Roles and Permissions in Moodle Administration: Part1

In this article by Alex Büchner, we will introduce roles—a complex but powerful subject. Roles define what users can or cannot see and perform in your Moodle system. The article later explains assignment of roles, modifying them, over riding them, creating custom roles with example and finally testing those new roles to perform a reality check. We also explain how to resolve permission conflict in Moodle's Roles.

In the first part you will:

• Assign roles to different users in different contexts.

In the next part you will:

• Modify roles and create new ones, including a role for parents or mentors.
• Manage a range of administrative role-related settings.

Routing Rules in AsteriskNOW - The Calling Rules Tables

Philosophy: A route of many roads leading from nowhere to nothing.

While it appears that Ambrose Bierce has a little respect for Philosophy in general, he would surely refer to calling routing as—roads leading from a single point to multiple points, or something similar. The purpose of the "Calling Rules" is to define the methodology by which calls are routed from the PBX to the outbound world.

This article by Nir Simionovich deals with the routing rules in AsteriskNOW and the Calling Rules tables.

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

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.
