That's a great story! Thanks for taking the time to answer my question. You make good points. I've experienced links not working. In fact, Berkeley's AI course (https://berkeleyai.github.io/cs188-website/ https://berkeleyai.github.io/cs188-website/) includes 3 contests but the server no longer accepts submissions for testing let alone actually competing against other students. There have to be a lot of other people like you and I out there reading textbooks and looking at OCW but never talking to each other. A simple discord server for MIT OCW would be something. I'm currently frustrated because I'm working through the text, lecture notes and problem sets for MIT 6.045J: Automata, Computability and Complexity[0]. But there are no solutions to the problem sets! It's a proof based course and I just want to sanity check if my logic is actually valid.
