comment Changing alias of ArcSDE feature class?
My first guess is that the table is marked open by another user or process so edit is not available. One of the sde lock questions might help. I don't know about SDE but it's not uncommon in file-gdb for a person to be locking themselves by having more than one ArcMap session open, or be looking at a feature class item description in the Catalog pane as well as map, and so on. Also check Task Manager process list for ArcMap/Catalog sessions that didn't close properly.

comment How to correct topology area boundary errors (slivers/gaps) on arcs in arcgis / arcsde
If you still have it hanging around that custom snap tool might have life left! I found this question looking for a way faster than using the Map Topology Align Edge and/or Edit Reshape Feature tools.

comment How to correct topology area boundary errors (slivers/gaps) on arcs in arcgis / arcsde
Pushing precision/accuracy proviso aside, hearing there are still problems with vertex coordinates changing in unedited parts of the feature class is worrisome. In the past we called this "coordinate drift" and "shifting". Here's my notes on it from a dozen years ago: old.yukongis.ca/oldsite/DataShiftOnEdit.html, with links to some long and heated threads in the Esri forums. I would ensure both of your feature classes are contained in the same Feature Dataset before editing and see if that helps (it forces identical coordinate systems and spatial domain).

You might press legal department for a definition on what "must not be changed" means. Point out to them that if a professional surveyor's hard copy paper map is considered a legal and definitive record (likely), then the digital representation of that line has some corresponding fuzziness (the width of the pen mark is likely larger than the majority of difference you're seeing). There's a difference between "precision" (number of decimal points) and "accuracy" (degree of correspondence to real world).

Integrate doesn't meet the requirement that "the initial layer must remain unchanged" as it modifies all participating layers. As far as I know the only way to do this now in the Esri ecosystem is to go all the way back to arcinfo-workstation and coverages. (I'd love to be proven wrong.)

comment Unmanaged Raster Catalog Relative Paths?
from Esri forum thread Relative Paths in Unmanaged Raster Catalog? it seems personal-gdb is allowed relative paths, though that may also have performance issues. Also please consider voting for ArcGIS Idea - Relative path names for mosaic datasets

comment How to save Result File from command line arcpy?
@EvilGenius adding a script to a toolbox tedious, so I tend to avoid it unless it's something that warrants the extra work. Consequently only about a 3rd of the scripts I use end up being recorded. :-/ The idea of a generic "run this" tool is interesting. I might explore that.

comment How do I get statistics out of a table using Python in Arc 10?
Nice clear example. I added some code comments to help the python beginner this Q is aimed at. For better portability use arcpy.Describe() to retrieve the name of the Area field, example at Determining Shape Area Field Name

comment Enabling public viewers and private editors of feature service on ArcGIS Online For Organizations?
Note July update in my post. New groups with "members can update" permission can now be used to protect feature services, making this approach viable for public feature services. Removing downvote.

comment Enabling public viewers and private editors of feature service on ArcGIS Online For Organizations?
As of 2015-Jul-14 the "set read-only, override at edit time" workaround is improved: org admin can create a group with Members can update items permission. This removes the need for shared login credentials and/or giving all editors organisation-wide admin privileges.

comment Command-line utility to convert GPX into KML?
You're probably looking for ogr2ogr. See the duplicate Windows script/application to convert GPX to KML? (this question is phrased better, the answers over there are applicable).

comment ArcObjects + comtypes at 10.1 and newer
An alternative to deleting the cache manually is to (re)create the cache with comtypes.client.GetModule( 'filename.olb' ). See github.com/maphew/arcplus/blob/master/arcplus/ao/test.py (worked for me, may not elsewhere).

@user28510 Please post this as an answer and then accept it. After all it is the solution that worked, and others will discover the answer more easily when it's not buried as a comment.

comment Using boolean parameters in Python Script Tool of ArcPy?
Also note the type changes from string on command line to unicode from toolbox. See my answer that explores PolyGeo's answer in some more detail. Bottom line: always test strings and pretend you don't know about booleans.

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)
