YouTube HDR is available for a bunch of new phones

Posted by kenmay on September - 8 - 2017

The Galaxy S8 will already play Netflix in high-dynamic range video, and now the handset (and its cousin, the Note 8 ) is the home for YouTube HDR. Reddit users have had access to the update since yesterday at resolutions up to 1140p60, while SamMobile reports that the publication can only access 1080p60. On our office S8, we’ve seen 1440p60. Google tells us that the Pixel , LG V30 , Sony Xperia XZ Premium have gotten the update as well. More than that, the search juggernaut is working to bring it to even more devices.

Canada’s new radio telescope starts mapping the universe

Posted by kenmay on September - 8 - 2017

On September 7th, an extraordinarily powerful radio telescope in Canada has begun listening to the sounds of the universe. The Canadian Hydrogen Intensity Mapping Experiment or CHIME will help scientists learn more about the history of the cosmos, radio bursts from pulsars and gravitational waves, the ripples in spacetime whose existence were finally confirmed by scientists in 2016. CHIME looks like a collection of four 100-meter-long skateboarding halfpipes, but they weren’t made for anybody to skate on. They were built over the past seven years to hear very weak signals from the universe and to gather one terabyte of information per second all day, every day. That means it’s constantly creating and updating a massive 3D map of space. When the 50 Canadian scientists from the University of British Columbia, the University of Toronto, McGill University and the National Research Council of Canada (NRC) started conceptualizing the project, there was no system that could handle that amount of information. Thanks to advances in video game hardware, the system now exists. Since 1 TB per second is pretty insane, CHIME compresses the info it gathers by a factor of 100, 000 first before saving files on disks. Now that it’s up and working, CHIME is ready to work towards achieving its primary goal: measuring the acceleration of the universe’s expansion. An accurate measurement of the expansion will help scientists figure out what causes it, whether it’s actually the mysterious form of energy that’s believed to be permeating space called ” dark energy ” or something else. By extension, the telescope’s data could one day confirm if dark energy truly exists. University of British Columbia’s Dr. Mark Halpern explains: “With the CHIME telescope we will measure the expansion history of the universe and we expect to further our understanding of the mysterious dark energy that drives that expansion ever faster. This is a fundamental part of physics that we don’t understand and it’s a deep mystery. This is about better understanding how the universe began and what lies ahead.” Source: CHIME

From mid-May to July 2017, Equifax exposed the financial and personal identifying information of 143 million Americans — 44% of the country — to hackers, who made off with credit-card details, Social Security Numbers, sensitive credit history data, driver’s license numbers, birth dates, addresses, and then, in the five weeks between discovering the breach and disclosing it, the company allowed its top execs to sell millions of dollars’ worth of stock in the company , while preparing a risibly defective and ineffective website that provides no useful information to the people whom Equifax has put in grave financial and personal danger through their recklessness.
