  • Microsoft Previews Linux Containers That Run In Windows
    by BeauHD on 30/06/2026 at 6:00 pm

    Microsoft has released a public preview of Windows Subsystem for Linux (WSL) containers, adding a built-in command-line tool and API for running Linux containers directly inside Windows applications without third-party software. The update also introduces faster file access, improved networking and memory management, plus integration with Defender, Intune, and VS Code. The Register reports: WSL has always been a handy way to run Linux workloads from Windows, and is particularly convenient for Linux developers who must comply with corporate edicts to use a Windows device. The CLI for end-to-end container workflows furthers this. Microsoft stated, "WSL containers make it easier for developers and organizations to build, test, and run containerized workloads while benefiting from the security, manageability, and integration of the Windows platform." Alternatively, you could run your preferred Linux distribution natively, but that might not be an option, particularly if an organization is keen on the "security, manageability, and integration of the Windows platform." And this is an important point. WSL's existing Microsoft Defender for Endpoint (MDE) has been updated (in private preview) to be aware of Linux container events, and there are settings in Intune for managing WSL containers. Support is also in a pre-release version of VS Code, where the Docker path in the dev container settings can be changed to wslc. There is also a new default file system for WSL container that Microsoft claims makes Windows file access twice the speed. So, going from terribly slow to just slow? We'll wait until general availability is reached before passing judgment. There's a new default networking mode to improve compatibility and better memory reclaim techniques. However, none of these tweaks will be enabled by default in WSL. Microsoft wrote, "Since these changes touch mission critical paths like file system access and network, for now they are enabled just in WSL container." Read more of this story at Slashdot.

  • County With 37 Data Centers Asks Schools To 'Conserve Electricity'
    by BeauHD on 30/06/2026 at 5:02 pm

    An anonymous reader quotes a report from 404 Media: On June 26, the County Manager of Henrico County, Virginia, John Vithoulkas, sent an email to thousands of county employees asking them to help the local government conserve electricity. "Beginning July 1st, the rate we pay for electricity used in all Henrico County government and school facilities will increase dramatically -- by 25%, increasing costs by an estimated $5 million next fiscal year. We anticipate more rate increases for electricity in the years ahead," a copy of the email obtained by 404 Media said (emphasis his). Henrico County is a community of more than 350,000 people in eastern Virginia just outside of Richmond. It also hosts 37 data centers and there are plans to build 17 more, including plans to convert hundreds of acres of Civil War battlefields into data centers. Thanks to its proximity to DC and vast amounts of land, Henrico County became a data center hub seemingly overnight and its services clients big and small. Meta built a data center there in 2017. "To mitigate the impact of higher electric costs, I am asking that we, collectively, make slight adjustments to conserve electricity across our individual workspaces," Vithoulkas wrote in the email. "Turn off your lights when leaving your workspace, including when you leave for the day. Turn off your computers/laptops at the end of each workday. If your workspace has windows, adjust the blinds to manage heat from sunlight. Unplug any appliances, chargers, or other electrical items when they are not in use. Please limit use of (or refrain altogether from using) space heaters. A typical space heater alone can cost the county from $150 to $300 per year in electricity costs." "Each dollar we can save by conserving electricity is another dollar the county can reinvest into staff and the services we provide our residents," Vithoulkas email said.

  • South Korea To Spend $1 Trillion On More Memory Chip Production, Humanoid Robots
    by BeauHD on 30/06/2026 at 4:00 pm

    An anonymous reader quotes a report from Ars Technica: South Korea's government and top tech companies are committing $1 trillion to several flagship megaprojects that could bolster global memory chip supply, build new AI data centers and spur commercial deployment of humanoid robots by 2028. [...] "We must secure the core elements of AI faster than any other country," said South Korean President Lee Jae Myung in a televised speech on June 29, as reported by BBC News and other media outlets. "Semiconductors, physical AI, and AI data centers are the triple axis for a great leap forward." [...] The most costly of the megaprojects involves Samsung and SK Hynix committing $585 billion to building new chip fabrication plants in the southwest provinces of South Korea, along with boosting semiconductor fab construction in the Seoul capital region, according to Reuters. The government's goal is to double South Korea's production of dynamic random-access memory (DRAM) within five years. [...] The second flagship megaproject involves a $357 billion investment by the South Korean tech companies SK Group, GS Group, and Naver into building large-scale AI data centers in more outlying provinces, including South Chungcheong Province in the west, Gangwon Province in the east, and the North and South Jeolla Provinces in the southwest corner of South Korea. The third flagship megaproject revolves around the South Korean government assigning a "national strategic industry" designation to physical AI -- the AI systems that enable robots and self-driving vehicles to interact more autonomously with the real world. The government aims to develop a Korean "general-purpose foundation model" based on a world model to support robots within three years, according to The Chosun Daily. Hyundai Motor Company has also committed $5.8 billion to build a robot manufacturing facility and AI data center in the Saemangeum region of North Jeolla Province in the southwest, The Chosun Daily reported. The South Korean automaker has already been helping Boston Dynamics -- the US robotics company it acquired in 2021 -- use the South Korean supply chain in scaling up manufacturing to produce 30,000 Atlas humanoid robots each year by 2028. Similarly, the South Korean government announced it would aim to commercialize humanoid robots in 10 major industries by 2028, along with training 10,000 human workers as "AI robotics specialists" over the next five years, Reuters reported.

  • US Supreme Court Rules Geofence Warrants Require Constitutional Privacy Protections
    by BeauHD on 30/06/2026 at 3:00 pm

    The U.S. Supreme Court ruled 6-3 (PDF) in Chatrie v United States (No. 25-112) that geofence warrants sweeping up smartphone location data constitute searches under the Fourth Amendment. The Court found that individuals have a "reasonable expectation of privacy" in such data, even when the tracking covers only a brief period or records movements in public. "An individual has a reasonable expectation of privacy in records about his cell phone's location, and police intrude on that constitutionally protected interest when they demand the information -- even though for only a limited time, and from a third-party tech company," wrote Justice Elena Kagan. Longtime Slashdot reader schwit1 submitted the story. The Guardian reports: The use of geofence warrants is widespread, and gives law enforcement agencies the power to compel tech companies to hand over sensitive cell phone data from people at or near crime scenes. The warrants allow police and the FBI to collect this information from individuals within the radius of a virtual "fence" during a particular timeframe. But they are not restricted to requesting data for precise targets. The Chatrie case focuses on local police's pursuit of an armed bank robber in Richmond, Virginia. He fled with $195,000. Law enforcement tracked Okello Chatrie down through their use of geofence warrants. Chatrie had opted in to an optional Google "location history" feature that documented his location every few minutes. He was eventually sentenced to 12 years in prison, after pleading guilty. Chatrie's lawyers argued that this search was overly broad and violated his fourth amendment rights, which protects individuals from "unreasonable search and seizure." Lawyers said that police's use of geofence warrants amounted to an official "search" under the fourth amendment, and didn't meet the constitution's requirements for one. The government had argued that accessing only a short amount of cellphone location information means this tactic does not count as a fourth amendment search and accordingly, should not be afforded the same privacy protections. But the judges in the majority disagreed. The judges in the majority opinion also wrote that the government's characterization of generating location history as a voluntary choice is "meritless." They suggested that people aren't choosing to share private information with third parties and the government "just by doing the ordinary thing cellphone users do." "The point of carrying smartphones is to use what is on them," including the apps and services they provide -- many of which use location data to customize a user's experience, they said. [...] While the majority opinion noted that police conducted a fourth amendment search by accessing Chatrie's location history data, they noted that the court of appeals will weigh in on whether the "search was reasonable, meaning that each of its steps was properly described with particularity and found to be supported by probable cause." Law enforcement has said they need geofence warrants to find suspects and witnesses -- after reaching dead ends. The US government, for its part, has argued that people can't have a "reasonable expectation of privacy" when they are in public and have allowed a third party company, such as Google, to collect and analyze phone location data.

  • Remembering How Microsoft's Fake Windows Error Ended In a $280 Million Secret Settlement
    by EditorDavid on 30/06/2026 at 10:34 am

    Slashdot reader joshuark summarizes this walk down memory lane from the tech site MakeUseOf: Facing real competition from Digital Research's DR DOS, Microsoft secretly embedded a sabotaging mechanism known as "AARD code" into beta versions of Windows 3.1 to prevent it from running on Digital Research's competing DR DOS operating system.This code triggered fake, alarming error messages to convince developers that DR DOS was unstable... Although Microsoft disabled the feature in the final retail release, the California-based firm Caldera, Inc., which had acquired DR DOS assets, sued Microsoft for anti-competitive practices.Microsoft settled the lawsuit out of court in 2000 for $280 million, a figure that remained sealed until it was unsealed in 2009.

  • Ford Rehires 'Gray Beard' Engineers After AI Falls Short
    by EditorDavid on 30/06/2026 at 5:34 am

    Ford executives said they've hired 350 veteran engineers — some of them former employees — after AI and automated systems failed to deliver the desired quality, reports TechCrunch: Bloomberg reports the company's chief operating officer Kumar Galhotra told journalists that Ford had been "relying more and more on automated quality systems" with disappointing results. So the company "brought back technical specialists," and those specialists "hunt for failure points before a part ever reaches the plant floor." Charles Poon, Ford's vice president of vehicle hardware engineering, added, "Mistakenly we thought that by just introducing artificial intelligence and ingesting the design requirements that we had, that that would produce a high-quality product." The article points out that Ford is using the rehired gray beard engineers to train younger staff — and, to reprogram its AI tools. Read more of this story at Slashdot.
