For those interested in learning, re-learning, expanding knowledge, or those just curious by nature the following lectures are very simple to digest. The primary focus is on using agile programming concepts in a simple environment (read; Python, Subversion, cygwin/unix) . A brief look at on the homepage the lecture listing will give you a healthy idea of what is covered.

The result? Most spend far too much time wrestling with software, instead of doing research, but have no idea how reliable or efficient their programs are.
