ModResponse – Mock, modify, and replay HTTP response

In plain words

ModResponse is a Chrome extension that enables users to mock, modify, and replay HTTP responses. It allows developers to intercept and alter network responses during testing and debugging workflows. The tool is designed for developers who need to test application behavior without relying on live backend services or to simulate different response scenarios. It launched in June 2022.

  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:…

  A friend and I spent 6 years making a simulation game, finally released▲1,157

  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:…
