NixOS has been my daily driver since 2022/2023 and I have greatly improved the management of my 2 computers and few VMs since. Because of LLMs, I now understand the language much better, but even if I didn't want to write Nix directly, describing the config to AI usually produces good results.

The two main sticking points IMO are still:

- Development environments are still a pain. devenv.sh is great for web and backend, but not perfect for dependency (package) management and more complicated environments like mobile or embedded

- nixpkgs monorepo doesn't update fast enough IMO. As a consequence, I see a number of flake repositories popping up to more easily package and distribute software not yet on nixpkgs or that don't update often enough (https://github.com/numtide/llm-agents.nix is a good example). This is perhaps by design, but it takes some digging to find the reliable and trustworthy flake repos. I'm increasingly concerned with AUR-like trust issues

Weird, development environments are one of my favorite things about nix. I don't use anything like devenv.sh, just add a `flake.nix` to the repo defining a devShell, and then add `use flake` to `.envrc` and let direnv activate it. Every major and most minor editors have support for direnv, and if they don't, you can just launch them from a shell in that directory. This makes the only system dependencies for a great dev environment nix and direnv.

Once you've done it a few times, most things are pretty easy to package yourself, and you can just check those derivations into your git repo for your machines and use them. Especially if you're using LLMs, it shouldn't be all that hard to package what you need in most cases. For stuff that's more complicated or difficult, it's more likely there will be some kind of de facto standard flake for it.

Is devens something else than nix shell?
