Nitin Chandrachoodan and I teach the Modern Application Development course at IITM as part of the Online BSc Degree program. In part one of this course, Nitin handles theory, and I run all the lab parts. Here are the screen-casts from my sessions. You will need a computer with some tools installed (mentioned in the screen-casts) if you want to work along with me. I have a separate page for Modern Application Development - 2, in case you were looking for that.
