I'm a bottom-up learner. To take bottom-up "fundamentals of CS" to an extreme (without venturing too far into electrical engineering): First, work your way through Kernighan & Ritchie and do EVERY exercise. Then read Hennessy & Patterson (Computer Architecture). When you're done, you'll understand exactly how a computer executes instructions, and you'll have an abstract mental map from C code to machine code.
