  • 'Food and Fossil Fuel Production Causing $5 Billion of Environmental Damage an Hour'
    by BeauHD on 10/12/2025 at 3:30 am

    An anonymous reader quotes a report from the Guardian: The unsustainable production of food and fossil fuels causes $5 billion of environmental damage per hour, according to a major UN report. Ending this harm was a key part of the global transformation of governance, economics and finance required "before collapse becomes inevitable," the experts said. The Global Environment Outlook (GEO) report, which is produced by 200 researchers for the UN Environment Program, said the climate crisis, destruction of nature and pollution could no longer be seen as simply environmental crises. "They are all undermining our economy, food security, water security, human health and they are also [national] security issues, leading to conflict in many parts of the world," said Prof Robert Watson, the co-chair of the assessment. [...] The GEO report is comprehensive -- 1,100 pages this year -- and is usually accompanied by a summary for policymakers, which is agreed by all the world's countries. However, strong objections by countries including Saudi Arabia, Iran, Russia, Turkey and Argentina to references to fossil fuels, plastics, reduced meat in diets and other issues meant no agreement was reached this time. [...] The GEO report emphasized that the costs of action were much less than the costs of inaction in the long term, and estimated the benefits from climate action alone would be worth $20 trillion a year by 2070 and $100 trillion by 2100. "We need visionary countries and private sector [companies] to recognize they will make more profit by addressing these issues rather than ignoring them," Watson said. [...] One of the biggest issues was the $45 trillion a year in environmental damage caused by the burning of coal, oil and gas, and the pollution and destruction of nature caused by industrial agriculture, the report said. The food system carried the largest costs, at $20 trillion, with transport at $13 trillion and fossil-fuel powered electricity at $12 trillion. These costs -- called externalities by economists -- must be priced into energy and food to reflect their real price and shift consumers towards greener choices, Watson said: "So we need social safety nets. We need to make sure that the poorest in society are not harmed by an increase in costs." The report suggests measures such as a universal basic income, taxes on meat and subsidies for healthy, plant-based foods. There were also about $1.5 trillion in environmentally harmful subsidies to fossil fuels, food and mining, the report said. These needed to be removed or repurposed, it added. Watson noted that wind and solar energy was cheaper in many places but held back by vested interests in fossil fuel. The climate crisis may be even worse than thought, he said: "We are likely to be underestimating the magnitude of climate change," with global heating probably at the high end of the projections made by the Intergovernmental Panel on Climate Change. Removing fossil fuel subsidies could cut emissions by a third, the report said. Read more of this story at Slashdot.

  • OpenAI Joins the Linux Foundation's New Agentic AI Foundation
    by BeauHD on 10/12/2025 at 2:02 am

    OpenAI, alongside Anthropic and Block, have launched the Agentic AI Foundation under the Linux Foundation, describing it as a neutral home for standards as agentic systems move into real production. It may sound well-meaning, but Slashdot reader and NERDS.xyz founder BrianFagioli isn't buying the narrative. In a report for NERDS.xyz, Fagioli writes: Instead of opening models, training data, or anything that would meaningfully shift power toward the community, the companies involved are donating lightweight artifacts like AGENTS.md, MCP, and goose. They're useful, but they're also the safest, least threatening pieces of their ecosystem to "open." From where I sit, it looks like a strategic attempt to lock in influence over emerging standards before truly open projects get a chance to define the space. I see the entire move as smoke and mirrors. With regulators paying closer attention and developer trust slipping, creating a Linux Foundation directed fund gives these companies convenient cover to say they're being transparent and collaborative. But nothing about this structure forces them to share anything substantial, and nothing about it changes the closed nature of their core technology. To me, it looks like Big Tech trying to set the rules of the game early, using the language of openness without actually embracing it. Slashdot readers have seen this pattern before, and this one feels no different. Read more of this story at Slashdot.

  • Netflix Faces Consumer Class Action Over $72 Billion Warner Bros Deal
    by BeauHD on 10/12/2025 at 1:25 am

    Netflix's $72 billion bid to buy Warner Bros Discovery has triggered a consumer class action claiming the merger would crush competition, erase HBO Max as a rival, and hand Netflix control over major franchises. Reuters reports: The proposed class action (PDF) was filed on Monday by a subscriber to Warner Bros-owned HBO Max who said the proposed deal threatened to reduce competition in the U.S. subscription video-on-demand market. "Netflix has demonstrated repeated willingness to raise subscription prices even while facing competition from full-scale rivals such as WBD," the lawsuit said. [...] The lawsuit said the Warner Bros deal would eliminate one of Netflix's closest rivals, HBO Max, and give Netflix control over Warner Bros marquee franchises including Harry Potter, DC Comics and Game of Thrones. On Monday, Paramount Skydance launched a $108 billion hostile bid to buy Warner Bros. Discovery with an all-cash, $30-per-share offer. Read more of this story at Slashdot.

  • Ask Slashdot: What Are the Best Locally-Hosted Wireless Security Cameras?
    by BeauHD on 10/12/2025 at 12:45 am

    Longtime Slashdot reader Randseed writes: With the likes of Google Nest, Ring, and others cooperating with law enforcement, I started to look for affordable wireless IP security cameras that I can put around my house. Unfortunately, it looks like almost every thing now incorporates some kind of cloud-based slop. All I really want is to put up some cameras, hook them up to my LAN, and install something like ZoneMinder. What are the most economical, wireless IP security cameras that I can set up with my server? Read more of this story at Slashdot.

  • More People Crowdfunded Basic Needs In 2025, GoFundMe Report Shows
    by BeauHD on 10/12/2025 at 12:02 am

    An anonymous reader quotes a report from Fast Company: More and more people are turning to GoFundMe for help covering the cost of housing, food, and other basic needs. The for-profit crowdfunding platform's annual "Year in Help" report, released Tuesday, underscored ongoing concerns around affordability. The number of fundraisers started to help cover essential expenses such as rent, utilities, and groceries jumped 20%, according to the company's 2025 review, after already quadrupling last year. "Monthly bills" were the second fastest-growing category behind individual support for nonprofits. The number of "essentials" fundraisers has increased over the last three years in all of the company's major English-speaking markets, according to GoFundMe CEO Tim Cadogan. That includes the United States, Canada, United Kingdom and Australia. In the United States, the self-published report comes at the end of a year that has seen weakened wage growth for lower-income workers, sluggish hiring, a rise in the unemployment rate and low consumer confidence in the economy. [...] Among campaigns aimed at addressing broader community needs, food banks were the most common recipient on GoFundMe this year. The platform experienced a nearly sixfold spike in food-related fundraisers between the end of October and first weeks of November, according to Cadogan, as many Americans' monthly SNAP benefits got suddenly cut off during the government shutdown.

  • Congress Quietly Strips Right-To-Repair Provisions From US Military Spending Bill
    by BeauHD on 09/12/2025 at 11:20 pm

    Congress quietly removed provisions that would have let the U.S. military fix its own equipment without relying on contractors, despite bipartisan and Pentagon support. The Register reports: The House and Senate versions of the NDAA passed earlier both included provisions that would have extended common right-to-repair rules to US military branches, requiring defense contractors to provide access to technical data, information, and components that enabled military customers to quickly repair essential equipment. Both of those provisions were stripped from the final joint-chamber reconciled version of the bill, published Monday, right-to-repair advocates at the US Public Interest Research Group (PIRG) pointed out in a press release. [...] According to PIRG's press release on the matter, elected officials have been targeted by an "intensive lobbying push" in recent weeks against the provisions. House Armed Services Committee chair Mike Rogers (R-AL) and ranking Democrat Adam Smith (D-WA), responsible for much of the final version of the bill, have received significant contributions from defense contractors in recent years, and while correlation doesn't equal causation, it sure looks fishy. [Isaac Bowers, PIRG's federal legislative director] did tell us that he was glad that the defense sector's preferred solution to the military right to repair fight -- a "data as a service" solution -- was also excluded, so the 2026 NDAA isn't a total loss for the repairability fight. "That provision would have mandated the Pentagon access repair data through separate vendor contracts rather than receiving it upfront at the time of procurement, maintaining the defense industry's near monopoly over essential repair information and keeping troops waiting for repairs they could do quicker and cheaper themselves," Bowers said in an email. An aide to the Democratic side of the Committee told The Register the House and Senate committees did negotiate a degree of right-to-repair permissions in the NDAA. According to the aide and a review of the final version of the bill, measures were included that require the Defense Department to identify any instances where a lack of technical data hinders operation or maintenance of weapon systems, as well as aviation systems. The bill also includes a provision that would establish a "technical data system" that would "track, manage, and enable the assessment" of data related to system maintenance and repair. Unfortunately, the technical data system portion of the NDAA mentions "authorized repair contractors" as the parties carrying out repair work, and there's also no mention of parts availability or other repairability provisions in the sections the staffer flagged -- just access to technical data. That means the provisions are unlikely to move the armed forces toward a new repairability paradigm. Read more of this story at Slashdot.
