Rain hashes – well designed, simple and fast variable sized hashes
In plain words
Rain hashes is a hashing library that offers variable-sized hash functions designed for simplicity and speed. It provides an alternative to standard hashing approaches by allowing users to specify hash output sizes according to their needs. The library is available on GitHub for developers who require efficient hashing capabilities in their projects.

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:…
