Retrospective using Jimmy Cards
March 30, 2013 – 2:13 pm
I had taken on to facilitate a retrospective for my colleagues’ team. They wanted a different retrospective than the usual. So we borrowed Crisp’s office and used Jimmy Cards!
The group was around 15 persons from two teams. They all knew each other well which I believe is crucial as the questions on the cards can be challenging.
In this post I’ll give you the recipe which Jimmy and I came up with for this particular retrospective.
Why do we never get the time to work on system architecture?
November 18, 2012 – 4:28 pm
Have not all of us been in a spot where we feel an urgent need to fix some quality such as performance or availability, which takes a change in the architecture for effect? And yet we are pushed to work on new features instead?
There is a chasm between the tech side and business side that has to be bridged before a sound dialogue about system architecture can take place.
Canned Wicket Examples Updated to Wicket 6
October 7, 2012 – 2:47 pm
Today I decided to update my canned wicket test examples to the latest version of Wicket.
I still think Wicket is a really nice web framework for the following reasons, primarly.
- Hot deploy from the Maven archetype. The quick start setup offered from the Wicket site gives you “change-and-reload” out of the box.
- Unit testing framework built in. You test the logic of the web application without resorting to click simulation.
- HTML separation. Allows you to work in a tight loop with an interaction designer that can use any HTML editor.
- No need for JavaScript. Well, for the basic stuff at least. The examples here all use AJAX.
Using CloudBees for teaching XP practices
September 10, 2012 – 12:00 am by Per Lundholm and Henrik Kniberg
We are doing a course called “Certified Scrum Developer”. We are of course proud of being one of the few eligible by the Scrum Alliance to hold such a course. But what matters most to us is teaching some modern development practices. The certificate bit is more of a bonus.
Crisp had recently its fifth installment of a code camp, the “Crisp Hack Summit”. It is an occasion for everyone at Crisp to go bananas on some project of their liking. We took the chance to work on the technical platform for the CSD course. We know from experience that you can loose a lot of valuable lecture time if the technical environment decides to hassle. Murphy, will you be there?
How to hire a real star developer
August 31, 2012 – 2:59 pm
What makes the difference between a star developer and a day coder? First of all, with a star developer I don’t mean star as in ”famous”, rather as in ”elite”. And, a day coder is OK to be, no disrespect here. We need you as much as we need the elite.
My point here is that if you wish to hire a real star, you need to know what to look for.
Window, Scene and Node coordinates in JavaFX
August 29, 2012 – 12:26 pm
Here is an illustration on how the coordinate systems of the screen and JavaFX objects relate to each other. It is a great thing with JavaFX that you seldom bother about screen coordinates. Instead you rely on layout managers to position your nodes on screen. A node has its own coordinate system, should you like to do some positioning, e.g. in a game.

An Analog Clock in JavaFX
August 9, 2012 – 9:10 pm
JavaFX is great fun but there are so many ways of doing things. You can use FXML, you can use images to build things piecewise or you can write code for a live, scalable design. The latter is the case here where I show how I created an analog clock using Java code.
The clock is designed with the clockwork in a separate class and the face in another.
This text shows some example JavaFX code in Java slightly above introductory level. You should have your development set up and done at least a first program.
