<br />
This panel imagines which mathematical symbols would be good in a fight if they were made corporeal in two (or three) dimensions. Generally, objects with longer reach and pointier ends wind up on the "more dangerous" side of the scale, and symbols with less reach and more curves tend towards the left side. <br />
<br />
The comic invokes [[wikipedia:surreal humour|surreal humour]] by suggesting that mathematical symbols could be handled as physical objects in the real world. Another component of the humor is the implication that it is useful to prepare to use mathematical symbols in a fight, even though mathematicians, who use mathematical symbols, are not known for fighting{{Citation needed}}.<br />
<br />
A straight line is farthest to the "more dangerous" side, which could possibly be a reference to the dangers posed by lines in "Flatland", where the points, because they were one-dimensional, were very dangerous. However, taking a more literal view of the drawings, the straight line does not appear to be any thicker or thinner, or pointer, than any of the other lines. <br />

Is it dark mode as in low light UI or dark mode as in depressing? Or both [[Special:Contributions/198.41.238.106|198.41.238.106]] 21:24, 5 August 2020 (UTC)<br />
<br />
I think the title text is using the term "dark mode" not in the sense of UI design but rather that COVID-19 is "dark" and if the app were to have a mode that did what other apps did and gave notifications for potential exposures (bad news) that would be a "dark mode." I have refrained from putting this in the explanation for now as I am curious if there are other interpretations.[[User:Nk1406|Nk1406]] ([[User talk:Nk1406|talk]]) 21:27, 5 August 2020 (UTC)<br />

<br />
During the coronavirus pandemic, several apps were developed to implement {{w|digital contact tracing}} by using one's location along with the location of others, or locationless device proximity detection, to notify someone if they had been potentially exposed to COVID-19. This normally only works in retrospect, as infected people are isolated, and the contacts notified after the positive test result. In this comic, a different type of app has been developed. Instead of notifying someone if they have been exposed to someone with COVID-19, the app produces notifications if they have been exposed to someone who has '''not''' tested positive. (Perhaps it also notifies the user if they have been exposed to a person who has tested positive, but if this is the case, it hasn't happened to the user in question yet.) This is much less useful because it is not possible to tell whether anyone has actually been near anyone who was infected, but rather annoys the user with excessive notifications. Also, being exposed to someone who has not tested positive is not good news, because it is still possible that the person might have COVID-19; it is simply less bad than being exposed to someone who has tested positive, but still worse than not being exposed to anyone. <br />
<br />
Socially and psychologically, people being close to each other normally is a positive behavior. For a stereotypical human, it could be considered a sad sign of our times if you needed an app to tell you whether you did right in social interactions and compliment you. <br />
<br />
It is unclear whether this app genuinely hacks into strangers' medical records to identify whether they have been tested for Covid-19 - normally considered a significant privacy violation and a breach of medical and informatic laws - or whether it just indicates that the person you're coming into contact with isn't currently in a healthcare facility having a test taken (with the proviso in the terms and conditions that it must not be used in a healthcare facility). Patient's medical histories can be shared with public health professionals to manage outbreaks, but only in tightly regulated ways to protect privacy of patients.<br />
<br />
Alternatively, this app is using self-reported data (as other contact tracing apps do) about positive cases, and identifying whether the people near you are in that database.<br />

{{w|Light-on-dark color scheme| Dark mode}} is a common feature in apps which allows users the options to have a darker user interface. The title text, however, refers to dark mode not in the sense of the color scheme but rather that receiving notifications bearing the bad news that you have been exposed to COVID-19 is "dark." Because nobody likes his current app, Randall decides to give in and create a dark mode, which would make his app much more desirable for users. <br />
<br />
Randall has published similar "useless useful apps" in [[937: TornadoGuard]] (a tornado-alert app that has lots of great features, except it doesn't actually alert the user about tornadoes) and [[2236|2236: Is it Christmas?]] (a web page that correctly identifies most days as "not Christmas", but then fails to identify Christmas Day as Christmas, for a >99% "accuracy").<br />
