An anonymous reader writes "A team of scientists says it has verified that quantum effects are indeed at work in the D-Wave processor, the first commercial quantum optimization computer processor. The team demonstrated that the D-Wave processor behaves in a manner that indicates that quantum mechanics has a functional role in the way it works. The demonstration involved a small subset of the chip's 128 qubits, but in other words, the device appears to be operating as a quantum processor."

malachiorion writes "The best thing to come out of the DARPA Robotics Challenge, so far, isn't the lineup of nifty rescue bots being developed by teams around the world, or even Boston Dynamics' incredible Atlas humanoid. It's the pumped-up version of Gazebo, the free, open-source robotics simulation software whose expansion and further development is being funded by DARPA. This article has a look at how the software was used in the recent virtual leg of the competition, as well as how it could change the way robotics R&D is conducted (and create more roboticists, with its low-cost, cloud-based architecture)."
snydeq writes "Open centers of grassroots innovation, hackerspaces offer opportunities to source talent, create goodwill, and push technology forward, writes Open Software Integrators' Phil Rhodes. 'I had the good fortune to be able to attend Maker Faire North Carolina this weekend in Raleigh, N.C. ... At this local Maker Faire, I was struck by the number of hackerspaces represented. The energy, buzz, and activity around their booths was captivating,' Rhodes writes. 'Amid all this buzz, it dawned on me that everyone should be excited about hackerspaces and what they represent, both for their local communities and the world. Although the hackerspace movement is growing rapidly, many people are still not familiar with them, where they are located, or what they do. So let's examine the hackerspace world and explore why you should give a crap about it.'"
rwise2112 writes "Apple proposes a solution to multiple port requirements within limited space: the two in one port. The port is described as a 'Combined Input Port,' where two different interfaces could be in one port. The input port includes an outer wall defining a receiving aperture, a substrate positioned within the receiving aperture. One set of contacts is configured to communicate with a first connector and the second set of contacts is configured to communicate with a second connector. Looks like another addition to the special Apple cable lineup."
angry tapir writes "Researchers at Microsoft Research have produced a prototype software system that can be used on smartphones to infer a user's mood. The 'MoodScope' system produced by researchers uses smartphone usage patterns to determine whether someone is happy, calm, excited, bored or stressed and could potentially add a new dimension to to mobile apps (as well as, as the researchers note, open up a Pandora's Box of privacy issues). The researchers created a low-power background service for iPhones and Android handsets that (with training) can offer reasonable detection of mood and offers and API that app developers could hook into."
astroengine writes "This summer, the Japan Aerospace Exploration Agency (JAXA) plans to launch two amazingly cute yet advanced, white-helmeted robots into space. Then an astronaut aboard the International Space Station (ISS) will attempt to converse with one of them. Robot astronaut Kirobo and backup robot Mirata were created as part of the Kibo Robot Project, a collaboration among Robo Garage, Toyota, the University of Tokyo and the Japan Aerospace Exploration Agency JAXA. They aim to send the robots with the JAXA mission to the ISS on Aug. 4."
symbolset writes "Ars is reporting that Microsoft XBox One Kinect will not work on Windows PCs. It uses a proprietary connector and an adaptor will not be available. If you want Kinect for your PC you will need to buy a 'Kinect for Windows' product. Although the Kinect 1.0 for XBox 360 also had a proprietary connector it came with a USB adaptor for compatibility with older versions of the 360 that lacked the new proprietary port and PC compatibility was quickly hacked up by third parties."
NVIDIA's Android-based gaming gaming handheld called SHIELD was to start shipping today to customers who had pre-ordered it. Reader MojoKid writes "Unfortunately, in its last round of QA work, NVIDIA uncovered a problem with a third-party component used in SHIELD and will be pushing the launch date out into July. NVIDIA is, however, allowing some members of the press to talk a bit about their experiences with a couple of Tegra 4-optimized games — namely Real Boxing and Blood Sword: Sword of Ruin — and also about an AR Drone controlled by SHIELD with a bird's eye view. The AR Drone streams video from its on-board HD camera to the SHIELD device as you fly. Just launching the thing high into the air and peering into trees or over the houses in the neighborhood is really cool."
snydeq writes "InfoWorld's Riyaj Shamsudeen offers an in-depth look at Oracle Database 12c, which he calls a 'true cloud database,' bringing a new level of efficiency and ease to database consolidation. 'In development for roughly four years, Oracle Database 12c introduces so many important new capabilities in so many areas — database consolidation, query optimization, performance tuning, high availability, partitioning, backup and recovery — that even a lengthy review has to cut corners. Nevertheless, in addition to covering the big ticket items, I'll give a number of the lesser enhancements their due,' writes Riyaj Shamsudeen. 'Having worked with the beta for many months, I can tell you that the quality of software is also impressive, starting with a smooth RAC cluster installation. As with any new software release, I did encounter a few minor bugs. Hopefully these have been resolved in the production release that arrived yesterday.'"
itwbennett writes "Slashdot readers will recall Foxconn's plans to staff its factories with an army of 1 million robot workers to offset rising labor costs. Well, now we have an update on those plans. Speaking at the company's shareholder meeting on Wednesday, Foxconn CEO Terry Gou said that there are 20,000 robotic machines currently at work in Foxconn factories. Ultimately, these robots will replace human assembly workers and 'our [human] workers will then become technicians and engineers,' Gou said."
Sabine Hauert writes "According to robotics researcher Simone Schürle from ETH Zurich's Multi-Scale Robotics Lab (MSRL), the OctoMag is a magnetic manipulation system that uses electromagnetic coils to wirelessly guide micro-robots for ophthalmic surgery. With this system, mobility experiments were conducted in which a micro-robot with a diameter of 285 um (about four times the width of a hair) was navigated reliably through the eye of a rabbit, demonstrating the feasibility of using this technology in surgical applications."
wiredmikey writes "Security response personnel at HP are 'actively working on a fix' for a potentially dangerous backdoor in older versions of its StoreOnce backup product line. The company's confirmation of what it describes as a 'potential security issue' follows the public disclosure that malicious hackers can use SSH access to perform full remote compromise of HP's StoreOnce backup systems. The SHA1 hash for the password was also published, putting pressure on HP to get a fix ready for affected customers. SecurityWeek has confirmed that it is relatively trivial to brute-force the hash to obtain the seven-character password. The HP StoreOnce product, previously known as HP D2D, provides disk backup and recovery to small- to midsize businesses, large enterprises, remote offices and cloud service providers."
An anonymous reader writes "If you have a fascination with old supercomputers, like I do, this project might tickle your interest: A functional simulation of a Cray X-MP supercomputer, which can boot to its old batch operating system, called COS. It's complete with hard drive and tape simulation (no punch card readers, sorry) and consoles. Source code and binaries are available. You can also read about the journey that got me there, like recovering the OS image from a 30 year old hard drive or reverse-engineering CRAY machine code to understand undocumented tape drive operation and disk file-systems."
An anonymous reader writes "Clones of the ARM processor intellectual property are again becoming available for free from the open source hardware community. ARM was rigorous in shutting cloners down in the past but the clones are rising again under codenames Amber, Storm and Atlas, albeit of older instruction set architectures."
bshell writes "The Verge has a great photo-essay about Tûranor PlanetSolar, the first boat to circle the globe with solar power. 'The 89,000 kg (nearly 100 ton) ship needs a massive solar array to capture enough energy to push itself through the ocean. An impressive 512 square meters (roughly 5,500 square feet) of photovoltaic cells, to be exact, charge the 8.5 tons of lithium-ion batteries that are stored in the ship's two hulls.' The boat is currently in NYC. Among other remarkable facts, the captain (Gérard d'Aboville) is one of those rare individuals who solo-rowed across both the Atlantic and Pacific Oceans, journeys that took 71 and 134 days, respectively. The piece has a lot of detail about control systems and design."
An anonymous reader writes "Earlier today, Nvidia released its latest graphics card: the Geforce GTX 760. A followup to last month's GTX 770 launch, the new GTX 760 is the fourth 700-series card since the company launched the GTX Titan back in February. Sporting 1,152 CUDA cores, 96 TMUs, 32 ROPS, a 256-bit memory interface that effectively runs at 6 GHz, a base clock of 980 MHz, and a Boost speed of up to 1,033 MHz, the newly-minted GTX 760 is offered at a price point of $250. Benchmark results are available from all the usual suspects: AnandTech, HotHardware, PC Magazine, PCPer, and Tom's Hardware. To make a long story short, Nvidia's new card edges out AMD's equally-priced Radeon HD 7950 Boost Edition, and even goes toe-to-toe with the $300 Radeon HD 7870 GHz Edition. Factoring out AMD's incredible Never Settle game bundles, and looking purely at performance, the GTX 670 allows Nvidia to cinch up the mainstream gaming price point." Reader crookedvulture adds, "The $250 card is an updated spin on an existing GPU, so it doesn't raise the bar dramatically. In fact, the GTX 760 achieves rough performance parity with the Radeon HD 7950 Boost, which costs just a little bit more. The situation is similar at around $400, where the contest between the GeForce GTX 770 and Radeon HD 7970 GHz Edition is a toss-up overall. These price/performance scatter plots paint the picture clearly. AMD has largely resolved its previous frame latency issues with new drivers, making the battle between GeForce and Radeon more about extras than performance. Nvidia offers software to optimize game settings and record gameplay sessions, while AMD includes download codes for recent games. You really can't go wrong either way."
Nerval's Lobster writes "The powerful, reliable combination of transistors and semiconductors in computer processors could give way to systems built on the way electrons misbehave, all of it contained in circuits that warp even the most basic rules of physics. Rather than relying on a predictable flow of electrons that appear to know whether they are particles or waves, the new approach depends on quantum tunneling, in which electrons given the right incentive can travel faster than light, appear to arrive at a new location before having left the old one, and pass straight through barriers that should be able to hold them back. Quantum tunneling is one of a series of quantum-mechanics-related techniques being developed as possible replacements for transistors embedded in semiconducting materials such as silicon. Unlike traditional transistors, circuits built by creating pathways for electrons to travel across a bed of nanotubes are not limited by any size restriction relevant to current manufacturing methods, require far less power than even the tiniest transistors, and do not give off heat or leak electricity as waste products, according to Yoke Khin Yap of Michigan Technological University, lead author of a paper describing the technique, which was published in the journal Advanced Materials last week."
An anonymous reader writes "A few weeks ago, Slashdot featured a cheap platform performing 80FFTs per second to recognize whistles. The platform is open hardware/open source and is aimed for sound processing projects. To this goal, the creator (limpkin) just implemented a simple proof of concept algorithm that will control your lighting once the platform listens to a particular word. A small video has been made to explain the basic concepts of sound recognition to encourage hobbyist to make their own."
curtwoodward writes "Formlabs raised nearly $3 million in a month for its new Form 1 3D printer, which uses stereolithography to make precise models and other physical objects out of photoreactive liquid polymer. But 3D Systems — the publicly traded company founded by the guy who invented that process — sued the startup for patent infringement. Formlabs recently announced that it would start shipping its pre-ordered Form 1 printers, and that was no coincidence: the two companies quietly entered into settlement talks in early May, and hope to have a deal done by September."
netbuzz writes "In a clever bit of self-promotion, the do-it-yourself repair evangelists at iFixit announced today that they will be giving away 1,776 free 'iPhone liberation kits' that will allow Apple customers access to the inner workings of their devices by replacing the difficult-to-remove pentalobe screws with standard Phillips screws. 'Get a free insurance policy,' iFixit says. 'In the unfortunate event that your iPhone needs repair, you will be set to make any necessary fix. For situations when you need to get the battery out of your iPhone as quickly as possible—such as after dropping the device into water—you will be ready.'"
