Linux Kernel Patch Hints At At 32-Core Support For AMD Zen Chips 29

New submitter Iamthecheese points to an article which says that a patch published on the Linux Kernel Mailing List indicates that AMD's forthcoming Zen processors will have as many as 32 cores per socket, but notes that while the article's headline says "Confirms," "the article text doesn't bear that out." Still, he writes, There are hints of such from last year. A leaked patch for the 14 nanometer AMD Zeppelin (Family 17h, Model 00h) reveals support for up to 32 cores. Another blog says pretty much the same thing. We recently discussed an announced 4+8 core AMD chip, but nothing like this.

Report: Google Will Go In Big For VR Hardware This Year 43

The Financial Times reports that Google isn't going to let the VR hardware wars fall to the likes of Samsung and Oculus; instead, it's working on a (cardboard-free) VR headset of its own, to be released in conjunction with Android VR software intended not only to make Android more VR friendly in general but specifically to help developers reduce nausea-inducing lag. The report doesn't quite come out of the blue, considering that Google has shipped more than 5 million of its own Cardboard viewer already, and has several projects dealing with VR infrastructure, either directly (like Jump) or indrectly (like Project Tango). Google (or Alphabet) has proven itself a hardware behemoth, not just the "search giant" it's so often called in news stories, and of late seems to be more interested in making its footprint in hardware a bit firmer.

Ask Slashdot: Surge Protection For International Travel? 113

New submitter gaiageek writes: As someone who has lost a laptop power supply (and thus use of the laptop) due to a late-night power surge while traveling in a developing country, I'm acutely aware of the need for surge protection when traveling abroad. While practically all laptop and phone power adapters these days are voltage auto-sensing 100V-240V compatible, most so-called "travel" surge protectors are restricted to either 110V or 220V. Given the space and weight constraints of carry-on only travel, I'd like to avoid having to carry two separate surge protectors knowing I may go from Central America (110V) to Southeast Asia (220V). Strangely, laptop specific surge protectors typically are 100V-240V compatible, but this doesn't provide protection for a phone or tablet that requires the original power supply (can't be charged from a notebook USB port).

Is there really no solution out there short using a 110V-240V notebook surge protector with an adapter to go from a "cloverleaf" notebook plug to a 5-15R (standard US) plug receptacle?

Unreal Engine Will Soon Allow Developers To Build Games Inside of VR (roadtovr.com) 34

An anonymous reader writes: Epic Games, the creators of Unreal Engine, has been a longstanding supporter of VR. They were on board way back when Oculus sparked the VR industry in 2012 with a Kickstarter that would snowball into a rekindling of consumer virtual reality. Having been one of the first major game engines to support VR headsets like the Rift, the company has been aggressively positioning Unreal Engine as the go-to tool for VR developers. Now they're taking a massive next step, showing the first look at bringing developers themselves inside of virtual reality to craft games with the full set of UE4 tools at their fingertips. That means that developers can place and manipulate objects from right within a world in progress; the video demo in the linked story is impressive.

Let Your Pupils Do the Typing 48

New submitter s.mathot writes: Researchers from France and the Netherlands have developed a way to—literally—write text by thinking of letters. (Academic paper [open access], non-technical blog, YouTube video.) This technique relies on small changes in pupil size that occur when you covertly (from the corner of your eye; without moving your eyes or body) attend to bright or dark objects. By presenting a virtual keyboard on which the 'keys' alternate in brightness, and simultaneously measuring the size of the eye's pupil, the technique automatically determines which letter you want to write; as a result, you can write letters by merely attending to them, without moving any part of your body, including the eyes.

Some Reversible USB-C Cables/Adapters Could Cause Irreversible Damage 132

TheRealHocusLocus writes: Three Decembers ago I lauded the impending death of the trapezoid. Celebration of the rectangle might be premature however, because in the rush-to-market an appalling number of chargers, cables and legacy adapters have been discovered to be non-compliant. There have been performance issues with bad USB implementation all along, but now — with improved conductors USB-C offers to negotiate up to 3A in addition the 900ma base, so use of a non-compliant adapter may result in damage. Google engineer and hero Benson Leung has been waging a one-man compliance campaign of Amazon reviews to warn of dodgy devices and praise the good. Reddit user bmcclure937 offers a spreadsheet summary of the reviews. It's a jungle out there, don't get fried.

Intel Says Chips To Become Slower But More Energy Efficient (thestack.com) 306

An anonymous reader writes: William Holt, Executive Vice President and General Manager of Intel's Technology and Manufacturing Group, has said at a conference that chips will become slower after industry re-tools for new technologies such as spintronics and tunneling transistors. "The best pure technology improvements we can make will bring improvements in power consumption but will reduce speed." If true, it's not just the end of Moore's Law, but a rolling back of the progress it made over the last fifty years.

Amazon's Thin Helvetica Syndrome: Font Anorexia vs. Kindle Readability (teleread.com) 147

David Rothman writes: The Thin Helvetica Syndrome arises from the latest Kindle upgrade and has made e-books less readable for some. In the past, e-book-lovers who needed more perceived-contrast between text and background could find at least partial relief in Helvetica because the font was heavy by Kindle standards. But now some users complain that the 5.7.2 upgrade actually made Helvetica thinner. Of course, the real cure would be an all-text bold option for people who need it, or even a way to adjust font weight, a feature of Kobo devices. But Amazon stubbornly keeps ignoring user pleas even though the cost of adding either feature would be minimal. Isn't this supposed to be a customer-centric company?

Have Your iPhone 6 Repaired, Only To Get It Bricked By Apple (theguardian.com) 395

New submitter Nemosoft Unv. writes: In case you had a problem with the fingerprint sensor or some other small defect on your iPhone 6 and had it repaired by a non-official (read: cheaper) shop, you may be in for a nasty surprise: error 53. What happens is that during an OS update or re-install the software checks the internal hardware and if it detects a non-Apple component, it will display an error 53 and brick your phone. Any photos or other data held on the handset is lost – and irretrievable. Thousands of people have flocked to forums to express their dismay at this. What's more insiduous is that the error may only appear weeks or months after the repair. Incredibly, Apple says this cannot be fixed by any hard- or software update, while it is clearly their software that causes the problem in the first place. And then you thought FTDI was being nasty ...

MIT Reveals "Hack-Proof" RFID Chip (thestack.com) 52

JustAnotherOldGuy writes: A group of researchers at MIT and Texas Instruments claim that they have developed a new radio frequency identification chip that may be impossible to hack. Traditional RFID chips are vulnerable to side-channel attacks, whereby a hacker can extract a cryptographic key from the chip. The new RFID chip runs a random-number generator that creates a new secret key after each transaction. The key can then be verified with a server to ensure that it is correct. The group at MIT also incorporated protection against a power-glitch attack, an attack that would normally leave a chip vulnerable to an interruption of the power source that would in turn halt the creation of a new secret key. Texas Instruments CTO Ahmad Bahai stated, "We believe this research is an important step toward the goal of a robust, lo-cost, low-power authentication protocol for the industrial internet." The question is, how long will it be before this "hack proof" chip is hacked?

Cheap At $40,000: Phoenix Exoskeleton Gives Paraplegics Legs to Walk With 37

Fast Company highlights the cheap-for-the-price Phoenix exoskeleton, created by University of California Berkeley professor (and Berkeley Robotics and Human Engineering Laboratory director) Homayoon Kazerooni and a team of his former grad students at SuitX, a company Kazerooni founded in 2013. Set to sell for $40,000 when it goes on sale next month, the Phoenix sounds expensive -- except compared to the alternatives. For paraplegic patients, there are a handful of other powered exoskeletons, but they cost much more, and are engineered for more than the modest goals of the Phoenix, which allows only one thing: slow walking on level ground. That limited objective means that the rig is light (27 pounds), and relatively unobtrusive. Kazerooni says that he'd like the price to go down much further, too, noting that all the technology in a modern motorcyle can be had for the quarter of the price. A slice: [The] only driving motors in Phoenix are at the hip joints. When the user hits a forward button on their crutches, their left hip swings forward. At this moment, the onboard computer signals the knee to become loose, flex, and clear the ground. As the foot hits, the knee joint stiffens again to support the leg. This computer-choreographed process repeats for the right leg. As it happens, this hinged knee joint has another benefit. If the wearer hits something midstep, like a rock or a curb, a powered knee would blindly drive the leg forward anyway, likely leading to a fall. The hinge naturally absorbs such resistance and allows the wearer a chance to compensate.

Ask Slashdot: Fixing UVC Camera Issues Under Windows? 148

Khyber writes: I bought some cheap Chinese camera glasses with built-in microphones. These are (supposedly) UVC cameras manufactured in 2015. Under Windows XP, these cameras are seen perfectly fine and work as web cameras; even the microphones work. Under Windows 7, the camera appears to install just fine, however I get the 'This device can perform faster if you connect to USB 2.0' (which it is connected to) and when I try to load it up with any camera viewer such as manycam or any chat program's built-in previewer, I cannot receive any video from the camera. I can get audio from the camera microphones under Windows 7, so I am wondering if the camera device is having problems enumerating as a USB 2.0 device due to some change in Windows 7 (which it doesn't seem to have issues doing under XP,) or if the UVC driver for Windows 7 is missing something in comparison to the one used for Windows XP. Anybody else had issues getting newer UVC cameras to work in newer operating systems?

MIT Inches Closer To ARC Reactor Despite Losing Federal Funding (computerworld.com) 181

Lucas123 writes: Experimenting with a fusion device over the past 20 years has edged MIT researchers to their final goal, creating a small and relatively inexpensive ARC reactor, three of which would produce enough energy to power a city the size of Boston. The lessons already learned from MIT's even current Alcator C-Mod fusion device — with a plasma radius of just 0.68 meters — have enabled researchers to publish a paper on a prototype ARC that would be the world's smallest fusion reactor but with the greatest magnetic force and energy output for its size. The ARC would require 50MW to run while putting out about 200MW of electricity to the grid. Key to MIT's ARC reactor would be the use of a "high-temperature" rare-earth barium copper oxide (REBCO) superconducting tape for its magnetic coils, which only need to be cooled to 100 Kelvin, which enables the use of abundant liquid nitrogen as a cooling agent. Other fusion reactors' superconducting coils must be cooled to 4 degrees Kelvin. While there remain hurdles to overcome, such as sustaining the fusion reaction long enough to achieve a net power return, building the ARC would only take 4 to 5 years and cost about $5 billion, compared to the International Thermonuclear Experimental Reactor (ITER), the world's largest tokamak fusion reactor due to go online and begin producing energy in 2027.
