2010-04-27T07:12:00.001-07:00

Swanalekha is now available as jQuery plugin. Check it out.

This plugin makes it simple to use Swanalekha in your website/webpage.

Just include the jquery-swanalekha.js in your page and use it.

Some examples :

$("#t_input").swanalekha(); //will enable swanalekha on the element with id 't_input'


$("textarea").swanalekha(); //will enable swanalekha on all textareas

$("input").swanaleka(); //will enable swanaleka on all inputs, but only text inputs will actually be enabled

The Solar eclipse

2010-01-15T02:23:00.000-08:00

We bunked office today and went to Kanakakunnu Palace. It was like a festival there. School kids from all over Kerala had come to witness the Solar eclipse.

This snap was taken through an aluminium foil.

I registered നിഷാന്‍.com[redirected to this site now] recently from domainsite.com. These guys support unicode domain names by converting it to a cryptic string starting with 'xn-'.

May be you would want to register yours before someone else snatches it! :)

Swanalekha firefox add-on

2009-03-22T22:02:00.000-07:00

Swanalekha malayalam transliteration tool has been packaged into a Firefox add-on.

You can install the add-on and type Ctrl-M on any textbox to malayalam-enable it. Right now, this does not work in rich text editors (eg: gmail compose box). I am still scratching my head on how to do that :)

The addon basically wraps the javascript used in swanalekha online. The script was orignally written by Santhosh, thanks to him.

"Mr Darwin, we're sorry", The Church !

2008-09-17T07:16:00.000-07:00

"People, and institutions, make mistakes and Christian people and Churches are no exception. When a big new idea emerges that changes the way people look at the world, it's easy to feel that every old idea, every certainty, is under attack and then to do battle against the new insights.

The Church made that mistake with Galileo's astronomy and has since realised its error. Some Church people did it again in the 1860s with Charles Darwin's theory of natural selection."

You weren't meant to have a Boss

"The average MIT graduate wants to work at Google or Microsoft, because it's a recognized brand, it's safe, and they'll get paid a good salary right away. It's the job equivalent of the pizza they had for lunch. The drawbacks will only become apprent later, and then only in a vague sense of malaise.

And founders and early employees of startups, meanwhile, are like the Birkenstock-wearing weirdos of Berkeley: though a tiny minority of the population, they're the ones living as humans are meant to. In an artificial world, only extremists live naturally."

XStream : The simple XML Parser

2008-08-11T08:45:00.000-07:00

XStream is an xml parsing API implemented in Java. Key things about XStream is that it is very simple, lightweight, easy-to-use and open-source.

Let me show you how to start off with XStream.

Download XStream jar file, and have it in your classpath.

Let's see how to serialize an object into xml using XStream.

We have a class 'Person'

public class Person {
 private String name = "";
 private String address = "";
 
 public String getName() {
  return name;
 }
 
 public void setName(String name) {
  this.name = name;
 }
 
 public String getAddress() {
  return address;
 }
 
 public void setAddress(String address) {
  this.address = address;
 }

}

Here's how we serialize an Object of Class 'Person'

public void writeAsXml() {

 Person person = new Person();
 person.setName("Bob");
 person.setAddress("Georgia");

 XStream xStream = new XStream();
 try {
  FileOutputStream fs = new FileOutputStream("/tmp/person.xml");
  xStream.toXML(person, fs);
 } catch (FileNotFoundException fe) {
  fe.printStackTrace();
 }

}

The xml output we get looks like this:

<Person>
 <name>Bob</name>
 <address>Georgia</address>
</Person>

Easy, huh?

Now going on to deserialze Objects from XML,

public void readFromXml() {
  
 XStream xStream = new XStream(new DomDriver());

 try {
  FileInputStream fin = new FileInputStream("/tmp/person.xml");
  Person person = (Person) xStream.fromXML(fin, new Person());
  System.out.println("Hello "+person.name+", from "+person.address);
 } catch (FileNotFoundException fe) {
  fe.printStackTrace();
 }

}

We can accomplish more complicated stuff using XStream. But for a start I guess this is enough :)

Running Selenium inside JUnit

2008-06-29T16:53:00.000-07:00

Selenium is a framework which makes testing a web application possible, in an automated fashion. It helps us record test scripts in various formats and run it on the web application.
Selenium brings you three components. One of those, Selenium-ide is available as a firefox extension which can record your actions on a web page and then re-run it. Another component called selenium-core helps you copy the test-scripts over to the server and run it from there. This is helpful when you need more control over the way tests are run. Third one, which we are particularly interested in, is the selenium-remote. Selenium-remote has a server and client architecture.

JUnit is a unit testing framework (okay, I know you know that!). It is possible to
combine jUnit and Selelnium to write powerful client side test scripts. One advantage is that selenium testscripts can be made part of your build process.

Now, lets get into action. Download the selenium-remote.

First step would be to run the selenium-server. The server acts as a intercepting server
for the client (the client is mostly the browser).

$java -jar selenium-server.jar
19:18:09.156 INFO - Java: Sun Microsystems Inc. 10.0-b22
19:18:09.156 INFO - OS: Windows XP 5.1 x86
19:18:09.156 INFO - v0.9.2 [2006], with Core v0.8.3 [1879]
19:18:09.500 INFO - Version Jetty/5.1.x
19:18:09.500 INFO - Started HttpContext[/selenium-server/driver,/selenium-server
/driver]
19:18:09.500 INFO - Started HttpContext[/selenium-server,/selenium-server]
19:18:09.500 INFO - Started HttpContext[/,/]
19:18:09.828 INFO - Started SocketListener on 0.0.0.0:4444
19:18:09.828 INFO - Started org.mortbay.jetty.Server@6d084b

Server is up and running on port 4444 (of course you can change the port, take a look at the command line options)

You are now ready for the jUnit test case. A simple one :


import com.thoughtworks.selenium.DefaultSelenium;
import com.thoughtworks.selenium.Selenium;

import junit.framework.TestCase;


public class DummyTest extends TestCase {

    Selenium selenium = null; // selenium object represents the browser
   
        public void setUp() {
                   // Open the browser, connect to selenium server on localhost:4444. the basedomain is www.inapp.com
                  // *firefox is the browser command for Firefox, *iexplore for IE.
                 selenium  = new DefaultSelenium("localhost", 4444, "*iexplore", "http://www.inapp.com" );
        }
   
        public void testDummyFunction() throws Exception {
                selenium.open("http://www.inapp.com"); // open the url in browser
                assertTrue(selenium.getTitle().startsWith("InApp")); // the test!
                selenium.close();
        }
}

Note that you have to specify a base-domain while instantiating DefaultBrowser. A url from another domain cannot be opened from the browser for security reasons.
Dont forget to include selenium-java-client.jar in your classpath.

Lets look at another example :


import com.thoughtworks.selenium.SeleneseTestCase;

public class DummyTest extends SeleneseTestCase { //Notice that we extend 'SeleneseTestCase' instead of 'TestCase'
       
        public void testDummyFunction() throws Exception {
                setUp("http://www.inapp.com", "*firefox");  // initialize the DefaultBrowser
                selenium.open("http://www.inapp.com"); // open the url in browser
                assertTrue(selenium.getTitle().startsWith("InApp")); // the test!
                selenium.close();
    }
}

We make use of SeleneseTestCase provided by selenium remote. It makes the code concise.

The DefaultBrowser class have lot of methods which we can use in order to validate the content in the browser and fire events. You event have a 'captureScreenshot' method to get a screenshot of your browser. So next time you have a test fail, get the screenshot mailed to you :)

The free software movement is a political cause, not a technical one.

2008-03-20T23:14:00.000-07:00

Richard M Stallman writes in emac-devel list.

  What I'm trying to say is: I won't discuss which dVCS we choose
(unless it makes Windows development a PITA). But I agree with Jeremy
Maitin-Shepard that the cause of free software is strengthened by us
selecting among the free alternatives the one that best serves our
technical, not political, needs.

That is completely backwards.  The free software movement is a
political cause, not a technical one.  "Choose based on technical
criteria first of all" is the opposite of what we say.

There are many reasons why GNU packages should support other GNU
packages.

The GNU Project is not just a collection of software packages.  Its
intended result is a coherent operating system.  It is particularly
important therefore that GNU packages should work well with other GNU
packages.  For instance, we would like Emacs to work well with git or
mercurial, but we especially want it to work well with Bzr.

The maintainers of one GNU package should use other GNU packages so
they will notice whether the packages work well together, and make
them work well together.

We also promote use of other GNU packages in this way.
Other people don't necessarily see which editor you use,
but they all see what dVCS you use.

Professors Slam Java As "Damaging" To Students

2008-01-09T20:09:00.000-08:00

"The resulting set of skills [from today's educational practices] is insufficient for today's software industry (in particular for safety and security purposes) and, unfortunately, matches well what the outsourcing industry can offer. We are training easily replaceable professionals... Java programming courses did not prepare our students for the first course in systems, much less for more advanced ones. Students found it hard to write programs that did not have a graphic interface, had no feeling for the relationship between the source program and what the hardware would actually do, and (most damaging) did not understand the semantics of pointers at all, which made the use of C in systems programming very challenging."

I did get three t-shirts from them - but was not able to organize anything.
But I did upload OpenCD in our company's local repository. Hope that will

Liberated from mp3 !

2007-08-06T21:23:00.000-07:00

Today I converted all my mp3 files to ogg !
Ogg is an audio format which is superior to mp3 in quality and compression, and most importantly it is open.Visit http://playogg.org for more details on ogg format.

Wrote a small script for doing that :

MP3=$1
OGG=`dirname $MP3`/`basename $MP3 mp3`ogg

if [ $# -lt 1 ]
then
echo "usage: mp3toogg input.mp3";
else
mpg123 -w - $MP3 | oggenc -o $OGG -
fi

though it took a whole day to convert 10 Gb of my music, I saved 2 GB of space when it was finally done.

A song of despair

2007-08-01T23:12:00.000-07:00

Stumbled upon this beautiful poem once again --

Tonight I can write the saddest lines.

Write, for example,'The night is shattered
and the blue stars shiver in the distance.'

The night wind revolves in the sky and sings.

Tonight I can write the saddest lines.
I loved her, and sometimes she loved me too.

Through nights like this one I held her in my arms
I kissed her again and again under the endless sky.

She loved me sometimes, and I loved her too.
How could one not have loved her great still eyes.

Tonight I can write the saddest lines.
To think that I do not have her. To feel that I have lost her.

To hear the immense night, still more immense without her.
And the verse falls to the soul like dew to the pasture.

What does it matter that my love could not keep her.
The night is shattered and she is not with me.

This is all. In the distance someone is singing. In the distance.
My soul is not satisfied that it has lost her.

My sight searches for her as though to go to her.
My heart looks for her, and she is not with me.

The same night whitening the same trees.
We, of that time, are no longer the same.

I no longer love her, that's certain, but how I loved her.
My voice tried to find the wind to touch her hearing.

Another's. She will be another's. Like my kisses before.
Her voide. Her bright body. Her inifinite eyes.

I no longer love her, that's certain, but maybe I love her.
Love is so short, forgetting is so long.

Because through nights like this one I held her in my arms
my sould is not satisfied that it has lost her.

Though this be the last pain that she makes me suffer
and these the last verses that I write for her.
