What are interesting, unique, and/or non-standard uses of Nix?

[toraritte]

Was able to find some of the links I lost:

• Building a reproducible blog with Nix (by @ysndr)
• Complete overkill or exactly right? Deploying a static site using nix (by @mpickering)
• nix-freeze-tree: Convert a tree of files into fixed-output derivations (see blog post also)
• Reproducible résumés (by @matthewbauer)

Update (7/18/2023):

• The repo responsible for generating the HTML for the NixOS webzine. (announcement)
