In a story earlier this week, Popular Science magazine explored an age-old topic: Do people need to safely eject a USB stick before they pull it from their computer? The magazine's take on it -- which is, as soon any ongoing transfer of files is complete, it is safe to yank out the flash drive -- has unsurprisingly stirred a debate. Here's what the magazine wrote: But do you really need to eject a thumb drive the right way? Probably not. Just wait for it to finish copying your data, give it a few seconds, then yank. To be on the cautious side, be more conservative with external hard drives, especially the old ones that actually spin. That's not the official procedure, nor the most conservative approach. And in a worst-case scenario, you risk corrupting a file or -- even more unlikely -- the entire storage device. To justify its rationale, the magazine has cited a number of computer science professors. In the same story, however, a director of product marketing at SanDisk made a case for why people should probably safely eject the device. He said, "Failure to safely eject the drive may potentially damage the data due to processes happening in the system background that are unseen to the user."

John Gruber of DaringFireball (where we originally spotted the story), makes a case for why users should safely eject the device before pulling it out: This is terrible advice. It's akin to saying you probably don't need to wear a seat belt because it's unlikely anything bad will happen. Imagine a few dozen people saying they drive without a seat belt every day and nothing's ever gone wrong, so it must be OK. (The breakdown in this analogy is that with seat belts, you know instantly when you need to be wearing one. With USB drives, you might not discover for months or years that you've got a corrupt file that was only partially written to disk when you yanked the drive.)

I see a bunch of "just pull out the drive and not worry about it" Mac users on Twitter celebrating this article, and I don't get it. On the Mac you have to do something on screen when you eject a drive. Either you properly eject it before unplugging the drive -- one click in the Finder sidebar -- or you need to dismiss the alert you'll get about having removed a drive that wasn't properly ejected. Why not take the course of action that guarantees data integrity? What are your thoughts on this? Do you think the answer varies across different file systems and operating systems?

Deep in Ecuador's lush Quijos Valley, a society thrived -- and then disappeared. But a lake preserved its story. From a report: In the 1850s, a team of botanists venturing into the cloud forest in the Quijos Valley of eastern Ecuador hacked their way through vegetation so thick they could barely make their way forward. This, they thought, was the heart of the pristine forest, a place where people had never gone. But they were very wrong. Indigenous Quijo groups had developed sophisticated agricultural settlements across the region, settlements that had been decimated with the arrival of Spanish explorers in the 1500s. In their absence, the forest sprung back. This process of societal collapse and forest reclamation is described in a new study published today in Nature Ecology and Evolution.

The Quijos Valley lies in one of the most biodiverse cloud forests in the world, along a pre-Columbian trade route that linked the rich Amazonian lowlands with the high Andes. Thousands of people lived there centuries before the Spanish arrived, farming maize, squash, beans, and even passionfruit in poor soil of the valley floor. The study's researchers found a tiny lake in the valley and dug down into the silt at the bottom, pulling up a plug of sediment that had built up over the last 1000 years -- and found evidence of human occupation going back to the very oldest part of the core. In the oldest layers, scientists found tiny pieces of pollen -- swept from the valley and the surrounding forest into the lake by wind -- from maize and other plants that only grow in open, airy conditions, which told them that humans were cultivating plants on the valley floor. They also found plenty of charcoal bits, indications that people had lit fires nearby.

Netflix shares plunged by more than 14% on Monday, after the firm reported disappointing subscriber growth. While the entertainment service added 5.2 million subscribers last quarter, it forecasted a growth of 6.2 million. BBC reports: Investors are worried about Netflix's growth potential in the face of increased competition from tech giants such as Apple, YouTube and Amazon, as well as traditional firms, which have started to invest more in online streaming. Disney, for example, plans to launch its own streaming service and stop licensing some of its material to Netflix.

In a letter to investors, Netflix called it a "strong but not stellar quarter," ending with about 130 million subscribers globally. The firm added just 670,000 subscribers in the U.S. -- far short of the more than one million it added in the second quarter of 2017. It added 4.5 million subscribers internationally, fewer than the two most recent quarters but up 8% year-on-year. However, it said its finances were strong. The company reported $3.9 billion in quarterly revenue, up 40% compared to the second quarter of 2017. Profits totaled $384.3 million, almost six times the figure during the same period a year ago.

Wave723 shares a report from IEEE Spectrum: Researchers at the U.S. Energy Department's Pacific Northwest National Laboratory (PNNL) and LCW Supercritical Technologies made use of readily available acrylic fibers to pull five grams of yellowcake -- a powdered form of uranium used to produce fuel for nuclear power reactors -- from seawater. The milestone, announced in mid-June, follows seven years of work and a roughly US $25 million investment by the federal energy agency. Another $1.15 million is being channeled to LCW as it attempts to scale up the technique for commercial use. The effort builds on work by Japanese researchers in the late 1990s and was prompted by interest in finding alternative sources of uranium for a future time when terrestrial sources are depleted. "[U]ranium in seawater shows up in concentrations of around 3.3 parts per billion," the report notes. "With a total volume estimated at more than 4 billion tons, there is around 500 times more uranium in seawater than in land-based sources."

Gunfighter shares a report from Defense News: President Donald Trump on Monday appeared to sign an executive order directing the Pentagon to create a new "Space Force," a move that could radically transform the U.S. military by pulling space functions variously owned by the Air Force, Navy and other military branches into a single independent service.

"I am hereby directing the Department of Defense and Pentagon to immediately begin the process necessary to establish a Space Force as the sixth branch of the armed forces," Trump said during a meeting of the National Space Council. "That's a big statement. We are going to have the Air Force and we are going to have the Space Force. Separate but equal. It is going to be something. So important," Trump added. "General Dunford, if you would carry that assignment out, I would be very greatly honored." Dunford responded in the affirmative, telling Trump, "We got you." The oddity of Trump's statement was that it was followed up with a White House readout that "contained no language related to the creation of a new military branch, leaving open the question of whether Trump has actually issued formal guidance to the military," reports Defense News. It is believed that Trump still needs the support of Congress to actually establish a space force.

The jobs market has reached what should be some kind of inflection point: there are now more openings than there are workers. From a report: April marked the second month in a row this historic event has occurred, and the gap is growing. According to the monthly Job Openings and Labor Turnover Survey released this week, there were just shy of 6.7 million open positions in April, the most recent month for which data are available. That represented an increase of 65,000 from March and is a record. The number of vacancies is pulling well ahead of the number the Bureau of Labor Statistics counts as unemployed. This year is the first time the level of the unemployed exceeded the jobs available since the BLS started tracking JOLTS numbers in 2000. As of April, the total workers looking and eligible for jobs fell to 6.35 million, a decrease from 6.58 million the previous month. The number fell further in May to 6.06 million, though there is no comparable JOLTS data for that month. Under normal circumstances, the mismatch would be creating a demand for higher wages. However, average hourly earnings rose just 2.7 percent annualized in May, up one-tenth of a point from April. Further reading: Why Nebraska has an amazing jobs market but nobody is moving there.

An anonymous reader quotes the Mercury News' report on Facebook's annual shareholder's meeting: On Thursday in Menlo Park, one investor compared the social network's poor stewardship of user data to a human rights violation. Another warned that scandal is not good for Facebook's bottom line. And one advised Chief Executive Officer Mark Zuckerberg to emulate George Washington, not Vladimir Putin, and avoid turning Facebook into a "corporate dictatorship." Facebook struggled to keep order, kicking one woman out of the meeting within the first few minutes for repeated interruptions. A plane zipped overhead pulling a banner that read "YOU BROKE DEMOCRACY" and advertising Freedom From Facebook, a group of privacy and anti-monopoly activists that are pressing the U.S. Federal Trade Commission to break up the company...

Zuckerberg repeated the same reassurances he used in front of U.S. and European lawmakers earlier this year: The company hasn't taken a broad enough view of its responsibility... "We're also very focused on being more transparent," Zuckerberg said, touting the fact that the company had just posted its policies on content moderation for the first time. Minutes earlier, the company announced that shareholder proposals for more transparency and oversight had failed, surprising no one. Zuckerberg controls the company through special stock that gives him more votes than other shareholders.
"Facebook said that just because the proposals were blocked, that didn't mean the company doesn't care about these issues."

A Tesla Model X has set the world record for heaviest tow by electric production passenger vehicle when it pulled a Boeing 787-9 Dreamliner at the Melbourne Airport in Australia. The video can be viewed on YouTube. Inverse reports: As probably expected, the plane far exceeds the Model X's recommended tow limit of around 5,000 pounds. In fact, the weight of the unloaded 787 with a minimal amount of fuel came closer to around 300,000 pounds. The airline pulled the Dreamliner around 1,000 feet down the tarmac. The stunt was part of a wider campaign around Qantas' new work with Tesla, which involves offering high-powered chargers at its Sydney, Melbourne, Brisbane and Adelaide facilities as well as offsetting miles for Tesla drivers that are also frequent flyer members.

In a blog post on Friday, Nvidia announced it is "pulling the plug" on the GeForce Partner Program (GPP) due to the company's unwillingness to combat "rumors" and "mistruths" about the platform. The GPP has only been active for a couple of months. It was launched as a way for gamers to know exactly what they're buying when shopping for a new gaming PC. "With this program, partners would provide full transparency regarding the installed hardware and software in their products," reports Digital Trends. From the report: Shortly after the launch, unnamed sources from add-in card and desktop/laptop manufacturers came forward to reveal that the program will likely hurt consumer choice. Even more, they worried that some of the agreement language may actually be illegal while the program itself could disrupt the current business they have with AMD and Intel. They also revealed one major requirement: The resulting product sports the label "[gaming brand] Aligned Exclusively with GeForce." As an example, if Asus wanted to add its Republic of Gamers (RoG) line to Nvidia's program, it wouldn't be allowed to sell RoG products with AMD-based graphics. Of course, manufacturers can choose whether or not to join Nvidia's program, but membership supposedly had its "perks" including access to early technology, sales rebate programs, game bundling, and more.

According to Nvidia, all it asked of its partners was to "brand their products in a way that would be crystal clear." The company says it didn't want "substitute GPUs hidden behind a pile of techno-jargon." Specifications for desktops and laptops tend to list their graphics components and PC gamers are generally intelligent shoppers that don't need any clarification. Regardless, Nvidia is pulling the controversial program because the "rumors, conjecture, and mistruths go far beyond" the program's intent.

An anonymous reader shares a report: If you were looking for a new graphics card for your PC over the last year, your search probably ended with you giving up and slinging some cusses at cryptocurrency miners. But now the supply of video cards is on the verge of rebounding, and I don't think you should wait much longer to pull the trigger on a purchase. Earlier this week, Digitimes reported that GPU vendors like Gigabyte, MSI, and others were expecting to see their card shipments plummet 40 percent month-over-month. The market for digital currencies like Bitcoin and Etherum is losing some of its momentum, and at the same time, large mining operations are pulling back on their investment in GPUs in anticipation of dedicated mining rigs (called ASICs) that are due out before the end of the year. These factors working in conjunction seem like they are leading to more supply, which in turn is forcing retailers to cut prices. For example, the Gigabyte GeForce GTX 1080 video card is selling on Amazon right now for $700. Other retailers even have it listed at the original MSRP of $600. These are the lowest prices of 2018 so far.

tomhath shares a report: Since the beginning of last year, 2000 Finns are getting money from the government each month -- and they are not expected to do anything in return. The participants, aged 25-58, are all unemployed, and were selected at random by Kela, Finland's social-security institution. Instead of unemployment benefits, the participants now receive $690 per month, tax free. Should they find a job during the two-year trial, they still get to keep the money. While the project is praised internationally for being at the cutting edge of social welfare, back in Finland, decision makers are quietly pulling the brakes, making a U-turn that is taking the project in a whole new direction. "Right now, the government is making changes that are taking the system further away from a basic income," Kela researcher Miska Simanainen told the Swedish daily Svenska Dagbladet.

"The BBC reports on something sure to impress your next date -- and possibly your last -- when you explain it," writes Slashdot reader dryriver. From the report: Scientists have turned their attention to investigating that most annoying of human habits -- the sound made when you crack your knuckles. The characteristic pop can be explained by three mathematical equations, say researchers in the US and France. Their model confirms the idea that the cracking sound is due to tiny bubbles collapsing in the fluid of the joint as the pressure changes. Surprisingly, perhaps, the phenomenon has been debated for around a century. Science student Vineeth Chandran Suja was cracking his knuckles in class in France when he decided to investigate.

"The first equation describes the pressure variations inside our joint when we crack our knuckles," he told BBC News. "The second equation is a well-known equation which describes the size variations of bubbles in response to pressure variations. And the third equation that we wrote down was coupling the size variation of the bubbles to ones that produce sounds." The equations make up a complete mathematical model that describes the sound of knuckle cracking, said Chandran Suja, who is now a postgraduate student at Stanford University in California. "When we crack our knuckles we're actually pulling apart our joints," he explained. "And when we do that the pressure goes down. Bubbles appear in the fluid, which is lubricating the joint -- the synovial fluid. "During the process of knuckle cracking there are pressure variations in the joint which causes the size of the bubbles to fluctuate extremely fast, and this leads to sound, which we associate with knuckle cracking.'' The study has been published in the journal Scientific Reports.

An anonymous reader quotes a report from Los Angeles Times: "Mad" Mike Hughes, the rocket man who believes the Earth is flat, propelled himself about 1,875 feet into the air Saturday before a hard landing in the Mojave Desert. He told the Associated Press that outside of an aching back he's fine after the launch near Amboy, Calif. The launch in the sparsely populated desert town about 150 miles east of Los Angeles -- was originally scheduled in November. It was scrubbed several times due to logistical issues with the Bureau of Land Management and mechanical problems that kept popping up. The 61-year-old limo driver converted a mobile home into a ramp and modified it to launch from a vertical angle so he wouldn't fall back to the ground on public land. For months he's been working on overhauling his rocket in his garage. It looked like Saturday might be another in a string of cancellations, given that the wind was blowing and his rocket was losing steam. Ideally, they wanted it at 350 psi for maximum thrust, but it was dropping to 340. Sometime after 3 p.m. PDT, and without a countdown, Hughes' rocket soared into the sky. Hughes reached a speed that Stakes estimated to be around 350 mph before pulling his parachute. Hughes was dropping too fast, though, and he had to deploy a second one. He landed with a thud and the rocket's nose broke in two places like it was designed to do.

An anonymous reader quotes a report from The Guardian: Children are increasingly finding it hard to hold pens and pencils because of an excessive use of technology, senior pediatric doctors have warned. An overuse of touchscreen phones and tablets is preventing children's finger muscles from developing sufficiently to enable them to hold a pencil correctly, they say. "Children are not coming into school with the hand strength and dexterity they had 10 years ago," said Sally Payne, the head pediatric occupational therapist at the Heart of England foundation NHS Trust. "Children coming into school are being given a pencil but are increasingly not be able to hold it because they don't have the fundamental movement skills. "To be able to grip a pencil and move it, you need strong control of the fine muscles in your fingers,. Children need lots of opportunity to develop those skills." Payne said the nature of play had changed. "It's easier to give a child an iPad than encouraging them to do muscle-building play such as building blocks, cutting and sticking, or pulling toys and ropes. Because of this, they're not developing the underlying foundation skills they need to grip and hold a pencil."

One promise of ride-hailing companies like Uber and Lyft was fewer cars clogging city streets. But studies suggest the opposite: that ride-hailing companies are pulling riders off buses, subways, bicycles and their own feet and putting them in cars instead . From a report: And in what could be a new wrinkle, a service by Uber called Express Pool now is seen as directly competing with mass transit. Uber and Lyft argue that in Boston, for instance, they complement public transit by connecting riders to hubs like Logan Airport and South Station. But they have not released their own specific data about rides, leaving studies up to outside researchers. And the impact of all those cars is becoming clear, said Christo Wilson, a professor of computer science at Boston's Northeastern University, who has looked at Uber's practice of surge pricing during heavy volume. "The emerging consensus is that ride-sharing (is) increasing congestion," Wilson said. One study included surveys of 944 ride-hailing users over four weeks in late 2017 in the Boston area. Nearly six in 10 said they would have used public transportation, walked, biked or skipped the trip if the ride-hailing apps weren't available. The report also found many riders aren't using hailed rides to connect to a subway or bus line, but instead as a separate mode of transit, said Alison Felix, one of the report's authors.

In some places, taps have been dry for over a year. People bathe their children with bottled water. A group of women has taken over water distribution from the city authorities. The future feared by millions of people across the world has already arrived in Mexico City , BuzzFeed News reports. From the report: In certain areas, people say taps go dry for months. Angry civilians have blocked off highways and squared off with riot police, wresting control of water distribution from the government. "Crime affects us deeply but if you don't have water, you can't do anything," said Marisol Fierro, part of a group of women in charge of delivering water to neighbors. Across the ocean, authorities in South Africa talk about Day Zero, when Cape Town is set to run out of water and the city is forced to shut off its taps. It has made headlines around the world, as people watch on with bated breath. But here in Iztapalapa, a sprawling, drab Mexico City borough where nearly 2 million people live, that day has already arrived, offering a window into what the future may hold for millions of people when the taps run dry. Police officers are sometimes forced to guard water trucks, popular targets for kidnappers who sell their contents for hefty prices. In other cities, politicians might promise expanded broadband, better health care, or higher wages to win votes, but in Mexico City, mayoral hopefuls have made simple access to water central to their campaigns. Reserved and quiet, Emma Pantaleon seems an unlikely protagonist at the front lines of this daily battle. Pantaleon joins Fierro and other women -- housewives who juggle child-rearing, house chores, and part-time jobs -- gathering water requests from their neighbors, coordinating trucks' routes with local authorities, and riding along to ensure the operation runs smoothly.

On a recent morning, she sat in the passenger seat of a water tanker as it revved its motor up a hill, dwarfing the dilapidated single-room houses along its path. When the driver swerved left and stepped on the brake, Pantaleon leaped out. It was a scene straight out of Mad Max: Fury Road. Pantaleon, 41, walked over to the nearest cinder block house and called out to its owner. As soon as Catalina Cortez opened the door, the driver and a helper marched in, pulling the truck's hose straight up to a plastic water storage tank taking up a third of the patio.

Samsung has rescued Opera Software's Opera Max data-saving, privacy-protecting Android app from oblivion and relaunched it today as Samsung Max. From a report: Norwegian tech company Opera, which first became known for its desktop browser when it launched in 1995, has offered mobile browser apps across various platforms for years. But in 2014, it launched the standalone Opera Max app for Android, designed to get its users more bang from their data plan, along with some VPN-like features. The app compresses data such as photos, music, and videos while promising "no noticeable loss of quality." Opera Max can also block background processes to conserve battery and data. The app was given a number of new features over the past few years, but last August the company revealed it was pulling the plug on Opera Max once and for all.

Corey Hutchinson, writing for ScreenRant: The MCU may be the biggest thing in Hollywood these days, but there's no denying that its overuse of CGI is becoming more and more noticeable. Don't get us wrong; for the most part, the MCU's CGI has been great, even spectacular at times. Even at its worst, it's nowhere near the bottom of the pile in terms of poor special effects in superhero movies. And no single MCU entry has come anywhere close to the awfulness that is Justice League. But when a superhero franchise is pulling in this much money and getting consistently glowing reviews, the bar has to be set high, and several of the MCU's latest offerings just aren't clearing it. It's worth noting that the MCU's CGI shortcomings are a relatively recent thing. There's very little to complain about when it comes to the special effects behind their Phase One movies. They all hold up surprising well, in fact, and the same goes for the vast majority of Marvel's Phase Two films. There's a few dicey moments in Avengers: Age of Ultron, but it wasn't really until Captain America: Civil War kicked off Phase Three that any negative attention was paid to the MCU's effects work.

Take a moment to rewatch the second Black Panther clip that was released to the public a few weeks ago. Specifically, hone in on the 45 second mark, where you see Nakia shooting two guys, the second of which is very obviously computer-generated. Why the hell would they even bother to CGI that, you ask?

More problems and controversy for Logan Paul, the YouTube star who caused a strong public backlash when he posted a video of a suicide victim in Japan. From a report: Google's video platform today announced that it would be pulling advertising temporarily from his video channel in response to a "recent pattern of behavior" from him. This is in addition to Paul's suspensions from YouTube's Preferred Ad program and its Originals series, both of which have been in place since January; and comes days after YouTube's CEO promised stronger enforcement of YouTube's policies using a mix of technology and 10,000 human curators.

Ford has developed a patent for a police car that issues tickets without even pulling you over. The same car could also use artificial intelligence to find good hiding spots to catch traffic violators (Warning: source may be paywalled; alternative source) and identify drivers by scanning license plates, tapping into surveillance cameras and wirelessly accessing government records. The Washington Post reports: The details may sound far-fetched, as if they belong in the science-fiction action flick "Demolition Man" or a new dystopian novel inspired by Aldous Huxley's "Brave New World," but these scenarios are grounded in a potential reality. They come from a patent developed by Ford and being reviewed by the U.S. government to create autonomous police cars. Ford's patent application was published this month. Although experts claim autonomous vehicles will make driving safer and more rule-bound, Ford argues in its application that in the future, traffic violations will never disappear entirely. "While autonomous vehicles can and will be programmed to obey traffic laws, a human driver can override that programming to control and operate the vehicle at any time," the patent's application says. "When a vehicle is under the control of a human driver there is a possibility of violation of traffic laws. Thus, there will still be a need to police traffic."

The patent application says that autonomous police vehicles don't necessarily replace the need for human police officers for catching traffic scofflaws. Some "routine tasks," such as issuing tickets for failure to stop at a stop sign, can be automated, the patent says, but other tasks that can't be automated will be left to people. The application, which was filed in July 2016 and includes elaborate diagrams depicting the autonomous police car interacting with its environment, says officers could be inside the vehicle at all times and reclaim control of the car when necessary. But the application also shows how an autonomous police vehicle could be able to carry out many tasks we associate with human officers.
