Ways for reading open source code bases?
nostrademons: Google Code Search:http://www.google.com/codesearchI use it for working my way around Google's codebase, which is a few orders of magnitude bigger than that.Also, there's no substitute for getting your hands dirty and diving into the code.  You don't really understand something until you've changed it a few times.  Grab a couple of low-priority bugs and write some patches for them; you'll learn far more than if you just sit down and study things.
