Sencha Touch Jump Start

The PHP Cross Platform Web Applications course I teach in HIT coveres some of the newest web technologies. The next meeting covers Sencha Touch. It is a Java Script library that allows us to develop web applications optimized for touch screen devices, such as mobile telephones and tablets. In order to assist my students with the understanding of this topic I chose to create two video clips that explain how to download Sencha Touch, how to execute the code samples it includes and how to develop a simple Hello World application.

The source code is available for free download in my community version for the Sencha Touch course I developed. You can find it at www.abelski.org.

The Singleton Design Pattern in PHP

The singleton design pattern provides us with a solution for ensuring that a given class won't be instantiated more than than one. This video clip explains it using a code sample in PHP.

Unlike web applications developed in .NET when using PHP we cannot maintain the objects we create on the server side in between the requests. Therefore, many will claim that implementing this pattern in PHP is considered as an anti pattern. You can find the source code available for free download in my PHP Design Patterns course at www.abelski.org.
