grunaura writes "South Korean researchers have devised a way to create graphene sheets one centimeter square using a hydrocarbon vapor on heated nickel. It's touted as being more efficient than the current process where graphene sheets are pressed, and there is evidence that 'the quality of graphene grown by chemical vapour deposition is as high as mechanically cleaved graphene.' Graphene is relatively new, but not to Slashdot. This round of news highlighting the technology focuses on the bendable nature of graphene sheets, as opposed to the memory applications or capacitive properties discussed here previously. These films are the closest we have come to superconductors at room temperature."

remove office writes "I recently discovered that Belkin's lead online sales rep, Michael Bayard, has been secretly paying internet users to review his company's products favorably on Amazon.com and other websites like Newegg, whether or not they've ever used the devices. Bayard instructed the people he was paying to 'Write as if you own the product and are using it... Mark any other negative reviews as "not helpful" once you post yours.' Ironically, he was using Amazon's own Mechanical Turk service to hire his fraudsters. Did he honestly think he wouldn't get caught? Are Slashdotters aware of other examples of other such blatant astroturfing on behalf of a large tech company like Belkin?"

marciot writes "I live in a condominium where I get interference from my neighbors' WiFi. I understand that 1, 6 and 11 are the only non-overlapping WiFi channels, but how does this translate into real-life best practices? When you must overlap, is there a 'good' way to do it? With nine access points, for example, is it better to have three APs each on 1, 6 and 11, so that each completely overlaps with only two others? Or is it best to distribute those APs across nine channels such that they only partially overlap others (but potentially overlap more APs in total)? Do use patterns affect interference? For example, is it best to overlap a channel with multiple APs that rarely transfers data, or to share a channel with one person who downloads torrents 24/7? Does maximum data rate affect interference or robustness to interference? I found out by accident that setting my access point to '802.11b only' mode appeared to give me a vastly more reliable connection that leaving it in 'mixed 802.11b/g.' Is this a fluke? Or does transmitting at 10 Mbps when everyone else is using 54 Mbps (for their 3 Mbps DSL pipes!) give you a true advantage?"

AnInkle writes "Two months after acknowledging that their flagship 1.5TB Barracuda 7200.11s could hang while streaming video or during low-speed file transfers, Seagate again faces a swell of complaints about more drives failing just months after purchase. Again, The Tech Report pursued the matter until they received a response acknowledging the bricking issue. Seagate says they've isolated a 'potential firmware issue.' They say there's 'no data loss associated with this issue, and the data still resides on the drive;' however, 'the data on the hard drives may become inaccessible to the user when the host system is powered on.' If users don't like the idea of an expensive data-laden paperweight, Seagate is offering a firmware upgrade to address the matter, as well as data recovery services if needed. By offering free data recovery, Seagate seems to be trying to head off what could become a PR nightmare that may affect several models under both the Seagate and Maxtor brands."

snydeq writes "Texas-based Saxon Innovations has filed a complaint with the US International Trade Commission to bar six companies — including Research in Motion, Palm, and Nokia — from importing handheld devices into the US. At issue are three patents that Saxon purchased in July 2007; a patent for keypad monitor with keypad activity-based activation; a patent for an apparatus and method for disabling interrupt marks in processors or the like; and a patent for a device and method for interprocessor communication by using mailboxes owned by processor devices. Saxon, with five employees, purchased about 180 US patents formerly owned by Advanced Micro Devices or Legerity in 2007, according to its ITC complaint."

An anonymous reader writes to tell us that a company has demonstrated a new form of wireless communication that uses light instead of radio waves. "Its inventor, St. Cloud resident John Pederson, says visible-light embedded wireless data communication is the next step in the evolution of wireless communications, one that will expand the possibilities in phone and computer use. The connection provides Web access with almost no wiring, better security and with speeds more than eight times faster than cable."

Visceralini writes "NVIDIA is launching yet another high-end 3D graphics offering, an optimized version of their top shelf GeForce GTX 280 single GPU card, dubbed the GeForce GTX 285. This new GeForce is a 55nm die-shrunk version of the legacy GTX 280 with lower power consumption characteristics that don't require an 8-pin PCI Express connector, rather just a pair of more standard 6-pin plugs. Performance metrics are shown here in a number of the latest game titles including Fallout 3, Left 4 Dead, Far Cry 2 and Mirror's Edge. The new GTX 285 is about on par or slightly faster than a GTX 280 but with less power draw and some room for overclocking over the reference design."

dooberrymctavish writes "You can now download an installer and bootloader for getting Debian running on your Android (G1 at the moment) device; the whole install process will take you about 10 minutes, and leaves you with access to the full plethora of programs available in Debian and lets you continue using your phone as it was intended to be: as an Android device with all the capabilities thereof. Here's a look at it running.

An anonymous reader writes "Researchers have developed a way to network household and commercial fridges together in a distributed peer-to-peer fashion that lets them 'negotiate' with each other on the best time to consume electricity. A retrofittable controller is attached to each fridge and then a temperature profile is built around the unit. The controller enables communication between other fridges on the network and also the power source. It enables fridges to work together to decide when to cool down, and thus consume power, based on how much surplus power will be available, and to anticipate power shortages and change their running schedules accordingly to use as little power as possible during these times."

snydeq writes "InfoWorld's Logan Harbaugh follows up his '10 IT Power-Saving Myths Debunked' to argue in favor of using DC power in the datacenter. The practice — viewed as a somewhat crackpot means for reducing wasteful conversions in the datacenter just a few short years ago — has gained traction to the point where server vendors such as HP, IBM, and Sun are making DC power supplies available in their server wares. Meanwhile, Panduit and other companies are working to bring down another barrier for DC to the datacenter: a standardized 400-VDC connector and cabling solution. And with GE working to list 600-VDC circuit breakers with the Underwriters Labs, DC's promise of reduced conversion waste could soon be commonly realized."

ThinSkin writes "Slashdot readers may remember an article regarding ExtremeTech's Loyd Case's experiences with solar power for the home after one month of usage. During that time six months ago, it sure seemed like a great deal, but the tables have turned significantly once winter approached. While it's no surprise solar power generation is expected to dwindle during the winter, Loyd compares solar power data of the last six months to determine if solar power is still worth the time and money."

jonr writes "At the recently concluded Consumer Electronics Show, Sony presented the new camera from its Cyber-shot product line. The DSC-G3 comes with a Zeiss lens with 4x zoom, a large 3.5" touch display, and 4GB of internal memory. Most interesting is the camera's software that includes, among other things, face and scene recognition, based on Busybox and Kernel 2.6.11 for the Access Linux Platform. The camera also has built-in Wi-Fi."

An anonymous reader writes "Sony's stand at CES had a small area set aside for flexible OLED screens, along with three mock-ups of possible OLED devices (including one stunning ultra-portable with no hinge and a single display for both screen and keyboard). There was also a working OLED screen being bent back and forth while playing a video clip. Does this mean roll-up, low-power colour screens will soon hit the market? Not unless OLED prices come down — Sony's stunning XEL-1 OLED TV costs $2,500, but only has an 11in screen ..."

jehovajerieh writes to us in the time-honored tradition of rampant Apple speculation, pointing to an article over on IBTimes suggesting that while the iPhone Nano may be on the way, the US might not be the first to experience this gadget bliss. "Despite limited information in the supplier channels and typical secrecy with new Apple products, insiders have confirmed that the iPhone nano is not yet in the testing labs at AT&T, Marshal says, leading him to believe that the launch will most likely be with a non-US carrier. 'Obviously, the best-case scenario here would be a China launch (~600mil+ wireless subscribers total in the country), but we have no definitive knowledge of this and are working on identifying the [locale] of launch and other pertinent details,' he said."

Harry McCracken writes "One of my top picks at the Consumer Electronics Show was Sixense's TrueMotion, a game-controller technology that resembles the Wii's remote, but uses an electromagnetic field to provide far more precision — it knows the exact location of the controller in 3D space and which way you're pointing it. (The Wiimote only knows which direction you're moving the controller.) TrueMotion-based remotes are due by Christmas, bundled with a PC game for under $100."

KentuckyFC writes "A group of electronics engineers have discovered that a thin layer of vanadium oxide acts as a memristor, the fourth basic component of circuits after resistors, capacitors, and inductors that was discovered last year. At a critical temperature, a current passing through the layer causes it to change from an insulating state to a metal-like state, thereby changing its resistance (abstract). The effect lasts many hours — which is what makes the layer a memristor (a resistor with memory). The team says this could be scaled up to make resistive random access memory, or RRAM, at very low cost, from little more than layers of vanadium oxide."

mcgrof writes "Linux developers have announced the release of a reverse-engineered open source firmware for Broadcom 4306 and 4318 wireless hardware, licensed under the GPLv2. 'Although the base firmware is not fully 802.11 compliant, e.g., it does not support RTS/CTS procedure or QoS, we believe that someone could be interested in testing it. The firmware does not require the kernel to be modified and it uses the same shared memory layout and global registers usage of the original stuff from broadcom to ease loading by the b43 driver.' You can go check out and download the firmware at the Italian Universita' Degli Studi Di Brescia Open FirmWare for WiFi networks project page. This is a good example of clean room reverse engineering design where one group worked on specifications while another worked on the the driver and the firmware. Kudos to the specification writers and bcm43xx development team for their hard work."

JadedApprentice writes "Caught a mention of this startup yesterday on CNBC while they were reviewing the latest gadgets at CES. In the off chance that there was anything remotely feasible or safe about the wireless power prototypes PowerBeam had on display, I took a quick google and found this nice little write-up on the technology (along with some priceless comments for those that scroll down, and I'm not talking about those on the page below). Bottom line: while it's possibly safe, it may not be efficient and it sure as hell won't power your 1200W gaming rig, the guys at PowerBeam are hoping the convenience of wireless power delivered through directed IR lasers will not only give you the coolest living room in town, but make them very rich in the process" This may be the only one using lasers, but there's a fair gaggle of wireless power schemes on the floor at CES. Besides several chargers limited to charging the controllers of specific game consoles, I walked through a working high-concept demo put on by PowerMat (also mentioned in that PC Magazine article), which relies on dedicated per-device sleeves and dongles to power cameras, phones, and other necessary pocket-fillers; the sleeve-equipped devices then sit to charge on one of the PowerMat induction mats. That means that if your gizmo isn't one for which a sleeve or dongle is available, you're out of luck, unless it uses AA or AAA batteries (there's a charger made to fit on the mat) or can be powered by USB (for which the company has hockey-puck sized USB-power sources, which, Yes, sit on the induction mat). Impressive, but at $30 a pop, that would mean a fair outlay to convert many gadgets to use such a system.

According to Symwave, this will result in 'speeds previously unattainable with legacy USB technology.' Which means, if you understand PR-write, it will be much faster."
