I might argue with "An extension of this to make things even easier for future re-use is container technology." Containers are good for a bunch of things, but by hiding a lot of the details of source code and its dependencies, I think they make it harder for the future you to work with code. On the other hand, they are a good way of packaging a code and its environment for use (as opposed to modification or understanding) by others.
