Mozilla has warned that the U.S. Department of Justice's proposed remedies in its antitrust case against Google would harm independent browsers and reduce competition in the browser market. The DOJ and several state attorneys general last week filed revised proposed remedies in the U.S. v. Google search case that would prohibit all search payments to browser developers, a move Mozilla says would disproportionately impact smaller players.

"These proposed remedies prohibiting search payments to small and independent browsers miss the bigger picture -- and the people who will suffer most are everyday internet users," said Mark Surman, President of Mozilla. Unlike Apple and Microsoft, which generate revenue from hardware and operating systems, Mozilla relies primarily on search revenue to fund browser development. Mozilla argues that cutting these payments would not solve search dominance but would instead strengthen the position of tech giants.

Mozilla also warned that the proposal threatens its ability to maintain Gecko, one of only three major browser engines alongside Google's Chromium and Apple's WebKit. "If we lose our ability to maintain Gecko, it's game over for an open, independent web," Surman said, noting that even Microsoft abandoned its browser engine in 2019. "If Mozilla is unable to sustain our browser engine, it would severely impact browser engine competition and mean the death of the open web as we know it -- essentially, creating a web where dominant players like Google and Apple, have even more control, not less."

Firefox serves 27 million monthly active users in the U.S. and nearly 205 million globally.

An anonymous reader quotes a report from Ars Technica: Researchers at Harvard University led the study, and it included nearly 58,000 adults in Japan who were followed for up to a year using a database of medical records from routine checkups. Researchers found that when people switched from being nondrinkers to drinkers during the study, they saw a drop in their "bad" cholesterol -- aka low-density lipoprotein cholesterol or LDL. Meanwhile, their "good" cholesterol -- aka high-density lipoprotein cholesterol or HDL -- went up when they began imbibing. HDL levels went up so much, that it actually beat out improvements typically seen with medications, the researchers noted.

On the other hand, drinkers who stopped drinking during the study saw the opposite effect: Upon giving up booze, their bad cholesterol went up and their good cholesterol went down. The cholesterol changes scaled with the changes in drinking. That is, for people who started drinking, the more they started drinking, the lower their LDL fell and higher their HDL rose. In the newly abstaining group, those who drank the most before quitting saw the biggest changes in their lipid levels.

Specifically, people who went from drinking zero drinks to 1.5 drinks per day or less saw their bad LDL cholesterol fall 0.85 mg/dL and their good HDL cholesterol go up 0.58 mg/dL compared to nondrinkers who never started drinking. For those that went from zero to 1.5 to three drinks per day, their bad LDL dropped 4.4 mg/dL and their good HDL rose 2.49 mg/dL. For people who started drinking three or more drinks per day, their LDL fell 7.44 mg/dL and HDL rose 6.12 mg/dL. For people who quit after drinking 1.5 drinks per day or less, their LDL rose 1.10 mg/dL and their HDL fell by 1.25 mg/dL. Quitting after drinking 1.5 to three drinks per day, led to a rise in LDL of 3.71 mg/dL and a drop in HDL of 3.35. Giving up three or more drinks per day led to an LDL increase of 6.53 mg/dL and a drop in HDL of 5.65. The study has been published in JAMA Network Open.

Google says its new open-source AI model, Gemma 3, achieves nearly the same performance as DeepSeek AI's R1 while using just one Nvidia H100 GPU, compared to an estimated 32 for R1. ZDNet reports: Using "Elo" scores, a common measurement system used to rank chess and athletes, Google claims Gemma 3 comes within 98% of the score of DeepSeek's R1, 1338 versus 1363 for R1. That means R1 is superior to Gemma 3. However, based on Google's estimate, the search giant claims that it would take 32 of Nvidia's mainstream "H100" GPU chips to achieve R1's score, whereas Gemma 3 uses only one H100 GPU.

Google's balance of compute and Elo score is a "sweet spot," the company claims. In a blog post, Google bills the new program as "the most capable model you can run on a single GPU or TPU," referring to the company's custom AI chip, the "tensor processing unit." "Gemma 3 delivers state-of-the-art performance for its size, outperforming Llama-405B, DeepSeek-V3, and o3-mini in preliminary human preference evaluations on LMArena's leaderboard," the blog post relates, referring to the Elo scores. "This helps you to create engaging user experiences that can fit on a single GPU or TPU host."

Google's model also tops Meta's Llama 3's Elo score, which it estimates would require 16 GPUs. (Note that the numbers of H100 chips used by the competition are Google's estimate; DeepSeek AI has only disclosed an example of using 1,814 of Nvidia's less-powerful H800 GPUs to server answers with R1.) More detailed information is provided in a developer blog post on HuggingFace, where the Gemma 3 repository is offered.

An anonymous reader quotes a report from Ars Technica: On Tuesday, OpenAI unveiled a new "Responses API" designed to help software developers create AI agents that can perform tasks independently using the company's AI models. The Responses API will eventually replace the current Assistants API, which OpenAI plans to retire in the first half of 2026. With the new offering, users can develop custom AI agents that scan company files with a file search utility that rapidly checks company databases (with OpenAI promising not to train its models on these files) and navigate websites -- similar to functions available through OpenAI's Operator agent, whose underlying Computer-Using Agent (CUA) model developers can also access to enable automation of tasks like data entry and other operations.

However, OpenAI acknowledges that its CUA model is not yet reliable for automating tasks on operating systems and can make unintended mistakes. The company describes the new API as an early iteration that it will continue to improve over time. Developers using the Responses API can access the same models that power ChatGPT Search: GPT-4o search and GPT-4o mini search. These models can browse the web to answer questions and cite sources in their responses. That's notable because OpenAI says the added web search ability dramatically improves the factual accuracy of its AI models. On OpenAI's SimpleQA benchmark, which aims to measure confabulation rate, GPT-4o search scored 90 percent, while GPT-4o mini search achieved 88 percent -- both substantially outperforming the larger GPT-4.5 model without search, which scored 63 percent.

Despite these improvements, the technology still has significant limitations. Aside from issues with CUA properly navigating websites, the improved search capability doesn't completely solve the problem of AI confabulations, with GPT-4o search still making factual mistakes 10 percent of the time. Alongside the Responses API, OpenAI released the open source Agents SDK, providing developers free tools to integrate models with internal systems, implement safeguards, and monitor agent activities. This toolkit follows OpenAI's earlier release of Swarm, a framework for orchestrating multiple agents.

Sphere Entertainment Co, the company behind the Las Vegas Sphere, said they are considering opening scaled-down versions of the immersive venue in other cities. AV Magazine reports: While this has been been feasible for its high-profile residencies such as U2, the Eagles, Dead & Company and Anyma, smaller venues could attract a broader range of artists who might not have the budget or demand to fill the flagship Las Vegas location. By scaling down the size while retaining the signature technology, Sphere Entertainment Co can offer a similar spectacle at a more sustainable cost for artists and spectators.

The possibility of mini-Spheres follows news that a full-scale venue will open in the UAE as a result of a partnership between Sphere Entertainment Co and the Department of Culture and Tourism -- Abu Dhabi. Beyond concerts, the Las Vegas Sphere has proven successful with immersive films such as V-U2: An Immersive Concert Film and the Sphere Expeience featuring Darren Aronofsky's Postcard from Earth, which In January passed 1,000 screenings. "As we enter a new fiscal year, we see significant opportunities to drive our Sphere business forward in Las Vegas and beyond," said Dolan. "We believe we are on a path toward realizing our vision for this next-generation medium and generating long-term shareholder value."

An anonymous reader quotes a report from the Washington Post: An Amazon-backed self-driving taxi failed to meet vehicle safety standardsbecause it lacks basics like a brake pedal and rearview mirrors, according to a report by federal inspectors that raises questions about the industry's plans to put a new generation of autonomous vehicles on U.S. roads. The National Highway Traffic Safety Administration report was produced as part of a review last year of an unusual vehicle by Amazon subsidiary Zoox that, without a steering wheel or other human controls, has no way for a person to drive. Zoox has asserted that the vehicle's technology, backed by artificial intelligence, complies with the agency's standards. But the NHTSA report documents "apparent noncompliances" with eight safety rules.

The contents of the previously undisclosed review suggest that rules written when autonomous vehicles were the stuff of futuristic musings pose a legal impediment to the industry's ambitions, even as plans for self-driving vehicles accelerate. Zoox has a small pilot fleet on the roads in California and Nevada and says it has completed thousands of trips carrying employees and guests. It is finalizing plans to launch public service in Las Vegas this year. [...] By documenting the apparent noncompliances of the Zoox, NHTSA could be setting the table for a recall, under agency procedures. It is unclear whether the Trump administration will attempt a change in course. The agency said it remains in discussion with Zoox and was "considering all options."

Zoox could have sought an exemption from the safety rules, but NHTSA has never granted one to an autonomous passenger vehicle. Instead, the company self-certified that its vehicle complied with the rules as it raced to be the first company to put a purpose-built robotaxi on the road and claim a share of what could become a multi trillion-dollar market. Zoox's vehicle bears little resemblance to a normal car. The plan is for customers to summon a ride using an app, much like a regular ride-hailing vehicle, getting in through bus-like doors and sitting facing one another. The vehicle navigates itself, seeing the world through a set of cameras and laser-based sensors. It largely relies on its own abilities to drive, but the company says teams of remote operators can seize control to help handle unusual situations. Passengers can call for assistance via a touch screen and open the doors using an emergency release. "We will continue to support transportation technology innovation while maintaining the safety of America's roads," NHTSA said in a statement.

"Our recent discussions with NHTSA are about mirrors, windshield wipers, a defroster, and a foot-activated brake pedal -- equipment that makes sense for vehicles with human drivers, but not for the Zoox purpose-built robotaxi," Zoox said in a statement. "Our purpose-built design means that the robotaxi can never be operated by a human driver, and our AI driver doesn't rely on this equipment to view the world."

Dustin Moskovitz, CEO and co-founder of Asana, is stepping down and will transition to the role of Chair once a new CEO is appointed. "As I reflect on my journey since co-founding Asana nearly 17 years ago, I'm filled with immense gratitude," Moskovitz said in a statement. "Creating and leading Asana has been more than just building a company -- it's been a profound privilege to work alongside some of the most talented minds in the industry." Asana's stock price was down more than 25% following the news. CNBC reports: Asana said fourth-quarter sales rose 10% year over year to $188.3 million, which was in line with analysts' estimates. The company said its adjusted earnings per share was breakeven, ahead of analysts' estimates of a loss of one cent per share. Asana said it expects fiscal first-quarter revenue of $184.5 million to $186.5 million, trailing analysts' expectations of $191 million.

Moskovitz owns about 53% of the company's outstanding shares, between his Class A and Class B holdings. He has substantially increased his ownership since the company's public market debut in 2020. [...] Moskovitz said in his Monday retirement statement that he plans to focus more on his philanthropic endeavors, such as Good Ventures and Open Philanthropy, which cites "potential risks from advanced AI" among its various focus areas. In 2010, Moskovitz signed the Giving Pledge, a promise by some of the wealthiest people in the world to donate most of their fortunes to charity.

An anonymous reader quotes a report from TechCrunch: When Bluesky CEO Jay Graber walked on stage at SXSW 2025 for her keynote discussion, she wore a large black T-shirt with her hair pulled back into a bun. At first glance, it might appear as though she's following the same playbook that so many women in tech leadership have played before: downplaying her femininity to be taken seriously. The truth is way more interesting than that. What might look like your average black T-shirt is a subtle, yet clear swipe at Mark Zuckerberg, a CEO who represents everything that Bluesky is trying to work against as an open source social network.

The Meta founder and CEO has directly compared himself to the Roman emperor Julius Caesar. His own shirt declared Aut Zuck aut nihil, which is a play on the Latin phrase aut Caesar aut nihil: "Either Caesar or nothing." Graber's shirt -- which directly copies the style of a shirt that Zuckerberg wore onstage recently -- says Mundus sine caesaribus. Or, "a world without Caesars." With the way Bluesky is designed, Graber is certainly putting her money where her mouth (or shirt) is. As a decentralized social network built upon an open source framework, Bluesky differs from legacy platforms like Facebook in that users have a direct, transparent window into how the platform is being built. "If a billionaire came in and bought Bluesky, or took it over, or if I decided tomorrow to change things in a way that people really didn't like, then they could fork off and go on to another application," Graber explained at SXSW. "There's already applications in the network that give you another way to view the network, or you could build a new one as well. And so that openness guarantees that there's always the ability to move to a new alternative."

An anonymous reader shares a report: AI excels at following instructions -- but it's not pushing the boundaries of knowledge, says Thomas Wolf. The chief science officer and cofounder of Hugging Face, an open-source AI company backed by Amazon and Nvidia, analyzed the limits of large language models. He wrote that the field produces "overly compliant helpers" rather than revolutionaries. Right now, AI isn't creating new knowledge, Wolf wrote. Instead, it's just filling in the blanks between existing facts -- what he called "manifold filling."

Wolf argues that for AI to drive real scientific breakthroughs, it needs to do more than retrieve and synthesize information. AI should question its own training data, take counterintuitive approaches, generate new ideas from minimal input, and ask unexpected questions that open new research paths. Wolf also weighed in on the idea of a "compressed 21st century" -- a concept from an October essay by Anthropic's CEO Dario Amodei, "Machine of Loving Grace." Amodei wrote that AI could accelerate scientific progress so much that discoveries expected over the next 100 years could happen in just five to 10.

"I read this essay twice. The first time I was totally amazed: AI will change everything in science in five years, I thought!" Wolf wrote on X. "Re-reading it, I realized that much of it seemed like wishful thinking at best." Unless AI research shifts gears, Wolf warned, we won't get a new Albert Einstein in a data center -- just a future filled with "yes-men on servers."

Red Hat product manager Pau Garcia Quiles (also long-time Slashdot reader paugq) spotted an interesting project on GitHub: Free95, a new lean, Windows-compatible operating system is available from GitHub. In its current form, it can run very basic Win32 GUI and console applications, but its developer promises to keep working on it to reach DirectX and even game compatibility.
"Free95 is your friendly Windows Environment with an added trust of the open source community," according to its README file. (It's licensed under the GPL-3.0 license.) And in answer to the question "Why?" it responds "To remove Windows's bloat, and security problems. Being controlled by a large corporation is unsettling."

"It's still in-development of course," the developer post recently on Reddit, "and I'll appreciate anyone who'd like to contribute." In one comment they claim Free95 is "much more lightweight, simpler and faster than ReactOS." And looking to the future, they add "I might do DirectX stuff and make some games run. Or, what about DOOM?"

The Open Source Initiative's Board of Directors election "has become embroiled in controversy..." writes Steven J. Vaughan-Nichols at The New Stack.

"The real issue is the community's opposition to the open source AI definition (OSAID), which the organization released last October," he adds — but "the election process has been criticized because the OSI has refused to accept the candidacy of Debian developer Luke Faraone, citing a missed application deadline." Faraone claims they submitted their application around 9 p.m. PST on Feb. 17, while the OSI maintains the deadline was 11:59 p.m. UTC (3:59 p.m. PST) on the same day.

The dispute has raised a firestorm about the clarity of communication regarding deadlines and time zones. Critics argue that the deadline's time zone was not clearly specified on the OSI's public-facing website. Tracy Hinds, chair of OSI, acknowledged this oversight but stated that full members received multiple emails with the correct time zone information. "Everyone who is qualified to run for elections (full members of OSI) received emails with the time zone," wrote Hinds, in an email to The New Stack. "The public-facing web page did not have the time zone, and we've now updated it for clarity going forward.

"Extending the deadline would be unfair to the other candidates...."

On LinkedIn, Bruce Perens, one of the OSI's founders wrote, "Open Source Initiative invents rule at the last minute to deny opposition candidate's nomination for their board election."
There are three board sets up for election in March, the article points out. "Two well-known figures in the open source world — Richard Fontana, Red Hat's principal commercial counsel and a former OSI board member, and [Bradley] Kuhn, policy fellow and hacker-in-residence at the Software Freedom Conservancy — are running on a joint platform of repealing the open source AI definition."

In a blog post Faraone promised a similar platform (also supporting a repeal of the definition) — had their candidacy not been rejected.

Equuleus42 (Slashdot reader #723) brings word that the Electronic Frontier Foundation (EFF) is sharing a new tool for fighting back against cellphone surveillance by Stingray cell-site simulators.

Android Authority reports: "Rayhunter" uses an open-source software package designed to look for evidence of IMSI catchers in action, running on an old Orbic Speed RC400L mobile hotspot. The great thing about that choice is that you can pick one up for practically nothing — we're seeing them listed for barely over $10 on Amazon, and you can find them even cheaper on eBay. There's an installation script for Macs and Linux to automate getting set up, but once the Orbic is flashed with the Rayhunter software, it should be ready go, collecting data about sketchy-looking "cell towers" it picks up.

Right now, much of the use of IMSI catchers is still shrouded in mystery, with the groups who regularly employ them extremely hesitant to disclose their methods. As a result, a big focus of this EFF project is just getting more info on how and where these are actually used, giving protestors a better sense of the steps they'll need to take if they want to protect their privacy.

President Trump has signed an executive order to establish a strategic reserve of cryptocurrencies by using tokens already owned by the government. Reuters reports: A "Strategic Bitcoin Reserve" will be capitalized with bitcoin owned by the federal government that was seized as part of criminal or civil asset forfeiture proceedings, the White House crypto czar, billionaire David Sacks, said in a post on social media platform X. The order kept open the possibility of the government buying bitcoin in future. The U.S. commerce and treasury secretaries "are authorized to develop budget-neutral strategies for acquiring additional bitcoin, provided that those strategies impose no incremental costs on American taxpayers," a factsheet on the White House website said. "This is the most underwhelming and disappointing outcome we could have expected for this week," Charles Edwards, founder of bitcoin-focused hedge fund Capriole Investments, wrote in a post on X. "No active buying means this is just a fancy title for Bitcoin holdings that already existed with the Govt. This is a pig in lipstick."

Europe's new tech rule aims to keep digital markets open and is not targeted at U.S. tech giants, EU antitrust and tech chiefs told U.S. congressmen, reminding them that U.S. enforcers have in recent years also cracked down on these companies. From a report: The comments by EU antitrust chief Teresa Ribera and EU tech chief Henna Virkkunnen came after U.S. House Judiciary Chair Jim Jordan and Scott Fitzgerald, chairman of the subcommittee on the administrative state, regulatory reform and antitrust demanded clarifications on the Digital Markets Act (DMA).

"The DMA does not target U.S. companies," Ribera and Virkkunnen wrote in a joint letter dated March 6 to Jordan and Fitzgerald seen by Reuters. "It applies to all companies which fulfil the clearly defined criteria for being designated as a gatekeeper in the European Union irrespective of where they are headquartered," they said.

A Brazilian judge has ordered Apple to open its iOS platform to alternative app stores within 90 days, according to Valor International. The ruling cited Apple's compliance with similar requirements in the European Union under the Digital Markets Act without showing "significant impact or irreparable harm to its economic model."

The case originated from a 2022 complaint by Mercado Livre. Brazil previously issued a 20-day deadline in November for Apple to permit alternative payment options and sideloading, but that injunction was overturned in December. Apple plans to appeal.

Earlier this week, Meta chief product officer Chris Cox said the company's upcoming open-source Llama 4 AI will help power AI agents for hundreds of millions of businesses. CNBC reports: The AI agents won't just be responding to prompts. They will be capable of new levels of reasoning and action -- surfing the web and handling many tasks that might be of use to consumers and businesses. And that's where Shih comes in. Meta's AI is already being used by over 700 million consumers, according to Shih, and her job is to bring the same technologies to businesses. "Not every business, especially small businesses, has the ability to hire these large AI teams, and so now we're building business AIs for these small businesses so that even they can benefit from all of this innovation that's happening," she told CNBC's Julia Boorstin in an interview for the CNBC Changemakers Spotlight series.

She expects the uptake among businesses to happen soon, and spread far and wide. "We're quickly coming to a place where every business, from the very large to the very small, they're going to have a business agent representing it and acting on its behalf, in its voice -- the way that businesses today have websites and email addresses," Shih said. While major companies across sectors of the economy are investing millions of dollars to develop customer LLMs, "doing fancy things like fine tuning models," as Shih put it, "If you're a small business -- you own a coffee shop, you own a jewelry shop online, you're distributing through Instagram -- you don't have the resources to hire a big AI team, and so now our dream is that they won't have to."

For both consumers and businesses, the implications of the advances discussed by Cox and Shih will be significant in daily life. For consumers, Shih says, "Their AI assistant [will] do all kinds of things, from researching products to planning trips, planning social outings with their friends." On the business side, Shih pointed to the 200 million small businesses around the world that are already using Meta services and platforms. "They're using WhatsApp, they're using Facebook, they're using Instagram, both to acquire customers, but also engage and deepen each of those relationships. Very soon, each of those businesses are going to have these AIs that can represent them and help automate redundant tasks, help speak in their voice, help them find more customers and provide almost like a concierge service to every single one of their customers, 24/7."

AmiMoJo writes: China plans to issue guidance to encourage the use of open-source RISC-V chips nationwide for the first time, Reuters reports, citing two sources briefed on the matter, as Beijing accelerates efforts to curb the country's dependence on Western-owned technology.

The policy guidance on boosting the use of RISC-V chips could be released as soon as this month, although the final date could change, the sources said. It is being drafted jointly by eight government bodies, including the Cyberspace Administration of China, China's Ministry of Industry and Information Technology, the Ministry of Science and Technology, and the China National Intellectual Property Administration, they added.

Apple has refreshed its MacBook Air lineup with the M4 processor, adding a new sky blue color option and reducing prices across the board. The 13-inch model now starts at $999, while the 15-inch begins at $1,199. Both models are available to order immediately and will ship on March 12.

The updated MacBook Airs feature the same thin design as previous generations but now include the 12-megapixel Center Stage webcam found in current MacBook Pro models. Both variants come with the M4 chip, aligning them with Apple's recent Mac Mini, iMac, and MacBook Pro refreshes.

Base configurations include an M4 with a 10-core CPU and 8-core GPU, 16GB of unified memory, and 256GB of storage. Customers can upgrade to a 10-core GPU (matching the base 14-inch MacBook Pro), 32GB of RAM, and up to 2TB of storage. A significant technical improvement is the support for two external 6K displays while keeping the laptop's lid open, addressing a limitation of previous Air models.

An anonymous reader quotes a report from TechCrunch: Google has open sourced an AI model, SpeciesNet, designed to identify animal species by analyzing photos from camera traps. Researchers around the world use camera traps -- digital cameras connected to infrared sensors -- to study wildlife populations. But while these traps can provide valuable insights, they generate massive volumes of data that take days to weeks to sift through. In a bid to help, Google launched Wildlife Insights, an initiative of the company's Google Earth Outreach philanthropy program, around six years ago. Wildlife Insights provides a platform where researchers can share, identify, and analyze wildlife images online, collaborating to speed up camera trap data analysis.

Many of Wildlife Insights' analysis tools are powered by SpeciesNet, which Google claims was trained on over 65 million publicly available images and images from organizations like the Smithsonian Conservation Biology Institute, the Wildlife Conservation Society, the North Carolina Museum of Natural Sciences, and the Zoological Society of London. Google says that SpeciesNet can classify images into one of more than 2,000 labels, covering animal species, taxa like "mammalian" or "Felidae," and non-animal objects (e.g. "vehicle"). SpeciesNet is available on GitHub under an Apache 2.0 license, meaning it can be used commercially largely sans restrictions.
