My first install of Linux was in my 20's. Needed to learn Linux for my degree. After that I was working at MS shops and never had a use for Linux. About 10 years ago I had to do some admin work on a SLES install and have been working with Linux systems since. Been completely MS free for nearly 6 years now. My wife's laptop was the last machine that had a Windows install.
I want to learn Rust, but I have no real use for it other than tinkering around at home. Might pick up Ruby again since we are using Chef more at work now.
