Show HN: Rebuno - An open-source runtime for production agents I have been building Rebuno, an open-source execution runtime for operating AI agents in production. It manages execution state and guardrails across agents built with different frameworks. Agents run as HTTP services. Rebuno dispatches work through signed webhooks and keeps execution state in Postgres. Agents submit tool and model calls to Rebuno as steps before executing them. For each new step, Rebuno evaluates per-agent YAML policies, independently of the model's prompt. It can allow the call, deny it, or hold it for human approval. The agent executes permitted calls and reports their outcomes. Policy decisions and step outcomes are both recorded in one append-only event log. After an interruption, the agent starts its handler from the top. Steps with recorded outcomes return those outcomes instead of executing again. A crash can also leave a tool with no recorded outcome. Tools marked safe_to_retry run again, and t...

Show HN: I made an automated day-by-day itinerary organizer for my trip to Spain For my solo food pilgrimage to the Basque Country, I pre-arranged flights in/out of Bilbao, Guggenheim Museum tickets, Michelin Guide restaurant reservations, bus tickets to San Sebastian and Saint-Jean-de-Luz, walking food tours and hotel reservations in each city, and a long list of pintxo spots to hit with notes on each one's food specialty. Most of this was poorly organized (manually) in my phone's Notes app, with references to specific emails for more information. I arrived on the first day in Bilbao, and the hotel didn't have me in their system by name, so I spent a good 10 minutes frantically scouring my emails for the confirmation number, cursing myself for holding up the people behind me. Over the course of the next few days, while I was relaxing at my hotel (after finally getting in) in between pre-planned stops, I started building a personal tool that would organize all of my booking...

Show HN: VibeWorld – a shared terminal world for developers and scientists Vibeworld is a persistent cyberpunk shared world that runs in your terminal, where you can meet other developers and scientists to have company at 2 AM while screaming at your LLM :) you can connect with other scientist, chat, and includes also use vocal chat if you want to use it. There is a world and a moon, and they are completely 3D rendered and animated. In the moon there is the "complaint crater": a place where you can scream an insult against your claude or codex session and everybody from the space can see it. You can create your pixel avatar! There is also the "stargazing ledge": a place where you can see the stars and whatever happens in the sky. You can chat in the meantime if someone else is there too, or just watch our Earth. Sometimes you can see galactic wars, and there is a plant that grows but dies if nobody waters it. You can leave it on the second monitor while working (it...

Show HN: Simpleboot and Easyboot These are FLOSS boot loaders and disk utilities which follow the suckless philosophy ( https://ift.tt/2pWjAOB ). Despite being totally dependency-free, they come with a fully featured single command to create bootable disk images out of a directory (utility is available on Windows, Linux and other POSIX systems). Usage is as simple as it gets. There are two repositories, depending on the desired use case: Simpleboot is the little brother, an embeddable boot loader: https://ift.tt/A1n3KlP - multiplatform (BIOS, UEFI, RPi, coreboot) - very small (less than 64k), single binary - also flashable into ROM (option ROM, expansion ROM, coreboot payload, etc.) - easy to configure (single config file, checked for validity by the disk creator utility) - one backup boot option - capable to boot Linux and simplified Multiboot2 kernels (see below) Easyboot is the big brother, an interactive boot manager: https://ift.tt/JoqxhH9 - multiplatform (BIOS, UEFI, RPi) - i...

Show HN: Lynen – A mobile app that tells you what clothes are made from Hi HN, I'm Chinedu, the creator of Lynen I built this because I got tired of buying clothes and having the seams pull out after the first wash or purchasing garments that said 100% cotton and turns out there is some polyester or toxic dye in the composition. Key Features 1. Mobile App - You can take this with you anywhere. 2. Scan or Search - Scan or manually look garment barcode and get lab verified fabric and chemical composition of your garment, as well as a durability result. 3. Personalization - A virtual assistant that provides tailored analysis from your skin notes. Helps makes better decisions when shopping. Tech Stack Built this using Next.js, React with TypeScript & TailwindCSS for styling, and Supabase for database Why I'm Posting Now I'm building a waitlist for the app launch which is in the coming days. I would love to build some traction before that happens. https://www.lynen.app Septe...
