Chess Grandmaster Used iPhone To Cheat During Tournament 237

SternisheFan sends this quote from the Washington Post: Gaioz Nigalidze's rise through the ranks of professional chess began in 2007, the year the first iPhone was released. In hindsight, the timing might not be coincidental. On Saturday, Nigalidze, the 25-year-old reigning Georgian champion, was competing in the 17th annual Dubai Open Chess Tournament when his opponent spotted something strange. "Nigalidze would promptly reply to my moves and then literally run to the toilet," Armenian grandmaster Tigran Petrosian said. "I noticed that he would always visit the same toilet partition, which was strange, since two other partitions weren't occupied." Petrosian complained to the officials. After Nigalidze left the bathroom once more, officials inspected the interior and say they found an iPhone wrapped in toilet paper and hidden behind the toilet. "When confronted, Nigalidze denied he owned the device," according to the tournament's Web site. "But officials opened the smart device and found it was logged into a social networking site under Nigalidze's account. They also found his game being analyzed in one of the chess applications." Nigalidze was expelled from the tournament, which is still ongoing and features more than 70 grandmasters from 43 countries competing for a first-place prize of $12,000. The Georgian's career is now under a microscope. His two national titles are under suspicion.

Sharp Announces 4K Smartphone Display 152

An anonymous reader writes: Japanese electronics giant Sharp has announced production of 5.5" displays with 4K (3840 x 2160) resolution. They'll hit the market next year. The display will have a pixel density of 806 PPI. It's not known yet which smartphone makers will build devices with these screens. The displays cost significantly more than a more typical 1080p or 1440p display, so they'll probably only make it into high-end phones. On the other hand, this will help to drive down prices for lower-resolution displays, so it could indirectly benefit everybody.

The NSA Wants Tech Companies To Give It "Front Door" Access To Encrypted Data 212

Posted by samzenpus
from the let-us-in dept.
An anonymous reader writes The National Security Agency is embroiled in a battle with tech companies over access to encrypted data that would allow it to spy (more easily) on millions of Americans and international citizens. Last month, companies like Google, Microsoft, and Apple urged the Obama administration to put an end to the NSA's bulk collection of metadata. "National Security Agency officials are considering a range of options to ensure their surveillance efforts aren't stymied by the growing use of encryption, particularly in smartphones. Key among the solutions, according to The Washington Post, might be a requirement that technology companies create a digital key that can open any locked device to obtain text messages or other content, but divide the key into pieces so no one group could use it without the cooperation of other parties."

LG's Leather-Clad G4 Revealed In Leaked Images 39

Posted by samzenpus
from the take-a-peek dept.
An anonymous reader writes Evan Blass, known on Twitter as @evleaks, released images of LG's G4 smartphone which was supposed to be unveiled April 28th. "The images reveal what appear to be a multitude of swappable back plates. There are at least six different real leather backs (ranging from black and brown to baby blue and yellow), as well as three more traditional plastic backs. It's fair to assume that the leather versions will carry a cost premium. The LG Quick Circle case, which has a window to let you view notifications while the cover is closed, also appears to be making a return with the G4."

New submitter Analog24 writes: The QWERTY keyboard was not designed with modern touchscreen usage in mind, especially when it comes to swype texting. A recent study attempted to optimize the standard keyboard layout to minimize the number of swype errors. The result was a new layout that reduces the rate of swipe interpretation mistakes by 50.1% compared to the QWERTY keyboard.

Nokia Networks Demonstrates 5G Mobile Speeds Running At 10Gbps Via 73GHz 55

from the that-is-one-packed-headline dept.
Mark.JUK writes The Brooklyn 5G Summit appears to have provided a platform for Nokia Networks to demo a prototype of their future 5G (5th Generation) mobile network technology, which they claim can already deliver data speeds of 10 Gigabits per second using millimeter Wave (mmW) frequency bands of 73GHz. The demo also made use of 2×2 Multiple-Input and Multiple-Output (MIMO) links via single carrier Null Cyclic Prefix modulation and frame size of 100 micro seconds, although crucially no information about the distance of this demo transmission has been released and at 73GHz you'd need quite a dense network in order to overcome the problems of high frequency signal coverage and penetration.

First time accepted submitter Zape (303550) writes The Lollipop update has turned sour for me and several other Nexus 7, Gen 2 (and Nexus 5) owners. It seems that I'm not alone in having my tablet boot to the Google Logo since a couple of days after updating to Android 5.0.2. Now Nexus 5 owners are reporting a reboot loop in Android 5.1. My device, like many others, is a couple of months out of warranty, but worked great until the latest OTA update from Google. They branded it, and they updated it, but Google claims it is between the buyers and ASUS, the manufacturer.

Intel's Core M Performance Is Erratic Between Devices 85

Posted by Soulskill
from the bring-back-the-turbo-button dept.
An anonymous reader writes: AnandTech noticed some odd performance disparities with Intel's Core M CPU, a chip designed to bring high-powered processing to thin, fan-less devices. After investigating, they found that how OEMs build their laptops and tablets has a far greater effect on Core M performance than it does for other chips. "When an OEM designs a device for Core M, or any SoC for that matter, they have to consider construction and industrial design as well as overriding performance. ... This, broadly speaking, gives the OEM control over several components that are out of the hands of the processor designers. Screen size, thickness, industrial design, and skin temperature all have their limits, and adjusting those knobs opens the door to slower or faster Core M units, depending on what the company decides to target.

In the Core M units that we have tested at AnandTech so far this year, we have seen a variety of implementations with and without fans and in a variety of form factors. But the critical point of all of this comes down to how the OEM defines the SoC/skin temperature limitations of the device, and this ends up being why the low-end Core M-5Y10 can beat the high-end Core M-5Y71, and is a poignant part of our tests. Simply put, if the system with 5Y10 has a higher SoC/skin temperature, it can stay in its turbo mode for longer and can end up outperforming a 5Y71, leading to some of the unusual results we've seen so far."

1+ Year Running Arch Linux On a Lenovo Yoga 2 Chronicled 74

from the not-yet-doing-corpse-position dept.
New submitter KeithCu writes with a lengthy explanation of the joys (and just a handful of glitches) he's had in running Arch Linux on his ultraportable, a Lenovo Yoga 2. Other than the hardware-specific issues, I've been amazed by how well Arch Linux works, given that it doesn't have release cycles, or a big team with a lot of money supporting and marketing it. I've heard only 30 developers maintain the core Arch packages, with most of them having a full-time job doing something else! At the same time, it shouldn't be a total surprise things work so well, because free software doesn't just fall off a turnip truck. Not many reviews feature pictures of a laptop charred from building LibreOffice.

Dell Expands Intel RealSense Tablet Lineup With 10.5-Inch Venue 10 7000 2-in-1 22

Posted by samzenpus
from the check-it-out dept.
MojoKid writes "Dell unveiled a new Android 2-in-1 today, the Venue 10 7000, which brings with it many of the same hardware features that we saw with their popular Venue 8 7000 8-inch tablet. It's powered by a quad-core Intel Atom Z3580 processor with 2GB of RAM, 16GB of internal storage, and a 2560x1600 10-inch display. You'll also find a microSD slot that supports up to 512GB of additional storage, 802.11ac, Bluetooth 4.0, Miracast, front-facing stereo speakers, a 2MP front-facing camera, and an 8MP Intel RealSense 3D camera on the rear. Where things get more interesting, perhaps, is with the design of the tablet. Whereas the Venue 8 7000 features a more traditional tablet form-factor, the Venue 10 7000 features a cylindrical "barrel edge" which Dell says makes the tablet easier to hold and carry. It's reminiscent of Lenovo's Android-powered Yoga Tablet family. In addition to providing a handy place for your hand to grip the tablet, the cylindrical spine also serves as an attachment point for an optional keyboard that transforms the Venue 10 7000 into a laptop. The keyboard accessory allows the tablet to be used in five different configurations: Tablet Mode (w/o keyboard), Tablet Mode (w/ keyboard), Laptop Mode, Tablet Stand Mode, and Tent Mode.

from the buying-your-privacy dept.
Toshito writes Desjardins Insurance has launched a smartphone app that tracks driver behaviour in return for the promise of substantial savings on car insurance. Two years ago, Desjardins began offering a telematic device that plugs into a vehicle's diagnostic port, to track acceleration, hard braking and the time of day you were driving, for instance. Now, there's no plug-in device required. With Desjardins's new Ajusto app, all you need is your smartphone. But this comes with great concerns over privacy, and problems have been reported where the device was logging data when the user was riding a bus instead of driving his own car.

Ask Slashdot: How Serious Is Hacking In Mobile Games? 86

Origen writes: As a developer contemplating trying out the mobile game scene, a GDC session about hacking/tampering looked interesting — but I wasn't able to attend. The presentation isn't available online, but it was paired with a whitepaper [contact details required], which can be downloaded. I'm surprised by some of the information presented and the potential for damage/mischief. Not so much that these issues are unheard of — they've existed for years on other platforms. What I find surprising is the lack of support at the OS level on mobile devices to defend from many of these types of hacks. Have we learned nothing from the pains of the past? How significant are the points about hacking/piracy in the mobile space that are discussed by this whitepaper?

Mobile 'Deep Links' and the Fate of the Web 26

Posted by Soulskill
from the URLs-with-short-half-lives dept.
An anonymous reader writes: Mobile developers call the links they're forging between apps "deep links," but so far the whole idea seems to be more about marketing than deepening understanding. This essay over at Backchannel argues that we still haven't delivered on the original promise of links online — the idea of enabling people to build and share "cathedrals of context." Quoting: "The people who invented the link saw it as a tool for relating ideas in illuminating ways—for making conceptual leaps and connecting disparate thoughts. If these visionaries had achieved their aim, the kind of tech-cultural amnesia represented by the recycling of the term 'deep links' shouldn't have been possible, two decades into the Web era. The links with true depth that they envisioned would have made sure of that."

Smartphone-Enabled Replicators Are 3-5 Years Away, Caltech Professor Says 117

merbs writes: In just a few years, we could see the mass proliferation of DIY, smartphone-enabled replicators. At least, Caltech electrical engineering professor Ali Hajimiri and his team of researchers thinks so. They've developed a very tiny, very powerful 3D imager that can easily fit in a mobile device, successfully tested its prowess, and published the high-res results (PDF) in the journal Optics. Hajimiri claims the imager may soon allow consumers to snap a photo of just about anything, and then, with a good enough 3D printer, use it to create a real-life replica "accurate to within microns of the original object."
