* The subject matter of the class
* The organization of the class
* The parts of a compiler

Welcome to Compilers

* What is a compiler?
  + MF: A program that translates code into a "lower
    level" format.  Friendlier to machines, less 
    friendly to normal people.
  + NG: Error checking going on.
  + EA: May also improve the code.
* What is a non-CS compiler?
  + AH: A person who takes a group of things and makes
    them into a single entity.a
* Differences?
  + EB: Translates many programs into one language.

Why are you studying compilers?

* JK: Its fun and interesting.  It's important to all
  software.
* AP and EB: Trusts the advice of those older and 
  (hopefully) wiser.
* EA: Seems to combine love of OS and Architecture.
* Anonymous: Required for the major
* DB: Hopes will study virtual machines

Why CS362 or CS223?
* programming project

Why CS362?
* One of the best intersections of theory and practice.a
* Learning how a compiler works imporves your code
* Learn more about architectural issues and think more
  closely about what underlies our code
* "Any large project includes its own programming language".
  + Now many languages touted as "easy to add to your large
    project": VB, LISP/Scheme, JavaScript, Tcl, ...

How should we study compilers?
* Build a compiler
* Read some compilers
* Study the theory 

Time for Boring Administrivia
* Some slippage on due dates
* Syllabus on Web is wrong
* You're dealing with experimental software
* It should be a fun class
* Grading: Project 40%, Homework: 20%, Presentation: 10%,
  Final + other exams?: 30%.
* Sam's nasty grading theory: correct is B.
* Sam's nice grading theory: show up to 90%+ classes,
  participate, do most of the work, don't make things bad
  for your group members: No less than B-.
* Don't cheat!
