The iPad Will Get Playboy In March 223

Posted by samzenpus from the clean-the-screen dept.
Stoobalou writes "Playboy boss Hugh Hefner has confirmed that — despite Steve Jobs' protestations that Apple is pure and Android is for porn — an app for browsing uncensored back issues of Playboy is to launch later this year on the iPad. The news, which is likely to generate significantly more buzz for Apple's popular tablet as a publishing device than Rupert Murdoch's delayed digital newspaper The Daily, comes courtesy of Hefner's Twitter stream, in which he proclaimed: 'Big news! Playboy — both old & new — will be available on [the] iPad beginning in March.'"

New Sunlight Reactor Produces Fuel 269

Posted by CmdrTaco from the summon-danny-boyle dept.
eldavojohn writes "A new reactor developed by CalTech shows promise for producing renewable fuel from sunlight. The reactor hinges on a metal oxide named Ceria that has very interesting properties at very high temperatures. It exhales oxygen at very high temperatures and inhales oxygen at very low temperatures. From the article, 'Specifically, the inhaled oxygen is stripped off of carbon dioxide (CO2) and/or water (H2O) gas molecules that are pumped into the reactor, producing carbon monoxide (CO) and/or hydrogen gas (H2). H2 can be used to fuel hydrogen fuel cells; CO, combined with H2, can be used to create synthetic gas, or "syngas," which is the precursor to liquid hydrocarbon fuels. Adding other catalysts to the gas mixture, meanwhile, produces methane. And once the ceria is oxygenated to full capacity, it can be heated back up again, and the cycle can begin anew.' The only other piece of the puzzle is a large sunlight concentrator to raise the temperature to the necessary 3,000 degrees Fahrenheit. The team is working on modifying and refining the reactor to require a lower temperature to achieve the two-step thermochemical cycle. Another issue is the heat loss which the team claims could be reduced to improve efficiency to 15% or higher. Since CO2 is an input, the possibility exists for coal and power plants to collect CO2 emissions to be used in this process which would effectively allow us to "use the carbon twice." Another idea listed is that a "zero CO2 emissions" is developed along these lines: 'H2O and CO2 would be converted to methane, would fuel electricity-producing power plants that generate more CO2 and H2O, to keep the process going.' The team's work was published last month in Science."

Yahoo IPv6 Upgrade Could Shut Out 1M Users 290

Posted by CmdrTaco from the trial-by-fire dept.
alphadogg writes "Yahoo is forging ahead with a move to IPv6 on its main Web site by year-end despite worries that up to 1 million Internet users may be unable to access it initially. Yahoo's massive engineering effort to support IPv6 — the long-anticipated upgrade to the Internet's main communications protocol — could at first shut out potential www.yahoo.com users due to what the company and others call 'IPv6 brokenness.'"

How Facebook Ships Code 314

Posted by CmdrTaco from the wish-i-had-hundreds-of-engineers dept.
Hugh Pickens writes "The two largest teams at Facebook are Engineering and Ops, with roughly 400-500 team members each, together making up about 50% of the company. All engineers go through 4 to 6 week 'Boot Camp' training where they learn the Facebook system by fixing bugs. After boot camp, all engineers get access to the live DB and any engineer can modify any part of Facebook's code base and check-in at-will so that engineers can modify specs mid-process, re-order work projects, and inject new feature ideas anytime. Then arguments about whether or not a feature idea is worth doing or not generally get resolved by spending a week implementing it and then testing it on a sample of users, e.g., 1% of Nevada users. 'All changes are reviewed by at least one person, and the system is easy for anyone else to look at and review your code even if you don't invite them to,' writes yeegay. 'It would take intentionally malicious behavior to get un-reviewed code in.' What is interesting for a company this size is that there is no official QA group at Facebook but almost every employee is dogfooding the product every day."

The Fall of Wintel and the Rise of Armdroid 431

Posted by Soulskill from the upgrading-the-portmanteau dept.
hype7 writes "The Harvard Business Review is running a very interesting article on how this year's CES marked the end of the Wintel platform's dominance. Their argument is that tablets are going to disrupt the PC, and these tablets are predominantly going to be running on Google's Android powered by ARM processors — 'Armdroid.' Quoting: 'Both Microsoft and Intel have suffered from the same problem that most successful companies face when dealing with disruption. They cannot find a way to profitably invest in low-end offerings. Think about it from Microsoft's point of view: now that Windows 7 has been developed, to sell another copy, they don't have to do a single thing. Because of this, it becomes very hard for any executive to advocate the complete development of a low cost OS that will run on tablets: not only would it cost Microsoft a lot to develop, but it would result in cannibalization of its core product sales. Intel has the exact same issue. Why focus on Atom, or an even lower-end chip, when there is so much more margin to be made by focusing on its multi-core desktop processors?'"

DoE Develops Flexible Glass Stronger Than Steel 242

Posted by Soulskill from the whale-tested,-scotsman-approved dept.
An anonymous reader writes "The Department of Energy Office of Science recently collaborated with the Lawrence Berkeley National Laboratory and the California Institute of Technology to develop a resilient yet malleable new type of glass that is stronger than steel. The material can also be molded, and it bends when subjected to stress instead of shattering. The glass is actually a microalloy and features metallic elements such as palladium. This metal has a high 'bulk-to-shear' stiffness ratio that counteracts the intrinsic brittleness of glassy materials. The team that developed the material believes that by changing various ratios, they could make it even stronger."

Man Tunnels Into GameStop, Steals Games 210

Posted by CmdrTaco from the digging-for-treasure dept.
An anonymous reader writes "Life imitates Minecraft: Computer game piracy is big business, but there are still those who prefer to get their games the old-fashioned way: by digging a tunnel into their local games shop and making off with as much stock as they can carry. At least, that's the slightly bizarre approach taken by a man from Greeneville, Tennessee, who was arrested late last week after being caught tunneling into his local GameStop store from an empty adjoining building."

Dating Site Creates Profiles From Public Records 257

Posted by timothy from the you-didn't-even-know-you-were-looking dept.
schliz writes "Online dating company Gotham Dating Partners has announced plans to create profiles for non-registered individuals based on publicly available information from social networking sites, e-mail registries, mailing lists, marketing surveys, government census records, real estate listings and business websites. Although the Australian Privacy Commissioner has warned that the automatic creation of identifiable profiles of individuals without their knowledge is 'not good privacy practice,' Gotham Dating Partners does not expect to face any privacy issues from the move, which is expected to boost its membership from 6.5 million to 340 million worldwide."

Xfce 4.8 Released 193

Posted by timothy from the when-snappy-matters dept.
PerlDudeXL writes "Today, after almost two years of work, we have the special pleasure of announcing the much awaited release of Xfce 4.8, the new stable version that supersedes Xfce 4.6. [..] Xfce 4.8 is our attempt to update the Xfce code base to all the new desktop frameworks that were introduced in the past few years. We hope that our efforts to drop pieces like ThunarVFS and HAL with GIO, udev, ConsoleKit and PolicyKit will help bringing the Xfce desktop to modern distributions."

Cassandra 0.7 Can Pack 2 Billion Columns Into a Row 235

Posted by timothy from the but-only-if-they're-really-thin dept.
angry tapir writes "The cadre of volunteer developers behind the Cassandra distributed database have released the latest version of their open source software, able to hold up to 2 billion columns per row. The newly installed Large Row Support feature of Cassandra version 0.7 allows the database to hold up to 2 billion columns per row. Previous versions had no set upper limit, though the maximum amount of material that could be held in a single row was approximately 2GB. This upper limit has been eliminated."
