Summary

This page, cheekily titled “What is Virtual Memory?”, actually serves as a one-stop shop for Hussein Nasser’s backend and systems content. It starts by linking to a YouTube deep dive on page faults and then lays out a buffet of courses—OS fundamentals, Node.js internals, backend troubleshooting, networking, databases, NGINX, Python on the backend, and more—along with his Medium articles and a buy-me-a-coffee link.

Beyond that, you’ll find invites to join his YouTube membership, an Arabic software engineering channel, members-only playlists, a backend engineering podcast, and even affiliate tools (like Canva for slides and thumbnails). If you wanted to learn about virtual memory, the video’s your best bet; otherwise, it’s a handy directory of backend resources.
