comment What is the most annoying fact about the GIS market/industry?
@MatthewSnape Shapefile isn't widely used because it is so limited. It's widely used because it is an open specification that anyone can implement. Shapefiles require "specific support in the GIS" like any other format. There are Shapefile libraries that make it easy to implement but that would be true of any new open format that might be introduced.

comment Why does DC belong to Maryland in OpenStreetMap/Nominatim?
It's definitely incorrect to consider it a part of Maryland. As others point out, this probably isn't the best forum to address it. File a bug report with OpenStreetMap.

comment How to remove shapefile from PostGIS
Since he didn't specify version and DropGeometryTable is still in 2.0, I figured this was the cleaned way.

comment Why all WFS and WPS are CGI based?
rashad: Are you sure you understand what CGI is? It's a way for a web-server to pass requests on to other applications. It can be slower in some cases but it has nothing to do with HTML5Canvas or SVG. PHP can be used as a CGI. There are CGI for C++ and Java. CGI has its uses when you want a web server in front of your application.

comment Acquiring ArcGIS-like speed in Postgis
It's a common idiom in PostGIS to add a bounding box intersection check to speed things up. Try adding 'AND a.geom && b.geom' to your WHERE clause and see how much of a difference it makes.
