An anonymous reader writes "Researchers at Harvard University and Hamamatsu Photonics have found a way to collimate lasers without lenses. In the new 'plasmonic collimator' technique, grooves are etched directly into the semiconductor laser's internal mirror. This results in surface plasmons giving rise to constructive interference, eliminating the need for the bulky optical lenses that usually focus the light from semiconductor lasers. The technique has promise for steering laser beams without moving parts and for working with polarized light."

theodp writes "CNET reports that Cuil (pronounced 'Cool'), a startup founded by the husband-and-wife team of Xift creator Tom Costello and former Google search architect Anna Patterson, is launching a new search engine today that claims to index three times as many Web pages as Google." Running a few searches left me underwhelmed with the content of the results (hitting the next-page button on a search with a listed 62,200,000 results — for "seattle" — got me the unexpected error message "We didn't find any results for 'seattle.'"), but pleased with the actual layout of the results when it worked, so I hope the kinks are worked out. Update 7/28 18:30 GMT by SM: corrected Tom Costello's accreditation, he wasn't a professor at Stanford as the linked story suggests, just did some research there as a grad student. Thanks to the Stanford CS department for pointing this out.

Anita Kuno writes "JavaScript: The Good Parts is about the good parts of JavaScript and how to use them. This book takes a realistic look at the strengths and weaknesses of JavaScript and tells you how to use it to its best advantage. The code samples deal with the language and its merits — creating web pages is not discussed. How to understand the language, to execute the operations you want, is the focus of the book, not how to make rounded corners. The author, Douglas Crockford says, 'My microwave oven has tons of features, but the only ones I use are cook and the clock. And setting the clock is a struggle. We cope with the complexity of feature-driven design by finding and sticking with the good parts.'" Keep reading for the rest of Anita's review.

Noodlenose notes a thread up on the Ubuntu forums, where a user is questioning the practices of hardware manufacturer Foxconn. The user describes how his new Foxconn motherboard caused his Linux install to freeze and fire off weird kernel errors. He disassembles the BIOS and concludes that a faulty DSDT table is responsible for the errors. Even though the user makes Foxconn aware of the problem, they refuse to correct it, as 'it doesn't support Linux' and is only 'Microsoft certified.' The user speculates darkly on Foxconn's motives. Read the forum, read the code, and come to your own conclusions. "I disassembled my BIOS to have a look around, and while I won't post the results here, I'll tell you what I did find. They have several different tables, a group for Windows XP and Vista, a group for 2000, a group for NT, Me, 95, 98, etc. that just errors out, and one for LINUX. The one for Linux points to a badly written table that does not correspond to the board's ACPI implementation.' The worst part is Foxconn's insistence that the product is ACPI compliant because their tables passed to Windows work, and that Microsoft gave the the magic WHQL certification."

An anonymous reader writes "The University of Michigan Solar Car Team won the 2008 North American Solar Challenge, crossing the finish line in Alberta, Canada on Tuesday after more than 50 hours of racing over nine days. The team successfully defended their title from 2005, the last year the race was held. Final results have been posted on the North American Solar Challenge website and will be officially announced at an award ceremony later today."

Coach Wei writes "Community voting results and a summary report have been published from OpenAjax Alliance's recent "community wishlist for future browsers" effort. When the voting closed on July 13th, 222 people participated in this open community initiative, with 143 people voted, 55 feature requests being written up, and contribution from many industry leaders. The voting indentified and prioritized 37 features. The top 10 are related to vector graphics, security, performance, layout, rich text editing, Comet, audio and video. Among all the feature requests, 2D Drawing/Vector Graphics is clearly the most desired feature by the community. It received most votes (110 people voted for it), and highest total score (over 10% higher than the second feature request). Looks like that it is time for all browsers, in particular, IE, to seriously consider supporting standards-based vector graphics."

chareverie writes "Fortify Software released a study where they concluded that open source software poses a large security risk to corporations who have implemented it. They reason this by stating that the fault lies within the open source communities and their failure to adhere to minimum security practices. Fortify Software studied 11 open source software packages, where the application server Tomcat was determined to be the best. The other 10 were found to have poor results, with those being Derby, Geronimo, Hibernate, Hipergate, JBoss, Jonas, OFBiz, OpenCMS, Resin and Struts. Jacob West, manager of Fortify's research group, reminds that purpose of the study was 'not to condemn open source software, but rather to point out that the security practices need to improve because open source adoption by enterprises and governments is growing.'"

Geoffrey.landis writes "A Purdue University panel investigated allegations against nuclear engineering professor Rusi Taleyarkhan, finding that he had in fact committed scientific misconduct in his work. Taleyarkhan had published papers in which he reported seeing evidence of nuclear fusion in the collapse of tiny bubbles in a liquid subjected to ultrasonic excitation — a finding that would be groundbreaking, if true, but one that apparently could not be replicated by other researchers. The allegations against Taleyarkhan were made in March of 2006. A local Indiana paper gives the full list of allegations against Taleyarkhan, and the resolution of each by the panel. The full report (PDF) is also available. Of the nine specific allegations, only two were found to comprise scientific misconduct. The committee 'could not find any other instances of scientists being able to replicate Taleyarkhan's results without Taleyarkhan having direct involvement with the experiments,' but notes that this comes 'just short of questioning whether Taleyarkhan's results were fraudulent.'" We've discussed this gentleman's work and the scrutiny it has received several times, and members of the scientific community seem to have given him the benefit of the doubt in many cases.

Statesman writes "The Los Angeles Times reports that an Arizona crime lab technician found two felons with remarkably similar genetic profiles, so similar that they would ordinarily be accepted in court as a match, but one felon was black and the other white. The FBI estimated the odds of unrelated people sharing those genetic markers to be as remote as 1 in 113 billion. Dozens of similar matches have been found, and these findings raise questions about the accuracy of the FBI's DNA statistics. Scientists and legal experts want to test the accuracy of official statistics using the nearly 6 million profiles in CODIS, the national system that includes most state and local databases. The FBI has tried to block distribution of the Arizona results and is blocking people from performing similar searches using CODIS. A legal fight is brewing over whether the nation's genetic databases ought to be opened to wider scrutiny. At stake is the credibility of the odds often cited in DNA cases, which can suggest an all but certain link between a suspect and a crime scene."

An anonymous reader writes "Stephen Spoonamore, founder of IT security firm Cybrinth and former advisor to John McCain, claims he has new evidence of election tampering by Diebold in the 2002 Georgia gubernatorial and senate races. A whistleblower gave Spoonamore a patch that was applied to Diebold machines in person by the Diebold CEO. Spoonamore confirmed that the patch did not correct the clock problem it supposedly addressed, but contained two parallel programs. Without access to the hardware, he could not learn more. He reported his findings to the Justice Department, which has not acted."
