You username is a bit of a clue to your IRL name

Good. I'm not paying for my stuff to be thrown around. Especially my fragile shit.

Where do you get the million dollar figure?

W10M is still in development. I also don't like how slow it is.

If you'd like, I can try and see if I can dig up my university programming course material (No assumed knowledge, and all in Python). Also, I'd be happy to work through questions your son has. (I'm a 4th year Engineering Student).

If your son is looking for some challenge, the Project Euler site is a great place to start, and is completely independent of the programming language you choose. Problem 1 is quite easy, problem 530 is extremely difficult. The good thing here is that it requires you to apply a principle--that is, your code won't work unless you solve the puzzle correctly and cleanly.

Khan Academy is another great resource, although the project is starting to get very big, the computer programming stuff is rock-solid.
