Show HN: 18 Words (403 points by pompomsheep)
18 Words – A daily word challenge game where players try to guess a word within 18 attempts, with features like hints, letter reveals, and sharing scores. The game includes an archive and links to the creator’s other game, Zanagrams.
No leap second will be introduced at the end of December 2026 (98 points by ChrisArchitect)
No leap second at end of December 2026 – The International Earth Rotation and Reference Systems Service (IERS) Bulletin C announces that no leap second will be added to UTC in December 2026. The current offset between UTC and TAI remains at -37 seconds, and future adjustments depend on Earth’s rotation.
Launch HN: Context.dev (YC S26) – API to get structured data from any website (12 points by TheYahiaBakour)
Context.dev (YC S26) – A web scraping and crawling API designed for AI agents, providing structured data (markdown, images, sitemaps, etc.) from any website. It aims to replace custom scraping infrastructure and multiple vendors, letting developers pull live web data on demand.
Opinionated and Easy Pi.dev Configuration (19 points by lwhsiao)
LazyPi – Opinionated Pi.dev Configuration – A one‑command setup tool that installs 60+ community skills, 67 themes, MCP support, sub‑agents, memory, and Claude Code integration for the Pi coding agent. It reduces research and configuration overhead, offering a curated starting point for Pi users.
TLS certificates for internal services done right (25 points by mrl5)
TLS certificates for internal services done right – Explains a “split‑horizon DNS” approach to get valid TLS certificates for internal services (e.g., Grafana) using a public apex domain and ACME automation. This avoids self‑signed certificates or ignoring TLS errors, making internal HTTPS both secure and painless.
PostHog Open Sourced (58 points by thatxliner)
PostHog Open Sourced (FOSS mirror) – A read‑only mirror of the PostHog product analytics platform with all proprietary code removed. The repo (595 stars, 104 forks) is automatically synced from the main PostHog repository, allowing the community to inspect and fork the open‑source components.
Show HN: Analog Watch (34 points by ezekg)
Analog Watch – A minimalist web game that challenges players to read three analog clocks as fast as possible. It’s a simple, fun timing exercise with no further details provided.
New open access book on history of computers and politics (16 points by mckelveyf)
New open access book on history of computers and politics – Published by MIT Press, the book (titled Simpolitics) examines the intersection of computing technology and political systems. The content preview is unavailable, but it’s a scholarly work available under open access.
Meta reuses old RAM in new servers with custom bridge chip (205 points by ihsw)
Meta reuses old RAM in new servers with custom bridge chip – Meta developed a custom CXL chip called “Vistara” to reuse older DIMMs in new servers, addressing memory shortages without buying expensive new RAM. The approach leverages the longer lifespan of memory chips and avoids performance penalties by decoupling the older RAM via CXL.
Show HN: LastShelf – an emergency map of your family's documents bills& contacts (16 points by sbrown12)
LastShelf – emergency map of family documents – A service that helps users organize wills, insurance, passwords, and important contacts into a structured, step‑by‑step guide for loved ones during medical emergencies or after death. It offers a trial and focuses on reducing stress by providing clear instructions ahead of time.
Web data infrastructure is becoming a commodity for AI agents
Context.dev exemplifies the shift from custom scraping pipelines to turnkey APIs that supply live, structured web data to AI agents. This trend lowers the barrier for agents that require up‑to‑date external knowledge (beyond training cutoffs) and will accelerate the development of retrieval‑augmented generation (RAG) systems.
AI coding agents are getting “opinionated” starter kits
LazyPi shows that the ecosystem around coding agents (like Pi) is maturing: users want zero‑config setups with pre‑integrated skills, themes, and toolchain support (MCP, sub‑agents, memory). This points to a future where AI development tools are as plug‑and‑play as modern IDEs, enabling rapid onboarding for both novices and experts.
Open‑source analytics platforms remain vital for AI product builders
PostHog’s FOSS mirror signals that even successful AI‑powered products (PostHog includes session recording, feature flags, and product analytics) maintain a strong open‑source community. For AI/ML teams, this means they can inspect, modify, and self‑host analytics without vendor lock‑in—critical for privacy‑sensitive AI applications.
Hardware reuse and cost optimization are AI infrastructure priorities
Meta’s custom CXL bridge chip to reuse older RAM in new servers highlights a growing trend: as AI workloads drive massive memory demand, hyperscalers seek creative ways to cut costs without sacrificing performance. This will inspire more heterogeneous memory architectures and CXL‑based disaggregation in AI clusters.
AI is expanding into personal continuity and emergency planning
LastShelf.ai applies AI (or at least an AI‑branded interface) to help families organize critical documents before a crisis. This reflects a broader trend of “life‑admin AI” – tools that use structured workflows and intelligent prompts to handle emotionally charged logistics. Expect more AI‑powered services for end‑of‑life planning, healthcare coordination, and estate management.
The line between “AI” and “conventional software” continues to blur
Several articles (word game, analog clock, leap second) have no AI/ML content, yet they appear alongside AI‑focused launches. This suggests the Hacker News audience values diverse technical topics, but for AI/ML practitioners the key insight is that many non‑AI projects (e.g., TLS certificate automation, hardware reuse) are enablers of reliable AI infrastructure.
Automated web data extraction is becoming agent‑native
Context.dev’s tagline “the web data API for AI‑native software” captures a core trend: AI agents need real‑time, structured web content just as humans use browsers. This will drive standardization of web‑to‑API pipelines and may lead to new data licensing models as agents consume web pages at scale.
