Theosis sends word that an astronomer at the University of Rochester and his colleagues have made the surprise discovery that Alcor, one of the brightest stars in the Big Dipper, is actually two stars; and it is apparently gravitationally bound to the four-star Mizar system, making the whole group a sextuplet. This would make the Mizar-Alcor sextuplet the second-nearest such system known. The discovery is especially surprising because Alcor is one of the most studied stars in the sky. The Mizar-Alcor system has been involved in many "firsts" in the history of astronomy: "Benedetto Castelli, Galileo's protege and collaborator, first observed with a telescope that Mizar was not a single star in 1617, and Galileo observed it a week after hearing about this from Castelli, and noted it in his notebooks... Those two stars, called Mizar A and Mizar B, together with Alcor, in 1857 became the first binary stars ever photographed through a telescope. In 1890, Mizar A was discovered to itself be a binary, being the first binary to be discovered using spectroscopy. In 1908, spectroscopy revealed that Mizar B was also a pair of stars, making the group the first-known quintuple star system."

twitter writes "Recent and controversial benchmarks for Windows 7 leave an important question unanswered: 'Is it faster than GNU/Linux?' Here, at last, is a benchmark that pits Ubuntu, Vista and Windows 7 against each other on the same modern hardware. From install time to GUI efficiency, Ubuntu beats Windows and is often twice as fast. Where Windows 7 is competitive, the difference is something the average user would not notice. The average GNU/Linux user is now getting better absolute performance from their computer as well as better value than the average Windows user."

An anonymous reader writes "The Windows Vista SideShow technology shows some promise. But what about Linux devices that can present snippets of information independent of the main display? Here's a review of the picoLCD-4x20, a relatively inexpensive USB device ($50) that supports both SideShow on Vista and LCDproc on Linux."

jfruhlinger writes "Think today's world, where Apple is the innovative underdog, Google is the company that does no evil, and Microsoft sits atop its throne as ruler of an evil empire. Will this state of affairs last forever? You must not remember the days when everybody loved that scrappy upstart Bill Gates. Don Reisinger muses on the fickleness of consumer loves and hates. 'It's that same [level of] success and its own questionable privacy practices that will lead to Google's PR downfall and propel it into a position of disdain going forward. Trust me, the future of Apple and Google may look bright from an economic standpoint, but these companies will be hated one day too. Sad, but true.'"

An anonymous reader sends the story of the rediscovery of an original painting of Ada Byron at about age 4, the girl who was to become Countess Lovelace and the world's first computer programmer. A US Army sergeant in Tajikistan caught wind of an eBay auction of a 180-year-old painting of Ada Byron, with provenance; he notified a programmer buddy in Texas, who won the auction.
