Show HN: Beauty Arena – An Elo-based experiment to measure aestheticshttps://beautyarena.vercel.appHi HN,I built Beauty Arena to solve a data problem I've always found annoying: absolute rating scales (1-10) are terrible for subjective data. They suffer from massive inflation and inconsistent user baselines (one person's 7 is another person's 5).I wanted to test if pairwise comparison (1v1) could produce a cleaner, strictly relative dataset.Instead of asking "How beautiful is this person?", the system asks a simple question: "Who do you choose?". It uses a ranking system inspired by competitive games (Elo/Glicko) under the hood. As users vote, a global ranking emerges based on win/loss ratios against others rather than accumulated points.I'm curious about the "wisdom of the crowd" limits here. Does a pairwise sort actually converge on a clear consensus, or does it cycle indefinitely due to intransitive preferences (A > B, B > C, but C > A)?I'd love feedback on the ranking methodology and the overall UI.Dec 30, 2025 12:56 AM

Show HN: Interlock – Circuit breaker for AI infrastructure with signed auditshttps://news.ycombinator.com/item?id=46321932Interlock is a drop-in circuit breaker for AI systems (Express, FastAPI, core library) that tracks confidence, refuses low-certainty responses, and generates cryptographically signed certification artifacts and incident logs. It includes CI-driven stress tests, a certification badge, and reproducible benchmarks. Repo + quickstart: https://github.com/CULPRITCHAOS/InterlockWhat it doesTracks AI confidence, hazards, and triggers a reflex (refuse/degrade) rather than silently returning incorrect answers. Produces tamper-evident audit trails (HMAC-SHA256 signed badges, incident logs, validation artifacts). Ships middleware for Express and FastAPI; adapters for 6 vector DBs (Pinecone, FAISS, Weaviate, Milvus, LlamaIndex, LangChain). CI workflows to test, stress, benchmark, and auto-generate certification badges. Evidence artifacts are preserved and linkable.

20 years in Antarcticahttps://www.esa.int/Science_Exploration/Human_and_Robotic_Exploration/20_years_in_AntarcticaFor two decades, ESA has sent a medical doctor to brave the cold and more for 13 months at Concordia station in Antarctica, one of the most remote places on Earth. This unique environment – isolated, confined and extreme – mirrors many of the psychological and physiological challenges astronauts face in space. By studying life at Concordia, scientists can better understand these effects, develop countermeasures and prepare for future human missions beyond Earth.Dec 15, 2025 1:36 PM
