Gemini 4 Carbon has been announced as the company’s strongest model yet, featuring state-of-the-art cybersecurity and long-horizon capabilities. The release positions it as a major upgrade for advanced, security-focused AI tasks.

More than ten days after Apple was notified of the eMudhra CA compromise, the git, curl, and python3 tools shipped with macOS still trust the compromised certificates. The issue remains unresolved despite the notification.

The new MacBook Pro features a PROLED XDR display and touch input, with the display billed as the world’s best laptop display. It runs on M5 Pro or M5 Max chips, positioning it as a powerful platform for AI.

ICE’s Homeland Security Investigations is conducting one of the largest anti-left surveillance operations in U.S. history, according to the report. The far-reaching spying on left-wing activists is described as rivaling FBI and CIA crackdowns on the Civil Rights and anti-war movements.

Readers discussing the piece focused on anti-LLM “magic strings” and prompt-injection tricks used to fingerprint or filter AI-generated contributions, such as asking assistants to tag pull requests with a robot emoji. They note that Anthropic’s once-published refusal-testing string no longer reliably triggers refusals and was removed from the API and docs, while models’ inconsistent responses show how brittle such fingerprinting methods can be.

A US agency has approved Amazon Leo’s $11.5 billion acquisition of Globalstar, bringing the satellite operator’s assets and spectrum into Amazon’s competition with Starlink. The deal is expected to preserve Globalstar’s satellite services for Apple devices, including iPhone Emergency SOS, while advancing Amazon’s broader satellite connectivity ambitions.

CNC stone carving may seem out of place in ancient Gothic architecture, but medieval builders were themselves at the forefront of technology in their time. Using modern CNC machines could help make the construction of new Gothic architecture a practical reality today.

A Git-like version control system for US legislation would let lawyers read statutes as they stood on any date and trace each phrase back to the law that wrote it. An example history of nine US Code titles was built by replaying every amendment.

A discussion around AlpineBSD suggests Linux-friendly BSD projects may draw initial interest by reducing unfamiliarity but struggle to retain contributors due to BSD’s demanding committer path and difficult contributor experience. Commenters argue a more opinionated, pkgsrc-based installation could be more viable, while also noting broader tensions around FreeBSD governance and AI-related fragmentation in FOSS.

Amazon has agreed to acquire satellite firm Globalstar for $11.57 billion, bringing its satellite assets and spectrum into Amazon’s competition with SpaceX’s Starlink. The deal would preserve Globalstar’s satellite services for Apple devices, which became a major part of its business after Apple’s iPhone Emergency SOS feature and roughly $1.5 billion in Apple investment. Globalstar’s survival followed a 2002 bankruptcy and a rebuilt constellation that helped restore capacity.

A new introductory textbook, Start Doing Graph Theory, aims to teach readers graph theory by applying it to puzzles, theorem proofs, and other problems. It presents the subject as a hands-on toolkit rather than abstract theory, covering a broad range of uses.

A Massachusetts factory is using a factory-scale robot to build circuit boards on demand, claiming turnaround times twice as fast as a typical Shenzhen quick-turn shop. The setup highlights a U.S.-based alternative for rapid PCB prototyping and production.

At least 10 people died when one high-speed train struck another near Toledo, Spain, causing two carriages to derail. Rescuers are searching the wreckage, and authorities warn the death toll could rise.

Readers are skeptical that Nvidia and Micron’s outsized contribution to U.S. earnings reflects broad economic strength, seeing it more as a bubble or temporary fluctuation masking a weak, K-shaped economy. The discussion highlights concentration in AI-driven profits and Baumol-style cost pressures, where lucrative tech sectors raise costs for other services while many businesses and workers struggle.

The Agent SDK is a framework for building managed agents such as Bugbot, Security Reviewer, and Rollouts. It lets developers define agents in code and deploy them with a single command.

A visualization illustrates U.S. wealth inequality by showing median household wealth as a 9-inch stack of $100 bills, compared with a 145-foot stack for the average top-1% household. The scale highlights the enormous gap between typical families and the wealthiest Americans.

A Tesla Semi caught fire on I-880 in Hayward with no crash involved, closing the freeway for 10 hours. While truck fires are common, this incident raises questions that need answers.

Apple is automatically blocking certificates linked to the compromised eMudhra intermediate CAs. Mac administrators can take optional steps to address affected command-line tools.

New court documents reveal that Meta has worked to control the scientific narrative around its products, strengthening comparisons between the tech industry and tobacco. The filings suggest the company sought to shape research and public understanding in ways that echo past tobacco-industry tactics.

At least 10 people have died and scores more were injured in a high-speed train collision in Spain’s Toledo province. The accident occurred on the line connecting Madrid to southern Andalusia.

Moderators of r/Seattle say they discovered that archive.today was injecting malware links into archived pages and have banned the service, though the claim has not been externally validated. The move follows long-standing concerns about archive.today’s behavior, including past reports that it used visitors for DDoS attacks.

Ole Bielfeldt of Germany won the top prize in the Nikon Small World contest for a microscopic video showing an inkjet printer depositing ink onto paper. The winning image captures the precise motion of ink droplets as they land on the page.

An Anthropic team member argues that the traditional coding interview no longer provides useful hiring signal, at least for their team. They offer an optimistic take that this shift creates a major opportunity for junior engineers, with hunger mattering more than tenure.

In the latest installment of its Gaussian splatting series, PlayCanvas details how it bypassed GPU Scene instance caps, implemented Streamed SOG LODs, and managed GPU memory budgets for production-ready photogrammetry. These changes bring the renderer to a point where it can finally claim to be “unlimited”—maybe.

Dayjob: Tax is a new benchmark that evaluates AI agents across 50 realistic tax assignments, testing how well they navigate messy records and apply professional judgment. It aims to measure whether agents can deliver reliable tax work in practical environments.

Rob Manuel, creator of Fesshole and co-founder of B3ta, has created “81 Jokes for the ZX81,” an absurd self-set project featuring 81 jokes he wrote and illustrated himself for the vintage computer. The collection leans into the retro constraints of the ZX81 platform.

Researchers explain soap-film colors as a fixed white minus a cosine transform of the CIE color-matching functions evaluated at twice the film’s optical thickness. The computed color sequence matches Newton’s thin-film table, and thick films fade to white because that transform decays.

Assembly Nights appears to make the case for returning to low-level programming as a way to counter skill atrophy from heavy Claude/Codex use and keep engineering fundamentals sharp. Readers are receptive to the idea, with discussion turning to practical choices like NASM versus FASM and whether GDB is the right tool for debugging assembly.

A Hacker News post announcing a personal strike this November sparked debate about whether tech workers can organize collective action and resist AI-driven productivity pressures. Commenters were largely skeptical that an individual strike would matter, while some managers argued engineers who oppose AI tools risk being managed out as output and metrics improve. The thread also reflected broader frustration over locked-down devices, cloud dependence, and the declining affordability of independent computing hardware.

SlideBySide is a new Show HN tool that lets users upload a PDF or PowerPoint, share a link, and present together without screen sharing. It offers shared slide control, live cursors, and drawing, and requires no account.
