Microsoft on May 28 2009 introduced their new search engine named bing,which will be available world wide at www.bing.com from June 3rd.

What’s new in this search engine? question may go through our mind. Microsoft Bing Team as the answer saying ,

We took a new approach to go beyond search to build what we call a decision engine. With a powerful set of intuitive tools on top of a world class search service, Bing will help you make smarter, faster decisions. We included features that deliver the best results, presented in a more organized way to simplify key tasks and help you make important decisions faster.

Let’s wait and see in the coming days the fight between Bing(Decision Engine) Vs King(Google Search Engine).

you can find more information on bing from discoverbing.com and decisionengine.com .

We would be curious to know who is sharing our IP in our shared hosting package.Here is a way to know that,Axandra free seo tool makes the task easy.

Not everybody can go for a dedicated IP which are better.So atleast we will know our neighbour’s which is good for some specific reasons,such as :-

• To check websites hosted on our server are not spammer.
• To check if porn websites are hosted on the same server we are sharing.
• To check with others to clarify if there is a downtime in our shared server.

To look in a postive side we can also make friends with whom we are sharing our IP.

Thread is a line of execution.In a single-threaded system there is only one execution line (i.e) only one part of program is in the process of execution at any one time

To create a new thread:

Thread mythread = new thread(this);

this referes the current applet & mythread is a variable

Example:

import java.awt.*;
import java.applet.Applet;
public class MovingBall extends Applet implements runnable
{
Thread mythread=null;
int position=0;
public void start()
{
mythread=new Thread(this);
mythread.start();
}
public void run()
{
while(true)
{
for(position=0;position) {
repaint();
try
{mythread.sleep(100);
}
catch(InterruptedException e)
{
}
}
}
}
public void stop()
{
mythread.stop();
mythread = null;
}
public void paint(Graphics g)
{
g.setColor(Color.gray);
g.fillOval(position,50,30,30);
g.setColor(Color.black);
g.fillOval(position+6,58,5,5);
g.fillOval(position+20,58,5,5);
g.drawLine(position+15,58, position+15,68);
g.drawLine(position+12,68, position+15,68);
g.drawLine(position,45,30,30,-50,-70);

Scalable Vector Graphics (SVG) is a XML based language for describing 2D (two dimension) graphics, both static and dynamic.

SVG is an open standard developed by W3C (World Wide Web Consortium). Since the SVG images are defined in XML, they can be searched, indexed, compressed. SVG images can be edited using any text editors.

All major web browsers except Internet Explorer supports and renders the SVG images. Internet Explorer needs a plugin for rendering SVG images.

SVG allows 3 types of graphics:

1. Vector Graphics

2. Raster Graphics

3. Text

A typical SVG image’s xml look like

<?xml version="1.0"?>
<!DOCTYPE svg PUBLIC "-//W3C//DTD SVG 1.1//EN"
         "http://www.w3.org/Graphics/SVG/1.1/DTD/svg11.dtd">
<svg xmlns="http://www.w3.org/2000/svg"
     xmlns:xlink="http://www.w3.org/1999/xlink">
  <polygon fill="red" stroke-width="10" fill-opacity="0.4"
           points="350, 75 379,161 469,161 397,215
                   423,301 350,250 277,301 303,215
