Public Service Announcement: You Should Not Force Quit Apps on iOS (daringfireball.net) 135

John Gruber, writing for DaringFireball: The single biggest misconception about iOS is that it's good digital hygiene to force quit apps that you aren't using. The idea is that apps in the background are locking up unnecessary RAM and consuming unnecessary CPU cycles, thus hurting performance and wasting battery life. That's not how iOS works. The iOS system is designed so that none of the above justifications for force quitting are true. Apps in the background are effectively "frozen", severely limiting what they can do in the background and freeing up the RAM they were using. iOS is really, really good at this. It is so good at this that unfreezing a frozen app takes up way less CPU (and energy) than relaunching an app that had been force quit. Not only does force quitting your apps not help, it actually hurts. Your battery life will be worse and it will take much longer to switch apps if you force quit apps in the background. [...] In fact, apps frozen in the background on iOS unfreeze so quickly that I think it actually helps perpetuate the myth that you should force quit them: if you're worried that background apps are draining your battery and you see how quickly they load from the background, it's a reasonable assumption to believe that they never stopped running. But they do. They really do get frozen, the RAM they were using really does get reclaimed by the system, and they really do unfreeze and come back to life that quickly.

End of the Line For Remix OS as Jide Shifts Its Energy Towards the Enterprise (neowin.net) 29

An anonymous reader shares a report: It was only in July last year that Remix OS, an Android-based operating system for PCs, was bumped up to Version 3.0, which featured Android 6.0 Marshmallow under the hood. In fact, news of the upgrade came hot on the heels of an announcement from Chuwi with regards to the release of its $239 Vi10 Plus tablet that dual-booted Remix OS and Windows 10. A little over a month later, Jide Technology then followed up with a "developer preview" of the OS leveraging Android 7.0 Nougat. However, after a somewhat brief period of existence of just a few years, the company has announced that it is shifting its focus away from the consumer segment to the enterprise. In a statement on its website, Jide stated that: "Over the past year, we received an increasing number of inquiries from enterprises in various industries, and began helping them build great tools for their organizations by leveraging Jide software and hardware. We see huge potential in the role that Jide can play to revolutionize how these businesses operate. And given our existing resources, we decided to focus our company efforts solely on the enterprise space moving forward."

Visa Considers Extending 'War on Cash' Business Incentives Outside US (cnbc.com) 303

Visa is hoping to extend its "war on cash" agenda to businesses in the U.K. after announcing new incentives for U.S. businesses to go cashless. From a report: The payment technology company revealed on Wednesday that it was launching a "cashless challenge" which would see 50 U.S. businesses receive $10,000 each to help them convert to a cashless payment model. It is now aiming to roll the model out to the U.K., though is yet to set a timeframe for the launch, a Visa spokesperson confirmed to CNBC Friday. Under the scheme, businesses in the U.S. are invited to submit plans outlining what going cashless might mean for them, their employees and their customers. Recipients of the award will then be required to use the lump sum to upgrade their point-of-sale systems so they are completely cashless. Any remaining money can be put towards marketing, the company said. "We're declaring a war on cash," Andy Gerlt, a spokesman for Visa, said in the announcement Wednesday.

Facebook Envisions New Campus With Affordable Housing Units (sfgate.com) 123

An anonymous reader writes: "In a few years, families could be living at Facebook," quips CNET. The Bay Area Newsgroup reports that Facebook is proposing a new campus with facilities open to the public "to address long-neglected community needs and to accommodate its burgeoning workforce." But the San Francisco Chronicle sees more than just new buildings. "Implicit in the tech company's announcement is Facebook's belief that it can solve some of the area's most pressing issues, including traffic congestion, demand for affordable housing and a lack of transit options. By opening the campus and some of its facilities to the public, Facebook is also heading off a common criticism lobbed at wealthy tech firms: that they move into cities, drive up the cost of living, displace area residents and then do little to give back."

Facebook will offer 15% of the housing -- about 225 units -- at "below market rates." They're also promising to invest tens of millions of dollars in improvements to nearby Highway 101 and to "catalyze regional transit investment," according to Facebook's vice president of global facilities and real estate. The Chronicle notes that the campus's open-to-the-public pharmacy and grocery store "would also solve the issue of a lack of food retailers in that part of the city, where the nearest large store is a Safeway 4 miles away -- a trip that can take up to 40 minutes during rush hour, according to Google Maps."

The EFF's 'Let's Encrypt' Plans Wildcard Certificates For Subdomains (letsencrypt.org) 110

Long-time Slashdot reader jawtheshark shares an announcement from the EFF's free, automated, and open TLS certificate authority at LetsEncrypt.org: Let's Encrypt will begin issuing [free] wildcard certificates in January of 2018... A wildcard certificate can secure any number of subdomains of a base domain (e.g. *.example.com). This allows administrators to use a single certificate and key pair for a domain and all of its subdomains, which can make HTTPS deployment significantly easier.
58% of web traffic is now encrypted, Let's Encrypt reports, crediting in part the 47 million domains they've secured since December of 2015. "Our hope is that offering wildcards will help to accelerate the Web's progress towards 100% HTTPS," explains their web page, noting that they're announcing the wild card certificates now in conjunction with a request for donations to support their work.

Elon Musk Promises World's Biggest Lithium Ion Battery To Australia (cnn.com) 272

Elon Musk is following through on his promise to solve an energy crisis in Australia. From a report: His electric car company, Tesla, has teamed up with a French renewable energy firm and an Australian state government to install the world's largest lithium ion battery. Paired up with a wind farm in the state of South Australia, the battery will be three times more powerful than the next biggest in the world, Musk said at a news conference in the city of Adelaide on Friday. "If South Australia's willing to take a big risk, then so are we," he said. The announcement comes after billionaire entrepreneur Mike Cannon-Brookes threw down the gauntlet to Musk in March, asking if Tesla was serious when it claimed it could quickly end blackouts in South Australia. "Tesla will get the system installed and working 100 days from contract signature or it is free. That serious enough for you?" Musk wrote on Twitter at the time.

Petya Ransomware Authors Demand $250,000 In First Public Statement Since Attack (theverge.com) 59

An anonymous reader quotes a report from The Verge: The group responsible for last week's globe-spanning ransomware attack has made their first public statement. Motherboard first spotted the post, which was left on the Tor-only announcement service DeepPaste. In the message, the Petya authors offer the private encryption key used in the attack in exchange for 100 bitcoin, the equivalent of over $250,000 at current rates. Crucially, the message includes a file signed with Petya's private key, which is strong evidence that the message came from the group responsible for Petya. More specifically, it proves that whoever left the message has the necessary private key to decrypt individual files infected by the virus. Because the virus deleted certain boot-level files, it's impossible to entirely recover infected systems, but individual files can still be recovered. The message also included a link to a chat room where the malware authors discussed the offer, although the room has since been deactivated.

Volvo Says It Will Only Make Electric and Hybrid Cars Starting in 2019 (npr.org) 240

Volvo has announced that starting in 2019, all of the new models it produces will be electric or hybrid. From a report: "This announcement marks the end of the solely combustion engine-powered car," said Hakan Samuelsson, Volvo president and chief executive, in a statement. "Volvo Cars has stated that it plans to have sold a total of 1 million electrified cars by 2025. When we said it we meant it. This is how we are going to do it." The move makes Volvo the first traditional automaker to set a date to phase out cars powered only by internal combustion engines, Reuters reports. The company said it will launch five fully electric cars between 2019 and 2021. Three of these will be Volvos, and two will be sold under the company's Polestar "electrified performance brand."

Linux Kernel 4.12 Officially Released (softpedia.com) 55

prisoninmate quotes Softpedia: After seven weeks of announcing release candidate versions, Linus Torvalds today informs the Linux community through a mailing list announcement about the general availability of the Linux 4.12 kernel series. Development on the Linux 4.12 kernel kicked off in mid-May with the first release candidate, and now, seven weeks later we can finally get our hands on the final release... A lot of great improvements, new hardware support, and new security features were added during all this time, which makes it one of the biggest releases, after Linux 4.9...

Prominent features of the Linux 4.12 kernel include initial support for AMD Radeon RX Vega graphics cards, intial Nvidia GeForce GTX 1000 "Pascal" accelerated support, implementation of Budget Fair Queueing (BFQ) and storage-I/O schedulers, more MD RAID enhancements, support for Raspberry Pi's Broadcom BCM2835 thermal driver, a lot of F2FS optimizations, as well as ioctl for the GETFSMAP space mapping ioctl for both XFS and EXT4 filesystems.

Linus said in announcing the release that "I think only 4.9 ends up having had more commits," also noting that 4.9 was a Long Term Support kernel, whereas "4.12 is just plain big."

"There's also nothing particularly odd going on in the tree - it's all just normal development, just more of it than usual."

23 Years Of The Open Source 'FreeDOS' Project (linuxjournal.com) 123

Jim Hall is celebrating the 23rd birthday of the FreeDOS Project, calling it "a major milestone for any free software or open-source software project," and remembering how it all started. An anonymous reader quotes Linux Journal: If you remember Windows 3.1 at the time, it was a pretty rough environment. I didn't like that you could interact with Windows only via a mouse; there was no command line. I preferred working at the command line. So I was understandably distressed in 1994 when I read via various tech magazines that Microsoft planned to eliminate MS-DOS with the next version of Windows. I decided that if the next evolution of Windows was going to be anything like Windows 3.1, I wanted nothing to do with it... I decided to create my own version of DOS. And on June 29, 1994, I posted an announcement to a discussion group... Our "PD-DOS" project (for "Public Domain DOS") quickly grew into FreeDOS. And 23 years later, FreeDOS is still going strong! Today, many people around the world install FreeDOS to play classic DOS games, run legacy business software or develop embedded systems...

FreeDOS has become a modern DOS, due to the large number of developers that continue to work on it. You can download the FreeDOS 1.2 distribution and immediately start coding in C, Assembly, Pascal, BASIC or a number of other software development languages. The standard FreeDOS editor is quite nice, or you can select from more than 15 different editors, all included in the distribution. You can browse websites with the Dillo graphical web browser, or do it "old school" via the Lynx text-mode web browser. And for those who just want to play some great DOS games, you can try adventure games like Nethack or Beyond the Titanic, arcade games like Wing and Paku Paku, flight simulators, card games and a bunch of other genres of DOS games.

On his "Open Source Software and Usability" blog, Jim says he's been involved with open source software "since before anyone coined the term 'open source'," and first installed Linux on his home PC in 1993. Over on the project's blog, he's also sharing appreciative stories from FreeDOS users and from people involved with maintaining it (including memories of early 1980s computers like the Sinclair ZX80, the Atari 800XL and the Coleco Adam). Any Slashdot readers have their own fond memories to share?

Japan Wants To Put a Man On the Moon, Accelerating Asian Space Race (cnn.com) 74

Japan plans to put a man on the moon around 2030, according to a new proposal by the government's Japan Aerospace Exploration Agency (JAXA). From a report: It is the first time JAXA has revealed an intention to send Japanese astronauts beyond the International Space Station, and it will mostly likely be part of an international mission, the agency said. The announcement from Japan is just the latest in a series of ambitious space exploration plans by Asian countries, with the increasing competition for space-related power and prestige in the region echoing that of the Cold War space race of the mid-20th century. In December 2016, China announced plans to land a rover on Mars by 2020 as well as a manned mission to the Moon at some point in the future.

Sony Will Start Pressing Vinyl Records After 28-Year Hiatus (fortune.com) 136

Sony said this week it will begin pressing vinyl records again, ending an almost three-decade hiatus. A dramatic increase in demand for vinyl music in recent years prompted the move, the company said. From a report: After a 28-year hiatus, Sony announced this week that it plans to open a new facility in Japan dedicated to pressing vinyl records. It's a back-to-the-future announcement at a time when the true digital music revolution -- downloaded and streaming via always-on Internet connectivity -- has quickly grown to dominate listening habits. According to Japan's recording industry association, the country produced nearly 200 million records per year in the mid-1970s. That's unlikely to return. But while many of us have been content to wirelessly download our music, a surprising number of people are going to the store -- or Amazon.com, let's be honest -- and purchasing a vinyl record, sleeve and all.

New Study Finds How Much Sleep Fitbit Users Really Get 75

Fitbit has published the results of a study that uses their longitudinal sleep database to analyze millions of nights of Sleep Stages data to determine how age, gender, and duration affect sleep quality. (Sleep Stages is a relatively new Fitbit feature that "uses motion detection and heart rate variability to estimate the amount of time users spend awake in light, deep, and REM sleep each night.") Here are the findings: The average Fitbit user is in bed for 7 hours and 33 minutes but only gets 6 hours and 38 minutes of sleep. The remaining 55 minutes is spent restless or awake. That may seem like a lot, but it's actually pretty common. That said, 6 hours and 38 minutes is still shy of the 7+ hours the the CDC recommends adults get. For the second year in a row Fitbit data scientists found women get about 25 minutes more sleep on average each night compared to men. The percentage of time spent in each sleep stage was also similar -- until you factor in age. Fitbit data shows that men get a slightly higher percentage of deep sleep than women until around age 55 when women take the lead. Women win when it comes to REM, logging an average of 10 more minutes per night than men. Although women tend to average more REM than men over the course of their lifetime, the gap appears to widen around age 50.

Trump Picks Republican To Fill Empty Commissioner Seat At FCC (arstechnica.com) 71

An anonymous reader quotes a report from Ars Technica: The Federal Communications Commission's empty slots are about to be filled. President Donald Trump will nominate Republican Brendan Carr to the FCC's fifth and final commissioner position, the White House announced last night. Carr served as FCC Commissioner Ajit Pai's Wireless, Public Safety, and International Legal Advisor for three years. After Trump elevated Pai to the chairmanship in January, Pai appointed Carr to become the FCC's general counsel. "Brendan has a distinguished record of public service, having worked at the agency for over five years, including most recently as the FCC's General Counsel," Pai said after the White House announcement. "In particular, Brendan's expertise on wireless policy and public safety will be a tremendous asset to the Commission."

Sorry, But Anonymous Has No Evidence That NASA Has Found Alien Life (popsci.com) 166

From a Popular Science article: In a new video, the hacker group known as Anonymous claims that NASA has discovered alien life. But before you freak out, let's talk. Sadly, the group of activists and hacktivists doesn't seem to have found any new evidence to support their extraordinary claim. The video is mainly based on NASA quotes taken out of context, and what appear to be videos and information from conspiracy theory websites. The crux of the argument is based on something Thomas Zurbuchen, NASA's associate administrator for the Science Mission Directorate, said during a hearing in April. These sorts of hearings are organized to educate the House Science Committee on the latest research in a particular field of study. During this one, Zurbuchen said: "Taking into account all of the different activities and missions that are specifically searching for evidence of alien life, we are on the verge of making one of the most profound, unprecedented, discoveries in history." That's the quote Anonymous is pegging their video on. But if you watch his opening statement, he actually explains his reasoning just before he gets to that part. He mentions the Mars 2020 rover, which will look for signs of past life on the red planet. The Europa Clipper mission is slated to search for conditions suitable to life on Jupiter's ocean-filled moon. In a statement, Zurbuchen said, "While we're excited about the latest findings from NASA's Kepler space observatory, there's no pending announcement regarding extraterrestrial life. For years NASA has expressed interest in searching for signs of life beyond Earth. We have a number of science missions that are moving forward with the goal of seeking signs of past and present life on Mars and ocean worlds in the outer solar system. While we do not yet have answers, we will continue to work to address the fundamental question, 'are we alone?'"

Google Replaces Gchat With Hangouts Today (axios.com) 178

An anonymous reader shares a report: The day dreaded by stubborn office workers around the country has finally arrived. At some point today, Google will replace its Google Talk feature in Gmail -- known colloquially to most of the world as Gchat -- with Google Hangouts. The reasoning: Google's announcement of the switch back in March touts Hangouts' better features and integration with other Google products over the barebones Gchat, which launched way back in 2005.

Tesla Is 'In Talks' To Build a Factory In China (qz.com) 55

Tesla confirmed yesterday that it is "in talks" with the municipal government of Shanghai to manufacture its vehicles in the country. Tesla said in a statement: "Tesla is working with the Shanghai Municipal Government to explore the possibility of establishing a manufacturing facility in the region to serve the Chinese market. As we've said before, we expect to more clearly define our plans for production in China by the end of the year. Tesla is deeply committed to the Chinese market, and we continue to evaluate potential manufacturing sites around the globe to serve the local markets. While we expect most of our production to remain in the U.S., we do need to establish local factories to ensure affordability for the markets they serve." Quartz reports: The announcement follows more than a year of speculation that the electric-vehicle maker would set up shop in China, and confirms that Tesla is altering its China strategy away from merely exporting vehicles in order to reach more Chinese consumers. Earlier this year, Musk made a stealth visit to China to visit Wang Yang, one of the nation's highest-ranking officials, to discuss Tesla's plans. Tesla has been selling vehicles in China since 2014, but to date, its share of the electric vehicle market remains marginal, at just 2% as of June 2016, according to trade blog CleanTechnica. There are several reasons for this, one of which is price. Tesla currently exports its vehicles to China, and the government places an import tax of 50% on Tesla cars. The sticker price for the most simple Model S in China is $104,972, compared to $69,500 in the US.

Google Will Now Hide Personal Medical Records From Search Results (betanews.com) 34

Mark Wilson, writing for BetaNews: Google has updated its search policies without any sort of fanfare. The search engine now "may remove" -- in addition to existing categories of information -- "confidential, personal medical records of private people" from search results. That such information was not already obscured from search results may well come as something of a surprise to many people. The change has been confirmed by Google, although the company has not issued any form of announcement about it.

Trump Promises a Federal Technology Overhaul To Save $1 Trillion (technologyreview.com) 381

New submitter threc shares a report from MIT Technology Review: The tech world descended on Washington, D.C. yesterday to attend a tech summit at the White House. According to MIT Technology Review associate editor Jamie Condliffe: "Trump suggested he might relax his stance on immigration as a way to get tech leaders to help his cause. 'You can get the people you want,' he told the assembled CEOs. That sweetener may be a response to a very vocal backlash in the tech world against the administration's recent travel bans. Trump may hope that his business-friendly stance will offer enough allure: if tech giants scratch his back, he may later deign to scratch theirs." The report continues: "'Our goal is to lead a sweeping transformation of the federal government's technology that will deliver dramatically better services for citizens,' said Trump at the start of his meeting with the CEOs, according to the Washington Post. 'We're embracing big change, bold thinking, and outsider perspectives.' The headline announcement from the event was Trump's promise to overhaul creaking government computing infrastructure. According to Jared Kushner, the president's son-in-law and advisor, there's much to be done: federal agencies have over 6,000 data centers that could be consolidated, for instance, while the 10 oldest networks in use by the government are all at least 39 years old. The upgrade, said Trump, could save the country $1 trillion over the next 10 years."
