No, no. The Christmas lecture happened this year as well (the 25th year in fact!): https://www.youtube.com/watch?v=3DKo219ZHMw&feature=emb_titl...

As is usual from Prof. Knuth, it's great with tonnes of nuggets of wisdom, especially if you are a fan of easter eggs (though his "style" of presentation bothers quite a few of my friends)! :)

It happened this year and it was packed. So much so that when I reached 10 min late, there were so many people (standing) that I couldn't actually see Knuth even though I was technically inside the Nvidia auditorium, Stanford. Could only see the overhead screen. Tried standing on my toes and kept craning my neck to no avail, so had to leave disappointed :-(

PS: I did get to attend and see him last year so that's something.
