ExpressionEngine: Creating a Photo Gallery

by Leonard Murphy | September 2008 | MySQL Content Management PHP

ExpressionEngine comes with a built-in photo gallery module included as part of the purchase fee. With the prevalence of digital cameras, having a place to upload and share photos on your website is a great feature of ExpressionEngine. In this article by Leonard Murphy we will:

  • Install the photo gallery module
  • Design our photo gallery to fit in with the design of the rest of our site
  • Make it easy to upload new photos, add comments and descriptions, and otherwise create a very functional gallery

On our website, we can have multiple photo galleries independent of each other (the photos are in a different folder; the gallery has a different URL) or we can have one gallery for all our photos, using categories to distinguish groups of related photos.
For the purposes of this article we are going to create only one photo gallery, but if desired the same principles can be followed again to create multiple galleries.
To keep our photo gallery visually interesting, we will be straying just slightly from our toast website theme, and will not be using our photo gallery to display slices of toast.
Let's get started!

Oracle Web Services Manager: Authentication and Authorization

by Sitaraman Lakshminarayanan | August 2008 | BPEL SOA Web Services Oracle

The first step in protecting web services is to authenticate and authorize the web service requests. Authentication in web services is the process of verifying that the user has valid credentials to access the web services and authorization is the process of validating that the authenticated user has appropriate privileges to access the web services. Besides restricting access to users with valid credentials and proper privileges, Oracle WSM can track who accessed which service and when—to provide detailed audit trails. In this article, Sitaraman Lakshminarayanan explores how Oracle Web Services Manager can be leveraged to authenticate and authorize the web services requests.

Application Development in Visual C++ - The Tetris Application

by Stefan Björnander | August 2008 | .NET Microsoft

Tetris is a classic game. In this article by Stefan Björnander, we will develop a version very similar to the original version. Seven figures of different shapes and colors fall down and the player's job is to move and rotate them into positions so that as many rows as possible are completely filled. When a row is filled, it disappears. Every removed row gives one point.
