NixOS

I’m very interested in the Nix package manager, NixOS Linux distribution and the ecosystem that’s emerging around them. As a seasoned user of Nix, I’ve written some (opinionated) guides and explanations:

Nix from the bottom up explains the basic underpinnings of Nix, and what it’s actually doing under the hood.
Nixlang glossary gives a rough overview of the Nix Expression Language, which can be used to specify what Nix should build.
Dependency solving in Nix shows how Nix can wrap legacy tools to build projects securely and reproducibly, including solving version constraints and resolving names to artifacts.
Nix Packages describes how Nix provides a similar user/sysadmin experience to a traditional Linux package manager.

Over the years I’ve come up with a few tricks/hacks, which may be useful to some:

Useful Nix hacks
Using Debian Packages on NixOS
Scripting with Nix
nix-eval for run-time evaluation of Haskell code
Benchmarking arbitrary projects with Nix and asv
nix-shell shebangs
Using Nix with separate stores
Nix caching on a LAN

I’ve also written some pages about various ways I’ve used Nix:

Switching to NixOS
Developing on NixOS
