> "Playing with your kids" is not mutually exclusive with doing open source work. Linus Torvalds (of Linux fame) is a father and so is Doug Cutting, founder of Hadoop.

I think the context here is doing Open Source work in one's spare time. And I guess that Linus does it mostly during the daytime. (I think his diving software thing has probably been done in the spare time, though.)
