Watching Notch's code stream "Making Prelude of the Chambered" (http://www.youtube.com/watch?v=rhN35bGvM8c&t=10m05s&hd=1) was fascinating.
Are there any other sites like WatchMeCode.net. I'd like to watch developers screencast their workflows, especially for different languages. Watching a top OSS contributor work (jumping from IDE, to test, to GitHub) would be awesome.
PeepCode has a series called "Play by Play" (https://peepcode.com/screencasts/play-by-play) where you can see a lot of professionals solve a small problem in 1-2 hours. It goes through their thought process, design and implementation. I think I've seen Ruby, JS, Python and even C in some of those screencasts.
