The Architecture Spike Kata

Johannes Brodwal — Thu, 22 Dec 2011 08:28:09 -0500

Do you know how to apply coding practices the technology stack that you use on a daily basis? Do you know how the technology stack works? For many programmers, it’s easy enough to use test-driven development with a trivial example, but it can be very hard to know how to apply it to the problems you face every day in your job.

Can we replace requirement specification with better understanding?

Johannes Brodwal — Fri, 23 Sep 2011 12:39:30 -0400

On larger projects, I’ve always ended up resorting to writing down a lot of detailed specifications, many of which are wrong, irrelevant or we might not be ready to answer them yet. On small projects, the dialogue between the customer and the developers can flow easy, and good things happen.

The quick analysis

Developer: … so we’re going to complete the current task tomorrow or the day after. Could we discuss what to do next before you’re off to your next meeting?

What will Java 7 mean for you?

Johannes Brodwal — Sun, 07 Aug 2011 18:35:38 -0400

Oracle released Java 7 on July 28, 2011. This is nearly 5 years after the release of Java 6 in December 2006. The release received a lot of bad press, both because it is very meager on features, and because it shipped with a severe bug. Nevertheless, once the most serious bugs have been fixed, you might think about starting to use Java 7. What will this mean?

Video: No-red refactoring

Johannes Brodwal — Fri, 05 Nov 2010 03:00:35 -0400

The more I code, the more I’ve learned to appreciate keeping the code clean even during complex refactorings. By “clean”, I mean that the code always compiles and the test always run.

I often find myself in a situation where I have a method call that’s starting to accumulate parameters. Something like this:

Cross-cutting code, the homemade way

Johannes Brodwal — Tue, 26 Oct 2010 09:00:24 -0400

I though I’d do something different this time. Instead of describing something technical, I have recorded a five minute video that shows a very neat trick in Java: How to create a bit of code that wraps existing method calls to an object with any behavior you may desire.

This is nothing new, but I’ve noticed that not many developers know how to use it, so I hope this video may be useful:

Eclipse telepathy: Your IDE can guess what you want

Johannes Brodwal — Thu, 14 Oct 2010 06:00:37 -0400

Ctrl-1 is the magic “do what I think” button in Eclipse. Whenever I press it, Eclipse seems to come up with something that’s helpful in the current context. In this blog post, I illustrate 10 things that Eclipse hide under the ctrl-1 keypress. This is a follow up on my post on Eclipse stenography.

How pair programming and test-driven development looks in real life

Johannes Brodwal — Thu, 30 Sep 2010 11:00:29 -0400

Pair programming and test-driven development are some of the practices that are most often talked about and least often actually understood. So I’ve decided to undertake the task to teach myself to program a simple, yet realistic problem with a pair programming partner. The goal is to create an entertaining and realistic performance that portrays what it feels like to work like this.
