Nano-Pixels Hold Potential For Screens Far Denser Than Today's Best 129

Posted by timothy
from the enhance-enhance-enhance dept.
Zothecula (1870348) writes "The Retina displays featured on Apple's iPhone 4 and 5 models pack a pixel density of 326 ppi, with individual pixels measuring 78 micrometers. That might seem plenty good enough given the average human eye is unable to differentiate between the individual pixels, but scientists in the UK have now developed technology that could lead to extremely high-resolution displays that put such pixel densities to shame."

Slashdot Asks: Do You Want a Smart Watch? 381

Posted by timothy
from the does-it-shoot-deadly-darts? dept.
Watches that do more than tell the time have been around for a long time. (And in fiction, James Bond, Dick Tracey, and Michael Knight all had notably high-tech watches.) The new smart watches from Samsung and LG, without a phone connected via Bluetooth as backhaul, can still serve to show the time and to serve as alarms (and Samsung's can measure your pulse, too), but all the magic features (like searching by voice via the watch) do require a connection. They can't play MP3s or take pictures on their own, and they don't have built-in GPS. Even so, compared to the polarizing Google Glass, the new breed of smart watches are wearables that probably are an easier sell, even if this far the trend has been to replace watches with smart phones. (Android Wear has gotten a lot of attention, but Microsoft has their own upcoming, and Apple almost certainly does, too.) Are you interested in a smart watch, and if so, what uses do you want it for? If they have no appeal to you now, are there functions that would make you change your mind on that front?

Sand-Based Anode Triples Lithium-Ion Battery Performance 60

Posted by timothy
from the but-where-will-it-comes-from? dept.
Zothecula (1870348) writes "Conventional lithium-ion batteries rely on anodes made of graphite, but it is widely believed that the performance of this material has reached its zenith, prompting researchers to look at possible replacements. Much of the focus has been on nanoscale silicon, but it remains difficult to produce in large quantities and usually degrades quickly. Researchers at the University of California, Riverside have overcome these problems by developing a lithium-ion battery anode using sand."

Ode To Sound Blaster: Are Discrete Audio Cards Still Worth the Investment? 502

Posted by timothy
from the won't-fit-in-my-phone dept.
MojoKid (1002251) writes "Back in the day (which is a scientific measurement for anyone who used to walk to school during snowstorms, uphill, both ways), integrated audio solutions had trouble earning respect. Many enthusiasts considered a sound card an essential piece to the PC building puzzle. It's been 25 years since the first Sound Blaster card was introduced, a pretty remarkable feat considering the diminished reliance on discrete audio in PCs, in general. These days, the Sound Blaster ZxR is Creative's flagship audio solution for PC power users. It boasts a signal-to-noise (SNR) of 124dB that Creative claims is 89.1 times better than your motherboard's integrated audio solution. It also features a built-in headphone amplifier, beamforming microphone, a multi-core Sound Core3D audio processor, and various proprietary audio technologies. While gaming there is no significant performance impact or benefit when going from onboard audio to the Sound Blaster ZxR. However, the Sound Blaster ZxR produced higher-quality in-game sound effects and it also produces noticeably superior audio in music and movies, provided your speakers can keep up."

Apple Gets Its First Batch of iPhone Chips From TSMC 45

Posted by timothy
from the pronounced-just-like-it-looks dept.
redletterdave (2493036) notes that Taiwan Semiconductor Manufacturing Co. (TSMC) has shipped its first batch of microprocessors to Apple as the iPhone maker looks to diversify its overseas suppliers. Apple will continue to rely on Samsung for its microprocessors, but as the rivalry between Apple and Samsung heats up in the mobile and soon wearable arenas, the deal with TSMC allows Apple to be less reliant on Samsung and therefore have more leverage with respect to price negotiations for future chips, as TSMC has supplanted Samsung Electronics as Apple's chief chipmaker for iPhones and iPads. Since 2011, Apple has been striking deals with other display and chip makers around Asia to reduce its dependence on Samsung. As a result of this slowdown in sales, Samsung on Monday announced operating income for its fiscal second quarter had sunk to a two-year low, blaming 'weak' sales of low- and medium-end smartphones, strong competition and subpar demand.
It may not be a household name like Intel or AMD, but TSMC is the world's biggest chip maker by revenue.

Hacking a Tesla Model S Could Net $10,000 Prize 77

from the usb-port-under-the-gas-cap dept.
cartechboy (2660665) writes "It seems there's a new hack challenge set every week, but this time, it seems different. A challenge has been thrown down to hack a Tesla Model S with a $10,000 prize. The organizers of a computer security conference have set the challenge and it's open to anyone that registers for the Syscan conference. Taking place in Beijing from July 16-17, the rules for the hack competition haven't been revealed yet but a Model S will be on display for hackers to try their luck on. It's important to note that Tesla itself isn't involved in the competition in any official capacity, nor does it support the competition. If successful, this wouldn't be the first time a Tesla Model S has been hacked. In that instance Tesla was quick to warn people that making changes in the Model S' software would immediately void the car's warranty. Given the car's high-tech nature, it's no shock Tesla's taking security seriously. With $10,000 on the line, it'll be interesting to see if anyone manages to crack the code."

IBM To Invest $3 Billion For Semiconductor Research 68

Posted by samzenpus
from the big-bucks dept.
Taco Cowboy points out that many news outlets are reporting that IBM plans to spend $3 billion on semiconductor research and development in the next five years. The first goal is to build chips whose electronic components, called transistors, have features measuring just 7 nanometers, the company announced Wednesday. For comparison, that distance is about a thousandth the width of a human hair, a tenth the width of a virus particle, or the width of 16 potassium atoms side by side. The second goal is to choose among a range of more radical departures from today's silicon chip technology -- a monumental engineering challenge necessary to sustain progress in the computing industry. Among the options are carbon nanotubes and graphene; silicon photonics; quantum computing; brainlike architectures; and silicon substitutes that could run faster even if components aren't smaller. "In the next 10 years, we believe there will be fundamentally new systems that are much more efficient at solving problems or solving problems that are unsolvable today," T.C. Chen, IBM Research's vice president of science and technology, told CNET

An anonymous reader writes "I'm a Solaris user which is not well supported by the OSS toolchains. I'd like to have a dedicated Linux based dev system which has good support for ARM, MSP430 and other MCU lines and draws very little (5-10 watts max) power. The Beaglebone Black has been suggested. Is there a better choice? This would only be used for software development and testing for embedded systems."

mdsolar sends this story from the NY Times: Here's what your future will look like if we are to have a shot at preventing devastating climate change. Within about 15 years every new car sold in the United States will be electric. ... Up to 60 percent of power might come from nuclear sources. And coal's footprint will shrink drastically, perhaps even disappear from the power supply. This course, created by a team of energy experts, was unveiled on Tuesday in a report for the United Nations (PDF) that explores the technological paths available for the world's 15 main economies to both maintain reasonable rates of growth and cut their carbon emissions enough by 2050 to prevent climatic havoc. It offers a sobering conclusion: We might be able to pull it off. But it will take an overhaul of the way we use energy, and a huge investment in the development and deployment of new energy technologies. Significantly, it calls for an entirely different approach to international diplomacy on the issue of how to combat climate change.

How Japan Lost Track of 640kg of Plutonium 104

Posted by Soulskill
from the left-it-in-my-other-pants dept.
Lasrick sends this quote from the Bulletin of the Atomic Scientists: Most people would agree that keeping track of dangerous material is generally a good idea. So it may come as a surprise to some that the arrangements that are supposed to account for weapon-grade fissile materials—plutonium and highly enriched uranium—are sketchy at best. The most recent example involves several hundreds kilograms of plutonium that appear to have fallen through the cracks in various reporting arrangements. ... [A Japanese researcher discovered] that the public record of Japan’s plutonium holdings failed to account for about 640 kilograms of the material. The error made its way to the annual plutonium management report that Japan voluntarily submits to the International Atomic Energy Agency ... This episode may have been a simple clerical error, but it was yet another reminder of the troubling fact that we know very little about the amounts of fissile material that are circulating around the globe. The only reason the discrepancy was discovered in this case was the fact that Japan has been unusually transparent about its plutonium stocks. ... No other country does this.

BlackBerry's Innovation: Square-Screened Smartphones 139

Posted by Soulskill
from the bet-you-didn't-know-you-needed-that dept.
EthanV2 sends word that BlackBerry, having finally caught up to a world dominated by smartphones, is now trying to push the envelope by developing a smartphone with a square screen. The BlackBerry Passport has a 4.5-inch screen with a resolution of 1440x1440. The phone has a physical keyboard as well. In a blog post about the new phone, they show a picture with it side-by-side with an iPhone and a Galaxy S5 — the Passport is slightly taller than the iPhone, and significantly wider, as you'd expect. The Passport is a play for BlackBerry's "traditional" work-oriented user base, where the earlier BlackBerry Z10 and Z30 were efforts to break into the post-iPhone consumer smartphone space. Though the Passport may well be preferable for spreadsheets and word processing, that square screen will be much less useful for widescreen movies, and its wide, blocky design will entirely prohibit one-handed use. The Passport is expected to appear later this year, and it will launch with BlackBerry 10.3 (at least, according to early hands-on previews).

All Web Developers Should Have Access to a Device Lab (Video) 60

from the still-working-on-making-website-standards-after-all-these-years dept.
This interview with Googler Pete LePage took place at Google I/O 2014, where Pete and coworker Matt Gaunt set up a Device Lab with 46 different devices on their display wall. The point wasn't to show off Google's coolness as much as it was to let developers see how their websites displayed on as wide a range of mobile devices as possible. This is reminiscent of the last century's Any Browser campaign, which was set up to encourage developers to make sites that worked right in any browser instead of having a WWW full of sites "best viewed in Exploroscape" that displayed poorly in other browsers.

Today, the trick is to make a site that is fully functional across a wide range of devices with different size screens that a user might decide to view in landscape mode one day and portrait mode the next. Google is happy to share their MiniMobileDeviceLab with you to help set up multi-unit displays. Pete also suggests checking out PageSpeed Insights and Web Fundamentals even if you're a skilled and experienced Web designer, because those two Google sites are chock full of information on how to make sure your site works right on most devices and in most popular browsers.

from the human-workers-sent-to-protein-bank dept.
redletterdave (2493036) writes The largest private employer in all of China and one of the biggest supply chain manufacturers in the world, Foxconn announced it will soon start using robots to help assemble devices at its several sprawling factories across China. Apple, one of Foxconn's biggest partners to help assemble its iPhones, iPads, will be the first company to use the new service. Foxconn said its new "Foxbots" will cost roughly $20,000 to $25,000 to make, but individually be able to build an average of 30,000 devices. According to Foxconn CEO Terry Gou, the company will deploy 10,000 robots to its factories before expanding the rollout any further. He said the robots are currently in their "final testing phase."

Intelligent Thimble Could Replace the Mouse In 3D Virtual Reality Worlds 65

Posted by Unknown Lamer
from the ring-of-wizardy dept.
New submitter anguyen8 (3736553) writes with news of an interesting experimental spatial input device. From the article: "The mouse is a hugely useful device but it is also a two-dimensional one. But what of the three-dimensional world and the long-standing, but growing, promise of virtual reality. What kind of device will take the place of the mouse when we begin to interact in three-dimensions? Anh Nguyen and Amy Banic ... have created an intelligent thimble that can sense its position accurately in three-dimensions and respond to a set of pre-programmed gestures that allow the user to interact with objects in a virtual three-dimensional world. ... The result is the 3DTouch, a thimble-like device that sits on the end of a finger, equipped with a 3D accelerometer, a 3D magnetometer, and 3D gyroscope. That allows the data from each sensor to be compared and combined to produce a far more precise estimate of orientation than a single measurement alone. In addition, the 3DTouch has an optical flow sensor that measures the movement of the device against a two-dimensional surface, exactly like that inside an ordinary mouse." The prototype is wired up to an Arduino Uno, with a program on the host machine polling the device and converting the data into input events. A video of it in action is below the fold, a pre-print of the research paper is on arxiv, and a series of weblog entries explain some of the development.

Study: Global Warming Solvable If Fossil Fuel Subsidies Given To Clean Energy 385

Posted by Unknown Lamer
from the we're-doomed dept.
An anonymous reader writes A research team at the International Institute for Applied Systems Analysis in Laxenburg, Austria, says it has studied how much it would cost for governments to stick to their worldwide global warming goal. They've concluded that for "a 70 per cent chance of keeping below 2 degrees Celsius, the investment will have to rise to $1.2 trillion a year." Where to get that money? The researchers say that "global investment in energy is already $1 trillion a year and rising" with more than half going to fossil fuel energy. If those subsidies were spent on renewable energy instead, the researchers hypothesize that "global warming would be close to being solved."

schwit1 (797399) writes Louis Del Monte estimates that machine intelligence will exceed the world's combined human intelligence by 2045. ... "By the end of this century most of the human race will have become cyborgs. The allure will be immortality. Machines will make breakthroughs in medical technology, most of the human race will have more leisure time, and we'll think we've never had it better. The concern I'm raising is that the machines will view us as an unpredictable and dangerous species." Machines will become self-conscious and have the capabilities to protect themselves. They "might view us the same way we view harmful insects." Humans are a species that "is unstable, creates wars, has weapons to wipe out the world twice over, and makes computer viruses." Hardly an appealing roommate."
