;Is it a real word puzzle?
Who wants to labouriously check if he's double-bluffed and used an actual word puzzle for this comic? :D [[Special:Contributions/162.158.154.181|162.158.154.181]] 17:45, 13 August 2018 (UTC)

"Jeopardy" is misspelled in the description. Can someone who is logged in please fix?
Many of the "clue" words can also be rearranged, anagram-wise, to form new words, e.g., parts ≈ strap. {{unsigned ip|162.158.74.243}}

Most words have 2, 3, 4 or 5 characters. I do not believe, it is a simple crossword puzzle, otherwise he would not fool people. Sebastian --[[Special:Contributions/172.68.110.4|172.68.110.4]] 18:17, 13 August 2018 (UTC)

;Some thoughts:
*Cueball is messing with Megan and not presenting an answer what the "reminiscent of Jeopardy answers" would imply.
*{{w|Lance Ito}} is a judge well known for the O. J. Simpson murder case.
*{{w|Brian Eno}} is an English musician, composer, record producer, singer, writer, and visual artist. Read the Wiki article to learn more.
*No idea what "Ohio's AirAsia Arena" could imply.

::Almost all the words in the alt-text / title-text are open to multiple pronunciations from a phonetic standpoint. Often they're placed next to a word containing the same sound with a different spelling, or the same spelling with a different sound.
::Once again Randall is creeping me out with this, as yesterday I complained about the spelling of "tear" with a comment including this line:
::tire tier tear tear tare tar ... teer?
::Randall so often does comics that feel intimately in touch with what I'm doing or saying the day before that it's almost spooky. If I weren't an outlier in so ''many'' scatter plots I might almost begin to feel "ordinary".

;Moved from the explanation (discussion goes here)
The kind of puzzle that Megan thinks she is solving is called a "Cryptic", which has markedly different rules than ordinary crosswords. If Cueball's statement had been "Part of this aria is an Indian garment" the answer would have been "sari", because a part of the phrase "this aria" is the sequence "sari", which in turn is an Indian garment. Cueball's actual statement contains quite a few familiar cryptic puzzle triggers. The word "composed" can be a hint of a preceding or following anagram, in this case of "this aria" or of "by Brian" or of even longer adjacent strings. Although "opera star" could be a famous singer, say "Caruso", it might also be the name of an opera followed by the name of an astronomical star. "Au pair" could be any of its ordinary meanings, say "nanny", but might also be "earrings" (because AU is the chemical symbol for gold, and a gold pair could be earrings). The word "start" is often a hint to take just the beginning of a word, so "the start" would be "t", or "start of his" would be "h" or "hi". The New York Times runs a cryptic crossword as its "second Sunday puzzle" every other month or so, and there are other regular cryptic crossword venues. In case you are interested, there are various guides on the web for solving cryptics, such as this one at The Atlantic: https://www.theatlantic.com/past/docs/issues/puzzclue.htm. (-- John?)
:I am sure there are many more sources for cryptic crosswords. It is my understanding that it is the common mode of crossword puzzles in Britain. Surely some British papers run them routinely. [[User:Momerath|Momerath]] ([[User talk:Momerath|talk]]) 04:06, 15 August 2018 (UTC)
:This sounds like the most correct explanation to me so far, much moreso than the strictly crossword-based interpretation. I think this ''should'' be in the explanation.

::I've moved this because it's written like a comment (including the sign). And I think at first we should focus on the ''My Hobby'' thing, Cueball is messing with someone. If you're also ''sure'', like Megan is, that there is a puzzle to solve then Cueball is probably messing you too. Nevertheless all mentioned items and persons have to be explained. --[[User:Dgbrt|Dgbrt]] ([[User talk:Dgbrt|talk]]) 09:16, 14 August 2018 (UTC)
:::I think it's a given that Cueball is messing with Megan, and that the focus should be '''why''' Megan thinks this is a word puzzle. The current explanation says the "text contain[s] many words that appear frequently in crossword puzzle answers", which seems an unlikely explanation to me. Surely the trigger shoud be many words and constructions that appear frequently in word puzzle clues (not answers), and I think John gave a good explanation of why this shounds like a word puzzle clue. [[User:Sandor|Sandor]] ([[User talk:Sandor|talk]]) 17:17, 14 August 2018 (UTC)
::: I agree with Sandor. This should be put into the explanation.[[User:Justhalf|Justhalf]] ([[User talk:Justhalf|talk]]) 20:34, 14 August 2018 (UTC)
:: I agree that the explanation as a cryptic puzzle makes much more sense than an explanation that the sentence uses words common in crosswords. Where's the puzzle in saying ''solutions'' to crossword puzzle questions? In general, it also seems a little arrogant to remove someone else's explanation unless it's obviously wrong. If you disagree, just change it to say it's a "possible interpretation". [[Special:Contributions/172.68.47.36|172.68.47.36]] 17:46, 14 August 2018 (UTC)
:: I put it back in the explanation, with only minor tweaks. It's too good to leave just in the comments. [[User:N0lqu|-boB]] ([[User talk:N0lqu|talk]]) 20:37, 14 August 2018 (UTC)
:::Few remarks:
:::*I didn't remove anything, I just moved something to this discussion to be discussed here because "it's written like a comment".
:::*This comic is on the first place a typical [[:Category: My Hobby]] comic. Fooling others is a long term hobby by Randall.
:::*The puzzle (also that from the title text) has no solution.
:::*The title of this comic is "Word Puzzles". Cryptic puzzles as given in the link are much more complex and different to that how Cueball talks.
:::And guesses like "If Cueball's statement had been" or "could be a famous singer" don't explain that much. If this is really a cryptic puzzle I would like to get the path how to solve it and what's the possible solution. I doubt there is any.
:::Nevertheless everyone is welcome to add more interpretations, but please don't write it like a comment. Think about the readers.
:::--[[User:Dgbrt|Dgbrt]] ([[User talk:Dgbrt|talk]]) 20:22, 14 August 2018 (UTC)
::::I liked the explanation as it was, because it was explaining how Megan, and other puzzle solving people, would likely be trying to solve Cueball's fake puzzle, giving examples of the kinds of things they would be looking for. You see Megan fixating on words like "start" and "parts", as if she's treating it like a Cryptic puzzle. Yes, signing it like in the comments isn't right, but the rest of it felt just fine for the explanation section, but best located after the more direct explanations.

Although Randall says he is messing with us, the fact that he is so much cleverer than any of the rest of us means that Cueball's statement might even be a legitimate cryptic clue. --John [[Special:Contributions/108.162.219.214|108.162.219.214]] 18:40, 13 August 2018 (UTC)

When I first read this sentence, I thought he just wanted to be needlessly verbose for a simple joke, like [https://www.youtube.com/watch?v=oE5KkmDAcDs here]. [[User:Fabian42|Fabian42]] ([[User talk:Fabian42|talk]]) 08:16, 14 August 2018 (UTC)

In the explanation, I think there's a misunderstanding of "post-live". Death is "post-life", while "post-live" is the period after an artist stops performing live (in rock conerts, on stage, etc.). The artist may still be alive, and even produce studio albums. So, according to the comic, Brian Eno has stopped performing on-stage, but has still continued to create music (e.g. compose an aria). - Assaf {{unsigned ip|141.101.107.30}}
: My thoughts exactly - post-live does not mean after death! [[User:Ianrbibtitlht|Ianrbibtitlht]] ([[User talk:Ianrbibtitlht|talk]]) 12:44, 14 August 2018 (UTC)
::Thanks for mentioning this. The phrase is still incorrect so I'll do an update. BTW: Is the concert on this album {{w|June 1, 1974}} the last or maybe even the only live performance Eno has done? --[[User:Dgbrt|Dgbrt]] ([[User talk:Dgbrt|talk]]) 13:52, 14 August 2018 (UTC)

I arranged all the important words in the main text on a Scrabble board. The total score of all the letters is 69. The total from my arrangement is 116. {{unsigned|Misterblue28}}

Reminiscent of the alliterations in BoJack Horseman.
:"Are you still looking for a star for your Transgender Teddy Roosevelt Planes Trains and Automobiles reboot, Plans, Trans, A Canal, Panama?"

:"You know the actress Courtney Portnoy? She portrayed the formerly portly consort in the seaport resort. Courtly roles like the formerly portly consort are Courtney Portnoy's forte. This was supposed to be Courtney's crossover coronation. But that's sorta been thwarted unfortunately 'cause Courtney's purportedly falling short of shoring up fourth quadrant support."

:"But Courtney, more importantly, audiences are going to adore your tour de force performance as the forceful denim-clad court reporter in "The Court Reporter Sported Jorts", the jet-setting jort-sporting court reporter story."

Would it make more sense to interpret "Brian Eno's opera star au pair" as "Brian Eno's au pair, who is an opera star" rather than "an au pair to an opera star which belonged to Eno"? It seems to make more sense, and there isn't anything that I can see that necessarily divides "opera star" and "au pair" into two separate clauses (such as "opera star's au pair").[[Special:Contributions/162.158.187.25|162.158.187.25]] 16:44, 14 August 2018 (UTC)

[[559: No Pun Intended]] is related: there too Cueball talks about a hobby where he tries to fool people to think there's some hidden layer under his words. This usually works out better for him than the opposite, [[153: Cryptography]] or [[410: Math Paper]], when tries to fool people that he's giving a serious presentation but it's all just a joke. [[Special:Contributions/162.158.92.154|162.158.92.154]] 08:41, 15 August 2018 (UTC)

Isn't there a page that lists all the comics in the "My Hobby" series? If so, we should add it in a Trivia section and make sure to update it with this comic. [[User:Ianrbibtitlht|Ianrbibtitlht]] ([[User talk:Ianrbibtitlht|talk]]) 13:18, 15 August 2018 (UTC)
: Ok, I see the link to that page was shared in an earlier discussion post, and this comic was added to that page.

:::You're talking about the category "My Hobby" which is always shown at the bottom of the comic page. Your rework is clearer - I just thought the simple word "hobby" for that link would be enough.

I saw this comment on the Guardian's cryptic crossword blog[https://www.theguardian.com/crosswords/crossword-blog/2018/aug/06/crossword-roundup-donald-trump-in-nine-squares#comment-119413228], which makes the point that it contains both the short vowel-heavy words American crosswords are notorious for using ("aria", "Eno", "opera", "era", arguably "au pair") and the common cryptic indicators ("parts of", "composed", "at the start"). In addition I see some semordnilaps ("parts", "Eno", "star", "live era", arguably "opera"[https://en.wikipedia.org/wiki/Sator_Square]) and other anagrammable words ("this"="hits"="shit"="Sith", "Brian"="brain"="bairn"="Rabin", "post"="pots"="opts"="stop"="spot"="tops"). Also "star"+"p"="parts", "star"+"t"="start", "op"+"era"="opera", and "opera" in Spanish sounds like "au pair, ah" at least according to this[https://www.youtube.com/watch?v=-W3Zwi9Otac] pronunciation video. There are many potential wild goose chases here.

:Also ARIA occurs backwards in "au pAIR At the start" and the alt-text's "AIRAsian arena." Not sure if it's necessarily a cryptic, since it could just be wordplay without a definition.[[Special:Contributions/172.69.62.226|172.69.62.226]] 00:13, 11 October 2018 (UTC)

2293: RIP John Conway

2023-03-24T03:43:50Z

CrypticGuide:

{{comic
| number = 2293
| date = April 13, 2020
| title = RIP John Conway
| image = rip_john_conway.gif
| titletext = 1937-2020
}}

==Explanation==

{{w|John Horton Conway|John Conway}}, an English mathematician, passed away of [[:Category:COVID-19|COVID-19]] on April 11, 2020. Two days later, [[Randall]] created this [[:Category:Tribute|memorial comic]]. It is the 6th memorial comic, but it is the first released in almost 5 years, since [[1560: Bubblegum]].

One of Conway's most famous creations was the {{w|cellular automaton}} known as {{w|Conway's Game of Life}}. A cellular automaton is a machine composed of cells, each of which can be in a different state. Every generation, each cell in the automaton may transition to a new state depending on a set of rules. (Conway's work in mathematics was vast and various, but he is perhaps best known in the field for discovering the {{w|surreal numbers}}, which inspired Donald Knuth to write a novel which may have been referenced back in [[505: A Bunch of Rocks]].)

Conway's Game of Life was first popularized to the general public in the form of a game, Life Genesis, bundled into some distributions of Windows 3.1, an operating system from the early-90s that Randall most likely used in his preteen years.

Conway's Game of Life is a 2-state automaton (i.e., every cell can be "alive" or "dead") that is implemented on a two-dimensional grid of cells using the {{w|Moore neighborhood}} - this means that each cell can only be influenced by the eight cells directly surrounding it, both orthogonally and diagonally. The transition rules that Conway used are as follows:

* If an "alive" cell has no live neighbors, or only one live neighbor, it becomes "dead". (This simulates death by isolation).
* If an "alive" cell has four or more live neighbors, it becomes "dead". (This simulates death by overcrowding).
* If a "dead" cell has exactly three live neighbors, it becomes "alive". (This simulates birth).

Despite the simplicity of these three rules, Conway showed that patterns of amazing complexity can nonetheless develop out of simple cell arrangements. Some patterns do not evolve at all ("still lifes"), some enter a cyclic, repeating state ("oscillators"), and some reproduce their own pattern displaced by an offset, resulting in patterns that can move across the grid under their own power ("gliders" and "spaceships"). This last category is of particular interest, as it allows the Game of Life to transmit information from one location to another, allowing for rich, dynamic behavior and even for the creation of computational machines within the automaton itself.

This comic begins with the shape of a stick figure as the starting cell configuration of the Game of Life. The black cells are "alive" and the white cells are "dead". This configuration then evolves via Conway's rules, disintegrating into nothingness except for a five-cell pattern known as a "glider", which ascends up and to the right. This visually suggests an eternal "soul" breaking away as the corporeal body disintegrates. The glider is perhaps the most iconic pattern of the Game of Life, and is often used symbolically to represent the phenomenon of emergence.

Here the topology of the grid on which the cells evolve is not known, the cellular automaton can be run on many topologies, for example you can choose to make cells reappear from the opposite side once they reach an edge (similarly to the behaviour of the well known Pacman). Here once the glider reaches the top right, we know for sure that the actual grid is bigger (since the glider leaves the frame while continuing its pattern), and we are only seeing part of the full grid.

The initial state presented in the comic does actually evolve in that manner, as can be verified by entering the pattern into a cellular automaton simulator such as [http://golly.sourceforge.net/ Golly] or web services such as [https://bitstorm.org/gameoflife/ this one] or [http://catagolue.hatsya.com/object/xkcd_48jsj8gzwe9e/b3s23 that one]. It seems that no one else have created this pattern before. At least, despite discussion in the comments, no one has found anything to show that this is not Randall's own discovery of this pattern.

The title text simply states Conway's birth and death year: 1937-2020.

Conway's Game of Life was previously mentioned in [[696: Strip Games]]. Cellular automata was also referenced in [[505: A Bunch of Rocks]].

This comic is the 18th comic in a row (not counting the [[2288: Collector's Edition|April Fools' comic]]) in a [[:Category:COVID-19|series of comics]] related to the {{w|COVID-19 pandemic}}. Although this comic is, of course, mainly a tribute to John Conway, the fact that he died of COVID-19 in the middle of this long series of coronavirus-related comics by Randall is relevant.

==Transcript==
:[A pixelated image of a stick figure using 21 pixels, could be a pixel Cueball, which waves with one hand up while holding the other hand down. The head consist of 7 pixels, the top row of three having two pixels beneath the two outer pixels, thus having two empty pixels beneath the central pixel. The neck and torso is a typical cross made from six pixels. The two legs are two pixels each shifted left and right of the cross. The arm to the left that waves is two pixels one down and the next back up to the level of the cross central beam. The arm to the right has the first pixel similarly but the second pixel continues one further step down. After less than one second it turns out that the image is animated, with the pixels changing according to the rules of Conway's Game of Life. The figure splits into three groups, two of which dissipates in a similar way at the bottom of the panel. The other becomes a 'glider' and moves off to the top-right corner of the image and out of the frame. The animation then repeats.]
