I built a web app for learning Vim from the browser as a 17-year-old
Hey HN! After my own experiences with learning Vim, I wanted to skip the frustrating process of configuring a new tool before even learning how to use it. In an attempt to solve this problem, I started working on Vim Ninja, a web app that would allow developers to learn Vim through interactive lessons in the browser. It’s been a couple of months, and I’m proud to say that I’ve finally released https://VimNinja.com! Check out a demo of the app here: https://youtu.be/reukQHKqMZE.

In plain words
Vim Ninja is a browser-based learning platform that teaches the Vim text editor through interactive lessons, eliminating the need to configure the tool before learning it. Built with SvelteKit and Tailwind, the app provides an in-browser editor where developers can practice Vim commands directly. It targets people new to Vim who want to skip the setup frustration and jump straight into learning the editor's core functionality through hands-on exercises.

Hey HN! After my own experiences with learning Vim, I wanted to skip the frustrating process of configuring a new tool before even learning how to use it. In an attempt to solve this problem, I started working on Vim Ninja, a web app that would allow developers to learn Vim through interactive lessons in the browser. It’s been a couple of months, and I’m proud to say that I’ve finally released https://VimNinja.com! Check out a demo of the app here: https://youtu.be/reukQHKqMZE. On the technical side of things, I used SvelteKit to build the entire app and Tailwind, which turned out to be an amazing decision. I actually really like SvelteKit’s filesystem-based router as well as Svelte’s brevity, and Tailwind actually makes styling a fun task for me. I’m using CodeMirror 6 as a base for Vim Ninja’s code editor, and I really prefer it over more feature-packed alternatives like the Monaco Editor, which is what I started out with but soon abandoned due to its worse performance when compared to alternatives like CM6 and the sheer amount of bells and whistles that I just didn’t need.

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:…
