comment DTM Extraction/Smoothing in ArcGIS
Have you tried making a LAS Dataset and manipulating it using the LAS Toolbar built into 10.2? It helps you classify data - you can view by cross section, etc. You could then subset to the points you want - There's a pretty robust LAS Dataset to TIN tool.

comment Are there any attempts to replace the shapefile?
I know this is really delayed off the original, but as an update in case anyone else finds this - ESRI quietly (very quietly) added Spatialite support to ArcGIS 10.2. So far, using it is pretty seamless, but the databases can only be created in ArcPy (but used everywhere). Converting tables with large text fields also seems to be a problem, but it's otherwise workable

comment Errors while running Region Group tool
I'm always inclined to listen to @whuber, but if you were trying to debug this yourself further, try using GRID format inputs and check your scratch directories in your environment settings. Spatial Analyst is often fickle about personal/file geodatabase datasets in my experience. The only way this works though is if the tool manages to chunk the data so as not to load it all at once. Not sure if Region Group can do this or not.

comment Cannot install ArcGIS for Desktop 10.2 following install guide on Windows 8
Also adding to @MichaelMiles-Stimson - in Windows 8, no need to extract or use Daemon tools - Win8 will mount an ISO as a CD drive natively.

comment Optimising map cache creation performance in ArcGIS for Server 10.2.1
Try opening up Resource Monitor and see if anything is hammering the hard disk. You can also check with something like sysinternals procmon, but my experience with ArcGIS is that I'm bound by disk I/O much more often than CPU.

comment How to improve performance when using ArcGIS cursors in Python with big tables?
@StéphaneHenriod - as a suggestion, you might consider editing the question to add these additional specifications. Given the initial question, I think this answer makes tons of sense, but with this new information, Barbarossa's answer looks good.

comment Why is GPS a free service?
Yeah, but their competing system is also available for public use, so expect devices to use both in the future. The Garmin GLO uses both for additional precision (more satellites in the sky).

You can also check for the existence of C:\Python27\ArcGISx6410.2

comment Network geoprocessing in ArcGIS
This isn't necessarily in the same vein as you're thinking of, but you could do a Snap to the lines, then a spatial join (or if they're already really close, as spatial join with a small buffer). Otherwise, I'd check to see if ArcHydro has the tools, rather than network analyst

comment Export data driven pages only in changed mxd, with arcpy script
This is a bit more complicated, but if you have access to the Data Reviewer extension, there should be a way to figure out what changed for each thing you've mentioned. You'd then need to find a way to map those changes to the pages and export the correct ones.

comment python.multiprocessing and “FATAL ERROR (INFADI) MISSING DIRECTORY”
Three suggestions - two could be related. First, I'd dump the import of arcgisscripting - it's included as part of arcpy. Second, the first line of your try block checks if the file exists, but doesn't do anything with that information, so the check doesn't help the program. You should try an "if not arcpy.Exists(infile): {do something here to handle that}. Lastly, try making your exception handling more robust with the traceback module. It might give you a better pointer to where this issue is coming from.

comment Can you successfully migrate arcgis 10.0 mxd to 10.1 or are there steps to follow?
also, for troubleshooting, it'd be helpful to know if you tried opening these datasets in ArcCatalog or a new map document and experienced the same missing data

This is a long shot, but is it possible you're experiencing one of these issues? support.esri.com/en/knowledgebase/techarticles/detail/…

comment Whether to use File Geodatabase (*.gdb), Personal Geodatabase (*.mdb) or shapefiles?
One con I'd add to shapefiles is the field name length limit. Since they use dbfs as the table storage, they're only 13 character names, which often results in names like "CALUAFID" - not very useful to someone unfamiliar with the data, and engrains bad habits in new users who aren't used to anything else. All the benefits you mention are true. I'd also like to add that the database/feature class precision can be set, so if incredibly high accuracy is important, you still can work with them, but you must be mindful
