When embarking on an SOA journey, developers often come across the daunting realities of multiple programming languages, technologies, data format representation, implementation framework options, and such others, when they build services, use services, and develop solutions that aggregate services. The focus should be on programming the business and service design, not on the technology of the underlying implementation.
In this article by Matjaz B. Juric, author of the book WS-BPEL 2.0 for SOA Composite Applications with IBM WebSphere 7, we will take a look at IBM's SOA programming model.Read The IBM SOA Programming Model in full
In this article by Biru Chattopadhayay, author of Getting Started with Oracle Tuxedo,we will discuss various important built-in features (security, data-dependent routing, encryption, and so on) that come with the Tuxedo system and how these features can be used to make your application more secure, effective, and responsive to address your business needs. These features are configurable, and there is no need to do any custom development, hence they are very cost-effective and easy to use. We will also discuss responsibilities of Tuxedo administrator for administering the Tuxedo queue.Read The important features of Tuxedo in full
In this article by John Adams, author of Learning Kendo UI Web Development, we will cover the following topics:

The article The Login Page using Ext JS by Loiane Groner, author of the book Mastering Ext JS, talks about developing a login page for an application using Ext JS.
It is very common to have a login page for an application, which we can use to control access to the system by identifying and authenticating the user through the credentials presented by him/her. Once the user is logged in, we can track the actions performed by the user. We can also restrain access of some features and screens of the system that we do not want a particular user or even a specific group of users to have access to.
In this article, we will cover:
- Creating the login page
- Handling the login page on the server
- Adding the Caps Lock warning message in the Password field
- Submitting the form by pressing the Enter key
- Encrypting the password before sending to the server
It is time we explain some of the inner workings of Angular. Angular does some neat things for us. It saves us from having to write a bunch of boilerplate code. In this article written by Alex Knol author of the book Dependency Injection with AngularJS, we will see the magic of Angular.
Dependency Injection is baked into AngularJS and heavily used throughout. Another feature is a built-in subset of a jQuery functionality called jQLite. It contains all the necessary functions to make AngularJS run without jQuery and has the exact same interface. If jQuery is available in your application, it will be used instead. Angular also takes the burden of bootstrapping your application, which will be covered later in this article.Read The Magic in full
In this article by Liran Tal, the author of the book Drupal 7 Media, mentions that in previous versions of Drupal, the basic image field type didn't exist by default nor did another facet of image handling—the Imagecache module, which enabled the management of different image pre-sets (thumbnail, large, and so on). As we've seen with the Memo content type, this is no longer the case in Drupal 7, and at least a very basic support for images that already exist.Read The Media module in full
Alfresco 3 is one of the most versatile open source Enterprise Content Management (ECM) platforms. This is a real open source alternative to commercial product such as Microsoft SharePoint and EMC Documentum. It is also very well designed and suitable to be customized and extended. The open source adoption allows developers to contribute on the project and that's why you can find more than 240 extensions in the Alfresco Forge.
In this article by Ugo Cei and Piergiorgio Lucidi, authors of the book, Alfresco 3 Web Services, you will learn:
- How to properly design Web Scripts using the Model-View-Controller pattern
- How to configure a Web Script for things such as authentication, transactionality, and cacheability
- How clients can request a specific response format
- How to deploy Web Scripts in Alfresco
The Search pages in the Database or Table view are intended for single-table lookups. This article by Marc Delisle, covers the multi-table Query by example (QBE) feature available in the Database view.
Many phpMyAdmin users work in the Table view, table-by-table, and thus tend to overlook the multi-table query generator, which is a wonderful feature for fine-tuning queries. The query generator is useful not only in multi-table situations but also for a single table. It enables us to specify multiple criteria for a column, a feature that the Search page in the Table view does not possess.Read The Multi-Table Query Generator using phpMyAdmin and MySQL in full
An HTTP server is primarily a piece of software that will deliver web pages to clients when requested. These web pages can be anything from a simple HTML file on disk to a multicomponent framework delivering user-specific content, dynamically updated through AJAX or WebSocket. NGINX is modular, and is designed to handle any kind of HTTP serving necessary.
In this article by Dimitri Aivaloitis, author of Mastering NGINX , we will investigate the various modules that work together to make NGINX such a scalable HTTP server. The following topics are included in this article:
The HTTP core module
Using limits to prevent abuse
Streaming media files
Using NGINX with PHP-FPM
Wiring NGINX and uWSGI together

- How a scene graph is organized
- The different 3D spaces we can operate in
So let's get on with it.Read The Ogre Scene Graph in full
