Tech Savvy Street Gangs Take On Social Media

 

The fight against Indiana’s gangs isn’t always waged on the street. School officials, social workers and probation officers said the newest battle ground in gang warfare is social media. According to Indianapolis anti-crime advocates who attended a gang awareness seminar on Friday, Indy gang members are younger, more mobile, and they’re using social media networks to recruit and plan. An Indianapolis Metro Police Department gang unit detective said he carries out most of his investigations online and undercover, 6News' Jack Rinehart reported. "I have a Facebook account. My alter-ego has over 210 gang member friends. I have a completely fictitious account,” the IMPD detective said. IMPD have identified more than 300 street gangs in Indianapolis, all of them engaging in various levels of assaults, thefts, robberies and even murder. Lt. Marshall DePew said that because of the gangs’ expansive territory, police have expanded their base of operation, too. "We've expanded our detectives in the unit, and we’ve expanded the number of deputy prosecutors. We have a great liaison with the U.S. attorney’s office. I think more so than ever before, I think we're doing a better job of connecting the dots," DePew said. Police said that every school district in every Indiana county has a gang presence. In Hagerstown in Wayne County, school officials have banned bandannas, sagging pants and cellphone use in school. Officials said they're also contemplating a uniform dress code for students. Dave Land, assistant principal at Hagerstown High School, said he warns parents about the dangers of social media. "I tell parents that if you allow your kids to be on Facebook or do the texting, you're probably going to get into a bullying situation with your son or daughter,” Land said. Police and gang experts agreed that the best deterrent in gang involvement begins at home.

Roll over Einstein: Law of physics challenged

 

One of the very pillars of physics and Einstein's theory of relativity - that nothing can go faster than the speed of light - was rocked Thursday by new findings from one of the world's foremost laboratories. European researchers said they clocked an oddball type of subatomic particle called a neutrino going faster than the 186,282 miles per second that has long been considered the cosmic speed limit.  The claim was met with skepticism, with one outside physicist calling it the equivalent of saying you have a flying carpet. In fact, the researchers themselves are not ready to proclaim a discovery and are asking other physicists to independently try to verify their findings. "The feeling that most people have is this can't be right, this can't be real," said James Gillies, a spokesman for the European Organization for Nuclear Research, or CERN, which provided the particle accelerator that sent neutrinos on their breakneck 454-mile trip underground from Geneva to Italy. Going faster than light is something that is just not supposed to happen according to Einstein's 1905 special theory of relativity - the one made famous by the equation E equals mc2. But no one is rushing out to rewrite the science books just yet. It is "a revolutionary discovery if confirmed," said Indiana University theoretical physicist Alan Kostelecky, who has worked on this concept for a quarter of a century.   Stephen Parke, who is head theoretician at the Fermilab near Chicago and was not part of the research, said: "It's a shock. It's going to cause us problems, no doubt about that - if it's true." Even if these results are confirmed, they won't change at all the way we live or the way the world works. After all, these particles have presumably been speed demons for billions of years. But the finding will fundamentally alter our understanding of how the universe operates, physicists said. Einstein's special relativity theory, which says that energy equals mass times the speed of light squared, underlies "pretty much everything in modern physics," said John Ellis, a theoretical physicist at CERN who was not involved in the experiment. "It has worked perfectly up until now." France's National Institute for Nuclear and Particle Physics Research collaborated with Italy's Gran Sasso National Laboratory on the experiment at CERN. CERN reported that a neutrino beam fired from a particle accelerator near Geneva to a lab 454 miles (730 kilometers) away in Italy traveled 60 nanoseconds faster than the speed of light. Scientists calculated the margin of error at just 10 nanoseconds. (A nanosecond is one-billionth of a second.) Given the enormous implications of the find, the researchers spent months checking and rechecking their results to make sure there were no flaws in the experiment. A team at Fermilab had similar faster-than-light results in 2007, but a large margin of error undercut its scientific significance. If anything is going to throw a cosmic twist into Einstein's theories, it's not surprising that it's the strange particles known as neutrinos. These are odd slivers of an atom that have confounded physicists for about 80 years. The neutrino has almost no mass, comes in three different "flavors," may have its own antiparticle and has been seen shifting from one flavor to another while shooting out from our sun, said physicist Phillip Schewe, communications director at the Joint Quantum Institute in Maryland. Columbia University physicist Brian Greene, author of the book "Fabric of the Cosmos," said neutrinos theoretically can travel at different speeds depending on how much energy they have. And some mysterious particles whose existence is still only theorized could be similarly speedy, he said. Fermilab team spokeswoman Jenny Thomas, a physics professor at the University College of London, said there must be a "more mundane explanation" for the European findings. She said Fermilab's experience showed how hard it is to measure accurately the distance, time and angles required for such a claim. Nevertheless, Fermilab, which shoots neutrinos from Chicago to Minnesota, has already begun working to try to verify or knock down the new findings. And that's exactly what the team in Geneva wants. Gillies told The Associated Press that the readings have so astounded researchers that "they are inviting the broader physics community to look at what they've done and really scrutinize it in great detail, and ideally for someone elsewhere in the world to repeat the measurements." Only two labs elsewhere in the world can try to replicate the work: Fermilab and a Japanese installation that has been slowed by the tsunami and earthquake. And Fermilab's measuring systems aren't nearly as precise as the Europeans' and won't be upgraded for a while, said Fermilab scientist Rob Plunkett. Drew Baden, chairman of the physics department at the University of Maryland, said it is far more likely that the CERN findings are the result of measurement errors or some kind of fluke. Tracking neutrinos is very difficult, he said. "This is ridiculous what they're putting out," Baden said. "Until this is verified by another group, it's flying carpets. It's cool, but ..." So if the neutrinos are pulling this fast one on Einstein, how can it happen? Parke said there could be a cosmic shortcut through another dimension - physics theory is full of unseen dimensions - that allows the neutrinos to beat the speed of light. Indiana's Kostelecky theorizes that there are situations when the background is different in the universe, not perfectly symmetrical as Einstein says. Those changes in background may alter both the speed of light and the speed of neutrinos. But that doesn't mean Einstein's theory is ready for the trash heap, he said. "I don't think you're going to ever kill Einstein's theory. You can't. It works," Kostelecky said. There are just times when an additional explanation is needed, he said. If the European findings are correct, "this would change the idea of how the universe is put together," Columbia's Greene said. But he added: "I would bet just about everything I hold dear that this won't hold up to scrutiny."

Millions of Hotmail users cut off by Microsoft 'cloud' failure

 

As well as Hotmail, the outage affected Office 365 and the Skydrive online storage service. Microsoft said the cause appeared to be related to the Domain Name System, the computer network that ensures that web addresses are connected to websites. “Preliminary root cause suggests a DNS issue,” the firm said on its office 365 Twitter feed. The problems lasted for at least two-and-a-half hours, beginning at around 4AM British Summer Time. On a company blog, Microsoft said it had fixed the problem at 5.45AM, but the repairs took some time to “propagate” through the DNS network.  "We are working on propagating the DNS configuration changes and so it will take some time to restore service to everyone. Again we appreciate your patience," the firm said. For Office 365, Microsoft’s subscription-only competitor to Google Apps, which went live earlier this year, it was the second major technical failure in less than a month. Such incidents are likely to give pause to organisations considering migration to online “cloud” services, whereby software is delivered from vast data centres, over the internet.

Starting today, companies and celebrities will have a 50-day "sunrise" period allowing them to officially register under the .xxx domain and put down bids to set up shop in the Internet's red-light district.

 

The new .xxx top-level domain is open not just to porn sites but to nonporn sites that want to block the use of their names on the .xxx domain. Florida-based ICM Registry, which is administering the launch, will work with 50 individual registrars around the world to handle the actual registrations. After the expiration of the sunrise period, a 17 day "land rush" period will open, allowing adult sites to register for whatever .xxxx addresses are still available. After that, applications will be reviewed individually on a first come basis.
