Kurt Wall first touched a computer in 1980 when he learned FORTRAN on an IBM mainframe of forgotten vintage; things have improved since then. A professional technical writer by trade, a historian by training, and an all-around Linux guy by avocation, Kurt’s work history is diverse. These days, Kurt works in the Customer Engineering group at TimeSys Corporation in Pittsburgh, Pennsylvania. His primary responsibilities include building and maintaining TimeSys’s Developer Exchange and working with portal customers and users. He also fixes broken servers, writes documentation, and builds TimeSys software.
