comment I am clipping my data points but the clipped layer is empty
Sorry but there is nowhere near enough information to help you. Please review the help center for how to ask questions that will generate useful responses.

comment What is CID field created by Create Random points?
Thanks. I guess the "C" could be for "Common".

comment Automate Exporting of Rasters Using Renderer in ArcGIS
Encourage Esri to expose the renderer to arcpy by voting for this idea at Expose Export Raster Renderer Settings to Python/Arcpy (repost of JKyllo's comment above; wording didn't make it clear what is at the end of the link)

comment Batch Convert GRID to TIFF with colormap and RGB
Related: gis.stackexchange.com/questions/140196/… (though unfortunately the answer still seems to be "you can't get there from here", until someone provides enough of an example of getting at the renderer via ArcObjects)

comment How to Edit Reference Styles in ArcMap 10
Esri published how to edit .style files using MS Access in 2007: blogs.esri.com/esri/arcgis/2007/10/30/…, so there's no concern about contravening a "you agree not to reverse engineer" licensing clause. Redistributing the Esri produced symbols would be a different matter.

comment *.lyr to *.style conversion in ArcGIS
Also useful to know is that renaming .style to .mdb allows editing via MS Access, see gis.stackexchange.com/questions/25414/…

comment ArcGIS - Export raster keep color scheme
@MatthewBilskie you might need to turn off Stretch and Gamma under layer Symbology on the exported raster, see gis.stackexchange.com/questions/104503/…

comment How to Export Raster with same classification colors seen in ArcMap?
@geogeek when the exported layer is brought back in to ArcMap Stretch needs to be None, and probably Apply Gamma Stretch turned off. There can be a slight shift in colour tone/brightness because of HSV <> RGB conversion, but at least it's close. This info discovered at gis.stackexchange.com/questions/104503/…. Also see blogs.esri.com/esri/supportcenter/2011/05/05/… for turning stretch off by default.

comment Adding arbitrary code to ArcGIS ModelBuilder?
Ryan perhaps you could expand on why output is a [P]arameter, and show example of the module being included in another module. I was initially very confused why P for an output, as parameters are usually all about inputs.

comment seeking “Available Sky” implementations
@B.Davis, nothing new from me I'm afraid, it remains a dormant line of enquiry. You might generate some new information by asking a new question by taking one of the suggestions here and detailing what about it doesn't work, is too confusing, or otherwise doesn't speak to your present goal.

comment Install ArcGIS Desktop unattended or silently
Thanks for tip about wpkg, hadn't seen that one yet. Bit about pre-login doesn't apply (to us) because we often have users self-serve the install; we've had too many issues with other deployment tools (e.g. MS System Center, good tool but learning curve too big for part-time sysadmin).

comment Using File Geodatabase with Null values in Field Calculator of ArcGIS Desktop 10.0?
just a general python note: if item is the same as if (item is not None) and easier to read. Likewise if not item is the same as if item == None. I'm not sure if this has any bearing on your Q as I can't test in Arc10 or earlier. FWIW, v1 returns extra Nulls in Arc10.3 also, v3 appears to work properly but beware because mutating a list in place causes unexpected but not immediately obvious mistakes in the results (see here). Bottom line: v2 works, don't use the others.

comment calculating a field in which null values may be present
2 problems in the 2014-Feb-28 update: (a) The EOL syntax error is because of the line break. You need to either triple quote the block, or since it's so short turn it into a one liner: codeBlock = "def stack(*args): return sum(filter(None, args))". (b) In exSummed = you are concatenating or adding the fields together before passing them to your stack function. Needs to be "stack(!item1!, !item2!, !item3!)"

comment calculating a field in which null values may be present
+1 for the example of an unwanted results. There's a syntax error in def stack though, the 2nd myList line is missing =. Also the list comprehension can be simplified to [item for item in mylist if item] -- because if item is functionally identical to if item is not None. See docs.python-guide.org/en/latest/writing/style/…

comment Converting models from QGIS to Python scripts?
The save as python was removed when Modeller was rebuilt using a better system. It's planned to make a comeback in future according to gis.stackexchange.com/questions/121537/…, but that hasn't happened yet.

comment Perpendicular lines at start and end of line in ArcGIS Desktop?
GBG we generally discourage link-only answers. Inevitably they succumb to link-rot and then the "answer" doesn't apply any more. If you can, include something that will allow a future searcher to (re)build their own solution when the destination link has disappeared.

comment Perpendicular lines at start and end of line in ArcGIS Desktop?
Also see Perpendicular Transects ArcGIS 10 toolbox by Mateus Ferreira. It's also for creating perpendicular at regular intervals along the line instead of just at ends, but has an option for deriving the split distance from a field name. Perhaps if the Length field was used it would only do end points.

comment Getting a raster extent excluding nodata area
this is essentially the same question as gis.stackexchange.com/questions/45159/…. The embedded answer should be extracted and placed as an answer and fetch it's due up-votes. (tip: to speed up processing time and reduce redundant disk storage, use a "virtual raster table" (vrt) for intermediate steps).

comment Interactive “for each item in … do …” in QGIS?
I found a higher level doorway through the "iterate over layer" button, see other answer. There is room for another answer to show syntax for using embedded console processing.runalg() with getfeatures(layer) (or equivalent).
