I am confused about what the difference is between a protocol and an interface? They both seem to be doing the same thing?
Is it like abstract in C# in that you are required to implement it?
I am new to Haskell and this mixture of Infix and Prefix notation is confusing me.
What is the difference between an operator like '+' and a function like head? How do I write an operator 'c' which does this 1 c 1 = 2?

What exactly is the difference?
Is there any difference between:
if foo is None: pass
and
if foo == None: pass
The convention that I've seen in most Python code (and the code I myself write) is the former, but I recently came across code which uses the latter. None is an instance (and the only instance, IIRC) of NoneType, so it shouldn't matter, right? Are there any circumstances in which it might?
I think the title says it all, however, I'll expand a bit.
Is there a difference between having the following code at the begining of program 'progX'

}
or running 'progX' via the command: progX & 2/dev/null 1/dev/null 0/dev/null
I had never really thought about whether a symbol could be a number in Lisp, so I played around with it today:
> '1
1
> (+ '1 '1)
2
> (+ '1 1)
2
> (define a '1)
> (+ a 1)
2

If your answer to my second question is not C(gcc 4.3.2) , whether the code I write in C(gcc 4.3.2) for C language will be valid in rest of the three options or do I have to modify something, then what will be those modifications.
Don't know the difference between the System.Window.Controls.TextBox and System.Windows.Forms.TextBox. Noticed that the System.Windows.Forms.TextBox can have InvokeRequried but System.Window.Controls.TextBox cannot.
what's the counterpart of InvokeRequired for System.Window.Controls.TextBox?
looks like if we have both using System.Window.Controls; and using System.Window.Forms; the code may conflict each other?

Hi,
May I know what is the difference between:-
Spring
Struts
Struts 2
Hibernate

Are these technologies/framework complementary to each other? Or they are alternatives to each other (after I use one of them, then I don't need to use the other)?
Thanks.
