Trolling my blogs today and as reported by Tech Crunch, FaceBook source code was leaked today and it looks to be php rich. I indexed the info at http://wholesalerwholesaler.shoutpost.com/ Thanks I hope you PHP guys have fun.
Here is easier copy of the code to see. Hope you enjoy the discovery. http://facebooksecrets.blogspot.com/
It's just the index / nothing special or revealing really.. only mildly surprising thing is they're using procedural code instead of OO, but I suppose it's faster at that scale (though granted a pain in the butt for the developers)?
