  Statusduck – Website monitoring tool where the data is public2024 · statusduck.io · ▲78

  Hello HN! We're excited to share Statusduck, an uptime monitoring tool where the data is publicly viewable. There are an uncountable amount of uptime tools but we thought we'd put a fun spin on the concept by making another one where people can immediately set up a monitor without signing up. Just type in a website and our service will start pinging it every minute!

  I built a self-hosted status page and monitoring tool for my projects2024 · github.com · ▲103

  Hey HN! I'm excited to share Statusnook - a status page and monitoring tool. I built Statusnook for my own projects, but I soon began incorporating bits of feedback from friends & colleagues. My goal was to create a tool with a solid essential feature set, and to make it easy to self-host. I welcome any feedback or suggestions.

  Needle: We Distilled Gemini Tool Calling into a 26M Model▲776

  Hey HN, Henry here from Cactus. We open-sourced Needle, a 26M parameter function-calling (tool use) model. It runs at 6000 tok/s prefill and 1200 tok/s decode on consumer devices. We were always frustrated by the little effort made towards building agentic models that run on budget phones, so we conducted investigations that led to an observation: agentic experiences are built upon tool calling, and massive models are overkill for it. Tool calling is fundamentally retrieval-and-assembly (match query to tool name, extract argument values, emit JSON), not reasoning. Cross-attention…
