Tracexec – TUI for tracing execve and pre-exec behavior
tracexec helps you to figure out what and how programs get executed when you execute a command. It's useful for debugging build systems, catching fd leaks, understanding what shell scripts actually do, figuring out what programs does a proprietary software run, etc.
In plain words
Tracexec is a terminal user interface tool that traces program execution and pre-execution behavior to show what commands and processes run when a user executes code. It helps developers debug build systems, identify file descriptor leaks, understand shell script behavior, and discover what programs proprietary software launches. The tool is particularly useful for anyone needing visibility into the execution chain of complex commands or scripts.

Hi HN, I built Eigendrum, a web tool that solves the 2D wave equation for arbitrary shapes so you can hear what they sound like as drums. How it works: * Solves -∇²u = λu using finite element analysis (Kφ = λMφ) on a triangle mesh. * Validated to <0.1% error against closed-form solutions for circles (Bessel zeros) and rectangles. * Sound model factors in strike location, Rayleigh damping, and mallet width. * Includes Kac drums I & II to demonstrate identical sound spectra from different geometries. * No frameworks, build steps, or dependencies. Repo and tests:…
