In this book I've collected more than 100 stories from software engineering, each story shows a mistake made by the best software engineers in the world, John Carmach, Martin Fowler, Rob Martin, Linus Torvalds, and many others, I've collected the stories they have told across their interactions in the internet, interviews, books, and put them in a single place, the result is an unvaluable list of mistakes to consider on your daily job as a software engineering, that will definitely increase your value as a professional, by giving you situations that you will face, but now with knowledge of what the bests in the industry have done and what they've found to be the wrong paths.
I was doing some research for a project of mine, I stumbled upon some Linus Torvalds posts, with discussions back and forward among other people, while reading those discussions, I read about 5 things that are usually mistakes when doing software, one of them was "don't copy code you don't understand"(you may have saw that discussion as well probably, it's somehow well known), in that moment I thought: "so many incredible engineers have stories, blog posts and books, online with their experience, so just collecting a lot of stories about the things they did wrong must be golden information", so I did just that, I spent several months collecting stories, creating chapters for the book, until it was finished, and the result is remarkable, so many things to learn from!
