A collection of 11 essays by ThoughtWorks employees, this is the 2nd such collection from the company. Unlike the 1st collection, this time they are grouped -a bit uneasily- into 4 categories, but the only value the grouping provides is to signal to a prospective reader in which topics the book is a bit heavier than in other ones. Languages and Testing in particular are treated in depth.
Like in the first collection, the breadth, the width, and the style of the essays varies a good deal, and probably every reader will find some of them interesting, some pointless, and some in between. That calls into question the value of them being published together. Anyone practicing in the software development field who's a bit interested in following trends will not find much new material here, although any given essay may hit just the sweet spot for a particular reader. For someone who hasn't followed the field closely and wants to reacquaint himself, or just broaden his perspective, the book may well provide some fresh ideas, sort of like going to a conference provides fresh insight on some topics where one didn't even know that fresh insight was to be had.
Disclosure: I received a copy of this book from the publisher in exchange for writing this review on behalf of CodeRanch.
