Developing your first Node.js Socket io application - Learn Simple Multichat example in Node.js and socket.io.

C

Topics

1) Code your Server.js - Node.js main file
        i) Importing libraries
        ii) Create Server and Handle Request
        iii) Play with Socket.io to do MultiChatting
2) Develop Webpage with Socket Javascript
3) Download Project here


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('socket.io');

ii) Create Server and Handle Request

var server = http.createServer(function(request, response){
 
 var path = url.parse(request.url).pathname;
 console.log('Path='+path);
 switch(path){
  case '/':   
   fs.readFile(__dirname + "/index.html", function (error, data) {
    if (error) {
     response.writeHead(404);
     response.write("opps this doesn't exist - 404");
     response.end();  
    }  
    else{ 
     response.writeHeader(200, {"Content-Type": "text/html"});  
     response.write(data, "utf8");
     response.end();  
    }
   });
   break;
   
  case '/socket.html':
   fs.readFile(__dirname + path, function (error, data) {
    if (error) {
     response.writeHead(404);
     response.write("opps this doesn't exist - 404");
     response.end();  
    }  
    else{ 
     response.writeHeader(200, {"Content-Type": "text/html"});  
     response.write(data, "utf8");
     response.end();  
    }
   });
   break;
   
  default:
   console.log(path +"- Not found");
   response.writeHead(404);
   response.write("opps this doesn't exist - 404");
   response.end();
   break;
 }
 
});
server.listen(8001);

iii) Play with Socket.io to do MultiChatting


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

function emitData(socket){ 
 socket.broadcast.emit('message', 
  {'date': getCurrentTime(),
   'name' : name,
   'textarea':textarea
  }
 );
}

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)
  curr_hour="0"+curr_hour;
 if(curr_min.length == 1)
  curr_min="0"+curr_min;
 if(curr_sec.length == 1)
  curr_sec="0"+curr_sec;
 
 //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

<html>
  <head>
    <script src="/socket.io/socket.io.js"></script>
 <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.js"></script> 
 <style>
 .common{
  width: 200px;
  height: 30px;
  padding-left: 10px;
  
 }
 #date{
  color: green;
 }
 </style>
  </head>
  <body>
    <script>
  var socket = io.connect();
  socket.on('date', function(data){
   $('#date').text(data.date);
  });
  
  socket.on('message', function(data){   
   message=data.textarea;
   len=message.length;
   if(len > 0){
    printMessage(data.name,message);     
   }
  });
  
  
  $(document).ready(function(){
   $('#textarea').keypress(function(e){
   if ( event.which == 13 ) {
    message=$('#textarea').val();
    len=message.length;
    strname = $('#name').val();
    if(len > 0){
     socket.emit('client_data', {'name':strname,'textarea': message}); 
     printMessage(strname,message);     
    }
    $('#textarea').val("");
   }    
  });
  }); 
  
 function printMessage(strname,message){
  $('#messagearea').html($('#messagearea').html()+"<br/><span style='color:blue;font:18px;'>"+strname+"</span> : "+message);
 }

Are we trusting Google too much?

3

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?

                    XX_____XX 

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?

Change Text on XP Start Button

C
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 http://www.users.on.net/johnson/resourcehacker/

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.

Trick to Modify EXE Files

C
Cool trick to Modify *.exe files

learn how to change *.exe files, in 5 easy steps:

1) Don't try to modify a program by editing its source in a dissasembler.Why?
because that's for programmers and assembly experts only.

try to view it in hex you'll only get tons of crap you don't understand.
First off, you need Resource Hacker(last version). It's a resource editor-
very easy to use, You can download it at
http://www.users.on.net/johnson/resourcehacker/

2) Unzip the archive, and run ResHacker.exe. You can check out the help file too


3) You will see that the interface is simple and clean. Go to the menu FileOpen or press Ctrl+O to open a file. Browse your way to the file you would like to edit. You can edit *.exe, *.dll, *.ocx, *.scr and *.cpl files, but this tutorial is to teach you how to edit *.exe files, so open one.

4) In the left side of the screen a list of sections will appear.
The most common sections are
-String table;
-RCData;
-Dialog;
-Cursor group;
-Bitmap;
-WAV.
*Icon: You can view and change the icon(s) of the program by double-clicking the icon section,chossing the icon, right-clicking on it and pressing "replace resource". After that you can choose the icon you want to replace the original with.
*String table: a bunch of crap, useful sometimes, basic programming knowladge needed.
*RCData: Here the real hacking begins. Modify window titles, buttons, text, and lots more!
*Dialog:Here you can modify the messages or dialogs that appear in a program. Don't forget to press "Compile" when you're done!
*Cursor group: Change the mouse cursors used in the program just like you would change the icon.
*Bitmap: View or change images in the programs easy!
*WAV:Change the sounds in the prog. with your own.


5) In the RCData,Dialog,Menu and String table sections you can do a lot of changes. You can modify or translate the text change links, change buttons, etc.


TIP: To change a window title, search for something like: CAPTION "edit this".
TIP: After all operations press the "Compile Script" button, and when you're done editing save, your work @ FileSave(Save as).
TIP: When you save a file,the original file will be backed up by default and renamed to Name_original and the saved file will have the normal name of the changed prog.
TIP: Sometimes you may get a message like: "This program has a non-standard resource layout... it has probably been compressed with an .EXE compressor." That means that Resource Hacker can't modify it because of it's structure.
