About Me
David Gadd
Orlando, Florida, United States
I'm a Gemini, mercurial persoality, I jump around in n-space. I'm an avid, though bad,
guitar player. (I have an Ovation acoustic/electric 12-string) Current interests in
simulation technologies, AI, and expert systems. Real AI and machine learning not rule
bases.
