This lively book is not a manual or a how-to guide; it's a rallying cry for the community of "benevolent hackers" and an attitude adjustment for those who want to join. Bill Jensen, CEO of the Jensen Group, and Josh Klein, a skilled hacker, offer an enthusiastic spirit and an all-embracing outlook - at times to make up for being reserved about specificity, so as not to enable bad hackers - that clearly deliver their message: Courage and flexibility matter much more than technical expertise when it comes to changing oppressive work conditions. The authors walk a tightrope: They imply that you can alter software, networks and processes, but they never demonstrate how outright, and they advocate hacking only within ethical limits. Their obvious joy at circumventing restrictive or idiotic corporate practices, and their welcome conversational tone, makes this a tremendously fun read - one that will open some readers' eyes to possibilities they might not have considered. getAbstract suggests this gleeful tome to those who feel that work procedures are dampening their productivity and creativity, and to anyone who likes to tweak the nose of authority.
