Sync vs Async IO

Hussein Nasser breaks down synchronous vs asynchronous I/O in a lively YouTube session (watch here: https://youtu.be/yGjGc21mmoU). Beyond that deep-dive, he’s basically built a one-stop shop for backend engineers: OS fundamentals, Node.js internals, performance troubleshooting, networking, databases, NGINX, Python—the list goes on, each with easy-to-use coupon links.

He’s also got you covered on the community front with a podcast, curated video playlists, a Medium membership, and YouTube channel perks (join, buy a coffee, members-only content). Plus, if you’re into slick slide designs, he’s partnered with Canva for that too. Stay awesome, friends!
