Io_uring for Ruby
In plain words
Io_uring for Ruby is a Ruby library that integrates Linux's io_uring interface into the language. It allows Ruby developers to perform high-performance asynchronous input/output operations on Linux systems. The library is designed for programmers building applications that require efficient handling of multiple concurrent I/O tasks. It stands out by bringing low-level kernel I/O capabilities to Ruby's ecosystem.

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:…
