{{notice|This comic contains just one opinion as interpreted by [[Randall|the comic's author]].
Please take care to not add anything to the main article that might be your own personal political opinion. This is not a rolling-news channel or debating room. |image=warning!!.png|**NB. This warning could remain as long as Harris is a candidate in the election. Once this process concludes, we might need a different warning.}}

On the Monday that this comic was published, US Vice President {{w|Kamala Harris}} became the new presumptive {{w|Democratic_Party_(United_States)|Democratic Party}} nominee for the 2024 presidential election, having received verbal endorsements from a majority of Democratic state delegations; the day before, President {{w|Joe Biden}} had {{w|Withdrawal_of_Joe_Biden_from_the_2024_United_States_presidential_election|suspended his re-election bid}} and endorsed Harris. These major events resulted in Harris replacing Biden as one of the top two candidates for {{w|President of the United States|President}} in the 2024 election.

This comic features a three-way {{w|Venn diagram}} (which [[2721: Euler Diagrams|is also an Euler diagram]]). The three circles represent eligibility for US presidency, ability to do a good job as the US president, and love for Venn diagrams:

# '''Good President:''' The dominant Internet topic of conversation when this comic was published was Harris and people's opinions about her, and [[Randall]] personally thinks she'd be a good president but that he himself would not be.
# '''Eligibility:''' According to Article II of the {{w|US Constitution}}, someone is {{w|President_of_the_United_States#Eligibility|eligible for the presidency}} if they are a natural-born citizen of the United States, are at least 35 years old, and are a resident in the United States for at least 14 years. Both Randall Munroe and Kamala Harris meet these qualifications.
# '''Vocal Venn Diagram-philia:''' Harris' affection for Venn diagrams is something of a meme, and has been used by her in her campaign [https://www.independent.co.uk/news/world/americas/us-politics/kamala-harris-campaign-memes-gen-z-b2583802.html]. Randall is also known for his love of Venn diagrams, which feature heavily on xkcd. Randall especially loves Venn diagrams ABOUT Venn diagrams, like this one.

Part of the humor arises from the contrast of putting on a level playing field three characteristics that range widely from the momentous to the quirky, as well as the implication that Randall and Harris are quite similar in all but one area: Randall's opinion on their fitness to serve as US President.

The diagram does not indicate anyone who Randall would include in the six other areas (categories) of the Venn diagram besides the two in which he listed himself and Harris.

The title text [https://www.youtube.com/watch?v=eWR2uTfrh-k quotes Kamala Harris on her affection for Venn diagrams], and implies that the best way to target Randall with political ads is to mention how amazing Venn diagrams are.

Randall seems to express support for a Democrat Presidential candidate every 8 years, including in a 2016 comic [[I'm With Her]] endorsing {{w|Hillary Clinton}} and in [https://blog.xkcd.com/2008/01/28/obama/ a 2008 blog post] endorsing {{w|Barack Obama}}. In 2032 he will endorse [attention time-travelers/future editors, please edit this part to fill in whoever is running for president, and whether [[1688|the spiders are able to vote]].]

2699: Feature Comparison

This is comparing different remote communication services, including the relatively well-known {{w|Twitter}}, {{w|Discord}}, {{w|Mastodon (software)|Mastodon}}, {{w|Facebook|F(ace)B(ook)}}, {{w|Slack (software)|Slack}}, {{w|Signal (software)|Signal}}, {{w|Internet Relay Chat}} (IRC), {{w|Tumblr}}, {{w|Reddit}}, and mobile telephone {{w|SMS}} text messages.

The less well-known "{{w|Cybiko}}® wireless handheld computer for teens (2000)" was a handheld computer designed for teens and released in 2000, which featured its own two-way radio text messaging system. The Cybiko has two-way communication capabilities along with built-in games and music player capabilities. Additional information about it is available at [http://cultureandcommunication.org/deadmedia/index.php/Cybiko the Dead Media Archive], as the device has not been manufactured since 2003. The chart suggests that the Cybiko has an advantage over all of the other ten communication services listed, as it has all eight of the features listed in the table, whereas none of the other services under consideration have more than five of the features. Of course, purchasing a Cybiko or finding friends who own one can be its own challenge, as device was discontinued nearly 20 years ago.


{{w|Mesh networking}} is the ability for users to have P2P connections, and talk without a centralized server. The Cybiko has this as well as wireless message delivery because it communicates to other devices via radio hence the ability to operate without any internet connectivity at all.

The table appears to have a number of errors. For example, Mastodon doesn't require a central server and doesn't support file transfer. (An earlier version of the comic suggesting there Mastodon has no user-run instances was corrected by [[Randall]] shortly after publication of the original.) IRC does require at least one central server, and doesn't support file transfers without the use of client extensions. Discord, Reddit, and Slack have instances moderated and administered by users, but the corporations behind them "run" their software and control their data storage. Discord previously hosted a video game storefront but doesn't have built-in games within the application itself; meanwhile, Reddit occasionally does. Tumblr and SMS do have a form of group chats.

2604: Frankenstein Captcha

2022-04-09T22:18:17Z

Kainaw: /* Transcript */ It is clearly Pluto. He went to trouble of adding Pluto's heart and Charon.

{{comic
| number = 2604
| date = April 8, 2022
| title = Frankenstein Captcha
| image = frankenstein_captcha.png
| titletext = The distinction between a ship and a boat is a line drawn in water.
}}

==Explanation==
{{incomplete|Created by Rated Argh -Please change this comment when editing this page. Do NOT delete this tag too soon.}}

This comic strip is a play on the meanings (and misunderstanding) of the name "Frankenstein". ''{{w|Frankenstein; or, the Modern Prometheus}}'' is an 1818 novel by Mary Shelley about a medical student named Victor Frankenstein who creates an artificial life-form. The man he creates once describes himself as "the Adam of [Frankenstein's] labour" in the book, and strictly speaking is properly known as "Frankenstein's ''monster''" (or perhaps "creation" or "son"), but is often erroneously called "Frankenstein" himself. This has been fertile ground for many, many debates whether the monster could also properly be called "Frankenstein," either as a family name, an honorific, or simply because it's more recognizable and convenient. Randall has weighed in on the debate himself in a previous comic, [[1589: Frankenstein]].

The CAPTCHA shown in the comic instructs the user to select all tiles containing Frankenstein. The tiles include both a reanimated corpse resembling Frankenstein's monster and a scientist yelling, "It's alive!” who is clearly intended to be Victor Frankenstein. The problem arises from the contrast between various definitions of the term Frankenstein. Going just off the book's text, the monster has no name, so the correct answer to the CAPTCHA is just the left square of the third row.

CAPTCHAs serve a dual purpose: (1) to separate human users from bots by way of intelligent interaction, and (2) to train a neural network, hence the "correct answer" to image recognition CAPTCHAs is not known ahead of time and is merely based on the most commonly-chosen tiles. Users who frequently face CAPTCHAs are familiar with the dilemma of having to choose tiles that they know do not contain the requested object but which they know were likely chosen by previous users, making the CAPTCHA one part object-identification exercise and one part human-psychology exercise. Thus, a user who knows that "Frankenstein" refers only to the scientist would face this CAPTCHA with dread, uttering "Oh No" as they realize that they must select the tiles containing the monster, and possibly not even be allowed to select the tile containing the actual scientist Victor Frankenstein if they want to pass the CAPTCHA.

Alternatively, this comic strip with its "Oh No" caption could be referencing [[1897]], which would imply that someone had actually created a Frankenstein's monster which needs to be located as soon as possible.

Many of the other tiles appear to be pictures of entities that inspire similar pedantry. For example, there is a picture of a turtle (or possibly a tortoise, or a reference to the {{w|Voight-Kampff_machine|Voight-Kampff test}} used in a manner analogous to CAPTCHA), a ship (or possibly a boat), {{w|Link (The Legend of Zelda|Link}} (the name given to each of several protagonists that appear across generations and timelines, throughout the ''{{w|Legend of Zelda}}'' video games, who many erroneously refer to as Zelda), a pond (or possibly a lake, a puddle, or a {{w|mirage}}), a squash or pumpkin (often subject to the ''fruit or vegetable'' debate), an erupting volcano (with lava, or is it magma?), and the planet Pluto (or is it a dwarf planet?). Other tiles seem to be inspired by images that commonly occur in actual captchas, like the STOP sign or the traffic light. However, at least some of these may also be meant to fall into the category of entities that inspire pedantry, for example: because traffic lights can also be called traffic signals or stoplights; many people thinking that the shape of a stop sign is a hexagon, not an octagon; and the definition of a sandwich (previously discussed as a “random semi-ironic obsession” in [[1835]]).

The title text refers to the fact that if you draw a picture of a boat/ship on calm water (a straight line), it is usually assumed to be on a lake or pond and is thus a boat, but if it is on wavy water (as in the comic), it's assumed to be on the sea and is thus a ship{{citation needed}}. The phrase "a line drawn in water" is an idiom for something ephemeral. Ironically, it has persisted for a long time and dates back at least to the early Buddhists. (e.g. [https://suttacentral.net/an3.132/en/sujato?layout=plain&reference=none&notes=asterisk&highlight=false&script=latin| AN 3.132] & [https://suttacentral.net/an7.74/en/sujato?layout=plain&reference=none&notes=asterisk&highlight=false&script=latin| AN 7.74]). The title text is also a pun on the common idiom "drawing a line in the sand."

2459: March 2020

2021-05-06T11:44:16Z

Kainaw: I read this as a direct copy of the 12 Monkeys plot.

{{comic
| number = 2459
| date = May 5, 2021
| title = March 2020
| image = march_2020.png
| titletext = "I've traveled here from the year 2020 to bring you this vaccine!"
}}

==Explanation==
{{incomplete|Created by a TIME TRAVELING VACCINE. Please mention here why this explanation isn't complete. Do NOT delete this tag too soon.}}
This comic is another in a [[:Category:COVID-19|series of comics]] related to the {{w|2019–20 coronavirus outbreak|2020 pandemic}} of the {{w|coronavirus}} {{w|SARS-CoV-2}}, which causes {{w|COVID-19}}, specifically regarding the [[:Category:COVID-19 vaccine|COVID-19 vaccine]].

This comic shows 15 calendars and [[Cueball]] next to them. The first three months on the calendar are January, February and March 2020. It would be expected that the months would increase in order, but the calendar month stays at March 2020 until the final panel of the comic, where it switches to May 2021, the month this comic was released, indicating that Cueball is "stuck" in March 2020 for more than a year. The COVID-19 pandemic reached the United States in March 2020 and Cueball (probably representing [[Randall]]) may feel that he has been unable to move on with life, or that time was at a standstill until he was fully vaccinated. Seems likely that Randall was past the two weeks after his final vaccination when this comic came out. He has made several comics centered around that of being fully vaccinated in the weeks up to this comic. Specifically [[2450: Post Vaccine Social Scheduling]] and [[2454: Fully Vaccinated]] in April.

In the penultimate 2 panels, Cueball is shown getting his two doses of the vaccine, with [[Ponytail]] and [[Hairy]] administering the vaccines. Also these two panels are in March 2020, but in reality they are most likely in March 2021 and April 2021, as there are typically 3-6 weeks between first and second dose depending on the type of vaccine. In the final panel, the calendar has switched to the current month, May 2021, showing that Cueball can now resume life after getting vaccinated, and most likely having passed the two weeks after final shot mark.

The title text refers to films, such as 12 Monkeys, in which someone travels to the future with a sample from the past. It could be based on initial production of COVID vaccines in 2020 or a reference to films in which an earlier "original" version of a virus is necessary to produce a viable vaccine. Mass rollouts of COVID vaccine ramped up significantly starting early in 2021 and are mostly still not universally available to all adult age-groups; or, if they are, this may be straining supply capacity.

Interestingly, there are only 15 panels, so if the 'normal' months increased in sync, it would "only" be March 2021, not May 2021. This may refer to the [https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7641621/ strange distortion of time during the COVID-19 pandemic]. Clearly 17 panels would have made more sense when counting months, but the point here is that time has been at a standstill the last 14 moths from March 2020 to April 2021; how many panels represents those 14 month (14, 12 or 10) is not important. Using 15 panels, makes the first 3 and the last 3 stand out from the 9 in the middle, which makes sense from the flow of the comic.

The title text is also a reference to comic [[630: Time Travel]] which begins with "I have traveled here from the year...", although this has been with the same speed as anyone else has traveled, one second each second.

==Transcript==
:[In a 3 row by 5 column grid of panels, 15 monthly wall calendars are shown. All calendars have a large header with month and year given on two lines. Below this is a black border with 7 white lines, for each day of the week, and below that 5 rows with 7 columns, making all calendars the same, with 35 spaces. Nothing is shown in these grids. Next to each of these calendars are Cueball show. In the first 12 panels, Cueball is standing next to the calendar, in only slightly different poses. The text on the calendars only change in the top row, then it stays the same for the next nine panels:]

:[In the bottom rows first panel the calendar is, as always. to the left, but now Cueball is wearing a mask and sitting on a chair leaning a bit to the left while he is being vaccinated by a masked Ponytail to his right. She is plugin the needle in to his left arm. To the right is a tall but small table with the cup from which she has drawn the vaccine standing next to the lid of the cup.]

Although this time by a masked Hairy, standing to his right. Hairy is also plugin the needle in to his left arm. To the right is a different small table, with only one leg. On it is a cup from which Hairy has drawn the vaccine. Also some other black things are lying on the table, maybe other syringes for administrating the vaccine.]
