Please double-check Final Code Walks to make sure (1) the time works for you and (2) we have your name down properly.
At the moment both instructors have open slots, making it feasible to switch slots without negotiating with other pairs. If all slots get filled up, you will have to negotiate with other pairs to swap. Once the negotiation succeeds, send email to the instructor CCing all involved parties.
Cross-section pairs may sign up with either instructor. If both partners are in sections of the same instructor, the two should sign up with their instructor.

The specification of setup in Logical Interactions and Remote Interactions contradicted each other. I have modified the first one to sync them, meaning setup really transmits the public state (JPub) to the player, not just the map.
Thursday, November 9th, 2023 12:42:16pm
Two students reported a gap in the specification.
Your referee should inform all winners first before informing losers. Both inform-steps must proceed in turn order.
Also, some truly clever testers exploit big-nums, which some languages (e.g., Java) can’t handle in their JSON libraries.
Do not supply test cases with big-num ints. See modified specs.

After the 1030am section, a group of students was finally able to explain the misunderstanding behind the many buggy strategy iterators we have seen.
The strategy (chain) pattern—
Here is my version, rewritten in the text book style of Fundamentals I, using the abstraction teach pack:
#; {Strategy PubState -> (U PASS REPLACE [Listof Placement])} ;; legally iterate strategy `s` starting in the (public) state `pk0` (define (iterate-strategy s pk0) #; {[Listof Placement] PubState -> (U PASS REPLACE [Listof Placement])} ;; generate new state until `s` can no longer add placements ;; or acts illegally with respect to the accumulated placements ;; accumulator: legal `placements` between `pk` and `pk0` (define (iterate/accu placements pk) (match (s pk) [(== PASS) (if (empty? placements) PASS placements)] [(== REPLACEMENT) (if (empty? placements) REPLACEMENT placements)] [action (define placements-so-far+ (append placements (list action))) (if (false? (legal pk0 placements-so-far+)) placements (iterate/accu placements-so-far+ (apply-action pk action)))])) (iterate/accu '[] pk0))
As you can see the iterator does not know anything about s; it would be easy to come up with other strategies and iterate those with the same function. (The iterator is a variant of fold.)

should setup be called when the referee resumes a game from a state that was save between two rounds? As specified and properly understood, it seems only needed to launch a game.
Why? Imagine interrupting a game between two rounds. To safeguard the assets of a player, a trusted “referee” should collect them, place somewhere safe, and hand them back out when the game is resumed. After all, you never know when this is going to happen and who may wish to manipulate the assets.

You will receive an email introduceing you to second partner and a assigned code base today.
The on-boarder should conduct an overview code inspection with the on-boardee as soon as feasible. If the latter then thinks that using his/her former code base might be preferable, switch roles and have the on-boardee perform a code walk of the alternative code base.
collect five sample project-design decisions that illustrate why the alternative code base is preferred to the assigned one;
formulate a justification for each sample why the decision of the alternative code base is superior and write a two-line executive summary of this justification;
turn these five problem descriptions into an HTML memo addressed to your section’s instructor;
For the few cross-section pairs, address the memo to both instructors.
send the memo by Saturday 08:00pm, CCing the on-boardee and the tech TA.

DevOps.Com posted this a couple of days ago:
“A survey of 500 developers conducted by the market research firm OnePoll on behalf of Sauce Labs found more than two-thirds (67%) admitted they pushed code %into a production environment without testing, with more than a quarter (28%) %acknowledging they do so on a regular basis.
More troubling still, 60% also admitted using untested code generated by % ChatGPT, with more than a quarter (26%) doing so regularly.
More than two-thirds of developers have also merged their own pull requests without a review, with 28% confessing they do so often or very often.”

as one’s own." —
When we request test cases from you and you turn in the sample test cases that we provide, you plagiarize. If you would like to know where plagiarists end up in their professional lives, revisit General and scroll to the bottom of the page.

The participants of these code walks will get full-fledged feedback but the grades will not count toward the final grade.
You may wish to take a second look at the course web site concerning how to present and to work as panelists. The site also provides hints as to how we evaluate your performance as panelists or presenters.

A couple of students pointed out during my office hours that my API wish for a function that “determin[es] all those places where a specific tile can be inserted so that it fits according to the matching rules of The Q Game” breaks the design guidelines spelled out in the first few lectures.
Correct!
I added this wish to 2 —
"map"
(provide (contract-out [find-candidates ;; where can the given tile extend this map (->* (map? tile?) (#:rule fit-into-spot/c) (set/c candidate?))]))
(define fit-into-spot/c (-> tile? [option tile?] [option tile?] [option tile?] [option tile?] boolean?))
"q-rule"
(provide (contract-out #; (q-fits tile left right up down) ;; does `tile` fit into the space adjacent to the four neighbors (if any) [q-fits fit-into-spot/c]))

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.

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.)

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.
/course/cs4500f23/bin/check-program-A silly-monkey
Or you can add /course/cs4500f23/bin to your path and run the program like any ordinary shell command.
