App::plx (Plx) is a tool for configuring per-project Perl development environments.
Plx is not difficult to use and has very clear documentation. In this post I will give a brief overview of some of the problems that it solves and how to get started using it.

At Tweag, we write a lot of code using the Nix language. Most of that code produces derivations or packages but occasionally we write small helper functions that are algorithmic in nature. As diligent developers and when appropriate, we should write unit tests to ensure the correctness and maintainability of our code. This post will demonstrate and compare various ways available in the Nix ecosystem to add unit testing to your Nix code — specifically Nix functions.
