1) Code your Server.js - Node.js main file

i) Importing libraries

 var http = require("http");
 var url = require('url');
 var fs = require('fs');
 var io = require('');

ii) Create Server and Handle Request

var server = http.createServer(function(request, response){
 var path = url.parse(request.url).pathname;
  case '/':   
   fs.readFile(__dirname + "/index.html", function (error, data) {
    if (error) {
     response.write("opps this doesn't exist - 404");
     response.writeHeader(200, {"Content-Type": "text/html"});  
     response.write(data, "utf8");
  case '/socket.html':
   fs.readFile(__dirname + path, function (error, data) {
    if (error) {
     response.write("opps this doesn't exist - 404");
     response.writeHeader(200, {"Content-Type": "text/html"});  
     response.write(data, "utf8");
   console.log(path +"- Not found");
   response.write("opps this doesn't exist - 404");

iii) Play with to do MultiChatting

var serv_io = io.listen(server);
var textarea="";
var name="";
serv_io.sockets.on('connection', function(socket){
 //send data to client
        socket.emit('date', {'date': getCurrentTime()}
    }, 1000);
 socket.on('client_data', function(data){
  //socket.emit('textarea', {'textarea': data.textarea});

function emitData(socket){ 
  {'date': getCurrentTime(),
   'name' : name,

function getCurrentTime(){
 var d = new Date();
 var curr_date = d.getDate();
 var curr_month = d.getMonth()+1;
 var curr_year = d.getFullYear();
 var curr_hour = d.getHours()%12 +"";
 var curr_min = d.getMinutes() + "";
 var curr_sec = d.getSeconds() + "";
 if(curr_hour.length == 1)
 if(curr_min.length == 1)
 if(curr_sec.length == 1)
 //var dateString = sprintf("%2s-%2s-%s %2s:%2s:%2s ",curr_date,curr_month,curr_year,curr_hour,curr_min,curr_sec);
 var dateString = curr_date + "-" + curr_month + "-" + curr_year + "  " + curr_hour +":"+ curr_min +":"+ curr_sec;
 return dateString;

2) Develop Webpage with Socket Javascript

    <script src="/"></script>
 <script src=""></script> 
  width: 200px;
  height: 30px;
  padding-left: 10px;
  color: green;
  var socket = io.connect();
  socket.on('date', function(data){
  socket.on('message', function(data){   
   if(len > 0){
   if ( event.which == 13 ) {
    strname = $('#name').val();
    if(len > 0){
     socket.emit('client_data', {'name':strname,'textarea': message}); 
 function printMessage(strname,message){
  $('#messagearea').html($('#messagearea').html()+"<br/><span style='color:blue;font:18px;'>"+strname+"</span> : "+message);

Are we trusting Google too much?

Are we trusting Google too much?

1. why should chrome warn us with a message when we clear browsing history?

Whenever we try to clear browsing history, chromes tells that there is incognito mode to use, is Google worried if you clear your entire browsing history from chrome?

What does Google do with your browsing history?
Here's a clear evidence, "YouTube", Google's YouTube shows video contents relevant to our browsing history stored in chrome. that's how your information is used to make you use their product(YouTube) more than what you do normally.
you can find the difference when you go to "YouTube" home page in both conditions
1. first without browsing history - everything cleared in chrome- visit YouTube home page
2. after doing couple of Google searches, let chrome shows some history and visit YouTube, you will feel the difference

2. why should chrome has separate log in session separating it from other google products.

when you logged in chrome, also when you logged in some of other google product like gmail, when you signout of gmail,chrome logged in session wont go.

chrome separate login session stores all your data ( you can control it by visiting settings, how many of us do that, what about people who doesn't have enough computer experience to change the settings ) user specific data stored in each of our google account right from browsing history to form input data's.

3. How does google map works - showing traffic information in the road we travel.

It does collect our location information including in which speed we are traveling, it collects every one who uses android mobile or signed in to google map atleast once and using some algorithm it gives back.

4. What will happen with Google Glass?


5. Not just above four items, there are lot more things.. like

     At first time when you open Google Chrome, it asks you to sign in with Google account. How many of you signed in without knowing that it is a log in for Google chrome to save your personal browsing data  in your account?
      Many would have no idea initially that it is a log-in specially for Google Chrome. and would have signed in directly thinking it is normal google product sign-in.

 Obviously, we are very much benefited and addicted to all those products, and there are ways we can control sharing our data to a certain level, but how many of us are really concerned about it, going to settings, searching where it is and switching it off?

Google Restricts Labels in blogger (robot.txt)

Google Search restricts Labels (Categories) for all the blogs in Blogger (BlogSpot)

If you see something like this in your webmaster tools, be cool don’t worry for this.

This is because

Reason: Each Label entries are not sub pages, they are just a well framed search query
For example:
When you click the Label – Windows Trick in, the url pointing to that label is this

If you see this url carefully, you can see “/search/” in it, this means it is not actually a new page to be crawled by the Google search bot, it just a search query url, where all the pages yielded by this search query url is already indexed, so it just says it restricts the labels (search query url), but all the pages in your site is already indexed and included in search engine

The main idea behind having labels in the blogs or website, is to make the users comfortable in selecting categories they wished.

What should you do to make safe browsing, when using your friends laptop or using it in any Internet center.?

What should you do to temporarily erase the trace of what you searched for?

Keep the history unchanged, but temporarily disallow saving of histories, cookies, url names and everything.

Here is what you need to do.

Almost All the browsers has a concept called Private Browsing, Private Browsing helps not to save any information like histories, form entries, username, password, cookies, and everything you browsed for, so all the browsing entries can be unsaved for that particular time of browsing
For Chrome Users
1.       Click Settings ( Tool Icon on the top right corner of chrome)
2.       From the drop down, select “New Incognito Window

3.       You will now see a new window with a Detective Agent Logo on Top Left Corner, where you can make private browsing, credit card transactions, experiments, research, and anything that will not saved forever
4.       And when you close it, it goes normal, If you want to do Private browsing again, need to start from first

For Mozilla Firefox Users
1.       Click Firefox Button on the Left top corner
2.       Click “Start Private Browsing
3.       You will receive a alert box, click “Start Private Browsing” once again

4.       There you go, you will now see a new window that has changed color in the Firefox Button on the Left top corner enjoy private browsing, where you can make private browsing, credit card transactions, experiments, research, and anything that will not saved forever

For Internet Explorer Users
1.       Click Safety Menu on the Top right side of the Internet explorer
2.       Select “InPrivate Browsing

3.       There you go, you will now see a new window that has InPrivate icon on the address bar, enjoy private browsing, where you can make private browsing, credit card transactions, experiments, research, and anything that will not saved forever

Renaming Multiple Files

Windows XP Tips and Tricks - Renaming Multiple Files

In your computer, if you want to rename multiple files at once, like an array, this trick will be very useful.

Windows XP lets you rename files in bulk by simply selecting multiple files within Windows Explorer and pressing the F2 key. When you use this feature, the OS applies the name you enter to the first file and applies the same name with a number in parentheses to the other files you selected (the file extensions remain unchanged).

For example, if you select the following files,
* pics.jpg
* notes.txt
* myname.rtf
* music.mp3

and rename the first file (pics.jpg) to sample.doc, XP renames the remaining files as follows:
* Sample (1).jpg
* Sample (2).txt
* Sample (3).rtf
* Sample (4).mp3

Make your own Thumbnail view size in windows

When we browse images in the explorer, the thumbnail size of the picture's is too small or too big and the quality of the thumbnail is not good, it is possible to make our own thumbnail size and make the thumbnails display in high quaility.

To do this it is required to edit the registry, so it is better to make the registry backup.

2. navigate to HKEY_CURRENT_USER\ Software\ Microsoft \ Windows\ CurrentVersion\Explorer

3. create two new DWord Value by right clicking and select "new->DWORD value" and name one as "ThumbnailSize" and other as "ThumbnailQuality"

4. select Decimal Value and set values for both, ThumbnailSize can have values 32 - 256 and Thumbnail Quaility can have values 50 - 100.

5. open any folder and change the view to Thumbnail and see the difference.

Speed up the Start Menu

Trick to Speed up the Start Menu

The Start Menu can be leisurely when it decides to appear, but you can speed things along by changing the registry entry

HKEY_CURRENT_USER/Control Panel/Desktop/MenuShowDelay
from the default 400 to something a little snappier. Like 0.

(to open registry go to Start->Run->type 'regedit'

Open Windows Explorer to a Different Default Directory

Open Windows Explorer to a Different Default Directory

When you open Windows Explorer (by choosing the Window key and "E" simultaneously or by choosing Start, all Programs, Accessories, Windows Explorer), you can change the directory that appears by default.
If you choose Start, all Programs, Accessories, and then right-click on Windows Explorer and choose Properties, you can modify the "Target" directory.
To go to your C: drive, type simply C:\ in the Target box and choose OK. You can also enter a shortcut key on this screen, telling Windows the character or combination of characters you want to type to automatically open Windows Explorer. You can even change the icon or specify that you always want Explorer to open up in full-screen mode.

Change Text on XP Start Button

Step 1 - Modify Explorer.exe File

In order to make the changes, the file explorer.exe located at C:\Windows needs to be edited. Since explorer.exe is a binary file it requires a special editor. For purposes of this article I have used Resource Hacker. Resource HackerTM is a freeware utility to view, modify, rename, add, delete and extract resources in 32bit Windows executables and resource files (*.res). It incorporates an internal resource script compiler and decompiler and works on Microsoft Windows 95/98/ME, Windows NT, Windows 2000 and Windows XP operating systems.

get this from

The first step is to make a backup copy of the file explorer.exe located at C:\Windows\explorer. Place it in a folder somewhere on your hard drive where it will be safe. Start Resource Hacker and open explorer.exe located at C:\Windows\explorer.exe.

The category we are going to be using is "String Table". Expand it by clicking the plus sign then navigate down to and expand string 37 followed by highlighting 1033. If you are using the Classic Layout rather than the XP Layout, use number 38. The right hand pane will display the stringtable. We’re going to modify item 578, currently showing the word “start” just as it displays on the current Start button.

There is no magic here. Just double click on the word “start” so that it’s highlighted, making sure the quotation marks are not part of the highlight. They need to remain in place, surrounding the new text that you’ll type. Go ahead and type your new entry. In my case I used Click Me!

You’ll notice that after the new text string has been entered the Compile Script button that was grayed out is now active. I won’t get into what’s involved in compiling a script, but suffice it to say it’s going to make this exercise worthwhile. Click Compile Script and then save the altered file using the Save As command on the File Menu. Do not use the Save command – Make sure to use the Save As command and choose a different name for the file. Save the newly named file to C:\Windows.

Step 2 – Modify the Registry

!!!make a backup of your registry before making changes!!!

Now that the modified explorer.exe has been created it’s necessary to modify the registry so the file will be recognized when the user logs on to the system. If you don’t know how to access the registry I’m not sure this article is for you, but just in case it’s a temporary memory lapse, go to Start (soon to be something else) Run and type regedit in the Open field. Navigate to:

HKEY_LOCAL_MACHINE\ SOFTWARE\ Microsoft\ Windows NT\ CurrentVersion\ Winlogon

In the right pane, double click the "Shell" entry to open the Edit String dialog box. In Value data: line, enter the name that was used to save the modified explorer.exe file. Click OK.

Close Registry Editor and either log off the system and log back in, or reboot the entire system if that’s your preference. If all went as planned you should see your new Start button with the revised text.
