How to connect MySQL using JDBC.

2011-08-24T03:40:00.000-07:00

I'm going to explain how to connect to MySQL server using JDBC and connector/J. I'm using Eclipse IDE. So first you must have MySQL connector/J. You can download it from http://www.mysql.com/downloads/connector/j/
After downloading extract it. You just want the mysql-*********.jar file.
So if you are using Eclipse I'll show how to add connector later. If you are not there are two ways to add connector. First method is just copy and paste the .jar in to same folder where your .class files are being. Other method is set CLASSPATH. This link will show you how to set the CLASSPATH. http://ac-support.europe.umuc.edu/~arnoldyl/NetBeansTutorials/Setting-Classpath.html
If you are using Eclipse just open the New java project. In there give appropriate name and click next. Click the tab libraries click button Add External JARs. And give the path to mysql-connector-java.jar. And click finish. Now it is OK. Now you can connect to MySQL. Here is some sample code:


import java.sql.*;
public class Main {

	public static void main(String[] args) {

		Connection conn = null;
	        ResultSet rs = null;

		try {
			Class.forName("com.mysql.jdbc.Driver");
			conn = DriverManager.getConnection("jdbc:mysql://localhost:3306/dbname","root","password");
			Statement st = conn.createStatement();
			rs = st.executeQuery("SELECT * FROM emp");
			System.out.println(conn.getCatalog());
		} catch (ClassNotFoundException e) {
			System.out.println(e.toString());
	        } catch (SQLException ex) {
			System.out.println(ex.toString());
	        }

		try {
		     while(rs.next()){
			System.out.println(rs.getInt(1)+"\t"+rs.getString(2));
		     }
                } catch (SQLException e) {
			e.printStackTrace();
		}
	}
}

* To run this code you must have database and some tables in your MySQL sever.

Number to String

2011-08-17T21:29:00.000-07:00

This is a program that converts number to a string. For example 224 is converted to two hundred and twenty four. This program is written using JAVA 1.6 and I used Eclipse IDE. In this program I used 3 classes. Main, Input and NumFinder. Used a simple logic. As a beginner I don't know any advanced methods and pleas comment about any errors and that will be welcome. The Main class:

/**
 * @author Jayanga Kaushalya.
 * This is a test program that converts number to it's literal.
 * Eg: 224 to two hundred and twenty four. This program is written 
 * using Java 1.6

public class Main {
	
	public static void main(String[] args) {

		new Input();

	}
}

The Input class:

/*

 * Using java buffered input.
 */

public class Input {
	
	private String s = null;
	public Input(){

	}
	
	public void getUserInput(){

			BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
			s = br.readLine();
		}
		catch (IOException e){
			System.out.println(e);
		}		
	}
}

Operator Overloading

2011-04-25T22:18:00.000-07:00

Operator Overloading is a concept that uses only in C++. A simple way to say about Operator Overloading is doing or setting to do arithmetic operations( Addition, Subtraction, Multiplication, Division, etc.....) to Objects.If it is a normal variable it is easy to do this operations.( Eg: A = B + Cwhich A,B and C are integers). What happens if A, B and C were Objects. If they are objects they also individually have some variables. So we cant use normal arithmetic to them.Eg:


class test
{
  int a,b,c;

  public:

  void print();
};

Assume that A,B and C are objects of class test. What will happens if we use this kind of operation A = B + C. Program doesn't know what to do in the object. Shall B.a + C.a must assign to A.a or B.a + B.b + B.c must assign to A.a?? Program doesn't know. So we have to tell the program what to do if this happens. That is what called Operator Overloading. This is just a simple definition.The following program is mostly about Operator Overloading. But it contains about friend functions, constructors, destructors and some about function overloading.



//Operator Overloading

#include 
#include 

using namespace std;

class dimension
{
 int x, y, z;

public:

 // Constructos And Destructors

 dimension();
 dimension( int );
 ~dimension();

 // Member Functions

 void display() // Inline
 {
  cout << x << " " << y << " " << z;
 }

 void input();

 // Operator Overloading

 friend dimension operator - ( dimension );
 friend dimension operator - ( dimension, dimension );

 dimension operator + ( dimension );

};

dimension :: dimension()
{
 x = 0;
 y = 0;
 z = 0;
}

dimension :: dimension( int a )
{
 x = a;
 y = 0;
 z = 0;
}

dimension :: ~dimension()
{
 cout << " ";
}

void dimension :: input()
{
 cout << "Enter Values for x, y and z:";
 cin >> x >> y >> z;
}

dimension operator - ( dimension a )
{
 dimension temp;

 temp.x = -a.x;
 temp.y = -a.y;
 temp.z = -a.z;

 return temp;
}

dimension operator - ( dimension a, dimension b )
{
 dimension temp;

 temp.x = ( a.x - b.x );
 temp.y = ( a.y - b.y );
 temp.z = ( a.z - b.z );

 return temp;
}

dimension dimension :: operator + ( dimension a )
{
 dimension temp;

 temp.x = ( x + a.x );
 temp.y = ( y + a.y );
 temp.z = ( z + a.z );

 return temp;
}

void main()
{
 dimension A, B, C, D, E;
 
 cout << "Enter Values For A and B\n";

 A.input();
 B.input();

 C = -A;

 C.display();

 D = A + B;

 D.display();

 E = B - A;

 E.display();

 getch();

}

My first C++ program on the Blog.


#include 

using namespace std;

void main()

{

     cout << "First Program";

}

2011-04-25T22:09:00.000-07:00

I moved to C++ from C. A superset of C language. Bit hard to learn but easy to use after learned. And now I'am working with OO(Object Oriented) concept.

STATTER 1.03.11.1

2011-02-12T08:57:00.000-08:00

This is simple upgrade to STATTER 1.01.11.1. STATTER 1.02.11.1 is a alpha version so i didnt post its code here. This one include some bug fixes and some new additions.

Cancion del Mariachi

Soy un hombre muy honrado que me gusta lo mejor,
por mujeres no me falta ni el dinero ni el amor
Jineteando en mi caballo por la sierra yo me voy,
las estrellas y la luna ellas me dicen donde voy,

Ay, Ay, Ay, Ay
Ay, Ay mi amor
Ay mi morena de mi corazon,

Me gusta tocar guitara, me gusta cantar el "song",
Mariachi me acompana cuando canto me cancion,
me gusta tomar mis copas agua ardiente selo mejor,
tambien el tequila blanco con su saleda sabor,

Ay, Ay, Ay, Ay,
Ay Ay mi amor
Ay mi morena de mi corazon

Me gusta tocar guitarra, me gusta cantar el "song"
Mariachi me acompana cuando canto me cancion,
me gusta tomar mis copas agua ardiente selo mejor,
tambien el tequila blanco con su saleda sabor,

Ay, Ay, Ay, Ay
Ay, Ay mi amor
Ay mi morena de mi corazon,
Ay, Ay, Ay, Ay
Ay, Ay mi amor
Ay mi morena de mi corazon.......!!

English Translation:

Mariachi song

I am a very honest man I like best,
I'm not missing women or money or love
My horse riders in the mountains I go,
the stars and the moon, they tell me where I go,

Ay, Ay, Ay, Ay
Ay, Ay my love
Oh my dark of my heart

I like playing guitar, I like to sing the "song"
Mariachis are my companions when I sing my song,
I like to take my drinks hot water selo better
also the target with your saled tequila flavor

Ay, Ay, Ay, Ay,
Oh Oh my love
Oh my dark of my heart

I like playing guitar, I like to sing the "song"
Mariachis are my companions when I sing my song,
I like to take my drinks hot water selo better
also the target with your saled tequila flavor

Ay, Ay, Ay, Ay
Ay, Ay my love
Oh my dark of my heart
Ay, Ay, Ay, Ay
Ay, Ay my love
Oh my dark my heart .......!!

C Memory Related Functions

2011-01-11T10:25:00.000-08:00

malloc

Allocates a block of size bytes of memory, returning a pointer to the beginning of the block.
The content of the newly allocated block of memory is not initialized, remaining with indeterminate values.
Syntax: (size_t*) malloc(size);
Return type void. If some errors return NULL.

calloc

Allocates a block of memory for an array of number elements, each of them size bytes long, and initializes all its bits to zero.
The effective result is the allocation of an zero-initialized memory block of (number * size) bytes.
Syntax: (size_t*) calloc(size);
Return type void. If some errors return NULL.

realloc

The size of the memory block pointed to by the ptr parameter is changed to the size bytes, expanding or reducing the amount of memory available in the block.
The function may move the memory block to a new location, in which case the new location is returned. The content of the memory block is preserved up to the lesser of the new and old sizes, even if the block is moved. If the new size is larger, the value of the newly allocated portion is indeterminate.
In case that ptr is NULL, the function behaves exactly as malloc, assigning a new block of size bytes and returning a pointer to the beginning of it.
In case that the size is 0, the memory previously allocated in ptr is deallocated as if a call to free was made, and a NULL pointer is returned.

free

A block of memory previously allocated using a call to malloc, calloc or realloc is deallocated, making it available again for further allocations.
Notice that this function leaves the value of ptr unchanged, hence it still points to the same (now invalid) location, and not to the null pointer.

2011-01-05T08:57:00.001-08:00

Mass Effect is an action role-playing game developed by BioWare for the Xbox 360 and then ported to Microsoft Windows by Demiurge Studios. The Xbox 360 version was released worldwide in November 2007 published by Microsoft Game Studios. The Windows version was released on May 28, 2008, published by Electronic Arts.

The game takes place in the year 2183, with the player, assuming the role of an elite human soldier named Commander Shepard, setting out to explore the Galaxy on a starship, the SSV Normandy. The titular mass effect is a form of inertia-suppressing technology, allowing faster-than-light travel.

In addition to a sequel, and plans for a third to add to the trilogy, BioWare plans to release episodic content online to fill in the story between each game, though these episodes are not essential for understanding the main plot line. The first downloadable content package, Bring Down the Sky, was released on March 10, 2008 (with a PC version released on July 29, 2008 ) The second downloadable content package, Pinnacle Station, was released on August 25, 2009 for the PC and Xbox 360.

A sequel, Mass Effect 2, was released on January 26, 2010, and takes place two years after the events that transpired in the first game. Mass Effect 2 also directly uses players' completed save data from the first game to influence events and story lines within the second game, basing certain events and narrative threads on decisions and actions that the player made in the first game.

Mass Effect 3 is the upcoming sequel to Mass Effect and Mass Effect 2 developed by BioWare for the PC, PlayStation 3, and Xbox 360. It is intended to be final game in the planned Mass Effect trilogy. The game was officially announced on December 11, 2010 at Spike's 2010 Video Game Awards. Mass Effect 3 is scheduled for release in "Holiday 2011". Previously Ray Muzyka had stated that release timing would be based on maximising both "quality" and "commercial success".

What Is C

2011-01-03T01:42:00.000-08:00

C is a general-purpose computer programming language developed in 1972 by Dennis Ritchie at the Bell Telephone Laboratories for use with the Unix operating system.
Although C was designed for implementing system software, it is also widely used for developing portable application software.
C is one of the most popular programming languages of all time and there are very few computer architectures for which a C compiler does not exist. C has greatly influenced many other popular programming languages, most notably C++, which began as an extension to C.

Video Game Addiction

2010-09-11T01:52:00.000-07:00

Video game addiction, or more broadly video game overuse, is excessive or compulsive use of computer and video games that interferes with daily life. Instances have been reported in which users play compulsively, isolating themselves from, or from other forms of, social contact and focusing almost entirely on in-game achievements rather than broader life events.There is no diagnosis of video game addiction, although it has been proposed for inclusion in the next version of the Diagnostic and Statistical Manual of Mental Disorders(DSM).

Possible disorder

Video game addiction is not included as a diagnosis in either the DSM or the International Statistical Classification of Diseases and Related Health Problems.

However, the effects (or symptoms) of video game overuse are similar to those of other proposed psychological addictions. Video game overuse may be, like compulsive gambling, an impulse control disorder.

In 2007, the American Psychological Association reviewed whether or not video game addiction should be added in the new DSM to be released in 2012. The conclusion was that there was not enough research or evidence to conclude that video game addiction was a disorder.

Public concern and formal study

A report by the Council On Science And Public Health to the AMA cited a 2005 Entertainment Software Association survey of computer game players and noted that players of MMORPGs were more likely to play for more than two hours per day than other gamers. In its report, the Council used this two-hour-per-day limit to define "gaming overuse", citing the American Academy of Pediatrics guideline of no more than one to two hours per day of "screen time". However, the ESA document cited in the Council report does not contain the two-hour-per-day data.

In a 2005 Tom's Games interview, Dr. Maressa Orzack estimated that 40% of the players of World of Warcraft (an MMORPG) were addicted, but she did not indicate a source for the estimate. She may have derived the estimate from the informal survey managed by Nick Yee at The Daedalus Project,who notes that caution should be exercised when interpreting these data.

A 2006 lecture reported by the BBC indicated that 12% of polled gamers reported at least some addictive behaviours. The lecturer, Professor Mark Griffiths of Nottingham Trent University, stated in another BBC interview that addicts are "few and far between."

In 2007, Michael Cai, director of broadband and gaming for Parks Associates (a media/technology research and analysis company), said that "Video game addiction is a particularly severe problem in Asian countries such as China and Korea." Results of a 2006 survey suggested that 2.4% of South Koreans aged 9 to 39 suffer from game addiction, with another 10.2% at risk of addiction.

A 2007 Harris Interactive online poll of 1,187 US youths aged 8–18 gathered detailed data on youth opinions about video game play. About 81% of youths stated that they played video games at least once per month. Further, the average play time varied by age and sex, from eight hours per week (responses from teen girls) to 14 hours per week (responses by teen boys). "Tweens" (8–12-year-olds) fell in the middle, with boys averaging 13 hours per week of reported game play and girls averaging 10. Harris concluded that 8.5% "can be classified as pathological or clinically 'addicted' to playing video games", but did not explain how this conclusion was reached.

Since the American Psychological Association decision in 2007, studies have been conducted at Stanford University School of Medicine related to video game play. Researchers found evidence that video games do have addictive characteristics.[23][24] An MRI study found that the part of the brain that generates rewarding feelings is more activated in men than women during video game play.

Media coverage

The press has reported concerns over online gaming since at least 1994, when Wired Magazine mentioned a college student who was playing a MUD for 12 hours a day instead of attending class.

Press reports have noted that some Finnish Defence Forces conscripts were not mature enough to meet the demands of military life and were required to interrupt or postpone military service for a year. One reported source of the lack of needed social skills is overuse of computer games or the Internet. Forbes termed this overuse "Web fixations" and stated that they were responsible for 13 such interruptions or deferrals over the five years from 2000-2005.

In a July 2007 article, Perth, Western Australia, parents stated that their 15-year-old son had abandoned all other activities to play RuneScape, a popular MMORPG. The boy's father compared the condition to heroin addiction.

In an April 2008 article, Telegram.co.uk reported that surveys of 391 players of Asheron's Call showed that 3% of the respondents suffered from agitation when they were unable to play, or missed sleep or meals to play. The article reports that University of Bolton lead researcher Dr. John Charlton stated, "Our research supports the idea that people who are heavily involved in game playing may be nearer to autistic spectrum disorders than people who have no interest in gaming."

On March 6, 2009, the CBC's national newsmagazine program the fifth estate aired an hour-long report on video game addiction and the Brandon Crisp story, titled "Top Gun", subtitled "When a video gaming obsession turns to addiction and tragedy".

Governmental concern

In August 2005, the government of the People's Republic of China, where more than 20 million people play online games, introduced an online gaming restriction limiting playing time to three hours, after which the player would be expelled from whichever game they were playing. In 2006, it relaxed the rule so only citizens under the age of 18 would face the limitations. Reports indicate underage gamers found ways to circumvent the measure. In July, 2007, the rule was relaxed yet again. Internet games operating in China must require that users identify themselves by resident identity numbers. After three hours, players under 18 are prompted to stop and "do suitable physical exercise." If they continue, their characters gain 50% of the usual experience. After five hours, their characters gain no experience at all.

In 2008, one of the five FCC Commissioners, Deborah Taylor Tate, stated that online gaming addiction was "one of the top reasons for college drop-outs".[39] However, she did not mention a source for the statement nor identify its position in relation to other top reasons

Possible symptoms

Excessive use of video games may have some or all of the symptoms of drug addiction or other proposed psychological addictions. Some players become more concerned with their interactions in the game than in their broader lives. Players may play many hours per day, gain or lose significant weight due to playing, disrupt sleep patterns to play and suffer sleep deprivation as an effect, play at work, avoid phone calls from friends and/or lie about play time. Relationships with family and friends and performance at work or school may suffer.

Possible causes

Theorists focus on the built-in reward systems of the games to explain their addictive nature. In reference to gamers such as one suicide in China, the head of one software association was quoted, "In the hypothetical world created by such games, they become confident and gain satisfaction, which they cannot get in the real world."

Researchers at the University of Rochester and Immersyve, Inc. (a Celebration, Florida, computer gaming Think-tank) investigated what motivates gamers to continue playing video games. According to lead investigator Richard Ryan, they believe that players play for more reasons than fun alone. Ryan, a motivational psychologist at Rochester, says that many video games satisfy basic psychological needs, and players often continue to play because of rewards, freedom, and a connection with other players.

Michael Brody, M.D., head of the TV and Media Committee of the American Academy of Child and Adolescent Psychiatry, stated in a 2007 press release that "... there is not enough research on whether or not video games are addictive." However, Dr. Brody also cautioned that for some children and adolescents, "... it displaces physical activity and time spent on studies, with friends, and even with family."

Dr. Karen Pierce, a psychiatrist at Chicago's Children's Memorial Hospital, sees no need for a specific gaming addiction diagnosis. Two or more children see her each week because of excessive computer and video game play, and she treats their problems as she would any addiction. She said one of her excessive-gaming patients "...hasn't been to bed, hasn't showered...He is really a mess."

Prevention and correction

Some countries, such as South Korea, China, the Netherlands, Canada, and the United States, have responded to the perceived threat of video game addiction by opening treatment centers.

Because few clinical trials and no meta-analyses have been completed, research is still in the preliminary stages for excessive gaming treatment. The most effective treatments seem to be, as with addictions or dependencies, a combination of psychopharmacology, psychotherapy and twelve-step programs.

China
The Chinese government operates several clinics to treat those suffering from overuse of online games, chatting and web surfing. Treatment for the patients, most of whom have been forced to attend by parents or government officials, include various forms of pain or uneasiness. In August 2009, Deng Sanshan reportedly threw himself off of a roof of a correctional facility for video game and Web addiction after having been beaten and physically and mentally abused.

Netherlands
In June 2006, the Smith and Jones Clinic in Amsterdam became the first treatment facility in Europe to offer a residential treatment program for compulsive gamers.[53] Keith Bakker, founder and head of the clinic, has stated that 90% of the young people who seek treatment for compulsive computer gaming are not addicted. The clinic focuses on excess gaming being a result of social situations rather than an addictive dependency.

United States
McLean Hospital in Belmont, Massachusetts has set up Computer Addiction Services. Elsewhere, gamers may seek services at generalized addiction support centers.

Online Gamers Anonymous, an American non-profit organization formed in 2002, is a twelve-step, self-help, support and recovery organization for gamers and their loved ones who are suffering from the adverse effects of excessive computer game playing. The organization provides a variety of message boards, several on-line meetings and other tools for healing and support.

In July 2009, ReSTART, a residential treatment center for "pathological computer use", opened in Fall City, near Seattle, Washington.

Canada
At a Computer Addiction Services[55] center in Richmond, British Columbia, excessive gaming accounts for 80% of one youth counselor's caseload.

Sri Lanka
In Sri Lanka still there are no such people addicted to games. But it is expeditiously rising. Students who going to GAME CAFES after school is also rising. IF government or some one else didnt do any prevention Sri Lanka also may be need treatment centeres near future.

Notable deaths

Globally, there have been deaths caused directly by exhaustion from playing games for excessive periods of time. There have also been deaths of gamers and/or others related to playing of video games.

China
In 2007, it was reported that Xu Yan died in Jinzhou after playing online games persistently for over 15 days during the Lunar New Year holiday. Later 2007 reports indicated that a 30-year-old male died in Guangzhou after playing video games continuously for three days.

In June 2005, one news agency reported, "Xiao Yi was thirteen when he threw himself from the top of a twenty-four story tower block in his home town, leaving notes that spoke of his addiction and his hope of being reunited with fellow cyber-players in heaven. The suicide notes were written through the eyes of a gaming character ..."

In March 2005, the BBC reported a murder in Shanghai, when Qiu Chengwei fatally stabbed fellow player Zhu Caoyuan, who had sold on eBay a dragon sabre sword he had been lent in a Legend of Mir 3 game, and was given a suspended death sentence.

South Korea
In 2005, Seungseob Lee (Hangul) visited an Internet cafe in the city of Taegu and played StarCraft almost continuously for fifty hours. He went into cardiac arrest, and died at a local hospital. A friend reported: "...he was a game addict. We all knew about it. He couldn't stop himself." About six weeks before his death, his girlfriend, also an avid gamer, broke up with him, and he had been fired from his job for repeated tardiness.

In 2009, Kim Sa-rang, a 3-month-old Korean child, died from malnutrition after both her parents spent hours each day in an internet cafe raising a virtual child on an online game, Prius Online.

Vietnam
An Earthtimes.org article reported in 2007 that police arrested a 13-year-old boy accused of murdering and robbing an 81-year-old woman. A local policeman was quoted as saying that the boy "...confessed that he needed money to play online games and decided to kill and rob..." the victim. The article further related a police report that the murder by strangling netted the thief 100,000 Vietnamese dong (US$6.20).

United States
Press reports in November 2005 state that Gregg J. Kleinmark, 24, plead "guilty to two counts of involuntary manslaughter". He "left fraternal twins Drew and Bryn Kleinmark unattended in a bathtub for 30 minutes, in order to go three rooms away and play on his Game Boy Advance" while "in the mean time, the two ten-months old kids drowned".

Tyrone Spellman, 27, of Philadelphia, was convicted of third-degree murder for killing his 17-month old daughter in a rage over a broken Xbox.

Ohio teen Daniel Petric shot his parents, killing his mother, after they took away his copy of Halo 3 in October 2007. In a sentencing hearing after the teen was found guilty of aggravated murder, the judge said, "I firmly believe that Daniel Petric had no idea at the time he hatched this plot that if he killed his parents they would be dead forever." On 16 June 2009, Petric was sentenced to 23 years to life in prison.

Canada
Brandon Crisp, an Ontario 15-year-old, ran away from home on Thanksgiving Monday in 2008 after his parents took away his Xbox 360 due to falling grades and excessive play of Call of Duty 4: Modern Warfare. He was last seen alive on a bicycle trail. His body was found 3 weeks later, about three miles away, by a party of hunters. An autopsy determined that he died when he fell from a tree.

Sri Lanka
No any deaths reported.

What Is A Programing Language

2010-09-11T01:33:00.000-07:00

A programming language is an artificial language designed to express computations that can be performed by a machine, particularly a computer. Programming languages can be used to create programs that control the behavior of a machine, to express algorithms precisely, or as a mode of human communication.

Many programming languages have some form of written specification of their syntax (form) and semantics (meaning). Some languages are defined by a specification document. For example, the C programming language is specified by an ISO Standard. Other languages, such as Perl, have a dominant implementation that is used as a reference.

The earliest programming languages predate the invention of the computer, and were used to direct the behavior of machines such as Jacquard looms and player pianos. Thousands of different programming languages have been created, mainly in the computer field, with many more being created every year. Most programming languages describe computation in an imperative style, i.e., as a sequence of commands, although some languages, such as those that support functional programming or logic programming, use alternative forms of description

Learn PHP

2010-09-05T13:04:00.000-07:00

I am now learning PHP. Still studying basics but I already have some knowledge in c. So I can learn it quickly.

To do learning first we have to install php in our pc. You can download php for free in here: http://www.php.net/downloads.php.
(Here is a link to a good tutorial from PHP.net on how to install PHP5: http://www.php.net/manual/en/install.php).*

Then you need a web server. You can download apache server for free in here: http://httpd.apache.org/download.cgi.*

Finally you need a database. You can download My SQL for free in hear: http://www.mysql.com/downloads/.*

But it is very much easy if you download WAMPSEVER.
( WAMP is an acronym formed from the initials of the operating system Microsoft Windows and the principal components of the package: Apache, MySQL and PHP (or Perl or Python, although WAMP includes PHP exclusively). Apache is a web server. MySQL is an open-source database. PHP is a scripting language that can manipulate information held in a database and generate web pages dynamically each time content is requested by a browser. Other programs may also be included in a package, such as phpMyAdmin which provides a graphical user interface for the My SQL database manager or the alternative scripting languages Python or Perl.).
You can download wampsever for free in here: http://www.wampserver.com/en/download.php
*(Those are for windows only)

If you have those now you can start learning. I found a free site. http://www.w3schools.com/PHP/default.asp. I think it is great.

I will put some more in future.

I Start It Again.

2010-09-05T12:03:00.000-07:00

I started this blog in 2007 but due to other works and simple understanding about blogging I didn’t continue it. But after Prabath aiya says now it is time to restart your blogging I thought that I should start blogging. So here is my blog…………………….

I don’t have exact idea or exact epigraph to blog. I like to blog about everything but in this blog it mainly consider about IT stuff. Because of I think that I will be doing IT stuff in my future.

If I tell about the header “ASCERTAIN” I put it because it has a meaning that search and understand. I also want to search and understand. What Parbath aiya always saying me don’t ask him, just search Google and find answers. It is hard but I never forget it again. If I ask someone maybe ill forget it and will ask the same question again and again (I have this kind of experience when I am asking questions from Prabath aiya.).

My English knowledge is very much poor. But I think that readers can understand what I am meaning. I’ll try to improve my English knowledge in future.
