One Bitcoin Transaction Now Uses As Much Energy As Your House In a Week (vice.com) 227

Long-time Slashdot reader SlaveToTheGrind quotes Motherboard: Bitcoin's incredible price run to break over $7,000 this year has sent its overall electricity consumption soaring, as people worldwide bring more energy-hungry computers online to mine the digital currency. An index from cryptocurrency analyst Alex de Vries, aka Digiconomist, estimates that with prices the way they are now, it would be profitable for Bitcoin miners to burn through over 24 terawatt-hours of electricity annually as they compete to solve increasingly difficult cryptographic puzzles to "mine" more Bitcoins. That's about as much as Nigeria, a country of 186 million people, uses in a year.

This averages out to a shocking 215 kilowatt-hours (KWh) of juice used by miners for each Bitcoin transaction (there are currently about 300,000 transactions per day). Since the average American household consumes 901 KWh per month, each Bitcoin transfer represents enough energy to run a comfortable house, and everything in it, for nearly a week.

How Two Scientists Accurately Predicted Global Warming in 1967 (medium.com) 218

Slashdot reader Layzej shares an article from this spring marking the 50th anniversary of the first accurate climate model: Astrophysicist Ethan Siegel looks at a climate model (MW67) published in 1967 and finds "50 years after their groundbreaking 1967 paper, the science can be robustly evaluated, and they got almost everything exactly right."

An analysis on the "Climate Graphs" blog shows exactly how close the prediction has proven to be: "The slope of the CO2-vs-temperature regression line in the 50 years of actual observations is 2.57, only slightly higher than MW67's prediction of 2.36" They also note that "This is even more impressive when one considers that at the time MW67 was published, there had been no detectable warming in over two decades. Their predicted warming appeared to mark a radical change with the recent past:"

The Computer Scientist Who Prefers Voting With Paper (theatlantic.com) 219

Geoffrey.landis writes: The Atlantic profiles a computer scientist: Barbara Simons, who has been on the forefront of the pushback against electronic voting as a technology susceptible to fraud and hacking. When she first started writing articles about the dangers of electronic voting with no paper trail, the idea that software could be manipulated to rig elections was considered a fringe preoccupation; but Russia's efforts to influence the 2016 presidential election have reversed Simons's fortunes. According to the Department of Homeland Security, those efforts included attempts to meddle with the electoral process in 21 states; while a series of highly publicized hacks -- at Sony, Equifax, the U.S. Office of Personnel Management -- has driven home the reality that very few computerized systems are truly secure. Simons is a former President of the Association for Computing Machinery (ACM); and the group she helps run, Verified Voting, has been active in educating the public about the dangers of unverified voting since 2003.

Nintendo Reportedly Plans To Double Switch Production In 2018 (engadget.com) 42

An anonymous reader quotes a report from Engadget: The Switch, Nintendo's latest hybrid console is doing pretty well for the company, which expects it to outdo the Wii U's lifetime sales within a year. The company obviously thinks so, too, according to a new report at The Wall Street Journal, which says that Nintendo plans to ramp up production of the hardware itself, beginning in April 2018. The report claims that Nintendo is planning to make 25 million to 30 million more units of its successful Switch console over the next fiscal year. Further, Nintendo may plan for even more if this year's holiday sales are strong, according to the WSJ's sources. The company has already built almost 8 million Switches, total, as of its latest earnings report.

NASA Discovers Mantle Plume That's Melting Antarctica From Below (newsweek.com) 244

schwit1 shares a report from Newsweek: Researchers at NASA have discovered a huge upwelling of hot rock under Marie Byrd Land, which lies between the Ross Ice Shelf and the Ross Sea, is creating vast lakes and rivers under the ice sheet. The presence of a huge mantle plume could explain why the region is so unstable today, and why it collapsed so quickly at the end of the last Ice Age, 11,000 years ago. Mantle plumes are thought to be part of the plumbing systems that brings hot material up from Earth's interior. Once it gets through the mantle, it spreads out under the crust, providing magma for volcanic eruptions. The area above a plume is known as a hotspot.

[I]n a study published in the Journal of Geophysical Research: Solid Earth, Seroussi and colleagues looked at one of the most well studied magma plumes on Earth -- the Yellowstone hotspot. The team developed a mantle plume model to look at how much geothermal heat would be needed to explain what is seen at Marie Byrd Land. They then used the Ice Sheet System Model (ISSM), which shows the physics of ice sheets, to look at the natural sources of heating and heat transport. This model enabled researchers to place "powerful constraint" on how much melt rate was allowable, meaning they could test out different scenarios of how much heat was being produced deep beneath the ice. Their findings showed that generally, the energy being generated by the mantle plume is no more than 150 milliwatts per square meter -- any more would result in too much melting. The heat generated under Yellowstone National Park, on average, is 200 milliwatts per square meter.

Paradise Papers Expose Canadian Scalper's Multimillion-Dollar StubHub Scheme (www.cbc.ca) 146

An anonymous reader quotes a report from CBC.ca: When Adele fans went online to buy tickets to the pop superstar's world tour last year, they had no idea what exactly they were up against. An army of tech-savvy resellers that included a little-known Canadian superscalper named Julien Lavallee managed to vacuum up thousands of tickets in a matter of minutes in one of the quickest tour sellouts in history. The many fans who were shut out would have to pay scalpers like Lavallee a steep premium if they still wanted to see their favorite singer. An investigation by CBC/Radio-Canada and the Toronto Star, based in part on documents found in the Paradise Papers, rips the lid off Lavallee's multimillion-dollar operation based out of Quebec and reveals how ticket website StubHub not only enables but rewards industrial-scale scalpers who gouge fans around the world.

Lavallee's name appears over and over in the records, alongside the names of his wife, his father and other friends and family. The records show them somehow buying tickets from different locations around the world at the same time, placing orders from cities like Chicago, Los Angeles, London and Montreal. Lavallee, who got his start in his early 20s reselling hockey and concert tickets while living at home with his parents, now runs an international ticket harvesting operation. Financial records detail $7.9 million in gross sales in 2014 alone. [T]he CBC/Star investigation also discovered a password-protected portal exclusively for StubHub's top sellers who prove they can move more than $50,000 worth of tickets a year. The company offers them special software to upload and manage huge inventories of tickets.
StubHub said in a statement: "StubHub agrees that the use of bots to procure tickets is unfair and anti-consumer. StubHub has always supported anti-bots legislation and encourages policy-makers to look comprehensively at the host of factors that impact a fan's ability to fairly access, buy, resell, or even give away tickets in a competitive ticket market."

Ford Pilots a New Exoskeleton To Lessen Worker Fatigue (futurism.com) 48

Ford is partnering with California-based exoskeleton maker Ekso Bionics to trial a non-powered upper body exoskeletal tool called EksoVest in two of the carmaker's U.S. plants. The goal is to lessen the fatigue factory workers experience in Ford's car manufacturing plants. Futurism reports: Designed to fit workers from five feet to six feet four inches tall, the EksoVest adds some 3 to 6 kilograms (5 to 15 pounds) of adjustable lift assistance to each arm. This exoskeleton is also comfortable enough to wear while providing free arm movement thanks to its lightweight construction. "Collaboratively working with Ford enabled us to test and refine early prototypes of the EksoVest based on insights directly from their production line workers," Ekso Bionics co-founder and CTO Russ Angold said in a Ford press release. "The end result is a wearable tool that reduces the strain on a worker's body, reducing the likelihood of injury, and helping them feel better at the end of the day -- increasing both productivity and morale." The U.S. trial, made possible with the help of the United Automobile Workers, has already demonstrated the wonders that the exoskeleton can offer in reducing fatigue from high-frequency tasks. As such, Ford plans to expand their EksoVest pilot program to other regions, which include Europe and South America.

Sex Toy Company Admits To Recording Users' Remote Sex Sessions, Calls It a 'Minor Bug' (theverge.com) 81

According to Reddit user jolioshmolio, Hong Kong-based sex toy company Lovense's remote control vibrator app (Lovense Remote) recorded a use session without their knowledge. "An audio file lasting six minutes was stored in the app's local folder," reports The Verge. "The user says he or she gave the app access to the mic and camera but only to use with the in-app chat function and to send voice clips on command -- not constant recording when in use." The app's behavior appears to be widespread as several others confirmed it too. From the report: A user claiming to represent Lovense responded and called this recording a "minor bug" that only affects Android users. Lovense also says no information or data was sent to the company's servers, and that this audio file exists only temporarily. An update issued today should fix the bug. This isn't Lovense's first security flub. Earlier this year, a butt plug made by the company -- the Hush -- was also found to be hackable. In the butt plug's case, the vulnerability had to do with Bluetooth, as opposed to the company spying on users.

Some iPhone X Displays Plagued By Mysterious 'Green Line of Death' (thenextweb.com) 76

Some iPhone X owners are reporting a random green line appearing on their displays. According to The Next Web, "the defect has already started to take on the endearing 'Green Line of Death' moniker." From the report: Several users across Apple forums and social media have reported the error -- I've counted over a dozen accounts, and MacRumors mentions it's read "at least 25" such reports. Oddly, the issue doesn't appear to affect users immediately, only showing up after some time with regular usage. In some cases it alternates with a purple line, for variety. It generally appears towards the right or left sides of the display, and sometimes it simply disappears altogether. Weird. Either way, it appears to be a hardware defect affecting a small number of users, and Apple appears to be replacing affected units. Mac Rumors first reported the issue.

This Time, Facebook Is Sharing Its Employees' Data (fastcompany.com) 45

tedlistens writes from a report via Fast Company: "Facebook routinely shares the sensitive income and employment data of its U.S.-based employees with the Work Number database, owned by Equifax Workforce Solutions," reports Fast Company. "Every week, Facebook provides an electronic data feed of its employees' hourly work and wage information to Equifax Workforce Solutions, formerly known as TALX, a St. Louis-based unit of Equifax, Inc. The Work Number database is managed separately from the Equifax credit bureau database that suffered a breach exposing the data of more than 143 million Americans, but it contains another cache of extensive personal information about Facebook's employees, including their date of birth, social security number, job title, salary, pay raises or decreases, tenure, number of hours worked per week, wages by pay period, healthcare insurance coverage, dental care insurance coverage, and unemployment claim records."

Surprisingly, Facebook is among friends. Every payroll period, Amazon, Microsoft, and Oracle provide an electronic feed of their employees' hourly work and wage information to Equifax. So do Wal-Mart, Twitter, AT&T, Harvard Law School, and the Commonwealth of Pennsylvania. Even Edward Snowden's former employer, the sometimes secretive N.S.A. contractor Booz Allen Hamilton, sends salary and other personal data about its employees to the Equifax Work Number database. It now contains over 296 million employment records for employees at all wage levels, from CEOs to interns. The database helps streamline various processes for employers and even federal government agencies, says Equifax. But databases like the Work Number also come with considerable risks. As consumer journalist Bob Sullivan puts it, Equifax, "with the aid of thousands of human resource departments around the country, has assembled what may be the most powerful and thorough private database of Americans' personal information ever created." On October 8, a month after Equifax announced its giant data breach, security expert Brian Krebs uncovered a gaping hole in the separate Work Number online consumer application portal, which allowed anyone to view a person's salary and employment history "using little more than someone's Social Security number and date of birth -- both data elements that were stolen in the recent breach at Equifax."

China Says Foreign Firms Won't Be Forced To Turn Over Technology (vice.com) 40

An anonymous reader quotes a report from Bloomberg: A top Communist Party official said Friday that China won't force foreign companies to turn over technology secrets to gain market access, signaling attention to a key sticking point with U.S. President Donald Trump as he prepared to leave Beijing. The statement by Chinese Vice Premier Wang Yang, the Communist Party's No. 4 official, was made in an article published in the People's Daily newspaper under his byline. While other Chinese officials have made similar pledges in the past about foreign technology, Wang's statement stands out for the seniority of the person making it and its timing. In his article, Wang also pledged to improve the foreign investment environment and treat all companies equally. China will also increase access to its services and manufacturing sectors, wrote Wang, who was last month promoted to the country's top-decision making body, the Politburo Standing Committee.

EA Buys Out a Game Studio After Shutting Another One Down 3 Weeks Ago (arstechnica.com) 57

EA has acquired the video game studio Respawn Entertainment. "The studio, co-founded by former Infinity Ward chiefs and Call of Duty co-creators in the wake of their departure from Activision, has been bought out in a deal whose total value could reach $455 million," reports Ars Technica. "The news by itself may seem odd, considering that EA shut down one of its other wholly owned studios, Visceral Games, only three weeks ago." From the report: A report from Kotaku sheds light on why EA made the move: as a response to another game publisher, Korea's Nexon, making a formal bid to buy Respawn outright. Nexon currently publishes a mobile spinoff of Respawn's Titanfall shooter series. Kotaku, citing sources close to the matter, claims that Nexon had bid to buy the company outright. EA exercised its contractual right to match the offer, Kotaku says, and it ultimately outbid Nexon. Among other things, the buyout preserves Respawn's continued work on an upcoming EA game set in the Star Wars universe; EA currently enjoys an exclusive license to making Star Wars-related video games, and any takeover by another company would have to resolve whether or how such a project would continue in production. Respawn's Star Wars project still does not have a title, a release date, or revealed gameplay footage. Respawn announced its work on an additional, unnamed VR game at Oculus Connect 4 last month; the EA statement says that project will continue apace, as well.

Following Equifax Breach, CEO Doesn't Know If Data Is Encrypted (techtarget.com) 104

An anonymous reader quotes a report from TechTarget: Equifax alerted the public in September 2017 to a massive data breach that exposed the personal and financial information -- including names, birthdays, credit card numbers and Social Security numbers -- of approximately 145 million customers in the United States to hackers. Following the Equifax breach, the former CEO Richard Smith and the current interim CEO Paulino do Rego Barros Jr. were called to testify before the Committee on Commerce, Science, and Transportation this week for a hearing titled "Protecting Consumers in the Era of Major Data Breaches." During the hearing, Sen. Cory Gardner (R-Colo.) questioned Smith and Barros about Equifax's use of -- or lack of -- encryption for customer data at rest. Smith confirmed that the company was not encrypting data at the time of the Equifax breach, and Gardner questioned whether or not that was intentional. "Was the fact that [customer] data remained unencrypted at rest the result of an oversight, or was that a decision that was made to manage that data unencrypted at rest?" Gardner asked Smith. Smith pointed out that encryption at rest is just one method of security, but eventually confirmed that a decision was made to leave customer data unencrypted at rest. "So, a decision was made to leave it unencrypted at rest?" Gardner pushed. "Correct," Smith responded.

Gardner moved on to Barros and asked whether he has implemented encryption for data at rest since he took over the position on Sept. 26. Barros began to answer by saying that Equifax has done a "top-down review" of its security, but Gardner interrupted, saying it was a yes or no question. Barros stumbled again and said it was being reviewed as part of the response process and Gardner pushed again. "Yes or no, does the data remain unencrypted at rest?" "I don't know at this stage," Barros responded. "Senator, if I may. It's my understanding that the entire environment [in] which this criminal attack occurred is much different; it's a more modern environment with multiple layers of security that did not exist before. Encryption is only one of those layers of security," Smith said.

Here Comes the World's Biggest Shopping Spree -- Again (bloomberg.com) 38

A reader shares a report: On Nov. 11, China celebrates Singles Day, a holiday dedicated to the nation's unattached. It's also the world's largest shopping festival -- and a bonanza for internet giant Alibaba Group. Up to 500 million consumers will visit sites run by the company searching for discounts on items including Bordeaux wine, UGG boots, SUVs, and high-end Japanese toilets. Citigroup estimates that Alibaba's sales during this year's event could reach 158 billion yuan ($23.8 billion). For Alibaba, Singles Day will also be a demonstration of how far its cloud business has come in eight years. At the peak of activity, Alibaba's servers may be tasked with processing 175,000 transactions a second from its own sites. "It's the day when the largest amount of computing power is needed in China," says He Yunfei, a senior product manager for Alibaba Cloud. [...] Alibaba dominates the Chinese cloud -- in part because local regulators won't issue data center operating licenses to foreign companies, curtailing the China ambitions of Amazon.com and Microsoft, the No. 1 and No. 2 cloud providers globally.
