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>
  </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){

1. Set up the Android Workspace

https://developer.android.com/training/basics/firstapp/index.html

2. Create your Hello World Android application
https://developer.android.com/training/basics/firstapp/creating-project.html

Lets start the game development.

Just follow this Four Steps to start your first simple android game.

Step 1: Create a Game Loop Thread that renders the Frames.

Step 2: Create a SurfaceView class that will show the game UI and controls the game.

Step 3: Create a Image handler class that will help you in collision detection and loading bitmap images.

Step 4: Wire up your MainActivity.

Post your comments in case of any difficulty and help.

Step 1: Create a Game Loop Thread that renders the Frames.
MainThread.java.

package com.coolcomputerpctricks.tutorialgame;

import android.graphics.Canvas;
import android.util.Log;
import android.view.SurfaceHolder;

/** 
 *  www.coolcomputerpctricks.com
 *  Android Game development tutorial * 
 */

public class MainThread extends Thread {
 
 private static final String TAG = MainThread.class.getSimpleName();
 
 // Frames Per seconds
 public  int MAX_FPS = 150; 
 private  int FRAME_PERIOD = 1000 / MAX_FPS; 
 private SurfaceHolder surfaceHolder;
 private ViewGamePlay gamePanel;
 private boolean running;
 
 public void setRunning(boolean running) {
  this.running = running;
 }

 public MainThread(SurfaceHolder surfaceHolder, ViewGamePlay gamePanel) {
  super();
  this.surfaceHolder = surfaceHolder;
  this.gamePanel = gamePanel;
 }

 @Override
 public void run() {
  Canvas canvas;
  long beginTime;  
  long timeDiff;  
  int sleepTime;  
  sleepTime = 0;
  while (running) {   
   canvas = null;
   try {
    canvas = this.surfaceHolder.lockCanvas();
    synchronized (surfaceHolder) {
     beginTime = System.currentTimeMillis();
     this.gamePanel.render(canvas);    
     timeDiff = System.currentTimeMillis() - beginTime;
     sleepTime = (int)(FRAME_PERIOD - timeDiff);
     if (sleepTime > 0) { 
      try {
       Thread.sleep(sleepTime); 
      } catch (InterruptedException e) {}
     }
     
    }
   } finally {
    if (canvas != null) {
     surfaceHolder.unlockCanvasAndPost(canvas);
    }
   } 
  }
 } 
}

Step 2: Create a SurfaceView class that will show the game UI and controls the game.
ViewGamePlay.java

package com.coolcomputerpctricks.tutorialgame;

import java.util.Random;

import android.content.Context;
import android.graphics.BitmapFactory;
import android.graphics.Canvas;
import android.view.MotionEvent;
import android.view.SurfaceHolder;
import android.view.SurfaceView;
/** 
 *  www.coolcomputerpctricks.com
 *  Android Game development tutorial * 
 */

public class ViewGamePlay extends SurfaceView{

 
 MainThread thread;
 ItemImages bgImage,parachute;
 int max,min;
 
 public ViewGamePlay(Context context) {
  super(context);
  thread = new MainThread(getHolder(), this);
  getHolder().addCallback(new SurfaceHolder.Callback() {
   public void surfaceDestroyed(SurfaceHolder holder) {
    boolean retry = true;
    while (retry) {
     try {
      thread.setRunning(false);
      thread.join();
      retry = false;
     } catch (Exception e) {
      e.printStackTrace();      
     }
    }
   }
   public void surfaceCreated(SurfaceHolder holder) {
           
     Canvas c = holder.lockCanvas(null);
     initializeGame(c);
     drawGame(c);
     holder.unlockCanvasAndPost(c); 
     thread.setRunning(true);
     try{
      thread.start();
     }catch(Exception e){
      e.printStackTrace();
     }
   }

   public void surfaceChanged(SurfaceHolder holder, int format, int width, int height) {
    //Surface changed
   }
  });  

 }



 public void initializeGame(Canvas canvas){
  
  bgImage =  new  ItemImages(BitmapFactory.decodeResource(getResources(), R.drawable.sky),0,0);
  parachute = new  ItemImages(BitmapFactory.decodeResource(getResources(), R.drawable.parachute),0,0);
  
  //Random left position for the parachute
  max=(int) (canvas.getWidth()-parachute.getWidth());
  min=0;
  Random rand = new Random();  
  int randomNum = rand.nextInt((max - min) + 1) + min;
  parachute.setLeft(randomNum);
 
 }
 
 protected void drawGame(Canvas canvas) { 
  
  bgImage.drawBMP(canvas);
  parachute.drawBMP(canvas);
   
 } 
 
 
 public boolean onTouchEvent(MotionEvent event) {
  float x = event.getX();
  float y = event.getY();
  if(parachute.isCollition(x, y))
   {
    // If player touched, reset the parachute location
    parachute.setTop(0);
    Random rand = new Random();  
    int randomNum = rand.nextInt((max - min) + 1) + min;
    parachute.setLeft(randomNum);
    
   }
  return true;
 }
 
 public void render(Canvas canvas) {
  
  parachute.setTop(parachute.getTop()+2);
  
  if(parachute.getTop()>canvas.getHeight()){
   parachute.setTop(0);
   // Reset the parachute location
   parachute.setTop(0);
   Random rand = new Random();  
   int randomNum = rand.nextInt((max - min) + 1) + min;
   parachute.setLeft(randomNum);
  }  
  drawGame(canvas);
 }
 
 
}

Step 3: Create a Image handler class that will help you in collision detection and loading bitmap images.
ItemImages.java

package com.coolcomputerpctricks.tutorialgame;

import android.graphics.Bitmap;
import android.graphics.Canvas;
import android.graphics.Matrix;
import android.graphics.Rect;


/** 
 *  www.coolcomputerpctricks.com
 *  Android Game development tutorial * 
 */

public class ItemImages {
 private float width;
    private float height;
    private float left;
    private float top;
    private Bitmap bmp;
    private boolean visible; 
    
    public ItemImages(Bitmap bmp,float left, float top)
    {
     this.width = bmp.getWidth();  
        this.height = bmp.getHeight();
        this.bmp=bmp;
  this.left=left;
  this.top=top;
  this.setVisible(true);
    }
    public void setBmp(Bitmap bmp) {
  this.bmp = bmp;
 }
 public void drawBMP(Canvas canvas) {
  if(canvas!=null && bmp!=null)
   canvas.drawBitmap(bmp, left, top, null);
    }
    public void drawBMP(Canvas canvas,Rect src,Rect dst) {
  if(canvas!=null && bmp!=null)
   canvas.drawBitmap(bmp, src, dst, null);
    }
    public boolean isCollition(float x2, float y2) {
        return x2 > left && x2 < left + width && y2 > top && y2 < top + height;
    }
 public float getWidth() {
  return width;
 }
 public void setWidth(float width) {
  this.width = width;
 }
 public float getHeight() {
  return height;
 }
 public void setHeight(float height) {
  this.height = height;
 }
 public float getTop() {
  return top;
 }
 public void setTop(float top) {
  this.top = top;
 }
 public float getLeft() {
  return left;
 }
 public void setLeft(float left) {
  this.left = left;
 }
 public boolean isVisible() {
  return visible;
 }
 public void setVisible(boolean visible) {
  this.visible = visible;
 } 
}

Step 4: Wire up your MainActivity.
MainActivity.java

package com.coolcomputerpctricks.tutorialgame;

import android.app.Activity;
import android.os.Bundle;
import android.view.Menu;
/** 
 *  www.coolcomputerpctricks.com
 *  Android Game development tutorial * 
 */

public class MainActivity extends Activity {

 @Override
 protected void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  
  setContentView( new ViewGamePlay(this)); 
 }


}

Are we trusting Google too much?

noreply@blogger.com (karthi) — Sat, 15 Jun 2013 17:41:00 +0000

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?

Google's New Scientific Calculator

noreply@blogger.com (karthi) — Sat, 28 Jul 2012 08:27:00 +0000

Google Restricts Labels in blogger (robot.txt)

noreply@blogger.com (karthi) — Mon, 27 Feb 2012 17:44:00 +0000

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 coolcomputricks.co.cc, the url pointing to that label is this

http://www.coolcomputricks.co.cc/search/label/Windows%20Trick

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.

Renaming Multiple Files

noreply@blogger.com (karthi) — Tue, 31 Jan 2012 10:55:00 +0000

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

Google can do Calculators job toooo!!!

noreply@blogger.com (karthi) — Thu, 01 Jul 2010 15:33:00 +0000

Using the Google calculator:

Google’s calculator tries to understand the problem you are attempting to solve without requiring you to use special syntax. However, it may be helpful to know the most direct way to pose a question to get the best results. Listed below are a few suggestions for the most common type of expressions (and a few more esoteric ones).

Most operators come between the two numbers they combine, such as the plus sign in the expression 1+1.

Operator

Function

Example

+

addition

3+44

-

subtraction

13-5

*

Multiplication

7*8

/

Division

12/3

^

exponentiation(raise to a power of)

8^2

%

modulo(finds the remainder after division)

8%7

X choose Y

determines the number of ways of choosing a set of Y elements from a set of X elements

18 choose 4

nth root of x

calculates the nth root of a x

5th root of 32

X % of Y

computes X percent of Y

20% of 150

Some operators work on only one number and should come before that number. In these cases, it often helps to put the number in parentheses.

Operator

Function

Example

sqrt

square root

sqrt(9)

sin, cos, etc.

trigonometric functions (numbers are assumed to be radians)

sin(pi/3)

tan(45 degrees)

ln logarithm base e ln(17)

log logarithm base 10 log(1,000)

A few operators come after the number.

!

factorial

5!

Other good things to know

Parentheses can be used to enclose the parts of your expression that you want evaluated first. For example, (1+2)*3 causes the addition to happen before the multiplication.

The in operator is used to specify what units you want used to express the answer. Put the word in followed by the name of a unit at the end of your expression. This works well for unit conversions such as: 5 kilometers in miles.

You can use hexadecimal, octal and binary numbers. Prefix hexadecimal numbers with 0x, octal numbers with 0o and binary numbers with 0b. For example: 0x7f + 0b10010101.

The calculator understands many different units, as well as many physical and mathematical constants. These can be used in your expression. Many of these constants and units have both long and short names. You can use either name in most cases. For example, km and kilometer both work, as do c and the speed of light.

Feel free to experiment with the calculator as not all of its capabilities are listed here. To get you started, we’ve included a few expressions linked to their results.

1 a.u./c

56*78

1.21 GW / 88 mph

e^(i pi)+1

100 miles in kilometers

sine(30 degrees)

G*(6e24 kg)/(4000 miles)^2

0x7d3 in roman numerals

0b1100101*0b1001
