3.0 von 5 Sternen Excellent concept but rather disappointing mistake density, 22. Dezember 1999
I rate this book 5 stars for the idea and -2 stars for all the confounding little mistakes. Apologize, I don't have too many details because it was one of the few books I borrowed that I actually returned (and to the original owner).
I went through two of the patterns with full concentration, found mistakes in both and found they really did get in the way. Things were named or referenced in ways that just couldn't be right. I wrote to the authors about a few issues (e.g. on pg 275, Widget should reference DialogDirector, not aggregate it) and the response (Johnson, Vlissedes) was very kind and constructive. But I believe there is significant work remaining. You may think I'm being overly picky here (at issue on pg 275 is an itsy bitsy little shape), but try understanding something completely new when there is one mistake in it. You wonder if you're comprehending wrong.
I have a hunch that most folks here, pardon my presumption, who are rating high without reservation are really in love with the idea of finding patterns to design (as am I). But I wonder if they've ever really really tried to go through any of the examples at a finer resolution than a bird's eye view. The book does a lot to crystalize the dream of reusable design patterns but not as much as it could to wake us up to realizing it.
Still it's on my list of things to buy because it's darn thought-provoking. Maybe that's it's highest purpose: to announce, if only by the title, the shocking idea that there could be patterns to design, that programmers might not always have to reinvent the universe with each project. (The idea that they don't is not new, but the *fact* that they don't is making woefully slow progress.)
The big question I still have is did they pick really good patterns and objectify them with compassion and vision? Are these the very paradigms and clumps of computational power that will be in the toolbox of programmers yet unborn? Dunno. I suspect from the tactical gaffs that strategic corrections are in order.
Maybe 3 stars isn't harsh enough but it's certainly a pioneering book. I believe one significantly better will come out in the next decade. It would be nice (somehow in my rosy view of the world) if it were by some of the same guys...
