// expertise
// background
2003 — First contact: Knoppix live CD. Love at first boot sequence.
When I first watched a Linux boot stream past me — services lighting up one by one — I knew I'd found what I was looking for. Four years later, Windows was gone for good.
// distro history
Running Arch as my primary OS for over 16 years. For server deployments, Ubuntu, Debian, CentOS, and Arch are my preferred choices depending on the workload.
