According to the scant details available on 4chan and Reddit there are reports that img.4chan.org has become inaccessible from California to Texas and some reports claim as far east as Connecticut. Supposedly this is to stop a ring of pedophiles, but as one Reddit poster said it best "First the came for the pedophiles and I was not a pedophile..."
Disturbing news indeed."

Readable Nuclear Spins Advance Quantum Computing 82

eldavojohn writes, "A University of Utah researcher and his team of German colleagues have shown that it is possible, using electronics, to read data stored as nuclear 'spins'. The lead researcher in the experiment was Dr. Christoph Boehme and his team's letter is available via Nature Physics (at a cost of $18 unless you are a subscriber). This is looking to be a large advance in quantum computing because prior to this, measuring the number of spins of a single phosphorus nucleus was very difficult." From the article: "The researchers used a piece of silicon crystal about 300 microns thick — about three times the width of a human hair — less than 3 inches long and about one-tenth of an inch wide. The silicon crystal was doped with phosphorus atoms. Phosphorus atoms were embedded in silicon because too many phosphorus atoms too close together would interact with each other so much that they couldn't store information. The concept is that the nuclear spin from one atom of phosphorus would store one qubit of information. The scientists used lithography to print two gold electrical contacts onto the doped silicon. Then they placed an extremely thin layer of silicon dioxide — about two billionths of a meter thick — onto the silicon between the gold contacts. As a result, the device's surface had tiny spots where the spins of phosphorus atoms could be detected."

Wii Launches, Sells Out Peacefully 565

porcupine8 writes "Like the Playstation 3, the Nintendo Wii sold out on launch day this weekend. Unlike the PS3, the launch was a peaceful affair with no reports yet of console-related violence in the US. This may be partially due to the fact that Nintendo promises to have a total of four million units in stores by Christmas, with the bulk of those going to North America. Midnight launch parties on both the east and west coasts ushered the new console in with a bang." Please, if you've managed to snag a Wii yourself, share your opinions below!

Numeric stability is probably not all that important when you're guessing.
