kgeiger writes "In the Feb. 2011 issue of IEEE Spectrum online, Peter Kogge, an IEEE Fellow and professor of computer science and engineering at the University of Notre Dame, outlines why we won't see exaflops computers soon. To start with, consuming 67 MW (an optimistic estimate) is going to make a lot of heat. He concludes, 'So don't expect to see a supercomputer capable of a quintillion operations per second appear anytime soon. But don't give up hope, either. [...] As long as the problem at hand can be split up into separate parts that can be solved independently, a colossal amount of computing power could be assembled similar to how cloud computing works now. Such a strategy could allow a virtual exaflops supercomputer to emerge. It wouldn't be what DARPA asked for in 2007, but for some tasks, it could serve just fine.'"

An anonymous reader writes "30 years before words like performance capture, augmented reality, or avatars were around — let alone commonplace — experimental film and video artist Tom DeWitt created a system that features aspects of all of them. Pantomation let users interact in real-time with a digital environment and props. It was built using Apple IIe's, analog video gear, and lots of custom hacking and patching. He's currently working on a holographic 3D system that's similarly ahead of its time."

crookedvulture writes "Nvidia has uncorked another mid-range graphics card, the GeForce GTX 560 Ti. Every tech site on the web seems to have coverage of this new $250 offering, and The Tech Report's review will tell you all you need to know about the various flavors available, including how their performance compares to cards from 2-3 years ago. Interestingly, the review concludes that pretty much any modern mid-range graphics card offers smooth frame rates while playing the latest games at the common desktop resolution of 1920x1080. You may want to pay closer attention to power consumption and noise levels when selecting a new card."

siliconbits writes "A single 'universal' memory technology that combines the speed of DRAM with the non-volatility and density of flash memory was recently invented at North Carolina State University, according to researchers. The new memory technology, which uses a double floating-gate field-effect-transistor, should enable computers to power down memories not currently being accessed, drastically cutting the energy consumed by computers of all types, from mobile and desktop computers to server farms and data centers, the researchers say."

Haffner quotes physorg which says "Italian scientists Andrea Rossi and Sergio Focardi of the University of Bologna announced that they developed a cold fusion device capable of producing 12,400 W of heat power with an input of just 400 W....when the atomic nuclei of nickel and hydrogen are fused in their reactor, the reaction produces copper and a large amount of energy. The reactor uses less than 1 gram of hydrogen and starts with about 1,000 W of electricity, which is reduced to 400 W after a few minutes. Every minute, the reaction can convert 292 grams of 20C water into dry steam at about 101C. Since raising the temperature of water by 80C and converting it to steam requires about 12,400 W of power, the experiment provides a power gain of 12,400/400 = 31."

Blacklaw writes "A team of researchers comprised of members from the Semiconductor Research Corporation and Stanford University has developed a new thermal nanotape which it claims will lead to chips that run cooler and last longer. The thermal nanotape, constructed of binder materials surrounding carbon nanotubes, promises to lead to the creation of semiconductors — including CPUs and GPUs — that don't suffer from the rigors of frequent temperature changes, known as thermal cycling."

storagedude writes "Although it may have gone unnoticed by most IT industry watchers, this week's announcement from Microsoft and HP that the two have combined on integrated appliances for corporate business intelligence and email could be the start of a closer relationship between the two IT giants as they seek to counteract the growing hardware and software dominance of IBM and Oracle. From the article: 'Combine Microsoft and HP — call it MicroHP — and what do you have? A full Windows-plus-Linux scale-out hardware and software lineup, with an exceptionally strong position both in SaaS/public cloud and data centers, and a huge presence on the business desktop. This would allow such a combined entity to produce well-tuned appliances for such hot areas as BI/analytics — as Microsoft and HP have just done.'"

Saysys sends an excerpt from a story at the Globe and Mail: "In September, a privately held and highly secretive US biotech company named Joule Unlimited received a patent for 'a proprietary organism' – a genetically engineered cyanobacterium that produces liquid hydrocarbons: diesel fuel, jet fuel and gasoline. This breakthrough technology, the company says, will deliver renewable supplies of liquid fossil fuel almost anywhere on Earth, in essentially unlimited quantity and at an energy-cost equivalent of $30 (US) a barrel of crude oil. It will deliver, the company says, 'fossil fuels on demand.' ... Joule says it now has 'a library' of fossil-fuel organisms at work in its Massachusetts labs, each engineered to produce a different fuel. It has 'proven the process,' has produced ethanol (for example) at a rate equivalent to 10,000 US gallons an acre a year. It anticipates that this yield could hit 25,000 gallons an acre a year when scaled for commercial production, equivalent to roughly 800 barrels of crude an acre a year."

An anonymous reader writes with word from Australia that "There's a new world record for the fastest solar-powered land vehicle: 88 km/h average speed over one kilometre in a lightweight car that uses about the same power as a toaster." As the article goes on to explain, this solar racer, built last year by students from the University of New South Wales, managed to nab that speed record earlier this month on an Australian navy base airstrip.

astrodoom writes "AppleInsider has posted a story detailing a new patent application by Apple that hints at the possibility of adding a touchscreen to the company's magic mouse. At a basic level this could mean things like customizable colors or artwork displayed on the user's mouse, but the possibilities extend much further to fully customizable mouse layouts and program controls. Apple Insider comments on the possibilities: 'The display on the mouse would change according to what the user may be doing on their Mac. As an example, the application describes displaying a number of icons for quickly selectable options when a user is running Apple's Pages word processing application. Switching over to the spreadsheet software, Numbers would reconfigure the buttons on the screen to allow for commands in that respective application.'"

rsk points out this "review of the $1200 Makerbot Thing-o-Matic 3D printer. After a 16-hour self-assembly and a few weeks of use, a blown PSU was replaced with a higher powered PSU via a mod to the Thing-o-Matic. Video of the Thing-o-Matic printing out little solar panel mounts from Google Sketch-up included in the review. Final thoughts suggest that the Thing-o-Matic is not a great gift for non-engineers: 'You need a decent understanding of robotics, hardware, software, electronics and mechanics, need a little hand dexterity and a ton of patience.'"

arcticstoat writes "IBM has revealed that graphene can't fully replace silicon inside CPUs, as a graphene transistor can't actually be completely switched off. In an interview, Yu-Ming Lin from IBM Research (Nanometer Scale Science and Technology) explained that 'graphene as it is will not replace the role of silicon in the digital computing regime.' Last year, IBM demonstrated a graphene transistor running at 100GHz, while researchers at UCLA produced a graphene transistor with a cut-off frequency of 300GHz, prompting predictions of silicon marching towards its demise, making way for a graphene-based future with 1THz CPUs. However, Lin says, 'there is an important distinction between the graphene transistors that we demonstrated and the transistors used in a CPU. Unlike silicon, graphene does not have an energy gap, and therefore, graphene cannot be "switched off," resulting in a small on/off ratio.' That said, Lin also pointed out that graphene 'may complement silicon in the form of a hybrid circuit to enrich the functionality of computer chips.' He gives the example of RF circuits, which aren't dependent on a large on/off ratio."

Pickens writes "Network World reports that in the past if you wanted to remove the outer case on your iPhone 4 to replace the battery or a broken screen, you could use a Phillips screwdriver to remove two tiny screws at the base of the phone and then simply slide off the back cover. But now Apple is replacing the outer screw with a mysterious tamper-resistant 'pentalobular' screw across its most popular product lines, making it harder for do-it-yourselfers to make repairs. What about existing products in the field? Pentalobular screws might find their way into them, too. 'Apple's latest policy will make your blood boil,' says Kyle Wiens, CEO of iFixit. 'If you take your iPhone 4 into Apple for any kind of service, they will sabotage it by replacing your Phillips screws with the new, tamper-resistant screws. We've spoken with the Apple Store geniuses tasked with carrying out this policy, and they are ashamed of the practice.' Of course, only Apple-authorized service technicians have Pentalobular screwdrivers and they're not allowed to resell them. 'Apple sees a huge profit potential,' says Wiens. 'A hundred dollars per year in incremental revenue on their installed base is a tremendous opportunity.'"

nicomede writes "The French state-owned DCNS (French military shipyard) announced today a concept study for an underwater nuclear reactor dedicated to power coastal communities in remote places. It is derived from nuclear submarine power plants, and its generator would be able to produce between 50 MWe and 250MWe. Such a plant would be fabricated and maintained in France, and dispatched for the different customers, thus reducing the risk for proliferation."

mxhf writes "I just came back from a four-week vacation to Mexico. This is the country for Aztecs and Maya Ruins and we visited plenty of them. Needless to say we took thousands of pictures with two cameras. Having arrived back home I realize that my hard-disk does not have enough space left to hold the additional 16GB that I collected on the other side of the globe. Now, my hard disk already is 250GB. I work exclusively on a laptop and do not want to change this. I know that there are larger disks today. But I figured that the time has come to finally move my image collection from my laptop to somewhere else. But where should I go? So, how do you store your photo collections? And how do you keep backups? These are obviously images that I want to keep for my life. So the need to survive fires, burglaries, etc. I think the amount of data I have rules online storage out. Should I just get two USB disks and leave one at a reasonably save location? I think this must be a common problem today. And yes — before you ask — I do know that the first thing to do is to go through your collection and dump what is not worth keeping."

eldavojohn writes "A new reactor developed by CalTech shows promise for producing renewable fuel from sunlight. The reactor hinges on a metal oxide named Ceria that has very interesting properties at very high temperatures. It exhales oxygen at very high temperatures and inhales oxygen at very low temperatures. From the article, 'Specifically, the inhaled oxygen is stripped off of carbon dioxide (CO2) and/or water (H2O) gas molecules that are pumped into the reactor, producing carbon monoxide (CO) and/or hydrogen gas (H2). H2 can be used to fuel hydrogen fuel cells; CO, combined with H2, can be used to create synthetic gas, or "syngas," which is the precursor to liquid hydrocarbon fuels. Adding other catalysts to the gas mixture, meanwhile, produces methane. And once the ceria is oxygenated to full capacity, it can be heated back up again, and the cycle can begin anew.' The only other piece of the puzzle is a large sunlight concentrator to raise the temperature to the necessary 3,000 degrees Fahrenheit. The team is working on modifying and refining the reactor to require a lower temperature to achieve the two-step thermochemical cycle. Another issue is the heat loss which the team claims could be reduced to improve efficiency to 15% or higher. Since CO2 is an input, the possibility exists for coal and power plants to collect CO2 emissions to be used in this process which would effectively allow us to "use the carbon twice." Another idea listed is that a "zero CO2 emissions" is developed along these lines: 'H2O and CO2 would be converted to methane, would fuel electricity-producing power plants that generate more CO2 and H2O, to keep the process going.' The team's work was published last month in Science."

cylonlover writes "Following on from a successful maiden flight under battery power in 2010, AeroVironment's high altitude, long endurance (HALE) Global Observer unmanned aircraft has now taken to the skies using hydrogen-fueled propulsion. The aircraft reached an altitude of 5,000 feet during the four hour flight on January 11 at Edwards Air Force Base (EAFB) in California. Both the endurance and the altitude of the system will be expanded in further test flights in order to achieve the planned operational altitude of 55,000 to 65,000 feet."

Orome1 writes "In the last couple of decades, we have become so accustomed to the idea that the public portion of our everyday life is watched and recorded — in stores, on the street, in institutions — that we often don't even notice the cameras anymore. Analog surveillance systems were difficult to hack into by people who lacked the adequate knowledge, but IP cameras — having their own IPs — can be quite easily physically located and their stream watched in real-time by anyone who has a modicum of computer knowledge and knows what to search for on Google."

hype7 writes "The Harvard Business Review is running a very interesting article on how this year's CES marked the end of the Wintel platform's dominance. Their argument is that tablets are going to disrupt the PC, and these tablets are predominantly going to be running on Google's Android powered by ARM processors — 'Armdroid.' Quoting: 'Both Microsoft and Intel have suffered from the same problem that most successful companies face when dealing with disruption. They cannot find a way to profitably invest in low-end offerings. Think about it from Microsoft's point of view: now that Windows 7 has been developed, to sell another copy, they don't have to do a single thing. Because of this, it becomes very hard for any executive to advocate the complete development of a low cost OS that will run on tablets: not only would it cost Microsoft a lot to develop, but it would result in cannibalization of its core product sales. Intel has the exact same issue. Why focus on Atom, or an even lower-end chip, when there is so much more margin to be made by focusing on its multi-core desktop processors?'"

TechieAlizay points out a post at Geekword.net about a man who hacked Microsoft's Kinect to play Max Payne. "This hack was possible due to FAAST (a toolkit for Kinect), OpenNi/Nite and GlovePIE. Here's how the hacker describes the different control gestures: 'As you can see, the leaning left and right stuff is all there – and moving your body forward and back moves you back and forward. The reload and interact gestures are becoming pretty standard for me now, and pain killers are popped with an upward motion of the left hand. What makes this special though is the leg movements that activate bullet time. The result is bullet time diving for real! When this game hit just after the Matrix film came out, it caused a big stir – with Kinect augmentation it gets even better. The one thing that needs fixing is weapon select; this will be handled by the +/- buttons on the mote in future, I think.'" Another video shows Kinect controlling Left 4 Dead 2. In addition to future PC support, Microsoft is reportedly working on an official SDK. Yet another recent hack of note allows a human to control a humanoid robot with an impressive level of accuracy. Just be careful if you play the Kinect boxing game; somebody might call the police.
