ZDNet's Steven Vaughan-Nichols shares his list of "what's new and improved" in the latest Linux 6.16 kernel. An anonymous reader shares an excerpt from the report: First, the Rust language is continuing to become more well-integrated into the kernel. At the top of my list is that the kernel now boasts Rust bindings for the driver core and PCI device subsystem. This approach will make it easier to add new Rust-based hardware drivers to Linux. Additionally, new Rust abstractions have been integrated into the Direct Rendering Manager (DRM), particularly for ioctl handling, file/GEM memory management, and driver/device infrastructure for major GPU vendors, such as AMD, Nvidia, and Intel. These changes should reduce vulnerabilities and optimize graphics performance. This will make gamers and AI/ML developers happier. Linux 6.16 also brings general improvements to Rust crate support. Crate is Rust's packaging format. This will make it easier to build, maintain, and integrate Rust kernel modules into the kernel. For those of you who still love C, don't worry. The vast majority of kernel code remains in C, and Rust is unlikely to replace C soon. In a decade, we may be telling another story. Beyond Rust, this latest release also comes with several major file system improvements. For starters, the XFS filesystem now supports large atomic writes. This capability means that large multi-block write operations are 'atomic,' meaning all blocks are updated or none. This enhances data integrity and prevents data write errors. This move is significant for companies that use XFS for databases and large-scale storage. Perhaps the most popular Linux file system, Ext4, is also getting many improvements. These boosts include faster commit paths, large folio support, and atomic multi-fsblock writes for bigalloc filesystems. What these improvements mean, if you're not a file-system nerd, is that we should see speedups of up to 37% for sequential I/O workloads. If your Linux laptop doubles as a music player, another nice new feature is that you can now stream your audio over USB even while the rest of your system is asleep. That capability's been available in Android for a while, but now it's part of mainline Linux. If security is a top priority for you, the 6.16 kernel now supports Intel Trusted Execution Technology (TXT) and Intel Trusted Domain Extensions (TDX). This addition, along with Linux's improved support for AMD Secure Encrypted Virtualization and Secure Memory Encryption (SEV-SNP), enables you to encrypt your software's memory in what's known as confidential computing. This feature improves cloud security by encrypting a user's virtual machine memory, meaning someone who cracks a cloud can't access your data. Linux 6.16 also delivers several chip-related upgrades. It introduces support for Intel's Advanced Performance Extensions (APX), doubling x86 general-purpose registers from 16 to 32 and boosting performance on next-gen CPUs like Lunar Lake and Granite Rapids Xeon. Additionally, the new CONFIG_X86_NATIVE_CPU option allows users to build processor-optimized kernels for greater efficiency. Support for Nvidia's AI-focused Blackwell GPUs has also been improved, and updates to TCP/IP with DMABUF help offload networking tasks to GPUs and accelerators. While these changes may go unnoticed by everyday users, high-performance systems will see gains and OpenVPN users may finally experience speeds that challenge WireGuard.

Jack Dorsey's new app Bitchat is now available on the iOS App Store. The decentralized, peer-to-peer messaging app uses Bluetooth mesh networks for encrypted, ephemeral chats without requiring accounts, servers, or internet access. Dorsey said he built it over a weekend and cautioned that it "has not received external security review and may contain vulnerabilities..." TechCrunch reports: The app's UX is very minimal. There is no log-in system, and you're immediately brought to an instant messaging box, where you can see what nearby users are saying (if anyone is actually around you and using the app) and set your display name, which can be changed at any time. [...] Dorsey has not directly addressed the fake Bitchat apps on the Google Play store, but he did repost another user's X post that said that Bitchat is not yet on Google Play, and to "beware of fakes."

Cisco has donated its AGNTCY initiative to the Linux Foundation, aiming to create an open-standard "Internet of Agents" to allow AI agents from different vendors to collaborate seamlessly. The project is backed by tech giants like Google Cloud, Dell, Oracle and Red Hat. "Without such an interoperable standard, companies have been rushing to build specialized AI agents," writes ZDNet's Steven Vaughan-Nichols. "These work in isolated silos that cannot work and play well with each other. This, in turn, makes them less useful for customers than they could be." From the report: AGNTCY was first open-sourced by Cisco in March 2025 and has since attracted support from over 75 companies. By moving it under the Linux Foundation's neutral governance, the hope is that everyone else will jump on the AGNTCY bandwagon, thus making it an industry-wide standard. The Linux Foundation has a long history of providing common ground for what otherwise might be contentious technology battles. The project provides a complete framework to solve the core challenges of multi-agent collaboration: - Agent Discovery: An Open Agent Schema Framework (OASF) acts like a "DNS for agents," allowing them to find and understand the capabilities of others. - Agent Identity: A system for cryptographically verifiable identities ensures agents can prove who they are and perform authorized actions securely across different vendors and organizations. - Agent Messaging: A protocol named Secure Low-latency Interactive Messaging (SLIM) is designed for the complex, multi-modal communication patterns of agents, with built-in support for human-in-the-loop interaction and quantum-safe security. - Agent Observability: A specialized monitoring framework provides visibility into complex, multi-agent workflows, which is crucial for debugging probabilistic AI systems. You may well ask, aren't there other emerging AI agency standards? You're right. There are. These include the Agent2Agent (A2A) protocol, which was also recently contributed to the Linux Foundation, and Anthropic's Model Context Protocol (MCP). AGNTCY will help agents using these protocols discover each other and communicate securely. In more detail, it looks like this: AGNTCY enables interoperability and collaboration in three primary ways: - Discovery: Agents using the A2A protocol and servers using MCP can be listed and found through AGNTCY's directories. This enables different agents to discover each other and understand their functions. - Messaging: A2A and MCP communications can be transported over SLIM, AGNTCY's messaging protocol designed for secure and efficient agent interaction. - Observability: The interactions between these different agents and protocols can be monitored using AGNTCY's observability software development kits (SDKs), which increase transparency and help with debugging complex workflows You can view AGNTCY's code and documentary on GitHub.

An anonymous reader quotes a report from Ars Technica: The rise of large language models like ChatGPT has led to widespread concern that "everyone is cheating their way through college," as a recent New York magazine article memorably put it. Now, OpenAI is rolling out a new "Study Mode" that it claims is less about providing answers or doing the work for students and more about helping them "build [a] deep understanding" of complex topics. Study Mode isn't a new ChatGPT model but a series of "custom system instructions" written for the LLM "in collaboration with teachers, scientists, and pedagogy experts to reflect a core set of behaviors that support deeper learning," OpenAI said. Instead of the usual summary of a subject that stock ChatGPT might give -- which one OpenAI employee likened to "a mini textbook chapter" -- Study Mode slowly rolls out new information in a "scaffolded" structure. The mode is designed to ask "guiding questions" in the Socratic style and to pause for periodic "knowledge checks" and personalized feedback to make sure the user understands before moving on. It's unknown how many students will use this guided learning tool instead of just asking ChatGPT to generate answers from the start. In an early hands-off demo attended by Ars Technica, Study Mode responded to a request to "teach me about game theory" by first asking about the user's overall familiarity with the subject and what they'll be using the information for. ChatGPT introduced a short overview of some core game theory concepts, then paused to ask a question before providing a relevant real-world example. In another example involving a classic "train traveling at speed" math problem, Study Mode resisted multiple simulated attempts by the frustrated "student" to simply ask for the answer and instead tried to gently redirect the conversation to how the available information could be used to generate that answer. An OpenAI representative told Ars that Study Mode will eventually provide direct solutions if asked repeatedly, but the default behavior is more tuned to a Socratic tutoring style. OpenAI said it drew inspiration for Study Mode from "power users" and collaborated with pedagogy experts and college students to help refine its responses. As for whether the mode can be trusted, OpenAI told Ars that "the risk of hallucination is lower with Study Mode because the model processes information in smaller chunks, calibrating along the way." The current Study Mode prompt does, however, result in some "inconsistent behavior and mistakes across conversations," the company warned.

skam240 writes: President Donald Trump's administration on Tuesday proposed revoking a scientific finding that has long been the central basis for U.S. action to regulate greenhouse gas emissions and fight climate change. The proposed Environmental Protection Agency rule would rescind a 2009 declaration that determined that carbon dioxide and other greenhouse gases endanger public health and welfare. The "endangerment finding" is the legal underpinning of a host of climate regulations under the Clean Air Act for motor vehicles, power plants and other pollution sources that are heating the planet.

Opera will file a complaint against Microsoft to Brazilian antitrust authority CADE on Tuesday, alleging the tech giant gives its Edge browser an unfair advantage over competitors. Opera claims Microsoft pre-installs Edge as the default browser across Windows devices and prevents rivals from competing on product merits. The company's general counsel Aaron McParlan said Microsoft locks browsers like Opera out of preinstallation opportunities and frustrates users' ability to download alternative browsers. Opera, which says it is Brazil's third-most popular PC browser, wants CADE to investigate Microsoft and demand concessions to ensure fair competition.

Google has admitted its earthquake early warning system failed to accurately alert people during Turkey's deadly quake of 2023. From a report: Ten million people within 98 miles of the epicentre could have been sent Google's highest level alert -- giving up to 35 seconds of warning to find safety. Instead, only 469 "Take Action" warnings were sent out for the first 7.8 magnitude quake. Google told the BBC half a million people were sent a lower level warning, which is designed for "light shaking", and does not alert users in the same prominent way. The tech giant previously told the BBC the system had "performed well" after an investigation in 2023. The alerts system is available in just under 100 countries -- and is described by Google as a "global safety net" often operating in countries with no other warning system. Google's system, named Android Earthquake Alerts (AEA), is run by the Silicon Valley firm - not individual countries.

Apple has lost its fourth AI researcher in a month to Meta [non-paywalled source], marking the latest setback to the iPhone maker's AI efforts. From a report: Bowen Zhang, a key multimodal AI researcher at Apple, left the company on Friday and is set to join Meta's recently formed superintelligence team, according to people familiar with the matter. Zhang was part of the Apple foundation models group, or AFM, which built the core technology behind the company's AI platform. Meta previously lured away the leader of the team, Ruoming Pang, with a compensation package valued at more than $200 million, Bloomberg News has reported. Two other researchers from that group -- Tom Gunter and Mark Lee -- also recently joined Meta. AFM is made up of several dozen engineers and researchers across Cupertino, California, and New York. In response to the job offers from Meta and others, Apple has been marginally increasing the pay of its AFM staffers, whether or not they've threatened to leave, said the people, who asked not to be identified because the moves are private. Still, the pay levels pale in comparison with those of rivals.

60% of American adults use AI to search for information, but far fewer have adopted the technology for workplace productivity, according to a new Associated Press-NORC Center for Public Affairs Research poll. Only 37% of respondents reported using AI for work tasks, while 40% said they use it for brainstorming ideas. The survey of 1,437 adults, conducted July 10-14, reveals a significant generational gap in AI adoption. Among adults under 30, 74% use AI for information searches and 62% for generating ideas, compared to just 23% of those over 60 who use it for brainstorming. About one-third of Americans use AI for writing emails, creating or editing images, or entertainment purposes. A quarter use it for shopping, while 16% report using AI for companionship -- a figure that rises to 25% among younger adults.

The Airbus A380, the world's largest commercial passenger jet, faces mounting maintenance challenges as regulatory authorities issue an increasing number of safety directives. The European Union Aviation Safety Agency has listed 95 airworthiness directives for the A380 since January 2020, approximately double the number issued for large Boeing aircraft during the same period. The directives address problems including leaking escape slides, cracked seals, and a ruptured landing-gear axle. A comprehensive maintenance check of the massive plane requires 60,000 hours of labor, according to aircraft repairer Lufthansa Technik. Airlines remain committed to operating the twin-deck aircraft due to limited large-capacity alternatives, with Boeing's 777X years behind schedule and Airbus unable to produce long-haul A350s quickly enough. British Airways plans to overhaul A380 cabins starting next year, while Emirates intends to keep flying the aircraft until the end of the next decade.

India has overtaken China to become the top source of smartphones sold in the US, after Apple shifted to assemble more of its iPhones in the South Asian country. From a report: In the quarter through June, India was the largest manufacturer of smartphones shipped to the US for the first time, accounting for 44% of the market, according to Canalys data. Vietnam, home to much of Samsung's production, came in second. China fell from having more than 60% of all estimated shipments a year ago to just 25%. The stark change comes as Apple ramped up its production in India and smartphone makers "frontload device inventories amid tariff concerns," Canalys researchers wrote. The volume of made-in-India devices more than tripled in the past quarter from a year earlier. Apple's iPhone shipments to the US declined by 11%, reflecting distortions to its usual pattern due to unusually high shipments to stockpile units earlier in the year.

Priority inversion comes about when a low-priority task holds a resource that is also needed by a high-priority task, preventing the latter from running. This problem is made much worse if the low-priority task is unable to gain access to the CPU and, as a result, cannot complete its work and free the resources it holds. Proxy execution is a potential solution to this problem, but it is a complex solution that has been under development for several years; LWN first looked at it in 2020. The 6.17 kernel is likely to contain an important step forward for this long-running project.

Utilities across the U.S. are demanding tech companies pay larger shares of electricity infrastructure costs as AI drives unprecedented data center construction, creating tensions over who bears the financial burden of grid upgrades. Virginia utility Dominion Energy received requests from data center developers requiring 40 gigawatts of electricity by the end of 2024, enough to power at least 10 million homes, and proposed measures requiring longer-term contracts and guaranteed payments. Ohio became one of the first states to mandate companies pay more connection costs after receiving power requests exceeding 50 times existing data center usage. Tech giants Microsoft, Google, and Amazon plan to spend $80 billion, $85 billion, and $100 billion respectively this year on AI infrastructure, while utilities worry that grid upgrade costs will increase rates for residential customers.

An anonymous reader quotes a report from SFGATE: During the 2010s' boom in on-demand services such as Uber and DoorDash, Wag staked a claim to the market for dog walking. It became a buzzy, high-flying company, at one point gaining a valuation of around $650 million, and grew to offer a whole range of tech products for pet care. But as the years passed, struggles mounted and profits remained elusive. On July 21, Wag filed (PDF) for bankruptcy. To stay alive, the San Francisco-headquartered company is now using bankruptcy court to restructure in what's known as a Chapter 11 process. Its lines of business -- including gig-work dog walking and sitting, pet insurance, and the veterinary tool "Furscription" -- will remain open, according to a news release. If a judge approves Wag's restructuring plan, it will take the company off the public markets and into the private hands of a company called Retriever. On the same day of the bankruptcy filing, Wag's chief financial officer, Alec Davidian, submitted a document (PDF) supporting and explaining the move. He wrote that Wag's "monthly revenues declined rapidly after March 2020 as a result of the COVID-19 pandemic" and pointed to $69.5 million in losses from 2022 through 2024. The losses weren't Wag's only problem. The company had taken out debt in 2022 when it went public, and in that loan agreement, it had set a minimum level of cash Wag would need to have on hand at all times. This year, Wag dropped below that amount, Davidian wrote. Wag also failed to find a third-party deal to get more money, the CFO noted, and its debt obligations are set to mature in August, meaning the company was "facing a dire liquidity crisis." So, Wag opted for the bankruptcy proceeding, in which it plans to eliminate the 2022 debt, which is currently held by Retriever. "Through the Restructuring," Davidian wrote, "[Wag] will emerge from these Chapter 11 Cases a stronger company, with a more sustainable capital structure that is better aligned with [Wag's] present and future operating prospects."

PayPal has launched "Pay with Crypto" for U.S. merchants, enabling acceptance of over 100 cryptocurrencies with lower cross-border transaction fees and instant conversion to USD or its stablecoin PYUSD. "Businesses of all sizes face incredible pressure when growing globally, from increased costs for accepting international payments to complex integrations," said Alex Chriss, president and chief executive of PayPal. "Today, we're removing these barriers and helping every business of every size achieve their goals. [...] By enabling seamless cross-border crypto payments, we're breaking longstanding barriers in global commerce." SiliconANGLE reports: Using the new Pay with Crypto, merchants can now accept payments in the form of numerous cryptocurrency tokens, including bitcoin, Ethereum, USD Tether and Solana. The transaction fee rate will be 0.99% for the first year, increasing to 1.5% thereafter. The company said that rate is significantly lower than international credit card fees. "Imagine a shopper in Guatemala buying a special gift from a merchant in Oklahoma City," added Chriss. "Using PayPal's open platform, the business can accept crypto for payments, increase their profit margins, pay lower transaction fees, and get near instant access to proceeds." Merchants who accept cryptocurrency tokens can instantly convert them to dollars or PYUSD, the company's stablecoin, which is a type of cryptocurrency that maintains parity with USD so that every token is always worth $1. Funds stored as PYUSD on PayPal also earn 4% annual rewards. The company said the new service will roll out for U.S. merchants in the coming weeks. [...] Pay with Crypto will initially support cryptocurrency wallets from Coinbase, OKX, Binance, Kraken, Phantom, MetaMask and Exodus, with more planned.
