NASA Laser Reflecting Instrument Makes GPS Satellite More AccurateA NASA laser reflecting technology that will aid Global Positioning System (GPS) accuracy is now operational as of March 9. The instrument, known as a laser retroreflector array, or LRA, launched aboard GPS III SV-09, the ninth of U.S. Space Force’s Block III Global Positioning System satellites, on Jan. 27. LRAs are sets of mirrors […]

Show HN: OpenClix, Agent friendly, open-source retention toolingHi HN,I’m sharing OpenClix, an open source toolkit for running mobile engagement and retention flows directly inside your app.The motivation came from repeatedly seeing the same pattern when teams try to improve retention. They end up stitching together push providers, experimentation tools, analytics pipelines, and backend services just to ship simple onboarding nudges or re engagement reminders. The setup becomes complex very quickly.OpenClix takes a different approach.Instead of a hosted platform or heavy SDK, it provides config driven engagement logic that runs on device. Campaigns and rules live in a simple JSON config and react to app events locally. You can trigger notifications, schedule follow ups, or suppress messages based on user behavior without needing a backend control plane.A few core ideas behind the project:• Local first execution. Engagement logic runs on the device, which removes a lot of infrastructure and latency. • Source vendoring instead of SDK lock in. The cod

Show HN: Tswap–Yubikey-backed secret injection for IaC and AI-assisted workflowsI built tswap after noticing that Claude Code, while genuinely useful for managing a Kubernetes cluster, was pulling plaintext secrets from every manifest it touched. I wanted the AI to be able to do its job without ever seeing the actual values.tswap keeps secrets in an AES-encrypted vault file on disk. The decryption key is derived from a YubiKey via HMAC challenge-response. At init you pair two YubiKeys — either unlocks the vault, so you have no single point of hardware failure.Config files use a comment-based placeholder that keeps them valid YAML: stringData: DB_PASSWORD: # tswap: db-password Deployment is a pipe: tswap apply values.yaml | helm upgrade myapp ./chart -f - The privilege split is the key design decision: `apply`, `run`, and `check` need no elevation (AI agent gets these). `get`, `list`, `delete`, and `export` require sudo/admin (human gets these). The AI can deploy; it can't read or enumerate secrets.Other features: burn tracking for rotation, `redact` for stripping

When a Platform Stops Saying "Automation" and Starts Saying "LLM"Enforcement Risk Dossier | PlatformPolicy Risk Brief… On January 20, 2026, eBay did not launch a feature. It revised a clause that governs access. Previous language prohibited “automated means.” Updated language (binding February 20, 2026) explicitly names: “buy-for-me agents, LLM-driven bots, or any end-to-end flow that attempts to place orders without human review…” That parenthetical is the structural shift. AI agents moved from implied coverage to explicit contractual identity. What was once broad and interpretive became specific and enforceable. When categories are named, interpretive space narrows. Narrower interpretation reduces enforcement latency. Reduced latency expands unilateral control over the access layer. … From Technical Signal to Contractual Codification December 2025: eBay robots.txt prohibited the same AI categories. Bots from named AI companies were restricted; selected integrations retained access.Sequence: Technical constraint -> Named AI blocking -> Contractual

Scaling rules for metamaterials promise better implants and safer devicesBerlin, Germany (SPX) Feb 04, 2026 Metamaterials are engineered composites whose internal architecture, rather than their base substances, governs how they respond to forces and deformation. In these systems, repeating building blocks known as unit cells are arranged in regular patterns, and their size, shape, and connectivity determine properties such as stiffness, strength, and energy absorption.
