This page has a “closed source” section now. You will find various software projects there, written in a number of languages, for a variety of clients. Full source code is either not available because I do not any longer own the rights to the project, or the code uses proprietary components which I have no distribution rights for. Furthermore, the literature section got extended with many of the articles I have written last year, mostly dealing with C++, Objective-C++, and Lua.
