Mark Bartelt has been having fun with computers for more than fifty-five years, getting his start with Fortran II on an IBM 709 (the last vacuum-tube model which IBM produced).

His areas of interest include parallel computing, system and network security, software portability, and system administration in heterogeneous UNIX environments.

Although his love of technology has been both long and deep, he jokes that he's nonetheless a bit of a neo-Luddite, considering the automobile, the television, and the cell phone to be three of the five worst inventions of the twentieth century. He eschews most of the high-tech gagetry of the modern era, acquired a television only reluctantly, and a cell phone even more reluctantly; and he has not owned an automobile for more than fifty years.
