Why programming is hard.
Anatomy of a Feature. I like this. I admit, I'm not done reading it, but its exactly the sort of thinking that makes me "slow" even when I have a productive day. (Another reason I'm slow is that I'm pretty ruthless when it comes to automation, I think this is also just an "interesting read" along those veins: Porting Syck - A story of C, parser generators and general ugliness).
