One of the first things I do any time I start a new job or enter a new repository is run Gource – it gives me an initial sense of several things:<p>* Project structure (how flat vs hierarchical is the file tree?)<p>* Which files keep being edited (likely to find bugs and/or tech debt there)<p>* Which areas different people tend to work in (eg, do they hop around a lot between client/server?)<p>And of course it is just a fun thing to watch, and usually someone will walk by and ask about what I'm looking at, then they'll come watch with me.
