Supercomputer cracks sixty-trillionth binary digit of Pi-squared, gets beaten up by normal computers

Pencils down, everyone. IBM's "BlueGene/P" supercomputer has beaten you to the sixty-trillionth binary digit of Pi-squared after only a few months -- at one quadrillion calculations per second. Running thousands of independent processors, the number-crunching monster accomplished what would have taken a single CPU 1,500 years. A cloud-computing effort last year calculated Pi itself out to the two-quadrillionth digit, but you may wonder why this all matters. "What is interesting in these computations is that until just a few years ago, it was widely believed that such mathematical objects were forever beyond the reach of human reasoning or machine computation," said one researcher, "Once again we see the utter futility in placing limits on human ingenuity and technology." So there's that. But in all the commotion no one seems to have announced whether the landmark digit was a one or a zero: all you betting on the outcome will have to dig deeper into the source link.

Manual for Alienware M11x with Sandy Bridge confirms NVIDIA GT540M graphics

If the previous Alienware M11x R3 spec leak got you all giddy, then we have some good news for you: according to a manual dug up by one of our eagle-eyed readers, it appears that this year's M11x refresh will indeed be coming with second-gen Core i5 ULV and Core i7 ULV options, along with a faster DDR3 bus (1333MHz instead of 800MHz), a higher-res webcam (2MP instead of 1.3MP), an HD TrueLife LCD, and optional 3G / 4G mobile broadband. But of course, the real meat on this laptop is its graphics card, which turns out to be an NVIDIA GeForce GT540M with either 1Gb or 2GB of dedicated memory -- not bad for a laptop of this size. Unsurprisingly, no dates or prices are mentioned here, but given the early start of inventory clearance, it shouldn't be long before Round Rock reveals all. Dell (ZIP)

IBM shows off Smarter Traveler traffic prediction tool

Traffic alerts on GPS devices may be old hat at this point, but there's obviously still plenty of room for improvement, and IBM now says it's managed to do just that with its new "Smarter Traveler" traffic prediction tool. Developed with the help of UC Berkeley's transportation group and the California Department of Transportation, the tool relies on predictive analytics software, GPS monitoring and sensors already on the roads to not only offer alerts, but build a model of each person's usual commuter route. Once the system is trained a bit, commuters are able to check out what's effectively a forecast of their entire route before they even leave the house, rather than simply be alerted to traffic problems before it's too late to avoid them. Head on past for the complete press release, and a quick video explanation of how it works.

Sony Ericsson Xperia Neo delayed to Q3, Arc and Play facing limited supply due to Japanese quake

There hasn't been much good news coming out of Japan lately and this sadly keeps up with the unhappy trend. Sony Ericsson has officially bumped the broad launch (it's already available in limited quantities) of its Xperia Neo handset to at least July, explaining the delay as the result of "supply chain disruptions." Additionally, the Xperia Arc and Play devices, two other members of the company's new Android Gingerbread family, will be available in smaller volume than expected, at least for the near term. We guess that might go some way to explaining why the Xperia Play failed to reach some UK carriers in time for its April 1st launch date. Skip past the break for a statement from Sony Ericsson, who promises to be more explicit about the situation when it delivers its latest quarterly results on April 19th. As Sony Ericsson continues to assess the impact of the situation in Japan on its business, we have communicated to our operator customers and dis...
