813: One-Liners

2024-06-08T08:56:29Z

172.70.251.121: Added the title text one liner in the same style as the other ones to see it directly and not have to scroll up during reading (make it homogeneous).

==Explanation==
In this comic, Randall presents a series of phrases, ordered by how likely they are to be used as a {{w|One-line joke|one-liner}} by a character in an {{w|action movie}}. One-liners are short, punchy phrases, typically witty or funny, and are routinely used in films by the antagonist to taunt the protagonist (or vice versa). The perfect one-liner leaves the recipient at a loss for a comeback, and should make sense immediately. If the phrase doesn't make sense or has to be explained, the effect is lost.

The phrases shown adhere to the witty and punchy stereotype of a classical one-liner, but quickly become more niche and only understandable for an informed subgroup.

;You're going down the memory hole now, asshole.
:The {{w|Memory hole}} is a mechanism for redacting documents, photographs, etc., and a reference to {{w|George Orwell}}'s novel ''{{w|Nineteen Eighty-Four}}''. In this instance it implies that the character on the floor is about to be 'erased' from existence.

;Hey! You forgot to carry the two.
:[[Cueball]], lying on the ground in a fight, while his opponent has the high ground, still appears to be at an advantage since he has a gun and his opponent only has a knife, is pointing out an arithmetic error in his opponent's calculations. This may simply be Cueball adding insult to injury "I'm about to shoot you, but first I'm going to point out that you suck at math". Alternatively, it could be a ruse to distract the knife wielding opponent, or a case of well-timed [[356|nerd-sniping]]. It could also be that Cueball is buying time to cock or reload his gun. Alternatively Cueball is implying the missing carry caused the shown situation, and Cueball is monologuing (albeit a very short monologue), which may also serve to explain to the audience how his victory was achieved. Such an explanation would likely be necessary, as it is difficult to imagine any situation where this would be the case. A fourth way to explain the situation is that Cueball is stating with this phrase, that his opponent overlooked something small but critical, leading to a non anticipated (wrong) outcome. In this case his opponent would have overlooked that Cueball is carrying a gun, yielding to an unexpected and unfortunate outcome of his knife attack.

;Looks like the Fed just lowered the interest rate.
:[[Ponytail]] is standing on a desk with documents on it, probably in a banking or business related environment, dominating [[Cueball]] in a sword fight. The {{w|Federal Reserve System}}, usually referred to as The Fed, is the central banking system in the United States. The interest rates are usually lowered during a recession or a crisis, to revive the economy by providing businesses with cheap money. The dropped rates correlate with his chances to win and reflect his troubled situation.

;Guess you should've scrolled ''all'' the way to the bottom before clicking "Agree."
:A common feature encountered when registering for user accounts or installing software is a very lengthy {{w|Terms of service}} document, describing the things you agree to abide by. The vast majority of people simply click Agree without reading the document, essentially agreeing to anything and everything that the author decided to include, which sometimes leads to things like [http://www.huffingtonpost.com/2010/04/17/gamestation-grabs-souls-o_n_541549.html giving your immortal soul to a company]. In the context of this panel, perhaps the user agreed to be executed at random.

;Bangarang, motherfucker.
:This phrase is very similar to the line "Yippee-Ki-Yay motherfucker" used by {{w|John McClane}} in the ''{{w|Die Hard (film series)|Die Hard}}'' series. {{w|Bangarang}} is, among other things, the Jamaican word for "uproar." It was popularized (without the addition of 'motherfucker') as the cheer of the {{w|Lost Boys (Peter Pan)|lost boys}} in the film ''{{w|Hook (film)|Hook}}'', via the popular dubstep Skrillex song {{w|Bangarang|”Bangarang”}}.

;Upgrade to the latest version of Adobe Flash player to view THIS content, bitch.
:This title text is another suggested one-liner phrase, referring to an update reminder that would frequently pop up when one attempted to view visual media content on a webpage. After delivering the line, the character triggers a detonator (Double colons are sometimes used in text to denote an action), presumably setting off an explosive of some kind.
:The phrase states that you need the latest {{w|Adobe Flash}} player to view this (presumably for older flash players too spectacular) explosion.
:Also wordplay is involved since a "flash" is one visual representation of a explosion.
:Of course, in real life, one doesn't need a "flash player" to view an explosion,{{Citation needed}} especially due to its [https://www.adobe.com/products/flashplayer/end-of-life.html official end-of-life] at the end of 2020 rendering the software completely defunct.

==Transcript==
:Probability of phrases becoming action movie one liners:
:[Panels are arranged from More Likely on the left to Less likely on the right.]

:[A woman points a gun down at Cueball who is on the floor, his gun just out of reach.]
:Woman: ''You're'' going down the memory hole now, asshole.

:[Man on ground points gun up at blade-armed man standing next to a board with science on it.]
:Man with gun: ''Hey!'' You forgot to carry the two.

:[Ponytail on desk points sword at man standing on floor.]
:Ponytail: Looks like the Fed just lowered the interest rate.

:[Cueball with gun looks down at Megan slumped on floor.]
:Cueball: Guess you should've scrolled ''all'' the way to the bottom before clicking "Agree."

:[Megan holds pistol to the back of the head of Ponytail holding a rifle.]
:Megan with pistol: Bangarang, motherfucker.

2712: Gravity

==Explanation==
{{incomplete|Created by THE UNIVERSE FROM A PIECE OF FAIRY CAKE- Please change this comment when editing this page. Do NOT delete this tag too soon.}}
In this interactive comic, the viewer pilots a small spaceship throughout a vast area in space. The viewer is capable of exploring various bodies and planets within the play area, many containing easter eggs alluding to the book What If? 2 and previous xkcd comics. The flight mechanics are largely, if not entirely, Newtonian, so the vessel is capable of using the gravity of planets to alter its trajectory or even enter orbit. The spaceship has several indicator circles around it which appear when a gravitational body comes into range, showing the direction towards their center of gravity and the size of the body.

The arrow keys rotate the spaceship and accelerate it forward and backward. On mobile the comic will full screen, pressing either side of the center rotates the spaceship, and pressing in the center accelerates it forward. There is no way to accelerate backward on mobile.

It is fairly easy to fly between planets as long as you pay attention to orbital mechanics don't just floor the accelerator. The background stars show your velocity and orientation relative to the nearest gravity well. If you are having difficulties navigating space, point towards a gravity orb and accelerate for only a few seconds. Wait until the background stars spin wildly, and then reduce your velocity to 0 before gently accelerating towards to object.

There is no "universal" point of view — the bottom of the window, "down", is oriented towards the object exerting the most gravity upon the player. Multiple things found in this comic draw attention to this, such as how on Earth Ponytail says to White Hat, "I checked downforeveryoneorjustme.com and it says just me", and he replies "Yeah, I guess down isn't down for everyone."

Throughout the play area are coins that change the spaceship into different rockets and non-space based vehicles, including humans.

The comic promotes Randall's new book [https://xkcd.com/what-if-2/ What If? 2], which was released in September and is available for purchase. Many of the planets contain references to various What If? articles.

The comic is similar to [[1608: Hoverboard]], which celebrated Thing Explainer instead.

"Is it an angry bobcat?"

"It might not be."
|in code: <code>[22820,-18920]</code><br>in game: <code>[45640,37840]</code>
|
|Y
|
|
|The XKCD cast react to giving each other What if 2? as a present. Gravity at the bottom of the missing quarter of the planet is inescapable. Black Hat gives Cueball a "gift" which he claims "might not be a bobcat", a reference to [[A-Minus-Minus]]
|-
|<code>maw1</code>, <code>maw2</code>, ... <code>maw14</code>
|'''Black hole cluster'''
|
|
|
|
|
|
|A cluster of black holes with extremely high gravitational strength, set to the maximum of 2048. Not particularly easy to land on with multiple conflicting gravitational fields, but once landed on, rather difficult to escape.

"What's one question that you would be unwilling to answer?"
"Oh no."

"Handle this artifact with great care. It contains a magical wizard's potion which the ancients called 'trinitrotoluene'"
|(-35070,-2500)
|
|
|
|
|A reference to the Steerswoman series of books by Rosemary Kirstein. Includes a number of references to the series, including a group of people observing a small object orbiting the planet.

Trinitrotoluene is better known as {{w|TNT}}, a powerful explosive.

|'''Peeler'''
|
|(-9270, 620)
|
|

221: Random Number

2022-12-07T12:08:54Z

172.70.251.121: /* Trivia */

{{comic
| number = 221
| date = February 9, 2007
| title = Random Number
| image = random_number.png
| titletext = <nowiki>RFC 1149.5</nowiki> specifies 4 as the standard IEEE-vetted random number.
}}
==Explanation==
The comic specifies a function (in a {{w|C (programming language)|C}} similar syntax), which judging by its name should be designed to return a random number. Most functions of this form are random number ''generators'', meaning that on subsequent calls they return ''different'' random numbers. But the programmer has instead implemented a function that just returns the ''same'' random number each time, which, while it could indeed have been truly randomly chosen by rolling a die as the [[156: Commented|comment]] documented, is essentially worthless were it ever to be called more than once (with the expectation of different, i.e., random, results). In other words, the results over time would not be random at all, but completely predictable and deterministic.

The {{w|IEEE}} is the organization responsible for maintaining a number of computer standards. An RFC, or {{w|Request for Comments}}, is a formal document put out to computing experts by {{w|IETF}} in the hopes of becoming a future standard. However, RFC 1149 was an {{w|April Fools' Day Request for Comments|April Fools' joke}}, defining how carrier pigeons can be used to transmit Internet packets. "<nowiki>RFC 1149.5</nowiki>," meanwhile, simply does not exist.

==Trivia==

* The well-known "helper website" ([http://gChq.github.io/CyberChef/#recipe=XKCD_Random_Number() CyberChef]) has a function that simulates XKCD's program.
* Esolangs.org features a [http://esolangs.org/wiki/user:XKCD_Random_Number challenge] that requires you to rewrite the program in XKCD's comic in another programming language, as either a function or a full program that prints the "4".
* The most commonly used Java ORM framework for SQL databases is '''Hibernate'''. It uses the xkcd method to generate a random UUID generation strategy. Like, seriously.
From the hibernate-core-5.6.7.Final.jar:

<nowiki> public class StandardRandomStrategy implements UUIDGenerationStrategy {
/**
* A variant 4 (random) strategy
*/
@Override
public int getGeneratedVersion() {
// a "random" strategy
return 4;
}
}
</nowiki>

==Transcript==
[A computer program.]
int getRandomNumber()
{
return 4; // chosen by fair dice roll.
// guaranteed to be random.

Talk:2704: Faucet

2022-11-29T21:02:19Z

172.70.251.121:

Are faucet designs considered to be confusing? I'm never confused by normal ones like [https://www.ikea.com/us/en/images/products/sundsvik-kitchen-faucet-chrome-plated__0756711_pe749051_s5.jpg?f=s these] {{unsigned|Flekkie|02:12, 29 November 2022}}

:Yeah I came here wondering the same thing. Is the joke perhaps not so much that the controls are confusing in terms of intent, but just in terms of determining the bounds? Eg, with two identical faucet controls and identical water pressures, "full blast hot" still translates to something radically different, if one building has a water heater set to 120F and the other building has a water heater set to 160F.{{unsigned ip|172.69.170.189|02:46, 29 November 2022}}

:(I find °F confusing, personally, but...) ...the easiest thing is to have two taps, one hot and one cold. Yes, they can combine into a single spout, but there are various conflicting plusses and minuses of that over having the two independent ones per outlet. Speaking (as I'm sure mixer-tap afficionados worldwide will appreciate) as a Brit. [[Special:Contributions/172.70.85.24|172.70.85.24]] 03:03, 29 November 2022 (UTC)

::Relevant Tom Scott video: [https://www.youtube.com/watch?v=HfHgUu_8KgA Why Britain Uses Separate Hot and Cold Taps]. TL;DR: British houses used to get their hot water from rat-filled cisterns so they wanted to keep the hot water separate from the cold water, and old habits die hard. [[Special:Contributions/162.158.63.152|162.158.63.152]] 03:34, 29 November 2022 (UTC)

:::Silliness of dual-taps aside, that doesn't solve the issue of identical tap hardware yielding radically different results depending on what the hot water thermostat is set to. Maybe that's not the original joke (I'm still not sure what it was) but it's worth mentioning at least. [[Special:Contributions/172.69.170.146|172.69.170.146]] 03:39, 29 November 2022 (UTC)

: I don't think those are confusing, but in many cases the feedback is too slow (e.g. due to the water in the pipes coming from the hot water source having cooled since the tap was last used), or inconvenient (e.g. the pressure of the hot water not being enough to trigger on-demand gas heaters). While theoretically that design allows exploring the whole temperature/pressure space, in practice one needs some trial-and-error and delay to find the correct setting (as Randall points out in the title text) to make it work. --[[User:Waldir|Waldir]] ([[User talk:Waldir|talk]]) 10:54, 29 November 2022 (UTC)

:It's really a joke we are too European to understand. Visit the US to see faucet control disasters in all their glory. [[Special:Contributions/172.68.51.203|172.68.51.203]] 10:56, 29 November 2022 (UTC)

:: Yeah, here in Europe I've seen faucets with mechanical thermostats to regulate the temperature and therefore two dials for either flow or temperature. This was more than 20 years ago. --[[User:Sarsey|Sarsey]] ([[User talk:Sarsey|talk]]) 12:01, 29 November 2022 (UTC)

:: Funny, the absolute worst faucet I experienced was in this fall in England (which is part of Europe for some definitions but not others). The temperature selection knob had 180° ambiguity---especially for my poor vision when uncorrected---and no barrier between maximum hot and maximum cold. So, I spent a shower thinking I was operating at mid-range and wondering why there seemed to be no middle ground between freezing cold and scalding hot. Fortunately had an epiphany while exploring the town. [[User:Philhower|Philhower]] ([[User talk:Philhower|talk]]) 14:13, 29 November 2022 (UTC)

I sympathize with Randall here; even controls designed to independently control temperature and flow rarely meet both the "intuitive to use at a glance" and "function as described" requirements to make them non-confusing. [[User:Dextrous Fred|Dextrous Fred]] ([[User talk:Dextrous Fred|talk]]) 03:44, 29 November 2022 (UTC)

Wouldn't it be super simple to just have a slider that goes from hot to cold, and a second one that goes from slow to fast flow? Or one for hot, one for cold, with the higher the slider goes, the more the flow is increased? I don't see how much simpler you can get it. Hell, you could even use a dial for temperature (all dials turn clockwise to increase) with a digital readout. [[Special:Contributions/172.70.131.44|172.70.131.44]] 05:25, 29 November 2022 (UTC)

: I suppose the issue with that is that, unlike simple mixer taps that control the flow of hot and cold water independently, relying on the human to find the right mixture that creates the desired flow and temperature, what you're describing requires a more complex system that is able to do that process automatically, so it can't be a simple mechanical valve. It would require temperature and pressure sensors for both the hot and cold water streams, and it would have to dynamically adjust the physical valve settings depending on all six parameters (position of the flow handle/slider/knob, position of the temperature handle/slider/knob, temperature of the hot water, temperature of the cold water, pressure of the hot water, pressure of the cold water). I'm not even sure this is possible with a fully mechanical system — likely some electronics would need to be involved, which might complicate things. --[[User:Waldir|Waldir]] ([[User talk:Waldir|talk]]) 10:50, 29 November 2022 (UTC)

This is probably the very first xkcd comic where I have absolutely no idea where Randal is coming from. While different people have different preferences for different designs, I've never heard of anyone being confused by any faucet design.
Maybe he's trolling us, by trying to get a rise out of people wondering what the hell he's talking about? [[User:Bischoff|Bischoff]] ([[User talk:Bischoff|talk]]) 08:20, 29 November 2022 (UTC)

This may be a reference to "Design of Everyday Things - Dan Norman" or books in that direction. Although he talked a lot more about creating doors wrong he also mentioned faucet designs as terrible. [[Special:Contributions/198.41.242.29|198.41.242.29]] 09:17, 29 November 2022 (UTC)
::  I was initially drawn to the parallel/derivation from the "{{w|Build a better mousetrap, and the world will beat a path to your door|Build a better mousetrap...}}" concept, which vastly predates {{w|Don Norman|''Don''}} Norman. But it's such a widespread trope that I can't be sure it should be mentioned 'officially'. [[Special:Contributions/172.70.86.61|172.70.86.61]] 11:13, 29 November 2022 (UTC)

: I am actually puzzled by how many people ''don't'' relate to this, judging by the comments here. I guess I've been unlucky with the faucets I've encountered so far? Over the years I've had spontaneous conversations with multiple people abut how tap designs are either inconvenient (i.e. hard to find the right handle positions to produce the desired temperature and flow), or confusing to use, especially for hotel showers. In fact I'm adding this comment mostly so other people who share the same perception don't feel gaslighted or otherwise confused by so many people not recognizing this issue. --[[User:Waldir|Waldir]] ([[User talk:Waldir|talk]]) 10:50, 29 November 2022 (UTC)

Is that hairy? looks like him? [[User:Mushrooms|Mushrooms]] ([[User talk:Mushrooms|talk]]) 10:07, 29 November 2022 (UTC)
:I think it could be, but he is looking different with the hair and because of the scruffy looks his hair standing up could be because he has torn in it. I think it is better not to include it as a Hairy comic. --[[User:Kynde|Kynde]] ([[User talk:Kynde|talk]]) 13:34, 29 November 2022 (UTC)

Is it too pedantic to point out the distinction between a helix (the shape of the control) and a spiral (mentioned by the character)? {{unsigned ip|172.70.162.135|10:28, 29 November 2022}}
:Not really, but it could be a very shallow (by radial increase/decrease per turn) 3D spiral, I'm more concerned by the "tightening", wondering if it's a flexible spiral/helix that is manipulated dynamically, rather than merely a tap* with a funny-shaped handle/head to rotate through into the backplate.
::<nowiki>*</nowiki> - 'faucet' just makes me wait for a "force it" pun. It's a very American word that I'm not personally aware of being used throught the rest of the anglosphere. Maybe Canada, but probably not Aus/NZ/etc if my uptake of their TV/film exports is correctly remembered... Somebody may want to correct me on this issue, or add English As A Second Language metrics to this.
:What is also interesting is that the 3D-perspective drawing by our in-frame inventor, upon the perspectivised drawing surface as depicted by Randall, makes it look like very much like an actual sticky-outy object within the drawn world. Like it's actually a moulded/similar relief model/mockup, surrounded by the more standard 'wall notes' used to suggest on-the-go calculations/annotations. An interesting artistic choice (or possibly an unintentional consequence) by Randall. [[Special:Contributions/172.70.86.61|172.70.86.61]] 11:13, 29 November 2022 (UTC)

I think it should be added that the issue is mainly for the US. In Europe, and in the other of the rest of the world - except US - the thermostatic head has replaced most other faucet in shower, and the hand washing is not so much of an issue. My shower in some US hotels were a nightmare, where I remember taking multiple minute to understand how it might work. {{unsigned ip|172.71.130.80|11:03, 29 November 2022}}

I think it should be added that the issue is mainly for Europe, especially Americans traveling in Europe. In the USA, where proportioning valves are common and anti-scald protection is mandated by code, controls are both intuitive and safe. {{unsigned ip|172.70.210.49|13:11, 29 November 2022}}
:So funny that these two comments in a row says the opposite. I'm from Denmark and where I sometimes dislike the designs of a faucet I have almost never found one for a tap that was a problem to understand. Sure for a shower there can be some issues, mainly because it can be too hot and problematic to stand under them when turning them on the first time. But it seems to me that this is not a serious problem in Europe. And from reading above it seems like this is in fact a US problem only. But the last comment says the opposite. by the way both sigantures unsigned, so did a check and found they where from two different IP and with time between. Was wondering if someone was trolling by writing the same comment twice with reversed meaning. But seems to not be the case. Have added signatures now. --[[User:Kynde|Kynde]] ([[User talk:Kynde|talk]]) 13:34, 29 November 2022 (UTC)

::I vote that "confusing faucets" is an American problem. In some places it was hard to set the faucet exactly right (either because of faucet lag, which is the fault of the water lines and not the faucet anyway, or because the controls were highly non-linear around the target I wanted), but the direction in which the controls moved was always fairly clear.
::I have been living in France most of my life, including visits to really old homes. I only ever met faucets of three kinds. In all of them water comes from a single outlet. Type 1 has two flow control knobs (one hot, one cold); type 2 has a single handle that can move in two angular directions (one for temperature, one for flow); type 3 [https://en.wikipedia.org/wiki/Thermostatic_mixing_valve (thermostatic valve)] has one knob for temperature and one knob for flow. Faucets use types 1 and 2, showers can use type 1, 2 or 3. Only type 3 ever confused me the first time, and that was when I was a young child (I would guess age 8 or so?). I suppose the under-the-hood engineering gives rise to all sort of interesting tradeoffs between those three types, but from a user’s perspective they are all reasonable.
::I have traveled to the UK multiple times and lived there for some time. It was mostly the same, though I have seen some dual-taps (essentially type 1 but with one tap per knob). It may be a bad user experience, but it is not confusing.
::I have been to multiple other countries on short trips and do not remember any confusing faucets... except for one US hotel. That devilish shower had a single-knob control; the temperature increased over the whole range, and the flow was maximum at mid-range. I did not mind much that it does not explore the whole shower-space (the trajectory in the flow-temperature diagram was probably a super-optimized curve rather than a straight inverted V); but I did mind that it took a few minutes of exploration to understand what happened. [[Special:Contributions/172.71.126.15|172.71.126.15]] 16:07, 29 November 2022 (UTC)

My interpretation is that, for normal people, designing an intuitive faucet is easy: just one knob for temperature and another for flow. But designers seem to get overly creative for faucets and add all sorts of odd handles and gizmos. Figuring out a faucet at a hotel is often a task. Hence, in the comic, the designer is adding some sort of bizarre spiral handle when a regular one would be much easier. It's not that its hard to design a good faucet, but designers seem to have an odd blind spot for them. [[Special:Contributions/172.70.110.230|172.70.110.230]] 13:48, 29 November 2022 (UTC)

Why aren't there digital faucets? And if this is such a bold idea It's mine [[Special:Contributions/172.70.131.43|172.70.131.43]] 14:45, 29 November 2022 (UTC) paradoxical

::I find analogue faucets to typically be really difficult to control. Turn knobs are fine, but lifting or turning a single handle like many faucets nowadays have just don't give me enough precision. Now, my hand-eye coordination and fine motor control are bad, but not ''entirely'' terrible. So I think for some people, even turn knobs are going to be annoying to use. So digital inputs would probably make it a lot easier if you have a motor disability. [[Special:Contributions/172.68.51.108|172.68.51.108]] 20:55, 29 November 2022 (UTC)

Damn, you mean people don't just switch on the tap and cope with cold showers? Damn, major L.[[Special:Contributions/172.70.219.42|172.70.219.42]] 16:29, 29 November 2022 (UTC)

Just this morning, I was in the shower which has a single lever to control the mix of hot and cold water. I always turn it all the way up to get the hot water flowing and then move it down by small degrees until it is just right. With the lag in response for each successive change it takes a seemingly unnecessary amount of time to get it "just right". I would say that it is not so much "confusing" as it is "annoying". In this faucet there is no separate way to control the flow. The flow is maximized when there is an equal amount of hot and cold water, which of course is not necessarily the optimum temperature, because it takes a very small amount of cold water mixed with the hot to make it comfortable. [[User:Rtanenbaum|Rtanenbaum]] ([[User talk:Rtanenbaum|talk]]) 17:23, 29 November 2022 (UTC)

Regarding the transcript, which says "Below it is a box shape that dispenses water through a circle". What the ???. Can this be changed to, "Below it is a drawing of a spout"? [[User:Rtanenbaum|Rtanenbaum]] ([[User talk:Rtanenbaum|talk]]) 17:23, 29 November 2022 (UTC)
:Well, its not really a box shape since its a 2D drawing and boxes are 3D... so it should say "Below are 3 parallelograms that form a two-dimensional projection of a rectangular prism..." Or maybe, for brevity we can just say "Below it is a drawing of a spout." [[Special:Contributions/162.158.63.109|162.158.63.109]] 19:50, 29 November 2022 (UTC)

For hotel shower controls, even (especially?) if cleaned regularly, I find that they tend to lose the handy inlaid red and blue textures or overprinting to distiguish the relative functions of chrome or plastic dials and levers. But, even with them visible and discernable, they can be ambiguous. If a dial/rotary component has hot/cold (or flow-control) markings on the fitting it is sat upon then it tends to show which direction to twist it for which change. But if it's marked ''on the dial'' then there's two opposing conventions used for a fairly standard "arrow with increasing line-width towards the head" marker:
:1) Twist the dial in the direction of the more blue bit (incidentally showing more of the opposing red arrow) when you want the cooler temperature, this being a 'turn this way for more "blue water"' sort of thing,
:2) The thicker bit of blue is supposed to be read as aligned to something subtle, like a notch/ridge mark, upon the static backplate, meaning that you should twist the dial in the ''opposite'' direction to bring the "more blue" into play.
...though some (like central-heating radiator controls) do disambuguate this by having the red/blue meshed long thin triangles (and maybe digits/tick-lines to easily establish a position and any small change) hidden within a shroud with just a small window upon the 'meaningful' uppermost/foremost bit of the twisting pattern. Of course, the chances that any one hotel's chosen fitting is easily recognisable as the same as the last one you used in a different hotel (or the last visit to this one!) are not great. I'm sure there's going to be someone who collects "hotel plumbing" photos, or similar, to catalogue their sheer variety. Certainly it's something I might have wished to have started to do, but seems a bit late to begin now. [[Special:Contributions/172.70.91.53|172.70.91.53]] 19:37, 29 November 2022 (UTC)
:Here's an idea: put a little plastic window on the faucet and have the colour behind it turn red or blue. So depending on how it's made, the blue/red thing turns behind the plastic window, or the window shifts over the blue/red thing. Either way, if you can only see red, it's hot; and if you can only see blue, it's cold. And the colours won't get worn away since they are behind a little window.
