LinkedIn http://www.linkedin.com/in/jmdots Summary I've worked in technical administration, technical support, customer service or leadership roles for all but a few months of my adult life. In this time, I climbed the ranks of a highly-modern, lightning-paced, large-scale, multi-OS supercomputing environment in Area B of Wright-Patterson Air Force Base (WPAFB) and became an avid user of all things open source. The place which was my professional home of over six years is known as the “Air Force Research Laboratory DoD Supercomputing Resource Center” or "AFRL DSRC" for short. The AFRL DSRC environment is home to the #19 supercomputer on the June 2011 Top500 Supercomputer List, a mammoth computer for which I received training: Cray Inc.'s "Raptor" XE6.
