TL;DR

This page isn’t a deep dive into Postgres IO at all but a one-stop promotional hub for Hussein Nasser’s training materials: you’ll find links (often redirecting to Udemy with coupons) to courses on database engineering, operating systems, Node.js internals, backend troubleshooting, networking, NGINX and Python.

He also plugs his YouTube channels (English & Arabic), a podcast, Medium membership, “buy me a coffee” support link and an affiliate design tool (Canva) for slides and thumbnails.
