We’ve now done another big internal clean up of this code, to make it easier to read and easier to understand. As previous mentioned all actions (insert, update, delete etc) are now placed into a thread safe propagation queue. The ...

Rebooting ALM, Part II: Power

software-development-2-logo

This is the 2nd part in the Rebooting ALM series. Check out the first part “Evolution“, to see how we got here. (See what I did?). The first tool, I think, that started the ALM tool chain, was source control. There were compilers, and some IDEs, but source control systems were solutions for team-work. If you think about it, the ...

This is the first in a series about Rebooting ALM. I’m going to present this next at Agile Slovenia in a week, don’t miss it.

javafx-logo

The last week has seen some discussion on the web related to the future of JavaFX. Many people got the impression that JavaFX will be put on ice by Oracle. This was primarily caused by a blog post written by Shai Almog (Codename One) called “Should Oracle Spring Clean JavaFX”. It was  “inspired” by a blog that I had written a little bit ...

OpenMap Tutorial 3 – Build a basic map application using the MapHandler – Part 2

java-logo

1. Introduction In the previous tutorial we saw how the MapHandler can wire up various components together (more specifically classes that derive from MapHandlerChild). We saw how we could do this programmatically, but there is also another way, declaratively, using the openmap.properties. The sample OpenMap application is configured with an openmap.properties file. The contents of this properties file specify which ...
