Buttons, Menus, and Toolbars in Ext JS

by Colin Ramsay Shea Frederick Steve 'Cutter' Blades | June 2009 | AJAX Open Source

The unsung heroes of every application are the simple things like buttons, menus, and toolbars. In this article by Shea Frederick, Steve 'Cutter' Blades, and Colin Ramsay, we will cover how to add these items to our applications.

Sakai Web Services: Connecting to the Enterprise (Part 1)

by Alan Mark Berg Michael Korcuska | June 2009 | Open Source

From the very beginning, it was clear that Sakai needed to exist in universities at enormous scales, supporting hundreds of thousands of students. With requirements changing and evolving, and ever-increasing user expectations, Sakai had to be able to connect with a multitude of external systems. When Sakai was designed, the specifics of the majority of the connected systems were not knowable. To adapt to these tough circumstances, Sakai supplies web services that are easy to hook into or to write. Sakai exposes services for creating and maintaining users, sites, and groups. These services are easily extensible to include any part of the Sakai framework.

In this two-part article by Alan Mark Berg and Michael Korcuska, we will look at the two main types of web service, SOAP (Simple Object Access Protocol) and Representational State Transfer (REST) (http://microformats.org/wiki/rest). We will cover already-existing web services and describe how to hook into them. If you follow the examples, you will be able to write and deploy your first service. Lastly, this article includes a few simple client-side Perl scripts that create new users using both the SOAP and RESTful approaches.

Putting Sakai to Work

by Alan Mark Berg Michael Korcuska | June 2009 | Open Source

Sakai is an open source, web-based, collaboration learning environment (CLE) that is focused primarily on higher education.

Games of Fortune with Scratch 1.4

by | June 2009 | Open Source

In Scratch it is easy to create projects that incorporate dynamic information using variables. However, variables have a limitation; they store only one value at a time. Sometimes, we want a variable to store multiple values.

Welcome to lists. In Scratch, a list allows us to associate one list (a variable) with multiple items or values in much the same way we create a list before going to the grocery store. In this article by Michael Badger, we will take a trip to the fortune-teller to demonstrate lists, and you'll learn how to:

  • Store and retrieve information in lists
  • Add and remove items from the lists
  • Keep track of items in a list by using a counter
  • Identify intervals using the mod block
