World's Newest, Most Powerful Laser Comes Online
deglr6328 writes "The OMEGA EP laser at the University of Rochester's Laboratory for Laser Energetics was dedicated today at the Robert L. Sproull Center for Ultra High Intensity Laser Research. The new laser, which has been in design since ~2002 will, at 1 kilojoule per 1 picosecond pulse, be the highest energy petawatt scale laser ever created by far. For a fleeting fraction of a second, it will deliver a beam of infrared light at 1054 nm that is more powerful than the total energy consumption of all human activity on the planet, to a tiny spot the size of the head of a pin. Previous petawatt scale lasers such as the one created at Lawrence Livermore labs in the late 90's (and dismantled in 1999) were capable of only several hundred joules per pulse. The new OMEGA EP laser will be able to manifest power densities sufficient to examine Unruh and Hawking radiation-like phenomena in the laboratory and will have the capability to directly produce nuclear reactions through ultra high electric field initiated photodisintegration."

The World's Spookiest Weapons
DesScorp writes "Popular Science has a piece on some outrageous ideas for weapons; some came to fruition, and other's didn't. And while some of the weapons (atom bombs, chemical weapons, bats with bombs strapped to them that seek out homes and buildings at night) are truly frightening, some of them are also kind of silly, such as the Gay Bomb, and the Frisbee bomb that was labeled the 'Modular Disc-Wing Urban Cruise Munition.'"

NSF Research Reveals Chain Letter Travel Patterns
alphadogg writes to tell us that the NSF is researching chain letters and how they travel. The results aren't quite what one might expect, showing a pattern of more selective and circuitous travel. "One surprising finding was that messages often took meandering routes between people who knew each other, often through as many as 100 intermediaries. Many email users also received copies from multiple social groups. The researchers concluded that because messages come from many directions, there's ample opportunity for the messages to be edited along the way."

US Senate Asks for National Security Letter Explanation
A group of U.S. Senators are asking the FBI to explain a recent controversial National Security Letter sent to the Internet Archive. The Internet Archive was able to defeat the request with help from the EFF and the ACLU this past April. "The Internet Archive's case is only the third known legal challenge to NSLs, despite the fact that the the FBI issues tens of thousands a year -- more than 100,000 such letters were issued in 2004 and 2005 combined. But despite the lack of legal challenges from recipients at ISPs, telephone companies and credit bureaus, successive scathing reports from the Justice Department's Inspector General have found illegal letters and a willy-nilly culture within the bureau towards tracking their usage."

A Baseball Hat That Reads Your Mind
esocid writes to tell us that researchers from Taiwan have created a new baseball cap complete with embedded -bio-signal monitoring system. The purpose was to give a neural interface that could be useful in everyday life. "The cap contains five embedded dry electrodes on the wearer's forehead, and one electrode behind the left ear, that acquire EEG signals. Then, the EEG signals are wirelessly transmitted to a data receiver, where they are processed in real-time by a dual-core processor. The BCI system includes Bluetooth transmission for distances of 10m or less (e.g., for driving applications), as well as RF transmission for distances up to 600m (e.g., for potential sports applications). Next, the processed signals are transmitted back to the cap, where the data can be stored, displayed in real-time on a screen, or be used to trigger an audio warning, if necessary."

Amputee Sprinter Wins Olympic Appeal to Compete
Dr. Eggman writes "Oscar Pistorius, a 21-year-old South African double-amputee sprinter, has won his appeal filed with the Court of Arbitration for Sport. This overturns a ban imposed by the International Association of Athletics Federations, and allows Mr. Pistorius the chance to compete against other able-bodied athletes for a chance at a place on the South African team for the Beijing Olympics. He currently holds the 400-meter Paralympic world sprinting record, but must improve on his time by 1.01 seconds to meet the Olympic qualification standard. However, even if Pistorius fails to get the qualifying time, South African selectors could add Oscar to the Olympic 1,600-meter relay squad."

Lockheed Martin Awarded GPSIII
D Ninja writes "Yesterday, Lockheed Martin was awarded the $1.4 billion Air Force contract to build the next-generation global positioning satellite system. This occurred after a series of delays as the Air Force decided between Lockheed and the competing bidding contractor, Boeing Co. 'GPS III, will give new navigation warfare (NAVWAR) capabilities to shut off GPS service to a limited geographical location while providing GPS to US and allied forces. GPS III will offer significant improvements in navigation capabilities by improving interoperability and jam resistance. The procurement of the GPS III system is planned for multiple blocks, with the GPS IIIA portion currently underway. GPS IIIA includes all of the GPS IIF capability plus up to a ten-fold increase in signal power, a new civil signal compatible with the European Union's Galileo system, and a new spacecraft bus that will allow a growth path to future blocks.'"

Senators OK $1 Billion for Online Child Porn Fight
A Bill that could allocate more than $1 billion over the next eight years to combat those who trade in child pornography has been unanimously approved by a Senate panel. "The Senate Judiciary Committee on Thursday voted to send an amended version of the Combating Child Exploitation Act, chiefly sponsored by Sen. Joe Biden (D-Del.), to the full slate of politicians for a vote. [...] An amendment adopted Thursday also adds new sections to the original bill that would rewrite existing child pornography laws. One section is designed to make it clear that live Webcam broadcasts of child abuse are illegal, which the bill's authors argue is an "open question." Another change is aimed at closing another perceived loophole, prohibiting digital alteration of an innocent image of a child so that sexually explicit activity is instead depicted."

Shape-Shifting Malware Hits the Web
Stony Stevenson writes to tell us that in a recent interview, Marc Henauer has revealed that security researchers are falling behind now that malware is starting to be able to change its signature every few hours. "Unfortunately the know-how and construction kits used to create this shape-shifting threat are now readily available and are unleashing a wave of malware based on social engineering techniques. [...] Sweeney believes that a non rules-based monitoring process must be set up to defend all ingress and egress points covering SMTP, DNS, HTTP(s), IM etc."

Keeping Customer From Accessing My Database?
cyteen02 writes "We run a data processing and tracking system for a customer in the UK. We provide a simple Web site where the customer can display the tracking data held in our Oracle database. From these screens they can query based on a combination of 15 different data fields, so it's pretty flexible. We also provide a csv report overnight of the previous day's data processing, which they can load into their own SQL Server database and produce whatever reports they want. Occasionally they also want one-off specific detailed reports, so we write the SQL for that and send them the results in an Excel format spreadsheet. This all ticks along happily. However they have now asked for direct read-only access to our Oracle database, to be able to run ad-hoc queries without consulting us. As a DBA, my heart sinks at the thought of amateurs pawing through my database. Unfortunately, 'because you are stupid' is not considered a valid business reason to reject their request. So can any Slashdotters assist me in building my case to restrict access? Have you experienced a similar situation? Have you had to support this sort of end user access? How would you advice me to keep my customer away from my precious tables?"

Honeywell & Airbus To Turn Algae Into Jet Fuel
mystermarque alerts us to an announcement by Honeywell, JetBlue Airways, International Aero Engines, and Airbus about a program to develop jet fuel from algae and other biomass. They hope to supply nearly 1/3 of the demand for jet fuel from these sources by 2030. A Wall Street Journal blog points out that even if this program's goals are met, we will be worse off by 2030 in terms of jet kerosene released into the atmosphere, assuming that the rapid growth in the aviation sector continues apace.

Code Quality In Open and Closed Source Kernels
Diomidis Spinellis writes "Earlier today I presented at the 30th International Conference on Software Engineering a research paper comparing the code quality of Linux, Windows (its research kernel distribution), OpenSolaris, and FreeBSD. For the comparison I parsed multiple configurations of these systems (more than ten million lines) and stored the results in four databases, where I could run SQL queries on them. This amounted to 8GB of data, 160 million records. (I've made the databases and the SQL queries available online.) The areas I examined were file organization, code structure, code style, preprocessing, and data organization. To my surprise there was no clear winner or loser, but there were interesting differences in specific areas. As the summary concludes: '..the structure and internal quality attributes of a working, non-trivial software artifact will represent first and foremost the engineering requirements of its construction, with the influence of process being marginal, if any.'"
