Tizen Mobile OS - The Coming Giant

The biggest mobile OS revolution is happening around us now-a-days and we all know that the leading position is still owned to Android. Android is smashing around with its Jelly Bean updates and people are more talking about operating systems rather than brands. There was a time that almost all people go for Nokia mobiles. Now everyone is running for Android. The main challengers for Android are Windows 8 and iOS. Nokia is trying get back their smart phone market by their high end windows phone Lumia 920 which is going to release soon.

I need your attention to a coming mobile operating system – Tizen. Tizen is expected to change the current smart phone kingdom leading by Android. It is an open source, Linux based OS which will be released soon on Samsung smart phones. The main advantage is Tizen has HTML5 based apps which will lead to another phase of smart phone experience.

Tizen is a free and open source mobile operating system. Tizen is based on the Linux operating system backed by the Linux Foundation and represented in the industry by Tizen Association. The operating system incorporates a number of modules such as network management from the MeeGo project, a combination of the mobile operating systems Moblin, created by Intel, and Maemo, created by Nokia.

Development is led by companies gathered around Tizen Association, which is a not-for-profit consortium steered by a Board of Directors composed of Huawei, Intel, NEC, NTT DOCOMO, Orange, Panasonic, Samsung, SK Telecom, Sprint, Telefónica and Vodafone. The Tizen Association has been formed to guide the industry role of Tizen, including gathering of requirements, identification and facilitation of service models, and overall industry marketing and education.

It has an android like menu, a home button in the left top side, regular symbols in notification area etc. Settings menu have 2 different screens, one for preferred settings items and another for all. 



Tizen os is aiming on platforms like Mobile & PC, cross device, cross platform, tablets, netbooks, notebooks, smartphones, GPS smartnav, In-vehicle infotainment,Smart TV. Tizen Supports ARM and x86 platforms and its kernel is of type Monolithic (Linux).

Tizen is backed by the Linux Foundation and controlled (as of August 2012) by its two major contributors, Samsung and Intel. According to members of the current technical steering team, the development will be completely open. However, the project has stated that "Membership in most project teams (Release Engineering, QA, Program Management, etc.) is invite-only", and the first alpha version was released without development or design input from outside parties.

On 30 April 2012 Tizen released version 1.0, code-named Larkspur. The first devices running Tizen were initially planned for Q2 2012, and were intended to be highly flexible through the use of an HTML5-based API. On 7 May 2012, the American wireless carrier Sprint Nextel announced it had agreed to become part of the Tizen Association and plans to include Tizen-powered devices in their future lineup. 

For developers, Tizen has given an online documentation, which is still not complete.

You can download its SDK to your system.

Here is a collection of sample web applications for Tizen.

Official sites :,,

Let’s see their test device. It has a 720p HD screen, volume controls, power button and a mini usb port.

Samsung has tested Tizen on their Galaxy s3 handset. This shows how seriously Samsung is taking Tizen. Here is their Wi-Fi certification.

Let’s hope for even better operating systems which will give the normal users a good smart phone experience.

Git Based Wiki Implementation

A wiki implementation based on the Git, a Distributed Version Control System, is the academic project done by me during my MCA. It is a completely open source tools oriented wiki engine that has many powerful capabilities. 

We know, a wiki is a collection of various articles contributed by various writers around the world. There may be chances of updating an article with unwanted or abusing data. So we may need to revert the modified article to its previous state. We generally use a version control management system for that purpose. I used Git in my project for that purpose.

As Git is a powerful DVCS (Distributed Version Control System), the wiki engine is more efficient to keep track of the versions. Git is a open source tool that is  developed by the Linux developer team. Its more efficient with its powerful commands.

I am using SQLite3 as the database. Webpy is the framework used here. HTML and CSS is used for the user interface. Python is the language used to write the wiki engine. Markdown style is used for writing the articles. The project is completely developed under Linux platform.

Here is some screen shots of my project.

You can read following articles regarding my project.

ActionScript Tutorial

ActionScript is an object-oriented language originally developed by Macromedia Inc. (now owned by Adobe Systems). It is a dialect of ECMAScript (meaning it is a superset of the syntax and semantics of the language more widely known as JavaScript), and is used primarily for the development of websites and software targeting the Adobe Flash Player platform, used on Web pages in the form of embedded SWF files. The language itself is open-source in that its specification is offered free of charge  and both an open source compiler (as part of Adobe Flex) and open source virtual machine (Mozilla Tamarin) are available.

I am giving you a best tutorial for learning ActionScript. Download it here,
