Salt Makes You Hungry, Not Thirsty, Study Says

Slashdot Updates - Tue, 04/18/2017 - 2:00pm
wisebabo writes: Salty diet makes you hungry, not thirsty. Science Daily reports: "In a study carried out during a simulated mission to Mars, an international group of scientists has found exactly the opposite to be true. 'Cosmonauts' who ate more salt retained more water, weren't as thirsty, and needed more energy." So if you don't want to gain weight on your trip to Mars, don't eat salty chips. If you don't want to gain weight at home, maybe you should stay away from them as well. From the report: "The studies were carried out by Natalia Rakova (MD, PhD) of the Charite and MDC and her colleagues. The subjects were two groups of 10 male volunteers sealed into a mock spaceship for two simulated flights to Mars. The first group was examined for 105 days; the second over 205 days. They had identical diets except that over periods lasting several weeks, they were given three different levels of salt in their food. The results confirmed that eating more salt led to a higher salt content in urine -- no surprise there. Nor was there any surprise in a correlation between amounts of salt and overall quantity of urine. But the increase wasn't due to more drinking -- in fact, a salty diet caused the subjects to drink less. Salt was triggering a mechanism to conserve water in the kidneys."

User-Made Patch Lets Owners of Next-Gen CPUs Install Updates On Windows 7 & 8.1

Slashdot Updates - Tue, 04/18/2017 - 1:20pm
An anonymous reader quotes a report from BleepingComputer: GitHub user Zeffy has created a patch that removes a limitation that Microsoft imposed on users of 7th generation processors, a limit that prevents users from receiving Windows updates if they still use Windows 7 and 8.1. This limitation was delivered through Windows Update KB4012218 (March 2017 Patch Tuesday) and has made many owners of Intel Kaby Lake and AMD Bristol Ridge CPUs very angry last week, as they weren't able to install any Windows updates. Microsoft's move was controversial, but the company did its due diligence, and warned customers of its intention since January 2016, giving users enough time to update to Windows 10, move to a new OS, or downgrade their CPU, if they needed to remain on Windows 7 or 8.1 for various reasons. When the April 2017 Patch Tuesday came around last week, GitHub user Zeffy finally had the chance to test four batch scripts he created in March, after the release of KB4012218. His scripts worked as intended by patching Windows DLL files, skipping the CPU version check, and delivering updates to Windows 7 and 8.1 computers running 7th generation CPUs.

Malaysia Air Is First Airline to Track Fleet With Satellites

Slashdot Updates - Tue, 04/18/2017 - 12:35pm
From a report: Malaysia Air, which lost a wide-body jet with 239 people aboard three years ago in one of history's most enduring aviation mysteries, has become the first airline to sign an agreement for space-based flight tracking of its aircraft. The subsidiary of Malaysian Airline System Bhd reached a deal with Aireon LLC, SITAONAIR and FlightAware LLC to enable it to monitor the flight paths of its aircraft anywhere in the world including over the polar regions and the most remote oceans, according to an emailed press release from Aireon. Aireon is launching a new satellite network with Iridium Communications Inc. that will allow it to monitor air traffic around the globe. It's projected to be completed in 2018. Most international flights are already transmitting their position with technology known as ADS-B and the signals can be tracked from the ground or space. The U.S. Federal Aviation Administration has already installed a ground-based tracking system for ADS-B. "Real-time global aircraft tracking has long been a goal of the aviation community," Malaysia Chief Operating Officer Izham Ismail said in the release. "We are proud to be the first airline to adopt this solution."

Apple To Launch Three New iPhones This Year: Bloomberg

Slashdot Updates - Tue, 04/18/2017 - 10:02am
Apple is reportedly building three new iPhones, though the one with the most new features might not launch until a couple of months after the others. According to a report on Bloomberg, Apple is testing three new phones that it plans to launch this fall, including two with the same screen sizes as the iPhone 7 and iPhone 7 Plus. The third iPhone, which may be named to help celebrate the 10th anniversary of the original iPhone's launch, is said to pack a new design with a stainless steel frame and curved glass. It's said to feature an embedded fingerprint reader and use OLED panels from Samsung and may have a screen that takes up most of the front of the smartphone's face. From the article: Apple also tested a more ambitious prototype with the same slightly curved front and steel frame, but a glass back with more dramatic curves on the top and bottom like the original iPhone design from 2007, one of the people said.

AMD Launches Higher Performance Radeon RX 580 and RX 570 Polaris Graphics Cards

Slashdot Updates - Tue, 04/18/2017 - 8:43am
Reader MojoKid writes: In preparation for the impending launch of AMD's next-generation Vega GPU architecture, which will eventually reside at the top of the company's graphics product stack, the company unveiled a refresh of its mainstream graphics card line-up with more-powerful Polaris-based GPUs. The new AMD Radeon RX 580 and RX 570 are built around AMD's Polaris 20 GPU, which is an updated revision of Polaris 10. The Radeon RX 580 features 36 Compute Units, with a total of 2,304 shader processors and boost / base GPU clocks of 1340MHz and 1257MHz, respectively, along with 8GB of GDDR5 over a 256-bit interface. The Radeon RX 580 offers up a total of 6.17 TFLOPs of compute performance with up to 256GB/s of peak memory bandwidth. Though based on the same chip, the Radeon RX 570 has only 32 active CUs and 2048 shader processors. Boost and base reference clocks are 1244MHz and 1168MHz, respectively with 4GB of GDDR5 memory also connected over a 256-bit interface. At reference clocks, the peak compute performance of the Radeon RX 570 is 5.1TFLOPs with 224GB/s of memory bandwidth. In the benchmarks, the AMD Radeon RX 580 clearly outpaced AMD's previous gen Radeon RX 480, and was faster than an NVIDIA GeForce GTX 1060 Founder's Edition card more often than not. It was more evenly matched with factory-overclocked OEM GeForce GTX 1060 cards, however. Expected retail price points are around $245 and $175 for 8GB Radeon RX 580 and 4GB RX 570s cards, though more affordable options will also be available.

Google Earth Gets a New Home On the Web

Slashdot Updates - Tue, 04/18/2017 - 7:20am
To celebrate the Earth Day, Google says it is rolling out what was a two-year in the making major update to Google Earth. From a report: V9 is designed to run in a Web browser (just Chrome for now), but there's now a standalone home for Google Earth. The Android app has been updated, too (iOS is coming soon). Version 9 puts a big focus on guided tours via the "Voyager" section, which serves as a jumping off point for YouTube videos, 360-degree content, Street View, and Google Earth landmarks. The tours are led by scientists and documentarians, with some content produced by well-known groups like the BBC's Planet Earth team. For kids, there's a Sesame Street muppet section.

Google's Featured Snippets Are Damaging To Small Businesses that Depend On Search Traffic

Slashdot Updates - Tue, 04/18/2017 - 6:40am
The Outline tells the story of CelebrityNetWorth.com, a website launched in 2008 that tells you how much a celebrity is worth. The site was an instant success, but things have turned sore in the last two years. The creator of the website Brian Warner blames Google for it. From the article: For most of its history, Google was like a librarian. You asked a question, and it guided you to the section of the web where you might find the answer. But over the past five years, Google has been experimenting with being an oracle. Type in a question, and you might see a box at the top of the search results page with the answer in large bold type. [...] In 2014, Warner received an email from Google asking if he would be interested in giving the company access to his data in order to scrape it for Knowledge Graph, for free. He said no, as he feared the traffic would plummet. [...] In February 2016, Google started displaying a Featured Snippet for each of the 25,000 celebrities in the CelebrityNetWorth database, Warner said. He knew this because he added a few fake listings for friends who were not celebrities to see if they would pop up as featured answers, and they did. "Our traffic immediately crumbled," Warner said. He acknowledged the risks in building a site that depends so heavily on Google for search traffic, and whose research can easily be reduced to a single number. But he still thinks what Google did is unfair.

Steve Ballmer's New Project: Find Out How the Government Spends Your Money

Slashdot Updates - Tue, 04/18/2017 - 6:00am
Former Microsoft CEO Steve Ballmer isn't satisfied with owning the Los Angeles Clippers and teaching at Stanford and USC. On Tuesday, the billionaire announced USAFacts, his new startup that aims to improve political discourse by making government financial data easier to access. A small "army" of economists, professors and other professionals will be looking into and publishing data structured similarly to the 10-K filings companies issue each year -- expenses, revenues and key metrics pulled from dozens of government data sources and compiled into a single massive collection of tables. From a report on The Verge: The nonpartisan site traces $5.4 trillion in government spending under four categories derived from language in the US Constitution. Defense spending, for example, is categorized under the header "provide for the common defense," while education spending is under "secure the blessing of liberty to ourselves and our prosperity." Spending allocation and revenue sources are each mapped out in blue and pink graphics, with detailed breakdowns along federal, state and local lines. Users can also search for specific datasets, such as airport revenue or crime rates, and the site includes a report of "risk factors" that could inhibit economic growth. The New York Times has the story on how this startup came to be.

Trump To Overhaul H-1B Visa Program To Encourage Hiring Americans

Slashdot Updates - Tue, 04/18/2017 - 5:00am
An anonymous reader quotes a report from The Guardian: In a bid to court working class voters, Donald Trump will sign an executive order on Tuesday to revamp a temporary visa program used to bring foreign workers to fill jobs in the U.S. The president will use a visit to a manufacturing company in Kenosha, Wisconsin, a crucial state he snatched from Hillary Clinton in the election, to promote his latest "Buy America Hire America" offensive. Trump's executive order will call on government departments to introduce reforms to ensure that H-1B visas are awarded to the "most skilled or highest paid applicants," a senior administration official said. The executive order will also call for the "strict enforcement" of laws governing entry to the U.S. of labor from overseas, with a view to creating higher wages and employment rates for U.S. workers. The order will also call on government departments to "take prompt action to crack down on fraud and abuse" in the immigration system, a senior administration official said. The administration official sad: "Right now H-1B visas are awarded by random lottery and many of you will be surprised to know that about 80% of H-1B workers are paid less than the median wage in their fields. Only 5% to 6%, depending on the year, of H-1B workers command the highest wage tier recognized by the Department of Labor. [...] If you change that current system that awards visas randomly, without regard for skill or wage, to a skills-based awarding, it makes it extremely difficult to use the visa to replace or undercut American workers [...] It's a very elegant way of solving very systemic problems in the H-1B guest worker visa."

Google Agrees To Open Android To Other Search Engines In Russia

Slashdot Updates - Tue, 04/18/2017 - 2:00am
Google has reached a $7.8 million antitrust settlement with Russian watchdog group FAS. According to BGR, the company will loosen restrictions on Android's built-in search engines to allow for Russian competitors to take a share of the pie. From the report: Android's heavy reliance on Google services is to be expected, but in 2015 the Russian antitrust group -- officially the Federal Antimonopoly Service -- ruled that Google was breaking the law by forcing users to lean on Google for search. The ruling was the result of a complaint filed by Yandex, a Russian competitor to Google that runs the largest search engine in the country as well as web mail, news, maps, and other services. Google's settlement of the issue comes with the condition that Android will no longer lock down the search engine to Google, and must allow users the ability to change it if they want from within the Chrome web browser. Google will also loosen its exclusivity of the default apps on Android devices sold in Russia, potentially allowing for Yandex and other regional competitors to muscle in and replace the built-in apps with their own versions, depending on user preference.
