Submission + - Failing students? Change the grade

EvilTwinSkippy writes: "The Philadelphia Inquirer has the story of one principal's crusade to turn a school around. It involved inventing extra paperwork teachers had to file to fail a student. When that failed, she simply went into he computer and changed the grades herself. With No Child Left Behind's emphasis on school performance, you have to wonder how often this is happening and teacher's don't blow the whistle. Especially in lights of the fact that the article mentioned this has happend before, in the same district."

Feed Earth's First Rainforest Unearthed (sciencedaily.com)

A spectacular fossilized forest has transformed our understanding of the ecology of the Earth's first rainforests. Nowhere elsewhere on the planet is it possible to (literally) walk through such an extensive swathe of Carboniferous rainforest.

Submission + - Forget the burger; soon you'll be ordering McWi-Fi

jcatcw writes: From gamers out front to VoIP at the drive-thru, the fast food industry is finally adopting innovative technology. Gamers using Nintendo DS systems currently account for 25% of the Wi-Fi traffic at the 8,000 McDonald's restaurants that offer free Wi-Fi. Voids from incorrect orders dropped by half at Wendy's from broadband and VoIP technology that relays customer orders to a call center. Completed orders are immediately relayed to the store's kitchen order screens and POS station. A digital camera associates an image of the customer and vehicle with each order so that customers are billed correctly and receive the right food.

Submission + - Eat isotopes, live longer...

Roland Piquepaille writes: "This is the promise of a researcher at Oxford University who says that adding natural isotopes to your steak or chicken fillet could increase your life expectancy by 10 years. In 'Meat and two neutrons — the key to a longer life,' the Society of Chemical Industry explains that 'scientists have shown for the first time that food enriched with natural isotopes builds bodily components that are more resistant to the processes of aging.' But I have serious doubts about this claim. First, this experiment has only been done on worms which saw their life spans extended by 10% when exposed to nutrients reinforced with natural isotopes. How can this concept be adapted to us? Then, this research work has been endorsed and published by Aubrey de Grey, the very well-known but controversial gerontologist. But read more for additional references about these questionable additives to our food."

Feed Prior Art On Verizon's VoIP Patents (techdirt.com)

Dan Berninger has been deeply involved in the VoIP world for many years. If you need to know anything about the early days of VoIP, Berninger is worth talking to. These days, he's an analyst for Tier1Research and has just published (and emailed to us) a note looking at the claims in Verizon's VoIP patents that a judge has ruled Vonage infringed on. There are just a few problems with that ruling -- with the key one being that the concepts in those patents were clearly discussed and published by others prior to the patent being filed. Berninger says that the ideas were discussed at the VoIP forum meeting in 1996 and published in January of 1997. The patents in question were filed after that. I've included Berninger's note after the jump. However, due to the fun way the patent system works, introducing that kind of prior art to the USPTO for it to review the validity of Verizon's VoIP patents will take quite a bit of time and effort -- much longer than Vonage has to fight Verizon in court.

Feed What's In The Water? Estrogen-like Chemicals Found In Fish Caught In Pittsburgh' (sciencedaily.com)

A study from the University of Pittsburgh School of Medicine suggests that fish caught in Pittsburgh rivers show evidence of estrogen-like activity, indicating that chemicals that mimic the female hormone may be making their way into the region's waterways. The study also found that when the researchers treated breast cancer cells in culture with fish extracts, the cells grew at increased rates.

Submission + - OLPC operating system available

An anonymous reader writes: DailyTech reports, April 11, 2007, the OLPC folks have released the XO notebook's operating system to the public. The OS has a customized user interface designed to be easier to use and, of course, to fit on the XO laptop's tiny display. A Live CD of the OLPC operating system can be downloaded. The download weighs in at 291MB and is mainly intended for developers, but DailyTech says other curious individuals can also give it a try. For those who'd rather not run the OS on their own system or happen to be out of CD-Rs, screenshots of the XO operating system's user interface and applications can be viewed over at LinuxQuestions.org. The OS reportedly works "remarkably well" on a variety of systems, even though it is designed solely for the XO notebook.

Submission + - Shooting Massacre at Virginia Tech

ConcernedStudent writes: "A violent gunman has apparently unleashed a deadly massacre on the famed science and tech campus, Virginia Polytechnic University (better known as Virginia Tech). The first reports of gunshots were received by police around 7:15 A.M. but shooting continued across the campus for hours longer. Over 25 people are now confirmed dead with many more injured. The shooter appears to have either killed himself or to have been killed by responding police officers. The New York Times has posted front page coverage, and the local Roanoke Times has been providing blog-style coverage, updated regularly.

Feed AACS hacked to expose Volume ID: WinDVD patch irrelevant (engadget.com)

Filed under: Home Entertainment

var digg_url = 'http://digg.com/movies/AACS_hacked_again_to_expos e_Volume_ID_WinDVD_patch_irrelevant'; The DRM "protecting" HD DVD and Blu-ray Disc films -- AACS -- continues to unravel at the seams. In parallel efforts, hackers in both the Xboxhacker and Doom9 forums have exposed the "Volume ID" for discs played on XBOX 360 HD DVD drives. Any inserted disc will play without first authenticating with AACS, even those with Volume IDs which have already been revoked by the AACS LA due to previous hacking efforts. Add the exposed processing keys and you can decrypt and backup your discs for playback on any device of your choosing. So yeah, it looks like last week's WinDVD update has been quickly and definitively made useless just as we expected it would be. Well, for XBOX 360 HD DVD drive owners anyway but you can see where this is heading, right? Now go ahead AACS LA, revoke the Toshiba-built XBOX 360 HD DVD player... we double-dog dare ya.

Submission + - 'Time travel' keeps virtual worlds in sync

space_mongoose writes: New Scientist has a story about a 'time-travel' technique for keeping virtual worlds in synch over the internet. Normally, millisecond delays can build up to create serious discrepancies, but software developed in the UK and US avoids this by constantly checking backwards in time to keep things in sync. It could be especially useful for tele-robotic surgery and other haptic applications.

Submission + - Software Calculator?

An anonymous reader writes: There are simple software calculators like the calc.exe and Abakus and there are more complex/expensive alternatives like matlab and Mathematica. I'm looking for a more friendly and/or more useful software calculator. Not too particular about software licenses or cost, i'm just looking for alternatives. What would you recommend for graphical or text based software calculator?
