I discuss common fraud scenarios and things to be wary of when using PayPal as a seller.
It have been playing with Fujifilms 16 megapixel, 15x optical zoom camera the F550EXR and I am thoroughly impressed with the performance of this pocket sized baby.

A "webapp" short for web application is a computer application that works over the internet in the Internet browser. It does not require installation of any software except for the Internet browser itself. Web applications are a relatively new concept. There are some popular webapps around, the most well known are perhaps Facebook and Flickr and lesser known Trello. The success of these webapps has prompted some companies to attempt to convert their traditional client only or client-server applications into webapps. But writing webapps can be far more challenging than writing traditional client only or client-server applications. So before you start take a look at these gotchas and ensure you are well prepared for them.

When you buy software, how can you tell if it is genuine? And why should you be bothered if it is not? I share a recent experience.
While the 2010 movie The Last Airbender had very little success with the critics and audiences, tracing its roots leads to the original animated series titled Avatar: The Last Airbender which is nothing less than a masterpiece in animation and creative storytelling. Set in an alternate universe the world is divided into four nations each having the ability to control one of the four elements Fire, Air, Water and Earth.

But the Avatar has disappeared and has not been seen for a 100 years.
