In plain words
A fast 2D physics engine is a software tool for simulating physical interactions in two-dimensional environments. It is designed for developers and creators who need to build games, simulations, or interactive applications with realistic motion, collision detection, and force dynamics. The engine prioritizes performance, making it suitable for projects where computational efficiency matters. Available as open-source code on GitHub, it provides the core physics calculations needed to bring 2D worlds to life.

Almost eight years ago I launched an online “Linux sysadmin course for newbies” here at HN. It was a side-project that went well, but never generated enough money to allow me to fully commit to leaving the Day Job. After surviving the Big C, and getting made redundant I thought I might improve and relaunch it commercially – but my doctors are a pessimistic bunch, so it looked like I didn’t have the time.
