"What is GitHub?" you ask?
"Obviously, you're not a golfer..." - The Big Lebowski
Seriously though. It's probably the sweetest website since Google. It's a way for programmers to open-source/share/collaborate on their code.
Anyway, I use it to search the codebase of a project at work because there's over 4 million lines of code and TextMate takes forever to search it. But GitHub must index the code or something. Cause it searches it so fast! and it even allows regex search.
Try it! It's awesome!
Enjoy!
