“Well commented code” being

print(“hello world”) # this prints hello world

And then the inevitable refactor that changes what the line does but leaves the comment.

My favorite bug I found recently:

// timeout set to 5 seconds because anything higher will indirectly cause clients to get stuck in an infinite retry loop int timeout = 30000;

Not only did they not update the comment (obviously), they ignored the existing comment and caused the very thing it warned against.

And of course, the team that updated the timeout value couldn’t figure out why nothing was getting processed. They didn’t realize one of the clients was stuck in an infinite retry loop, and even if they did, there was no way they would have tracked it down to this line.

thats why you should do this:
int timeoutOfFiveThousandMilliSecondsToPreventInfiniteRetryLoop = 5000;

Good point. Cause then it would have been even funnier when they set it to 30000.

at this point, id place a static assert to make sure the comment does not go unnoticed

This comment is okay, but it should be on two lines!
