Academic honesty, revisited

A bad suggestion: Use thumb screws to convince those who did not sign the second entry to tell you more.

A good suggestion: Provide a leniency clause: Students can tell you that they misunderstood the academic honesty policies and request that you just not count the exam. They will receive a zero, but can replace it with their final exam grade.

A good suggestion: Provide those who felt unable to sign with a way to report more details anonymously.

The result of the second suggestion: “I overheard someone talking on the phone about problems on the exam.” “I saw someone talking to one of the evening tutors about problems on the exam.”

Code formatting

What I’d often receive.

(define irgb-weighted-average
  (lambda (weight color)
    (irgb(/(+(*(irgb-red color)weight)(irgb-green color)(irgb-blue color))(+ weight 2))
    (/(+(*(irgb-green color) weight)(irgb-red color)(irgb-blue color))(+ weight 2))
    (/(+(*(irgb-blue color) weight)(irgb-green color)(irgb-red color))(+ weight 2)))))

What I’d like

(define irgb-weighted-average
  (lambda (weight color)
    (irgb (/ (+ (* (irgb-red color) weight) (irgb-green color) (irgb-blue color)) 
             (+ weight 2))
          (/ (+ (* (irgb-green color) weight) (irgb-red color) (irgb-blue color))

Sam goes off on storytelling tangents. But at least they are relevant.

Class 12 (Friday, 10 February 2017)

News / Etc.

• Continue partners! You know the drill.
• I distributed grades yesterday (although with the wrong class listed).
• Only HW1 has been graded. A “check” (the default grade) is worth about 85 points. I think that’s stated somewhere in my policies. (If about 1/4 of your grades are “plus”, you usually have a HW score in the A range.)
• You have all earned five points of extra credit on the exam for corrections. Congratulations! Of course, Titus may never let me write exam problems again. I still appreciate additional corrections, but they will not garner you extra points.
• I think I’ve responded to every prologue I’ve received (as of 10pm Thursday night). If you filled out the prologue before then, and haven’t heard from me, let me know.
• Many of you wrote “Stop when I get stuck for more than a few minutes” in response to “What should you do to be successful”. Note that at that point, you should send me an email message explaining what you are stuck on.
• I was glad to see so many of you (or what seemed to be so many of you) at yesterday’s depressing convocation.

Reminders

• Ask questions via email! I’m always happy to (try to) answer questions via email. There is no need to apologize when sending me questions. If I take too long to answer, send another email (or even text, if it’s a reasonable hour).

Class 11 (Wednesday, 8 February 2017)

News / Etc.

• New partners! You know the drill.
• Please restore my faith in self-gov: Someone volunteer to be the note taker for this class.
• I will be distributing grade records via email tonight
  • I try to keep you posted on what info we have.
  • The computed grade may be lower than you expect. Don’t worry! We don’t have enough information for a real grade computation.
  • If you would prefer that I not send your grades via email, send me a message (via text or in person, if you’d like), and I’ll remove you from my list. You can then get grades from me in other ways.

Upcoming quiz

• Sectioning
• Lambda expressions
• Input and output
• Types
• And all past things
• Not documenting procedures

Doing work on your own laptop or workstation

Particularly with an exam released, some of you will prefer to work places other than MathLAN.

• Approach one: Virtual machine. In this model, you are running a Linux workstation (like those in MathLAN) on your own computer. It will, of course, be slower than your computer. It requires about 8 GB of disk space and 1 or 2 GB of RAM. Details at Reference -> VM.
• Approach two: Connect to MathLAN via ssh. I do this on the Mac regularly. Details at Reference -> Remote.
• Approach three: Work on your program away from DrRacket, and send it to MathLAN when you want to do testing. (You can email yourself, or learn fancier approaches.)
• You can come visit me during office hours for help with either approach.

Notes from our graders

• Please follow the subject conventions for your email; it makes it much easier for us to figure out what you’ve submitted.
  • CSC 151.01 Writeup for Class 9 (Samuel A. Rebelsky and Titus Klinge).
• Please carbon-copy your partner so that they have a record. They may not realize it now, but they’ll appreciate it later.
• Make sure to format your code correctly. Remember that Ctrl

  -I is your friend.

• If you make a prediction, and it turns out to be wrong, you should make a note as to what you learned.
• Nest functions! It’s much easier to write (image-show (color-swatch "blue")) than it is to record the value returned by color-swatch and then type (image-show that-number).

Exam 1 distributed

Class 10 (Tuesday, 7 February 2017)

News / Etc.

• Continue partners and positions!
• Exam 1 will be distributed on Wednesday.
• I really do think that you are best served by working in the CS labs; you have people to help you and talk to. However, if you want to work on your own, it doesn’t work to download DrRacket (unless you run Linux). You either need to download a virtual machine (more on that soon) or connect remotely to MathLAN. You can find information under Reference -> Remote.
• Remember: If you want to look at the eboard “in progress”, replace the .html at the end with .md.

Class 9 (Monday, 6 February 2017)

News / Etc.

• New partners!
• Quiz 1 returned.
  • Note that (irgb-lighter c1) does not modify c1. Instead, it returns a new color.
  • That should not be surprising. You would not expect (square x) to change x.
  • Some of you missed that since the result of compose is a procedure, it implicitly has a parameter. For example, we would describe the result of (define irgbll (compose irgb-lighter irgb-lighter)) as “A procedure, (irgbll color), that computes (irgb-lighter (irgb-lighter color)).
  • That means that the solution to problem 1 should have been something of the form (define myfun (compose ....)).
• Our graders’ account got locked last night. (Even I don’t have access right now.) I’m not sure where we stand in grading.
• Exam 1 will be distributed on Wednesday.
