CONS: No buffer progress bar, user cannot select audio quality, no lock screen controls, iffy search sometimes shows irrelevant results


HUNGAMA MYPLAY

Hungama offers over 4,50,000 songs, videos, ringtones and wallpapers but the cluttered interface makes it difficult to find updated content. Search is accessible only though the options interface and thankfully, shows relevant results. However, there is no option to get detailed artist or album information.

CONS: Advertisements play each time the app opens or exits, in app advertisements, no selectable audio quality, cannot skip ahead or back in a song

RAAGA

Raaga offers music in 18 languages but no international content. You also need to go through a time-consuming signup & activation process after which you can have playlists synced between your device and web portal. The interface is easy-to-use but slow when navigating between menus.

PROS: Easy-to-use interface, fast search, on-screen volume controls, 'shake to skip' feature lets you skip songs using the device's accelerometer

CONS: Compulsory sign-up required, no login via Facebook, slow interface, cannot adjust streaming audio quality, not much new content

Great online services for free music streaming


SAAVN

With Saavn, you need to first select a language to see songs. You can view either new releases or weekly top 15-songs from the main window. The app automatically adds all the songs you select into a playlist visible under the music player — making it easier to keep a track of your library.

PROS: User controlled audio quality (highest quality is 128 kbps), playlist synced between app and web portal, song buffer indicator

CONS: In-app advertisements, no way to browse through different genres, no international content, no social network discovery or sharing
IF YOU WANT to purchase songs for offline listening, you can buy whole albums or individual songs from places like Flyte, iTunes, Nokia Music, Raaga and Hungama. Prices per song usually range from Rs 6 to 15.

AUDIO STREAMING doesn't completely do away with piracy. In-line audio recorders like SmartRecorder or MooO can record any music stream that you're playing on your computer.

THE BITRATE of a song is directly related to audio quality: higher the bitrate, higher the quality. The problem arises because a high bitrate song also leads to higher data usage. A balance between the two is hard to find.

CREATING PLAYLISTS is the easiest way to keep track of the music you want. So, pick one of the services, sign in, create your playlists and your music will be the same on all your devices.

Jini TM :The End To Protocols As We Know Them



Jini technology, based on Java technology,enables digital services to simply connect together.

What is Jini?

Jini (pronounced like geini ), also called Apache River, is a network architecture for the construction of distributed systems in the form of modular co-operating services.
Originally developed by Sun, Jini was released under an open source license  Responsibility for Jini has been transferred to Apache under the project name "River" 
         Software layer (48kB) to describe services to the net
         Runs on all Java Virtual Machines (JVM) on any device (from mainframe to toaster)
         Only the Front-End of the service is transmitted---Distributed Computing
         End of all Protocols as we know them
         Resilience: does not assume that networks always work
History of Jini
Sun R&D project by Bill Joy, and Jim Waldo with Ann Wollrath, Ken Arnold and Bob Schleifer in Mid-1960‘s: David Gelernter (Yale) developed a programming language called LINDA

Linda and JavaSpaces
JavaSpaces: implementation of the ideas behind LINDA but greater use of recent advances in object technology, namely Java
The work at Yale focused mainly on data, but today we can just move objects in and out of JavaSpaces [. . .] JavaSpaces is essentially a facility for communicating tasks out and bringing jobs back'' (James Gosling).


Scope at that Era

·       Network centric development
·       Focus on business logic and accessibility
·       Capacity planning is an oxymoron
·       Supply chain integration and auctioning as examples of new business model
·       Everything is mission critical
·       Simplicity!
