Hussein Nasser’s page titled “The state of Direct IO in Postgres” is really a roundup of his favorite learning resources—from OS fundamentals and Node.js internals to backend troubleshooting, networking, database engineering, NGINX, and Python courses (many with Udemy coupons).
Beyond video playlists and a Backend Engineering podcast, he also plugs his Medium membership, YouTube channels (including an Arabic software engineering one), a members-only playlist, and affiliate tools like Canva—plus a cheeky “buy me a coffee” link to keep the content coming.
