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.

I'm always hesitant when I see digital services funded by a single one-off payment. Running a service requires ongoing funding. You sometimes see this with games that have a multiplayer component. People buy the game, but the multiplayer servers won't last forever.

I frequently find myself running: $ slowish $ slowish | jq $ slowish | jq | grep I feel there must be a better way to build up pipelines incrementally without re-running. I could save each output to a file, but it's more verbose, and most of these tools have nicer output when stdout is a TTY.
