The European Union has fined Microsoft €561 million ($733 million) for breaking a pledge to offer personal computer users a choice of Internet browsers when they install the company's flagship Windows operating system. The penalty imposed by the EU's executive arm, the Commission, is a first for Brussels: no company has ever failed to keep its end of a bargain with EU authorities before.
The term "big data" is defined as a huge amount of digital information, so big and so complex that normal database technology cannot process it. The open-source software framework Apache Hadoop is a user-friendly approach for accessing vast amounts of data, but it is not able to query big datasets as efficiently as database systems that are designed for parallel processing. Researchers have recently introduced an aggressive indexing library for Hadoop that answers queries up to 100 times faster.

Apple’s newest iMac computer line, which went on sale last week, has something in common with world of shipbuilding. Refined for use in constructing vessels by the Office of Naval Research, friction-stir welding is responsible for the enabling the design of the iMacs. The process uses heat and pressure to join metals, and is used to achieve an extra-thin aluminum-bodied computer.
Toyota Motor Corp. is testing car safety systems that allow vehicles to communicate with each other and with the roads they are on in a just completed facility in Japan. The size of three baseball stadiums, the Intelligent Transport System site hosts a fleet of cars that receive information from sensors and transmitters installed on the streets. The sensors help to minimize the risk of accidents in situations such as missing a red traffic light, cars advancing from blind spots, and pedestrians crossing the street.
Over the course of two weeks this fall, computer models made a startling sequence of correct and useful predictions. By running thousands of simulations on polling data, Nate Silver correctly forecasted how all 50 states would vote for president. In the case of Hurricane Sandy, meteorologists identified the potential danger to the Northeast nearly a week before the storm arrived. Computer models of many kinds have improved in recent years, and the approach is finding new, unexpected uses.
According to the Top500 list, the semiannual ranking of computing systems around the world that was announced Monday morning, Oak Ridge National Laboratory’s Titan is now the world’s most potent supercomputer. It eclipses the most recent top performed, Lawrence Livermore National Laboratory’s Sequoia, with a speed of 17.59 petaflops in testing. The Titan is a Cray XK7 hybrid system, built from 16-core processors equipped with graphic processing unit (GPU) accelerators.
Most electronic data is stored on magnetic hard drives that cannot simply be enlarged to store more data. The required spinning speed for larger sizes strains components. Researchers in Singapore report that an alternative technology, heat-assisted magnetic recording (HAMR), is now a significant step closer to commercial realization. The method has the potential to double storage capacity for a given hard drive.
At IBM, scientists have for the first time precisely placed and tested more than 10,000 carbon nanotube devices in a single chip using mainstream manufacturing processes.
