holy_calamity writes "New Scientist reports that the first working superconducting transistor has been created, by researchers at the University of Geneva. Field effect transistors with zero electrical resistance would allow much faster operations. Only drawback is they need to be supercooled, something that may be addressed by improving the materials used."

SpaceAdmiral notes the news that scientists have succeeded in convincing experiment subjects that a mannequin's body is their own, and even feeling at home in the body of someone of the opposite sex. The effect could prove useful in virtual reality applications and in robot technology. Here's the paper on PLoS ONE.

Richard Kelleher writes "It seems the current design of multi-core processors is not good for the design of supercomputers. According to IEEE: 'Engineers at Sandia National Laboratories, in New Mexico, have simulated future high-performance computers containing the 8-core, 16-core, and 32-core microprocessors that chip makers say are the future of the industry. The results are distressing. Because of limited memory bandwidth and memory-management schemes that are poorly suited to supercomputers, the performance of these machines would level off or even decline with more cores.'"

Cyberhwk writes "I have a system with Windows Vista Ultimate (64-bit) installed on it, and it has 4GB of RAM. However when I've been watching system performance, my system seems to divide the work between the physical RAM and the virtual memory, so I have 2GB of data in the virtual memory and another 2GB in the physical memory. Is there a reason why my system should even be using the virtual memory anymore? I would think the computer would run better if it based everything off of RAM instead of virtual memory. Any thoughts on this matter or could you explain why the system is acting this way?"

KrispyDroid writes "The world's second Google Android phone has been unveiled — by an Australian-based electronics company called Kogan. It will ship worldwide on Jan 29. It looks like a surprisingly nice form factor, not unlike a Blackberry Bold. The phones will be sold without a contract at low prices — $A299 ($US192)."

Lumenary7204 writes "According to the Register, Apple recently received US Patent Application No. 20080291629 for a 'liquid-cooled portable computer.' The filing describes a system where a 'pump ... coupled to the heat pipe is configured to circulate the liquid coolant through the heat pipe.' All claims of obviousness aside (after all, PC enthusiasts have been using liquid and phase-change cooling for years), the existence of the patent application seems to indicate that laptop manufacturers are in agreement with physicists and engineers who say we are running up against the practical limits of air-cooling such compact pieces of equipment."

alphadogg writes "It's possible that in the future conversations on your cell phone could generate enough electrical power to run the phone, without batteries. That's one possible outcome of recent work by a team of Texas researchers, who appear to have discovered that by building a certain type of piezoelectric material to a specific thickness (about 21 nanometers, compared to a typical human hair of 100,000 nanometers), you can boost its energy production by 100 percent. And the technology could power not just phones, but a whole range of low-power mobile devices and sensors. The breakthrough is an example of 'energy harvesting' that can convert one kind of energy, such as vibrations or solar rays, into electricity."

Buckbeak writes "I like to carry my Linux systems around with me, on USB flash drives. Typically, SanDisk Cruzers or Kingston HyperX. I encrypt the root partition and boot off the USB stick. Sometimes, the performance leaves something to be desired. I want to be able to do an 'apt-get upgrade' or 'yum update' while surfing but the experience is sometimes painful. What can I do to maximize the performance of Linux while running off of a slow medium? I've turned on 'noatime' in the mount options and I don't use a swap partition. Is there any way to minimize drive I/O or batch it up more? Is there any easy way to run in memory and write everything out when I shut down? I've tried both EXT2 and EXT3 and it doesn't seem to make much difference. Any other suggestions?"

Barence writes "Mobile broadband speeds could hit a blistering 42Mb/sec as early as next year, according to Ericsson's chief technology officer. The idea seems far-fetched given that even the fastest dongles currently hover at around 7.2Mb/sec, but the technology to smash that barrier is thought to be just around the corner. One of the methods is very similar to the MIMO technology already used in draft-N wireless routers, but Ericsson believes a combination of factors may even squeeze that figure to 80Mb/sec in the longer term."

An anonymous reader writes "For copyright activists, Christmas comes but once every three years: a chance to ask Santa for a new exemption to the much-hated Digital Millennium Copyright Act's prohibitions against hacking, reverse engineering and evasion of Digital Rights Management (DRM) schemes protecting all kinds of digital works and electronic items. Judging from the list of 20 exemptions requested this year [19 shown], some in the cyber-law community are thinking big. The requests include the right to legally jailbreak iPhones in order to use third party software, university professors wishing to rip clips from DVDs for classroom use, YouTube users wishing to rip DVDs to make video mashups, a request to allow users to hack DRM protecting content from stores that have gone bankrupt or shut down, and a request to allow security researchers to reverse engineer video games with security flaws that put end-users at risk." Reader MistaE provides some more specific links to PDF versions: "Among the exemption proposals is a request from the Harvard Cyberlaw Clinic to allow circumvention of DRM protection when the central authorization server goes down, a request from the EFF to allow circumvention to install third party programs on phones, as well as a request for ripping DVDs for non-commercial purposes. There were also several narrow requests from educational institutions to rip DVDs for classroom practices."

Ashmash writes "Phoronix has put out a fresh series of benchmarks that show the real world performance of the Ext4 file-system. They ran 19 tests on Fedora 10 with changing out their primary partition to test Ext3, Ext4, Xfs, and ReiserFS. The Linux 2.6.27 kernel was used with the latest file-system support. In the disk benchmarks like Bonnie++ Ext4 was a clear winner but with the real world tests the results were much tighter and Xfs also possessed many wins. They conclude though that Ext4 is a nice upgrade over Ext3 due to the new features and just not improved performance in a few areas, but its lifespan may be short with btrfs coming soon."

Smivs writes "Logitech has hailed as a major landmark the production of their one billionth computer mouse. The news comes at a time when analysts claim the days of the mouse are numbered. 'It's rare in human history that a billionth of anything has been shipped by one company,' said Logitech's general manager Rory Dooley. 'Look at any other industry and it has never happened. This is a significant milestone.' The computer mouse will achieve a milestone of its own next week when it turns 40. It was 9 December 1968 when Douglas C. Engelbart and his group of researchers at Stanford University put the first mouse through its paces."

Dorian Cox, the 27-year-old guitarist of the indie band The Long Blondes, thought his guitar playing days were over after he suffered a stroke. He now has a glimmer of hope thanks to some neurological physiotherapy which includes a cutting-edge piece of medical technology. The SaeboFlex helps patients by supporting their wrists and helping them grasp and release objects. "It's a fantastic service, it's helping tremendously and I think it can work wonders for me and others — it's almost like a gym for my hand. I know things might never be the same again and nobody can give me a definite answer about whether I'll play guitar again but I'm getting back on track with their help," Mr. Cox said. This thing looks really cool, and I'm sure many people will benefit from it, though I can't help but wonder if they make a model that lets you shoot your fist at an enemy.

stinkymountain writes "Writer John Brandon spent two days at Microsoft Research Labs in Redmond and got an inside look at some pretty interesting projects under development, including a robotic receptionist, a new type of touch screen for people with fat fingers, and an electronic table that allows multiple people to collaborate in real time. Brandon also talks about some of these research projects on this NPR podcast."

An anonymous reader writes "Now that Intel has unleashed its next-generation Core i7 processors, all eyes are turned to AMD and its incoming wave of 45nm CPUs. To get a feel for AMD's future competitiveness, The Tech Report has taken a pair of 2.7GHz 45nm Opterons (with 75W power envelopes) and put them through the paces against Intel Xeons and older, 65nm Opterons in an extensive suite of performance and power efficiency tests — from Cinema 4D and SPECjbb to computational fluid dynamics and a custom XML handling benchmark. The verdict: AMD's new 45nm quad-core design is a notable improvement over the 65nm iteration, and it proves to be a remarkably power-efficient competitor to Intel's Xeons. However, 45nm AMD chips likely don't have what it takes to best Intel's Core i7 and future Nehalem-based Xeons."

Dave Bullock (eecue) writes "Scientists at UCLA have accidentally created a material that will some day give us better, faster, cheaper, more flexible digital cameras. I toured their lab and shot a photo essay for Wired. Personally I'm looking forward to a quantum-dot embedded camera sensor someday soon. 'Graduate student Hsiang-Yu Chen was working on a new formula for solar cells when something went wrong. Instead of creating electricity when hit with light, the conductivity of the material she was working with changed. "The original purpose [was] to make a solar cell more efficient," says Chen. "However, during the research we found the solar cell phenomenon [had] disappeared." Instead, the test material showed high gain photoconductivity, indicating potential use as a photo sensor.'"

jbolden writes "According to the Wall Street Journal, the FCC is considering a plan to provide free wireless internet. The plan would involve some level of filtering, but might allow adults to opt out. CTIA has argued that this business model has traditionally failed (see Slate magazine's analysis as to why)."

chrb writes "With the recent discussion here on proprietary blobs in the Linux kernel, it's nice to see that today Sam Leffler has released the source for the Atheros Hardware Abstraction Layer under the ISC license, which is both GPL and BSD compatible. The Atheros chipset is used in many laptops, so this is another important step towards running a completely free distribution."

kev009 writes to recommend his editorial overview of the past, present and future of Linux file systems: ext2, ext3, ReiserFS, XFS, JFS, Reiser4, ext4, Btrfs, and Tux3. "In hindsight it seems somewhat tragic that JFS or even XFS didn't gain the traction that ext3 did to pull us through the 'classic' era, but ext3 has proven very reliable and has received consistent care and feeding to keep it performing decently. ... With ext4 coming out in kernel 2.6.28, we should have a nice holdover until Btrfs or Tux3 begin to stabilize. The Btrfs developers have been working on a development sprint and it is likely that the code will be merged into Linus's kernel within the next cycle or two."
