The U.S. government may begin charging users for access to five decades of satellite images of Earth. Quartz reports: Nature reports that the Department of Interior has asked an advisory board to consider the consequences of charging for the data generated by the Landsat program, which is the largest continuously collected set of Earth images taken in space and has been freely available to the public since 2008. Since 1972, Landsat has used eight different satellites to gather images of the Earth, with a ninth currently slated for a December 2020 launch. The data are widely used by government agencies, and since it became free, by an increasing number of academics, private companies and journalists. "As of March 31, 2018, more than 75 million Landsat scenes have been downloaded from the USGS-managed archive!" the agency noted on the 10th anniversary of the program. Now, the government says the cost of sharing the data has grown as more people access it. Advocates for open data say the public benefit produced through research and business activity far outweigh those costs. A 2013 survey cited by Nature found that the dataset generated $2 billion in economic activity, compared to an $80 million budget for the program.Read Replies (0)

Unless you've been living under a rock for the past few days, you've probably heard about the controversy over "Yanny" and "Laurel." The internet has been abuzz over an audio clip in which the name being said depends on the listener. Some hear "Laurel" while others hear "Yanny." Ian Vargo, an audio enthusiast who spends most of his working hours of the day listening to and editing audio, helps explain why we hear the name that we do: Human speech is actually composed of many frequencies, in part because we have a resonant chest cavity which creates lower frequencies, and the throat and mouth which creates higher frequencies. The word "laurel" contains a combination of both which are therefore present in the original recording at vocabulary.com, but the clip that you most likely heard has accentuated higher frequencies due to imperfections in the audio that were created by data compression. To make it worse, the playback device that many people first heard the audio clip playing out of was probably a speaker system built into a cellular phone, which is too small to accurately recreate low frequencies.
This helpful interactive tool from The New York Times allows you to use a slider to more clearly hear one or the other. Pitch shifting the audio clip up seems to accentuate "laurel" whereas shifting it down accentuates "yanny." In summary, this perfect storm of the human voice creating both low and high frequencies, the audio clip having been subject to data compression used to create smaller, more convenient files, and our tendency to listen out of devices with subpar playback components lead to an apparent near-even split of the population hearing "laurel" or "yanny."Read Replies (0)

An anonymous reader quotes a report from NPR: The birthrate fell for nearly every group of women of reproductive age in the U.S. in 2017, reflecting a sharp drop that saw the fewest newborns since 1978, according to a new report by the Centers for Disease Control and Prevention. There were 3,853,472 births in the U.S. in 2017 -- "down 2 percent from 2016 and the lowest number in 30 years," the CDC said. The general fertility rate sank to a record low of 60.2 births per 1,000 women between the ages of 15 and 44 -- a 3 percent drop from 2016, the CDC said in its tally of provisional data for the year. The results put the U.S. further away from a viable replacement rate -- the standard for a generation being able to replicate its numbers. "The rate has generally been below replacement since 1971," according to the report from CDC's National Center for Health Statistics. "The decline in the rate from 2016 to 2017 was the largest single-year decline since 2010," the CDC said. The 2017 numbers also represent a 10-year fall from 2007, when the U.S. finally broke its post-World War baby boom record, with more than 4.3 million births.Read Replies (0)

Ars Technica's Kyle Orland shares his experience with Valve's recently announced Steam Link app, which lets users play games running on a PC via a tablet, mobile phone, or Apple TV on the same network. The app launches today for Android 5.0+ devices; iOS support is "pending further review from Apple." From the report: Valve isn't kidding when it says a Wi-Fi router in the 5Ghz band is required for wireless streaming. I first tested iPad streaming on the low-end 2.4Ghz router provided with my Verizon FiOS subscription (an Actiontec MI424WR), with a wired Ethernet connection to my Windows gaming rig on the other end. The Steam Link network test warned me that "your network may not work well with Steam Link," thanks to 1- to 2-percent frame loss and about 15ms of "network variance," depending on when I tested. Even graphically simple games like The Binding of Isaac ran at an unplayably slowed-down rate on this connection, with frequent dropped inputs to boot.
Switching over to a 5GHz tri-band router (The Netgear Nighthawk X6, to be precise), the same network test reported a "fantastic" connection that "look[s] like it will work well with Steam." On this router, remotely played games ran incredibly smoothly at the iPad's full 1080p resolution, with total round-trip display latency ranging anywhere from 50 to 150ms, according to Steam Link's reports (and one-way "input lag" of less than 1ms). At that level of delay, playing felt practically indistinguishable from playing directly on the computer, with no noticeable gameplay impact even on quick-response titles like Cuphead.Read Replies (0)

A new Xbox controller designed for people with disabilities has been announced by Microsoft today. The Xbox Adaptive Controller features two large programmable buttons and 19 jacks that can be connected to a range of joysticks, buttons, and switches to make it easier for a wider range of people to play games on Xbox One and Windows 10 PCs. The Verge reports: "I can customize how I interface with the Xbox Adaptive Controller to whatever I want," says Solomon Romney, a Microsoft Store learning specialist who was born without fingers on his left hand. "If I want to play a game entirely with my feet, I can. I can make the controls fit my body, my desires, and I can change them anytime I want. You plug in whatever you want and go. It takes virtually no time to set it up and use it. It could not be simpler."
The focus is on connectivity and customizability, with players able to build a setup that works for their capabilities and needs. It won't be an all-in-one solution for many games, but through the use of peripherals and the Xbox's system-level button remapping, the possibilities could be endless. The Xbox Adaptive Controller will cost $99.99 and goes on sale later this year.Read Replies (0)

An anonymous reader quotes a report from The New York Times: The Kilauea volcano erupted from its summit on Thursday morning (Warning: source may be paywalled; alternative source), spewing an ash plume that reached 30,000 feet above the island of Hawaii, the authorities said. The eruption was the most forceful new explosion so far at Kilauea, one of the world's most active volcanoes. Kilauea has already been triggering small earthquakes, creating gas-emitting fissures and releasing flows of lava that have destroyed dozens of homes this month. The Hawaiian Volcano Observatory issued a "code red" warning that additional activity could be expected. "At any time, activity may again become more explosive, increasing the intensity of ash production and producing ballistic projectiles near the vent," the observatory said. But Dr. Michelle Coombs of the United States Geological Survey said that ash fall from the eruption, which occurred shortly after 4 a.m., was "pretty limited" to the area around Hawaii Volcanoes National Park. She emphasized that the new eruption wasn't the "big one" that some are fearing, drawing a contrast with the eruption in 1980 of Mount St. Helens in Washington State that killed 57 people.Read Replies (0)

Earlier this week, ZDNet shed some light on a company called LocationSmart that is buying your real-time location data from four of the largest U.S. carriers in the United States. The story blew up because a former police sheriff snooped on phone location data without a warrant, according to The New York Times. ZDNet is now reporting that the company "had a bug in its website that allowed anyone to see where a person is located -- without obtaining their consent." An anonymous reader shares an excerpt: "Due to a very elementary bug in the website, you can just skip that consent part and go straight to the location," said Robert Xiao, a PhD. student at the Human-Computer Interaction Institute at Carnegie Mellon University, in a phone call. "The implication of this is that LocationSmart never required consent in the first place," he said. "There seems to be no security oversight here." The "try" website was pulled offline after Xiao privately disclosed the bug to the company, with help from CERT, a public vulnerability database, also at Carnegie Mellon. Xiao said the bug may have exposed nearly every cell phone customer in the U.S. and Canada, some 200 million customers. The researcher said he started looking at LocationSmart's website following ZDNet's report this week, which followed from a story from The New York Times, which revealed how a former police sheriff snooped on phone location data without a warrant. The sheriff has pleaded not guilty to charges of unlawful surveillance. He said one of the APIs used in the "try" page that allows users to try the location feature out was not validating the consent response properly. Xiao said it was "trivially easy" to skip the part where the API sends the text message to the user to obtain their consent. "It's a surprisingly simple bug," he said.Read Replies (0)

The mayor of New York City, Bill de Blasio, has announced the formation of a new task force to examine the fairness of the algorithms used in the city's automated systems. From a report: The Automated Decision Systems Task Force will review algorithms that are in use to determine that they are free from bias. Representatives from the Department of Social Services, the NYC Police Department, the Department of Transportation, the Mayor's Office of Criminal Justice, the Administration for Children's Services, and the Department of Education will be involved, and the aim is to produce a report by December 2019. However, it may be some time before the task force has any sort of effect. While a report is planned for the end of next year, it will merely recommend "procedures for reviewing and assessing City algorithmic tools to ensure equity and opportunity" -- it will be a while before any recommendation might be assessed and implemented.Read Replies (0)
