Geographic Segregation By Education 99

The wage gap between college-educated workers and those with just a high school diploma has been growing — and accelerating. But the education gap is also doing something unexpected: clustering workers with more education in cities with similar people. "This effectively means that college graduates in America aren't simply gaining access to higher wages. They're gaining access to high-cost cities like New York or San Francisco that offer so much more than good jobs: more restaurants, better schools, less crime, even cleaner air." Most people are aware of the gentrification strife occurring in San Francisco, but it's one among many cities experiencing this. "[Research] also found that as cities increased their share of college graduates between 1980 and 2000, they also increased their bars, restaurants, dry cleaners, museums and art galleries per capita. And they experienced larger decreases in pollution and property crime, suggesting that cities that attract college grads benefit from both the kind of amenities that consumers pay for and those that are more intangible." The research shows a clear trend of the desirable cities becoming even more desirable, to the point where it's almost a necessity for city planners to lure college graduates or face decline.

An anonymous reader writes "O3b Networks is aiming to provide internet access through satellite, to the "other three billion" people in under-served equatorial regions (Africa, the Pacific, South America). O3b launched four more satellites today, to add to the four they already have in orbit. This is a very international effort; a Russian Soyuz rocket went up from South America, carrying satellites built in France. There's a video of the rocket and payloads coming together and a video of the rocket launch. There's also an academic paper describing using the O3b system from the Cook Islands in the Pacific, giving an idea of what it does and those all-important ping times."

MojoKid writes: "When NSA whistleblower Edward Snowden came forth last year with U.S. government spying secrets, it didn't take long to realize that some of the information revealed could bring on serious repercussions — not just for the U.S. government, but also for U.S.-based companies. The latest to feel the hit? None other than Apple, and in a region the company has been working hard to increase market share: China. China, via state media, has today declared that Apple's iPhone is a threat to national security — all because of its thorough tracking capabilities. It has the ability to keep track of user locations, and to the country, this could potentially reveal "state secrets" somehow. It's being noted that the iPhone will continue to track the user to some extent even if the overall feature is disabled. China's iPhone ousting comes hot on the heels of Russia's industry and trade deeming AMD and Intel processors to be untrustworthy. The nation will instead be building its own ARM-based "Baikal" processor.

itwbennett writes: The Federal Communications Commission, in a 3-2 party-line vote Friday, approved a plan to revamp the 17-year-old E-Rate program, which pays for telecom services for schools and libraries, by phasing out funding for voice service, Web hosting and paging services, and redirecting money to Wi-Fi. FCC Chairman Tom Wheeler had proposed a $5 billion budget for Wi-Fi, but Republican commissioners and some lawmakers had questioned where the money would come from. Still, the E-Rate revamp (PDF) approved Friday contemplates a $1 billion-a-year target for Wi-Fi projects "year after year," Wheeler said.

DARPA Successfully Demonstrates Self-Guiding Bullets 169

Lucas123 writes: A DARPA-funded project has successfully developed a .50 caliber sniper round capable of maneuvering during flight in order to remain on target. The self-guiding EXACTO bullet, as it's being called, is optically guided by a laser that must remain on target for the bullet to track. The EXACTO round is capable of accurately tracking a target up to 1.2 miles away, DARPA stated. The technology, which is being developed by Teledyne Scientific and Imaging, is targeted at helping snipers remain at longer distances from targets as well as improving night shots. While DARPA's tracking bullet is the first to use a standard, small-arms caliber round, in 2012 Sandia National Laboratories (SNL) successfully demonstrated a prototype self-guided bullet that was more like like a four-inch dart.

A Peek Inside D-Wave's Quantum Computing Hardware 54

JeremyHsu writes: A one-second delay can still seem like an eternity for a quantum computing machine capable of running calculations in mere millionths of a second. That delay represents just one of the challenges D-Wave Systems overcame in building its second-generation quantum computing machine known as D-Wave Two — a system that has been leased to customers such as Google, NASA and Lockheed Martin. D-Wave's rapid-scaling approach to quantum computing has plenty of critics, but the company's experience in building large-scale quantum computing hardware could provide valuable lessons for everyone, regardless of whether the D-Wave machines live up to quantum computing's potential by proving they can outperform classical computers. (D-Wave recently detailed the hardware design changes between its first- and second-generation quantum computing machines in the the June 2014 issue of the journal IEEE Transactions on Applied Superconductivity.)

"We were nervous about going down this path," says Jeremy Hilton, vice president of processor development at D-Wave Systems. "This architecture requires the qubits and the quantum devices to be intermingled with all these big classical objects. The threat you worry about is noise and impact of all this stuff hanging around the qubits. Traditional experiments in quantum computing have qubits in almost perfect isolation. But if you want quantum computing to be scalable, it will have to be immersed in a sea of computing complexity.

The First Person Ever To Die In a Tesla Is a Guy Who Stole One 414

mrspoonsi sends this news from The Verge: Elon Musk can no longer say that no one's ever died in a Tesla automobile crash. But few people will be pointing fingers at the electric car maker for this senseless tragedy. Earlier this month, 26-year-old Joshua Slot managed to successfully ride off with a Model S he'd stolen from a Tesla service center in Los Angeles, but police quickly spotted the luxury vehicle and gave chase. According to Park Labrea News, the high-speed pursuit was eventually called off after officers were involved in a fender bender of their own, leaving the police department strained for resources and without any feasible way of catching up to Slot. Reports claim he was traveling at speeds of "nearly 100 mph," but losing the police tail apparently didn't convince Slot to hit the brakes. Instead he sped on, eventually colliding with three other vehicles and a pair of street poles. The final impact was severe enough to "split the Tesla in half" and eject Slot from the car's remains. The Tesla's front section wound up in the middle of the road and caught fire. Its rear portion flew through the air with such force that it slammed into the side of a local Jewish community center and became wedged there.

William Binney: NSA Records and Stores 80% of All US Audio Calls 272

Posted by Soulskill
from the must-use-a-good-compression-algorithm dept.
stephendavion sends a report at The Guardian about remarks from whistleblower William Binney, who left the NSA after its move toward overreaching surveillance following the September 11th attacks. Binney says, "At least 80% of all audio calls, not just metadata, are recorded and stored in the U.S. The NSA lies about what it stores." He added, "The ultimate goal of the NSA is total population control, but I’m a little optimistic with some recent Supreme Court decisions, such as law enforcement mostly now needing a warrant before searching a smartphone." One of Binney's biggest concerns about government-led surveillance is its lack of oversight: "The FISA court has only the government’s point of view. There are no other views for the judges to consider. There have been at least 15-20 trillion constitutional violations for U.S. domestic audiences and you can double that globally."

Gameover ZeuS Re-Emerges As Fast-Fluxing Botnet 49

New submitter tylke (621801) writes: "Brian Krebs is reporting that the Gameover ZeuS botnet recently taken down by the U.S. Justice Department in June has re-emerged. The new variant of the Trojan is "stripped of the P2P code, and relies instead on an approach known as fast-flux hosting," a kind of round-robin technique that lets botnets hide phishing and malware delivery sites behind a network of compromised systems. Krebs says, "[T]his variant also includes a 'domain name generation algorithm' or DGA, which is a failsafe mechanism that can be invoked if the botnet’s normal communications system fails. The DGA creates a constantly-changing list of domain names each week (gibberish domains that are essentially long jumbles of letters). In the event that systems infected with the malware can’t reach the fast-flux servers for new updates, the code instructs the botted systems to seek out active domains from the list specified in the DGA. All the botmasters need to do in this case to regain control over his crime machine is register just one of those domains and place the update instructions there." (Disclosure: I work for Malcovery Security, the company credited with identifying the new variant.)

Arecibo Radio Telescope Confirms Extra-galactic Fast Radio Pulses 93

from the Romulan-morse-code dept.
schwit1 writes: "The Arecibo radio telescope has confirmed the existence of fast radio pulses. "Fast radio bursts (FRBs) are bright flashes of radio waves that last only a few thousandths of a second. Scientists using the Parkes Observatory in Australia recorded such events for the first time, but the lack of any similar findings by other facilities led to speculation that the Australian instrument might have been picking up signals originating from sources on or near Earth. The discovery at Arecibo is the first detection of a fast radio burst using an instrument other than the Parkes radio telescope. The position of the radio burst is in the direction of the constellation Auriga in the Northern sky.

"Our result is important because it eliminates any doubt that these radio bursts are truly of cosmic origin," continues Victoria Kaspi, an astrophysics professor at McGill University in Montreal and Principal Investigator for the pulsar-survey project that detected this fast radio burst. "The radio waves show every sign of having come from far outside our galaxy – a really exciting prospect." Exactly what may be causing such radio bursts represents a major new enigma for astrophysicists. Possibilities include a range of exotic astrophysical objects, such as evaporating black holes, mergers of neutron stars, or flares from magnetars — a type of neutron star with extremely powerful magnetic fields." Be warned: All of the above theories could also be wrong. These fast radio flashes could just as easily turn out to be something entirely unpredicted.
