I use Macs to develop, but of course deployments happen on Linux so I have good knowledge of that, too. Windows not so much.

Other

When I don*t spend my time with my family (or anyone of us three is sick) I go out to take pictures with my http://urbanhafnerphoto.comanalog cameras (and develop the film at home). This is a nice change to spending the whole day in front of a screen.
