Disable PDFs in Safari

Some consider Safari a very poor PDF reader (myself included).

An easy way to disable Safari as a PDF  reader is the following command executed in a terminal window:

defaults write WebKitOmitPDFSupport -bool YES

I bought a GT-740FL GPS logger to use when running races that disallow GPS devices with displays. This device has no read out, is motion activated and so can be left on for a couple of days.

It only comes with Windows drivers (not tested) and a dreadful manual. Many of the links on the manufacturer’s website are broken. (You may be wondering why I bought it – I read a couple of good reviews online.)

Getting the logs off are quite easy with the right software.

I am using myTracks and Trailrunner

myTracks I use to copy off the GPS logs and I use Trailrunner to log my runs etc.

We see below the main page for myTracks

myTracks main screen









myTracks preferences tab



We now go to preferences.








myTracks preferences main



The first page lands us on General, from here switch to GPS Devices





myTracks preferences default




Once here click on Start GPS Logger Assistant

The GPS Logger Assistant lists all available devices, I filtered it on my device



Screen Shot 2013-11-11 at 18.09.40



Here we see the device is listed as a Canmore GT-740FL

The device once detected will return with the following defaults, with one exception, the baud rate at the bottom is set to 0. I changed this to the correct baud rate of 4800, this will allow the device to be used as a live GPS device and provide live tracking on myTracks (under the view menu)


I have got live tracking working on Fedora but have not found software that will download the tracks from the device.



Helpful UNIX commands

Strip spaces from file names

find -name ‘* *’ -type f | sort | while read FILE; do NEWFILE=`dirname “${FILE}”`/`basename “${FILE}” | sed ‘s/ /_/g;’`; mv “${FILE}” “${NEWFILE}”;done


Delete files with a specific string in their name:

find . -name “*conflict*” -exec mv {} rm -f \;

This will find files with conflict in their name and delete them. You may want to run it without the rm -f first to check to see what it will delete.
