  • Hydropower Line From Quebec Could Power a Million NYC Homes
    by BeauHD on 17/03/2026 at 7:00 am

    The Champlain Hudson Power Express, a $6 billion, 339-mile buried transmission line, will soon deliver Canadian hydropower from Hydro-Quebec to New York City. The project could supply up to 20% of the city's electricity and power roughly one million homes throughout the year. "This is far and away the largest project I have ever worked on," said Bob Harrison, who has worked in infrastructure for 40 years and is the head of engineering for the Champlain Hudson Power Express. "We like to say it's the largest project you'll never see." The New York Times reports: The massive power project, expected to provide energy to a million New York City customers a year, travels underground and underwater, from the northern plains at the Canadian border to the filled-in marshlands of coastal Queens, much of it loosely following the Hudson River. Its construction included the underwater installation of more than two million feet of cable imported from Sweden. It also required special boats, loaded with equipment that could shoot water jets deep into the sediment, to create trenches for the cable. Then, when it came to placing cable beneath the landscape, more than 700 land-use easements were needed, plus an additional 1.55 million feet of cable. The Champlain Hudson Power Express has found a way to plug into the city, but it wasn't easy. The work included 10 new manholes and more than three miles of new underground circuitry, according to Con Edison, the city's primary electricity provider. "It was literally a hand weave under the streets of Queens," said Jennifer Laird-White, the head of external affairs for Transmission Developers. The hydropower travels from Canada via two buried cables that are as round as cantaloupes. Those lines snake for hundreds of miles under a lake, several rivers (including the Hudson for about 90 miles) and through buried trenches alongside train tracks and roads. The cables resurface in Astoria, Queens, where a converter station shapes, filters and refines the raw power into a product that New Yorkers can consume. In two cavernous rooms that could be mistaken for "Star Wars" sets, the electricity flows through 30 hanging structures encased in what look like metallic, dinosaurlike exoskeletons. Each one weighs about as much as a small humpback whale and contains microprocessors, thousands of valves and fiber wires. "I am still wowed when I walk into that facility," said Mr. Harrison, the engineer. "I mean, it is just mind-boggling." Read more of this story at Slashdot.

  • New 'Vibe Coded' AI Translation Tool Splits the Video Game Preservation Community
    by BeauHD on 17/03/2026 at 3:30 am

    An anonymous reader quotes a report from Ars Technica: Since Andrej Karpathy coined the term "vibe coding" just over a year ago, we've seen a rapid increase in both the capabilities and popularity of using AI models to throw together quick programming projects with less human time and effort than ever before. One such vibe-coded project, Gaming Alexandria Researcher, launched over the weekend as what coder Dustin Hubbard called an effort to help organize the hundreds of scanned Japanese gaming magazines he's helped maintain at clearinghouse Gaming Alexandria over the years, alongside machine translations of their OCR text. A day after that project went public, though, Hubbard was issuing an apology to many members of the Gaming Alexandria community who loudly objected to the use of Patreon funds for an error-prone AI-powered translation effort. The hubbub highlights just how controversial AI tools remain for many online communities, even as many see them as ways to maximize limited funds and man-hours. "I sincerely apologize," Hubbard wrote in his apology post. "My entire preservation philosophy has been to get people access to things we've never had access to before. I felt this project was a good step towards that, but I should have taken more into consideration the issues with AI." "I'm very, very disappointed to see [Gaming Alexandria], one of the foremost organizations for preserving game history, promoting the use of AI translation and using Patreon funds to pay for AI licenses," game designer and Legend of Zelda historian Max Nichols wrote in a post on Bluesky over the weekend. "I have cancelled my Patreon membership and will no longer promote the organization." Nichols later deleted his original message (archived here), saying he was "uncomfortable with the scale of reposts and anger" it had generated in the community. However, he maintained his core criticism: that Gemini-generated translations inevitably introduce inaccuracies that make them unreliable for scholarly use. In a follow-up, he also objected to Patreon funds being used to pay for AI tools that produce what he called "untrustworthy" translations, arguing they distort history and are not valid sources for research. "... It's worthless and destructive: these translations are like looking at history through a clownhouse mirror," he added. Read more of this story at Slashdot.

  • 'Pokemon Go' Players Unknowingly Trained Delivery Robots With 30 Billion Images
    by BeauHD on 16/03/2026 at 11:00 pm

    More than 30 billion images captured by Pokemon Go players have helped train a visual mapping system developed by Niantic. The technology is now being used to guide delivery robots from Coco Robotics through city streets where GPS often struggles. Popular Science reports: This week, Niantic Spatial, part of the team behind Pokemon Go, announced a partnership with Coco Robotics, a company that makes short-distance delivery robots for food and groceries. Soon, those robot couriers will scoot around sidewalks using Niantic's Visual Positioning System (VPS)-- a navigation tool that can reportedly pinpoint location down to a few centimeters just by looking at nearby buildings and landmarks. Niantic trained that VPS model on more than 30 billion images captured by Pokemon Go users, and claims it will help robots operate in areas where GPS falls short. [...] Instead of helping users navigate the way that GPS does, VPS determines where someone is based on their surroundings. That makes Pokemon Go particularly useful as a data source, because players had to physically travel to specific locations and point their phones at various angles. That mapping effort got a significant boost in 2020, when the app added what it called "Field Research," a feature prompting players to scan real-world statues and landmarks with their cameras in exchange for in-game rewards. A portion of the data also reportedly came from areas known as "Pokemon battle arenas." Whether players knew it or not, those scans were creating 3D models of the real world that would eventually power the Niantic model. More data means better accuracy, and because Niantic was collecting images of the same locations from many different users, it could capture the same spots across varying weather conditions, lighting, angles, and heights. [...] The idea is that Coco's robots can use VPS and four cameras mounted around the machine to get a far more precise read on their surroundings. In turn, the well-equipped robot will deliver food on time. On a broader level, Niantic says its partnership with Coco Robotics is part of a longer-term effort to build a "living map" of the world that updates as new data becomes available. Once VPS-equipped delivery robots hit the streets, they will collect even more info that can be fed back into the model to bolster its accuracy further. This kind of continuous, real-world data collection is already central to how self-driving vehicle companies like Waymo and Tesla operate, and is a large part of why that technology has improved so significantly in recent years.

  • Nvidia Bets On OpenClaw, But Adds a Security Layer Via NemoClaw
    by BeauHD on 16/03/2026 at 10:00 pm

    During today's Nvidia GTC keynote, the company introduced NemoClaw, a security-focused stack designed to make the autonomous AI agent platform OpenClaw safer. ZDNet explains how it works: NemoClaw installs Nvidia's OpenShell, a new open-source runtime that keeps agents safer to use by enforcing an organization's policy-based guardrails. OpenShell keeps models sandboxed, adds data privacy protections and additional security for agents, and makes them more scalable. "This provides the missing infrastructure layer beneath claws to give them the access they need to be productive, while enforcing policy-based security, network, and privacy guardrails," Nvidia said in the announcement. The company built OpenShell with security companies like CrowdStrike, Cisco, and Microsoft Security to ensure it is compatible with other cybersecurity tools. Nvidia said NemoClaw can be installed in a single command, runs on any platform, and can use any coding agent, including Nvidia's own Nemotron open model family, on a local system. Through a privacy router, it allows agents to access frontier models in the cloud, which unites local and cloud models to help teach agents how to complete tasks within privacy guardrails, Nvidia explained. Nvidia seems to be hoping that the additional security can make OpenClaw agents more popular and accessible, with less risk than they currently carry. The bigger picture here is how NemoClaw could give companies the added peace of mind to let AI agents complete actions for their employees, where they wouldn't have previously. Nvidia did not specify when NemoClaw would be available. Read more of this story at Slashdot.

  • Polymarket Gamblers Threaten To Kill Journalist Over Iran Missile Story
    by BeauHD on 16/03/2026 at 9:00 pm

    An anonymous reader quotes a report from the Times of Israel, written by journalist Emanuel Fabian: On Tuesday, March 10, a massive explosion shook the city of Beit Shemesh, just outside Jerusalem, in yet another Iranian ballistic missile attack during the ongoing war. Rescue services scrambled to the scene in search of possible casualties, though as it turned out, the projectile had struck a forested area just outside the city, around 500 meters from homes. On The Times of Israel's liveblog that day, I reported that the missile had hit an open area and no injuries were caused, citing the rescue services, as well as footage that emerged showing the massive explosion caused by the missile's warhead. But what I thought was a seemingly minor incident during the war has turned into days of harassment and death threats against me. Emanuel began receiving numerous emails, messages and phone calls from individuals urging him to change the report to say the missile had been intercepted. "It was indeed a little strange to receive the same question, about something relatively inconsequential, from two different people within a day," he said. The connection eventually became clear after he noticed two users on X responding to his story with apparent ties to Polymarket. "There are people saying that they have received word from you that the missile strike in Beit Shemesh on March 10th was in fact intercepted, is this true or did no such interaction occur?" one user wrote. Another asked, "Was there any video of the actual impact?" The rules of this particular Polymarket bet state: "This market will resolve to 'Yes' if Iran initiates a drone, missile, or air strike on Israel's soil on the listed date in Israel Time (GMT+2). Otherwise, this market will resolve to 'No'." However, there is a clause: "Missiles or drones that are intercepted... will not be sufficient for a 'Yes' resolution, regardless of whether they land on Israeli territory or cause damage." At that point, Emanuel realized his "minor report" of a missile strike had suddenly become part of a "betting war," with traders who had wagered 'No' on an Iranian strike on Israel on March 10 pressuring him to change the article so they could win their bets. When he refused, some of the Polymarket gamblers escalated to harassment, fabricated messages, bribery attempts, and explicit threats against him and his family. "You have no idea how much you've put yourself at risk," wrote a user named Haim. "Today is the most significant day of your career. You have two choices: either believe that we have the capabilities, and after you make us lose $900,000 we will invest no less than that to finish you. Or end this with money in your pocket, and also earn back the life you had until now." After receiving no response, Haim sent him another series of messages: "You are choosing to go to war knowing that you will lose your life as you've grown accustomed to it -- for nothing." He later added: "You have exactly a few hours left to fix your attempt at influencing [the market]. It would be stupid of you to ignore this." According to Emanuel, the messages also included detailed threats referencing his neighborhood, parents, and family. Read more of this story at Slashdot.

  • Encyclopedia Britannica Sues OpenAI For Copyright, Trademark Infringement
    by BeauHD on 16/03/2026 at 8:00 pm

    Encyclopedia Britannica has sued OpenAI, alleging its AI models were trained on nearly 100,000 copyrighted articles and sometimes reproduce or misattribute passages to the encyclopedia. The lawsuit also claims trademark infringement and argues tools like ChatGPT divert traffic away from Britannica and Merriam-Webster sites. Engadget reports: More specifically, Britannica alleged that OpenAI illegally used its "copyrighted content at a massive scale" when training its AI models. Not just with training, the encyclopedia company claimed that ChatGPT's responses to user queries sometimes contain "full or partial verbatim reproductions of [Britannica's] copyright articles." Along with claims of copyright violations, Britannica argued that OpenAI was also responsible for trademark infringement. According to the lawsuit, ChatGPT generates "made-up content or 'hallucinations' and falsely attributes them" to Encyclopedia Britannica. The lawsuit doesn't specify an amount for monetary damages, but Britannica is also seeking an injunction to prevent OpenAI from repeating these accusations. Read more of this story at Slashdot.
