Record-Breaking Solar Cells are Tailored to Their Location

The burning hot sun at the equator is a far cry from the weak sunlight that reaches higher latitudes. To make the most of such different conditions you need specially tailored solar cells, according to UK firm Quantasol. So the company has come up with a new solar cell design that can be tuned to the light at a particular latitude, and in the process broken a 21-year-old efficiency record for one type of solar cell

NSA to Build Huge Facility in Utah

Hoping to protect its top-secret operations by decentralizing its massive computer hubs, the National Security Agency will build a 93,000m² data centre at Utah’s Camp Williams. The years-in-the-making project, which may cost billions over time, got a $181 million start last week when President Obama signed a war spending bill in which Congress agreed to pay for primary construction, power access and security infrastructure. The enormous building, which will have a footprint about three times the size of the Utah State Capitol building, will be constructed on a 200-acre site near the Utah National Guard facility’s runway

Optus Confirms Launch of D3 Bird

Optus today confirmed it will launch its D3 satellite, which will be used to provide more pay-TV channels, in mid-August. The director of Optus Satellite Paul Sheridan said the new satellite will significantly increase its capacity. Foxtel will be the largest customer of the new satellite, which will carry its new suite of HD pay-TV and other channels. Foxtel has previously said it intends launching more than 20 new channels this year

Email Patterns Can Predict Impending Doom

Email logs can provide advance warning of an organisation reaching crisis point. That’s the tantalising suggestion to emerge from the pattern of messages exchanged by Enron employees. After US energy giant Enron collapsed in December 2001, federal investigators obtained records of emails sent by around 150 senior staff during the company’s final 18 months. The logs, which record 517,000 emails sent to around 15,000 employees, provide a rare insight into how communication within an organisation changes during stressful times

Firefox 3.5 Now Available

Mozilla fired another shot in the browser wars today with the release of Firefox 3.5. The browser, which was previewed before going to the Release Candidate stage, was driven by quality instead of a timeline, according to the company. The focus for this version of Firefox is speed. Vlad Vukicevic, tech lead for the Firefox project at Mozilla, says that the main significance [of the browser upgrade] is that Firefox 3.5 is really, really fast. Aside from the speed boost, Firefox 3.5 also boasts HTML 5 capabilities for handling audio and video, and a JavaScript performance and stability boost courtesy of the TraceMonkey JavaScript engine

Amazon Cuts Rhode Island Partners Over Tax

Amazon cut ties today with its business affiliates in Rhode Island to protest a provision in the draft state budget that would force the company to collect sales tax. Rhode Island is now the second state where affiliates in the program, known as Amazon Associates, have been cut off over the sales tax issue. Earlier this month the Seattle-based online retailer also closed its affiliates’ accounts in North Carolina

‘Life or Death’ SPASMS Alert

The communications regulator has sounded the alarm after receiving a number of complaints from Australians who received SMS messages containing death threats. The threats, which tell the victim I am about to kill you unless they contact an email address, are part of an SMS scam campaign designed to con targets out of personal details, cash and passwords. The warning from the Australian Communications and Media Authority (ACMA) today comes after this website reported yesterday how scores of Australians had received SMS spam messages saying they have won $123,000, but must reply with their email address for instructions on how to claim the prize. The campaign is a ruse, attempting to trick people into paying $1000 for courier fees in order to claim a non-existent prize

FFSearcher: A Stealthy Evolution in Click Fraud

A new Trojan horse program being distributed by tens of thousands of recently hacked Web sites hijacks search results so that Google.com users can scarcely tell that their Web searches are being funneled through third-party sites. Earlier this month, security experts at Websense warned that some 40,000 Web sites were hacked and seeded with code that bombards a visitor’s PC with a virtual kitchen sink worth of browser exploits, all in an effort to install a Trojan horse program. Websense named this mass compromise Nine-Ball, and the Trojan dropped on victimized PCs was thought to install a range of malicious software

Spam Blacklist Bids Top $1m

One of the largest spam blacklists in the world, developed in Australia, is up for sale and the creator has already received offers of more than $1 million. Proposals have come from all over the world and dubious organisations have been especially keen on the acquisition. The list, popularly known as SORBS or spam and open relay blocking system, was created in 2002 by programmer Michelle Sullivan (then known as Matthew Sullivan), who used to work at the University of Queensland. SORBS is a free service that sets up virtual spam traps to identify and block senders of unsolicited bulk email

Senators Want to Bar Contracts to Foreign Companies Selling IT to Iran

Two senators plan to introduce a bill that would bar foreign companies that sell technology to Iran from receiving federal contracts. Senators Charles Schumer, D-NY, and Lindsey Graham, R-SC, said they wrote up the legislation after the Wall Street Journal reported on June 22 that a joint venture of Nokia of Finland and Siemens AG of Germany had sold a sophisticated Internet-monitoring system to Iran in 2008. Schumer and Graham’s bill would require the Obama administration to identify foreign companies that export sensitive technology to Iran and ban them from bidding on federal contracts, or renew expiring ones, unless they first stop exports to Iran

China Limits Use Of Virtual Currency

Trading virtual currency for real goods has been banned in China, putting hundreds of millions of dollars in economic activity at risk. In addition to its ongoing crackdown on Internet porn, the Chinese government has declared that virtual currency cannot be traded for real goods or services. Virtual currency, as defined by Chinese authorities, includes prepaid cards of cyber-games, according to a joint release issued by China’s Ministry of Culture and Ministry of Commerce on Friday

Britain Hires Hacker to Held Defend the Realm

Britain is hiring former computer hackers to join a new security unit aimed at protecting cyberspace from foreign spies, thieves and terrorists, the country’s terrorism minister said. Alan West said the technology-savvy staff would join efforts to trace the source of — and prevent — cyber attacks on Britain’s government, businesses and individuals. The country also will develop its capability to wage cyber warfare against the country’s foes, he said

Feathered Fuel Tank Soaks Up Hydrogen

The gas tank of the future may be full of chicken feathers. Engineers have discovered a way to store large amounts of hydrogen fuel using carbonised downy fluff, which could help pave the way to clean, green cars. A practical hydrogen car has been elusive for decades. Before the announcement this week by University of Delaware engineers, a nonstop trip from Portland to Eugene in a hydrogen car would need a tank bigger than 100 gallons to store liquid or gaseous fuel, even under high pressure. Treated chicken feathers work like a sponge. They soak up large amounts of hydrogen and hold it in a small space so the tank can be a conventional size and the fuel won’t need to held under dangerously high pressures. Hydrogen creates only water vapor when it burns, unlike gasoline that emits carbon dioxide, a culprit in climate change

Glitch Snarls CBA’s Online Bank

Commonwealth Bank’s web banking service NetBank failed today, in what could be a hacker attack, leaving thousands of customers unable to access their accounts via the internet. A recorded message on the bank’s phone access line acknowledged the problem with NetBank, saying it was working to resolve this as a matter of emergency. The bank blamed intermittent network issues and gave no set time for the entire system to be restored

Keeping News of Kidnapping Off Wikipedia

For seven months, The New York Times managed to keep out of the news the fact that one of its reporters, David Rohde, had been kidnapped by the Taliban. But that was pretty straightforward compared with keeping it off Wikipedia. Times executives believed that publicity would raise Mr Rohde’s value to his captors as a bargaining chip and reduce his chance of survival. Persuading another publication or a broadcaster not to report the kidnapping usually meant just a phone call from one editor to another, said Bill Keller, executive editor of The Times. But Wikipedia, which operates under the philosophy that anyone can be an editor, and that all information should be public, is a vastly different world. A dozen times, user-editors posted word of the kidnapping on Wikipedia’s page on Mr Rohde, only to have it erased. Several times the page was frozen, preventing further editing — a convoluted game of cat-and-mouse that clearly angered the people who were trying to spread the information of the kidnapping. Even so, details of his capture cropped up time and again, however briefly, showing how difficult it is to keep anything off the Internet — even a sentence or two about a person who is not especially famous. The sanitising was a team effort, led by Jimmy Wales, co-founder of Wikipedia, along with Wikipedia administrators and people at The Times. In an interview, Mr Wales said that Wikipedia’s cooperation was not a given. We were really helped by the fact that it hadn’t appeared in a place we would regard as a reliable source, he said. I would have had a really hard time with it if it had
