Proxy Setting is Grayed out

Follow this Blog

I have  a faced  a problem that suddenly one day my proxy setting is grayed out and i cant able to choose my  proxy to access few websites that are blocked. So from surfing i have figured out an workaround to enable proxy in my System.
Steps to Do:-

• Open Registry Editor in your PC. to do so open run command and type "regedit" and select Enter, it will open Registry  Editor Window
• In that go to HKEY_LOCAL_MACHINE=>SOFTWARE=>Policies=>Microsoft=>Windows=>Internet Settings
• When you click Internet Settings on the right hand side, you can see value name  "ProxySettingsPerUser"  , if the Data of that Name is 0, then change it to 1. To change that, make a right click on that item, select Modify and change it to 1. In case if the value is already one and your proxy is grayed out, then you can delete it  and restart your computer.
• Your Proxy settings wont be grayed out.
• To anable proxy settings, type inetcpl.cpl in run command and you can Internet Options Popup, there under Connections Tab => LAN Settings and enable your Proxy.

Step 3: Anytime you want to switch to the older compose mode, select the option Switch Back to Old Compose under More.

The main change is that the compose mail appears at the bottom of the like an horizontal pane and it is quite similar to composing a new message.

I was interested in learning Scripting languages. When i discussed this with my friends they suggested me to learn Python, because its more powerful in scripting languages. I don't know even basic knowledge on scripting languages, so i started gathering documents for learning Perl..

Here there is a link which says Learning Perl , which gives the brief introduction about Perl and the basics of scripting languages.
But now i am searching for an IDE[Editor] for the Perl.
Please suggest me some editors for scripting languages, which would be helpful for me to work with

Constructor Chaining in JAVA

When you try to make an object of the subclass type, it will be running all the constructors in the inheritance tree.
Please see the below example...

public class Animal {
public Animal(){
System.out.println("Animal Constructor");
}
}

public class Hippo extends Animal {
public Hippo(){
System.out.println("Hippo Constructor");
}
}

public class ConstructorChainingTest {
public static void main(String[] args){
Hippo h = new Hippo();
}
}

If you run ConstructorChainingTest .java, the output would be
Animal Constructor
Hippo Constructor..

This is called Constructor Chaining in JAVA

Short Circuit Operators

&& and || are called short circuit operators. These operators are used for "AND" and "OR" operation respectively.
Ex.
if(a && b), Suppose if  a is false, it wont even check the value of b, it skip the condition itself. Take an another example:
if(refVal!=null && refVal.isValid() ) ,
 in this consider refVal is the reference variable and it has not been assigned to any object, so the value of refVal=null, so if its checking refVal.isValid(), it will throw the NullPointerException. Since, the first condition is false, it skips the second condition.

Bug in Google Chrome

We have worked in many browser. To my knowledge, Google chrome was the best one that i have ever seen. Its so fast, very good animation, transparency... But there is a major bug in that.

• In Google chrome, if you open multiple tabs, if the user accidentally closed the window, it closes all the tabs without any prior warnings, it closes all the tabs
• Through this post, i request the  developers team of Google chrome to fix this bug, by throwing the warning message if more than one tabs are opened and if the user is trying to close the window.
