Well, so much for Open Source software development. On the heels (literally) of its latest released version of Ubuntu, Mark Shuttleworth has announced that parts of the development of the 13.04 build, codenamed Raring Ringtail, will be done in secret away from the scrutiny of Ubuntu’s critics.
As for what these secret features actually are, Shuttleworth says that Canonical’s skunkworks project (so called after Lockheed’s secretive R&D Skunk Works department) has something for everyone, from "webby, to artistic, to scientific, to glitzy, to privacy-enhancing, to analytical."
