Coding keeps me healthy. My main StackExchange haunt is Stack Overflow. My pet project currently is the Little Go iOS app. My level of activity on SO varies, but the importance of #SOreadytohelp remains constant.
I avidly read Science Fiction, mostly older stuff, which is probably why I don't like scifi.stackexchange.com very much.
I get very excited by Space Exploration. Nobody around me shares my feelings, so I regularly make a fool of myself. It may also have been a mistake to tell people how much time I spend exploring the semi-fictitious galaxy of Elite: Dangerous.
