. Change to allow FTC Robot Controller APK to be auto-updated using FIRST Global Control Hub update scripts. Removed samples for non supported / non legal hardware. Improvements to Telemetry.addData block with "text" socket. Updated Blocks sample op mode list to include Rover Ruckus Vuforia example. Update SDK library version number. Version 4.0 (released on 18.09.12) Changes include: Initial support for UVC compatible cameras If UVC camera has a unique serial number, RC will detect and enumerate by serial number. If UVC camera lacks a unique serial number, RC will only support one camera of that type connected. Calibration settings for a few cameras are included (see TeamCode/src/main/res/xml/teamwebcamcalibrations.xml for details). User can upload calibration files from Program and Manage web interface. UVC cameras seem to draw a fair amount of electrical current from the USB bus. This does not appear to present any problems for the REV Robotics Control Hub. This does seem to create stability problems when using some cameras with an Android phone-based Robot Controller. FTC Tech Team is investigating options to mitigate this issue with the phone-based Robot Controllers. Updated sample Vuforia Navigation and VuMark Op Modes to demonstrate how to use an internal phone-based camera and an external UVC webcam. Support for improved motor control. REV Robotics Expansion Hub firmware 1.8 and greater will support a feed forward mechanism for closed loop motor control. FTC SDK has been modified to support PIDF coefficients (proportional, integral, derivative, and feed forward). FTC Blocks development tool modified to include PIDF programming blocks. Deprecated older PID-related methods and variables. REV's 1.8.x PIDF-related changes provide a more linear and accurate way to control a motor. Wireless Added 5GHz support for wireless channel changing for those devices that support it. Tested with Moto G5 and E4 phones. Also tested with other (currently non-approved) phones such as Samsung Galaxy S8. Improved Expansion Hub firmware update support in Robot Controller app Changes to make the system more robust during the firmware update process (when performed through Robot Controller app). User no longer has to disconnect a downstream daisy-chained Expansion Hub when updating an Expansion Hub's firmware. If user is updating an Expansion Hub's firmware through a USB connection, he/she does not have to disconnect RS485 connection to other Expansion Hubs. The user still must use a USB connection to update an Expansion Hub's firmware. The user cannot update the Expansion Hub firmware for a downstream device that is daisy chained through an RS485 connection. If an Expansion Hub accidentally gets "bricked" the Robot Controller app is now more likely to recognize the Hub when it scans the USB bus. Robot Controller app should be able to detect an Expansion Hub, even if it accidentally was bricked in a previous update attempt. Robot Controller app should be able to install the firmware onto the Hub, even if if accidentally was bricked in a previous update attempt. Resiliency FTC software can detect and enable an FTDI reset feature that is available with REV Robotics v1.8 Expansion Hub firmware and greater. When enabled, the Expansion Hub can detect if it hasn't communicated with the Robot Controller over the FTDI (USB) connection. If the Hub hasn't heard from the Robot Controller in a while, it will reset the FTDI connection. This action helps system recover from some ESD-induced disruptions. Various fixes to improve reliability of FTC software. Blocks Fixed errors with string and list indices in blocks export to java. Support for USB connected UVC webcams. Refactored optimized Blocks Vuforia code to support Rover Ruckus image targets. Added programming blocks to support PIDF (proportional, integral, derivative and feed forward) motor control. Added formatting options (under Telemetry and Miscellaneous categories) so user can set how many decimal places to display a numerical value. Support to play audio files (which are uploaded through Blocks web interface) on Driver Station in addition to the Robot Controller. Fixed bug with Download Image of Blocks feature. Support for REV Robotics Blinkin LED Controller. Support for REV Robotics 2m Distance Sensor. Added support for a REV Touch Sensor (no longer have to configure as a generic digital device). Added blocks for DcMotorEx methods. These are enhanced methods that you can use when supported by the motor controller hardware. The REV Robotics Expansion Hub supports these enhanced methods. Enhanced methods include methods to get/set motor velocity (in encoder pulses per second), get/set PIDF coefficients, etc.. Modest Improvements in Logging Decrease frequency of battery checker voltage statements. Removed non-FTC related log statements (wherever possible). Introduced a "Match Logging" feature. Under "Settings" a user can enable/disable this feature (it's disabled by default). If enabled, user provides a "Match Number" through the Driver Station user interface (top of the screen). The Match Number is used to create a log file specifically with log statements from that particular Op Mode run. Match log files are stored in /sdcard/FIRST/matlogs on the Robot Controller. Once an op mode run is complete, the Match Number is cleared. This is a convenient way to create a separate match log with statements only related to a specific op mode run. New Devices Support for REV Robotics Blinkin LED Controller. Support for REV Robotics 2m Distance Sensor. Added configuration option for REV 20:1 HD Hex Motor. Added support for a REV Touch Sensor (no longer have to configure as a generic digital device). Miscellaneous Fixed some errors in the definitions for acceleration and velocity in our javadoc documentation. Added ability to play audio files on Driver Station When user is configuring an Expansion Hub, the LED on the Expansion Hub will change blink pattern (purple-cyan) to indicate which Hub is currently being configured. Renamed I2cSensorType to I2cDeviceType. Added an external sample Op Mode that demonstrates localization using 2018-2019 (Rover Ruckus presented by QualComm) Vuforia targets. Added an external sample Op Mode that demonstrates how to use the REV Robotics 2m Laser Distance Sensor. Added an external sample Op Mode that demonstrates how to use the REV Robotics Blinkin LED Controller. Re-categorized external Java sample Op Modes to "TeleOp" instead of "Autonomous". Known issues: Initial support for UVC compatible cameras UVC cameras seem to draw significant amount of current from the USB bus. This does not appear to present any problems for the REV Robotics Control Hub. This does seem to create stability problems when using some cameras with an Android phone-based Robot Controller. FTC Tech Team is investigating options to mitigate this issue with the phone-based Robot Controllers. There might be a possible deadlock which causes the RC to become unresponsive when using a UVC webcam with a Nougat Android Robot Controller. Wireless When user selects a wireless channel, this channel does not necessarily persist if the phone is power cycled. Tech Team is hoping to eventually address this issue in a future release. Issue has been present since apps were introduced (i.e., it is not new with the v4.0 release). Wireless channel is not currently displayed for WiFi Direct connections. Miscellaneous The blink indication feature that shows which Expansion Hub is currently being configured does not work for a newly created configuration file. User has to first save a newly created configuration file and then close and re-edit the file in order for blink indicator to work. Version 3.6 (built on 17.12.18) Changes include: Blocks Changes Uses updated Google Blockly software to allow users to edit their op modes on Apple iOS devices (including iPad and iPhone). Improvement in Blocks tool to handle corrupt op mode files. Autonomous op modes should no longer get switched back to tele-op after re-opening them to be edited. The system can now detect type mismatches during runtime and alert the user with a message on the Driver Station. Updated javadoc documentation for setPower() method to reflect correct range of values (-1 to +1). Modified VuforiaLocalizerImpl to allow for user rendering of frames Added a user-overrideable onRenderFrame() method which gets called by the class's renderFrame() method. Version 3.5 (built on 17.10.30) Changes with version 3.5 include: Introduced a fix to prevent random op mode stops, which can occur after the Robot Controller app has been paused and then resumed (for example, when a user temporarily turns off the display of the Robot Controller phone, and then turns the screen back on). Introduced a fix to prevent random op mode stops, which were previously caused by random peer disconnect events on the Driver Station. Fixes issue where log files would be closed on pause of the RC or DS, but not re-opened upon resume. Fixes issue with battery handler (voltage) start/stop race. Fixes issue where Android Studio generated op modes would disappear from available list in certain situations. Fixes problem where OnBot Java would not build on REV Robotics Control Hub. Fixes problem where OnBot Java would not build if the date and time on the Robot Controller device was "rewound" (set to an earlier date/time). Improved error message on OnBot Java that occurs when renaming a file fails. Removed unneeded resources from android.jar binaries used by OnBot Java to reduce final size of Robot Controller app. Added MR_ANALOG_TOUCH_SENSOR block to Blocks Programming Tool. Version 3.4 (built on 17.09.06) Changes with version 3.4 include: Added telemetry.update() statement for BlankLinearOpMode template. Renamed sample Block op modes to be more consistent with Java samples. Added some additional sample Block op modes. Reworded OnBot Java readme slightly. Version 3.3 (built on 17.09.04) This version of the software includes improves for the FTC Blocks Programming Tool and the OnBot Java Programming Tool. Changes with verion 3.3 include: Android Studio ftc_app project has been updated to use Gradle Plugin 2.3.3. Android Studio ftc_app project is already using gradle 3.5 distribution. Robot Controller log has been renamed to /sdcard/RobotControllerLog.txt (note that this change was actually introduced w/ v3.2). Improvements in I2C reliability. Optimized I2C read for REV Expansion Hub, with v1.7 firmware or greater. Updated all external/samples (available through OnBot and in Android project folder). Vuforia Added support for VuMarks that will be used for the 2017-2018 season game. Blocks Update to latest Google Blockly release. Sample op modes can be selected as a template when creating new op mode. Fixed bug where the blocks would disappear temporarily when mouse button is held down. Added blocks for Range.clip and Range.scale. User can now disable/enable Block op modes. Fix to prevent occasional Blocks deadlock. OnBot Java Significant improvements with autocomplete function for OnBot Java editor. Sample op modes can be selected as a template when creating new op mode. Fixes and changes to complete hardware setup feature. Updated (and more useful) onBot welcome message. Known issues: Android Studio After updating to the new v3.3 Android Studio project folder, if you get error messages indicating "InvalidVirtualFileAccessException" then you might need to do a File->Invalidate Caches / Restart to clear the error. OnBot Java Sometimes when you push the build button to build all op modes, the RC returns an error message that the build failed. If you press the build button a second time, the build typically suceeds. Version 3.2 (built on 17.08.02) This version of the software introduces the "OnBot Java" Development Tool. Similar to the FTC Blocks Development Tool, the FTC OnBot Java Development Tool allows a user to create, edit and build op modes dynamically using only a Javascript-enabled web browser. The OnBot Java Development Tool is an integrated development environment (IDE) that is served up by the Robot Controller. Op modes are created and edited using a Javascript-enabled browser (Google Chromse is recommended). Op modes are saved on the Robot Controller Android device directly. The OnBot Java Development Tool provides a Java programming environment that does NOT need Android Studio. Changes with version 3.2 include: Enhanced web-based development tools Introduction of OnBot Java Development Tool. Web-based programming and management features are "always on" (user no longer needs to put Robot Controller into programming mode). Web-based management interface (where user can change Robot Controller name and also easily download Robot Controller log file). OnBot Java, Blocks and Management features available from web based interface. Blocks Programming Development Tool: Changed "LynxI2cColorRangeSensor" block to "REV Color/range sensor" block. Fixed tooltip for ColorSensor.isLightOn block. Added blocks for ColorSensor.getNormalizedColors and LynxI2cColorRangeSensor.getNormalizedColors. Added example op modes for digital touch sensor and REV Robotics Color Distance sensor. User selectable color themes. Includes many minor enhancements and fixes (too numerous to list). Known issues: Auto complete function is incomplete and does not support the following (for now): Access via this keyword Access via super keyword Members of the super cloass, not overridden by the class Any methods provided in the current class Inner classes Can't handle casted objects Any objects coming from an parenthetically enclosed expression Version 3.10 (built on 17.05.09) This version of the software provides support for the REV Robotics Expansion Hub. This version also includes improvements in the USB communication layer in an effort to enhance system resiliency. If you were using a 2.x version of the software previously, updating to version 3.1 requires that you also update your Driver Station software in addition to updating the Robot Controller software. Also note that in version 3.10 software, the setMaxSpeed and getMaxSpeed methods are no longer available (not deprecated, they have been removed from the SDK). Also note that the the new 3.x software incorporates motor profiles that a user can select as he/she configures the robot. Changes include: Blocks changes Added VuforiaTrackableDefaultListener.getPose and Vuforia.trackPose blocks. Added optimized blocks support for Vuforia extended tracking. Added atan2 block to the math category. Added useCompetitionFieldTargetLocations parameter to Vuforia.initialize block. If set to false, the target locations are placed at (0,0,0) with target orientation as specified in https://github.com/gearsincorg/FTCVuforiaDemo/blob/master/Robot_Navigation.java tutorial op mode. Incorporates additional improvements to USB comm layer to improve system resiliency (to recover from a greater number of communication disruptions). Additional Notes Regarding Version 3.00 (built on 17.04.13) In addition to the release changes listed below (see section labeled "Version 3.00 (built on 17.04.013)"), version 3.00 has the following important changes: Version 3.00 software uses a new version of the FTC Robocol (robot protocol). If you upgrade to v3.0 on the Robot Controller and/or Android Studio side, you must also upgrade the Driver Station software to match the new Robocol. Version 3.00 software removes the setMaxSpeed and getMaxSpeed methods from the DcMotor class. If you have an op mode that formerly used these methods, you will need to remove the references/calls to these methods. Instead, v3.0 provides the max speed information through the use of motor profiles that are selected by the user during robot configuration. Version 3.00 software currently does not have a mechanism to disable extra i2c sensors. We hope to re-introduce this function with a release in the near future. Version 3.00 (built on 17.04.13) *** Use this version of the software at YOUR OWN RISK!!! *** This software is being released as an "alpha" version. Use this version at your own risk! This pre-release software contains SIGNIFICANT changes, including changes to the Wi-Fi Direct pairing mechanism, rewrites of the I2C sensor classes, changes to the USB/FTDI layer, and the introduction of support for the REV Robotics Expansion Hub and the REV Robotics color-range-light sensor. These changes were implemented to improve the reliability and resiliency of the FTC control system. Please note, however, that version 3.00 is considered "alpha" code. This code is being released so that the FIRST community will have an opportunity to test the new REV Expansion Hub electronics module when it becomes available in May. The developers do not recommend using this code for critical applications (i.e., competition use). *** Use this version of the software at YOUR OWN RISK!!! *** Changes include: Major rework of sensor-related infrastructure. Includes rewriting sensor classes to implement synchronous I2C communication. Fix to reset Autonomous timer back to 30 seconds. Implementation of specific motor profiles for approved 12V motors (includes Tetrix, AndyMark, Matrix and REV models). Modest improvements to enhance Wi-Fi P2P pairing.

Channel change is enabled in the FTC Robot Controller app for Moto G 2nd and 3rd Gen phones. Users can now use annotations to register/disable their Op Modes. Changes in the Android SDK, JDK and build tool requirements (minsdk=19, java 1.7, build tools 23.0.3). Standardized units in analog input. Cleaned up code for existing analog sensor classes. setChannelMode and getChannelMode were REMOVED from the DcMotorController class. This is important - we no longer set the motor modes through the motor controller. setMode and getMode were added to the DcMotor class. ContinuousRotationServo class has been added to the FTC SDK. Range.clip() method has been overloaded so it can support this operation for int, short and byte integers. Some changes have been made (new methods added) on how a user can access items from the hardware map. Users can now set the zero power behavior for a DC motor so that the motor will brake or float when power is zero. Prototype Blockly Programming Mode has been added to FTC Robot Controller. Users can place the Robot Controller into this mode, and then use a device (such as a laptop) that has a Javascript enabled browser to write Blockly-based Op Modes directly onto the Robot Controller. Users can now configure the robot remotely through the FTC Driver Station app. Android Studio project supports Android Studio 2.1.x and compile SDK Version 23 (Marshmallow). Vuforia Computer Vision SDK integrated into FTC SDK. Users can use sample vision targets to get localization information on a standard FTC field. Project structure has been reorganized so that there is now a TeamCode package that users can use to place their local/custom Op Modes into this package. Inspection function has been integrated into the FTC Robot Controller and Driver Station Apps (Thanks Team HazMat… 9277 & 10650!). Audio cues have been incorporated into FTC SDK. Swap mechanism added to FTC Robot Controller configuration activity. For example, if you have two motor controllers on a robot, and you misidentified them in your configuration file, you can use the Swap button to swap the devices within the configuration file (so you do not have to manually re-enter in the configuration info for the two devices). Fix mechanism added to all user to replace an electronic module easily. For example, suppose a servo controller dies on your robot. You replace the broken module with a new module, which has a different serial number from the original servo controller. You can use the Fix button to automatically reconfigure your configuration file to use the serial number of the new module. Improvements made to fix resiliency and responsiveness of the system. For LinearOpMode the user now must for a telemetry.update() to update the telemetry data on the driver station. This update() mechanism ensures that the driver station gets the updated data properly and at the same time. The Auto Configure function of the Robot Controller is now template based. If there is a commonly used robot configuration, a template can be created so that the Auto Configure mechanism can be used to quickly configure a robot of this type. The logic to detect a runaway op mode (both in the LinearOpMode and OpMode types) and to abort the run, then auto recover has been improved/implemented. Fix has been incorporated so that Logitech F310 gamepad mappings will be correct for Marshmallow users. Release 16.07.08 For the ftc_app project, the gradle files have been modified to support Android Studio 2.1.x. Release 16.03.30 For the MIT App Inventor, the design blocks have new icons that better represent the function of each design component. Some changes were made to the shutdown logic to ensure the robust shutdown of some of our USB services. A change was made to LinearOpMode so as to allow a given instance to be executed more than once, which is required for the App Inventor. Javadoc improved/updated. Release 16.03.09 Changes made to make the FTC SDK synchronous (significant change!) waitOneFullHardwareCycle() and waitForNextHardwareCycle() are no longer needed and have been deprecated. runOpMode() (for a LinearOpMode) is now decoupled from the system's hardware read/write thread. loop() (for an OpMode) is now decoupled from the system's hardware read/write thread. Methods are synchronous. For example, if you call setMode(DcMotorController.RunMode.RESET_ENCODERS) for a motor, the encoder is guaranteed to be reset when the method call is complete. For legacy module (NXT compatible), user no longer has to toggle between read and write modes when reading from or writing to a legacy device. Changes made to enhance reliability/robustness during ESD event. Changes made to make code thread safe. Debug keystore added so that user-generated robot controller APKs will all use the same signed key (to avoid conflicts if a team has multiple developer laptops for example). Firmware version information for Modern Robotics modules are now logged. Changes made to improve USB comm reliability and robustness. Added support for voltage indicator for legacy (NXT-compatible) motor controllers. Changes made to provide auto stop capabilities for op modes. A LinearOpMode class will stop when the statements in runOpMode() are complete. User does not have to push the stop button on the driver station. If an op mode is stopped by the driver station, but there is a run away/uninterruptible thread persisting, the app will log an error message then force itself to crash to stop the runaway thread. Driver Station UI modified to display lowest measured voltage below current voltage (12V battery). Driver Station UI modified to have color background for current voltage (green=good, yellow=caution, red=danger, extremely low voltage). javadoc improved (edits and additional classes). Added app build time to About activity for driver station and robot controller apps. Display local IP addresses on Driver Station About activity. Added I2cDeviceSynchImpl. Added I2cDeviceSync interface. Added seconds() and milliseconds() to ElapsedTime for clarity. Added getCallbackCount() to I2cDevice. Added missing clearI2cPortActionFlag. Added code to create log messages while waiting for LinearOpMode shutdown. Fix so Wifi Direct Config activity will no longer launch multiple times. Added the ability to specify an alternate i2c address in software for the Modern Robotics gyro. Release 16.02.09 Improved battery checker feature so that voltage values get refreshed regularly (every 250 msec) on Driver Station (DS) user interface. Improved software so that Robot Controller (RC) is much more resilient and “self-healing” to USB disconnects: If user attempts to start/restart RC with one or more module missing, it will display a warning but still start up. When running an op mode, if one or more modules gets disconnected, the RC & DS will display warnings,and robot will keep on working in spite of the missing module(s). If a disconnected module gets physically reconnected the RC will auto detect the module and the user will regain control of the recently connected module. Warning messages are more helpful (identifies the type of module that’s missing plus its USB serial number). Code changes to fix the null gamepad reference when users try to reference the gamepads in the init() portion of their op mode. NXT light sensor output is now properly scaled. Note that teams might have to readjust their light threshold values in their op modes. On DS user interface, gamepad icon for a driver will disappear if the matching gamepad is disconnected or if that gamepad gets designated as a different driver. Robot Protocol (ROBOCOL) version number info is displayed in About screen on RC and DS apps. Incorporated a display filter on pairing screen to filter out devices that don’t use the “-“ format. This filter can be turned off to show all WiFi Direct devices. Updated text in License file. Fixed formatting error in OpticalDistanceSensor.toString(). Fixed issue on with a blank (“”) device name that would disrupt WiFi Direct Pairing. Made a change so that the WiFi info and battery info can be displayed more quickly on the DS upon connecting to RC. Improved javadoc generation. Modified code to make it easier to support language localization in the future. Release 16.01.04 Updated compileSdkVersion for apps Prevent Wifi from entering power saving mode removed unused import from driver station Corrrected "Dead zone" joystick code. LED.getDeviceName and .getConnectionInfo() return null apps check for ROBOCOL_VERSION mismatch Fix for Telemetry also has off-by-one errors in its data string sizing / short size limitations error User telemetry output is sorted. added formatting variants to DbgLog and RobotLog APIs code modified to allow for a long list of op mode names. changes to improve thread safety of RobocolDatagramSocket Fix for "missing hardware leaves robot controller disconnected from driver station" error fix for "fast tapping of Init/Start causes problems" (toast is now only instantiated on UI thread). added some log statements for thread life cycle. moved gamepad reset logic inside of initActiveOpMode() for robustness changes made to mitigate risk of race conditions on public methods. changes to try and flag when WiFi Direct name contains non-printable characters. fix to correct race condition between .run() and .close() in ReadWriteRunnableStandard. updated FTDI driver made ReadWriteRunnableStanard interface public. fixed off-by-one errors in Command constructor moved specific hardware implmentations into their own package. moved specific gamepad implemnatations to the hardware library. changed LICENSE file to new BSD version. fixed race condition when shutting down Modern Robotics USB devices. methods in the ColorSensor classes have been synchronized. corrected isBusy() status to reflect end of motion. corrected "back" button keycode. the notSupported() method of the GyroSensor class was changed to protected (it should not be public). Release 15.11.04.001 Added Support for Modern Robotics Gyro. The GyroSensor class now supports the MR Gyro Sensor. Users can access heading data (about Z axis) Users can also access raw gyro data (X, Y, & Z axes). Example MRGyroTest.java op mode included. Improved error messages More descriptive error messages for exceptions in user code. Updated DcMotor API Enable read mode on new address in setI2cAddress Fix so that driver station app resets the gamepads when switching op modes. USB-related code changes to make USB comm more responsive and to display more explicit error messages. Fix so that USB will recover properly if the USB bus returns garbage data. Fix USB initializtion race condition. Better error reporting during FTDI open. More explicit messages during USB failures. Fixed bug so that USB device is closed if event loop teardown method was not called. Fixed timer UI issue Fixed duplicate name UI bug (Legacy Module configuration). Fixed race condition in EventLoopManager. Fix to keep references stable when updating gamepad. For legacy Matrix motor/servo controllers removed necessity of appending "Motor" and "Servo" to controller names. Updated HT color sensor driver to use constants from ModernRoboticsUsbLegacyModule class. Updated MR color sensor driver to use constants from ModernRoboticsUsbDeviceInterfaceModule class. Correctly handle I2C Address change in all color sensors Updated/cleaned up op modes. Updated comments in LinearI2cAddressChange.java example op mode. Replaced the calls to "setChannelMode" with "setMode" (to match the new of the DcMotor method). Removed K9AutoTime.java op mode. Added MRGyroTest.java op mode (demonstrates how to use MR Gyro Sensor). Added MRRGBExample.java op mode (demonstrates how to use MR Color Sensor). Added HTRGBExample.java op mode (demonstrates how to use HT legacy color sensor). Added MatrixControllerDemo.java (demonstrates how to use legacy Matrix controller). Updated javadoc documentation. Updated release .apk files for Robot Controller and Driver Station apps. Release 15.10.06.002 Added support for Legacy Matrix 9.6V motor/servo controller. Cleaned up build.gradle file. Minor UI and bug fixes for driver station and robot controller apps. Throws error if Ultrasonic sensor (NXT) is not configured for legacy module port 4 or 5. Release 15.08.03.001 New user interfaces for FTC Driver Station and FTC Robot Controller apps. An init() method is added to the OpMode class. For this release, init() is triggered right before the start() method. Eventually, the init() method will be triggered when the user presses an "INIT" button on driver station. The init() and loop() methods are now required (i.e., need to be overridden in the user's op mode). The start() and stop() methods are optional. A new LinearOpMode class is introduced. Teams can use the LinearOpMode mode to create a linear (not event driven) program model. Teams can use blocking statements like Thread.sleep() within a linear op mode. The API for the Legacy Module and Core Device Interface Module have been updated. Support for encoders with the Legacy Module is now working. The hardware loop has been updated for better performance.

We track the tremendous work done across the Consortium through homogeneous work-spaces in Github which enables better monitoring and management. We are in the middle of a period where we are chartering numerous working groups which demonstrate the rapid degree of change for the Web platform: After 4 years, we are nearly ready to publish a Payment Request API Proposed Recommendation and we need to soon charter follow-on work. In the last year we chartered the Web Payment Security Interest Group. In the last year we chartered the Web Media Working Group with 7 specifications for next generation Media support on the Web. We have Accessibility Guidelines under W3C Member review which includes Silver, a new approach. We have just launched the Decentralized Identifier Working Group which has tremendous potential because Decentralized Identifier (DID) is an identifier that is globally unique, resolveable with high availability, and cryptographically verifiable. We have Privacy IG (PING) under W3C Member review which strengthens our focus on the tradeoff between privacy and function. We have a new CSS charter under W3C Member review which maps the group's work for the next three years. In this period, W3C and the WHATWG have succesfully completed the negotiation of a Memorandum of Understanding rooted in the mutual belief that that having two distinct specifications claiming to be normative is generally harmful for the Web community. The MOU, signed last May, describes how the two organizations are to collaborate on the development of a single authoritative version of the HTML and DOM specifications. W3C subsequently rechartered the HTML Working Group to assist the W3C community in raising issues and proposing solutions for the HTML and DOM specifications, and for the production of W3C Recommendations from WHATWG Review Drafts. As the Web evolves continuously, some groups are looking for ways for specifications to do so as well. So-called "evergreen recommendations" or "living standards" aim to track continuous development (and maintenance) of features, on a feature-by-feature basis, while getting review and patent commitments. We see the maturation and further development of an incredible number of new technologies coming to the Web. Continued progress in many areas demonstrates the vitality of the W3C and the Web community, as the rest of the report illustrates. Future Web Standards W3C has a variety of mechanisms for listening to what the community thinks could become good future Web standards. These include discussions with the Membership, discussions with other standards bodies, the activities of thousands of participants in over 300 community groups, and W3C Workshops. There are lots of good ideas. The W3C strategy team has been identifying promising topics and invites public participation. Future, recent and under consideration Workshops include: Inclusive XR (5-6 November 2019, Seattle, WA, USA) to explore existing and future approaches on making Virtual and Augmented Reality experiences more inclusive, including to people with disabilities; W3C Workshop on Data Models for Transportation (12-13 September 2019, Palo Alto, CA, USA) W3C Workshop on Web Games (27-28 June 2019, Redmond, WA, USA), view report Second W3C Workshop on the Web of Things (3-5 June 2019, Munich, Germany) W3C Workshop on Web Standardization for Graph Data; Creating Bridges: RDF, Property Graph and SQL (4-6 March 2019, Berlin, Germany), view report Web & Machine Learning. The Strategy Funnel documents the staff's exploration of potential new work at various phases: Exploration and Investigation, Incubation and Evaluation, and eventually to the chartering of a new standards group. The Funnel view is a GitHub Project where new area are issues represented by “cards” which move through the columns, usually from left to right. Most cards start in Exploration and move towards Chartering, or move out of the funnel. Public input is welcome at any stage but particularly once Incubation has begun. This helps W3C identify work that is sufficiently incubated to warrant standardization, to review the ecosystem around the work and indicate interest in participating in its standardization, and then to draft a charter that reflects an appropriate scope. Ongoing feedback can speed up the overall standardization process. Since the previous highlights document, W3C has chartered a number of groups, and started discussion on many more: Newly Chartered or Rechartered Web Application Security WG (03-Apr) Web Payment Security IG (17-Apr) Patent and Standards IG (24-Apr) Web Applications WG (14-May) Web & Networks IG (16-May) Media WG (23-May) Media and Entertainment IG (06-Jun) HTML WG (06-Jun) Decentralized Identifier WG (05-Sep) Extended Privacy IG (PING) (30-Sep) Verifiable Claims WG (30-Sep) Service Workers WG (31-Dec) Dataset Exchange WG (31-Dec) Web of Things Working Group (31-Dec) Web Audio Working Group (31-Dec) Proposed charters / Advance Notice Accessibility Guidelines WG Privacy IG (PING) RDF Literal Direction WG Timed Text WG CSS WG Web Authentication WG Closed Internationalization Tag Set IG Meeting Industry Needs Web Payments All Web Payments specifications W3C's payments standards enable a streamlined checkout experience, enabling a consistent user experience across the Web with lower front end development costs for merchants. Users can store and reuse information and more quickly and accurately complete online transactions. The Web Payments Working Group has republished Payment Request API as a Candidate Recommendation, aiming to publish a Proposed Recommendation in the Fall 2019, and is discussing use cases and features for Payment Request after publication of the 1.0 Recommendation. Browser vendors have been finalizing implementation of features added in the past year (view the implementation report). As work continues on the Payment Handler API and its implementation (currently in Chrome and Edge Canary), one focus in 2019 is to increase adoption in other browsers. Recently, Mastercard demonstrated the use of Payment Request API to carry out EMVCo's Secure Remote Commerce (SRC) protocol whose payment method definition is being developed with active participation by Visa, Mastercard, American Express, and Discover. Payment method availability is a key factor in merchant considerations about adopting Payment Request API. The ability to get uniform adoption of a new payment method such as Secure Remote Commerce (SRC) also depends on the availability of the Payment Handler API in browsers, or of proprietary alternatives. Web Monetization, which the Web Payments Working Group will discuss again at its face-to-face meeting in September, can be used to enable micropayments as an alternative revenue stream to advertising. Since the beginning of 2019, Amazon, Brave Software, JCB, Certus Cybersecurity Solutions and Netflix have joined the Web Payments Working Group. In April, W3C launched the Web Payment Security Group to enable W3C, EMVCo, and the FIDO Alliance to collaborate on a vision for Web payment security and interoperability. Participants will define areas of collaboration and identify gaps between existing technical specifications in order to increase compatibility among different technologies, such as: How do SRC, FIDO, and Payment Request relate? The Payment Services Directive 2 (PSD2) regulations in Europe are scheduled to take effect in September 2019. What is the role of EMVCo, W3C, and FIDO technologies, and what is the current state of readiness for the deadline? How can we improve privacy on the Web at the same time as we meet industry requirements regarding user identity? Digital Publishing All Digital Publishing specifications, Publication milestones The Web is the universal publishing platform. Publishing is increasingly impacted by the Web, and the Web increasingly impacts Publishing. Topic of particular interest to Publishing@W3C include typography and layout, accessibility, usability, portability, distribution, archiving, offline access, print on demand, and reliable cross referencing. And the diverse publishing community represented in the groups consist of the traditional "trade" publishers, ebook reading system manufacturers, but also publishers of audio book, scholarly journals or educational materials, library scientists or browser developers. The Publishing Working Group currently concentrates on Audiobooks which lack a comprehensive standard, thus incurring extra costs and time to publish in this booming market. Active development is ongoing on the future standard: Publication Manifest Audiobook profile for Web Publications Lightweight Packaging Format The BD Comics Manga Community Group, the Synchronized Multimedia for Publications Community Group, the Publishing Community Group and a future group on archival, are companions to the working group where specific work is developed and incubated. The Publishing Community Group is a recently launched incubation channel for Publishing@W3C. The goal of the group is to propose, document, and prototype features broadly related to: publications on the Web reading modes and systems and the user experience of publications The EPUB 3 Community Group has successfully completed the revision of EPUB 3.2. The Publishing Business Group fosters ongoing participation by members of the publishing industry and the overall ecosystem in the development of Web infrastructure to better support the needs of the industry. The Business Group serves as an additional conduit to the Publishing Working Group and several Community Groups for feedback between the publishing ecosystem and W3C. The Publishing BG has played a vital role in fostering and advancing the adoption and continued development of EPUB 3. In particular the BG provided critical support to the update of EPUBCheck to validate EPUB content to the new EPUB 3.2 specification. This resulted in the development, in conjunction with the EPUB3 Community Group, of a new generation of EPUBCheck, i.e., EPUBCheck 4.2 production-ready release. Media and Entertainment All Media specifications The Media and Entertainment vertical tracks media-related topics and features that create immersive experiences for end users. HTML5 brought standard audio and video elements to the Web. Standardization activities since then have aimed at turning the Web into a professional platform fully suitable for the delivery of media content and associated materials, enabling missing features to stream video content on the Web such as adaptive streaming and content protection. Together with Microsoft, Comcast, Netflix and Google, W3C received an Technology & Engineering Emmy Award in April 2019 for standardization of a full TV experience on the Web. Current goals are to: Reinforce core media technologies: Creation of the Media Working Group, to develop media-related specifications incubated in the WICG (e.g. Media Capabilities, Picture-in-picture, Media Session) and maintain maintain/evolve Media Source Extensions (MSE) and Encrypted Media Extensions (EME). Improve support for Media Timed Events: data cues incubation. Enhance color support (HDR, wide gamut), in scope of the CSS WG and in the Color on the Web CG. Reduce fragmentation: Continue annual releases of a common and testable baseline media devices, in scope of the Web Media APIs CG and in collaboration with the CTA WAVE Project. Maintain the Road-map of Media Technologies for the Web which highlights Web technologies that can be used to build media applications and services, as well as known gaps to enable additional use cases. Create the future: Discuss perspectives for Media and Entertainment for the Web. Bring the power of GPUs to the Web (graphics, machine learning, heavy processing), under incubation in the GPU for the Web CG. Transition to a Working Group is under discussion. Determine next steps after the successful W3C Workshop on Web Games of June 2019. View the report. Timed Text The Timed Text Working Group develops and maintains formats used for the representation of text synchronized with other timed media, like audio and video, and notably works on TTML, profiles of TTML, and WebVTT. Recent progress includes: A robust WebVTT implementation report poises the specification for publication as a proposed recommendation. Discussions around re-chartering, notably to add a TTML Profile for Audio Description deliverable to the scope of the group, and clarify that rendering of captions within XR content is also in scope. Immersive Web Hardware that enables Virtual Reality (VR) and Augmented Reality (AR) applications are now broadly available to consumers, offering an immersive computing platform with both new opportunities and challenges. The ability to interact directly with immersive hardware is critical to ensuring that the web is well equipped to operate as a first-class citizen in this environment. The Immersive Web Working Group has been stabilizing the WebXR Device API while the companion Immersive Web Community Group incubates the next series of features identified as key for the future of the Immersive Web. W3C plans a workshop focused on the needs and benefits at the intersection of VR & Accessibility (Inclusive XR), on 5-6 November 2019 in Seattle, WA, USA, to explore existing and future approaches on making Virtual and Augmented Reality experiences more inclusive. Web & Telecommunications The Web is the Open Platform for Mobile. Telecommunication service providers and network equipment providers have long been critical actors in the deployment of Web technologies. As the Web platform matures, it brings richer and richer capabilities to extend existing services to new users and devices, and propose new and innovative services. Real-Time Communications (WebRTC) All Real-Time Communications specifications WebRTC has reshaped the whole communication landscape by making any connected device a potential communication end-point, bringing audio and video communications anywhere, on any network, vastly expanding the ability of operators to reach their customers. WebRTC serves as the corner-stone of many online communication and collaboration services. The WebRTC Working Group aims to bringing WebRTC 1.0 (and companion specification Media Capture and Streams) to Recommendation by the end of 2019. Intense efforts are focused on testing (supported by a dedicated hackathon at IETF 104) and interoperability. The group is considering pushing features that have not gotten enough traction to separate modules or to a later minor revision of the spec. Beyond WebRTC 1.0, the WebRTC Working Group will focus its efforts on WebRTC NV which the group has started documenting by identifying use cases. Web & Networks Recently launched, in the wake of the May 2018 Web5G workshop, the Web & Networks Interest Group is chaired by representatives from AT&T, China Mobile and Intel, with a goal to explore solutions for web applications to achieve better performance and resource allocation, both on the device and network. The group's first efforts are around use cases, privacy & security requirements and liaisons. Automotive All Automotive specifications To create a rich application ecosystem for vehicles and other devices allowed to connect to the vehicle, the W3C Automotive Working Group is delivering a service specification to expose all common vehicle signals (engine temperature, fuel/charge level, range, tire pressure, speed, etc.) The Vehicle Information Service Specification (VISS), which is a Candidate Recommendation, is seeing more implementations across the industry. It provides the access method to a common data model for all the vehicle signals –presently encapsulating a thousand or so different data elements– and will be growing to accommodate the advances in automotive such as autonomous and driver assist technologies and electrification. The group is already working on a successor to VISS, leveraging the underlying data model and the VIWI submission from Volkswagen, for a more robust means of accessing vehicle signals information and the same paradigm for other automotive needs including location-based services, media, notifications and caching content. The Automotive and Web Platform Business Group acts as an incubator for prospective standards work. One of its task forces is using W3C VISS in performing data sampling and off-boarding the information to the cloud. Access to the wealth of information that W3C's auto signals standard exposes is of interest to regulators, urban planners, insurance companies, auto manufacturers, fleet managers and owners, service providers and others. In addition to components needed for data sampling and edge computing, capturing user and owner consent, information collection methods and handling of data are in scope. The upcoming W3C Workshop on Data Models for Transportation (September 2019) is expected to focus on the need of additional ontologies around transportation space. Web of Things All Web of Things specifications W3C's Web of Things work is designed to bridge disparate technology stacks to allow devices to work together and achieve scale, thus enabling the potential of the Internet of Things by eliminating fragmentation and fostering interoperability. Thing descriptions expressed in JSON-LD cover the behavior, interaction affordances, data schema, security configuration, and protocol bindings. The Web of Things complements existing IoT ecosystems to reduce the cost and risk for suppliers and consumers of applications that create value by combining multiple devices and information services. There are many sectors that will benefit, e.g. smart homes, smart cities, smart industry, smart agriculture, smart healthcare and many more. The Web of Things Working Group is finishing the initial Web of Things standards, with support from the Web of Things Interest Group: Web of Things Architecture Thing Descriptions Strengthening the Core of the Web HTML The HTML Working Group was chartered early June to assist the W3C community in raising issues and proposing solutions for the HTML and DOM specifications, and to produce W3C Recommendations from WHATWG Review Drafts. A few days before, W3C and the WHATWG signed a Memorandum of Understanding outlining the agreement to collaborate on the development of a single version of the HTML and DOM specifications. Issues and proposed solutions for HTML and DOM done via the newly rechartered HTML Working Group in the WHATWG repositories The HTML Working Group is targetting November 2019 to bring HTML and DOM to Candidate Recommendations. CSS All CSS specifications CSS is a critical part of the Open Web Platform. The CSS Working Group gathers requirements from two large groups of CSS users: the publishing industry and application developers. Within W3C, those groups are exemplified by the Publishing groups and the Web Platform Working Group. The former requires things like better pagination support and advanced font handling, the latter needs intelligent (and fast!) scrolling and animations. What we know as CSS is actually a collection of almost a hundred specifications, referred to as ‘modules’. The current state of CSS is defined by a snapshot, updated once a year. The group also publishes an index defining every term defined by CSS specifications. Fonts All Fonts specifications The Web Fonts Working Group develops specifications that allow the interoperable deployment of downloadable fonts on the Web, with a focus on Progressive Font Enrichment as well as maintenance of WOFF Recommendations. Recent and ongoing work includes: Early API experiments by Adobe and Monotype have demonstrated the feasibility of a font enrichment API, where a server delivers a font with minimal glyph repertoire and the client can query the full repertoire and request additional subsets on-the-fly. In other experiments, the Brotli compression used in WOFF 2 was extended to support shared dictionaries and patch update. Metrics to quantify improvement are a current hot discussion topic. The group will meet at ATypi 2019 in Japan, to gather requirements from the international typography community. The group will first produce a report summarizing the strengths and weaknesses of each prototype solution by Q2 2020. SVG All SVG specifications SVG is an important and widely-used part of the Open Web Platform. The SVG Working Group focuses on aligning the SVG 2.0 specification with browser implementations, having split the specification into a currently-implemented 2.0 and a forward-looking 2.1. Current activity is on stabilization, increased integration with the Open Web Platform, and test coverage analysis. The Working Group was rechartered in March 2019. A new work item concerns native (non-Web-browser) uses of SVG as a non-interactive, vector graphics format. Audio The Web Audio Working Group was extended to finish its work on the Web Audio API, expecting to publish it as a Recommendation by year end. The specification enables synthesizing audio in the browser. Audio operations are performed with audio nodes, which are linked together to form a modular audio routing graph. Multiple sources — with different types of channel layout — are supported. This modular design provides the flexibility to create complex audio functions with dynamic effects. The first version of Web Audio API is now feature complete and is implemented in all modern browsers. Work has started on the next version, and new features are being incubated in the Audio Community Group. Performance Web Performance All Web Performance specifications There are currently 18 specifications in development in the Web Performance Working Group aiming to provide methods to observe and improve aspects of application performance of user agent features and APIs. The W3C team is looking at related work incubated in the W3C GPU for the Web (WebGPU) Community Group which is poised to transition to a W3C Working Group. A preliminary draft charter is available. WebAssembly All WebAssembly specifications WebAssembly improves Web performance and power by being a virtual machine and execution environment enabling loaded pages to run native (compiled) code. It is deployed in Firefox, Edge, Safari and Chrome. The specification will soon reach Candidate Recommendation. WebAssembly enables near-native performance, optimized load time, and perhaps most importantly, a compilation target for existing code bases. While it has a small number of native types, much of the performance increase relative to Javascript derives from its use of consistent typing. WebAssembly leverages decades of optimization for compiled languages and the byte code is optimized for compactness and streaming (the web page starts executing while the rest of the code downloads). Network and API access all occurs through accompanying Javascript libraries -- the security model is identical to that of Javascript. Requirements gathering and language development occur in the Community Group while the Working Group manages test development, community review and progression of specifications on the Recommendation Track. Testing Browser testing plays a critical role in the growth of the Web by: Improving the reliability of Web technology definitions; Improving the quality of implementations of these technologies by helping vendors to detect bugs in their products; Improving the data available to Web developers on known bugs and deficiencies of Web technologies by publishing results of these tests. Browser Testing and Tools The Browser Testing and Tools Working Group is developing WebDriver version 2, having published last year the W3C Recommendation of WebDriver. WebDriver acts as a remote control interface that enables introspection and control of user agents, provides a platform- and language-neutral wire protocol as a way for out-of-process programs to remotely instruct the behavior of Web, and emulates the actions of a real person using the browser. WebPlatform Tests The WebPlatform Tests project now provides a mechanism which allows to fully automate tests that previously needed to be run manually: TestDriver. TestDriver enables sending trusted key and mouse events, sending complex series of trusted pointer and key interactions for things like in-content drag-and-drop or pinch zoom, and even file upload. Since 2014 W3C began work on this coordinated open-source effort to build a cross-browser test suite for the Web Platform, which WHATWG, and all major browsers adopted. Web of Data All Data specifications There have been several great success stories around the standardization of data on the web over the past year. Verifiable Claims seems to have significant uptake. It is also significant that the Distributed Identifier WG charter has received numerous favorable reviews, and was just recently launched. JSON-LD has been a major success with the large deployment on Web sites via schema.org. JSON-LD 1.1 completed technical work, about to transition to CR More than 25% of websites today include schema.org data in JSON-LD The Web of Things description is in CR since May, making use of JSON-LD Verifiable Credentials data model is in CR since July, also making use of JSON-LD Continued strong interest in decentralized identifiers Engagement from the TAG with reframing core documents, such as Ethical Web Principles, to include data on the web within their scope Data is increasingly important for all organizations, especially with the rise of IoT and Big Data. W3C has a mature and extensive suite of standards relating to data that were developed over two decades of experience, with plans for further work on making it easier for developers to work with graph data and knowledge graphs. Linked Data is about the use of URIs as names for things, the ability to dereference these URIs to get further information and to include links to other data. There are ever-increasing sources of open Linked Data on the Web, as well as data services that are restricted to the suppliers and consumers of those services. The digital transformation of industry is seeking to exploit advanced digital technologies. This will facilitate businesses to integrate horizontally along the supply and value chains, and vertically from the factory floor to the office floor. W3C is seeking to make it easier to support enterprise-wide data management and governance, reflecting the strategic importance of data to modern businesses. Traditional approaches to data have focused on tabular databases (SQL/RDBMS), Comma Separated Value (CSV) files, and data embedded in PDF documents and spreadsheets. We're now in midst of a major shift to graph data with nodes and labeled directed links between them. Graph data is: Faster than using SQL and associated JOIN operations More favorable to integrating data from heterogeneous sources Better suited to situations where the data model is evolving In the wake of the recent W3C Workshop on Graph Data we are in the process of launching a Graph Standardization Business Group to provide a business perspective with use cases and requirements, to coordinate technical standards work and liaisons with external organizations. Web for All Security, Privacy, Identity All Security specifications, all Privacy specifications Authentication on the Web As the WebAuthn Level 1 W3C Recommendation published last March is seeing wide implementation and adoption of strong cryptographic authentication, work is proceeding on Level 2. The open standard Web API gives native authentication technology built into native platforms, browsers, operating systems (including mobile) and hardware, offering protection against hacking, credential theft, phishing attacks, thus aiming to end the era of passwords as a security construct. You may read more in our March press release. Privacy An increasing number of W3C specifications are benefitting from Privacy and Security review; there are security and privacy aspects to every specification. Early review is essential. Working with the TAG, the Privacy Interest Group has updated the Self-Review Questionnaire: Security and Privacy. Other recent work of the group includes public blogging further to the exploration of anti-patterns in standards and permission prompts. Security The Web Application Security Working Group adopted Feature Policy, aiming to allow developers to selectively enable, disable, or modify the behavior of some of these browser features and APIs within their application; and Fetch Metadata, aiming to provide servers with enough information to make a priori decisions about whether or not to service a request based on the way it was made, and the context in which it will be used. The Web Payment Security Interest Group, launched last April, convenes members from W3C, EMVCo, and the FIDO Alliance to discuss cooperative work to enhance the security and interoperability of Web payments (read more about payments). Internationalization (i18n) All Internationalization specifications, educational articles related to Internationalization, spec developers checklist Only a quarter or so current Web users use English online and that proportion will continue to decrease as the Web reaches more and more communities of limited English proficiency. If the Web is to live up to the "World Wide" portion of its name, and for the Web to truly work for stakeholders all around the world engaging with content in various languages, it must support the needs of worldwide users as they engage with content in the various languages. The growth of epublishing also brings requirements for new features and improved typography on the Web. It is important to ensure the needs of local communities are captured. The W3C Internationalization Initiative was set up to increase in-house resources dedicated to accelerating progress in making the World Wide Web "worldwide" by gathering user requirements, supporting developers, and education & outreach. For an overview of current projects see the i18n radar. W3C's Internationalization efforts progressed on a number of fronts recently: Requirements: New African and European language groups will work on the gap analysis, errata and layout requirements. Gap analysis: Japanese, Devanagari, Bengali, Tamil, Lao, Khmer, Javanese, and Ethiopic updated in the gap-analysis documents. Layout requirements document: notable progress tracked in the Southeast Asian Task Force while work continues on Chinese layout requirements. Developer support: Spec reviews: the i18n WG continues active review of specifications of the WHATWG and other W3C Working Groups. Short review checklist: easy way to begin a self-review to help spec developers understand what aspects of their spec are likely to need attention for internationalization, and points them to more detailed checklists for the relevant topics. It also helps those reviewing specs for i18n issues. Strings on the Web: Language and Direction Metadata lays out issues and discusses potential solutions for passing information about language and direction with strings in JSON or other data formats. The document was rewritten for clarity, and expanded. The group is collaborating with the JSON-LD and Web Publishing groups to develop a plan for updating RDF, JSON-LD and related specifications to handle metadata for base direction of text (bidi). User-friendly test format: a new format was developed for Internationalization Test Suite tests, which displays helpful information about how the test works. This particularly useful because those tests are pointed to by educational materials and gap-analysis documents. Web Platform Tests: a large number of tests in the i18n test suite have been ported to the WPT repository, including: css-counter-styles, css-ruby, css-syntax, css-test, css-text-decor, css-writing-modes, and css-pseudo. Education & outreach: (for all educational materials, see the HTML & CSS Authoring Techniques) Web Accessibility All Accessibility specifications, WAI resources The Web Accessibility Initiative supports W3C's Web for All mission. Recent achievements include: Education and training: Inaccessibility of CAPTCHA updated to bring our analysis and recommendations up to date with CAPTCHA practice today, concluding two years of extensive work and invaluable input from the public (read more on the W3C Blog Learn why your web content and applications should be accessible. The Education and Outreach Working Group has completed revision and updating of the Business Case for Digital Accessibility. Accessibility guidelines: The Accessibility Guidelines Working Group has continued to update WCAG Techniques and Understanding WCAG 2.1; and published a Candidate Recommendation of Accessibility Conformance Testing Rules Format 1.0 to improve inter-rater reliability when evaluating conformance of web content to WCAG An updated charter is being developed to host work on "Silver", the next generation accessibility guidelines (WCAG 2.2) There are accessibility aspects to most specifications. Check your work with the FAST checklist. Outreach to the world W3C Developer Relations To foster the excellent feedback loop between Web Standards development and Web developers, and to grow participation from that diverse community, recent W3C Developer Relations activities include: @w3cdevs tracks the enormous amount of work happening across W3C W3C Track during the Web Conference 2019 in San Francisco Tech videos: W3C published the 2019 Web Games Workshop videos The 16 September 2019 Developer Meetup in Fukuoka, Japan, is open to all and will combine a set of technical demos prepared by W3C groups, and a series of talks on a selected set of W3C technologies and projects W3C is involved with Mozilla, Google, Samsung, Microsoft and Bocoup in the organization of ViewSource 2019 in Amsterdam (read more on the W3C Blog) W3C Training In partnership with EdX, W3C's MOOC training program, W3Cx offers a complete "Front-End Web Developer" (FEWD) professional certificate program that consists of a suite of five courses on the foundational languages that power the Web: HTML5, CSS and JavaScript. We count nearly 900K students from all over the world. Translations Many Web users rely on translations of documents developed at W3C whose official language is English. W3C is extremely grateful to the continuous efforts of its community in ensuring our various deliverables in general, and in our specifications in particular, are made available in other languages, for free, ensuring their exposure to a much more diverse set of readers. Last Spring we developed a more robust system, a new listing of translations of W3C specifications and updated the instructions on how to contribute to our translation efforts. W3C Liaisons Liaisons and coordination with numerous organizations and Standards Development Organizations (SDOs) is crucial for W3C to: make sure standards are interoperable coordinate our respective agenda in Internet governance: W3C participates in ICANN, GIPO, IGF, the I* organizations (ICANN, IETF, ISOC, IAB). ensure at the government liaison level that our standards work is officially recognized when important to our membership so that products based on them (often done by our members) are part of procurement orders. W3C has ARO/PAS status with ISO. W3C participates in the EU MSP and Rolling Plan on Standardization ensure the global set of Web and Internet standards form a compatible stack of technologies, at the technical and policy level (patent regime, fragmentation, use in policy making) promote Standards adoption equally by the industry, the public sector, and the public at large Coralie Mercier, Editor, W3C Marketing & Communications $Id: Overview.html,v 1.60 2019/10/15 12:05:52 coralie Exp $ Copyright © 2019 W3C ® (MIT, ERCIM, Keio, Beihang) Usage policies apply.

SOYJUN / FTP Implement Based On UDPThe aim of this assignment is to have you do UDP socket client / server programming with a focus on two broad aspects : Setting up the exchange between the client and server in a secure way despite the lack of a formal connection (as in TCP) between the two, so that ‘outsider’ UDP datagrams (broadcast, multicast, unicast - fortuitously or maliciously) cannot intrude on the communication. Introducing application-layer protocol data-transmission reliability, flow control and congestion control in the client and server using TCP-like ARQ sliding window mechanisms. The second item above is much more of a challenge to implement than the first, though neither is particularly trivial. But they are not tightly interdependent; each can be worked on separately at first and then integrated together at a later stage. Apart from the material in Chapters 8, 14 & 22 (especially Sections 22.5 - 22.7), and the experience you gained from the preceding assignment, you will also need to refer to the following : ioctl function (Chapter 17). get_ifi_info function (Section 17.6, Chapter 17). This function will be used by the server code to discover its node’s network interfaces so that it can bind all its interface IP addresses (see Section 22.6). ‘Race’ conditions (Section 20.5, Chapter 20) You also need a thorough understanding of how the TCP protocol implements reliable data transfer, flow control and congestion control. Chapters 17- 24 of TCP/IP Illustrated, Volume 1 by W. Richard Stevens gives a good overview of TCP. Though somewhat dated for some things (it was published in 1994), it remains, overall, a good basic reference. Overview This assignment asks you to implement a primitive file transfer protocol for Unix platforms, based on UDP, and with TCP-like reliability added to the transfer operation using timeouts and sliding-window mechanisms, and implementing flow and congestion control. The server is a concurrent server which can handle multiple clients simultaneously. A client gives the server the name of a file. The server forks off a child which reads directly from the file and transfers the contents over to the client using UDP datagrams. The client prints out the file contents as they come in, in order, with nothing missing and with no duplication of content, directly on to stdout (via the receiver sliding window, of course, but with no other intermediate buffering). The file to be transferred can be of arbitrary length, but its contents are always straightforward ascii text. As an aside let me mention that assuming the file contents ascii is not as restrictive as it sounds. We can always pretend, for example, that binary files are base64 encoded (“ASCII armor”). A real file transfer protocol would, of course, have to worry about transferring files between heterogeneous platforms with different file structure conventions and semantics. The sender would first have to transform the file into a platform-independent, protocol-defined, format (using, say, ASN.1, or some such standard), and the receiver would have to transform the received file into its platform’s native file format. This kind of thing can be fairly time consuming, and is certainly very tedious, to implement, with little educational value - it is not part of this assignment. Arguments for the server You should provide the server with an input file server.in from which it reads the following information, in the order shown, one item per line : Well-known port number for server. Maximum sending sliding-window size (in datagram units). You will not be handing in your server.in file. We shall create our own when we come to test your code. So it is important that you stick strictly to the file name and content conventions specified above. The same applies to the client.in input file below. Arguments for the client The client is to be provided with an input file client.in from which it reads the following information, in the order shown, one item per line : IP address of server (not the hostname). Well-known port number of server. filename to be transferred. Receiving sliding-window size (in datagram units). Random generator seed value. Probability p of datagram loss. This should be a real number in the range [ 0.0 , 1.0 ] (value 0.0 means no loss occurs; value 1.0 means all datagrams all lost). The mean µ, in milliseconds, for an exponential distribution controlling the rate at which the client reads received datagram payloads from its receive buffer. Operation Server starts up and reads its arguments from file server.in. As we shall see, when a client communicates with the server, the server will want to know what IP address that client is using to identify the server (i.e. , the destination IP address in the incoming datagram). Normally, this can be done relatively straightforwardly using the IP_RECVDESTADDR socket option, and picking up the information using the ancillary data (‘control information’) capability of the recvmsg function. Unfortunately, Solaris 2.10 does not support the IP_RECVDESTADDR option (nor, incidentally, does it support the msg_flags option in msghdr - see p.390). This considerably complicates things. In the absence of IP_RECVDESTADDR, what the server has to do as part of its initialization phase is to bind each IP address it has (and, simultaneously, its well-known port number, which it has read in from server.in) to a separate UDP socket. The code in Section 22.6, which uses the get_ifi_info function, shows you how to do that. However, there are important differences between that code and the version you want to implement. The code of Section 22.6 binds the IP addresses and forks off a child for each address that is bound to. We do not want to do that. Instead you should have an array of socket descriptors. For each IP address, create a new socket and bind the address (and well-known port number) to the socket without forking off child processes. Creating child processes comes later, when clients arrive. The code of Section 22.6 also attempts to bind broadcast addresses. We do not want to do this. It binds a wildcard IP address, which we certainly do not want to do either. We should bind strictly only unicast addresses (including the loopback address). The get_ifi_info function (which the code in Section 22.6 uses) has to be modified so that it also gets the network masks for the IP addresses of the node, and adds these to the information stored in the linked list of ifi_info structures (see Figure 17.5, p.471) it produces. As you go binding each IP address to a distinct socket, it will be useful for later processing to build your own array of structures, where a structure element records the following information for each socket : sockfd IP address bound to the socket network mask for the IP address subnet address (obtained by doing a bit-wise and between the IP address and its network mask) Report, in a ReadMe file which you hand in with your code, on the modifications you had to introduce to ensure that only unicast addresses are bound, and on your implementation of the array of structures described above. You should print out on stdout, with an appropriate message and appropriately formatted in dotted decimal notation, the IP address, network mask, and subnet address for each socket in your array of structures (you do not need to print the sockfd). The server now uses select to monitor the sockets it has created for incoming datagrams. When it returns from select, it must use recvfrom or recvmsg to read the incoming datagram (see 6. below). When a client starts, it first reads its arguments from the file client.in. The client checks if the server host is ‘local’ to its (extended) Ethernet. If so, all its communication to the server is to occur as MSG_DONTROUTE (or SO_DONTROUTE socket option). It determines if the server host is ‘local’ as follows. The first thing the client should do is to use the modified get_ifi_info function to obtain all of its IP addresses and associated network masks. Print out on stdout, in dotted decimal notation and with an appropriate message, the IP addresses and network masks obtained. In the following, IPserver designates the IP address the client will use to identify the server, and IPclient designates the IP address the client will choose to identify itself. The client checks whether the server is on the same host. If so, it should use the loopback address 127.0.0.1 for the server (i.e. , IPserver = 127.0.0.1). IPclient should also be set to the loopback address. Otherwise it proceeds as follows: IPserver is set to the IP address for the server in the client.in file. Given IPserver and the (unicast) IP addresses and network masks for the client returned by get_ifi_info in the linked list of ifi_info structures, you should be able to figure out if the server node is ‘local’ or not. This will be discussed in class; but let me just remind you here that you should use ‘longest prefix matching’ where applicable. If there are multiple client addresses, and the server host is ‘local’, the client chooses an IP address for itself, IPclient, which matches up as ‘local’ according to your examination above. If the server host is not ‘local’, then IPclient can be chosen arbitrarily. Print out on stdout the results of your examination, as to whether the server host is ‘local’ or not, as well as the IPclient and IPserver addresses selected. Note that this manner of determining whether the server is local or not is somewhat clumsy and ‘over-engineered’, and, as such, should be viewed more in the nature of a pedagogical exercise. Ideally, we would like to look up the server IP address(es) in the routing table (see Section 18.3). This requires that a routing socket be created, for which we need superuser privilege. Alternatively, we might want to dump out the routing table, using the sysctl function for example (see Section 18.4), and examine it directly. Unfortunately, Solaris 2.10 does not support sysctl. Furthermore, note that there is a slight problem with the address 130.245.1.123/24 assigned to compserv3 (see rightmost column of file hosts, and note that this particular compserv3 address “overlaps” with the 130.245.1.x/28 addresses in that same column assigned to compserv1, compserv2 & comserv4). In particular, if the client is running on compserv3 and the server on any of the other three compservs, and if that server node is also being identified to the client by its /28 (rather than its /24) address, then the client will get a “false positive” when it tests as to whether the server node is local or not. In other words, the client will deem the server node to be local, whereas in fact it should not be considered local. Because of this, it is perhaps best simply not to use compserv3 to run the client (but it is o.k. to use it to run the server). Finally, using MSG_DONTROUTE where possible would seem to gain us efficiency, in as much as the kernel does not need to consult the routing table for every datagram sent. But, in fact, that is not so. Recall that one effect of connect with UDP sockets is that routing information is obtained by the kernel at the time the connect is issued. That information is cached and used for subsequent sends from the connected socket (see p.255). The client now creates a UDP socket and calls bind on IPclient, with 0 as the port number. This will cause the kernel to bind an ephemeral port to the socket. After the bind, use the getsockname function (Section 4.10) to obtain IPclient and the ephemeral port number that has been assigned to the socket, and print that information out on stdout, with an appropriate message and appropriately formatted. The client connects its socket to IPserver and the well-known port number of the server. After the connect, use the getpeername function (Section 4.10) to obtain IPserver and the well-known port number of the server, and print that information out on stdout, with an appropriate message and appropriately formatted. The client sends a datagram to the server giving the filename for the transfer. This send needs to be backed up by a timeout in case the datagram is lost. Note that the incoming datagram from the client will be delivered to the server at the socket to which the destination IP address that the datagram is carrying has been bound. Thus, the server can obtain that address (it is, of course, IPserver) and thereby achieve what IP_RECVDESTADDR would have given us had it been available. Furthermore, the server process can obtain the IP address (this will, of course, be IPclient) and ephemeral port number of the client through the recvfrom or recvmsg functions. The server forks off a child process to handle the client. The server parent process goes back to the select to listen for new clients. Hereafter, and unless otherwise stated, whenever we refer to the ‘server’, we mean the server child process handling the client’s file transfer, not the server parent process. Typically, the first thing the server child would be expected to do is to close all sockets it ‘inherits’ from its parent. However, this is not the case with us. The server child does indeed close the sockets it inherited, but not the socket on which the client request arrived. It leaves that socket open for now. Call this socket the ‘listening’ socket. The server (child) then checks if the client host is local to its (extended) Ethernet. If so, all its communication to the client is to occur as MSG_DONTROUTE (or SO_DONTROUTE socket option). If IPserver (obtained in 5. above) is the loopback address, then we are done. Otherwise, the server has to proceed with the following step. Use the array of structures you built in 1. above, together with the addresses IPserver and IPclient to determine if the client is ‘local’. Print out on stdout the results of your examination, as to whether the client host is ‘local’ or not. The server (child) creates a UDP socket to handle file transfer to the client. Call this socket the ‘connection’ socket. It binds the socket to IPserver, with port number 0 so that its kernel assigns an ephemeral port. After the bind, use the getsockname function (Section 4.10) to obtain IPserver and the ephemeral port number that has been assigned to the socket, and print that information out on stdout, with an appropriate message and appropriately formatted. The server then connects this ‘connection’ socket to the client’s IPclient and ephemeral port number. The server now sends the client a datagram, in which it passes it the ephemeral port number of its ‘connection’ socket as the data payload of the datagram. This datagram is sent using the ‘listening’ socket inherited from its parent, otherwise the client (whose socket is connected to the server’s ‘listening’ socket at the latter’s well-known port number) will reject it. This datagram must be backed up by the ARQ mechanism, and retransmitted in the event of loss. Note that if this datagram is indeed lost, the client might well time out and retransmit its original request message (the one carrying the file name). In this event, you must somehow ensure that the parent server does not mistake this retransmitted request for a new client coming in, and spawn off yet another child to handle it. How do you do that? It is potentially more involved than it might seem. I will be discussing this in class, as well as ‘race’ conditions that could potentially arise, depending on how you code the mechanisms I present. When the client receives the datagram carrying the ephemeral port number of the server’s ‘connection’ socket, it reconnects its socket to the server’s ‘connection’ socket, using IPserver and the ephemeral port number received in the datagram (see p.254). It now uses this reconnected socket to send the server an acknowledgment. Note that this implies that, in the event of the server timing out, it should retransmit two copies of its ‘ephemeral port number’ message, one on its ‘listening’ socket and the other on its ‘connection’ socket (why?). When the server receives the acknowledgment, it closes the ‘listening’ socket it inherited from its parent. The server can now commence the file transfer through its ‘connection’ socket. The net effect of all these binds and connects at server and client is that no ‘outsider’ UDP datagram (broadcast, multicast, unicast - fortuitously or maliciously) can now intrude on the communication between server and client. Starting with the first datagram sent out, the client behaves as follows. Whenever a datagram arrives, or an ACK is about to be sent out (or, indeed, the initial datagram to the server giving the filename for the transfer), the client uses some random number generator function random() (initialized by the client.in argument value seed) to decide with probability p (another client.in argument value) if the datagram or ACK should be discarded by way of simulating transmission loss across the network. (I will briefly discuss in class how you do this.) Adding reliability to UDP The mechanisms you are to implement are based on TCP Reno. These include : Reliable data transmission using ARQ sliding-windows, with Fast Retransmit. Flow control via receiver window advertisements. Congestion control that implements : SlowStart Congestion Avoidance (‘Additive-Increase/Multiplicative Decrease’ – AIMD) Fast Recovery (but without the window-inflation aspect of Fast Recovery) Only some, and by no means all, of the details for these are covered below. The rest will be presented in class, especially those concerning flow control and TCP Reno’s congestion control mechanisms in general : Slow Start, Congestion Avoidance, Fast Retransmit and Fast Recovery. Implement a timeout mechanism on the sender (server) side. This is available to you from Stevens, Section 22.5 . Note, however, that you will need to modify the basic driving mechanism of Figure 22.7 appropriately since the situation at the sender side is not a repetitive cycle of send-receive, but rather a straightforward progression of send-send-send-send- . . . . . . . . . . . Also, modify the RTT and RTO mechanisms of Section 22.5 as specified below. I will be discussing the details of these modifications and the reasons for them in class. Modify function rtt_stop (Fig. 22.13) so that it uses integer arithmetic rather than floating point. This will entail your also having to modify some of the variable and function parameter declarations throughout Section 22.5 from float to int, as appropriate. In the unprrt.h header file (Fig. 22.10) set : RTT_RXTMIN to 1000 msec. (1 sec. instead of the current value 3 sec.) RTT_RXTMAX to 3000 msec. (3 sec. instead of the current value 60 sec.) RTT_MAXNREXMT to 12 (instead of the current value 3) In function rtt_timeout (Fig. 22.14), after doubling the RTO in line 86, pass its value through the function rtt_minmax of Fig. 22.11 (somewhat along the lines of what is done in line 77 of rtt_stop, Fig. 22.13). Finally, note that with the modification to integer calculation of the smoothed RTT and its variation, and given the small RTT values you will experience on the cs / sbpub network, these calculations should probably now be done on a millisecond or even microsecond scale (rather than in seconds, as is the case with Stevens’ code). Otherwise, small measured RTTs could show up as 0 on a scale of seconds, yielding a negative result when we subtract the smoothed RTT from the measured RTT (line 72 of rtt_stop, Fig. 22.13). Report the details of your modifications to the code of Section 22.5 in the ReadMe file which you hand in with your code. We need to have a sender sliding window mechanism for the retransmission of lost datagrams; and a receiver sliding window in order to ensure correct sequencing of received file contents, and some measure of flow control. You should implement something based on TCP Reno’s mechanisms, with cumulative acknowledgments, receiver window advertisements, and a congestion control mechanism I will explain in detail in class. For a reference on TCP’s mechanisms generally, see W. Richard Stevens, TCP/IP Illustrated, Volume 1 , especially Sections 20.2 - 20.4 of Chapter 20 , and Sections 21.1 - 21.8 of Chapter 21 . Bear in mind that our sequence numbers should count datagrams, not bytes as in TCP. Remember that the sender and receiver window sizes have to be set according to the argument values in client.in and server.in, respectively. Whenever the sender window becomes full and so ‘locks’, the server should print out a message to that effect on stdout. Similarly, whenever the receiver window ‘locks’, the client should print out a message on stdout. Be aware of the potential for deadlock when the receiver window ‘locks’. This situation is handled by having the receiver process send a duplicate ACK which acts as a window update when its window opens again (see Figure 20.3 and the discussion about it in TCP/IP Illustrated). However, this is not enough, because ACKs are not backed up by a timeout mechanism in the event they are lost. So we will also need to implement a persist timer driving window probes in the sender process (see Sections 22.1 & 22.2 in Chapter 22 of TCP/IP Illustrated). Note that you do not have to worry about the Silly Window Syndrome discussed in Section 22.3 of TCP/IP Illustrated since the receiver process consumes ‘full sized’ 512-byte messages from the receiver buffer (see 3. below). Report on the details of the ARQ mechanism you implemented in the ReadMe file you hand in. Indeed, you should report on all the TCP mechanisms you implemented in the ReadMe file, both the ones discussed here, and the ones I will be discussing in class. Make your datagram payload a fixed 512 bytes, inclusive of the file transfer protocol header (which must, at the very least, carry: the sequence number of the datagram; ACKs; and advertised window notifications). The client reads the file contents in its receive buffer and prints them out on stdout using a separate thread. This thread sits in a repetitive loop till all the file contents have been printed out, doing the following. It samples from an exponential distribution with mean µ milliseconds (read from the client.in file), sleeps for that number of milliseconds; wakes up to read and print all in-order file contents available in the receive buffer at that point; samples again from the exponential distribution; sleeps; and so on. The formula -1 × µ × ln( random( ) ) , where ln is the natural logarithm, yields variates from an exponential distribution with mean µ, based on the uniformly-distributed variates over ( 0 , 1 ) returned by random(). Note that you will need to implement some sort of mutual exclusion/semaphore mechanism on the client side so that the thread that sleeps and wakes up to consume from the receive buffer is not updating the state variables of the buffer at the same time as the main thread reading from the socket and depositing into the buffer is doing the same. Furthermore, we need to ensure that the main thread does not effectively monopolize the semaphore (and thus lock out for prolonged periods of time) the sleeping thread when the latter wakes up. See the textbook, Section 26.7, ‘Mutexes: Mutual Exclusion’, pp.697-701. You might also find Section 26.8, ‘Condition Variables’, pp.701-705, useful. You will need to devise some way by which the sender can notify the receiver when it has sent the last datagram of the file transfer, without the receiver mistaking that EOF marker as part of the file contents. (Also, note that the last data segment could be a “short” segment of less than 512 bytes – your client needs to be able to handle this correctly somehow.) When the sender receives an ACK for the last datagram of the transfer, the (child) server terminates. The parent server has to take care of cleaning up zombie children. Note that if we want a clean closing, the client process cannot simply terminate when the receiver ACKs the last datagram. This ACK could be lost, which would leave the (child) server process ‘hanging’, timing out, and retransmitting the last datagram. TCP attempts to deal with this problem by means of the TIME_WAIT state. You should have your receiver process behave similarly, sticking around in something akin to a TIME_WAIT state in case in case it needs to retransmit the ACK. In the ReadMe file you hand in, report on how you dealt with the issues raised here: sender notifying receiver of the last datagram, clean closing, and so on. Output Some of the output required from your program has been described in the section Operation above. I expect you to provide further output – clear, well-structured, well-laid-out, concise but sufficient and helpful – in the client and server windows by means of which we can trace the correct evolution of your TCP’s behaviour in all its intricacies : information (e.g., sequence number) on datagrams and acks sent and dropped, window advertisements, datagram retransmissions (and why : dup acks or RTO); entering/exiting Slow Start and Congestion Avoidance, ssthresh and cwnd values; sender and receiver windows locking/unlocking; etc., etc. . . . . The onus is on you to convince us that the TCP mechanisms you implemented are working correctly. Too many students do not put sufficient thought, creative imagination, time or effort into this. It is not the TA’s nor my responsibility to sit staring at an essentially blank screen, trying to summon up our paranormal psychology skills to figure out if your TCP implementation is really working correctly in all its very intricate aspects, simply because the transferred file seems to be printing o.k. in the client window. Nor is it our responsibility to strain our eyes and our patience wading through a mountain of obscure, ill-structured, hyper-messy, debugging-style output because, for example, your effort-conserving concept of what is ‘suitable’ is to dump your debugging output on us, relevant, irrelevant, and everything in between.

bideeen / Building A Trading Strategy With Pythontrading strategy is a fixed plan to go long or short in markets, there are two common trading strategies: the momentum strategy and the reversion strategy. Firstly, the momentum strategy is also called divergence or trend trading. When you follow this strategy, you do so because you believe the movement of a quantity will continue in its current direction. Stated differently, you believe that stocks have momentum or upward or downward trends, that you can detect and exploit. Some examples of this strategy are the moving average crossover, the dual moving average crossover, and turtle trading: The moving average crossover is when the price of an asset moves from one side of a moving average to the other. This crossover represents a change in momentum and can be used as a point of making the decision to enter or exit the market. You’ll see an example of this strategy, which is the “hello world” of quantitative trading later on in this tutorial. The dual moving average crossover occurs when a short-term average crosses a long-term average. This signal is used to identify that momentum is shifting in the direction of the short-term average. A buy signal is generated when the short-term average crosses the long-term average and rises above it, while a sell signal is triggered by a short-term average crossing long-term average and falling below it. Turtle trading is a popular trend following strategy that was initially taught by Richard Dennis. The basic strategy is to buy futures on a 20-day high and sell on a 20-day low. Secondly, the reversion strategy, which is also known as convergence or cycle trading. This strategy departs from the belief that the movement of a quantity will eventually reverse. This might seem a little bit abstract, but will not be so anymore when you take the example. Take a look at the mean reversion strategy, where you actually believe that stocks return to their mean and that you can exploit when it deviates from that mean. That already sounds a whole lot more practical, right? Another example of this strategy, besides the mean reversion strategy, is the pairs trading mean-reversion, which is similar to the mean reversion strategy. Whereas the mean reversion strategy basically stated that stocks return to their mean, the pairs trading strategy extends this and states that if two stocks can be identified that have a relatively high correlation, the change in the difference in price between the two stocks can be used to signal trading events if one of the two moves out of correlation with the other. That means that if the correlation between two stocks has decreased, the stock with the higher price can be considered to be in a short position. It should be sold because the higher-priced stock will return to the mean. The lower-priced stock, on the other hand, will be in a long position because the price will rise as the correlation will return to normal. Besides these two most frequent strategies, there are also other ones that you might come across once in a while, such as the forecasting strategy, which attempts to predict the direction or value of a stock, in this case, in subsequent future time periods based on certain historical factors. There’s also the High-Frequency Trading (HFT) strategy, which exploits the sub-millisecond market microstructure. That’s all music for the future for now; Let’s focus on developing your first trading strategy for now! A Simple Trading Strategy As you read above, you’ll start with the “hello world” of quantitative trading: the moving average crossover. The strategy that you’ll be developing is simple: you create two separate Simple Moving Averages (SMA) of a time series with differing lookback periods, let’s say, 40 days and 100 days. If the short moving average exceeds the long moving average then you go long, if the long moving average exceeds the short moving average then you exit. Remember that when you go long, you think that the stock price will go up and will sell at a higher price in the future (= buy signal); When you go short, you sell your stock, expecting that you can buy it back at a lower price and realize a profit (= sell signal). This simple strategy might seem quite complex when you’re just starting out, but let’s take this step by step: First define your two different lookback periods: a short window and a long window. You set up two variables and assign one integer per variable. Make sure that the integer that you assign to the short window is shorter than the integer that you assign to the long window variable! Next, make an empty signals DataFrame, but do make sure to copy the index of your aapl data so that you can start calculating the daily buy or sell signal for your aapl data. Create a column in your empty signals DataFrame that is named signal and initialize it by setting the value for all rows in this column to 0.0. After the preparatory work, it’s time to create the set of short and long simple moving averages over the respective long and short time windows. Make use of the rolling() function to start your rolling window calculations: within the function, specify the window and the min_period, and set the center argument. In practice, this will result in a rolling() function to which you have passed either short_window or long_window, 1 as the minimum number of observations in the window that are required to have a value, and False, so that the labels are not set at the center of the window. Next, don’t forget to also chain the mean() function so that you calculate the rolling mean. After you have calculated the mean average of the short and long windows, you should create a signal when the short moving average crosses the long moving average, but only for the period greater than the shortest moving average window. In Python, this will result in a condition: signals['short_mavg'][short_window:] > signals['long_mavg'][short_window:]. Note that you add the [short_window:] to comply with the condition “only for the period greater than the shortest moving average window”. When the condition is true, the initialized value 0.0 in the signal column will be overwritten with 1.0. A “signal” is created! If the condition is false, the original value of 0.0 will be kept and no signal is generated. You use the NumPy where() function to set up this condition. Much the same like you read just now, the variable to which you assign this result is signals['signal'][short_window], because you only want to create signals for the period greater than the shortest moving average window! Lastly, you take the difference of the signals in order to generate actual trading orders. In other words, in this column of your signals DataFrame, you’ll be able to distinguish between long and short positions, whether you’re buying or selling stock.

Back and forth between myth and reality, our imaginations supplying what our workshops couldn't, we have engaged for a long time in this odd form of self-reproduction."[28] She traces the desire back to its Hellenistic roots and calls it the urge to "forge the Gods."[29] "Stephen Hawking believes AI could be mankind's last accomplishment".

nyaundid / EC2 AWS AND SHELLSEIS 665 Assignment 2: Linux & Git Overview This week we will focus on becoming familiar with launching a Linux server and working with some basic Linux and Git commands. We will use AWS to launch and host the Linux server. AWS might seem a little confusing at this point. Don’t worry, we will gain much more hands-on experience with AWS throughout the course. The goal is to get you comfortable working with the technology and not overwhelm you with all the details. Requirements You need to have a personal AWS account and GitHub account for this assignment. You should also read the Git Hands-on Guide and Linux Hands-on Guide before beginning this exercise. A word about grading One of the key DevOps practices we learn about in this class is the use of automation to increase the speed and repeatability of processes. Automation is utilized during the assignment grading process to review and assess your work. It’s important that you follow the instructions in each assignment and type in required files and resources with the proper names. All names are case sensitive, so a name like "Web1" is not the same as "web1". If you misspell a name, use the wrong case, or put a file in the wrong directory location you will lose points on your assignment. This is the easiest way to lose points, and also the most preventable. You should always double-check your work to make sure it accurately reflects the requirements specified in the assignment. You should always carefully review the content of your files before submitting your assignment. The assignment Let’s get started! Create GitHub repository The first step in the assignment is to setup a Git repository on GitHub. We will use a special solution called GitHub Classroom for this course which automates the process of setting up student assignment repositories. Here are the basic steps: Click on the following link to open Assignment 2 on the GitHub Classroom site: https://classroom.github.com/a/K4zcVmX- (Links to an external site.)Links to an external site. Click on the Accept this assignment button. GitHub Classroom will provide you with a URL (https) to access the assignment repository. Either copy this address to your clipboard or write it down somewhere. You will need to use this address to set up the repository on a Linux server. Example: https://github.com/UST-SEIS665/hw2-seis665-02-spring2019-<your github id>.git At this point your new repository to ready to use. The repository is currently empty. We will put some content in there soon! Launch Linux server The second step in the assignment is to launch a Linux server using AWS EC2. The server should have the following characteristics: Amazon Linux 2 AMI 64-bit (usually the first option listed) Located in a U.S. region (us-east-1) t2.micro instance type All default instance settings (storage, vpm, security group, etc.) I’ve shown you how to launch EC2 instances in class. You can review it on Canvas. Once you launch the new server, it may take a few minutes to provision. Log into server The next step is to log into the Linux server using a terminal program with a secure shell (SSH) support. You can use iTerm2 (Links to an external site.)Links to an external site. on a Mac and GitBash/PuTTY (Links to an external site.)Links to an external site. on a PC. You will need to have the private server key and the public IP address before attempting to log into the server. The server key is basically your password. If you lose it, you will need to terminate the existing instance and launch a new server. I recommend reusing the same key when launching new servers throughout the class. Note, I make this recommendation to make the learning process easier and not because it is a common security practice. I’ve shown you how to use a terminal application to log into the instance using a Windows desktop. Your personal computer or lab computer may be running a different OS version, but the process is still very similar. You can review the videos on the Canvas. Working with Linux If you’ve made it this far, congratulations! You’ve made it over the toughest hurdle. By the end of this course, I promise you will be able to launch and log into servers in your sleep. You should be looking at a login screen that looks something like this: Last login: Mon Mar 21 21:17:54 2016 from 174-20-199-194.mpls.qwest.net __| __|_ ) _| ( / Amazon Linux AMI ___|\___|___| https://aws.amazon.com/amazon-linux-ami/2015.09-release-notes/ 8 package(s) needed for security, out of 17 available Run "sudo yum update" to apply all updates. ec2-user@ip-172-31-15-26 ~]$ Your terminal cursor is sitting at the shell prompt, waiting for you to type in your first command. Remember the shell? It is a really cool program that lets you start other programs and manage services on the Linux system. The rest of this assignment will be spent working with the shell. Note, when you are asked to type in a command in the steps below, don’t type in the dollar-sign ($) character. This is just meant to represent the command prompt. The actual commands are represented by the characters to the right of the command prompt. Let’s start by asking the shell for some help. Type in: $ help The shell provides you with a list of commands you can run along with possible command options. Next, check out one of the pages in the built-in manual: $ man ls A man page will appear with information on how to use the ls command. This command is used to list the contents of file directories. Either space through the contents of the man page or hit q to exit. Most of the core Linux commands have man pages available. But honestly, some of these man pages are a bit hard to understand. Sometimes your best bet is to search on Google if you are trying to figure out how to use a specific command. When you initially log into Linux, the system places you in your home directory. Each user on the system has a separate home directory. Let’s see where your home directory is located: $ pwd The response should be /home/ec2-user. The pwd command is handy to remember if you ever forget what file directory you are currently located in. If you recall from the Linux Hands-on Guide, this directory is also your current working directory. Type in: $ cd / The cd command let’s you change to a new working directory on the server. In this case, we changed to the root (/) directory. This is the parent of all the other directories on the file system. Type in: $ ls The ls command lists the contents of the current directory. As you can see, root directory contains many other directories. You will become familiar with these directories over time. The ls command provides a very basic directory listing. You need to supply the command with some options if you want to see more detailed information. Type in: $ ls -la See how this command provides you with much more detailed information about the files and directories? You can use this detailed listing to see the owner, group, and access control list settings for each file or directory. Do you see any files listed? Remember, the first character in the access control list column denotes whether a listed item is a file or a directory. You probably see a couple files with names like .autofsck. How come you didn’t see this file when you typed in the lscommand without any options? (Try to run this command again to convince yourself.) Files names that start with a period are called hidden files. These files won’t appear on normal directory listings. Type in: $ cd /var Then, type in: $ ls You will see a directory listing for the /var directory. Next, type in: $ ls .. Huh. This directory listing looks the same as the earlier root directory listing. When you use two periods (..) in a directory path that means you are referring to the parent directory of the current directory. Just think of the two dots as meaning the directory above the current directory. Now, type in: $ cd ~ $ pwd Whoa. We’re back at our home directory again. The tilde character (~) is another one of those handy little directory path shortcuts. It always refers to our personal home directory. Keep in mind that since every user has their own home directory, the tilde shortcut will refer to a unique directory for each logged-in user. Most students are used to navigating a file system by clicking a mouse in nested graphical folders. When they start using a command-line to navigate a file system, they sometimes get confused and lose track of their current position in the file system. Remember, you can always use the pwd command to quickly figure out what directory you are currently working in. Let’s make some changes to the file system. We can easily make our own directories on the file system. Type: mkdir test Now type: ls Cool, there’s our new test directory. Let’s pretend we don’t like that directory name and delete it. Type: rmdir test Now it’s gone. How can you be sure? You should know how to check to see if the directory still exists at this point. Go ahead and check. Let’s create another directory. Type in: $ mkdir documents Next, change to the new directory: $ cd documents Did you notice that your command prompt displays the name of the current directory? Something like: [ec2-user@ip-172-31-15-26 documents]$. Pretty handy, huh? Okay, let’s create our first file in the documents directory. This is just an empty file for training purposes. Type in: $ touch paper.txt Check to see that the new file is in the directory. Now, go back to the previous directory. Remember the double dot shortcut? $ cd .. Okay, we don’t like our documents directory any more. Let’s blow it away. Type in: $ rmdir documents Uh oh. The shell didn’t like that command because the directory isn’t empty. Let’s change back into the documents directory. But this time don’t type in the full name of the directory. You can let shell auto-completion do the typing for you. Type in the first couple characters of the directory name and then hit the tab key: $ cd doc<tab> You should use the tab auto-completion feature often. It saves typing and makes working with the Linux file system much much easier. Tab is your friend. Now, remove the file by typing: $ rm paper.txt Did you try to use the tab key instead of typing in the whole file name? Check to make sure the file was deleted from the directory. Next, create a new file: $ touch file1 We like file1 so much that we want to make a backup copy. Type: $ cp file1 file1-backup Check to make sure the new backup copy was created. We don’t really like the name of that new file, so let’s rename it. Type: $ mv file1-backup backup Moving a file to the same directory and giving it a new name is basically the same thing as renaming it. We could have moved it to a different directory if we wanted. Let’s list all of the files in the current directory that start with the letter f: $ ls f* Using wildcard pattern matching in file commands is really useful if you want the command to impact or filter a group of files. Now, go up one directory to the parent directory (remember the double dot shortcut?) We tried to remove the documents directory earlier when it had files in it. Obviously that won’t work again. However, we can use a more powerful command to destroy the directory and vanquish its contents. Behold, the all powerful remove command: $ rm -fr documents Did you remember to use auto-completion when typing in documents? This command and set of options forcibly removes the directory and its contents. It’s a dangerous command wielded by the mightiest Linux wizards. Okay, maybe that’s a bit of an exaggeration. Just be careful with it. Check to make sure the documents directory is gone before proceeding. Let’s continue. Change to the directory /var and make a directory called test. Ugh. Permission denied. We created this darn Linux server and we paid for it. Shouldn’t we be able to do anything we want on it? You logged into the system as a user called ec2-user. While this user can create and manage files in its home directory, it cannot change files all across the system. At least it can’t as a normal user. The ec2-user is a member of the root group, so it can escalate its privileges to super-user status when necessary. Let’s try it: $ sudo mkdir test Check to make sure the directory exists now. Using sudo we can execute commands as a super-user. We can do anything we want now that we know this powerful new command. Go ahead and delete the test directory. Did you remember to use sudo before the rmdir command? Check to make sure the directory is gone. You might be asking yourself the question: why can we list the contents of the /var directory but not make changes? That’s because all users have read access to the /var directory and the ls command is a read function. Only the root users or those acting as a super-user can write changes to the directory. Let’s go back to our home directory: $ cd ~ Editing text files is a really common task on Linux systems because many of the application configuration files are text files. We can create a text file by using a text editor. Type in: $ nano myfile.conf The shell starts up the nano text editor and places your terminal cursor in the editing screen. Nano is a simple text-based word processor. Type in a few lines of text. When you’re done writing your novel, hit ctrl-x and answer y to the prompt to save your work. Finally, hit enter to save the text to the filename you specified. Check to see that your file was saved in the directory. You can take a look at the contents of your file by typing: $ cat myfile.conf The cat command displays your text file content on the terminal screen. This command works fine for displaying small text files. But if your file is hundreds of lines long, the content will scroll down your terminal screen so fast that you won’t be able to easily read it. There’s a better way to view larger text files. Type in: $ less myfile.conf The less command will page the display of a text file, allowing you to page through the contents of the file using the space bar. Your text file is probably too short to see the paging in action though. Hit q to quit out of the less text viewer. Hit the up-arrow key on your keyboard a few times until the commmand nano myfile.conf appears next to your command prompt. Cool, huh? The up-arrow key allows you to replay a previously run command. Linux maintains a list of all the commands you have run since you logged into the server. This is called the command history. It’s a really useful feature if you have to re-run a complex command again. Now, hit ctrl-c. This cancels whatever command is displayed on the command line. Type in the following command to create a couple empty files in the directory: $ touch file1 file2 file3 Confirm that the files were created. Some commands, like touch. allow you to specify multiple files as arguments. You will find that Linux commands have all kinds of ways to make tasks more efficient like this. Throughout this assignment, we have been running commands and viewing results on the terminal screen. The screen is the standard place for commands to output results. It’s known as the standard out (stdout). However, it’s really useful to output results to the file system sometimes. Type in: $ ls > listing.txt Take a look at the directory listing now. You just created a new file. View the contents of the listing.txt file. What do you see? Instead of sending the output from the ls command to the screen we sent it to a text file. Let’s try another one. Type: $ cat myfile.conf > listing.txt Take a look at the contents of the listing.txt file again. It looks like your myfile.conf file now. It’s like you made a copy of it. But what happened to the previous content in the listing.txt file? When you redirect the output of a command using the right angle-bracket character (>), the output overwrites the existing file. Type this command in: $ cat myfile.conf >> listing.txt Now look at the contents of the listing.txt file. You should see your original content displayed twice. When you use two angle-bracket characters in the commmand the output appends (or adds to) the file instead of overwriting it. We redirected the output from a command to a text file. It’s also possible to redirect the input to a command. Typically we use a keyboard to provide input, but sometimes it makes more sense to input a file to a command. For example, how many words are in your new listing.txt file? Let’s find out. Type in: $ wc -w < listing.txt Did you get a number? This command inputs the listing.txt file into a word count program called wc. Type in the command: $ ls /usr/bin The terminal screen probably scrolled quickly as filenames flashed by. The /usr/bin directory holds quite a few files. It would be nice if we could page through the contents of this directory. Well, we can. We can use a special shell feature called pipes. In previous steps, we redirected I/O using the file system. Pipes allow us to redirect I/O between programs. We can redirect the output from one program into another. Type in: $ ls /usr/bin | less Now the directory listing is paged. Hit the spacebar to page through the listing. The pipe, represented by a vertical bar character (|), takes the output from the ls command and redirects it to the less command where the resulting output is paged. Pipes are super powerful and used all the time by savvy Linux operators. Hit the q key to quit the paginated directory listing command. Working with shell scripts Now things are going to get interesting. We’ve been manually typing in commands throughout this exercise. If we were running a set of repetitive tasks, we would want to automate the process as much as possible. The shell makes it really easy to automate tasks using shell scripts. The shell provides many of the same features as a basic procedural programming language. Let’s write some code. Type in this command: $ j=123 $ echo $j We just created a variable named j referencing the string 123. The echo command printed out the value of the variable. We had to use a dollar sign ($) when referencing the variable in another command. Next, type in: $ j=1+1 $ echo $j Is that what you expected? The shell just interprets the variable value as a string. It’s not going to do any sort of computation. Typing in shell script commands on the command line is sort of pointless. We want to be able to create scripts that we can run over-and-over. Let’s create our first shell script. Use the nano editor to create a file named myscript. When the file is open in the editor, type in the following lines of code: #!/bin/bash echo Hello $1 Now quit the editor and save your file. We can run our script by typing: $ ./myscript World Er, what happened? Permission denied. Didn’t we create this file? Why can’t we run it? We can’t run the script file because we haven’t set the execute permission on the file. Type in: $ chmod u+x myscript This modifies the file access control list to allow the owner of the file to execute it. Let’s try to run the command again. Hit the up-arrow key a couple times until the ./myscript World command is displayed and hit enter. Hooray! Our first shell script. It’s probably a bit underwhelming. No problem, we’ll make it a little more complex. The script took a single argument called World. Any arguments provided to a shell script are represented as consecutively numbered variables inside the script ($1, $2, etc). Pretty simple. You might be wondering why we had to type the ./ characters before the name of our script file. Try to type in the command without them: $ myscript World Command not found. That seems a little weird. Aren’t we currently in the directory where the shell script is located? Well, that’s just not how the shell works. When you enter a command into the shell, it looks for the command in a predefined set of directories on the server called your PATH. Since your script file isn’t in your special path, the shell reports it as not found. By typing in the ./ characters before the command name you are basically forcing the shell to look for your script in the current directory instead of the default path. Create another file called cleanup using nano. In the file editor window type: #!/bin/bash # My cleanup script mkdir archive mv file* archive Exit the editor window and save the file. Change the permissions on the script file so that you can execute it. Now run the command: $ ./cleanup Take a look at the file directory listing. Notice the archive directory? List the contents of that directory. The script automatically created a new directory and moved three files into it. Anything you can do manually at a command prompt can be automated using a shell script. Let’s create one more shell script. Use nano to create a script called namelist. Here is the content of the script: #!/bin/bash # for-loop test script names='Jason John Jane' for i in $names do echo Hello $i done Change the permissions on the script file so that you can execute it. Run the command: $ ./namelist The script will loop through a set of names stored in a variable displaying each one. Scripts support several programming constructs like for-loops, do-while loops, and if-then-else. These building blocks allow you to create fairly complex scripts for automating tasks. Installing packages and services We’re nearing the end of this assignment. But before we finish, let’s install some new software packages on our server. The first thing we should do is make sure all the current packages installed on our Linux server are up-to-date. Type in: $ sudo yum update -y This is one of those really powerful commands that requires sudo access. The system will review the currently installed packages and go out to the Internet and download appropriate updates. Next, let’s install an Apache web server on our system. Type in: $ sudo yum install httpd -y Bam! You probably never knew that installing a web server was so easy. We’re not going to actually use the web server in this exercise, but we will in future assignments. We installed the web server, but is it actually running? Let’s check. Type in: $ sudo service httpd status Nope. Let’s start it. Type: $ sudo service httpd start We can use the service command to control the services running on the system. Let’s setup the service so that it automatically starts when the system boots up. Type in: $ sudo chkconfig httpd on Cool. We installed the Apache web server on our system, but what other programs are currently running? We can use the pscommand to find out. Type in: $ ps -ax Lots of processes are running on our system. We can even look at the overall performance of our system using the topcommand. Let’s try that now. Type in: $ top The display might seem a little overwhelming at first. You should see lots of performance information displayed including the cpu usage, free memory, and a list of running tasks. We’re almost across the finish line. Let’s make sure all of our valuable work is stored in a git repository. First, we need to install git. Type in the command: $ sudo yum install git -y Check your work It’s very important to check your work before submitting it for grading. A misspelled, misplaced or missing file will cost you points. This may seem harsh, but the reality is that these sorts of mistakes have consequences in the real world. For example, a server instance could fail to launch properly and impact customers because a single required file is missing. Here is what the contents of your git repository should look like before final submission: ┣archive ┃ ┣ file1 ┃ ┣ file2 ┃ ┗ file3 ┣ namelist ┗ myfile.conf Saving our work in the git repository Next, make sure you are still in your home directory (/home/ec2-user). We will install the git repository you created at the beginning of this exercise. You will need to modify this command by typing in the GitHub repository URL you copied earlier. $ git clone <your GitHub URL here>.git Example: git clone https://github.com/UST-SEIS665/hw2-seis665-02-spring2019-<your github id>.git The git application will ask you for your GitHub username and password. Note, if you have multi-factor authentication enabled on your GitHub account you will need to provide a personal token instead of your password. Git will clone (copy) the repository from GitHub to your Linux server. Since the repository is empty the clone happens almost instantly. Check to make sure that a sub-directory called "hw2-seis665-02-spring2019-<username>" exists in the current directory (where <username> is your GitHub account name). Git automatically created this directory as part of the cloning process. Change to the hw2-seis665-02-spring2019-<username> directory and type: $ ls -la Notice the .git hidden directory? This is where git actually stores all of the file changes in your repository. Nothing is actually in your repository yet. Change back to the parent directory (cd ..). Next, let’s move some of our files into the repository. Type: $ mv archive hw2-seis665-02-spring2019-<username> $ mv namelist hw2-seis665-02-spring2019-<username> $ mv myfile.conf hw2-seis665-02-spring2019-<username> Hopefully, you remembered to use the auto-complete function to reduce some of that typing. Change to the hw2-seis665-02-spring2019-<username> directory and list the directory contents. Your files are in the working directory, but are not actually stored in the repository because they haven’t been committed yet. Type in: $ git status You should see a list of untracked files. Let’s tell git that we want these files tracked. Type in: $ git add * Now type in the git status command again. Notice how all the files are now being tracked and are ready to be committed. These files are in the git staging area. We’ll commit them to the repository next. Type: $ git commit -m 'assignment 2 files' Next, take a look at the commit log. Type: $ git log You should see your commit listed along with an assigned hash (long string of random-looking characters). Finally, let’s save the repository to our GitHub account. Type in: $ git push origin master The git client will ask you for your GitHub username and password before pushing the repository. Go back to the GitHub.com website and login if you have been logged out. Click on the repository link for the assignment. Do you see your files listed there? Congratulations, you completed the exercise! Terminate server The last step is to terminate your Linux instance. AWS will bill you for every hour the instance is running. The cost is nominal, but there’s no need to rack up unnecessary charges. Here are the steps to terminate your instance: Log into your AWS account and click on the EC2 dashboard. Click the Instances menu item. Select your server in the instances table. Click on the Actions drop down menu above the instances table. Select the Instance State menu option Click on the Terminate action. Your Linux instance will shutdown and disappear in a few minutes. The EC2 dashboard will continue to display the instance on your instance listing for another day or so. However, the state of the instance will be terminated. Submitting your assignment — IMPORTANT! If you haven’t already, please e-mail me your GitHub username in order to receive credit for this assignment. There is no need to email me to tell me that you have committed your work to GitHub or to ask me if your GitHub submission worked. If you can see your work in your GitHub repository, I can see your work.
SOYJUN / TCP Socket Client ServerThe aim of this assignment is to have you do TCP socket client / server programming using I/O multiplexing, child processes and threads. It also aims at getting you to familiarize yourselves with the inetd superserver daemon, the ‘exec’ family of functions, various socket error scenarios, some socket options, and some basic domain name / IP address conversion functions. Apart from the material in Chapters 1 to 6 covered in class, you will also need to refer to the following : the exec family of functions (Section 4.7 of Chapter 4) using pipes for interprocess communication (IPC) in Unix error scenarios induced by process terminations & host crashes (Sections 5.11 to 5.16, Chapter 5) setsockopt function & SO_REUSEADDR socket option (Section 7.2 & pp.210-213, Chapter 7) gethostbyname & gethostbyaddr functions (Sections 11.3 & 11.4, Chapter 11) the basic structure of inetd (Section 13.5, Chapter 13) programming with threads (Sections 26.1 to 26.5, Chapter 26) Overview I shall present an overview of this assignment and discuss some of the specification details given below in class on Wednesday, September 17 & Monday, September 22. Client The client is evoked with a command line argument giving either the server IP address in dotted decimal notation, or the server domain name. The client has to be able to handle either mode and figure out which of the two is being passed to it. If it is given the IP address, it calls the gethostbyaddr function to get the domain name, which it then prints out to the user in the form of an appropriate message (e.g., ‘The server host is compserv1.cs.stonybrook.edu’). The function gethostbyname, on the other hand, returns the IP address that corresponds to a given domain name. The client then enters an infinite loop in which it queries the user which service is being requested. There are two options : echo and time (note that time is a slightly modified version of the daytime service – see below). The client then forks off a child. After the child is forked off, the parent process enters a second loop in which it continually reads and prints out status messages received from the child via a half-duplex pipe (see below). The parent exits the second loop when the child closes the pipe (how does the parent detect this?), and/or the SIGCHLD signal is generated when the child terminates. The parent then repeats the outer loop, querying the user again for the (next) service s/he desires. This cycle continues till the user responds to a query with quit rather than echo or time. The child process is the one which handles the actual service for the user. It execs (see Section 4.7, Chapter 4) an xterm to generate a separate window through which all interactions with server and user take place. For example, the following exec function call evokes an xterm, and gets the xterm to execute echocli, located in the current directory, passing the string 127.0.0.1 (assumed to be the IP address of the server) as the command line argument argv[1] to echocli (click on the url for further details) : execlp("xterm", "xterm", "-e", "./echocli", "127.0.0.1", (char *) 0) xterm executes one of two client programs (echocli or timecli, say) depending on the service requested. A client program establishes a TCP connection to the server at the ‘well-known port’ for the service (in reality, this port will, of course, be some ephemeral port of your choosing, the value of which is known to both server and client code). All interaction with the user, on the one hand, and with the server, on the other, takes place through the child’s xterm window, not the parent’s window. On the other hand, the child will use a half-duplex pipe to relay status information to the parent which the parent prints out in its window (see below).To terminate the echo client, the user can type in ^D (CTRL D, the EOF character). To terminate the time client, the only option is for the user to type in ^C (CTRL C). (This can also be used as an alternative means of terminating the echo client.) Note that using ^C in the context of the time service will give the server process the impression that the client process has ‘crashed’. It is your responsibility to ensure that the server process handles this correctly and closes cleanly. I shall address this further when discussing the server process. It is also part of your responsibility in this assignment to ensure that the client code is robust with respect to the server process crashing (see Sections 5.12 & 5.13, Chapter 5). Amongst other implications, this means that it would probably be a good idea for you to implement your echo client code along the lines of either : Figure 6.9, p.168 (or even Figure 6.13, p.174) which uses I/O multiplexing with the select function; or of Figure 26.2, p.680, which uses threads; rather than along the lines of Figure 5.5, p.125. When the child terminates, either normally or abnormally, its xterm window disappears instantaneously. Consequently, any status information that the child might want to communicate to the user should not be printed out on the child’s xterm window, since the user will not have time to see the final such message before the window disappears. Instead, as the parent forks off the child at the beginning, a half-duplex pipe should be established from child to parent. The child uses the pipe to send status reports to the parent, which the parent prints out in its window. I leave it up to you to decide what status information exactly should be relayed to the parent but, at a minimum, the parent should certainly be notified, in as precise terms as possible, of any abnormal termination conditions of the service provided by the child. In general, you should try to make your code as robust as possible with respect to handling errors, including confused behaviour by the user (e.g., passing an invalid command line argument; responding to a query incorrectly; trying to interact with the service through the parent process window, not the child process xterm; etc.). Amongst other things, you have to worry about EINTR errors occurring during slow system calls (such as the parent reading from the pipe, or, possibly, printing to stdout, for example) due to a SIGCHLD signal. What about other kinds of errors? Which ones can occur? How should you handle them? Server The server has to be able to handle multiple clients using threads (specifically, detached threads), not child processes (see Sections 26.1 to 26.4, Chapter 26). Furthermore, it has to be able to handle multiple types of service; in our case, two : echo and time. echo is just the standard echo service we have seen in class. time is a slightly modified version of the daytime service (see Figure 1.9, p.14) : instead of sending the client the ‘daytime’ just once and closing, the service sits in an infinite loop, sending the ‘daytime’, sleeping for 5 seconds, and repeating, ad infinitum. The server is loosely based on the way the inetd daemon works : see Figure 13.7, p.374. However, note that the differences between inetd and our server are probably more significant than the similarities: inetd forks off children, whereas our server uses threads; inetd child processes issue exec commands, which our server threads do not; etc. So you should treat Figure 13.7 (and Section 13.5, Chapter 13, generally) as a source of ideas, not as a set of specifications which you must slavishly adhere to and copy. Note, by the way, that there are some similarities between our client and inetd (primarily, forking off children which issue execs), which could be a useful source of ideas. The server creates a listening socket for each type of service that it handles, bound to the ‘well-known port’ for that service. It then uses select to await clients (Chapter 6; or, if you prefer, poll; note that pselect is not supported in Solaris 2.10). The socket on which a client connects identifies the service the client is seeking. The server accepts the connection and creates a thread which provides the service. The thread detaches itself. Meanwhile, the main thread goes back to the select to await further clients. A major concern when using threads is to make sure that operations are thread safe (see p.685 and on into Section 26.5). In this respect, Stevens’ readline function (in Stevens’ file unpv13e/lib/readline.c, see Figure 3.18, pp.91-92) poses a particular problem. On p.686, the authors give three options for dealing with this. The third option is too inefficient and should be discarded. You can implement the second option if you wish. Easiest of all would be the first option, since it involves using a thread-safe version of readline (see Figures 26.11 & 26.12) provided in file unpv13e/threads/readline.c. Whatever you do, remember that Stevens’ library, libunp.a, contains the non-thread-safe version of Figure 3.18, and that is the version that will be link-loaded to your code unless you undertake explicit steps to ensure this does not happen (libunp.a also contains the ‘wrapper’ function Readline, whose code is also in file unpv13e/lib/readline.c). Remaking your copy of libunp.a with the ‘correct’ version of readline is not a viable option because when you hand in your code, it will be compiled and link-loaded with respect to the version of libunp.a in the course account, ~cse533/Stevens/unpv13e_solaris2.10 (I do not intend to change that version since it risks creating confusion later on in the course). Also, you will probably want to use the original version of readline in the client code anyway. I am providing you with a sample Makefile which picks up the thread-safe version of readline from directory ~cse533/Stevens/unpv13e_solaris2.10/threads and uses it when making the executable for the server, but leaves the other executables it makes to link-load the non-thread-safe version from libunp.a. Again, it is part of your responsibility to make sure that your server code is as robust as possible with respect to errors, and that the server threads terminate cleanly under all circumstances. Recall, first of all, that the client user will often use ^C (CTRL C) in the xterm to terminate the service. This will appear to the server thread as if the client process has crashed. You need to think about the error conditions that will be induced (see Sections 5.11 to 5.13, Chapter 5), and how the echo and time server code is to detect and handle these conditions. For example, the time server will almost certainly experience an EPIPE error (see Section 5.13). How should the associated SIGPIPE signal be handled? Be aware that when we return out of the Stevens’ writen function with -1 (indicating an error) and check errno, errno is sometimes equal to 0, not EPIPE (value 32). This can happen under Solaris 2.10, but I am not sure under precisely what conditions nor why. Nor am I sure if it also happens under other Unix versions, or if it also happens when using write rather than writen. The point is, you cannot depend on errno to find out what has happened to the write or writen functions. My suggestion, therefore, is that the time server should use the select function. On the one hand, select’s timeout mechanism can be used to make the server sleep for the 5 seconds. On the other hand, select should also monitor the connection socket read event because, when the client xterm is ^C’ed, a FIN will be sent to the server TCP, which will prime the socket for reading; a read on the socket will then return with value 0 (see Figure 14.3, p. 385 as an example). But what about errors other than EPIPE? Which ones can occur? How should you handle them? Recall, as well, that if a thread terminates without explicitly closing the connection socket it has been using, the connection socket will remain existent until the server process itself dies (why?). Since the server process is supposed, in principle, to run for ever, you risk ending up with an ever increasing number of unused, ‘orphaned’ sockets unless you are careful. Whenever a server thread detects the termination of its client, it should print out a message giving appropriate details: e.g., “Client termination: EPIPE error detected”, “Client termination: socket read returned with value 0”, “Client termination: socket read returned with value -1, errno = . . .”, and so on. When debugging your server code, you will probably find that restarting the server very shortly after it was last running will give you trouble when it comes to bind to its ‘well-known ports’. This is because, when the server side initiates connection termination (which is what will happen if the server process crashes; or if you kill it first, before killing the client) TCP keeps the connections open in the TIME_WAIT state for 2MSLs (Sections 2.6 & 2.7, Chapter 2). This could very quickly become a major irritant. I suggest you explore the possibility of using the SO_REUSEADDR socket option (pp.210-213, Chapter 7; note that the SO_REUSEPORT socket option is not supported in Solaris 2.10), which should help keep the stress level down. You will need to use the setsockopt function (Section 7.2) to enable this option. Figure 8.24, p.263, shows an instance of server code that sets the SO_REUSEADDR socket option. Finally, you should be aware of the sort of problem, described in Section 16.6, pp.461-463, that might occur when (blocking) listening sockets are monitored using select. Such sockets should be made nonblocking, which requires use of the fcntl function after socket creates the socket, but before listen turns the socket into a listening socket.

attaoveisi / Extended State Observera disturbance rejection-based solution to the problem of robust output regulation of linear systems. The difference between the underlying plant and its nominal mathematical model is represented by two classes of disturbances. The first class is generated by an autonomous linear system while the other class has no specific dynamical structure. Robustness against the first disturbance class is achieved by the internal model principle. Next, in the framework of disturbance rejection control, an extended state observer (ESO) is designed to estimate and compensate for the second class of disturbances. As a result, the proposed output regulation method can deal with a vast range of uncertainties. The stability of the closed loop system is investigated and results on practical regulation are drawn. Keywords—Output regulation, extended state observer, disturbance rejection, linear system, robustness

attaoveisi / Disturbance ObserverIn this note, disturbance rejection control (DRC) based on unknown input observation (UIO), and disturbance-observer based control (DOBC) methods are revisited for a class of MIMO systems with mismatch disturbance conditions. In both of these methods, the estimated disturbance is considered to be in the feedback channel. The disturbance term could represent either unknown mismatched signals penetrating the states, or unknown dynamics not captured in the modeling process, or physical parameter variations not accounted for in the mathematical model of the plant. Unlike the high-gain approaches and variable structure methods, a systematic synthesis of the state/disturbance observer-based controller is carried out. For this purpose, first, using a series of singular value decompositions, the linearized plant is transformed into disturbance-free and disturbance-dependent subsystems. Then, functional state reconstruction based on generalized detectability concept is proposed for the disturbance-free part. Then, a DRC based on quadratic stability theorem is employed to guarantee the performance of the closed-loop system. An important contribution offered in this article is the independence of the estimated disturbance from the control input which seem to be missing in the literature for disturbance decoupling problems. In the second method, DOBC is reconsidered with the aim of achieving a high level of robustness against modeling uncertainties and matched/mismatched disturbances, while at the same time retaining performance. Accordingly, unlike the first method, DRC, full information state observation is developed independent of the disturbance estimation. An advantage of such a combination is that disturbance estimation does not involve output derivatives. Finally, the case of systems with matched disturbances is presented as a corollary of the main results.
SpaceNetLab / SpaceRTC ProjectUser-perceived latency is important for the quality of experience (QoE) of wide-area real-time communications (RTC). This paper explores a futuristic yet important problem facing the RTC community: can we exploit emerging mega-constellations to facilitate low-latency RTC globally? We carry out our quest in three steps. First, through a measurement study associated with a large number of geo-distributed RTC users, we quantitatively expose that the meandering routes over the client-cloud segment and the inter-cloud-site segment in existing cloud-based RTC architecture are critical culprits for the high latency issue suffered by wide-area RTC sessions. Second, after analyzing the low-latency potential enabled by mega-constellations, we formulate the dynamic RTC latency minimization problem under the integrated space-ground environment, and propose SpaceRTC, a satellite-cloud cooperative framework that adaptively selects relay servers upon satellites and cloud sites to build an overlay network which enables diverse close-to-optimal paths, and then judiciously allocates RTC flows in the network to facilitate low-latency interactions. Finally, we implement a hardware-in-the-loop experimental environment based on public constellation information and RTC trace, and extensive experiments demonstrate that SpaceRTC can deliver near-optimal interactive latency, with up to 64.9% latency reduction as compared with other state-of-the-art cloud-based solutions under representative videoconferencing traffic.
