  • Ubuntu's AI Plans Have Linux Users Looking For a 'Kill Switch'
    by BeauHD on 29/04/2026 at 10:00 pm

    Canonical's plan to add AI features to Ubuntu has sparked pushback from users who are concerned it could follow Windows 11's AI-heavy direction. "After Canonical's announcement earlier this week that it's bringing AI features to Ubuntu, replies included requests for an AI 'kill switch' or a way to disable the upcoming features," reports The Verge. Canonical says it has no plans for a "global AI kill switch" but it will allow users to remove any AI features they don't want. From the report: In his original post, [Canonical's VP of engineering, Jon Seager] said the upcoming AI features will include accessibility tools like AI speech-to-text and text-to-speech, along with agentic AI features for tasks like troubleshooting and automation. Canonical is also encouraging its engineers to use AI more and plans to begin introducing AI features in Ubuntu "throughout the next year." In a follow-up comment, Seager clarified that, "my plan is to introduce AI-backed features as a 'preview' on a strictly opt-in basis in [Ubuntu version] 26.10. In subsequent releases, my plan is to have a step in the initial setup wizard that allows the user to choose whether or not they'd like the AI-native features enabled." Ultimately, he said, "All of these capabilities will be delivered as Snaps to the OS, layered on top of the existing Ubuntu stack. That means there will always be the option of removing those Snaps." Users who prefer to avoid AI entirely could switch to other distros like Linux Mint, Pop!_OS, or Zorin OS. "These distros have some similarities to Ubuntu, but may not necessarily adopt the new AI features Canonical is rolling out," adds The Verge. Read more of this story at Slashdot.

  • Joby Demos Its Air Taxi In NYC
    by BeauHD on 29/04/2026 at 9:00 pm

    Joby Aviation has completed demonstration flights of its electric air taxi over New York City, testing real routes between JFK and Manhattan helipads as it prepares for a future commercial service. The company says its eVTOL could turn a 60- to 120-minute airport trip into a flight of under 10 minutes, though commercial launch still depends on FAA certification. Electrive reports: To launch operations in New York City, Joby acquired Blade Urban Air Mobility last year. Blade already enables helicopter flights for affluent travelers between Manhattan and airports such as JFK or Newark in just five minutes, avoiding up to two hours of traffic and typical airport hassles. Joby aims to replace this service with quiet, electric air taxis as soon as possible, transitioning Blade's existing customers to the new technology. However, introducing a new aircraft into commercial service requires a years-long certification process, overseen in the US by the Federal Aviation Administration (FAA). Joby is now in the final phase of FAA certification. Following a series of demonstration flights in the San Francisco Bay Area, the company has tested its air taxi in New York City on real flight routes and under real-world conditions. During these tests, Joby demonstrated the acoustics and performance metrics critical for entering the urban air taxi market. During these demonstration flights, Joby's air taxi took off from John F. Kennedy International Airport (JFK) and landed at various helipads across the city, including Downtown Skyport and the helipads at West 30th Street and East 34th Street in Midtown, where Blade Air Mobility's premium passenger lounges are located. These locations represent some of the commercial routes Joby plans for New York [...]. Fun fact: Joby's eVTOL aircraft are over 100 to 1,000 times quieter than a conventional helicopter, operating at roughly 55-65 dB during takeoff and landing compared to 90+ dB for helicopters.

  • Apple Gives Up On the Vision Pro After M5 Refresh Flop
    by BeauHD on 29/04/2026 at 8:00 pm

    MacRumors reports that Apple has effectively paused work on Vision Pro after the M5 refresh failed to revive demand. The team has reportedly been reassigned and the company is now shifting focus toward smart glasses instead. From the report: The Vision Pro has been criticized for its high price tag and its uncomfortable weight. The device is over 1.3 pounds, and even with the more comfortable Dual Knit Band that Apple added to redistribute weight, it continues to be hard to wear for long periods of time. The M5 chip added a 120Hz refresh rate, 10 percent more rendered pixels, and around 30 additional minutes of battery life, but the price tag stayed at $3,499, and it ended up not selling well. The Vision Pro has been unpopular since it first launched, and Apple only sold around 600,000 units in total. Insider sources told MacRumors that Apple has received an unusually high percentage of returns, far exceeding any other modern Apple product. [...] If Apple finds a way to create a much cheaper, more comfortable VR headset in the future, the Vision Pro line could be revived, but right now, the company has no plans to launch a new model. Apple has not discontinued the Vision Pro and is continuing to sell the M5 model. Instead of continuing to experiment with virtual reality, Apple is working on smart glasses that will eventually incorporate augmented reality capabilities, but the first version will be similar to the Ray-Ban Meta smart glasses with AI and no integrated display.

  • California High-Speed Rail Price Tag Jumps To $231 Billion
    by BeauHD on 29/04/2026 at 7:00 pm

    Longtime Slashdot reader schwit1 writes: California's long-delayed high-speed rail project is now facing renewed scrutiny after state leaders revealed a dramatically higher price tag, now estimated at roughly $231 billion, nearly seven times the original $33 billion projection approved by voters in 2008. The revised figures have reignited talks in Sacramento over whether the project can realistically be completed, how long it will take, and whether the state can continue to fund it at this scale. Senator Strickland pointed to comments from Lou Thompson, former chair of the California High-Speed Rail Authority peer review group, who recently criticized the latest draft business plan. Thompson wrote that the 2026 draft plan "has reached a dead end," arguing that the project has drifted far from its original vision due to escalating costs, delays, and unfunded gaps. Under current projections, assuming funding and construction proceed as planned, service between San Francisco and Bakersfield could begin around 2033, while the full Los Angeles to San Francisco connection could extend to 2040.

  • Colorado's Anti-Repair Bill Is Dead
    by BeauHD on 29/04/2026 at 6:00 pm

    An anonymous reader quotes a report from Wired: A controversial bill in Colorado that would have undone some repair protections in the state has failed. The bill had been the target of right-to-repair advocates, who saw it as a bellwether for how tech companies might try to undo repair legislation more broadly in the US. Colorado's landmark 2024 repair law, the Consumer Right to Repair Digital Electronic Equipment, went into effect in January 2026 and ensured access to tools and documentation people needed to modify and fix digital electronics such as phones, computers, and Wi-Fi routers. The new bill, SB26-090, would have carved out an exception to those repair protections for "critical infrastructure," a loosely defined term that repair advocates worried could be applied to just about any technology. SB26-090 was introduced during a Colorado Senate hearing on April 2 and was supported by lobbying efforts from companies such as Cisco and IBM. It passed that hearing unanimously. The bill then passed in the Colorado Senate on April 16. On Monday evening, the bill was discussed in a long, delayed hearing in the Colorado House's State, Civic, Military, and Veterans Affairs Committee. Dozens of supporters and detractors gave public comments. Finally, the bill was shot down in a 7-to-4 vote and classified as postponed indefinitely. "While we were making progress at chipping away at the momentum for it, we had still been losing," said Danny Katz, executive director of the local nonprofit consumer advocacy group CoPIRG. "So, we took nothing for granted, and I believe the incredible testimony from the broad range of cybersecurity experts, businesses, repair advocates, recyclers, and people who want the freedom to fix their stuff made a big difference."

  • GitHub 'No Longer a Place For Serious Work', Says Hashicorp Co-Founder
    by BeauHD on 29/04/2026 at 5:00 pm

    Hashicorp co-founder Mitchell Hashimoto says GitHub's frequent outages have made it "no longer a place for serious work," prompting him to move his Ghostty terminal emulator project elsewhere after 18 years on the platform. The Register reports: "I've been angry about it. I've hurt people's feelings. I've been lashing out. Because GitHub is failing me, every single day, and it is personal. It is irrationally personal," he wrote. The reason for his ire is the service has become unreliable. "For the past month I've kept a journal where I put an 'X' next to every date where a GitHub outage has negatively impacted my ability to work," he wrote. "Almost every day has an 'X'. On the day I am writing this post, I've been unable to do any PR review for ~2 hours because there is a GitHub Actions outage." Hashimoto penned his post a few days before an April 28 incident that saw pull requests fail to complete due to an Elasticsearch SNAFU. Incidents like that mean Hashimoto has decided GitHub "is no longer a place for serious work if it just blocks you out for hours per day, every day." "It's not a fun place for me to be anymore," he lamented. "I want to be there but it doesn't want me to be there. I want to get work done and it doesn't want me to get work done. I want to ship software and it doesn't want me to ship software." The developer says he wants GitHub to improve, but "I also want to code. And I can't code with GitHub anymore. I'm sorry. After 18 years, I've got to go." He's open to a return if GitHub can deliver "real results and improvements, not words and promises." But for now, he's working to move Ghostty to another collaborative code locker. "We have a plan but I'm also very much still in discussions with multiple providers (both commercial and FOSS)," Hashimoto wrote. "It'll take us time to remove all of our dependencies on GitHub and we have a plan in place to do it as incrementally as possible." He's doing the equivalent of leaving a toothbrush at a former partner's house by leaving a read-only mirror of Ghostty on GitHub, and by keeping his personal projects on the Microsoft-owned service. But Hashimoto's moving his day job somewhere new. "Ghostty is where I, our maintainers, and our open source community are most impacted so that is the focus of this change. We'll see where it goes after that," he concluded. Read more of this story at Slashdot.
