Britain Shuts Off 750,000 Streetlights With No Impact On Crime Or Crashes 71 71

Flash Modin writes: English cities are hard up for cash as the national government dolls out cuts. And in response, the country's councils — local governing bodies — have slashed costs by turning off an estimated 750,000 streetlights. Fans of the night sky and reduced energy usage are happy, but the move has also sparked a national debate. The Automobile Association claims six people have died as a direct result of dimming the lights. But a new study released Wednesday looked at 14 years of data from 63 local authorities across England and Wales and found that residents' chances of being attacked, robbed, or struck by a car were no worse on the darker streets.

On Linux, $550 Radeon R9 Fury Competes With $200~350 NVIDIA GPUs 31 31

An anonymous reader writes: Earlier this month AMD released the air-cooled Radeon R9 Fury graphics card with Fury X-like performance, but the big caveat is the bold performance is only to be found on Windows. Testing the R9 Fury X on Linux revealed the Catalyst driver delivers devastatingly low performance for this graphics card. With OpenGL Linux games, the R9 Fury performed between the speed of a GeForce GTX 960 and 970, with the GTX 960 retailing for around $200 while the GTX 970 is $350. The only workloads where the AMD R9 Fury performed as expected under Linux was the Unigine Valley tech demo and OpenCL compute tests. There also is not any open-source driver support yet for the AMD R9 Fury.

Windows 10 App For Xbox One Could Render Steam Machines Useless 96 96

SlappingOysters writes: The release of Windows 10 has brought with it the Xbox app -- a portal through which you can stream anything happening on your Xbox One to your Surface or desktop. Finder is reporting that the love will go the other way, too, with a PC app coming to the Xbox One allowing you to stream your desktop to your console. But where does this leave the coming Steam Machines? This analysis shows how such an app could undermine the Steam Machines' market position.

Sharp Announces Sales of DC Powered Air Conditioner, Other Products To Follow 152 152

AmiMoJo writes: Sharp has announced that sales of DC powered air conditioners will begin by the end of the year. Most appliances use the standard AC electricity supply in homes, but as solar panels become more common switching to DC can save on conversion losses. Solar panels produce DC, which is then typically converted to AC before being fed into the house's wiring, and then converted back to DC again by appliances. Sharp has announced that it intends to produce a range of DC powered appliances for home use.

Beyond Safety: Is Robotic Surgery Sustainable? 51 51

Hallie Siegel writes: The release last week of the study on adverse events in robotic surgery led to much discussion on the safety and effectiveness of robotic surgical procedures. MIT Sloane's Matt Beane argues that while the hope is that this dialogue will mean safer and more effective robotic procedures in the future, the intense focus on safety and effectiveness has compromised training opportunities for new robotic surgeons, who require many hours of 'live' surgical practice time to develop their skills. Beane says that robotic surgery will likely continue to expand in proportion to other methods, given that it allows fewer surgeons to perform surgery with less trauma to the patient, but no matter how safe we make robotic surgical procedures, they will become a luxury available to a very few if we fail to address the sustainability of the practice.

Nokia Announces OZO 360-Degree Camera For Filming Virtual Reality 21 21

New submitter Sepa Blackforesta writes: Nokia has unveiled Ozo, a next-generation camera for capturing audio and video in 360 degrees. It is built for professional content creators and the company hopes the camera will become the leading device for shooting virtual-reality experiences for Hollywood. A formal launch and price announcement is planned for the fall. A Nokia press release reads in part: "OZO captures stereoscopic 3D video through eight (8) synchronized global shutter sensors and spatial audio through eight (8) integrated microphones. Software built for OZO enables real-time 3D viewing, with an innovative playback solution that removes the need to pre-assemble a panoramic image - a time-consuming process with solutions currently in the marketplace. OZO's filmed content can be published for commercially available VR viewing hardware such as head mounted displays (HMDs), with immersive, full 360-degree imaging and spatially accurate original sound. OZO also integrates into existing professional workflows and works with third-party tools, dramatically simplifying content production at all stages."

Replacing Silicon With Gallium Nitride In Chips Could Reduce Energy Use By 20% 88 88

Mickeycaskill writes: Cambridge Electronics Inc (CEI), formed of researchers from the Massachusetts Institute of Technology (MIT), claim semiconductors made of gallium nitride (GaN) could reduce the power consumption of data centers and consumer electronics by 20 percent by 2025. CEI has revealed a range of GaN transistors and power electronic circuits that have just one tenth of the resistance of silicon, resulting in much higher energy efficiency. The company claims to have overcome previous barriers to adoption such as safety concerns and expense through new manufacturing techniques. "Basically, we are fabricating our advanced GaN transistors and circuits in conventional silicon foundries, at the cost of silicon. The cost is the same, but the performance of the new devices is 100 times better," Cambridge Electronics researcher Bin Lu said.

Ask Slashdot: Why Is the Caps Lock Key Still So Prominent On Keyboards? 612 612

Esther Schindler writes: The developers at .io are into tracking things, I guess. In any case, a few weeks back they decided to track team performance in terms of keyboard and mouse activity during the working day. They installed a simple Chrome plugin on every Macbook and collected some statistics. For instance, developers have fewer keypresses than editors and managers—around 4k every day. Managers type more than 23k characters per day. And so on. Some pretty neat statistics.

But the piece that jumped out at me was this: "What's curious—the least popular keys are Capslock and Right Mouse Button. Somewhere around 0.1% of all keypresses together. It's time to make some changes to keyboards." I've been whining about this for years. Why is it that the least-used key on my keyboard is not just in a prominent position, but also bigger than most other keys? I can I invest in a real alternate keyboard with a different layout (my husband's a big fan of the Kinesis keyboards, initially to cope with carpal tunnel). But surely it's time to re-visit the standard key layout? What keys would you eliminate or re-arrange?

Hacking a 'Smart' Sniper Rifle 64 64

An anonymous reader writes: It was inevitable: as soon as we heard about computer-aimed rifles, we knew somebody would find a way to compromise their security. At the upcoming Black Hat security conference, researchers Runa Sandvik and Michael Auger will present their techniques for doing just that. "Their tricks can change variables in the scope's calculations that make the rifle inexplicably miss its target, permanently disable the scope's computer, or even prevent the gun from firing." In one demonstration they were able to tweak the rifle's ballistic calculations by making it think a piece of ammunition weighed 72 lbs instead of 0.4 ounces. After changing this value, the gun tried to automatically adjust for the weight, and shot significantly to the left. Fortunately, they couldn't find a way to make the gun fire without physically pulling the trigger.

Intel and Micron Unveil 3D XPoint Memory, 1000x Speed and Endurance Over Flash 162 162

MojoKid writes: Today at a press conference in San Francisco, Intel and Micron unveiled 3D XPoint (Cross Point) memory technology, a non-volatile memory architecture they claim could change the landscape of consumer electronics and computer architectures for years to come. Intel and Micron say 3D XPoint memory is 1000 times faster than NAND, boasts 1000x the endurance of NAND, and offers 8-10 times the density of conventional memory. 3D XPoint isn't electron based, it's material based. The companies aren't diving into specifics yet surrounding the materials used in 3D XPoint, but the physics are fundamentally different than what we're used to. It's 3D stackable and its cross point connect structure allows for dense packing and individual access at the cell level from the top or bottom of a memory array. Better still, Intel alluded to 3D XPoint not being as cost-prohibitive as you might expect. Intel's Rob Crooke explained, "You could put the cost somewhere between NAND and DRAM." Products with the new memory are expected to arrive in 2016 and the joint venture is in production with wafers now.

OnePlus Announces OnePlus 2 'Flagship Killer' Android Phone With OxygenOS 148 148

MojoKid writes: The OnePlus 2 was officially unveiled [Monday] evening and it has been announced that the smartphone will start at an competitively low $329, unlocked and contract free. The entry level price nets you a 5.5" 1080p display, a cooler-running 1.8GHz Qualcomm Snapdragon 810 v2.1 SoC paired with 3GB of RAM, 16GB of internal storage, a 13MP rear camera (with OIS, laser focusing and two-tone flash), 5MP selfie camera, and dual nano SIM slots. If you don't mind handing over an extra $60, you'll receive 4GB of RAM to back the processor and 64GB of internal storage. Besides beefing up the internal specs, OnePlus has also paid some attention to the exterior of the device, giving it a nice aluminum frame and a textured backplate. There are a number of optional materials that you can choose from including wood and Kevlar. Reader dkatana links to InformationWeek's coverage, which puts a bit more emphasis on what the phone doesn't come with: NFC. Apparently, people just don't use it as much as anticipated.

Project IceStorm Passes Another Milestone: Building a CPU 104 104

beckman101 writes: FPGAs — specialized, high speed chips with large arrays of configurable logic — are usually highly proprietary. Anyone who has used one is familiar with the buggy and node-locked accompanying tools that FPGA manufacturers provide. Project IceStorm aims to change that by reverse-engineering some Lattice FPGAs to produce an open-source toolchain, and today it passed a milestone. The J1 open-source CPU is building under IceStorm, and running on real hardware. The result is a fairly puny microcontroller, but possibly the world's most open one.
