I did https://www.udacity.com/course/cs101 Intro to Compsci and cs253 Web Dev. cs253 in particular is good, taught by Steve Huffman who built Reddit. They are fairly easy and probably at a simpler level than MIT/Stanford type stuff. Huffman's is more of a practical guide to building scalable sites rather then academic stuff.
I strongly recommend CS253. The course has just the right level of depth. Unless it's changed, it uses Google App Engine, but don't worry about that because it teaches you all the concepts about web development that you need to know to move on. This course was one of the biggest things that led to me becoming a professional developer (the other was http://www.ccs.neu.edu/home/matthias/HtDP2e/ although I didn't finish it completely)
