I studied EE, not Comp. Sci, but I drifted into pure software. Now software is all I do, but I feel like I'm "missing" things from my knowledge.

Can anyone recommend me any good resources (books, online articles) that would help fill these 'algorithmist' gaps? I know of things like complexity theory, how functions scale with time using O(n) functions or whatever, but I don't know much about them. I mean like kind of an overview of computer science topics; something which is wide but not deep.

I imagine there are other EE refugees like me who feel lost when they read Google interview questions :)
