Systems & Theory

What a computer really is, how it runs, and the limits of what it can do.

Build the core

Get your hands on the real mechanism.

Proofs, logic, and the astonishing fact that some problems can NEVER be solved by any computer, ever.

Why one way of solving a problem finishes in a second and another would outlast the universe.

What's really happening beneath your code: bits, memory, and how C becomes electricity.

How one computer juggles hundreds of programs at once without letting them trample each other.

The hidden web connecting people, web pages, and neurons, and the simple rules that govern how things spread.

Reach the summit

The graduate-level frontier.

How thousands of computers across the planet cooperate to act like one: the backbone of the internet and the cloud.

Why chips got fast (pipelines, caches, and parallelism) and why your code's speed depends on the silicon.

The math that keeps secrets: how your messages stay private even when everyone can see them go by.
