Submission + - Robot models itself and learns to walk

user24 writes: "Josh Bongard, Victor Zykov, and Hod Lipson of Cornell have created a self-modelling robot.
From TFA: "We have demonstrated how a physical robot can create an "internal model" of itself, and then use that model to generate successful motor patterns for locomotion, before and after damage. Most current robotic systems plan their behavior using a built-in mathematical model whose from is provided externally by engineers. Some robots can adapt without a model, but require many physical trials. Our result shows that a machine can adapt without being given a model and without extensive trials, by gradually developing an internal model of itself."

Submission + - Jimmy Wales resigns chair at wikipedia

user24 writes: "As reported by Wikipedia's Signpost ezine, "The Wikimedia Foundation Board of Trustees has moved forward with a step in restructuring the organization by reorganizing itself. Following a planning retreat in Frankfurt, Jimmy Wales stepped down as Chair of the board, and Florence Nibart-Devouard was chosen to replace him." ... "Wales, meanwhile, will continue to serve on the board and assume the honorary title of Chairman Emeritus. He will remain active in Wikimedia projects, but chose to pass on the responsibility of heading the board, due in part to his commitments to outside projects.""

Submission + - defending against quantum attacks

user24 writes: "Security Focus is running a story that may be a little ahead of it's time;

"In the weird world of quantum computing, the state of computer systems networked together is so fragile that a read access to a single quantum bit, or qubit, on one machine would require a network-wide reset."

"I want to maintain the quantum computer in a good state until, magically, the answers appear. Stray cosmic rays and things like that — if they interact with this stuff, then something changes and the computer crashes. The thought is that people could do that on purpose.""
