Sled-X
3) “Light‑powered ice sled that transforms every rink
What it does
S‑ledX is a next‑generation illuminated polycarbonate ice sled designed to transform the way people experience sledding. We wanted to rethink the entire category — not by adding complexity, but by elevating the essentials: safety, visibility, durability and pure enjoyment. S‑ledX is the result of that mission: a lightweight, impact‑resistant, LED‑powered sled that brings a new level of clarity, confidence and excitement to the ice.

I'm working on a GPS track visualizer for quite some time. It shines in hilly and mountaineous terrain (where a 3D view makes more sense), but it also offers quite a lot of Strava-like features (statistics etc.). You can upload your GPX and FIT files manually, or sync directly with Garmin, Coros and Polar. See https://cubetrek.com for the live app and check out some examples there. It's free and opens source. Also, anyone who likes to work with 3D visualizations (especially Babylon.js), let me know if you like to help polish this thing further.

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…
