I first became interested in programming, while finishing a Master of Science degree in the biological sciences.
I then spent many years working for a large hospital, supporting its Burroughs (Unisys) mainframes and writing, site-specific ALGOL and NEWP utilities.
I've managed a number of HP-UX Unix servers from release 10.20 through 11iv3 and worked for several years supporting Red Hat & CentOS, versions 5-7.
I am a Linux, bash, and Perl enthusiast, using Apple macOS and Fedora Linux.
