Finder Shared sidebar with my Raspberry Pi 'ix' listed

Reading the chapter on sharing folders from other computers from Raspberry Pi Networking Cookbook this morning, I decided to do the opposite: share my Raspberry Pi over my local network with my Mac. Henrik Jachobsen has some easy-to-follow instructions, and there it is, my Raspberry Pi! (I named it Ix as an homage to Ford Prefect of The Hitchhiker’s Guide to the Galaxy.) I followed the instructions exactly, except that I used Emacs, of course, and added Samba to the list of software I’ve installed on my Raspberry Pi. Did I mention that I have a list of software I’ve installed on my Raspberry Pi?
