I have to recommend the amazing MIT Structure and Interpretation of Computer Programs (SICP) lectures and book.
It gave me a whole new understanding of software and programming.
It continually inspires me.
The ideas have helped me to understand new technologies, languages and frameworks and put them into a larger context.
Just try not to be scared off by the lisp ;)
The book is available for free :
