The document discusses the 'Ten Commandments of Egoless Programming,' originally proposed by Jerry Weinberg, emphasizing the importance of learning from mistakes, collaboration, and constructive criticism in software development. It highlights the necessity of treating colleagues with respect, embracing change, and focusing on the code rather than the coder during reviews. Additionally, it promotes a culture of teamwork and continuous improvement within coding environments.

You are not your code2
A code review will aim to reveal potential problems pretty
early, so that it won’t go to production.
Those issues are about the code, not about you!
Don’t take it personally!

respect
