comment Copy multiple features in feature class, update field value based on number copied
This is an excellent use case for reading your first table using arcpy.da.SearchCursor while writing your second table using arcpy.da.InsertCursor. If you get stuck post a code snippet that works up until the point at which you are stuck.

comment How to create a range domain in ArcGIS with an interval of 10
@alextc That should be a separate question but I would use arcpy.da.InsertCursor with a loop to write a table that you convert with Table To Domain.

comment Move points along a line, 100m left or right
This sounds like linear referencing. If you edit your question to include a description of your data and the precise steps up to where you were stuck then it is likely to attract an answer related to that.

Would you be able to edit your question to indicate where you have looked and whether or not you have contacted the software developers, please?

comment addins vs python tools, which makes more sense?
I think the answer to 1 is that ArcObjects is much more suited to build an editing add-in for ArcMap than Python at 10.1, and the answer to 2 is however long your users continue to use ArcMap rather than ArcGIS Pro for editing, but overall I think your question is either too broad (has two distinct questions) or too likely to generate opinions on when ArcGIS Pro will have sufficient functionality to fully supersede ArcMap.

comment arcpy.Clip_analysis() Automatically Affixing .shp.shp to Target Feature Class Name?
I'm probably not the only potential answerer who would miss seeing the output of your print statements recorded as in code comments. I recommend using a separate Comment block which the Stack Exchange editor lets you do easily using the " button.

comment Avoiding schema lock cannot be acquired because of existing lock on File Geodatabase?
I agree with @nmpeterson - the use case for ArcCatalog since the release of 10.0 has been very limited - with the Catalog window available just stay in ArcMap, and you should see far fewer, if any, schema lock issues.

Would you be able to expand upon your very brief answer perhaps by referring to some relevant documentation, please?

comment arcpy.Clip_analysis() Automatically Affixing .shp.shp to Target Feature Class Name?
Would you be able to edit your question to include just a code snippet that works up to where you believe Clip_analysis is appending ".shp" onto a feature class name twice, please? By doing that I think you will discover what may be astray with your code, or if it is a Clip_analysis bug, then that will then become apparent. Your question could also be improved by including the current output from the code you have currently included but it will be best to remove your try/except so that more of the error is viewable.

comment What is the file structure of an ArcGIS Place File?
To load an existing bookmarks (*.dat) file into ArcMap you can use, Bookmarks | Manage Bookmarks and then the Load button on the Bookmarks Manager. I just tested this at 10.2.2 but I think that has been there since about 10.0. I think there was only a brief window during 9.x where My Places had some functionality not in Bookmarks, and I now recommend using only Bookmarks which are more accessible and just as functional. cc @RyanDalton

Would you be able to edit your question to include the precise procedure you used and an accurate description of what in the result was not as you expected from the documentation, please?

comment Benchmarking QGIS and ArcGIS for Desktop speed for “significant buffer on very large shapefiles”?
When benchmarking it is important that you are undertaking a fair comparison. In this case you seem to have made the shapefile format a requirement but not nailed down much else. I think you should edit your question to start including details like the common configuration and dataset that each should be tested on using the latest released version of each.

comment What is the file structure of an ArcGIS Place File?
I saved a bookmark from ArcMap 10.2.2 as ".dat and the format looks binary so I think ArcObjects may be needed to make sense of it.

comment Shapefile not projecting correctly
I suspect that this ArcGIS Q&A may provide ideas for what to do in QGIS: gis.stackexchange.com/questions/20572/…

comment Distributing processed SRTM data legally?
In the meantime I recommend editing your brief question to include more of the details that you only mentioned in comments. That should help prevent any further downvotes.

comment Where can I find information about the development history of QGIS?
"most" rather than "almost all" may be a better wording above.

comment Where can I find information about the development history of QGIS?
@whuber I would suggest that almost all (but not all) multiple question posts should be closed as too broad. My trigger for too broad is when answers are expected that need to be cross-referenced to the parts of the question to which they relate.

comment Where can I find information about the development history of QGIS?
@whuber I was not suggesting that five questions be asked. Just asking who started QGIS would probably have uncovered most of the same information but I suspect a Google search could be done first to find that and focus it to something harder to find.

comment Where can I find information about the development history of QGIS?
I think this is too broad for focussed Q&A because it asks five questions and does not indicate any research undertaken prior to asking each.

comment Missing field in address locator when geocoding
Would you be able to edit your question to include the GIS software and version that you are using, please?
