Denmark Gives Up On Replacing Microsoft Office With Collabora (tomshardware.com) 2

Denmark's Ministry of Digitization reportedly abandoned a pilot to replace Microsoft Office with the open-source Collabora suite less than six months after it began. Tom's Hardware reports: According to Danish publication Computerworld, the pilot project was launched in 2025 and involved 38 employees, all of whom would start using the British open-source Collabora office suite instead of Word, PowerPoint, and Excel. The experiment was initiated by the then Digitization Minister Caroline Stage, who wanted to reduce the country's dependence on American technology. Denmark isn't alone in moving away from U.S. software, with France and the Netherlands both taking steps to replace Microsoft Windows. However, it seemed that the experiment fizzled out less than six months after it started. It had reportedly ended by the time the Danish government called for an early election in February 2026, with some employees complaining about issues with style, paragraph formatting, blank pages, and challenges with tracking changes.

But even though it's been months since the experiment reportedly ended, Prof. Mikkel Flyberbom of the Copenhagen Business School complains that the project hasn't been properly evaluated. "It's a good idea to test alternatives in a pilot project," the professor said in an email. "However, I wish that the ministry would take the opportunity to learn from the pilot project and share those experiences with other parts of the public sector."

US Designates Helium As a Critical Material (apnews.com) 33

An anonymous reader quotes a report from the Associated Press: The U.S. designated helium as a critical material on Friday because it's indispensable for making semiconductors that are essential to energy generation, and the global supply is at risk of disruption, according to the Energy Department. The designation by the Energy Department means that more federal financing will be available for helium producers and that the government will monitor it more closely. Helium is primarily produced as a byproduct of natural gas processing. The United States is the world's largest producer of natural gas and of helium. Qatar and Russia are the other top helium producers.

[...] Helium makes balloons rise, but that's not why the DOE is interested in it. Helium plays an important role in wind, solar and nuclear energy production, space exploration, medical imaging and research. Assistant Secretary of Energy Audrey Robertson said helium's unique properties make it irreplaceable, such as the fact that it's non-combustible and has the lowest boiling point of any gas. The nation needs an ample supply for semiconductors, quantum and super computing, and superconducting magnets, added Robertson, who oversees the Office of Critical Minerals and Energy Innovation.

[...] Despite environmental concerns with recovering helium from natural gas, there are also opportunities, said Greeshma Gadikota, director of the Lenfast Center for Sustainable Energy at Columbia University. "If we burn the natural gas, there are a lot of CO2 emissions associated with that," Gadikota said. "But if you just extract the helium and use it, the uses of it don't contribute necessarily to greenhouse gas emissions. "So from a climate standpoint, if we are going to continue down the line of extracting natural gas and recovering helium," she added, "I would prefer to see natural gas being used in a form where we directly produce hydrogen and we produce solid carbon." Hydrogen is a clean burning fuel, and solid carbon can provide permanent carbon sequestration and can be used widely in industrial applications, including rubber and pigments.

Firefox Tries to Bring Back the Internet's 'Good Old Days' 91

Mozilla launched a new ad campaign for Firefox that leverages early internet nostalgia in a bid to win back users who switched browsers. "Today's internet tracks you, interrupts you, and asks for permissions it already took. But it wasn't always that way, and it's not how it's supposed to work," writes Mozilla CEO Anthony Enzor-DeMeo in a post on LinkedIn. "It's how a few companies decided it should work, because it pays."

"We're making a different bet at Firefox. Remember us? Well, we're still here, and we don't think the internet should be like this..." The ad features viral internet stars from yesteryear, including Tay Zonday of "Chocolate Rain" fame, Gary Brolsma of "Numa Numa", Noah Ritter, better known as the "Apparently Kid", and Laina Morris, the face of the "Overly Attached Girlfriend" meme, among others.

Instagram Chases YouTube With a Push For Longer, Widescreen Videos (theverge.com) 36

Instagram is testing a new longform, horizontal video format called "Features" as it pushes further into YouTube territory and expands its presence on TVs. The Verge reports: Instagram boss Adam Mosseri has been against doing longform video on the platform "for a long time," he says in a six-and-a-half-minute video (here's the widescreen version) with VP of product Tessa Lyons, saying that "one of my concerns has been, how do we make sure that we keep Instagram not just about entertainment, but about connecting with friends." If you watch a longform video, "it's a lot of Reels, photos, and carousels that you might not have sent to a friend," meaning less likes and shares. Now, though, the team is working on making shortform and longform video "symbiotic," according to Mosseri, like podcasts or comedy specials that can be both long videos and broken up into shorter ones.

The announcement of this widescreen video push also follows the launch of Instagram's TV app late last year. That app launched first as a Reels-focused experience and as a pilot for Amazon Fire TV devices in the US, but it's since expanded to Google TVs, Samsung TVs and Apple TV, and Instagram launched new features like the ability to watch Stories earlier this year.

Amazon Deforestation Fell To Lowest Level Since 1988 - And Silva Wins Reelection (yahoo.com) 65

Brazil's 80-year-old president Luiz Inácio Lula da Silva was re-elected Sunday, reports the Guardian, "defeating his far-right opponent, Flávio Bolsonaro, to claim a historic fourth term in power."

And the results could impact the climate, suggests the Associated Press, since under da Silva the annual deforestation rate in the Amazon fell to its lowest level since records began in 1988: Official satellite data showed the rainforest lost 3,335 square kilometers (1,300 square miles) from Aug. 2025 through July 2026, the period used to calculate the annual rate...

During Jair Bolsonaro's presidency, from 2019 to 2022, Amazon deforestation surged by about 60%, with more than 45,000 square kilometers (17,400 square miles) cleared, according to official data. Under Lula, deforestation has fallen 71% since 2023, the government said. One of Lula's first moves after taking office in January 2023 for a third, non-consecutive term was to revive the Action Plan for the Prevention and Control of Deforestation in the Legal Amazon, known by its Portuguese acronym, PPCDAm. Launched in 2004 during his first administration, the plan had been shelved under Bolsonaro....

The plan has four pillars: strengthening monitoring and enforcement; promoting a sustainable economy; managing protected areas and determining how undesignated public forests should be used; and using regulations and financial incentives to curb deforestation. Measures included restoring sanctions for illegal forest clearing detected by satellites, a practice seen as the most effective tool to curb deforestation that was halted under Bolsonaro. The government also proposed barring properties with illegal deforestation from receiving bank loans and allocated more funding to priority Amazon municipalities that demonstrated reductions in forest loss. It also funded efforts to fight environmental crime and develop subsidized credit for sustainable businesses in the Amazon...

Deforestation and other land-use changes are Brazil's largest sources of greenhouse gas emissions, which drive global warming. The stakes are especially high in the Amazon, which stores vast amounts of carbon dioxide and generates atmospheric moisture that helps regulate weather far beyond South America... Degradation from wildfires, logging and drought affects about 40% of the Amazon and has outpaced clear-cutting in recent years. A strong El Niño, a periodic warming of the equatorial Pacific, could intensify those threats in 2026 and 2027 by bringing hotter, drier conditions that fuel wildfires.

The article notes that Lula's reelection campaign promised zero net deforestation by 2030, plus restoration to offset all forest loss, legal or illegal.
Microsoft

Microsoft Announces Open Source Tool Evaluating Your Software's Optimization For AI Coding Agents (microsoft.com) 27

The problem? Understanding how AI coding agents interact with the software you build. "Whether you're maintaining an SDK, building a command-line interface, or publishing an MCP server or skills... you need to understand whether agents can discover and use what you ship, and what your team can change."

Results can vary, and configurations keep changing, with behaviors influenced by everything from custom instructions and MCP servers to skills and plugins. So after a year of development Microsoft has created Scope, "an open-source platform built on Kubernetes for turning those interactions into evidence product teams can act on."

Details are available on... the Microsoft open source blog: Available under the MIT License, Scope supports a continuous Developer Agent Experience (DevAx) learning loop grounded in repeatable experiments.

The Azure Cosmos DB team's experience shows what that loop can deliver... "The evaluations led to 20 Agent Kit issues and 27 documentation issues resolved," [says Jay Gordon, Senior Program Manager, Azure Cosmos DB]... These results connect evaluation to decisions a product team can make: which documentation needs clarification, where tooling needs a fix, and whether an update changes agent behavior.... [The gains] demonstrate how targeted changes, informed by observed behavior, can improve the way agents use a product.

For more on the shift from building for human developers to supporting agents, watch Your Product Was Built for Humans. Is It Ready for Agents? or join us at AI DevCon NYC conference in November.

Scope surfaces everything from incorrect assumptions in documentation (or recurring missed instructions) to whether agents select the intended SDK, initialize it correctly, and use its APIs, leading to clearer descriptions for command-line tool and more actionable errors.

Microsoft's open source blog also explains why AI agent evaluation needs an open-source foundation: The challenges behind agent experience aren't unique to one product or organization. SDK maintainers, tool authors, researchers, and agent developers are all asking how agents behave and what helps them succeed. No single team can represent every language, workflow, or integration. An open project can bring more scenarios, more failure cases, and more viewpoints into the evaluation process... Opening Scope's execution and evaluation code gives contributors a way to question the methods, investigate unexpected results, and improve the evaluation itself. A shared foundation also reduces duplicated infrastructure. Agent integrations, reusable criteria, and trace-analysis improvements can help other teams study their own products without rebuilding the same machinery. The goal isn't one universal benchmark or definition of success. It's a common starting point that teams can adapt to their needs.

The MIT License lets teams use and extend Scope, while self-managed deployments let them evaluate private workloads without publishing their code or run data.... Scope streams activity as the agent works and retains interactions and workspace snapshots for later review. Your team can follow tool calls, inspect generated files, and connect a failed requirement to the steps that preceded it. Those traces provide observable evidence of what the agent did, helping turn a failure into a concrete documentation, SDK, or tooling improvement.

25% of Incoming Pull Requests May Be AI Slop, Finds Study From Linux Foundation Research (itsfoss.com) 26

"59% of maintainers report growing contribution volume since the rise of GenAI," according to a new study published by Linux Foundation Research. But 25% of their incoming pull requests "are estimated to be low-quality, also known as 'AI slop'." And on large projects, 69% see growing contributions — and estimate that 31% are low-quality/AI slop.

So what do these results show us? "Generative AI is fundamentally changing how people participate in open source," says the head of Open Source Ecosystem Development at Huawei's R&D subsidiary Futurewei, which helped support the study. Specifically GenAI is "lowering barriers to contribution" but also "creating new challenges" for maintainers and communities. Their recommendation? "Build the governance, transparency and trust mechanisms that allow AI-assisted contributions to strengthen, but not overwhelm, the open source ecosystem."

"Open source projects need to design for a growing AI-generated contributor base, not simply react to it," said Hilary Carter, SVP of Research at the Linux Foundation. "That means setting clear expectations for GenAI, putting responsibility for testing and disclosure on contributors and giving maintainers better tools to manage incoming pull requests. If we get those fundamentals right, AI can expand participation without overburdening and increasing costs for maintainers."

More from the blog It's FOSS: LF Research is the Linux Foundation's research arm. It was set up in 2021 and publishes studies on how open source is built and used, drawing on surveys and project data. Its latest report, Navigating Open Source Software Development in the Generative AI Era, surveyed 234 contributors and maintainers on how generative AI is affecting the way open source gets made...

64% say reviews now take longer. Burnout is their top concern at 63%, narrowly ahead of contribution quality at 60%.

You will also find that policies have not caught up to the AI-assisted coding and vulnerability reporting trend. Of the 119 respondents who answered the question, 35% said their project has a formal policy permitting AI use. Another 32% have none and no plans for one, 23% plan to write one, and 10% ban AI contributions outright....

Most maintainers (71%) say AI makes it easier for newcomers to start contributing.

Other interesting findings:
  • "Respondents estimate average time reductions across all six OSS development activities measured, including proposal discussions (19%) and code authoring (52%). For high-complexity tasks, however, 21% of respondents report taking more time when using GenAI."
  • "71% of maintainers agree GenAI reduces barriers to entry for OSS, but 53% of maintainers disagree that GenAI has improved community trust."
  • Developers are reinvesting the time they save back into open source: 66% report using productivity gains to address technical debt, 63% to develop new features and 58% for learning and upskilling.
  • Continued investment in human mentorship remains important: 46% of maintainers say GenAI increases the need for mentorship of new contributors, compared with 32% who say it decreases that need.

OpenSSF and LF AI & Data also helped support the study.

AI Use Convinces California Math Professor There's 'No Point' Grading Homework (dailycal.org) 148

From the student newspaper at the University of California, Berkeley: Richard Borcherds, a UC Berkeley professor and Fields medalist, no longer grades his students' homework. After seeing how many of his students used AI to consistently receive top scores, he felt there was "no point" in paying readers to grade for correctness in homework, as AI use is now unavoidable.

Borcherds revealed this in a sit-down interview Tuesday, following OpenAI's announcement that AI agents apparently solved one of mathematics' most difficult unsolved problems, the Navier-Stokes existence and smoothness problem. "If AI continues to improve at present rate, then, in a few years, there'll be nothing human mathematicians can do that AI can't do better," Borcherds said.

Borcherds said he currently grades on completion if a student hands in their homework. He admitted that it is "not a very good system," but at the moment, he has no alternative... Campus has tried several AI detection tools, including Turnitin and Rumi, but have determined that these tools aren't adequate enough to be standardized on campus.

The article points out that at the university, each class's AI policy "is up to the discretion of faculty."

A Newly Proposed Linux Filesystem Can Fix Corrupted Data (itsfoss.com) 67

BeamFS creator Aurelien Desbrieres is not calling for a merge, but is requesting feedback on an 18-patch proposal that takes the place of FTRFS, an earlier filesystem he proposed in April.

The Linux/Open Source blog It's FOSS reports: Filesystems that can repair damage, like Btrfs and ZFS, usually do it by falling back on a spare copy of the data. BeamFS skips that and stores Reed-Solomon error-correcting codes inside every block. Every read gets checked against those codes, and small amounts of damage are corrected before the data reaches the application. If the filesystem can tell the damage is beyond repair, the read fails with an error instead of returning the wrong bytes...

In his technical report, ext4 and ext3 returned wrong data without any error, while Btrfs refused to read the file. BeamFS returned the correct file every time except once, when a flip hit a pointer to the file's data and it refused the read.

"Aurelien says he used Anthropic's Claude to write the code, the tool that checks the patches, and the cover letter..."

America's Defense Department Is Building an 'Elite New Tech Sabotage Agency' (yahoo.com) 42

America's Defense Department "has spent months quietly building an elite new tech agency," reports Politico, "to help covertly disrupt and sabotage foreign technology programs considered threats to American military superiority." Information on the Technology Support Office, or TSO as it is called internally, is nearly impossible to find on Pentagon websites, and the agency is mentioned by name only in several previously unreported Defense Department historical records and memoranda. While the specifics of its work are highly classified, POLITICO spoke with 12 current and former U.S. national security officials with varying degrees of knowledge about TSO to understand how the agency came to be, the broad contours of its mission and why its operations are shrouded in secrecy...

[The Pentagon's Defense Secretary and Deputy Defense Secretary] established TSO quickly and without attracting outside scrutiny because they largely built the agency by reorganizing two classified Pentagon intelligence programs that have conducted similar clandestine tech-sabotage efforts at a smaller scale since 2023. But by creating an agency dedicated to expanding that work, the Defense Department is signaling its intent to ramp up a range of aggressive covert activities abroad — potentially including cyberattacks, supply chain disruptions and disinformation operations. Many of the people who spoke to POLITICO argued that the aggressive new initiative is needed to help the Pentagon counter foreign adversaries they say are harnessing artificial intelligence and advanced commercial technologies, such as drones, in creative ways that could erode America's military advantage...

While TSO lacks the legal authority to conduct clandestine operations directly, it works closely with senior U.S. military and intelligence officers to develop cutting-edge tools and strategies to disrupt adversaries' access to critical defense technologies — or subvert them from afar. TSO is staffed with engineers, special operators and intelligence officers, and its work spans everything from building bespoke hacking tools to planning elaborate deception operations that trick adversaries into installing faulty components — likely designed by TSO — in key foreign weapons platforms. TSO's overarching goal is to "buy time or stop adversaries from developing technologies" that would most threaten the U.S. military in a major conflict, said a former U.S. intelligence official who worked closely with the agency... A second former Pentagon official and a former U.S. national security official said the agency has told some defense contractors it's interested in offensive hacking capabilities. The former senior Pentagon intelligence official estimated that its budget for classified contracts alone is likely north of $1.5 billion.

They are seeking contractors on "the leading edge of technology," that official said, and hope to procure "a whole host of tools wherever your imagination can go."

Pentagon staff had been exploring the need for a new agency for over a year, the article explains. Creating a new agency with its own budget and procurement powers "would empower the agency to more quickly integrate cutting-edge tech from the private sector," Pentagon staff concluded, "and think more strategically about which foreign defense technologies pose the biggest threats across U.S. military organizations."

"Several people who spoke to POLITICO support TSO's mission but worry that the secrecy surrounding its work could embolden current Pentagon leadership to carry out missions that flout international law or funnel coveted classified contracts to political allies."

What if the Anti-AI Writing Police Make a Mistake? (cnn.com) 46

Writing contests face "a literary version of the ruined world" in Blade Runner, writes CNN. "Anxiety and suspicion about robot infiltrators are everywhere — and so are people claiming to hunt the robots down." Multiple companies now offer products that promise to spot the difference, with often contradictory, biased or erratic results. The makers of Pangram, an AI detection platform that has been cited as authoritative in many of the recent controversies, claim it can distinguish between human and synthetic writing with near-perfect accuracy... The company's own estimates claim that false positives — in which the tool wrongly reports that a piece of human writing was created — are 1 in 10,000 and shrinking. Peer-reviewed studies from the University of Chicago and the University of Brussels support that claim, though one 2025 study from the University of Maryland found that Pangram erroneously labeled 2% of documents as AI.

A widely referenced 2023 Stanford study that found AI writing detectors produced higher rates of false positives on writing from non-native English speakers was conducted before Pangram was created. Pangram ran an internal study using a database of non-native English texts and self-reported that false positive rate was around 8 in 10,000... Given the thousands upon thousands of pieces of writing published each day, a 1 in 10,000 chance of a false accusation — let alone an 8 in 10,000 chance — means that even the most trusted AI detector is going to be wrong, and wrong about a lot of people.

Pangram isn't able to tell users the truth about someone's writing, but it is able to introduce something much more complicated: doubt. Unless an accused writer confesses to using an LLM, there is no bulletproof way to prove an accusation, short of being given full access to someone's computer history and finding the chatbot prompts... To some people and institutions on the literary side, using automated AI writing detectors to fight the influx of AI writing is just trading one form of technological domination for another.

Pangram "has entered the public consciousness at a time of distrust that goes beyond writing," CNN notes, when people want to block "at least some of the daily overflow of misinformation and misrepresentation" recently studied by John Warner, the author of More Than Words: How to Think About Writing in the Age of AI .

But he's one of the people who believes AI-detecting tools can create a new dependence on another kind of machine. "Like all other technology of automation, that is going to de-skill people from discerning these things for themselves."

Wolves Descend On Finnish Villages After Google Hacked Down 1,300 Acres of Trees (futurism.com) 66

Google chopped down a quarter of a million trees in a rural Finnish town, reports the Guardian, noting that Google "illegally stripped the entire area... taking even the top soil with it... [A]ll that remains is a vast expanse of mud."

Google was then ordered to temporarily stop work by the Finnish Licensing and Supervision Authority, because it turns out Google "failed to complete the necessary environmental impact assessments before clearcutting the land." Futurism notes one result was wolves descending on a nearby village: In the felling-site near the Finnish village of Otanmäki, the ensuing loss of prey has forced packs of wolves to search for food elsewhere: nearby villages. "We had wolves coming into the village because all the wild animals moved out of the forest," 53-year-old Otanmäki resident Anni Ranta told the Guardian. "They fled."
An ecologist estimates that an additional 150,000 trees were chopped at another data center site, according to the Guardian, and because the trees were illegally chopped down, they can't be sold to timber companies.

And Futurism notes it's just the latest ecological issue facing data center buildouts: In West Virginia, a grove of critically endangered Chestnut trees is under threat of being bulldozed to make way for a new Anthropic hyperscale facility. Outside of Fort Wayne, a chunk of Indiana's once-bountiful wetlands is being tilled to fit a new Google data center. In Southern New Jersey, a data center operator was recently slapped with a $1 million fine after inspectors uncovered 62 illegal gas generators belching exhaust into the surrounding environment.

Microsoft Announces Per-Hour Cost for Xbox Cloud Gaming Service (gizmodo.com) 55

Microsoft has revealed pay-as-you-go pricing for Xbox Cloud Gaming, with introductory packages costing $3.99 for 10 hours, $7.99 for 25 hours, or $11.99 for 50 hours. Starting in November, Game Pass subscribers will receive only 5 to 15 included cloud-gaming hours depending on their tier and will have to buy additional time -- even to stream games they've already purchased. Gizmodo reports: Back in September, before these changes were announced, you paid full purchase price for a game that isn't in the Game Pass library on the assumption that you'd be able to play it via cloud streaming. Maybe your hardware doesn't meet the specs for this fancy new game. Maybe your gaming PC exploded/got stuck on a ship/had a component fail. Maybe you just want to be able to play it in bed on your laptop. Whatever. Now you find that in addition to the cost of the game you bought, you're going to be paying by the hour to play it once your monthly allotment of hours is up. If this is you, I expect you're not particularly amused. Thankfully, Microsoft notes that the playtime you purchase "remains available until it's used," so you won't have to worry about losing any unused time between gaming sessions.

UN Says Breaching 1.5C Warming Limit Is 'Imminent and Unavoidable' 357

For the first time, the UN has declared that exceeding the Paris Agreement's 1.5C warming limit is "imminent and unavoidable." "We are now saying this window has closed, but we can open it again by making the overshoot as brief as possible," UN Environment Program Executive Director Inger Andersen said on a call with reporters. "This is about how to find a way back as shortly and as quickly as possible with as limited an overshoot as possible." CNN reports: Past reports have examined the distance between countries' emissions reduction commitments and what it would take to limit global warming to 1.5 C above preindustrial levels. However, this year's report redefines the gap. Instead, it examines new emissions overshoot scenarios, and what it would take to limit peak warming to just 1.7 to 1.8 degrees C before bringing temperatures back down to 1.5 C through emissions cuts and the use of carbon removal technologies.

The report makes clear that every additional fraction of a degree of warming above 1.5 C "raises the risk of irreversible changes including in ice sheets, permafrost carbon, ocean circulation, and coral systems, along with devastating human impacts." Each added fraction of a degree of warming can have an "immense" impact "as measured in terms of damage, cost and loss of lives," said climate scientist Michael Mann of the University of Pennsylvania. Mann was not involved in producing the UNEP report.

According to the UNEP, which is based in Nairobi, the lowest overshoot scenario would keep peak warming to between 1.7 and 1.8 degrees C and return global average temperatures to at or below 1.5 C by 2100. However, to follow such a pathway, global greenhouse gas emissions would need to be slashed by far more than anything currently on the table at the upcoming COP31 talks. This would require an 18% cut by 2030, 45% by 2035, and 69% by 2040, relative to 2025 levels.

Meeting this lowest-possible overshoot scenario would require a tripling of renewable electricity capacity by 2035, and dramatic cuts to fossil fuels, including the phaseout of coal by 2040, the report states. In addition, there would need to be a major scaling up of carbon removal technologies, which so far have not been proven to work at such a large scale. In stark contrast to these figures, the fulfillment of existing emissions reduction pledges would only yield a 5-to-8% emissions cut by 2030 and an 11-to-15% reduction by 2035, the report found. This would be associated with a peak warming of about 2.6 degrees C.

If countries simply follow their current policies, then warming could reach a peak of about 2.8 C. That estimate has increased since last year, in part because of the withdrawal of the United States from the Paris Agreement and retraction of its emissions reduction commitments, the report states. Even the scenario that assumes countries meet their existing reduction commitments, and nations with net-zero pledges succeed in fulfilling them, still brings warming to a peak of 2.1 C.
