Nix (https://nixos.org/) is a package manager with more than 120,000 packages, an operating system with more than 20,000 options, and a build tool for creating reproducible and reliable software that works the same for everyone, every time.
In this talk, Oliver will explain what Nix is, show how to create development shells for PHP (and anything else) that mean you no longer need to use containers or virtual machines, and how to package PHP applications that are easy to deploy and distribute.
