This is so funny I had to share it.

Somewhere in some troubleshooting forum (it does not matter where) a certain technical issue is being discussed (it does not matter what) and user ’tattoodavie’ leaves the following comment:

i have the same problem but i have windows 7 ultimate 7600 installed on an asus X83Vb-X2 notebook, but i also have another problem… i cant get into the bios and set the clock, change the settings… nothing…its password protected. it was my ex-girlfriends, she bought the laptop, but gave it to me for me for my birthday, turns out it came from a pawn shop, which one i will never know, seeing as how we cant talk to eachother any more (court order) i have no clue how i can clear the password. I have had it for some time now, and have grown too attached to it to. i just installed windows 7 and the new NVIDIA 182 driver for its GeForce 9300m GS 512mb graphix card. and now every time i restart this thing it sets the time and date back to 12/05/2008. I assume thats the date it was built. any ideas what the he** is going on?

![[media/spring-in-action-cover.png]]My notes on the “Spring in Action” book by Craig Walls and Ryan Breidenbach from Manning Publications Co.

These are my notes on the book “Clean Code” by Robert C. Martin from Prentice Hall.

I am in agreement with almost everything that this book says; the following notes are either quotes from the book which I found especially interesting and/or especially well written, or they point out issues that I disagree with, or errata which objectively need correction. If some point from the book is not mentioned below, then I agree with it.

As it turns out, an explicit interface method implementation in C# must be tied to the base-most interface to which it belongs; it cannot be tied to a descendant interface.

        interface A

            void F();
        }

        interface B: A
        {
        }

        class C: B
        {
            void A.F() //OK
            {
            }

            void B.F() //error CS0539: 'B.F' in explicit interface declaration is not a member of interface
            {
            }
        }
    }
}

Well, sorry, but… it is.

This is a blooper of the Common Language Runtime (CLR), not of the language itself: Stack<T> and Queue<T> derive from ICollection, but not from ICollection<T>, so they do not support the Remove( T ) method! Why, oh why?

When writing generic methods in C#, it is possible to use the ‘where’ keyword to specify constraints to the types that the generic parameters can take. Unfortunately, these constraints cannot be used for resolving overloaded methods. Case in point:

        public static bool Equals<T>( T a, T b ) where T: struct //error CS0111: Type 'Test' already defines a member called 'Equals' with the same parameter types
