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.Read Replies (0)

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.Read Replies (0)

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.Read Replies (0)

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."

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.Read Replies (0)

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.

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.Read Replies (0)

Exit Interview: Scott Kelly

An excerpt from a new interview of Scott Kelly, now a retired astronaut, who spent 11 months and three days at the International Space Station in one stretch: Q: What does space smell like? It smells different to different people. Some people say it smells sweet. To me it smells like burnt metal, like if you took a blowtorch to some steel or something. Q: When you're up there on the ISS, arguably you're the most expensive human being on the planet except the president. The amount of resources being spent to keep you alive are enormous. Did that weigh on you at all? Never even thought about that. No. Never considered it. I appreciated the effort that people went through to make sure you're safe, and are taken care of and supported while you're there, but I never considered the cost of it. Question: Did it feel like, 'Man, I gotta work all the time'? I think some people feel that way. I kind of felt that way on my [first, six-month ISS mission]. But having flown for six months, and then a few years later flying for a year, I realized I couldn't do that. So I definitely had to pace myself throughout the course of the year. Q: Did you lose anything in the station?All kinds of stuff! One of the last things I remember losing was this fancy, 3-D printed cover for some experiment. It was for the camera and I turn around and the thing's gone, and they didn't have a spare. I've got to see if they've found that thing yet. Oh, yeah. We lost a bag of screws and washers one time. Question: When you're on the U.S. side of the ISS and the Russians are on their side, how much interaction is there, day-to-day? They work predominantly in the Russian segment and have their meals there, so during waking hours, they're generally on their side, we're generally on our side. You interact, you go down there, you chat with them, you come back, you might perform some kind of experiments, they might do a little thing in our space station, but it's what we refer to as "segmented ops." Question: Does it feel like you're all in it together? Yes! Absolutely. We actually do some things to help each other that we don't even share with the ground because then it creates like bureaucratic ... issues for them to deal with. I've been asked to help fix some of their hardware, their treadmill one time. We help each other getting trash off the space station without telling the folks in Houston.Read Replies (0)
