On my way to San Diego I stopped by San Francisco. I met up with some of the people at the EFF and Seth Schoen demonstrated the research they’ve been doing into printers that spy on you. Unfortunately I did not have much time in San Francisco, but I did get to visit the Exploratorium.
I will try to get back to everyone who has emailed me recently. If you haven’t received a response by Monday, feel free to resend your email.
