It seems like everyone's curious about how the Apple Watch 4 detects falls. The Washington Post reports: In the interest of science, I've tried jumping off ledges and throwing myself onto furniture. The thing never went off. (The feature is on by default only for people older than 65, but I turned mine on.) It's possible, even likely, that the Watch could tell I was faking.

What's important is actual falls, not stunts. Apple says it studied the falls of 2,500 people of varying ages. Yet the company hasn't said how often it catches real falls or sets off false alarms. This isn't like claiming the "best camera ever" on a smartphone -- if Apple wants us to think of its products as life aids, it ought to show us the data. Even better: peer-reviewed studies. Apple's disclaimer says: "Apple Watch cannot detect all falls. The more physically active you are, the more likely you are to trigger Fall Detection due to high impact activity that can appear to be a fall."
But there's now also a new video by the Wall Street Journal that tests the watch's fall-detecting capabilities with a professional stuntwoman. Hot Hardware reports: The Wall Street Journal found that the Apple Watch did a very good job of detecting a serious fall while ignoring insignificant or outright fake falls. The stunt double performed a series of falls that are similar to falls in the slides that Apple showed in its keynote explaining the feature. In the testing, the watch was able to identify those falls and offer to call emergency services.

The most interesting part is that even though the stunt woman pulled some serious fake falls, complete with Hollywood-style tumbling down a hill, the Apple Watch was able to figure out if the fall was fake and didn't offer to call emergency services.
The Journal's reporter credits the watch's gyroscope and accelerometer, which can monitor numerous factors including both speed and wrist trajectory. Their conclusion?

"Turns out the Apple Watch really does know when you're just playing around."

"I've seen this 'Smart Compose' feature described publicly with a range of adjectives," writes Lauren Weinstein, "including intrusive, wonderful, invasive, creepy, accurate, loony, mistaken, helpful, misguided -- well, you get the point, opinions are all over the map...." My foundational complaint here isn't that Google deployed Smart Compose, but rather that they enabled it by default without providing users even basic related information, including the all important "How the hell do I turn this damned thing off?" -- the very question filling my inbox of late!

So here's how you turn it off. It's easy, IF you know how.
One anonymous reader has another solution. "I'm just using Gmail in HTML-only mode now. Its actually far more usable than their new crap and I'm quite fond of the older look anyway." You could also just stop using Gmail -- but Weinstein thinks it's easier to disable the "Smart Compose feature.

"With the understanding that Google has great AI and is itching to use it whenever and wherever possible, I don't really need it analyzing my email drafts as I type them. At least in my case, its proposed wordings are nearly always -- what's the technical term? -- oh yes, WRONG.

"And the predictions intrusively and continuously interrupt my flow of typing as each one needs to be individually bypassed."

An anonymous reader quotes Computerworld: Slack is building a new analytics tool to offer businesses greater insights into how their teams collaborate, part of the company's plans to make better use of the data created within its popular chatapp. "We are hoping to build a set of insights that help you understand not only how Slack is being used, but how your company is collaborating and functioning," said Jamie DeLanghe, head of Slack's Search, Learning and Intelligence (SLI) team... Slack's SLI division was created in 2016 to help make better use of the reams of information being created and stored as Slack adoption grows. The New York-based team is responsible for enhancing search functionality and developing the Slack "work graph," which ties together data on a users' behavior and interactions to enable more accurate recommendations.

The team is also tasked with building out Slack's analytics capabilities to highlight areas for improvement based on information about how teams work together. Analytics is something Slack's rivals are focused on, too: Google launched Work Insights to track adoption of its G Suite software and identify which teams are collaborating frequently using tools such as Hangouts Chat. And Microsoft has launched Workplace Analytics, which performs a similar function for its Office 365 tools.

The contest's organizers are encouraging people to play and rate the free games, and encourage their friends to join in the fun (or to donate more prize money or other prizes). They're dedicating this year's competition to the memory of Stu Galley, who co-founded the pioneering text adventure company Infocom back in 1979 with his classmates from MIT. Infocom went on to create everything from Zork to a popular Hitchhiker's Guide to the Galaxy game, and Stu is credited as the driving force behind text adventures like Moonmist, Seastalker, and The Witness.

Tesla's model 3 is now one of the five top-selling sedans in America (while sales of the Mercedes-Benz C-Class are down 28 percent through September), Bloomberg reports. Elon Musk tweeted out a link to their article on Thursday -- but it was his other tweet, a satirical criticism of the SEC, that made headlines. MarketWatch reports: Tesla shares ended 7% lower on Friday as Wall Street reacted to Musk's tweet seemingly out of nowhere late Thursday about the "Shortseller Enrichment Commission." Musk also tweeted that day that short sellers were "value destroyers" and should be illegal. Friday's losses for Tesla "produced more than half a billion in paper profit for the shorts," S3 Partners LLC, which tracks real-time short interest data, said in a note. Since news of the Musk's settlement with the SEC, shorts are up $941 million, S3 Partners said. "Clearly short positions are building in the wake of strong selling by longs, as Musk demonstrates a refusal to keep away from controversy," the note said.
The article notes that last Saturday the SEC settled charges that Musk misled investors with a tweet about taking Tesla private. "Terms of the settlement included requiring Tesla to rein in Musk's social-media communications, but it was unclear when Tesla intends to implement that.... The settlement has yet to be court-approved."

On Friday Musk was back on point, tweeting out the news that Tesla owners "can refer someone to buy a Tesla & get any image they want laser etched in glass & sent to deep space for millions of years."

"Linux runs the world, right? So we want to make sure that things are secure," says Linux kernel maintainer Greg Kroah-Hartman. When asked in a new video interview which bug makes them most angry, he first replies "the whole Spectre/Meltdown problem. What made us so mad, in a way, is we were fixing a bug in somebody else's layer!" One also interesting thing about the whole Spectre/Meltdown is the complexity of that black box of a CPU is much much larger than it used to be. Right? Because they're doing -- in order to eke out all the performance and all the new things like that, you have to do extra-special tricks and things like that. And they have been, and sometimes those tricks come back to bite you in the butt. And they have, in this case. So we have to work around that.
But a companion article on Linux.com notes that "Intel has changed its approach in light of these events. 'They are reworking on how they approach security bugs and how they work with the community because they know they did it wrong,' Kroah-Hartman said." (And the article adds that "for those who want to build a career in kernel space, security is a good place to get started...")

Kroah-Hartman points out in the video interview that "we're doing more and more testing, more and more builds," noting "This infrastructure we have is catching things at an earlier stage -- because it's there -- which is awesome to see." But security issues can persist thanks to outside vendors beyond their control. Linux.com reports: Hardening the kernel is not enough, vendors have to enable the new features and take advantage of them. That's not happening. Kroah-Hartman releases a stable kernel every week, and companies pick one to support for a longer period so that device manufacturers can take advantage of it. However, Kroah-Hartman has observed that, aside from the Google Pixel, most Android phones don't include the additional hardening features, meaning all those phones are vulnerable. "People need to enable this stuff," he said.

"I went out and bought all the top of the line phones based on kernel 4.4 to see which one actually updated. I found only one company that updated their kernel," he said. "I'm working through the whole supply chain trying to solve that problem because it's a tough problem. There are many different groups involved -- the SoC manufacturers, the carriers, and so on. The point is that they have to push the kernel that we create out to people."
"The good news," according to Linux.com, "is that unlike with consumer electronics, the big vendors like Red Hat and SUSE keep the kernel updated even in the enterprise environment. Modern systems with containers, pods, and virtualization make this even easier. It's effortless to update and reboot with no downtime."

Bruce Perens co-founded the Open Source Initiative with Eric Raymond -- and he's also Slashdot reader #3872. But this week he wrote in with some news from the world of amateur (or "ham") radio: ARRL has been the USA's representative organization for Amateur Radio for over a century. More recently, the organization has replaced transparency and democratic representation of its membership with confidentiality, policies to stifle dissent, and punishment of their own leadership when they get out of line. A vote happening this month offers members a chance to get back in control.
The open letter at that link -- signed by several AARL life members (including Perens), argues that "The members are not currently represented as they should be, due to the continued application of a policy meant for a for-profit corporate board," adding that "The only whistle-blower on the board was publicly castigated for informing us."

"The currently-suspended rules that go against the member's interest are temporarily suspended, and could be restored."

AmiMoJo quotes Rock, Paper, Shotgun: Sandbox space sim Limit Theory has been cancelled, six years after a successful crowdfunding campaign on Kickstarter, because main developer Josh Parnell is simply exhausted from working on it for so long. He's spent, he says: emotionally, mentally, physically, and financially. "Not in my darkest nightmares did I expect this day to ever come, but circumstances have reached a point that even my endless optimism can no longer rectify," Parnell said on Friday. He plans to release the source code for folks to poke around but makes clear "it's not a working game."

Though Limit Theory blew past its $50,000 goal, drawing $187,865 in pledges (and remember Kickstarter takes a cut), development has gone on years longer than anticipated. Costs have burned through that initial cash and started eating into Parnell's personal savings but, more than that, he's just exhausted.

Long-time Slashdot reader RockDoctor writes: One of the key assumptions of Relativity — both Special and General — is that the speed of light is a constant in all non-accelerating reference frames. As a key assumption, it is also one of the things that gets the kooks, wingnuts and fanatics all riled up, because they have proven that it's wrong, though those pesky scientists refuse to listen to their spittle-flecked presentations.

Back in the real world, real scientists also wonder if the assumption is justified, then try to work out how to test it. One idea for performing this test has just been published — that of using the gravitational lensing of distant supernovae to try to interrogate the speed of light in the distant past.

When a (relatively) nearby galaxy lenses a (relatively) distant galaxy, it is common for multiple images to be formed. If a supernova occurs in the distant galaxy, then supernova images will be seen in the different images, but typically at different times (on Earth) because the light paths from different images are of different lengths, and were of different lengths in the past.

The Chinese-Polish team of authors have studied the possibilities of making such observations and suggest that the LSST (Large Synoptic Survey Telescope, "a wide-field survey reflecting telescope with an 8.4-meter primary mirror, currently under construction, that will photograph the entire available sky every few nights") should detect several thousand gravitationally-lensed distant quasars, and so yield around 50 gravitationally-lensed distant supernovas per year. This is estimated to "produce robust constraints on the speed of light at the level of delta-c/c;= 0.005" (half a percent) in a decade of operations.

Which will shut the wingnuts, lunatics and kooks up. Not.At.All.

OpenSourceAllTheWay writes: Elusive street artist Banksy's famous "Girl With Balloon" artwork was on sale at a Sotheby's auction in New York inside what looked like a normal, if slightly old fashioned painting frame. As soon as the auction concluded — the artwork was sold to a bidder for a cool $1.3 Million — a whirring noise started coming from the artwork hanging on the wall, and "Girl With Ballon" started moving down inside its frame, coming out the bottom of the frame in shredded strips. In what must be an art world first, the artwork suddenly self-shredded in front of hundreds of stunned auction attendants. It appears that — somehow — Banksy or some other prankster installed a battery powered paper shredding mechanism in the bottom of the artwork's frame that can be remotely triggered. In a tweet on his Twitter account, Banksy posted an image of the destructed artwork and wrote "Going, gone, gone...", potentially mocking the practice of auctioning famous artworks off for large sums of money. The question now is precisely what — if anything — the buyer of the artwork gets for his or her money, and whether "Girl With Balloon" is worth more or less than before now.

Amid reports of users facing a number of issues after updating their computers to Windows 10 October 2018 Update, Microsoft said Saturday it was pausing the rollout of the latest version of its Windows 10 desktop operating system. ZDNet: In a support document updated today, October 6, the Redmond-based OS maker said it took this decision after users complained that v1809 had deleted files after the update. We have paused the rollout of the Windows 10 October 2018 Update (version 1809) for all users as we investigate isolated reports of users missing some files after updating. Microsoft employs a gradual rollout scheme, and not all Windows 10 users have received its latest bi-annual OS update. The October 2018 Update is no longer available for download, and Microsoft urges users who manually downloaded a Windows 10 installation package to wait until new installation media is available. "We will provide an update when we resume rolling out the Windows 10 October 2018 Update to customers," Microsoft said.

An anonymous reader quotes a report from BuzzFeed News: Multiple senior Apple executives, speaking with BuzzFeed News on the condition of anonymity so that they could speak freely all denied and expressed confusion with a report earlier this week that the company's servers had been compromised by a Chinese intelligence operation. On Thursday morning, Bloomberg Businessweek published a bombshell investigation. The report -- the result of more than a year of reporting and over 100 interviews with intelligence and company sources -- alleged that Chinese spies compromised and infiltrated almost 30 U.S. companies including Apple and Amazon by embedding a tiny microchip inside company servers. Both Amazon and Apple issued uncharacteristically strong and detailed denials of Bloomberg's claims.

Reached by BuzzFeed News multiple Apple sources -- three of them very senior executives who work on the security and legal teams -- said that they are at a loss as to how to explain the allegations. These people described a massive, granular, and siloed investigation into not just the claims made in the story, but into unrelated incidents that might have inspired them. A senior security engineer directly involved in Apple's internal investigation described it as "endoscopic," noting they had never seen a chip like the one described in the story, let alone found one. "I don't know if something like this even exists," this person said, noting that Apple was not provided with a malicious chip or motherboard to examine. "We were given nothing. No hardware. No chips. No emails." Equally puzzling to Apple execs is the assertion that it was party to an FBI investigation -- Bloomberg wrote that Apple "reported the incident to the FBI." A senior Apple legal official told BuzzFeed News the company had not contacted the FBI, nor had it been contacted by the FBI, the CIA, the NSA or any government agency in regards to the incidents described in the Bloomberg report. This person's purview and responsibilities are of such a high level that it's unlikely they would not have been aware of government outreach.

NASA has switched its Curiosity rover over to its backup computer system after the main system started experiencing errors last month. "Many NASA spacecraft and surface missions have redundant systems built-in," reports ExtremeTech. "Once they've launched from Earth, there's no way to repair damage to critical systems, so it makes sense to double-up on the vital components. That includes Curiosity's computers, which were designed specifically for the harsh environment on Mars." From the report: The rover has a pair of identical brains running a 5-watt RAD750 CPU. This chip is part of the PowerPC 750 family, but it has been custom designed to survive high-radiation environments as you'd find on Mars or in deep space. These radiation-hardened CPUs cost $200,000 each, and NASA equipped the rover with two of them. Each computer also has 256 kB of EEPROM, 256 MB of DRAM, and 2 GB of flash memory. They run identical VxWorks real-time operating systems. When Curiosity landed on Mars in 2012, it used the "Side-A" computer. However, just a year later in 2013 (Sol 200), the computer failed due to corrupted memory. The rover got stuck in a bootloop, which prevented it from processing commands and drained the batteries. NASA executed a swap to Side-B so engineers could perform remote diagnostics on Side-A. In the following months, NASA confirmed that part of Side-A's memory was unusable and quarantined it. They kept Curiosity on Side-B, though. With Side-B experiencing problems preventing the rover from storing key science and engineering data, NASA switched Curiosity back to Side-A while it investigates the problem, which it can only do when the other computer is active. "NASA hasn't said how much of Side-A's RAM is bad, and it only had 256MB to start, but the team does intend to move Curiosity operations back to Side-B if possible," the report adds. "For now, the mission is functioning normally on Side-A."

An anonymous reader quotes a report from ScienceAlert: A new study argues that we have Neanderthals to thank for helping us cope with the viral tides we encountered as we marched around the globe. Stanford University researchers have identified DNA sequences that evolved in our ancient cousins can produce antivirus proteins, which more than likely gave some human populations the edge they needed to survive. Roughly 1 percent of our genome's coding was written in Neanderthal populations. But this is a broad average -- many families with African ancestry have zero, for instance, while other populations boast as much as 2 percent or more. So the question is how much of this difference comes down to the random drift of DNA being passed on around the globe, and how much is due to natural selection giving those with Neanderthal genes an advantage?

To build a case one way or another, the Stanford researchers put together a list of just over 4,500 virus-interacting proteins (VIP) made by our genome. These were all matched against a database of Neanderthal DNA that could be found in modern East Asian and European human populations, providing 152 VIP genes shared by both groups of human. Interestingly, all of these VIP genes were of a variety that interacted with RNA viruses -- pathogens that include influenza A, hepatitis C, and HIV. This isn't to say these viruses were problems for ancient humans, but rather that similar RNA viruses were more than likely prevalent enough to shape our evolution. The discovery supports a view of genetic exchange described as the 'poison-antidote' model.
