An anonymous reader writes "Last year tomography researchers of the ASTRA group at the University of Antwerp developed a desktop supercomputer with four NVIDIA GeForce 9800 GX2 graphics cards. The performance of the FASTRA GPGPU system was amazing; it was slightly faster than the university's 512-core supercomputer and cost less than 4000EUR. Today the researchers announce FASTRA II, a new 6000EUR GPGPU computing beast with six dual-GPU NVIDIA GeForce GTX 295 graphics cards and one GeForce GTX 275. The development of the new system was more complicated and there are still some stability issues, but tests reveal the 13 GPUs deliver 3.75x more performance than the old system. For the tomography reconstruction calculations these researchers need to do, the compact FASTRA II is four times faster than the university's supercomputer cluster, while being roughly 300 times more energy efficient."

At about $40 per unit, the controller is much cheaper than specialized sensors. The scientists are still considering how to add storage and extend the battery life."

Hugh Pickens writes "BBC reports that Markus Haering's company had been working with the authorities in Basel, Switzerland to try to convert the heat in deep-seated rocks into electricity, but the project was suspended in 2006 when drilling triggered earthquakes, one of them with a magnitude of 3.4, leading Haering's company to pay out $9M in damages. Haering's team planned to drill a series of holes penetrating up to 3 miles (4.8 km) underground with water being pumped onto rocks with a temperature of more than 195C. Basel's location on top of a fault line – the upper Rhine trench – had been deliberately chosen because the heat was closer to the Earth's surface. A risk assessment has since shown that the prospect of further quakes is too high to continue drilling in the city. Haering faces up to five years in prison if the judge finds he intentionally damaged property. Haering has admitted the 3.4 magnitude earthquake was stronger than he had expected and that his team 'had very little knowledge of seismicity' before starting to drill, but called the quakes 'a learning process for everyone involved.' Despite Haering's trial, the Swiss appetite for geothermal projects has not diminished. Engineers are beginning preliminary drilling in Zurich to see whether that area was suitable for a similar scheme, and St. Gallen, in eastern Switzerland, plans to start work on its own geothermal project next year. Drilling efforts are being closely watched in the US, where the energy department is sponsoring more than 120 geothermal energy projects in several states."

StonyCreekBare writes "I am wondering what slashdotters have to offer on the idea of Linux based security systems, especially DVR software. I am aware of Zoneminder, but wonder what else is out there? Are there applications that will not only monitor video cameras, but motion sensors and contact closure alarms? What is state of the art in this area, and how do the various Linux platforms stack up in comparison to dedicated embedded solutions? Will these 'play nice' with other software, such as Asterisk, and Misterhouse? Can one server host three or four services applications of this nature, assuming CPU/memory/disk resources are sufficient?"

Barence writes "PC Pro's contributing editor Paul Ockendon has bought a new lawnmower powered by lithium-ion batteries — part of a recent flood of such lithium-ion-powered garden and workshop tools which are taking over from NiCd and NiMH thanks to lighter weight, longer life and lack of the pernicious 'memory effect.' This is pretty much the same battery technology used in laptops, mobile phones and MP3 players, so volume manufacture is already established. Yet laptop manufacturers charge more per Watt-hour than lawnmower makers. This blog investigates whether such a seemingly ludicrous situation can be justified."

Hugh Pickens writes "Consumer Reports says that most of the time, extended service contracts aren't worth the additional dollars. But the Washington Post reports that purchases of extended warranties are up 10 percent over last year, according to the Service Contract Industry Council, a trade group. Consumers 'tend to be more risk-averse and are less willing to absorb the cost of an unexpected product repair or replacement,' says Timothy Meenan, the council's executive director. Mark Kotkin, director of survey research for CR, acknowledges that there are instances when the extended warranty can be worth it. 'We recommend getting one for the Apple computer,' Kotkin says. 'The tech support that comes with the extended warranty is great. Without it, the tech support is skimpy.' Another product where extended warranties may be of use are giant television sets, where few manufacturers will come to your home to make warranty repairs. Extended service contracts for big screen TVs often offer in-home repair, says Meenan, who once shipped a Sony TV to the service center for repair under the manufacturer's warranty. 'They fixed it and brought it back 45 days later.'"

garg0yle writes "A team has managed to open the Barnes and Noble Nook e-reader, gaining full access to the operating system. From the article: 'The Nook is now a computer running a full Android operating system, with a built-in, free cellular connection to the internet. It also has a battery that lasts days, not hours.' They are documenting their progress on the Nook Devs wiki."

newscloud writes "Tech writer Glenn Fleishman compares the arguments against affordable, high speed, broadband Internet access in each home to arguments made against providing for common access to electricity in 1900 e.g. '...electric light is not a necessity for every member of the community. It is not the business of any one to see that I use electricity, or gas, or oil in my house, or even that I use any form of artificial light at all.' Says Fleishman, 'Electricity should go to people who had money, not hooked up willy-nilly to everyone ... Like electricity, the notion of whether broadband is an inherent right and necessity of every citizen is up for grabs in the US. Sweden and Finland have already answered the question: It's a birthright.'"

azoblue writes "Daniel Reetz did not want to lug around heavy textbooks, so he built a book scanner to create digital copies. '... over three days, and for about $300, he lashed together two lights, two Canon Powershot A590 cameras, a few pieces of acrylic and some chunks of wood to create a book scanner that's fast enough to scan a 400-page book in about 20 minutes (PDF). To use it, he simply loads in a book and presses a button, then turns the page and presses the button again. Each press of the button captures two pages, and when he's done, software on Reetz's computer converts the book into a PDF file. The Reetz DIY book scanner isn't automated — you still need to stand by it to turn the pages. But it's fast and inexpensive.'"

A story at the BBC notes increasing pressure from the European Commission to set standards that would limit the maximum volume on portable MP3 players. Their reasoning is that it would protect users from damaging their hearing after listening to loud music for extended periods. Quoting: "This follows a report last year warning that up to 10m people in the EU face permanent hearing loss from listening to loud music for prolonged periods. EU experts want the default maximum setting to be 85 decibels, according to BBC One's Politics Show. Users would be able to override this setting to reach a top limit of 100 decibels. ... Some personal players examined in testing facilities have been found to reach 120 decibels, the equivalent of a jet taking off, and no safety default level currently applies, although manufacturers are obliged to print information about risks in the instruction manuals. Modern personal players are seen as more dangerous than stationary players or old-fashioned cassette or disk players because they can store hours of music and are often listened to while in traffic with the volume very high to drown out outside noise."

ptorrone writes "MAKE's yearly open source hardware guide is now online with over 125 projects in 19 categories. The creators of all of these projects have decided to publish completely all the source, schematics, firmware, software, bill of materials, parts list, drawings, and 'board' files to recreate the hardware. They also allow any use, including commercial. In other words, you can make a business making and selling any of these objects. This is similar to open source software like Linux, but hardware-centric."

jangel writes "Stanford University researchers have demonstrated a way to turn ordinary paper into a battery, which may be crumpled or pressed into any form. It's said the technology promises greater durability, higher efficiency, and faster energy transfer than traditional batteries. The technique uses special ink made of carbon nanotubes and silver nanowires. Thanks to the small diameters of these materials, the ink sticks strongly to the fibrous paper, allowing the battery to be extremely durable. The paper battery could last through 40,000 charge-discharge cycles — at least an order of magnitude more than lithium batteries. According to the researchers, the paper batteries will be low-cost, may be crumpled or folded, and can even be soaked in acidic or basic solutions, yet their performance does not degrade. 'We just haven't tested what happens when you burn it,' one of the researchers quipped." This is the same Stanford research team, lead by Yi Cui, whose work with nanotechnology for battery applications we have discussed before. We've also delved into alternate routes to the holy grail of the ultra-thin battery.

eldavojohn writes "Six companies have pleaded guilty to worldwide price fixing of Thin-Film Transistor Liquid Crystal Displays from Sept. 14, 2001, to Dec. 1, 2006. For violating the Sherman Act, the companies have agreed to pay criminal fines of over $860 Million. In addition, nine executives have been charged in the scandal. The pricing scam affected some of the largest companies at the time, including Apple, HP and Dell. (If you bought a TFT-LCD from them in that time frame, you may be one of the victimized consumers.) From the DOJ release, 'According to the charge, Chi Mei carried out the conspiracy by agreeing during meetings, conversations and communications to charge prices of TFT-LCD panels at certain pre-determined levels and issuing price quotations in accordance with the agreements reached. As a part of the conspiracy, Chi Mei exchanged information on sales of TFT-LCD panels for the purpose of monitoring and enforcing adherence to the agreed-upon prices.'"

An anonymous reader writes "Researchers at the University of Tokyo, led by electrical engineering professor Takao Someya, have created a new kind of low-cost, plastic, flash memory storage device. Although not as dense or stable as its silicon cousin, the plastic flash memory is useful because of its low cost, simple manufacturing process, and potential use in e-paper or other flexible devices. To demonstrate the memory, Someya's group integrated a 676-memory-cell device with a rubber pressure sensor. The flexible sensor-memory device, which is less than 700 micrometers thick, can record pressure patterns and retain them for up to a day."

itwbennett writes "Not normally 'one to enjoy a casual read of a lawsuit,' blogger Peter Smith admits to finding the suit Michael Arrington is filing against Fusion Garage over the JooJoo (nee CrunchPad) fascinating. 'Skip to page 4, starting with item 11,' says Smith. 'At this point I don't know what to think, Every time I get close to pretty much accepting Arrington's story at face value, he pulls something that makes me stop and reexamine his arguments.' For example, says Smith, in one bullet point in Arrington's latest salvo, he calls out the press, saying 'it is irresponsible for press to link to the pre-sale site.' 'This attempt to directly sway the press away from Fusion Garage really spikes my suspicion meter' says Smith. 'After all, Arrington is the press. If I started writing screeds advising him on what he should or should not say about a product, what would he think?'"

xbeefsupreme writes "Frederick and Gerrit Braun of Hamburg, Germany began working on 'Miniatur Wonderland,' a massive model train set, in 2000. Although it is not complete yet, it covers 12,380 square feet of space, has six miles of track and so far has six sections representing different countries. Landmarks within the set include Mount Rushmore, the Matterhorn in Switzerland, and a 4-foot-long passenger ship floating in a miniature Scandinavian fjord."

An anonymous reader writes "The long-time Linux kernel module for block replication over TCP, DRBD, has been accepted as part of the main Linux kernel. Amid much fanfare and some slight controversy, Linus has pulled the DRBD source into the 2.6.33 tree, expected to release February, 2010. DRBD has existed as open source and been available in major distros for 10 years, but lived outside the main kernel tree in the hands of LINBIT, based in Vienna. Being accepted into the main kernel tree means better cooperation and wider user accessibility to HA data replication."

1sockchuck writes "A supercomputing center in Quebec has transformed a huge concrete silo into the CLUMEQ Colossus, a data center filled with HPC clusters. The silo, which is 65 feet high with two-foot thick concrete walls, previously housed a Van de Graaf accelerator dating to the 1960s. It was redesigned to house three floors of server cabinets, arranged so cold air can flow from the outside of the facility through the racks and return via an interior 'hot core.' The construction and operation of the unique facility (PDF) are detailed in a presentation from CLUMEQ."

MikeChino writes "Researchers at Arizona State University have genetically engineered cyanobacteria to dissolve from the inside out, making it easy to access the high-energy fats and biofuel byproducts located within. To do this they combined the bacteria's genes with genes from the bacteriaphage — a so-called 'mortal enemy' of bacteria that cause it to explode. Cyanobacteria have a higher yield potential than most biofuels currently being used, and this new strain eliminates the need for costly and energy intensive processing steps."

dcblogs writes "IBM has released a new mainframe server that doesn't include its z/OS operating system. This Enterprise Linux Server line supports Red Hat or Suse. The system is packaged with mainframe management and virtualization tools. The minimum processor configuration uses two specialty mainframe processors designed for Linux. IBM wants to go after large multicore x86 Linux servers and believes the $212,000 entry price can do it."
