Bruce Schneier's latest Google talk expands -- very productively -- on his recent theme of "security feudalism" (roughly, the idea that we end up trusting companies like Facebook, Apple and Google to serve as our feudal lords, securing us from marauders in exchange for being locked into them and subject to their whims). This is a lot more unfinished and unformed that the usual talks I've heard from Bruce, but that's really because he's exploring some new ways of thinking about important issues. It's an hour's watch (or listen -- there's not really any reason to tune into the video; I just ripped it to an MP3 and put it on my phone while I was walking around) but it's an hour well spent.
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.
