AMD FirePro W9100 16GB Workstation GPU Put To the Test 42

Posted by Unknown Lamer from the more-power dept.
Dputiger (561114) writes "It has been almost two years since AMD launched the FirePro W9000 and kicked off a heated battle in the workstation GPU wars with NVIDIA. AMD recently released the powerful FirePro W9100, however, a new card based on the same Hawaii-class GPU as the desktop R9 290X, but aimed at the professional workstation market. The W9100's GPU features 2,816 stream processors, and the card boasts 320GB/s of memory bandwidth, and six mini-DisplayPorts, all of which support DP1.2 and 4K output. The W9100 carries more RAM than any other AMD GPU as well, a whopping 16GB of GDDR5 on a single card. Even NVIDIA's top-end Quadro K6000 tops out at 12GB, which means AMD sits in a class by itself in this area. In terms of performance, this review shows that the FirePro W9100 doesn't always outshine its competition, but its price/performance ratio keep it firmly in the running. But if AMD continues to improve its product mix and overall software support, it should close the gap even more in the pro GPU market in the next 18-24 months."

Scientists Have Developed a Material So Dark That You Can't See It 238

Posted by samzenpus from the none-more-black dept.
gbjbaanb writes A British company is developing a new material that's so black it absorbs all but 0.035 percent of the visual light, making it the darkest material ever created. Of course, apart from making album covers, it conducts heat 7 times better than copper and is 10 times stronger than steel. "The nanotube material, named Vantablack, has been grown on sheets of aluminium foil by the Newhaven-based company. While the sheets may be crumpled into miniature hills and valleys, this landscape disappears on areas covered by it. 'You expect to see the hills and all you can see it's like black, like a hole, like there's nothing there. It just looks so strange,' said Ben Jensen, the firm's chief technical officer.

A Skeptical View of Israel's Iron Dome Rocket Defense System 379

Posted by timothy from the big-badda-boom dept.
Lasrick (2629253) writes It isn't as if real analysis of Israel's "Iron Dome" isn't available, but invariably, whenever Israel has a skirmish the media is filled with glowing reports of how well the system works, and we always find out months later that the numbers were exaggerated. John Mecklin at the Bulletin of the Atomic Scientists looks at the coverage of Iron Dome in the recent exchanges between Israel and Hamas and finds the pattern is repeating itself. However, 'Ted Postol, an MIT-based missile defense expert and frequent Bulletin contributor, provided a dose of context to the Iron Dome coverage in a National Public Radio interview Wednesday. "We can tell, for sure, from video images and even photographs that the Iron Dome system is not working very well at all,"' Includes a good explanation of the differences between Iron Dome (a 'rocket defense system') and missile defense systems pushed by the U.S.

DARPA Successfully Demonstrates Self-Guiding Bullets 188

Posted by Soulskill from the jerks-with-aim-bots dept.
Lucas123 writes: A DARPA-funded project has successfully developed a .50 caliber sniper round capable of maneuvering during flight in order to remain on target. The self-guiding EXACTO bullet, as it's being called, is optically guided by a laser that must remain on target for the bullet to track. The EXACTO round is capable of accurately tracking a target up to 1.2 miles away, DARPA stated. The technology, which is being developed by Teledyne Scientific and Imaging, is targeted at helping snipers remain at longer distances from targets as well as improving night shots. While DARPA's tracking bullet is the first to use a standard, small-arms caliber round, in 2012 Sandia National Laboratories (SNL) successfully demonstrated a prototype self-guided bullet that was more like like a four-inch dart.

Dubai's Climate-Controlled Dome City Is a Dystopia Waiting To Happen 265

Posted by Soulskill from the looking-forward-to-the-reality-tv-show dept.
Daniel_Stuckey writes: Dubai is building "the world's first climate-controlled city" — it's a 4.3 mile pedestrian mall that will be covered with a retractable dome to provide its shoppers with air conditioning in the summer heat. The Mall of the World, as it's called, will become the sort of spectacular, over-the-top attraction Dubai is known for. Shortly after, it will probably become an equally spectacular real-world dystopia.

By sectioning off a 3-million-square-foot portion of the city with an air conditioned dome, Dubai is dropping one of the most tangible partitions between the haves and the have nots of the modern era—the 100 hotels and apartment complexes inside the attraction will be cool, comfortable, and nestled into a entertainment-filled, if macabre, consumer paradise."

Mapping a Monster Volcano 105

Posted by timothy from the shhh-it's-sleeping dept.
bmahersciwriter (2955569) writes In one of the biggest-ever seismology deployments at an active volcano, researchers are peppering Mount St Helens in Washington state with equipment to study the intricate system of chambers and pipes that fed the most devastating eruption in U.S. history. This month, they plan to set off 24 explosions — each equivalent to a magnitude-2 earthquake — around around the slumbering beast in an effort to map the its interior with unprecedented depth and clarity.

Consciousness On-Off Switch Discovered Deep In Brain 284

Posted by samzenpus from the green-light-red-light dept.
An anonymous reader writes "One moment you're conscious, the next you're not. For the first time, researchers have switched off consciousness by electrically stimulating a single brain area. Although only tested in one person, the discovery suggests that a single area – the claustrum – might be integral to combining disparate brain activity into a seamless package of thoughts, sensations and emotions. It takes us a step closer to answering a problem that has confounded scientists and philosophers for millennia – namely how our conscious awareness arises. When the team zapped the area with high frequency electrical impulses, the woman lost consciousness. She stopped reading and stared blankly into space, she didn't respond to auditory or visual commands and her breathing slowed. As soon as the stimulation stopped, she immediately regained consciousness with no memory of the event. The same thing happened every time the area was stimulated during two days of experiments.

Study: People Would Rather Be Shocked Than Be Alone With Their Thoughts 333

Posted by samzenpus from the still-your-mind dept.
sciencehabit writes "How much do we hate being alone with our own thoughts? Enough to give ourselves an electric shock. In a new study, researchers recruited hundreds of people and made them sit in an empty room and just think for about 15 minutes. About half of the volunteers hated the experience. In a separate experiment, 67% of men and 25% of women chose to push a button and shock themselves rather than just sit there quietly and think. One of the study authors suggests that the results may be due to boredom and the trouble that we have controlling our thoughts. "I think [our] mind is built to engage in the world," he says. "So when we don't give it anything to focus on, it's kind of hard to know what to do."

Privacy Oversight Board Gives NSA Surveillance a Pass 170

Posted by Soulskill from the raise-your-hand-if-you're-surprised dept.
An anonymous reader writes There's an independent agency within the U.S. government called the Privacy and Civil Liberties Oversight Board. Their job is to weigh the benefits of government actions — like stopping terrorist threats — against violations of citizens' rights that may result from those actions. As you might expect, the NSA scandal landed squarely in their laps, and they've compiled a report evaluating the surveillance methods. As the cynical among you might also expect, the Oversight Board gave the NSA a pass, saying that while their methods were "close to the line of constitutional reasonableness," they were used for good reason. In the completely non-binding 191-page report (PDF), they said, "With regard to the NSA's acquisition of 'about' communications [metadata], the Board concludes that the practice is largely an inevitable byproduct of the government's efforts to comprehensively acquire communications that are sent to or from its targets. Because of the manner in which the NSA conducts upstream collection, and the limits of its current technology, the NSA cannot completely eliminate 'about' communications from its collection without also eliminating a significant portion of the 'to/from' communications that it seeks."

If Immigration Reform Is Dead, So Is Raising the H-1B Cap 341

Posted by Soulskill from the congress-members-shouting-at-one-another dept.
dcblogs writes: In a speech Wednesday on the floor of the U.S. House of Representatives, Rep. Luis Gutierrez (D-Ill.) declared immigration reform dead. He chastised and baited Republicans in Congress for blocking reform, and declared that winning the White House without the support of a growing Hispanic population will become mathematically impossible. "The Republican Presidential nominee, whoever he or she may be, will enter the race with an electoral college deficit they cannot make up," said Gutierrez. If he's right, and comprehensive immigration reform is indeed dead, then so too is the tech industry's effort to raise the cap on H-1B visas. Immigration reform advocates have successfully blocked any effort to take up the immigration issue in piecemeal fashion, lest business support for comprehensive reform peel away. Next year may create an entirely new set of problems for tech. If the Republicans take control of the Senate, the tech industry will face this obstacle: Sen. Chuck Grassley (R-Iowa). Grassley, the ranking Republican on the Judiciary Committee could become its next chairman. He has been a consistent critic of the H-1B program through the years. "The H-1B program is so popular that it's now replacing the U.S. labor force," said Grassley, at one point.

Massachusetts SWAT Teams Claim They're Private Corporations, Immune To Oversight 534

Posted by Soulskill from the you-can-trust-us dept.
New submitter thermowax sends a report on how Massachusetts SWAT teams are dodging open records requests by claiming to be corporations. From the article: As it turns out, a number of SWAT teams in the Bay State are operated by what are called law enforcement councils, or LECs. These LECs are funded by several police agencies in a given geographic area and overseen by an executive board, which is usually made up of police chiefs from member police departments. ... Some of these LECs have also apparently incorporated as 501(c)(3) organizations. And it's here that we run into problems. According to the ACLU, the LECs are claiming that the 501(c)(3) status means that they're private corporations, not government agencies. And therefore, they say they're immune from open records requests. Let's be clear. These agencies oversee police activities. They employ cops who carry guns, wear badges, collect paychecks provided by taxpayers and have the power to detain, arrest, injure and kill. They operate SWAT teams, which conduct raids on private residences. And yet they say that because they've incorporated, they're immune to Massachusetts open records laws. The state's residents aren't permitted to know how often the SWAT teams are used, what they're used for, what sort of training they get or who they're primarily used against.
