"The spammers behind last year's destruction of Blue Security are back with a vengeance, using a variant of the 'Storm Worm' malware to launch a sustained distributed denial-of-service attack against three anti-spam services.
SpamhausThe ongoing attacks, which use botnets of hijacked Windows computers, successfully shut down the Web servers that power the Spamhaus Project, URIBL (Realtime URI Blacklists) and SURBL (Spam URI Realtime Blocklists (SURBL)."
Check out the castlecops forum, where members of these antispam groups are picking over the details of the attack."

Last night, he broke free of his disability and indulged his passion for gravitational phenomena in a finely stage-managed operation 32,000 feet above the Atlantic.
"It was amazing," he said after he returned from his experience of weightlessness. "The zero-g bit was wonderful . . . I could have gone on and on. Space, here I come."""

The report falsely stated that the comic passed away on the morning of March 14 due to heart failure, but the comic was found laughing about the instance the following day.""

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." Watch the video here."

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.""
"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.""
