More progress on code academy is going well.  I'm just learning about functions - how to declare them and call them - a very useful concept and also available in basically all other programming languages.  I've also been told about interrupts which I think are so cool.  Interrupts are basically a subroutine (function) that is automatically called based on some form of input or a clock (timer).
