I rewrote my 2012 self-signed cert generator in Go – cert-depot.comApr 2026 · ▲9
Back in 2012 I built https://cert-depot.com as a weekend project. Node.js + Express + jQuery, shelling out to OpenSSL for certificate generation. It worked but I eventually let it rot. https://news.ycombinator.com/item?id=4766743 Rewrote it from scratch in Go. The entire thing is a single binary with no external dependencies: 1. Certificate generation uses Go's crypto/x509 (no OpenSSL) 2. Certificates are generated in memory and streamed directly — nothing is stored on the server 3. RSA 2048/4096 and ECDSA P-256/P-384 4.

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:…
