Ask HN: What good books have you read to learn more in tech?

I know we learn best by doing, but reading can help cover some concepts that I may miss as I build projects. I'm taking some intro to CS classes and am open to suggestions on what to read in my down time.

I'm focused on learning some foundational concepts of CS and data analysis. I work with a company that has a distributed computing platform. I'm sure you experts out there can point me in a good direction.
