What happens if you are the last (the very, very last) of your species, and you die - and humans notice? We live, increasingly, at a time when extinctions are recorded, remembered, and the last animal (or plant) in its line, by virtue of its being last, becomes a kind of celebrity. Its finality becomes a thing to honor.

News, after all, is a spin of words and pictures. It's a kind of music. There are beats in a newscast, a newspaper story. Ed Murrow sounded like Ed Murrow. Huntley and Brinkley sounded different. Anderson Cooper, different still.

Computers and computing are all around us. Some computing is highly visible, like your laptop. But this is only part of a computing iceberg. A lot more lies hidden below the surface. We don't see and usually don't think about the computers inside appliances, cars, airplanes, cameras, smartphones, GPS navigators and games.
