A Long story ...
To make it short, it's comes from the English "What the hell", mixed with a NY accent.
This is a scream I had often on my mind when I started studying in the UK.
The umlaut gives a celtic touch to this nickname.
I have created WadRobotFramework, a framework to create robots for Google Wave.
Find it on its own site while Wave lasts
code.google.com/p/wadrobotframework/
More info on it in my publications.
The techs I like are :
Google Wave,GWT, GAE/J, Android, JEE6
Those days, I'm a professional in I.T, specialized in Java, living near Versailles.
If you want to contact me for business, you can find me on Viadeo and LinkedIn or simply send an email (my nickname at gmail dot com).
