The installation is just the beginning of the work. It is very important to install OpenSIPS correctly from the source code. It can be installed much faster from the Debian packages or using the apt-get utility. However, installation from the source code is much more flexible as it allows you to select the modules to be compiled.
In this article,by Flavio E. Goncalves, we will see how to:
- Install Linux prepared for OpenSIPS
- Download OpenSIPS source and its dependencies
- Compile and install OpenSIPS with MySQL and RADIUS support
- Start and stop OpenSIPS
- Configure Linux systems to start OpenSIPS at boot time
In this article by Susan Smith Nash and William Rice, we will discuss the best way to organize your course content into lessons, along with how to build lessons using Moodle's unique capacity to let you use and reuse your materials, and to arrange and rearrange them. So, with that in mind, prepare to develop a strategy for creating lessons that can consist of many different elements, which could include readings, practice quizzes, questions for reflection, media, and peer interactions (discussions and student reviews). In this article, you'll learn how to select content so that it contains the appropriate depth, breadth, and level for your students. You'll also learn the best way to organize the material so that the sequence keeps the students on track, and allows them to develop successful learning strategies so that they perform well in their outcome assessments. Finally, this article will show you how Moodle's object-oriented philosophy of design allows you to go back and update, refine, revise, and retool your course.Read Lesson Solutions using Moodle 1.9: Part 1 in full
