I don't remember how I got into this situation, but the neighborhood kids and I were sitting around my computer when I was about 7 or so. We were on some AOL-like chat program -- compuserve, maybe?

TJ typed something, and someone asked him to take off the caps. He looked confused for a moment and then took off his hat. I shrugged, having no idea what it meant either.

Another one: There was an incredible video associated with http://developer.amd.com/wordpress/media/2012/10/Tatarchuk-I... that inspired some of my graphics programming career. Unfortunately it seems lost with time.
