    Refractify – Optical software against myopia2024 · refractify.io · ▲174

    Last summer there was an Ask HN[1] about a Nature article that said bluring the blue and green color channels on screen may be good against early myopia development. The OP wanted such software and there was none available. So I quit my job and implemented this software, did a short video with a 3D artist about it. Turns out marketing is expensive, so I made an open source browser extension version too. How it works? There is a small neural network on the retina that tries to detect if the eye is far-sighted(most people are born far-sighted), and it is producing dopamine to slow or increase…

  • 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…
