Preliminaries

Admin

• Yes, there were some interesting Git issues. And we'll learn a bit from looking at them.
• I'd encourage you to attend Friday's CS table.
• Given how my semester has started, it seems unlikely that I'll be able to get readings done for very many classes.
  • But I will try to set up some appropriate lab experiences.
• First- and Second-year students: The TC Corps is recruiting! Ask one of the TCCs (Christine, Hannah, Tyler, and Sydney, I think).
• Assignments:
  • Assignment 3: PsAIF/R
  • Read something on the Web about Processing (image-making, Java-like language developed at MIT Media lab by Casey Reas used by many artists

Fun with Git and GitHub

• Don't do git add . BECAUSE YOU'LL POLLUTE THE REPO WITH JUNK
• Getting out of vim: Use :wq or ZZ
• Or get used to git commit -m "MESSAGE"
• If a pull is going to overwrite, git won't let you do it. So do a git commit before doing the git pull.

Project overview

• Let's build an ecosystem for doing math over (abstract) images
• Tool for artistic exploration
• Domain for giving problem-solving challenges
• Model: Numbers from -1 .. 1
• Right now, just greyscale

PsAiF/R

Primary Scheme procedures

Building image functions

Lab

Add the following line to your .bashrc. (You can edit it with gedit.)

export PATH=/opt/racket/bin:$PATH

then see if things work
