Here is another software update of everyone's favourite no-blog. With this release admins can change the text on the "About" page and the text on the master page. However what really matters is that with this release the Personal Webpage Engine passed the official "Works on My Machine" certification program. I have proudly added the official certificate badge to the website.

Just to remind to any of you who might want to view the code or submit a bug (not that I care about your bugs, mortals), here is the project page on Codeplex - http://www.codeplex.com/BlogNET.

# Futurama: Bender's Game

Good news, everyone! Новият Futurama филм вече може да бъде откраднат от любимия ти източник за крадене на филми. Този път тематиката прелива от енергийна криза към фентъзи. Лийла има проблеми с контролирането на гнева, а Bender с контрлирането на въображението си. Обилно ни заливат препратки към Властелина на пръстените, а сестрата в лудницата за роботи се казва Ratched.

# C# 4.0 Features Announced

The big news (actually the big news was Windows Azure but I care more about C# 4.0) from yesterday is that Anders (Hallowed be his name) has spoken. The future of C# have been announced. I bet that many of you mortals are eagerly awaiting my interpretation of the words of the Prophet.

# OOP in Math

My coworker Lyubo came up with the following OOP problem while we were having lunch the other day. He says it is a well known problem that you can see on numerous places but it is new to me.

We know from mathematics that the square is a special case of rectangle. In OOP terms "special case" means inheritance. Obviously the mathematical square inherits from mathematical rectangle. Your task is to create OOP model for that relationship. Lets say that we want the rectangle to expose get property (getter for you Java readers) – the area of the rectangle. This is not as simple as it sounds. Here is one of the simplest (and very wrong) solutions:

class Rectangle
{
/// <summary>
/// A side of the rectangle
/// </summary>
public uint A { get; set; }

/// <summary>
/// B side of the rectangle
/// </summary>
public uint B { get; set; }

virtual public uint Area
{
get { return A * B; }
}
}

class Square : Rectangle
{
public override uint Area
{
get
{
return A * A;
}
}
}

However this means that the B property is not actually used. This can lead to unexpected results in polymorphic client code. We expect a rectangle to have a area of A*B and somehow it will not if it is an instance of Square. We can override the property setters, add some exceptions but what inheritance means is that the child class can do ANYTHING that the base class can. If you need to add special case behavior for any of the child classes then the inheritance hierarchy you have created is simply wrong. So go ahead make it right... (or view full text for explanation)
