It's a description of Short, Self Contained, Correct (Compilable), Example. This would be a useful reference for many as a guideline for how to make code usable in questions on StackOverflow.
It's based on these 4 points
* Short (Small) - Minimize bandwidth for your example, do not bore the audience. * Self Contained - Ensure everything is included, ready to go. * Correct - Copy, paste, (compile,) see is the aim. * Example - Displays the problem you are trying to solve.
I thought it was pretty cool and could perhaps be worked into the SO FAQ or wherever.
Is this a useful guideline, and what other code guidelines might be useful for SO examples?
