@liw@toot.liw.fi Lots of good advice in this thread. Other miscellaneous things I've used successfully: * Fix something simple and debug it when it doesn't work. Repeat until things start to make sense. * Often you need to know how something is used. Don't underestimate low-tech approaches. Set a breakpoint or print something loud and run tests until you hit it, or just deliberately break it and see what else breaks as a result. * Use VCS history. `tig -Sthing` is a superpower.
