jfruh writes "Some melancholy news from the Hot Chips symposium last week: NAND memory, which powers the solid-state drives that have revolutionized storage, has broken the $1 per gigabyte barrier and isn't getting any cheaper. 'They will always be ten times the cost of a hard drive,' says analyst Jim Handy. There are newer technologies in development, but they won't be able to beat NAND on price for years."
DoctorBit writes "A team of researchers funded in part by the NSF has just published a paper in which they demonstrate a way to introduce hardware Trojans into a chip by altering only the dopant masks of a few of the chip's transistors. From the paper: 'Instead of adding additional circuitry to the target design, we insert our hardware Trojans by changing the dopant polarity of existing transistors. Since the modified circuit appears legitimate on all wiring layers (including all metal and polysilicon), our family of Trojans is resistant to most detection techniques, including fine-grain optical inspection and checking against "golden chips."' In a test of their technique against Intel's Ivy Bridge Random Number Generator (RNG) the researchers found that by setting selected flip-flop outputs to zero or one, 'Our Trojan is capable of reducing the security of the produced random number from 128 bits to n bits, where n can be chosen.' They conclude that 'Since the Trojan RNG has an entropy of n bits and [the original circuitry] uses a very good digital post-processing, namely AES, the Trojan easily passes the NIST random number test suite if n is chosen sufficiently high by the attacker. We tested the Trojan for n = 32 with the NIST random number test suite and it passed for all tests. The higher the value n that the attacker chooses, the harder it will be for an evaluator to detect that the random numbers have been compromised.'"
Lucas123 writes "On the news that Linus Torvalds's SSD went belly up while he was coding the 3.12 kernel, Computerworld took a closer look at SSDs and their failure rates. While Torvalds didn't specify the SSD manufacturer in his blog, he did write in a 2008 blog that he'd purchased an 80GB Intel SSD — likely the X25, which has become something of an industry standard for SSD reliability. While they may have no mechanical parts, making them preferable for mobile use, there are many factors that go into an SSD being reliable. For example, a NAND die, the SSD controller, capacitors, or other passive components can — and do — slowly wear out or fail entirely. As an investigation into SSD reliability performed by Tom's Hardware noted: 'We know that SSDs still fail.... All it takes is 10 minutes of flipping through customer reviews on Newegg's listings.' Yet, according to IHS, client SSD annual failure rates under warranty tend to be around 1.5%, while HDDs are near 5%. So SSDs not only outperform, but on average outlast spinning disks."
MojoKid writes "News from Intel (and Google) today includes an announcement that more Chromebooks are on their way to market packing Intel's Haswell processors. The new chips are designed to consume less power, thus preserving battery life for an all-day charge, while still offering better overall performance. Google notes that there are schools in over 20% of school districts across the country that now use Chromebooks, and with prices for some of the machines dipping as low as $199, deploying fleets of these machines in academia is an attractive option. What's interesting is the alignment between Intel and Google now, which should cause folks in Redmond to smart a bit, as yet another major competitor to the Windows operating system seems to clearly be coming into focus. Intel-Google partners including Acer, ASUS, HP, and Toshiba will be rolling out Chromebooks based on Haswell soon, and they'll collectively be sporting more variety of form factors."
awarrenfells writes "After a shareholder vote, Michael Dell is expected to buy out and take Dell Inc. private. This move comes in the wake of plans to move Dell into position as an enterprise computing provider, but some analysts state this move may have come too late, much of the target market being taken by IBM and HP already." Nerval's Lobster provides some more details at Slash Cloud: "[T]he final buyout price was $13.75 a share, which includes a 13-cent-a-share “special dividend.” All told, that puts the deal’s price at $24.9 billion. In order to reach this point, Dell and Silver Lake had to fend off activist investor Carl Icahn and investment firm Southeastern Asset Management, which made their own combined play for a restructured capitalization. In a series of public letters, Icahn argued that Dell’s privatization proposal undervalued the company, and—at least until the beginning of September—made it very clear that he was willing to fight things out in court. By convincing the shareholders that his plan is the best route forward, Dell avoids what could have devolved into a very protracted and messy battle. Michael Dell wants to focus the majority of the company’s efforts on services, essentially remaking it into a tech firm more along the lines of IBM."
Nerval's Lobster writes "Apple's iPhone 5S features a fingerprint scanner embedded in the home button. Of course, fingerprint-scanning technology isn't new: Bloomberg Terminals feature a built-in fingerprint reader to authenticate users, for example, and various manufacturers have experimented with laptops and smartphones that require a thumb to login. But the technology has thus far failed to become ubiquitous in the consumer realm, and it remains to be seen whether the new iPhone — which is all but guaranteed to sell millions of units — can popularize something that consumers don't seem to want. Security experts seem to be adopting a wait-and-see attitude with regard to Apple's newest trick. 'I'd caution right away, let's see how it tests and what people come up with to break it,' Brent Kennedy, an analyst with the U.S. Computer Emergency and Readiness Team, told Forbes. 'I wouldn't rely on it solely, just as I wouldn't with any new technology right off the bat.' And over at Wired, technologist Bruce Schneier is suggesting that biometric authentication could be hacked like anything else. 'I'm sure that someone with a good enough copy of your fingerprint and some rudimentary materials engineering capability — or maybe just a good enough printer — can authenticate his way into your iPhone,' he wrote. 'But, honestly, if some bad guy has your iPhone and your fingerprint, you've probably got bigger problems to worry about.'"

The tablet is powered by an Atom Z3740 processor with quad cores clocked at up to 1.8GHz—600MHz slower than the Z3770 chip benchmarked by the press. The screen has a relatively low 1366x768 resolution, but at least the IPS panel delivers wide viewing angles. Asus clearly intends the T100 to be an entry level device; the 32GB version is slated to sell for just $349, and the 64GB one will cost only 50 bucks more. Those prices include the keyboard dock and a copy of Microsoft Office Home & Student 2013. They also bring Windows 8 convertibles down to truly budget territory, completing the collision between tablets and netbooks."
An anonymous reader writes "The New York Times reports, 'For eight decades, Manson Whitlock kept the 20th century's ambient music going: the ffft of the roller, the ding of the bell, the decisive zhoop ... bang of the carriage return, the companionable clack of the keys. From the early 1930s until shortly before his death last month at 96, Mr. Whitlock, at his shop in New Haven, cared for the instruments, acoustic and electric, on which that music was played. Mr. Whitlock was often described as America's oldest typewriter repairman. He was inarguably one of the country's longest-serving. Over time he fixed more than 300,000 machines, tending manuals lovingly, electrics grudgingly and computers never. "I don't even know what a computer is," Mr. Whitlock told The Yale Daily News, the student paper, in 2010. "I've heard about them a lot, but I don't own one, and I don't want one to own me."'"

Vigile writes "Today at the Intel Developer Forum in San Francisco, the company officially released the Atom Z3000 series of SoCs (Bay Trail) based on the Silvermont architecture. Unlike previous Atom designs, the Z3000 and Silvermont is a completely re-architected product from the ground up and is no longer based on legacy processors. Changes include a move to an out-of-order x86 architecture with drastically improved single threaded performance but the removal of Intel's HyperThreading technology. Dual-core modules with 1MB of shared cache can be paired up to create a quad-core SoC that also includes upgraded graphics design. Intel is no longer depending on PowerVR for a GPU and has integrated a 4 EU (execution unit) Intel HD Graphics design that is very similar to the one used in Ivy Bridge. As a result, as tested at PC Perspective in both Windows 8.1 and Android 4.2.2, the Bay Trail part is as much as 4x faster in single threaded tasks and 3.5x faster in gaming and graphics. Power consumption remains nearly the same as it did with Clover Trail (Atom Z2760) but with improved power gating and support for Connected Standby, Intel's new Atom looks and feels completely different than any before it." MojoKid notes that Intel also announced an "open" SoC architecture (where open involves you giving Intel tons of money).

'The wires generated in Bomb Defuse Simulator 2013 are created procedurally to provide the player with a random challenge each time the game is played. ...

SmartAboutThings sends this excerpt from Technology Personalized: "Intel has started shipping the fourth generation Haswell chips for tablets, which brings power-efficient processors and hence much better battery life to Windows tablets. According to IDG, Intel has now started shipping new low-power, fourth-generation Core i3 processors, including one that draws as little as 4.5 watts of power in specific usage scenarios. These new Haswell processors could go into fanless tablets and laptop-tablet hybrids, bringing longer battery life to the devices. This is a great news for Windows lovers, who have had to sacrifice performance for battery life (and vice versa) until now. Now, with almost 50% better battery life as promised by Intel for Windows tablets, the OEMs have no real need to come out with Windows RT based tablets and hybrids anymore."

The technology, still in prototype phase, uses the same spectrum as other wireless standards, such as WiFi and Bluetooth. The Cota wireless charging system includes a charger and a receiver — either a dongle device or chip-tech integrated into a product, such as a smartphone or battery. While it has yet to be miniaturized, Zeine said the wireless technology will eventually be small enough to fit into a AAA battery or any portable electronic device. While the technology has wider industrial implications, as a consumer product, a charging unit will likely sell for around $100, he said."
crookedvulture writes "Seagate has begun shipping hard drives based on a new technology dubbed Shingled Magnetic Recording. SMR, as it's called, preserves the perpendicular bit orientation of current HDDs but changes the way that tracks are organized. Instead of laying out the tracks individually, SMR stacks them on top of each other in a staggered fashion that resembles the shingles on a roof. Although this overlap enables higher bit densities, it comes with a penalty. Rewrites compromise the data on the following track, which must be read and rewritten, which in turn compromises the data on the following track, and so on. SMR distributes the layered tracks in narrow bands to mitigate the performance penalty associated with rewrites. The makeup of those bands will vary based on the drive's intended application. We should see the first examples of SMR next year, when Seagate intends to introduce a 5TB drive with 1.25TB per platter. Traditional hard drives top out at 4TB and 1TB per platter right now."

It did it for smartphones, once, and again, for tablets. The question that Apple has been charged with, since nobody has definitively answered it yet, is whether the lack of an invention that truly carries us beyond the last five hundred years of wrist-mounted technology is the result of a failure of imagination or simply a fact of nature-that a watch will always just be a watch, no matter how smart it might think it is.'

He moved on to manipulating an actual 3D CAD model and interacting with the software; you can see that he used a Leap Motion controller. Next, he shows off a 3D projection, a freestanding glass projection (Ironman style), and interacts with the model using the Oculus Rift. Finally, he prints the part in titanium with a 3D metal printer. Note that we don't actually see him design anything; the models he works with are already made. Still, it's exciting to see new ways of doing things come to life on screen."

colinneagle writes with word of work done by researchers at Arizona State University, Delaware State University and GFS Technology Inc., who find that the multiple-picture sequence security option of Windows 8 suffers from various flaws -- some of them specific to a password system based on gestures, and some analogous to weaknesses in conventional passwords entered by keyboard. "The research found that the strength of picture gesture password has a 'strong connection' to how long a person spent setting up that password gesture. The most common gesture combination is three taps, meaning it took about 4.33 — 5.74 seconds to setup. Passwords with two circles and one line took the longest average input time of about 10.19 seconds. After studying why people choose certain categories of images, the most common gesture types and direction patterns in PGA passwords, the researchers developed an attack framework that is 'capable of cracking passwords on previously unseen pictures in a picture gesture authentication system.'"

mdsolar sends this quote from Bloomberg: "More than 50 years into the age of nuclear energy, one of the biggest growth opportunities may be junking old reactors. Entergy Corp. (ETR) said Aug. 27 it will close its 41-year-old Vermont Yankee nuclear plant in 2014, making the reactor the fifth unit in the U.S. marked for decommissioning within the past 12 months, a record annual total. Companies that specialize in razing nuclear plants and hauling away radioactive waste are poised to benefit. Disposal work is 'where companies are going to make their fortune,' Margaret Harding, an independent nuclear-industry consultant based in Wilmington, North Carolina, said in an phone interview. Contractors that are usually involved in building reactors ... 'are going to be looking very hard at the decommissioning side of it.' [T]he U.S. nuclear fleet of 104 units is shrinking, even as Southern Co. and Scana Corp. build two units each. ... During a reactor decommissioning, the plant operator transfers radioactive fuel rods to cooling pools and, ultimately, to so-called dry casks for storage. Workers clean contaminated surfaces by sandblasting, chemical sprays and hydrolasing, a process that involves high-pressure water blasts, according to King. 'You do get to a point that you need someone to come in that has the equipment and the technology to actually dismantle the components,' she said. 'That typically is hired out.'"

The company said while published photos showed the FAB facility surrounded by smoke and engulfed in flames, 'the damage is not as severe as it seems as the smoke created was because the fire was concentrated in the air purification facilities that are linked to the rooftop of the fab.' The company also said that there is no material damage to the fab equipment in the clean room, and Hynix expects to resume operations in a short time period, so overall production and supply volume should not be 'materially affected.' Even so, the spot price of DRAM is expected to leap as a result of the news."

MojoKid writes "Low-power parts for hand-held devices may be all the rage right now, but today Intel is taking the wraps off a new high-end desktop processor with the official unveiling of its Ivy Bridge-E microarchitecture. The Core i7-4960X Extreme Edition processor is the flagship product in Intel's initial line-up of Ivy Bridge-E based CPUs. The chip is manufactured using Intel's 22nm process node and features roughly 1.86 billion transistors, with a die size of approximately 257mm square. That's about 410 million fewer transistors and a 41 percent smaller die than Intel's previous gen Sandy Bridge-E CPU. The Ivy Bridge-E microarchitecture features up to 6 active execution cores that can each process two threads simultaneously, for support of a total of 12 threads, and they're designed for Intel's LGA 2011 socket. Intel's Core i7-4960X Extreme Edition processor has a base clock frequency of 3.6GHz with a maximum Turbo frequency of 4GHz. It is easily the fastest desktop processor Intel has released to date when tasked with highly-threaded workloads or when its massive amount of cache comes into play in applications like 3D rendering, ray tracing, and gaming. However, assuming similar clock speeds, Intel's newer Haswell microarchitecture employed in the recently released Core i7-4770K (and other 4th Gen Core processors) offers somewhat better single-core performance."

MojoKid writes "The story around AMD's upcoming Kaveri continues to evolve, but it's increasingly clear that AMD's 3rd generation APU won't be available for retail purchase this year. If you recall, AMD initially promised that Kaveri would be available during 2013 and even published roadmaps earlier in May that show the chip shipping in the beginning of the fourth quarter. What the company is saying now is that while Kaveri will ship to manufacturers in late 2013, it won't actually hit shelves until 2014. The reason Kaveri was late taping out, according to sources, was that AMD kept the chip back to put some additional polish on its performance. Unlike Piledriver, which we knew would be a minor tweak to the core Bulldozer architecture, Steamroller, Kaveri's core architecture, is the first serious overhaul to that hardware. That means it's AMD's first chance to really fix things. Piledriver delivered improved clock speeds and power consumption, but CPU efficiency barely budged compared to 'Dozer. Steamroller needs to deliver on that front."

So, with all those fancy iPads at their schools, today's kids must really be programming up a storm, right? Wrong. Nichols, who's currently pursuing a PhD in education, laments, 'The iPad is among the recent panaceas being peddled to schools, but like those that came before, its ostensibly subversive shell houses a fairly conventional approach to learning. Where Texas Instruments graphing calculators include a programming framework accessible even to amateurs, writing code for an iPad is restricted to those who purchase an Apple developer account, create programs that align with Apple standards, and submit their finished products for Apple's approval prior to distribution.'"

Quoting: 'Japan has been very lucky that nothing worse has occurred at the plant. But luck eventually runs out. The longer Tepco stays in charge of the decommissioning process, the worse the odds become. Without downplaying the seriousness of leaks and the other setbacks at the plant, it is important to recognize that things could very quickly get much worse. In November, Tepco plans to begin the delicate operation of removing spent fuel from Reactor No. 4. There are 1,300 used fuel rod assemblies in a pool above the reactor. They weigh a total of 400 tons, and contain radiation equivalent to 14,000 times the amount released by the Hiroshima atomic bomb. The spent-fuel pool, standing 18 meters above ground, was damaged by the earthquake and tsunami and is in a deteriorating condition. It remains vulnerable to any further shocks, and is also at risk from ground liquefaction. Removing its spent fuel, which contains deadly plutonium, is an urgent task.'"

At its Intel Developers Forum next month in San Francisco, Intel has scheduled an information session on overclocking SSDs. The IDF session is aimed at system manufacturers and developers as well as do-it-yourself enthusiasts, such as gamers. 'We've debated how people would use it. I think the cool factor is somewhat high on this, but we don't see it changing the macro-level environment. But, as far as being a trendsetter, it has potential,' said Intel spokesman Alan Frost.

Interesting, but we will have to see how much performance and capacity [it has] over existing solutions,' Yang said in an email reply to Computerworld."
Nerval's Lobster writes "For quite some time, some economists and social scientists have argued that advances in robotics and computer technology are systematically wrecking the job prospects of human beings. Back in June, for example, an MIT Technology Review article detailed Erik Brynjolfsson (a professor at the MIT Sloan School of Management) and a co-author suggesting that the evolution of computer technology was "largely behind the sluggish employment growth of the last 10 to 15 years." Of course, technological change and its impact on the workforce is nothing new; just look at the Industrial Revolution, when labor-saving devices put many a hard-working homo sapien out of economic commission. But how far can things go? There are even arguments that the technology behind Google's Self-Driving Car, which allows machines to rapidly adapt to situations, could put whole new subsets of people out of jobs."
cartechboy writes "As Nissan develops autonomous cars for its 2020 target date, the company's engineers are modeling the tech after behaviors seen in bumblebees and fish. Nissan actually tests self-navigation algorithms in seven small toy-looking robots called EPORO. The robots have 180-degree vision (modeled after bees) and monitor each others' positions, travel nose to nose and avoid collisions--just like a school of fish. Getting small robots to zip around without bumping into things might be the first step in getting cars to do the same."
An anonymous reader notes that Skype is reportedly working on a 3D version of its messaging application. As reported by the BBC, an unnamed senior executive says that rumors to this effect are true. However, don't get too worked up about sending your avatar to school or to work just yet: Microsoft's corporate vice-president for Skype, Mark Gillett, says that "the capture devices are not yet there. As we work with that kind of technology you have to add multiple cameras to your computer, precisely calibrate them and point them at the right angle. ... We have it in the lab, we know how to make it work and we're looking at the ecosystem of devices and their capability to support it in order to make a decision when we might think about bringing something like that to market."

Joe Marine of No Film School has a short interview with two of the creators of the Black Betty, a deceptively old-school looking digital cinema camera. The Black Betty gets around one issue with the massive data processing and storage needs inherent to high-capacity, high-resolution video cameras by attacking it head-on. Rather than use the camera "merely" as a collection device, the creators have jammed into the machined aluminum case the guts of a Mac Mini, which means the camera not only has a powerful processing brain, but a built-in SSD drive, and can (in a pinch, or even by preference in the field) be used to edit and transmit the footage collected with the actual imaging system, which is based around the SI-2K Mini sensor, which shoots 1080p video at up to 30fps.
MarkWhittington writes "Tony Milligan is a teaching fellow of philosophy at the University of Aberdeen and is apparently concerned about helium 3 mining on the moon. In a recent paper he suggested that it should not be allowed for a number of reasons which include environmental objections, his belief that the moon is a cultural artifact, and that too much access to energy would be bad for the human race."
AmiMoJo writes "Japan's nuclear regulators have raised the level of severity of the radioactive water leak from a tank at the Fukushima Daiichi nuclear plant. It is now a level-3 serious incident. The revision from level 1 is based on estimates of the volume of radioactive substances leaked. The International Atomic Energy Agency supports the revision. They say the tank leak can be assessed separately from the Fukushima Daiichi crisis as a level 3 incident. Japanese experienced a level-3 nuclear event in 1997 with the fire and explosions at a fuel reprocessing plant in Tokai Village, Ibaraki Prefecture. 37 workers there were exposed to the leaked radioactive substances."
stomv writes "Vermont Yankee nuclear plant is to close in late 2014, about 20 years before its (extended) NRC operating permit expires in 2032. Vermont Yankee is a merchant plant, which means that it sells its energy and capacity on the open New England market. The three reasons cited by Entergy, the owner, for closing are: low natural gas prices, high ongoing capital costs of operating a single unit reactor, and wholesale market flaws which keep energy and capacity prices low and doesn't reward the fuel diversity benefits that nuclear provides."
ananyo writes "Facebook can lose a few users and remain a perfectly stable network, but where the national grid is concerned, simple geography dictates that it is always just a few transmission lines from collapse, according to a mathematical study of spatial networks. The upshot of the study is that spatial networks are necessarily dependent on any number of critical nodes whose failure can lead to abrupt — and unpredictable — collapse. The warning comes ten years after a blackout that crippled parts of the midwest and northeastern United States and parts of Canada. In that case, a series of errors resulted in the loss of three transmission lines in Ohio over the course of about an hour. Once the third line went down, the outage cascaded towards the coast, cutting power to some 50 million people. The authors say that this outage is an example of the inherent instability the study describes. But others question whether the team's conclusions can really be extrapolated to the real world. 'The problem is that this doesn't reflect the physics of how the power grid operates,' says Jeff Dagle, an electrical engineer at the Pacific Northwest National Laboratory in Richland, Washington, who served on the government task force that investigated the 2003 outage."
cartechboy writes "Two Ph.D. students from MIT have created a keyboard accessory, the Pavlov Poke, that shocks you every time you go onto Facebook. The project comes as a result of the students finding the waste over 50 hours a week combined on the social network (instead of working on their dissertations) So the pair created an Arduino-based keyboard hand-rest that shocks computer users who spend too much time checking the social network. The hack is 'intended to generate discussion' — not actually turn into a business." Inventor Robert Morris describes it as "something of a joke," but I'm sure there's a market out there.
jarold writes to point out an intriguing entry in the expanding smart-watch field: the Omate TrueSmart watch. Production of samples is about start on the watch after a successful Kickstarter campaign. Unlike some of the smart watches now out (or promised for soon), the TrueSmart is capable of making voice calls, sending texts, and using social media messaging without a separate smartphone or tablet. The specs are impressive, for something you wear on your wrist: Android 4.2.2 running on a dual core Cortex A7 and half a gig of RAM, 4GB of storage (expandable via micro-SD slot).
