In “The rule of CPU in the Kernel,” Hussein Nasser covers a ton of backend topics—OS fundamentals, Node.js internals, troubleshooting, networking, databases, NGINX, and Python—through free YouTube videos, Udemy courses with coupons, and handy playlists that take you from the basics up to real-world performance tuning.

He also runs a podcast, writes on Medium, hosts members-only and Arabic-language channels, and even offers a “buy me a coffee” link and a Canva affiliate for designing slick slides and thumbnails. Perfect if you want to level up your backend game (or just support a cool creator).
