Nix at Mozilla

London Nixos Usergroup


What is Nix?

  • a build tool
  • a language
  • a package manager
  • extends to whole Linux distro

How to introduce Nix at work?

  • Solve your own problem first (eg. your own development environment)
  • Teach nix
  • Start to package projects as you come by them
  • Put infrastructure in place (Travis + S3 bucket is enough)
  • Teach nix
  • Volunteer to solve hard problems only Nix can solve
  • Teach nix
  • Point out problems (laud) which other tools are not considering
  • Create default.nix for all your projects
  • Time to create first PRs to share default.nix with others
  • Talk with coworkers about Nix (to remove the fear)
  • In worse case you can keep you default.nix and people will eventually look at it.
