The Different Types of Q Replication

by Pav Kumar-Chatterjee | November 2010 | Enterprise Articles IBM

In the world of DB2 replication, we have two main options—SQL replication and Q replication, both of which involve replicating between source and target tables. The choice of replication solution depends on a number of factors, of which the fundamental ones are:

  • Type of source
  • Type of target
  • Operating system support

In this article by Pav Kumar-Chatterjee, author of IBM InfoSphere Replication Server and Data Event Publisher, we look at the different types of replication available, namely the base replication methods of unidirectional, bidirectional, and peer-to-peer.

The easy to install Gentoo with bling-bling. No, the other one!

by Mayank Sharma | March 2010 | Open Source

Gentoo is a source-based Linux distribution that helps users put together a streamlined custom system. But Linux users spoiled by the see-before-you-try Live CDs would often shy from Gentoo. Then along came Kororaa. Kororaa is a pre-configured binary Live CD for Gentoo Linux that also features an installer. Kororaa's package selection not only makes it an all-round Linux desktop, but has also ruffled feathers of Linux kernel developers.

Kororaa's developer Chris Smart probably had the best tutors introduce him to Linux, including Andrew Tridgell, the author of Samba file server. In this discussion, Chris talks about why he developed Kororaa, why people interested in learning Linux should use Gentoo, and his new project to help users make the move to Free and Open Source software.

Read more about this in Packt Columnist Mayank Sharma's interview with Chris Smart.

The Economics of Open Source Donations

by Mayank Sharma | August 2007 |

Donations play a crucial role in supporting Free and Open Source Software projects. At times readers will write in to share their positive experience with a utility or program or a distribution that I have written about. Now don't confuse them with your average technical-bent-of-mind Linux user. These are accountants, home-office businessman, and even carpenters and plumbers, who've saved a lot of money thanks to open source software. And they have one question in mind -- how do I help the person behind the program?

This month, Packt columnist and open source enthusiast Mayank Sharma explores the economics behind open source projects, what they do with their donations and how crucial they can be to their future.

The IBM SOA Programming Model

by Matjaz B. Juric | November 2010 | BPEL Enterprise Articles IBM SOA

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.

The Login Page using Ext JS

by Loiane Groner | July 2013 | Open Source Web Development

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

The Magic

by Alex Knol | December 2013 | Open Source

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.

The Media module

by Liran Tal | August 2013 | Drupal Open Source

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.
