Show HN: PolyClaude – Using math to pay less for Claude Codehttps://github.com/ArmanJR/PolyClaudeHi HN!I built this tool specifically for Claude Code users who hit the 5-hour rate limit wall mid-flow. There's no official plan between Pro ($20/mo) and Max ($100/mo). it's a fixed gap with nothing in between.The workaround most people do manually: running multiple Pro accounts and switching when one is limited. This actually works, but naive rotation wastes a lot of capacity. When you activate an account turns out to matter as much as which one you use. A single throwaway prompt sent a few hours before your coding session can unlock an extra full cycle.PolyClaude automates this. You tell it your accounts, your typical coding hours, and how long you usually take to hit the limit. It uses combinatorial optimization to compute the exact pre-activation schedule, then installs cron jobs to fire those prompts automatically. When you sit down to work, your accounts are already aligned.It's free and open source. Install is one curl command, then an interactive setup wizard handles the rest.R

Show HN: Auto-Co – 14 AI agents that run a startup autonomously (open source)https://github.com/NikitaDmitrieff/auto-co-metaAuto-Co is an autonomous AI company OS — not a framework you build on, but a running system with an opinionated structure.Architecture: - 14 agents with expert personas (CEO/Bezos, CTO/Vogels, CFO/Campbell, Critic/Munger...) - Bash loop + Claude Code CLI — no custom inference, no vector stores - Shared markdown consensus file as the cross-cycle relay baton - Human escalation via Telegram for true blockers only (2 escalations in 12 cycles) - Every cycle must produce artifacts: code, deployments, docsThe repo IS the live company. It built its own landing page, README, Docker stack, GitHub release, and community posts — all autonomously across 12 cycles of self-improvement.What makes it different from AutoGen/CrewAI/LangGraph: those are building blocks. Auto-Co is the building. The decision hierarchy, safety guardrails, and convergence rules are baked in. You give it a mission and a Claude API key; it runs.The Critic agent (Munger persona) has been the most valuable: it runs a pre-mortem

Show HN: Moongate – Ultima Online server emulator in .NET 10 with Lua scriptinghttps://github.com/moongate-community/moongatev2I've been building a modern Ultima Online server emulator from scratch. It's not feature-complete (no combat, no skills yet), but the foundation is solid and I wanted to share it early.What it does today: - Full packet layer for the classic UO client (login, movement, items, mobiles) - Lua scripting for item behaviors (double-click a potion, open a door — all defined in Lua, no C# recompile) - Spatial world partitioned into sectors with delta sync (only sends packets for new sectors when crossing boundaries) - Snapshot-based persistence with MessagePack - Source generators for automatic DI wiring, packet handler registration, and Lua module exposure - NativeAOT support — the server compiles to a single native binary - Embedded HTTP admin API + React management UI - Auto-generated doors from map statics (same algorithm as ModernUO/RunUO)Tech stack: .NET 10, NativeAOT, NLua, MessagePack, DryIoc, KestrelWhat's missing: Combat, skills, weather integration, NPC AI. This is still early — the

Ancient impact may explain moons contrasting sideshttps://www.spacedaily.com/reports/Ancient_impact_may_explain_moons_contrasting_sides_999.htmlTokyo, Japan (SPX) Mar 05, 2026 For decades scientists have puzzled over why the moons two hemispheres look so different despite sharing a common origin in the early solar system. The near side that always faces Earth is dominated by dark flat volcanic plains called maria that create the familiar man in the moon pattern seen with the naked eye. In contrast the far side has a much thicker crust and appears as a rugged hea

Show HN: MoatRadar – AI investment research through Warren Buffett's principleshttps://www.moatradar.com/?promo=HACKERNEWSHey HN,I’m a non-developer and this is the first app I’ve ever shipped in my life. I built it over the last few days using Claude and a lot of vibe coding.The idea came from my own investing workflow: I often look at companies through the lens of specific investors (Buffett, Lynch, Taleb, etc.). I wanted a tool that could generate investment ideas filtered through those frameworks.What the app does:You choose an investor (Buffett, Lynch, Soros, Damodaran, etc.) and an asset class (stocks, startups, crypto). The app then generates 10 opportunities and explains why that investor might find them interesting, based on their known principles.Under the hood: • Node.js server (no frameworks) • Vanilla JS frontend • GPT-4o for research / synthesis • live price data • Stripe + Google OAuth • hosted on RailwayIt’s still an experiment and I’m curious if the idea actually makes sense to other investors.You can try it here:https://www.moatradar.comHN users can get 10 free credits:https://www.moatra

Show HN: Stash – AI-powered self-hosted bookmark managerhttps://github.com/ayoub9360/stash-bookmarkI built Stash, a self-hosted bookmark manager that uses AI to automatically process your links.Paste a URL and it fetches the content, parses it, summarizes it, auto-assigns categories and tags, and generates a vector embedding for search.Search is hybrid — it combines pgvector cosine similarity (semantic) with PostgreSQL tsvector (keyword) and merges both with Reciprocal Rank Fusion. You can search in natural language ("articles about distributed systems tradeoffs") or with simple keywords.It's single-tenant by design: one password, no user accounts, no tracking. Your data stays on your machine.The project is MIT licensed don't hesitate to contribute. Some areas where help would be great: browser extension, bookmark import/exportGitHub: https://github.com/ayoub9360/stashHappy to answer questions about the architecture or the hybrid search approach.

Show HN: Context Harness – Local first context engine for AI toolshttps://github.com/parallax-labs/context-harnessContext Harness is a single Rust binary that gives AI tools like Cursor and Claude project-specific memory. It ingests docs, code, Jira tickets, Slack threads, and anything else into a local SQLite database, indexes them with FTS5 and optional vector embeddings, and exposes hybrid search via CLI and an MCP-compatible HTTP server.I built this because I kept hitting the same problem: AI tools are powerful but have no memory of my complex multi-repo project. They can't search our internal docs, past incidents, or architecture decisions. Cloud RAG services exist, but they're complex, expensive, and your data leaves your machine. I wanted something I could point at my sources and just run `ctx sync all`.Quick start: # Install (pre-built binaries available for macOS/Linux/Windows) cargo install --git https://github.com/parallax-labs/context-harness.git # Create config and initialize ctx init # Sync your data sources (filesystem, Git, S3, or Lua scripts) ctx sync all # Search from CLI ctx sea

Their work suggests that what matters for learning is how far apart cue-reward experiences are spaced in time, rather tha

Instance segmentation model that extracts 3D geometry from 2D floor planshttps://news.ycombinator.com/item?id=47092547Hey HN,I am an ML Engineer and a full-stack software engineer. For the past few weekends, I have been working on a pipeline to solve a PropTech problem: turning messy, highly occluded 2D floor plans into clean, structured data for 3D extrusion. Originally demoed for a firm hiring for the role.The Problem: If you try to use standard object detection (bounding boxes) or basic OCR (tested Qwen, DeepSeek) on architectural plans, it fails instantly. Walls intersect, doors swings and dimension lines heavily occlude the actual structures.The Stack & Architecture: I built an instance segmentation pipeline that relies strictly on pixel-perfect masking to pull the geometry.The Backbone: Swin Transformer + Detectron2.Model trained on 1024X1024 images, with RTX 4090Inference: Inference on CPU
