"Ajax [1] is changing web applications, giving them a responsiveness that’s unheard of beyond the desktop. But behind all the hype, there’s not much to Ajax — (X)HTML [2], JavaScript [3], and XML [4] are nothing new, and in this tutorial, I’ll show you how to simplify the process of adding Ajax to your application even further with the help of jQuery, a popular JavaScript library."

Sometimes, it seems that the world is all about man vs. technology, and one has to lose. This seems to be the question raised about AJAX; from the general challenges of AJAX, including cost and expertise needed, to its security issues, will the technological good prevail or will we humans be seeking an alternative?

"Ajax is surprisingly easy to use with the Arc language. This article shows how to implement Ajax-based autocompletion and dynamic page updates using the script.aculo.us and Prototype JavaScript frameworks. These frameworks allow Ajax applications to be implemented with just a few lines of additional code. The hard work is done by the script.aculo.us and Prototype libraries.

Security researchers have warned that a new class of vulnerabilities dubbed "clickjacking" puts users of every major browser at risk from attack.

It's not always true that the neatest, most advanced technology ends up winning most of the market share. There are other reasons which get in the way. Sometimes, the less advanced solutions end up winning - and evolve in order to become more solid and established.

Web application development has been revolutionized by Ajax. What was once a new and flashy technology is now becoming ubiquitous. End users are coming to expect that certain interactions with a Web application will be done "with no refresh," in other words, using Ajax. The ubiquity of Ajax for users has not yet translated to client-side technologies.

Tibco Software Monday introduced a tool aimed at easing the development of enterprise mashups. The new Tibco PageBus, which the company describes as an open-source message bus, creates a "publish and subscribe" model that can help users more easily tie together Web services and Asynchronous JavaScript + XML (AJAX) components to create mashup applications.

Security researchers will demonstrate a malicious "rootkit" program they've written for Google's Android phone next month at the Defcon hacking conference in Las Vegas.

Maintaining a complex web application that uses a lot of Javascript for client-side, "AJAX"-style interactivity is rather difficult. The clumsiness of the Javascript language itself, as well as the various tricks needed to make an application work consistently across multiple browsers, all of which must be wrapped up inside HTML, makes for a jumble of issues for the application developer.
