I agree that adding every package to my NixOS configuration isn't the right way to do things, and I should definitely use a devshell or nix-shell -p $package for that. However, it's much more noticeable when I'm working with something like an HTTP server, constantly adding new things to the config, and needing to wait 25 seconds to actually test it.
It varies by day. Some days, I rebuild the system flake five times, while other weeks I don't rebuild it at all. However, the time it takes to rebuild remains about the same.
I like how they monetized their API and data because they don't want it to be used to train AI models, and now they are selling user data for millions to OpenAI.
why?
