Creating Tax Rules in Magento

by William Rice | March 2009 | Beginner's Guides MySQL e-Commerce Open Source PHP

In this article by William Rice, we will see how to create Tax Rules in Magento. In the real world, the tax rate that you pay is based on three things: location, product type, and purchaser type. In Magento, we can create Tax Rules that determine the amount of tax that a customer pays, based upon the shipping address, product class, and customer class.

When you buy a product, you sometimes pay sales tax on that product. The sales tax that you pay is based on:

  • Where you purchased the product from. Tax rules vary in different cities, states, and countries.
  • The type of product that you purchased. For example, many places don't tax clothing purchases. And, some places tax only some kinds of clothing. This means that you must be able to apply different tax rates to different kinds of products.
  • The type of purchaser you are. For example, if you buy a laser printer for your home, it is likely that you will pay sales tax. This is because you are a retail customer. If you buy the same printer for your business, in most places you will not pay sales tax. This is because you are a business customer.
  • The amount of the purchase. For example, some places tax clothing purchases only above a specific amount.

Scalix and Security

by Markus Feilner | March 2009 | Linux Servers Open Source

The standard setup of the Scalix server may be satisfactory for most installations, but if you are running Scalix on an internet site or if your local server is available from the Internet, extended security measures have to be taken. In this article by Markus Feilner, we will deal with several recommendations that make your Scalix server safe—like minimizing the number of services running and listening. We will set up a firewall which allows the Scalix users to connect to. After that, we will set up Stunnel to provide SSL-encrypted Scalix services. Then, we will use OpenVPN to protect the server. Last but not least, we will have a look at the services running and discuss advanced possibilities of securing the server.

Adding Worksheets and Resources with Moodle

by Mary Cooch | March 2009 | e-Learning Moodle Open Source

In this article by Mary Cooch, we will learn how to save energy. Not only our own, but the world's too! Moodle's main attraction, to many teachers, is the fact that you can upload all of those worksheets that you hand out in class (and that your students lose). When you've done it once, they are there for as long as you need them—so you don't have to find and print them off the next time you do that topic, and fewer trees will be felled in the name of education!
In this article, we shall:

 

  • Put an information sheet about the River Thames into Moodle
  • Load a whole week's slideshows about River processes into Moodle in a neat folder
  • Make a click here type link (this is known as a hyperlink) to the River Thames web site
  • Create a worksheet about flooding by typing it straight into Moodle
  • Make our page a bit prettier now that we've got some real stuff on it

Your First ASP.NET MVC Application

by Maarten Balliauw | March 2009 | .NET Microsoft

When downloading and installing the ASP.NET MVC framework SDK, a new project template is installed in Visual Studio—the ASP.NET MVC project template. This article by Maarten Balliauw describes how to use this template. We will briefly touch all aspects of ASP.NET MVC by creating a new ASP.NET MVC web application based on this Visual Studio template. Besides view, controller, and model, new concepts including ViewData—a means of transferring data between controller and view, routing—the link between a web browser URL and a specific action method inside a controller, and unit testing of a controller are also illustrated in this article.

Using Business Rules to Define Decision Points in Oracle SOA Suite: Part 1

by Matt Wright | March 2009 | Architecture & Analysis BPEL SOA Web Services Java Web Development

In this two part article by Matt Wright, we will look at how we can use the Business Rules engine to externalize rules from a BPEL process into a separate decision service. Once we've done this, we will know how to invoke the rule from a BPEL process. At run time there may be many potential paths through a BPEL process, controlled by conditional statements such as switch or while activities. Typically the business rules that govern which path to take at any given point are written as XPath expressions embedded within the appropriate activity.

Although this is an acceptable approach, we often find that while the process itself may be relatively static, the business rules embedded within the activities may change on a more frequent basis. This will require us to update the BPEL process and redeploy it even though the process flow itself hasn't changed. In addition, by embedding the rule directly within the decision point, we often end up having to re-implement the same rule every time it is used, either within the same process or across multiple processes. Apart from being inefficient, this can lead to inconsistent implementations of the rules as well as requiring us to update the rule in multiple places every time it changes.
