I really like how Josh Vickery put together this iPhone tutorial. Really clear cause and effect walkthrough of how you can connect a Ruby application with an iPhone application using the Objective Resource framework. I don’t even know Ruby and I still enjoyed the video. Something about watching someone explain code through video, or in person, that helps understanding, and is often lost when reading tutorials or technical manuals. The human element makes it seem not quite as daunting. See, not all code is written by robots, there is usually a human behind the scenes pushing all the buttons.
