Getting started with HTML5 canvas

2012-07-25T03:55:00.002-07:00

HTML5 canvas element is a simple HTML tag. It allows dynamic and script-able rendering of 2D and bitmap images. Canvas consists of a drawable region defined in HTML code with height and width attributes. Javascript code is used to access the area through a full set of drawing functions.
In this tutorial I'm going to explain the basics of canvas element and how it can be used to draw a line. So in order to use the canvas element , you'll need to place the canvas element somewhere inside your html.

<!DOCTYPE HTML>
<html>
  <head>
    <script>
      window.onload = function() {
        var canvas = document.getElementById("canvas_area");
        var context = canvas.getContext("2d");
             //code here 
     
      };

    </script>
  </head>
  <body>
    <canvas id="canvas_area" width="600" height="300"></canvas>
  </body>
</html>

The code above will be the base template for all of your future HTML5 Canvas projects. We can define the height and width of the canvas tag using the height and width attributes, just like we would with any other HTML tag. Inside the initializer function we can access the canvas DOM object, and then get a 2-d context using the getContext() method.

How to draw a line

<!DOCTYPE HTML>
<html>
  <head>
   <style>
    #canvas_area{
    border:solid 1px #999;
    }
   </style>
    <script>
      window.onload = function() {
        var canvas = document.getElementById("canvas_area");
        var context = canvas.getContext("2d");
        context.beginPath();
        context.moveTo(100,150);
        context.lineTo(400,250);
        context.stroke();
      };

    </script>
  </head>
  <body>
    <canvas id="canvas_area" width="600" height="300"></canvas>
  </body>
</html>

A little explanation

beginPath() - defines a new drawing path.
moveTo() - creates a new subpath for the given point. This point becomes the new context point. You can think of the moveTo() method as a way to position your drawing cursor.
lineTo() - draws a line from the context point to the given point.
stroke() - assigns a color to the line and makes it visible. Unless otherwise specified, the default stroke color is black.

How to hack Facebook / Twitter accounts using firesheep ?

2011-08-08T16:55:00.000-07:00

Hacking Facebook/Twitter accounts using Firesheep is one of the easiest methods. The only thing that you need is that the victim should be in the same network that you are in. Firefox has an add-on called Firesheep designed to show the security holes in sites that don't use encryption for all their traffic, works as advertised. All you want to do is download and install Firesheep first. Then open the Firesheep sidebar and click "Start Capturing." Now you can see the a list of users logged into the Facebook, I double-clicked on it. But the thing is you cant change the password without knowing his/her old password, but you can read their private messages, you have access to his/her personal data, photos and all.

Firesheep uses a packet sniffer to intercept unencrypted cookies from certain websites (such as Facebook and Twitter) as the cookies are transmitted over networks, exploiting session hijacking vulnerabilities.

Worlds first website was published 20 yeas ago!

2011-08-08T15:49:00.000-07:00

1991 August 6 , at a CERN facility in the Swiss Alps, when 36-year-old physicist Tim Berners-Lee published the first-ever website. It was, not surprisingly, a pretty basic one — according to CERN:

info.cern.ch was the address of the world’s first-ever web site and web server, running on a NeXT computer at CERN. The first web page address was http://info.cern.ch/hypertext . Visitors could learn more about hypertext, technical details for creating their own webpage, and even an explanation on how to search the Web for information. There are no screenshots of this original page and, in any case, changes were made daily to the information available on the page as the WWW project developed. You may find a later copy (1992) on the World Wide Web Consortium website.

Of course, the only people who actually had web browser software were Berners-Lee and his colleagues at CERN, so the world at large remained almost entirely ignorant of the momentous event that had just taken place. Gradually installations of web servers and the use of web browsers spread, but it really wasn’t until 1993, when the Mosaic browser was released, that the technology really achieved serious momentum.

In 1994, Berners-Lee founded the World Wide Web Consortium (often referred to as “W3C”) at MIT in order to create standards for the web to ensure that different websites would all work the same way. Berners-Lee, now 56, is still the director of the W3C, in addition to several other positions he holds. While there are and surely always will be some deviations from the standards by many websites and browsers, it’s not a stretch to say that the web as we know it would probably not exist if not for the W3C’s guidance.

It can be hard now, even for many of us who regularly used the Internet before there was a World Wide Web, to remember that there was a time when the two terms weren’t considered nearly synonymous by the general public. Of course, that’s partly because, before the proliferation of websites that followed Mosaic’s release (and for some time thereafter), most members of the general public didn’t have the least idea that the Internet even existed.

And it’s nigh-impossible to conceive of just how different the world would be today were it not for the event of twenty years ago today. Heck, you’d probably have to go to comp.wired.geekdad on Usenet to read this blog.

Facebook Introducing Topic Groups !!!

2011-08-08T15:44:00.000-07:00

Part of Facebook’s 'awesome announcement' recently was the addition of Skype-powered video chat, adding face-to-face calling. As part of this update, facebook also changed its chat layout, bringing a new sidebar to all pages. The thing is, this new addition to an already crowded Facebook layout, isn’t entirely to everyone’s tastes. It’s large, it’s clunky, and it’s largely unnecessary. But nowadays Facebook has started grouping the status updates by topic, in the hopes that the update will help make sense of your News Feed. Its realaly good. Now, should your friends be sharing posts with similar themes — such as going to see the same movie — you’ll see a single News Feed story that lumps them together. “You may notice some of your news feed stories are now grouped together by topic,” the 750 million member-strong social network posted on its Facebook Page Monday. “We want to show you the most relevant and interesting information, and this test is designed to show you trends among what your friends are saying.”As with every Facebook change, not all users are loving the algorithmic alteration. Many of the initial comments on Facebook’s post were negative.

How to find if your friend is invisible or offline in gtalk.

2011-08-07T18:35:00.000-07:00

Using this trick you can easily find whether the user is invisible or offline in gtalk / gmail.

Using gtalk

Open the chat window of the victim that you want to check.

There is a down arrow icon on the right top of the window, click the icon and select "Go off the record".

Then send some text ( example : "hellloooooooooo" )

If the user is offline google will give you a message like " someuser@gmail.com is offline and can't receive messages right now." otherwise if he/she is invisible there will not be any response.

Using gmail

If you are using gmail's chat you can't select the option when he/she is offline/ invisible, so whenever you see him online, just set the chat as off the record with him from the arrow icon on the top right part of the window and follow the same procedure as explained above in the case of gtalk.

Program to resume all your transmission torrent downloads when your computer is idle and pauses when it's active!

2011-06-16T06:37:00.000-07:00

Hai, Recently I changed my broadband plan to unlimited. The new plan is much slower than the old one and I can't browse pages smoothly when my torrents are active. So I have to pause all downloads when I'm using my computer and resume before I go somewhere. The problem is, most of the times I forgot to do this; At last I decided to write a program to automate it :)

You must enable your screensaver before running this program and turn on the web client of transmission torrent [ edit > preferences > web ]

# This program automatically resumes your transmission torrent downloads 
# when your computer is idle and pause when its active. 
# ( you must enable your screensaver and turn on webclient of transmission torrent ) 
# [ Author : Sreekumar ]

import gobject
import dbus
import os
from dbus.mainloop.glib import DBusGMainLoop

DBusGMainLoop(set_as_default = True)
session_bus = dbus.SessionBus()

def stateChanged(state):
    #state : represents wheather the screensaver is avtive or not
    if state == 1:
        print "Resuming Downloads..."
        #resumes all transmissions 
        os.system("transmission-remote --torrent all --start")
    else:
        print "Downloads Paused!"
        #pause all transmisssions
        os.system("transmission-remote --torrent all --stop") 

session_bus.add_signal_receiver(stateChanged,"ActiveChanged","org.gnome.ScreenSaver")

#this is to check for new events from each of the event sources and dispatch them
mainloop = gobject.MainLoop()
mainloop.run()

How to configure Sony Vaio CW + Nvidia Drivers in ubuntu !

2011-06-10T11:13:00.000-07:00

Installing ubuntu in sony vaio cw series and configuring with nvidia display driver is a little complicated stuff . Here is a solution for that.

First you insert your disk and press f6 from boot menu and select "nomodeset" and boot.

( screenshot is taken using virtualbox because i cant take it from the original boot menu)

further installation steps are as usual

after installing remove the cd / other installation media and reboot the system.

again you will get a menu like i added below

press e ( to edit)

now you have to add the option nomodeset

type nomodeset just after quit splash and press ctrl + x to boot

download these files

nvidia driver - display driver

http://www.nvidia.in/object/linux_display_ia32_190.42.html

edid.bin - Extended display identification data

http://www.4shared.com/file/cNpBak4w/edid.html

Xorg.conf - xorg configuration
http://www.4shared.com/file/RF1eFNIU/xorg.html

now you have

1. NVIDIA-Linux-x86-190.42-pkg1.run

2. xorg.conf

3 . edid.bin

place all these files in your home folder.

ok, again reboot your system and choose the second option recovery mode

after that you will get something like this. choose netroot from that menu

then you will get a root shell

type

> init 3

and press enter . This is to change the run level to 3. now you will get text-mode login. use your username and password to login after that run these commands

 
> sudo chmod +x ./NVIDIA-Linux-x86-190.42-pkg1.run

> sudo ./NVIDIA-Linux-x86-190.42-pkg1.run

> sudo cp xorg.conf /etc/X11/xorg.conf

> sudo cp edid.bin /etc/X11/edid.bin

> sudo reboot

the last command reboots your system and still you have problems boot to the recovery mode again as i mentioned above and choose the netroot option and edit the file /boot/grub/grub.cfg

 
> sudo nano /boot/grub/grub.conf

and find the line that we modified earlier to add nomodeset option ( remember that option will not be there now) so we have to add it after "quit splash" . and save the file by pressing ctrl + o and press enter and ctrl + x to exit. then reboot

> sudo reboot

Everything will be alright now :)

How to know what's being copied from your blog / website !

2011-06-10T08:19:00.000-07:00

Program to count the number of lines of code in your project !

2011-06-09T16:06:00.000-07:00

This is a simple program in python which counts the total number of lines of code in a list of files from a directory.

 #Program to count the number of lines of code in project
#Author : Sreekumar
#
import sys
import fnmatch
import os
rootPath = sys.argv[1]
pattern = sys.argv[2]
total_lines = 0
lines =  0
for root, dirs, files in os.walk(rootPath):
    for filename in fnmatch.filter(files, pattern):
            filename =  os.path.join(root, filename)
           try:
            f = open(filename,"r")
             lines = len(f.readlines())
            print filename + " : %d Lines"% lines
        total_lines += lines
        except IOError:
        print "Some error"
print "\nTOTAL LINES : %s "% total_lines

Save this program as "yourfilename.py" and open a terminal
type

python yourfilename.py /yourprojectdir-path/ *.*

example :

python countlines.py "/home/x/mypro/" "*.php"

the last argumet *.php" specifies the pattern to be filtered from the list of files.

Best download manager for Linux ! ( Like IDM )

2011-06-06T12:27:00.000-07:00

I was in search of a download manager like IDM in Linux and I search a lot on blogs and forums, but i never get any solution. I have tried many but I never find any download managers in Linux like Internet download manager. At last I found one.. "Multiget". MultiGet is an easy-to-use GUI file downloader for Windows/Linux/BSDs/MacOs. It's programmed in C++ and has a GUI based on wxWidgets. It supports HTTP/FTP protocols which covers the requirements of most users. It supports multi-task with multi-thread on multi-server. It supports resuming downloads if the Web server supports it, and if you like, you can reconfig the thread number without stopping the current task. It's also support SOCKS 4,4a,5 proxy, ftp proxy, http proxy.

n v0.8.0, a new feature was introduced, that is so called P2SP, or in other words , get file from multiple servers, and combine the data from different site into one file. This makes downloads complete much faster.

MultiGet also supports switching language dynamically, you can choose Chinese or English interface. Generally it will automatic choose a proper language for you.

At this time(version 1.1.1), MultiGet can run on Windows 2000/XP, almost all Linux desktops, MacOs, BSDs. It can only depends on GTK+ runtime environment in Linux if statically linked with wxWidgets. It was tested on many system such as : Windows 2000, ubuntu ,kubuntu, xubuntu, fc5, opensuse10.4, mandriva 2007, MEPIS 6.0, PCLinuxOS, CentOS4.4, Puppy2.0, Xandros, edubuntu, RedFlag workstation 5, MagicLinux, dubuntu, archlinux, Hiweed, FreeBSD, MacOS etc.

To install multiget:

open a terminal and type

sudo apt-get install multiget

Actually i tried ubuntu about five years ago and that time i was not aware of using it properly but i liked it only because its different from Windows. But now i realize its power !!! one of the main reason why i use ubuntu because it allows me to be in full control over my computer. Actually

Program your symbian phone from your computer using Python!

2010-10-24T05:10:00.000-07:00

Since python is gaining more and more interest among symbian developers and more and more applications are written in Python. So its almost a necessity to have python in your mobile. As i mentioned in my previous post PyS60 support programming your symbian s60 phones.

But i know its hard to write programs from your phones. PyS60 have an option called Bluetooth console which is an interactive python interpreter running on your phone that communicates with your computer over a bluetooth connection.

Here i will describe, How to setup PyS60 bluetooth console and Linux!

You will need at least the following tools:

hcitool to scan your mobile device

sdptool and sdpd daemon to register services like serial port

rfcomm to emulate serial port over bluetooth

minicom a serial communication program

Then follow these instructions

I hope you have blutooth adapter connected to your computer else plug-in your bluetooth adapter

Then from the terminal type:

$hciconfig reset

Then check that the device is there

$hcitool dev

Then next step is to register a serial port(use channel 1, that may vary)

$sdptool add --channel=1 SP

Now start listing to the the channel

$rfcomm listen rfcomm1 1

Ok, now pickup your phone and make sure that bluetooth is on then go to your python application and select the bluetooth console. Select your host from the list.

Now it will establish a connection between your phone and computer.

Next you open a new terminal and write the following command

$minicom -o -D /dev/rfcomm1

Now you are in your phones python console.... Enjoy !
