This is from the party at the end of the Usenix 2003 technical conference.

Just to be clear (and to be kind to Jeff, who has a conservative family): this is a staged shot, and neither of them is gay (in fact, Eric Allman asked Jeff "Gay or straight?" when I was setting this up, and only proceeded after Jeff emphatically answered "straight").

Update: Eric Allman apparently actually is gay. That puts kind of an interesting twist on the question that I hadn't realized. I am a little confused now, though, because I had thought he was married to Cat Allman.
