I Rebuilt My Dotfiles for the Agent That Writes Them
I don't hand-write my dotfiles anymore. An agent does. So I rebuilt them for the agent, and almost four years of Ansible went out in one commit.
You can call me Dufus.
Hello from the command line
I break things, fix them, and write down what actually worked.

I Rebuilt My Homelab for an AI Operator
I didn't add AI to my homelab. I scorched it and rebuilt it from bare metal so an agent could run it, and picked every tool for the operator instead of for me.
From Hardware RAID to ZFS on My R720xd
I pulled the RAID card from my R720xd, put in an HBA330, and rebuilt Proxmox on three ZFS pools without buying a single new drive.
Deploying Obsidian Sync for My AI Agents
I set up Obsidian Sync for AI agents in a terminal-only Ubuntu Server environment using the official CLI and a continuous systemd service, then retired my old GUI workaround.
The AI Internet Outage We're Not Ready For
I think we are underestimating how close we are to a tipping-point outage where failure in core internet systems cascades far beyond one provider incident.
I Deleted My Cloudflare Tunnels: Tailscale Operator for Homelab K8s
I replaced Cloudflare Tunnels with the Tailscale Kubernetes Operator and went from dashboard-heavy setup to GitOps-native service exposure.
The lab.
One server, three Talos nodes, all of it in git. Mid-rebuild.

Hello, I'm TechDufus.
I'm Matthew, but most people online know me as TechDufus. I started in PowerShell, worked my way through DevOps, full-stack and platform engineering, and now I build with AI and teach others to.
If I repeat something twice, I script it on the third pass.
