Today's XKCD, the "Eyelash Wish Log," is a bit of design fiction that implies the story of a too-clever-for-his-own-good protagonist who tries to hack the rules and regulations of wishing. It reminded me of Stephen Gould's excellent YA novel Jumper, which rigorously and thoroughly maps out the possibilities of teleportation (which was adapted into a movie that, unfortunately, omitted most of its charm).
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.
