Structured calisthenics progression for beginners

What it does

Most beginners quit calisthenics because they feel lost. CaliStack helps you understand what to train next using structured progression paths and skill-tree-based workouts. Instead of random exercises, the app guides you step by step from beginner movements to advanced skills like handstands and muscle-ups with workouts, tutorials, and progression systems built for real learning.

    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.
