This book gives, as its title mentions, a brief history of computing across the ages, concentrating mostly on the late 19th century onwards, with mentions about important events and persons in older eras.
Even though there is a good amount of content in the book, and one indeed gets a grasp of how nowadays computing came to be, I did not find the reading enjoyable. The writing style feels more like an enumeration of items rather than a cohesive narrative with a central conductive thread. Maybe the intention was never to have that kind of writing, but my impression was that they tried, but failed. For example, at the beginning of each chapter there is an introduction that mentions a summary of what each subsection is about with, in my opinion, little emphasis on how the subsections are connected, giving little value (to the point that I started skipping introductions). Then subsections follow giving more details about the particular subject. Finally there is a closing conclusions section, which basically repeats the same that the introduction said (to the point that I started skipping them too). The subsections themselves also felt disconnected, and it wasn't odd to find typos, duplicated words of phrases, or sentences that abruptly didn't finish at all. References to the figures in the book were consistently slightly out of place too.
