Eigendrum - Draw any shape and hear what it sounds like as a drumAug 2026 · baselashraf81.github.io · ▲243Hi 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:…

Hey all My name is Sindre, and I am the CTO of Scrimba (YC S20). For the last 7 years, I have written all my web apps in a full-stack programming language called Imba. It compiles to JavaScript and its main goal is to make web developers more productive. I just launched a major overhaul of Imba, so I wanted to share it here on HN, in case anyone are interested in learning more about it. It is very opinionated, so some of you might not like it, but I would love to hear anyones feedback regardless. Constructive criticism appreciated! The backstory: Imba initially started in 2012 as an effort…

Hello HN, Over the last year we've been building ente[1], a privacy-friendly, easy-to-use alternative to Google Photos. We've so far built Android[2][3], iOS[4], web[5] apps that encrypt your files and back them up in the background. You can access these across your devices, and share them with other ente users, end-to-end encrypted. You can also use our electron app[6] to maintain a local copy of your backed up files. We've built a fault-tolerant data replication layer that replicates your data to two different storage providers in the EU. We will be providing additional replicas as an…
