I consider reading an essential part of my learning process. While I spend a majority of my time hacking away, I devote some (not enough) time to keeping up on certain blogs and newsletters. This reading is not just to improve my programming knowledge, but also to learn the lingo and understand workflows.
Here is a list of all my reading material by topic. Some of these are updated regularly, some aren’t. Some are focused solely on programming, others aren’t. Together they make for a good mix of educational topics and the lives of software developers.
Edit: I’ve added a great list of video resources too.
