Admin:
* Exam stuff!
* EC for attending the G-tones concert that may be Monday in the study
  break at the library.

Overview:
* The subject matter of the course.
* Course evaluation.
* Final thoughts.

What one might learn in 151

The Scheme Programming Language
* How to name things
  define, let
* How to define procedures
* How to apply procedures
* Conditionals
* How to write recursive procedures
* Interpreting errors
* Check your parens
* Ways to organize data: Trees, Lists, Vectors, Files
  * And procedures to deal with each
* The random procedure
* throw
* Booleans
* Function composition and other higher-order techniques (left-section, map,
  etc.)

Programming Images
* The GIMP
* Creating images with region.compute-pixels!
* Manipulating existing iamges with image.map
* You often need Math to solve graphical problems
* How images are stored
* RGB colors and techniques for transofrmig them
* Color theory
* A bit of design
* Scaling

Computer Science
* The basic idea: CS is the study of algorithms and data
  * Algorithm: Instructions for doing something (usually on the computer)
* Key techniques in computer science
  * Recursion
  * Divide-and-conquer solutions
* Great ideas in CS
  * Sorting
  * Searching
* An algorithm is more than code: Documentation is equally important
* Need to think formally about problems
  * Preconditions
    * Precondition checking
  * Postconditions
* Interpreting errors
* You often need Math to solve interesting problems
* The benefits of randomness
* How some things are represented internally (ASCII, lists, trees, etc.)
* Ways to understand algorithms and procedures other people have written
* Also looking at efficiency
* And correctness

Computer Science is the Study of Problem Solving
* Break large problems down into smaller parts
* Sometimes you hit a brick wall (or it hits you)
  * Get help
  * Work with others
* Interpreting errors

More General Skills
* Group work skills
* Bullshit on your feet
  * It's okay to say "I don't know" (but not always)a
  * It's okay to try, even if you might fail
* Have fun!
* Support each other
* Interpreting errors
* Spelling is optionaql
* "Um" is the default answer
* Computers are sentient and malicious
