At long last, here's video of the Cambodian bamboo railroad I wrote about in 2006; this being a homebrew railroad running at 40km/h off an electric motor, along decrepit and degenerating rails that only see one scheduled train per week. It's a pretty amazing ride.
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.
