The keynote for HOPL-III by Guy Steele and Richard P. Gabriel was the best keynote, best presentation, best talk... I have ever had the privilege of attending in person or not.

I hope it was video recorded by someone so that I can relive that experience some day.

The keynote ended with a touching memoriam for computing / programming language icons who are no longer with us. It's quite something to end such an amazingly entertaining talk with something so somber, and to realize that so many people in the room were actually in tears.

Before the end of the conference I hope to get to thank them for the talk, but first I'll have to compose myself.
