Brian D. writes "I've recently begun working with a group that sends books to prisoners in federal and state prisons. We try to match their requests as well as we can. One request that we consistently have trouble filling is for computer books. This is not for lack of books, but because the prisoners' requests tend to be vague and their computer resources are obviously severely limited. Keep in mind that we send prisoners all types of books — from gardening and landscaping to cooking and sailing — about topics they don't have the resources to experiment with. With basically one shelf devoted to books on computing, what types of books should I tell them we should keep? What are the best types of books to send a prisoner who requests a book on 'computer repair?'"

CryoStasis writes "I am a graduate student getting my degree in biomedical sciences. Because my work often requires me to maintain a local sterile environment (under a biological hood) I find that I am unable to physically touch my computer, which sits beside me, in order to open my notes, protocols, etc. while I'm working. As a result, I have begun to search for a voice-recognition program that will allow me to tell the computer what files/programs to launch. I know that the general field of voice recognition has come a long way, but I find that the built-in speech recognition systems in both OS X and Vista are clunky and difficult to use. Are there any good, cross-platform speech-recognition programs available that might fit the bill?"

twitter writes "Analysts at Bloomberg noticed the tumble in Microsoft's traditional software sales last quarter and blamed it on netbooks: 'The devices, which usually cost less than $500, are the fastest-growing segment of the personal-computer industry — a trend that's eating into Microsoft's revenue. Windows sales fell short of forecasts last quarter and the company cut growth projections for the year, citing the lower revenue it gets from netbooks. When makers of the computers do use Windows, they typically opt for older and cheaper versions of the software. Equipping Linux on a computer costs about $5, compared with $40 to $50 for XP and about $100 for Vista, according to estimates by Jenny Lai, a Taipei-based analyst at CLSA Ltd.' This is why MS declared war on the segment last year and palm top computers in previous years. While they may have successfully tamed the Asus EEE PC, they can't hold back everyone who wants to make a buck on cheap hardware and free software. Analysts have predicted the fall of MS's business model when computers break below $250/unit retail. We are there now, and it has shown in the bottom line."

An anonymous reader writes "A startup named Mgestyk Technologies claims that they have an affordable solution for 'Minority Report'-like PC control. They have released a video in which they use hand gestures to play games like Halo and Guitar Hero, as well as perform 'multi-touch' interactions for applications like Google Earth. Engadget and Gizmodo discuss the potential of the technology but point out that the system has visible lag when used for gaming. Will camera-based interfaces ever meet the low-latency demands of gaming? For how much longer will we still be using keyboards, mice and joysticks?"

arcticstoat writes to mention that Toshiba's latest line of high-powered laptops has three GPUs included. Both the Qosmio X305-Q706 and Q708 come with an integrated GeForce 9400M for day-to-day processing tasks but have a pair of GeForce 9800Ms in SLI that kick in when you need the extra horsepower. "The [Qosmio] X305-Q706 costs $1,999 US (£1,257) in the US, although we haven't seen any UK pricing on the laptops yet. The system comes with a 2.2GHz Core 2 Duo P8400 and 4GB of RAM, while the costlier X305-Q708 comes with a quad-core 2.53GHz Core 2 Extreme QX9300 CPU."

hedonisticaltruism writes "The CBC reports that Honda has just unveiled a new walking-assist device that enhances the walking motion rather than just providing transportation. The device braces and strengthens natural leg movements primarily in walking and crouching. They're looking to market this to rehabilitation cases, the handicapped and industries requiring repetitive crouching and walking movements such as factory work and delivery services."

Glenn Fleishman writes "The reports earlier today on WPA's TKIP key type being cracked were incorrect. I spoke at length with Erik Tews, the joint author of the paper that discloses a checksum weakness in TKIP that allows individual short packets to be decrypted without revealing the TKIP key. I wrote this up for Ars Technica with quite a bit of background on WEP and WPA. Tews's paper, co-written with Martin Beck, whom he credits as discovering and implementing a working crack (in aircrack-ng as a module), describes a way to use a backwards-compatible part of TKIP to exploit a weakness that remains from WEP. ARP packets and similarly short packets can be decoded. Longer packets are likely still safe, and TKIP hasn't been cracked. Don't believe the hype, but the exploit is still notable."

An anonymous reader writes "In a move that's a win for the free software community, Creative Labs has decided to release their binary Linux driver for the Creative Sound Blaster X-Fi and X-Fi Titanium sound cards under the GPL license. This is coming after several failed attempts at delivering a working binary driver and years after these sound cards first hit the market."

mallumax writes "David Pogue of New York Times has reviewed the Pico, which is a pocket projector from Optoma. The review is quite entertaining (Pogue projects the images on to a plane's ceiling, leaving passengers baffled) and detailed. The highlights are: It is a pocket-sized projector which runs on batteries and can project images and videos from a variety of sources like iPhone, iPod and DVD players with a 480x320px resolution, with a maximum screen size of 65 inches at 8.5 feet. It uses a non-replaceable 10,000 hour LED lamp and a DLP chip from Texas Instruments. The battery lasts for 90 minutes and can be recharged through USB or with its own power cord. The device weighs 115g and comes with an inbuilt speaker which is practically useless. If you want one, it will set you back by $430."

Peter (Professor) Fo writes "I've recently had two CD-Rs reported to me as faulty which are just 3 years old. This is worrying — I suspect the failure rate for this batch could be 10%. When researching CD longevity there is old and unreliable information; pious 'how to cosset your discs so they last 100 years' blurb; and endless discussions of what sort of dye to use, don't use cheap media, burn slower (or don't), but not much by way of hard facts besides there's a lot of data loss going on. Does anyone know of a generic utility (win or *nix would suit me) that can map sector readability/error rates of CDs? I'd like to measure decay over time in my environment with my media and my other variables; and I expect others would too."

narramissic writes "Researchers Erik Tews and Martin Beck 'have just opened the box on a whole new hacker playground, says Dragos Ruiu, organizer of the PacSec conference. At the conference, Tews will show how he was able to partially crack WPA encryption in order to read data being sent from a router to a laptop. To do this, Tews and Beck found a way to break the Temporal Key Integrity Protocol (TKIP) key, used by WPA, in a relatively short amount of time: 12 to 15 minutes. They have not, however, managed to crack the encryption keys used to secure data that goes from the PC to the router in this particular attack. 'Its just the starting point,' said Ruiu."

Banana ricotta pancakes writes "Microsoft has confirmed that there will be a widespread public beta of Windows 7 in early 2009, while urging device manufacturers to start immediate testing with its pre-beta release to avoid the widespread hardware compatibility problems that contributed so much to the negative perception of Vista. 'There is not another WinHEC planned before Windows 7 is released,' Microsoft has warned them. Better hope that testing goes well."

An anonymous reader writes "T-Mobile's G1 phone, the first commercially available Android based phone, has been rooted. The exploit is extremely simple to execute, just requiring you to run telnetd from a terminal on the phone, and then connecting to the phone via telnet."

sidesh0w was one of a number of readers to alert us to the FCC's unanimous decision approving unlicensed devices to use the white spaces of the spectrum unused by television broadcasters, provided they take certain precautions not to interfere with licensed users. "Denying a tremendous last-minute lobbying effort by broadcasters, the vote on white space devices went ahead as planned today after a several-hour delay at FCC headquarters. When the vote came, though, it was unanimous. For the Democrats on the Commission, the devices are appealing because they offer a potential new avenue for broadband services, while the Republicans are pleased for the same reasons, but love the fact that this is a deregulatory order that focuses on less regulation and more competition."

Fluffeh alerts us to a report of a fungus that naturally produces diesel fuel, or something very close to it. "A fungus that lives inside trees in the Patagonian rain forest naturally makes a mix of hydrocarbons that bears a striking resemblance to diesel, biologists announced today. And the fungus can grow on cellulose, a major component of tree trunks, blades of grass and stalks that is the most abundant carbon-based plant material on Earth. ... [T]the paper's authors admit that the technique is far from any sort of industrial production. 'This report presents no information on the cost-effectiveness or other details to make G. roseum an alternative fuel source,' they write." NPR has an interview with the fungus's discoverer.

ptorrone writes "Inventor Mitch Altman explains why he open-sourced his TV-B-Gone kit, the original stealth keychain fob for defeating TVs in public places. The title of the article is 'Patent-B-Gone' and perhaps the most interesting fact is that Mitch's brother is a patent attorney, but he still decided to release an open source hardware version of the TV-B-Gone, with pretty impressive results."

Tjeerd writes "Because the 'green revolution' is accelerating, I felt it was time to get involved. Last week I started with buying a portable solar energy charger for my mobile phone. But soon I was thinking of also recharging my Asus Eee netbook with a portable solar energy recharger. I found things like the Portable Power Pack, Foldable Solar Chargers, and the Solar Gorilla. The Solar Gorilla looks quite interesting and might be able to recharge my netbook and fits nicely in a rucksack. But I would like some real-life feedback. If you have experience with these or other portable solar devices, what has worked for you?"

Wired has an interview with Alan Kay on the occasion of the 40th anniversary of the idea of the laptop computer. Kay's vision, which he dubbed the "Dynabook," was for a 2-pound, 1-Mpixel color computing device. "... the Dynabook was never built. But it greatly inspired the devices we now call laptops, although it's taken four decades to slim the tech down to the point where usable computers actually weigh as little as two pounds. To honor his achievements, Mountain View's Computer History Museum on Wednesday will celebrate the 40th anniversary of the legendary Dynabook. [Quoting Kay:] 'The Amazon Kindle is kind of a subset of a Dynabook — too much of a subset. The screen is too small, it is not very capable of dynamics, the keyboard is poor, etc. But it does have several limited service ideas that are good. The next version of a Kindle could be really exciting.'"
