My First Impressions of Nix
I've occasionally encountered projects using Nix, and I've casually browsed the Nix and NixOS websites, but I still don't have a clear idea of <i>what Nix is.</i><p>Is it a package manager? A build system? An operating system? A container platform? A sandbox? An automation tool?<p>Which widely used, existing software tools is it analogous to?
