Web scraping with Python (Part 2)

by Javier Collado | August 2009 | Content Management Open Source

This article by Javier Collado expands the set of web scraping techniques shown in his previous article by looking closely into a more complex problem that cannot be solved with the tools that were explained there. For those who missed out on that article, here's the link. Web Scraping with Python

This article will show how to extract the desired information using the same three steps when the web page is not written directly using HTML, but is auto-generated using JavaScript to update the DOM tree.

3D Vector Drawing and Text with Papervision3D: Part 2

by Jeff Winder Paul Tondeur | August 2009 | Open Source

In the previous part of the article by Jeff Winder and Paul Tondeur, we saw how to create a template class for the 3D text examples and add interactivity to 3D vector text and shapes. We also discussed about drawing vector shapes such as lines, circles, and rectangles. In this part, we will see how to draw lines with Lines3D and add interactivity to Lines3D lines.

3D Vector Drawing and Text with Papervision3D: Part 1

by Jeff Winder Paul Tondeur | August 2009 | Open Source

Papervision3D features a set of classes that allow for drawing vector graphics such as simple shapes and text. The method names that are used for drawing shapes are similar to those of the Flash drawing API such as lineTo() and curveTo(). Creating 3D text is also fairly simple because of a couple of easy-to-use classes.

In this two-part article by Jeff Winder and Paul Tondeur, we will discuss the following:

  • Creating 3D vector text
  • Creating font files for use in Papervision3D
  • Drawing 3D vector shapes and lines
  • Adding interactivity to 3D vector text and shapes

Simple process for PHP projects

by Samisa Abeysinghe | August 2009 | PHP

In this article by Samisa Abeysinghe, we will look into a process model that we can use as a starting point for the PHP projects that we are working on. The process is designed with the MVC framework based design model in mind. It is assumed that the workload is broken down based on the Model-View-Controller pattern, and team members are assigned to work on each layer based on that breakdown.

The process model clearly depicts how the separate concerns such as the data layer, the business layer, and the presentation layer can be worked on in parallel, and at the same time, how those separate concerns fit with each other to form the entire system. If you carefully evaluate this process model, there is no activity for system integration. So one might question how the separate layers would be integrated with each other. However, if you pay attention to the design and implementation details of each layer, you will notice the dependencies mentioned in each layer, which lead to the integration. For example, business logic implementation requires the concrete database design, as well as the data access layer. The final user interface implementation would be done on top of the business logic implementation. Therefore, the integration of these independent layers happens seamlessly, along the way, in the process. If the team follows the process as it is, the integration would result in naturally.

Agile Works Best in PHP Projects

by Samisa Abeysinghe | August 2009 | PHP

We are developing software for users, and we want to ensure that the software is really useful for the users. Over time, people working on this software have faced the same problem over and over again. Therefore, they have come up with a concept called agile development. In this article, we will explore the concepts of agile development and will also see how these can help us with the PHP projects.

In this article by Samisa Abeysinghe, we will cover the following:

  • What is meant by agility and how it can help
  • Extreme programming principles
  • Advantages of agile process models
  • Team agility
  • Agile process models
  • Agile principles for the PHP project team
