I finally got my copy of Learning Gnu Emacs back from a friend. I thought I had finished it but there’s a few chapter’s in there that I actually haven’t read.
Something new I learned (and I’m always learning something new despite two-years of near daily use) is the -u flag which allows you to run another user’s .emacs file on a shared system.

While this is great for it’s intended purpose (for example on a shared dev box at work or while pair-programming on a coworker’s machine) I find it also rocks when you need to su to root. Instead of momentarily putting up with plain old vanilla emacs you can load up your personal settings. It’s like going to a friends house and bringing your old lazy boy and direct tv with you (not that I own a TV). Awesome sauce.
