Virtual Memory Areas (VMAs)

Hussein Nasser’s page kicks off with a look at VMAs but really serves up a treasure trove of backend and systems-engineering goodies: OS fundamentals, Node.js internals, a deep dive on page faults, backend troubleshooting, networking, database engineering, NGINX and Python courses—with Udemy coupons where available.

Beyond courses, you’ll find links to his Medium membership, YouTube channel (including members-only content), a backend engineering podcast, and even a “buy me a coffee” donation page. Also sprinkled in are affiliate tools like Canva for slides and thumbnails.
