We use an application called IntraMaps Roam.  Our guys go out in the field, mark up their maps with GPS points, and then bring them back to the office.  They will copy their shapefiles to the server and the script will combine them at night.  The next morning they will download the new maps.  How can I accomplish this task?
What are useful websites for scouting GIS related jobs?
I remember reading a while back about arithmetics with only a single operator that did all the work of the familiar $+ - \times /$ operators. If there is such a thing, could someone point me to it?  As background: I have a side project where I'm playing with neural nets and genetic search algorithms. Right now it's the good old kind, with matrix multiplication and addition. I thought it would be interesting to implement a sort of neural network that used a combined or "all in one" operator.  I've googled like heck and can't pick up the trail of where I thought I saw that before.  Is there study in that area, or am I mis-remembering, or worse, just making it up? I'd appreciate any pointers.
