Comparing MVC Frameworks?

I saw a question on one of LinkedIn groups asking for a comparison of MVC frameworks. Obvious reaction is to point to Matt Raible's presentation from 2007 on this topic. Thinking further brings up an "It Depends" moment. Now days it is not enough to just use "best" MVC framework.

• Is this a green field project, i.e. do you have any legacy code to integrate?
• What type of application is this going to be?
• Is there need for wizards with suspend/restart functionality?
  
• What are you using for persistence?
• Do you have need for DI container?
• Is there a need for "flashy" desktop feel to the application?
• What is experience level of developers who will develop this application?
  

Those and other questions must be considered before making a decision on presentation framework. UI is only one, albeit very important, part of the system architecture. Care must be taken to pick a UI technology that compliments and plays nice with other pieces of overall system.

Before jumping in bed with a framework make sure that development staff is comfortable and understands underlying technology, i.e. does not have to be retrained. Make sure that picked technology fits with a business direction/objectives/strategy few years in a future. Don't get caught up in a short term trends or you will suffer pains of complete rewrite when business focus changes.

Change of course at SpringSource

Glad to see an announcement from Rod. Honestly, what took so long?

We are amending our maintenance policy in the light of community feedback. We will make regular binary releases from the Spring trunk available to the community, with no 3 month window. For each version of Spring, community releases will be available while it remains the trunk or until the next version is stable.

Once we have published a release candidate for a new version of a project, we will typically not release further tags or binary builds of earlier versions of the project to the open source community. Such releases will be available for three years to SpringSource Enterprise customers.

This is the type of a policy that I would be completely comfortable with. Initial version seemed a little out of character and rushed. Call me a "Spring Fan Boy" but I am mighty happy with the news today.

Cloud Computing Conference

What is Cloud Computing? It depends on who you speak to. I don't have an answer. I like the idea and would like to learn more about it. If you are like me, my employer Chariot Solutions is sponsoring a conference on Cloud Computing on Friday, October 17th at the Penn State Great Valley campus.

We have some big names attending:

• Jeff Barr of Amazon.com speaking about Amazon's EC2 and S3 Cloud Computing platform
• Joe Gregorio and Johnathan Rochelle of Google, talking about Google App Engine and Google Spreadsheets
• Justin McCarthy and Britt Crawford of Cafe Press, the developers of HiveDB, a cloud-capable database platform
• Prasaad Chakka of Facebook, speaking about data warehousing in the cloud with Hive
• Chris Richardson, author of "POJOs in Action" and developer of CloudTools, a mechanism for deploying Java and Groovy applications in the cloud
• Ezra Zygmuntowicz of Engine Yard, a Rubyist, developer of MERB (a high performance alternative to Ruby on Rails) and author of Vertebra, a cloud computing platform

There are several more sessions, including an hour-long panel talk on using Amazon and other cloud platforms with local experts Toby DiPasquale, Chis Cera, and Andrew Kortina.

Maybe I'll see you there.
