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.'"
jpwilliams writes "This tiny projector can use any surface you have on hand to project an image. Using a webcam, it adapts to the surface, not just by adjusting keystone, but also following that surface and displaying different amounts of information (in certain cases). The guy in the video also uses a coffee mug as an app changer."
Zothecula writes "If you thought WikiLeaks was a disruptive idea, the transparency grenade is going to blow you away. This tiny bit of hardware hidden under the shell shaped like a classic Soviet F1 hand grenade allows you to leak information from anywhere just by pulling a pin. The device is essentially a small computer with a powerful wireless antenna and a microphone. Following 'detonation,' the grenade intercepts local network traffic and captures audio data, then makes the information immediately available online."
Metrix Create:Space is full of people busily making electronic gadgets. And shot glasses. And everything in between. Some of them saw the street-level sign and stopped in out of curiosity, while others are long-time createspace scenesters. It doesn't matter which you are, says Metrix founder Matt Westervelt. Come in and make something. Need new skills? They have workshops. And lots of great tools.
CUPS is the popular open-source printing system that many projects have used successfully as a core, for desktop printing and as the basis of dedicated print servers. Reader donadony writes with word that Apple "has chosen to abandon certain Linux exclusive features, [while] continuing with popular Mac OS X features. The changeover is being attempted by Apple to set new printing standards that will not require 'drivers' in the future." However, as this message from Tim Waugh at Red Hat points out, all is not lost: "Where they are of use for the Linux environment, those orphaned features will continue to be maintained at OpenPrinting as a separate project."
someWebGeek writes "From PhysOrg's 'Taking biofuel from forest to highway,' University of British Columbia biofuel expert Jack Saddler says, 'we will become less dependent on fossil fuels and will become more dependent on fuels made from the sugars and chemicals found in plants.' Nothing too new there; the idea of biofuels eventually taking over from petroleum distillates has been around for ages. However, Saddler contends further that 'Similar to an oil refinery that processes crude oil to make thousands of supplementary products like plastics, dyes, paints, etc., the biorefinery would use leftover agricultural and forest material to make many of the same products, but from a sustainable and renewable resource.' I remember my organic chem instructor back in '81 telling us that eventually the textbooks would have to be rewritten. There would be no presumption of fractional distillation of thousands of basic compounds from petroleum, and the teaching emphasis would shift to synthesis from simple hydrocarbons. He noted that we'd all miss 'the good, ole days' when synthetic fibers, plastics, etc. were cheap... or even an economically viable option. I can live without rayon, but, dang, I'm gonna miss polyvinyl chloride!"
Zothecula writes "Oxford Nanopore has been developing a disruptive nanopore-based technology for sequencing DNA, RNA, proteins, and other long-chain molecules since its birth in 2005. The company has just announced that within the next 6-9 months it will bring to market a fast, portable, and disposable protein sequencer that will democratize sequencing by eliminating large capital costs associated with equipment required to enter the field."
redletterdave writes "Samsung Electronics announced Monday that it will spin off its LCD business division to launch a new entity, provisionally called Samsung Display Co., set to go live on April 1, 2012. The new business will launch with about $668 million in capital, but Samsung plans to invest about $5.8 billion in 2012 to develop better displays. The move, which now awaits shareholder approval, has been rumored for months since Samsung's LCD business announced operating losses of $666 million in 2011, citing sluggish TV sales. The company's spin-off display business may eventually merge with Samsung Mobile Display, which makes the company's organic light-emitting diode (OLED) panels that are currently in high demand."
angry tapir writes "Intel's experimental solar-powered processor may have started off as a fun project, but the chip maker is now looking to extend the technology to hardware such as graphics processors, memory and floating point units. Intel last year showed the low-power processor — charged only by the light from a reading lamp — running Windows and Linux PCs. Intel is expected to share further details about the processor, which is code-named Claremont, at the International Solid-State Circuits Conference in San Francisco. The company is also expected to reveal information about efforts to integrate wireless capabilities into Atom chips for mobile devices."
Lucas123 writes "New research shows that far more than wireless network or CPUs, the NAND flash memory in cell phones, and in particular smartphones, affects the device's performance when it comes to loading apps, surfing the web and loading and reading documents. In tests with top-selling 16GB smartphones, NAND flash memory slowed mobile app performance from two to three times with one exception, Kingston's embedded memory card; that card slowed app performance 20X. At the bottom of the bottleneck is the fact that while network and CPUs speeds have kept pace with mobile app development, flash throughput hasn't. The researchers from Georgia Tech and NEC Corp. are working on methods to improve flash performance (PDF), including using a PRAM buffer to stage writes or be used as the final location for the SQLite databases."
Barence writes "In 2006, AMD could seemingly do no wrong. Its processors were the fastest in the PC market, annual revenue was up a record 91%, expansion into the graphics game had begun with the high-profile acquisition of ATI, and it was making exciting plans for a future where it looked like it could 'smash Intel's chip monopoly' for good. Now the company is fighting for its very survival. How did AMD end up surrendering such a advantageous position – and was it given an unfair shove on the way down? This article has plotted AMD's decline, including the botched processor launches, the anti-competitive attacks from Intel and years of boardroom unrest."
New submitter Dave_Minsky writes "The U.S. Secret Service responded to a FOIA request on Monday that reveals the names of the printer companies that cooperate with the government to identify and track potential counterfeiters. The Electronic Frontier Foundation revealed in 2005 that the U.S. Secret Service was in cahoots with selected laser printer companies to identify and track printer paper using tiny microscopic dots encoded into the paper. The tiny, yellow dots — less than a millimeter each — are printed in a pattern over each page and are only viewable with a blue light, a magnifying glass or a microscope. The pattern of dots is encodes identifiable information including printer model, and time and location where the document was printed." Easy enough to avoid government dots; just don't buy printers from Canon, Brother, Casio, HP, Konica, Minolta, Mita, Ricoh, Sharp, or Xerox.

Hints of the new display's resolution were found in iBooks 2, which contains hi-DPI versions of its artwork. The iPad 3 is rumored to be launching in early March."
First time accepted submitter core_tripper writes "Students at the University of Twente have stolen thirty laptops from various members of the university's staff. They were not prosecuted for this, so they could just get on with their studies. Indeed, these students even received ECTS credits for these thefts. UT researcher Trajce Dimkov asked the students to steal the machines as part of a scientific experiment. Stealing these laptops turned out to be a pretty simple matter."
MojoKid writes "OpenXC is an open source connectivity platform developed in tandem by Ford and open source hardware maker Bug Labs. Announced this fall, the platform is designed to allow developers the ability to use Android- and Arduino-based modules to interact with a vehicle's in-car tech, such as vehicle sensors and GPS units. The OpenXC website succinctly describes the platform as 'an API to your car.' Ford announced that OpenXC beta test kits are now shipping to developers worldwide, including U.S. institutions such as MIT and Standford as well as India's HCL Technologies."
