Simply put, Jiggy is the easiest way to create applications for the iPhone (or iPod Touch). With just Jiggy and a browser, you'll be able to write an awesome iPhone application in a matter of minutes. JiggyApps run natively on the iPhone, so there is no messing around with HTML and the limitations of Mobile Safari. At the same time, you don't need a compiler or even a Mac, because JiggyApps are written in JavaScript.\n

CNET Networks owns a global network of popular web sites with a combined average daily page views of over 86.3 million. To keep our sites running smoothly, we frequently have to monitor and trouble shoot our Java applications. In additional to the tools and utilities that come with Java, we also use a few free tools to get the job done.\n

Apache Maven is a powerful and extensible tool for managing software build and project information. When used effectively, it can greatly simplify a project's build, reduce maintenance, improve automation and make producing consistent releases simple. However, it is also easy to encounter common pit falls that lead to unwieldly or problematic Maven set-ups.\n

What are the core requirements for a set of team collaboration tools? Looking at how ASF project communities collaborate online, we have identified four core drivers that help these projects succeed. We will show how the collaboration tools used by the ASF can allow any project team to move from an "ask around the office" collaboration model to our efficient "distributed self service information" model, while focusing on those core drivers to avoid being distracted by the tools themselves.\n

Apache Tika is an extensible content analysis toolkit designed for detecting and extracting metadata and structured text content from a large number of document formats. It represents an higher level layer over existing parser libraries. World-class content management systems, and most of all enterprise document management focused ones, always have to face the challenge of detecting, extracting and indexing as more various media content types as possible.\n

In this session you'll be introduced to Wicket's programming model, and we'll quickly go from simple components, form processing and providing feedback to integrating with Spring and Guice, securing, testing and deploying your application. A lot of ground to cover but the best way to learn everything you wanted to know about Wicket.\n

One of the main new features in Apache 2.2 is the enhancement of the proxy module, allowing Apache to proxy not only HTTP as before, but also AJP. Coupled with the dynamic load balancing capability also new in 2.2, see why Apache is now an even more capable reverse proxy, and see why mod_jk may no longer be required. Included are helpful real-world hints in configuration for high-availability failover environments.\n

Apache Solr is an HTTP based enterprise search server built on top of the Lucene Java search library. In this session we will look at Solr's internal Java APIs and discuss how to write various types of plugins for customizing it's behavior — as well as some real world examples of "When" and "Why" it makes sense to do so.\n

With the massive rise in both structured and unstructured data comes the need to better understand what is in the data. Machine Learning algorithms are often designed to make sense of large volumes of data with minimal human input. In this talk, we cover some of the basic algorithms of machine learning (without all the gory math) and show how the new Apache Mahout project is attempting to solve these problems in a scalable way by utilizing Hadoop.\n

I will discuss the traps, bottlenecks, and even some big wins we have encountered along the way using LAMP. From the small scale to using custom proxies running on Apache with worker and mod_php. We have done many interesting things to give our readers (and our content team) a good experience when using our web site.\n

How are the Lucene technologies being used in the real world? This fast-paced talk presents many applications leveraging lucene.apache.org technologies, including Java Lucene, Solr, Nutch, and Mahout. We'll see how Lucene powers more library searches, sells more shoes, rents more videos, books more hotels, than high priced closed-source alternatives.\n

I’ve developed a method of integrating Google Analytics which allows the user/client to regain control over the loading and execution while not blocking other JavaScript code on the page from executing. This method requires either YUI or jQuery to be present but can be adapted to work with other JavaScript libraries.\n
