In a multi-'cat' experiment, the textbook interpretation of quantum theory seems to lead to contradictory pictures of reality, physicists claim. New submitter Lanodonal shares a report: In the world's most famous thought experiment, physicist Erwin Schrodinger described how a cat in a box could be in an uncertain predicament. The peculiar rules of quantum theory meant that it could be both dead and alive, until the box was opened and the cat's state measured. Now, two physicists have devised a modern version of the paradox by replacing the cat with a physicist doing experiments -- with shocking implications.

Quantum theory has a long history of thought experiments, and in most cases these are used to point to weaknesses in various interpretations of quantum mechanics. But the latest version, which involves multiple players, is unusual: it shows that if the standard interpretation of quantum mechanics is correct, then different experimenters can reach opposite conclusions about what the physicist in the box has measured. This means that quantum theory contradicts itself.

The conceptual experiment has been debated with gusto in physics circles for more than two years -- and has left most researchers stumped, even in a field accustomed to weird concepts. "I think this is a whole new level of weirdness," says Matthew Leifer, a theoretical physicist at Chapman University in Orange, California. The authors, Daniela Frauchiger and Renato Renner of the Swiss Federal Institute of Technology (ETH) in Zurich, posted their first version of the argument online in April 2016. The final paper [PDF] appears in Nature Communications on 18 September.

Cloudflare wants routing issues to be a thing of the past by deploying a new feature to try to stop route leaks and hijacks in their tracks. From a report: Cloudflare told TechCrunch that rolling out resource public key infrastructure (RPKI) to all of its customers for free will make it far more difficult to reroute traffic -- either by accident or deliberately. RPKI, in a nutshell, helps to ensure that traffic goes to the right place through a route that's verified as legitimate and correct by using cryptographically signed certificates.

"When two networks connect with each other -- say, AT&T and Verizon -- they announce the set of IP addresses for which they should be sent traffic," said Nick Sullivan, Cloudflare's head of cryptography. "The RPKI is a security framework to make sure a network announces only its legitimate IP addresses." Cloudflare's push in the right direction follows an effort by the National Institute for Standards and Technology, which last week published its first draft of a new standard, which incorporates RPKI as one of three components that will help prevent route leaks and hijacks. A possible approval is expected in the coming weeks.

Box-office giant Ticketmaster is recruiting professional scalpers who cheat its own system to expand its resale business and squeeze more money out of fans, a CBC News/Toronto Star investigation reveals. The report adds: In July, the news outlets sent a pair of reporters undercover to Ticket Summit 2018, a ticketing and live entertainment convention at Caesars Palace in Las Vegas. Posing as scalpers and equipped with hidden cameras, the journalists were pitched on Ticketmaster's professional reseller program. Company representatives told them Ticketmaster's resale division turns a blind eye to scalpers who use ticket-buying bots and fake identities to snatch up tickets and then resell them on the site for inflated prices. Those pricey resale tickets include extra fees for Ticketmaster. "I have brokers that have literally a couple of hundred accounts," one sales representative said. "It's not something that we look at or report." CBC shared its findings with Alan Cross, a veteran music journalist and host of the radio program The Ongoing History of New Music, who suspects the ticket-buying public will be far from impressed: "This is going to be a public relations nightmare." He said there have been "whispers of this in the ticket-selling community, but it's never been outlined quite like this before."

European Competition Commissioner Margrethe Vestager has begun questioning merchants on Amazon's use of their data, Vestager said Wednesday. The issue, she said, is whether Amazon is using data from the merchants it hosts on its site to secure an advantage in selling products against those same retailers. From a report: "These are very early days and we haven't formally opened a case. We are trying to make sure that we get the full picture," Vestager said during a news conference Wednesday. The probe comes as the world's largest online retailer faces growing calls for regulation. Investors and insiders have long cited Amazon's size and reach as reason to break the company up. President Donald Trump has hinted at antitrust action against Amazon as part of continued attacks against CEO Jeff Bezos, who also owns The Washington Post. U.S. Attorney General Jeff Sessions was set to meet this month with state officials to discuss antitrust concerns in Silicon Valley, though much of the regulation on Big Tech thus far has come out of Brussels.

China might be at loggerheads with the United States over trade, but it is calling for a friendlier approach to the development of artificial intelligence. From a report: Speaking at the World Artificial Intelligence Conference in Shanghai this week, China's vice premier, Liu He, said that AI would depend heavily on international cooperation. "We're hoping that all countries, as members of the global village, will be inclusive and support each other so that we can respond to the double-edged-sword effect of new technologies," He said through a translator. "AI represents a new era. Cross-national and cross-discipline cooperation is inevitable."

President Xi Jinping delivered a similar message in a letter presented at the same conference. Xi said that China would "share results with other countries in the field of artificial intelligence." He also called for collaboration between nations on AI topics such as ethics, law, governance, and security. This new, softer approach to artificial intelligence comes just over a year after the Chinese government announced an ambitious and aggressive AI plan. This blueprint called for Chinese AI researchers to lead the world by 2030, and for domestic companies to build an industry worth more than $150 billion. China's tech industry has already embraced machine learning and AI at an impressive rate.

An anonymous reader shares a report: All around us, algorithms provide a kind of convenient source of authority: an easy way to delegate responsibility, a short cut we take without thinking. Who is really going to click through to the second page of Google results every time and think critically about the information that has been served up? Or go to every airline to check if a comparison site is listing the cheapest deals? Or get out a ruler and a road map to confirm that their GPS is offering the shortest route? But already in our hospitals, our schools, our shops, our courtrooms and our police stations, artificial intelligence is silently working behind the scenes, feeding on our data and making decisions on our behalf. Sure, this technology has the capacity for enormous social good -- it can help us diagnose breast cancer, catch serial killers, avoid plane crashes and, as the health secretary, Matt Hancock, has proposed, potentially save lives using NHS data and genomics. Unless we know when to trust our own instincts over the output of a piece of software, however, it also brings the potential for disruption, injustice and unfairness.

If we permit flawed machines to make life-changing decisions on our behalf -- by allowing them to pinpoint a murder suspect, to diagnose a condition or take over the wheel of a car -- we have to think carefully about what happens when things go wrong.

Newegg is clearing up its website after a month-long data breach. TechCrunch: Hackers injected 15 lines of card skimming code on the online retailer's payments page which remained for more than a month between August 14 and September 18, Yonathan Klijnsma, a threat researcher at RiskIQ, told TechCrunch. The code siphoned off credit card data from unsuspecting customers to a server controlled by the hackers with a similar domain name -- likely to avoid detection. The server even used an HTTPS certificate to blend in. The code also worked for both desktop and mobile customers -- though it's unclear if mobile customers are affected.

The online electronics retailer removed the code on Tuesday after it was contacted by incident response firm Volexity, which first discovered the card skimming malware and reported its findings. Newegg is one of the largest retailers in the US, making $2.65 billion in revenue in 2016. The company touts more than 45 million monthly unique visitors, but it's not known precisely how many customers completed transactions during the period.

LLVM release manager Hans Wennborg announced Wednesday the official availability of LLVM 7.0 compiler stack as well as associated sub-projects including the Clang 7.0 C/C++ compiler front-end, Compiler-RT, libc++, libunwind, LLDB, and others. From a report: There is a lot of LLVM improvements ranging from CPU improvements for many different architectures, Vega 20 support among many other AMDGPU back-end improvements, the new machine code analyzer utility, and more. The notable Clang C/C++ compiler has picked up support for function multi-versioning (FMV), initial OpenCL C++ support, and many other additions. See my LLVM 7.0 / Clang 7.0 feature overview for more details on the changes with this six-month open-source compiler stack update. Wennborg's release statement can be read on the llvm-announce list.

Sony announced Wednesday that it will release the PlayStation Classic micro console on December 3. It will cost $100 and come with 20 built-in games. From a report: Like Nintendo's NES Classic and SNES Classic, the PlayStation Classic will come packed with a list of beloved hits from the system's original library. There will be 20 games in all, but Sony only announced five of them today: Final Fantasy 7, Jumping Flash, R4: Ridge Racer Type 4, Tekken 3 and Wild Arms. "All of the pre-loaded games will be playable in their original format," the company said in an announcement post on the PlayStation Blog. Sony plans to launch the PlayStation Classic worldwide on Dec. 3 -- the 24th anniversary of the PlayStation's release. (The PS1 debuted in Japan on Dec. 3, 1994, and Sony didn't bring it to the West until September 1995.) The retro console will retail for $99.99 in the U.S., 89.99 pound in the U.K., 99.99 euro in Europe and 9,980 yen in Japan. For that price, customers will get the system and two controllers. The gamepads are full-size replicas of the PS1's original controller, not the DualShock, so they and don't include analog sticks or vibration. As you can see in the gallery above, the gamepads are wired USB devices that plug into the console in the same spot as the original system's controller ports.

An anonymous reader shares an excerpt from a report via The Guardian: People don't shout in Pontevedra -- or they shout less. With all but the most essential traffic banished, there are no revving engines or honking horns, no metallic snarl of motorbikes or the roar of people trying make themselves heard above the din -- none of the usual soundtrack of a Spanish city. What you hear in the street instead are the tweeting of birds in the camellias, the tinkle of coffee spoons and the sound of human voices. Teachers herd crocodiles of small children across town without the constant fear that one of them will stray into traffic.

"Listen," says the mayor, opening the windows of his office. From the street below rises the sound of human voices. "Before I became mayor 14,000 cars passed along this street every day. More cars passed through the city in a day than there are people living here." Miguel Anxo Fernandez Lores has been mayor of the Galician city since 1999. His philosophy is simple: owning a car doesn't give you the right to occupy the public space. "How can it be that the elderly or children aren't able to use the street because of cars?" asks Cesar Mosquera, the city's head of infrastructures. "How can it be that private property -- the car -- occupies the public space?" Lores became mayor after 12 years in opposition, and within a month had pedestrianized all 300,000 sq m of the medieval centre, paving the streets with granite flagstones. "The historical center was dead," Lores says. "There were a lot of drugs, it was full of cars -- it was a marginal zone. It was a city in decline, polluted, and there were a lot of traffic accidents. It was stagnant. Most people who had a chance to leave did so. At first we thought of improving traffic conditions but couldn't come up with a workable plan. Instead we decided to take back the public space for the residents and to do this we decided to get rid of cars."

Some of the benefits mentioned in the report include less traffic accidents and traffic-related deaths, and decreased CO2 emissions (70%). "Also, withholding planning permission for big shopping centers has meant that small businesses -- which elsewhere have been unable to withstand Spain's prolonged economic crisis -- have managed to stay afloat," reports The Guardian.

The European Commission has launched an antitrust investigation into the Volkswagen Group, BMW and Daimler, over allegations they colluded to keep certain emissions control devices from reaching the market in Europe, according to a statement the Commission released on Tuesday. CNET reports: The technologies the group allegedly sought to bury include a selective catalytic reduction system for diesel vehicles, which would help to reduce environmentally problematic oxides of nitrogen in passenger cars, and "Otto" particulate filters that trap particulate matter from gasoline combustion engines.

"The Commission is investigating whether BMW, Daimler and VW agreed not to compete against each other on the development and roll-out of important systems to reduce harmful emissions from petrol and diesel passenger cars," said Commissioner Margrethe Vestager, head of competition policy for the European Commission, in a statement. "These technologies aim at making passenger cars less damaging to the environment. If proven, this collusion may have denied consumers the opportunity to buy less polluting cars, despite the technology being available to the manufacturers."

After the House's unilateral support back in April, the Senate has unanimously voted to pass the Orrin G. Hatch Music Modernization Act, which is named in honor of the Republican senior senator from Utah -- a songwriter himself -- who will retire at the end of the year. Billboard explains the bill: The bill creates a blanket mechanical license and establishes a collective to administer it; reshapes how courts can determine rates, while making sure future performance rates hearings between performance rights organizations BMI and ASCAP and licensees rotate among all U.S. Southern District Court of New York Judges, instead of being assigned to the same two judges, Judge Denise Cote for ASCAP and Judge Louis Stanton for BMI, as its done now; creates a royalty for labels, artists and musicians to be paid by digital services for master recordings created prior to Feb. 15, 1972, while also eliminating a Digital Millennium Copyright Act of 1998 carve out for "pre-existing digital services" like Sirius XM and Music Choice that allows for certain additional considerations not given to any other digital service when rates are set; and codifies a process for Sound Exchange to pay producers and engineers royalties for records on which they have worked.

Over on the music publishing side of the business, there was much happiness too. For example, ASCAP noted that the legislation reforms an "outdated music licensing system and give music creators an opportunity to obtain compensation that more accurately reflects the value of music in a free market." Billboard notes that the revised Senate version "will go back to the House where it needs approval due to all the changes made to the bill in order to get it passed in the Senate." Once the House approves, it will then head to President Trump's desk.

An anonymous reader quotes a report from The Verge: For years, Facebook has publicly positioned its Messenger application as a way to connect with friends and as a way to help customers interact directly with businesses. But a new report from The Wall Street Journal today indicates that Facebook also saw its Messenger platform as a siphon for the sensitive financial data of its users, information it would not otherwise have access to unless a customer interacted with, say, a banking institution over chat. In this case, the WSJ report says not only did the banks find Facebook's methods obtrusive, but the companies also pushed back against the social network and, in some cases, moved conversations off Messenger to avoid handing Facebook any sensitive data. Among the financial firms Facebook is said to have argued with about customer data are American Express, Bank of America, and Wells Fargo.

The report says Facebook was interested in helping banks create bots for its Messenger platform, as part of a big push in 2016 to turn the chat app into an automated hub of digital life that could help you solve problems and avoid cumbersome customer service calls. But some of these bots, like the one American Express developed for Messenger last year, deliberately avoided sending transaction information over the platform after Facebook made clear it wanted to use customer spending habits as part of its ad targeting business. In some cases, companies like PayPal and Western Union negotiated special contracts that would let them offer many detailed and useful services like money transfers, the WSJ reports. But by and large, big banks in the U.S. have reportedly shied away from working with Facebook due to how aggressively it pushed for access to customer data. Facebook said in a statement to The Wall Street Journal: "Like many online companies, we partner with financial institutions to improve people's commerce experiences, like enabling better customer service, and people opt into these experiences. We've emphasized to partners that keeping people's information safe and secure is critical to these efforts. That has been and always will be our priority."

Adam Grant, an organizational psychologist, New York Times best-selling author, and The Wharton School's top professor, says Americans should work two hours less. Instead of the typical 9-to-5, people "should finish at 3pm," says Grant in a recent LinkedIn post. "We can be as productive and creative in 6 focused hours as in 8 unfocused hours." CNBC reports: In the LinkedIn post, Grant was weighing in on an Atlantic article about the time gap between when school and work days end, a bane for many parents. But it's not the first time Grant has given his stamp of approval to less work with more productivity. "Productivity is less about time management and more about attention management," Grant tweeted in July, highlighting an article about a successful four-day work week study. For the study, a New Zealand company adopted a four-day work week (at five-day pay) with positive results; the company saw benefits ranging from lower stress levels in employees to increased performance. In a recent blog post, billionaire Richard Branson also touted the success of a three-day or four-day work week. "It's easier to attract top talent when you are open and flexible," Branson said in the post. "It's not effective or productive to force them to behave in a conventional way."

"Many people out there would love three-day or even four-day weekends," said Branson. "Everyone would welcome more time to spend with their loved ones, more time to get fit and healthy, more time to explore the world."

Liam Tung reporting for ZDNet: Ubuntu maintainer Canonical and Microsoft have teamed up to release an optimized Ubuntu Desktop image that's available through Microsoft's Hyper-V gallery. The Ubuntu Desktop image should deliver a better experience when running it as a guest on a Windows 10 Pro host, according to Canonical. The optimized version is Ubuntu Desktop 18.04.1 LTS release, also known as Bionic Beaver. Microsoft's work with Canonical was prompted by its users who wanted a "first-class experience" on Linux virtual machines (VMs) as well as Windows VMs. To achieve this goal, Microsoft worked with the developers of XRDP, an open-source remote-desktop protocol (RDP) for Linux based on Microsoft's RDP for Windows. Thanks to that work, XRDP now supports Microsoft's Enhanced Session Mode, which allows Hyper-V to use the open-source implementation of RDP to connect to Linux VMs. This in turn gives Ubuntu VMs on Windows hosts a better mouse experience, an integrated clipboard, windows resizing, and shared folders for easier file transfers between host and guest. Microsoft's Hyper-V Quick Create VM setup wizard should also help improve the experience. "With the Hyper-V Quick Create feature added in the Windows 10 Fall Creators Update, we have partnered with Ubuntu and added a virtual machine image so in a few quick minutes, you'll be up and developing," said Clint Rutkas, a senior technical product manager on Microsoft's Windows Developer Team. "This is available now -- just type 'Hyper-V Quick Create' in your start menu."
