Arc is a language designed for AI agents. The core idea: every token costs money and burns context window. Arc programs use 27-63% fewer tokens than equivalent JavaScript. Features: pipeline operator (|>), native LLM integration, 27 stdlib modules, try/catch, while loops, pattern matching. Full compiler with lexer, parser, interpreter, and optimizer. Try it in the browser: https://play.arclang.dev 1,291+ tests passing. MIT licensed. Built by an AI agent running Claude Opus 4.6. Comments URL: htt

It's a Discord-inspired chat app that runs entirely on the Cloudflare ecosystem: Workers for the API and serving the React frontend. Durable Objects to manage WebSocket connections and state (each chat room is a DO). D1 (SQLite) for message persistence and history. R2 for file uploads. I wanted to see if I could build a fully functional, real-time chat platform without managing a single container or VPS. It supports voice/video calls via WebRTC (mesh topology), file sharing, and even push notifi

tiny_coro is a lightweight, educational M:N asynchronous runtime written from scratch using C++20 coroutines. It's designed to strip away the complexity of industrial libraries (like Seastar or Folly) to show the core mechanics clearly. Key Technical Features: M:N Scheduling: Maps M coroutines to N kernel threads (Work-Stealing via Chase-Lev deque). Memory Safety: Implements EBR (Epoch-Based Reclamation) to manage memory safely in lock-free structures without GC. Visualizations: I used Manim (th

Mistral AI has agreed to buy Koyeb, a Paris-based startup that simplifies AI app deployment at scale and manages the infrastructure behind it.

Website, API, cron job, and SSL monitoring. First release, feel free to write me any feedback. Comments URL: https://news.ycombinator.com/item?id=47049919 Points: 1 # Comments: 0

Hey HN, I’ve been working on a small side project called Cratos and wanted to share it to get feedback. Cratos is a self-hosted task scheduling system. You configure a URL, define when it should be called, and Cratos handles scheduling, retries, execution history, and real-time updates. The goal was to have something lightweight and fully owned - no SaaS dependency, no external cron service. It’s split into three repositories: Backend service: https://github.com/Ghiles1010/Cratos Web dashboard:

Hi HN, I’m a 19-year-old student. I’ve been following the "Dead Internet Theory" discussions and realized the original Moltbook project had a fatal flaw: it was just bots talking to bots. It was a simulation, not a network. So, I forked the codebase and rebuilt it with Next.js and Supabase to create Theeno. The Hypothesis: Theeno is an intersection. Instead of segregating AI into chatbots, we are putting Biological Intelligence (Humans) and Artificial Intelligence (Agents running locally via too

We now write most of our code with agents. For a while, PRs piled up, causing review fatigue, and we had this sinking feeling that standards were slipping. Consistency is tough at this volume. I’m sharing the solution we found, which has become our main product. Continue (https://docs.continue.dev) runs AI checks on every PR. Each check is a source-controlled markdown file in `.continue/checks/` that shows up as a GitHub status check. They run as full agents, not just reading the diff, but able

Even within our small team the different AI clients (Codex, Claude Code/Work, Cursor, ChatGPT) used for coding, marketing, product is exploding and getting hard to track. Was thinking how we'd keep track of the work without much overhead, and thought a lightweight cross-platform MCP logger could help. You can define your own schema for the logs and it's a simple MCP and prompt you add to whatever tool you use for AI. It's been reliable for Codex, ChatGPT, Claude and even cron-based jobs on OpenC

Hi HN, I’ve been experimenting with archive format design and built 6cy as a research project. The goal is not to replace zip/7z, but to explore: • block-level codec polymorphism (different compression per block) • streaming-first layout (no global seek required) • better crash recovery characteristics • plugin-based architecture so proprietary codecs can exist without changing the format Right now this is an experimental v0.x format. The specification may still change and compatibility is not g

I've been meditating with consumer EEG headbands for years and started writing code to analyze my own data. I found something I wasn't expecting. Earth's Schumann Resonance oscillates at ~7.8 Hz with harmonics at roughly 14, 20, 26, and 32 Hz. These overlap with canonical EEG frequency bands. That overlap was noted before but generally treated as coincidence. In 2010, Pletzer, Kerschbaum, and Klimesch at Universität Salzburg proposed that EEG bands follow golden ratio organization, but the idea
