TV White Space & The Future of Wireless Broadband 119

DeviceGuru writes "The unoccupied radio spectrum between broadcast TV channels may soon become a source of low-cost, ubiquitous broadband connectivity. Earlier this month, the U.S. Federal Communications Commission began Phase II testing of 'white space device' prototypes, to determine whether WSDs can operate without interfering with the other wireless devices commonly used in homes, offices, and public locations. A key advantage of white space wireless technology, compared to the combination of WiFI and WiMAX, is its TV-like ability to cover broad areas and penetrate walls and trees, using relatively low power levels."

Submission + - SPAM: IRS information security still hurting

alphadogg writes: The Internal Revenue Service continues to have "pervasive" information security weaknesses that put taxpayer information at risk, and it has made limited progress in fixing dozens of problems the U.S. Government Accountability Office has previously identified, according to a GAO report released Tuesday. The IRS, the tax-collecting arm of the U.S. government, has "persistent information security weaknesses that place [it] at risk of disruption, fraud or inappropriate disclosure of sensitive information," the GAO report said. The agency, which collected about US$2.7 trillion in taxes in 2007, has fixed just 29 of 98 information security weaknesses identified in a report released last March, the new report said.

Submission + - Negroponte slams Intel over OPLC

Stony Stevenson writes: Nicholas Negroponte, the founder of the One Laptop Per Child (OLPC) project, has slammed Intel for its conduct. In this article from iTnews, Negroponte accused the chip giant of joining the project late, continually running it down to others and not pulling its weight. Negroponte maintained that Intel had contributed nothing to the project, and caused considerable harm to efforts to deliver XO laptops to the developing world.

From the article: "We at OLPC have been disappointed that Intel could not deliver on any of the promises they made when they joined OLPC. While we were hopeful for a positive, collaborative relationship, it never materialised," he said. ""Actions do speak louder than words in this case. As we said in the past, we view the children as a mission; Intel views them as a market."

Submission + - Switchgrass Ethanol produces 540% energy gain. 1

Gibbs-Duhem writes: BBC News is reporting on the first large-scale study of cellulosic ethanol using actual measured values from a 5-year study involving ten farms from three to nine hectares. The results show that ethanol derived from switchgrass contain approximately 540% more energy than is needed to produce it. Switchgrass and other fast growing crops are very attractive for cellulosic ethanol production because, unlike corn or other food crops, the entire plant is used.

The study includes real measured values for fertilizer, diesel fuel for transport, fuel used for seed production, and herbicides. The remaining energy input to be measured is the efficiency of the actual biorefineries which would convert the switchgrass cellulose to ethanol, so the study was forced to estimate those values. The numbers for that stage of the process are due out soon, with six refineries scheduled to be opened by 2010 which are "above the pilot plant scale."

Submission + - Sight for the blind.

Manifold Space Traveler writes: "The primary problem with this technology is that the neural pathways are set at an early age and the mind is not like a hard disk, you cannot simply erase a lifetime of experience and then reinstall linux. Existing research seems to indicate that late acquired sight adversely affects the mind so much, that it leads to depression and in some cases suicide. This technology is several years old and is not "news" at all."

Submission + - General Aviation System in Jeopardy

robwmc writes: I'm not sure how many here on /. are pilots but the Bush administration evidently want to make that number decline. The new budget calls for charging user fees for access to airspace, raising the aviation fuel tax to $0.70 per gallon and raising fees for everything related to being a GA pilot. Take a look at one of the various articles on the AOPA website.

The AOPA has worked very hard for keeping the system "fair" for the average Joe to keep the cost of flying affordable for the general public.

Submission + - Interview: oldschool BSD hacker Sam Leffler

An anonymous reader writes: In this interview, Sam Leffler, current director of the FreeBSD Foundation and one of the UC Berkeley CSRG hackers who worked on the original BSD operating system, talks about what the Foundation does, upcoming networking features in FreeBSD, and how Apple contributes to the team's work.

Submission + - More Martian Water Evidence

tubapro12 writes: NASA's Mars Reconnaissance Orbiter has detected light-toned bedrock on Mars occurring in an alternating pattern with darker bedrock within a rift valley. Researchers at the University of Arizona point to this as a product of a liquid, probably water, passing through the rocks.

"On Earth, bleaching of rock surrounding a fracture is a clear indication of chemical interactions between fluids circulating within the fracture and the host rock," Okubo and co-author Alfred S. McEwen reported in the paper. The researchers also said that layered outcrops can indicate cycles with materials deposited by regular episodes of water, wind or volcanic activity.

Scientists Dubious of Quantum Computing Claims 107

Dollaz wrote with a link to the International Business Times, which questions the authenticity of D-Wave's Quantum computing. We discussed the 'Sudoku playing' computer yesterday, but scientists in the field have expressed a lot of distrust of the company's findings. The machine was not available for inspection during or after the demo, and even if the technology was working as intended there is some doubt that it can be scaled. The article points out that "notwithstanding lofty claims in the company's press release about creating the world's first commercial quantum computer, D-Wave Chief Executive Herb Martin emphasized that the machine is not a true quantum computer and is instead a kind of special-purpose machine that uses some quantum mechanics to solve problems." Good to see people in the field questioning 'breakthroughs'.
Programming

Submission + - How do you hire a programmer if you're not one?

NewMediaBlogger writes: "I'm a geeky business guy — I know basic SQL/Linux/PHP, but am definitely not a programmer. I have a software idea I want to develop, but am not confident enough in my own skills to determine whether or not a programmer is "good". I don't know a elite programmer I can hire to build a team for me.
How do you judge a programmer if you are not one yourself?
Is there an external consulting service you use? Skill testing in the interview process? "Trial" work contracts? Other?"

Journal Journal: Music execs criticise DRM systems

Almost two-thirds of music industry executives think removing digital locks from downloadable music would make more people buy the tracks, finds a survey.

Haha.

Congress Tackles Patent Reform 261

nadamsieee writes "Wired's Luke O'Brian recently reported about Congress' latest attempt to reform the patent system. In the article O'Brian tells of how 'witnesses at Thursday's hearing painted a bleak picture of that system. Adam Jaffe, a Brandeis University professor and author of a book on the subject, described the system as 'out of whack.' Instead of 'the engine of innovation,' the patent has become 'the sand in the gears,' he said, citing widespread fears of litigation. The House Oversight Committee website has more details. How would you fix the patent system?"

Submission + - Smokers may be the weak IT security link

BobB writes: "Where there's smoke, there's a door. A U.K. security company is warning that smokers may impact IT security, leaving open doors that could let in intruders who could abuse a company's network. It may sound slightly far-fetched. But a penetration tester from NTA Monitor Ltd., a company based in Rochester, England, gained access to a professional services company outside London that way. http://www.networkworld.com/news/2007/021607-smoke rs-may-be-the-weak.html"
