Knee Brace Generates Electricity From Walking 128

Posted by Soulskill
from the runs-on-walks dept.
ktulus cry brings news of a device that can power portable gadgets, prosthetic joints, and other mobile appliances by harvesting energy generated by walking. Researchers are working on making the device — still a moderately cumbersome 3.5 pounds — smaller while maintaining its energy harvesting capacity. CNet has a write-up with more pictures and a diagram of the device. "In the mode in which the brace is only activated while the knee is braking, the subjects required less than one watt of extra metabolic power for each watt of electricity they generated. A typical hand-crank generator, for comparison, takes an average of 6.4 watts of metabolic power to generate one watt of electricity because of inefficiencies of muscles and generators. A lighter version would be helpful to hikers or soldiers who don't have easy access to electricity. And the scientists say similar mechanisms could be built into prosthetic knees other implantable devices such as pacemakers or neurotransmitters that today require a battery, and periodic surgery to replace that battery."

A few days ago we posted a story for you to discuss the best presidential candidates for Super Tuesday, but I figured it would be an interesting idea to try that again, but split the discussion into 2 halves. This is the Republican half — please only discuss the Republican candidates in this story. Huckabee, McCain, and Romney only.

Zero-day Exploit in PDF With Adobe Reader 188

from the be-on-alert dept.
hankwang writes "Security researcher Petko Petkov, who is known for his recent discovery of a vulnerability with Quicktime in Firefox, claims to have discovered an exploit that allows arbitrary code execution when a maliciously crafted PDF document is opened in any version of Adobe Reader. Petkov did not disclose any technical details other than a video, but claims on his blog that Adobe has acknowledged the vulnerability. If this exploit goes wild, it could cause some serious problems, as PDFs are usually automatically opened from web browsers and widely used and trusted by corporate users."

More Details on Dungeons and Dragons Fourth Edition 45

Gamespy had a chat with Chris Perkins, story manager for Dungeons and Dragons R&D, at this year's Gen Con. Though Chris had no more details to offer Gamespy than he did for us at the event, the piece puts a lot of information all into one place on what we can expect from D&D Fourth Edition. "GameSpy: We've been reading a lot about talent trees in 4th Edition ... Christopher Perkins: Talent trees aren't unique to MMORPGs. Wizards has produced other games that use talent trees, such as the d20 Modern Roleplaying Game and the Star Wars Roleplaying Game Saga Edition. The theory of game design, regardless of platform, is constantly evolving. We've taken our gaming experiences over the past decade, as well as player feedback on the games and supplements we've produced in that time period, to build a system for character creation and advancement in 4th Edition that draws inspiration from numerous sources, but isn't exactly like anything that's been done before."

JSM writes to tell us that Apple released a new version of their popular iPod music player today that boasts, among other things, an iPhone-like touch screen and Wi-Fi capabilities. "The iPod Touch will feature the Safari Internet browser and, like the iPhone, play YouTube videos. Apple also announced a new version of its iTunes music store that will allow users to buy songs wirelessly. iTunes will also sell customizable 99-cent ringtones for the iPhone."

Apple May Introduce New iPod on Wednesday 190

from the tiny-christmas dept.
UnHolier than ever writes "Apple may be planning to announce a 'revamp' of the iPod on Wednesday. Reporters from across Europe have been asked to view a broadcast presentation by Steve Jobs at the BBC headquarters. Theorized features for this new iPod include a full or wide-screen with touch controls, ala the ever-popular iPhone. '[An analyst with Goldman Sachs] believes that a new line of iPods will boost demand for the gadget from Goldman's present forecast of about 19.8 million units for Apple's key first quarter - the reporting period that covers Christmas. However, that still suggests that demand for iPods will be flat, at best, compared with the same period last year, when Apple sold about 21 million devices.'"

Gamma Ray Anomaly Could Test String Theory 128

from the finally-experimental-data dept.
exploder writes "String theory is notorious for its lack of testable predictions. But if the MAGIC gamma-ray telescope team's interpretation is correct, then a delay in the arrival of higher-energy gamma rays could point to a breakdown of relativity theory. A type of 'quantum lensing effect' is postulated to cause the delay, which is approximately four minutes over a half-billion year journey." Ars's writeup is a little more fleshed-out than the Scientific American blog posting.

"Crowd Farm" to Collect Energy? 357

from the kriss-kross-to-make-comeback dept.
Cain writes to mention that a couple of MIT students would like to harness the mechanical power of large groups of people. "A Crowd Farm in Boston's South Station railway terminal would work like this: A responsive sub-flooring system made up of blocks that depress slightly under the force of human steps would be installed beneath the station's main lobby. The slippage of the blocks against one another as people walked would generate power through the principle of the dynamo, a device that converts the energy of motion into that of an electric current."

Under User Pressure, SugarCRM Adopts GPLv3 162

StonyandCher writes "SugarCRM is to adopt version 3 of the GNU general public license for the next release of its open-source CRM software after coming under pressure from its user community to move away from its own Sugar Public License. 'We just think it's a great license,' said John Roberts, SugarCRM CEO and co-founder. 'It's more copyleft, more liberal and less restrictive than our current license.' He added that when the beta version of Sugar Community Edition 5.0 ships within two weeks, it will be licensed under GPLv3."

+ - Seeing Yellow: fighting printer tracking dots->

Submitted by
jkrobin
jkrobin writes "MIT's Computing Culture research group has established the 'Seeing Yellow' project, which wants to preserve the right to anonymous communication by fighting both printer tracking dots and the government bullying used to sustain them.

We've known for years that color laser printers can embed a series of tiny yellow dots on pages they print. The dots — almost invisible under normal circumstances — can be used to determine which particular printer produced the image. Essentially, each printer outputs its own serial number. This is great for busting counterfeiters but raises all sorts of privacy concerns. Now, MIT students are getting involved in the campaign against the dots with the new Seeing Yellow project.

Imagine that every time you printed a document, it automatically included a secret code that could be used to identify the printer — and potentially, the person who used it. Sounds like something from an episode of "Alias," right?

Unfortunately, the scenario isn't fictional. In a purported effort to identify counterfeiters, the US government has succeeded in persuading some color laser printer manufacturers to encode each page with identifying information. That means that without your knowledge or consent, an act you assume is private could become public. A communication tool you're using in everyday life could become a tool for government surveillance. And what's worse, there are no laws to prevent abuse.

Linux Creator Calls GPLv3 Authors 'Hypocrites' 920

Posted by Zonk
from the family-fued dept.
AlexGr writes "We've heard conflicting tales regarding Linus Torvalds' acceptance of GPLv3. InformationWeek reports on comments by Mr. Torvalds that would seem to decide the issue: 'Torvalds said the authors of a new software license expected to be used by thousands of open source programmers are a bunch of hypocrites ... For Torvalds' part, it appears unlikely he'll ever adopt GPLv3 for the Linux kernel. He accused the Free Software Foundation leadership, which includes eccentric, MIT-trained computing whiz Richard Stallman, of injecting their personal morality into the laws governing open source software with the release of GPLv3. "Only religious fanatics and totalitarian states equate morality with legality," Torvalds wrote.'"

Microsoft "SiteFinder" Quietly Raking It In 176

from the all-your-typos-are-belong-to-us dept.
An anonymous reader writes in with the news, which isn't particularly new, that Microsoft's Internet Explorer sends typo domain names to a page of pay-per-click ads. In this endeavor Microsoft joins Charter and Earthlink in profiting from the dubious practice that Verisign pioneered but failed to make stick. The article is on a site whose audience is, among others, those who attempt to profit by typo-squatting, and its tone is just a bit petulant because individuals cannot hope to profit in this game on the scale Microsoft effortlessly achieves.
