The Best of the Week (May 9): DevOps Zone

Make sure you didn't miss anything with this list of the Best of the Week in the DevOps Zone (May 9 to May 15). Here they are, in order of popularity:

1. The Pitfalls of Test-Driven Development

A few days ago, David Heinemeier Hansson posted a very negative article on Test-Driven Development(TDD) which generated quite a bit of noise. This prompted Kent Beck to respond with a Facebook post which I found fairly weak because it failed to address most of the points that David made in his blog post.

2. TDD When You Can't Refactor

Maybe Rails apps are too sophisticated in terms of coding constructs to be easily and cheaply test driven. At least compared to Java. Maybe frameworks are harder to TDD too, compared to libraries. Refactoring, in tools like Intellij for Java, is like giving the Mona-Lisa a proper smile with your fingers, hundreds of years after the last brush stroke, and perfectly. Not only that, but Intellij’s local-history undo is perfect too. Don’t like that smile? Hit Ctrl-Z.

3. Java 8 Optional: How to Use it

Java 8 comes with a new Optional type, similar to what is available in other languages. This post will go over how this new type is meant to be used, namely what is it's main use case.

4. Configuring Sonar in Ubuntu and Analyzing Project

Static code analyzer now become very common and useful while teams will be working specially using RAD. As to meet close deadlines and sprint dates developers usually get out of the right path and use some narrow tactics to accomplish some task.

5. Effective Puppet Module Management in Vagrant

I still remember my first early forays into using vagrant and puppet together to provision local development environments. Everything was easy accept figuring out a proper way to bundle puppet modules with a project. Basically it was a three step phase of discovery.
