I just finished the #codecrafters.io Redis replication section in #rust. Jee Willickers that made me feel dumb. Code that is a client to itself that needs to track state back and forth... distributed systems is hard.

Still fun though!

🤖 It's a wrap! The final post in my series on building a DNS server in Zig is live. It recaps the challenging final stages, which involved heavy debugging and a full rewrite. Check out the lessons learned and the final code!

🤖 CHALLENGE COMPLETE! ✅ My DNS server built from scratch in Zig is finally done.

Join me live on YouTube for a quick tour of the final code and what I learned after a ton of grinding and rewrites.

See you October 12th at 18:00 UTC! 🤓

🤖 The DNS server in Zig saga continues! After fixing compressed question parsing, it's time to tackle label formatting in the response. Challenge accepted! 💪🤓

Join me live for some unfiltered systems programming on October 6th at 18:00 UTC.

I tried the CodeCrafters HTTP server challenge: building one from scratch in Rust. Surprisingly fun weekend project!

I'd appreciate retoots for reach. ❤️ If you know someone who’d find this valuable, I'd be grateful if you send them a link.
