I have got my BS and master both with honor with good GPAs. But Now I want to know which of these have more importance to US PhD program in Computer engineering.
TOEFL and GRE  or publication records. What I am looking for is some case like this:


T : 107   G : x   p : 0
T : 98    G : x   p : 1


which case has more chance ?


Question: Logging layers openings?
Answer: What you need is to create (if it doesn't exist yet) a startup.py file in the QGIS python folder:


On GNU/Linux: /home/YOUR_USER/.qgis2/python/
On Windows: (User folder)/.qgis2/python/ Not sure about it, please tell me if you find it to update the answer


and write inside that file something like this:

from qgis.core import QgsMapLayerRegistry

def myLog(layers):
  f=open('/tmp/log.txt','a') # Change this path to your own file
  for lyr in layers:
    f.write('Layer added: %s, id: %s, source: %s' % (lyr.name(), lyr.id(), lyr.source()))
  f.close()

QgsMapLayerRegistry.instance().layersAdded.connect(myLog)


Every time you start QGIS, the code is executed, making myLog to listen to any layer opening, as well as to leave some data into /tmp/log.txt Note that the layer id already stores date/time data, but you could also use Python to write such data into the log.txt file.

You would end up with this:



---- EDIT ----

Note: According to the docs, layersAdded is "[...] emitted for layers added to the registry, but not to the legend and canvas." In case that you want to make sure to only add to the log those layers loaded into legend/canvas, you probably would use the legendLayersAdded SIGNAL instead. Just replace the last line of the code snippet above by:

QgsMapLayerRegistry.instance().legendLayersAdded.connect(myLog)
