CodeMash 2009 Conference Next Month

I will be attending CodeMash 2009 Conference next month on January 7, 8 and 9. On the first day of the conference, there will be PreCompiler sessions with Code Jam sessions and workshops. The main conference schedule and sessions look very interesting. One thing I noticed about the conference sessions and the speakers is that this is one of those no fluff conferences where the speakers and attendees are IT geeks who have practical knowledge and experience of the topics they are presenting on, which should result in a rewarding experience to the attendees.

Some of the sessions I am planning on attending are listed below:

Day 1:

• Value Stream Mapping Workshop (Host: Mary Poppendieck)
• Kanban 101 (David Laribee)

Day 2:

• Programming in Scala (Speaker: Venkat Subramaniam)
• RIAs with Java, Spring, Hibernate, BlazeDS, and Flex (Speaker: James Ward)
• Dynamic Languages and the JVM (Speaker: Nathaniel Schutta)
• Thrashing (Speaker: Mary Poppendieck)
• Functional Concepts for OOP Developers (Speaker: Bryan Weber)

Day 3:

• Grease, a Parallel Systems Architecture (Speaker: Edward Vielmetti)
• Language Oriented DDD (Speaker: David Laribee)
• Executable Documentation with easyb (Speaker: Andrew Glover)

All-in-all, I am looking forward to meeting other passionate Java, .NET, Python and Ruby developers there and network with regional user group leaders.

If anyone is attending the conference, let me know. We can get together for a cup of coffee or brew.

Application Architecture Trends presentation at Detroit Java User Group meeting

I recently gave a presentation on Application Architecture Trends at Detroit Java User Group meeting on Wednesday evening. The presentation title is "Application Architectures - Where We Have Been, Where We Are Going". The turnout was pretty good (about 20 people) and the presentation went very well. There were lot of great questions and discussion on the items I talked about in the presentation like AOP, Custom Annotations and OSGi. Here is a list of the new technology trends I covered in the presentation:

• Annotations
• Custom Annotations (includes a demo on a Custom Annotation for Object Caching using Spring AOP and EHCache)
• Spring Portfolio
• Spring Core
• Spring AOP
