Chicago, IL May 13, 2008 -- Pathfinder, a leading software development and user experience design firm, today announced the publication of "Ajax overhaul, Part 2: Retrofit existing sites with jQuery, Ajax, tooltips, and lightboxes."

Written by Pathfinder's Brian Dillard and published by IBM developerWorks, this piece marks the second installment in an ongoing series. Each edition of "Ajax overhaul" shows how to improve the user experience of legacy web applications using Ajax programming techniques. The tutorials feature "before" and "after" source code of a fictitious shopping application, allowing readers to see both versions in action and learn by example.

"In my examples, I show how open-source Ajax libraries can solve old usability problems in addition to providing new features. I chose to focus on jQuery, a powerful Ajax toolkit that makes it easy to design Ajax feature using progressive enhancement," said Dillard. "This approach guarantees that web applications stay accessible to all sorts of users, from those with physical disabilities to those using older browsers or cell phones."

Ajax is a technology that transforms slow, static websites into dynamic, responsive applications that feel more like traditional desktop software. Ajax is a technology for implementing Rich Internet Applications (RIA). RIAs can dramatically enhance user experience while boosting performance and productivity.

At the same time, Ajax can enable the migration of traditional client server applications that were previously too complex to effectively deploy on the web, providing an easier and more cost effective option for support and maintenance.

IBM developerWorks is a premier technical resource for software developers, providing a wide range of tools, code, and education on a wide array of web-based technologies.

Brian Dillard is an Ajax expert who builds rich Internet applications for a variety of Pathfinder clients. He participates in open-source projects and is a regular contributor to the Agile Ajax blog. He is also the project lead on Really Simple History, a popular open-source Ajax history and bookmarking library.
