Thanks! I've submitted a paper to Black Hat / DefCon; I don't know if it'll be accepted. If so, I'll have fun doing a talk there.
I'm volunteering around the Bay Area (up at the Steam Trains at Tilden Park on Sunday afternoons), show up to the intro-classes at Berkeley Folk Dancing, and speak to schools and professional groups.
And, of course, I'm still operating this Klein bottle business. I have only one employee (who is a lazy, good for nothing sloth). Management is very thin and incompetent: there's only one boss (who is an oppressive taskmaster always trying to get me to do more work than I want to).
