Virtual Memory Areas (VMAs) is the title of Hussein Nasser’s OS deep-dive page, which kicks off with the fundamentals of operating systems and Node.js internals—complete with a video on page faults and a Backend Troubleshooting course link. It’s an awesome primer if you want to understand how your machine handles memory and processes.
On top of that, Hussein lines up a feast of backend engineering resources: networking, database, Python, and NGINX courses (Udemy coupons included), a YouTube membership for exclusive content, a podcast, Medium posts, and even a buy-me-a-coffee link. And yes, all his slide decks and thumbnails get the Canva treatment—because pretty visuals never hurt.
