The Nix Hour

The Nix Hour is a weekly beginner-oriented improvised QA-style lecture on Nix, hosted by Tweag. Here you can bring your questions and we'll answer them with more context, examples, alternatives, tradeoffs and related topics. These meetings are open for anybody to join, but also recorded and uploade…
