ananyo writes "Bits of data travelling the internet have a tough commute — they bounce back and forth between optical signal lines for efficient transmission and electrical signal lines for processing. All-optical routers would be more energy efficient, but their development has been hindered by a lack of optical memory devices. Now, researchers have developed just such a device (journal article abstract), paving the way towards a faster, more energy-efficient internet. The devices are based on optical cavities that can be switched between light-transmitting and light-blocking states to construct digital signals. Researchers have been working on such devices for several years, but previous versions used too much power and could not retain data long enough. The new memory cells use just 30 nanowatts of power, 300 times less than previous designs, and can retain data for one microsecond — long enough to support processing."

waderoush writes "You can forget all the talk about 'smart' and 'connected' TVs: nobody, not even Apple, has come up with an interface that's easy to use from 10 feet away. And you can drastically curtail your hopes that Roku, Boxee, Netflix, and other providers of free or cheap 'over the top' Internet TV service will take over the world: the cable and satellite companies and the content owners have mounted savvy and effective counterstrikes. But there's another technology that really will disrupt the TV industry: tablet computing. The iPad, in particular, is the first 'second screen' device that's good enough to be the first screen. This Xconomy column argues that in the near future, the big-screen TV will turn into a dumb terminal, and your tablet — with its easy-to-use touch interface and its 'appified' approach to organizing content — will literally be running the show in your living room." Using a tablet as a giant remote seems like a good idea, and a natural extension of iPhone and Android apps that already provide media-center control. Maybe I'm too easily satisfied, but the 10-foot interface doesn't seem as hopeless as presented here; TiVo, Apple, and others been doing a pretty good job of that for the past decade.
MojoKid writes "According to new reports [note: source article at DigiTimes], global HDD production capacity is getting ready to increase to 140-145 million units in the first quarter of 2012, or about 80 percent of where it was prior to when the floods hit Thailand manufacturing plants. HDD production was sitting around 175 million units in the third quarter of 2011 before the floods, after which time it quickly dropped to 120-125 million units. Since then, there's been a concerted effort to restore operations to pre-flood levels."
judgecorp writes "Nordic nations are all pitching for business from data centre owners, based on their countries' excellent network provision, plentiful electricity from renewable sources, and a climate where servers can be kept cool cheaply, using the ambient air temperature, with no need for chillers. A Swedish delegation is visiting California to lure other players to follow Facebook into Sweden. Meanwhile, Iceland now has a new multi-tenant data centre to join the existing Thor site, and Denmark has a container-park data centre for its financial industry."
An anonymous reader writes "A look back at two articles from 1995, touting high end computers and 'must haves.' How times have changed... ...'Memory (RAM): We seem to have convinced most manufacturers to adopt eight megabytes as standard, compared with four megabytes in 1994. Don't buy less than eight. The difference in performance between an eight megabyte machine and a four-megabyte machine can be dramatic.'"
Damien1972 writes "Conservationists have converted a remote-controlled plane into a potent tool for conservation. The drone — an HK Bixler equipped with cameras, sensors and GPS — has been used to map deforestation, count orangutans and elephants, and get a bird's eye view of hard-to-access forest areas. During their 4 days of testing in Sumatra, the drone flew 30 missions without a single crash. A mission, which typically lasts about 25 minutes, can cover 50 hectares. The drone, full equipped, costs less than $2,000."
retroworks writes "Great piece in The Atlantic by Kyle Wiens of IFIXIT.org, who visited and photographed the Molycorp Mountain Pass rare earth facility in California's Mojave Desert. The mine is the only source of rare earths in North America, one of the only alternatives to the mineral cartels in China, and one of the only sources for the key metals such as tantalum needed in cell phones. There is of course actually one other source of rare earth metals in the USA — recycled cell phones. Is the best 'state of the art' mining as good as the worst state of the art recycling? If the U.S. Department of Energy subsidizes the mine, will China open the floodgates and put it out of business? Or will electronics be manufactured with alternative materials before the mine ever becomes fully scaleable?"
itwbennett writes "Don't believe recent claims made by a blogger that non-functioning batteries in the Tesla Roadster cause the electric cars to be bricked, says IDC analyst Sam Jaffe. 'Here's the primary fact that the blogger in question doesn't understand: the Tesla battery pack is not a battery,' says Jaffe. 'It's a collection of more than 8,000 individual batteries. Each of those cells is independently managed. So there's only two ways for the entire battery pack to fail. The first is if all 8,000 cells individually fail (highly unlikely except in the case of something catastrophic like a fire). The second failure mechanism is if the battery management system tells the pack to shut down because it has detected a dangerous situation, such as an extremely low depth of discharge. If that's the case, all that needs to be done is to tow the vehicle to a charger, recharge the batteries and then reboot the battery management system. This is the most likely explanation for the five 'bricks' that the blogger claims to have heard about.'"
YokimaSun writes "Sony has today released the PSVita in the U.S. and Europe. The console comes with features such as dual touch pads at the front and rear, dual cameras at the front and rear, dual analog sticks, a 5-inch OLED screen, GPS, six-axis motion sensors and a three-axis electronic compass. The PSVita is Sony's attempt at stealing the thunder away from the 3DS but also bringing back the gamers lost to the likes of Android and iOS Devices. The PSVita in Japan sold massively on its first release week but since has struggled and sold less than the PSP. With this in mind sites like Amazon have been offering many different deals to entice people to buy the console. Can Sony stop homebrewers from taking over this console?"
New submitter rescrv writes "Key-value stores (like Cassandra, Redis and DynamoDB) have been replacing traditional databases in many demanding web applications (e.g. Twitter, Google, Facebook, LinkedIn, and others). But for the most part, the differences between existing NoSQL systems come down to the choice of well-studied implementation techniques; in particular, they all provide a similar API that achieves high performance and scalability by limiting applications to simple operations like GET and PUT. HyperDex, a new key-value store developed at Cornell, stands out in the NoSQL spectrum with its unique design. HyperDex employs a unique multi-dimensional hash function to enable efficient search operations — that is, objects may be retrieved without using the key (PDF) under which they are stored. Other systems employ indexing techniques to enable search, or enumerate all objects in the system. In contrast, HyperDex's design enables applications to retrieve search results directly from servers in the system. The results are impressive. Preliminary benchmark results on the project website show that HyperDex provides significant performance improvements over Cassandra and MongoDB. With its unique design, and impressive performance, it seems fittng to ask: Is HyperDex the start of NoSQL 2.0?"
angry tapir writes "Intel is exploring whether it can branch out as a foundry by opening its chip manufacturing facilities to more third-party customers. Intel has expanded its chip-to-order business by signing up additional customers to take advantage of its 22-nanometer process facilities." In particular, two FPGA design companies will be using Intel's fabrication plant, and "the unit has more than two customers but others are not disclosing their plans yet."
kodiaktau writes "Google is working to deliver a heads-up display allowing users access to email, maps and other tools through a wearable interface. According to the NY Times' sources, the device will be available later this year, and sell for prices comparable to smartphones. 'The people familiar with the Google glasses said they would be Android-based, and will include a small screen that will sit a few inches from someone’s eye. They will also have a 3G or 4G data connection and a number of sensors including motion and GPS. ... The glasses will have a low-resolution built-in camera that will be able to monitor the world in real time and overlay information about locations, surrounding buildings and friends who might be nearby, according to the Google employees. The glasses are not designed to be worn constantly — although Google expects some of the nerdiest users will wear them a lot — but will be more like smartphones, used when needed.'"
dcblogs writes "The European Commission last week said it is doubling its multi-year investment in the push for exascale computing from €630 million to €1.2 billion (or the equivalent of $1.58 billion). They are making this a priority even as austerity measures are imposed to prevent defaults. China, meanwhile, has a five-year plan to deliver exascale computing between 2016-20 (PDF). The Europeans announced the plan the same week the White House released its fiscal year 2013 budget, which envisions a third year of anemic funding to develop exascale technologies. Last year, the U.S. Department of Energy science budget asked for nearly $91 million in funding for the efforts in the current fiscal year; it received $73.4 million. DOE science is trying for about $90 million for exascale for 2013. There's more funding tucked in military and security budgets. The U.S. wants exascale around 2018, but it has yet to deliver a plan or the money for it."
snydeq writes "Deep End's Paul Venezia sees few business IT situations that could make good use of full cloud storage services, outside of startups. 'As IT continues in a zigzag path of figuring out what to do with this "cloud" stuff, it seems that some companies are getting ahead of themselves. In particular, the concept of outsourcing storage to a cloud provider puzzles me. I can see some benefits in other cloud services (though I still find the trust aspect difficult to reconcile), but full-on cloud storage offerings don't make sense outside of some rare circumstances.'"
