I have been using NetLogo for agent-based modelling, and still use it for fun and personal interests. I occasionally do something with R for work.

Mainly here to:

• solve other people's problems with NetLogo (I know firsthand the struggle to face programming when you are not a programmer, which is many NetLogo users' situation);
• sometimes find R answers or ask R questions.

Personal and professional interests lie in the socioeconomic side of sustainability. Physics is that thing that I may have pursued, had I understood earlier that it would be a passion.
