Gary Sims is a freelance Linux/FreeBSD consultant and writer from the UK and has been working with open-source software since the mid 1990s. He first saw Linux while completing his degree in Business Information Systems at Portsmouth University. Then while working for Digital Equipment Corp he came in to contact with DEC's Ultrix and later Digital UNIX (formerly OSF/1). While developing enterprise software for DEC on its UNIX platforms he became more and convinced of the benefits of open source and open-source Unix-like operating systems like Linux and FreeBSD. After leaving DEC he became a software contractor and after moving to Romania in 2003 he became a freelance Linux/FreeBSD consultant and writer and started publishing articles for the Open Source Technology Group (owners of Linux.com and SourceForge.net). This then led to him writing his first book with Packt.
