I’ve been involved in a few IT related projects over the years.

In the 1990s, I was extensively involved with Novell’s Directory Services, was one of the four people that engineered the initial University of Florida NDS Tree (the forerunner to Active Directory),
and presented a couple of talks on topics such as IPX SAP Filtering (warning, 1990s era PPT slideshow) at conferences like Brainshare and Novell’s Technical Transfer Partners.  I also discovered a few security holes in NetWare, and products designed to run on NetWare.

In the 2000s I shifted gears and moved into the realm of Unix and Linux systems administration and engineering.  I contributed some code to the OpenBSD 3.1 tape driver, but I don’t know if that was ever included.  I’ve also been known to submit a few patches here and there to other opensource projects.
