I don't have any context for this 1901 map of undersea cables for the Eastern Telegraph Company System, but it sure is a tantalizing look at telcoms history and the way that the world used to talk to itself.
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.
