After a cursory glance, it seems a lot like Code by Petzold[1], or at least a similar concept in less detail. I loved that book, and I know most others did as well. I'd love to take a look at it.

I read both. D is for Digital takes up where Code leaves off. It's an easier read, Code gets harder near the end.

I just starting learning programming in January, and both Code and D is for digital were indispensable for the context they gave me.
