TL;DR

Hussein Nasser’s “The rule of CPU in the Kernel” page is basically a hub for all his backend-and-systems courses, from OS fundamentals and Node.js internals to networking, database engineering, NGINX, and Python on the backend. He’s also got a backend troubleshooting course, a full playlist of backend and database videos, plus a podcast for those who prefer audio.

Alongside the course links, you’ll find ways to support him—Medium membership, YouTube channel/join button, “buy me a coffee,” and affiliate gear recommendations (hello, Canva). There’s even an Arabic software engineering channel and members-only content for die-hard fans.
