Overview

• NixOS configurations for my laptop, and old desktop server
• Determinate Nix-powered
• reproducible, and immutable full system configuration (think dotfiles, but better)

Components Used

• home-manager for user-based app/desktop configuration
• sops-nix for secrets (encrypted at rest, per-host encryption)
• lanzaboote for bootloader configuration
• determinate for getting the best version of Nix with robust defaults

What I Use

• firefox: because Google should not own the web, and Sideberry is essential for tree-style tabs

• helix: my go-to editor; TUI, Rust, modal, built-in LSP, etc

• zelij: tmux but better, with excellent UX for beginners

• openvscode-server: VSCodium-based editor; used for work and sometimes personal stuff

• COSMIC for my desktop environment:
