comment RuntimeError: Field is not editable when using InsertCursor on ArcSDE geodatabase with ArcFM installed?
Would you be able to remove your try/except statement to let Python display more of an error message and then post that, please? And something else I often recommend doing is to try substituting your ArcSDE feature class for a file geodatabase feature class to see if this is the Python code rather than ArcSDE.

Would you be able to edit your question to include a diagram, supported by example input and out tables, to better illustrate what you are trying to describe, please?

comment Habitat connectivity — how to map connectivity between polygons based on a separate polygon layer
Would you be able to edit your question to include a diagram of a small example area of what you are trying to describe, please? I suspect that a combination of Intersect and Poylgon Neighbors, and probably some ArcPy would do it.

comment Cause of Field Calculator UnicodeEncodeError: 'ascii' codec can't encode character u'\xf6' in position 5: ordinal not in range(128)?
Does this code work when you run it from an IDE like IDLE? If it does, then it may point to a Field Calculator issue, but, if not, then I think it is better researched/asked on Stack Overflow.

comment Running ArcGIS Data Reviewer using ArcPy?
If you are willing to share that code then do not be afraid to share it here as a second answer to your own question, which it is also permissible for you to accept. This could help you to accumulate some reputation points towards unlocking some more GIS SE privileges.

comment My map is little bit off
This Q&A may be worth you reviewing. Do not be put off if it mentions ArcGIS rather than QGIS because the same principles apply. Also, do not be afraid to edit your question to make your descriptions of the steps you have undertaken more precise. Before any answers are offered is always the best time to do this.

comment How do I change graduated color class values with python?
I would try to get it working on a sample dataset copied out into a file geodatabase feature class first. If you are not using this GraduatedColorsSymbology example 2 to model your code on then it could be worth doing so.

comment Ortho-rectification of Aerial Image
It will be useful if you can edit your question to include all the clarifications that you are supplying in response to requests as comments. Some potential answerers only look at the question itself because they do not have time to read the comments.

comment Can't send an array via Protocol.HTTP()
Something to be aware of is that any answers (and questions) that are shorter than about a paragraph get flagged up for review because often answers of such length provide insufficient information about what the answer is based on (experience, link to a bulletin board, etc). If you are able to edit you answer to provide some more supporting information I suspect it will be far more likely to attract some upvotes too.

comment Populate a layout text element with the description from a coded value domain
+1 for including an NIM number but is there any chance that you can include the name and description of that here too?

comment Setting Zero values back to NULL
@EdixonGutierrez The answers here all relate to ArcGIS so I think you should edit your question here so that it only relates to ArcGIS for Desktop. Then if you also need an answer for QGIS please research whether that has already been answered here first, and if not, then ask that as a new question.

comment why isn't the GISP Certificate called the ArcGISP or EsriP?
Having been part of the Surveying and Spatial Sciencies Institute (SSSI) panel in Australia to assess GISP-AP (GIS Asia-Pacific) application portfolios, which is based on and affiliated with GISCI, for four years, I can assure you that knowledge of Esri products was definitely not required and conferred no advantage. Attendance at conferences, undertaking training, working with, etc any of the GIS software mentioned, as well as many others, carries equal weight.

comment Converting from ArcGIS TIN to LandXML?
@ChrisW I think you should write that as an answer, it is useful even another answer emerges.

comment How to merge Shapefiles from multiple folders into Geodatabase Featureclass?
Have you tried running it from an IDE like IDLE which comes with Python? That message looks like you have perhaps double-clicked on a *.py to execute it.

comment How to merge Shapefiles from multiple folders into Geodatabase Featureclass?
Would you be able to edit your question to include what is printed back to your Python window when you run this script, please? And also include any error messages that you may be receiving.

comment Area of an EPSG 27700 polygon
Welcome to GIS SE! Some of our protocols can take a little getting used to but one of them is that, as per the Tour our Q&A format works best if you ask just your most important question first. There is an edit button that you can use to focus your question in this way, and your other question can always be researched/asked separately.

comment Performing transformation from GHANA GRID to WGS 84 using QGIS?
@JohnMaxwell As someone new to GIS SE, I hope you do not mind me suggesting that, since you asked how to do it in QGIS and AndreJoost has described the process for you, it seems only fair that you click the green Accept tick and upvote his answer.
