I usually leave a URL for stack overflow answers or other advice as a comment in what I'm working on. I know some areas of my code are more sensitive than others. It is good to have an understanding of what you are doing of course. Sometimes a stackoverflow link is removed simply because the mode of thinking is wide spread in the application and I no longer need the note to it. Might be worth searching for my links in the code when it is time for release incase there is any funny business. Stackoverflow usually tells you if you "shouldn't do it in production".
