If you’re a Ruby programmer and you’ve never directly used Rack before then this screencast is for you. This introduces you to the very basics of Rack.

If you’ve used Rack before and / or you’ve very comfortable with the basics, watch for some additional Rack screencasts coming from me. I hope to make a good mini-series of screencasts about Rack awesomeness.
