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. Why it mattersMany systems log “success” when an LLM confidently hallucinates. Audit trails and refusal policies matter for safety, com

The Army’s contribution to joint space operationshttps://spacenews.com/the-armys-contribution-to-joint-space-operations/Recent analysis by Reeves in the Mitchell Institute’s “Charting a Path to Space Superiority: The Cross-Domain Imperative” identifies the need for centralized command and control (C2) of counterspace capabilities under U.S. Space Command to ensure unity of effort. However, Reeves’s critique of the United States Army’s development of counterspace capabilities fundamentally misunderstands the Army’s role […] The post The Army’s contribution to joint space operations appeared first on SpaceNews.

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.

Show HN: Hazbin Hotel OC Maker – Create Original Characters with AIhttps://aiocmaker.com/oc-maker/hazbin-hotel-oc-makerHi HNI built a Hazbin Hotel OC Maker, an AI-powered tool that helps fans create original characters (OCs) inspired by the Hazbin Hotel universe.As a fan myself, I noticed that many creators struggle to turn vague ideas into a complete OC — especially when it comes to personality, backstory, visual traits, and tone consistency with the Hazbin Hotel style. Most tools focus only on images or only on text, so I wanted to combine both into a single workflow.What it doesGenerates original Hazbin Hotel–style characters (not existing canon characters)Helps define:Name & demon typePersonality traitsBackstory & motivationsVisual description suitable for artists or AI image toolsDesigned for writers, roleplayers, and artistsWorks entirely in the browser, no setup requiredWhy I made itI’m building a broader AI OC creation platform, and this is one of the first focused generators aimed at a specific fandom.

Micro X ray method reads ancient meteorite impact scarshttps://www.spacedaily.com/reports/Micro_X_ray_method_reads_ancient_meteorite_impact_scars_999.htmlTokyo, Japan (SPX) Dec 14, 2025 Researchers from China, Canada, and Japan have established a quantitative method to read the impact histories recorded in enstatite chondrites using micro X ray diffraction measurements. Enstatite chondrites are rare meteorites that formed in highly reducing conditions close to the young Sun and are chemically similar to the material that built Earth, making them key samples for reconstructing e

ClipE96: We Left the Clipboard Unguarded for 40 Yearshttps://news.ycombinator.com/item?id=46051434In 1984, Apple shipped copy and paste. It was a miracle of usability—and architecturally broken from day one.Press Ctrl+C and the entire payload—bytes, formatting, metadata, embedded objects—dumps into a system buffer that any application can read. No auth. No logging. No revocation.The clipboard is a broadcast channel disguised as a convenience.The catastrophe: The clipboard is now the #1 data exfiltration vector in enterprise. 77% of knowledge workers paste corporate data into AI tools. Every paste bypasses your CASB, EDR, SIEM, and DLP. Your security stack guards the front door while users walk data out the side.The waste: 40 billion copy operations/day × ~100KB average = 4 exabytes of daily churn. RAM pressure, cloud sync, VM duplication—all unnecessary. Annualized: 83B kWh, 33M tons CO₂, $10B in energy costs. We're burning a small nation's power grid because nobody questioned whether copying a sentence needed to ship a document.The semantic lie: Copy and cut were always opposites,

Show HN: Memory System Hitting 80.1% Accuracy on LoCoMo (Built in 4.5 Months)https://github.com/vac-architector/VAC-Memory-SystemI’ve been working on an independent memory-retrieval architecture for agent systems. I don’t have a CS background — previously worked climbing cell towers and doing handyman jobs — but I spent the last 4.5 months building a hybrid memory system from scratch.The system combines FAISS, BM25, and a symbolic ranking layer (MCA). Answers are generated with GPT-4o-mini at temperature 0. The focus is determinism, transparency, and reproducibility rather than model size.On the official LoCoMo benchmark (1,540 questions), the system reaches 80.1% average accuracy. To my knowledge, that’s above the publicly reported results for existing agent-memory stacks using small models.Latency is ~2.5 seconds, and cost is ~$0.10 per 1M tokens. Memory is fully isolated and local, which makes it usable for offline or enterprise applications.Repository (code + full reproducible benchmarking): https://github.com/vac-architector/VAC-Memory-SystemHappy to answer technical questions, discuss the architecture, or
