Offtopic, but does anybody know how the diagrams in this article were generated? I'd love a simple piece of software to generate beautiful, straightforward pictures like this to explain architectural problems.

I don't think that it generated these diagrams, but you should check out planttext (http://www.planttext.com/) - makes UML diagrams easy.

I don't know about the article, but DOT[0] + graphviz[1] could be used for this.

On Mac, I've always liked OmniGraffle for architecture diagrams.
