::Nah, a +5,+3,+5,+3 seems too basic. Maybe 22 would work, since this is maximum k for which the grid graph P_2 X P_k is a subgraph of the n X n knight graph.

The 'standard' and '2x' sized images had unexpected sizes, so an imagesize parameter has been added to render the image consistently with other comics on this website. See the web [https://web.archive.org/web/*/window_screen.png archive] for more details. --[[User:TheusafBOT|TheusafBOT]] ([[User talk:TheusafBOT|talk]]) 03:15, 7 October 2025 (UTC)&lt;br /&gt;

Is the comic not fitting into the section right on the original xkcd website? Is this some kind of meta joke? [[Special:Contributions/138.67.132.61|138.67.132.61]] 04:10, 7 October 2025 (UTC)&lt;br /&gt;
:This is Randall's mistake. Since comic [[1084: Server Problem#Trivia|1084]] from 2012, comics usually have two versions: normal and double resolution (2x). If you read on a high-DPI screen (like a phone) or zoom in, you'll see a high-resolution version of the comic, but if you read on a desktop or laptop without zooming in, you'll see the normal resolution. In this case, Randall accidentally uploaded the 2x version into ''both'' comics, making the normal one twice as big as it should be. If you zoom in just a tiny bit, it'll look normal again. &amp;lt;del&amp;gt;I'll add this in a Trivia section&amp;lt;/del&amp;gt; &amp;lt;ins&amp;gt;Someone already did&amp;lt;/ins&amp;gt;. --[[User:NeatNit|NeatNit]] ([[User talk:NeatNit|talk]]) 07:35, 7 October 2025 (UTC)&lt;br /&gt;
:I suspect Randall was inspired by the U.S. President's outsized ego insisting he deserves the Nobel Prize for Peace when he hasn't actually solved any international problems at all, and in the view of many has made things much worse.[[Special:Contributions/68.116.0.20|68.116.0.20]] 05:33, 7 October 2025 (UTC)&lt;br /&gt;

&lt;br /&gt;
I suspect all the math could have been avoided if the screen were just carefully laid out on top of the window and cut to a matching shape.  Why trig when you can trace? --[[Special:Contributions/45.143.82.106|45.143.82.106]] 06:53, 7 October 2025 (UTC)&lt;br /&gt;
&lt;br /&gt;
It's easy when building a flat screen to accidentally get the tension wrong on one side and *generate* non-coplanarity--[[Special:Contributions/174.127.176.33|174.127.176.33]] 08:24, 7 October 2025 (UTC)&lt;br /&gt;
&lt;br /&gt;
Is the &amp;quot;overly large image mistake&amp;quot; really a mistake, considering it’s about the &amp;quot;size&amp;quot; of an image displaying on a &amp;quot;screen&amp;quot;? {{unsigned ip|89.91.92.1|08:34, 7 October 2025 (UTC)}}&lt;br /&gt;
:There is the opinion that Randall made a mistake, but because Cueballs sentence just stops at &amp;quot;how well the screen fits... (the window)&amp;quot; and the panel DOES NOT fit it's window, I believe that this is intentional and the punchline of the comic [[Special:Contributions/195.49.224.20|195.49.224.20]] 09:36, 7 October 2025 (UTC)&lt;br /&gt;

Being &amp;quot;old enough&amp;quot; doesn't mean much, I'm afraid. I saw a very young child in a puschair (not sure what age... probably pre-verbal, though she responded to my friendly waggly-wave of fingers with a close enough gesture in return) with a flashy ear-piercing stud the other day, which was probably her mother's choice to impose upon her. (Not quite FGM/circumcision level of parental imposition, but certainly not consensual.) [[Special:Contributions/92.17.62.87|92.17.62.87]] 20:44, 22 September 2025 (UTC)&lt;br /&gt;
:There are some cultures that traditionally pierce the ears within a few days of birth, on the theory that it's more painful when they're older. The American Association of Pediatrics doesn't have a problem with this as long as it's done safely.

[[User:Barmar|Barmar]] ([[User talk:Barmar|talk]]) 20:57, 22 September 2025 (UTC)&lt;br /&gt;

Is there a new long distance boring project that has happened or is being planned that this comic is in reference to? I was hoping there would be some mention on this page?

The piercing is going rather deep into hot stuff, according to the image (do we have estimates?). Being &amp;quot;old enough&amp;quot; might be implying that enough time has passed for the hot stuff to cool down so that it can finally be safely pierced (do we have estimates?). --[[Special:Contributions/88.113.67.59|88.113.67.59]] 05:33, 23 September 2025 (UTC)&lt;br /&gt;
: By my guesstimate, the entry and exit points are about 700 km (435 mi for imperialists) apart and the ring diameter is twice of that. The section of the ring that is subterran could be 10% of the ring's diameter, so it's 140 km or 87 mi and the ring extends into space by about 1260km, smashing nicely all satellites that don't have a near-equatorial orbit. Maybe we could integrate a space elevator into it? Although I doubt that Gospodin P. will allow that project, because it would totally smash their Kola Superdeep record.

The section of the ring that is subterran could be 10% of the ring's diameter, so it's 140 km or 87 mi and the ring extends into space by about 1260km, smashing nicely all satellites that don't have a near-equatorial orbit. Maybe we could integrate a space elevator into it? But I doubt that Gospodin P. will allow that project, because it would totally smash their Kola Superdeep record.
