  LavinMQ, an open-source message broker written in CrystalApr 2026 · github.com · ▲16

  Hi HN. I'm Carl, creator of LavinMQ. LavinMQ is an open-source message broker. AMQP 0-9-1, MQTT, HTTP and streaming. Single binary, minimal resource use. If you know RabbitMQ, it's that (but running on a fraction of hardware). We're the team behind CloudAMQP where we've hosted RabbitMQ for 14 years. Sometimes customers hit issues we couldn't fully explain / work around. So we built our own broker, in order to provide solutions where we previously couldn't (which is much easier when you control the full stack). It all started by me building an open-source AMQP proxy to handle short-lived…

  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…
