In four short years, the Open Compute Project has turned the $141 billion data-center computer-hardware industry on its head. This is the comprehensive history of the project, including interviews with founder Jonathan Heiliger and members of the financial services industry who are already on board, plus a dismissal from Google's own data center guru Urs Holzle.

To monitor a person's sleep, the app transforms the user's smartphone into an active sonar system that tracks tiny changes in a person's movements. The phone's speaker sends out inaudible sound waves, which bounce off a sleeping person's body and are picked back up by the phone's microphone. "It's similar to the way bats navigate," said Rajalakshmi Nandakumar, lead author and a doctoral candidate in the UW's department of computer science and engineering. "They send out sound signals that hit a target, and when those signals bounce back they know something is there." In technical terms, the app continuously analyzes changes in the acoustic room-transfer-function (sampled at ultrasonic frequencies) to detect motion. This is very similar to what the iPhone app Sleep Cycle Sonalarm Clock does, except that the UW researchers have improved the sensitivity of the method so it can precisely track the person's breathing movements which allows it to not only detect different sleep phases but also sleep apnea events. The advantage in both use cases is that the sleep monitoring is contact-less (there's nothing in the user's bed that could disturb their sleep) and doesn't require any additional hardware besides the user's smart phone.

The headset's origins come from InfinitEye, a company working on a super-wide dual-display headset back in 2013, which went into stealth mode for quite some time before being reborn as StarVR in partnership with Starbreeze Studios. The studio is the developer behind the Payday franchise, Brothers: A Tale of Two Sons, and now Overkill's The Walking Dead, which will have a VR component utilizing the new headset.

The G27 has been a popular gaming peripheral (it supports the PC, PlayStation 2 and PlayStation 3) that not only includes a steering wheel and three pedals (accelerator, brake, clutch), but also a six-speed "H" pattern gearbox. Today, Logitech is finally introducing successors, the G29 Driving Force Racing Wheel and the G920 Driving Force Racing Wheel for PS3 and PS4, as well as PC and Xbox One racers, respectively. Both wheels are equipped with dual-motor force feedback, 900-degree (2.5 turns to lock) steering, helical gearing, and anti-backlash hardware. Logitech is also hoping to impart a premium feel to its new controllers courtesy of a hand-stitched leather wheel, stainless steel paddle shifters, and steel ball bearings to stand up to abuse. Like its predecessor, the G29 and G920 both come with a separate, floor-mounted three-pedal unit to keep your feet busy when blasting around the Nürburgring. Unfortunately, the six-speed shifter unit that used to come standard in the box with the G27 is now an optional accessory. The G29 will be available this July, while the G920 won't arrive at retailers until October.

It was capable of capturing an ant without harming it, and the tentacle was also able to grasp the egg of a fish. Such miniature soft robots could be useful for microsurgery. The lassoing motion and low force exerted by the tentacle could be an advantage in endovascular operations, for example, where the target for surgery is reached through blood vessels. They describe their findings in Scientific Reports.

jan_jes writes: Origami is the Japanese art of paper folding created by Akira Yoshizawa, which can be used to create beautiful birds, frogs and other small sculptures. Last year a team of engineers from MIT and Harvard has developed an origami flat-pack robot (YouTube video) which can fold itself and crawl away without any human intervention. But now a Binghamton University engineer says this technique can be applied to building batteries, too. The battery generates power from microbial respiration, delivering enough energy to run a paper-based biosensor with nothing more than a drop of bacteria-containing liquid. This method should be especially useful to anyone working in remote areas with limited resources. The total cost of this potentially game-changing device is "five cents."

Bruce66423 writes: Valves for the new generation of French reactors being built now have raised substantial safety concerns on top of the existing issues about the quality of the steel used for the containment vessel. Similar to the Three Mile Island nuclear accident, France’s nuclear safety watchdog found “multiple” malfunctioning valves in the Flamanville EPR that could cause its meltdown. The Telegraph reports: "The watchdog reportedly cited 'multiple failure modes' that could have 'grave consequences' on the safety relief valves, which play a key role in regulating pressure in the reactor. Owned by state-controlled French utilities giant EDF, Flamanville lies close to the British Channel Islands and about 150 miles from the southern English coast. Designed to be the safest reactors in the world and among the most energy-efficient, the €9 billion (£6.5 billion) EPR has suffered huge delays in models under construction in France, Finland and China. It is now due to enter service in 2017, five years later than originally planned."

MojoKid writes: A fresh alleged leak of next AMD Fiji graphics info has just hit the web and there's an abundance of supposedly confirmed specifications for what will be AMD's most powerful graphics card to date. Fiji will initially be available in both Pro and XT variants with the Fiji Pro dubbed "Fury" and Fiji XT being dubbed "Fury X." The garden variety Fury touts single-precision floating point (SPFP) performance of 7.2 TFLOPS compared to 5.6 TFLOPS for a bone stock Radeon R9 290X. That's a roughly 29-percent performance improvement. The Fury X with its 4096 stream processors, 64 compute units, and 256 texture mapping units manages to deliver 8.6 TFLOPS, or a 54-percent increase over a Radeon R9 290X. The star of the show, however, will be AMD's High Bandwidth Memory (HBM) interface. Unlike traditional GDDR5 memory, HBM is stacked vertically, decreasing the PCB footprint required. It's also integrated directly into the same package as the GPU/SoC, leading to further efficiencies, reduced latency and a blistering 100GB/sec of bandwidth per stack (4 stacks per card). On average HBM is said to deliver three times the performance-per-watt of GDDR5 memory. With that being said, the specs listed are by no means confirmed by AMD, yet. We shall find out soon enough during AMD's E3 press conference scheduled for June 16.

According to the New York Times, Microsoft has chosen to manufacture its Surface Hub in Wilsonville, Oregon. The announcement follows Apple's decision to build the Mac Pro in Texas. "It makes a lot of sense to manufacture in the U.S.," said Steve Hix, an entrepreneur who founded several Portland-area tech companies, including one that had a manufacturing facility in Wilsonville. "The key issue is quality."

Context would be interesting, too — if you're up for it, explain how and why you set it up as you did, as well as the computer's primary purpose(s). Things you can list include (but are not limited to): CPU, motherboard, video card, memory, storage (SSD/HDD), exotic Controllers (RAID or caching), optical drives, displays, peripherals, etc. We can compare and contrast, see what specs are suitable for what purposes, and perhaps learn a trick or two.

An anonymous reader writes: Last week saw the release of an open letter written to President Obama by a committee of notable political, security and defense experts — which includes past and present members of Congress, ambassadors, CIA directors, and others — on the country's concerning level of vulnerability to a natural or man-made Electro-Magnetic Pulse (EMP). An EMP has very real potential for crippling much of our electrical grid instantaneously. Not only would that immediately throw the social order into chaos, but the timeline to repair and restart the grid in most estimated scenarios would take months to a year or more.

Executive Director of the EMP Task Force Dr Peter Pry said, "Well, the short answer to [why we aren't defending against EMPs] is called the North American Electric Reliability Corporation. They used to be a trade association or a lobby for the 3,000 electric utilities that exist in this country. ... There is no part of the U.S. government that has the legal powers to order them to protect the grid. This is unusual, because in the case of every other critical infrastructure, there's an agency in the U.S. government that can require them to take actions for public safety. For example, the Food & Drug Administration can order certain medicines kept off shelves to protect the public safety. ... The U.S. Federal Energy Regulatory Commission doesn't have those legal powers or authorities."

stowie writes: The DARPA Robots Challenge concluded recently, and three teams were given prizes for completing all the tasks. The other robots in the competition struggled — not only were they unable to complete the required tasks, many of them were unable to even stay standing the entire time. So why did these robots have such a hard time? "DARPA deliberately degraded communications (low bandwidth, high latency, intermittent connection) during the challenge to truly see how a human-robot team could collaborate in a Fukushima-type disaster. And there was no standard set for how a human-robot interface would work. So, some worked better than others. The winning DRC-Hubo robot used custom software designed by Team KAIST that was engineered to perform in an environment with low bandwidth. It also used the Xenomai real-time operating system for Linux and a customized motion control framework. The second-place finisher, Team IHMC, used a sliding scale of autonomy that allowed a human operator to take control when the robot seemed stumped or if the robot knew it would run into problems." If nothing else, the competition's true legacy may lie in educating the public on the realistic capabilities of high-tech robots.

Okian Warrior notes a Stanford project to build a basic computer that operates on water droplets. One of its creators, Manu Prakash, says the goal is not to compete with digital computers for manipulating data (though they can theoretically perform all of the same computations). Instead, "Our goal is to build a completely new class of computers that can precisely control and manipulate physical matter. Imagine if when you run a set of computations that not only information is processed but physical matter is algorithmically manipulated as well." The biggest obstacle in creating the water computer was figuring out a way to develop a clock mechanism. The team decided to use a rotating magnetic field, which is both precise and easy to control. To get it to interact with the water, they put arrays of tiny iron bars on glass slides, and then added a layer of oil, and finally another glass slide. Magnetized water droplets are injected into this scaffolding, and the magnetic field can then easily push them along paths created by the iron. "It's about manipulating matter faster," Prakash said.

A few days ago, what might be the first 8K video entitled "Ghost Towns" was published on Youtube and you can now watch it for yourself in its full 7680 × 4320 pixel glory — that is if you happen to have access to a 8K display (or projector).

The video was created by cinematographer Luke Neumann who used a 6K EPIC DRAGON camera using some advanced and complex techniques such as shooting in portrait orientation and then stitched the video together in Adobe After Effects. Some shots simply scaled up by 125% from 6.1K to meet the 7.6K standard and handheld stuff was 6K scaled up by 125% and sharpened up.

Youtube is now offering an 8K option and according to Google: "8K video has been supported since 2010, but that labeling for 8K video (the 4320p/8K quality setting like pictured above) was added "earlier this year — but presumably there was noting to view — until now...

"Angela Merkel took the G7 by the scruff of the neck," said Ruth Davis a political advisor to Greenpeace and a senior associate at E3G. "Politically, the most important shift is that chancellor Merkel is back on climate change. This was not an easy negotiation. She did not have to put climate change on the agenda here. But she did," Davis said. The G7 plege includes a goal proposed by the EU to cut emissions 60% on 2010 levels by 2050, with full decarbonisation by 2100.

An anonymous reader writes: In trying to offer a unique look at how Intel x86 CPU performance has evolved since their start, Phoronix celebrated their 11th birthday by comparing modern CPUs to old Socket 478 CPUs with the NetBurst Celeron and Pentium 4C on an Intel 875P+ICH5R motherboard. These old NetBurst processors were compared to modern Core and Atom processors from Haswell, Broadwell, Bay Trail and other generations. There were also some AMD CPUs and the NVIDIA Tegra K1 ARM processor. Surprisingly, in a few Linux tests the NetBurst CPUs performed better than AMD E-Series APUs and an Atom Bay Trail. However, for most workloads, the 45+ other CPUs tested ended up being multiple times faster; for the systems where the power consumption was monitored, the power efficiency was obviously multiple times better.
