Where's Jon? Singapore Edition

It's time for the slightly less exciting version of "Where's Waldo?" in which I try to find myself in pictures that people have posted of conferences I've attended. (I've labeled similar posts so you can view all of them here.)  The clearest shot (reproduced above) is here.  I'm also on the right in this picture from the rump session.

I have no idea who any of these other people are.  Also, I don't like fisheye lenses because they make people (in particular me) look like they have hunchbacks.
