  • Instrument Clusters Are Now Paid Extras In Two Hyundai Models
    by BeauHD on 03/09/2026 at 7:00 am

    "Enshittification of car controls [is] rapidly accelerating," writes longtime Slashdot reader sinij, pointing to a new report from Car and Driver. From the report: Remember when iPhones used to come with free headphones and a phone charger (including the wall plug)? It didn't feel so much like Apple giving you free goodies as it did that the company was providing you with the relevant hardware to use the device. Apple stopped including headphones and charging blocks in 2020. Now, Hyundai is pulling some of its standard hardware from the box, at least for two models. Hyundai is charging customers extra for a driver's display in the new Elantra generation (more specifically, the Korea-market Avante), as well as the Ioniq 3, Motor1 reported. Both models feature Pleos Connect, Hyundai's new infotainment setup that pairs a center touchscreen with a slim 9.9-inch instrument cluster mounted above the dashboard -- except where it doesn't. In its domestic market, the instrument cluster screen is offered as a 350,000 won ($255) option for the base trim. Not the most expensive optional extra in the world, but still kind of a slap in the face for a feature traditionally viewed as standard fare. Things are more expensive for the electric Ioniq 3. In the EV's case, the base trim gives customers the full Tesla-screen experience, meaning if customers want the driver's display, they'll need to fork over the additional $5000 necessary to move up to the next-level trim. [...] Hyundai plans to have the setup equipped in 20 million cars globally by the end of the decade. Read more of this story at Slashdot.

  • Global Heating Will Hit At Least 1.8C, UN Warns, and There Are 'No Good Outcomes'
    by BeauHD on 03/09/2026 at 3:30 am

    An anonymous reader quotes a report from The Guardian: Global heating will reach at least 1.8C under even the most optimistic future, well beyond the Paris agreement goal of 1.5C, according to a UN report that warns every fraction of temperature rise intensifies destructive extreme weather, glacier melt, ecosystem loss, and island and coastal city submersion. The report by the Nairobi-based UN Environment Program confirmed overshooting the 1.5C goal inscribed in the landmark Paris agreement of 2015 was now "unavoidable" and, despite some progress in addressing the human-caused climate crisis driven by burning fossil fuels, likely in the next few years. It said: "There are no good outcomes above 1.5C." Heating of up to 3C above preindustrial levels could lead to glaciers losing more than a quarter of their mass by 2100, raising sea levels by up to 13cm. Global food production could decline by up to 14% by 2050 if there are not effective strategies to adapt. Human health, water supplies, nature, cities, infrastructure and economies could all be severely damaged. Some losses would be irreversible. Many communities may have to relocate or change their livelihoods. The report said the best hope for humanity to limit damage was to adopt an "overshoot, peak and decline" pathway that required immediate and sustained greenhouse gas emissions cuts combined with steps to remove carbon dioxide from the atmosphere. It described the goal of net zero emissions -- increasingly politically contentious in some countries -- as "an essential milestone that cannot be skipped" and stressed carbon dioxide removal through steps such as establishing vast new forests must occur alongside, not as an alternative to, deep cuts in fossil pollution. Crucially, the authors of the report, titled Limiting Overshoot, said the average global temperature could be returned to 1.5C this century only if heating stayed below about 1.8C. They warned nature's capacity to store carbon was uncertain and would shrink the more the planet heats. [...] The report's authors cited earlier work that found limiting heating to about 1.8C required global emissions to be halved by 2035. They said existing national policies were projected to lead to at least 2.3C heating, but it would still be possible to limit stay below 2C if countries delivered on net zero emissions commitments by mid-century.

  • FCC Plans Robocall Scorecard to Grade Phone Companies On Spam Call Blocking
    by BeauHD on 02/09/2026 at 11:00 pm

    The FCC is proposing (PDF) a public "robocall mitigation scorecard" that would grade phone companies on how well they block illegal spam calls while avoiding false positives on the legitimate ones. "The Scorecard will empower consumers and encourage providers to continue to combat illegal robocalls by providing the public with an assessment of the effectiveness of voice service providers' efforts to protect consumers from illegal robocalls," the FCC Consumer and Governmental Affairs Bureau said in a public notice. Ars Technica reports: The scorecards could include call-blocking statistics along with data on customer complaints and enforcement actions. The FCC said scorecards could grade providers on a number scale, with letter grades, or by classifying providers as low risk, medium risk, or high risk. The proposed tool would rate wireless, wireline, and VoIP providers on efforts to block robocalls and their "actual results in protecting [consumers] from illegal robocalls," the FCC said. "In practice, that means moving beyond a simple administrative checklist (i.e., did the provider file the right paperwork, did they offer the right tools) and toward a composite set of metrics that reflects both operational practices and measurable outcomes, including how often legitimate calls are blocked." Whether the tool is useful for consumers will depend on how it's designed, how easy each provider's scorecard is to find, and what data sources it relies on. The proposed scorecard would apply to domestic voice service providers with retail customers, but not telcos that operate solely as wholesale or intermediate providers. "Combatting the scourge of illegal robocalls remains the FCC's top consumer protection priority... As proposed in today's public notice, the FCC aims to develop a scorecard that will give consumers more information about the measures providers are taking to fight illegal robocalls, and it will also incentivize providers to improve their efforts," FCC Chairman Brendan Carr said in a press release.

  • 1Password Wades Into a Right-Wing Mess After Funding a Linux Project
    by BeauHD on 02/09/2026 at 10:00 pm

    1Password is facing customer and internal employee backlash after pledging $300,000 to support a Linux distro created by David Heinemeier Hansson, who has regularly published racist and anti-immigrant rhetoric. "The popular password manager is now a 'distinguished corporate patron' of Omacom, the nonprofit foundation that oversees a popular Linux distribution known as Omarchy," reports The Verge. From the report: One viral blog post declared that 1Password "Supports the Ethnic Cleansing of Europe" because of the donation. Others on social media asked for suggestions for alternative password managers so they would not support the funding of a project from Heinemeier Hansson, better known as DHH. The donation has also resulted in internal pushback from employees of 1Password who are disappointed by the affiliation, The Verge has learned. 1Password CEO David Faugno and cofounder Roustem Karimov have since posted internal messages addressing what Faugno describes as "concerns, both internally and externally" that have been raised "due to the polarizing nature" of DHH. DHH is a Danish entrepreneur best known for creating Ruby on Rails, Basecamp, and the Hey email client. Omarchy is DHH's "opinionated" version of Linux, meaning it's Linux the way he likes to use it. It's based on Arch Linux, with certain apps that install by default. It's also, apparently, one of 1Password's big customer environments. [...] In an internal Slack message obtained by The Verge, 1Password's Karimov downplayed the overtly racist comments from DHH, telling staff the following: "As I said, people have different personal opinions. You believe in your heart that DHH is evil, that you have the moral high ground, and that nothing will change your mind. However, not everyone believes that. It is not fair to claim a monopoly and ostracize team members who might disagree with you. There are people who are afraid to speak up simply because they will be personally attacked." 1Password CEO Faugno took a different approach, trying to reassure staff that "1Password does not endorse hateful, dehumanizing, or exclusionary views, including those shared publicly by DHH." Nonetheless, it seems the company has sacrificed a moral position for a "mission-driven" position. In the same message to staff, Faugno says "the scale and growth of [Omarchy's] use among our customers is significant -- Omarchy has grown to be the second most used Linux distribution among 1Password users." Faugno then tries to create distance, telling staff that its contribution is "to the Omacom Foundation, not an individual." Still, he says "we recognize that Omarchy is associated with DHH, its founder. Our donation is not in any way an endorsement of his personal views or conduct." Read more of this story at Slashdot.

  • CERN Transitioning From RHEL To Debian
    by BeauHD on 02/09/2026 at 9:00 pm

    Longtime Slashdot reader Microsplat: CERN plans to have all 2,200+ industrial computers and embedded systems in its accelerator-control infrastructure running Debian 13 by the end of 2026. These are systems used for accelerator control, laboratory equipment and other operational functions ... They also generate and interact with a hefty amount of data, although this Linux.com article refers more broadly to CERN's computing infrastructure. It's unclear whether the Debian migration covers all server infrastructure or what scientific-research-based systems are included. Our shops have done much the same in recent years, mostly due to CentOS and CFEngine getting the can. Phoronix adds some additional context in its article: CERN was a longtime RHEL/CentOS shop, previously co-maintained the Scientific Linux RHEL derivative, moved to CentOS in 2015, and later considered CentOS Stream. CERN says Red Hat's adoption of the "-march=x86-64-v2" compiler flag by default, which it viewed as "forced obsolescence" of older hardware, was the "straw that broke the camel's back."

  • OpenAI's Altman Says the Use of AI is 'Non-Negotiable'
    by BeauHD on 02/09/2026 at 8:00 pm

    OpenAI CEO Sam Altman said AI adoption is "non-negotiable" for countries, comparing rejecting it to refusing electricity a century ago and predicting it will unleash an unprecedented boom in entrepreneurship. "The economic growth and benefit to people that can come from this, the value to a country, is too high to ignore," he said. His comments were made during a fireside chat with U.S. Commerce Secretary Howard Lutnick at the G20 Innovation Ministerial in Chapel Hill, North Carolina. CNBC reports: Altman thinks the public won't be talking as much about AI a decade from now -- it'll be expected everywhere. "A kid growing up today will never be smarter than AI, but he or she will also never have understood a world where every product and service that they interact with is not really smart and really capable and really helpful," he said. Altman referenced the adoption of electricity multiple times in his comments and drew a line between that and AI. "I think it would be approximately as bad of an idea to say we're not going to have AI in our country as it was to say we're not going to have electricity in our country, you know, back 100 plus years ago," he said. Altman called cybersecurity one of the biggest challenges to navigate in the age of AI and one that leaders shouldn't sidestep. "I think some things are going to go very wrong with cybersecurity unless people act quite urgently," he said. Altman said that falling short in cyber defense and other areas "could set this technology back a great deal." You can watch a recording of the chat on YouTube. Read more of this story at Slashdot.
