Ask HN: What is the best rails-cast-like site for other languages/frameworks?

I absolutely love the pacing/timing of Railscasts. Almost every other site that emulates the episodic style of screencasts either is extremely slow (with long talking-head shots), low on content (Gophercasts), or also about ruby (Rubytapas, also great). Are there good tutorial/screencast sites for other languages that you would recommend?
