How to Enable Transaction Rights in Online SBI

I recently applied for online banking at SBI ( State Bank of India ). I became very exited when I received the login details (username and password) for my SBI online banking. I rushed to the computer and opened onlinesbi.com and tried to purchase something from amazon. But, when I selected to pay via online banking and logged in into my SBI online account it said something like "Your account does not have transaction rights". My face turned from :D to :(

LibGDX HTML Game Keyboard Controls Problem Solved

Yesterday, I have made a game using libGDX and published the html game to itch.io and gamejolt.com
Here is the game http://ravicake.itch.io/pong-simple

After that I've published the game, I try to play the game in the web browser. But I noticed that keyboard controls are not working. The game was working fine when testing.

I tried to view the game without iframe ( web games on gamejolt and itch.io are embedded in iframe ) by right clicking on the game frame and then -> show only this frame (in firefox). Voila! the keyboard controls are working fine again.

From that, it is clear that there are some problems which does not let keyboard controls to work in iframe.

I searched the internet but I could not find any solution. But after searching for some more time I got something.
I found a solution, not perfect but working. Here is it:

In libGDX's html game's index.html add the following line in the handleMouseDown() function

window.focus();

Now the keyboard controls are working as it should.

11 millions Ashley Madison Passwords Cracked in 10 days

Last month, hackers leaked nearly 100 gigabytes of sensitive data of the popular marriage affair website 'Ashley Madison'. But one thing was in favor of 36 million users that their passwords were encypted by bcrypt, an algorithm so slow that it would literally take years to crack them.

But a group of crackers, CynoSure Prime, has found a weak spot. They found that some of the login tokens were protected using MD5. This made the password cracking process about a million times faster.

The password cracking group, CynoSure Prime, has cracked more than 11 million user passwords in just 10 days.

The password cracking group CynoSure, brute-forced the MD5 login tokens instead of slow Bcrypt, which allowed them to obtain nearly 11 million passwords in plaintext format.

However, this approach doesn't allow them to crack all 36 million passwords. Because all the passwords were not encypted with MD5 algorithm.

Researchers estimated that nearly 15 million Ashley Madison password could be affected, out of which 11+ millions passwords are already cracked.

Making Firefox Add-Ons Using CFX Tool

Making Firefox add-ons is easy. One only have to know HTML, CSS, and JavaScript to develop firefox addons/extensions.

I am going to use the cfx tool for creating firefox add-ons. You can download the Add-on SDK 1.17 directly in either zip format or tarball format.

Note: cfx has been deprecated,jpm should now be used instead. We'll cover jpm on some later posts.



cfx enables us to test, run and package add-ons.

cfx usage:

cfx [options] command [command-specific options]

We only need to know three cfx commands right now to make our first firefox add-on. These are:

• cfx init
• cfx run
• cfx xpi

cfx init is used to initialise the files and folders for our add-on. cfx run is used to run the add-on in firefox while all other add-ons are disabled. And cfx xpi is used to package the add-on into an xpi.

Now let's start making our first firefox add-on.

STEP 1

First download the Add-on SDK from the link above and then extract the file.

STEP 2

Open command prompt (if you're on windows) or terminal (if you're on linux) and navigate to the bin directory located in the extracted folder. And then type activate to activate the add-on sdk.

STEP 3

Now make a directory/folder and name it anything you want (this will be used to store the files of the add-on). And then navigate to the newly created directory/folder. And type cfx initThis will create all the necessary files and folders for our add-on. The directory structure will look like this:

my-addon   

• data
  
• docs        
  • main.md
     
• lib        
  • main.js
     
• package.json
  
• README.md
  
• tests        
  • test-main.js
     

STEP 4

Open the main.js file located in the lib directory. And edit the content of the file to the following:

var { ToggleButton } = require("sdk/ui/button/toggle");

var button = ToggleButton({
    id: "test_button",
    label: "Facebook Mobile",
    icon: {
        "16": "./icon-16.png",
        "32": "./icon-32.png",
        "64": "./icon-64.png"
    },
    onChange: clickFunction
});

function clickFunction(state){
    if(state.checked){
        panel.show({
            position: button
        });
        
    }
}

var panels = require("sdk/panel");

var panel = panels.Panel({
    width: 500,
    height: 600,
    contentURL: "https://m.facebook.com",
    onHide: handleHide
});

function handleHide(){
    button.state("window" , {
        checked: false
    });
}

This will make a toggle button and upon clicking on it it will show a website (here http://m.facebook.com) inside the panel. This is my first firefox add-on, you can find it at addons.mozilla.org

STEP 5

After writing the code and everything now it's time to export our firefox add-on. To do this we type cfx xpi in the command prompt/terminal.
You can find my completed addon here at addons.mozilla.org and also find my other addons here.
That's it for more info on developing firefox add-ons read the official documentation.

Compiling and Running C++ Program using GNU C/C++ Compiler

I'm using Ubuntu and GNU C/C++ compiler to compile and run c++ programs. So this how we compile c++ program in Linux.

https://gcc.gnu.org/

Compiling C++ program using GNU C/C++ comiler

Let's create a file called helloworld.cpp using a text editor such as vi or emacs and write your program (I made a simple hello world program here).

#include 

int main()
{
  std::cout << "Hello, World!" << std::endl;
  
  return 0;
}

Compiling this program using GNU C/C++ comiler

(Assuming we are in the same directory as the cpp source file) Syntax for compiling:

g++ name_of_source_file.cpp -o name_of_output_file

Assuming the name of the file is helloworld.cpp, in the terminal we write:

g++ helloworld.cpp -o helloworld

Note: To show warnings and errors while compiling, we use -Wall option.

g++ -Wall helloworld.cpp -o helloworld

This will create an executable file called helloworld and to run/execute this file follow the steps below.

Running/Executing C++ program

(Assuming we are in the same directory as the executable) Syntax for executing:

./name_of_executable_file

In our case the executable file name is "helloworld", therefore we write:

./helloworld

That's it!
Happy Programming :)

Learning C++

After learning the basics of JavaScript I am thinking of learning C++. So I'll start learning C++ as soon as I can. And also, C++ is in my course book so It will be a fun and good learning experience.

C++ was developed by Bjarne Stroustrup of AT&T Bell Laboratories in the early 1980's, and is based on the C language. C++ runs on a variety of platforms, such as Windows, Mac OS, and the various versions of UNIX. Also it is very fast.

My first step will be to choose some books on C++ and start learning from them.
I'll be updating my progress through blog posts and twitter. So stayed tuned and Happy Programming :D

Learning JavaScript : Basics

Few days ago I decided to learn JavaScript. And started learning the basics of the language.
Here is what I have learned so far:

Variables:

There are six data types in JavaScript: number, string, Boolean, null, undefined and object.

Declaring a variable is simple.

var myVariable;

We can also initialize it as:

var  myVariable = "This is a string variable.";

Functions:

Function is used to group a set of operations. And call it whenever we want to use it.
A function can be defined as:

function helloWorld(){
  alert("Hello, World!");
}

To call this function we do:

helloWorld();

Events:

Click events
Click events are the mouse click events.
Let's try to do something when we click a button.
We will show an alert box when we press/click the button.



Here is the javascript code for this button:

  <input type="button" value="Click Me!" onclick="alert('You clicked me!')">
  

This is only the basics of JavaScript which I've learnt. Next time I will show more about JavaScript. Till then, check out my other posts and follow me on twitter: @RaviiKmr to get my updates.

How to Get Started Blogging

I am a terrible writer. You can see that in blog. However, this is not a reason to stop writing. I always wanted to start a blog and write about stuffs that interests me. So, I started this blog a while ago. At That time I had no idea what should I do and write about in this blog. I was just procrastinating about stuffs, switching from topic to topic. But could not stabilize my thoughts about what to write.

Recently, I found a free email course about "How to create a blog" by John Sonmez, the founder of Simple Programmer. He is a software developer, author, speaker, entrepreneur, podcaster, blogger, consultant and more. He is also a life coach for the software developers. He helps software developers, programmers and other technical professionals boost their careers. In his email course, he has simplified the steps to create a good blog and also convinced people like me to start a blog.

This email course has given me confidence and a reason to write. It also given me a timely schedule to stick with. And kick-started me to write this blog.
I am very thankful to John Sonmez for providing this email course.

You can sign up for John Sonmez's email course here: http://devcareerboost.com/blog-course/

Python Charming

With plenty of peace and prosperity Wishing a very Happy Saraswati Puja (basant panchami) to my Indian friends ( and "not friends" too :p ).

Ah!, What a day it was! lots of fun and happiness. Finally got tired.
Now I feel bored so I decided to do something new tonight. I thought of doing many new things but decided to do snake charming. Yes, Snake Charming. That's why I brought a python tonight.

Now I can try to charm this python with my keyboard in my computer. Actually I tried python before but it got away that time. I hope I can learn it this time.
