As with all human endeavors, the tech industry has seen its fair share of blunders. From minor errors in grammar and punctuation that lead to temporary interruptions in service to massive catastrophes that result in fatal consequences, the author, a veteran “IT guy,” has seen them all. He provides a meticulous postmortem analysis in this volume, scrutinizing the data, hardware, and systems designs that few consider on a daily basis. Korga summarizes the famous, infamous, and forgotten events that have led to data breaches, the losses of billions of dollars, and (in the most extreme cases) deaths. Each section of the book contains a careful explanation of technical terminology and lists of lessons readers can learn from these famously spectacular gaffes. It all boils down to a single axiom: “Systems do not fail because they are poorly built. They fail because they are built by people.” Korga’s accessible analogies and approachable prose open a gateway to understanding for those readers not in the tech industry. His commitment to fostering a growth mindset among engineers and computer scientists makes for a refreshing take on the topic—this book is not about defaming the mistakes of hapless blunderers; it’s about an industry growing, learning, and ensuring that similar catastrophes don’t happen again. Korga encourages mindfulness (while acknowledging the boneheadedness of each mistake) in a witty, engaging manner, but he is sensitive to issues of tone; addressing the serious consequences of some of the events he covers, he writes, “I spent a long time wondering whether stories tied to real trauma should appear in a work that doesn’t shy away from irony, sarcasm, and the occasional silly comparison. In the end, I decided they must—because the lessons they carry are far too valuable to leave out.” The author’s conversational style makes this a relatable read for anyone who’s ever tried to do something and fallen down trying.
