Aside from reading many lines of code, errors, and pages of documentation, when I find some time or feel like delving into a topic in depth, I often turn to books for their excellent in-depth explanations and often fun.
If it is not something related to my work, or a mystery or sci-fi story book or novel, I opt for the audiobook version and enjoy it either while traveling or at bedtime.
