Writing
Everything I've written here.
A crew of AI agents running in my attic, each with a name, a job and a memory, plus the open-source framework that keeps them alive between sessions.
How I manage four NixOS machines (one server, three workstations) from a single flake: profiles, modular composition, sops-nix secrets, hot-reload dotfiles, and a Justfile that hides the rough edges.
Seven weeks, 62 libretro cores, a custom web dashboard streaming the screen in HW-encoded MJPEG, and the BSP decisions I'd make again.
