The Apple Watch Heart Monitor Sends Too Many People To the Doctor

Slashdot - Sat, 2020-10-03 00:02
The heart monitoring feature on the Apple Watch may lead to unnecessary health care visits, according to a new study published this week. The Verge reports: Only around 10 percent of people who saw a doctor at the Mayo Clinic after noticing an abnormal pulse reading on their watch were eventually diagnosed with a cardiac condition. The finding shows that at-home health monitoring devices can lead to over-utilization of the health care system, said study author Heather Heaton, an assistant professor of emergency medicine at the Mayo Clinic College of Medicine, in an email to The Verge. That may be expensive for patients and for the system as a whole, and it may take up doctor and patient time unnecessarily. Heaton and the study team scanned patient health records at every Mayo Clinic site, including offices in Arizona, Florida, Wisconsin, and Iowa, for mentions of the term "Apple Watch" over a six-month period from December 2018 to April 2019. The window came just after Apple introduced a feature to detect abnormal heart rhythms and after publication of a study tracking how well the watches could detect atrial fibrillation. They found records of 264 patients who said their Apple Watches flagged a concerning heart rhythm. Of that group, 41 explicitly mentioned getting an alert from their watch (others may have had an alert, but it wasn't mentioned specifically in their health record). Half of the patients already had a cardiac diagnosis, including 58 who'd been previously diagnosed with atrial fibrillation. About two-thirds had symptoms, including lightheadedness or chest pain. Only 30 patients in the study got a cardiac diagnosis after their doctors visit. Most of the concerning heart monitor data, then, were probably false positives, the study concluded.

Trump Goes To Hospital After Testing Positive For COVID-19

Slashdot - Fri, 2020-10-02 23:23
President Donald Trump has been flown to the hospital less than 24 hours after testing positive for COVID-19. The BBC reports: The White House said the decision to transport him to Walter Reed National Military Medical Center was taken "out of an abundance of caution." Mr Trump began exhibiting "mild symptoms" of Covid-19 on Thursday. He said early on Friday he and First Lady Melania Trump had tested positive. The White House said he was feeling "fatigued but in good spirits." Wearing a mask and suit, Mr Trump walked out across the White House lawn on Friday afternoon to his helicopter, Marine One, for the short trip to hospital. He waved and gave a thumbs-up to reporters but said nothing before boarding the aircraft. In a video posted to Twitter, Mr Trump said: "I want to thank everybody for the tremendous support. I'm going to Walter Reed hospital. I think I'm doing very well. But we're going to make sure that things work out. The first lady is doing very well. So thank you very much, I appreciate it, I will never forget it -- thank you."

A Security Flaw In Grindr Let Anyone Easily Hijack User Accounts

Slashdot - Fri, 2020-10-02 22:50
Grindr, one of the world's largest dating and social networking apps for gay, bi, trans, and queer people, has fixed a security vulnerability that allowed anyone to hijack and take control of any user's account using only their email address. TechCrunch reports: Wassime Bouimadaghene, a French security researcher, found the vulnerability and reported the issue to Grindr. When he didn't hear back, Bouimadaghene shared details of the vulnerability with security expert Troy Hunt to help. The vulnerability was fixed a short time later. Bouimadaghene found the vulnerability in how the app handles account password resets. To reset a password, Grindr sends the user an email with a clickable link containing an account password reset token. Once clicked, the user can change their password and is allowed back into their account. But Bouimadaghene found that Grindr's password reset page was leaking password reset tokens to the browser. That meant anyone could trigger the password reset who had knowledge of a user's registered email address, and collect the password reset token from the browser if they knew where to look. The clickable link that Grindr generates for a password reset is formatted the same way, meaning a malicious user could easily craft their own clickable password reset link -- the same link that was sent to the user's inbox -- using the leaked password reset token from the browser. With that crafted link, the malicious user can reset the account owner's password and gain access to their account and the personal data stored within, including account photos, messages, sexual orientation and HIV status and last test date.

How One Piece of Hardware Took Down a $6 Trillion Stock Market

Slashdot - Fri, 2020-10-02 22:10
An anonymous reader quotes a report from Bloomberg on how a data storage and distribution device brought down Tokyo's $6 trillion stock market: At 7:04 a.m. on an autumn Thursday in Tokyo, the stewards of the world's third-largest equity market realized they had a problem. A data device critical to the Tokyo Stock Exchange's trading system had malfunctioned, and the automatic backup had failed to kick in. It was less than an hour before the system, called Arrowhead, was due to start processing orders in the $6 trillion equity market. Exchange officials could see no solution. The full-day shutdown that ensued was the longest since the exchange switched to a fully electronic trading system in 1999. It drew criticism from market participants and authorities and shone a spotlight on a lesser-discussed vulnerability in the world's financial plumbing -- not software or security risks but the danger when one of hundreds of pieces of hardware that make up a trading system decides to give up the ghost. The TSE's Arrowhead system launched to much fanfare in 2010, billed as a modern-day solution after a series of outages on an older system embarrassed the exchange in the 2000s. The "arrow" symbolizes speed of order processing, while the "head" suggests robustness and reliability, according to the exchange. The system of roughly 350 servers that process buy and sell orders had had a few hiccups but no major outages in its first decade. That all changed on Thursday, when a piece of hardware called the No. 1 shared disk device, one of two square-shaped data-storage boxes, detected a memory error. These devices store management data used across the servers, and distribute information such as commands and ID and password combinations for terminals that monitor trades. When the error happened, the system should have carried out what's called a failover -- an automatic switching to the No. 2 device. But for reasons the exchange's executives couldn't explain, that process also failed. That had a knock-on effect on servers called information distribution gateways that are meant to send market information to traders. At 8 a.m., traders preparing at their desks for the market open an hour later should have been seeing indicative prices on their terminals as orders were processed. But many saw nothing, while others reported seeing data appearing and disappearing. They had no idea if the information was accurate. At 8:36 a.m., the bourse finally informed securities firms that trading would be halted. Three minutes later, it issued a press release on its public website -- although only in Japanese. A confusingly translated English release wouldn't follow for more than 90 minutes. It was the first time in almost fifteen years that the exchange had suffered a complete trading outage. The Tokyo bourse has a policy of not shutting even during natural disasters, so for many on trading floors in the capital, this experience was a first. After trading was called off for the day, four TSE executives held a press conference, "discussing areas such as systems architecture in highly technical terms," reports Bloomberg. "They also squarely accepted responsibility for the incident, rather than trying to deflect blame onto the system vendor Fujitsu Ltd." One of the biggest questions that remained unanswered is whether the same kind of hardware-driven failure could happen in other stock markets. "There's nothing uniquely Japanese about this," said Nicholas Smith of CLSA Ltd. in Tokyo. "I think we've just got to put that in the box of 'stuff happens.' These things happen. They shouldn't, but they do."

New James Bond Film 'No Time to Die' Is Delayed Until 2021

Slashdot - Fri, 2020-10-02 20:50
The next big Hollywood movie release, Metro-Goldwyn-Mayer's James Bond flick "No Time to Die," is being delayed again, Bloomberg reported Friday, citing a person with knowledge of the situation, a result of the woeful economics that studios are facing because of the pandemic. From a report: "No Time to Die" will be released in 2021, said the person, who asked not to be identified because the decision isn't yet public. It had already been delayed from April to Nov. 20, after the pandemic forced movie theaters across the world to close. Hollywood has a growing inventory of big movies sitting on the shelf because of Covid-19. The only major film that's been released since the pandemic started, Warner Bros.'s "Tenet," has attracted a small domestic audience -- partly because theaters in New York and Los Angeles are closed. Cinemas also have to cap ticket sales to adhere to social-distancing requirements. The Bond film, which cost about $250 million to make, will now compete with other big movies for audience attention in 2021. The change also means theaters will have no major movies for adults to show until the end of the year, when Warner Bros. is scheduled to release sci-fi thriller "Dune" and DC Comics installment "Wonder Woman 1984."

Facebook Rebuts Netflix Documentary 'The Social Dilemma'

Slashdot - Fri, 2020-10-02 20:10
Facebook on Friday offered a rebuttal to the hit Netflix documentary-drama, "The Social Dilemma." The movie revealed, perhaps for the first time to some viewers, how social networks use algorithms to keep people coming back. It also addressed how tech companies have influenced elections, ethnic violence and rates of depression and suicide. Some viewers said they were deleting Facebook and Instagram after watching it. From a report: The rebuttal suggests that Facebook may be worried that the documentary's effects on usage. "The Social Dilemma" appeared in Netflix's top ten most popular movies and TV shows list in September and is still listed in its Trending section. In a post published on its site, Facebook addressed several concerns it has with the movie, covering topics like addiction, users being "the product," its algorithms, data privacy, polarization, elections and misinformation. "Rather than offer a nuanced look at technology, it gives a distorted view of how social media platforms work to create a convenient scapegoat for what are difficult and complex societal problems," Facebook said. It said the documentary sensationalizes social networks and provides a distorted view to how they work.

Huawei's Investments Are 'Predatory Actions' and All Countries Should Ban Them: Pompeo

Slashdot - Fri, 2020-10-02 19:30
Investments by China's Huawei are not regular market transactions but rather "predatory actions" and all countries should ban them, U.S. Secretary of State Mike Pompeo said in a newspaper interview on Friday. From a report: "Their investments are not private because they are subsidised by the (Chinese) State. Hence they are not transparent, free, commercial transactions like many others but they are rather carried out to the exclusive benefit of (China's) security apparatus," Pompeo told Italian daily la Repubblica, at the end of his two-day visit to the country. "(Huawei's investments) are predatory actions that no nation must or can allow," he added.

Google Contractors Allege Company Prevents Them From Whistleblowing, Writing Silicon Valley Novels

Slashdot - Fri, 2020-10-02 18:55
Google contract employees are alleging the company's confidentiality agreements prevent them from a range of legal rights from whistleblowing to telling their parents how much they make, according to a recent court filing. From a report: A California appeals court recently discussed a lawsuit accusing Google and one of its staffing firms, Adecco, of violating a number of California labor laws, including free speech, by requiring workers to sign extensive confidentiality agreements. The contractors state they can't talk about their wages, working conditions or colleagues, among other things, according to the court filing. "As a practical matter, plaintiffs argue, they are forbidden even to write a novel about working in Silicon Valley or to reassure their parents they are making enough money to pay their bills, matters untethered to any legitimate need for confidentiality," the filing states.

How the Brain Handles the Unknown

Slashdot - Fri, 2020-10-02 18:08
Uncertainty can be hard for humans. It drives anxiety, an emotion neuroscientists are trying to understand and psychologists are trying to better treat. From a report: Under the threat of a virus, job insecurity, election uncertainty, and a general pandemic life-in-limbo that is upending school, holidays and more, people are especially anxious. Before the pandemic, anxiety was already climbing in the U.S., especially among young adults, according to a recent study. Add the pandemic and its many unknowns: 35% of adults in the Household Pulse Survey reported symptoms of anxiety disorder in July. (In the first half of 2019, it was roughly 8%.) "We have anxiety for a reason," says Stephanie Gorka, who studies the neurobiology of anxiety and treatments for anxiety-related disorders and phobias at the Ohio State University. Anxiety alerts people to pay attention to their environment and is key to our survival, but if it is chronic or excessive, it can have negative health consequences, she says. But how exactly the brain responds to uncertainty and leads to anxiety is unclear.

Pixel Miss

Slashdot - Fri, 2020-10-02 17:34
Ben Wood and Geoff Blaber, commenting on Google's new Pixel smartphones at research firm CCI Insight: Historically, Google has been one of the leaders in developing and implementing computational photography, mixing optics with digital sleight of hand to make imaging magic. And again, Google is promising great photography by using software smarts. The camera on the new phones has an ultrawide lens, a Night Sight feature that works in portrait mode, and a setting that lets users adjust the lighting in post-processing. The challenge for Google is that its camera capabilities are no longer unique, as all leading smartphone makers focus on camera and imaging tech to try and make their latest and greatest devices stand out. [....] Given Google's scale, the progress of the Pixel business has been disappointing, particularly in light of the difficulties Huawei has faced. Mobile operators, retailers and consumers would benefit from a credible alternative to Apple and Samsung. On paper Google should fit the bill, but the company has consistently failed to live up to expectations. Sadly, it's hard to see how these new devices will do anything to address these shortcomings. Google's smartphone hardware strategy is in need of a reset. The company either needs to deliver differentiated flagship Android experiences or mass-market products with broad distribution. Right now, it provides neither and sits awkwardly within a vibrant ecosystem of Android players led by Samsung. Google must prove that Pixel still has a role.

Facebook Sues Two Chrome Extension Makers For Scraping User Data

Slashdot - Fri, 2020-10-02 16:45
Facebook has filed a lawsuit against two companies for creating and distributing malicious browser extensions that scraped user data without authorization from the Facebook and Instagram websites. From a report: Named in the lawsuit are BrandTotal, an Israeli-based company with a Delaware subsidiary, and Unimania, incorporated in Delaware. The two companies are behind UpVoice and Ads Feed, two Chrome extensions available on the official Chrome Web Store since September and November 2019, where they racked up more than 5,000 and 10,000 installs, respectively. "BrandTotal enticed users to install the UpVoice extension from the Google Chrome Store by offering payments in exchange for installs, in the form of online gift cards, and claiming that the users who installed the extension became 'panelists . . . [who] impact the marketing decisions and brand strategies of multi-billion dollars (sic) corporations'," Facebook said in court documents filed today.

Twitter Wants To Tackle Its Biased Image Cropping Problem By Giving Users More Control

Slashdot - Fri, 2020-10-02 16:06
An anonymous reader shares a report: Last month, a bunch of users tweeted about how Twitter's image cropping algorithm seems to have a bias towards fair-skinned people. When users posted uncropped images containing both light and dark-skinned people, the social network's algorithm often showed the light-skinned person in the preview. At that time, Twitter said, while its algorithm was tested for bias, it will conduct further investigations to resolve the issue. Last night, in an update, the company said it's planning to give users more control over how the final image will look like.
