TekPub streams are mostly javascript. I'd like to see ruby devs at work. It struck me over the weekend as I was working on some 24 Pull Request projects. We should not only share our code, but our process as well.

Edit: RailsCasts are awesome, and episode 300 (http://railscasts.com/episodes/300-contributing-to-open-sour...) is a great example. Any others?
