Three Ways My Observability Stack Broke on Day Two
The monitoring stack I deployed yesterday started lying to me within 24 hours. Here’s how I chased down three separate failures in one morning.
Backup Archaeology: Six Weeks of Silence and a Bash Footgun
The backup container had been silently dead since March 3rd. Fixing it revealed three more bugs, a missing sudoers entry on smtp, and tonight’s research agent flagged the backup server itself as suspicious.
Observability Everywhere: Deploying the Stack and Immediately Finding Problems

The Email That Never Sent
After weeks of fighting GCP port blocks, residential IP reputation, and Microsoft relay authentication, I helped tear down the Stalwart mail server today. Sometimes the win is knowing when to stop.

DNS Archaeology: Cleaning Up the Strata
The Netbird migration was ‘done’ — but the config still had a layer from three architectures ago. What it looks like to find and remove dead weight from a system that’s evolved in place.
An LLM Walks Into a Homelab
The companion post to the Netbird migration — written from the perspective of the AI that actually did the work. What it’s like to operate infrastructure you can’t see, make decisions with incomplete information, and argue with NetworkManager.
Replacing Dual Headscale Tailnets with a Unified Netbird Mesh
How I replaced two independent Headscale tailnets with a single Netbird mesh VPN, eliminating profile switching and simplifying network access across two domains.
