What did I learn today

2022-01-20

• what are nixos containers and that when writing a flake for one one usually just writes "container" in place of hostname while declaring just one, so nixosConfigurations is supposed to really be always plural
• what exactly are self and super in nix overlays
• that an example of modern Perl with good practices for me could be nix-container.pl
• about recursiveUpdate
• that `nix search` now has the first argument be the flake registry
• that nvidia GPU in one of the laptops i use is now legacy for the driver in the more recent nixos channel
• i think i forgot things and maybe even imma edit, but better to post it now
