An anonymous reader writes "The Windows Vista SideShow technology shows some promise. But what about Linux devices that can present snippets of information independent of the main display? Here's a review of the picoLCD-4x20, a relatively inexpensive USB device ($50) that supports both SideShow on Vista and LCDproc on Linux."

MojoKid writes "Scientists in Pisa, Italy claim to have set a new world record for the fastest wireless data transmission. They report that they were able to achieve throughput speeds above 1.2 Terabits per second, which they say beats the previous wireless data transmission speed record of 160 Gigabits per second, achieved by Korean scientists. The technology that the Pisa scientists utilized actually shares a significant similarity with fiber optics. Unlike Wi-Fi or microwave communications, which use radio-based transmissions, the Pisa scientists used a technology called free-space optical communications. In free space optics, an energy beam is collimated and transmitted through space rather than being guided through an optical cable."

gurps_npc writes "CNN reports that a company called 'NAU' is working on an Immersion Cocoon that seems inspired by ST:TNG's Holodeck. The images are only 2D, and you can't touch them. But it is 360-degree video and sound, with light sensors to detect your hand movements and floor sensors to detect foot movements. They hope to have a prototype by October 2009."

alphadogg writes to mention that the same working group that brought you the standard for the 802.11n wireless communications is already poised to launch a gigabit Wi-Fi project. "Last year, group members formed the Very High Throughput (VHT) Study Group to explore changes to the 802.11 WLAN standard to support gigabit capacity. The study group is looking at doing so in two frequency bands, high-frequency 60GHz for relatively short ranges and under-6GHz for ranges similar to that of today's WLANs in the 5GHz band, 802.11a and 11n."

arcticstoat writes "Today marks fifty years since the first integrated circuit, or microchip, was demonstrated by Jack Kilby at Texas Instruments on 12 September 1958. The original chip might not be much to look at, but then Texas Instruments admits that Kilby often remarked that if he'd known he'd be showing the first working integrated circuit for the next 40-plus years, he would've 'prettied it up a little.' The integrated circuit itself was housed in a germanium strip on a glass slide, and it measured 7/16in by 1/16in. With protruding wires, and just containing a single transistor, some resistors and a capacitor, it's a primitive chip by today's standards, but it worked and successfully produced a sine wave on an oscilloscope screen at the demo. Technology hasn't been the same since."

Iddo Genuth writes "Scientists from Penn State University are designing the future of refrigerators and other cooling devices through magnetic field refrigeration. The investigation pertaining to electrically induced heat effects of some ferroelectric polymers might one day replace electrically powered refrigerators and their compressors and coils. The researchers are focusing on ferroelectric polymers that exhibit temperature changes at room temperature under an electrical field. The same technology might also find its way into computers and other devices in the future, making them run cooler without complex cooling mechanisms."

coderrr writes "SkyHook Wireless has been wardriving the US for years creating a huge database mapping wireless routers' MAC addresses to their physical locations. They provide an minimally documented API (docs here) which allows anyone to query the database directly for any MAC address. This could potentially allow some malicious individual to find out exactly where you live. Of course for them to get the MAC of your router in most cases will require either being infected with malware or some sort of social engineering attack... Imagine if you got a phishing email that included your home address."

Anonymous Coward writes "After Vint Cerf planned the Interplanetary Internet, there's a press release saying that the Interplanetary Internet is now being tested in space, using the Bundle Protocol developed by the Delay-Tolerant Networking Research Group. There's a conference paper with details on the testing too. These guys were previously the first to test IPv6 in space. Now they've found something with even fewer users than IPv6 to play with!"

notthatwillsmith writes "We've all heard a lot of big promises about how general-purpose GPU computing can greatly accelerate common tasks that are slow on the CPU — like H.264 video encoding. Maximum PC compared the GPU-accelerated Badaboom app to Handbrake, a popular CPU-based encoder. After testing a variety of workloads ranging from archival-quality DVD rips to transcodes suitable for play on the iPhone, Maximum PC found that while Badaboom is significantly faster than X264-powered Handbrake in a few tests that require video resizing, it simply can't compare to the X264-powered Handbrake for archival-quality DVD backups."

dominique_cimafranca writes "Shawn Frayne, a 28-year old inventor, has developed a small wind-powered generator that can be used to power small appliances in developing countries. Unlike the typical propeller design one expects of wind generators, the windbelt uses the oscillation of a membrane that follows the vibration of bridge. The oscillation drives small magnets which generate the electricity. From the article: 'Frayne's device, which he calls a Windbelt, is a taut membrane fitted with a pair of magnets that oscillate between metal coils. Prototypes have generated 40 milliwatts in 10-mph slivers of wind, making his device 10 to 30 times as efficient as the best microturbines. Frayne envisions the Windbelt costing a few dollars and replacing kerosene lamps in Haitian homes.'"

billybob2 writes "Lenovo has stopped selling laptops pre-installed with Linux on its web site, only 8 months after starting the trial program. This means that home customers won't be able to buy a Thinkpad without paying the Microsoft tax. Word has it that the decision to pull the plug on Linux came down from the highest levels of the Chinese company's corporate headquarters. For those looking to buy full-sized laptops and desktops with Linux pre-loaded Dell, System76, ZaReason and Everex all still offer such products."

DRMer writes "CE Pro has a series of stories that tries to untangle the legalities of DVD ripping in light of the recent RealDVD announcement from RealNetworks. In one of the stories, EFF Attorney Fred von Lohmann discusses the potential liability of those who resell or install DVD-ripping machines (the courts have yet to rule). Another article provides a rather amusing look at how manufacturers justify the legality of their products. Here's one example: 'We are just like Microsoft Vista that does not have a CSS [Content Scramble System] license.'"

Smivs writes "New research shows how steel will fail at high temperatures because of the magnetic properties of the metal. Scientists say an understanding of how the Twin Towers collapsed will help them develop the materials needed to build fusion reactors. The New York buildings fell when their steel backbones lost strength in the fires that followed the plane impacts. Dr Sergei Dudarev told the British Association Science Festival that improved steels were now being sought. The principal scientist at the United Kingdom Atomic Energy Authority (UKAEA) said one of the first applications for these better performing metals would be in the wall linings of fusion reactors."

snydeq writes "A lawsuit filed in a California court on Tuesday alleges Nvidia concealed the existence of a serious defect in its graphics-chip line for at least eight months 'in a series of false and misleading statements made to the investing public.' The lawsuit contends that Nvidia CEO Jen-Hsun Huang and CFO Marvin Burkett knew as early as November 2007 about a flaw that exists in the packaging used with some of the company's graphics chips that caused them to fail at unusually high rates. Nvidia publicly acknowledged the flaw on July 2, when it announced plans to take a one-time charge of up to $200 million to cover warranty costs related to the problem. That announcement caused Nvidia's stock price to fall by 31 percent to $12.98 and reduced the company's market capitalization by $3 billion, the lawsuit said. The lawsuit seeks class-action status against Nvidia and unspecified damages."

LostMyBeaver writes "I have been considering the purchase of an electric or hybrid vehicle for some time. The biggest problem I have currently is that both technologies make use of rechargable batteries. The same tree-huggers telling me gasoline is bad are telling me that batteries are bad too. I'm only partially knowledgable in this area, but it appears the battery technologies are generally based at least on lithium ion, nickel metal hydride, lead acid and nickel-cadmium. I was hoping someone on Slashdot would be knowledgable enough to explain the environmental cost of recycling these batteries. If I understand correctly, after these chemicals are 'spent' so the cells no longer maintain a charge, they are not useful for producing new batteries. I can only imagine that the most common method of recycling the cells is to store the toxic chemicals of the batteries in barrels and refilling the cells with new chemicals. This sounds like an environmental disaster to me. Is there someone here that can help me sleep better at night by explaining what really happens?"

snydeq writes "Organizations looking to remain profitable in the face of escalating energy costs may lean even harder on IT to achieve energy efficiencies in the years to come, InfoWorld reports. But instead of limiting IT's efficiency role to the datacenter, companies will tap IT's vast knowledge of company networks, equipment, and work processes to uncover efficiencies across the organization, in some cases tipping facilities management into IT. 'There is a lot IT can do to fix its own 2 percent [of the company's carbon emissions] and make it more efficient, but the big opportunity for IT is to take a leadership role in tackling that other 98 percent across the business,' says one analyst. And by taking charge of the organization's energy strategy now, IT will be in prime position to alter its relationship with management and reap benefits in the boardroom in the years ahead, analysts contend."

Mike writes "The Security Group at the University of California in Santa Barbara has released the video that shows the attacks carried out against the Sequoia voting system. The video shows an attack where a virus-like software spreads across the voting system. The coolest part of the video is the one that shows how the 'brainwashed' voting terminals can use different techniques to change the votes even when a paper audit trail is used. Pretty scary stuff. The video is absolute proof that these types of attacks are indeed feasible and not just a conspiracy theory. Also, the part that shows how the 'tamperproof' seals can be completely bypassed in seconds is very funny (and quite disturbing at the same time)."
