I just sent out my 100th issue of Hacker Newsletter and announced my newest newsletter: Wayback Letter - http://www.waybackletter.com/ In either a daily or weekly version, you'll get links to great HN articles from the past five years. A great way to see how HN has grown and changed, plus see what was going on at different times. Lastly, there are a ton of great reads to learn from that I never saw the first go around. Would love to get feedback and my goal is to expand this past HN in the future.

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:…
