Themes are among the most powerful features that can be used to customize a web site, especially in Plone. Using custom themes can help you brand your site for a particular corporate image; it ensures standards compliance and creates easily navigable layouts. But most Plone users still continue to use default themes as developing and deploying themes that are flexible and easily maintainable is not always straightforward.

  • About the theme
  • Creating a theme product
  • Altering the theme product's structure
  • Installing the theme product
  • Adjusting web site content to support the design

Building a News Aggregating Site in Joomla!

by Timi Ogunjobi | May 2010 | Joomla! Content Management Open Source PHP Web Development

Bad news is always good news for the press. This is why Vaughan Pyre has decided to take advantage of this fact and creates a website that will aggregate bad news and weird happenings from all over the world. In this article by Timi Ogunjobi, author of Joomla! 1.5 Site Blueprints, the content of the site will be entirely derived from Really Simple Syndication (RSS) feeds from several sources (each feed being automatically fetched and its items displayed on the website).

Weird Hap'nins requirements will be the need to:

  • Get external feed sources and allocate them to menu links on the website
  • Create the means to automatically fetch and display article items located in the feeds
  • Display the latest content from all feed sources on the front page

Use of macros in IBM Cognos 8 Report Studio

by Abhishek Sanghani | May 2010 | Enterprise Articles IBM

Cognos Report Studio is widely used for creating and managing business reports in medium to large companies. It is simple enough for any business analyst, power user, or developer to pick up and start developing basic reports. However, when it comes to developing more sophisticated, fully functional business reports for wider audiences, report authors will need guidance.

In this article, by Abhishek Sanghani, author of IBM Cognos 8 Report Studio Cookbook, we will show you  that even though macros are often considered a Framework Modeler's tool, they can be used within Report Studio as well. These recipes will show you some very useful macros around security, string manipulation, and prompting.

Easily Writing SQL Queries with Spring Python

by Greg L. Turnquist | May 2010 | Open Source

Spring Python takes the concepts of the Spring Framework and Spring Security, and brings them to the world of Python. It isn't a simple line-by-line port of the code. Instead, it takes some powerful ideas that were discovered in the realm of Java, and pragmatically applies them in the world of Python.

Spring (Java) provides many simple, easy-to-use functional parts to assemble applications instead of a monolithic framework to extend. Spring Python uses this same approach. This means we can use as little or as much Spring Python as we need to get the job done for each Python application.

In this article by Greg Lee Turnquist, Author of Spring Python 1.1, we will show you how to rapidly write pure SQL queries without dealing with mind-numbing boilerplate code. It also shows how Spring Python works nicely with ORM-based persistence.

Scaling your Application Across Nodes with Spring Python's Remoting

by Greg L. Turnquist | May 2010 | Open Source Web Development

Spring Python offers a clean cut way to take simple applications and split them out between multiple machines using remoting techniques that can be seamlessly injected without causing code rewrite headaches. Spring Python makes it easy to utilize existing technologies, while also being prepared to support ones not yet designed.

In this article by Greg Lee Turnquist, author of Spring Python 1.1, we will learn how:

  • Pyro provides a nice Python-to-Python remoting capability to easily create client-server applications
  • Spring Python seamlessly integrates with Python so that your application doesn't have to learn the API
  • You can convert a simple application into a distributed one, all on the same machine
  • It takes little effort to rewire an application by splitting it up into parts, plugging in a round-robin queue manager, and running multiple copies of the server with no impact to our business logic

User Authentication with Codeigniter 1.7 using Twitter oAuth

by Adam Griffiths | May 2010 | Open Source PHP Web Development

User authentication is an important part of many applications. Let's look at how we would utilize third-party authentication methods. oAuth is an open protocol for secure user authentication across APIs. It allows users to gain limited access to websites by using their Twitter credentials. It's a very sound method of user authentication, and doesn't take too much work to get going. Twitter oAuth is used by hundreds of third-party Twitter clients and mashups—just to give you an idea of how useful it can be.

In this article by Adam Griffiths, author of CodeIgniter 1.7 Professional Development, we will:

  • Learn how Twitter oAuth works
  • Create a library for authentication
  • Utilize the library in order to create an application to demonstrate how it works

User Authentication with Codeigniter 1.7 using Facebook Connect

by Adam Griffiths | May 2010 | Open Source PHP Web Development

In a previous article we covered User Authentication with Codeigniter 1.7 using Twitter oAuth. In this article by Adam Griffiths, author of CodeIgniter 1.7 Professional Development, we will continue our discussion on how we can utilize third-party authentication methods by using Facebook Connect.

Facebook Connect is just like Twitter oAuth, but for Facebook accounts. It doesn't use the oAuth protocol, so its workings might seem slightly different to developers. To users, however, the difference is marginal. Just like in Twitter oAuth, users do not need to enter any of their account credentials on your website or application—it is all handled by Facebook.

Setting up a Complete Django E-commerce store in 30 minutes

by Jesse Legg | May 2010 | e-Commerce Open Source

In order to demonstrate Django's rapid development potential, we will begin by constructing a simple, but fully-featured, e-commerce store. The goal is to be up and running with a product catalog and products for sale, including a simple payment processing interface, in about half-an-hour. If this seems ambitious, remember that Django offers a lot of built-in shortcuts for the most common web-related development tasks. We will be taking full advantage of these and there will be side discussions of their general use.

In addition to building our starter storefront, this article aims to demonstrate some other Django tools and techniques. In this article by Jesse Legg, author of Django 1.2 e-commerce, we will:

  • Create our Django Product model to take advantage of the automatic admin tool
  • Build a flexible but easy to use categorization system, to better organize our catalog of products
  • Utilize Django's generic view framework to expose a quick set of views on our catalog data
  • Finally, create a simple template for selling products through the Google Checkout API
