Autogenerate Playwright and Puppeteer test scripts from the browser
In plain words
Deploy Sentinel automatically generates test scripts for Playwright and Puppeteer by recording browser interactions. The tool captures user actions in a web browser and converts them into executable test code, eliminating manual script writing. It's designed for developers and QA engineers who need to create automated tests quickly. The main advantage is reducing the time spent writing test scripts by hand while ensuring tests accurately reflect actual user workflows.

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:…
