Ylixir's Updating Nix packages

I’ve been slacking on my Nix learning. I finally looked up how to update dev environments (all environments actually) to minty fresh versions. Simply run the following commands:

$ sudo nix-channel --update
$ nix-env -u

And that’s it. Now you will have the newest versions of all your stuff next time you run

$ nix run -f shell.nix
