> For college-level technical subjects, there are also e.g. many MIT lectures on OCW. There are? I know an OCW course includes "lecture notes" pdfs. Does it have the lectures too? For example, the course "distributed systems" is available on OCW as 6.824, from spring 2006: https://ocw.mit.edu/courses/6-824-distributed-computer-systems-engineering-spring-2006/ https://ocw.mit.edu/courses/6-824-distributed-computer-syste... MIT has renumbered the course, but it's still around: https://pdos.csail.mit.edu/6.824/ https://pdos.csail.mit.edu/6.824/ . Don't be fooled by the URL; it's now 6.5840. And a series of lectures is available too: https://www.youtube.com/@6.824/videos https://www.youtube.com/@6.824/videos . They're from spring 2020. They link to the course website for spring 2020, which is great. But it doesn't link to them, and OCW doesn't know about any of this, as far as I can tell. The 6.824 lecture series is pretty hard to discover, too, because it's uploaded by an account dedicated solely to that one course, which isn't related to any other MIT lecture videos.
