TL;DR

This page is basically Hussein Nasser’s ultimate resource hub, kicking off with a deep dive into Virtual Memory Areas (VMAs) and page-faults (with a link to the full video). From there you’ve got an arsenal of courses—OS fundamentals, Node.js internals, backend troubleshooting, networking and database engineering, plus NGINX and Python on the backend—all neatly bundled with special coupon links.

Outside of the core tutorials, you’re invited to follow Hussein on Medium, join his YouTube membership (and member-only playlist), binge the Backend Engineering videos & podcast, and even support him with a virtual coffee. There’s also an Arabic software engineering channel and some affiliate tools for crafting slick slides and thumbnails. Enjoy!
