Preliminaries
News / Etc.
- My wife is nearing the end, so I probably won’t be in class for the
few sessions. I’m sorry, but (a) I want to spend as much time as
possible with her and (b) it seems that I often need to meet with
people during our class times (doctors, in particular, like to
round during our morning classes). There will be awesome folks
here to substitute. I’ll also keep working behind the scenes on
labs and assignments and answering questions.
- I am happy to try to schedule quick Teams meetings, as long as you
understand that I may have to back out. Send me times that you would
be available to meet.
- SoLA 1 should be posted today (as a few separate LAs).
- I’ve done my best to put the questions from your surveys on the
course syllabus page.
Upcoming work
- Readings due Wednesday night
- Submit reading responses for class 5 by 10:30 pm on Wednesday
- Submit today’s lab by 10:30 pm on Wednesday (but preferably at the end of class today)
- Labs will remain “Do as much as you can during class.”
- You may find it useful to complete labs outside of class because
they will contribute to LAs.
- Complete mini-project 1 by 10:30 p.m. on Thursday, 2024-09-12
- Submit Post-reflection for MP01 by 10:30 p.m. on Friday, 2024-09-13.
- Submit SoLA 1 by 10:30 p.m. on Monday, 2024-09-16.

Notes from Surveys
Work due
- I try to make the eboard the definitive list of work due.
- The schedule should also list most/all things.
- Gradescope should have most things due (although it does not
specify readings), but it can be hard to navigate.
- Feel free to ask if you’re not sure.
Collaboration
- About 1/3 of Mini-projects will probably be group mini-projects.
- You should feel free to talk to people about mini-projects. You can
even help someone debug their mini-project. But I had enough instances
of copying recently that I’d prefer that you not share code with someone
so that they can learn from it.
- Please don’t forget to cite!
- You should feel free to talk about reading problems with others.
Ways to get help from Sam (once things settle down) (in preference order)
- For questions that may apply to multiple people
- Ask in the reading response (assuming it’s relevant)
- Ask at the start of class
- Ask in the Q&A channel on Teams
- For individual questions
- DM me
- Set up an appointment
- Wander by during office hours and hope that I don’t have an
appointment
- Catch me after class
- Text me
- Call me
Other resources
- Class mentors (but only during class time and mentor sessions)
- Do not send your mentors questions
- Do not interrupt your mentors if you see them doing their own
work in these classrooms
- Evening tutors (although not for LAs)
- I think that this semester’s evening tutors have all taken
CSC-207, although not this version
- Each other and other students (although not for LAs)
- “Other students” will normally be “classmates”
- Upper-level CS students are also often willing to help
- Other faculty
- We also have individual tutors available for students who request
them (at least for the time being; the College has been cutting
funding)
- Academic advising can also help with individual study skills
- Sarah Dahlby Albright, our Peer Education Coordinator, can talk
with you about CS-related study skills
Questions
Questions on MP1
I’ve put these at the end of the mini-project.
Questions on Maven
Can you explain a bit more about the reasons for the steps in Maven?
Big picture: We want to be able to type commands to accomplish the core tasks related to a project, and do so the same way for each project. These tasks are (a) compiling the code (which we often do to find some syntax errors), testing the code (which we often do to find some implementation issues), packaging the code (which makes it ready for others), style checking (because we want good style), and running the code.
Almost everything else in the reading is how to set up the Maven configuration file, called pom.xml, to tell it what we want done for each of those steps.
Questions on the readings
Why would you choose to make your own hashCode method rather than relying on the built-in one?
Because the built-in one tries to give a different hash code to each object, even if two objects are conceptually equal. For example, if I define v1 as new Vec2D(0,1) and v2 as new Vec2D(0,1), those two objects will likely have different hash codes.
Labs
The person closer to the board is A. The person further from the board
is B.
You will not be submitting code. Rather, I ask you to reflect on three
important things you learned.
