I work in the Traffic & Safety department specifically designing the layout for the new traffic signals. I think it is crazy how Linux keep being mentioned on this thread but that is the OS I prefer in my home devices (Desktop & Laptops). Unfortunately the work place is too tie to other big corporation consumers oriented OS and that is what I have to work with.
Other than that I enjoy cooking and growing my own food and take care of some ornamental plants that grow in my back yard.
