My Identicon looks like four shurikens with big arrows pointing at them as if to say, "This dude's Identicon has shurikens in it. SHURIKENS."

comment Rename a SpatialPolygon class object in R
The output of dput(tmp2) might be more useful - it would give us something to play around with. E.g., it would be helpful to be able to see the results of str(tmp2), class(tmp2@polygons), str(tmp2@polygons), and so on...

comment File organization for sharing ArcGIS python code
Anyone who finds this workflow appealing should definitely take a look at the version control software Git and its popular repository-sharing website, GitHub. It gives you all of the above - a master script, defined privileges, and broad accessibility - with the ability to track all the changes made to the script (including date and author), experiment with new features while preserving the production version, manage multiple editing the same files simultaneously, etc. It's more complicated to use, but I've found it to be immensely useful.

comment [R]Function to calculate mean for missing or NA values in a dataframe
@GodinA I think that your best bet in that regard would be to start thinking of your data as two correlated time series. I don't have much experience with time series data myself, but the topic of missing data in time series comes up a lot. Check out this search on stats.stackexchange.com - I think that'll get you started, at least.

comment Buffers of public transportation transit times
@dassouki I'd love to tell you, but I unfortunately haven't had time to work on anything but research in months. This is the month in which most of my research projects are wrapping up, however, so I sincerely hope to have an update by the end of the year.

This is a great idea, but the title of this question cracked me up nonetheless.

@DEWright, that's an interesting idea - even more so for another question of mine. Thanks!

comment Data ETL workflow optimization
Would he be able to schedule this process, too? I personally think that it would be legitimate for you to compare and contrast with other methods because you've disclosed your connection to the company - and hey, he's already got the software, so it's not like you're going to trick him into buying it :)

comment Visualization to inference workflow
Broadly, I'm just interested in how people incorporate statistical inference into their mapping processes. What you describe is certainly one possible scenario, but there are lots of others and I'm not even especially interested in responses from epidemiology.

comment Buffers of public transportation transit times
Based on my own experiences with the public transit here, I don't think constant velocity is actually a reasonable assumption here. Proximity to an express or regional bus could make a big difference for people in our outlying areas, especially since we're very close to the routes of some of those buses. Then there's the light rail...

comment What was the rationale for the non-standard UTM zones near Norway?
This is a wild guess based on almost no actual facts, but it's been so long since I've even been able to guess at answers here: Submarines. The Germans had tons of U-boats based in Norway during the Second World War.

Good question - I'm interested in the US broadly, Colorado in particular, the Front Range counties precisely.

Note: I found out some time later that the Google Maps directions API doesn't permit use of the public transit mode - just driving, walking and bicycling.

comment Can I get some recommendations for an Open Source Trouble Ticket system?
... or even StackOverflow. Even though that community is mostly programmers, you'd almost certainly find excellent advice there. Just specify your needs clearly.

comment What are your biggest challenges as a GIS developer?
I'm a statistician, and I have very similar complaints about ESRI products. My overly-optimistic theory is that, because computers were probably applied to stats before GIS, GIS software is about ten years behind statistical software (in its SAS/SPSS phase) and that a truly outstanding open-source program or stack is on the verge of breaking out. Maybe it already has - it's been years since I've had the chance to play with non-ESRI programs.

comment List of desktop GIS FOSS case studies
When you're asking a question where the collection of answers is the answer (here, all the various case studies) you should make it community wiki. Each case study should get its own answer, and then people can vote them up or down based on how interesting/useful that particular study is.

comment Define “geospatial data” for a non-GIS professional
Sorry - I intended that the counties/populations list would be implicitly located within a state and country. Heh - you can tell I'm in local gov't.
