Hacking android app (Basic)

Search and download the apk file, you can use following links to search your apk if you don't have one


convert extension of the file from .apk to .zip and extract this zip, now you get the resources and other files, to get the classes decompile the file classes.dex to jar with an app from this link http://code.google.com/p/dex2jar/downloads/list

Step 1 extract the contents of dex2jar.*.*.zip file
Step 2 copy your .dex file to the extracted directory
Step 3 execute dex2jar.bat <.dex filename> on windows, or ./dex2jar.sh <.dex filename> on linux

then you can use jd-gui, the source code is quite readable as dex2jar makes some optimizations.

Create/Deploy Android project by comand line

Creating and deploying a new Android project by Mac terminal is an exciting experience for me, for this all what i needed are Ant, Mac Terminal and Android SDK only :)

Installing or Upgrading Ant in Mac OSX

First of all Ant already come with Mac OSX, but if you really need to install it or want to upgrade it, though, the best way would be to install it through MacPorts (using sudo port install apache-ant). To install it manually you can follow these simple steps:

Installing and Configuring MacPorts

Prepopulate SQLite DataBase in PhoneGap Application

This is an old post, please refer:
https://github.com/brodysoft/Cordova-SQLitePlugin - a Cordova/PhoneGap plugin to open and use sqlite databases on Android/iOS/WP(8) with HTML5 Web SQL API

It is really hard to wait for too much time when a phonegap application runs for first time and create all its database stuff, which gives a really bad impression to the user who just downloaded the app for its iPhone or Android device. I have a little approach to save the long time taken for database creation at very first run of the app, that is; we should copy a Pre-Populated Database file to the native location of device.

Sprite3D or 3D HTML5

I think we can say 3D-HTML ;) because Sprite3D wraps HTML elements with the necessary behaviors to easily control their 3D-position using a simple JavaScript syntax.

WebSocket in HTML5

HTML5 provides a new thing called a WebSocket. Now data can flow between the browser and server without having to send HTTP headers until the connection is broken down again. Welcome to the world of PUSH technology!

What is Websocket?
WebSocket is bi-directional (full-duplex) communication channel over a single TCP (Transmission Control Protocol) socket for client or server application... goes too much technical, ok then
WebSockets opens a connection to a server and the connection stays open until you decide to close it. From there, you can start sending messages from the browser to the server and you can define a callback function for when the server send data back. Basically we got rid of each time new request for server.

It is a truly better and easier way for syntax highlighting of code snippets in a web page with good cross-browser support. It contains a Theme based Customizable CSS file which you can chose from its gallery of theme and a Javascript module file that allows syntax highlighting of source code snippets in an html page. It is also light weighted and have basic support to all  C (and friends), Java, Python, Bash, SQL, HTML, XML, CSS, Javascript, and Makefiles languages (because of commenting conventions, doesn't work on Smalltalk, or CAML-like languages), and we don't need to specify the language. Apart this for Clojure, CSS, Go, Haskell, Lua, OCAML, SML, F#, Nemerle, Protocol Buffers, Scala, SQL, TeX, LaTeX, VHDL, Visual Basic, WikiText, XQuery, and YAML. it have an extensible language handlers for other languages in such case you can specify the language.

Cross site AJAX request

For cross site AJAX request we need following headers in host site:

Access-Control-Allow-Origin : http://example1.com, http://example2.com, ..
( it is necessary to mention requesting sites reference for localhost we can use and to grant access to all sites we can also use * )
Access-Control-Allow-Headers : Header1, Header2, ..
(we need to mention the permissions for headers send by other site)

Access-Control-Allow-Methods : POST, OPTIONS, ..(we also need to mention Request methods supported by our site for other sites GET is by default open)


SOAP is a simple and extensible schema(or format) of XML information exchange over HTTP, it is used for communication between applications. SOAP stands for Simple Object Access Protocol.

PHP Framework

Cake PHP

If you still need to write PHP4 compatible code, CakePHP is a great option. This PHP 4 & 5 MVC framework is one of the oldest and most popular on our list. Cake PHP has built up a reputation as a formidable and capable framework. It also has many avenues for support (groups, message boards, IRC) and excellent tutorials. CakePHP is a good framework that's easy to get into but one that you won't outgrow in a couple of weeks.

CakePHP's conventions are fairly strict, however, and it's not the most flexible framework available. This could be a plus if you want to guarantee consistency across the application regardless of the user. There are also built-in tools for unit testing, XML-RPC and feed parsing for integration with web services as well as scaffolding for rapid prototyping.

Zend Framework

The Zend Framework is for more experienced developers and those building enterprise-level applications. The framework is highly modular, meaning you can use as little or as much of the Zend code as you need. Several libraries can easily be extracted for stand-alone use. With Zend, you're not tied to the MVC pattern (though it is certainly an option), and there is a lot of built-in support for tasks such as integration with existing web services, localization and extensive unit testing.

Zend requires PHP 5.1.4+ but has multiple configuration options and excellent documentation. It's a framework with corporate backing and a strong community. You'll get long-term stability and fairly quick integration of new features, not to mention security updates tested by a team of professionals. While the Zend framework may be a large overhead for small projects, if you're building large-scale applications it is typically considered the framework of choice.


CodeIgniter is (as of v2.0) a PHP5.2+ MVC framework with a small footprint and great documentation. Often called a "beginners" framework because of its relative ease of use and short learning curve, CodeIgniter is nonetheless flexible and powerful. The framework has a large community surrounding it, so it's fairly easy to find an existing CI library for just about anything you could dream up. If you need to do it, chances are, someone out there already has.

CodeIgniter is best suited for content sites and small-to-medium web applications. You'll likely see a performance drop with very large numbers, but there is some built-in caching to help with that. If you're new to PHP frameworks or want something that can be picked up and learned in a few hours, CodeIgniter is one of the top frameworks to consider.


Symfony is one of the oldest PHP frameworks, and is designed for enterprise-level web applications. For all its power and performance, however, Symfony has a small footprint and is easy to configure on a variety of PHP hosting environments. Since it's been around for so long, you’ll find a lot of tutorials and books available on framework use, a perk for new users.

Symfony uses command line generators for quick project setups and automatic code generation, which may be new to some developers. However, they allow you to get up and running with your code in very short order. If you feel intimidated by this, don't worry. The Symfony's web site has a large collection of tutorials, showcase applications and screencasts to get you going.

The framework has all of the advanced features you'd expect of a system designed for the development of enterprise software. For example, it offers internationalization, URL routing, test suites, a robust templating engine and a powerful plug-in API for extending Symfony's features, or adding your own.


Kohana began as a fork of CodeIgniter, though it’s much more than a simple branch off. Like CI, Kohana strives to be a lightweight, easy-to-use framework that performs well for small-to-medium web applications and custom content management systems.

Unlike CodeIgniter, Kohana requires PHP 5.3. The developers have taken advantage of this by including some advanced functionality not present in Codeigniter. The 5.3 requirement also means less code can accomplish some of the same tasks with less concern over backwards comparability. While Kohana's documentation is a little lacking, it tends to implement features more cleanly. The community is active, so getting help shouldn't be an issue.


Yii is a highly modular, high-performance PHP5 framework designed specifically for developing web applications. Yii uses a lot of command line generators and tools to get you up and running quickly; therefore, it's best used by people that aren't intimidated by a terminal window. All those generators mean more commands to memorize, but once you do, you'll find that they greatly decrease the time it takes to set up and configure your application.

It's easy to extend Yii and add in your favorite third-party libraries. Yii also supports templating, themes and widgets, and includes tools for testing, libraries for internationalization and web service integration. Yii's performance is good and the automatic code generation makes it a great framework for rapid development. The framework is well-documented, but since so much of the work is done at the command line, it can be intimidating to some users.

Indian firms make profit of Rs 6 Lakh per employee

Indian Companies pay a salary of Rs 4.8 lakh to each of their employee on an average, but earn a profit of Rs 6 lakh per employee in return, says a new survey.

According to a study by Pricewaterhouse Coopers (PwC) -- Measuring Human Capital - Driving Business Results -- organisations in India pay an average remuneration of Rs 4.8 lakh and earn Rs 6 lakh of profit per employee, which makes the human capital return ratio on investment to 1.79 for organisations in the country.
Indian firms make profit of Rs 6 Lakh per employee

Besides, companies make an investment of Rs 7,000 on learning and development (L&D) per employee.

It further said that Indian companies make a pure profit of Rs 15 from every Rs 100-worth revenue generated by their each employee.
