Featured Presentation: Ehcache


Ehcache is an open source, standards-based cache used in a wide array of applications to boost performance, offload the database and simplify scalability. Ehcache is robust and in use in thousands of mission-critical applications. It is the most widely used Java-based cache.

With the release of 2.0, you can use Ehcache to:

  1. Snap into Hibernate, OpenJPA, Eclipselink and offload the database 80% or cache direct JDBC responses from the database by hand
  2. Build the highest performance into your application using write-behind, ReadOnly views, NonStop caches, WAN replication, and more of the new enterprise-class features in the framework
  3. Monitor and tune your caches in production with JMX or your favorite monitoring tool like Nagios

You will learn:

  1. How to snap Ehcache into the latest Hibernate
  2. The differences between Ehcache, expensive data grids from companies like Oracle and IBM, and Memcached
  3. About the new Ehcache Monitor and how to use it
  4. About the detailed roadmap of Ehcache 2 through the rest of this year.

Basic Concepts: HTML5 Primer

Frederic Jean’s slide deck can be found here: http://djug-html5.heroku.com/


HTML5 is already changing how web applications are written and delivered. It introduces new capabilities to the browser environment and simplifies some frequent tasks that face web developers. The need to continue supporting older browsers introduces some challenges in fully adopting HTML5.

We will discuss some of the new HTML tags, CSS rules and JavaScript API introduced by HTML5, what is currently supported by modern browsers and discuss some strategies on how to deal with older browsers.

About the Speaker:

Frederic Jean brings over 13 years of experience developing and supporting applications on the web. His current focus is on delivering online video to browsers and other devices using both native and HTML based user interfaces.
