Ruby and its ease or toughness to learn?

Is having a loosely typed language necessary for creating ease of programming?

 

I have worked in programming languages such as c, c+=, java, php, jsp etc. I was trying to study ruby deeply. It looks like if you are a fan of programming systematically and sticking to some standards, ruby might give tough time in making you understand its loosely typed programming manners.

 

Although, a couple of things are fine. But on a whole, I still want to remain with tougher programming languages.:)

Nice one on Yoga Asanas

Why are we so different?

I keep wondering about how each one of are so different inspite of the fact that all of our lives run based on that tickling heart beat which is exactly same in everybody?

 

Well, at times, I come to a conclusion that all of us are born equally at birth with absolutely same behaviour, same features(different for females), same expression etc. But as time go by, we actually become embodiment of our observations, our learning, our experiences. Thats where we start differing in same topic, towards same food, towards same god!

 

I do not know if this is nature design to make world go like this.

 

I am so much puzzled.

Smart coding or what?

Take a look at the following piece of code. Isn't it interesting to find a new Thread class instantiated and on which start is invoked right away. Make a notice of run method. Is that a smart way of coding or displays lazy manners of the programmer.

private void execute(final Request request) {
      new Thread(new Runnable() {
         public void run() {
            request.execute();
         }
      }).start();
   }

Class Inheritance example in Ruby

Following is an example of class inheritance in ruby programming. Do make notice of use of super and "<" for inheritance.

 

class HelloParent

    attr_accessor :name

    def initialize( name )
        print "\nThis is a parent program, Hello #{name}"
        @name = name
    end

    def sayHello
        print "\nI am asked to say Hello #{@name}"
    end
       
end

class HelloChild < HelloParent
    def initialize( name, surname )
        print "\nI am a child class #{surname}"
        super(name)
    end
end

child = HelloChild.new( "Ak", "Kumar" )
child.sayHello

 

In avove try putting something like following:

 

child = HelloChild( "Ak", "Kumar" )

child = new HelloChild( "Ak", "Kumar" )

 

 

And you get the following error:

 

hw2.rb:21: undefined method `HelloChild' for main:Object (NoMethodError)

Yet another Ruby Hello World Program

Trying hello world program once again

 

class Helloworld

    def initialize( name )

        @name = name

    end

 

    def setName(a_name)

        @name = a_name

    end

 

    def getName()

        return @name

    end

end

 

h = Helloworld.new( "Krish" )

puts h.getName()

h.setName( "Aiyana" )

puts h.getName()

 

 

Save the file with any name and extension as *.rb unlike java where top level class name has to be same as file name. Then execute the following command:

 

ruby name.rb

 

NOTE:

 

Do not forget to name the class with first letter as capital letter.

I didnt put the first letter of class name as capital letter and got the following error:

 

hw.rb:1: class/module name must be CONSTANT

Menier's disease and Yoga


I am suffering from Vertigo based disease which they call Menier’s disease. Doctors have given up saying there is no definitive treatment in medicine side. I am going to try homeopathy.

However, I am also planning to join a Yoga class. I read some article on the net which says there are numbers of yoga asanas which could provide great relief to those suffering from vertigo, more specifically rotational vertigo.

Following is the list of those yoga asanas:

1. Malasana
2. Salamba Sirsasana
3. Halasana
4. Paschimottanasana
5. Sanmukhi Mudra
6. Nadi Sodhana Pranayama
7. Savasana

This one is Malasana.

Chilkur Temple, Hyderabad

I went to Chilkur temple today. Well, one of the ways to go to Chilkur temple is go to Medhipatnam bus stand by any means. From there, one could get shared auto-rickshaw, private auto rickshaw or APSRTC buses.

Anyways, it was around 3 hours stay in Chilkur. I had darshan of Balaji as well as lord Shiva. A popular faith is following: go to temple, make 11 rounds around the god’s place and wish one thing. If that gets completed, you have to make 101 rounds the next time you go to Chilkur temple.

Hello World program in Ruby

class HelloWorld
    def initialize( name )
        @name = name
    end
    
    def getName
        return @name
    end
end

Then try the following:

h = HelloWorld.new( "a kumar" )
h.getName

The above prints "a_kumar"

Netbeans Vs Eclipse Vs IntelliJ

I am using NetBeans these days as my Java programming IDE. It is quite cool. I recommend it to all java programmers to try the NetBeans as this is a cool IDE. This could be downloaded from http://www.netbeans.org

The latest version of NetBeans version 5.5 has come with upgraded features. I specially liked the ease of project creation in NetBeans wherein the wizard used for creation project is very good. Later, if you are used to other IDEs, you could configure keys to suit your needs.

Although it is comparatively slower than other IDEs, however it is promising. I give it 8/10. :) Do you really care my readings? Else try for yourself.

Why a new language like "Ruby"?

I just went through the documentation of Ruby language and found myself wondering about why at all we need a new language “Ruby” when we already have so many of them.
