Introduction

Welcome to my web site, which was orginally created for my my UNIX and Linux training and support business. Now I'm using it mostly for my photography - not a business, just a hobby. I still use Linux, but don't operate my own business any longer. Previously, I provided UNIX and Linux administration services, and delivered hundreds of training classes covering basic and advanced UNIX and Linux user skills, system administration, and Shell, Perl, and C programming.
