MojoKid writes "Today at the Hot Chips Symposium, AMD CTO Mark Papermaster is taking the wraps off the company's upcoming CPU core, codenamed Steamroller. Steamroller is the third iteration of AMD's Bulldozer architecture and an extremely important part for AMD. Bulldozer, which launched just over a year ago, was a disappointment. The company's second-generation Bulldozer implementation, codenamed Piledriver, offered a number of key changes and was incorporated into the Trinity APU family that debuted last spring. Steamroller is the first refresh of Bulldozer's underlying architecture and may finally deliver the sort of performance and efficiency AMD was aiming for when it built Bulldozer in the first place. Enhancements to Fetch and Decode architecture have been made, as well as increased scheduler efficiency and cache load latency, which combined could bring a claimed 15 percent performance-per-watt performance gain. AMD expects to ship Steamroller sometime in 2013 but wouldn't offer timing detail beyond that."

ciaran_o_riordan writes "After two private meetings with Microsoft and IBM, New Zealand's proposed new patent legislation has been changed by 'replacing an exclusion in clause 15(3A) (which relates to computer programs) with new clause 10A. Rather than excluding a computer program from being a patentable invention, new clause 10A clarifies that a computer program is not an invention for the purposes of the Bill.' The difference is that the new 10A clause contains the 'as such' loophole — the wording that is used by the European Patent Office to grant software patents. This is the same Patents Bill launched in 2009."

tetrahedrassface writes "Slashdot carried the story of an-as-yet unverified impact crater in Tennessee a couple of years ago. After a few weeks of fairly hardcore sample taking, digging, obtaining some good images and manipulating them, I'm proud to report the first batch of evidence in favor of it being an impact site. The primary smoking gun is the presentation of an astrobleme, obtained from High Resolution Ornithographic Images taken in 2008. Also of note are the melted/deformed rocks, magnetic crater dust, and the fitment of the crater rim to a circle. A rented plane and a bunch of photographs today and it's pretty obvious that it's a crater, folks. Cheers!"

ananyo writes "On 27 August, a report by the American Academy of Pediatrics concludes for the first time that, overall, boys will be healthier if circumcised. The report says that although the choice is ultimately up to parents, medical insurance should pay for the procedure. The recommendation, coming from such an influential body, could boost U.S. circumcision rates, which, at 55%, are already higher than much of the developed world. The researchers estimate that each circumcision that is not performed costs the U.S. health-care system $313."

Zothecula writes "When the late Neil Armstrong and the crew of Apollo 11 went to the Moon, they did so sitting atop a rocket the size of a skyscraper that blasted out jets of smoke and flame as it hurtled skyward. For over half a century, that is how all astronauts have gone into space. It's all very dramatic, but it's also expensive. Wouldn't it be cheaper and easier to take the elevator? That's the question that Michael Laine, CEO of LiftPort in Seattle, Washington, hopes to answer with the development of a transportation system that swaps space-rockets for space-ribbons. LiftPort ultimately wants to build a space elevator on Earth, but the company isn't planning on doing it in one go. Instead, Laine and his team are settling for a more modest goal – building an elevator on the Moon by 2020. This is much easier. For one thing, there’s no air on the Moon, so no icing problems. Also, the lower gravity means that no unobtainium is needed for the ribbon. Kevlar is strong enough for the job. And finally, there’s very little in the way of satellites or debris to contend with."

Gunkerty Jeb writes "The Air Force Life Cycle Management Center posted a broad agency announcement (PDF) recently, calling on contractors to submit concept papers detailing technological demonstrations of 'cyberspace warfare operations' capabilities. Among many other things, the Air Force is seeking to obtain the abilities to 'destroy, deny, degrade, disrupt, deceive, corrupt, or usurp the adversaries' ability to use the cyberspace domain for his advantage' and capabilities that would allow them to intercept, identify, and locate sources of vulnerability for threat recognition, targeting, and planning, both immediately and for future operations."

An anonymous reader writes "A forensic test that has been developed to help police nab perpetrators of crimes can predict a suspect's eye color, hair color, and ethnic origin. The test's ability and the science behind it has been outlined in Forensic Science International: Genetics (abstract). Developed by Susan Walsh and other researchers from the Netherlands, Greece, and Poland, the test uses phenotypes from DNA to ... predict a suspect's appearance using 'low amounts of template DNA, as well as degraded DNA,' which means that the DNA does not need to be perfect in order for the system to read it."

New submitter Isara writes "GigaOm's Jeff John Roberts has a compelling writeup about patent trials and how juries are detrimental to justice in such cases. Roberts uses the recent Apple-Samsung trial as the backdrop for his article; although the trial lasted three weeks, during which hundreds of documents were presented and the finer points of U.S. patent law were discussed, the jury only took 2-3 days to deliberate. 'Patents are as complex as other industrial policies like subsidies or regulatory regimes. When disputes arise, they should be put before an expert tribunal rather than a jury that is easily swayed by schoolyard "copycat" narratives.'"

Mozilla released Firefox 15 today, and it brings a number of interesting changes. First, the browser is finally switching to a "silent" update model, like Chrome. (No doubt in answer to endless complaints about their rapid release cycle.) In addition, Mozilla says they have "now plugged the main cause of memory leaks in Firefox add-ons." Add-ons commonly hold extra copies of sites in memory when they don't need to, and the browser now has a mechanism to detect this and reclaim the memory. Another significant improvement is the addition of native support for compressed textures in WebGL, which is a boost for high-res 3D gaming. Here are release notes for the desktop and mobile versions.

The Obama Administration announced today it has finalized new fuel efficiency standards that will require new cars and light-duty trucks to have an average efficiency of 54.5 miles per gallon by 2025. This adds to the requirement that 2016's new cars must average 35.5 miles per gallon. "The final standards were developed by DOT’s National Highway Traffic Safety Administration (NHTSA) and EPA following extensive engagement with automakers, the United Auto Workers, consumer groups, environmental and energy experts, states, and the public. Last year, 13 major automakers, which together account for more than 90 percent of all vehicles sold in the United States, announced their support for the new standards." According to the administration, the standards will reduce dependence on foreign oil, save money at the pump, protect the environment, and everything else that sounds good in an election year.

After watching this video, a lot of you are going to wish you were Dave Carter, who works at the University of Michigan's Computer and Video Game Archive. He deals with video games, from the oldest hand-helds and consoles to the newest Xbox and PC games and controllers. A lot of his time is no doubt spent fixing things that break, finding obscure games, being generally helpful, and making sure nobody breaks the games, consoles, computers, controllers, and even board games and memorabilia in the collection. But still, this has got to be the ultimate job for a game junkie. And it looks like a great place to visit, because this museum is part of a library, and just as a library encourages you to pick up books and read them, this is a place where you can actually play the games, not just stare at a ColecoVision console in a display case. You can play in a cubicle or, for games that take some space, there are a couple of big gaming rooms with soft-looking sofas and big flat-screen TVs, where you can jump up and down like crazy while you're doing Guitar Hero or using a Wii or Kinect. And if you can't make it to Ann Arbor, MI, there's an informative blog that's all about video games past and present that's must reading for almost any serious gamer.

timeOday writes "BigThink has released a video missive by Bill Nye ('The Science Guy') in which he challenges the low level of acceptance of evolution, particularly in the United States. He does not mince words: 'I say to the grownups, if you want to deny evolution and live in your world, in your world that's completely inconsistent with everything we observe in the universe, that's fine, but don't make your kids do it because we need them. We need scientifically literate voters and taxpayers for the future. We need people that can — we need engineers that can build stuff, solve problems.'"

wiredmikey writes "It's been over a month since spam-spewing Grum botnet has been shut down, but spam experts say there hasn't been a noticeable impact on global spam volume. Symantec researchers at the time estimated that Grum was responsible for one-third of all spam being sent worldwide, and its takedown led to an immediate drop in global spam email volumes by as much as 15 to 20 percent. However, the drop was only temporary. While Grum had an estimated hundred thousand zombies sending spam, the machines were likely blocked for sending emails too frequently, or wound up on IP blacklists, said Andrew Conway, Cloudmark researcher. IP filtering is fast and cheap, and is a good first line of defense against spam, Conway said. Grum spam was easy to blacklist, and despite its size, most spam messages from the botnet probably never reached user inboxes."
