Welcome to the Programming section - the main element of my little homepage.
Here you can find full-blown applications as well as little demonstrations and code snippets of various algorithms coded in different programming languages.
Please keep in mind that every item was developed in my spare time - so I do not gurantee that the implementations are correct and error-free (actually I even doubt it...). My main motivation is solely interest and gain of knowledge - and I hope to help you(!) with the content of this site.
Everything is published with MIT licence, so everybody may use parts of it for anything he or she wants to do - still I would be pleased if you add a link to my site then. Further I would be glad to hear who I could help or in which project/topic an item of my site had helped.
