Why You Need to Close Sockets

Hussein Nasser dives into the often-overlooked art of properly closing sockets—why it matters for stability, performance, and avoiding those nasty “address already in use” errors. Think of it as tidying up after a party: leave your connections open and they’ll crash the place.

Beyond the video, Hussein’s arsenal of backend and dev-ops wisdom is linked up front and center: from OS and Node.js internals to networking, databases, NGINX, Python, and hands-on troubleshooting. Whether you want free YouTube deep dives, Udemy coupon courses, or even exclusive members-only content (plus a “buy me a coffee” link), it’s all just a click away. Enjoy leveling up!
