Error return traces for Go, inspired by Zig
In plain words
This is a Go library that provides error return tracing inspired by Zig's approach. It helps developers track and display error chains more effectively in Go applications. The tool is designed for Go programmers who want better error handling and debugging capabilities. It was launched in late 2023 and is available as an open-source project on GitHub.

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:…
