Traditional approach is usually following waterfall model where requirements are captured upfront. Most of the time these requirements are not complete or adequate enough, which later results in extra [...]

There may be a problem scenario with Factory Method, as having a sub-class for each product may not be desirable. This may be over come by [...]

I have come across the Singleton Pattern. The way to use a SingletonDestroyer (SD) class to “KILL a Singleton instance” is interesting. In John’s approach, destructor is made protected so that the user is not allowed to delete the singleton instance explicitly, also as said Singleton [...]

It is an addiction to Singleton pattern. :) Singleton pattern allows only a single instance of a class with a global access. Now my addiction is not on its over use in code, but because of lot of preaching to my team mates about singletons… It [...]
