A Peek Inside D-Wave's Quantum Computing Hardware

Soulskill posted 17 minutes ago | from the hamsters-are-neither-alive-nor-dead dept.

Supercomputing 1

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

Transportation 109

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

Privacy 103

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

Botnet 24

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

Soulskill posted 3 hours ago | from the Romulan-morse-code dept.

Space 69

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.

Ask Slashdot: Unattended Maintenance Windows?

IT 187

grahamsaa writes: Like many others in IT, I sometimes have to do server maintenance at unfortunate times. 6AM is the norm for us, but in some cases we're expected to do it as early as 2AM, which isn't exactly optimal. I understand that critical services can't be taken down during business hours, and most of our products are used 24 hours a day, but for some things it seems like it would be possible to automate maintenance (and downtime).

I have a maintenance window at about 5AM tomorrow. It's fairly simple — upgrade CentOS, remove a package, install a package, reboot. Downtime shouldn't be more than 5 minutes. While I don't think it would be wise to automate this window, I think with sufficient testing we might be able to automate future maintenance windows so I or someone else can sleep in. Aside from the benefit of getting a bit more sleep, automating this kind of thing means that it can be written, reviewed and tested well in advance. Of course, if something goes horribly wrong having a live body keeping watch is probably helpful. That said, we do have people on call 24/7 and they could probably respond capably in an emergency. Have any of you tried to do something like this? What's your experience been like?

Amazon Seeks US Exemption To Test Delivery Drones

Government 117

angry tapir writes: Amazon.com has asked the U.S. Federal Aviation Administration for permission to test drones outdoors for use in its Prime Air package delivery service. In the run up to launching the service, which aims to deliver packages in 30 minutes or less, the online retailer is developing aerial vehicles that travel over 50 miles (80 kilometers) per hour, and will carry 5pound (2.3 kilogram) payloads, which account for 86 percent of the products sold on Amazon. They need to ask permission because the FAA specifically banned such behavior last month.

Insurance Claims Reveal Hidden Electronic Damage From Geomagnetic Storms

Soulskill posted 5 hours ago | from the new-bofh-excuse dept.

Technology 55

KentuckyFC writes: On 13 March 1989, a powerful geomagnetic storm severely disrupted the Hydro-Québec high-voltage grid triggering numerous circuit breakers and blacking out much of eastern Canada and the northeastern U.S. Since then, Earth has been hit by numerous solar maelstroms without such large-scale disruption. But the smaller-scale effect of these storms on low voltage transmissions lines, and the equipment connected to them, has been unknown. Until now. Researchers from the Lockheed Martin Solar and Astrophysics Laboratory have analyzed insurance claims for damage to industrial electrical equipment between 2000 and 2010 and found a clear correlation with geomagnetic activity. They say that the number of claims increases by up to 20 per cent on the days of highest geomagnetic activity. On this basis, they calculate that the economic impact of geomagnetic damage must amount to several billion dollars per year. That raises the question of the impact these storms have on household electronic equipment, such as computers, smartphones and tablets, and whether domestic insurance claims might throw some light on the issue.

Child Thought To Be Cured of HIV Relapses, Tests Positive Again

Medicine 109

An anonymous reader writes: The Mississippi child, who was born with HIV passed from her mother, received HIV treatment for 18 months after her birth. In the course of over two years after the treatment, her blood indicated no trace of the virus or of HIV-specific antibodies, leading many to hope that she may have been cured completely. Earlier this month, however, the virus was detected again. Nearly 4 years old, the child is once more being given HIV treatment, and scientists are trying to figure out how she could have gone so long before relapsing.

Google's Experimental Newsroom Avoids Negative Headlines

The Media 96

theodp writes: After Brazil's dramatic World Cup defeat by Germany, writes NPR's Aarti Shahani, Google's experimental newsroom focused on search trends that didn't rub salt in Brazil's wounds, choosing to not publish a single trend on Brazilian search terms. Copywriter Tessa Hewson said they were just too negative. "We might try and wait until we can do a slightly more upbeat trend." It's a decision that puzzles Shahani, but producer Sam Clohesy explained, "a negative story about Brazil won't necessarily get a lot of traction in social." In old-school newsrooms, if it bleeds, it leads. But because this new newsroom is focused on getting content onto everyone's smartphone, marketing expert Rakesh Agrawal says, editors may have another bias: to comb through the big data in search of happy thoughts.

Asteroid Mining Bill Introduced In Congress To Protect Private Property Rights

Soulskill posted 7 hours ago | from the you-can't-take-the-sky-from-me dept.

Space 146

MarkWhittington writes: "Rep. Bill Posey (R-FL) announced on Thursday that he was introducing a bill along with Rep, Derek Kilmer (D-WA) called the American Space Technology for Exploring Resource Opportunities in Deep Space (ASTEROIDS) Act of 2014 (PDF). The act is designed to protect the private property rights for entities mining asteroids and to otherwise encourage asteroid mining. The bill is in apparent reaction to efforts by companies like Planetary Resources and Deep Space Industries to locate and mine Earth approaching asteroids for their resources.

The crucial part of the short piece of legislation states that the resources mined from an asteroid would be the property of the entity undertaking the operation. This language gets around the provision of the Outer Space Treaty that says states are forbidden to establish national sovereignty over celestial bodies, which would be a prerequisite to the United States allowing a private entity to own an asteroid. It rather grants mineral rights to the asteroid, something the treaty does not mention. There is no enforcement mechanism in the event of a dispute with another country, however."

Aereo Embraces Ruling, Tries To Re-Classify Itself As Cable Company

Television 116

An anonymous reader writes Rather than completely shuttering its TV-over-the-internet business, Aereo has decided to embrace the Supreme Court's recent decision against it. In a letter to the lower court overseeing the litigation between the company and network broadcasters, Aereo asks to be considered a cable company and to be allowed to pay royalties as such. Cable companies pay royalties to obtain a copyright statutory license under the Copyright Act to retransmit over-the-air programming, and the royalties are set by the government, not the broadcasters. The broadcasters are not happy with this move, of course, claiming that Aereo should not be allowed to flip-flop on how it defines itself.

Hair-Raising Technique Detects Drugs, Explosives On Human Body

Science 135

sciencehabit writes Scientists have found a way to combine Van de Graaff generators with a common laboratory instrument to detect drugs, explosives, and other illicit materials on the human body. In the laboratory, scientists had a volunteer touch a Van de Graaff generator for 2 seconds to charge his body to 400,000 volts. This ionized compounds on the surface of his body. The person then pointed their charged finger toward the inlet of a mass spectrometer, and ions from their body entered the machine. In various tests, the machine correctly identified explosives, flammable solvents, cocaine, and acetaminophen on the skin.

Google, Dropbox, and Others Forge Patent "Arms Control Pact"

jfruh writes Patent trolling is a serious irritant and financial drain on many big tech companies — but those same companies can't guarantee that their own future management won't sell the patents they own to a 'non-practicing entity', especially in the case of sale or bankruptcy. That's why a number of tech giants, including Google and Dropbox, have formed the 'License or Transfer Network,' in which a patent will automatically be licensed to everyone else in the network in the event that it's sold to a third party.

blackbeak (1227080) writes The Washington Post reports that the Journal of Vibration and Control's review system was hijacked by a ring of reviewers. 60 articles have been retracted as a result. "After a 14-month investigation, JVC determined the ring involved “aliases” and fake e-mail addresses of reviewers — up to 130 of them — in an apparently successful effort to get friendly reviews of submissions and as many articles published as possible by Chen and his friends.'On at least one occasion, the author Peter Chen reviewed his own paper under one of the aliases he created,' according to the SAGE announcement."

FTC Files Suit Against Amazon For In-App Purchases

Charliemopps writes The Federal Trade Commission has filed suit against Amazon for illegally billing parents for in-app purchases of digital goods prior to requiring a password for making purchases. "The FTC's complaint, filed Thursday, asks the court to force Amazon to refund the money to those customers. In-app purchases typically involve virtual goods bought within an app, like extra coins or energy in a game, according to the FTC. Some bills totaled hundreds of dollars, and some virtual goods cost as much as $99.99." We recently told you about Amazon's refusal to reach a settlement over these FTC complaints.

SpaceX Wins FAA Permission To Build a Spaceport In Texas

Jason Koebler writes SpaceX just got approval from the Federal Aviation Administration to build a 56.5-acre spaceport along the Gulf of Mexico on the Texas-Mexico border—a huge step toward actually making the spaceport a reality. Wednesday, the FAA, which handles all commercial space launch permitting in the United States, issued what's known as a "Record of Decision" that suggests the agency would allow the company to launch 10 Falcon 9 rockets and two Falcon Heavy rockets per year out of the spaceport, through at least 2025.

Hints of Life's Start Found In a Giant Virus

samzenpus posted yesterday | from the that's-a-big-one dept.

Science 126

An anonymous reader points out this update on the world's largest virus, discovered in March. Chantal Abergel and Jean-Michel Claverie were used to finding strange viruses. The married virologists at Aix-Marseille University had made a career of it. But pithovirus, which they discovered in 2013 in a sample of Siberian dirt that had been frozen for more than 30,000 years, was more bizarre than the pair had ever imagined a virus could be. In the world of microbes, viruses are small — notoriously small. Pithovirus is not. The largest virus ever discovered, pithovirus is more massive than even some bacteria. Most viruses copy themselves by hijacking their host's molecular machinery. But pithovirus is much more independent, possessing some replication machinery of its own. Pithovirus's relatively large number of genes also differentiated it from other viruses, which are often genetically simple — the smallest have a mere four genes. Pithovirus has around 500 genes, and some are used for complex tasks such as making proteins and repairing and replicating DNA. "It was so different from what we were taught about viruses," Abergel said. The stunning find, first revealed in March, isn't just expanding scientists' notions of what a virus can be. It is reframing the debate over the origins of life."

McGruber writes In a letter to the U.S. Federal Communication Commission and the Department of Justice, Senator Al Franken warned that letting AT&T acquire Direct TV could turn AT&T into a gatekeeper to the mobile Internet. Franken also complained that AT&T took inappropriate steps to block Internet applications like Google Voice and Skype: "AT&T has a history of skirting the spirit, and perhaps the letter' of the government's rules on net neutrality, Franken wrote."

The Oatmeal Convinces Elon Musk To Donate $1 Million To Tesla Museum

Ars Technica notes (as does Oatmeal creator Matthew Inman) that Elon Musk has agreed to donate $1 million towards the restoration of Nikola Tesla's old lab as a museum, a project that Inman has been pushing for some time now. And if you happen to get there in a Tesla, you're in luck: Musk is also planning to install one of his company's superchargers in the parking lot. (At the other end of the east coast, you can visit a very different kind of Tesla museum.)
