nixcfg

Nix rules everything around me

nixcfg

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:
