Radian6 Overview - Social Media Monitoring Platform

Listening to social media is lot more than just collecting posts and monitoring buzz. You need insights, measurements, and the ability to act on the conversations you uncover.

Apple's Cloud Services - ?

Get ready for Apple’s new Cloud called “iCloud”!
It will definitely change the landscape of Mobile Cloud services!

It was reported in Gigaom that Apple has snapped up
As we all knew, Apple is gearing up for their upcoming Cloud services. The was a domain name owned by Linkoping, a Swedish-based desktop-as-a-service company, Xcerion. And now, service has been rebranded as CloudMe.

UPDATE: Just received a notification from MobileMe asking to upgrade my calendar to maintain syncing and calendar web access. It seems that the old MobileMe calendar will be discontinued in 7 days.
What does it mean? Most probably Apple is going to start migrating its MobileMe to iCloud very soon, eh? What do you think?

Back to Basics - The Difference between Unicast, Broadcast and Multicast

Unicast packets are sent from host to host. The communication is from a single host to another single host. There is one device transmitting a message destined for one receiver.


Broadcast is when a single device is transmitting a message to all other devices in a given address range. This broadcast could reach all hosts on the subnet, all subnets, or all hosts on all subnets. Broadcast packets have the host (and/or subnet) portion of the address set to all ones. By design, most modern routers will block IP broadcast traffic and restrict it to the local subnet.


Multicast is a special protocol for use with IP. Multicast enables a single device to communicate with a specific set of hosts, not defined by any standard IP address and mask combination. This allows for communication that resembles a conference call. Anyone from anywhere can join the conference, and everyone at the conference hears what the speaker has to say. The speaker's message isn't broadcasted everywhere, but only to those in the conference call itself. A special set of addresses is used for multicast communication.

Mobile Virtualization in action

Carrying two or more mobile phones is not unusual. People will often need one device for work and a second for personal use. The virtualization technology now allows a mobile device to act like its been split into two different phones and different usage.

Cloud Phone Concept

  • It started in year 2007 when Grid Computing was the "buzzword", I have this idea to use the normal consumer phones which utilize the power of grid for high-computation applications. 
  • The article "Building the Grid Computing Eco-System - All Users Can Compute" was never published. It was an internal company presentation but at that time nobody was interested about this concept.
  • Today - when people realized that even smartphones or Tablet PCs can't emulate the full power of computer, the idea of sending the phones to the Cloud came back.
  • The buzzword "Grid Computing" is now changed to "Cloud Computing" and now mobile telcos also embraced the idea of having applications in the Cloud.
  • The 2007 original article (PDF) written on July 8, 2007 can be downloaded HERE or HERE.
  • The era for "Cloud Phones" begins...

Cloud Phones - The Brain is Now in the Cloud

  • One the best example of SaaS (Software as a Service) in Mobile Computing is SoundHound.
  • Its a Music Recognition service which is hosted in the "Cloud".
  • The smartphones don't have the power and processing engine to process Millions of Music database very fast.
  • Thus, a simple command (press of some buttons), music can be easily recognized and you will get the Singer's name, Album, Youtube, lyrics etc.
  • No wonder people now coined a new name for smartphone that uses cloud computing - "Cloud Phones"
  • What do you think?
