So was it 35 countries or 17 countries after all? It's the second time I'm complaining about the Institute of Engineering and Technology and their approach to data analysis.

A sneak preview of the second Tableau Server Users Group meetup in London

Last month was the second  London Tableau server users group meetup. Jonathan MacDonald went through a long list of tips and tricks for server users and administrators, a few I knew already but also an awful lot that I didn't.

I won't go through all of them, as I wasn't writing them down, or snapping a pic for every single one. I did take the following two pics though. The first trick is that you can append filters to the URL:

and the second one is that you can access an xml containing the server status again through a URL

Extracting the list of coordinates for geographic role 'airport' out of Tableau

Don't they say a picture is a thousand words? All you have to do is navigate to 

C:\Program Files\Tableau\Tableau Public 2019.2\local\data

(modify appropriately for Tableau desktop). Copy the airport tableau source and the GEOCODING database into another folder, drag and drop the tds on tableau and voila, you have the airports and their coordinates! You can even export them to csv for general purpose use.
