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.

Get ahead in QGIS ...
I've already blogged about Steve Bernard's excellent YouTube Channel on QGIS, well to continue in that vein, here's a link to a series of free (and paid for) courses in QGIS over at GeoAcademy. I cant vouch for the courses themselves, but it's great to see such variety springing up. QGIS is my goto for geoprocessing on a daily basis...

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... Union 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 , at the end of the author field. It's always easy when you know how!
