The grades are available and have been sent to all that so far have requested their grade.

Reminder: the grade is a weighted average of:

• Home Exam 1 25%
• Home Exam 2 25%
• Oral Exam 50%

Each has been given a grade A - F but with small or larger plusses or minuses as to avoid unfair rounding errors.

So the published grade has been determined as to keep rounding errors to a minimum.

Distribution:

A 2

B 5

C 3

D 1

E 0

F 0

Thanks for taking the course - it has been fun :)

Sincerely, Eric

Here is the schedule. Now updated with room number and when you should show up.

The exam will be in room OJD 2269 Seminarrom Python.

Good luck.

Eric

Use the Doodle below for choosing which exam slots that you prefer. There are 12 students taking the oral exam. If you have submitted Home Exam 2 AND not heard from me (or MN) then you have been approved for the exam in that we have gone thru the submission and in the first pass approved those that are to pass. Detailed feedback will come later.

Pick as many or as few time slots that you want. You can add comments, e.g., please before lunch or please after lunch. Note that the date is June 11th, 2019.

I will close the poll June 5th 2019 shortly after noon.

Dear students,

At the previous Exercise Session (April 29), I went over the PCRType in Home Exam 2, as well as how to emulate temporary unavailability using Docker. This is now fully covered by the associated notes and sample Emerald files.

Dear students,

I seem to have forgotten about the Easter break! I will post some notes on the topics I mentioned earlier, but I don't expect you to show up :-) If you do, see you there.

Dear students,

The subject matter for today's exercise session is:

1. Parametric polymorphism in Emerald, or debunking PCRType from Home Exam 2.
2. How to emulate unavailability using Docker.

Dear students,

Emerald does not have bitwise xor and negation built-in. You might want these operators for implementing a hash function in Home Exam 1. Luckily, bitwise negation can be simulated using integer negation and subtraction, and xor can be simulated using bitwsise or, and, and negation.

Here is a sample program that

1. implements both bitwise negation and xor,
2. shows that the (bitwise) negation of 0 is (-1), and vice-versa (recall two's complement arithmetic), and
3. prints out the truth-table for xor.

const xorneg <- object xorneg
  function neg[x : Integer] -> [y : Integer]
    y <- -x - 1
  end neg
  function xor[x : Integer, y : Integer] -> [z : Integer]
    z <- (x | y) & self.neg[(x & y)]
  end xor
  initially
    stdout.putstring["(neg)   0  ~> " || (self...

Dear students,

I have made my Emerald language definition for the LaTeX listings package available alongside other Emerald syntax-highlighting offerings.

See https://github.com/emerald/syntax-highlighting/tree/master/envs/listings.

You can use this to include syntax-highlighted Emerald source code in your report.

Call-by-visit emulation:

   X.f[visit b]

emulated by:

   home <- locate self

   move b to X

   X.f[b, home]

And modifying f:

   op f[arg: T, home: Node]

      ...

      move arg to home

   end f
