Linux 3.18 Released, Lockup Bug Still Present

jones_supa writes As anticipated, Linus Torvalds officially released Linux 3.18. The new version is now out there, though that nasty lockup issue has still yet to be resolved. Dave Jones is nearing the end of bisecting the issue, but since it also affects Linux 3.17 and not too many people seem to get hit by the lockups, Linus Torvalds decided to go ahead and do the 3.18 release on schedule. Linus was also concerned that dragging out the 3.18 release would then complicate the Linux 3.19 merge window due to the holidays later this month. Now the Linux 3.19 kernel merge window is open for two weeks of exciting changes. Read more of this story at Slashdot.

The Fastest Camera Ever Made Captures 100 Billion Frames Per Second

Jason Koebler writes A new imaging technique is able to capture images at 100 billion frames per second—fast enough to watch light interact with objects, which could eventually lead to new cloaking technologies. The camera was developed by a team at Washington University in St. Louis—for the team’s first tests, it was able to visualize laser pulse reflections, photons racing through air and through resin, and “faster-than-light propagation of non-information.” It can also be used in conjunction with telescopes and to image optical and quantum communications, according to lead researcher Liang Gao.

How High-Tech Temporary Tattoos Will Hack Your Skin

Molly McHugh writes with this story about sensors that can be attached to temporary tattoos to monitor various medical information. “The Center for Wearable Sensors at the University of California San Diego has been experimenting with attaching sensors to temporary tattoos in order to extract data from the body. The tattoos are worn exactly as a regular temporary tattoo would be worn. The sensors simply sit atop the skin without penetrating it and interact with Bluetooth or other wireless devices with a signal in order to send the data….A biofuel battery applied as a temporary tattoo converts sweat into energy, and a startup within the center has developed a strip that extracts data from sweat to explain how your body is reacting to certain types of exercise. Amay Bandodkar, a fourth year PhD student at UCSD, explains that the sensors are programmed to react to the amount of lactate the body produces.” Read more of this story at Slashdot.

Windows 10 Adds Battery Saver Feature

jones_supa writes In past builds of Windows 10 Technical Preview there has been an interesting feature called Battery Saver, but for the time being it has been just a mockup. In a leaked build 9888, the code is now in place. Battery Saver, as the name implies, will help your mobile device make the most out of your battery. This feature works by limiting the background activity on your device when the mode is activated. You can turn the feature on any time but there is also a setting to have it automatically turn on when the battery capacity goes below a user-defined percentage. Considering that this build was not supposed to make its way out of Redmond and that the company is not releasing any new builds this year, this may be the best look we get until the Consumer Preview arrives.

Consumer-Grade SSDs Survive Two Petabytes of Writes

crookedvulture writes The SSD Endurance Experiment previously covered on Slashdot has reached another big milestone: two freaking petabytes of writes. That’s an astounding total for consumer-grade drives rated to survive no more than a few hundred terabytes. Only two of the initial six subjects made it to 2PB. The Kingston HyperX 3K, Intel 335 Series, and Samsung 840 Series expired on the road to 1PB, while the Corsair Neutron GTX faltered at 1.2PB. The Samsung 840 Pro continues despite logging thousands of reallocated sectors. It has remained completely error-free throughout the experiment, unlike a second HyperX, which has suffered a couple of uncorrectable errors. The second HyperX is mostly intact otherwise, though its built-in compression tech has reduced the 2PB of host writes to just 1.4PB of flash writes. Even accounting for compression, the flash in the second HyperX has proven to be far more robust than in the first. That difference highlights the impact normal manufacturing variances can have on flash wear. It also illustrates why the experiment’s sample size is too small to draw definitive conclusions about the durability of specific models. However, the fact that all the drives far exceeded their endurance specifications bodes well for the endurance of consumer-grade SSDs in general. Read more of this story at Slashdot.

IoT Is the Third Big Technology ‘Wave’ In the Last 50 Years, Says Harvard

dcblogs writes: The Internet of Things (IoT) may be more significant in reshaping the competitive landscape than the arrival of the Internet. Its productivity potential is so powerful it will deliver a new era of prosperity. That’s the argument put forth by Michael Porter, an economist at the Harvard Business School and James Heppelmann, president and CEO of PTC, in a recent Harvard Business Review essay. PTC is a product design software firm that recently acquired machine-to-machine firm Axeda Corp. In the past 50 years, IT has delivered two major transformations or “waves, ” as the authors describe it. The first came in the 1960s and 1970s, with IT-enabled process automation, computer-aided design and manufacturing resource planning. The second was the Internet and everything it delivered. The third is IoT. That’s a strikingly sweeping claim and there will no doubt be contrarians to Porter and Heppelmann’s view. But what analysts are clear about is that IoT development today is at an early stage, perhaps at a point similar to 1995, the same year Amazon and eBay went online, followed by Netflix in 1997 and Google in 1998. People understood the trend at the time, but the big picture was still out of focus. Read more of this story at Slashdot.

How the Rollout of 5G Will Change Everything

mrspoonsi writes The global race is on to develop 5G, the fifth generation of mobile network. While 5G will follow in the footsteps of 4G and 3G, this time scientists are more excited. They say 5G will be different — very different. “5G will be a dramatic overhaul and harmonization of the radio spectrum, ” says Prof Rahim Tafazolli who is the lead at the UK’s multimillion-pound government-funded 5G Innovation Centre at the University of Surrey. To pave the way for 5G the ITU is comprehensively restructuring the parts of the radio network used to transmit data, while allowing pre-existing communications, including 4G and 3G, to continue functioning. 5G will also run faster, a lot faster. Prof Tafazolli now believes it is possible to run a wireless data connection at an astounding 800Gbps — that’s 100 times faster than current 5G testing. A speed of 800Gbps would equate to downloading 33 HD films — in a single second. Samsung hopes to launch a temporary trial 5G network in time for 2018’s Winter Olympic Games.

Conglomerate Rock From Mars: (Much) More Precious Than Gold

An anonymous reader writes It’s the oldest rock on Earth–and it’s from Mars. A 4.4-billion-year-old martian meteorite, found in a dozen pieces in the western Sahara, has ignited a frenzy among collectors and scientists; prices have reached $10, 000 a gram, and museums and universities are vying for slivers of it. It is the only known martian meteorite made of sediment, a conglomerate of pebbles and other clumps of minerals from when the planet was warm, wet, and possibly habitable. The story of the discovery of the rock and its significance is fascinating, as well as the details presented about the economics of rare space materials. Apropos, this older story about missing moon rocks. Read more of this story at Slashdot.

Bidding In Government Auction of Airwaves Reaches $34 Billion

An anonymous reader sends word that the 2014 wireless spectrum license auction has surpassed $34 billion. “A government auction of airwaves for use in mobile broadband has blown through presale estimates, becoming the biggest auction in the Federal Communications Commission’s history and signaling that wireless companies expect demand for Internet access by smartphones to continue to soar. And it’s not over yet. Companies bid more than $34 billion as of Friday afternoon for six blocks of airwaves, totaling 65 megahertz of the electromagnetic spectrum, being sold by the F.C.C. That total is more than three times the $10.5 billion reserve price that the commission put on the sale, the first offering of previously unavailable airwaves in six years.” Read more of this story at Slashdot.
