TIL Advent of Code and Project Euler will deliberately look for puzzles where the naive solution is worse than quadratic. This ensures that people can solve them with any programming language. You don't want fast languages to be able to use the naive solution.

Has anyone built a great solution to 'run all my unit tests automatically'? It's straightforward to write a while loop in bash, but handling timeouts, syntax errors etc well is hard. Running on save would be good, although I wonder if you could run fast tests on each keystroke.

I find myself using a "splatter then clean up" technique when working with code. I add a ton of prints/logs/asserts/type annotations until I've found the issue. I then throw them all away! It feels like redundant work, but I don't have a nicer solution.
