Have worked as a software engineer for 15 years, mostly in signals such as fighter and missile radar, surveillance, and AirTrafficControl, and more recently mostly in C3I (command control commun intell) for UCAVs and in controllers for telecomm. Most work has been to mission-critical, DoD, and/or CMM-level3 or up specifications. Have been using Linux for almost 4 years, doing lots of SysAdmin and make and cm setup as well as software development.
