Users, Profiles, and Connections in Elgg

by Mayank Sharma | April 2008 | MySQL Open Source PHP

Ever been to a night club on a Monday morning? There's you, there are chairs, and the potential to host a party on the weekend. There are lots of buttons, lots of potential, but no one there except you. Unlike a night club, you don't have to wait for the weekend to host your friends on Elgg. Invite them as soon as you're done setting up the software. Elgg is designed to make it easier for you to invite people. If you've ever setup a blog or rolled out your own website, how long did it take before you could invite your friends over? You had to put up all sorts of content to indulge them, and also fiddle around decorating the portal so that it doesn't look dull.

That's where a social network is different from a regular website. Websites follow a two-way, one-to-many style of interaction, where the owner of the website, or blog, talks to all his visitors who respond with their comments, either on the website, or via e-mail. In this article by Mayank Sharma, we discuss about social networking software that follows a many-to-many style of interaction. Members interact with each other, and create their own content, which is then shared with all. This is then discussed and commented on by everyone. The owner of the site is like the perfect host. They mingle, discuss with everyone, but don't stamp their authority, unless you're naughty. They're like every other member, except for the fact that they own the place. Sounds familiar? So, you don't have to worry about content before inviting your friends. Your friends bring their own content.

Routing Rules in AsteriskNOW - The Calling Rules Tables

by Nir Simionovich | April 2008 | Linux Servers Networking & Telephony Open Source

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

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.

Customizing the Menus Menu in Joomla!

by Hagen Graf | April 2008 | Joomla! MySQL Content Management Open Source PHP

There are numerous menus in the front end of every application. They are often displayed as standalone boxes. The menu items are generally arranged one below the other. Menus can also be integrated into the design horizontally so that at first sight they aren't even recognizable as cohesive menus. CSS menus, which can even be transparent, are very cool.

These menus and the menu links are dynamically administered in Joomla! from database content in the Menus work area. Joomla! has six different menus in the sample data. (main menu, top menu, other menu, user menu, example pages, and key concepts) In this article by Hagen Graf, we will discuss administering, creating and managing menus in Joomla!

Creating a Simple Report using BIRT

by John Ward | March 2008 | Java Open Source

BIRT, which stands for Business Intelligence and Reporting Tools, is an Eclipse-based open-source reporting system for Java and J2EE-based web applications. Including the word "Tools" in the acronym is appropriate, since BIRT is in fact a collection of development tools and technologies used for developing reports utilizing the BIRT runtime framework component on your application server. BIRT isn't essentially a product, but a series of core technologies on top of which products and solutions are built, similar in fashion to the Eclipse framework.

The BIRT Report Designer, which is the most visible and familiar product built with the BIRT framework, is an Eclipse plug-in that utilizes BIRT technologies to allow users to design reports in the BIRT document format.

In this article by John Ward we will create a simple report by first setting up a simple project.

Term Extraction Tasks in SQL Server Integration Services

by Dr.Jay Krishnaswamy | March 2008 | .NET Microsoft

Microsoft SQL Server's SQL Server Integration Services is a comprehensive, full featured tool for processing data in the back-end storage locations. Extraction of attributes in a body of text is an important task while mining data and the SSIS provides just the required transformation - Term Extraction, to accomplish this task. SSIS looks through the presented text document and sorts out terms. By terms are meant specifically nouns, noun phrases, and both nouns and noun phrases. You also have the flexibility of limiting extracted terms based on their frequency of occurrence. For example you could configure the task in such a way that you can capture terms that are repeated in the body of text a certain number of times.

This tutorial by Jayaram Krishnaswamy shows a simple example of extracting terms from a body of text.

Tapestry 5 Advanced Components

by Alexander Kolesnikov | March 2008 | Content Management Java Open Source

There is a significant number of Tapestry components that we can use to build sophisticated and functionally rich interfaces. It so happens however, that many web applications have certain patterns repeating on their pages. For example, they have tables that display different data or they have forms that accept user input and then put the submitted details into some kind of JavaBean object.

Wouldn't it be convenient to have such repeating patterns already implemented as components, ready to be dropped onto a page? It certainly would, and the current version of Tapestry 5 already comes with a few components of this kind. They are great effort savers for us, and in this article by Alexander Kolesnikov we are going to introduce them and use them in our Celebrity Collector application.

Cooking XML with OOP

by Hasin Hayder | February 2008 | MySQL Open Source PHP

XML (Extensible Markup Language) is a very important format for storing multi‑purpose data. It is also known as universal data format, as you can represent anything and visualize the data properly with the help of a renderer. One of the biggest advantages of XML is that it can be converted from one form of data into another easily with the help of XSLT. Also, XML data is highly readable.

One of the great blessings of PHP5 is its excellent support to manipulate XML. PHP5 comes bundled with new XML extensions for processing XML easily. You have a whole new SimpleXML API to read XML documents in a pure object-oriented way. Also, you have the DOMDocument object to parse and create XML documents. In this article by Hasin Hayder, we will learn these APIs and learn how to successfully process XML with PHP.

Why Do We Need Specialist Security Distros?

by Mayank Sharma | February 2008 | Linux Servers Open Source

Many popular distributions, community-oriented and otherwise, take security very seriously. They have dedicated security teams that go over individual packages before they're rolled into a final release. To make sure you don't have any loose ends, these distributions and many other individual Open Source projects also publish an endless stream of security advisories and updates. Add to this security mechanisms like SELinux, AppArmor, and the upcoming TOMOYO Linux, and SMACK, and you know they mean business. So what room does this leave for specialist security distros?
