Why you need to close sockets – TL;DR

Hussein Nasser’s page isn’t an article so much as a treasure map for backend buffs: he’s rounded up everything from Operating Systems and Node.js internals to Networking, Database, NGINX and Python backend courses (most with Udemy coupons) plus a deep-dive Backend Troubleshooting series—all hosted across his personal sites and YouTube.

Beyond the courses you’ll find links to his Medium, Arabic engineering channel, podcast, and even a “buy me a coffee” link (plus Canva for slide and thumbnail design). Basically, if you want to level up your server-side game or support Hussein’s content, here’s your one-stop shop.
