Ephemeral VMs in 1 Microsecond
In plain words
Ephemeral VMs in 1 Microsecond is a tool for developers and systems engineers who need to quickly spin up temporary virtual machines. It creates isolated VMs in microsecond timeframes, making it useful for testing, sandboxing, and rapid deployment scenarios. The project is open-source and available on GitHub, targeting users who require extreme speed in virtualization without the overhead of traditional VM startup times.

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:…
