My proposal on implementing C14N based on Axiom for Google Summer of Code 2007 has been accepted. Wow! I really feel excited. Thanks specially for Ruchith Fernando for being the mentor of this project. Thanks for everyone else as well who thought to give a vote for the proposal.

ADSL is Up and Running

Ah! I was able to configure the ADSL router at last. The username and password provided by the ISP did not work. Can you believe it? I was astonished when I received the "authentication failed" error. The 24hr help center, however, gave me the clue to change the password. Luckily I had a dial-up connection as well. At last it worked. Gosh! what a fun it is to play with something new.

I was searching for a free and easy-to-use DVD to AVI converter today. Check this out. It is very impressive.

I was searching for a simple tool to convert OpenOffice word documents to pdf. Then I found this site which simply converts files between a number of different formats. It even keep the file hosted for 24 hours free.

Kandy Trip

I was searching for this photo yesterday because this was the best trip that I went with my good old buddies. This was right after our A/L exams in 2003.

I was able to configure my graphics card (ATI X1300 Raedon Mobility) on my Dell Inspiron E1505 laptop from this nice link. However, I was bugged with the error "Xlib: extension "XFree86-DRI" missing on display ":0.0".". Then I found out that deactivating the composite extension in /etc/X11/xorg.conf would do the job.

Here's what I did from the beginning:

sudo apt-get update
sudo apt-get install xorg-driver-fglrx
sudo apt-get install linux-restricted-modules-2.6.17-10-generic
sudo depmod -a
sudo aticonfig --initial
sudo aticonfig --overlay-type=Xv

Now edit the /etc/X11/xorg.conf to include following three lines

Section "Extensions"
     Option      "Composite" "0"
EndSection

Note: You need to have root privileges to edit this file. So use the command sudo vim /etc/X11/xorg.conf

Then add the following line to /etc/modules

fglrx

Note: You need to have root privileges to edit this file. So use the command sudo vim /etc/modules

Finally press ALT+CTRL+Backspace to restart XServer

Type fglrxinfo in a terminal to verify your installation. You should see something like this

display: :0.0  screen: 0
OpenGL vendor string: ATI Technologies Inc.
OpenGL renderer string: ATI Mobility Radeon X1300 Generic
OpenGL version string: 2.0.6011 (8.28.8)

Now it's DONE :)

Setting up ATI Raedon X1300 (128MB) for Ubuntu Edgy on Dell Inspiron E1505

I was trying to configure my graphics card in Ubuntu Edgy and I found this blog which explained the procedure in a nutshell. However, there is a link to setup repositories which directs to a lengthy page. So to get it done in a nutshell too follow this link.

public class MyThreadExtendingThread extends Thread{
public void run(){
for(int i = 0; i < 100000; i++){
System.out.println("child 1 says - " + i);
}
}
}

public class MyThreadImplementingRunnable implements Runnable{
public void run(){
for(int i = 0; i < 100000; i++){
System.out.println("child 2 says - " + i);
}
}
}

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

/* Ok think of a thread as a child in your class. You ask the child
to count from 0 to 100000. You as the teacher starts counting with the child.
But you two count on two different "threads" so you don't have to wait till
the kid is finish counting.

Let's see this in java - run and see
*/

//MyThreadExtendingThread extends java.lang.Thread class
MyThreadExtendingThread t1 = new MyThreadExtendingThread(); // create a kid to count
t1.start(); // ask the kid to start his job (in this case counting)


/*MyThreadImplementingRunnable implements java.lang.Runnable interface
so if you have to create an instance out of java.lang.Thread class
and pass an instance of your MyThreadImplementingRunnable to it. Then call start()
method of the java.lang.Thread instance
*/
Thread t2 = new Thread(new MyThreadImplementingRunnable()); // create another kid
t2.start(); // ask the kid to start his job (in this case counting)

// you also start counting
for(int i = 0; i < 100000; i++){
System.out.println("Teacher says - " + i);
}
}
}

Internship at WSO2

Tragedy struck for entire world when passenger air planes were used as "bombs" to attack USA. But for my part of the story I started my internship at WSO2, Inc. exactly after 5 years.

It's the fourth day of my training and the most interesting thing is that all the team members are so helpful and friendly. Wow what a relief to be with such great spirits.
