    - by mikemay
    Someone on the Herding Code podcast No. 68, http://herdingcode.com/?p=231, stated that IOC containers had no place with Python or Javascript, or words to that effect.

  • Interface in a dynamic language?

    - by Bryan
    Interface (or an abstract class with all the methods abstract) is a powerful weapon in a static language. It allows different derived types to be used in a uniformed way.
