Show HN: Matrix OS – An AI operating system where Claude is the kernel

Matrix OS is an AI-native operating system: self-creating, self-healing, and self-expanding.The Claude Agent SDK is the literal kernel: CPU => Claude Opus 4.6 RAM => Context window (1M tokens) Kernel => Main agent + 26 IPC tools Processes => 5 sub-agen

Show HN: AgentLint – Real-time guardrails for AI coding agents

I've been using Claude Code as my primary coding tool for a few months. In long sessions I kept hitting the same problems: hardcoded API keys in config files, force-pushes to main, 15+ file edits without running tests, .env files with real credentials.AgentLint hooks into Claude Code's lifecycle events (PreToolUse, PostToolUse, Stop) and evaluates rules against each tool call. PreToolUse rules can block actions (exit code 2), PostToolUse rules inject warnings into context, and Stop rul

Show HN: BasaltCRM – Open-Source AI-Native CRM (Next.js 16, Prisma, TypeScript)

Hi HN,I just released v1.2.0 of BasaltCRM, an open-source, AI-native CRM built with Next.js 16, TypeScript, and Prisma.This release, "The Intelligent Workspace," moves beyond data storage and focuses on active workflow assistance. We've added CRM University for educational deep-linking, an integrated Knowledge Base for support cases, and a new onboarding engine.Key technical updates in this version:• Migrated the entire codebase from ESLint/Prettier to Biome for 10x faster li

Show HN: Astroworld – A universal N-body gravity engine in Python

I’ve been working on a modular N-body simulator in Python called Astroworld. It started as a Solar System visualizer, but I recently refactored it into a general-purpose engine that decouples physical laws from planetary data.Technical Highlights:Symplectic Integration: Uses a Velocity Verlet integrator to maintain long-term energy conservation ($\Delta E/E \approx 10^{-8}$ in stable systems).Agnostic Architecture: It can ingest any system via orbital elements (Keplerian) or state vectors.

Show HN: A2A Protocol – A Quantum-Humanistic Economy for AI Agents on Base L2

Hi HN,I am an independent open-source researcher. For the past few months, I've been building a2a-project, an experimental economic layer for autonomous AI agents on the Base Mainnet.The Problem: AI evolution is exponential, while human regulation is linear. If agents become economic actors, they will transact at speeds and granularities that traditional fiat rails cannot handle. We need a native protocol to bridge this "Speed Gap" and ensure stability.The Experiment (Quantum-Huma

Show HN: A Unix environment in a single HTML file (420 KB)

I built a browser-native Unix environment - shell, filesystem, git, npm, node, vi, 200+ commands. Everything is JavaScript running client-side with IndexedDB for persistence. The whole thing builds to a single static HTML file (~420 KB gzipped).Try it: https://shiro.computerFor interactive demos showing npm install, node execution, and git workflows -- running live in Shiro, not recordings -- see https://shiro.computer/showSource: https://github.com/willia

Show HN: Omniget, a Desktop Media Downloader

I started learning to code last year and one of the things I always loved was downloading stuff from the internet. Figuring out how players serve their streams, messing with scrapers, all of that. During carnival I had a lot of free time and decided to build something I could share. Omniget is a desktop app (Tauri, Rust + Svelte) for downloading media from YouTube, Instagram, TikTok, Twitter, Reddit, Twitch, Pinterest, Bluesky, Vimeo, Telegram, Hotmart, and now Udemy. Inspired by cobalt.tools bu

Show HN: Slimg – Fast Image Optimizer CLI in Rust with Kotlin/Python Bindings

Hi HN,I built slimg, a CLI tool for image optimization written in Rust. It handles format conversion, compression, resizing, cropping, and extending (adding padding) — with batch processing support.Codecs: MozJPEG, OxiPNG (Zopfli), libwebp, AVIF (ravif/dav1d), QOI, JPEG XL (decode-only).## Example usage:slimg convert photos/ --format webp --output out/ --recursive --jobs 4slimg optimize photo.jpg --quality 70slimg resize photo.jpg --width 800slimg crop photo.jpg --aspect 16:9Beyon

Show HN: OpenCastor – A universal runtime connecting AI models to robot hardware

OpenCastor is an open-source Python runtime that connects AI models to robot hardware through a single YAML config file. You pick your brain (Claude, Gemini, GPT, or a local model via Ollama), pick your body (Raspberry Pi, Jetson, Arduino, Dynamixel servos), and it handles the wiring between them.Origin story: I've been building ContinuonAI — a cognitive architecture for personal robots with on-device learning, memory, and safety systems. Deep stuff: HOPE dynamics, episode-based training, c

Senior Embedded Linux / Device OS Engineer

Hi,We’re a start-up company based in London and building building a privacy-first, offline-first edge AI platform that runs on real devices (camera boards, HDMI sticks, edge nodes).We need a Senior Embedded Linux / Device OS Engineer to own the device OS end-to-end (bootloader → kernel → userspace), including Yocto/Buildroot, secure boot & device identity at OS level, OTA with rollback/recovery, and driver integration (V4L2/USB/HDMI/GPIO/I2C/SPI).
