Virtual Memory Areas (VMAs)

Hussein Nasser’s page on VMAs doubles as a one‐stop shop for all things systems and backend: from OS fundamentals to Node.js internals, page‐fault deep dives, backend engineering, networking, databases, NGINX and Python courses—most with Udemy coupons or custom domains.

On top of those tutorials, you’ll find his Medium and YouTube memberships, an Arabic channel, a Backend Engineering podcast, and even a “buy me a coffee” link. Plus, all his slide and thumbnail design magic is powered by Canva.
