comment CartoDB (PostGIS) near function (distance) points to polygons
If it is returning degrees then your projection is in degrees, most likely wgs84. You'll either need to reproject to a different projection that uses meters or feet in its coordinate system, or cast the points as geography. The geography based system returns meters, but the calculations are slower.

comment How to use Python for online GIS?
Not necessarily, but depending on the size of the data your hosting and the types of operations you're running a database could help. PostGIS has built in functions for finding distance, intersects, etc and is a good way to store and serve up data. For example, it can respond to a query with a geojson of your spatial data, and you can display that geojson directly in a Leaflet or Openlayers map.

How are they conflicting? How are they supposed to be interacting?

comment Open Layers 3 geoJSON not loading
Another solution for those who don't have full admin rights on their server is to rename the .geojson file to .js.

comment How to get Geography data to GeoJSON in PostgreSQL?
What version of PostGIS are you using? If you have a really old version (older than 1.5.0) St_AsGeoJSON doesn't support geography, only geometry. Next thing to check, is PostGIS and its functions installed into its own schema, and if so, is that schema in your search path?

comment Can't get OpenLayers 3 to display data from QGIS Server WMS service
Final fix: Needed to reference the map document itself and pick a better zoom level to start with.

Switching to ol-debug.js did show that it wasn't getting the projection information it needed, your post showed me how to correct that. Thanks!

comment Can't get OpenLayers 3 to display data from QGIS Server WMS service
The projection fix got the map tools to load, but not my map. That's a separate issue that I'll work on and start a new question if needed. Thanks for your help! I fixed the 1.3.0 as well, 1.3.1 was the version of the Capabilities report QGIS server puts out, the WMS service is still a 1.3.0.

Nope, same result, though I'm sure that this solves the next problem I would have had getting this running. Also, EPSG:2966 is in ft, I assume units: 'ft' is correct, or no?

comment How to draw a polygon given a distance and bearing in QGIS
This is one of the biggest features from ArcDesktop that I miss. All those functions when you right click as your creating / editing features are so convenient. Point at the end of a line is another.

comment ST_Intersects incorrectly returning false in PostGIS
use addgeometrycolumn() if you're using a version of PostGIS older than 2.0, from 2.0 forward geometry_columns is a view that is autopopulated. When you add a new geometry column and typemod it to a certain SRID that SRID is picked up by the view automatically.

What values are showing up in that field? Does that field have a domain on it when viewed in Arc?

comment GDAL not accepting *.tif to list through files in directory
As to why it is working if you look at the script itself it does not import glob, the module python needs to do file expansion. It is literally looking for a tif file named *, not all files that end in .tif.

comment QGIS howto create raster from map canvas easily
You can install version 2.1, which is the development version that will become 2.2 with the OSGeo4W installer. Select "Advanced Install" then in the Desktop section choose qgis-dev.
