Marco Polo is software that you can use to make your laptop “location aware.” You set up a series of predicates based on things like visible wifi networks, ip address, external monitor, usb devices, etc. Marco Polo will evalute each of the predicates and come up with a score that it uses to determine where you are. For example my work desk and my work mobile profiles are very similar, but when I’m not connected to my desktop monitor the mobile profile is ranked slightly higher.
You can preform a bunch of built in actions like changing default printer, changing wallpapers, etc. but the really cool thing is that you can run an arbitrary shell script. When I plug in at work I automatically nfs mount our file server. When I’m at home and my vpn is up, I automatically sshfs mount the fileserver. My environment at home is automatically setup to be the same as my environment at work. It’s cool stuff and worth checking out.
