There was a sweet spot in like 2024 when it seemed like everything was possible with Nix, but now it seems like everything “experimental” is permanently so (like flakes), packages I care about are not as fresh as I want, I have no mental recall for Nix commands… Meanwhile, my company is using Nix for everything heavily internally. Everyone gets their dependencies via Nix unless you are like using PAM or something. Re…
In my mind, Nix was unstoppable, and I particularly loved how empowered I imagined developers would feel. No mystery-meat CI scripts pushing packages to distant infrastructure that no one understands or even has the permissions to interact with, just the entire build system in one repo, trivially cloneable and hackable... add patches or build steps to anything and it's the same build as always, build it locally or send it to Hydra, it doesn't matter.
A devs "got" it and did leverage those things, used PRs to do safe evaluation of bumps to core dependencies, but I think on the whole it was regarded as cool but not tractable, and a few years after leaving, it sounds like plans are being laid to replace it all with something containers or whatever.
Very frustrating, particularly in a world where it should be trivial to identify the 5-10 typical tasks that people want to do with the nix code, and set up Claude skills to handle those. Given how easy and self-contained the build-test loop is, it feels like an almost perfect fit for agent-led development.
