In this live series, I’m rebuilding my entire NixOS system configuration from the ground up. This setup powers my daily driver laptop, backup machine, and a network of self-hosted servers I've used every day for a few years now. I’ll walk through how everything fits together, what I’ve learned so far, and how I plan to evolve it over time. Enough with procrastination, I'm ready to finalize my server setup for: 1. Main edge server for blog, Plausible, pihole, and n8n. 2. Monitoring node (Raspberry Pi 4) with Grafana and Prometheus. 3. Network service node (Raspberry Pi 5) with Searx, and a redundancy instance of pihole. Let's see how much of it I can cover in this session. ## Timestamps * [TBD] #nixos #home-manager #devops #linux #homelab

I’ll walk through how everything fits together, what I’ve learned so far, and how I plan to evolve it over time. In the last session, I dragged on longer than I expected to work with the new test VM I built. Basically I couldn't deploy any configuration to it. After that session I spend some time on the problem, and after learning several details about TTY/PTY and piping over SSH, it seems like everything is working. In this session, I'm going to share what I've learned so far, what the errors I faced were, how I fixed them, and some design decisions around it. ## Timestamps * [TBD] #nixos #home-manager #devops #linux #homelab

I’ll walk through how everything fits together, what I’ve learned so far, and how I plan to evolve it over time. With the new test virtual machine setup out of the way, it's now time to finalize my secret management strategy by keeping secrets in a separate git submodule. I will use it as a flake and give exclusive access to the Caddy service to use it as an environment variable. ## Timestamps * [TBD] #nixos #home-manager #devops #linux #homelab

I’ll walk through how everything fits together, what I’ve learned so far, and how I plan to evolve it over time. In this session, I'm going to first invest some time and implement what Andi suggested in the previous part and use `build vm` for testing my setup (instead of the VPS, which I was using). Then I'll continue solving the issue of requiring the secret files to be shared within the repository for age-nix to work. ## Timestamps * [TBD] #nixos #home-manager #devops #linux #homelab

Building a DNS Server from Scratch in Zig! After completing Ziglings, I'm taking on the #codecrafters DNS challenge to push deeper into systems programming. Live and unfiltered. Well, after grinding some time in the past few days on this project and rewriting a bunch of it, it's finally done. In this short live session, I'm going to give a quick tour of changes and what I've learned so far. I'm sure it'll be fun, so CHALLENGE ACCEPTED 💪🏼🤓. ## Related Playlists: - https://www.youtube.com/playlist?list=PLvWC0OdoEeTgVkVMyvBSgvwv4_oVI0bkF - https://www.youtube.com/playlist?list=PLvWC0OdoEeTh7ZQuJXq42YVuNRC4PcBsY ## Notes: - ✅ Session 1: https://sourcery.zone/articles/2025/09/livestream-log-building-a-dns-server-in-zig-part-1/ - ✅ Session 2: https://sourcery.zone/articles/2025/09/livestream-log-building-a-dns-server-in-zig-part-2/ - ✅ Session 3: https://sourcery.zone/articles/2025/09/livestream-log-building-a-dns-server-in-zig-part-3/ - ✅ Session 4: https://sourcery.zone/articles/2025/09/livestream-log-building-a-dns-server-in-zig-part-4/ - ✅ Session 5: https://sourcery.zone/articles/2025/09/livestream-log-building-a-dns-server-in-zig-part-5/ - ✅ Session 6, 7, and 8: https://sourcery.zone/articles/2025/09/livestream-log-building-a-dns-server-in-zig-part-6-7-and-8/ - ✅ Session 9, and 10: https://sourcery.zone/articles/2025/09/livestream-log-building-a-dns-server-in-zig-part-9-and-10/ - ✅ Session 11: TBD - ✅ Session 12: TBD - ✅ Session 13: TBD - ✅ Session 14: TBD - ✅ Session 15: TBD - ✅ Session 16: TBD ## Timestamps - [TBD] #zig #lowlevelprogramming #systemprogramming #coding #codinglive

Building a DNS Server from Scratch in Zig! After completing Ziglings, I'm taking on the #codecrafters DNS challenge to push deeper into systems programming. Live and unfiltered. So, finally, in the last session, I managed to solve the compressed question section parsing, caused by the drift on the offsets (I was using header length, while the function wasn't getting the header portion). In today's session, I'm going to continue my progress and resolve the issue of using label format in the response. I'm sure it'll be fun, so CHALLENGE ACCEPTED 💪🏼🤓. ## Related Playlists: - https://www.youtube.com/playlist?list=PLvWC0OdoEeTgVkVMyvBSgvwv4_oVI0bkF - https://www.youtube.com/playlist?list=PLvWC0OdoEeTh7ZQuJXq42YVuNRC4PcBsY ## Notes: - ✅ Session 1: https://sourcery.zone/articles/2025/09/livestream-log-building-a-dns-server-in-zig-part-1/ - ✅ Session 2: https://sourcery.zone/articles/2025/09/livestream-log-building-a-dns-server-in-zig-part-2/ - ✅ Session 3: https://sourcery.zone/articles/2025/09/livestream-log-building-a-dns-server-in-zig-part-3/ - ✅ Session 4: https://sourcery.zone/articles/2025/09/livestream-log-building-a-dns-server-in-zig-part-4/ - ✅ Session 5: https://sourcery.zone/articles/2025/09/livestream-log-building-a-dns-server-in-zig-part-5/ - ✅ Session 6, 7, and 8: https://sourcery.zone/articles/2025/09/livestream-log-building-a-dns-server-in-zig-part-6-7-and-8/ - ✅ Session 9, and 10: https://sourcery.zone/articles/2025/09/livestream-log-building-a-dns-server-in-zig-part-9-and-10/ - ✅ Session 11: TBD - ✅ Session 12: TBD - ✅ Session 13: TBD - ⭐ Session 14: TBD ## Timestamps - [TBD] #zig #lowlevelprogramming #systemprogramming #coding #codinglive
