Android 4.1.x Jelly Bean Officially Released

Google announced the next Android version, 4.1 Jelly Bean on 27 June 2012. It is an incremental update with the main focus of improving the user interface, both in terms of functionality and performance, the latter involving "Project Butter" which uses touch anticipation, triple buffering, extended vsync timing and a fixed frame rate of 60fps to create a fluid and "buttery" smooth User Interface.

Jelly Bean - Android 4.1 OS

Jelly Bean user interface is largely the same as Ice Cream Sandwich, but now widgets will resize automatically when you drop them onto a crowded home page. Then, by moving the blue points you can make it smaller or change its shape.


Android 4.1 Jelly Bean includes these features with the existing Android 4.0.4 ICS

• Vsync timing across all drawing and animation done by the Android framework, including application rendering, touch events, screen composition and display refresh
• Triple buffering in the graphics pipeline
• Enhanced accessibility
• Bi-directional text and other language support
• User-installable keyboard maps
• Expandable notifications
• Automatically resizable app widgets
• Multichannel audio
• Bluetooth data transfer for Android Beam
• Offline voice dictation

Android OS Naming in Different Releases

I dont know how many of you aware of android os naming convention. Common practice in all software industry is that they will provide different name for different releases of their product. Usually they will give different name for main releases (There is a major functionality changes on previous release) and not for patches. Likewise Android OS also named in different releases. Special here is Google using alphabetical order to name their android OS.

Here I listed table for android versions with its release name and release date.

Version	Release Name	Release date
Pre(1.0)*	Astro	Sep 28,2008
Pre(1.1)*	Bender	Feb 09,2009
1.5.x	Cupcake	Apr 30,2009
1.6.x	Donut	Sep 15,2009
2.0.x	Eclair	Oct 26,2009
2.2.x	Froyo	May 20,2010
2.3.x	Gingerbread	Dec 06,2010
3.x.x	Honeycomb	Feb 22,2011
4.0.x	Ice Cream Sandwich	Oct 19,2011
4.1.x	Jelly Bean	Jun 27, 2012

* The pre-release versions of Android were dubbed Astro and Bender, but these names could not ultimately be used for trademark reasons. But officially trademarked this as Android.

Easiest Way To Set Up Linux On Top Of Existing OS

Virtual Platform

VMplayer is software developed by vm-ware, provides virtual environment on top of any existing operating system. Virtual environment in the sense, the same physical hardware is shared to the operating system installed inside the VMPlayer (guest) with hiding existing operating system (host). So if anything happens inside the VMplayer will not affect main operating system where you installed VMplayer. This software is absolutely free of cost from vm-ware but you have to register an account at vm-ware to download the software.

VMplayer supports many guest operating systems on a single host operating system and keeps each guest OS files in a single file with extension vmdk on host machine. These vmdk files can be transferrable to any machine and can be reusable without having any configuration.

  

Trend sigma website offers free vmdk files for various linux operating systems. User can download any linux vmdk file from their site to use OS. This avoids manual installation effort for individuals.

Note: Virtualbox is open source software works similar to vmware.

Follow the Steps to Setup Linux

1. Download VMPlayer from Vmware website.
2. Install VM player on top of your existing windows OS.
3. Download vmdk zip files for any Linux.
4. Extract zip file and keep extracted file in permanent place.
