I'm impressed Tim and would endorse the GeoDjango idea. I've so far
compiled GEOS can import it in Python, but that's hardly more than
getting my feet wet.
I'm going to tell my GIS audience to make sure to visit your booth
(I'm doing this on the basis of teaching core Python to ESRI product
users in 2005 at a DoubleTree by Lloyds (might've been Red Lion back
then?) -- spent a lot of time showing how decorator syntax could be
used to take the derivative of a function, which was later decided
wasn't such a great idea on edu-sig, Guido contributing).
I was pushing Django heavily for that Ecotrust Foodhub proposal, which
obviously sank to Davy Jones with no trace, but I'd noticed the
PostGIS angle and was thinking here was room to grow -- didn't know
about GeoDjango back then, wondering if FoodHub went with something
like that (a long time ago, I contracted with Ecotrust to do
membership tracking in Foxpro, because it ran on both Windows and Mac
back then... sounds of dinosaurs stirring).
Anyway, GIS/GPS is very Portland, given our reputation for most
excellent planning. I wonder if Metro uses much Python (just met with
Phyllis Cole yesterday but we didn't discuss it). My dad was an urban
planner here in town before we moved overseas. No one had computers
back then, or cell phones. How did we do it? I was learning New Math
(probably why I'm pushing Gnu Math today (because the Russians are
Thanks again to all who helped with my stupid static serve problems
with Django. It's hard on my ego to feel this retarded but that's
what we must go through w/r to anything new and unfamiliar (I've
managed to live this long with very little need for regular
expressions, whereas now they're the key to fame and glory -- found
that FireFox plugin that's lets me play with 'em).
