We have gone through a lot when it comes to configuring our computers with Java, with an editor, and maybe even setting up Git. We often take great care in ensuring that our PATH and even JAVA_PATH environments are clean and organized. Then, when we decide to install software that depends on the software that we already have installed, what does it do, reinstall that dependency! Not only that, it’s somewhere else. Now we have multiple Java’s with the same version. We have multiple pythons, Multiple everything. It’s time to end this madness and aggravation and nix the old way and introduce the new way, NixOS.
