A must listen, if you want not only to learn (or to recall, for some
of us), but also there is a lot of fun brought by Randal tm :)

Let the 'serious' programmers write their multimillionaire lines of
half-working code in C, and let people like Dan, write a systems like
Lively Kernel just for fun of it!
We need to understand, that Programming HAS TO BE FUN, it should not
be a slave labor. Because history shows us that slave labor is most
ineffective way in doing anything and that's one of the reasons why
great empires fall. People just like to have fun!
