Alyssey writes "The Mexican government wants to have a database to track every cellphone number in the country (in Spanish, Google translation) and whom it belongs to. They want to tie in the CURP (Unique Registration Population Code in Spanish, like the Social Security Number in the US) with cellphone numbers. If Mexicans don't send in their number and CURP via SMS before April 10, 2010, their cellphone number will be blocked. The new law was published back in February and is going into effect now."

Miracle Jones writes "As Amazon struggles to re-list and re-rank gay, lesbian, and adult books on their website after massive public outcry against the secretive partitioning process, they are claiming that the entire situation was not the result of an intentional policy at all, are not apologizing, and are instead insisting that the situation was the result of 'a glitch' that they are now trying to fix. While some hackers are claiming credit for 'amazonfail,' and it is indeed possible that an outside party is responsible, most claims have already been debunked. How likely is it that Amazon was hacked versus the likelihood of an internal Easter weekend glitch? Or is the most obvious and likely scenario true, and Amazon simply got caught implementing a wildly-unpopular new policy without telling anyone?"

An anonymous reader writes "ZeroPaid has a fascinating roundup of news stories surrounding the latest surveillance laws passed in India, including a first-hand account of someone writing from inside India. The legislation in question is the Information Technology Act's amendment bill 2006, which was recently passed in the Indian parliament. Things you can't do with the new legislation include surfing for news in Bollywood and looking up porn on the internet. The legislation also allows all transmissions over the internet to be monitored for any form of lawbreaking and permits a sub-inspector to break into your house to make sure you aren't browsing porn on your computer."

An anonymous readerwrites "On Friday the wonderfully customer centric AirTran decided to remove a family of 9 US born Muslims after a comment between two family members regarding how close to the Jet engine they had been seated. The wonderful part is that after the FBI cleared the family 2 hours later, AirTran refused to fly the family, and refused to rebook them on their way from Washington to Orlando, Florida. The family purchased additional tickets on US Airways later that day, after AirTran requested that the irate father be escorted from their booking podiums by security. This whole story highlights the pathetic customer service we are getting from the Airlines these days — they actually treat us like criminals first and ask questions later. Just don't get me started on Delta." It's nice to see that stupidity still knows no bounds.

nandemoari writes "The beta version of Windows 7 has been widely distributed through torrents and other file sharing systems. But now some commentators claim Microsoft deliberately allowed the package to get into the hands of pirates. 'I'm not being critical here, as some Microsoft Watch commenters will surely claim. It's rather smart marketing. Microsoft fills a big news void with something bloggers and journalists will write about. The suspense of stealth downloads from torrents and races to post the best screenshots first make the Windows 7 leak buzz all the more exciting. For other people, there is delight in seeing Microsoft squirm because Seven leaked early. Not that I see much squirming going on.'"

carazoo.com sends along a story on Volvo's upcoming crash-proof car. The company will introduce a concept car based on the S60 this month at the Detroit Auto Show, looking ahead a few years to the goal that by 2020 "no one should be killed or injured in a Volvo car." The concept car will have forward-looking radar as a proximity sensor, and the ability to brake if a collision is imminent. When the car senses a collision, a light flashes on the windscreen display along with an audible warning. If the driver doesn't act, the car will brake automatically.

G'Quann writes "A new survey shows that data retention laws indeed do influence the behavior of citizens (at least in Germany). 11% had already abstained from using phone, cell phone or e-mail in certain occasions and 52% would not use phone or e-mail for confidential contacts. This is the perfect argument against the standard 'I have nothing to hide' argumentation. Surveillance is not only bad because someone might discover some embarrassment. It changes people. 11% at least."

Kligat writes "The COROT project of the French Space Agency has detected an object described as defying categorization as a planet, star, or brown dwarf. Although only 0.8 times the radius of Jupiter, it is over 20 times as massive, giving it a density twice that of the metal platinum. If it is a star, it would be the smallest of those ever discovered."

Coryoth writes "The BBC is reporting on a recent study in the UK that found that the difficulty of high school level math exams has declined. The study looked at mathematics from 1951 through to the present and found that, after remaining roughly constant through the 1970s and 1980s, the difficulty of high school math exams dropped precipitously starting in the early 1990s. A comparison of exams is provided in the appendix of the study. Are other countries, such as the US, noticing a similar decline in mathematics standards?" Readers with kids in school right now may have the best perspective on changes in both teaching and testing methods -- what have you noticed?

Brad Jayakody was told he would have to change his shirt if he wanted to catch his flight to Dusseldorf, Germany. The shirt that security at Heathrow got upset about depicts the Transformers character Optimus Prime holding a gun. Brad said, "I was flabbergasted. I thought the supervisor would come over and see sense, but he didn't. After I changed he said if I changed back I would be arrested." I would understand if the guy was wearing a Megatron shirt, after all that guy turns into a gun which could be very dangerous but Prime? There is no way a semi could fit on a passenger plane it's just silly.

Lisandro sends in news that testing of the new class of superconductors we discussed a while back (compounds of iron, lanthanum, and rare earths) has turned up a major surprise: magnetism doesn't shut off the superconducting state. Magnetic fields represent one of three factors that limit expanded applications for superconductors (the others are current density and temperature dependence.) The research will appear in Nature; here's a preprint (PDF).

An anonymous reader notes that someone has applied the game Six Degrees of Kevin Bacon to the articles in Wikipedia. Instead of the relation being "in the same film," he used "is linked to by." From the blog post: "We'll call the 'Kevin Bacon number' from one article to another the 'distance' between them. It's then possible to work out the 'closeness' of an article in Wikipedia as its average distance to any other article. I wanted to find the centre of Wikipedia, that is, the article that is closest to all other articles (has minimum [distance])."
