  • Supreme Court Hears Copyright Battle Over Online Music Piracy
    by BeauHD on 02/12/2025 at 2:14 pm

    The Supreme Court appears inclined to side with Cox Communications in a major copyright case, suggesting that ISPs shouldn't be held liable for users' music piracy based solely on "mere knowledge," given the risk of forcing outages for universities, hospitals, and other large customers. The New York Times reports: Leading music labels and publishers who represent artists ranging from Bob Dylan to Beyonce sued Cox Communications in 2018, saying it had failed to terminate the internet connections of subscribers who had been repeatedly flagged for illegally downloading and distributing copyrighted music. At issue is whether providers like Cox can be held legally responsible and be required to pay steep damages -- a billion dollars or more -- if they know that customers are pirating the music but do not take sufficient steps to terminate their internet access. Justices from across the ideological spectrum on Monday raised concerns about whether finding for the music industry could result in internet providers being forced to cut off access to large account holders such as hospitals and universities because of the illegal acts of individual users. "What is the university supposed to do in your view?" asked Justice Samuel A. Alito Jr., a conservative, suggesting it would be difficult to track down bad actors without the risk of losing service campuswide. "I just don't see how it's workable at all." "The internet is so amorphous," added Justice Sonia Sotomayor, a liberal, saying that a single "customer" could represent tens of thousands of users, particularly in rural areas where an entire region might be considered a "customer." After nearly two hours of argument, a majority of justices seemed likely to side with Cox and to send the case back to the U.S. Court of Appeals for the Fourth Circuit for review under a stricter standard. Several justices suggested the company's "mere knowledge" of the illegal downloads was not sufficient to hold Cox liable. Read more of this story at Slashdot.

  • An Independent Effort Says AI Is the Secret To Topple 2-Party Power In Congress
    by BeauHD on 02/12/2025 at 1:13 pm

    Tony Isaac quotes a report from NPR: The rise of AI assistants is rewriting the rhythms of everyday life: People are feeding their blood test results into chatbots, turning to ChatGPT for advice on their love lives and leaning on AI for everything from planning trips to finishing homework assignments. Now, one organization suggests artificial intelligence can go beyond making daily life more convenient. It says it's the key to reshaping American politics. "Without AI, what we're trying to do would be impossible," explained Adam Brandon, a senior adviser at the Independent Center, a nonprofit that studies and engages with independent voters. The goal is to elect a handful of independent candidates to the House of Representatives in 2026, using AI to identify districts where independents could succeed and uncover diamond in the rough candidates. [...] ... "This isn't going to work everywhere. It's going to work in very specific areas," [said Brett Loyd, who runs The Bullfinch Group, the nonpartisan polling and data firm overseeing the polling and research at the Independent Center]. "If you live in a hyper-Republican or hyper-Democratic district, you should have a Democrat or Republican representing you." But with the help of AI, he identified 40 seats that don't fit that mold, where he said independents can make inroads with voters fed up with both parties. The Independent Center plans to have about 10 candidates in place by spring with the goal of winning at least half of the races. Brandon predicts those wins could prompt moderate partisans in the House to switch affiliations. Their proprietary AI tool created by an outside partner has been years in the making. While focus groups and polling have long driven understanding of American sentiments, AI can monitor what people are talking about in real time. ... They're using AI to understand core issues and concerns of voters and to hunt for districts ripe for an independent candidate to swoop in. From there, the next step is taking the data and finding what the dream candidate looks like. The Independent Center is recruiting candidates both from people who reach out to the organization directly and with the help of AI. They can even run their data through LinkedIn to identify potential candidates with certain interests and career and volunteer history. ... The AI also informs where a candidate is best placed to win. Read more of this story at Slashdot.

  • Russia Still Using Black Market Starlink Terminals On Its Drones
    by BeauHD on 02/12/2025 at 10:00 am

    schwit1 shares a report from Behind The Black: In its war with the Ukraine, it appears Russia is still managing to obtain black market Starlink mini-terminals for use on its drones, despite an effort since 2024 to block access. [Imagery from eastern Ukraine shows a Russian Molniya-type drone outfitted with a mini-Starlink terminal, reinforcing reports that Russia is improvising satellite-linked UAVs to extend their communication and operational range.] SpaceX has made no comment on this issue. According to the article, Ukraine is "exploring alternative European satellite providers in response, seeking more secure and controllable communications infrastructure for military operations." While switching to another satellite provider might allow Ukraine to shut Starlink down and prevent the Russians from using it within its territory, doing so would likely do more harm to Ukraine's military effort than Russia's. There isn't really any other service comparable at this time. And when Amazon's Leo system comes on line it will face the same black market issues. I doubt it will have any more success than SpaceX in preventing Russia from obtaining its terminals. Overall this issue is probably not a serious one militarily, however. Russia is not likely capable of obtaining enough black market terminals to make any significant difference on the battlefield. This story however highlights a positive aspect of these new constellations. Just as Russia can't be prevented from obtaining black market terminals, neither can the oppressed citizens in totalitarian nations like Russia and China be blocked as well. These constellations as designed act to defeat the censorship and information control of such nations, a very good thing. Read more of this story at Slashdot.

  • Russian Launch Site Mishap Shows Perilous State of Storied Space Program
    by BeauHD on 02/12/2025 at 7:00 am

    A Soyuz launch at Baikonur damaged Russia's only launchpad capable of sending astronauts and crucial propellant to the ISS. "The rocket itself headed to space without incident, taking three astronauts -- Sergey Kud-Sverchkov and Sergei Mikaev of Russia and Chris Williams of NASA -- to the space station," reports the New York Times. "But the force of the rocket's exhaust shoved a service platform used for prelaunch preparations out of its protective shelter. The platform fell into the flame trench below." From the report: Photos and videos of the launch site the next day showed the platform out of place and mangled. "It's heavily damaged," said Anatoly Zak, who publishes RussianSpaceWeb.com, a close tracker of Russia's space activities, "and so probably it will have to be rebuilt. Maybe some of the hardware can be reused. But it fell down, and it's destroyed." This is the latest embarrassment for the once-proud Russian space program, which the United States relied on from 2011 to 2020 to get NASA astronauts to orbit. The incident also raises questions about the future of the International Space Station if the launchpad cannot be quickly repaired. In a statement issued on Friday, Roscosmos, the state corporation in charge of the Russian space program, confirmed unspecified "damage" at the launchpad. "All necessary parts needed for repairs are at our disposal, and the damage will be dealt with in the near future," it said. Read more of this story at Slashdot.

  • Samsung Debuts Its First Trifold Phone
    by BeauHD on 02/12/2025 at 5:13 am

    At an event in Seoul on Tuesday, Samsung unveiled the Galaxy Z TriFold, a dual-hinged smartphone that unfolds into a 10-inch tablet (source paywalled; alternative source). It launches on Dec. 12 in Korea for about $2,450. The company plans to sell the phone in the U.S., but hasn't shared pricing. Bloomberg reports: Samsung's device has a different hinge design, folding inward from two sides whereas the Mate models take on a Z shape when being folded. When closed, the TriFold's outer screen offers similar dimensions to a regular smartphone. But when unfurled, it provides a tablet-style experience with a 10-inch display, larger than the panel on the Galaxy Z Fold 7. In the tablet-like mode, each of the device's screens can independently run a different app. This provides the equivalent of three separate 6.5-inch bar-style handsets side by side. Using Samsung's DeX software, which has been tweaked for this particular hardware type, you can also run a desktop-like experience directly on the large inner display. (Other Samsung phones must be plugged into an external monitor to activate DeX mode.) In DeX, the TriFold can operate as many as four distinct workspaces that can each run five apps simultaneously. To preempt concerns about potential breakage, Samsung said it has refined the phone's hinges, aluminum frame and display technology to improve long-term durability. The company will also offer a one-time 50% discount on display repair costs should one eventually be needed. At its thinnest point, the TriFold measures 3.9 millimeters (0.15 inch). Inside, it contains a 5,600 milliamp-hour battery, marking the largest capacity that Samsung has used in a folding phone so far. The battery provides as much as 17 hours of consecutive video playback with the TriFold display fully open. However, in specifications shared with Bloomberg, the company didn't say how long it expects the battery to last with typical usage. Read more of this story at Slashdot.

  • 'We Built a Database of 290,000 English Medieval Soldiers'
    by BeauHD on 02/12/2025 at 3:30 am

    An anonymous reader quotes a report from the Conversation, written by authors Adrian R. Bell, Anne Curry, and Jason Sadler: When you picture medieval warfare, you might think of epic battles and famous monarchs. But what about the everyday soldiers who actually filled the ranks? Until recently, their stories were scattered across handwritten manuscripts in Latin or French and difficult to decipher. Now, our online database makes it possible for anyone to discover who they were and how they lived, fought and travelled. To shed light on the foundations of our armed services -- one of England's oldest professions -- we launched the Medieval Soldier Database in 2009. Today, it's the largest searchable online database of medieval nominal data in the world. It contains military service records giving names of soldiers paid by the English Crown. It covers the period from 1369 to 1453 and many different war zones. We created the database to challenge assumptions about the lack of professionalism of soldiers during the hundred years war and to show what their careers were really like. In response to the high interest from historians and the public (the database has 75,000 visitors per month), the resource has recently been updated. It is now sustainably hosted by GeoData, a University of Southampton research institute. We have recently added new records, taking the dataset back to the late 1350s, meaning it now contains almost 290,000 entries. [...] We hope the database will continue to grow and go on providing answers to questions about our shared military heritage. We are sure that it will unlock many previously untold stories of soldier ancestors. Read more of this story at Slashdot.
