hydra

Nix seems great for build servers. This is a great introduction to the motivations behind it. I'm not sold on using it for managing developer environments (another use case it is often used for). It "solves" the problem that developers might be using different versions of libraries or compilers on their machines... but it comes at the cost of having to learn a whole new programming language, a configuration language, a whole new jargon, and workflow. It's a bit like using Docker as a development environment. It introduces a non-trivial amount of friction. Some folks get excited about package management and configuration. Personally I don't care for it enough to over-come such a high learning curve. And I don't particularly like the workflow it enforces. However it is pretty great for reproducible CI/CD systems like Hydra: https://github.c
