Granted, I didn't study computer science in college. I had done some programming before and didn't really want anything to do with it professionally--I wanted to work for the Travel Channel! So when I fell into doing data journalism for CQ, a job that's halfway between storytelling and interactive coding, I knew there were skills where I was probably behind. And now that I feel like I'm relatively up to speed on the languages themselves, I want to catch back up on some of what I missed, starting with various low-level data structures.
These posts are also intended to leverage a truism: that the best way to learn is to teach someone else. By writing the blog as a teaching tool for other people, it forces me to organize my thoughts into a logical, coherent narrative: what are the foundations of this structure? What's it actually doing during this algorithm? Why is this useful? When the goal is to educate, I can't just get away with refactoring someone else's example. I need to know how and why it's built that way--and that knowledge is probably more useful than the example itself.
