[edit] Areas of Interest
I am an amateur radio operator, callsign K6WEB, and am most interested in ham-related technologies that push the envelope.
I am fanatical about standards, as I believe that their appropriate use can enhance the usability, advancement, and interoperability of all kinds of technology. The areas where I am currently most interested in the promotion of standards are amateur radio, mobile phone technology (including WAP 2.0/XHTML Mobile Profile), computer hardware, and human-computer interfacing.
[edit] Employment
I am currently a technical marketing manager at NVIDIA Corporation, involved with our professional graphics products, including the NVIDIA Quadro FX graphics cards. Prior to this, I worked at HamStop.com, and CMP Media, where I was an editor on CADENC magazine and later Game Developer magazine.
The various Web sites that I have created or maintain:
