On the Monday and Tuesday before PyCon, Jean-Paul Calderone and I will be teaching a two-day introduction to Twisted in San Francisco. We'll be covering the basics of the event loop, Deferreds, and other core APIs, with lots of hands-on exercises. (The 3-hour tutorial I'll be teaching at PyCon includes a small part of this material.) You can learn more here: http://blog.futurefoundries.com/2013/01/2-day-twisted-class-in-san-francisco...
