Screen Time Changes Structure of Kids' Brains, NIH Study Shows

Slashdot - Sat, 12/15/2018 - 10:34
schwit1 shared this article from Bloomberg: Brain scans of adolescents who are heavy users of smartphones, tablets and video games look different from those of less active screen users, preliminary results from an ongoing study funded by the National Institutes of Health show, according to a report on Sunday by "60 Minutes." That's the finding of the first batch of scans of 4,500 nine- to 10-year-olds. Scientists will follow those children and thousands more for a decade to see how childhood experiences, including the use of digital devices, affect their brains, emotional development and mental health. In the first round of testing, the scans of children who reported daily screen usage of more than seven hours showed premature thinning of the brain cortex, the outermost layer that processes information from the physical world.... Early results from the $300 million study, called Adolescent Brain Cognitive Development (ABCD), have determined that children who spend more than two hours of daily screen time score lower on thinking and language tests. A major data release is scheduled for early 2019. The study's director cautions that "It won't be until we follow them over time that we will see if there are outcomes that are associated with the differences that we're seeing in this single snapshot." The study will ultimately follow over 11,000 nine- to 10-year-olds for a decade.

OpenJDK Bug Report Complains Source Code 'Has Too Many Swear Words'

Slashdot - Sat, 12/15/2018 - 09:34
Thursday a bug report complained that the source code for OpenJDK, the free and open-source implementation of Java, "has too many swear words." An anonymous reader writes: "There are many instances of swear words inside OpenJDK jdk/jdk source, scattered all over the place," reads the bug report. "As OpenJDK is used in a professional context, it seems inappropriate to leave these 12 instances in there, so here's a changeset to remove them." IBM software developer (and OpenJDK team member and contributor) Adam Farley responded that "after discussion with the community, three determinations were reached": "Damn" and "Crap" are not swear words. Three of the four f-bombs are located in jszip.js, which should be corrected upstream (will follow up). The f-bomb in BitArray.java, as well as the rude typo in SoftChannel.java, *are* swear words and should be removed to resolve this work item. He promised a new webrev would be uploaded to reflect these determinations, and the bug has been marked as "resolved."

Could You Live Without a Smartphone For a Year?

Slashdot - Sat, 12/15/2018 - 07:00
shanen writes about Vitaminwater's latest "publicity stunt," where they will pay $100,000 to one select contestant who can live without their smartphone for a year: All you have to do is come up with the most amusing entry [about how you will spend 365 days without the device] and have sufficient willpower to give up your smartphone for a year. They obviously have to pick a power user to make it interesting, but that's not the reason I'm disqualified. I would just read more books, which is boring from their perspective. So maybe you want to share your idea here? If it's really good, you don't have to worry about someone stealing it. After all, you'd have the evidence that it was your idea first, but you might be able to refine your entry while amusing the mob. The company will reportedly give you a 1996 cellphone to use in times of emergencies. Also, they will reward you with $10,000 if you are able to get through 6 months. According to Tech Times, contestants can use computers or desktops, "but not smartphones or tablets, even those owned by other people, or anything which the candidate can scroll or swipe on." Always-listening smart speakers, like the Amazon Echo and Google Home, are permitted. To make sure the candidate doesn't cheat, Vitaminwater will subject them to a lie-detector test at the end of the year.

Tesla Model 3 Modded To Run Ubuntu

Slashdot - Sat, 12/15/2018 - 04:00
140Mandak262Jamuna writes: CleanTechnica is reporting that someone hacked the infotainment system of a Tesla Model 3 and got root access and installed Linux distribution Ubuntu. Redditor trsohmers is able to show an Ubuntu command shell running alongside the Tesla OS. Since Tesla supports a browser that allows you to visit any site, could this be leveraged into remote hacks? It could also mean that if Tesla sells a long-range version of the Model 3, but limits it via software, people might try to remove the block. One could potentially get a 15-day trial of full self-driving for free and extend that 15-day window forever. At least he had some guts messing with $50,000 hardware that phones home all the time. Will Tesla brick his car to attempt to disprove the security issue?

Protecting the world's oceans with open data science

LXer - Sat, 12/15/2018 - 03:31
For environmental scientists, researching a single ecosystem or organism can be a daunting task. The amount of data and literature to comb through (or create) is often overwhelming.So how, then, can environmental scientists approach studying the health of the world’s oceans? What ocean health means is a big question in itself—oceans span millions of square miles, are home to countless species, and border hundreds of countries and territories, each of which has its own unique marine policies and practices.read more

NASA's Hubble Telescope Discovers An 'Evaporating' Planet

Slashdot - Sat, 12/15/2018 - 01:00
Researchers at the University of Geneva Switzerland have used NASA's Hubble telescope to find an exoplanet that's evaporating. The exoplanet, GJ 3470b, shows signs of losing hydrogen in its atmosphere, causing it to shrink. USA Today reports: The study is part of exploration into "hot Neptunes," planets that are the size of Neptune, sit very close to their star, and have atmospheres as hot at 1,700 degrees Fahrenheit, says NASA. Finding a "hot Neptune" is rare because they sit so close to their star and tend to evaporate more quickly. In the case of GJ 3470b, scientists classify it as a "warmer" Neptune because it sits farther away from its star. The exoplanet discovered by astronauts is losing its atmosphere at a rate 100 times faster than a previous "warmer" Neptune planet discovered a few years before, according to a study published Thursday in the journal "Astronomy & Astrophysics." The planet sits 3.7 million miles from its star. For comparison, Earth is 92.9 million miles from the sun. Researchers say these "hot Neptune" planets shrink in size and morph into "Super Earths," versions of our planet that are massive and more rocky.

Experts Urge US To Continue Support For Nuclear Fusion Research

Slashdot - Fri, 12/14/2018 - 21:30
An anonymous reader quotes a report from Scientific American: A panel of 19 scientists drawn from the National Academies of Sciences, Engineering and Medicine recommended yesterday that the Department of Energy should continue an international experiment on nuclear fusion energy and then develop its own plan for a "compact power plant." A panel of 19 scientists drawn from the National Academies of Sciences, Engineering and Medicine recommended yesterday that the Department of Energy should continue an international experiment on nuclear fusion energy and then develop its own plan for a "compact power plant." But as the National Academies' report noted, major challenges must be overcome to reach these goals, beginning with how to contain and control a burning "plasma" of extremely hot gas, ranging from 100 million to 200 million degrees Celsius, that can produce more heat than it consumes. The report calls the resulting plasma "a miniature sun confined inside a vessel." The world's biggest experiment intended to create and draw energy from burning plasma is under construction at Cadarache, France. It's called the International Thermonuclear Experimental Reactor (ITER) project, and its centerpiece is a large, doughnut-shaped, Russian-inspired reactor called a tokamak. Several member nations have already developed their own national programs, and the assembled National Academies experts concluded that the United States should eventually follow, once the ITER experiment shows there are ways to contain and manipulate a sustained fusion reaction. "It is the next critical step in the development of fusion energy," says the report.

Number of Streaming Shows Overtakes Basic Cable, Broadcast For First Time

Slashdot - Fri, 12/14/2018 - 20:20
schwit1 shares a report from Variety: Streaming services snatched their biggest piece of the TV pie ever in 2018. According to FX's annual report on the number of scripted originals on TV, the number of streaming shows has surpassed the number of basic cable and broadcast shows for the first time ever. Out of 495 scripted originals that aired in 2018, 160 of them did so on a streaming platform. That is compared to 146 on broadcast and 144 on basic cable. Pay cable accounted for the remaining 45 shows. Streaming shows also saw the biggest increase year-to-year, growing from 117 last year. Broadcast dipped slightly, dropping from 153 in 2017. Basic cable saw a more sharp decline, compared to the 175 shows that aired on basic cable the previous year. Pay cable was up slightly from 42. On a percentage basis, streaming shows now account for approximately one third of all scripted originals, with approximately 32%. Broadcast made up 30% and basic cable 29%, with pay cable making up 9%. The total number of shows across all of TV was up again as well, rising from 487 in 2017. The year-to-year growth was less than that of previous years, however. For example, the number of shows grew from 455 to 487 between 2016 and 2017. The 495 scripted originals this year was also off from FX Networks CEO John Landgraf's prediction that 520 such shows would air this year.

Cloudflare Under Fire For Allegedly Providing DDoS Protection For Terrorist Websites

Slashdot - Fri, 12/14/2018 - 19:40
Cloudflare is facing accusations that it's providing cybersecurity protection for at least seven terrorist organizations. "On Friday, HuffPost reported that it has reviewed numerous websites run by terrorist organizations and confirmed with four national security and counter-extremism experts that the sites are under the protection of Cloudflare's cybersecurity services," reports Gizmodo. "Among Cloudflare's millions of customers are several groups that are on the State Department's list of foreign terrorist organizations, including al-Shabab, the Popular Front for the Liberation of Palestine, al-Quds Brigades, the Kurdistan Workers' Party (PKK), al-Aqsa Martyrs Brigade and Hamas -- as well as the Taliban, which, like the other groups, is sanctioned by the Treasury Department's Office of Foreign Assets Control (OFAC)," reports HuffPost. "In the United States, it's a crime to knowingly provide tangible or intangible 'material support -- including communications equipment -- to a designated foreign terrorist organization or to provide service to an OFAC-sanctioned entity without special permission," the report continues. "Cloudflare, which is not authorized by the OFAC to do business with such organizations, has been informed on multiple occasions, dating back to at least 2012, that it is shielding terrorist groups behind its network, and it continues to do so." Gizmodo reports: The issue that HuffPost raises is whether Cloudflare is providing "material support" to sanctioned organizations. Some attorneys told HuffPost that it may be in violation of the law. Others, like the Electronic Frontier Foundation, argue that "material support" can and has been abused to silence speech. Cloudflare's general counsel, Doug Kramer, told Gizmodo over the phone that the company works closely with the U.S. government to ensure that it meets all of its legal obligations. He said that it is "proactive to screen for sanctioned groups and reactive to respond when its made aware of a sanctioned group" to which it may be providing services. HuffPost spoke with representatives from the Counter Extremism Project, who expressed frustration that they've sent four letters to Cloudflare over the last two years identifying seven terrorist-operated sites without receiving a reply. Kramer would not address any specific customers or situations when speaking with Gizmodo. He said that's simply company policy for reasons of protecting privacy.

Porn Sites Collect More User Data Than Netflix Or Hulu

Slashdot - Fri, 12/14/2018 - 19:00
An anonymous reader quotes a report from Quartz: The biggest and perhaps best source of data about what people like to watch on the internet and what they would pay for doesn't come from streaming giants like Netflix, Amazon Prime Video, or Hulu. It comes from porn. While consuming porn is typically a private and personal affair, porn sites still track your every move: What content you choose, which moments you pause, which parts you repeat. By mining this data to a deeper degree than other streaming services, many porn sites are able to give internet users exactly what they want -- and they want a lot of it. [...] MindGeek is the world's biggest porn company -- more specifically, it's a holding company that owns numerous adult entertainment sites and production companies, including the Pornhub Network. Like other streaming giants, MindGeek's sites analyze user data, but the company has an edge when it comes to producing tailor-made content in-house. With at least 125 million daily visits, MindGeek has a massive range of users to draw data from and create content for. The average user can watch as much porn as they'd like without so much as making an account, let alone paying, but in exchange for meeting desires that can't always be met elsewhere, companies like MindGeek access user data because the user more willingly lets them. And it eventually pays off, when users decide to pay for premium content and the habits of paying subscribers become even clearer. What's more, Pornhub, in particular, operates one of the most sophisticated digital data analysis operations that caters primarily to users and not advertisers. Pornhub Insights provides transparency into its data collection -- on the most intimate of subjects -- by making research and analysis from billions of data points about viewership patterns, often tied to events from politics to pop culture, available to the public. It offers more than many other tech giants do.
