I am not sure this is the right place to post this, but I took this class (not for a grade) just to listen to the lectures and there was a lot of good concepts that have helped me in using the SNC platform.
I just recently gave a presentation about Unit Test in SNC and we are in the process of building a plugin to support TDD (Test Driven Development). I stole some of the concepts and ideas from this course.
I ignored the Ruby part, but I found it useful to set up my own Amazon EC2 image. I use this now to do proof of concept integrations.
