Vigile writes "Back in May, when the Isaiah architecture was first disclosed, VIA declared a performance victory over Intel's upcoming Silverthorne technology. Since then, Isaiah has become the VIA Nano processor, and Silverthorne changed to the Intel Atom — and now we can finally see tests comparing the two technologies. The Nano's out-of-order super-scalar design is definitely an architectural leap over the Atom's in-order single-issue design, but with Intel including HyperThreading technology in their CPU the competition is closer than expected. The Nano does win the performance tests by a considerable margin, but what might be more impressive is seeing the Atom use only 4 watts of power under full load!" As reader Mierdaan points out, that's 4 watts more than at idle, for about 60 watts total.

Ant writes with a story from Dan's Data, which says that the battery meter and connection-strength displays in your portable electronics are lying to you, "and not just when they whisper to you in the night." Quoting: "Mobile phones, and most modern laptops, have signal strength and battery life displays. One or both of these displays has probably been the focus of all of your attention at one time or another. Neither display is actually telling you what you think it's telling you. The signal strength bars on a mobile phone or laptop do, at least, say something about how strong the local signal is. But they don't tell you the ratio between that signal and the inevitable, and often very considerable, noise that accompanies it ..."

Iddo Genuth writes "Alaskan state officials have recently announced their intention to begin funding the exploration and surveying of Alaska's largest volcanoes in hopes of utilizing these as a source of geothermal energy. They say this volcano could provide enough energy to power thousands of households, and according to some estimates, Alaska's volcanoes and hot springs could supply up to 25% of the state's energy needs."

AmericanInKiev writes "Computer World posted a piece on Al Gore and his claim that solar cells will improve at the same rate as microprocessors. Vinod Khosla on the other hand has expressed disappointment that the doubling rate for price/performance of PV is 10 years rather than 18 months for transistors. Which of these two has the facts on their side?" Before anyone has him inventing the Internet again, note that Gore's claim as related in the article is much milder than that Moore's Law applies to solar cells per se -- namely, he's quoted as saying "We're now beginning to see the same kind of sharp cost reductions as the demand grows for solar cells." An optimistic statement, but not a flat-out silly one.

Solderingfool writes "MAKE Magazine's Phil Torrone and open source hardware hacker Ladyada from Adafruit Industries have a new video series called 'Citizen Engineer.' In the first video they show how a SIM card works, then build a SIM card reader which could be used to clone a SIM card. They also show how to use an old payphone as a regular home phone, later with coins, and for their final hack — how to 'Redbox' it. They released all the projects as open source, and the video is well produced."

director_mr writes "Tom's Hardware is running a story with an interesting description of a 28-qubit quantum computer that was developed by D-Wave Systems. They intend to open up use of their quantum computer to the public. It is particularly good at pattern recognition, it operates at 10 milliKelvin, and it is shielded to limit electromagnetic interference to one nanotesla in three dimensions across the whole chip. Could this be the first successful commercial quantum computer?"

lindik writes "As part of their research efforts aimed at building real-time human-level artificial vision systems inspired by the brain, MIT graduate student Nicolas Pinto and principal investigators David Cox (Rowland Institute at Harvard) and James DiCarlo (McGovern Institute for Brain Research at MIT) recently assembled an impressive 16-GPU 'monster' composed of 8x9800gx2s donated by NVIDIA. The high-throughput method they promote can also use other ubiquitous technologies like IBM's Cell Broadband Engine processor (included in Sony's Playstation 3) or Amazon's Elastic Cloud Computing services. Interestingly, the team is also involved in the PetaVision project on the Roadrunner, the world's fastest supercomputer."

griffjon writes "OLPCNews has a comparison of Windows XP to the Sugar/Linux OS on the One Laptop Per Child XO-1, based on the Microsoft Unlimited Potential video, touching on video recording, power usage, boot times, and mesh networking. An interesting, if saddening, read."

An anonymous reader writes "In an age of litigation and costly discovery obligations, many organizations are embracing policies which call for the forced purging of e-mail in an attempt to limit the organization's exposure to legal risk. I work for a large organization which is about to begin destroying all e-mail older than 180 days. Normally, I would just duck the house-cleaning by archiving my own e-mail to hard-drive or a network folder, but we are a Microsoft shop and the Exchange e-mail server is configured to deny all attempts to copy data to an off-line personal folder (.PST file). The organization's policy unhelpfully recommends that 'really important' e-mails be saved as Word documents. Is anybody doing this right? What do Slashdot readers suggest for a large company that needs to balance legal risks against the daily information and communication needs of its staff?"

mcgrof writes "Atheros has released a shiny new Atheros driver for all their 11n devices aimed for inclusion in the Linux kernel. This new driver has no proprietary HAL and is licensed under the ISC license, so the BSD community should be able to benefit as well. Note: no firmware required!"

perlow writes "While Solid State Drives are expensive and shouldn't be used exclusively for primary storage, they perform exceedingly well for things like MySQL databases, provided you tweak your kernel, BIOS, and filesystems accordingly. Here's a few tips to get excellent performance out of your new $500-$900 investment on a Linux system."

agent4256 writes "Barbara Robertson over at Studio Daily put forth this article featuring the technical background for the production of The Dark Knight. With most of the film shot with IMAX cameras (producing a theoretical resolution of 18k), the studios could not handle the size. Instead, they cut the resolution by more than half, down to 8K, the maximum resolution for scanned film. 'A single 8K frame requires 200 MB of data,' Franklin says. 'So we had to upgrade our whole infrastructure. We needed faster network speeds to move data around, massively beefed up servers, and — the most important thing — a new compositing solution.' To give you an idea of how far technology has taken us: 'In 1999, when we worked on Pitch Black [released in 2000], we needed to access 2 TB of data,' Franklin says. 'This show used over 100 TB of data.'"

MetaPhyzx writes "According to an article put forth by the Toward Freedom website, the metallic ore known as columbite-tantalite or coltan for short is fueling conflict in central Africa. The relevance to us who read news for geeks: Coltan is in quite a few consumer electronics; the article references the Sony Playstation series." As reader fahrvergnugen points out in the comments below, there's reason to more than doubt the currency of the claims in the above-linked article, as outlined in a post at Joystiq.

Barence sends along PcPro coverage of the second crash of London's Oyster card billing system in two weeks. Transport for London was forced to open the gates and allow free travel for all. "There is currently a technical problem with Oyster readers at London Underground stations which is affecting Oyster pay as you go cards only," explains the TfL website. This follows the first crash two weeks ago, which left 65,000 Oyster cards permanently corrupted. Speculation is increasing that the crashes may be related to the hacking of the Oyster card system by Dutch researchers from Radboud University, though TfL denies any link. Plans to publish details of the hack were briefly halted when the makers of the chip used in the system sued the group, although a judge ruled earlier this week that the researchers could go ahead. During the court action, details briefly leaked on website Wikileaks.

MechEMark writes with this excerpt from a hope-inspiring article at the IEEE Spectrum, which says "Researchers from Microsoft say they've built a prototype of a display screen using a technology that essentially mimics the optics in a telescope but at the scale of individual display pixels. The result is a display that is faster and more energy efficient than a liquid crystal display, or LCD, according to research reported yesterday in Nature Photonics ... The design greatly increases the amount of backlight that reaches the screen. The researchers were able to get about 36 percent of the backlight out of a pixel, more than three times as much light as an LCD can deliver. But Microsoft senior research engineer Michael Sinclair says that through design improvements, he expects that number to go up — theoretically, as high as 75 percent."

Brad Templeton writes "I (whom you may know as EFF Chairman, founder of early dot-com Clari.Net and rec.humor.funny) have just released a new series of futurist essays on the amazing future of robot cars, coming to us thanks to the DARPA Grand Challenges. The computer driver is just the beginning — the essays detail how robocars can enable the cheap electric car, save millions of lives and trillions of dollars, and are the most compelling thing computer geeks can work on to save the planet. Because robocars can refuel, park and deliver themselves, and not simply be chauffeurs, they end up changing not just cars but cities, industries, energy, and — by removing dependence on foreign oil — even wars. I, for one, welcome our new robot overlords." (More below.)

TechFiends32 writes "After years of working with NASA to bring Internet connectivity to deep space, scientists say Vint Cerf's efforts may be nearing completion. To combat the apparent challenges of extending the Internet into space (such as meteors and weighty, high-powered antennas), Cerf and others have made significant efforts, like adjusting satellite-based IP, and working on delay-tolerant networking (DTN) to address pure IP's limitations in space. According to principal engineer at The Mitre Corp., Keith Scott, 'The 2010 goal is designed to bring DTN to a sufficient level of maturity to incorporate it into designs for robotic and human lunar exploration.'"

Roland Piquepaille writes "Dutch engineers have built the third generation of the DelFly autonomous air vehicle. The DelFly Micro made its first public flight earlier today in Delft. This micro air vehicle weighs only 3 grams and has a wingspan of 10 centimeters. This very small remote-controlled aircraft carries a 0.4 gram camera. The DelFly Micro, which looks like a dragonfly, can fly for 3 minutes at a maximum speed of 5 meters/second. It could be used for observation flights in difficult-to-reach or dangerous areas."

snydeq writes "InfoWorld's Tom Yager takes a closer look at Apple's iPhone SDK confidentiality agreement, which restricts developers from discussing the SDK or exchanging ideas with others, thereby leaving no room for forums, newsgroups, open source projects, tutorials, magazine articles, users' groups, or books. But because anyone is free to obtain the iPhone SDK by signing up for it, Apple is essentially branding publicly available information as confidential. This 'puzzling contradiction' is the 'antithesis of the developer-friendly Apple Developer Connection' on which the iPhone SDK program is based, Yager contends. 'You'll see arguments from armchair legal analysts that the iPhone developer Agreements won't stand up in court — but those analysts certainly won't stand up in court on your behalf.' Anyone planning to launch an iPhone forum or open source project should have 'a lawyer draft your request for exemption, and make sure that the Apple staffer granting it personally commits to status as authorized to approve exceptions to the iPhone Registered Developer and iPhone SDK Agreements,' Yager warns."
