2015-04-20T08:39:00.000+02:00

Let Genetic Algorithms (more specific: Genetic Programmic) do the work for you. Here you will find more information about that and how to obtain the source code (of course you can try for yourself). Another article covers some general overview of RobocodeJGAP (written in German). Have fun creating robots in Java with RobocodeJGAP and Genetic Algorithms! Try to go for the higher ranks on the

LINQ is great but is 20 years too late

2007-09-13T12:40:00.000+02:00

LINQ is the Language-Integrated Query. Microsoft has the LINQ project running for integrating database queries into C#. Sort of looks like this (example taken from DevelopMentor):IEnumerable < Product > prodQuery = from p in db.Products where p.Category.CategoryName == "Beverages" select p;Sort of this is what I'm missing for long in Java!!!Before getting to

URLEncoder/URLDecoder way too slow

2007-06-21T15:47:00.000+02:00

As I recently found out by trying, the methods encode in java.net.URLEncoder and decode in java.net.URLDecoder are way too slow.Following an advice, I replaced these calls with encode and decode from class org.apache.commons.codec.net.URLCodec which is part of the Apache Commons Codec library.Running the same application with Java's built in coding logic and another time with Apache's, showed me

Sourceforge CVS is stuck with WinCVS

2007-01-14T11:56:00.000+01:00

For several weeks now I noticed great difficulties when trying to access the sourceforge CVS of my project with WinCVS (any version!). Don't get me wrong, it worked for years! But since a while I even get a long delay on WinCVS startup. Not to mention the really long time it takes checking in something.OK, it could be that my system's configuration is not playing together with sf's CVS. But why,

Faster than light... this time not with Java

2006-05-25T14:42:00.000+02:00

Isn't that awesome! Light can predict the way it will take (or, to adapt this statement to the new findings: ... it had taken in future).Quantum physics has not been mentioned in the article but it is definitively sort of issue QP will have to cope with.This is not related to Java in any way but it's so gorgeous that it's worth an entry :-)

Common Annotations for Java (JSR 250) shamefully approved

2006-04-19T09:19:00.000+02:00

After several protests of mine to avoid the finalization of JSR 250 (Common Annotations for Java), now the Executive Commitee has shamefully approved that JSR.Thanx Doug Lea for adding a comment to his vote the first time I can remember. He wrote: "Underwhelming but innocuous". Then, Doug, you better voted with "No", please. That would have raised your reputation a lot...Anyone, please read the

Anybody using JUnit's ExceptionTestCase ?

2006-01-10T13:01:00.000+01:00

To write a unit test that expects an exception of a particular type to be thrown is possible by using JUnit's class junit.framework.ExceptionTestCase. However the usage of this class (that inherits from junti.framework.TestCase) is ugly (details such as import statements omitted):1. Test classpublic void MyTestCase extends ExceptionTestCase { public void testXYZ throws Exception { MyClass

The deadline

2005-12-27T16:17:00.000+01:00

Motivated by a current project with late hours of work, this text resulted. In this project, there was a deadline until the productivity start had to happen. Of course, this deadline was given by higher instances not knowing about the work done by the divisions below them (development, operating department).Most of you should know this scenario. Many of you, I guess, have read the excellent book

Console Outputs in Unit Test

2005-11-14T09:59:00.000+01:00

During the review of several unit tests in different projects, there are usually tests containing output statements (such as System.out.println or file output). My initial opinion to outputs in tests, especially to console outputs, is that they should be avoided in any case.When thinking further, it seems to me that gathering data in a file could be legitimate for some situations. But console
