theodp writes "In June 2009, Google welcomed James Whittaker as its newest Test Director. In February 2012, Whittaker rejoined Microsoft. On Tuesday, Whittaker explained why he left Google: 'The Google I was passionate about,' Whittaker writes, 'was a technology company that empowered its employees to innovate. The Google I left was an advertising company with a single corporate-mandated focus ...The old Google was a great place to work. The new one? -1.' Welcome to the real world, quips CNET's Charles Cooper in response to Whittaker's still-awesome-even-if-a-tad-naive rant." More from from his post: "It turns out that there was one place where the Google innovation machine faltered and that one place mattered a lot: competing with Facebook ... Google could still put ads in front of more people than Facebook, but Facebook knows so much more about those people. Advertisers and publishers cherish this kind of personal information ... Larry Page himself assumed command to right this wrong. Social became state-owned, a corporate mandate called Google+. It was an ominous name invoking the feeling that Google alone wasn't enough."

markass530 writes with this from the EE Times: "Arm Holdings chief executive officer Warren East told EE Times Wednesday that servers based on ARM multicore processors should arrive within the next twelve months. The news confirms previous speculation stemming from Google's acquisition of Agnilux and a recent job advertisement posted by Microsoft. East said that the current architecture, designed for client-side computing, can also be used in server applications."

Astronomers from UC Berkeley have identified 33 pairs of waltzing black holes, closing the gap somewhat between the observed population of super-massive black hole pairs and what had been predicted by theory. "Astronomical observations have shown that 1) nearly every galaxy has a central super-massive black hole (with a mass of a million to a billion times the mass of the Sun), and 2) galaxies commonly collide and merge to form new, more massive galaxies. As a consequence of these two observations, a merger between two galaxies should bring two super-massive black holes to the new, more massive galaxy formed from the merger. The two black holes gradually in-spiral toward the center of this galaxy, engaging in a gravitational tug-of-war with the surrounding stars. The result is a black hole dance, choreographed by Newton himself. Such a dance is expected to occur in our own Milky Way Galaxy in about 3 billion years, when it collides with the Andromeda Galaxy."

A post on the Left 4 Dead blog shares details of the Survival Pack downloadable content due out next week. It will be free, and available for both the PC and Xbox 360 versions of the game. "Our goals for Survival Mode are to deliver a mode of play distinct from Campaign or Versus, have games that regularly last under ten minutes, and emphasize competition with team play through leaderboards. Survival Mode draws on the planning and communication aspects of a successful Finale or Crescendo event, while taking it to another level. It rapidly hits a fever pitch that only a well coordinated team will be able to successfully survive. ... Given the extreme pace of Survival Mode, the number of zombies killed in a single round often outnumbers an entire campaign."
