On the 50th anniversary of the USENIX organization, its flagship Annual Technical Conference (ATC) is coming to an end.

For the past two decades, as more USENIX conferences have joined the USENIX calendar by focusing on specific topics that grew out of ATC itself, attendance at ATC has steadily decreased to the point where there is no longer a critical mass of researchers and practitioners joining us. Thus, after many years of experiments to adapt this conference to the ever-changing tech landscape and community, the USENIX Board of Directors has made the difficult decision to sunset USENIX ATC.

Many important technologies first saw the light of day at this event.

Stratolaunch successfully flew its uncrewed Talon-A2 prototype to hypersonic speeds twice -- once in December and again in March. "We've now demonstrated hypersonic speed, added the complexity of a full runway landing with prompt payload recovery and proven reusability," Stratolaunch President and CEO Zachary Krevor said in a statement on Monday. "Both flights were great achievements for our country, our company and our partners." Space.com reports: Microsoft co-founder Paul Allen established Stratolaunch in 2011, with the goal of air-launching satellites from a giant carrier plane called Roc, which has a wingspan of 385 feet (117 meters). That vision changed after Allen's 2018 death, however; the company is now using Roc as a platform to test hypersonic technology. Hypersonic vehicles are highly maneuverable craft capable of flying at least five times the speed of sound. Their combination of speed and agility make them much more difficult to track and intercept than traditional ballistic missiles. The United States, China and other countries view hypersonic tech as vital for national security, and are therefore developing and testing such gear at an ever-increasing pace. Stratolaunch, Roc and the winged, rocket-powered Talon-2A are part of this evolving picture, as the two newly announced test flights show. They were both conducted for the U.S. military's Test Resource Management Center Multi-Service Advanced Capability Hypersonic Test Bed (MACH-TB) program, under a partnership with the Virginia-based company Leidos. On both occasions, Roc lifted off from California and dropped Talon-2A over the Pacific Ocean. The hypersonic vehicle then powered its way to a landing at Vandenberg Space Force Base, on California's Central Coast. "These flights were a huge success for our program and for the nation," Scott Wilson, MACH-TB program manager, said in the same statement. "The data collected from the experiments flown on the initial Talon-A flight has now been analyzed and the results are extremely positive," he added. "The opportunity for technology testing at a high rate is highly valuable as we push the pace of hypersonic testing. The MACH-TB program is pleased with the multiple flight successes while looking forward to future flight tests with Stratolaunch."

An anonymous reader quotes a report from TechCrunch: Spyware maker NSO Group will have to pay more than $167 million in damages to WhatsApp for a 2019 hacking campaign against more than 1,400 users. On Tuesday, after a five-year legal battle, a jury ruled that NSO Group must pay $167,256,000 in punitive damages and around $444,719 in compensatory damages. This is a huge legal win for WhatsApp, which had asked for more than $400,000 in compensatory damages, based on the time its employees had to dedicate to remediate the attacks, investigate them, and push fixes to patch the vulnerability abused by NSO Group, as well as unspecified punitive damages. The trial, as well as the whole lawsuit, prompted a series of revelations, such as the location of the victims of the 2019 spyware campaign, as well as the names of some of NSO Group's customers. The ruling marks the end -- pending a potential appeal -- of a legal battle that started in more than five years ago, when WhatsApp filed a lawsuit against the spyware maker. The Meta-owned company accused NSO Group of accessing WhatsApp servers and exploiting an audio-calling vulnerability in the chat app to target around 1,400 people, including dissidents, human rights activists, and journalists. NSO Group's spokesperson Gil Lainer left the door open for an appeal. "We will carefully examine the verdict's details and pursue appropriate legal remedies, including further proceedings and an appeal," Lainer said in a statement.

Rep. Kat Cammack (R-FL) introduced the App Store Freedom Act [PDF] on Tuesday, legislation that would compel "large app store operators" with over 100 million US users to permit third-party app stores and allow them to be set as defaults. The bill directly challenges Apple's walled garden approach and Google's Play Store dominance by requiring both companies to allow developers to use alternative payment systems, bypassing the platforms' commission structures. It would also mandate equal access to development tools and interfaces without discrimination, while giving users the ability to remove pre-installed apps. Violations would trigger FTC enforcement with penalties up to $1 million per infraction. The legislation mirrors recent European Union regulations that have already forced Apple to permit third-party app stores and allow users to change default apps.

Amazon's Zoox said it has issued a software recall for 270 of its robotaxis after a crash in Las Vegas last month. CNBC reports: The recall surrounds a defect with the vehicle's automated driving system that could cause it to inaccurately predict the movement of another car, increasing "the risk of a crash," according to a report submitted to the National Highway Traffic Safety Administration on May 1. Zoox submitted the recall after an April 8 incident in Las Vegas in which an unoccupied Zoox robotaxi collided with a passenger vehicle, the NHTSA report states. There were no injuries in the crash and only minor damage occurred to both vehicles. "After analysis and rigorous testing, Zoox identified the root cause," the company said in a blog post. "We issued a software update that was implemented across all Zoox vehicles. All Zoox vehicles on the road today, including our purpose-built robotaxi and test fleet, have the updated software." Zoox paused all driverless vehicle operations while it reviewed the incident. It has since resumed operations after rolling out the software update.

According to the Washington Post (paywalled), the Trump administration plans to eliminate the Energy Star program -- a long-standing EPA initiative that has saved Americans over $500 billion in energy costs since 1992. "The organization states that the average American saves about $450 per year on energy bills by choosing appliances that have been Energy Star-certified," adds Engadget. From the report: The EPA hasn't said when this would go into effect and when consumers would stop seeing Energy Star certifications on home appliances. It's technically illegal for a presidential administration to end this program without Congress, but the same goes for many of Trump's pronouncements and executive orders. "Eliminating the Energy Star program would directly contradict this administration's promise to reduce household energy costs," Paula Glover, president of the nonprofit coalition Alliance to Save Energy, told CNN. "For just $32 million a year, Energy Star helps American families save over $40 billion in annual energy costs. That's a return of $350 for every federal dollar invested."

An anonymous reader quotes a report from Ars Technica: Google's accelerated Android release cycle will soon deliver a new version of the software, and it might look quite different from what you'd expect. Amid rumors of a major UI overhaul, Google seems to have accidentally published a blog post detailing "Material 3 Expressive," which we expect to see revealed at I/O later this month. Google quickly removed the post from its design site, but not before the Internet Archive saved it. It has been a few years since Google introduced any major changes to its Material theming, but the design team wasn't just sitting idly this whole time. According to the leaked blog post, Google has spent the past three years working on a more emotionally engaging vision for Android design. While the original Material Design did an admirable job of leveraging colors and consistent theming, it could make apps look too similar. The answer to that, apparently, is Material 3 Expressive. Google says this is "the most-researched update to Google's design system, ever." The effort reportedly included 46 separate studies with hundreds of sample designs. The team showed these designs to more than 18,000 study participants to understand how the user experience would work. In these studies, the design team used a variety of metrics, including the following: - Eye tracking: Analyzing where users focus their attention - Surveys and focus groups: Gauging emotional responses to different designs - Experiments: Gathering sentiment and preferences - Usability: Seeing how quickly participants could understand and use an interface "The result of all this is an interface that appears much more varied than the previous Material Design," writes Ars. You can check out 9to5Google's article, which preserved many of the blog post's visuals before they were removed.

President Trump's proposed 2026 budget seeks to cut nearly $500 million from CISA, accusing the agency of prioritizing censorship over cybersecurity and election protection. "The proposed cuts -- which are largely symbolic at this stage as they need to be approved by Congress -- are framed as a purge of the so-called 'censorship industrial complex,' a term the White House uses to describe CISA's work countering misinformation," reports The Register. From the report: In its fiscal 2024 budget request, the agency had asked [PDF] for a total of just over $3 billion to safeguard the nation's online security across both government and private sectors. The enacted budget that year was about $34 million lower than the previous year's. Now, a deep cut has been proposed [PDF], as the Trump administration decries the agency's past work tackling the spread of misinformation on the web by America's enemies, as well as the agency's efforts safeguarding election security. [...] "The budget eliminates programs focused on so-called misinformation and propaganda as well as external engagement offices such as international affairs," it reads [PDF]. "These programs and offices were used as a hub in the censorship industrial complex to violate the First Amendment, target Americans for protected speech, and target the President. CISA was more focused on censorship than on protecting the nation's critical systems, and put them at risk due to poor management and inefficiency, as well as a focus on self-promotion."

With iOS 18.5, Apple is bringing carrier-based satellite connectivity to the entire iPhone 13 lineup, allowing users with compatible carrier plans (like T-Mobile's Starlink-powered service) to access satellite features in areas without traditional coverage. The update is expected to launch next week. 9to5Mac reports: It's important to note that this update does not bring Apple's Emergency SOS via satellite to the iPhone 13 series. That feature relies on specialized hardware found only in iPhone 14 and later and functions independently of carrier networks. It also doesn't "install Starlink" on every iPhone, just support for carrier-provided satellite features like Starlink. By contrast, carrier-provided satellite services behave more like conventional cellular connections and require a participating plan to work.

An anonymous reader quotes a report from TechCrunch: Google on Tuesday announced the launch of Gemini 2.5 Pro Preview (I/O edition), an updated version of its flagship Gemini 2.5 Pro AI model that the company claims tops a number of widely used benchmarks. Gemini 2.5 Pro Preview (I/O edition) is available via the Gemini API and Google's Vertex AI and AI Studio platforms, and is priced the same as the Gemini 2.5 Pro model it effectively replaces. It's also in Google's Gemini chatbot app for the web and for mobile devices. The model's release comes ahead of Google's annual I/O developer conference (hence the "I/O edition" designation), where Google is expected to unveil a host of models, as well as AI-powered tools and platforms. [...] According to Google, Gemini 2.5 Pro Preview (I/O edition) has "significantly" improved capabilities for coding and building interactive web apps. The model is also better at tasks like code transformation -- that is, modifying a piece of code to achieve a specific goal -- and code editing, the company says. Google says the Gemini 2.5 Pro Preview (I/O edition) leads the WebDev Arena Leaderboard, a benchmark measuring a model's ability to create aesthetically pleasing and functional web apps. It also achieved a score of 84.8% on VideoMME, a popular benchmark designed to evaluate the video analysis capabilities of multi-modal large language models.

Linux systems can have large filesystems; trying to keep up with the stream of fanotify filesystem-monitoring notifications for them can be a struggle. Fanotify is one of a few ways to monitor accesses to filesystems provided by the kernel. Song Liu led a discussion on how to improve in-kernel filtering of fanotify events to a joint session of the filesystem and BPF tracks at the 2025 Linux Storage, Filesystem, Memory-Management, and BPF Summit. He wants to combine the best parts of a few different approaches to efficiently filter filesystem events.

Chief executives are exiting their posts at an unprecedented rate as economic volatility and emerging challenges reshape corporate leadership decisions, according to data from executive tracking firm Challenger, Gray & Christmas. Public-company CEO departures reached 373 last year, jumping 24% from 2023 levels. Among U.S. businesses with at least 25 employees, 2,221 chief executives left their positions in 2024, the highest number since Challenger began monitoring departures in 2002. Corporate leaders are citing AI, tariffs, recession fears and scrutiny of diversity initiatives as key stressors driving the exodus. "It's a very difficult time to lead," said Blake Irving, former GoDaddy CEO. "Given all the weird gyrations going on in the economy and with our new administration, it's really hard for even great leaders to find a true north." The trend extends beyond the C-suite, with managers 1.7 times more likely to report high workplace stress than rank-and-file employees, according to a recent McLean & Co. survey of over 200,000 workers.

In a combined filesystem and memory-management session at the 2025 Linux Storage, Filesystem, Memory Management, and BPF Summit (LSFMM+BPF), Joanne Koong led a discussion on improving the writeback performance for the Filesystem in Userspace (FUSE) layer. Writeback is how data that is written to the filesystem is actually flushed to the disk; it is the process of writing dirty pages from the page cache to storage. The current FUSE implementation allocates unmovable memory, then copies the dirty data to it before initiating writeback, which is slow; Koong wanted to change that behavior. Since the session, she has posted a patch set that has been applied by FUSE maintainer Miklos Szeredi.

English regulators have approved a new law firm that uses AI instead of lawyers to offer services for as little as $2.67, as the technology continues to disrupt industries from finance to accounting. From a report: Garfield AI, which was founded by a former London litigator and a quantum physicist, is an online tool that allows businesses and individuals such as tradespeople to chase debts owed to them at a substantially lower cost than the average lawyer's fees. Its AI assistant guides claimants through the small claims court process, including creating "polite chaser" letters for $2.67 and filing documents such as claim forms for $67, and can also produce arguments for claimants to use at trial. AI models are increasingly encroaching on legally sensitive tasks in high-paying sectors such as law and finance, potentially undercutting fees in high-volume work. Garfield received approval from the Solicitors Regulation Authority, the legal regulator for England and Wales, in March, in a move the latter hailed as a "landmark moment" for the industry.

Reddit's Steve Huffman isn't mincing words about what he found when he came back as CEO in 2015: a company full of idealists who weren't exactly killing themselves with hard work. "We were really idealistic, and that's been good in many ways, but we were also idealistic about not being a business," Huffman said on the "Prof G Pod" podcast. "Wrapped up in some of that idealism was also not working very hard," he added. Huffman sees this as a Silicon Valley disease: "It's almost an entitlement of, 'I work at these companies, but I don't have to work very hard and I'm here for myself.'"

Recent college graduates face the worst job market in decades, with unemployment reaching 5.8%, according to recently released New York Federal Reserve data. The "recent-grad gap" - the difference between unemployment rates of young college graduates versus the overall labor force - has hit its lowest point in four decades, indicating college graduates are facing unusual difficulties securing employment. (The New York Federal Reserve said labor conditions for recent college graduates have "deteriorated noticeably" in the past few months.) Even graduates from elite MBA programs are struggling to find work, while law school applications have surged as young people seek shelter from the difficult job market. Economists are attributing the decline to three potential factors: incomplete recovery from pandemic disruptions, diminishing returns on college education, and possibly AI replacing entry-level positions. "When you think about what generative AI can do, it's the kind of things that young college grads have done," said David Deming, a Harvard economist. "They read and synthesize information and data. They produce reports and presentations."
