What it does
Semantic CLI tool for process management. Target by port, process id (PID), name or path. proc on :3000 # what's on port 3000? proc for/script.py # what's running this file? proc by node --in --min-cpu 5 # node in cwd using >5% CPU proc kill :3000,:8080,node # kill mixed targets at once proc info :3000,1234 # info for port + PID

Hi HN, I built a small Linux CLI tool called witr (Why Is This Running?). The idea came from a situation most of us have hit: you log into a machine, see a process or port running, and immediately wonder why it exists, who started it, and what is keeping it alive right now. witr traces a process, service, or port back to its origin and responsibility chain and explains it in a way that’s quick to read, especially when you’re debugging under pressure. This is v0.1.0. It’s intentionally small and focused. Feedback, criticism, and edge cases are very welcome. Repo:…

- RARun – a CLI universal code runner I built while learning RustOct 2025 · github.com · ▲96
Hi HN — I’m learning Rust and decided to build a universal CLI for running code in many languages. The tool, Run, aims to be a single, minimal dependency utility for: running one-off snippets (from CLI flags), running files, reading and executing piped stdin, and providing language-specific REPLs that you can switch between interactively. I designed it to support both interpreted languages (Python, JS, Ruby, etc.) and compiled languages (Rust, Go, C/C++). It detects languages from flags or file extensions, can compile temporary files for compiled languages, and exposes a unified REPL…

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…
