The contents of this section are just a tiny extract of my daily projects and interests. My interests are mainly programming related, often the design of various things and 'how to get organized best with (.*)'. Programming is still a big part of my life as for other people is watching television - a part of around 20 years. Keeping the interest alive is made by always looking further into new libraries and various programming languages and techniques. Most of my sources of my old programms are lost or somewhere on old drives.

See my github for my past work. Some releases might be found here here as dist package.
