Playing with my VPS again

I've decided to keep my cheap VPS from SSDNodes (disclaimer: it's my referral link in case you sign up!) and want to experiment with Ubuntu server again to get comfy with my linux commands. I miss the days where I worked on *nix stuff everyday. I want a job where I can do things like this all the time. Sysadmin/engineer/devops/dev? Not sure. But time to get applying :)
