You can find everything here....
This has been going around the Internet, mainstream press. If you haven't seen it, it's worth taking the time to see the lecture all the way through, including after he stops presenting, then go read the followup stuff about his medical news.
Sometimes we all get too tied up in the work, and the tech, and forget the point is we are here to tell the truth, and have fun.
I won't spoil the lecture video but I will give a shoutout about Electronic Arts' new scholarship for an undergraduate woman to study computer science and video games because "the number of women entering computer science keeps dropping like a rock." That is awesome, and only a small part of this guy's legacy.
I'll come back with some Plucky stuff when I stop having my world rocked by this lecture.
