Firefox extension to obfuscate web page text
Sometimes you might want to share a screenshot of the website you're on, without revealing the personal data that is visible at that time. With Obfuscate, you can make text unreadable without changing the structure of the web page. Hit the extension button or press Alt+Shift+O to activate for the current page. (Note that extensions can't modify the add-on website, so trying it on there won't work.) Credit for the original idea: https://chaos.social/@maris/108379386421123630
In plain words
Obfuscate is a Firefox extension that renders text unreadable on web pages while preserving the layout, allowing users to share screenshots without exposing personal data. Activated via the extension button or Alt+Shift+O keyboard shortcut, it's designed for anyone who needs to obscure sensitive information before capturing or sharing web content. The tool maintains the visual structure of the page while making all text illegible.

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:…

I've seen some interests in (simulation) video games here on HN so I thought I'd share a short version of our story. More than 6 years ago, me and my friend from university were playing around with an idea of making a game we always wanted to play. We worked on it on weekends but the progress was quite slow, especially due to so many dead ends and wasted effort. Eventually however, we solidified our direction and decided to take the risk to resign from our well paid SWE jobs and work on it full time. It took more than a year but yesterday we have finally released it on Steam:…
