comment Why doesn't CartoDB display my data?
The OP did mention that the data is georeferenced (at least CartoDB says so). Maybe it's lying? :)

comment How to Buffer with Dissolve ALL on very large polyline dataset?
Is your data in an enterprise geodatabase? Maybe this could be accomplished more efficiently through SQL.

comment How to efficiently change all source/output files in an FME workspace?
I would be careful with this. Some strings are encoded in "interesting" ways, and if you mess something up, it's liable to corrupt the workspace. Always make a backup, and do things through the UI unless there is no other way.

comment How to return value into a python list using search cursor
Are you working with numpy? Check out the arcpy.da.FeatureClassToNumPyArray function if so.

comment How to return value into a python list using search cursor
arcpy.da.SearchCursor rows are already tuples. So what is your question?

comment How to add an ID based on attributes in ArcMap 10.1
There are some ideas and SQL-based solutions in this question for a related but not identical problem: How to number polygons according to their spatial relationships?

comment Writing a script for accessing QGIS tools for use in HTML WebPage
You have thrown out a list of disjointed technologies and a vague goal, but based on the lack of responses thus far, I think you need to do some more research on your own to narrow down the problem size, provide details, and write a focused problem statement. As a starting point, Python is the de facto scripting language for many GISes, so maybe you can look into using that. You also need a way for your web server (which you have not yet described) to be able to serve up the output of your script, so look into that as well.

comment How to add an ID based on attributes in ArcMap 10.1
I would strongly suggest rethinking your design. A unique ID should not have any semantic meaning (like its ordering meaning something). Its sole purpose is to uniquely identify a record. If you want to relate the points to the polygons using IDs, create an explicit foreign key. This can be easily accomplish with a spatial join.

comment Bulk convert DBF to CSV in a folder ArcGIS 10.1 using Python
Based on my testing, ListTables() will not list DBFs associated with shapefiles. So you'll have to either combine this with ListFeatureClasses(), or use ListFiles() or Python's glob() or listdir() functions.

Are ALL of the DBFs you are talking about associated with shapefiles, or only some, or none?

comment Maximum length of path using arcpy?
If you don't include your code there is no way we can help you. My guess is you've forgotten to escape your backslashes.

comment Worldwide places reachable by sea/ocean
The Natural Earth data has various fields that I did not include in the CSV output in my answer, such as population, bounding box, area and perimeter with varying levels of completion. Check it out for yourself. You can use a FOSS GIS like QGIS to view shapefiles, as well as the commercial ArcGIS. There is also an online viewer here: koordinates.com/layer/1287-world-populated-places-110-million

Why don't you browse some listings yourself? There are a number of GIS job listing sites here: gis.stackexchange.com/q/6645/753

comment Worldwide places reachable by sea/ocean
Also you can obviously adjust the proximity. Maybe 20-30 miles is better for some larger cities whose centers are further inland but still have access to the ocean (e.g. Houston).

comment Worldwide places reachable by sea/ocean
Realistically, is there any benefit to going more granular than the 1:10m scale Natural Earth data? What is the resolution of the meteorological data? Does it really matter if someone gets readings closer to their village vs. the nearest city? If you want to be able to match against every mapped boat dock in every port in the world you're basically going to be reimplementing OpenSeaMap. Don't underestimate the amount of data that is. OpenStreetMap's raw data dump, last I checked, is over 30GB, and is constantly changing (growing, primarily).

comment Worldwide places reachable by sea/ocean
Well there is OpenSeaMap (related to OpenStreetMap). Most commercial nav systems are likely to use proprietary data though.

comment Worldwide places reachable by sea/ocean
I'm not sure where you're going with the routing idea, but it's all about the data and how it's prepared and for what purpose. Additionally, a surface is not going to be able to uniquely identify something as numerous as worldwide populated places, only aggregated or continuous data.

comment Worldwide places reachable by sea/ocean
Regarding your update, that begs another question. Do you have a list of populated places which actually have the meteorological data you need? This would almost certainly be a better starting point than all populated places in the world.

comment Python - Find the largest extent in a list of extents (tuple format)
I think that nmpeterson's comment still applies here. It would probably be safer to project the extents into an equal-area projection before attempting to compute the area. GetArea() uses Green's theorem which, from my understanding, does not take into account the fact that latitude and longitude are angular, not linear units.
