David Warner is a senior programmer and DBA at Federal Data Corporation. He has been involved with programming since 1980, when he was introduced to DBase II on what had to be the only CP/M-based laptop then in existence. Unix took over his life in 1984, and exposure to Perl in 1991 only made matters worse. Since leaving the Navy in 1993, David has been the CTO of a small medical software company, a consultant and a DBA. His technical interests are cryptography, statistics, relational databases, and linguistics.
