An effective way to glean unusual information, collect anecdata and get a general feeling of how things work with a particular topic, is to read the top discussions of a few forums, such as Reddit or Hacker News. Reddit is a huge platform with many topics, so you must identify the relevant subreddits. Stack Overflow is more structured but you can still find nuggets of arcane knowledge.

I do not rely on books that much, but I remember the Cormen foundly for how he got me up to speed for the most common algorithms and data structures.
- Introduction to Algorithms by Cormen et al.
- A trip through the Graphics Pipeline
- Simple Top-Down Parsing in Python (simple parsers)
- What every programmer should know about memory
- What Every Computer Scientist Should Know About Floating-Point Arithmetic
- Latency numbers every programmer should know (see also https://gist.github.com/jboner/2841832)
- The Evolution of Trust (game theory)
- How to Remember Anything Forever-ish (spaced memorization)
Practice makes perfect and programming challenges are more effective than personal projects at pushing you out of your comfort zone. Of course, personal projects are much better to learn how to build an actual project.
