Joel on software -- new favorite book

Man, this is an awesome book about software engineering:

So, basically i have two things in my life that I like "doing":
1 - learning about Islam
2 - learning about software and writing software.

(why isn't practicing islam or spending time w/ family on there? because it's a given and doesn't really "fit" in an enumerated list... These things integrate into numbers 1 and 2).

So in the second category, "Joel On Software" is my favorite book, dang he's good.
