Follow Anyone, an app that explores some of the fun and interesting visual possibilities of extruding native iOS fonts on the iPad to create colorized, 3D text, is now available through iTunes. I also have a separate support site and blog for the app. The app is currently free and will remain so for a very short time.

This is formerly the home site of XQEngine, an open-source, XQuery-based, embedded Java component for querying XML documents. XQEngine is now hosted at SourceForge. I'm not currently maintaining XQEngine but may return to it in future.

Other Stuff ...

• I've finished working on upgrades to pocket BLU, a Deluxe Digital Studios iPhone app that lets you use your phone as a remote control for Blu-ray DVD players.

• I'm the editor of a book on XQuery, XQuery from the Experts, published by Addison-Wesley. The book is written by members of the W3C's Query working group, including such well-known names in the XQuery world as Don Chamberlin, Jonathan Robie, Michael Kay, and all the other stellar participants listed on the cover below. The book is available (naturally) at Amazon.

  Here's Don Chamberlin's superlative Chapter Two, Influences on the Design of XQuery. Don was the co-developer of SQL.
  
  

• Here's a presentation on Implementing the XQuery grammar I delivered at Extreme Markup 2002 in Montreal. It's an introductory tutorial on using the JavaCC and JJTree parser-generator tools to implement grammars such as XPath and XQuery.

• Here's an introductory article on XQuery that I wrote for IBM's developerWorks website.
