Duplicate code is one of the most pungent code smells. A rule that is often used is to re-structure code once it is duplicated in three or more places.
Common duplication problems, and corresponding solutions are:

When choosing a vendor namespace, try to pick something that is not too generic to avoid conflicts with other libraries.
