mattnyc99 writes "There was plenty of chatter last week about an MIT announcement that researcher Angela Belcher had developed a way to create virus-based nanoscale batteries to power mini gadgets of the future. In a fascinating followup at Popular Mechanics, Belcher now says that her unpublished work includes full-scale models of the batteries themselves, and that they could power everything from cars and laptops to medical devices and wearable armor. Quoting: 'We haven't ruled out cars. That's a lot of amplification. But right now the thing is trying to make the best material possible, and if we get a really great material, then we have to think about how do you scale it.'"

kgagne writes "While solid state disk drives can vastly improve random read performance and are perfectly suited to most mobile devices, many operations are sequential in laptops and desktops and involve writes where SSDs most often lose to magnetic hard disk drives in performance. While introducing multi-channel flash memory controllers and interleaving the NAND flash chips increases performance, it will still be about two years before the cost versus benefit ratio will make sense to install SSD in your laptop or desktop PC, according to a Computerworld story. '"I think you need to get to 128GB for around $200, and that's going to happen around 2010. Also, the industry needs to effectively communicate why consumers or enterprise users should pay more for less storage," says Joseph Unsworth, an analyst at Gartner Inc.'"

cce writes "The MicroID standard, despite getting thrashed soundly by Ben Laurie two years ago, has since been recommended by the DataPortability Project and published on the user profiles of millions of users at Digg and Last.fm. MicroID is basically a hash calculated using a user's profile page URL and registered email address, producing a token that makes the email address vulnerable to dictionary attacks. To see how easy it was to crack these tokens, I conducted a small study, choosing 56,775 random Digg users, and cracking the email addresses of 14,294 of them (25%) using just their MicroID, username, and a list of popular email domains. Digg has more than 2 million users, and that means half a million of them — mostly people who had never heard of MicroID, and had probably not logged in for a long time — had their email addresses exposed to this trivial attack. I also applied this attack to Last.fm (19%) and ClaimID (34%). Digg and Last.fm have since removed support for MicroID, but the lesson is clear: don't publish a hash of my email address online, guys!"

at0mic26 writes "I am currently tasked with finding a cost effective solution to our 30+ degree Celsius server room. The only air conditioning currently provided is a single duct pipe from one of two air conditioner units. I was thinking of stealing air from the second air conditioning unit with some sheet metal work, but it likely will not be sufficient — and would not have tolerance for both AC units being offline for any amount of time. An ideal supplemental portable AC unit is what I am after, however I'm finding it cost prohibitive, with $600+ humidity controlled AC unit, plus 20 amp socket requirement, plus contract work to make a hole in the wall for outside drainage so that the unit does not flood the place. What sort of successful cheaper air conditioning solutions have you come up with?"

Steve Kerrison writes "Taiwanese technology firm Abit will be pulling out of the mainboard market at the end of this year. HEXUS.channel, citing sources close to South East Asian distributors, reports that the company will continue to deliver mainboard products until the end of 2008 and will still honour all warranties in subsequent years. Rumours of this decision circulated in May but were dismissed. Apparently the decision was made in the last couple of weeks. Abit is a popular brand amongst PC hardware enthusiasts, many of whom will be disappointed to see it leave the market."

Vigile writes "In a somewhat surprising move from a company that is used to holding its proprietary technologies close to its chest, NVIDIA has announced that it is opening up a 'certified SLI motherboard' program for boards using the upcoming Intel X58 chipset. The X58 is Intel's core logic offering for Nehalem/Bloomfield processors and many people wondered how NVIDIA would support SLI on a platform for which they had admitted to not developing a chipset. At first, NVIDIA was pushing the use of their dedicated nForce 200 chip, but have instead decided to open up the SLI technology to X58 motherboards that meet certain NVIDIA requirements. This leaves a lot of questions about NVIDIA's previous SLI statements, how the pricing of the certification affects partners, and if NVIDIA's chipset business is truly at its end now."

DesScorp writes "The Times reports on the problems of adding wind farms to the power grid. Because of the grid's old design, it can't handle the various spikes that wind farms sometimes have, and there's no efficient way to currently move massive amounts of that power from one section of the country to the other. Further complicating things is the fact that under current laws, power grid regulation is a state matter, and the Federal government has comparatively little authority over it right now. Critics are calling for federal authority over the grid, and massive new construction of 'superhighways' to share the wind power wealth nationally. Quoting the article, 'The dirty secret of clean energy is that while generating it is getting easier, moving it to market is not.'"

AlHunt writes "I've been tasked with finding a way to bury digitally stored photographs in a small underground time capsule to be opened in 25 years. It looks like we'll be using a steel vessel, welded closed. I've thought of CDs, DVDs, a hard drive, or a thumb drive — but they all have drawbacks, not the least of which is outdated technology 25 years from now. Maybe I'll put a CD and a CD-ROM drive in the capsule and hope that the IDE interface is still around in 25 years? Ideas and feedback will be appreciated."

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."

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 surface can be captured. The two captured images essentially become a reflectance map (albedo) and a depth map (height field)."

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.' He was also dismissive of the threat from Intel's Larrabee architecture, following Nvidia's chief architect calling it a 'GPU from 2006' at the weekend."

Barence writes "Meet the Space Cube — the world's smallest fully functional PC. Primarily designed for use in space, it somehow manages to cram a working PC with USB ports, card readers, audio outputs and proprietary interfaces into a tiny cube chassis measuring just two inches square. It runs a basic Linux front-end, which the blogger takes a look at, and there are some great photos of the device being loomed over by everyday objects like coffee mugs and cellphones. It has connections for controlling various electronics used by ESA, NASA and JAXA, but it will also apparently be for sale to the public soon, for use by amateur engineers and robotics clubs."

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."

My question to Slashdot is: How do you organize all of your different chargers? Please, share your secrets."

dominique_cimafranca notes a story up at the Daily Mail in the UK about a partially paralyzed man who is able to walk again using an exoskeleton frame. The article goes a bit far in comparing the device to Robocop, but it does show pictures of the man, paralyzed for the last 20 years, regaining some use of his legs. Quoting: "The device, called ReWalk, is the brainchild of engineer Amit Goffer, founder of Argo Medical Technologies, a small Israeli high-tech company. Something of a mix between the exoskeleton of a crustacean and the suit worn by Robocop, ReWalk helps paraplegics — people paralyzed below the waist — to stand, walk and climb stairs. The system, which requires crutches to help with balance, consists of motorized leg supports, body sensors and a back pack containing a computerized control box and rechargeable batteries."

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."

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."

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."

CurtMonash writes "I had been a database industry analyst for a decade before I found 1-gigabyte databases to write about. Now it is 15 years later, and the 1-petabyte barrier is crumbling. Specifically, we are about to see data warehouses — running on commercial database management systems — that contain over 1 petabyte of actual user data. For example, Greenplum is slated to have two of them within 60 days. Given how close it was a year ago, Teradata may have crossed the 1-petabyte mark by now too. And by the way, Yahoo already has a petabyte+ database running on a home-grown system. Meanwhile, the 100-terabyte mark is almost old hat. Besides the vendors already mentioned above, others with 100+ terabyte databases deployed include Netezza, DATAllegro, Dataupia, and even SAS."

calmond writes with this excellent snippet from CNET News: "QinetiQ Group PLC claimed Sunday that its propeller-driven aircraft called Zephyr flew for 83 hours and 37 minutes non stop, more than doubling the official world record set by Northrop Grumman's Global Hawk in 2001. The Zephyr is much different from the Global Hawk, which is about the size of a fighter and requires runway for taking off and landing. Zephyr, on the other hand, is an ultra-lightweight carbon-fiber aircraft that weighs less than 70lbs and is designed to launch by hand. The little aircraft flies on solar power generated by amorphous silicon arrays covering the aircraft's paper-thin wings. It is powered day and night by rechargeable lithium-sulfur batteries that are recharged during the day using solar power."
