Hey everyone, I just want to take a moment to thank you for the ongoing support over this past year. Your constructive criticism has genuinely helped me improve the format with each video, whether it's the pacing, jokes, the code walkthroughs, or how I explain complex concepts.
I've been continuously upgrading my setup and experimenting with new ideas, and I'd love to hear what you think about the new format.
Thanks everyone!
Now enjoy the video,

In this video Im gonna talk about how Quake 3's netcode changed gaming forever.
In 1999, id Software faced an impossible challenge: create a multiplayer-only arena shooter that runs smoothly on dial-up internet. The solution? Build a networking system so revolutionary that we're still using the same techniques 25+ years later.
This deep dive explores the legendary Quake 3 netcode - from snapshot systems and delta compression to client-side prediction and why they chose UDP over TCP. Every CS student should study this masterclass in fundamental engineering.

What we cover:
-The impossible triangle: bandwidth, latency, and reliability
-Potentially Visible Sets (PVS) for spatial optimization
-Delta compression and the elegant field table system
-Huffman compression tailored for game data
-Client-side prediction and living in your own timeline
-Interpolation/extrapolation for smooth visuals
-Why UDP beats TCP for real-time games
-The circular snapshot buffer approach
