fffocus – a simple tool that helps you clear your mind before work
The url can be found in the first comment. To scratch my own itch, I created a simple tool that should be helpful to many of us who are under constant distractions. If anyone uses this and finds it effective or ineffective, please kindly share your experience. Below are some ways I think it can be put in use: 1. Before we start a work day, we can use it to clear up random thoughts and anxiousness. 2. We can use it regularly to increase our attention span. Note: This was posted several years ago. I only made very minor changes since last time. I'm reposting it and hope to see some feedback on…

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.
