Started with Mac, switched to Windows and finally ended up with Ubuntu, just before Unity was introduced (must have been somewhere in 2011).
Currently mostly active in Python, but (starting to be) interested in other languages as well. Although I love the actual coding, thinking in concepts and "chewing" on seemingly impossible situations is what interests me most.
