Straight from one of the best books I've read on communication (Trees, maps and theorems by Jean-Luc Doumont), is this paragraph on helping stem the flood of emails. Sage advice indeed:
If you are buried under too much incoming email, you may feel helpless about it. Yet, without hoping for a revolution, you can still take concrete steps toward easing the overload. To receive less email, simply send less email - and send better email, too.
So, starting today, think before you send and if it's not required, don't send it.

Is this the next Uber Drone, coming to some skies near you? As the article says, would like to see 1000 hours of safe flight time first and the ability to fly with only two motors by feathering then should there be a failure. Exciting times though - I get a sense of scenes from The Fifth Element coming true (that would be Ruby Rhod first maybe)!!

And the cost of hiring a UAV is being driven down.... Dronebase is your AirBnB of UAV operators. Don't pay over the top and go to one site to find them. The growth has been extremely rapid - see what their investors think. Its a great idea and, well, a very useful resource.

GIS-Geography had a nice geosheets tutorial just before Christmas which is worth a look-in. Geosheets is not a service I had seen before and operates as a plugin for Google Sheets, adding functionality to geocode spreadsheet data and plot on a basemap. Of course ArcGIS Online and, indeed, Google MyMaps. However Geosheets offers you the ability to create within Google Sheets itself using some simple syntax. I wonder if they have enough to survive (don't complete with Google or Esri!) but, in the interim, it's another toolbox for geoenthusiasts.

Keep it simple...
Sage advice from John Lilly:
My big lesson was the importance of a simple message, and saying it the same way over and over. If you’re going to change it, change it in a big way, and make sure everyone knows it’s a change. Otherwise keep it static.
...and that goes for any type of communication. Keep the core message simple to understand because whilst the implications may be profound, your target audience needs to be able to take it in and interpret it unequivocally.

Shapefile or geodatabase?
A nice overview and comparison of the shapefile, personal geodatabase and file geodatabase over at the guys at GIS Geography. Its a good succinct summary and review of the pros and cons. They do note that the file geodatabase is proprietary (to Esri), but not that the shapefile is too. And whilst (quitea while ago) Esri published a whitepaper detailing the specification of the shapefile its worth noting that they have released the API to the file geodatabase as well.

Note to self... duplicating a tab in Firefox
This is one of those actions that is incredibly useful every so often... you have a tab open and you actually want to duplicate (so you have an active copy) and then carry on working with the current tab. Except there is no "duplicate tab" (or clone) option when you right click in the window or on the tab. This is actually one of those Unix-esque type daisy-chaining of functions to achieve the same in result. So... middle clicking on a link will load that link in a new tab (very useful itself). Solution:
middle click on the reload page icon (next to the address bar)
Always easy when you know how!

It's a , stupid!!
Yes, one of the manuscript writing moments where I was using Endnote and wanted to cite a webpage for an organisation. Enter the oranisation name in and the European Geosciences Union gets turned into...
This is one of those annoying diversions where you either go and work and the syntax for citing it or... do it manually.
In this instance I Googled it and found that all that was needed was the humble
