As with any good computer programmer, I have used multiple operating systems. I have only mentioned a few of the operating systems:

• FreeBSD - my current favorite
• Microsoft Dos 5.0 - great for playing Doom
• Microsoft Windows 3.11 - first attempt of the Xerox Parc
• Microsoft Windows 9x - another great game environment
• Microsoft NT - first attempt of a server
• Microsoft 2000 - finally not so many blue screens
• Sun Solaris 8 - my current work environment
