Significant Productivity Gains with Grails?

geertjan — Thu, 09 Jul 2009 14:20:19 +0000

A colleague asked me today: "Would you argue that using Groovy / Grails can make you significantly more productive for smaller projects as compared to something like JSF? If yes, why?" In response, I created a very small application. At that point, when the small application was complete, I imagined I had shipped it to the customer. I then imagined that, much later, someone else had...

Reuse: Is the Dream Dead?

kirkk — Thu, 09 Jul 2009 05:41:30 +0000

Reuse is software development’s unattainable panacea. The ability to compose systems from reusable elements has long been our achille’s heel. We want reuse so badly, yet our failures are spectacular. Almost all major technology trends of the past 20 years touts reuse as the saving grace. Vendors have sold billions of dollars in software through the broken promise of increased reusability. ...

Scala as the Replacement to the Java Compiler?

jstrachan — Wed, 08 Jul 2009 16:07:52 +0000

Don't get me wrong - I've written tons of Java over the last decade or so & think its been a great evolutionary step from C++ and Smalltalk (lots of other languages have helped too like JavaScript, Ruby, Groovy, Python etc). However I've long wanted a long term replacement to javac. I even created a language to scratch this itch.References Reference: ...

Finally... Maven

xmaniac — Wed, 08 Jul 2009 06:15:15 +0000

I've always been a happy Ant user. Even more so since Ivy has been available. Obviously that puts me in one side of the fence and I've been a very proactive supporter of that kind of project configuration. I must admit that included some rants about Maven here and there. In my biased opinion Maven lacked the flexibility that Ant provided and it was all about dependency management which...

Why are We Embarrassed to Admit That We Don’t Know How to Write Tests?

mhevery — Wed, 08 Jul 2009 05:59:10 +0000

Take your average developer and ask “do you know language/technology X?” None of us will feel any shame in admitting that we do not know X. After all there are so many languages, frameworks and technologies, how could you know them all? But what if X is writing testable code? Somehow we have trouble answering the question “do you know how to write tests?” Everyone says yes, whether or not...

The purpose of this article is to present accurate performance results for the ICEfaces RIA framework, correcting gross errors originally published in the article Performance Report of Server Side RIA Frameworks.

Non-Stop Control of Logging Level

maksymov — Tue, 07 Jul 2009 12:02:22 +0000

Sometimes there is a need to change the logging level in the some modules of an application server. This usually isn't managed easily: the change the logging level means a restart of the server in most cases. This is not always required, but is in most cases.

It is really simple to add clustering support to an Atmosphere's Comet based application, and deploy it inside any Servlet Container supporting Servlet 3.0, Comet or not. You just have to decide which group technology you want to use, thanks to Atmosphere Plug in: Shoal or JGroups! James Sugrue

Patterns in Internal DSL Implementations

debasishg — Tue, 07 Jul 2009 05:25:09 +0000

I have been thinking recently that classifying DSLs as Internal and External is too broadbased considering the multitude of architectural patterns that we come across various implementations. I guess the more interesting implementations are within the internal DSL genre, starting from plain old fluent interfaces mostly popularized by Martin Fowler down to the very sophisticated polymorphic...
