EBoard 03: Images and Decomposition

Getting started

• Grab a card. It will have a computer name and location.
• Drop the card in the jar.
• Navigate to the computer.
• If you are first, log in.
• When both partners arrive, introduce yourselves.
• I think that’s it, but you can start the lab once both people arrive.

Approximate overview

• Administrative stuff, including attendance [10 min]
• Q&A [10 min]
• Lab [60 min]

Administrative stuff

Introductory Notes

• Hi, I’m still Sam (or SamR). Our class mentor is still Eamon Worden. We have a new class mentor, too.
• Fill out the mentor session form on Teams.
• I’m still working on getting our site up to snuff. Expect further changes.

Attendance

• When you are called upon, say your name and something interesting about your partner. (No chatting now.)

Upcoming activities

Guidelines

• Don’t worry, there will be a lot of token opportunities.
• You can earn “tokens” (more info follows) for attending designated academic events or supporting your classmates in their pursuits.
• Attend (or watch recording within a day or so) and record a one-paragraph reflection asap afterwards.
• Only those activities I list count.
  • But you can suggest others.
• Links should appear in the Announcements channel on MS Teams.
• Unless otherwise specified, these each earn one token.

Events

• First Scholars’ Convocation, 11 am, Thursday, September 2.
  • Why you should attend Scholars’ Convocation
• Grinnellephantitis the weekend of Sep 11/12. 60 minutes suffices.

Upcoming work

• Mini Project 1 due next Thursday at 10:30 p.m.
  • All large projects will generally be due at 10:30 p.m.
• Read things in preparation for the fouroth day of class and report on those things
  • You’ll find the readings in the schedule
  • Reading responses are generally due in the early evening (8:00 p.m.) so that I can review them before class.
• Finish the lab writeup from today’s class
  • Ideally, you’ll get lab writeups done in class.
  • Otherwise, they are due immediately before the next class.

Q&A

I’ll try to reserve time for questions at the start of each class.

Do we have to do the stupid “draw a card” exercise at the start of each class period?

Yes. You’ll get to meet new people that way and practice working with others.

How do I connect to these computers remotely?

https://remote.cs.grinnell.edu

Yes, you have to use Duo.

Sometimes it takes two or three tries.

Can I work on my personal computer instead of remote logging in?

Certainly.

But you will need to install the CSC-151 stuff.

Debrief on Friday’s exercises

This debrief has been moved to Friday.

• Important to remember: Things will go wrong. It’s funny when they do.

Lab

Draw party people visiting a cottage who then push over dominoes while the sun explodes into triangles. (or something like that)

If you finish early, start working on the homework. Each person will turn in his/her/hir/zir/their/its own homework assignent.

Debrief

• You need to install the csc151 library the first time you work with our course materials.
  • If you type a space before the https, you’ll get a weird error message.
• Work together on each problem! If I see you working separately, I may confiscate and defenstrate your computer.
• You will, on occasion, see leftovers in the labs from when we were online. E.g., “Contact the lab staff in the Teams channel.”
• You can (start to) format your code for readability.
  • Each parameter to a procedure could/should be on a separate line, at least if the procedure call takes up a lot of horizontal space.
