Full Immersion Cooling Comes To Desktop PCs

mr_sifter writes "After three years of research and around £100,000 of R&D costs, UK-based Armari has unveiled its XCP prototype. It's a full immersion liquid cooled PC which supports standard ATX components. Unlike conventional liquid cooled PCs, the components are all easy to swap in and out as they're swimming in liquid, rather than under waterblocks. It also looks amazing, pumping around 70KG of electrically inert cooling fluid (salvaged from an old Cray) around its military grade perspex shell."

Researchers offer new tool that finds additional clues of fraudulent Web sites

SAN FRANCISCO (AP) - Intercepting Internet traffic, and spying on the communication between two computers, is a gold mine for hackers. Now Carnegie Mellon University researchers hope software they've built will make it harder for criminals to hit that jackpot.

The Internet's Biggest Security Hole Revealed

At DEFCON, Tony Kapela and Alex Pilosov demonstrated a drastic weakness in the Internet's infrastructure that had long been rumored, but wasn't believed practical. They showed how to hijack BGP (the border gateway protocol) in order to eavesdrop on Net traffic in a way that wouldn't be simple to detect. Quoting: "'It's at least as big an issue as the DNS issue, if not bigger,' said Peiter 'Mudge' Zatko, noted computer security expert and former member of the L0pht hacking group, who testified to Congress in 1998 that he could bring down the internet in 30 minutes using a similar BGP attack, and disclosed privately to government agents how BGP could also be exploited to eavesdrop. 'I went around screaming my head about this about ten or twelve years ago.

"Shimmer Vision" Scopes See Better Using Heat

holy_calamity writes "New Scientist reports on a neat DARPA idea that uses the shimmer of heat haze to allow binoculars to see further. It works by exploiting the fact that some distortions from heat haze actually magnify objects behind them. The binoculars collect a series of frames when that is occurring to boost magnification by 3 times. The design goal is to be able to present one image a second, and to enable facial recognition at 90% accuracy at a distance of 1 km. The scopes could be on the battlefield inside of 3 years."

First Oort Cloud Object May Have Been Discovered

SpuriousLogic alerts us to the discovery of what may be the first object ever discovered from the inner edge of the Oort cloud. 2006 SQ372 was found on images from the Sloan Digital Sky Survey. Its discoverers theorize that this comet-like object and the planetoid Sedna, first spotted in 2003, might be Oort denizens. Sedna is in a stable orbit but 2006 SQ372 has been perturbed by the gravity of Uranus and/or Neptune, simulations suggest, so its orbital history is unknowable. 2006 SQ372 will travel out to 1,600 AU on this orbit, making it the most distant solar-system object yet found. The Oort cloud is believed to extend ten times that far, or about a quarter of a light-year. "Theoretical models of the formation of the Oort Cloud predict that it should also host a massive inner part, but comets from this region never make it near Earth.

What To Do With All of My Gadget Chargers?

Not a single pair of them share a similar connector. I have two power strips whose singular purpose is to energize these chargers. My question to Slashdot is: How do you organize all of your different chargers? Please, share your secrets."

Newegg Defies New York Sales Tax Law

JagsLive informs us that the electronics retailer Newegg.com is defying New York lawmakers; it has suddenly stopped collecting sales tax from New York online shoppers. The "Amazon tax," which went into effect June 1, requires online merchants to collect sales tax if they have any affiliates in the state. Amazon is complying but has sued the state on constitutional grounds. Overstock.com dropped all of its New York affiliates and then joined the Amazon lawsuit. Newegg started out complying with the law on June 1, but stopped collecting taxes for New York on August 21. From Newegg's letter to its customers: "After careful review and consideration, we are pleased to inform you that we have stopped collecting New York sales tax, effective August 21, 2008," reads an email the company tossed at customers late last week, including at least one l

Archrs - an everyday story of web development

The Archers is a radio soap opera - "an everyday story of country folk" - that has been running for more than 15,000 episodes since May 1950. What I find particularly intriguing about The Archers in terms of the future of radio is that it is, in a way, happening in real-time. Every evening on Radio 4 the programme contains events that happened (approximately) "today" in Ambridge - so if it's Easter in real-life then it's Easter in The Archers. It's also very topical - featuring real-life events such as outbreaks of foot-and-mouth disease or the World Cup. As a drama, each episode is split into distinct scenes - typically indicated by a fading to silence - a convention for audio drama because of its need for clear signposting. The other interesting aspect is the many distinct facets of each scene - which characters are involved, the time o

Computer Virus Aboard the ISS

chrb writes "BBC News is reporting that laptops taken to the International Space Station by NASA astronauts are infected with the Gammima.AG worm. The laptops have no net connection; officials suspect the worm may have been transferred via a USB flash drive owned by an astronaut. NASA have said this isn't the first time computer viruses had travelled into space."

IPhone Web Claims Draw Governmental Rebuke in UK

Wills writes "Apple has been running an iPhone ad saying 'all parts of the internet are on the iPhone', but it had to be withdrawn after Britain's Advertising Standards Authority ruled that it gave 'a misleading impression of the internet capabilities of the iPhone' because the iPhone cannot access Flash or Java – features that are essential to some websites. This raises an interesting issue of where do you draw the line between essential and non-essential features of websites. What should the web look like? Should government authorities be the ones making that decision?"

Nvidia Firmly Denies Plans To Build a CPU

Barence writes "A senior vice president of Nvidia has denied rumours that the company is planning an entry into the x86 CPU market. Speaking to PC Pro, Chris Malachowsky, another co-founder and senior vice president, was unequivocal. 'That's not our business,' he insisted. 'It's not our business to build a CPU. We're a visual computing company, and I think the reason we've survived the other 35 companies who were making graphics at the start is that we've stayed focused.' He also pointed out that such a move would expose the company to fierce competition. 'Are we likely to build a CPU and take out Intel?' he asked. 'I don't think so, given their thirty-year head start and billions and billions of dollars invested in it. I think staying focused is our best strategy.

Zero Day Threat

Ben Rothke writes "Zero Day Threat: the Shocking Truth of How Banks and Credit Bureaus Help Cyber Crooks Steal Your Money and Identity is an interesting and eye-opening look at how banks and credit card companies make ID theft and fraud rather elementary. But with all that, this book must be read in the larger context of how today's society deals with, and is often oblivious to, risk. When is comes to risk, American society tolerates tens of thousands of drunk-driving deaths, gives millions in federal tobacco subsidies, and is oblivious about near-epidemics such as heart disease, obesity, and diabetes. With all that, it is doubtful that the myriad horror stories Zero Day Threat details will persuade Congress or the other players to do anything to curtail the problem with identity theft and internet fraud.

Capturing 3D Surfaces Simply With a Flash Camera

MojoKid writes with this excerpt from Hot Hardware (linking to a video demonstration): "Creating 3D maps and worlds can be extremely labor intensive and time consuming. Also, the final result might not be all that accurate or realistic. A new technique developed by scientists at The University of Manchester's School of Computer Science and Dolby Canada, however, might make capturing depth and textures for 3D surfaces as simple as shooting two pictures with a digital camera — one with flash and one without. First an image of a surface is captured without flash. The problem is that the different colors of a surface also reflect light differently, making it difficult to determine if the brightness difference is a function of depth or color. By taking a second photo with flash, however, the accurate colors of all visible portions of the sur

Gaining RAM For Free, Through Software

wakaramon writes with a piece from IEEE Spectrum about an experimental approach to squeezing more usable storage out of a device's existing RAM; the researchers were using a Linux-based PDA as their testbed, and claim that their software "effectively gives an embedded system more than twice the memory it had originally — essentially for free." "Although the price of RAM has plummeted fast, the need for memory has expanded faster still. But if you could use data-compression software to control the way embedded systems store information in RAM, and do it in a way that didn't sap performance appreciably, the payoff would be enormous."

Corporate Gaming Is Good For Business

The Economist is running a story about how gaming is on the rise in corporate environments, and how games are also becoming a popular tool for advertising. From internally developed games to commercial offerings to simply creating a framework in which employees can interact, game-based competitions and community building are leading to increased productivity, even for Fortune 500 companies. Quoting: "Take Microsoft's own experience. Before it releases a new version of its Windows operating system, it asks staff to help debug the software by installing and running the system. In the past, project managers had to spend a great deal of time and effort persuading busy Microsoftees to help them with this boring task. So for Windows Vista, the system's latest incarnation, Microsoft created a game that awarded points for bug-testing and prizes s

Mozilla Labs' "Ubiquity" Helps Automate Web Interactions

Martin writes "Mozilla Labs have released a prototype version of the Firefox add-on Ubiquity. It is basically Launchy (the application launcher) for Firefox with the difference that Ubiquity makes use of web APIs and the Firefox browser. The official website contains examples, a command list, information about creating your own commands and of course the Ubiquity extension that is compatible with Firefox 3.x. Ubiquity can pull and send data to various services like Twitter, display, find and embed Google Maps, perform searches, write emails, add entries to the calendar, digg stories and more."

Fuel-Cell Car Racing Series Aims To Spur Green Motoring

Anonymous Cow writes "The world's first international fuel-cell powered motor racing series kicked off in Rotterdam over the weekend. The organisers hope that 'Formula Zero,' like Formula 1, can become a forum for competing technology as much as anything else, helping green consumer cars to become better."

California's Wireless Road Tolls Easily Hackable

An anonymous reader writes "Nate Lawson, a researcher at RootLabs, has found a way to clone the wireless transponders used by the Bay Area FasTrak road toll system. This means you can copy the ID of another driver onto your own device and, as a result, travel for free while others foot the bill. Lawson also raises the interesting point of using the FasTrak system to create false alibis, by overwriting one's own ID onto another driver's device before committing a crime. Luckily, Lawson wasn't sued before he could reveal his research, unlike those pesky MIT students."

Google Drops Bluetooth API From Android 1.0

Ian Lamont writes "Google has dropped Bluetooth and the GTalkService instant messaging APIs from the set of tools for Android 1.0, but says that handsets using the Android OS will work with other Bluetooth devices such as headsets. According to a post on the official Android developer blog, Google dropped the Bluetooth API from the mobile OS because 'we plain ran out of time.' The GTalkService API was removed because of security concerns that included the possibility of applications revealing more details about users than they might want to let out, such as their real names and e-mail addresses."

New Evidence Debunks "Stupid" Neanderthal

ThinkComp writes "In what could possibly be a major blow to a scientific consensus that has held for decades, recent research suggests that the traditional conception of Neanderthals being "stupider" than Homo sapiens may in fact be misleading. As articles about the research findings state, 'early stone tool technologies developed by our species, Homo sapiens, were no more efficient than those used by Neanderthals.' The data used in the study is available on-line along with a visual description of the process used."

Gamepark Holdings Officially Announces the WIZ Handheld

Croakyvoice writes "Gamepark Holdings, the makers of the GP2X Console, have today announced the successor, which is called the WIZ. The new GBA Micro-sized console features a touchscreen, Linux OS, an Arm9 533MHZ 3D processor with 64MB of ram and will have commercial games on sale at launch in October. Best of all for fans of homebrew and emulation on the GP2X, all that needs to be done is recompiling of sourcecode."

Web Fraud 2.0 — Point-and-Click Cracking Tools

An anonymous reader writes "The Washington Post's Security Fix blog is running a fascinating series that peers inside some of the Web-based services cyber crooks are using to ply their trade: from masking their identity, to defeating CAPTCHAs, to creating counterfeit documents and validating stolen credit and debit cards. Everyone familiar with this space hears about these kinds of tools and services all the time in the abstract, but the Post blog includes screen shots and background details on the popularity of the services and how each one is helping to bring cyber crime that much closer to the realm of even the most newbie scam artists." Many of these tools require a working knowledge of Russian. Wouldn't surprise me to learn that Chinese-language tools exist too.

Scientists Discover Cows Point North

Dr Sabine Begall and colleagues from the University of Duisburg-Essen have discovered that cows tend to point north. The researchers studied deer in the Czech Republic and looked at thousands of images of cattle on Google Earth. The animals tended to face north when eating or resting. "We conclude that the magnetic field is the only common and most likely factor responsible for the observed alignment," the scientists wrote in an article. I guess cows will become the must-have item for long-distance hikers now. Having an edible compass would come in handy if you get lost.

Examining Portal's Teleportation Code

Gamasutra is running a story deconstructing the mechanics of Portal's teleportation programming. They present a snippet of Portal's code and a downloadable demo. They ran another article in this series earlier this year with an analysis Mario Galaxy's unique take on physics. We've discussed the development of Portal in the past. "Teleport mechanics in video games are nothing new. Puzzles from the original Gauntlet were memorable -- and more than likely, that wasn't the first game to use teleportation as a gameplay mechanic. The difference between Portal and all those that came before it is that Portal's teleportation acts as a frictionless tube between point A and point B. Physics are still hard at work inside the frictionless tube. Instead of simply repositioning an object from point A to point B, the player enters point A with full velo
