FreeBSD - Linux C Based Program to Read a Serial Port

Back in 2007 or so I wrote a C program to read my TP-200 serial port based GPS unit.  I was supprised to find that in 2012, the same program would compile on a Raspberry Pi Linux environment!  Go POSIX programming.

Attached is the C code file and my Makefile I use to compile it.  Use at your own risk.  It works for me, but maybe not you?  To use it, I just run  ./gps > gps_data_file-20121121.txt  and a number of lines will be written to the file each second.

Displaying iPhone Photographs in Quantum GIS

I have been playing with the Quantum GIS software and using it to record some botanical field information I have been collecting.  After I had played around with the PHP scripts on this page:  http://www.bdug.org.au/node/193  I thought it would be interesting to see a visual representation of where the photos had been taken, much like people had done in Google Earth etc.  I could also use it to see what photographs I had taken with the iPhone out on my survey site.
