My parents have been my loving support all my life, and I could not teach my programming students were it not for the way my dad taught me as a wee tot at the dinner table all sorts of groovy things about science by drawing on his napkin, and of course the Taiwanese Apple ][ clone we got back in the early 1980's.

I would also like especially to thank my students for attentively listening. Not everyone does this any more. If they were not listeners to at least some tiny degree, I would not be able to help them. But they listen and learn to listen more by seeing the good, concrete results that reward good listening.
