BlockchainLabs / PebblecoinPebblecoin UPDATE 2015/12/31: Version 0.4.4.1 is now out. The major change is optimizing the daemon to use less RAM. It no longer keeps all the blocks, which are rarely needed, in RAM, and so RAM usage has decreased from around 2 gigabytes, to under 200 megabytes. Mac binaries are also now available. The new wallet is compatible with the old wallet - simply turn off the old wallet, and start the new wallet, and the blockchain will update automatically to use less RAM. Code: Release Notes 0.4.4.1 - (All) Fix blockchain RAM usage, from almost 2 GB to less than 200 MB - Seamless blockchain conversion on first run with new binaries - (Qt) Fix high CPU usage - (Qt) Fix sync indicator (# of total blocks) - (Mac) Mac binaries - Technical Notes: - (All) Blockchain disk-backed storage with sqlite3 and stxxl - (Mac) Fix mac compilation - (All) Update build files & instructions for linux, mac, windows - (All) Remove unused protobuf and OpenSSL dependencies for Qt wallet - (Tests) Fix valgrind errors - (Tests) Use local directory for blockchain instead of default directory - (Tests) Run tests on Windows if using new enough MSVC LINKS: Windows 64-bit: https://www.dropbox.com/s/b4kubwwnb4t7o4w/pebblecoin-all-win32-x64-v0.4.4.1.zip?dl=0 Mac 64-bit: https://www.dropbox.com/s/uoy9z1oxu4x53cv/pebblecoin-all-mac-x64-v0.4.4.1.tar.gz?dl=0 Linux 64-bit: https://www.dropbox.com/s/jq3h3bc29jmndks/pebblecoin-all-linux-x64-v0.4.4.1.tar.gz?dl=0 Exchange: https://poloniex.com/exchange#btc_xpb . Source: https://github.com/xpbcreator/pebblecoin/ CONTACT: xpbcreator@torguard.tg IRC: irc.freenode.net, #pebblecoin UPDATE 2015/06/08: Version 0.4.3.1 is now out. This is a minor, mostly bug-fix release. Work continues on the next major release which will bring us user-created currencies and user-graded contracts. Release notes: Code: Release Notes 0.4.3.1 - RPC calls for DPOS: - getdelegateinfos RPC call - get kimageseqs RPC call - block header contains signing_delegate_id - fix checkpoint rollback bug - fix inability to send coins if voting history was lost UPDATE 2015/05/04: Version 0.4.2.2 is now out. This is a bug-fix/cosmetic release. Release notes: Payment ID support Windows installer Logos updated Improved DPOS tab Sync issues fully fixed Fix rare crash bug Fix min out 0 bug Fix debit display Fix GUI not updating Updated hard-coded seed nodes UPDATE 2015/04/24: The switch-over to DPOS has succeeded without a hitch! DPOS blocks are being signed as we speak, at the far faster pace of 15 seconds per block. This marks the start of a new era for Pebblecoin. UPDATE 2015/04/21: Congratulations to the first registered delegate! This indicates the start of the forking change so everybody please update your daemons if you haven't already. To promote the coin and encourage people to become delegates, we've come up with an incentive scheme. First, we'll send a free 100 XPB to anybody who PMs me their public address, for people to play around with and to start using the coin. Second, once DPOS starts, for the first month of DPOS I'll send an extra 0.5 XPB to the signing delegate for every block they process. This is on top of the usual transaction fees they will receive. This is to encourage more people to become delegates at this important phase of the coin. UPDATE 2015/04/19: All went well on the testnet release, so after a few further minor modifications, we are releasing version 0.4.1.2 to the public. This is a forking change, so please update your clients and servers (links below). At block 83120, sometime on April 21st, registration for DPOS delegates will begin. At block 85300, sometime on April 24th, the network will switch over to DPOS. As with the testnet, to become a delegate and receive block fees for securing the network, just turn on your wallet, register to be a delegate (5 XPB fee), and then leave your wallet on. It will sign the blocks when it is your turn. While Roman works on the next phase of the release - introducing subcurrencies - I will be fixing up some loose ends on the wallet, adding payment ID support, etc. This is truly an exciting time for Pebblecoin. RELEASE NOTES: All clients adjust internal clocks using ntp (client list in src/common/ntp_time.cpp) Added testnet support DPOS registration starts Block 83120 (~April 21st) DPOS phase starts Block 85300 (~April 24th) Default fee bumped to 0.10 XPB Low-free transactions no longer get relayed by default Significantly improved wallet sync Checkpoint at Block 79000 TOTAL CURRENT COINS: Available at this link. BLOCK TARGET TIME: 2 minutes EXPECTED EMISSION: At Block 3600 (End of Day 5): ~78 XPBs At Block 6480 (End of Day 9): ~758 XPBs At Block 9360 (End of Day 13): 6,771.0 XPBs At Block 12240 (End of Day 17): ~61,000 XPBs At Block 15120 (End of Day 21): ~550,000 XPBs, start of regular 300/block emission At Block 21900 (End of Month 1): ~2,600,000 XPBs, 300/block At Block 43800 (End of Month 2): ~9,150,000 XPBs, 300/block At Block 85300 (End of POW phase): ~21,500,300 XPBs. UPDATE: The Pebblecoin Pool is now live! Instructions: Download the linux miner and run it: ./minerd -o stratum+tcp://69.60.113.21:3350 -u YOUR_WALLET_ADDRESS -p x UPDATE: The Pebblecoin wallet is now live! There have been thousands of attempts at alternative currencies in the community. Many are 100% copies of existing blockchains with a different name. Some are very slight variations with no significant differences. From recent history it is apparent the only realistic chance for viability of a new currency is one that is innovation and continued support and development. The bitcoin community for good reason has shown interest in currencies that provide privacy of transactions, several currencies such as darkcoin, have become popular based on this desire. The best technology for privacy is cryptonote although for a variety of reasons there hasnt been much development for ease of use, and as a result there has not been significant adoption. Pebblecoin (XPB) is a cryptonote based coin with improvements and changes in some areas, and the promise of development in others. I invite developers to work on this technology with me. There is no premine, any tips or support of any developer including myself will be completely voluntary. These are the following areas which I have determined needs changes/updates: I welcome suggestions, and am interested what else I can try to improve. 1) New Mining algorithm (active) A mining algorithm is either susceptible to ASIC development or to being botnetted, meaning it is either more efficient to have a centralized mining entity (as is the case with bitcoin) or to have an algorithm that requires a real CPU, in which case botnets become very attractive. To my knowledge there does not exist a blockchain that attempts to solve both problems, by having an algorithm that only works on a general purpose computer and is difficult to botnet. Cryptonote coins currently are primarily mined with botnets. Boulderhash is a new mining algorithm requiring 13 GB RAM, nearly eliminating all possible zombie (botnet controlled) computers from mining. Most infected computers in the world do not have 13 GB available, so an algorithm that requires that much RAM severely limits the productivity of a botnet. 13 GB also makes ASICs cost prohibitive, and the current GPUs do not have that much RAM. What's left is general purpose computers as was the original intent of bitcoin's mining process. 2) Distribution of coins (active) It is very common in the launch of a new cryptocurrency the distribution algorithm heavily is weighted towards the very early adopters. Such distribution is designed to give a massive advantage to people who are fully prepared to mine at launch, with a very large difference shortly after sometimes a few days later. If the point of mining is to both secure the network and fairly distribute coins a gradual build up of rewards makes more sense, with no drop off in mining rewards. At a standard block reward of 300, at launch each block will reward 0.3 coins leading up to 3, 30, and finally the standard reward of 300 which will be the standard unchanging reward from that point. It will take approximately 3 weeks for the block reward of 300 to be reached. 3) GUI Software (active) There are no current cryptonote coins that have a downloadable GUI, which makes the user experience much worse than that of bitcoin. It is hard to achieve signficant adoption with a command line interface. The very first update had the exact GUI written for bitcoin fully working with Pebblecoin. The GUI was released on Jan 19, before the full 300 XPB reward was awarded for winning the block. 4) IRC Chat support embedded in Client GUI (active) For user support, and to talk to core developers message boards such as Bitcointalk and reddit are primarily used. I have embedded an IRC client in the GUI and be available at set hours for any kind of support. 5) Address aliasing (to be worked on) Just as a user visiting google does not need to know the ip address, similarly an address should have the ability to have an associated userid. If I ask a friend to send me pebblecoins it would be easier to tell him send it to @myuserid rather than a very long address or scanning a QR code. There should be a way of registering a userid on the blockchain that will permanently translate to a pebblecoin addresss. QT INSTRUCTIONS: Download the package for your respective platform Run the Qt executable. The software will generate a new wallet for you and use a default folder: ~/.pebblecoin on Linux and %appdata%\pebblecoin on Windows. To use an existing wallet, copy the wallet.keys file into the default folder. To use a different data directory and/or wallet file, run the software like so: ./pebblecoin-qt --data-dir <DataDir> --wallet-file <FileName>. To enable mining, run the start_mining_NEEDS_13GB_RAM.bat batch file. Or run the qt wallet with the --enable-boulderhash command line option, or put enable-boulderhash=1 into the config file. It will start mining to the wallet address. To change the number of mining threads (13GB required per thread), do --mining-threads <NumThreads> or edit the batch file. DAEMON + SIMPLEWALLET INSTRUCTIONS: Download the package, run: ./pebblecoind --data-dir pebblecoin_data Once the daemon finished syncing, run the simplewallet: ./simplewallet POOL INSTRUCTIONS: Download the miner binary for your platform. Run the miner using a wallet address gotten from simplewallet or the Qt Wallet: Code: minerd -o stratum+tcp://69.60.113.21:3350 -u YOUR_WALLET_ADDRESS -p x [/li] DEV WALLET (for donations): PByFqCfuDRUPVsNrzrUXnuUdF7LpXsTTZXeq5cdHpJDogbJ8EBXopciN7DmQiGhLEo5ArA7dFqGga2A AhbRaZ2gL8jjp9VmYgk

Ch-Jad / CH JaDi Rajput1# Cmder [](https://gitter.im/cmderdev/cmder?utm_source=badge&utm_medium=badge&utm_campaign=pr-badge&utm_content=badge) [](https://ci.appveyor.com/project/MartiUK/cmder) Cmder is a **software package** created out of pure frustration over absence of usable console emulator on Windows. It is based on [ConEmu](https://conemu.github.io/) with *major* config overhaul, comes with a Monokai color scheme, amazing [clink](https://chrisant996.github.io/clink/) (further enhanced by [clink-completions](https://github.com/vladimir-kotikov/clink-completions)) and a custom prompt layout.  ## Why use it The main advantage of Cmder is portability. It is designed to be totally self-contained with no external dependencies, which makes it great for **USB Sticks** or **cloud storage**. So you can carry your console, aliases and binaries (like wget, curl and git) with you anywhere. The Cmder's user interface is also designed to be more eye pleasing, and you can compare the main differences between Cmder and ConEmu [here](https://conemu.github.io/en/cmder.html). ## Installation ### Single User Portable Config 1. Download the [latest release](https://github.com/cmderdev/cmder/releases/) 2. Extract the archive. *Note: This path should not be `C:\Program Files` or anywhere else that would require Administrator access for modifying configuration files* 3. (optional) Place your own executable files into the `%cmder_root%\bin` folder to be injected into your PATH. 4. Run `Cmder.exe` ### Shared Cmder install with Non-Portable Individual User Config 1. Download the [latest release](https://github.com/cmderdev/cmder/releases/) 2. Extract the archive to a shared location. 3. (optional) Place your own executable files and custom app folders into the `%cmder_root%\bin`. See: [bin/README.md](./bin/Readme.md) - This folder to be injected into your PATH by default. - See `/max_depth [1-5]` in 'Command Line Arguments for `init.bat`' table to add subdirectories recursively. 4. (optional) Place your own custom app folders into the `%cmder_root%\opt`. See: [opt/README.md](./opt/Readme.md) - This folder will NOT be injected into your PATH so you have total control of what gets added. 5. Run `Cmder.exe` with `/C` command line argument. Example: `cmder.exe /C %userprofile%\cmder_config` * This will create the following directory structure if it is missing. ``` c:\users\[CH JaDi Rajput]\cmder_config ├───bin ├───config │ └───profile.d └───opt ``` - (optional) Place your own executable files and custom app folders into `%userprofile%\cmder_config\bin`. - This folder to be injected into your PATH by default. - See `/max_depth [1-5]` in 'Command Line Arguments for `init.bat`' table to add subdirectories recursively. - (optional) Place your own custom app folders into the `%user_profile%\cmder_config\opt`. - This folder will NOT be injected into your PATH so you have total control of what gets added. * Both the shared install and the individual user config locations can contain a full set of init and profile.d scripts enabling shared config with user overrides. See below. ## Cmder.exe Command Line Arguments | Argument | Description | | ------------------- | ----------------------------------------------------------------------- | | `/C [user_root_path]` | Individual user Cmder root folder. Example: `%userprofile%\cmder_config` | | `/M` | Use `conemu-%computername%.xml` for ConEmu settings storage instead of `user_conemu.xml` | | `/REGISTER [ALL, USER]` | Register a Windows Shell Menu shortcut. | | `/UNREGISTER [ALL, USER]` | Un-register a Windows Shell Menu shortcut. | | `/SINGLE` | Start Cmder in single mode. | | `/START [start_path]` | Folder path to start in. | | `/TASK [task_name]` | Task to start after launch. | | `/X [ConEmu extras pars]` | Forwards parameters to ConEmu | ## Context Menu Integration So you've experimented with Cmder a little and want to give it a shot in a more permanent home; ### Shortcut to open Cmder in a chosen folder 1. Open a terminal as an Administrator 2. Navigate to the directory you have placed Cmder 3. Execute `.\cmder.exe /REGISTER ALL` _If you get a message "Access Denied" ensure you are executing the command in an **Administrator** prompt._ In a file explorer window right click in or on a directory to see "Cmder Here" in the context menu. ## Keyboard shortcuts ### Tab manipulation * <kbd>Ctrl</kbd> + <kbd>T</kbd> : New tab dialog (maybe you want to open cmd as admin?) * <kbd>Ctrl</kbd> + <kbd>W</kbd> : Close tab * <kbd>Ctrl</kbd> + <kbd>D</kbd> : Close tab (if pressed on empty command) * <kbd>Shift</kbd> + <kbd>Alt</kbd> + <kbd>#Number</kbd> : Fast new tab: <kbd>1</kbd> - CMD, <kbd>2</kbd> - PowerShell * <kbd>Ctrl</kbd> + <kbd>Tab</kbd> : Switch to next tab * <kbd>Ctrl</kbd> + <kbd>Shift</kbd> + <kbd>Tab</kbd> : Switch to previous tab * <kbd>Ctrl</kbd> + <kbd>#Number</kbd> : Switch to tab #Number * <kbd>Alt</kbd> + <kbd>Enter</kbd>: Fullscreen ### Shell * <kbd>Ctrl</kbd> + <kbd>Alt</kbd> + <kbd>U</kbd> : Traverse up in directory structure (lovely feature!) * <kbd>End</kbd>, <kbd>Home</kbd>, <kbd>Ctrl</kbd> : Traversing text with as usual on Windows * <kbd>Ctrl</kbd> + <kbd>R</kbd> : History search * <kbd>Shift</kbd> + Mouse : Select and copy text from buffer _(Some shortcuts are not yet documented, though they exist - please document them here)_ ## Features ### Access to multiple shells in one window using tabs You can open multiple tabs each containing one of the following shells: | Task | Shell | Description | | ---- | ----- | ----------- | | Cmder | `cmd.exe` | Windows `cmd.exe` shell enhanced with Git, Git aware prompt, Clink (GNU Readline), and Aliases. | | Cmder as Admin | `cmd.exe` | Administrative Windows `cmd.exe` Cmder shell. | | PowerShell | `powershell.exe` | Windows PowerShell enhanced with Git and Git aware prompt . | | PowerShell as Admin | `powershell.exe` | Administrative Windows `powershell.exe` Cmder shell. | | Bash | `bash.exe` | Unix/Linux like bash shell running on Windows. | | Bash as Admin | `bash.exe` | Administrative Unix/Linux like bash shell running on Windows. | | Mintty | `bash.exe` | Unix/Linux like bash shell running on Windows. See below for Mintty configuration differences | | Mintty as Admin | `bash.exe` | Administrative Unix/Linux like bash shell running on Windows. See below for Mintty configuration differences | Cmder, PowerShell, and Bash tabs all run on top of the Windows Console API and work as you might expect in Cmder with access to use ConEmu's color schemes, key bindings and other settings defined in the ConEmu Settings dialog. ⚠ *NOTE:* Only the full edition of Cmder comes with a pre-installed bash, using a vendored [git-for-windows](https://gitforwindows.org/) installation. The pre-configured Bash tabs may not work on Cmder mini edition without additional configuration. You may however, choose to use an external installation of bash, such as Microsoft's [Subsystem for Linux](https://docs.microsoft.com/en-us/windows/wsl/install-win10) (called WSL) or the [Cygwin](https://cygwin.com/) project which provides POSIX support on windows. ⚠ *NOTE:* Mintty tabs use a program called 'mintty' as the terminal emulator that is not based on the Windows Console API, rather it's rendered graphically by ConEmu. Mintty differs from the other tabs in that it supports xterm/xterm-256color TERM types, and does not work with ConEmu settings like color schemes and key bindings. As such, some differences in functionality are to be expected, such as Cmder not being able to apply a system-wide configuration to it. As a result mintty specific config is done via the `[%USERPROFILE%|$HOME]/.minttyrc` file. You may read more about Mintty and its config file [here](https://github.com/mintty/mintty). An example of setting Cmder portable terminal colors for mintty: From a bash/mintty shell: ``` cd $CMDER_ROOT/vendor git clone https://github.com/karlin/mintty-colors-solarized.git cd mintty-colors-solarized/ echo source \$CMDER_ROOT/vendor/mintty-colors-solarized/mintty-solarized-dark.sh>>$CMDER_ROOT/config/user_profile.sh ``` You may find some Monokai color schemes for mintty to match Cmder [here](https://github.com/oumu/mintty-color-schemes/blob/master/base16-monokai-mod.minttyrc). ### Changing Cmder Default `cmd.exe` Prompt Config File The default Cmder shell `cmd::Cmder` prompt is customized using `Clink` and is configured by editing a config file that exists in one of two locations: - Single User Portable Config `%CMDER_ROOT%\config\cmder_prompt_config.lua` - Shared Cmder install with Non-Portable Individual User Config `%CMDER_USER_CONFIG%\cmder_prompt_config.lua` If your Cmder setup does not have this file create it from `%CMDER_ROOT%\vendor\cmder_prompt_config.lua.default` Customizations include: - Colors. - Single/Multi-line. - Full path/Folder only. - `[user]@[host]` to the beginning of the prompt. - `~` for home directory. - `λ` symbol Documentation is in the file for each setting. ### Changing Cmder Default `cmd.exe` Shell Startup Behaviour Using Task Arguments 1. Press <kbd>Win</kbd> + <kbd>Alt</kbd> + <kbd>T</kbd> 1. Click either: * `1. {cmd::Cmder as Admin}` * `2. {cmd::Cmder}` 1. Add command line arguments where specified below: *Note: Pay attention to the quotes!* ``` cmd /s /k ""%ConEmuDir%\..\init.bat" [ADD ARGS HERE]" ``` ##### Command Line Arguments for `init.bat` | Argument | Description | Default | | ----------------------------- | ---------------------------------------------------------------------------------------------- | ------------------------------------- | | `/c [user cmder root]` | Enables user bin and config folders for 'Cmder as admin' sessions due to non-shared environment. | not set | | `/d` | Enables debug output. | not set | | `/f` | Enables Cmder Fast Init Mode. This disables some features, see pull request [#1492](https://github.com/cmderdev/cmder/pull/1942) for more details. | not set | | `/t` | Enables Cmder Timed Init Mode. This displays the time taken run init scripts | not set | | `/git_install_root [file path]` | User specified Git installation root path. | `%CMDER_ROOT%\vendor\Git-for-Windows` | | `/home [home folder]` | User specified folder path to set `%HOME%` environment variable. | `%userprofile%` | | `/max_depth [1-5]` | Define max recurse depth when adding to the path for `%cmder_root%\bin` and `%cmder_user_bin%` | 1 | | `/nix_tools [0-2]` | Define how `*nix` tools are added to the path. Prefer Windows Tools: 1, Prefer *nix Tools: 2, No `/usr/bin` in `%PATH%`: 0 | 1 | | `/svn_ssh [path to ssh.exe]` | Define `%SVN_SSH%` so we can use git svn with ssh svn repositories. | `%GIT_INSTALL_ROOT%\bin\ssh.exe` | | `/user_aliases [file path]` | File path pointing to user aliases. | `%CMDER_ROOT%\config\user_aliases.cmd` | | `/v` | Enables verbose output. | not set | | (custom arguments) | User defined arguments processed by `cexec`. Type `cexec /?` for more usage. | not set | ### Cmder Shell User Config Single user portable configuration is possible using the cmder specific shell config files. Edit the below files to add your own configuration: | Shell | Cmder Portable User Config | | ------------- | ----------------------------------------- | | Cmder | `%CMDER_ROOT%\config\user_profile.cmd` | | PowerShell | `$ENV:CMDER_ROOT\config\user_profile.ps1` | | Bash/Mintty | `$CMDER_ROOT/config/user_profile.sh` | Note: Bash and Mintty sessions will also source the `$HOME/.bashrc` file if it exists after it sources `$CMDER_ROOT/config/user_profile.sh`. You can write `*.cmd|*.bat`, `*.ps1`, and `*.sh` scripts and just drop them in the `%CMDER_ROOT%\config\profile.d` folder to add startup config to Cmder. | Shell | Cmder `Profile.d` Scripts | | ------------- | -------------------------------------------------- | | Cmder | `%CMDER_ROOT%\config\profile.d\*.bat and *.cmd` | | PowerShell | `$ENV:CMDER_ROOT\config\profile.d\*.ps1` | | Bash/Mintty | `$CMDER_ROOT/config/profile.d/*.sh` | #### Git Status Opt-Out To disable Cmder prompt git status globally add the following to `~/.gitconfig` or locally for a single repo `[repo]/.git/config` and start a new session. *Note: This configuration is not portable* ``` [cmder] status = false # Opt out of Git status for 'ALL' Cmder supported shells. cmdstatus = false # Opt out of Git status for 'Cmd.exe' shells. psstatus = false # Opt out of Git status for 'Powershell.exe and 'Pwsh.exe' shells. shstatus = false # Opt out of Git status for 'bash.exe' shells. ``` ### Aliases #### Cmder(`Cmd.exe`) Aliases You can define simple aliases for `cmd.exe` sessions with a command like `alias name=command`. Cmd.exe aliases support optional parameters through the `$1-9` or the `$*` special characters so the alias `vi=vim.exe $*` typed as `vi [filename]` will open `[filename]` in `vim.exe`. Cmd.exe aliases can also be more complex. See: [DOSKEY.EXE documentation](https://docs.microsoft.com/en-us/windows-server/administration/windows-commands/doskey) for additional details on complex aliases/macros for `cmd.exe` Aliases defined using the `alias.bat` command will automatically be saved in the `%CMDER_ROOT%\config\user_aliases.cmd` file To make an alias and/or any other profile settings permanent add it to one of the following: Note: These are loaded in this order by `$CMDER_ROOT/vendor/init.bat`. Anything stored in `%CMDER_ROOT%` will be a portable setting and will follow cmder to another machine. * `%CMDER_ROOT%\config\profile.d\*.cmd` and `\*.bat` * `%CMDER_ROOT%\config\user_aliases.cmd` * `%CMDER_ROOT%\config\user_profile.cmd` #### Bash.exe|Mintty.exe Aliases Bash shells support simple and complex aliases with optional parameters natively so they work a little different. Typing `alias name=command` will create an alias only for the current running session. To make an alias and/or any other profile settings permanent add it to one of the following: Note: These are loaded in this order by `$CMDER_ROOT/vendor/git-for-windows/etc/profile.d/cmder.sh`. Anything stored in `$CMDER_ROOT` will be a portable setting and will follow cmder to another machine. * `$CMDER_ROOT/config/profile.d/*.sh` * `$CMDER_ROOT/config/user_profile.sh` * `$HOME/.bashrc` If you add bash aliases to `$CMDER_ROOT/config/user_profile.sh` they will be portable and follow your Cmder folder if you copy it to another machine. `$HOME/.bashrc` defined aliases are not portable. #### PowerShell.exe Aliases PowerShell has native simple alias support, for example `[new-alias | set-alias] alias command`, so complex aliases with optional parameters are not supported in PowerShell sessions. Type `get-help [new-alias|set-alias] -full` for help on PowerShell aliases. To make an alias and/or any other profile settings permanent add it to one of the following: Note: These are loaded in this order by `$ENV:CMDER_ROOT\vendor\user_profile.ps1`. Anything stored in `$ENV:CMDER_ROOT` will be a portable setting and will follow cmder to another machine. * `$ENV:CMDER_ROOT\config\profile.d\*.ps1` * `$ENV:CMDER_ROOT\config\user_profile.ps1` ### SSH Agent To start the vendored SSH agent simply call `start-ssh-agent`, which is in the `vendor/git-for-windows/cmd` folder. If you want to run SSH agent on startup, include the line `@call "%GIT_INSTALL_ROOT%/cmd/start-ssh-agent.cmd"` in `%CMDER_ROOT%/config/user_profile.cmd` (usually just uncomment it). ### Vendored Git Cmder is by default shipped with a vendored Git installation. On each instance of launching Cmder, an attempt is made to locate any other user provided Git binaries. Upon finding a `git.exe` binary, Cmder further compares its version against the vendored one _by executing_ it. The vendored `git.exe` binary is _only_ used when it is more recent than the user-installed one. You may use your favorite version of Git by including its path in the `%PATH%` environment variable. Moreover, the **Mini** edition of Cmder (found on the [downloads page](https://github.com/cmderdev/cmder/releases)) excludes any vendored Git binaries. ### Using external Cygwin/Babun, MSys2, WSL, or Git for Windows SDK with Cmder. You may run bash (the default shell used on Linux, macOS and GNU/Hurd) externally on Cmder, using the following instructions: 1. Setup a new task by pressing <kbd>Win</kbd> +<kbd>Alt</kbd> + <kbd>T</kbd>. 1. Click the `+` button to add a task. 1. Name the new task in the top text box. 1. Provide task parameters, this is optional. 1. Add `cmd /c "[path_to_external_env]\bin\bash --login -i" -new_console` to the `Commands` text box. **Recommended Optional Steps:** Copy the `vendor/cmder_exinit` file to the Cygwin/Babun, MSys2, or Git for Windows SDK environments `/etc/profile.d/` folder to use portable settings in the `$CMDER_ROOT/config` folder. Note: MinGW could work if the init scripts include `profile.d` but this has not been tested. The destination file extension depends on the shell you use in that environment. For example: * bash - Copy to `/etc/profile.d/cmder_exinit.sh` * zsh - Copy to `/etc/profile.d/cmder_exinit.zsh` Uncomment and edit the below line in the script to use Cmder config even when launched from outside Cmder. ``` # CMDER_ROOT=${USERPROFILE}/cmder # This is not required if launched from Cmder. ``` ### Customizing user sessions using `init.bat` custom arguments. You can pass custom arguments to `init.bat` and use `cexec.cmd` in your `user_profile.cmd` to evaluate these arguments then execute commands based on a particular flag being detected or not. `init.bat` creates two shortcuts for using `cexec.cmd` in your profile scripts. #### `%ccall%` - Evaluates flags, runs commands if found, and returns to the calling script and continues. ``` ccall=call C:\Users\user\cmderdev\vendor\bin\cexec.cmd ``` Example: `%ccall% /startnotepad start notepad.exe` #### `%cexec%` - Evaluates flags, runs commands if found, and does not return to the calling script. ``` cexec=C:\Users\user\cmderdev\vendor\bin\cexec.cmd ``` Example: `%cexec% /startnotepad start notepad.exe` It is useful when you have multiple tasks to execute `cmder` and need it to initialize the session differently depending on the task chosen. To conditionally start `notepad.exe` when you start a specific `cmder` task: * Press <kbd>win</kbd>+<kbd>alt</kbd>+<kbd>t</kbd> * Click `+` to add a new task. * Add the below to the `Commands` block: ```batch cmd.exe /k ""%ConEmuDir%\..\init.bat" /startnotepad" ``` * Add the below to your `%cmder_root%\config\user_profile.cmd` ```batch %ccall% "/startNotepad" "start" "notepad.exe"` ``` To see detailed usage of `cexec`, type `cexec /?` in cmder. ### Integrating Cmder with [Hyper](https://github.com/zeit/hyper), [Microsoft VS Code](https://code.visualstudio.com/), and your favorite IDEs Cmder by default comes with a vendored ConEmu installation as the underlying terminal emulator, as stated [here](https://conemu.github.io/en/cmder.html). However, Cmder can in fact run in a variety of other terminal emulators, and even integrated IDEs. Assuming you have the latest version of Cmder, follow the following instructions to get Cmder working with your own terminal emulator. For instructions on how to integrate Cmder with your IDE, please read our [Wiki section](https://github.com/cmderdev/cmder/wiki#cmder-integration). ## Upgrading The process of upgrading Cmder depends on the version/build you are currently running. If you have a `[cmder_root]/config/user[-|_]conemu.xml`, you are running a newer version of Cmder, follow the below process: 1. Exit all Cmder sessions and relaunch `[cmder_root]/cmder.exe`, this backs up your existing `[cmder_root]/vendor/conemu-maximus5/conemu.xml` to `[cmder_root]/config/user[-|_]conemu.xml`. * The `[cmder_root]/config/user[-|_]conemu.xml` contains any custom settings you have made using the 'Setup Tasks' settings dialog. 2. Exit all Cmder sessions and backup any files you have manually edited under `[cmder_root]/vendor`. * Editing files under `[cmder_root]/vendor` is not recommended since you will need to re-apply these changes after any upgrade. All user customizations should go in `[cmder_root]/config` folder. 3. Delete the `[cmder_root]/vendor` folder. 4. Extract the new `cmder.zip` or `cmder_mini.zip` into `[cmder_root]/` overwriting all files when prompted. If you do not have a `[cmder_root]/config/user[-|_]conemu.xml`, you are running an older version of cmder, follow the below process: 1. Exit all Cmder sessions and backup `[cmder_root]/vendor/conemu-maximus5/conemu.xml` to `[cmder_root]/config/user[-|_]conemu.xml`. 2. Backup any files you have manually edited under `[cmder_root]/vendor`. * Editing files under `[cmder_root]/vendor` is not recommended since you will need to re-apply these changes after any upgrade. All user customizations should go in `[cmder_root]/config` folder. 3. Delete the `[cmder_root]/vendor` folder. 4. Extract the new `cmder.zip` or `cmder_mini.zip` into `[cmder_root]/` overwriting all files when prompted. ## Current development builds You can download builds of the current development branch by going to AppVeyor via the following link: [](https://ci.appveyor.com/project/MartiUK/cmder/branch/master/artifacts) ## License All software included is bundled with own license The MIT License (MIT) Copyright (c) 2016 Samuel Vasko Permission is hereby granted, free of charge, to any person obtaining a copy of this software and associated documentation files (the "Software"), to deal in the Software without restriction, including without limitation the rights to use, copy, modify, merge, publish, distribute, sublicense, and/or sell copies of the Software, and to permit persons to whom the Software is furnished to do so, subject to the following conditions: The above copyright notice and this permission notice shall be included in all copies or substantial portions of the Software.

lhai36366 / Lhai36366WPF Partial Trust Security Article 10 minutes to read In general, Internet applications should be restricted from having direct access to critical system resources, to prevent malicious damage. By default, HTML and client-side scripting languages are not able to access critical system resources. Because Windows Presentation Foundation (WPF) browser-hosted applications can be launched from the browser, they should conform to a similar set of restrictions. To enforce these restrictions, WPF relies on both Code Access Security (CAS) and ClickOnce (see WPF Security Strategy - Platform Security). By default, browser-hosted applications request the Internet zone CAS set of permissions, irrespective of whether they are launched from the Internet, the local intranet, or the local computer. Applications that run with anything less than the full set of permissions are said to be running with partial trust. WPF provides a wide variety of support to ensure that as much functionality as possible can be used safely in partial trust, and along with CAS, provides additional support for partial trust programming. This topic contains the following sections: WPF Feature Partial Trust Support Partial Trust Programming Managing Permissions WPF Feature Partial Trust Support The following table lists the high-level features of Windows Presentation Foundation (WPF) that are safe to use within the limits of the Internet zone permission set. Table 1: WPF Features that are Safe in Partial Trust Feature Area Feature General Browser Window Site of Origin Access IsolatedStorage (512KB Limit) UIAutomation Providers Commanding Input Method Editors (IMEs) Tablet Stylus and Ink Simulated Drag/Drop using Mouse Capture and Move Events OpenFileDialog XAML Deserialization (via XamlReader.Load) Web Integration Browser Download Dialog Top-Level User-Initiated Navigation mailto:links Uniform Resource Identifier Parameters HTTPWebRequest WPF Content Hosted in an IFRAME Hosting of Same-Site HTML Pages using Frame Hosting of Same Site HTML Pages using WebBrowser Web Services (ASMX) Web Services (using Windows Communication Foundation) Scripting Document Object Model Visuals 2D and 3D Animation Media (Site Of Origin and Cross-Domain) Imaging/Audio/Video Reading FlowDocuments XPS Documents Embedded & System Fonts CFF & TrueType Fonts Editing Spell Checking RichTextBox Plaintext and Ink Clipboard Support User-Initiated Paste Copying Selected Content Controls General Controls This table covers the WPF features at a high level. For more detailed information, the Windows Software Development Kit (SDK) documents the permissions that are required by each member in WPF. Additionally, the following features have more detailed information regarding partial trust execution, including special considerations. XAML (see XAML Overview (WPF)). Popups (see System.Windows.Controls.Primitives.Popup). Drag and Drop (see Drag and Drop Overview). Clipboard (see System.Windows.Clipboard). Imaging (see System.Windows.Controls.Image). Serialization (see XamlReader.Load, XamlWriter.Save). Open File Dialog Box (see Microsoft.Win32.OpenFileDialog). The following table outlines the WPF features that are not safe to run within the limits of the Internet zone permission set. Table 2: WPF Features that are Not Safe in Partial Trust Feature Area Feature General Window (Application Defined Windows and Dialog Boxes) SaveFileDialog File System Registry Access Drag and Drop XAML Serialization (via XamlWriter.Save) UIAutomation Clients Source Window Access (HwndHost) Full Speech Support Windows Forms Interoperability Visuals Bitmap Effects Image Encoding Editing Rich Text Format Clipboard Full XAML support Partial Trust Programming For XBAP applications, code that exceeds the default permission set will have different behavior depending on the security zone. In some cases, the user will receive a warning when they attempt to install it. The user can choose to continue or cancel the installation. The following table describes the behavior of the application for each security zone and what you have to do for the application to receive full trust. Security Zone Behavior Getting Full Trust Local computer Automatic full trust No action is needed. Intranet and trusted sites Prompt for full trust Sign the XBAP with a certificate so that the user sees the source in the prompt. Internet Fails with "Trust Not Granted" Sign the XBAP with a certificate. Note The behavior described in the previous table is for full trust XBAPs that do not follow the ClickOnce Trusted Deployment model. In general, code that may exceed the allowed permissions is likely to be common code that is shared between both standalone and browser-hosted applications. CAS and WPF offer several techniques for managing this scenario. Detecting Permissions Using CAS In some situations, it is possible for shared code in library assemblies to be used by both standalone applications and XBAPs. In these cases, code may execute functionality that could require more permissions than the application's awarded permission set allows. Your application can detect whether or not it has a certain permission by using Microsoft .NET Framework security. Specifically, it can test whether it has a specific permission by calling the Demand method on the instance of the desired permission. This is shown in the following example, which has code that queries for whether it has the ability to save a file to the local disk: Imports System.IO ' File, FileStream, StreamWriter Imports System.IO.IsolatedStorage ' IsolatedStorageFile Imports System.Security ' CodeAccesPermission, IsolatedStorageFileStream Imports System.Security.Permissions ' FileIOPermission, FileIOPermissionAccess Imports System.Windows ' MessageBox Namespace SDKSample Public Class FileHandling Public Sub Save() If IsPermissionGranted(New FileIOPermission(FileIOPermissionAccess.Write, "c:\newfile.txt")) Then ' Write to local disk Using stream As FileStream = File.Create("c:\newfile.txt") Using writer As New StreamWriter(stream) writer.WriteLine("I can write to local disk.") End Using End Using Else MessageBox.Show("I can't write to local disk.") End If End Sub ' Detect whether or not this application has the requested permission Private Function IsPermissionGranted(ByVal requestedPermission As CodeAccessPermission) As Boolean Try ' Try and get this permission requestedPermission.Demand() Return True Catch Return False End Try End Function ... End Class End Namespace using System.IO; // File, FileStream, StreamWriter using System.IO.IsolatedStorage; // IsolatedStorageFile using System.Security; // CodeAccesPermission, IsolatedStorageFileStream using System.Security.Permissions; // FileIOPermission, FileIOPermissionAccess using System.Windows; // MessageBox namespace SDKSample { public class FileHandling { public void Save() { if (IsPermissionGranted(new FileIOPermission(FileIOPermissionAccess.Write, @"c:\newfile.txt"))) { // Write to local disk using (FileStream stream = File.Create(@"c:\newfile.txt")) using (StreamWriter writer = new StreamWriter(stream)) { writer.WriteLine("I can write to local disk."); } } else { MessageBox.Show("I can't write to local disk."); } } // Detect whether or not this application has the requested permission bool IsPermissionGranted(CodeAccessPermission requestedPermission) { try { // Try and get this permission requestedPermission.Demand(); return true; } catch { return false; } } ... } } If an application does not have the desired permission, the call to Demand will throw a security exception. Otherwise, the permission has been granted. IsPermissionGranted encapsulates this behavior and returns true or false as appropriate. Graceful Degradation of Functionality Being able to detect whether code has the permission to do what it needs to do is interesting for code that can be executed from different zones. While detecting the zone is one thing, it is far better to provide an alternative for the user, if possible. For example, a full trust application typically enables users to create files anywhere they want, while a partial trust application can only create files in isolated storage. If the code to create a file exists in an assembly that is shared by both full trust (standalone) applications and partial trust (browser-hosted) applications, and both applications want users to be able to create files, the shared code should detect whether it is running in partial or full trust before creating a file in the appropriate location. The following code demonstrates both. Imports System.IO ' File, FileStream, StreamWriter Imports System.IO.IsolatedStorage ' IsolatedStorageFile Imports System.Security ' CodeAccesPermission Imports System.Security.Permissions ' FileIOPermission, FileIOPermissionAccess Imports System.Windows ' MessageBox Namespace SDKSample Public Class FileHandlingGraceful Public Sub Save() If IsPermissionGranted(New FileIOPermission(FileIOPermissionAccess.Write, "c:\newfile.txt")) Then ' Write to local disk Using stream As FileStream =tênthietbi:<hailuu(GT-19195)>phienban.android<4.4.2>capdovaloibaomat<2016-05-01>phienban.baseband<19195xxscQA3> File.Create("c:\newfile.txt") Using writer As New StreamWriter(stream) writer.WriteLine("I can write to local disk.")

In a controlled environment, such as an intranet, custom managed frameworks can be installed across the client base into the global assembly cache (GAC). These libraries can execute code that requires full trust, and be referenced from applications that are only allowed partial trust by using AllowPartiallyTrustedCallersAttribute (for more information, see Security (WPF) and WPF Security Strategy - Platform Security). Browser Host Detection Using CAS to check for permissions is a suitable technique when you need to check on a per-permission basis. Although, this technique depends on catching exceptions as a part of normal processing, which is not recommended in general and can have performance issues. Instead, if your XAML browser application (XBAP) only runs within the Internet zone sandbox, you can use the BrowserInteropHelper.IsBrowserHosted property, which returns true for XAML browser applications (XBAPs). Note IsBrowserHosted only distinguishes whether an application is running in a browser, not which set of permissions an application is running with. Managing Permissions By default, XBAPs run with partial trust (default Internet zone permission set). However, depending on the requirements of the application, it is possible to change the set of permissions from the default. For example, if an XBAPs is launched from a local intranet, it can take advantage of an increased permission set, which is shown in the following table. Table 3: LocalIntranet and Internet Permissions Permission Attribute LocalIntranet Internet DNS Access DNS servers Yes No Environment Variables Read Yes No File Dialogs Open Yes Yes File Dialogs Unrestricted Yes No Isolated Storage Assembly isolation by user Yes No Isolated Storage Unknown isolation Yes Yes Isolated Storage Unlimited user quota Yes No Media Safe audio, video, and images Yes Yes Printing Default printing Yes No Printing Safe printing Yes Yes Reflection Emit Yes No Security Managed code execution Yes Yes Security Assert granted permissions Yes No User Interface Unrestricted Yes No User Interface Safe top level windows Yes Yes User Interface Own Clipboard Yes Yes Web Browser Safe frame navigation to HTML Yes Yes Note Cut and Paste is only allowed in partial trust when user initiated. If you need to increase permissions, you need to change the project settings and the ClickOnce application manifest. For more information, see WPF XAML Browser Applications Overview. The following documents may also be helpful. Mage.exe (Manifest Generation and Editing Tool). MageUI.exe (Manifest Generation and Editing Tool, Graphical Client). Securing ClickOnce Applications. If your XBAP requires full trust, you can use the same tools to increase the requested permissions. Although an XBAP will only receive full trust if it is installed on and launched from the local computer, the intranet, or from a URL that is listed in the browser's trusted or allowed sites. If the application is installed from the intranet or a trusted site, the user will receive the standard ClickOnce prompt notifying them of the elevated permissions. The user can choose to continue or cancel the installation. Alternatively, you can use the ClickOnce Trusted Deployment model for full trust deployment from any security zone.

SOYJUN / Implement ODR ProtocolOverview For this assignment you will be developing and implementing : An On-Demand shortest-hop Routing (ODR) protocol for networks of fixed but arbitrary and unknown connectivity, using PF_PACKET sockets. The implementation is based on (a simplified version of) the AODV algorithm. Time client and server applications that send requests and replies to each other across the network using ODR. An API you will implement using Unix domain datagram sockets enables applications to communicate with the ODR mechanism running locally at their nodes. I shall be discussing the assignment in class on Wednesday, October 29, and Monday, November 3. The following should prove useful reference material for the assignment : Sections 15.1, 15.2, 15.4 & 15.6, Chapter 15, on Unix domain datagram sockets. PF_PACKET(7) from the Linux manual pages. You might find these notes made by a past CSE 533 student useful. Also, the following link http://www.pdbuchan.com/rawsock/rawsock.html contains useful code samples that use PF_PACKET sockets (as well as other code samples that use raw IP sockets which you do not need for this assignment, though you will be using these types of sockets for Assignment 4). Charles E. Perkins & Elizabeth M. Royer. “Ad-hoc On-Demand Distance Vector Routing.” Proceedings of the 2nd IEEE Workshop on Mobile Computing Systems and Applications, New Orleans, Louisiana, February 1999, pp. 90 - 100. The VMware environment minix.cs.stonybrook.edu is a Linux box running VMware. A cluster of ten Linux virtual machines, called vm1 through vm10, on which you can gain access as root and run your code have been created on minix. See VMware Environment Hosts for further details. VMware instructions takes you to a page that explains how to use the system. The ten virtual machines have been configured into a small virtual intranet of Ethernet LANs whose topology is (in principle) unknown to you. There is a course account cse533 on node minix, with home directory /users/cse533. In there, you will find a subdirectory Stevens/unpv13e , exactly as you are used to having on the cs system. You should develop your source code and makefiles for handing in accordingly. You will be handing in your source code on the minix node. Note that you do not need to link against the socket library (-lsocket) in Linux. The same is true for -lnsl and -lresolv. For example, take a look at how the LIBS variable is defined for Solaris, in /home/courses/cse533/Stevens/unpv13e_solaris2.10/Make.defines (on compserv1, say) : LIBS = ../libunp.a -lresolv -lsocket -lnsl -lpthread But if you take a look at Make.defines on minix (/users/cse533/Stevens/unpv13e/Make.defines) you will find only: LIBS = ../libunp.a -lpthread The nodes vm1 , . . . . . , vm10 are all multihomed : each has two (or more) interfaces. The interface ‘eth0 ’ should be completely ignored and is not to be used for this assignment (because it shows all ten nodes as if belonging to the same single Ethernet 192.168.1.0/24, rather than to an intranet composed of several Ethernets). Note that vm1 , . . . . . , vm10 are virtual machines, not real ones. One implication of this is that you will not be able to find out what their (virtual) IP addresses are by using nslookup and such. To find out these IP addresses, you need to look at the file /etc/hosts on minix. More to the point, invoking gethostbyname for a given vm will return to you only the (primary) IP address associated with the interface eth0 of that vm (which is the interface you will not be using). It will not return to you any other IP address for the node. Similarly, gethostbyaddr will return the vm node name only if you give it the (primary) IP address associated with the interface eth0 for the node. It will return nothing if you give it any other IP address for the node, even though the address is perfectly valid. Because of this, and because it will ease your task to be able to use gethostbyname and gethostbyaddr in a straightforward way, we shall adopt the (primary) IP addresses associated with interfaces eth0 as the ‘canonical’ IP addresses for the nodes (more on this below). Time client and server A time server runs on each of the ten vm machines. The client code should also be available on each vm so that it can be evoked at any of them. Normally, time clients/servers exchange request/reply messages using the TCP/UDP socket API that, effectively, enables them to receive service (indirectly, via the transport layer) from the local IP mechanism running at their nodes. You are to implement an API using Unix domain sockets to access the local ODR service directly (somewhat similar, in effect, to the way that raw sockets permit an application to access IP directly). Use Unix domain SOCK_DGRAM, rather than SOCK_STREAM, sockets (see Figures 15.5 & 15.6, pp. 418 - 419). API You need to implement a msg_send function that will be called by clients/servers to send requests/replies. The parameters of the function consist of : int giving the socket descriptor for write char* giving the ‘canonical’ IP address for the destination node, in presentation format int giving the destination ‘port’ number char* giving message to be sent int flag if set, force a route rediscovery to the destination node even if a non-‘stale’ route already exists (see below) msg_send will format these parameters into a single char sequence which is written to the Unix domain socket that a client/server process creates. The sequence will be read by the local ODR from a Unix domain socket that the ODR process creates for itself. Recall that the ‘canonical’ IP address for a vm node is the (primary) IP address associated with the eth0 interface for the node. It is what will be returned to you by a call to gethostbyname. Similarly, we need a msg_recv function which will do a (blocking) read on the application domain socket and return with : int giving socket descriptor for read char* giving message received char* giving ‘canonical’ IP address for the source node of message, in presentation format int* giving source ‘port’ number This information is written as a single char sequence by the ODR process to the domain socket that it creates for itself. It is read by msg_recv from the domain socket the client/server process creates, decomposed into the three components above, and returned to the caller of msg_recv. Also see the section below entitled ODR and the API. Client When a client is evoked at a node, it creates a domain datagram socket. The client should bind its socket to a ‘temporary’ (i.e., not ‘well-known’) sun_path name obtained from a call to tmpnam() (cf. line 10, Figure 15.6, p. 419) so that multiple clients may run at the same node. Note that tmpnam() is actually highly deprecated. You should use the mkstemp() function instead - look up the online man pages on minix (‘man mkstemp’) for details. As you run client code again and again during the development stage, the temporary files created by the calls to tmpnam / mkstemp start to proliferate since these files are not automatically removed when the client code terminates. You need to explicitly remove the file created by the client evocation by issuing a call to unlink() or to remove() in your client code just before the client code exits. See the online man pages on minix (‘man unlink’, ‘man remove’) for details. The client then enters an infinite loop repeating the steps below. The client prompts the user to choose one of vm1 , . . . . . , vm10 as a server node. Client msg_sends a 1 or 2 byte message to server and prints out on stdout the message client at node vm i1 sending request to server at vm i2 (In general, throughout this assignment, “trace” messages such as the one above should give the vm names and not IP addresses of the nodes.) Client then blocks in msg_recv awaiting response. This attempt to read from the domain socket should be backed up by a timeout in case no response ever comes. I leave it up to you whether you ‘wrap’ the call to msg_recv in a timeout, or you implement the timeout inside msg_recv itself. When the client receives a response it prints out on stdout the message client at node vm i1 : received from vm i2 <timestamp> If, on the other hand, the client times out, it should print out the message client at node vm i1 : timeout on response from vm i2 The client then retransmits the message out, setting the flag parameter in msg_send to force a route rediscovery, and prints out an appropriate message on stdout. This is done only once, when a timeout for a given message to the server occurs for the first time. Client repeats steps 1. - 3. Server The server creates a domain datagram socket. The server socket is assumed to have a (node-local) ‘well-known’ sun_path name which it binds to. This ‘well-known’ sun_path name is designated by a (network-wide) ‘well-known’ ‘port’ value. The time client uses this ‘port’ value to communicate with the server. The server enters an infinite sequence of calls to msg_recv followed by msg_send, awaiting client requests and responding to them. When it responds to a client request, it prints out on stdout the message server at node vm i1 responding to request from vm i2 ODR The ODR process runs on each of the ten vm machines. It is evoked with a single command line argument which gives a “staleness” time parameter, in seconds. It uses get_hw_addrs (available to you on minix in ~cse533/Asgn3_code) to obtain the index, and associated (unicast) IP and Ethernet addresses for each of the node’s interfaces, except for the eth0 and lo (loopback) interfaces, which should be ignored. In the subdirectory ~cse533/Asgn3_code (/users/cse533/Asgn3_code) on minix I am providing you with two functions, get_hw_addrs and prhwaddrs. These are analogous to the get_ifi_info_plus and prifinfo_plus of Assignment 2. Like get_ifi_info_plus, get_hw_addrs uses ioctl. get_hw_addrs gets the (primary) IP address, alias IP addresses (if any), HW address, and interface name and index value for each of the node's interfaces (including the loopback interface lo). prhwaddrs prints that information out. You should modify and use these functions as needed. Note that if an interface has no HW address associated with it (this is, typically, the case for the loopback interface lo for example), then ioctl returns get_hw_addrs a HW address which is the equivalent of 00:00:00:00:00:00 . get_hw_addrs stores this in the appropriate field of its data structures as it would with any HW address returned by ioctl, but when prhwaddrs comes across such an address, it prints a blank line instead of its usual ‘HWaddr = xx:xx:xx:xx:xx:xx’. The ODR process creates one or more PF_PACKET sockets. You will need to try out PF_PACKET sockets for yourselves and familiarize yourselves with how they behave. If, when you read from the socket and provide a sockaddr_ll structure, the kernel returns to you the index of the interface on which the incoming frame was received, then one socket will be enough. Otherwise, somewhat in the manner of Assignment 2, you shall have to create a PF_PACKET socket for every interface of interest (which are all the interfaces of the node, excluding interfaces lo and eth0 ), and bind a socket to each interface. Furthermore, if the kernel also returns to you the source Ethernet address of the frame in the sockaddr_ll structure, then you can make do with SOCK_DGRAM type PF_PACKET sockets; otherwise you shall have to use SOCK_RAW type sockets (although I would prefer you to use SOCK_RAW type sockets anyway, even if it turns out you can make do with SOCK_DGRAM type). The socket(s) should have a protocol value (no larger than 0xffff so that it fits in two bytes; this value is given as a network-byte-order parameter in the call(s) to function socket) that identifies your ODR protocol. The <linux/if_ether.h> include file (i.e., the file /usr/include/linux/if_ether.h) contains protocol values defined for the standard protocols typically found on an Ethernet LAN, as well as other values such as ETH_P_ALL. You should set protocol to a value of your choice which is not a <linux/if_ether.h> value, but which is, hopefully, unique to yourself. Remember that you will all be running your code using the same root account on the vm1 , . . . . . , vm10 nodes. So if two of you happen to choose the same protocol value and happen to be running on the same vm node at the same time, your applications will receive each other’s frames. For that reason, try to choose a protocol value for the socket(s) that is likely to be unique to yourself (something based on your Stony Brook student ID number, for example). This value effectively becomes the protocol value for your implementation of ODR, as opposed to some other cse 533 student's implementation. Because your value of protocol is to be carried in the frame type field of the Ethernet frame header, the value chosen should be not less than 1536 (0x600) so that it is not misinterpreted as the length of an Ethernet 802.3 frame. Note from the man pages for packet(7) that frames are passed to and from the socket without any processing in the frame content by the device driver on the other side of the socket, except for calculating and tagging on the 4-byte CRC trailer for outgoing frames, and stripping that trailer before delivering incoming frames to the socket. Nevertheless, if you write a frame that is less than 60 bytes, the necessary padding is automatically added by the device driver so that the frame that is actually transmitted out is the minimum Ethernet size of 64 bytes. When reading from the socket, however, any such padding that was introduced into a short frame at the sending node to bring it up to the minimum frame size is not stripped off - it is included in what you receive from the socket (thus, the minimum number of bytes you receive should never be less than 60). Also, you will have to build the frame header for outgoing frames yourselves (assuming you use SOCK_RAW type sockets). Bear in mind that the field values in that header have to be in network order. The ODR process also creates a domain datagram socket for communication with application processes at the node, and binds the socket to a ‘well known’ sun_path name for the ODR service. Because it is dealing with fixed topologies, ODR is, by and large, considerably simpler than AODV. In particular, discovered routes are relatively stable and there is no need for all the paraphernalia that goes with the possibility of routes changing (such as maintenance of active nodes in the routing tables and timeout mechanisms; timeouts on reverse links; lifetime field in the RREP messages; etc.) Nor will we be implementing source_sequence_#s (in the RREQ messages), and dest_sequence_# (in RREQ and RREP messages). In reality, we should (though we will not, for the sake of simplicity, be doing so) implement some sort of sequence number mechanism, or some alternative mechanism such as split-horizon for example, if we are to avoid possible scenarios of routing loops in a “count to infinity” context (I shall explain this point in class). However, we want ODR to discover shortest-hop paths, and we want it to do so in a reasonably efficient manner. This necessitates having one or two aspects of its operations work in a different, possibly slightly more complicated, way than AODV does. ODR has several basic responsibilities : Build and maintain a routing table. For each destination in the table, the routing table structure should include, at a minimum, the next-hop node (in the form of the Ethernet address for that node) and outgoing interface index, the number of hops to the destination, and a timestamp of when the the routing table entry was made or last “reconfirmed” / updated. Note that a destination node in the table is to be identified only by its ‘canonical’ IP address, and not by any other IP addresses the node has. Generate a RREQ in response to a time client calling msg_send for a destination for which ODR has no route (or for which a route exists, but msg_send has the flag parameter set or the route has gone ‘stale’ – see below), and ‘flood’ the RREQ out on all the node’s interfaces (except for the interface it came in on and, of course, the interfaces eth0 and lo). Flooding is done using an Ethernet broadcast destination address (0xff:ff:ff:ff:ff:ff) in the outgoing frame header. Note that a copy of the broadcast packet is supposed to / might be looped back to the node that sends it (see p. 535 in the Stevens textbook). ODR will have to take care not to treat these copies as new incoming RREQs. Also note that ODR at the client node increments the broadcast_id every time it issues a new RREQ for any destination node. When a RREQ is received, ODR has to generate a RREP if it is at the destination node, or if it is at an intermediate node that happens to have a route (which is not ‘stale’ – see below) to the destination. Otherwise, it must propagate the RREQ by flooding it out on all the node’s interfaces (except the interface the RREQ arrived on). Note that as it processes received RREQs, ODR should enter the ‘reverse’ route back to the source node into its routing table, or update an existing entry back to the source node if the RREQ received shows a shorter-hop route, or a route with the same number of hops but going through a different neighbour. The timestamp associated with the table entry should be updated whenever an existing route is either “reconfirmed” or updated. Obviously, if the node is going to generate a RREP, updating an existing entry back to the source node with a more efficient route, or a same-hops route using a different neighbour, should be done before the RREP is generated. Unlike AODV, when an intermediate node receives a RREQ for which it generates a RREP, it should nevertheless continue to flood the RREQ it received if the RREQ pertains to a source node whose existence it has heretofore been unaware of, or the RREQ gives it a more efficient route than it knew of back to the source node (the reason for continuing to flood the RREQ is so that other nodes in the intranet also become aware of the existence of the source node or of the potentially more optimal reverse route to it, and update their tables accordingly). However, since an RREP for this RREQ is being sent by our node, we do not want other nodes who receive the RREQ propagated by our node, and who might be in a position to do so, to also send RREPs. So we need to introduce a field in the RREQ message, not present in the AODV specifications, which acts like a “RREP already sent” field. Our node sets this field before further propagating the RREQ and nodes receiving an RREQ with this field set do not send RREPs in response, even if they are in a position to do so. ODR may, of course, receive multiple, distinct instances of the same RREQ (the combination of source_addr and broadcast_id uniquely identifies the RREQ). Such RREQs should not be flooded out unless they have a lower hop count than instances of that RREQ that had previously been received. By the same token, if ODR is in a position to send out a RREP, and has already done so for this, now repeating, RREQ , it should not send out another RREP unless the RREQ shows a more efficient, previously unknown, reverse route back to the source node. In other words, ODR should not generate essentially duplicative RREPs, nor generate RREPs to instances of RREQs that reflect reverse routes to the source that are not more efficient than what we already have. Relay RREPs received back to the source node (this is done using the ‘reverse’ route entered into the routing table when the corresponding RREQ was processed). At the same time, a ‘forward’ path to the destination is entered into the routing table. ODR could receive multiple, distinct RREPs for the same RREQ. The ‘forward’ route entered in the routing table should be updated to reflect the shortest-hop route to the destination, and RREPs reflecting suboptimal routes should not be relayed back to the source. In general, maintaining a route and its associated timestamp in the table in response to RREPs received is done in the same manner described above for RREQs. Forward time client/server messages along the next hop. (The following is important – you will lose points if you do not implement it.) Note that such application payload messages (especially if they are the initial request from the client to the server, rather than the server response back to the client) can be like “free” RREPs, enabling nodes along the path from source (client) to destination (server) node to build a reverse path back to the client node whose existence they were heretofore unaware of (or, possibly, to update an existing route with a more optimal one). Before it forwards an application payload message along the next hop, ODR at an intermediate node (and also at the final destination node) should use the message to update its routing table in this way. Thus, calls to msg_send by time servers should never cause ODR at the server node to initiate RREQs, since the receipt of a time client request implies that a route back to the client node should now exist in the routing table. The only exception to this is if the server node has a staleness parameter of zero (see below). A routing table entry has associated with it a timestamp that gives the time the entry was made into the table. When a client at a node calls msg_send, and if an entry for the destination node already exists in the routing table, ODR first checks that the routing information is not ‘stale’. A stale routing table entry is one that is older than the value defined by the staleness parameter given as a command line argument to the ODR process when it is executed. ODR deletes stale entries (as well as non-stale entries when the flag parameter in msg_send is set) and initiates a route rediscovery by issuing a RREQ for the destination node. This will force periodic updating of the routing tables to take care of failed nodes along the current path, Ethernet addresses that might have changed, and so on. Similarly, as RREQs propagate through the intranet, existing stale table entries at intermediate nodes are deleted and new route discoveries propagated. As noted above when discussing the processing of RREQs and RREPs, the associated timestamp for an existing table entry is updated in response to having the route either “reconfirmed” or updated (this applies to both reverse routes, by virtue of RREQs received, and to forward routes, by virtue of RREPs). Finally, note that a staleness parameter of 0 essentially indicates that the discovered route will be used only once, when first discovered, and then discarded. Effectively, an ODR with staleness parameter 0 maintains no real routing table at all ; instead, it forces route discoveries at every step of its operation. As a practical matter, ODR should be run with staleness parameter values that are considerably larger than the longest RTT on the intranet, otherwise performance will degrade considerably (and collapse entirely as the parameter values approach 0). Nevertheless, for robustness, we need to implement a mechanism by which an intermediate node that receives a RREP or application payload message for forwarding and finds that its relevant routing table entry has since gone stale, can intiate a RREQ to rediscover the route it needs. RREQ, RREP, and time client/server request/response messages will all have to be carried as encapsulated ODR protocol messages that form the data payload of Ethernet frames. So we need to design the structure of ODR protocol messages. The format should contain a type field (0 for RREQ, 1 for RREP, 2 for application payload ). The remaining fields in an ODR message will depend on what type it is. The fields needed for (our simplified versions of AODV’s) RREQ and RREP should be fairly clear to you, but keep in mind that you need to introduce two extra fields: The “RREP already sent” bit or field in RREQ messages, as mentioned above. A “forced discovery” bit or field in both RREQ and RREP messages: When a client application forces route rediscovery, this bit should be set in the RREQ issued by the client node ODR. Intermediate nodes that are not the destination node but which do have a route to the destination node should not respond with RREPs to an RREQ which has the forced discovery field set. Instead, they should continue to flood the RREQ so that it eventually reaches the destination node which will then respond with an RREP. The intermediate nodes relaying such an RREQ must update their ‘reverse’ route back to the source node accordingly, even if the new route is less efficient (i.e., has more hops) than the one they currently have in their routing table. The destination node responds to the RREQ with an RREP in which this field is also set. Intermediate nodes that receive such a forced discovery RREP must update their ‘forward’ route to the destination node accordingly, even if the new route is less efficient (i.e., has more hops) than the one they currently have in their routing table. This behaviour will cause a forced discovery RREQ to be responded to only by the destination node itself and not any other node, and will cause intermediate nodes to update their routing tables to both source and destination nodes in accordance with the latest routing information received, to cover the possibility that older routes are no longer valid because nodes and/or links along their paths have gone down. A type 2, application payload, message needs to contain the following type of information : type = 2 ‘canonical’ IP address of source node ‘port’ number of source application process (This, of course, is not a real port number in the TCP/UDP sense, but simply a value that ODR at the source node uses to designate the sun_path name for the source application’s domain socket.) ‘canonical’ IP address of destination node ‘port’ number of destination application process (This is passed to ODR by the application process at the source node when it calls msg_send. Its designates the sun_path name for an application’s domain socket at the destination node.) hop count (This starts at 0 and is incremented by 1 at each hop so that ODR can make use of the message to update its routing table, as discussed above.) number of bytes in application message The fields above essentially constitute a ‘header’ for the ODR message. Note that fields which you choose to have carry numeric values (rather than ascii characters, for example) must be in network byte order. ODR-defined numeric-valued fields in type 0, RREQ, and type 1, RREP, messages must, of course, also be in network byte order. Also note that only the ‘canonical’ IP addresses are used for the source and destination nodes in the ODR header. The same has to be true in the headers for type 0, RREQ, and type 1, RREP, messages. The general rule is that ODR messages only carry ‘canonical’ IP node addresses. The last field in the type 2 ODR message is essentially the data payload of the message. application message given in the call to msg_send An ODR protocol message is encapsulated as the data payload of an Ethernet frame whose header it fills in as follows : source address = Ethernet address of outgoing interface of the current node where ODR is processing the message. destination address = Ethernet broadcast address for type 0 messages; Ethernet address of next hop node for type 1 & 2 messages. protocol field = protocol value for the ODR PF_PACKET socket(s). Last but not least, whenever ODR writes an Ethernet frame out through its socket, it prints out on stdout the message ODR at node vm i1 : sending frame hdr src vm i1 dest addr ODR msg type n src vm i2 dest vm i3 where addr is in presentation format (i.e., hexadecimal xx:xx:xx:xx:xx:xx) and gives the destination Ethernet address in the outgoing frame header. Other nodes in the message should be identified by their vm name. A message should be printed out for each packet sent out on a distinct interface. ODR and the API When the ODR process first starts, it must construct a table in which it enters all well-known ‘port’ numbers and their corresponding sun_path names. These will constitute permanent entries in the table. Thereafter, whenever it reads a message off its domain socket, it must obtain the sun_path name for the peer process socket and check whether that name is entered in the table. If not, it must select an ‘ephemeral’ ‘port’ value by which to designate the peer sun_path name and enter the pair < port value , sun_path name > into the table. Such entries cannot be permanent otherwise the table will grow unboundedly in time, with entries surviving for ever, beyond the peer processes’ demise. We must associate a time_to_live field with a non-permanent table entry, and purge the entry if nothing is heard from the peer for that amount of time. Every time a peer process for which a non-permanent table entry exists communicates with ODR, its time_to_live value should be reinitialized. Note that when ODR writes to a peer, it is possible for the write to fail because the peer does not exist : it could be a ‘well-known’ service that is not running, or we could be in the interval between a process with a non-permanent table entry terminating and the expiration of its time_to_live value. Notes A proper implementation of ODR would probably require that RREQ and RREP messages be backed up by some kind of timeout and retransmission mechanism since the network transmission environment is not reliable. This would considerably complicate the implementation (because at any given moment, a node could have multiple RREQs that it has flooded out, but for which it has still not received RREPs; the situation is further complicated by the fact that not all intermediate nodes receiving and relaying RREQs necessarily lie on a path to the destination, and therefore should expect to receive RREPs), and, learning-wise, would not add much to the experience you should have gained from Assignment 2.

ajaybhatiya1234 / DEEP FACE Dectection01 Read the technical deep dive: https://www.dessa.com/post/deepfake-detection-that-actually-works # Visual DeepFake Detection In our recent [article](https://www.dessa.com/post/deepfake-detection-that-actually-works), we make the following contributions: * We show that the model proposed in current state of the art in video manipulation (FaceForensics++) does not generalize to real-life videos randomly collected from Youtube. * We show the need for the detector to be constantly updated with real-world data, and propose an initial solution in hopes of solving deepfake video detection. Our Pytorch implementation, conducts extensive experiments to demonstrate that the datasets produced by Google and detailed in the FaceForensics++ paper are not sufficient for making neural networks generalize to detect real-life face manipulation techniques. It also provides a current solution for such behavior which relies on adding more data. Our Pytorch model is based on a pre-trained ResNet18 on Imagenet, that we finetune to solve the deepfake detection problem. We also conduct large scale experiments using Dessa's open source scheduler + experiment manger [Atlas](https://github.com/dessa-research/atlas). ## Setup ## Prerequisities To run the code, your system should meet the following requirements: RAM >= 32GB , GPUs >=1 ## Steps 0. Install [nvidia-docker](https://github.com/nvidia/nvidia-docker/wiki/Installation-(version-2.0)) 00. Install [ffmpeg](https://www.ffmpeg.org/download.html) or `sudo apt install ffmpeg` 1. Git Clone this repository. 2. If you haven't already, install [Atlas](https://github.com/dessa-research/atlas). 3. Once you've installed Atlas, activate your environment if you haven't already, and navigate to your project folder. That's it, You're ready to go! ## Datasets Half of the dataset used in this project is from the [FaceForensics](https://github.com/ondyari/FaceForensics/tree/master/dataset) deepfake detection dataset. . To download this data, please make sure to fill out the [google form](https://github.com/ondyari/FaceForensics/#access) to request access to the data. For the dataset that we collected from Youtube, it is accessible on [S3](ttps://deepfake-detection.s3.amazonaws.com/augment_deepfake.tar.gz) for download. To automatically download and restructure both datasets, please execute: ``` bash restructure_data.sh faceforensics_download.py ``` Note: You need to have received the download script from FaceForensics++ people before executing the restructure script. Note2: We created the `restructure_data.sh` to do a split that replicates our exact experiments avaiable in the UI above, please feel free to change the splits as you wish. ## Walkthrough Before starting to train/evaluate models, we should first create the docker image that we will be running our experiments with. To do so, we already prepared a dockerfile to do that inside `custom_docker_image`. To create the docker image, execute the following commands in terminal: ``` cd custom_docker_image nvidia-docker build . -t atlas_ff ``` Note: if you change the image name, please make sure you also modify line 16 of `job.config.yaml` to match the docker image name. Inside `job.config.yaml`, please modify the data path on host from `/media/biggie2/FaceForensics/datasets/` to the absolute path of your `datasets` folder. The folder containing your datasets should have the following structure: ``` datasets ├── augment_deepfake (2) │ ├── fake │ │ └── frames │ ├── real │ │ └── frames │ └── val │ ├── fake │ └── real ├── base_deepfake (1) │ ├── fake │ │ └── frames │ ├── real │ │ └── frames │ └── val │ ├── fake │ └── real ├── both_deepfake (3) │ ├── fake │ │ └── frames │ ├── real │ │ └── frames │ └── val │ ├── fake │ └── real ├── precomputed (4) └── T_deepfake (0) ├── manipulated_sequences │ ├── DeepFakeDetection │ ├── Deepfakes │ ├── Face2Face │ ├── FaceSwap │ └── NeuralTextures └── original_sequences ├── actors └── youtube ``` Notes: * (0) is the dataset downloaded using the FaceForensics repo scripts * (1) is a reshaped version of FaceForensics data to match the expected structure by the codebase. subfolders called `frames` contain frames collected using `ffmpeg` * (2) is the augmented dataset, collected from youtube, available on s3. * (3) is the combination of both base and augmented datasets. * (4) precomputed will be automatically created during training. It holds cashed cropped frames. Then, to run all the experiments we will show in the article to come, you can launch the script `hparams_search.py` using: ```bash python hparams_search.py ``` ## Results In the following pictures, the title for each subplot is in the form `real_prob, fake_prob | prediction | label`. #### Model trained on FaceForensics++ dataset For models trained on the paper dataset alone, we notice that the model only learns to detect the manipulation techniques mentioned in the paper and misses all the manipulations in real world data (from data)   #### Model trained on Youtube dataset Models trained on the youtube data alone learn to detect real world deepfakes, but also learn to detect easy deepfakes in the paper dataset as well. These models however fail to detect any other type of manipulation (such as NeuralTextures).   #### Model trained on Paper + Youtube dataset Finally, models trained on the combination of both datasets together, learns to detect both real world manipulation techniques as well as the other methods mentioned in FaceForensics++ paper.   for a more in depth explanation of these results, please refer to the [article](https://www.dessa.com/post/deepfake-detection-that-actually-works) we published. More results can be seen in the [interactive UI](http://deepfake-detection.dessa.com/projects) ## Help improve this technology Please feel free to fork this work and keep pushing on it. If you also want to help improving the deepfake detection datasets, please share your real/forged samples at foundations@dessa.com. ## LICENSE © 2020 Square, Inc.

NordPerfEngg / OracleDBALiteApplication: DBALite Oracle Database Performance Summary App Application Purpose: Provide Oracle host and database performance info suitable for non-dbas. Target users are Non-dba performance engineers, testers, prod support staff and application team members who want to proactively and reactively monitor their databases. Licensing: Because this App queries the dba_hist_sqlstat AWR data, a license must exist for the Oracle Diagnostic Pack. Most facilities running Oracle databases have this license. Application Basic Structure: Four stored procedures run in the Oracle database. They read performance data tables and write it out to datafiles which are consumed by Splunk. Oracle Scheduler jobs execute the stored procedures at configurable intervals. The app also uses the Splunk Add-on for Unix and Linux to get host metrics. Dependencies: Splunk Add-on for Unix and Linux (http://docs.splunk.com/Documentation/UnixAddOn/latest/User/InstalltheSplunkAdd-onforUnixandLinux) Stored procedures and scheduler jobs running in Oracle Database 11.1 or higher (procedures scripts included in the setup files.) Index creation: Splunk Add-on For Unix and Linux will create the 'unix_metrics' index. This DBALite app will create the 'database' index. Sourcetypes: om:oracle:locks -- snapshot information about blocking locks om:oracle:memory -- Oracle sga and pga memory statistics om:oracle:osstat -- Operating System stats from v$osstat table om:oracle:sql -- top resource consuming sqls from dba_hist_sqlstat om:oracle:sqltext -- sqltext for the top resource consuming sqls om:oracle:sysevent -- wait event information om:oracle:sysstat -- performance statistics from v$sysstat table Installation: Oracle Setup: Copy all the sql scripts from the Oracle_Performance_Summary_For_Splunk/bin directory to your database server or run them in SQL Developer or other tool. Connect to your database. As sysdba, create the splunk sch_spl user. (Sysdba is required for this one script in order to grant privileges on DBMS_LOCK and UTL_FILE: @cr_sch_spl.sql Create a unix directory where you want Oracle to write the output files. Splunk will pick up the data from these output files created by the stored procedures. If the owner of the directory is not the ORACLE user, then make the ORACLE user a member of the Unix group for the directory so that Oracle can write to the directory. Make the permissions on the directory 774. Note: For a RAC database, just create the directory on one node. The app is not elaborate enough to provide failover capabilities, so in case of an outage of its node, the data would just not be written until the node came back online. Create an Oracle Directory called 'DIR_SPLUNK' using the above unix directory. Example: CREATE DIRECTORY dir_splunk as '/u01/perf/dbdashboard/data'; grant read,write on directory dir_splunk to sch_spl; As the splunk user SCH_SPL, create the stored procedures and scheduler jobs that will run them: @cr_procs_and_jobs.sql After 10 minutes, check the data files to confirm there is data being written to them. These data files should exist: dbd_locks.txt dbd_memory.txt dbd_osstat.txt dbd_sysevents.txt dbd_sysstat.txt dbd_top_sql_text.txt dbd_top_sql.txt To check the scheduler jobs, as SCH_SPL user, execute: 'SELECT job_name, actual_start_date, status, additional_info from user_scheduler_job_run_details order by actual_start_date;'

pdwytr / Optimizing Windmill Layout Competition By Shell LtdShell.ai Hackathon for Sustainable and Affordable Energy The world needs to move to a cleaner energy system if it is to meet growing energy demand while tackling climate change. In April 2020, Shell shared its ambition to become a net-zero emissions energy business by 2050, or sooner. Renewable electricity is central to this ambition. Electricity is the fastest-growing part of the energy system and, when generated from renewable sources such as wind, has a big role to play in reducing greenhouse gas emissions. We see digitalisation and AI as key enablers to the energy transition. Challenge: Windfarm Layout Optimisation In this Shell.ai Hackathon for Sustainable and Affordable Energy, we invite you to optimise the placement of 50 wind turbines of 100 m height and100 m rotor diameter each on a hypothetical 2D offshore wind farm area such that the AEP (Annual Energy Production) of the farm is maximized. One of the key problems of an unoptimized layout is the combined effect wind turbines can have on the wind speed distribution in a windfarm. As a wind turbine extracts energy from incoming wind, it creates a region behind it downstream where the wind speed is decreased- this is called a wake region. Note that wind turbines automatically orient their rotors, to face incoming wind from any direction. Due to the induced speed deficit, a turbine placed inside the wake region of an upstream turbine will naturally generate reduced electrical power. This inter-turbine interference is known as a wake effect. An optimal windfarm layout is important to ensure a minimum loss of power during this combined wake effect. This Shell.ai Hackathon for Sustainable and Affordable Energy edition, focuses on an interesting and complex coding problem. When competing, you will face challenges such as a high dimensionality, complex multimodality and the discontinuous nature of the search space. This makes optimizing the layout analytics difficult. But, armed with optimization strategies and computer algorithms, you can solve this problem.
Aryia-Behroziuan / NumpyQuickstart tutorial Prerequisites Before reading this tutorial you should know a bit of Python. If you would like to refresh your memory, take a look at the Python tutorial. If you wish to work the examples in this tutorial, you must also have some software installed on your computer. Please see https://scipy.org/install.html for instructions. Learner profile This tutorial is intended as a quick overview of algebra and arrays in NumPy and want to understand how n-dimensional (n>=2) arrays are represented and can be manipulated. In particular, if you don’t know how to apply common functions to n-dimensional arrays (without using for-loops), or if you want to understand axis and shape properties for n-dimensional arrays, this tutorial might be of help. Learning Objectives After this tutorial, you should be able to: Understand the difference between one-, two- and n-dimensional arrays in NumPy; Understand how to apply some linear algebra operations to n-dimensional arrays without using for-loops; Understand axis and shape properties for n-dimensional arrays. The Basics NumPy’s main object is the homogeneous multidimensional array. It is a table of elements (usually numbers), all of the same type, indexed by a tuple of non-negative integers. In NumPy dimensions are called axes. For example, the coordinates of a point in 3D space [1, 2, 1] has one axis. That axis has 3 elements in it, so we say it has a length of 3. In the example pictured below, the array has 2 axes. The first axis has a length of 2, the second axis has a length of 3. [[ 1., 0., 0.], [ 0., 1., 2.]] NumPy’s array class is called ndarray. It is also known by the alias array. Note that numpy.array is not the same as the Standard Python Library class array.array, which only handles one-dimensional arrays and offers less functionality. The more important attributes of an ndarray object are: ndarray.ndim the number of axes (dimensions) of the array. ndarray.shape the dimensions of the array. This is a tuple of integers indicating the size of the array in each dimension. For a matrix with n rows and m columns, shape will be (n,m). The length of the shape tuple is therefore the number of axes, ndim. ndarray.size the total number of elements of the array. This is equal to the product of the elements of shape. ndarray.dtype an object describing the type of the elements in the array. One can create or specify dtype’s using standard Python types. Additionally NumPy provides types of its own. numpy.int32, numpy.int16, and numpy.float64 are some examples. ndarray.itemsize the size in bytes of each element of the array. For example, an array of elements of type float64 has itemsize 8 (=64/8), while one of type complex32 has itemsize 4 (=32/8). It is equivalent to ndarray.dtype.itemsize. ndarray.data the buffer containing the actual elements of the array. Normally, we won’t need to use this attribute because we will access the elements in an array using indexing facilities. An example >>> import numpy as np a = np.arange(15).reshape(3, 5) a array([[ 0, 1, 2, 3, 4], [ 5, 6, 7, 8, 9], [10, 11, 12, 13, 14]]) a.shape (3, 5) a.ndim 2 a.dtype.name 'int64' a.itemsize 8 a.size 15 type(a) <class 'numpy.ndarray'> b = np.array([6, 7, 8]) b array([6, 7, 8]) type(b) <class 'numpy.ndarray'> Array Creation There are several ways to create arrays. For example, you can create an array from a regular Python list or tuple using the array function. The type of the resulting array is deduced from the type of the elements in the sequences. >>> >>> import numpy as np >>> a = np.array([2,3,4]) >>> a array([2, 3, 4]) >>> a.dtype dtype('int64') >>> b = np.array([1.2, 3.5, 5.1]) >>> b.dtype dtype('float64') A frequent error consists in calling array with multiple arguments, rather than providing a single sequence as an argument. >>> >>> a = np.array(1,2,3,4) # WRONG Traceback (most recent call last): ... TypeError: array() takes from 1 to 2 positional arguments but 4 were given >>> a = np.array([1,2,3,4]) # RIGHT array transforms sequences of sequences into two-dimensional arrays, sequences of sequences of sequences into three-dimensional arrays, and so on. >>> >>> b = np.array([(1.5,2,3), (4,5,6)]) >>> b array([[1.5, 2. , 3. ], [4. , 5. , 6. ]]) The type of the array can also be explicitly specified at creation time: >>> >>> c = np.array( [ [1,2], [3,4] ], dtype=complex ) >>> c array([[1.+0.j, 2.+0.j], [3.+0.j, 4.+0.j]]) Often, the elements of an array are originally unknown, but its size is known. Hence, NumPy offers several functions to create arrays with initial placeholder content. These minimize the necessity of growing arrays, an expensive operation. The function zeros creates an array full of zeros, the function ones creates an array full of ones, and the function empty creates an array whose initial content is random and depends on the state of the memory. By default, the dtype of the created array is float64. >>> >>> np.zeros((3, 4)) array([[0., 0., 0., 0.], [0., 0., 0., 0.], [0., 0., 0., 0.]]) >>> np.ones( (2,3,4), dtype=np.int16 ) # dtype can also be specified array([[[1, 1, 1, 1], [1, 1, 1, 1], [1, 1, 1, 1]], [[1, 1, 1, 1], [1, 1, 1, 1], [1, 1, 1, 1]]], dtype=int16) >>> np.empty( (2,3) ) # uninitialized array([[ 3.73603959e-262, 6.02658058e-154, 6.55490914e-260], # may vary [ 5.30498948e-313, 3.14673309e-307, 1.00000000e+000]]) To create sequences of numbers, NumPy provides the arange function which is analogous to the Python built-in range, but returns an array. >>> >>> np.arange( 10, 30, 5 ) array([10, 15, 20, 25]) >>> np.arange( 0, 2, 0.3 ) # it accepts float arguments array([0. , 0.3, 0.6, 0.9, 1.2, 1.5, 1.8]) When arange is used with floating point arguments, it is generally not possible to predict the number of elements obtained, due to the finite floating point precision. For this reason, it is usually better to use the function linspace that receives as an argument the number of elements that we want, instead of the step: >>> >>> from numpy import pi >>> np.linspace( 0, 2, 9 ) # 9 numbers from 0 to 2 array([0. , 0.25, 0.5 , 0.75, 1. , 1.25, 1.5 , 1.75, 2. ]) >>> x = np.linspace( 0, 2*pi, 100 ) # useful to evaluate function at lots of points >>> f = np.sin(x) See also array, zeros, zeros_like, ones, ones_like, empty, empty_like, arange, linspace, numpy.random.Generator.rand, numpy.random.Generator.randn, fromfunction, fromfile Printing Arrays When you print an array, NumPy displays it in a similar way to nested lists, but with the following layout: the last axis is printed from left to right, the second-to-last is printed from top to bottom, the rest are also printed from top to bottom, with each slice separated from the next by an empty line. One-dimensional arrays are then printed as rows, bidimensionals as matrices and tridimensionals as lists of matrices. >>> >>> a = np.arange(6) # 1d array >>> print(a) [0 1 2 3 4 5] >>> >>> b = np.arange(12).reshape(4,3) # 2d array >>> print(b) [[ 0 1 2] [ 3 4 5] [ 6 7 8] [ 9 10 11]] >>> >>> c = np.arange(24).reshape(2,3,4) # 3d array >>> print(c) [[[ 0 1 2 3] [ 4 5 6 7] [ 8 9 10 11]] [[12 13 14 15] [16 17 18 19] [20 21 22 23]]] See below to get more details on reshape. If an array is too large to be printed, NumPy automatically skips the central part of the array and only prints the corners: >>> >>> print(np.arange(10000)) [ 0 1 2 ... 9997 9998 9999] >>> >>> print(np.arange(10000).reshape(100,100)) [[ 0 1 2 ... 97 98 99] [ 100 101 102 ... 197 198 199] [ 200 201 202 ... 297 298 299] ... [9700 9701 9702 ... 9797 9798 9799] [9800 9801 9802 ... 9897 9898 9899] [9900 9901 9902 ... 9997 9998 9999]] To disable this behaviour and force NumPy to print the entire array, you can change the printing options using set_printoptions. >>> >>> np.set_printoptions(threshold=sys.maxsize) # sys module should be imported Basic Operations Arithmetic operators on arrays apply elementwise. A new array is created and filled with the result. >>> >>> a = np.array( [20,30,40,50] ) >>> b = np.arange( 4 ) >>> b array([0, 1, 2, 3]) >>> c = a-b >>> c array([20, 29, 38, 47]) >>> b**2 array([0, 1, 4, 9]) >>> 10*np.sin(a) array([ 9.12945251, -9.88031624, 7.4511316 , -2.62374854]) >>> a<35 array([ True, True, False, False]) Unlike in many matrix languages, the product operator * operates elementwise in NumPy arrays. The matrix product can be performed using the @ operator (in python >=3.5) or the dot function or method: >>> >>> A = np.array( [[1,1], ... [0,1]] ) >>> B = np.array( [[2,0], ... [3,4]] ) >>> A * B # elementwise product array([[2, 0], [0, 4]]) >>> A @ B # matrix product array([[5, 4], [3, 4]]) >>> A.dot(B) # another matrix product array([[5, 4], [3, 4]]) Some operations, such as += and *=, act in place to modify an existing array rather than create a new one. >>> >>> rg = np.random.default_rng(1) # create instance of default random number generator >>> a = np.ones((2,3), dtype=int) >>> b = rg.random((2,3)) >>> a *= 3 >>> a array([[3, 3, 3], [3, 3, 3]]) >>> b += a >>> b array([[3.51182162, 3.9504637 , 3.14415961], [3.94864945, 3.31183145, 3.42332645]]) >>> a += b # b is not automatically converted to integer type Traceback (most recent call last): ... numpy.core._exceptions.UFuncTypeError: Cannot cast ufunc 'add' output from dtype('float64') to dtype('int64') with casting rule 'same_kind' When operating with arrays of different types, the type of the resulting array corresponds to the more general or precise one (a behavior known as upcasting). >>> >>> a = np.ones(3, dtype=np.int32) >>> b = np.linspace(0,pi,3) >>> b.dtype.name 'float64' >>> c = a+b >>> c array([1. , 2.57079633, 4.14159265]) >>> c.dtype.name 'float64' >>> d = np.exp(c*1j) >>> d array([ 0.54030231+0.84147098j, -0.84147098+0.54030231j, -0.54030231-0.84147098j]) >>> d.dtype.name 'complex128' Many unary operations, such as computing the sum of all the elements in the array, are implemented as methods of the ndarray class. >>> >>> a = rg.random((2,3)) >>> a array([[0.82770259, 0.40919914, 0.54959369], [0.02755911, 0.75351311, 0.53814331]]) >>> a.sum() 3.1057109529998157 >>> a.min() 0.027559113243068367 >>> a.max() 0.8277025938204418 By default, these operations apply to the array as though it were a list of numbers, regardless of its shape. However, by specifying the axis parameter you can apply an operation along the specified axis of an array: >>> >>> b = np.arange(12).reshape(3,4) >>> b array([[ 0, 1, 2, 3], [ 4, 5, 6, 7], [ 8, 9, 10, 11]]) >>> >>> b.sum(axis=0) # sum of each column array([12, 15, 18, 21]) >>> >>> b.min(axis=1) # min of each row array([0, 4, 8]) >>> >>> b.cumsum(axis=1) # cumulative sum along each row array([[ 0, 1, 3, 6], [ 4, 9, 15, 22], [ 8, 17, 27, 38]]) Universal Functions NumPy provides familiar mathematical functions such as sin, cos, and exp. In NumPy, these are called “universal functions”(ufunc). Within NumPy, these functions operate elementwise on an array, producing an array as output. >>> >>> B = np.arange(3) >>> B array([0, 1, 2]) >>> np.exp(B) array([1. , 2.71828183, 7.3890561 ]) >>> np.sqrt(B) array([0. , 1. , 1.41421356]) >>> C = np.array([2., -1., 4.]) >>> np.add(B, C) array([2., 0., 6.]) See also all, any, apply_along_axis, argmax, argmin, argsort, average, bincount, ceil, clip, conj, corrcoef, cov, cross, cumprod, cumsum, diff, dot, floor, inner, invert, lexsort, max, maximum, mean, median, min, minimum, nonzero, outer, prod, re, round, sort, std, sum, trace, transpose, var, vdot, vectorize, where Indexing, Slicing and Iterating One-dimensional arrays can be indexed, sliced and iterated over, much like lists and other Python sequences. >>> >>> a = np.arange(10)**3 >>> a array([ 0, 1, 8, 27, 64, 125, 216, 343, 512, 729]) >>> a[2] 8 >>> a[2:5] array([ 8, 27, 64]) # equivalent to a[0:6:2] = 1000; # from start to position 6, exclusive, set every 2nd element to 1000 >>> a[:6:2] = 1000 >>> a array([1000, 1, 1000, 27, 1000, 125, 216, 343, 512, 729]) >>> a[ : :-1] # reversed a array([ 729, 512, 343, 216, 125, 1000, 27, 1000, 1, 1000]) >>> for i in a: ... print(i**(1/3.)) ... 9.999999999999998 1.0 9.999999999999998 3.0 9.999999999999998 4.999999999999999 5.999999999999999 6.999999999999999 7.999999999999999 8.999999999999998 Multidimensional arrays can have one index per axis. These indices are given in a tuple separated by commas: >>> >>> def f(x,y): ... return 10*x+y ... >>> b = np.fromfunction(f,(5,4),dtype=int) >>> b array([[ 0, 1, 2, 3], [10, 11, 12, 13], [20, 21, 22, 23], [30, 31, 32, 33], [40, 41, 42, 43]]) >>> b[2,3] 23 >>> b[0:5, 1] # each row in the second column of b array([ 1, 11, 21, 31, 41]) >>> b[ : ,1] # equivalent to the previous example array([ 1, 11, 21, 31, 41]) >>> b[1:3, : ] # each column in the second and third row of b array([[10, 11, 12, 13], [20, 21, 22, 23]]) When fewer indices are provided than the number of axes, the missing indices are considered complete slices: >>> >>> b[-1] # the last row. Equivalent to b[-1,:] array([40, 41, 42, 43]) The expression within brackets in b[i] is treated as an i followed by as many instances of : as needed to represent the remaining axes. NumPy also allows you to write this using dots as b[i,...]. The dots (...) represent as many colons as needed to produce a complete indexing tuple. For example, if x is an array with 5 axes, then x[1,2,...] is equivalent to x[1,2,:,:,:], x[...,3] to x[:,:,:,:,3] and x[4,...,5,:] to x[4,:,:,5,:]. >>> >>> c = np.array( [[[ 0, 1, 2], # a 3D array (two stacked 2D arrays) ... [ 10, 12, 13]], ... [[100,101,102], ... [110,112,113]]]) >>> c.shape (2, 2, 3) >>> c[1,...] # same as c[1,:,:] or c[1] array([[100, 101, 102], [110, 112, 113]]) >>> c[...,2] # same as c[:,:,2] array([[ 2, 13], [102, 113]]) Iterating over multidimensional arrays is done with respect to the first axis: >>> >>> for row in b: ... print(row) ... [0 1 2 3] [10 11 12 13] [20 21 22 23] [30 31 32 33] [40 41 42 43] However, if one wants to perform an operation on each element in the array, one can use the flat attribute which is an iterator over all the elements of the array: >>> >>> for element in b.flat: ... print(element) ... 0 1 2 3 10 11 12 13 20 21 22 23 30 31 32 33 40 41 42 43 See also Indexing, Indexing (reference), newaxis, ndenumerate, indices Shape Manipulation Changing the shape of an array An array has a shape given by the number of elements along each axis: >>> >>> a = np.floor(10*rg.random((3,4))) >>> a array([[3., 7., 3., 4.], [1., 4., 2., 2.], [7., 2., 4., 9.]]) >>> a.shape (3, 4) The shape of an array can be changed with various commands. Note that the following three commands all return a modified array, but do not change the original array: >>> >>> a.ravel() # returns the array, flattened array([3., 7., 3., 4., 1., 4., 2., 2., 7., 2., 4., 9.]) >>> a.reshape(6,2) # returns the array with a modified shape array([[3., 7.], [3., 4.], [1., 4.], [2., 2.], [7., 2.], [4., 9.]]) >>> a.T # returns the array, transposed array([[3., 1., 7.], [7., 4., 2.], [3., 2., 4.], [4., 2., 9.]]) >>> a.T.shape (4, 3) >>> a.shape (3, 4) The order of the elements in the array resulting from ravel() is normally “C-style”, that is, the rightmost index “changes the fastest”, so the element after a[0,0] is a[0,1]. If the array is reshaped to some other shape, again the array is treated as “C-style”. NumPy normally creates arrays stored in this order, so ravel() will usually not need to copy its argument, but if the array was made by taking slices of another array or created with unusual options, it may need to be copied. The functions ravel() and reshape() can also be instructed, using an optional argument, to use FORTRAN-style arrays, in which the leftmost index changes the fastest. The reshape function returns its argument with a modified shape, whereas the ndarray.resize method modifies the array itself: >>> >>> a array([[3., 7., 3., 4.], [1., 4., 2., 2.], [7., 2., 4., 9.]]) >>> a.resize((2,6)) >>> a array([[3., 7., 3., 4., 1., 4.], [2., 2., 7., 2., 4., 9.]]) If a dimension is given as -1 in a reshaping operation, the other dimensions are automatically calculated: >>> >>> a.reshape(3,-1) array([[3., 7., 3., 4.], [1., 4., 2., 2.], [7., 2., 4., 9.]]) See also ndarray.shape, reshape, resize, ravel Stacking together different arrays Several arrays can be stacked together along different axes: >>> >>> a = np.floor(10*rg.random((2,2))) >>> a array([[9., 7.], [5., 2.]]) >>> b = np.floor(10*rg.random((2,2))) >>> b array([[1., 9.], [5., 1.]]) >>> np.vstack((a,b)) array([[9., 7.], [5., 2.], [1., 9.], [5., 1.]]) >>> np.hstack((a,b)) array([[9., 7., 1., 9.], [5., 2., 5., 1.]]) The function column_stack stacks 1D arrays as columns into a 2D array. It is equivalent to hstack only for 2D arrays: >>> >>> from numpy import newaxis >>> np.column_stack((a,b)) # with 2D arrays array([[9., 7., 1., 9.], [5., 2., 5., 1.]]) >>> a = np.array([4.,2.]) >>> b = np.array([3.,8.]) >>> np.column_stack((a,b)) # returns a 2D array array([[4., 3.], [2., 8.]]) >>> np.hstack((a,b)) # the result is different array([4., 2., 3., 8.]) >>> a[:,newaxis] # view `a` as a 2D column vector array([[4.], [2.]]) >>> np.column_stack((a[:,newaxis],b[:,newaxis])) array([[4., 3.], [2., 8.]]) >>> np.hstack((a[:,newaxis],b[:,newaxis])) # the result is the same array([[4., 3.], [2., 8.]]) On the other hand, the function row_stack is equivalent to vstack for any input arrays. In fact, row_stack is an alias for vstack: >>> >>> np.column_stack is np.hstack False >>> np.row_stack is np.vstack True In general, for arrays with more than two dimensions, hstack stacks along their second axes, vstack stacks along their first axes, and concatenate allows for an optional arguments giving the number of the axis along which the concatenation should happen. Note In complex cases, r_ and c_ are useful for creating arrays by stacking numbers along one axis. They allow the use of range literals (“:”) >>> >>> np.r_[1:4,0,4] array([1, 2, 3, 0, 4]) When used with arrays as arguments, r_ and c_ are similar to vstack and hstack in their default behavior, but allow for an optional argument giving the number of the axis along which to concatenate. See also hstack, vstack, column_stack, concatenate, c_, r_ Splitting one array into several smaller ones Using hsplit, you can split an array along its horizontal axis, either by specifying the number of equally shaped arrays to return, or by specifying the columns after which the division should occur: >>> >>> a = np.floor(10*rg.random((2,12))) >>> a array([[6., 7., 6., 9., 0., 5., 4., 0., 6., 8., 5., 2.], [8., 5., 5., 7., 1., 8., 6., 7., 1., 8., 1., 0.]]) # Split a into 3 >>> np.hsplit(a,3) [array([[6., 7., 6., 9.], [8., 5., 5., 7.]]), array([[0., 5., 4., 0.], [1., 8., 6., 7.]]), array([[6., 8., 5., 2.], [1., 8., 1., 0.]])] # Split a after the third and the fourth column >>> np.hsplit(a,(3,4)) [array([[6., 7., 6.], [8., 5., 5.]]), array([[9.], [7.]]), array([[0., 5., 4., 0., 6., 8., 5., 2.], [1., 8., 6., 7., 1., 8., 1., 0.]])] vsplit splits along the vertical axis, and array_split allows one to specify along which axis to split. Copies and Views When operating and manipulating arrays, their data is sometimes copied into a new array and sometimes not. This is often a source of confusion for beginners. There are three cases: No Copy at All Simple assignments make no copy of objects or their data. >>> >>> a = np.array([[ 0, 1, 2, 3], ... [ 4, 5, 6, 7], ... [ 8, 9, 10, 11]]) >>> b = a # no new object is created >>> b is a # a and b are two names for the same ndarray object True Python passes mutable objects as references, so function calls make no copy. >>> >>> def f(x): ... print(id(x)) ... >>> id(a) # id is a unique identifier of an object 148293216 # may vary >>> f(a) 148293216 # may vary View or Shallow Copy Different array objects can share the same data. The view method creates a new array object that looks at the same data. >>> >>> c = a.view() >>> c is a False >>> c.base is a # c is a view of the data owned by a True >>> c.flags.owndata False >>> >>> c = c.reshape((2, 6)) # a's shape doesn't change >>> a.shape (3, 4) >>> c[0, 4] = 1234 # a's data changes >>> a array([[ 0, 1, 2, 3], [1234, 5, 6, 7], [ 8, 9, 10, 11]]) Slicing an array returns a view of it: >>> >>> s = a[ : , 1:3] # spaces added for clarity; could also be written "s = a[:, 1:3]" >>> s[:] = 10 # s[:] is a view of s. Note the difference between s = 10 and s[:] = 10 >>> a array([[ 0, 10, 10, 3], [1234, 10, 10, 7], [ 8, 10, 10, 11]]) Deep Copy The copy method makes a complete copy of the array and its data. >>> >>> d = a.copy() # a new array object with new data is created >>> d is a False >>> d.base is a # d doesn't share anything with a False >>> d[0,0] = 9999 >>> a array([[ 0, 10, 10, 3], [1234, 10, 10, 7], [ 8, 10, 10, 11]]) Sometimes copy should be called after slicing if the original array is not required anymore. For example, suppose a is a huge intermediate result and the final result b only contains a small fraction of a, a deep copy should be made when constructing b with slicing: >>> >>> a = np.arange(int(1e8)) >>> b = a[:100].copy() >>> del a # the memory of ``a`` can be released. If b = a[:100] is used instead, a is referenced by b and will persist in memory even if del a is executed. Functions and Methods Overview Here is a list of some useful NumPy functions and methods names ordered in categories. See Routines for the full list.

The first rule of broadcasting is that if all input arrays do not have the same number of dimensions, a “1” will be repeatedly prepended to the shapes of the smaller arrays until all the arrays have the same number of dimensions. The second rule of broadcasting ensures that arrays with a size of 1 along a particular dimension act as if they had the size of the array with the largest shape along that dimension. The value of the array element is assumed to be the same along that dimension for the “broadcast” array. After application of the broadcasting rules, the sizes of all arrays must match. More details can be found in Broadcasting. Advanced indexing and index tricks NumPy offers more indexing facilities than regular Python sequences. In addition to indexing by integers and slices, as we saw before, arrays can be indexed by arrays of integers and arrays of booleans. Indexing with Arrays of Indices >>> >>> a = np.arange(12)**2 # the first 12 square numbers >>> i = np.array([1, 1, 3, 8, 5]) # an array of indices >>> a[i] # the elements of a at the positions i array([ 1, 1, 9, 64, 25]) >>> >>> j = np.array([[3, 4], [9, 7]]) # a bidimensional array of indices >>> a[j] # the same shape as j array([[ 9, 16], [81, 49]]) When the indexed array a is multidimensional, a single array of indices refers to the first dimension of a. The following example shows this behavior by converting an image of labels into a color image using a palette. >>> >>> palette = np.array([[0, 0, 0], # black ... [255, 0, 0], # red ... [0, 255, 0], # green ... [0, 0, 255], # blue ... [255, 255, 255]]) # white >>> image = np.array([[0, 1, 2, 0], # each value corresponds to a color in the palette ... [0, 3, 4, 0]]) >>> palette[image] # the (2, 4, 3) color image array([[[ 0, 0, 0], [255, 0, 0], [ 0, 255, 0], [ 0, 0, 0]], [[ 0, 0, 0], [ 0, 0, 255], [255, 255, 255], [ 0, 0, 0]]]) We can also give indexes for more than one dimension. The arrays of indices for each dimension must have the same shape. >>> >>> a = np.arange(12).reshape(3,4) >>> a array([[ 0, 1, 2, 3], [ 4, 5, 6, 7], [ 8, 9, 10, 11]]) >>> i = np.array([[0, 1], # indices for the first dim of a ... [1, 2]]) >>> j = np.array([[2, 1], # indices for the second dim ... [3, 3]]) >>> >>> a[i, j] # i and j must have equal shape array([[ 2, 5], [ 7, 11]]) >>> >>> a[i, 2] array([[ 2, 6], [ 6, 10]]) >>> >>> a[:, j] # i.e., a[ : , j] array([[[ 2, 1], [ 3, 3]], [[ 6, 5], [ 7, 7]], [[10, 9], [11, 11]]]) In Python, arr[i, j] is exactly the same as arr[(i, j)]—so we can put i and j in a tuple and then do the indexing with that. >>> >>> l = (i, j) # equivalent to a[i, j] >>> a[l] array([[ 2, 5], [ 7, 11]]) However, we can not do this by putting i and j into an array, because this array will be interpreted as indexing the first dimension of a. >>> >>> s = np.array([i, j]) # not what we want >>> a[s] Traceback (most recent call last): File "<stdin>", line 1, in <module> IndexError: index 3 is out of bounds for axis 0 with size 3 # same as a[i, j] >>> a[tuple(s)] array([[ 2, 5], [ 7, 11]]) Another common use of indexing with arrays is the search of the maximum value of time-dependent series: >>> >>> time = np.linspace(20, 145, 5) # time scale >>> data = np.sin(np.arange(20)).reshape(5,4) # 4 time-dependent series >>> time array([ 20. , 51.25, 82.5 , 113.75, 145. ]) >>> data array([[ 0. , 0.84147098, 0.90929743, 0.14112001], [-0.7568025 , -0.95892427, -0.2794155 , 0.6569866 ], [ 0.98935825, 0.41211849, -0.54402111, -0.99999021], [-0.53657292, 0.42016704, 0.99060736, 0.65028784], [-0.28790332, -0.96139749, -0.75098725, 0.14987721]]) # index of the maxima for each series >>> ind = data.argmax(axis=0) >>> ind array([2, 0, 3, 1]) # times corresponding to the maxima >>> time_max = time[ind] >>> >>> data_max = data[ind, range(data.shape[1])] # => data[ind[0],0], data[ind[1],1]... >>> time_max array([ 82.5 , 20. , 113.75, 51.25]) >>> data_max array([0.98935825, 0.84147098, 0.99060736, 0.6569866 ]) >>> np.all(data_max == data.max(axis=0)) True You can also use indexing with arrays as a target to assign to: >>> >>> a = np.arange(5) >>> a array([0, 1, 2, 3, 4]) >>> a[[1,3,4]] = 0 >>> a array([0, 0, 2, 0, 0]) However, when the list of indices contains repetitions, the assignment is done several times, leaving behind the last value: >>> >>> a = np.arange(5) >>> a[[0,0,2]]=[1,2,3] >>> a array([2, 1, 3, 3, 4]) This is reasonable enough, but watch out if you want to use Python’s += construct, as it may not do what you expect: >>> >>> a = np.arange(5) >>> a[[0,0,2]]+=1 >>> a array([1, 1, 3, 3, 4]) Even though 0 occurs twice in the list of indices, the 0th element is only incremented once. This is because Python requires “a+=1” to be equivalent to “a = a + 1”. Indexing with Boolean Arrays When we index arrays with arrays of (integer) indices we are providing the list of indices to pick. With boolean indices the approach is different; we explicitly choose which items in the array we want and which ones we don’t. The most natural way one can think of for boolean indexing is to use boolean arrays that have the same shape as the original array: >>> >>> a = np.arange(12).reshape(3,4) >>> b = a > 4 >>> b # b is a boolean with a's shape array([[False, False, False, False], [False, True, True, True], [ True, True, True, True]]) >>> a[b] # 1d array with the selected elements array([ 5, 6, 7, 8, 9, 10, 11]) This property can be very useful in assignments: >>> >>> a[b] = 0 # All elements of 'a' higher than 4 become 0 >>> a array([[0, 1, 2, 3], [4, 0, 0, 0], [0, 0, 0, 0]]) You can look at the following example to see how to use boolean indexing to generate an image of the Mandelbrot set: >>> import numpy as np import matplotlib.pyplot as plt def mandelbrot( h,w, maxit=20 ): """Returns an image of the Mandelbrot fractal of size (h,w).""" y,x = np.ogrid[ -1.4:1.4:h*1j, -2:0.8:w*1j ] c = x+y*1j z = c divtime = maxit + np.zeros(z.shape, dtype=int) for i in range(maxit): z = z**2 + c diverge = z*np.conj(z) > 2**2 # who is diverging div_now = diverge & (divtime==maxit) # who is diverging now divtime[div_now] = i # note when z[diverge] = 2 # avoid diverging too much return divtime plt.imshow(mandelbrot(400,400)) ../_images/quickstart-1.png The second way of indexing with booleans is more similar to integer indexing; for each dimension of the array we give a 1D boolean array selecting the slices we want: >>> >>> a = np.arange(12).reshape(3,4) >>> b1 = np.array([False,True,True]) # first dim selection >>> b2 = np.array([True,False,True,False]) # second dim selection >>> >>> a[b1,:] # selecting rows array([[ 4, 5, 6, 7], [ 8, 9, 10, 11]]) >>> >>> a[b1] # same thing array([[ 4, 5, 6, 7], [ 8, 9, 10, 11]]) >>> >>> a[:,b2] # selecting columns array([[ 0, 2], [ 4, 6], [ 8, 10]]) >>> >>> a[b1,b2] # a weird thing to do array([ 4, 10]) Note that the length of the 1D boolean array must coincide with the length of the dimension (or axis) you want to slice. In the previous example, b1 has length 3 (the number of rows in a), and b2 (of length 4) is suitable to index the 2nd axis (columns) of a. The ix_() function The ix_ function can be used to combine different vectors so as to obtain the result for each n-uplet. For example, if you want to compute all the a+b*c for all the triplets taken from each of the vectors a, b and c: >>> >>> a = np.array([2,3,4,5]) >>> b = np.array([8,5,4]) >>> c = np.array([5,4,6,8,3]) >>> ax,bx,cx = np.ix_(a,b,c) >>> ax array([[[2]], [[3]], [[4]], [[5]]]) >>> bx array([[[8], [5], [4]]]) >>> cx array([[[5, 4, 6, 8, 3]]]) >>> ax.shape, bx.shape, cx.shape ((4, 1, 1), (1, 3, 1), (1, 1, 5)) >>> result = ax+bx*cx >>> result array([[[42, 34, 50, 66, 26], [27, 22, 32, 42, 17], [22, 18, 26, 34, 14]], [[43, 35, 51, 67, 27], [28, 23, 33, 43, 18], [23, 19, 27, 35, 15]], [[44, 36, 52, 68, 28], [29, 24, 34, 44, 19], [24, 20, 28, 36, 16]], [[45, 37, 53, 69, 29], [30, 25, 35, 45, 20], [25, 21, 29, 37, 17]]]) >>> result[3,2,4] 17 >>> a[3]+b[2]*c[4] 17 You could also implement the reduce as follows: >>> >>> def ufunc_reduce(ufct, *vectors): ... vs = np.ix_(*vectors) ... r = ufct.identity ... for v in vs: ... r = ufct(r,v) ... return r and then use it as: >>> >>> ufunc_reduce(np.add,a,b,c) array([[[15, 14, 16, 18, 13], [12, 11, 13, 15, 10], [11, 10, 12, 14, 9]], [[16, 15, 17, 19, 14], [13, 12, 14, 16, 11], [12, 11, 13, 15, 10]], [[17, 16, 18, 20, 15], [14, 13, 15, 17, 12], [13, 12, 14, 16, 11]], [[18, 17, 19, 21, 16], [15, 14, 16, 18, 13], [14, 13, 15, 17, 12]]]) The advantage of this version of reduce compared to the normal ufunc.reduce is that it makes use of the Broadcasting Rules in order to avoid creating an argument array the size of the output times the number of vectors. Indexing with strings See Structured arrays. Linear Algebra Work in progress. Basic linear algebra to be included here. Simple Array Operations See linalg.py in numpy folder for more. >>> >>> import numpy as np >>> a = np.array([[1.0, 2.0], [3.0, 4.0]]) >>> print(a) [[1. 2.] [3. 4.]] >>> a.transpose() array([[1., 3.], [2., 4.]]) >>> np.linalg.inv(a) array([[-2. , 1. ], [ 1.5, -0.5]]) >>> u = np.eye(2) # unit 2x2 matrix; "eye" represents "I" >>> u array([[1., 0.], [0., 1.]]) >>> j = np.array([[0.0, -1.0], [1.0, 0.0]]) >>> j @ j # matrix product array([[-1., 0.], [ 0., -1.]]) >>> np.trace(u) # trace 2.0 >>> y = np.array([[5.], [7.]]) >>> np.linalg.solve(a, y) array([[-3.], [ 4.]]) >>> np.linalg.eig(j) (array([0.+1.j, 0.-1.j]), array([[0.70710678+0.j , 0.70710678-0.j ], [0. -0.70710678j, 0. +0.70710678j]])) Parameters: square matrix Returns The eigenvalues, each repeated according to its multiplicity. The normalized (unit "length") eigenvectors, such that the column ``v[:,i]`` is the eigenvector corresponding to the eigenvalue ``w[i]`` . Tricks and Tips Here we give a list of short and useful tips. “Automatic” Reshaping To change the dimensions of an array, you can omit one of the sizes which will then be deduced automatically: >>> >>> a = np.arange(30) >>> b = a.reshape((2, -1, 3)) # -1 means "whatever is needed" >>> b.shape (2, 5, 3) >>> b array([[[ 0, 1, 2], [ 3, 4, 5], [ 6, 7, 8], [ 9, 10, 11], [12, 13, 14]], [[15, 16, 17], [18, 19, 20], [21, 22, 23], [24, 25, 26], [27, 28, 29]]]) Vector Stacking How do we construct a 2D array from a list of equally-sized row vectors? In MATLAB this is quite easy: if x and y are two vectors of the same length you only need do m=[x;y]. In NumPy this works via the functions column_stack, dstack, hstack and vstack, depending on the dimension in which the stacking is to be done. For example: >>> >>> x = np.arange(0,10,2) >>> y = np.arange(5) >>> m = np.vstack([x,y]) >>> m array([[0, 2, 4, 6, 8], [0, 1, 2, 3, 4]]) >>> xy = np.hstack([x,y]) >>> xy array([0, 2, 4, 6, 8, 0, 1, 2, 3, 4]) The logic behind those functions in more than two dimensions can be strange. See also NumPy for Matlab users Histograms The NumPy histogram function applied to an array returns a pair of vectors: the histogram of the array and a vector of the bin edges. Beware: matplotlib also has a function to build histograms (called hist, as in Matlab) that differs from the one in NumPy. The main difference is that pylab.hist plots the histogram automatically, while numpy.histogram only generates the data. >>> import numpy as np rg = np.random.default_rng(1) import matplotlib.pyplot as plt # Build a vector of 10000 normal deviates with variance 0.5^2 and mean 2 mu, sigma = 2, 0.5 v = rg.normal(mu,sigma,10000) # Plot a normalized histogram with 50 bins plt.hist(v, bins=50, density=1) # matplotlib version (plot) # Compute the histogram with numpy and then plot it (n, bins) = np.histogram(v, bins=50, density=True) # NumPy version (no plot) plt.plot(.5*(bins[1:]+bins[:-1]), n) ../_images/quickstart-2.png Further reading The Python tutorial NumPy Reference SciPy Tutorial SciPy Lecture Notes A matlab, R, IDL, NumPy/SciPy dictionary © Copyright 2008-2020, The SciPy community.
