RSS (Rich Site Summary, RDF Site Summary, or Really Simple Syndication) has been around since the mid-1990s. Over the years, several variants of the RSS format have popped up and several claims have been made about its ownership. Despite these differences, RSS never ceased to serve its usefulness in distributing Web content from one Web site to many others. The popularity of RSS gave way to the growth of a new class of Web software called the feed reader, also known as the feed aggregator. Although there are several commercially available feed aggregators, it's easy to develop your own feed aggregator, which you can integrate with your Web applications. You'll appreciate this article's fully functional PHP code snippets, demonstrating the use of PHP-based server-side functions to develop a customizable RSS feed aggregator. In addition, you'll reap instant benefits from using the fully functional RSS feed aggregator code, which you can download from this article.
XAML stands for eXtensible Application Markup Language and was created by Microsoft. It is currently the primary mechanism for declaratively creating the user interface in a Windows Presentation Foundation (WPF) application. WPF is part of the .NET 3.0 framework. Why discuss these very technical things in a design blog post? The answer is simple: because XAML is designed for designers. It has other uses of course, but one of its main tenets is that XAML enables the separation of UI and logic (code). That is a very powerful concept! In this and future posts, I will explain how a few of us at Autodesk are using XAML in our design process as a way to enable design refinement during the Development phase.
