I'm a New Zealand-born, Munich-based programmer, trainer, and writer who has been programming and using various UNIX systems since 1987, and focusing primarily on Linux since the late 1990s. Since 2004, have been the maintainer of the Linux man-pages project (http://www.kernel.org/doc/man-pages/), which documents the Linux and GNU C library programming APIs. As part of that work, I'm actively involved in the Linux development community, providing testing and design review of changes to the Linux kernel-user-space API. I write and deliver training courses on Linux/UNIX system programming and related areas. Those courses draw on many years of teaching and programming experience and a long and intimate association with the UNIX and Linux programming APIs to create superlative training courses.
