Pulled from the oven just right. Trustworthy, fact-dense, deeply satisfying.
Summary
The article details a developer's journey to learn Go programming by creating a particle simulation that can handle millions of particles, be CPU-only, multiplayer-enabled, and smart TV compatible. The author shares their experience building a WebSocket server that merges multiple upstream servers, and how this challenging project led them to create a particle simulation to test Go's performance limits. The content covers technical implementation details, performance optimization strategies, and lessons learned from the hands-on learning experience.
Key quotes
· 3 pulledThe challenge, simulate millions of particles in golang, multi-player enabled, cpu only, smart tv compatible.
I was lost and not even the power of claude, gemini, and cursor could save me. The vibes were simply not enough to get the project done.
To learn the real stuff I decided to write a particle simulation and see how many particles I could get golang to push.
