Programming Paradigms at Stanford

Ever wonder what happens when you assign a value to a variable? No, I mean like where is it in memory. What does the binary string look like? What is the difference between an int and a short that are assigned the same value? Well, I guess I'm the only one that does but if you do to check out the Programming Paradigms class lecture video's from Stanford. They're really good and cover all the details. It's a little fast paced for me so I usually play the videos over two or three times but they have lots of great information in them. Not anything language specific but they cover stuff relevant to Assembly, C/C++, Python, etc.
