LINQ to Objects

by N Satheesh Kumar | December 2007 | .NET Microsoft

LINQ to Objects means that we can use LINQ to query objects in a collection. We can access the in-memory data structures using LINQ. We can query any type of object that implements the IEnumerable interface or IEnumerable, which is of generic type. Lists, arrays, and dictionaries are some collection objects that can be queried using LINQ.

In this article, author N. Satheesh Kumar shows us how to query different objects using LINQ operators and avoid having to use the looping method to filter the values in a collection.

CodeIgniter and Objects

by David Upton | December 2007 | MySQL Open Source PHP

Objects confused me when I started to use CodeIgniter. I came to CodeIgniter via PHP 4, which is a procedural language, not really an Object-Oriented (OO) language. I duly looked up objects and methods, properties and inheritance, and encapsulation, but my early attempts to write CI code were plagued by the error message "Call to a member function on a non-object". I saw it so often that I was thinking of having it printed on a t-shirt: it has a mysteriously libertarian, anarchist tone, and I could see myself wearing it at a modern art exhibition.

This is the geek article. It describes the way CodeIgniter actually works, 'under the hood'. If you are new to CI, you may want to skip it. However, sooner or later, you may want to understand why things happen in certain ways—as opposed to just knowing that they do.

Aggregate Services in ServiceMix JBI ESB

by Binildas A. Christudas | November 2007 | BPEL SOA Web Services Java Open Source

Integration is a necessary evil using which we can interconnect systems, applications and services to facilitate seamless information flow within and across Organization boundaries. We have been using technologies like JSP, EJB, JMS, etc. in the Java world for building Enterprise Applications (EA). But if we have to interconnect such applications, we will need Enterprise Application Integration (EAI). Many a times we also use EA technologies and tools to do EAI. This will give a short term solution to our integration problems, which may not scale up when we want to perform integration at Enterprise (Customers, Vendors, Partners, ...) level. Java Business Integration (JBI) is the new specification trying to fill this gap of EAI in the Java world. So next time when you want to integrate, don't write a single line of Java code, instead plug and assemble JBI based integration libraries to control your message flow! Does it looks promising? Believe it or read the article below to get yourself convinced.

In this article by Binildas Christudas, we will look into Integration in general and to JBI and ESB in particular. We will then explain few functionalities usually done by integration components like protocol conversions, content transformations, etc., with some code snippets too.

Creating Accessible Tables in Joomla!

by Joshue O Connor | November 2007 | Joomla! MySQL Content Management Open Source PHP

Tables got a bad review in accessibility circles, because they used to create complex visual layouts. This was due to the limitations in the support for presentational specifications like CSS and using tables for layout was a hack—that worked in the real world—when you wanted to position something in a precise part of the web page.

Tables were designed to present data of all shapes and sizes, and that is really what they should be used for.

This article by Joshue O Connor, shows how to build a simple table using Joomla! and the features contained within the WYSIWYG editors that can make the table more accessible.
