Source: developerWorks : Open source : Technical library Whether looking for the nearest coffee shop on a GPS-enabled smartphone, nearby friends via a social-networking site, or all trucks within the city delivering a certain product, more and more people and businesses are using location-aware search services. Creating such services has often been the domain of expensive proprietary solutions and geospatial experts. Recently, however, the popular open source search library, Apache Lucene, and the powerful Lucene-powered search server, Apache Solr, have added spatial capabilities. Lucene and Solr committer Grant Ingersoll walks you through the basics of spatial search and shows you how to leverage its capabilities to power your next location-aware application.

Source: developerWorks : Open source : Technical library ZK, an open source Asynchronous JavaScript + XML (Ajax) framework
written in Java code, lets you write a Web 2.0-enabled, rich Internet
application without writing a single line of JavaScript code. Typical Ajax
frameworks like Dojo have JavaScript libraries that expose certain API's for
making "Ajaxified" calls. ZK, on the other hand, uses a meta-definition based
on XML to define the user interface. Translation to HTML code then occurs when
this page is requested by the client. This article introduces you to ZK and
gives you a real-world example of its use running on Apache Tomcat and
connecting to a MySQL database.
