comment Recent Documents list in ArcMap is not being updated
The ArcGIS Discussion Forum had a short thread with no solution on this a couple of years ago.

comment Is there a way to set different levels of transparency (opacity) for a polygon's border and its interior?
I think this question would benefit from the inclusion of a picture to illustrate what you are describing.

comment Displaying adjacent polygon lines beside each other instead of overlapping
Your question is similar to this one (gis.stackexchange.com/questions/85844/…) which uses a similar approach to that in my earlier comment. Also, I think your question would benefit from the inclusion of a picture to illustrate what you are describing.

comment Displaying adjacent polygon lines beside each other instead of overlapping
If you are happy to create a new feature class that you only use for display then I recommend that you try running the Buffer tool with a small negative buffer distance.

comment Why does arcpy.sa.Sample give TypeError: Sample() takes at least 3 arguments (3 given)?
What happened to your third GetParameterAsText? i.e. where is arcpy.GetParameterAsText(2)? I suspect not retrieving it from the dialog will not trigger an error unless what you are getting outshp set to is something you did not intend.

comment Why does arcpy.sa.Sample give TypeError: Sample() takes at least 3 arguments (3 given)?
It sounds like you are anticipating multiple problems so to fit with our focussed Q&A format I recommend that you treat each as a separate question to keep the code element to a snippet that works up to the point at which you are stuck. I too think that arcpy.da cursors would be a better approach to this requirement.

comment Why is this field calculator expression evaluated incorrectly when using Python syntax?
stackoverflow.com/questions/183853/… has an answer that says: "It helps to clarify for the Python 2.x line, / is neither floor division nor true division ... / is floor division when both args are int, but is true division when either or both of the args are float." My understanding is that Python 3.x works the way you originally expected.

comment Measuring Continuous Distance of GPS track in ArcGIS Desktop
Would you be able to edit your question to include a few more details like a screenshot of some rows from your point attribute table (which I am guessing will include a track ID and order), the projected coordinate system that you wish to measure your distances in, and to clarify that it is 10.1 you wish to use (you have a 10.0 tag), please?

comment Opening GeoServer Admin returns HTTP ERROR: 503?
Welcome to GIS SE! As it stands I think your question is too broad because, although you have provided an error message, you have not provided any additional information like the versions of GeoServer, Operating System, and other software you are using, nor have you told us whether this has just been installed, or was working previously, etc, etc. There is an edit button beneath your question that you can use to revise it.

comment How to derive stream order from vector network
You seem to discount the answers (RivEX, NVS Vector Stream Tools) to gis.stackexchange.com/questions/22735/… but without detailing why - can you elaborate via an edit to your question?

comment Converting KML To Layer using ArcPy losing objects?
This is a possible duplicate gis.stackexchange.com/questions/112489/… - are you using ArcGIS Desktop 10.0 too?

comment Missing Raster/Vector Layers after converting KMZ using KMLToLayer tool of ArcGIS Desktop?
I think you should edit your question to try and narrow down your issue which I think is that ArcGIS Desktop 10.0 appears not to be writing two raster and one vector layers from an input KMZ, and as @KHibma commented that may have been a software limitation at that version which has since been lifted. The use of ArcGIS Server and JavaScript/Flex APIs does not seem to be involved in that specific question.

comment Removing highlighting when selecting feature in Arcmap
I do not recall ever seeing selection display behaviour like you describe at any release of ArcGIS for Desktop (8.0 - 10.2). Does it still behave like this after 1. a restart of ArcMap, 2. a reboot of your PC/laptop, and 3. deleting/renaming your Normal.mxt to restore ArcMap's factory settings?

comment How to update Geodatabase point file table from Excel data using FME
Welcome to GIS SE! Would you be able to edit your question to clarify whether your geodatabase table is stored in a file geodatabase (*.gdb) or an ArcSDE geodatabase (in Oracle, SQL Server, PostgreSQL, etc) or another geodatabase type, please?

comment OpenStreetView or points from CSV but not both showing?
Would you be able to edit your question to clarify whether you are using OpenStreetView or Google's StreetView, please? Your title seems to contradict your question.

comment About the storage of GIS attributes
Rather than ask general questions about something that you have not tried yet, I recommend that you first start to work through a PostGIS introductory tutorial like bostongis.com/?content_name=postgis_tut01#304 (please excuse its title).

comment Basin numbering according to Pfafstetter Method?
A starting point may be this paper from 2001 but it is not a subject that I have ever investigated: proceedings.esri.com/library/userconf/proc01/professional/…
