Hi HN! I built a simple chess game so that my son in Singapore can play chess with his grandfather in China. Why? There is currently no service or open source software that has all of the following: * All processing and assets on a single server (Critical to workaround a firewall) * No email account required (Chinese Internet services typically login via WeChat) * Works on Android browser * Simple to install and config I built it, together with Claude Code, using simple and boring technologies (Django + Client-side JS). I hope that when you use it, you will find it simple to understand…

I made this basic website for my daughter (6) to learn how to move chess pieces. I wanted a simple game which didn't have all the rules, just how to get from A to B with a piece. Admittedly, as soon as I made this a friend pointed out https://lichess.org/learn which is really nice! There are a bunch of settings you can tweak to set the difficulty etc. Anyway, maybe will be a fun (short) diversion.

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…
