Today a colleague of mine and I conducted a Hibernate training for a medium sized Dutch software house. My part of the training was helping with the hands-on exercises and giving a presentation on the basics of HQL , the Criteria API and association mappings.
Since I’m not using Hibernate on the current project (we use […]

For the project we’re working on we can not use Java 5; customer demands. This means we can’t use the enum type to group constants. A colleague of mine pointed out that nested interfaces can provide very similar results:

public interface Constants{
public interface A{
String CONSTANT_ONE = “asdfasdf’;
String CONSTANT_TWO = “asdfasdf’;
}
public interface B{
String CONSTANT_ONE = “asdfasdf’;
String CONSTANT_TWO […]

I found a nice post about why geeks make good fathers. This of coarse includes Lego ™, video games and gadgets..! And yes I fully agree with the write-up, since this is what I do AND this is what my own father did/does!

RadRails is an integrated development environment for the Ruby on Rails framework. The goal of this project is to provide Rails developers with […]

Today the serverside featured a post with the eye-catching title ‘Java: Dead Like COBOL, Not Like Elvis?‘

Gruff is a charting library for Ruby which can be used alone or with Ruby on Rails. I tried using it a couple of times, but couldn’t get it to work. The error was non-informative at best:

uninitialized constant Gruff (NameError)
NoMemmoryError

After going over the following steps:
1. build and installed ruby 1.8.4 from source
2. downloaded ruby-zlib-0.6.0 and […]

Tonight I attended the Ruby workshop presented by two of my colleagues. It was a bit more advanced than generating Rails stuff and focussed on interesting Ruby features like:

mixins
closures
operator overloading
usage of the missing method method
breakpoints
unit and functional testing
a bit of ajax (got to have it in your Ruby and Rails examples)
migrations

The presentation was code heavy […]

Browser requirements for the project I’m working on include MS IE >= 5. To bad, but true. Since this implies that we test the developed application in IE I previously used VMWare (good stuff!) to do this.
But having different versions of IE in windows proved to be difficult and I ended up with multiple VMWare […]

In a previous post I mentioned ‘rumors’ about Oracle buying open source projects. Yesterday one of the rumors was confirmed, Oracle bought Sleepycat! Nothing concrete about JBoss and Zend yet….

Today I started tutoring my sister…. at the end of the course she needs to be capable of writing a search engine for one of the subjects in her CKI Bachelor/Masters; in Java.
