  • Kernel Community Drafts a Plan For Replacing Linus Torvalds
    by BeauHD on 29/01/2026 at 1:25 am

    The Linux kernel community has formalized a continuity plan for the day Linus Torvalds eventually steps aside, defining how the process would work to replace him as the top-level maintainer. ZDNet's Steven Vaughan-Nichols reports: The new "plan for a plan," drafted by longtime kernel contributor Dan Williams, was discussed at the latest Linux Kernel Maintainer Summit in Tokyo, where he introduced it as "an uplifting subject tied to our eventual march toward death." Torvalds added, in our conversation, that "part of the reason it came up this time around was that my previous contract with Linux Foundation ended Q3 last year, and people on the Linux Foundation Technical Advisory Board had been aware of that. Of course, they were also aware that we'd renewed the contract, but it meant that it had been discussed." The plan stops short of naming a single heir. Instead, it creates an explicit process for selecting one or more maintainers to take over the top-level Linux repository in a worst-case or orderly-transition scenario, including convening a conclave to weigh options and maximize long-term project health. One maintainer in Tokyo jokingly suggested that the group, like the conclave that selects a new pope, be locked in a room and that a puff of white smoke be sent out when a decision was reached. The document frames this as a way to protect against the classic "bus factor" problem. That is, what happens to a project if its leader is hit by a bus? Torvalds' central role today means the project currently assumes a bus-factor of one, where a single person's exit could, in theory, destabilize merges and final releases. In practice, as Torvalds and other top maintainers have discussed, the job of top penguin would almost certainly currently go to Greg Kroah-Hartman, the stable-branch Linux kernel maintainer. Responding to the suggestion that the backup replacement would be Greg KH, Torvalds said: "But the thing is, Greg hasn't always been Greg. Before Greg, there was Andrew Morton and Alan Cox. After Greg, there will be Shannon and Steve. The real issue is you have to have a person or a group of people that the development community can trust, and part of trust is fundamentally about having been around for long enough that people know how you work, but long enough does not mean to be 30 years."

  • French Lawmakers Vote To Ban Social Media Use By Under-15s
    by BeauHD on 29/01/2026 at 12:45 am

    French lawmakers have voted to ban social media access for children under 15 and prohibit mobile phones in high schools, positioning France as the second country after Australia to impose sweeping age-based digital restrictions. The Guardian reports: The lower national assembly adopted the text by a vote of 130 to 21 in a lengthy overnight session from Monday to Tuesday. It will now go to the Senate, France's upper house, ahead of becoming law. Macron hailed the vote as a "major step" to protect French children and teenagers in a post on X. The legislation, which also provides for a ban on mobile phones in high schools, would make France the second country to take such a step following Australia's ban for under-16s in December. [...] "The emotions of our children and teenagers are not for sale or to be manipulated, either by American platforms or Chinese algorithms," Macron said in a video broadcast on Saturday. Authorities want the measures to be enforced from the start of the 2026 school year for new accounts. Former prime minister Gabriel Attal, who leads Macron's Renaissance party in the lower house, said he hoped the Senate would pass the bill by mid-February so that the ban could come into force on September 1. He added that "social media platforms will then have until December 31 to deactivate existing accounts" that do not comply with the age limit. [...] The draft bill excludes online encyclopedias and educational platforms. An effective age verification system would have to come into force for the ban to become reality. Work on such a system is under way at the European level. Read more of this story at Slashdot.

  • Software Company Bonds Drop As Investors' AI Worries Mount
    by BeauHD on 29/01/2026 at 12:02 am

    An anonymous reader quotes a report from Bloomberg: Investors are souring on the bonds of software companies that service industries ranging from automotive to finance as fast-paced artificial intelligence innovations threaten to upend their business models. [...] Bond prices tumbled as advances in artificial intelligence rack up. Google announced plans to launch an AI assistant to browse for internet surfers Wednesday while a customer support startup, Decagon AI Inc., raised a new round of funding. Such developments are further stoking the angst about AI displacing enterprise software companies, driving a selloff in the sector's stocks and bonds across the globe. [...] Some say the AI fears weighing on software companies are overdone. "While point-solution software faces disruption risk, large company platforms with complex workflows and proprietary data are better positioned to benefit from AI-driven automation," wrote Union Bancaire Prive in its investment outlook for 2026 released this week. But a recent report by EY-Parthenon flagged that in the UK last year, software and computer services firms issued the highest number of warnings on earnings among listed firms. "Software multiples have compressed amid uncertainty around whether incumbents can defend pricing power and sustain growth in an AI-first work-flow environment," wrote Bruce Richards, chief executive officer and chairman of Marathon Asset Management, in a LinkedIn post last week.

  • Apple Tells Patreon To Move Creators To In-App Purchase For Subscriptions
    by BeauHD on 28/01/2026 at 11:20 pm

    Apple is forcing Patreon to move all remaining creators onto Apple's in-app purchase subscription system by November 2026 "or else Patreon would risk removal from the App Store," reports TechCrunch. "Apple made this decision because Patreon was managing the billing for some percentage of creators' subscriptions, and the tech giant saw that as skirting its App Store commission structure." The tech giant initially told Patreon that it must do so by November 2025, but the deadline was pushed back. From the report: "We strongly disagree with this decision," its blog post states. "Creators need consistency and clarity in order to build healthy, long-term businesses. Instead, creators using legacy billing will now have to endure the whiplash of another policy reversal -- the third such change from Apple in the past 18 months. Over the years, we have proposed multiple tools and features to Apple that we could've built to allow creators using legacy billing to transition on their own timelines, with more support added in. Unfortunately, Apple has continually declined them," it says. Creators can read more about the transition plan on Patreon's website. It has also built several tools to support these changes, including a benefit eligibility tool to see who has paid or is scheduled to pay, tier repricing tools, and gifting and discount tools to offer payment flexibility. An option for annual-only memberships will be introduced before November 2026 as well. The commission on in-app purchases and subscriptions is 30% on Apple's system, but "drops to 15% for a subscription that has been ongoing for more than a year," notes MacRumors. Patreon lets creators either raise prices only in its iOS app to cover Apple's fee or keep prices the same by absorbing the cost, while iPhone and iPad users can avoid the App Store commission entirely by paying through Patreon's website instead.

  • Google Says AI Agent Can Now Browse on Users' Behalf
    by BeauHD on 28/01/2026 at 10:40 pm

    Google is rolling out an "auto browse" AI agent in Chrome that can navigate websites, fill out forms, compare prices, and handle tedious online tasks on a user's behalf. Bloomberg reports: The feature, called auto browse, will allow users to ask an assistant powered by Gemini to complete tasks such as shopping for them without leaving Chrome, said Charmaine D'Silva, a director of product. Chrome users will be able to plan a family trip by asking Gemini to open different airline and hotel websites to compare prices, for instance, D'Silva explained. "Our testers have used it for all sorts of things: scheduling appointments, filling out tedious online forms, collecting their tax documents, getting quotes for plumbers and electricians, checking if their bills are paid, filing expense reports, managing their subscriptions, and speeding up renewing their driving licenses -- a ton of time saved," said Parisa Tabriz, vice president of Chrome, in a blog post. [...] Chrome's auto browse will be available to US AI pro and AI Ultra subscribers and will use Google Password Manager to sign into websites on a user's behalf. As part of the launch, Google is also bringing its image generation tool, Nano Banana, directly into Chrome. The company said that safeguards have been placed to ensure the agentic AI will not be able to make final calls, such as placing an order, without the user's permission. "We're using AI as well as on-device models to protect people from what's really an ever-evolving landscape, whether it's AI-generated scams or just increasingly sophisticated attackers," Tabiz said during the call.

  • US Cyber Defense Chief Uploaded Sensitive Files Into a Public Version of ChatGPT
    by BeauHD on 28/01/2026 at 10:02 pm

    An anonymous reader quotes a report from Politico: The interim head of the country's cyber defense agency uploaded sensitive contracting documents into a public version of ChatGPT last summer, triggering multiple automated security warnings that are meant to stop the theft or unintentional disclosure of government material from federal networks, according to four Department of Homeland Security officials with knowledge of the incident. The apparent misstep from Madhu Gottumukkala was especially noteworthy because the acting director of the Cybersecurity and Infrastructure Security Agency had requested special permission from CISA's Office of the Chief Information Officer to use the popular AI tool soon after arriving at the agency this May, three of the officials said. The app was blocked for other DHS employees at the time. None of the files Gottumukkala plugged into ChatGPT were classified, according to the four officials, each of whom was granted anonymity for fear of retribution. But the material included CISA contracting documents (PDF) marked "for official use only," a government designation for information that is considered sensitive and not for public release. Cybersecurity sensors at CISA flagged the uploads this past August, said the four officials. One official specified there were multiple such warnings in the first week of August alone. Senior officials at DHS subsequently led an internal review to assess if there had been any harm to government security from the exposures, according to two of the four officials. It is not clear what the review concluded. Read more of this story at Slashdot.
