Dependancy Injection

How would you pass a static class like the Console?  I am not seeing good solutions out there

Favor composition over inheritance

I guess VB6's class model wasn't so bad after all.

Factory pattern with DB objects

make sure the server (IIS) is not caching the structure of your objects if you are getting errors upon changing the sp's

Immediate invocation in Javascript

is handled, for example,  thusly

(function ($) {
})(jQuery);

the () is needed because otherwise JS thinks function is a decleration, the JQuery is passed in

 so the code can now reference JQuery as a "$" without having to traverse the scope chain looking for the variable

Patterns and problems

I was reminded of patterns when I read E.O wilson's Letters to a Young Scientist that every form of life is an answer to a problem.

Here is a short list of patterns and problems they attempt to answer

Pattern	Problem
Singleton	Only one instance of an object
Strategy	Apply functionality only where needed - not the whole inheritance chain
	Avoid multiple switch statements
Observer	Loosely coupled way to notify
Template	force child classes to implement what they need (by making those methods abstract) , but follow the parents process
Factory Method	Method for subclasses to create correct class
	Works in tandem with strategy
Abstract Factory	Defer concrtete implementation for child classes
	Avoid multiple switch statements
	A way to have multiple versions of a class
Façade	Simplify gateway to single/multiple interfaces
Command	Loosely coupled way to execute a method
	good for Qeues

Example of Singleton pattern

    public class sing

    {

        private static sing Sing;

        private sing()

        {

        }

        public int x;

        public int y;

        public static sing SING

        {

            get

            {

                if (Sing == null)

                {

                    Sing = new sing();

                }

                return Sing;

            }

        }

    }

static void Main(string[] args)

        {

            sing.SING.x = 7;

            Console.WriteLine(sing.SING.x.ToString());
