I mixed selling t-shirts with a little bit of game theory2012 · getnifty.com · ▲171
I had this idea rolling around in my head for the last couple of years, and I finally decided to build the damned thing just to get idea relief. The backend is a typical LAMP stack with the Symfony2 framework backing the P. Varnish sits in front of all the Chef managed Linode boxes. The site will work without Javascript (up until the checkout), and the style degrades really nicely depending on your viewport (try it out by resizing your browser). I'm open to all comments and critiques, so let me hear them. And if you are into graphic t-shirts, here is a code for a Hacker News 20% discount:…

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:…
