While "the vast majority" of lithium-ion batteries will never malfunction, lithium itself "is highly combustible and batteries made with it are subject to 'thermal runaway'," which can be triggered by damage -- or by bad design. An anonymous reader quotes the San Jose Mercury News:
Battery and electronics manufacturers take numerous steps to try to mitigate such dangers... But while the industry has tried to make lithium-ion batteries safer, 'the technology itself isn't foolproof,' said Ravi Manghani, director of energy storage research at GTM Research... And there's reason to think that the problem could get worse before it gets better. Consumer demand for devices that are ever more powerful and longer lasting has encouraged manufacturers to make batteries that can hold even more charge. To do that, they typically pack the battery cells closer and closer together...
Since June of this year, educational toy company Roylco recalled 1,400 light tables designed for kids... Razor, Swagway and some eight other manufacturers recalled a total of 500,000 hoverboards. And HP and Sony between them recalled more than 42,000 notebook computers. All for similar reasons -- lithium-ion batteries that either had caught fire or which have posed a fire hazard... Other notorious examples include the several different Tesla Model S's that have caught fire, typically after crashes compromised their battery packs, and Sony's wide-scale recall a decade ago of the batteries that powered its Vaio and other laptop computers.

First-time submitter Big O Notation shares "an honest review about the new Ubuntu Bash" that shipped with the Windows 10 Anniversary Update. While it's still officially beta, most of the commands work as expected, and it includes popular programs like the Pico text editor. Here's some of the review's highlights:
Pros: You can also manage and manipulate other files inside your entire Hard Disk, even those outside of your Linux home directory.
Cons: Even if you chmod something properly, when you use ls -l the Bash would not show the correct permissions. [And] if you try to create a Folder in your Linux Home Directory by using the Windows GUI, it would be impossible to read and manage it. Don't try this at home.
Microsoft says they've included the Windows Subsystem for Linux
primarily as "a tool for developers -- especially web developers and those who work on or with open source projects." One Scandinavian developer has even tried running X on Bash on Ubuntu on Windows, reporting success running simpler programs like xcalc and xclock, as well as Gnome Control Center and xeditor and SciTE. "Things start to fall apart if you try to get more ambitious, though."Read Replies (0)

Earlier this month Mashable wrote "it's now even more obvious what [Apple] is working to bring to the masses, and it's probably not, as some rumors have indicated, virtual reality." They cited CEO Tim Cook's recent predictions that augmented reality "is going to become really big" -- he said it again on Thursday -- and BuzzFeed noted that Apple "has quietly put into place the components of what could prove to be an AR ecosystem:
The iPhone 7 Plus has...a two-camera system capable of gathering stereoscopic data and generating image depth maps... In Apple Watch, the company has a spatially-aware, wearable device outfitted with an accelerometer and GPS. In its new AirPod wireless earphones, Apple essentially has a pair of diminutive, spatially-aware microcomputers -- each one with an Apple W1 wireless chip (the company's first), two accelerometers, two optical sensors, beam-forming microphones, and an antenna... And sources tell BuzzFeed News that the company has recently been taking meetings with immersive content companies like Jaunt.
Their article also lists AR companies that Apple's bought over the last three years -- plus their patents for a "head-mounted display" and a "peripheral treatment for head-mounted displays." BGR adds that Tim Cook "likes to tease future products," and points out that Cook has even said Apple is working on AR features "behind the curtain". This casts a new light on those rumors of an all-glass case for next year's iPhone 8. Will the whole body of the phone become part of an Augmented Reality display system? (And could AR also explain Apple's aggressive push for wireless headphones?)Read Replies (0)

For the first time ever, secure HTTPS encryption was used for over half the pageloads served to Mozilla users, representing a big milestone for encryption. TechCrunch reports on the telemetry data tweeted by the Head of Let's Encrypt:
Mozilla, which is one of the organizations backing Let's Encrypt, was reporting that 40% of page views were encrypted as of December 2015. So it's an impressively speedy rise...
The Let's Encrypt initiative, which exited beta back in April, is doing some of that work by providing sites with free digital certificates to help accelerate the switch to HTTPS. According to [co-founder Josh] Aas, Let's Encrypt added more than a million new active certificates in the past week -- which is also a significant step up. In the initiative's first six months (when still in beta) it only issued around 1.7 million certificates in all.
The "50% HTTPS" figure is just a one-day snapshot, and it's from "only a subset of Firefox users who are running Mozilla's telemetry browser...not default switched on for most Firefox users (only for users of pre-release Firefox builds)."
But the biggest caveat is it's only counting Firefox users, which in July represented just 7.7% of web surfers (according to Statista), behind both Chrome (49.5%) and Safari (13.68%) -- but also ahead of Internet Explorer (5.4%) and Opera (5.99%).Read Replies (0)

From a report on Inverse: When Mercedes-Benz starts selling self-driving cars, it will choose to prioritize driver safety over pedestrians', a company manager has confirmed. The ethical conundrum of how A.I.-powered machines should act in life-or-death situations has received more scrutiny as driverless cars become a reality, but the car manufacturer believes that it's safer to save the life you have greater control over. "You could sacrifice the car. You could, but then the people you've saved initially, you don't know what happens to them after that in situations that are often very complex, so you save the ones you know you can save," said Christoph von Hugo, Mercedes' manager of driver assistance systems. "If you know you can save at least one person, at least save that one. Save the one in the car. This moral question of whom to save: 99 percent of our engineering work is to prevent these situations from happening at all. We are working so our cars don't drive into situations where that could happen and [will] drive away from potential situations where those decisions have to be made."As long as they are better at driving and safety than humans, it is a progress, in my opinion.Read Replies (0)

Apple will make all iPhone 4 models, the late 2010 13-inch MacBook Air, third-generation AirPort Extreme, and mid-2009 AirPort Time Capsule obsolete come October 31, MacRumor claims, citing a different report. From the report: Apple products on the vintage and obsolete list are no longer eligible for hardware service, beyond a few exceptions. Apple defines vintage products as those that have not been manufactured for more than five years but less than seven years ago, while obsolete products are those that were discontinued more than seven years ago. Each of the products added were released between 2009 and 2010. The report specifically pertains to Apple's vintage and obsolete products list in Japan, but the new additions will more than likely extend to the United States, Australia, Canada, and the rest of the Asia-Pacific and Europe regions.Read Replies (0)

Kate Lunau, reporting Motherboard:Greenland isn't happy about being treated as a dumping ground for abandoned US military bases established at the height of the Cold War -- and in a newspaper editorial, it's calling on Denmark to deal with the mess left behind by the Americans, since the Danish long ago took responsibility for them. This editorial notes that, after decades, Greenland is "losing its patience." One of the abandoned bases, called Camp Century, is full of nasty chemicals and some radioactive material, as Motherboard previously reported. At Camp Century, which was built in 1959, soldiers called "Iceworms" practiced deployment of missiles against Russia and literally lived inside the ice. When the US decommissioned the base in the 1960s, the military left basically everything behind, thinking that its waste would stay locked up in the Greenland ice sheet forever. Well, climate change has made that unlikely. Melting ice threatens to expose all kinds of toxic debris in decades to come, and Greenland wants it cleaned up, now.Read Replies (0)

Slashdot reader schwit1 reports that the Obama administration "is contemplating an unprecedented cyber covert action against Russia in retaliation for alleged Russian interference in the American presidential election," according to U.S. intelligence officials who spoke to NBC News:
Current and former officials with direct knowledge of the situation say the CIA has been asked to deliver options to the White House for a wide-ranging "clandestine" cyber operation designed to harass and "embarrass" the Kremlin leadership. The sources did not elaborate on the exact measures the CIA was considering, but said the agency had already begun opening cyber doors, selecting targets and making other preparations for an operation. Former intelligence officers told NBC News that the agency had gathered reams of documents that could expose unsavory tactics by Russian President Vladimir Putin.
Vice President Joe Biden told "Meet the Press" moderator Chuck Todd on Friday that "we're sending a message" to Putin and that "it will be at the time of our choosing, and under the circumstances that will have the greatest impact." When asked if the American public will know a message was sent, the vice president replied, "Hope not."
Not mounting a response would weaken U.S. credibility, one senior U.S. official said, while others said hundreds of millions of dollars has been allocated to the team mounting the attacks. Thursday US officials familiar with the investigation told CNN there was "mounting evidence" that Russia was supplying leaked emails to WikiLeaks, and last week in a conference call organized by the Clinton campaign, former Acting CIA Director Mike Morrell said it was "absolutely clear... WikiLeaks and Guccifer 2 are working with the Russians on this."Read Replies (0)

In the middle of a discussion about the pros and cons of statins, Sir Rory Collins, the head of clinical trials at Oxford University, noted that If you want a career in medicine these days you're better off studying mathematics or computing than biology. A report on BBC adds: It is a nice one-liner, but I didn't think much more about it until a few days later, when I found myself sitting in a press conference to mark the launch of a new initiative on cancer. Rubbing shoulders on the panel with the director of the Institute of Cancer Research, Professor Paul Workman, was a scientist I didn't recognise, but it soon became clear this was exactly what Sir Rory had had in mind. Dr Andrea Sottoriva is an astrophysicist. He has spent much of his career searching for Neutrinos -- the elusive sub-atomic particles created by the fusion of elements in stars like our sun -- at the bottom of the ocean, and analysing the results of atom smashing experiments with the Large Hadron Collider at Cern in Geneva. "My background is in computer science, particularly as it applies to particle physics," he told me when we met at the ICR's laboratories in Sutton. So why cancer? The answer can be summed up in two words: big data. What Dr Sottoriva brings to the fight against cancer is the expertise in mathematical modelling needed to mine the vast treasure trove of data the information revolution has brought to medicine. "The exciting thing is that we can apply all the new analytical techniques we've developed in physics to biology," he says. "So we have all these new quantitative technologies that allow us to process an enormous amount of data, and all of a sudden we can start to apply that to implement the paradigm of physics in biology."Read Replies (0)

Instacart says it is adjusting planned changes to its pay structure for full-service shoppers. The change of heart comes after independent contractors threatened to boycott the grocery delivery startup's plans to replace tips with an optional 10 percent fee collected by the company. From a TechCrunch report: CEO Apoorva Mehta stressed that the decision came from customers looking to continue tipping, rather than complaints from shoppers, which he called a small group that was "very vocal" about the change. However, following removing tips, Instacart received some backlash from shoppers who said they were losing significant portions of their earnings. The backlash went so far as to inspire a boycott among some shoppers, though again Mehta said that this was not the primary cause for returning tipping. [...] Originally, the company sought to raise the overall earnings payout per delivery while removing tips, which was an attempt to make earnings more reliable instead of burst-y as a result of tips. Top shoppers, however, accustomed to getting larger tips because of their performance were concerned that they would lose a significant portion of their earnings. The vocal minority, it seems, was loud enough -- and perhaps so was the customer base -- that Instacart had to reverse course. Update: 10/15 21:25 GMT by M :Title updated to fix a typo. I regret the error.Read Replies (0)
