When managing systems we often use imperative tools. We run commands and mutate state. Nix provides tools to convert imperative commands into functions. By using functions we gain code reuse, reproducibility and atomicity.

Nix’s tooling consists of a programming language, a package manager and an operating system. Using these tools we can define packages, cross-compiled binaries, chroot environments, virtual machines and Docker images.

This talk will skip the basics of how to use Nix and instead cover the basics of how Nix works, some of the benefits it gives and how I’ve been using it personally and professionally over the past few years.
