Online Computer Science Courses

I knwo there are posts each month on when new classes are starting, but there is one post that I have been looking for in particular. I believe I saw it on this subreddit, but am not able to find it anywhere now.

Previously I had seen a post on a computer science/programming course catalog that showed a number of free online classes. These classes were selected to fulfill what people would generally need to complete a computer science degree at a university. I have looked high and low, but I am not able to find the particular thread. Does anybody recall this thread? Any help finding it would be greatly appreciated as I'm coming up empty in my searches.
