Planning Extreme Programming
However skeptical the ads make you, it's hard to deny that what used to be considered supercomputing power keeps showing up in consumer-priced boxes, and the threshold of what really is extreme has crept steadily upward. If you're planning a project of more than average size, though, the review that chromatic contributed below of Planning Extreme Programming could be a valuable read, and the ideas in the book itself could save you a lot of money and time. Even if you have no plans to desire to install a beowulf in your broomcloset, it's interesting to consider what sort of thought must go into any large-scale programming project.
