About

I am “Some Dude” - a systems administrator, engineer, devops, whatever the latest buzzword is. I started these pages as a place to write down some notes so I can refer to them later, if necessary. Hopefully, someone else might find something useful here as well. All information is provided as is. As with everything on the internet, you should exercise discretion before implementing anything from these pages in your own environment.

I am always on the lookout for new employment opportunities in the EU. Feel free to contact me.
