Before next class:

Setting up a Repository

  1. Find an SSH client (PuTTY or Terminal or otherwise).
  2. Log in to thing-04.cs.uwec.edu. Or 05 or 06.
  3. Complete the steps shown in the following videos, using https://bitbucket.org/twodee/cs330_2016a as the base repository. (Feel free to watch the videos at faster speeds—I do.)


Welcome to CS 330: Programming Languages! Let’s start with some introductions. I’ll tell you about me and the class. Please tell me the following about you:

  1. Your name
  2. If I haven’t had you in class before, where are you from?
  3. You are commissioned to write a book. What would it be on?

As I get older, I feel less and less like I have any important knowledge to share. Instead, I understand that my role as a teacher is to guide you into danger and then pretend to sprain my ankle. I am not gone, but my role is less direct. At this point, you take over as leader and must construct your own knowledge through first-hand experience. So, expect lots of in-class activities and homework and few slides.

Speaking of in-class activity, let’s do one. Think for a moment about this question:

Why do you think we have this course CS 330: Programming Languages in the curriculum? Write down 3+ reasons. Write them down.

Next question, this time with a partner:

Pick an audience. In one sentence to this audience, what is a programming language? Write it down. Argue about it. Nitpick. Finesse.

For the rest our time, we’ll discuss the shell. It’s the “backstage” of your computer, where the lights are dim and the doors aren’t labeled. What’s something you might want to do at the shell? How can you do it?
