Hussein Nasser’s “Why you need to close sockets” page isn’t really an in-depth article but a hub of his backend-engineering goodies: from OS fundamentals, Node.js internals and backend troubleshooting to networking, database engineering, NGINX and Python courses (many with Udemy coupons).
He also invites you to follow him on Medium, join his YouTube channel (and get members-only content), tune into his backend podcast, and even buy him a coffee—plus a peek at his go-to design tools via affiliate links.
