Overwriting the .prj file is not generally good advice without knowing exactly what was done to the data before.

comment How to cover a number of points with disks?
+1 for the reference to capacity clustering. I'm sure anything that can be done in VB for Excel can be done just as well with Python in a GIS environment.

comment How to scale with radius attribute
Can you share a sample data: the project and a subset of the points to test? Easier to check the project than to continue guessing. The marker size should be 1.

comment QGIS fTools very slow adding random points?
I assume the world countries layer is pretty complex? I just tried using the Alaska.shp from the QGIS sample data and 500 random points took less than a minute.

comment How to scale with radius attribute
Changing the measurement units does not affect the map units and therefore also won't help to display the symbols in correct size. You should switch to a CRS with metric units and convert the nautical miles to meters. Yes, you can use the measure line tool to check the results.

Could you explain why you are against using size-scale field? It is there exactly for this use case.

This question appears to be off-topic because it is a call for app recommendations.

Please specify exactly the steps you are performing to sample the raster - don't leave anything out.

@AndreJoost I think I sometimes get notifications from threads I haven't commented on ... not sure if that works for everyone though.

and relative paths together with the data on the usb sticks doesn't work? when you prepare the project, did you have the same folder structure?

comment Open QGIS project on different computers
Did you copy the data files on the usb drive as well or are they on network drives? Did you configure relative or absolute paths in the project settings?

comment How to find and replace a singe word in a string?
Well, you are replacing 'Calle ' in 'Calle ' with an empty string ... therefore the result is empty ... Use replace(name, 'Calle ', '') instead.
