A sack full of angry snakes: Taming your python dependencies with Nix
summary
Claims that Nix reproduces exact Python stacks by hashing full dependency closures and compiler toolchains, can pin channels to a commit for identical builds, and produces sealed build environments that exclude undeclared files. Demonstrates integration with C libraries, generational rollbacks, and creating minimal Docker or VM images. Shows tooling like poetry2nix and mach-nix, cites Nixpkgs size (~40k packages, ~3k Python packages), and explains whether builds are repeatable and deployable.
