Refactoring

Refactoring

Definition: I will go with the dictionary definition

Refactoring (noun): A change made to the internal structure of software to make it easier to understand and cheaper to modify without changing its observable behavior.

Refactor:

So, what is refactoring?

Does it mean just cleaning of code, the answer is just, but I feel it’s more than just cleaning code. Refactoring provides a technique for cleaning code in a more controlled manner and efficiently.

Developer productivity will increase the more they learn about refactoring methods, the more they use them the more they can reduce bugs in their code.

Purpose of refactoring:

1. Make the code easier to understand and modify
2. Refactoring make little or no changes to the overall functionality of the component (observable behavior)
3. Like Performance tuning – helps in improving the speed of the application, without altering the actual functionality, similarly refactoring help in cleaning small amount of internal code without changing the actual functionality. 

In next post i will start with other refactoring methods

Categories of Patterns - Design Pattern

Types of Design Patterns

As mentioned in earlier post, there are 3 categories of deign patterns.

1. Creational Patterns
2. Structural patterns
3. Behavioral Patterns

Creational patterns

The names creational itself conveys, that the design patterns under this category, all revolve around object creation in terms of who, what, how and when. Creational patterns all the systems separate the process of object creation, composition and representation. Creational pattern hide the detail of how the object / instance of classes are created.

Patterns falling under this category are:

• Singleton pattern
• Factory pattern
• Abstract factory pattern
• Prototype and 
• Builder pattern

Structural patterns

Structural patterns revolve around the class and object composition, what I mean is it helps us to understand how different classes in a system are glued together in a extensible and flexible manner. The object composition shows ways to compose objects to obtain new functionality.

Patterns falling under this category are

• Adapter pattern
• Bridge
• Composite
• Façade
• Proxy
• Flyweight
• Decorator

Behavioral pattern

Describe the way object and classes behave / interact and divide the responsibility among them. Thee pattern are more concerned with the communication between objects and classes.

Pattern falling under this category are:

• Command
• Interpreter
• Iterator
• Mediator
• Observer
• State

In the next post I will tart explaining in detail patterns falling under Creational pattern

Chromecast

Hi,

Yesterday i got a chrome-cast for $35 for tax, and here are some of my review comments.

Pros and cons

Pros

• Easy to setup the devices
• Quick install of the software
• Easy /two click cast
• Sharing Desktop (Crashes sometimes)
• Streams you tube and chrome apps from dongle rather from the laptop / tablet

Cons

• Needs Chrome to be installed for casting internet stuff
• Does not allow screen extending. ( i know its a streaming dongle)
• Only Google apps ( are cast in full screen) - eg - you tube
• app that are not tied to Google are not cast full screen, so user cannot do any thing if the laptop screen is made full.

More details on this..

Displaying Curly Braces { } in Console ouptut

Recently I was working on a sample console application for my tutorial and I happen to have a requirement, where in I had to display the curly braces as part of the formatted output.

Here’s the example ; Output of the console program should be: The number is -{124}

Solution:

As you are completely aware that curly braces is part of the c# keywords, for formatting object (e.g. numeric or string or class object etc.)
{
string x = “124″;
Console.WriteLine(“The number is -{x}”, x);
}

output : The number is -124

in the above example the output is still missing the curly braces, the solution to this is adding twice open and close {{ }} curly braces to get the desired output. Note is only for curely braces for all other special characters you need to use ‘\’
{
string x = “124″;
Console.WriteLine(“The number is -{{x}}”, x);
}

output : The number is -{124}

Thanks,

Design patterns – Introduction

Design Patterns

Every one who is in the software industry has heard it about design pattern,have worked on it (knowingly an unknowingly) . Software engineers with 1-2 years of experience gets impressed with people, who is talking on design patterns and explaining one or two patterns. Everyone is interested in learning and knowing design patterns, a single search in Google would give 1000 of search pages, explaining design but for some reason it never been explained in a simple or lucid way. At least the type of material available make it more complex and second most important is the time invested in understanding them and trying to implement them.

In this and future post I will explain what design patterns are in an easy and simple language (avoiding the jargon). 

Take an example.. while making a recipe /cooking, we do one of the two things, 1. start cooking (if we know cooking ) or 2. search on the web for recipes before we start to cook, so that we can get help and make make a dish.. We try following exactly the same steps, use the same same ingredients and quantity, so that recipe comes out good, a lot of them succeed in getting the recipe to the mark and this continues.. people follow it..

Design pattern are some what, recipes – they were tried and tested solutions and now they have been documented for other to use. Design pattern are not a complete solution to software problem, but guide you to in getting started to solve the problem..

The 3 mains areas where in design pattern are in creating objects.., defining structure of software solution/ Architectural and defining communication between objects. This clearly indicates design patterns revolve around object creation, architectural structure and object communication..

They are broadly classified..

1. Creational

2. Structural

3. Behavioral.

Debugging a Javascript in ASP.NET

There are two ways you can debug a javascript code in ASP.NET (visual Studio IDE)

I. Usingthe Internet Explorer Process  in the Attach to Process window

II. Using the debugger keyword.

Method I

• In the Visual studio IDE open javascript .js file  and a breakpoint at the line you want to start debugging the code.  Now click on the menu (Debug | Attach to Process) on the top to open the Attach to Process dialog window (see below) select the  Internet Explorer process (iexplore.exe) from the list of available process a. Execute the code you want to debug in Internet Explorer.

Method II

• In the Visual studio IDE open javascript .js file  and type the keyword debugger where you want the code to break in to debugging. this
•  . Write your JavaScript and place the debugger keyword where ever you want the code to break into debugging. The JavaScript interpreter hits this  keyword and halts execution and returns the control back to the IDE. This is like setting a breakpoint inside of Visual Studio.

Note: you must enable script debugging in Internet Explorer to be able to debug. Go to Internet Options inside Internet Explorer and then go to the Advanced tab. Uncheck Disable script debugging (Internet Explorer).

How to completely remove TFS (source control) bindings from a visual studio 2008 solution

There are two ways to remove source control bindings for a solution:
1. Open the solution in VS, then click on File Menu – - >> Source Control –>> Change Source Control and then unbind and/or disconnect all projects and the solution. This changes will remove all bindings from the solution and project files on the local folder.
This solution when distributed or provide will not poup for TFS connection or TFS ofline when opened in VS IDE.
Once this is done you can again you can switch the Souce Contro provider in Tools -> Options -> Source Control -> Plug-in Selection) to get TFS

2. The simplet way to unbind a solution from TFS is to, open the solution you want to clean in VS IDE and remove the TFS Plugins from IDE using Tools menu –>> Options –>> Source control –>> Plug-in Selection. Select None from the dropdown and click ok. Visual Studio will ask to remove source controls bindings
Close the solution and reopen the solution. THe solution is now completely unbinded from TFS..
