It's a horrific article that starts off wrong by equating specification with code. In reality, the relevance of a specification comes with substantial abstraction that its author doesn't care about. The goodness of a spec is not just from what is defined, but also from what is left out. Code on the other hand leaves nothing out, unless you get into compiler level optimizations. The two are not the same.
