No vacation policy.

No expense policy.

No approval process.

Just one rule: Act in Netflix’s best interest.

In 2009, Netflix published a culture deck that became legendary. Sheryl Sandberg called it “the most important document ever to come out of Silicon Valley.”

It laid out a radical philosophy:

Give people freedom. Expect extraordinary results. Fire quickly if they don’t deliver.

It’s provocative. Some love it. Some hate it. But everyone talks about it.

Data-Oriented Design: Implementing ECS (Entity Component System) with Go Generics

Mon, 08 Jul 2024 00:00:00 +0000

From Object-Oriented to Data-Oriented

Traditional object-oriented programming (OOP) encourages you to model game entities as objects with inheritance hierarchies. While intuitive, this approach leads to poor cache locality, rigid hierarchies, and performance bottlenecks. Data-oriented design, particularly the Entity Component System (ECS) pattern, flips this on its head.

With Go 1.18+ generics, we can now build type-safe ECS architectures that deliver both performance and flexibility. Let me show you how.

The OOP Problem

Here’s the typical OOP approach to game entities:

You snap out of it and realize: you were completely immersed. Time disappeared. Effort felt effortless. You were operating at a level you rarely achieve.
