Sometimes old technology becomes new again. The other day someone was showing me their Blackberry device that has a low overhead mail reader, very similar to PINE which I used until very recently when I switched to Outlook. I just had my groceries delivered last night, which is not really that new of an idea since my grandfather used to deliver milk to people's homes (though he did it by horse and buggy).

This entry acknowledges the code of our very own MathWorks developer, Ben Hinkle.
