I love how the CommonMark Spec has a test suite that's just a JSON array. It's really easy to test a library for compliance, and I've seen developers nerd-sniped into full compliance. https://spec.commonmark.org/0.31.2/spec.json

LLMs seem to handle dependency upgrades really well. The task is well-specified, there's usually a build/test suite to check correctness of the modifications, and there's often a changelog they can consume too.

It's really satisfying to use a profiler for the first time on a project. I always find a big performance win with only a small code change. It's never the code that I expected to be slow, however!
