Users can filter by camera type and view descriptions, while a pre-order page offers a 2027 calendar of historic mission photography. The site also provides links to NASA data sources and audio.
New research suggests people can communicate and practice skills while dreaming (271 points by XzetaU8)
New research suggests people can communicate and practice skills while dreaming – The article explores the history and modern science of sleep learning, starting with Alois Benjamin Saliger’s 1932 “Psycho-phone” that played affirmations during sleep. Recent research indicates that people can indeed learn and even communicate while dreaming, raising questions about the ethical implications and limits of such abilities. The piece balances wonder with caution about the potential for misuse.
To Restore an Island Paradise, Add Fungi (17 points by Brajeshwar)
To Restore an Island Paradise, Add Fungi – Conservationists on Palmyra Atoll have removed 1.5 million invasive coconut palms and eradicated black rats to restore native Pisonia forests. A new study reveals that rare mycorrhizal fungi (some found nowhere else) are crucial for supporting Pisonia seedlings. Transplanting these fungi could accelerate restoration, highlighting the role of underground ecosystems in climate-resilient island recovery.
The smelly baby problem (132 points by dionysou)
The smelly baby problem – This column by Virginia Postrel traces the rapid shift from cloth diapers to disposables in mid-20th-century America. Dr. Benjamin Spock’s 1946 baby book advised buying two dozen cloth diapers, but within a decade, disposable diapers had largely replaced them due to convenience and changing household norms. The article examines how a mundane hygiene problem drove a massive consumer-product transformation.
I'm Peter Roberts, immigration attorney who does work for YC and startups. AMA (132 points by proberts)
I'm Peter Roberts, immigration attorney who does work for YC and startups. AMA – Peter Roberts, an immigration lawyer experienced with Y Combinator startups, hosts an AMA on Hacker News. A sample question involves a green-card holder living abroad who considers giving up family green cards while keeping his own for asset and travel reasons, reflecting common dilemmas for tech workers with global mobility.
Direct electrochemical black coffee quality appraisal using cyclic voltammetry (26 points by bookofjoe)
Direct electrochemical black coffee quality appraisal using cyclic voltammetry – Researchers demonstrate that cyclic voltammetry can measure coffee strength and roast darkness directly from a black coffee sample without preparation. The cathodic current correlates with strength, while current suppression after cycling indicates roast color, which affects flavour. This method decouples brewing strength from roast degree, offering a quantitative, sensor-based approach to coffee quality control.
A Report on Burnout in Open Source Software Communities (2025) [pdf] (42 points by susam)
A Report on Burnout in Open Source Software Communities (2025) – This PDF examines the prevalence and causes of burnout among open-source contributors, including maintainer fatigue, inadequate funding, and lack of recognition. The report likely includes survey data and recommendations for sustainable community practices. It highlights the human cost of the volunteer-driven model that powers much of modern software, including AI/ML frameworks.
Lib0xc: A set of C standard library-adjacent APIs for safer systems programming (95 points by wooster)
Lib0xc: A set of C standard library-adjacent APIs for safer systems programming – Microsoft’s open-source library lib0xc provides safer APIs for C programming, aiming to reduce memory-safety bugs without a full language overhaul. It enforces stricter warnings and offers bounded interfaces, targeting common pitfalls in systems code. While C cannot be made completely safe, the project addresses the growing need for reliability in foundational software, including AI runtime environments.
Ask HN: Who is hiring? (May 2026) (237 points by whoishiring)
Ask HN: Who is hiring? (May 2026) – The monthly Hacker News hiring thread for May 2026, with 237 points and 261 comments. Companies post vacancies with location and remote-status tags. An example post from Project Debug in Singapore (hybrid) hires engineers to manage mosquito populations using biological methods. The thread reflects the ongoing demand for tech talent across diverse industries.
Hardware evolution for AI-assisted education – The TI-84 Evo’s faster processor, larger display, and smarter menus mirror trends in edtech devices that incorporate AI-like assistance (e.g., hints, trace analysis). As AI tutoring systems proliferate, traditional calculators must evolve to remain relevant, suggesting a growing market for hybrid human–AI problem-solving tools in K–12 and higher education.
Sleep learning research reopens ethical AI frontiers – The New Yorker article revisits the dream-learning paradox, now backed by credible neuroscience. For AI/ML, this implies potential for “subconscious” skill acquisition (e.g., language training) and raises questions about data privacy during sleep. Companies building sleep-tracking or neuro-stimulation devices will need to navigate both opportunity and regulatory caution.
Low-cost electrochemical sensing meets AI-driven quality control – The coffee-appraisal paper shows how simple voltammetry combined with linear models can predict taste-relevant properties. This opens a path for AI-optimised, low-cost sensor networks in agriculture and food production—where edge AI can classify quality in situ, reducing waste and improving supply-chain transparency.
Burnout in open-source threatens the AI/ML supply chain – The OSS burnout report underscores a critical risk: many foundational AI/ML libraries (NumPy, PyTorch, scikit-learn) rely on overstretched maintainers. Without sustainable funding and community health, security and innovation could stall. Companies that benefit from these projects should invest in contributor support or risk supply-chain fragility.
Safer systems programming for AI reliability – Microsoft’s lib0xc addresses memory-safety bugs in C, a language still used in AI runtime kernels, operating systems, and embedded ML devices. As AI systems become safety-critical (e.g., autonomous driving, medical imaging), safer C APIs reduce the attack surface and runtime errors. This trend parallels wider industry moves toward Rust and formal verification for AI.
Remote-first hiring patterns reflect AI talent competition – The May 2026 hiring thread includes many remote and hybrid positions, especially for engineering roles. The AI/ML job market remains tight, with companies offering flexibility to attract top talent. Smaller startups and global teams benefit, but the trend also pressures firms to build robust remote collaboration and data-security infrastructure.
AI-driven satellite and space imagery analysis – The Artemis II photo timeline, with multiple cameras and detailed metadata, highlights the growing volume of space imagery. AI/ML models for object detection, terrain mapping, and anomaly detection are increasingly used to process such data. The pre-order calendar also signals consumer interest in visual space content, a niche that AI-enhanced photography tools can serve.
