A tech writer argues that an old smartphone can replace a Raspberry Pi for many DIY projects because it already includes the camera, GPS, storage, battery, and mobile data that would otherwise need to be assembled separately. Using second-hand hardware can therefore be cheaper and simpler than building around a Pi.

Tech companies are again reshaping the notion of privacy, moving from a personal-choice framing to one where one person’s device can affect everyone nearby. Meta and Google’s smart glasses can record what the wearer sees or use AI to describe it, and similar AI-enabled audio features are raising new bystander-privacy concerns.

PyPI’s redesigned project pages are now live, adding clearer security signals so users can more easily check where release files come from. The update includes a dedicated security tab, a rebuilt release files tab, and refreshed documentation.

Italy’s privacy regulator fined Meta €805 million over photo privacy, saying the company failed to obtain users’ “specific” consent for handling their photos. The penalty adds to Meta’s mounting regulatory challenges in Europe.

A discussion around a family tree of software job titles argues that labels such as Scrum Master, Product Owner, and DevOps Engineer have become inconsistent and often meaningless across companies, with expectations varying widely even within the same organization. Commenters say DevOps especially suffers from unrealistic expectations and burnout because development and operations require different skills and lifestyles, including on-call and incident pressure. The broader takeaway is that titles will keep evolving, and roles like SRE or Cloud Infrastructure Engineer show how software careers mutate over time.

LinkedIn and Monster have taken down more than 1,000 fake job postings following a CBC News investigation. The probe found that over 1,500 misleading listings on the platforms were connected to a multi-level marketing company.

Google’s Project Zero is switching to a straight 90-day vulnerability disclosure deadline, publishing details 90 days after a report. The change ends its since-2021 “90+30” policy, which gave vendors up to 90 days to remediate plus an additional 30-day window after a patch before disclosure.

The Claude Delusion’s critique of Bill Gates as an overconfident judge of AI coding progress drew pushback from readers, who argue his decades of software experience make him a credible authority even if his 1970s programming background is less relevant to modern systems. Commenters also suggest the author’s skepticism toward LLM engineering may be shaping a selective argument that dismisses Gates as a biology nonexpert while downplaying his software credentials.

A retrospective traces 3Com’s rise from Bob Metcalfe’s networking innovations through the dot-com boom and iconic 3C509 network card, explaining how the once-dominant brand faded rather than exited with fanfare. Despite its early influence, 3Com was ultimately absorbed into HP, ending its run as an independent networking company.

Researchers have formalized the U.S. tax code in Lean, allowing formal search across encoded rules. The approach surfaced previously unidentified loopholes by systematically exploring legal interpretations. It highlights formal methods as a potential tool for auditing complex regulations.

Bloomberg’s investigation into Penlink’s Webloc ad-based surveillance system has found that security agencies worldwide use it, building on prior Citizen Lab research. The reporting identifies additional customers of the system.

A new piece titled “Possible Futures” presents a map of possible futures, framing uncertainty as a set of alternative scenarios rather than a single forecast. It invites readers to explore how different trajectories might unfold and be compared.

A new side-by-side comparison showcases all 13 display modes of The Secret of Monkey Island across eight editions, including Hercules, CGA, EGA, VGA, Amiga, Atari ST, Macintosh, FM Towns, and Sega CD. Using the same 12 scenes, it highlights how the 1990 classic looked across different platforms.

Readers discussing the Ask HN thread suggest the most useful concrete AI skills are engineering fundamentals—especially scaling verification through testing practices, clear problem framing, and knowing when an LLM is stuck—rather than generic prompt tricks. Others recommend hands-on experience building models or harnesses around completion models to understand how LLMs actually behave. Some argue the core skill is management-style communication and requirements structuring, especially when working with cheaper or less capable models.

A new Show HN project offers a live and replayable map of U.S. air traffic during the FAA’s nationwide ground stop on Nov. 13, 2026. It visualizes flights airborne compared with a normal Friday, along with departures and the resulting backlog at major airports.

This piece offers a visual explanation of reinforcement learning, using graphics to clarify how the machine-learning approach works. It serves as an accessible overview of core reinforcement-learning concepts.

A study of three open-source models—Alibaba’s Qwen 3, Google’s Gemma 3, and Meta’s Llama 3.1—found that generative AI can use more energy and show accuracy disparities on non-English text, with some languages triggering repeated output and sharp token/energy spikes. Critics noted the article buries key methodology details and that the models tested are already dated.

Anthropic has upgraded Claude Code Projects so it can run parallel AI workers hands-free. The Projects coordinator is now proactive, answering questions and posting thread status updates directly in chat.

A Wall Street Journal profile of Nvidia interim CEO Colette Kress sheds light on how Nvidia controversially financed its own customers to drive demand, allegedly helping keep GPU prices high through circular financing deals. The report adds scrutiny to Nvidia’s sales practices amid questions over pricing and customer relationships.

A discussion around writing a PostScript interpreter notes that the language’s stack-machine design is simple enough for hobby projects—including a PostScript Deflate decompressor—but that real implementations are made complex by graphics and font rendering, with Ghostscript’s speed drawing admiration. Commenters also share practical uses like editing PDFs and generating puzzles, while lamenting that PostScript expertise is often treated as just another embedded/software skill.
