Undead – scary fast, bewitching web pages on the JVM with no JavaScript

Hey HN. I wrote a LiveView implementation for the JVM called Undead. (The name Undead is a play on the "Live" part of LiveViews.) I had been waiting for the new StringTemplates feature of Java 21 which made it scary-easy to get the right data structures to make things work. It's been enchanting to write Java after about ten years in Javascript and Go lands. Would love folks to try it out and lmk what you think. If you aren't too scared that is. ;)

In plain words

Undead is a LiveView implementation for the Java Virtual Machine that enables dynamic web pages without JavaScript. Built using Java 21's StringTemplates feature, it allows developers to create interactive web interfaces directly on the JVM. The tool is designed for Java developers seeking to build real-time web applications while staying within the Java ecosystem, offering an alternative to JavaScript-based frontend frameworks.

Eigendrum - Draw any shape and hear what it sounds like as a drum▲243
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:…
