Tony Steidler-Dennison is a longtime Linux user, dating his first experience with Linux back to 1996. He's used Linux as his sole operating system at home, developed software on Linux systems, and administered such systems in environments as diverse as robotic telescope control, online shopping, presidential politics, and commercial aviation. Tony has coauthored two books on Linux and over the years, he's written more than a dozen magazine articles on topics from Drupal and content management systems to podcasting with open source tools. Since February 2005, he's engineered and hosted "The Roadhouse Podcast," a weekly hour of "the finest blues you've never heard." Since the purchase of an Intel-based Mac Mini, Tony has become both obsessed and fascinated with the operating system he calls "Linux with a pretty face." Tony is an avionics systems engineer with Rockwell Collins, Inc. in Cedar Rapids, Iowa, engineering open source solutions in the commercial aviation industry.
