The name of this chapter is “Know Your Code.” You might think that if you wrote a piece of code, you know it well. You probably do. You know it at least as well as anyone else. Even if you’ve written the code, however, you will still make assumptions based from your memory. These assumptions will likely move further and further from reality as time goes on. You have a best guess—an educated assumption—but that is subjective and dependent on human frailty. And if you didn’t write the code, all bets are off.
