An anonymous reader quotes a report from The New York Times: Will it soon be possible to simulate the feeling of a spirit not attached to any particular physical form using virtual or augmented reality? If so, a good place to start would be to figure out the minimal amount of body we need to feel a sense of self, especially in digital environments where more and more people may find themselves for work or play. It might be as little as a pair of hands and feet, report Dr. Michiteru Kitazaki and a Ph.D. student, Ryota Kondo. In a paper published Tuesday in Scientific Reports, they showed that animating virtual hands and feet alone is enough to make people feel their sense of body drift toward an invisible avatar (Warning: source may be paywalled; alternative source). Their work fits into a corpus of research on illusory body ownership, which has challenged understandings of perception and contributed to therapies like treating pain for amputees who experience phantom limb.

Using an Oculus Rift virtual reality headset and a motion sensor, Dr. Kitazaki's team performed a series of experiments in which volunteers watched disembodied hands and feet move two meters in front of them in a virtual room. In one experiment, when the hands and feet mirrored the participants' own movements, people reported feeling as if the space between the appendages were their own bodies. In another experiment, the scientists induced illusory ownership of an invisible body, then blacked out the headset display, effectively blindfolding the subjects. The researchers then pulled them a random distance back and asked them to return to their original position, still virtually blindfolded. Consistently, the participants overshot their starting point, suggesting that their sense of body had drifted or "projected" forward, toward the transparent avatar.

Christopher Ingraham, writing for The Washington Post: China, Russia and other authoritarian countries inflate their official GDP figures by anywhere from 15 to 30 percent in a given year, according to a new analysis of a quarter-century of satellite data. The working paper, by Luis R. Martinez of the University of Chicago, also found that authoritarian regimes are especially likely to artificially boost their gross domestic product numbers in the years before elections, and that the differences in GDP reporting between authoritarian and non-authoritarian countries can't be explained by structural factors, such as urbanization, composition of the economy or access to electricity. Martinez's findings are derived from a novel data source: satellite imagery that tracks changes in the level of nighttime lighting within and between countries over time.

As Japan's population ages, so do its drivers. Japan has the oldest population in the world, with nearly 28 percent of its residents above 65 years old. One in seven people are over 75. In the United States, by comparison, that figure is closer to one in 16. From a report: According to data compiled by Japan's national police agency, drivers between 16 and 24 are more likely to cause traffic accidents than any other age group. But last year, drivers over 75 caused twice as many fatal accidents per 100,000 drivers as those under that age. Among drivers over 80 years old, the rate was three times as high as for drivers under that age. The news media regularly features grisly reports of deaths caused by older drivers, some of whom are later discovered to have Alzheimer's disease.

Since 2009, all drivers 75 and older must submit to a test of their cognitive functioning when they renew their licenses [Editor's note: the link may be paywalled], typically once every three years. Under a new traffic law that took effect in March 2017, those who score poorly are sent to a doctor for examination, and if they are found to have dementia, the police can revoke their licenses. More than 33,000 drivers who took the cognitive test last year showed what the police deemed to be signs of cognitive impairment and were ordered to see a doctor. The police revoked just over 1,350 licenses after doctors diagnosed dementia.

chicksdaddy shares a report from The Security Ledger: Kremlin linked news sites like RT and Sputnik figure prominently in an online disinformation campaign portraying Syrian humanitarian workers ("White Helmets") as terrorists and crisis actors, according to an analysis (PDF) by researchers at University of Washington and Harvard. An online "echosystem" of propaganda websites including Russia backed news outlets Sputnik and RT is attacking the credibility of humanitarian workers on the ground in rebel occupied Syria, according to a new analysis by researchers at The University of Washington and Harvard University. Online rumors circulated through so called "alternative" media sites have attacked the Syrian Civil Defense (aka "White Helmets") as "crisis actors" and Western agents working on behalf of the U.S. and NATO. Statistical analysis of the online rumors reveal a tight network of websites sharing nearly identical content via Twitter and other social media platforms, wrote Kate Starbird. Starbird is an Assistant Professor of Human Centered Design & Engineering at University of Washington and a leading expert on so-called "crisis informatics."

In activity reminiscent of the disinformation campaigns that roiled the U.S. Presidential election in 2016, articles by what Starbird describes as "a few prominent journalists and bloggers" writing for self described "alternative" news sites like 21stCenturyWire, GlobalResearch, MintPressNews, and ActivistPost are picked up by other, smaller and more niche websites including both left- and right-leaning partisan news sites, "clickbait sites," and conspiracy theory websites. Government funded media outlets from Syria, Iran, Hezbollah and Russia figure prominently in the Syrian disinformation campaign, Starbird's team found. In particular, "Russian government-funded media outlets (i.e. SputnikNews and RT) play a prominent and multi-faceted role within this ecosystem," she wrote.

An anonymous reader quotes a report from Bloomberg: Since acquiring Skype from private equity investors, Microsoft has refocused the online calling service on the corporate market, a change that has made Skype less intuitive and harder to use, prompting many Skypers to defect to similar services operated by Apple, Google, Facebook and Snap. The company hasn't updated the number of Skype users since 2016, when it put the total at 300 million. Some analysts suspect the numbers are flat at best, and two former employees describe a general sense of panic that they're actually falling. The ex-Microsofters, who requested anonymity to discuss confidential statistics, say that as late as 2017 they never heard a figure higher than 300 million discussed internally.

Chief Executive Officer Satya Nadella has repeatedly said he wants the company's products to be widely used and loved. By turning Skype into a key part of its lucrative Office suite for corporate customers, Microsoft is threatening what made it appealing to regular folks in the first place. [...] Focusing on corporations was a reasonable strategy and one shared by Skype's prior management. Originally [former Microsoft CEO Steve Ballmer] and company pledged to let Skype operate independently from Lync, Microsoft's nascent internet phone service for corporations. But two years later the company began merging the two into Skype for Business and folded that into Office. Today, Microsoft is using Skype for Business to help sell subscriptions to its cloud-based Office 365 and steal customers from Cisco. Microsoft has essentially turned Skype into a replacement for a corporate telephone system -- with a few modern features borrowed from instant messaging, artificial intelligence and social networking. In closing, Bloomberg argues "the complexity of the corporate software (security, search, and the ability to host town halls) crowds out the simplicity consumers prefer (ease-of-use and decent call quality)."

Young professionals in China are pushing back against employers who expect them to work around the clock, saying no to the decades old "rule of 996" -- working from 9am to 9pm six days a week. From a report: At the forefront are millennials who are often better educated, more aware of their rights and more interested in finding something fulfilling than the previous generation. And as only children (China's one-child policy wasn't eased until 2015), they are also outspoken and pampered. "In my experience young people, especially the post-90s generation, are reluctant to work overtime -- they are more self-centered," says labour rights expert Li Jupeng, one of many who have observed some millennials challenging the 996 concept.

The relative affluence of their parents and grandparents is part of the reason. China's rapid economic transformation has given rise to a sizeable middle class, with almost 70% of the country's urban population making between $9,000 and $34,000 annually in 2012. In 2000, that figure was just 4%. As only children, millennials are receiving a lot of support from their families -- including a financial safety net should their careers not go as planned. Although their options for pushing back are limited, some are no longer willing to put in long hours for a meagre paycheck.

An anonymous reader quotes a report from TechCrunch: ZTE wasn't kidding around when it suggested that a U.S. Department of Commerce order would "severely impact" its survival. It's hard to image a successful path around the seven-year ban on the sale of U.S. products to the company imposed after it reportedly failed to sufficiently reprimand staff for flouting Iranian sanctions. Earlier today, in fact, the Chinese smartphone/telecom manufacturer announced that it had ceased its main business operations as it attempts to figure out the best way forward. "As a result of the Denial Order, the major operating activities of the company have ceased," the company wrote in an exchange filing spotted by Reuters. "As of now, the company maintains sufficient cash and strictly adheres to its commercial obligations subject in compliance with laws and regulations."

Glassdoor, the popular job-hunting platform that gives people a window into conditions at hundreds of thousands of companies, has agreed to be acquired by Japan's Recruit Holdings for $1.2 billion cash. From a report: Recruit Holdings, a large Japanese human resources company that owns other job sites like Indeed, spent eight figures in cash to acquire the decade-old company. Glassdoor hadn't raised new money in about two years, when it was valued by investors at around $860 million, so it likely needed to decide whether to raise more money, sell or try to go public. The company reportedly was at least considering an IPO in the second half of 2018 and was interviewing banks that could take them there.

Google Maps is getting a new augmented reality Street View mode to help you follow directions in real time, along with personalized recommendations to help you discover places in your neighborhood. The Verge reports: The new AR features combine Google's existing Street View and Maps data with a live feed from your phone's camera to overlay walking directions on top of the real world and help you figure out which way you need to go. In addition to directions, the new AR mode can help identify nearby places, too, and Google is even testing adding a helpful augmented reality animal guide to lead you along the way.

Maps is also getting a new tab called "For You" that will feature recommendations specifically tailored to you. Google is using a new "match number" system, which will generate a personal score on how much it thinks you'll like the recommendation based on your past likes and reviews, as well as your saved food preferences. Google is also adding more social features to Maps, making it possible to share multiple places to friends with a single action, and vote on them together in real time to decide where to go without having to leave the app. The AR directions feature has no release date, but the new social and recommendations features will be coming to both Android and iOS later this summer.

A modern car should be treated like a personal computer. Before you sell it, you should make sure all connections are severed and personal information is wiped before handing the keys to the buyer. The Drive reports of a former Volkswagen owner who recently discovered that her connection to her car lingered even after her old car was sold to a new owner. In what may seem like a public service announcement, The Drive writes: "It's up to you to wipe out your data and connections, not the dealer or manufacturer." From the report: Ashley Sehatti sold her 2015 Jetta back to her local VW dealer back in December. Like most car owners, she figured that was the end of it. So she was baffled when she continued to get monthly reports about her car's health. After receiving April's report, she attempted to log into her account for Car-Net, Volkswagen's connected car service. Much to Sehatti's surprise, she found that not only was her account still active, she still had access to her old car. She could see its current mileage, the status of its locks and lights, and, most disturbingly, its current location on a map. Sehatti was not aware that she, not Volkswagen or her dealer, was responsible for disabling access to Car-Net when she sold the car. Its new owner likely didn't sign up for the Car-Net service, which meant that Sehatti's access remained available, even though she didn't even want it. "Our Car-Net Terms of Service explicitly outlines that as a subscriber, the customer has the responsibility to terminate the contract when selling their vehicle," writes Catharina Mette, the head of technology communications for Volkswagen Group's North Americas region. "This is a practice common in the industry." The takeaway here is to read the Terms of Service because most car owners don't do so in any great detail.

An anonymous reader quotes a report from Ars Technica: Alan Turing is rightly famed for his contributions to computer science. But one of his key concepts -- an autonomous system that can generate complex behavior from a few simple rules -- also has applications in unexpected places, like animal behavior. One area where Turing himself applied the concept is in chemistry, and he published a paper describing how a single chemical reaction could create complex patterns like stripes if certain conditions are met. It took us decades to figure out how to actually implement Turing's ideas about chemistry, but we've managed to create a number of reactions that display the behaviors he described. And now, a team of Chinese researchers has figured out how to use them to make something practical: a highly efficient desalination membrane.

To make this a true Turing-style system, the researchers dissolved a large molecule in water. This had the effect of making the water more viscous, which slowed the diffusion of the activator. In addition, the molecule was chosen so that the activator would stick to it, slowing things down even further. The end result was a system similar to the ones defined over a half-century ago. Imaging of the features show that rather than simply thickening the membrane, the membrane retained the same width in these areas; instead, it bulged out to form the structures. That's critical, as the amount of surface area exposed to a salt solution should influence how much water gets through the membrane. In fact, the researchers confirmed that more water was purified when the new membranes were used (the version with the stripes outperformed the dotted one). Unfortunately, the researchers don't compare this system to commercially available membranes. The report has been published in the journal Science.

Late last year, Vine's co-founder, Dom Hofmann, said he was working on "a follow-up to Vine," after the six-second video social media app was shut down by Twitter in October. "I'm going to work on a follow-up to vine. i've been feeling it myself for some time and have seen a lot of tweets, dms, etc.," Hofmann tweeted at the time. Well, several months have passed and we have learned that Vine v2 will be postponed for an "indefinite amount of time" while Hofmann figures out funding and logistical hurdles. The Verge reports: The announcement, made on the v2 forums and reposted this morning by the official v2 Twitter handle, is a disappointing but understanding turn of events. Back in January, Hofmann suggested the app may launch as soon as this summer, which was an ambitious timetable. Now, Hofmann says that, despite the immense interest in his project, he has to take the time to make sure it doesn't fall apart before continuing. He cites a need for substantial venture funding to get v2 off the ground after initially thinking he may be able to self-fund it. "Long story short, in order to work, the v2 project needs to operate as a company with sizable external funding, probably from investors," Hofmann writes. "This is difficult because I already run an early-stage company (Innerspace VR, a creative immersive entertainment studio he founded after selling Vine to Twitter years ago) that is in the middle of development. Very few backers would be happy with the split attention, and I wouldn't be either. This is potentially solvable, but it's going to take time for the space and resources to become available."

On stage today at Radio City Music Hall, YouTube CEO Susan Wojcicki made a surprising revelation: the service gets 1.8 billion logged-in viewers every month. And that doesn't include people who aren't logged in -- which means the actual number of people watching YouTube is definitely much higher. From a report: Last June, the service had 1.5 billion logged-in watchers. On TVs alone, people are now watching 150 million hours of YouTube every day. The latest figures are yet another sign that YouTube's reach is staggering, something that Wojcicki wanted to make crystal clear for the audience of advertisers and potential partners at its annual BrandCast event.

An anonymous reader quotes a report from Gizmodo: Back in 2012, a Reddit user posted a map claiming to show the longest straight line that could be traversed across the ocean without hitting land. Intrigued, a pair of computer scientists have developed an algorithm that corroborates the route, while also demonstrating the longest straight line that can be taken on land. The researchers, Rohan Chabukswar from United Technologies Research Center Ireland, and Kushal Mukherjee from IBM Research India, created the algorithm in response to a map posted by reddit user user kepleronlyknows, who goes by Patrick Anderson in real life. His map showed a long, 20,000 mile route extending from Pakistan through the southern tips of Africa and South America and finally ending in an epic trans-Pacific journey to Siberia. On a traditional 2D map, the path looks nothing like a straight line; but remember, the Earth is a sphere.

Anderson didn't provide any evidence for the map, or an explanation for how the route was calculated. In light of this, Chabukswar and Mukherjee embarked upon a project to figure out if the straight line route was indeed the longest, and to see if it was possible for a computer algorithm to solve the problem, both for straight line passages on water without hitting land or an ice sheet, and for a continuous straight line passage on land without hitting a major body of water. Their ensuing analysis was posted to the pre-print arXiv server earlier this month, and has yet to go through peer review. "There would be 233,280,000 great circles to consider to find the global optimum, and each great circle would have 21,600 individual points to process -- a staggering 5,038,848,000,000 points to verify," the researchers wrote in their study.

Even as most big banks have maintained distance from virtual currency Bitcoin, Goldman Sachs is bucking the risks: It plans to set up what appears to be the first Bitcoin trading operation at a Wall Street bank. From a report: In a step that is likely to lend legitimacy to virtual currencies -- and create new concerns for Goldman -- the bank is about to begin using its own money to trade with clients in a variety of contracts linked to the price of Bitcoin. While Goldman will not initially be buying and selling actual Bitcoins, a team at the bank is looking at going in that direction if it can get regulatory approval and figure out how to deal with the additional risks associated with holding the virtual currency. Rana Yared, one of the Goldman executives overseeing the creation of the trading operation, said the bank was cleareyed about what it was getting itself into. "I would not describe myself as a true believer who wakes up thinking Bitcoin will take over the world," Ms. Yared said. "For almost every person involved, there has been personal skepticism brought to the table."

In its first year, the Trump administration kept one little-known courtroom in the capital busy. From a report: A secretive Washington DC-based court that oversees the US government's foreign spy programs denied more surveillance orders during President Donald Trump's first year than in the court's 40-year history, according to newly released figures. Annual data published Wednesday by the US Courts shows that the Foreign Intelligence Surveillance (FISA) Court last year denied 26 applications in full, and 50 applications in part. That's compared to 21 orders between when the court was first formed in 1978 and President Barack Obama's final year in office in 2016.

Atlanta is setting aside more than $2.6 million on recovery efforts stemming from a ransomware attack, which crippled a sizable part of the city's online services. ZDNet reports: The city was hit by the notorious SamSam ransomware, which exploits a deserialization vulnerability in Java-based servers. The ransom was set at around $55,000 worth of bitcoin, a digital cryptocurrency that in recent weeks has wildy fluctated in price. But the ransom was never paid, said Atlanta city spokesperson Michael Smith in an email. Between the ransomware attack and the deadline to pay, the payment portal was pulled offline by the ransomware attacker. According to newly published emergency procurement figures, the city is projected to spend as much as 50 times that amount in response to the cyberattack. Between March 22 and April 2, the city budgeted $2,667,328 in incident response, recovery, and crisis management.

Adam Frank, writing for The Atlantic: We're used to imagining extinct civilizations in terms of the sunken statues and subterranean ruins. These kinds of artifacts of previous societies are fine if you're only interested in timescales of a few thousands of years. But once you roll the clock back to tens of millions or hundreds of millions of years, things get more complicated.

When it comes to direct evidence of an industrial civilization -- things like cities, factories, and roads -- the geologic record doesn't go back past what's called the Quaternary period 2.6 million years ago. For example, the oldest large-scale stretch of ancient surface lies in the Negev Desert. It's "just" 1.8 million years old -- older surfaces are mostly visible in cross section via something like a cliff face or rock cuts. Go back much farther than the Quaternary and everything has been turned over and crushed to dust.

And, if we're going back this far, we're not talking about human civilizations anymore. Homo sapiens didn't make their appearance on the planet until just 300,000 years or so ago. [...] Given that all direct evidence would be long gone after many millions of years, what kinds of evidence might then still exist? The best way to answer this question is to figure out what evidence we'd leave behind if human civilization collapsed at its current stage of development. Mr. Frank, along with Gavin Schmidt, Director of the NASA Goddard Institute for Space Studies, have published their research on the subject [PDF].

Many of Amazon's warehouse workers have to buy their groceries with food stamps through America's Supplemental Nutrition Assistance Program, reports the Intercept. In Arizona, new data suggests that one in three of the company's own employees depend on SNAP to put food on the table. In Pennsylvania and Ohio, the figure appears to be around one in 10. Overall, of five states that responded to a public records request for a list of their top employers of SNAP recipients, Amazon cracked the top 20 in four.

Though the company now employs 200,000 people in the United States, many of its workers are not making enough money to put food on the table... "The average warehouse worker at Walmart makes just under $40,000 annually, while at Amazon would take home about $24,300 a year," CNN reported in 2013. "That's less than $1,000 above the official federal poverty line for a family of four."
In addition Amazon uses temp workers who may also be on food stamps, notes the article, adding that in 2017 Amazon received $1.2 billion in state and local subsidies, while effectively paying no federal income tax.

"The American people are financing Amazon's pursuit of an e-commerce monopoly every step of the way: first, with tax breaks, subsidies, and infrastructure improvements meant to lure fulfillment centers into town, and later with federal transfers to pay for warehouse workers' food."

An anonymous reader quotes former Reddit product head Dan McComas: I think, ultimately, the problem that Reddit has is the same as Twitter and Discord. By focusing on growth and growth only and ignoring the problems, they amassed a large set of cultural norms on their platforms. Their cultural norms are different for every community, but they tend to stem from harassment or abuse or bad behavior, and they have worked themselves into a position where they're completely defensive... I really don't believe it's possible for either of them to catch up on the problem. I think the best that they can do is figure out how to hide this behavior from an average user.

I don't see any way that it's going to improve. I have no hope for either of those platforms. I just think that the problems are too ingrained, in not only the site and the site's communities and users but in the general understanding and expectations of the public... I don't think that they're going to be able to turn these things around...

I fundamentally believe that my time at Reddit made the world a worse place. And that sucks, and it sucks to have to say that about myself... I've got a lot of advice for start-ups, and it's not very fucking complicated. It's just: Think about the impact that you want to have on your users and on the people consuming your content and do the right thing... Don't be idiots about it. You're people, you see what's going on, you see trends that are forming, just fucking do something. It's not that hard.
