Talk:958: Hotels

2018-11-19T16:31:42Z

162.158.134.190:

I hardly ever visit the same place twice, so I'd have to give hotels bad reviews ahead of time so that I get lower prices when I get there. Hell, why doesn't Black Hat do that? That way, he can avoid paying full price on his first visit to the hotel, which is what he wants, isn't it? The dishonesty of writing a bad review before he visits shouldn't be a deterrent to a person like him, so why not? '''[[User:Davidy22|{{Color|purple|David}}y²²]]'''[[User talk:Davidy22|<tt>[talk]</tt>]] 08:39, 9 March 2013 (UTC)

"Confirmed buyer" tags exist. Maybe Black Hat thinks that reviews without that tags wouldn't be convincing enough to be effective.

On the tragedy of You-are-a-dick: this is the real Tragedy of the Commons. Indeed quite different from Black Hat's tragedy of you-are-a-dick. My uni has a well-drawn version of this image on posters all over.

How did cue ball find out he liked it. Although it is only one person, knowing him directly gives him extra influence. I would say it is about the amount of influence of a review.--[[Special:Contributions/173.245.54.36|173.245.54.36]] 02:02, 15 February 2014 (UTC)
: Cueball seems to be friendly enough with Black Hat, so quite likely Black Hat simply mentioned that to Cueball before. [[User:Arifsaha|Arifsaha]] ([[User talk:Arifsaha|talk]]) 19:51, 21 November 2014 (UTC)
: While lying to Cueball about the quality of a hotel would reduce the overall demand, it is unlikely that both Black Hat and Cueball would both be travelling to the same city over the same date range, effectively meaning they are not competitors. Furthermore, if they were travelling together it is more likely that they would share a room, rental car or other resource, so having Cueball know his preferences benefits Black Hat.

Is the title text a reference to a scene in a horror movie? [[User:Arifsaha|Arifsaha]] ([[User talk:Arifsaha|talk]]) 19:51, 21 November 2014 (UTC)

:Highly unlikely, unless you can actually find a horror movie that incorporates those elements (I really hope you can't) -Pennpenn [[Special:Contributions/108.162.250.162|108.162.250.162]] 02:59, 4 March 2016 (UTC)

==Explanation==
{{incomplete|All features need an explanation, the version number war and title text as well. Do NOT delete this tag too soon.}}

This is the sixth entry in the ongoing [[:Category:xkcd Phones|xkcd Phone series]], released the day after Apple announced their new {{w|iPhone 8}} and the higher-end {{w|iPhone X}} (pronounced iPhone 10) with facial recognition features.

===List of features (clockwise from center/top)===

; Front camera (centered for eye contact during video chat)
: Front camera is a common feature of smartphones. The camera lens is located on the same side of the phone's case as the main screen and therefore it is possible to capture the image of the user's face looking at the screen and display the interlocutor's face on the screen simultaneously, enabling video chat. However, as the camera is usually located above the screen, a user looking at the displayed image of the other person directs his or her eyes at the center of the screen and not at the camera's lens. This is very visible on the other end of the chat as if the person talking was looking down and not in the interlocutor's face which is an uncomfortable situation for most people. For this reason, professionals involved in movie or TV-making, like actors or reporters, are trained to look straight into the camera's lens while talking, which creates impression of looking straight at the viewer's face. During a video chat, however, looking into the lens of an above-screen camera does not allow one to see the interlocutor's face clearly because it is then in the peripheral field of vision.

: To solve this conundrum, Randall proposes locating the camera lens right in the middle of the screen. Therefore the user looking at the screen to see the other person's face would be also looking at the lens, creating an impression of a straight look on the other end of the chat. This is absurd since the lens would then take place of some of the center pixels of the screen, not allowing the display the center part of the captured image of the other person's face (like eyes and/or lips) which is most important for nonverbal communication. Such location of the camera lens would also likely interfere with touch-screen function. It will make other applications on the phone difficult to use, since virtually no user interface is designed to accommodate for a blind spot in the center.

; Full-width rear camera
: Phone cameras tend to have lenses which are quite small and round or square -- same width as height. Full-width makes it sound like the camera lens is really wide, as in a long oval or rectangle shape. This generally would not accomplish anything worthwhile, unless it allowed you to take one-shot panorama photos.

; CDC partnership - phone automatically administers seasonal flu vaccine to cheek every year
: U.S. {{w|Centers for Disease Control and Prevention}} is a government agency tasked with addressing public health concerns such as infectious diseases, including seasonal flu. A common way of limiting spread of an infectious disease is {{w|Vaccine|vaccination}}, which most often involves administering a specially prepared medicine via an {{w|intramuscular injection}}. This features implies that the phone would automatically perform such an injection once a year, by shooting a needle out of a small aperture while the user is holding the phone to his or her cheek during a call.

; 12-function
: Most smartphones can be used for more than 12 different things. However, this may refer to the 12 basic functions of calculus (identity, squaring, cubing, square root, logarithm, exponential, reciprocal, sine, cosine, greatest integer, absolute value, and logistic), or the twelve function keys on a modern keyboard (more than the ten on the original IBM PC keyboard). Alternatively it may be a reference to calculators: basic models are sometimes referred to as four function calculators (addition, subtraction, multiplication and division), and complex scientific calculators may advertise 250 or more functions.

; Dishwasher safe
: Usually a feature of plastic containers or fancy dishes. Unlikely to appear on a smartphone, though potentially useful if you need to clean your screen.

; GPS transmitter
: Many smartphones have a receiver for the Global Positioning System, which allows a phone to compute its position based on signals from the constellation of GPS satellites. However, a device with a "GPS transmitter" would broadcast signals that would interfere with the GPS receivers of all devices nearby.

; 3-G acceleration
: Usually, a phone is 3g compatible if it uses a certain standard ("third generation") for data transmission. However, 3-G acceleration implies the phone can accelerate at a rate or 3 times the acceleration of gravity, or approximately 30 m/s².

; Portable, solar-heated
: Portability is pretty much the entire point of using a ''mobile'' phone, so advertising portability is rather pointless. Solar ''power'' charging could be a very useful feature on a phone, but solar ''heating'' usually applies to plumbing, where a water tank is heated by the sun and used to supply hot water to taps. Technically, as the sun heats up everything on Earth, the phone is in fact solar heated.

;Pore-cleaning strip
: Something sticky on that location would be very annoying for people trying to use their beards to make a call. See also [[777: Pore Strips]]

; Maximum strength
:Medicines are often sold a "Maximum strength", as in the highest dose allowed by law or allowed without a prescription. For phones, there are sometimes "hardened" or "ruggedized" versions which are designed to survive harsher environmental conditions such as surviving drops and collisions, excessive water and dust, etc. So Maximum strength could indicate a "ruggedized" phone, though a screen that extended past the edges would likely have the opposite effect.

; Never needs sharpening
: Phones do not need to be sharpened in the first place{{Citation needed}}. This is a feature more likely to be found in a knife advertisement (especially for a knife that cannot be sharpened, like a serrated or ceramic blade).

; Can survive up to 30 minutes out of water
: This is a play on the common IP-rating of water resistance, which is typically rated for submersion to a rated depth for 30 minutes. A phone which could only be used or carried for 30 minutes and then needed to be immersed in water would be rather inconvenient.

; Exclusive Audubon Society app identifies birds and lets you control their flight
: {{w|National Audubon Society}} is a non-profit organization dedicated to conservation of nature, mainly of birds, also organizing open {{w|birdwatching}} events. An app that identifies bird species, as for example from a photo of a bird made by the smartphone itself, would be cool. An app allowing you to control the bird's flight would be way cooler, but it is not possible at the current state of technology - and it would fly in the face of the Audubon Society core activity. This is a reference to {{w|Unmanned_aerial_vehicle|drones}} (artificial "birds") which are often controlled by a smartphone app. This may also be a reference to [[1425: Tasks]], in which an app that can recognize if a bird is on camera is proposed.

; Extra screen
:Because of the center camera, an additional section of screen was added. This is similar to the new iPhone, which also has a few extra pixels up there.

; Wireless charging port
:An oxymoron; because wireless charging has no wires, it needs no port.

; Safe for ages 6-8 months, 10 months, 18 months-3 years, and 12 years and older
:Usually an item is deemed safe for a particular age or older, or (in the case of toys) is recommended for a particular age range. This is unusual in that it's a hodge-podge of age ranges with no apparent reason why some ages are safe and others are not. It may be a parody of drug commercials that list several age ranges for which the drug had to be separately approved.

; Screen goes past the edge
:A parody of the trend of "edge to edge" displays in recent generations of smartphones

; High thread count CPU
:A CPU thread is a task the CPU performs. Several threads may share memory making them a process. Threads are meant to run in parallel and the operating system distributes the workload on the available hardware execution units. These execution units are sometimes called hardware threads, especially when there is more than one per core. For example, the Intel Core i7 7700 is considered a 4-core, 8-thread CPU. The vague "high thread count" statement could make sense in this context, however, it is most likely a joke about bedding, where it is an actual selling point.

; Shroud of Turin-style facial transfer unlock
:The {{w|Shroud of Turin}} is a {{w|Pareidolia}} facial image of the face of {{w|Jesus Christ}}. Presumably, to unlock this phone, the user would have to physically press their face against the phone, the way Jesus Christ's allegedly transferred to the shroud. This is likely a reference to the iPhone X's FaceID unlock, which uses a ''photograph'' of your face to unlock it and which had attracted [https://www.wired.com/story/iphone-x-faceid-security/ significant criticism] immediately before this comic came out.

; Fonts developed by NASA
: Between 1975 and 1992 NASA used the {{w|NASA insignia|"worm" logotype}} in its insignia. It was a special font omitting the horizontal bar in the capitalized letter A. May be a reference to many advertisements that claim their product uses technology developed by NASA. This seems impressive, as NASA technology does tend to be quite strong and advanced, as they claim at their [https://spinoff.nasa.gov/ spin off] website. However, it would not be as impressive due to fonts having very little to do with NASA's core operations.

; Includes applicator
: What tampon packages, cosmetics, paints, and other products often say. An applicator for a phone would be absurd since the phone cannot be applied, spread, inserted, or attached to something else.

; Burns clean coal
: There is a push for clean energy production due to pollution concerns.  Using heat to generate operating electricity for a mobile phone is absurd, as the apparatus to burn any fuel and then extract electricity from that heat would be very large compared to the phone itself, and thus be impractical for a mobile.

; Pre-seasoned
:Pre-seasoned typically refers to cast iron cookware which is ready to use out of the box, as opposed to needing to season it with oil and heat. It can also refer to packaged meats which are ready to cook without needing to be seasoned with herbs and spices, or timber that has been dried and is ready for use.

; Broad-spectrum SPF 30
:The xkcd phone somehow gives an SPF 30 level of skin protection from the sun.

; College-ruled
:College-ruled is a style of notebook paper having narrower lines in order to fit more text per page.

; Sterile packaging
:Useful for medical supplies, less so in a phone.

; Radium backlight
:The discovery of the radioactive element radium sparked a brief fad in which some watch makers painted watch faces or hands with a paint containing radium and a radioluminescent substance such as zinc sulfide which converted the radiation from the radium into visible light. This allowed the time to be read at night without needing an external power source for the light. However, it was eventually realized that regular exposure to radium could result in radiation poisoning, particularly for the workers assembling and painting the watches. A radium-based backlight would therefore be both potentially dangerous (especially for an object carried on one's person much of the time) but also largely useless, as the radioluminescent light is rather dim compared to conventional phone back lights.

; 4K pixels (50×80)
:This refers to having 4,000 pixels in the screen in total, rather than a screen width of ~4000 pixels. TV's advertised as "4K" are typically up to 4096 × 2160 pixels, or 8.8 million pixels. That would be outstanding for a cell phone whereas 4,000 pixels total would be horrendous. As a comparison, the old Commodore VIC-20 with a resolution of 176 × 184 would have over 8 times the pixels of this phone. It is however quite close to the screen resolution of the sturdy Nokia 3310, boasting a total of 4032 pixels positioned 84 × 48.

In the caption below the phone [[Randall]] presents many different version numbers:
*The number 6 is in correct order of all the xkcd phones
*The {{w|Roman numerals|roman number}} VIII refers to the newly announced {{w|iPhone 8}} and jokes about the roman number X below
*Version number 10 is the current version of Microsoft Windows after omitting the number 9
*The {{w|iPhone X}} was announced together with the iPhone 8 by Apple on September 12, 2017, a day before this comic was released. Apple clarified X must be read as the roman number 10, so for additional absurdity two xkcd phones share the same number, using different numeral
*The number 26 refers to...
*In the year 1876 {{w|Alexander Graham Bell}} received the U.S. Patent No. 174465 for the {{w|invention of the telephone}}, but there is still a {{w|Elisha Gray and Alexander Bell telephone controversy|controversy}} whether {{w|Elisha Gray}} was the first who presented a working telephone.
Below of this numbers Randall states that xkcd isn't responsible for this ''nonconsecutive version number war'', but, as it can be seen here above, he attempts to win. And by counting parallel version numbers xkcd defeated Apple 6:2. The symbols at the end are ™ for trademark, ® for registered trademark, and © for a copyright protection. The degree symbol ° after the letter C could be a play with degree Celsius.

In the title text Randall attributes privacy concerns about the facial recognition feature. A picture of a face will only be used for this new feature but never stored on the device nor transmitted to internet. A ''small'' side effect may be that the famous selfie pictures aren't possible anymore, as well as video calls.

Talk:1871: Bun Alert

This is basically the title text from 1682. Is it just me, or has Randall been running out of ideas lately? [[User:Jaalenja|Jaalenja]] ([[User talk:Jaalenja|talk]]) 13:31, 2 August 2017 (UTC)
:In all fairness, Randall has been known to play the long game. There might be a thread to pull here. {{unsigned ip|172.68.143.186|13:44, 2 August 2017‎ (UTC)}}
::Yea, Randall has built on earlier ideas before. E.g. 1818 being built on an idea from What-If 141. It's non-indicative of a lack of ideas. But the notion that ideas are a finite resource is silly anyways. Watch the talk he gave at Google in 2007, it's on YouTube, and there's a bit in there where he talks about how he comes up with his comics.

No idea why he's picked bunnies specifically, maybe that will become apparent in a future strip. Considering just this standalone comic, it seems to be a parody of apps that increasingly swamp the user with notifications about pointless things that one might imagine nobody would ever care about. In this instance, it might be imagined that few people would care about notifications for bunny sightings, but in the last pane it appears that someone truly does. This might compare with notifications for rare pokemon sightings in Pokémon Go (not provided in-app but there are groups on facebook etc. that alert users to rare pokemon / legendary raids) - with the difference that bunnies are extremely common. Also, is it significant that he specifically uses the word "buns" instead of "bunnies"? There may be a connection with the observation that they are just like little hopping loaves of bread.[[Special:Contributions/141.101.98.208|141.101.98.208]] 14:45, 2 August 2017 (UTC)

1839: Doctor Visit

2017-05-19T12:18:24Z

162.158.134.190: /* Explanation */

{{comic
| number = 1839
| date = May 19, 2017
| title = Doctor Visit
| image = doctor_visit.png
| titletext = According to these blood tests, you're like 30% cereal.
}}

==Explanation==
{{incomplete|Created by a BOT - Edited by a human. Needs more humans.}}
[[Cueball]] is visiting his doctor [[Ponytail]], apparently for a general medical checkup.

While there is nothing wrong with him medically, the doctor wonders why he continues to work for many years in spite that all his body parts are individually fragile. Compared to man-made structures, like the USB cables mentioned by Ponytail which quickly begins to fray, it's surprising the body can survive for so long and sustaining so much wear and tear,. Actually the body gets stronger and fitter the more it is used, as opposed to USB cables.

Ponytail specifically mentions his eyes which are so fragile and exposed. Yet most people go through a whole life with both eyes intact, although the vision it self may be impaired. The human reflexes and the shape of the skull around the eyes has a lot to do with the fact that it is possible to protect such fragile structures for a lifetime.

It should be noted that the human body is constantly replacing dead/injured cells and needs a constant supply of energy and nutrients to keep this process going on. USB cables, while apparently tougher than blood vessels on first inspection, have no such repair mechanism.

The doctors final remark is that Cueball is mainly made from dissolved bread, which is true "from a certain point of view." And this is taken further in the title text, where she states that the blood tests reveal he is 30% {{w|cereal}}.

Cueball has gone to Ponytail for a health checkup.

Cueball: Everything look good?
Ponytail: I don't get how your body has been moving around for years and still works a all. My USB cables fray after like a month.

Ponytail: Your heart has been pumping for decades without pausing for even a few minutes. And your EYES! They're so fragile and exposed!

Ponytail: You're full of all these high-pressure fluids and intricate parts that could kill you in seconds if they stopped working!

Cueball: .. Can you just tell whether I'm healthy?
Ponytail: Yeah, you're fine. Which is weird, given that your body is basically made from dissolved bread
