@b0rk I remember a post (probably on Twitter) that said roughly “lots of debugging advice says to form a specific hypothesis and test it, but I often find that’s not how I operate, I’m often exploring what’s going on without having a specific hypothesis” and I thought it might have been your post. Does that sound like a thing you said (not asking you to find the post for me). There’s a bit about exploring and figuring out one fact in The Pocket Guide to Debugging, but nothing quite like that.
