I've written a sequel to my talk The Coming War on General Purpose Computing, called "The Coming Civil War Over General-Purpose Computing," which I'll be delivering twice this summer: first on July 28 at DEFCON in Las Vegas, and then on July 31 in San Francisco at a Long Now Foundation SALT talk, jointly presented by the Electronic Frontier Foundation. As far as I know, both talks will be online, along with slides (a rarity for me -- I normally hate doing slides, but I had a good time with it this time around).
I write books. My latest is a YA science fiction novel called Homeland (it's the sequel to Little Brother). More books: Rapture of the Nerds (a novel, with Charlie Stross); With a Little Help (short stories); and The Great Big Beautiful Tomorrow (novella and nonfic). I speak all over the place and I tweet and tumble, too.
