comment Efficiency of python script using SAGA and arcpy
That's a different project with the same name: you should look to sourceforge.net/projects/saga-gis/files/SAGA%20-%202.0/… and check for python 2.6 or 2.7 (whatever you use). I have no experience with using python on windows - better ask for help on the saga user forum

comment Efficiency of python script using SAGA and arcpy
I'll try to add a more documented script later. Unless you explicitely save a file to disk it will be in memory. Eg in the first sample 01_... p('GRID') is a grid in memory. You could pass it to a different module if you want.

comment How to migrate GDB data into PostGIS without ESRI apps?
@Gerson Galang: from that same page: (replace /usr/local/FileGDB_API with whereever you extracted FileGDB_API_<version>.tar.gz)

If you have the File GEodatabase API, you could convert directly using GDAL as well: trac.osgeo.org/gdal/wiki/FileGDB

comment Quickly create contour polygons from cost points using OSS for web app
This is also possible in saga gis. Can you provide an example cost_points.shp file? I can write a short script doing the same. It would be nice to see how the performance would differ from grass.

comment What is Lanczos resampling useful for in a spatial context?
I've integrated your comments. But within the cell, the smooth interpolator would most likely yield a better prediction
