ASP.NET MVC Framework

by Vivek Thakur | November 2008 | .NET Architecture & Analysis Microsoft

These days, Model View Controller (MVC) is a buzzword in the ASP.NET community, thanks to the upcoming ASP.NET MVC Framework that Microsoft is expected to launch soon. The Framework allows easier adoption of the different MVC patterns in our web applications.In this article by Vivek Thakur, we discuss ASP.NET MVC Framework in detail with the help of a Sample Project. We also take a glance at Unit Testing with reference to ASP.NET MVC Framework.

The ASP.NET MVC framework was released by Microsoft as an alternative approach to webforms when creating ASP.NET based web applications. The ASP.NET MVC framework is not a replacement or upgrade of webforms, but merely another way of programming your web applications so that we can get the benefits of an MVC design with much less effort.

Obtaining Alfresco Web Content Management (WCM)

by Jeff Potts | November 2008 | Content Management Open Source

People have been using Alfresco to manage web content since the early days of the product. In 2007, Alfresco released its formal web content management functionality that added features most people expect when they think of a Web Content Management (WCM) offering, including templating, site preview, snapshots, virtualization, and deployment. WCM is a specialized subset of the larger Enterprise Content Management (ECM) umbrella that is focused specifically on authoring, managing, and publishing files used to produce a website.

In this article by Jeff Potts, we will discuss how to create a web project and define web forms using XML Schema to allow non-technical users to create content.

Migration from Apache to Lighttpd

by Andre Bogus | November 2008 | Linux Servers Open Source

In this article by Andre Bogus, we will be focusing on migrating from Apache to Lighttpd web server. Lighttpd is the perfect solution for every server that is suffering load problems, as it has a small memory footprint compared to other web-servers, effective management of the cpu-load, and advanced feature set, such as FastCGI, SCGI, Auth, Output-Compression, URL-Rewriting, and many more. Apache is still the most common web server used today, so while we wait for Lighttpd's world domination, the migration from this server warrants its own article. As this article is on Lighttpd and not on Apache, it assumes some knowledge of the Apache configuration. If anything is unclear, the Apache documentation at will be of help.

Resource-Oriented Clients with REST Principles

by Samisa Abeysinghe | November 2008 | Architecture & Analysis MySQL PHP Web Development

Resource-Oriented clients are client programs that consume services designed in accordance with the REST architectural principles. The key REST principles include:

  • The concept of resource (for example, a document is a resource)
  • Every resource given a unique ID (for example, document URL)
  • Resources can be related (for example, One document linking to another)
  • Use of standard (HTTP, HTML, XML)
  • Resources can have multiple forms (for example, status of a document, updated, validated, deleted)
  • Communicate in a stateless fashion using HTTP (for example, subsequent requests not related to each other)

In this article by Samisa Abeysinghe, we will study how we can implement clients to consume those services. We will use a real-world example, the simplified library system, to learn from scratch how to design clients with REST principles in mind.

Using JavaScript Effects with Joomla!

by | November 2008 | Joomla! MySQL Content Management Open Source PHP

Although Joomla! has all of the basic content management tools you need to build a website, it is also designed to run custom-built extensions written in PHP. This article steps through working examples of PHP code written to work seamlessly in Joomla!. Modern websites use JavaScript-driven effects to aid navigation, reduce on-screen clutter, and provide interactive features that are not possible with static HTML.

Joomla! has several built-in elements that you can use without writing a single line of JavaScript. The MooTools framework powers many elements seen throughout the Joomla! backend UI; these can be reused in both the frontend and the backend of your Joomla! component. In this article by Joseph L. LeBlanc, we will learn to use JavaScript effects through these topics:

  • Customizing Google Maps

Visual SourceSafe:Creating a Service-Oriented Application

by Alexandru Serban | October 2008 | .NET Microsoft

In this article by Alexandru Serban, let's take a more realistic software development scenario. What I am going to build is a room-reservation system for the newly launched Orbital Hotel. As you well know, this is the very first space building, after the International Space Station, used for tourism, allowing people to enjoy a view of our blue planet and stars from their private rooms. OK, OK, the Orbital Hotel doesn't yet exist, but when it does, it must have a room reservation system anyway. Who knows, it might be this one.

Business Blogging On The Up - Technorati State of the Blogosphere 2008

by Paul Thewlis | October 2008 | MySQL Content Management Open Source PHP WordPress

"Technorati recently published its annual report, State of the Blogosphere 2008. As usual, it makes interesting reading, especially for those of us interested in business blogging.

The report shows that Technorati has indexed 133 million blogs since 2002. 1.5 million blogs have been updated in the last 7 days and 7.4 million in the last 120 days. These figures support my argument in the first chapter of my book, WordPress For Business Bloggers, that business bloggers should not be put off by the total number of blogs out there because, in fact, only a small proportion are active."

Chatroom Application using DWR Java Framework

by Sami Salkosuo | October 2008 | AJAX Java Open Source Web Development

DWR (Direct Web Remoting), is an Open Source Java framework, licensed under commercial-friendly Apache Software License v2 for building AJAX applications. DWR's main idea is to hide AJAX implementation details such as XMLHttpRequest from developers. Developers can concentrate on developing the application and business objects and leave AJAX details behind the scenes where they belong.

In this article by Sami Salkosuo, we discuss a Chatroom application which demonstrates the use of DWR. The Chatroom sample application is a very typical multi-user chatroom. The functionalities of this sample include a list of online users, automatic refresh of chat text, and the ability to send messages to the chat room.

Comparing Cursor and Set Approaches in Processing Relational Data

by Djoni Darmawikarta | October 2008 | MySQL PHP

MySQL introduced cursor in its release 5. You create a cursor to define a set of rows from one or more table that you want to access row-by-row sequentially. If your need is really to access the rows one at a time then use cursor. But a lot of data processing is actually set processing, and set processing is what relational database is best for.

This article by Djoni Darmawikarta compares cursor approach and set approach using various examples.

Change Control for Personal Projects - Subversion Style

by Gurudutt Talgery | October 2008 | Open Source

Change is a constant companion in our daily routine. Most of what we do is changing (transforming) one work product into another or revising or updating it. We might be transforming requirements into design, design into a prototype, client brief into a story board, idea into a concept document, creating versions of a banner ad, or updating a project plan to reflect progress; the list goes on. In this introductory article by Gurudutt Talgery we will see how we can bring a change management discipline to our work products or personal – not just software – projects with two simple tools on Linux: Subversion and a GUI front-end called eSvn.
