I have always been obsessed with simplicity when it comes to programming. To me, there is nothing more frustrating than complex, buggy and sluggish software. In 2005, I had to write a web-based application from scratch to process and display intrusion detection events. At that time, I looked at a number of web frameworks but didn't find anything that suited my needs. So, I created my own framework called Hamlets with simplicity and speed in mind. In 2007, IBM agreed to open source this framework under a BSD license. It is now available from sourceforge.net. A short description in English, German, French, Spanish, Catalan, Dutch, Finnish, Russian, Italian, Romanian, Danish, Czech, Chinese, and Serbian can be found on Wikipedia.

The Key Management Interoperability Protocol (KMIP) defines the communication between a Key Lifecycle Management System (KLMS) and its clients. This protocol origined at the IBM Zurich Resarch Lab. I had the opportunity to contribute to KMIP. For many years, there was no open-source solution. To increase the popularity of this protocol, I initiated the Java open-source implementation of KMIP 1.0. The software itself was developed by Stefanie Meile and Michael Guster at the University of Applied Sciences NTB - Interstaatliche Hochschule für Technik Buchs. It can be found here.
