Roman sez, "When I was a kid in the USSR, my parents got me a fun comic book about how robots work. It's a translation of a book by a french roboticist, and it's remarkably accurate even now (the first chapter describes a Roomba). Recently, I found it again, scanned it in, and wrote a translation into english. After getting permission from the author, I put it up online, so enjoy." Link (Thanks, Roman!)
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.
