TL;DR

Hussein Nasser’s “The rule of CPU in the Kernel” page is basically a one-stop shop for backend and operating-systems nerds. It kicks off with a nod to the Kernel/CPU deep dive and then floods you with links to everything from OS fundamentals and Node.js internals to backend troubleshooting, networking, database engineering, NGINX, and Python courses—most of which come with Udemy coupons or free videos.

Beyond courses, you’ll find his Medium profile, YouTube channel (including members-only playlists), a podcast on backend engineering, and even an affiliate shoutout for design tools like Canva. If you learn something, you can buy him a coffee or join as a YouTube member to keep the content flowing.
