by Ivan Idris | March 2013 | Games Open Source

In this article by Ivan Idris, author of Instant Pygame for Python Game Development How-to , we will create a simple game. As is traditional in the world of programming, we will start with a Hello World! example. It's not a game per se. It's important to notice the so-called main game loop where all the action happens and the usage of the Font module to render text. In this program we will manipulate a Pygame's Surface object, that is used for drawing and we will handle a quit event.

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.
