A new study published in the journal Emotion has found that playing the classic game of Tetris can help sooth the mind when you are awaiting uncertain news. The Week reports: The venerable video game was used in a recent experiment to create a state of flow -- the term psychologists use to describe a state of mind so engaged it makes the rest of the world fall away, and time pass more quickly. Researchers from University of California (UC) Riverside in the U.S. have found that state of perfect disengagement may improve the otherwise-emotionally unpleasant experience of waiting for uncertain news. In place of Tetris, in which blocks are flipped every which way and stacked into rows, one can substitute flow activities such as rock climbing, carpentry, playing chess, or swimming, researchers said.
For the research published in the journal Emotion, 290 undergraduate students were told the study would be about physical attractiveness. They filled out a questionnaire, after which a photo was taken of them. They were then told that students in another location would rate their physical attractiveness. While they were ostensibly being rated, the students were then asked to play Tetris for 10 minutes. [...] The participants who achieved flow -- those in the adaptive group -- experienced less negative emotion, and greater positive emotion than those who were bored, or for whom the level of play was too difficult.

Yesterday, during the company's Q4 earnings call, Apple's chief financial officer Luca Maestri said the company will no longer report unit sales of its main hardware divisions, including iPhones, iPad, and Mac. "This is the same as protocols Apple already follows for its smaller devices, such as the Apple Watch, AirPods, and HomePod, which are bundled under the 'Other Products' category," The Verge reports. From the report: The announcement comes after iPhone unit sales percentage was unchanged year over year, despite a revenue bump of 29 percent. The decision to stop disclosing unit sales is because that figure is "not representative of underlying strength of our business," Maestri said. "A unit of sale is less relevant today than it was in our past," he says, adding that unit sales increase are still a clear part of Apple's goals. While unit sales may not accurately represent Apple's business performance, it's a figure that analysts and journalists have used to calculate a product's average selling price. For example, that number can provide insight into how well different iPhone models are selling, as newer iPhones like the XS, XS Max, and XR are priced higher than older models like the now-discontinued SE, 6S, and 6.

Tesla said in a regulatory filing Friday that the SEC and Justice Department are investigating their Model 3 production projections to see if they misled investors. CNBC reports: The filing confirms much of an Oct. 26 article in The Wall Street Journal that said FBI agents were looking at whether Tesla misled investors about production of its Model 3 sedans. The FBI is the principal investigative arm of the Justice Department. The SEC, which just settled its securities fraud investigation against CEO Elon Musk and the company, has separately subpoenaed Tesla for Musk's statements about production rates regarding its popular Model 3 sedan, the company said. DOJ prosecutors have also asked for the same information, although it stopped short of issuing a formal subpoena, the company said in a filing with the SEC. In an interview with Recode's Kara Swisher, Elon Musk denied the validity of the WSJ article. "The amount of untruthful stuff that is written is unbelievable. Take that Wall Street Journal front-page article about, like, 'The FBI is closing in.' That is utterly false. That's absurd," Musk told Swisher. "To print such a falsehood on the front page of a major newspaper is outrageous. Like, why are they even journalists? They're terrible. Terrible people."

An anonymous reader quotes a report from Science Magazine: In the first attempt of its kind, researchers plan to sequence all known species of eukaryotic life -- 66,000 species of animals, plants, fungi, and protozoa -- in a single country, the United Kingdom. The announcement was made here today at the official launch of an even grander $4.7 billion global effort, called the Earth BioGenome Project (EBP), to sequence the genomes of all of Earth's known 1.5 million species of eukaryotes within a decade. The U.K. sequencing effort -- dubbed The Darwin Tree of Life project -- will now become part of the EBP mix. The Wellcome Sanger Institute in Hinxton, U.K., says it plans to sequence all known 66,000 species of eukaryotes found within the United Kingdom, except for its overseas territories. Collaborators will include the European Molecular Biology Laboratory in Hinxton, the Royal Botanic Gardens, Kew in the United Kingdom, and the Natural History Museum in London. Sanger will spend up to 50 million British pounds over 8 years, about 4% of its annual budget, on the first phase of the project, which will focus on developing the processes for sample collection, R&D on sequencing, and computational methods for assembling the genomes. Sanger director Mike Stratton said he expects another 100 million British pounds will be needed over the next 5 to 7 years for the bulk of sample collections and sequencing.

Iwastheone shares a report from Ars Technica: Mario Segale, the Seattle real estate and construction business owner who inspired the name for Nintendo's famous mascot, passed away on October 27 according to reports from The Seattle Times and The Auburn Reporter. He was 84 years old. Segale owned the business park housing Nintendo's American arcade operation in the early '80s, when the company was busy converting thousands of disused Radarscope cabinets to play Donkey Kong. At the time, Nintendo of America President Minoru Arakawa and other executives were trying to come up with an Americanized name for the game's player avatar, who was still referred to as "Jumpman" at that point (a name that appears on early Donkey Kong cabinet art). As the story goes, when Segale came to Arakawa to demand payment for a late rent bill, inspiration struck. While the broad strokes of Segale's role in Mario's naming remain consistent, the particulars can change with the retelling. David Sheff's seminal Nintendo history Game Over suggests the executives exclaimed "Super Mario!" after Segale's visit in 1981 (though the book misspells his name "Segali"). As Benj Edwards notes in an in-depth 2010 exploration of the tale, though, the "Super" descriptor for the character wouldn't become common until the release of Super Mario Bros. in 1985. Other retellings over the years go so far as to suggest that the "Super" came from Segale's role as "superintendent" of the building, but these stories offer little in the way of direct evidence. Ars mentions a 1993 Seattle Times article that quotes Segale as joking, "You might say I'm still waiting for my royalty checks."

chiefcrash shares a report from The New York Times about a man who wants to build a community based on the blockchain technology introduced by Bitcoin: An enormous plot of land in the Nevada desert -- bigger than nearby Reno -- has been the subject of local intrigue since a company with no history, Blockchains L.L.C., bought it for $170 million in cash this year. The man who owns the company, a lawyer and cryptocurrency millionaire named Jeffrey Berns, put on a helmet and climbed into a Polaris off-road vehicle last week to give a tour of the sprawling property and dispel a bit of the mystery. He imagines a sort of experimental community spread over about a hundred square miles, where houses, schools, commercial districts and production studios will be built. The centerpiece of this giant project will be the blockchain, a new kind of database that was introduced by Bitcoin. So far, he said, he has spent $300 million on the land, offices, planning and a staff of 70 people. And buying 67,000 largely undeveloped acres is a bit of old-fashioned, real estate risk-taking. Still, Mr. Berns said his ambition was not to be a real estate magnate or even to get rich -- or richer. He is promising to give away all decision-making power for the project and 90 percent of any dividends it generates to a corporate structure that will be held by residents, employees and future investors. That structure, which he calls a "distributed collaborative entity," is supposed to operate on a blockchain where everyone's ownership rights and voting powers will be recorded in a digital wallet. "In a keynote spectacle at Devcon4 in Prague, Berns announced some of their plans for the future, as well as some of their recent activities, such as buying two nuclear bomb shelters, a mountain fortress in Switzerland, and a bank," adds Slashdot reader chiefcrash.

An app you may have never heard about is growing at an impressive rate. From a report: Beijing-based ByteDance's 2017 acquisition of tween and teen-focused social app Musical.ly is paying off. The company this year merged Musical.ly with its own short video app TikTok as a means of entering the U.S. market. Today, the result of that merger is sitting at the top of the U.S. App Store, ahead of Facebook. More importantly, it recently surpassed Facebook, Instagram, YouTube and Snapchat in monthly installs for the first time in September. According to data from app intelligence firm Sensor Tower, TikTok's installs were higher than those of Facebook, Instagram, Snapchat and YouTube in the U.S. last month. It surpassed the four other apps in terms of daily downloads on September 29, with 29.7 percent the downloads from this cohort of apps, the firm says.

Making Trains Run on Time

Plamen Angelov of the University of Lancaster, in Britain, has an idea that he hopes will make train delays rarer. From a report: Often, Dr Angelov observes, the problem is not the inefficiency of operators but the behaviour of passengers -- the "platform-train interface", to use railway parlance. When trains arrive, passengers crowd around the doors waiting to board, restricting the flow of those getting off. When they are about to depart, people often hold doors open, delaying that departure. (A recent study by Japan's Railway Bureau found that passengers attempting to board trains after their scheduled departure times accounted for almost 50% of delays.) Passengers also frequently stand too close to the carriages for safety. Waiting for malefactors to move back behind the yellow safety line on a platform might hold a train up for less than a minute. But over the course of a journey those minutes add up. Even a slight delay is compounded if it causes a train to slip out of its running order and be held at a subsequent station, or be required to follow a slower service. Dr Angelov thinks that applying artificial intelligence to the problem might help. And that is what he and his team are doing. Using images from the cctv cameras already mounted in carriages and on platforms, their system employs algorithms that have been trained to detect objects such as people, luggage, pushchairs and bicycles. It then measures the movements and positions of these objects relative to areas such as the train doors or the yellow safety line and uses this information to predict problems. The cameras in the carriages detect how busy particular doors are getting as passengers leave their seats and gather next to the exits when the train approaches a station. At the same time, the station cameras monitor the numbers waiting for the train to arrive, whereabouts they are standing along the platform, and how encumbered they are. The two sets of data can then be compared, providing warning of likely areas of congestion. This permits passengers -- particularly those on the platform -- to be directed to doors that will be less busy.

Multiple readers have shared a report: Apparently fueled by anti-Semitism and the bogus narrative that outside forces are scheming to exterminate the white race, Robert Bowers murdered 11 Jewish congregants as they gathered inside their Pittsburgh synagogue, federal prosecutors allege. But despite long-running international efforts to debunk the idea of a "white genocide," Facebook was still selling advertisers the ability to market to those with an interest in that myth just days after the bloodshed. Earlier this week, The Intercept was able to select "white genocide conspiracy theory" as a pre-defined "detailed targeting" criterion on the social network to promote two articles to an interest group that Facebook pegged at 168,000 users large and defined as "people who have expressed an interest or like pages related to White genocide conspiracy theory." The paid promotion was approved by Facebook's advertising wing. After we contacted the company for comment, Facebook promptly deleted the targeting category, apologized, and said it should have never existed in the first place. Our reporting technique was the same as one used by the investigative news outlet ProPublica to report, just over one year ago, that in addition to soccer dads and Arianna Grande fans, "the world's largest social network enabled advertisers to direct their pitches to the news feeds of almost 2,300 people who expressed interest in the topics of 'Jew hater,' 'How to burn jews,' or, 'History of "why jews ruin the world."" The report exposed how little Facebook was doing to vet marketers, who pay the company to leverage personal information and inclinations in order to gain users' attention -- and who provide the foundation for its entire business model.

An anonymous reader shares a report: When you ask him about the challenges facing the blockchain system he founded five years ago, Vitalik Buterin often launches into a rapid-fire lecture full of Ethereum-specific jargon. But ask him about his own role in the technology's future, and he quickly becomes more circumspect. There's no doubt that Buterin, 24, is still the guiding light for the idealistic community that has sprung up around his creation. That's been front and center this week in Prague, where thousands of developers, investors, and entrepreneurs have gathered for Devcon, the annual "family reunion" organized by the nonprofit Ethereum Foundation. The most popular discussion topic is Buterin's vision for "Ethereum 2.0," a future iteration meant to be capable of operating efficiently at a much larger scale -- and appeal to a much broader user base -- than it can today. But in a conversation with MIT Technology Review on the sidelines of Devcon, Buterin said it's time for him to start fading into the background as "a necessary part of the growth of the community."

For centuries, science was a multilingual affair, powered by French, German, English and other tongues. But since the early 1970s, English has become the undisputed lingua franca of scientific papers, conferences, and discourse. From a report: English-speaking countries now have a huge leg up in technical research, including the current rages -- artificial intelligence and quantum computing. But, while English is highly unlikely to be dethroned, its advantages are eroding due to an increasingly healthy research environment in China, the fast transmission of research papers across the internet, and AI-aided translation technology that is shrinking the language barrier. [...] The dominance of English gives native speakers a huge advantage, says Michael Gordin, a Princeton professor who specializes in the role of language in technological advance.

Intel processors are impacted by a new vulnerability that can allow attackers to leak encrypted data from the CPU's internal processes. From a report: The new vulnerability, which has received the codename of PortSmash, has been discovered by a team of five academics from the Tampere University of Technology in Finland and Technical University of Havana, Cuba. Researchers have classified PortSmash as a side-channel attack. In computer security terms, a side-channel attack describes a technique used for leaking encrypted data from a computer's memory or CPU, which works by recording and analyzing discrepancies in operation times, power consumption, electromagnetic leaks, or even sound to gain additional info that may help break encryption algorithms and recovering the CPU's processed data. Researchers say PortSmash impacts all CPUs that use a Simultaneous Multithreading (SMT) architecture, a technology that allows multiple computing threads to be executed simultaneously on a CPU core. [...] Researchers say they've already confirmed that PortSmash impacts Intel CPUs which support the company's Hyper-Threading (HT) technology, Intel's proprietary implementation of SMT.
