BitTorrent Sees Sync Users Share Over 1PB of Data 56

An anonymous reader writes with an update on the rapid adoption of BitTorrent Lab's Sync tool. From the article: "BitTorrent on Monday announced an impressive milestone for its file synchronization tool Sync: users have synced over 1PB of data. The company says over 70 terabytes are synced via the tool every day. BitTorrent first announced its Sync software back in January and released a private alpha. Between then and April 23, when the company release a public alpha, users synced over 200TB worth of data. In other words, over the past 13 days users have synced over 800TB of data. At this rate, the service will pass 10PB before even hitting a stable release."

Intel Details Silvermont Microarchitecture For Next-Gen Atoms 82

crookedvulture writes "Since their debut five years ago, Intel's low-power Atom microprocessors have relied on the same basic CPU core. That changes with the next generation, which will employ an all-new Silvermont microarchitecture built using a customized version of Intel's tri-gate, 22-nm fabrication process. Silvermont ditches the in-order design of previous Atoms in favor of an out-of-order approach based on a dual-core module equipped with 1MB of shared L2 cache. The design boasts improved power sharing between the CPU and integrated graphics, allowing the CPU cores to scale up to higher speeds depending on system load and platform thermals. Individual cores can be shut down completely to provide additional clock headroom or to conserve power. Intel claims Silvermont doubles the single-threaded performance of its Saltwell predecessor at the same power level, and that dual-core variants have lower peak power draw and higher performance than quad-core ARM SoCs. Silvermont also marks the Atom's adoption of the 'tick-tock' update cadence that guides the development of Intel's Core processors. The successor to Silvermont will be built on 14-nm process tech, and an updated microarchitecture is due after that."

A Mask That Can Give You Superhuman Abilities 68

An anonymous reader writes "The students at Royal College of Art in London have developed masks that can increase your sight and hearing senses. They allow you to choose one conversation or one visual among a cluster of sounds and visuals, then hear or see the one which you want to. There are two masks developed by them: Eidos Vision and Eidos Audio. Eidos Audio allows a wearer to hear a specific conversation in a crowd and could be developed as a hearing aid and help ADHD sufferers. Eidos Vision improves vision allowing wearer to see 'time trails' similar to a timelapse photography."

Syria Buys Dell PCs Despite Sanctions 72

puddingebola writes with a New York Times article about how mundane PC equipment — not just more esoteric and eyebrow-raising network monitoring equipment from Blue Coat — makes its way to Syria: "Large amounts of computer equipment from Dell have been sold to the Syrian government through a Dubai-based distributor despite strict trade sanctions intended to ban the selling of technology to the regime, according to documents obtained by The New York Times. The disclosure of the computer sales is the latest example of how the Syrian government has managed to acquire technology, some of which is used to censor Internet activity and track opponents of the Syrian president, Bashar al-Assad."

India's $20 Android Tablet First Project Completed 42

symbolset writes "Though there were some troubles and worries along the way, Datawind has delivered to India's government the full allocation of 100,000 (1 lakh) 'Aakash 2' Android tablets from their first order. Priced at about $40, these tablets aren't the sort Americans would rave about: 330 MHz, 256MB RAM and so on. But for the last 2,000 units for the same price Datawind supplied Aakash 3 1GHz, 1GB RAM, 4GB Android tablets with SDHC and 3G mobile — for the same price. Such is the progress in mobile today. There was some doubt whether Datawind could deliver, so kudos to them."

Staples Starts Selling 3-D Printer 65

An anonymous reader writes "Soon anyone will be able to head out to the store and buy a 3D printer: 'Staples, one of the leading office supply retailers in the U.S. announced it would begin selling 3-D Systems' entry level personal 3-D printer, The Cube. This is quite simply the single largest 3-D printer retail move to date by any 3-D printer manufacturer.' 'The Cube is one of a number of 3-D printers designed with traditional consumers in mind. Specifically, this unit can print items up to 5.5 inches tall, wide and long in one of 16 different colors. The retail bundle includes 25 free design templates to get users started but the real fun is designing and building something all your own.'"

Is Buying an Extended Warranty Ever a Good Idea? 329

waderoush writes "Consumer Reports calls extended warranties 'money down the drain,' and as a tech journalist and owner of myriad gadgets — none of which have ever conked out or cracked up during the original warranty period — that was always my attitude too. But when I met recently with Steve Abernethy, CEO of San Francisco-based warranty provider SquareTrade, I tried to keep an open mind, and I came away thinking that the industry might be changing. In a nutshell, Abernethy says he's aware of the extended-warranty industry's dreadful reputation, but he says SquareTrade is working to salvage it through a combination of lower prices, broader coverage, and better service. On top of that, he made some persuasive points – which don't seem to figure into Consumer Reports' argument – about the way the 'risk vs. severity' math has changed since the beginning of the smartphone and tablet era. One-third of smartphone owners will lose their devices to drops or spills within the first three years of purchase, the company's data shows. If you belong to certain categories — like people in big households, or motorcycle owners, or homeowners with hardwood floors — your risk is even higher. So, in the end, the decision about buying an extended warranty boils down to whether you think you can defy the odds, and whether you can afford to buy a new device at full price if you're one of the unlucky ones."

Robot 'Fly' Mimics Full Range of Insect Flight 41

ananyo writes "A robot as small as a housefly has managed the delicate task of flying and hovering the way the actual insects do. The device uses layers of ultrathin materials that can make its wings flap 120 times a second, similar to the rate that a housefly manages. The robot's wings are composed of thin polyester films reinforced with carbon fibre ribs and its 'muscles' are made from piezoelectric crystals, which shrink or stretch depending on the voltage applied to them. Weighing in at just 80 milligrams, the tiny drone cannot carry its own power source, so has to stay tethered to the ground. It also relies on a computer to monitor its motion and adjust its attitude (abstract). Still, it is the first robot to deploy a fly's full range of aerial motion, including hovering (there's a video in the source)."

The Smart Grid Has Arrived 121

A reader sends this excerpt from MIT's Technology Review: "The first comprehensive and large scale smart grid is now operating. The $800 million project, built in Florida, has made power outages shorter and less frequent, and helped some customers save money, according to the utility that operates it. ... Dozens of utilities are building smart grids — or at least installing some smart grid components, but no one had put together all of the pieces at a large scale. Florida Power & Light's project incorporates a wide variety of devices for monitoring and controlling every aspect of the grid, not just, say, smart meters in people's homes. ... Many utilities are installing smart meters — Pacific Gas & Electric in California has installed twice as many as FPL, for example. But while these are important, the flexibility and resilience that the smart grid promises depends on networking those together with thousands of sensors at key points in the grid — substations, transformers, local distribution lines, and high voltage transmission lines. (A project in Houston is similar in scope, but involves half as many customers, and covers somewhat less of the grid.) In FPL's system, devices at all of these places are networked — data jumps from device to device until it reaches a router that sends it back to the utility — and that makes it possible to sense problems before they cause an outage, and to limit the extent and duration of outages that still occur. The project involved 4.5 million smart meters and over 10,000 other devices on the grid."

Lenovo To Drop Iomega Brand On Joint EMC Products 58

FrankPoole writes "The Iomega brand name will soon be officially laid to rest. Lenovo and EMC, which jointly own the storage company, will replace the Iomega name on all NAS products with 'LenovoEMC.' Lenovo and EMC entered into a joint venture last year, with Lenovo buying partial ownership of Iomega. But because the company name is associated with cheap, consumer storage and ZIP drives, Lenovo is giving Iomega the boot."

Haswell Integrated Graphics Promise 2-3X Performance Boost 133

crookedvulture writes "Intel has revealed fresh details about the integrated graphics in upcoming Haswell processors. The fastest variants of the built-in GPU will be known as Iris and Iris Pro graphics, with the latter boasting embedded DRAM. Unlike Ivy Bridge, which reserves its fastest GPU implementations for mobile parts, the Haswell family will include R-series desktop chips with the full-fat GPU. These processors are likely bound for all-in-one systems, and they'll purportedly offer close to three times the graphics performance of their predecessors. Intel says notebook users can look forward to a smaller 2X boost, while 15-17W ultrabook CPUs benefit from an increase closer to 1.5X. Haswell's integrated graphics has other perks aside from better performance, including faster Quick Sync video transcoding, MJPEG acceleration, and support for 4K resolutions. The new IGP will support DirectX 11.1, OpenGL 4.0, and OpenCL 1.2, as well." Note: Same story, different words, at Extreme Tech and Hot Hardware.

Energy Production Is As 'Dirty' As Ever 260

kkleiner writes "A recent report (PDF) from International Energy Agency delivers some dire news: despite 20 years of efforts toward clean energy and a decade of growth in renewable energy, energy production remains as 'dirty' as ever due to worldwide reliance on fossil fuels. With the global demand for energy expected to rise by 25 percent in the next 10 years, a renewed effort toward cleaner energy is desperately needed to avoid detrimental effects to the environment and public health. The report says, 'Coal technologies continue to dominate growth in power generation. This is a major reason why the amount of CO2 emitted for each unit of energy supplied has fallen by less than 1% since 1990. Thus the net impact on CO2 intensity of all changes in supply has been minimal. Coal-fired generation, which rose by an estimated 6% from 2010 to 2012, continues to grow faster than non-fossil energy sources on an absolute basis.'"

Google Glass Is the Future — and the Future Has Awful Battery Life 473

zacharye writes "The concept of wearable tech is really buzzing right now as pundits tout smart eyewear, watches and other connected devices as the future of tech. It makes sense, of course — smartphone growth is slowing and people need something to hold on to — but the early 'Explorer' version of Google's highly anticipated Google Glass headset has major problem that could be a big barrier for widespread adoption: Awful battery life." Also, a review of the hardware. The current Glass hardware heads south in less than five hours, which doesn't seem too short relative to similarly powerful devices, but since it is meant to be worn all the time you'd think it would have a large enough battery to make it at least 8 or 10 hours.

Carnegie Mellon Offers Wee QWERTY Texting Tech For Impossibly Tiny Devices 100

coondoggie writes "If smartwatches and other ultra-small devices are to become the text generators of the future, their diminutive keyboards are going to have to be way more useful for, um, big fingered typists. Carnegie Mellon researchers may have the answer to that problem. Called ZoomBoard, the text entry technique is based on the iconic QWERTY keyboard layout." The zoom board paper (PDF) has details. Entering a letter becomes a multi-step process; first you mash the general area of the keyboard containing the letter you want, and eventually it becomes large enough to hit. Test subjects managed to hit 9.3wpm after practice, versus 4.5 wpm for people trying to peck on a teeny-tiny virtual keyboard. They were inspired at least in part by the venerable Dasher input method.

Ask Slashdot: What If We Don't Run Out of Oil? 663

symbolset writes "The Atlantic recently ran an in-depth article about energy resources. The premise is that there remain incalculable and little-understood carbon fuel assets which far outweigh all the fossil fuels ever discovered. The article lists them and discusses their potentials and consequences, both fiscal and environmental. 'The clash occurs when renewables are ready for prime time—and natural gas is still hanging around like an old and dirty but reliable car, still cheap to produce and use, after shale fracking is replaced globally by undersea mining of methane hydrate. Revamping the electrical grid from conventionals like coal and oil to accommodate unconventionals like natural gas and solar power will be enormously difficult, economically and technically.' Along these lines, yesterday the U.S. Geological Survey more than doubled their estimate of Bakken shale oil reserve in North Dakota and Montana to 7.4-11 billion barrels. Part of the push for renewables over the past few decades was the idea that old methods just weren't going to last. What happens to that push if fossil fuels remain plentiful?"

FSF Certifies Atheros-Based ThinkPenguin 802.11 N USB Adapter 85

gnujoshua writes "You may recall that last Fall, the LulzBot AO-100 3D printer was awarded the use of the Free Software Foundation's Respects Your Freedom certification mark. Today, the FSF announced certification of the ThinkPenguin TPE-N150USB, Wireless N USB Adapter, which uses the Atheros ARAR9271 chip. The FSF's RYF certification requirements are focused on the software (not the hardware designs) of a product, which in this case was primarily the device firmware and ath9k-htc module in the Linux-libre kernel. (Disclosure: I work for the FSF.) There's also a cool story that is within this story... which is that the firmware for the Atheros AR9271 chipset was released as a result of a small device seller (ThinkPenguin) striking a deal with a large electronic device manufacturer (Qualcomm Atheros) to build a WLAN USB adapter that shipped with 100% free software firmware. This deal was possible largely because two motivated Qualcomm Atheros employees, Adrian Chadd and Luis Rodriguez, made the internal-push to get the firmware released as free software."

High End Graphics Cards Tested At 4K Resolutions 201

Vigile writes "One of the drawbacks to high end graphics has been the lack of low cost and massively-available displays with a resolution higher than 1920x1080. Yes, 25x16/25x14 panels are coming down in price, but it might be the influx of 4K monitors that makes a splash. PC Perspective purchased a 4K TV for under $1500 recently and set to benchmarking high end graphics cards from AMD and NVIDIA at 3840x2160. For under $500, the Radeon HD 7970 provided the best experience, though the GTX Titan was the most powerful single GPU option. At the $1000 price point the GeForce GTX 690 appears to be the card to beat with AMD's continuing problems on CrossFire scaling. PC Perspective has also included YouTube and downloadable 4K video files (~100 mbps) as well as screenshots, in addition to a full suite of benchmarks."

AMD Details Next-Gen Kaveri APU's Shared Memory Architecture 128

crookedvulture writes "AMD has revealed more details about the unified memory architecture of its next-generation Kaveri APU. The chip's CPU and GPU components will have a shared address space and will also share both physical and virtual memory. GPU compute applications should be able to share data between the processor's CPU cores and graphics ALUs, and the caches on those components will be fully coherent. This so-called heterogeneous uniform memory access, or hUMA, supports configurations with either DDR3 or GDDR5 memory. It's also based entirely in hardware and should work with any operating system. Kaveri is due later this year and will also have updated Steamroller CPU cores and a GPU based on the current Graphics Core Next architecture." bigwophh writes links to the Hot Hardware take on the story, and writes "AMD claims that programming for hUMA-enabled platforms should ease software development and potentially lower development costs as well. The technology is supported by mainstream programming languages like Python, C++, and Java, and should allow developers to more simply code for a particular compute resource with no need for special APIs."
