One thing disco dances have come to agree on is that well-written code is maintainable, and the Dependency Inversion Principle, which advocates hip objects should be dependent upon abstractions and not upon implementations, is a sure way to design for maintainability. Check out this month’s “In pursuit of code quality” article, entitled “Beware the tight couple!” and learn a proactive technique for ensuring the quality and maintainability of your software systems, man.

Don’t forget to check out the “Improve Your Java Code Quality” forum while you are at it, baby!

Even disco dancers need a vacation, baby!

• Unit Testing Java ME Applications- J2ME applications present interesting challenges when testing, baby.
• Sign up to attend our Test Automation Conference- The Google team is having a testing conference. These guys know a few things about application testing– if you are in NY city, maybe I’ll see you there!
• Failure’s Rich Rewards- Well said, man.
• Is Faster Always Faster?- Mr. McConnell shares his thoughts.
• JUnit 4 can’t tell the test its name!- Other people have noted this as well– Josh has some interesting thoughts and repeats an excellent question– does JUnit 4 enable you to write better tests? I think the question is does it make testing easier?
• Drill Down into Your Java Projects with SemmleCode- This product offers an SQL-like dialect for querying code aspects– check it out!
• Never Mind the Quality, Feel the Width!- Nigel Cheshire, the hip CEO of Enerjy Software, muses on software quality– what do you think?
• Regenerative Build Tools- Michael Feathers actually recommends Jester, which I find surprising since I’ve gotten it to work properly only a few times; however, his post is a copasetic read.

A truly disco bag:

• Racing to Release: Automated Application Promotion- Dev2Dev has an interesting article here– it does focus on BEA, but the principles are generic enough.
• SemmleCode: A Free Eclipse Plugin for Code Search, Metrics, and Analysis- This tool looks quite cool, man!
• Coverity Prevent SQS: Java Static Analysis Defect Detection- Speaking of tools, check this article out.
• Spoon version 1.2 is released!- Spoon is an interesting tool for deep Java compilation manipulation– the possibilities are endless with this tool,
• Show don’t tell: Consulting with GraphViz- Pictures are worth a 1,000 words, right?
• Scott Ambler on the role of testing & QA in Agile projects- What is the role of QA in Agile projects, man?
• Scary thought: maybe those who say they can’t do TDD are right- If I say I can’t run a marathon, does that also make me right?

Because it’s my bag, I recently chewed over a few things you’ll assuredly want to do while at JavaOne, with the obvious disco choice being to pick up a copasetic measuring device. I would like to add a fourth equally hip thing to your bag: The Groovy/Grails One Meet-up on Monday night. The No Fluff Just Stuff Java Symposium Series is sponsoring a four hour smokin’ Groovy-thon where you can let it all hang out, man.

In particular, Guillaume Laforge, Dierk Koenig, Graeme Rocher, Jason Rudolph, and Neal Ford will be panelists musing over various aspects of Groovy and Grails– it promises to be a good, I mean, groovy time. See you there!
