Good morning. Another day. Another opportunity to chose real girls over virtual girls. Can't have both. Reminds me of the part of Noah book where he writes about 3 paths. 1 Path: PMO as usual, 2 Path: No-P at all, and 3rd Path: middle of the road, you know P is bad for you but you'd still like to indulge from time to time. Paraphrasing a bit. I see it clearly now. P and real life are mutually exclusive. I can have one but not both. Things are a lot simplified now. Yesterday, was another P free day. No bullshit. @SB yeah, Coursera is great, give it a try. It is free with a few caveats. Recently only if you pay for a course you can submit assignments for grades. So in effect you are free to have all the course materials just not free to grade the assignments.
