- NANav – A terminal navigator for interactive `ls` workflows2023 · github.com · ▲75
Hi Everyone, I built a tool for interactive navigation in the terminal that is intended to replace the all-too-familiar cycle of `ls` to view a directory, followed by `cd`, then `ls`, and repeat. nav is a terminal filesystem explorer built for interactive `ls` workflows. The key features I wanted to enable are interactivity and search without feeling like I'm using anything other than `ls`. nav supports common `ls` options/flags, as well as tab completion, and might expand its support for less common options in the future. These options exist as both CLI flags and interactive toggles.…

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…
