  [Only counts if you are new to Dag.]

The Linux Philosophy
* Free and open souce = Happy
* There's a list of rules that make things Unixy and that can be applied
  to a lot of programs
  * Rule of silence: Don't clutter your output.
  * Rule of clarity: Clear rather than senseless (even at the cost of
    speed)
  * Rule of simplicity: Make it simple
  * Rule of UM: Unix Master (or should that be Master Unix?  Perhaps
    we're using reverse-polish notation.)
* A unique culture: (Oh my god!  There's culture in programming!)
  (More that it's survived for so long.) (And it's fun to study
  primitive cultures.)

Emacs Basics
* It's a text editor
* With lots and lots (and lots and lots)^n options
* It's more than a text editor
  * It can be an email reader
  * It can be a Web browser
  * It can make your lunch (well, maybe not, except at MIT)
Lab

Creating a file from multiple files

* cat file1 file2 file3 > result
* In this case
  cat /home/rebelsky/share/linux/humanfac.txt /home/rebelsky/share/linux/sciencefac.txt /home/rebelsky/share/linux/socialfac.txt > faculty.txt
* or
  cat ~rebelsky/share/linux/*fac.txt > faculty.txt
