Debian SID is a code name which stands for Still In Development. Sid is the kid next door, he breaks his toys and makes nasty creatures of them. He's also the miner in Toy Story 2. He's so nasty he'll never be released! ;-)

While other release code names (such as Potato or Woody) progress in time from being DebianTesting to being DebianStable, Sid is forever doomed to being DebianUnstable.
