These are personal notes and write-ups from my homelab and sysadmin work.
They are not “perfect tutorials” – instead, they reflect real lessons learned, fixes, and gotchas I encountered.
- 🔑 SSH Hardening – why key-based auth saved me more than once
- 🐳 Docker Best Practices – small tweaks that prevent downtime
- 📡 Unifi VLAN Setup – isolating IoT devices from LAN the practical way
- ⚡ GPU Passthrough Troubles – lessons learned when virtualization bit me
- ☁️ Cloudflare Tunnel vs Port Forward – why proxy is safer, real experience
- To document my own mistakes and fixes
- To have a knowledge base I can return to
- To show others (and myself) that sysadmin work is a constant process of learning
