Summary

I've been a serious Macintosh and Unix user and developer for many

years, and I see Mac OS X and iOS as an exciting platform to develop for.

I pride myself on learning technology as deeply as I can and helping

my friends and associates learn about it. I like to think of myself

as the guy that everybody still turns to for technical advice - not

only do I know (or can find) the answer, I'll take the time to tell

you.
