public.resource.org has created a mirror of NTIS.Gov's [National Technical Information Services] store that sells public domain materials. Our twist is that instead of sending you the materials, we'll release them back into the public domain for everybody to use. We mashed some of the materials up in a little infomercial here.Link (Thanks, Carl!)
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.
