The Impossible, We Do Right Away....

Yesterday I was reminded of this post.  Some people do not understand how things work.  Even my upper management.

They want a change of the program's behavior, but they don't want the cost of that change - they don't want to run their tests, or restart their timetables.  They want you to somehow make the error go away without making them do anything different, and when you tell them that it's impossible, somehow you are evil from not trying.

If you face this often, you'll need to start programming defensively - making your programs as data-driven as possible, so that you can change behavior without changing code.  Now, this obviously fails to help when the problems are code issues (threading, loop limits, etc) - so you'll still need to be ready to deal with the nonsense.
