It's a programming conference, not a meeting of the KKK.
Yes that's what happens now.

Dell comedian? Comedians thrive on controversial material. Sounds to me like a tongue-in-cheek observational joke that is just as offensive to men as it is to women. "Congratulations, the IT industry is a sausage-fest, just the way you want it to be, right?"
CouchDB? Can't find a copy of the original presentation, but what's wrong with allusions to pornography? There are plenty of male porn stars, and plenty of pornography that degrades men?
Perks: Women? Again, an observation on the male dominance of the industry. Similar to the Dell comedian, this is much a joke aimed at men as it is at women; male geeks need to attend a code jam to come into contact with women, etc.
