waiting 30 minutes an AUR makepkg to download 800Mb of god-knows-what from a weird German FOSS hosting service to build tenacity from source only to have it fail

then type "nix-env -iA nixpkgs.tenacity" and blink while it pulls from the s3 cache of precompiled binaries and tenacity 1.3.1 is running 3 seconds later

nix is magic
