pinkstuff writes "The Navy unveiled its terror-fighting marine mammals at a two-day homeland security and disaster preparedness exercise in California this week. From the article: 'A Navy seal — actually a sea lion — took less than a minute to find a fake mine under a pier near San Francisco's AT&T Park. A dolphin quickly located a terrorist lurking in the black water before another sea lion, using a device carried in its mouth, cuffed the pretend saboteur's ankle so authorities could reel him in.' Queue the 'frickin lasers' jokes."

An anonymous reader writes "Web browser history detection with the CSS:visited trick has been known for the last ten years, but recently published research suggests that the problem is bigger than previously thought. A study of 243,068 users found that 76% of them were vulnerable to history detection by malicious websites. Newer browsers such as Safari and Chrome were even more affected, with 82% and 94% of users vulnerable. An average of 63 visited locations were detected per user, and for the top 10% of users the tests found over 150 visited sites. The website has a summary of the findings; the full paper (PDF) is available as well."

alphadogg writes "Even without cookies, popular browsers such as Internet Explorer and Firefox give websites enough information to get a unique picture of their visitors about 94 percent of the time, according to research compiled over the past few months by the Electronic Frontier Foundation. [The Research] puts quantitative assessment on something that security gurus have known about for years, said Peter Eckersley, the EFF senior staff technologist who did the research. He found that configuration information — data on the type of browser, operating system, plugins, and even fonts installed — can be compiled by websites to create a unique portrait of most visitors. This means that most Internet users are a lot less anonymous than they believe, Eckersley said. 'Even if you turn off cookies and you use a proxy to hide your IP address, you could still be tracked,' he said."

ubermiester writes "The New York Times is reporting that scientists at Fermilab have found evidence of a very small (about 1%) average difference between the amount of matter/antimatter produced in a series of particle collisions. Quoting: '[T]he team, known as the DZero collaboration, found that the fireballs produced pairs of ... muons ... slightly more often than they produced pairs of anti-muons. So the miniature universe inside the accelerator went from being neutral to being about 1 percent more matter than antimatter.' This finding invites theorists to explain why there is so much more matter than antimatter in the universe, when the Standard Model suggests that there should be equal amounts of each." Here is the paper as submitted to Physical Review (PDF). The DZero team is looking forward to getting detailed data from the LHC once it ramps up operationally.

bgsneeze writes "In order to resolve an ongoing issue with a vendor, I have been trying to find a way to test different 3G data devices empirically. I would like to be able to chart signal strength, latency, and bandwidth. I would also like to create a map of the coverage area. I have a test 3G card from three different providers. I would like to be able to travel with the setup to several different locations and run tests. What software or techniques would Slashdotters use to test the different devices? Are there any free or open source software packages that will do this?"

KentuckyFC writes "Any proof that quantum cryptography is perfect relies on idealized assumptions that don't always hold true in the real world. One such assumption is related to the types of errors that creep into quantum messages. Alice and Bob always keep a careful eye on the level of errors in their messages because they know that Eve will introduce errors if she intercepts and reads any of the quantum bits in a message. So a high error rate is a sign that the message is being overheard. But it is impossible to get rid of errors entirely, so Alice and Bob have to tolerate a small level of error. This level is well known. Various proofs show that if the quantum bit error rate is less than 20 percent, then the message is secure. However, these proofs assume that the errors are the result of noise from the environment. Now, physicists have come up with an attack based on the realization that Alice also introduces errors when she prepares the required quantum states to send to Bob. This extra noise allows Eve to intercept some of the quantum bits, read them and then send them on, in a way that raises the error rate to only 19.7 percent. In this kind of 'intercept and resend attack,' the error rate stays below the 20 percent threshold and Alice and Bob are none the wiser, happily exchanging keys while Eve listens in unchallenged. The physicists say they have successfully used their hack on a commercial quantum cryptography system from the Geneva-based startup ID Quantique."

greenrainbow writes "Today a team of researchers at MIT unveiled their design for an airplane that uses 70% less fuel than conventional aircraft. The MIT design comes thanks to a NASA-funded initiative to increase fuel efficiency, lower emissions, and allow planes to take off on shorter runways. The team accomplished all of NASA's set goals with their innovative D-series plane, lovingly referred to as the 'double bubble,' which has thinner, longer wings and a smaller tail, and engine placement at the rear of the plane instead of on the wings."

The ACLU is suing the police in Pennsylvania for issuing tickets to people who swear. They argue that it is every American's constitutional right to drop an F-bomb. From the article: "'Unfortunately, many police departments in the commonwealth do not seem to be getting the message that swearing is not a crime,' said Marieke Tuthill of the ACLU of Pennsylvania. 'The courts have repeatedly found that profanity, unlike obscenity, is protected speech.'" This is a big f*cking deal.

ZDOne writes "Small and inexpensive notebooks have been a hot topic in recent months as the Classmate, XO laptop, and the Asus Eee go head-to-head with each other for the low end/educational market. ZDNet has a look at all three systems, comparing the three platforms on multiple points of data to determine which of the three fits your needs. 'In terms of overall stylishness the Eee is the winner, but the XO and the Classmate are both more rounded and rugged, and come with carrying handles. The OLPC XO has the biggest screen, an innovative 7.5in. dual-mode transmissive/reflective LCD that can swivel from traditional clamshell mode to 'e-book' mode with the screen facing outwards, tablet-style (although it's not a touch-screen). The Classmate and Eee both have similar, rather cramped, 7in. TFT displays. '"

jason writes "YouTube has never really been known for streaming videos at a high resolution, but it appears that they are taking early steps at providing higher quality videos. The project was announced last year by the site's co-founder Steve Chen, and now appears to be in the earliest stages of deployment. By adding a parameter onto the end of a video's URL you're able to watch it in a higher quality (in terms of audio and video) that is actually quite noticeable. Not all videos have been converted at this point, but they do have millions upon millions of videos that they need to do."

An anonymous reader writes "Convinced the current music business infrastructure (requiring artists to rely on labels) is broken, Nine Inch Nails front man, Trent Reznor, released his band's new album, Ghosts I — IV (Ghosts Volumes One though Four), on Sunday at 6 PM via his official site, marking yet another business experiment for this artist in the changing music market."

Ian Lamont writes "Telcos, ISPs, mobile phone companies and other communication service providers are known for their complex pricing plans and creative attempts to give less for more. But Larry Borsato asks why we as customers are willing to put up with anything less than 99.999% uptime? That's the gold standard, and one that we are used to thanks to regulated telephone service. When it comes to mobile phone service, cable TV, Internet access, service interruptions are the norm — and everyone seems willing to grin and bear it: 'We're so used cable and satellite television reception problems that we don't even notice them anymore. We know that many of our emails never reach their destination. Mobile phone companies compare who has the fewest dropped calls (after decades of mobile phones, why do we even still have dropped calls?) And the ubiquitous BlackBerry, which is a mission-critical device for millions, has experienced mass outages several times this month. All of these services are unregulated, which means there are no demands on reliability, other than what the marketplace demands.' So here's the question for you: Why does the marketplace demand so little when it comes to these services?"
