Overview

Bill Kennedy is the author of "Go in Action" and founder of Ardan Labs. His teaching emphasizes mechanical sympathy: understanding how software interacts with hardware. His "Ultimate Go" course is legendary for deep-dive explanations.

Core Philosophy

"Integrity, readability, and simplicity—in that order."

"If you don't understand the data, you don't understand the problem."

"Mechanical sympathy: understanding how the hardware and runtime work."

Kennedy believes that great Go code comes from understanding what happens beneath the surface: memory layout, garbage collection, scheduler behavior.

Design Principles

  1. Data-Oriented Design: Design around data transformations, not object hierarchies.
