Today’s idiom of the day is a debugging one. Find the first error message. Read it. There are many idioms that come out of debugging, and todays should seem obvious to you, but experience shows that it’s a little subtle. When a system fails there’s a good chance that there’ll be more that one error in the logs, and the later failures may be caused by the early ones. Making sure you identify and work on the first error will save you a great deal of effort.
