Audio Fields in Drupal

by Aaron Winborn | July 2009 | Drupal Open Source

In this article by Aaron Winborn, we'll go through the FileField module. This is a useful module if you want to have an easily configured solution, in many situations, there are some benefits from using the FileField module instead. It's light-weight, it's flexible, and it's easy to customize. It may also be easier to add support for players other than the 1PixelOut and XSPF players distributed with Audio.

Additionally, as of this writing, the Drupal 6 version of the Audio module wasn't quite ready for production. But I am confident it will be soon, if not already.

Finally, there may be specific reasons for wanting to choose a FileField solution over the Audio module. Similar to the quandary of whether to use the Image module or Image Field, the most common reason would probably be to allow multiple audio files to be attached to a node, or to allow audio fields to be associated with other types of nodes. (Note that the Audio module is also bundled with the Audio Attach module, which might be a solution for that as well.)

Oracle Wallet Manager

by Hector R. Madrid | July 2009 | Oracle

In this article by Hector R. Madrid, we will discuss about the Oracle Wallet Manager. The Oracle Wallet Manager (OWM) is the tool used by Oracle to manage the authentication processes. It is a key tool for managing most of the authentication and security related tasks in an Oracle environment, this includes; authenticating users, providing SSL communication, and configuring the Transparent Data Encryption (TDE) feature, among others. There are two modes to work with the Oracle Wallet, the first one is by using the Java Oracle Wallet Manager console and the second one is by means of the mkwallet command line version, this method is suitable for batch processing. The Wallet is a very sensitive element; there are several ways to store it, not only in its file at the file system level, but also in the registry (for Windows platforms only). It can also be stored in an LDAP compliant directory.

Debugging REST Web Services

by Samisa Abeysinghe | July 2009 | Architecture & Analysis MySQL PHP Web Development

Learning how to figure out why things are going wrong is one of the key aspects of developing software. We call it debugging. While dealing with REST services and clients, things can go wrong and it would help a great deal to know how to find out what is causing the problems.

In this article by Samisa Abeysinghe, we will look into the techniques such as message capturing and analyzing to get to know if things are going fine, and if not, what sort of problems are causing trouble.

Getting Started with Scratch 1.4 (Part 2)

by | July 2009 | Open Source

In this two-part article by Michael Badger, we will get comfortable working with Scratch by covering some basic concepts. Each Scratch project contains sprites with costumes, scripts, blocks, and a stage with backgrounds. In the first part, we built a couple of sample scripts to demonstrate how we can control the sprites in a project. For example, we used motion to move the sprites and forever loops to keep the sprite moving.

In this part of the article, we will use broadcast messages to coordinate the actions of multiple sprites. We will conclude this article by sampling and remixing projects from Scratch's sample projects and from the Scratch web site.

Key features among them include rich media integration, responsiveness, real-time, offline capabilities and a desktop/web deployment model.

There are several tools/frameworks available today to develop RIAs. One of the leading frameworks that has garnered a lot of attention and developer interest over the last couple of years is the Flex Framework from Adobe Systems.

This article by Romin Irani introduces the RIA development framework Flex and its development IDE Flash Builder 4 (FB4) to the readers. The article covers the following:

  • What is Flex Ecosystem
  • Setting up the Development IDE, Flash Builder Beta 4

Drools JBoss Rules 5.0 Flow (Part 1)

by Michal Bali | July 2009 | Java Open Source

Every non-trivial business process needs to make complex decisions. A rule engine is the ideal place for these decisions to happen. However, it is impractical to invoke a rule engine from a standard workflow engine. Instead, if we take a rule engine and add workflow capabilities, we have an ideal tool to model complex business processes—Drools Flow.

In this two-part article by Michal Bali, we'll look at Drools flow in detail. We'll build a loan approval process and cover the advanced concepts of a ruleflow like faults, subflows, and decisions.

Optimizing Lighttpd

by Andre Bogus | July 2009 | Linux Servers Open Source

This article written by Andre Bogus will help us make Lighttpd work even faster. Before we start optimizing our Lighttpd installation, there are some things to consider such as where is Lighttpd going to run?

The most tested system with perhaps the most optimized backend is Linux. So if we need to squeeze every little request per second out of a server, it is a sure guess. In fact, apart from Linux, all systems except Windows are quite capable of delivering good performance.
