The National Security Agency has released an archive of back issues of Cryptolog, its secret, in-house magazine, in a repository spanning 1974 to 1997. The issues are heavily redacted in places, but still look like a promising source of interesting and curious facts.
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.
