Dennis Gustafsson, creator of Teardown, presents how he parallelized the physics solver for an upcoming game, followed by a Q&A. The talk was given at the Better Software Conference 2025.
Why Hacker News recommends it
HN points to it as a practical example of solving a tricky multithreading problem, including using a spinlock to speed up a real-time physics solver.

As always: use standard libraries, profile, then write your own if the data indicates it's necessary.

From my understanding this talk describes how he implemented a solution for a similar problem ▶ this video I'm saying if you're not writing multi-threaded code everyday, use a library. It can use atomics/locks but you shouldn't use it directly. If the library is designed well it'd be impossible to deadlock.
