In summary, the idea is to try to give all of the information to help others to judge the value of your contribution; not just the information that leads to judgment in one particular direction or another.
I found the examples weren't directly relevant as I wasn't familiar with the languages, but the advice inside was invaluable.
I've gotten well past the halfway point of this book (2 chapters left). I skipped the first three chapters because they were on topics that were very basic (using svn, installing eclipse, and glossary of agile terms). The section on buildbots was quite nice, but I found the majority of the other sections to be so rife with errors in code and otherwise that it was hard to get past. The section on TDD was especially hard to decipher as we were testing a program when we didn't know what the implementation of the code was going to look like.
I would find this book hard to recommend to someone unless they weren't familiar with what agile development is. Even then, only for those who can gloss over several errors (ie: those who don't have OCD tendencies).
This is a graphic novel that's represented as a "slice of life" for some kid in Hawaii. Geared towards 13+ audience as there is drug use.
