I’ve seen many cool effects created with Three JS for quite some time and I always wanted to experiment with it myself but just didn’t find the time… until now! I like to share some stuff I made with ThreeJS on this page. In this article I’ll show them to you. I’ll add more demo’s here in the future as I go along…Lees “First tries with Three.JS” verder
Android multitouch gesture detectors
Android has a ScaleGestureDetector since API level 8 (Android 2.2). From this point on the first Android devices with multitouch screens appeared. This was great, and the ScaleGestureDetector too ofcourse.
What’s a mistery to me however, is why this is the only multitouch gesture detector that is in the API! Why isn’t there something like a RotateGestureDetector to find out rotations between two (or more) fingers… Is it one of the issues in the patent war between Apple and Google? I don’t know, but I want to be able to use it anyway… so I built this small extendable framework and I’ll explain in this article how you can use it in your Android apps! Now hope I won’t get sued for building the obvious :shock:! Lees “Android multitouch gesture detectors” verder

VisualVM and fixing remote JVM problems
(I’m sorry, the blog and company I link to don’t exist anymore, the company was bought by another company)
I wrote an
article about how VisualVM helped fixing a problem I had on my day job at TTY Internet Solutions some time ago. The CPU load on a webserver became to high and the performance of the webapplication dropped ofcourse.
Now, with JMX (Java Management Extensions) you can (remotely) connect to a JVM (Java Virtual machine) and take a look at what’s going on in that JVM. A great tool to do this is VisualVM. In the article I explain how we setup JMX on the remote server, how we connected VisualVM, how we read the info VisualVM gave us and how it helped us find and fix our bug.
Experimenting with Firefox Audio API
As I am an electronic music creator and a software developer, guess what I like to program ;)… Yes, DSP (Digital Signal Processing) and audio stuff. About two years ago I worked on a DSP platform in Java which became to big of a project to finish.
Recently (april 2010) I found out some guys at Firefox (David Humphrey, Corban Brook, Al MacDonald, and more) are working on an experimental Audio Data API build on the HTML5 audio tag. This I had to experiment with!

How to create a CSS3 tag cloud like on this blog
As part of my CSS3 try-out (also read my post on why I started using CSS3 on this site) I created a tag cloud that’s designed with CSS3 features. You can find the tag cloud under each article on my blog and also on the right on every page. In this article I’ll explain how you can create this CSS3 powered tag cloud yourself?

Why and when to use CSS3
If you browsed to this site with a latest version of a more modern browser like Google Chrome, Apple’s Safari, Mozilla Firefox or Opera you are looking at many CSS3 features. If you are watching this site with IE you won’t see any of the CSS3 features and you might think this site looks pretty boring (well, you might think this anyway ;)). But the CSS3 usage should degrade gracefully making this site still available for you die hard IE users out there. Lees “Why and when to use CSS3” verder
404’s on WordPress Permalinks (IIS with ISAPI Rewrite)
So, one day I decided to start a blog. I had available a windows server with IIS 6.0 and I PHP enabled it some time ago. After some looking around I found WordPress was what I wanted to use. The whole installation works like a charm and with not much hassle. But for SEO reasons, I wanted to use WordPress’s permalink (common structure) feature. For this to work you need a URL rewrite solution. Apache can use mod_rewrite here, but on IIS we could use for example Helicon’s ISAPI Rewrite Lite. I installed it following Kyle Caulfields manual. But… it didn’t work for me unfortunately. Lees “404’s on WordPress Permalinks (IIS with ISAPI Rewrite)” verder
