Design Pattern --Factory Patterns

A Factory Patterns creates an Interface for creating object and lets subclass do the instantiation. A Factory Pattern lets a class to defer instantiation to the subclasses. Simply saying it abstracts the instance creation.
It lets the developer create an interface and retains which class needs to be instantiated. The Factory pattern comes under the category of Creational Patterns.
Generally when we create a class, we will provide constructors to the users of the class so they can create instances for the classes. But on some situations we need or should not give them the ability to create instances with the available classes. On such situations we can create Factory Pattern. That is rather than calling the constructors for creating objects, you are calling the Factory to create objects.

Its primary purpose is to create objects like a real work Factory.
Logical Model:
The prime actors of the Factory Pattern are:
· Client

· Factory

· Product

A product can be anything you produce in the factory. In programmatic angle it will the actual object which needs to be created.
A Factory is the one who creates object of the product.
A client instead of directly creating objects of the product uses the Factory to create objects for it. The client is not aware about how the objects are created.
Factory Pattern in .net Framework:
Some of the areas where Factory Pattern is used are given below,
 IClassFactory is an interface used to create instances of COM classes.
· System.Web.IHttpHandlerFactory class
· System.Convert
Example in C#:
In this example we are going to create we use Abstract classes instead of Interfaces as Abstract classes has the benefits like versioning, etc., over Interfaces.

using System;
using System.Collections.Generic;
using System.Text;
namespace FactoryDemo
abstract class Car
public abstract int Speed { get; }
abstract class CarFactory
public abstract Car ShowCar();
//Concrete is nothing but the implementaion for the absract classes
class ConcreteCar : Car
int _speed = 300;
public override int Speed
get { return _speed; }

class ConcreteCarFactory : CarFactory
public override Car ShowCar()
return new ConcreteCar();

class CarCompany
public void ProduceCar(CarFactory objfac)
Car mycar = objfac.ShowCar();
Console.Write("Car Produced with speed: " + mycar.Speed);
class Program
static void Main(string[] args)
CarFactory mycarfactory = new ConcreteCarFactory();
new CarCompany().ProduceCar(mycarfactory);

Here the abstract classes Car and CarFactory provides the interface and the classes ConcreteCar and ConcreteCarFactory provides the implementation for the abstract classes. The CarCompany class uses all these to make the factory work.
In the simillar way you can create as many of Cars with different model like RollsRoye, Honda and there by creating classes for them by inheriting the classes Car and CarFactory.
But remember that the CarCompany class is abstracted from other classes.

Design Pattern Singleton design pattern

Design Pattern Singleton design pattern
Singleton Pattern:
It comes under the category of ‘Creational Pattern’.


It allows a single instance of a class and provides global access to it.

Steps to implement a Singleton Pattern in C#:
1. Create a sealed class.
2. Declare a private variable for that class inside the class.
3. Make the constructor as private.
4. Create a public static property which only returns the instance
5. Inside that use lock() to handle the object instance for supporting multi-threading functionality.

1. Logger
It is primarily used in the areas where single access channel is needed. Logging is an area where it is primarily used.
2. Db Connection
For managing database connections also it is used as there should be only one connection at a time.
3. Configuration Manager
Then configuration managers, which read and write to configuration files, there also Singletons are used.

A Logger example in C#:
Steps to write it:
1. Select Visual studio > Project > C# & Windows Application.
2. Follow the steps given in the steps to write a Singleton class above
3. The complete code of the Singleton Pattern and its usage class are given below :

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
using System.IO;

namespace SingletonDemo
public partial class Form1 : Form
public Form1()

private void Form1_Load(object sender, EventArgs e)
MySingleton sg = MySingleton.Instance;

public sealed class MySingleton
private static volatile MySingleton instSingleton;
private static object objSynformultithread = new Object();

private MySingleton()

public void LogMyError(String msg)
TextWriter twLog = new StreamWriter("c:\\log.txt");

// write a line of text to the file
twLog.WriteLine("Start" + DateTime.Now);
// close the stream

public static MySingleton Instance
if (instSingleton == null)
lock (objSynformultithread)
if (instSingleton == null)
instSingleton = new MySingleton();

return instSingleton;

Explanations over the Program:

Purpose of Sealed:
It prevents derivation which could add instances.

Purpose of Private Static Volatile:
Private, it makes the variable private and so not accessible from outside.
Static, without creating instance (only the instance created inside) we can call with name of the class as MySingleton.variable.
Volatile, makes the instance variable assignment completed before it is accessed.

Purpose of Lock:
It avoids deadlocks, enables multithreaded functionality.

The above program has the function LogMyError which does the logging to the file system. You can change the file name and path wherever you want it to get stored. Moreover it was written for a demo purpose only, so its not that much fuller. You need to add the append functionality to it such that it works as according to your need.

If you do the minor modifications based on your need of logging then it will be a good Logger for any kind of application.
Similarly it can be used for DB Connection, Configuration Management, etc.

Design Patterns Interview questions basic

Design Patterns Interview questions basic
Design Patterns are best proven techniques for a common design problem.
It is only a design technique and not code. Though code is available for almost all design patterns in all popular languages, design patterns mean the design technique alone.
Each design pattern explains a repeated problem, gives standard solution to the problem.

Types of Patterns:Design Patterns are generally classified into three categories, they are:
1. Creational
2. Structural
3. Behavioral

1. CreationalThey deal with object creation. They provide you the best way to create objects based on the current situation.
Singleton, Factory method, Abstract factory, Builder

2. StructuralThey deal with relationship between entities. They provide you the best way to relate entities on various scenarios.
Adapter, Aggregate, Bridge

3. BehavioralThey deal with communication between objects. They provide you the best way to communicate between objects.
Chain of responsibility, Command, Interpreter

Further Classification: Though the above three are the major classification, one more category also exists which may be considered as a sub part of the above. It is:

ConcurrencyThey deal with multi-threaded programs. They provide solutions for multi-thread design problems.
Balking, Double checked locking, guarded suspension

OOP Techniques and Design Patterns:Before going into design patterns, we need to know some of the OOP (Object Oriented Programming) features, which will in turn lead to a better understanding of Design patterns.
Let us now see the OOPs features one by one,

Class: It defines characteristics of a thing and its behavior. It is blueprint from based on which objects are created.
Example: Employee (which will have all the details about the employee like name, id, salary, etc and the methods which describes his behavior like calcSalary(),displaydetails(),etc.

Object: Is an instance of a class. It will be exactly the same as a class but can be assigned values and used whereas a class can’t be used without creating objects.

A feature in which the base class’s characteristics and behavior are derived to the child class also.

A class inherits from a single class.
A class inherits from more than 1 class.

Abstraction: “Abstraction is simplifying complex reality by modeling classes appropriate to the problem, and working at the most appropriate level of inheritance for a given aspect of the problem.” Is what the Wikipedia says.

Encapsulation: It is a feature which hides data and functions from others classes.

Polymorphism: A feature using which more than one definition is given to a single name. It can either be function polymorphism or operator overloading.

Association: Association defines a relationship between classes of objects which allows one object to cause another to perform an action on its behalf.

Composition is a way to combine simple objects or data types into more complex ones.

Aggregation: Aggregation is a form of composition where one looks at the system as a whole rather than as parts. 

Tips for Software Test Plan Document

Tips for Software Test Plan Document
In this article, we are going to look at creating software system test plans that really make a difference, in an easy, step-by-step way. We will cover the three main aspects you need to consider as part of software test planning, also a 12 point checklist that should be addressed in all software test plans.
1.    What Kind of information we should put in the software test plan.
2.    Where we can find the right information for your software test plan.
3.    How to get people to act based on your software test plan

What information should I include in the test plan?

Key 1 describe a clear objective:
The main aim of writing a test plan is so you and your team can achieve a specific objective (or goals). The aim is clearly to convey the information necessary to get all of your teams bringing in the same direction to achieve that goal quickly and  efficiently. Whenever you cannot identify your goals clearly, or if you’re not clear on your goals in the first place, then  you should not waste your time writing a test plan yet. Once you’ve outlined your goals, then tell them clearly at the start  of the test plan document.
Key 2 Follow the IEEE Test Plan Recommended format:
The IEEE Standard 829 is a standard that specifies a set of Software Test Documentation. The IEEE 829 standard designs to  depict a set of basic software test documents that can be used to convey a test approach. Within that you will find a  standard template that provides a suggested list of items your test plan should include. You will find a lot of valuable
articles on the Internet that cover the details of an IEEE 829 test plan, but two of the most valuable are:
1)    http://en.wikipedia.org/wiki/IEEE_829
2)    http://online.gerrardconsulting.com/iseb/otherdocs/ieee829mtp.pdf
Briefly, the items that should be covered in an IEEE 829 compliant test plan are as follows:
1.    TEST PLAN IDENTIFIER This is some kind of unique, company-generated number that will identify your test plan, its level, and the version of
software that it is related to.
2.    REFERENCES List all documents that support your test plan. Documents that can be referenced to include: the Project Plan, Requirements
Specifications, High Level Design Document, etc...
3.    INTRODUCTION State the purpose of the plan, and possibly identify the level of the plan (master, system, etc...).
4.    TEST ITEMS (Functions) These are the things you intend to test within the scope of your test plan.
5.    SOFTWARE RISK ISSUES Identify what software is to be tested and what critical areas might present some inherent software risks. One example is the
complexity of a particular module in the application under test.
6.    FEATURES TO BE TESTED This is a listing of what is to be tested from the user point of view.
7.    FEATURES NOT TO BE TESTED This is a listing of what is NOT to be tested from both the User viewpoint and a configuration management / version control
8.    Approach (STRATEGY) This is your overall testing strategy for the test plan, and should detail the rules and processes that will be followed
(e.g. What kind of testing metrics would be collected?).
9.    ITEM PASS / FAIL CRITERIA What are the completion/exit criteria for this plan/system testing? This can be based on the number of test cases completed, the functional/non functional test coverage provided and /  or the level of open bugs identified in the application.
10.    SUSPENSION CRITERIA AND RESUMPTION REQUIREMENTS It should be stated clearly “that, in certain scenarios, testing will be suspended. You must list down what criteria must be met for the testing to resume.
11.    TEST DELIVERABLES What is to be delivered as part of this plan? This consists of the test plan document, test cases, test design specifications, etc...
12.    TEST TASKS This section may contain descriptions of test. Those tasks that need to be completed by internal and external groups.
13.    ENVIRONMENTAL NEEDS Are there any special requirements for this test plan, such as special hardware or static generators?
14.    STAFFING AND TRAINING NEEDS How much time is required to complete the test effort, and what kind of training on the application / system is required?
15.    RESPONSIBILITIES Who is in responsible for completing each section of this test project?
16.    SCHEDULE This will consist of a detailed list of resources who will work on this project and the total testing effort needed. 17.    PLANNING AND RISKS Contingencies What are the overall risks to the project? Put an emphasis on the testing processed here.
18.    APPROVALS Who can, and will, approve the process as complete and allow the project to proceed to the next level?
19.    GLOSSARY The Glossary is used to define terms and acronyms used in the document, and testing in general, To eliminate confusion and  Promote more consistent communications.

Key 3 What a test plan is not:
A significant number of people in software development, product development, testing and the arena itself seem to think that  a test plan is a series of test scripts or test cases.
So, let’s start by saying categorically that a test plan is NOT a collection of tests scripts or test cases.
Generally, a test plan is a written document utilized to describe the course of action to help Achieve a testing goal. A test plan is unquestionably NOT just a list of test cases/scripts. This confusion is one reason why the IEEE defined the IEEE 829 standard.

Conduct background research on the nursing employer
Familiarize yourself with the employer before the interview. You want to discover all you can about the target nursing job. The knowledge you gain before you arrive for the interview will give you the confidence and skills to convince the employer that you are the best nursing candidate.

Research the facility/hospital/unit and the nursing job in question. Learn more about their goals and values, their future plans and direction, the organizational structure, the demands of the job, the patient base. Use this information to prepare good answers to the nursing interview questions you can expect and to list some insightful questions to ask in your nursing job interview. If you're interviewing for a hospital job, research its financial status and economic stability. Is there potential for growth? Find out the the reputation of the hospital in the local community and the medical community.

Various methods can be used to conduct this background research. You can simply "Google" the organization and note down relevant information. Ask people you know who have had some interaction with the employer. If possible you should visit the hospital or medical facility before your interview. You can observe for yourself and ask the nurses and health care staff questions about the patients, management and organization. This also gives you a practice run to make sure you know how to get to the employer and how long it will take you before the day of the actual interview.
Bring the correct documentation
When you go to the nursing job interview, take along extra copies of your resume or CV, your complete and typed list of references, your nursing license and qualifications, and any letters of recommendation you have.

Bring your list of prepared questions to ask and a pen and paper to write down any questions that occur to you during the interview.

Prepare good interview answers
You can expect your nursing job interview to explore a number of areas. These include:

* Your training and qualifications
* Your previous work experience
* General nurse interview questions
* The key competencies required for the nursing job
* Your motivation for this nursing job
Have a list of questions prepared to ask the employer
Prepare a list of relevant questions to ask the employer. This will set you apart as both prepared and professional. Avoid questions that can be answered by conducting a little background research on the company. Your questions should be insightful and reinforce your commitment and enthusiasm for a nursing career.
Dress professionally
Choose the appropriate interview clothing. You want to look professional and make an excellent first impression. For a nursing job the safest option is something business-like and formal. As a nurse it is important to portray the image of a trusted and competent professional.

A pantsuit, dress or skirt with jacket teemed with low-heeled closed shoes would be considered appropriate. Make sure all your interview clothes are clean, well-pressed and tidy. Attention to these sort of details are essential for a nursing professional.

Opencv Compiling and installing for Gumstix

Opencv Compiling and installing for Gumstix
It's common sense that OpenCV is one of the best computer vision libraries available nowadays and it's certainly very useful to benefit from it in embedded environments. There's a trade-off between locally processing images and uploading them for remote processing, but some algorithms might as well run smoothly on embedded devices.

In order to compile OpenCV for Gumstix, firstly one needs to download it from:

The version I've testes was opencv-linux 1.1pre1, but I believe any other release will barely follow the same ideas provided here.
After the file has been extracted (tar -xzvf opencv-1.1pre1.tar.gz), one should configure the environment variables for the compiler:

export CC=/home/developer/gumstix/gumstix-oe/tmp/cross/bin/arm-angstrom-linux-gnueabi-gcc
export CXX=/home/developer/gumstix/gumstix-oe/tmp/cross/bin/arm-angstrom-linux-gnueabi-g++

$ ./configure --host=arm-linux --build=i686-linux --prefix=/home/developer/opencvgum --without-gthread --without-gtk --without-python --disable-apps

Notice that we've defined that the prefix=/home/developer/opencvgum is the place it will be installed when we type 'make install'. By the way, make sure you have created this directory.
Be sure to substitute the /home/developer path to your user path, as well as the /gumstix/gumstix-oe/ to your installed gumstix environment.
We've also disabled the gtk environment since we are not interested in running the GUI applications inside the gumstix. I've also disabled python and building the applications.
Now that configuration has been successful. Type:

$ make

And then:

$ make install

If everything went well, you'll have the binaries and samples installed to /home/developer/opencvgum
Now, it would be useful to try and compile the samples so that we are sure they will run in the Gumstix.
In order to build them, go to /home/developer/opencvgum/share/opencv/samples/c and edit the build_all.sh script.
Make it executable:

$chmod +x ./build_all.sh

And then change all gcc and g++ to its arm-likes. My build_all.sh ended up like this:
export PKG_CONFIG_PATH=/home/developer/opencvgum/lib/pkgconfig/

if [[ $# > 0 ]] ; then
base=`basename $1 .c`
echo "compiling $base"
/home/developer/gumstix/gumstix-oe/tmp/cross/bin/arm-angstrom-linux-gnueabi-gcc -ggdb `pkg-config opencv --cflags --libs` $base.c -o $base
for i in *.c; do
echo "compiling $i"
/home/developer/gumstix/gumstix-oe/tmp/cross/bin/arm-angstrom-linux-gnueabi-gcc -ggdb `pkg-config --cflags opencv` -o `basename $i .c` $i `pkg-config --libs opencv`;
for i in *.cpp; do
echo "compiling $i"
/home/developer/gumstix/gumstix-oe/tmp/cross/bin/arm-angstrom-linux-gnueabi-g++ -ggdb `pkg-config --cflags opencv` -o `basename $i .cpp` $i `pkg-config --libs opencv`;
Notice that we've also defined the export PKG_CONFIG_PATH=/home/developer/opencvgum/lib/pkgconfig/ so that the correct includes and linked libraries are built correctly.
Run this command and you'll notice the executable files will be created. I think that if you don't disable the flag "--disable-apps" in the configure application and make this change to the build_all.sh earlier it might also work.

Well, now that OpenCV has been built, you should be able to copy it to your gumstix. There's a small problem though. If you compact the files, you'll notice it's very big, so, a good idea is to delete a couple files we are sure we are not going to use.
An advice would be to delete some of the haarcascades.

Choose some of them you are sure you won't use, like the haarcascade_profileface.xml inside the data sub-directory, for instance. Delete a couple others as well.
This way, you'll be able to create a .tar.gz of around 6.5MB.
When it's done, copy it to your gumstix through scp:

$scp opencvgum.tar.gz root@192.168.YOUR-GUM.IP:/tmp

Make sure you copy it to /tmp, because you'll probably be out of space copying it somewhere else.
Extract it and then try to run one of the demos that does not use windows... the ./letter_recog application, for instance... it's located at:

Well, you might be able to see it running. Else, some libstdc++.so is missing error could also happen.
This means you don't have this library installed. One easy way to install it is through the command

$ipkg install libstdc++6

In case some other libraries are missing as well, repeat the procedure with their names. Notice that some packages have odd names.
For instance, if you had typed:
$ root@gumstix-custom-verdex:/usr/share$ ipkg install libstdc++

Then you'd have received the following message:

Nothing to be done
An error ocurred, return value: 4.
Collected errors:
Cannot find package libstdc++.
Check the spelling or perhaps run 'ipkg update'

Actually the name of the library is libstdc++6. Make sure you type the correct library name.

Well, in case libstdc++ is really installed, you might as well get some error like:

./letter_recog: error while loading shared libraries: libcxcore.so.2: cannot open shared object file: No such file or directory

It means the LD_LIBRARY_PATH is not pointing at your opencv libraries.
Simply type:

$ export LD_LIBRARY_PATH=/tmp/opencvgum/lib/

You will eventually be able to run your letter_recognition application.
Well, in case you want to run other applications, like the face recognition one, make sure you disable the GUI related functions and write your results to files.
