comment ArcGIS 10 Field Calculator doesn't notice selection/Attribute Table problem?
I found the opposite to be the case. I'd inadvertantly left one record selected and couldn't figure out why my field calc operation wasn't running on all fields. gis.stackexchange.com/questions/29235/…

comment How do I access a multivalue output parameter from a python script in modelbuilder in ArcGIS 10.0?
Looking at the script, it appears the outputParam var is being used to create a script Parameter than can insert the layer into the map (without the whole script I can't tell for sure). In all honesty, I find Modelbuilder to be convoluted and more difficult to work with than straight Python. I'd be happy to work with you on a Python solution, but I've only ever used Modelbulider for diagraming my analysis.

comment Export each layer in map to a separate image
Since the loop is only looping through layers in the map / in the list it's definitely not an infinite loop. Using this code I was able to turn off all layers in my mxd.

comment Export each layer in map to a separate image
See updated script. My mistake I created a script that worked for me, but not all use cases last time. As I say in the script comment, the arcpy.RefreshActiveView may be unneccessary (try without it to see if the map exports correctly). If it's not needed things will run faster.

it's a syntax error, should be arcpy.ListDataFrames

Gotcha, I thought you were proposing to drop them all together. This reminds me of my intro to engineering design course.

comment Indoor Navigation Robot using OpenCV
I think reference to 'real time' collision avoidance might include objects not mapped in the mapped layout of the room. For example if you randomly placed 5 chairs in the room could the robot avoid them?

comment Creating a raster map using Excel file and calculating averages
Depending on the density of your data, interpolation may be a much better way to go.

comment Creating a raster map using Excel file and calculating averages
You'd have to create a separate raster surface for each month's average temperature.

comment How can I handle tables with 256+ variables?
With any amount of DB Normalization I suspect that these huge tables should be separated into several (or many) smaller tables relating back to their Census unit (block maybe?) UID.

comment Creating a raster map using Excel file and calculating averages
It would be helpful to give an example of one row of your data. The workflow I'm envisioning is: Excel Workbook => ASCII Text => ESRI Raster

comment Export each layer in map to a separate image
Have you tried debugging by printing LyrList to see what the specific problem is? Is this for your own purposes or for someone else? I ask because you could do this without creating a script tool; see if it works by creating your own list as opposed to GetParameterAsText.

Would it be helpful to add a Global Unique Identifier (GUID)?

comment Export each layer in map to a separate image
Did you get an error? What about the script isn't working?

comment Why do you use ArcGIS?
Undergraduate GIS education teaches you what buttons to push as opposed to spatial analysis. Many times ESRI supports campuses with free student licensing so that you learn to push their buttons as opposed to someone else's. To that effect, I work for the Fed who also has an ELA with ESRI. They seem to have me surrounded.

comment insert cursor “Row contains a bad value”
The last line of the code is newRows.insertRow(neue), but neue is setup to create a new row... Could that be the issue?

comment arcpy.UpdateCursor for multiple fields
I'm still a bit unclear about what you're trying to accomplish. In your script you're inserting the same string 'FIELD_ERROR_VALUE' into every field. Your SQL statement is static as well, although you commented it may also be less than or greater than, etc.
