Here's a list of interesting computer-related YouTube channels I've found which do an excellent job of describing computing concepts or are just very interesting.
I hope you enjoy watching them them...
This is a very interesting playlist from the CrashCourse channel. It describes pretty much all computer science concepts and computing history in a very friendly and accessible way.
For all the, well, computerphiles out there. Explains computing concepts, history, coding, puzzles and loads of other great stuff. This channel is presented by Brady Harran and his friend. A great guy.
The latest tech news in a "way that doesn't suck". May contain adult language.
