Earlier today, I tried to run a simple nix tool a colleague made. 3 hours into the build, it crashed. Something about a missing python import? I ran the exact same ‘nix develop’ again. 2 hours later, it worked.

Keep in mind: this was just a simple rest server. But for some reason it needed to (nondeterministically) build the word from scratch to send that single request.

I’ll take a docker system thank you.
