From the first day of the semester forward we expect students (you) to visit this page once per 24 hours.

Michael pointed out that I supported the wrong replies on Pizza. (I don’t like this thing.)
To make up for it, I added two more tests. See The Q Game.

The somewhat complicated holiday/due-date schedule this semester means that we
run 2 —
Also see the updates to the Sunday post below and the The Q Game rules on fitting a tile to a map.
UPDATE I have added two test cases that illustrate tile placements.

I have chosen Racket to make the code (almost) equally (in)comprehensible to the entire class. If you do have vague memories of Fundamentals I, some of the code may ring a bell because BSL/ISL are related to, but are not, Racket.

We have inspected the submitted questions concerning the The Q Game game. As of now, the page is revised in two ways: strike-outs delete words from the rules that might introduce ambiguities, purple words are new additions. (No page changes in any other way.)
Working through examples in public (say piazza) is inappropriate. It’s as if friends working for Amazon and Google, respectively, jointly worked out examples of how to run cloud services.
If you think you can demonstrate another ambiguity with two non-trivial interpretation, contact the instructors.

Concerning B —
As we found out during the first week, the VDI machines no longer exit and the
Linux machines lack monitors. Programs in some of the chosen languages will look
for a monitor if the language uses GUI libraries—
$ xvfb-run ./xgui < ForStudents/0-in.json
This will essentially create a mock display for your program on which it can “paint” the desired shapes. (Our test harness will evaluate your programs in such a manner.)

In preparation for this afternoon’s or tomorrow’s lecture, you may wish to read The Labyrinth Game, which is the board game that brought our company some luck last year.

As mentioned, the design recipe generalizes to almost all tasks in our world (and indeed to many tasks in life .. Fundamentals I used to assign an essay on this point).
ssh into login-students (or another Linux box);
git-clone your “fuzzy elephant” repo to login-students;
navigate (cd) into your “lazy flea"" repo;
make sure A exists and navigate there;
run make if you have a Makefile;
check the executable bit of xjson;
run ./xjson and feed it some JSON value; and
make sure the output looks right.
In years past, we expected students to figure out this checklist and run through it. This year, we provide a script in /course/cs4500f23/bin that implements the checklist and runs your xjson (mostly) how our test framework runs it.
Or you can add /course/cs4500f23/bin to your path and run the program like any ordinary shell command.
