An anonymous reader quotes USA Today:
Might wearing an Apple Watch save you from a stroke or cardio problem? Apple is careful not to make that direct claim. But the company, in collaboration with Stanford University School of Medicine, launched the Apple Heart Study app on Thursday that uses the heart rate sensor inside the Apple Watch to collect data on irregular heart rhythms... If an irregular heart rhythm is detected, participants in the study will be notified through the Apple Watch and on their iPhones. Should that occur, you'll be offered a free consultation with a study doctor, and possibly an electrocardiogram patch for additional monitoring...
A participant in the study merely has to download the app and wear the watch... The way Apple explains it, a sensor inside the watch uses green LED lights flashing hundreds of times per second and light-sensitive photodiodes to detect the amount of blood flowing through the wrist. The sensor has an optical design that gathers signals from four distinct points on the wrist. Using software algorithms, the Apple Watch can isolate heart rhythms from other noise, and identify an irregular heart rhythm.
The FDA has also approved the first personal electrocardiogram accessory for the Apple Watch, according to TechNewsWorld. "The KardiaBand" also detects and records atrial fibrillation that can lead to strokes or other heart problems. "The user simply touches an integrated sensor, and the results are then displayed on the face of the Apple Watch."
An irregular, bloodflow-disrupting heartbeat is the top cause of strokes, which kill 130,000 people every year just in the U.S. -- in many case before they've experienced any symptoms.Read Replies (0)

Bitcoin "is drawing harsh criticism from Wall Street investment firms," writes Slashdot reader rmdingler -- and even from some prominent economists. CNN reports:
The harshest assessment came from Nobel laureate Joseph Stiglitz, who said that bitcoin "ought to be outlawed. Bitcoin is successful only because of its potential for circumvention," he told Bloomberg TV. "It doesn't serve any socially useful function." Robert Shiller, who won a Nobel for his work on bubbles, said the currency appeals to some investors because it has an "anti-government, anti-regulation feel. It's such a wonderful story," he said at a conference in Lithuania, according to Bloomberg. "If it were only true."
Wall Street titans were getting in on the action, too. Goldman Sachs CEO Lloyd Blankfein told Bloomberg that the currency serves as "a vehicle for perpetrating fraud." Billionaire investor Carl Icahn said on CNBC that it "seems like a bubble." The digital currency previously attracted the derision of JPMorgan boss Jamie Dimon, who called it a "fraud" that would "eventually blow up." Warren Buffett has warned of a "real bubble."
Wednesday the price of bitcoin shot past $11,000 -- just ten days after rising past $8,000.Read Replies (0)

InfoWorld published an interesting essay from Matt Asay, former COO at Canonical (and an emeritus board member of the Open Source Initiative), about innovation from the big public cloud vendors, which "even when open-sourced, doesn't really help the community at large... All this innovation is available to buy; none of it is available to build. Not for mere mortals, anyway."
Google in particular has figured out how to both open-source code in a useful way and make it pay. As Server Density CEO David Mytton has underlined, Google hopes to "standardize machine learning on a single framework and API," namely TensorFlow, then supplement it "with a service that can [manage] it all for you more efficiently and with less operational overhead," namely Google Cloud. By open-sourcing TensorFlow and backing it with machine-learning-heavy Google Cloud, Google has open-sourced a great on-ramp to future revenue.
My question: why not do this with the rest of its code? The simple answer is "Because it's a lot of work." That is, Google could open-source everything tomorrow without any damage to its revenue, but the code itself would provide other providers and enterprises only limited ability to increase their revenue unless Google did all the necessary prep work to make it useful to mere mortals not running superhuman Google infrastructure. This is the trick that AWS, Microsoft, and Google are all racing to figure out today. Not open source, per se, because that's the easy table stakes. No, the AWS/Microsoft Azure/Google Cloud trio are figuring out how to turn their innovations into open source on-ramps to their proprietary services. Companies used to lock up their code to sell it. Today, it's the opposite: They need to open it up to make their ability to operate the code at scale more valuable. For them.Read Replies (0)

14 terabytes of "highly confidential" data about 5,120 financial aid applications over seven years were exposed in a breach at Stanford's Graduate School of Business -- proving that the school "misled thousands of applicants and donors about the way it distributes fellowship aid and financial assistance to its MBA students," reports Poets&Quants.
The information was unearthed by a current MBA student, Adam Allcock, in February of this year from a shared network directory accessible to any student, faculty member or staffer of the business school. In the same month, on Feb. 23, the student reported the breach to Jack Edwards, director of financial aid, and the records were removed within an hour of his meeting with Edwards. Allcock, however, says he spent 1,500 hours analyzing the data and compiling an 88-page report on it...
Allcock's discovery that more money is being used by Stanford to entice the best students with financial backgrounds suggests an admissions strategy that helps the school achieve the highest starting compensation packages of any MBA program in the world. That is largely because prior work experience in finance is generally required to land jobs in the most lucrative finance fields in private equity, venture capital and hedge funds.
Half the school's students are awarded financial aid, and though Stanford always insisted it was awarded based only on need, the report concluded the school had been "lying to their faces" for more than a decade, also identifying evidece of "systemic biases against international students."

Despite the fact that 60% of its pizza orders arrive digitally, "A growing number of Domino's delivery customers are casting a critical eye at the company's online pizza-tracking app," reports the lifestyle editor at Fox News. "More specifically, they think it's a bunch of crap."
Fault-finding app users -- or "app truthers," as The Wall Street Journal calls them -- are subscribing to the notion that the Domino's pizza tracker is nothing but a bunch of smoke and mirrors. One user who spoke with the Journal claims his app told him that "Melinda" would be arriving shortly with his order, but when he opened the door, a delivery man he already knew handed him the pizza. "Ever since then, I knew everything they said, I felt, was made up," he said.
Another man claims the tracker told him his pizza was en route, even though he could see the Domino's restaurant from his house, and there was no sign of the pizza being out for delivery. Others claim the pizza app told them their food had been delivered when it hadn't, or that there were huge discrepancies between when their pies were supposed to be delivered and when they actually arrived. A whole thread on Reddit suggests that the app is just an automated timer disguised to look like a real-time tracker.
In a statement Domino's blamed the problem on employees not entering correct data, while also insisting that "the vast majority of the time Pizza Tracker works as designed."
According to the article, "A person who claimed to be a Domino's employee also said nearly as much in a 2015 Reddit thread. He/she added that the name of the person preparing the pizza -- as far as the app is concerned -- is usually the manager.Read Replies (0)

Slashdot reader Beeftopia shares "a detailed history of WebAssembly...from one of the developers." IEEE Spectrum reports that "Like a lot of stories about tech innovation, this one started with video games."
This brings us to the present... Emscripten can take code written in C++ and convert it directly into WebAssembly. And there will be ways in time to run other languages as well, including Rust, Lua, Python, Java, and C#. With WebAssembly, multimillion-line code bases can now load in a few seconds and then run at 80 percent of the speed of native programs. And both load time and execution speed are expected to improve as the browser engines that run the code are made better.

An anonymous reader quotes MarketWatch:
A group of global activists stormed and occupied several Apple Stores in France on Saturday in a move aimed at pressuring the company to pay up on a €13 billion ($15.5 billion) tax bill to the European Union. In a press release, the France unit of the Association for the Taxation of Financial Transactions and Citizen's Action organization (Attac), said 100 of its members occupied the Opera Apple Store in Paris, demanding the company pay its taxes... Attac said dozens of protests were organized at other Apple store locations throughout France on Saturday. In the Paris store, activists were seen via videos circulating on Twitter, pushing past security and hanging a banner that said "We will stop when Apple pays." Security in Paris reportedly evacuated Apple workers from the building as those protests began.
After three hours they left the store -- leaving behind protest messages on the iPads on display. The group claims that Apple has stashed $230 billion in tax havens around the world, but also hopes to raise awareness about other issues.
"Attac said the action was part of the #PhoneRevolt movement aimed at highlighting unfair practices by Apple, that are not just about taxes, but also pollution via extraction of metals for its phones, worker exploitation and driving a global consumption binge."Read Replies (0)

Staffers for Senate Republicans' campaign arm seized information on more than 200,000 donors from the House GOP campaign committee over several months this year by breaking into its computer system, three sources with knowledge of the breach told Politico... Multiple NRSC staffers, who previously worked for the NRCC, used old database login information to gain access to House Republicans' donor lists this year. The donor list that was breached is among the NRCC's most valuable assets, containing not only basic contact information like email addresses and phone numbers but personal information that could be used to entice donors to fork over cash -- information on top issues and key states of interest to different people, the names of family members, and summaries of past donation history... Donor lists like these are of such value to party committees that they can use them as collateral to obtain loans worth millions of dollars when they need cash just before major elections...
"The individuals on these lists are guaranteed money," said a Republican fundraiser. "They will give. These are not your regular D.C. PAC list"... The list has helped the NRCC raise over $77 million this year to defend the House in 2018... Though the House and Senate campaign arms share the similar goal of electing Republican candidates and often coordinate strategy in certain states, they operate on distinct tracks and compete for money from small and large donors.
Long-time Slashdot reader SethJohnson says the data breach "is the result of poor deprovisioning policies within the House Republican Campaign Committee -- allowing staff logins to persist after a person has left the organization."
NRCC officials who learned of the breach "are really pissed," one source told the site.Read Replies (0)

Bizzeh shared this report from the BBC:
A mother has written a letter in defense of her 14-year-old son who is facing a lawsuit over video game cheats in the US. Caleb Rogers is one of two people facing legal action from gaming studio Epic Games for using cheat software to play the free game Fortnite. The studio says it has taken the step because the boy declined to remove a YouTube video he published which promoted how to use the software... "This company is in the process of attempting to sue a 14-year-old child," she wrote in the letter which has been shared online by the news site Torrentfreak.
Ms. Rogers added that she had not given her son parental consent to play the game as stated in its terms and conditions, and that as the game was free to play the studio could not claim loss of profit as a result of the cheats... In a statement given to the website Kotaku, Epic Games said the lawsuit was a result of Mr. Rogers "filing a DMCA counterclaim to a takedown notice on a YouTube video that exposed and promoted Fortnite Battle Royale cheats and exploits... Epic is not OK with ongoing cheating or copyright infringement from anyone at any age," it said.
Cory Doctorow counters that the 14-year-old "correctly asserted that there was no copyright infringement here. Videos that capture small snippets of a videogame do not violate that game creator's copyrights, because they are fair use..."Read Replies (0)

Bruce Perens co-founded the Open Source Initiative with Eric Raymond -- and he's also Slashdot reader #3872. Bruce Perens writes: Red Hat, IBM, Google, and Facebook announced that they would give infringers of their GPL software up to a 30-day hold-off period during which an accused infringer could cure a GPL violation after one was brought to their attention by the copyright holder, and a 60 day "statute of limitations" on an already-cured infringement when the copyright holder has never notified the infringer of the violation. In both cases, there would be no penalty: no damages, no fees, probably no lawsuit; for the infringer who promptly cures their infringement.
Perens sees the move as "obviously inspired" by the kernel team's earlier announcement, and believes it's directed against one man who made 50 copyright infringement claims involving the Linux kernel "with intent to collect income rather than simply obtain compliance with the GPL license."
Unfortunately, "as far as I can tell, it's Patrick McHardy's legal right to bring such claims regarding the copyrights which he owns, even if it doesn't fit Community Principles which nobody is actually compelled to follow."Read Replies (0)

An anonymous reader quotes Ars Technica's report on Russia's failed attempt to launch 19 satellites into orbit on Tuesday:
Instead of boosting its payload, the Soyuz 2.1b rocket's Fregat upper stage fired in the wrong direction, sending the satellites on a suborbital trajectory instead, burning them up in Earth's atmosphere... According to normally reliable Russian Space Web, a programming error caused the Fregat upper stage, which is the spacecraft on top of the rocket that deploys satellites, to be unable to orient itself. Specifically, the site reports, the Fregat's flight control system did not have the correct settings for a mission launching from the country's new Vostochny cosmodrome. It evidently was still programmed for Baikonur, or one of Russia's other spaceports capable of launching the workhorse Soyuz vehicle. Essentially, then, after the Fregat vehicle separated from the Soyuz rocket, it was unable to find its correct orientation. Therefore, when the Fregat first fired its engines to boost the satellites into orbit, it was still trying to correct this orientation -- and was in fact aimed downward toward Earth.
Though the Fregat space tug has been in operation since the 1990s, this is its fourth failure -- all of which have happened within the last 8 years.
"In each of the cases, the satellite did not reach its desired orbit," reports Ars Technica, adding "As the country's heritage rockets and upper stages continue to age, the concern is that the failure rate will increase."Read Replies (0)

Mozilla's VP of Technology Strategy, Sean White, writes:
I'm excited to announce the initial release of Mozilla's open source speech recognition model that has an accuracy approaching what humans can perceive when listening to the same recordings... There are only a few commercial quality speech recognition services available, dominated by a small number of large companies. This reduces user choice and available features for startups, researchers or even larger companies that want to speech-enable their products and services. This is why we started DeepSpeech as an open source project. Together with a community of likeminded developers, companies and researchers, we have applied sophisticated machine learning techniques and a variety of innovations to build a speech-to-text engine that has a word error rate of just 6.5% on LibriSpeech's test-clean dataset. vIn our initial release today, we have included pre-built packages for Python, NodeJS and a command-line binary that developers can use right away to experiment with speech recognition.
The announcement also touts the release of nearly 400,000 recordings -- downloadable by anyone -- as the first offering from Project Common Voice, "the world's second largest publicly available voice dataset." It launched in July "to make it easy for people to donate their voices to a publicly available database, and in doing so build a voice dataset that everyone can use to train new voice-enabled applications." And while they've started with English-language recordings, "we are working hard to ensure that Common Voice will support voice donations in multiple languages beginning in the first half of 2018."

"A man with an anti-media agenda was arrested in Oakland after he flew a drone over two different stadiums to drop leaflets" last Sunday, writes Slashdot reader execthis. A local CBS station reports:
According to investigators, [55-year-old Tracy] Mapes piloted his drone over Levi's Stadium during the second quarter of the 49ers-Seattle game and released a load of pamphlets. He then quickly landed the drone, loaded it up and drove over to Oakland. He flew a similar mission over the Raiders-Broncos game. Santa Clara Police Lt. Dan Moreno said after Mapes was apprehended he defended the illegal action as a form of free speech.
USA Today reports there's now also an ongoing federal investigation "because the Federal Aviation Administration prohibits the flying of drones within five miles of an airport. Both Levi's Stadium and Oakland Coliseum are within that range."

An anonymous reader quotes Ars Technica:
Previously, SpaceX founder Elon Musk has said he intends to launch the "silliest thing we can imagine" on the maiden launch of the Falcon Heavy. This is partly because the rocket is experimental -- there is a non-trivial chance the rocket will explode on the launch pad, or shortly after launch. It is also partly because Musk is a master showman who knows how to grab attention. On Friday evening, Musk tweeted what that payload would be -- his "midnight cherry Tesla Roadster."
And the car will be playing Space Oddity, by David Bowie; the song which begins, "Ground Control to Major Tom." Oh, and the powerful Falcon Heavy rocket will send the Tesla into orbit around Mars. "Will be in deep space for a billion years or so if it doesn't blow up on ascent," Musk added. Ars was able to confirm Friday night from a company source that this is definitely a legitimate payload. Earlier on Friday, Musk also said the Falcon Heavy launch would come "next month" from Launch Pad 39A at Kennedy Space Center in Florida, meaning in January.
"No private company has ever launched a spacecraft beyond low-Earth orbit, let alone to another planet," according to the article, adding that SpaceX's new rocket "could play a major role in any plans the agency has to send humans to the Moon."

An anonymous reader quotes a report from The Guardian: Electric cars are already cheaper to own and run than petrol or diesel cars in the UK, US and Japan, new research shows. The lower cost is a key factor driving the rapid rise in electric car sales now underway, say the researchers. At the moment the cost is partly because of government support, but electric cars are expected to become the cheapest option without subsidies in a few years. The researchers analyzed the total cost of ownership of cars over four years, including the purchase price and depreciation, fuel, insurance, taxation and maintenance. They were surprised to find that pure electric cars came out cheapest in all the markets they examined: UK, Japan, Texas and California.
Pure electric cars have much lower fuel costs -- electricity is cheaper than petrol or diesel -- and maintenance costs, as the engines are simpler and help brake the car, saving on brake pads. In the UK, the annual cost was about 10% lower than for petrol or diesel cars in 2015, the latest year analyzed. Hybrid cars which cannot be plugged in and attract lower subsidies, were usually a little more expensive than petrol or diesel cars. Plug-in hybrids were found to be significantly more expensive -- buyers are effectively paying for two engines in one car, the researchers said. The exception in this case was Japan, where plug-in hybrids receive higher subsidies. The study has been published in the journal Applied Energy.Read Replies (0)

General Motors has laid out a plan to not only mass-deploy self-driving cars on public roads in 2019, but to do it profitably. "With a driverless ride-hailing service as its framework, GM is counting on cost reductions, advancements in autonomous technologies and growth of the ride-hailing market to enable a successful self-driving car launch in 2019," reports The Detroit News. From the report: The automaker is using the all-electric Chevrolet Bolt as its autonomous mule, dovetailing Thursday's autonomous projection with GM's earlier vow to roll out a profitable electric vehicle platform by 2021. "For GM to get the benefit they're looking for, they need these cars on the road at scale as soon as possible," said Navigant Research analyst Sam Abuelsamid. "With ride-hailing services, consumers are saved from sticker shock of how much an EV costs -- and the cost of automation in early years is going to be expensive, too." GM didn't say exactly where it plans to launch its driverless ride-hailing service, but identified "dense urban environments" in the presentation. The Detroit automaker's testbeds for the self-driving Bolt are in Warren, San Francisco and Scottsdale, Arizona.Read Replies (0)

hackingbear shares a report from Science Magazine: Results reported by a China-led space science mission provide a tantalizing hint -- but not firm evidence -- for dark matter. In its first 530 days of scientific observations, China's Dark Matter Particle Explorer (DAMPE) detected 1.5 million cosmic ray electrons and positrons above a certain energy threshold. When researchers plot of the number of particles against their energy, they saw hints of an anomalous break in the curve. Now, DAMPE has confirmed that deviation. "It may be evidence of dark matter," but the break in the curve "may be from some other cosmic ray source," says astrophysicist Chang Jin, who leads the collaboration at the Chinese Academy of Science's Purple Mountain Observatory in Nanjing. DAMPE's life span will be extended to 5 years given the excellent conditions of this Chinese spacecraft, then it can record over 10 billion cosmic events, allowing researchers to confirm if it is indeed dark matter. Perhaps more significantly, the first observational data produced by China's first mission dedicated to astrophysics shows that the country is set to become a force in space science, says David Spergel, an astrophysicist at Princeton University. China is now "making significant contributions to astrophysics and space science," he says. The DAMPE results appear online in the journal Nature.Read Replies (0)

An anonymous reader quotes a report from Inverse: In the new paper, presented Thursday at the annual meeting of the Radiological Society of North America, a team of radiologists at Korea University report that smartphone addiction changes teenagers' brains. Using brain imaging, they argue that smartphone- and internet-addicted teenagers have imbalanced brain chemistry when compared to their peers who aren't addicted to smartphones or the internet. But scientists not involved with the study have some serious issues with their research. Perhaps the most important of these issues is the fact that "smartphone addiction" is not a scientifically established thing -- at least not yet.
In the study, the team led by Dr. Hyung Suk Seo used "standardized internet and smartphone addiction tests to measure the severity of internet addiction" in nine boys and 10 girls, according to a statement. Then, they used MRS, a brain imaging technique that can identify particular brain chemicals, to examine the participants' brains before and after taking nine weeks of cognitive behavioral therapy to help their "addiction." Compared to a control group, the "smartphone addicts" had skewed levels of neurotransmitters in their brains. In particular, they had a higher ratio of GABA to Glx (glutamateglutamine), which are respectively responsible for slowing down brain signals and exciting neurons. An elevated ratio of GABA to Glx, the researchers concluded, can be associated with the self-reported symptoms of the "smartphone addict" teens, including depression, anxiety, insomnia severity and impulsivity. After 12 of the teens participated in cognitive behavior therapy, the scientists report, their chemical imbalances appeared to even out to look more like the control group's.Read Replies (0)
