White Oak Labs has contributed to a variety of the most popular open-source software platforms, as shown below.

Our decades of experience in enterprise software systems research and development provide in-depth capabilities for computer forensic investigations.

The FreeBSD Operating System

Dr. Murphey was a core team developer for the FreeBSD Unix opeating system from 1994 to 2000. However, his involvement began much earlier, in an earlier predecessor system called 386BSD. 386BSD was the first port of BSD Unix to the Intel platform, authored by Bill Jolitz, who was contracted by Berkeley to do the Intel port. Dr. Murphey performed testing and contributed patches to his first "noname" release. Later on, he was involved in a subsequent "patch kit" for 386BSD that accumulated contributions of developers as the following grew. This "patch kit" represented FreeBSD in it's earliest form. Being on the FreeBSD core team was an exciting experience, especially the opportunity to see FreeBSD in use at places like Yahoo and Hotmail in their formative years.

One of Dr. Murphey's principal interests has been FreeBSD's support for the XFree86 window system in the form of console drivers, access to video hardware, general platform support, documentation and release engineering. This form of stewardship was an opportunity to contribute to the productivity of other developers by making it easier for them to use FreeBSD as a desktop.

The XFree86 Window System

Dr. Murphey was a co-founder of The XFree86 Project, Inc., the organization that produces XFree86 window system for Linux, FreeBSD and unix in general. He helped author the by-laws, served as an officer, and member of the board of directors for many years. He was a core team developer for a dozen or so years. Much of that work was focused on platform support for the FreeBSD Unix platform.

The Asterisk VOIP Telephone System

More recently, Dr. Murphey has contributed to the Asterisk Voice-Over-Internet-Protocol telephone system, and it's support for open source unix systems such as FreeBSD.

He contributed support for FreeBSD, OSX and related *BSD operating systems to the Asterisk project and it's maintainer, Digium. He currently maintains the Asterisk PBX project's support for the high-performance, open-source FreeBSD Unix platform, a favorite of internet service providers.

Asterisk is the most popular open source telephone system available. It offers unmatched extensibility, flexibility, functionality and features, and it competes favorably with commercial enterprise phone systems. Voice Over Internet Phone (VOIP) systems have unique cost competitive advantages over traditional telephony.
