TL;DR

Hussein Nasser lays out a deep dive into “The rule of CPU in the Kernel” and then hooks you up with a suite of hands-on courses: OS fundamentals, Node.js internals, backend troubleshooting, networking, database engineering, NGINX, Python—and more.

He’s also serving up extra goodies on YouTube (members-only playlists), Medium articles, a Backend Engineering podcast, and even a “buy me a coffee” link plus affiliate design tools if you’re feeling generous. Enjoy the ride!
