The choice of characters in this comic is...interesting. I never got the impression that White Hat was gullible. [[User:GreatWyrmGold|GreatWyrmGold]] ([[User talk:GreatWyrmGold|talk]]) 21:27, 7 December 2018 (UTC)

I can convince people that all of Randal's maps are real? [[User:Linker|Linker]] ([[User talk:Linker|talk]]) 00:53, 8 December 2018 (UTC)

But wait, how does driving north reach Alaska? I thought it was an island near Hawaii to the southwest. More seriously, should we mention that the Mercator does have useful properties such as preserving angles or is that too much for explaining the comic?

People putting a joke in the incomplete tag but completely ignoring the “Please mention here why this explanation isn't complete.” part is really annoying [[User:DrMeepster|DrMeepster]] ([[User talk:DrMeepster|talk]]) 07:38, 8 December 2018 (UTC)
:Good Dr. It is an autobot that fills in the first page of the explanation, and here it is always clearly incomplete. Others may later delete that it is a bot that has made the explanation, but not knowing if it is complete, but also now knowing if it is not. And then there is the large text stating do not delete too soon. So I agree that reasons should be given for old comics that are suddenly listed as incomplete, but that the newest comic is listed as incomplete is just basic info ;-) --[[User:Kynde|Kynde]] ([[User talk:Kynde|talk]]) 18:29, 9 December 2018 (UTC)
::Why doesn’t the autobot explicitly say that it is incomplete by virtue of being a new comic? [[User:Saklad5|Saklad5]] ([[User talk:Saklad5|talk]]) 19:54, 9 December 2018 (UTC)

Perhaps it should elaborate on "ridiculous" i.e. Cueball claims that the Mercator projection changes the topology of land and water masses, not just their relative size and (oh it's a long time since I did maths, so I'll call it) squishiness. [[User:ColinHogben|ColinHogben]] ([[User talk:ColinHogben|talk]]) 10:19, 8 December 2018 (UTC)

Mercator map projection has the advantage that shortest line between two points on Earth (on globe) is straight line in this projection. --[[User:JakubNarebski|JakubNarebski]] ([[User talk:JakubNarebski|talk]]) 11:17, 8 December 2018 (UTC)

The largest islands in Lake Ontario are either the western parts of the Thousand Islands or the southern-most part of the City of Toronto. Neither would be considered "in the middle" of the lake. While Lake Erie has some islands in the middle, like Middle Island, Lake Ontario does not have similar navigation targets/hazards. [[User:Nutster|Nutster]] ([[User talk:Nutster|talk]]) 17:11, 8 December 2018 (UTC)

Both the XKCD comic (in its caption) and the explanation (in its current form) misuse the word "fact." The point that Randall is trying to make is that you can convince people of '''lies''' or anyway '''mistaken ideas''' by referring to the Mercator projection. '''Facts''' are by definition correct. [[Special:Contributions/162.158.63.166|162.158.63.166]] 13:53, 9 December 2018 (UTC)
::Facts can also be anything ''presented'' as objectively real. Under that definition, this is proper usage. [[User:Saklad5|Saklad5]] ([[User talk:Saklad5|talk]]) 20:02, 9 December 2018 (UTC)

I wonder if it is possible to make a map projection stupid enough to support this at first glance. [[User:Saklad5|Saklad5]] ([[User talk:Saklad5|talk]]) 20:05, 9 December 2018 (UTC)

2057: Internal Monologues

2018-10-10T22:10:38Z

Saklad5: /* Explanation */ Removed the Bloomberg article from the examples of recently-discovered hacks, since it is incredibly dubious and likely fictional. There’s plenty of examples that are actually confirmed to choose from, anyway.

{{comic
| number = 2057
| date = October 10, 2018
| title = Internal Monologues
| image = internal_monologues.png
| titletext = Haha, just kidding, everyone's already been hacked. I wonder if today's the day we find out about it.
}}

==Explanation==
{{incomplete|Created by an internal monologue. Please edit the thoughts below until complete. Do NOT delete this tag too soon.}}

=== Botany ===
Most of the mass of trees is extracted from the air. [http://www.abc.net.au/radionational/programs/greatmomentsinscience/trees-are-made-from-air/9675642#transcript] More precisely: The bulk of the mass of a tree is composed of cellulose and water. Cellulose is a polysaccharide, that is, it's a large molecule consisting of many glucose molecules bonded together. Plants make those glucose molecules through photosynthesis: they make them by combining water and carbon dioxide molecules using the energy from sunlight. Plants get the carbon dioxide from the atmosphere, and arguably the water also as it usually comes from rain which is condensed water vapor.

=== Physics ===
{{w|Gravity}} is one of the four fundamental forces of physics. In everyday experience, most people tend to think of gravity merely as a pervasive downward force, but as a physicist, Cueball is more aware that in fact, all gravitational forces are mutual; any pair of objects will exert an equal and opposite gravitational force on each other, regardless of how big they are. Therefore, he is correct in saying that his phone and the Earth are being "pulled together", and finds it remarkable that he is able to sense this interaction between two objects of such an astronomically disparate size.

=== Computer Security ===
Anyone well versed in computer security understands just how insecure the systems that we depend on actually are.

In the title text it is noted that possibly all our systems are already hacked, and we just haven't found out yet. Since malicious hackers do their work covertly, a successful hack often isn't discovered until days, week, or even years later. By that time they may have successfully hacked many other systems using the same techniques and/or exploiting the same widely unknown or un-patched security flaws. Some recent high profile hacks recently discovered include a [[https://securitytoday.com/articles/2018/10/02/facebook-hacked-50-million-users-data-exposed.aspx 50-million user hack of Facebook]] and Google+ announcing they are [[https://www.blog.google/technology/safety-security/project-strobe/ shutting down the consumer side of Google+]] due to a security flaw they knew about months ago.

=== Graphic Design ===
{{w|Graphic designer}}s recognize fonts and design elements, and see how they come together. In this comic, the graphic designer wonders how the ''{{w|Law & Order}}'' font was chosen for a particular storefront's sign. ''Law & Order'' is a police procedural TV series created by Dick Wolf in 1990, which has had various spinoffs. The font used for the title sequence of ''Law & Order'' is called {{w|Friz Quadrata}}, and is also the font used for the signage of the New York Police Department headquarters.

=== Medicine ===
Doctors are well versed in human anatomy, and are likely to think about what is inside of people more than the average person would.

Talk:1701: Speed and Danger

2016-07-01T14:41:23Z

Saklad5:

I think this might be a strong contender for worst comic on xkcd. Although [[1384: Krypton]] definitely makes for stiff competition. [[Special:Contributions/108.162.216.102|108.162.216.102]] 14:28, 1 July 2016 (UTC)

1549: xkcd Phone 3

2015-07-13T05:58:44Z

Saklad5: Removed opinion on fingerprint scanners being unreliable, as iPhones are extremely reliable and consistent with Touch ID. (Perhaps the editor had only had experience with Samsung’s ripoff?)

{{comic
| number = 1549
| date = July 10, 2015
| title = XKCD Phone 3
| image = xkcd_phone_3.png
| titletext = If you're not completely satisfied with the phone after 30 days, we will return you to your home at no cost.
}}

==Explanation==
This is a follow-up to [[1363: xkcd Phone]] and [[1465: xkcd Phone 2]]. It parodies common smartphone specs by attributing absurd or useless features to a fictional phone.

{| class="wikitable"
!Feature
!Explanation
|-
|'''Ear screen'''
| An overcomplicated term for a speaker, connecting a screen which emits light to send visual information and the portion of a speaker which vibrates to send auditory information. Comparing the two makes a speaker a screen for the ear.
|-
|'''Heartbeat accelerator'''
| A mashup of heartbeat sensor and accelerometer. May be some sort of external pacemaker. If that's the case, it's worrying that it only accelerates, potentially causing a positive feedback (heart attack). It may also be the result of the phone being so exciting or frustrating that it increases its user's heart rate.
|-
|'''MobilePay money clip'''
| While mobile pay is a form of payment involving electronic transfers via cellphone, this model includes a money clip; a way of holding physical bills together, which defeats the purpose of electronic payment. Whether this is a clip that transfers money digitally or the phrase mobile pay is just a marketing tag is unknown.
|-
|'''Siri, or whoever it was we put in here'''
| A joke on intelligent personal assistants. It also jokes that Siri and the like are actual people, trapped inside of phones.
|-
|'''Instead of being on surface only, screen goes all the way through'''
| A reference to surface screens. Possible reference to smartphones with screen display wrapping one or more edges, like Samsung Galaxy Note Edge or Samsung Galaxy S6 Edge, or dual-screen smartphones with screen on the back (usually e-ink) like YotaPhone 2, or smartphones with minimal bezel like e.g. Sharp AQUOS Crystal.

Screen going ''all the way through'' would leave no place for innards of smartphone: processor, battery etc, and unless each layer is designed to be semi-transparent to see the inner {{w|voxel}}s the inner displays would be unseeable anyway.
|-
|'''theknot.com partnership: Phone licensed to perform wedding ceremonies and does so at random'''
| [https://www.theknot.com/ theknot.com] is a website that assists in all stages of wedding planning. Due to this partnering, the phone has apparently obtained legal status as a {{w|Justice of the peace}} capable of performing legally valid marriages. It exerts this capability randomly, however, so the phone's owner (or potentially any other unsuspecting bystander) could suddenly find themselves with a new spouse without their knowledge, generally an undesired effect. Whether this would result in unintentional {{w|bigamy}} or if the phone restricts itself to pairing up singles, or even enacts divorce first if necessary, is left unclear. May be a reference to how same-sex marriage was fully [http://en.wikipedia.org/wiki/Obergefell_v._Hodges legalized] in the United States just two weeks prior to the release of this comic.
|-
|'''Fingerprint randomizer'''
| Presumably randomises the user's fingerprint, which may or may not be inconvenient depending on the intent of the user. It is not clear whether the device will change the person's fingerprint into a human-like fingerprint that is randomly selected from all possibilities, or if it completely mangles the fingerprint of the user. Either way, physically altering the user's finger to this degree will likely involve a painful process. Likely a cynical reference to fingerprint scanners, which are touted as password replacements.
|-
|'''USB E (hotswappable)'''
| A USB port that makes fun of the three current systems, A, B, and recently C, by skipping D completely and jumping to E. The port presumably charges the phone and allows to transfer files like normal, but this kind lets you perform {{w|Hot swapping}} (replacing computer system components without turning the system off) with it, which has always been a feature of USB, so mentioning it is redundant at best.
May be a reference to the eSATAp (Power over eSATA) hybrid port that is functioning as a USB and eSATA port at the same time. The Serial ATA bus interface has standardized hot swapping support.
|-
|'''Waterproof, but can drown'''
| Perhaps a reference to Siri or the person trapped in the phone drowning, but the phone itself staying functional. This is another human-like function, which the first 2 XKCD Phone comics had.
|-
|'''Foretold by prophecy'''
| Likely mocking people on the internet who attempt to predict when Apple will release their next device. Might also be a joke on many videogames, in which the main character is 'the chosen one', because 'the prophecy' foretold it.
|-
|'''Runs Natively'''
| Usually a description given to ported software, as this statement doesn't make any sense when referring to hardware (notable {{w|Transmeta Crusoe|exceptions}} to the norm are few and far between). When software writers would like to run their apps on multiple platforms, they usually have three choices: re-compile the source code into each platform's codebase (often requiring tweaking to handle practical differences in resources between the systems); use a specially 'pre-portable' code that you can {{w|write once, run anywhere}}, such as Java, but requires a suitable interpreter to be written for each platform (and may still require code tweaks to absorb differences in implementations); create a specific emulator/virtual machine to allow existing code to 'see' the platform it was written for, despite the underlying system.
Only the first option is 'running natively', often the most optimised and thus best-performing option, and is usually qualified such as "Runs <Software Name> natively", for particular packages full compiled upon that platform. It would also make little sense for the OS ''itself'' to be non-native, except when intentionally emulating another system (ideally on a more powerful system that can power past the inefficiencies of conversion and translation).
Or, in this case, it may be that the phone has legs and can literally run.
|-
|'''Wristband'''
| Probably mocking trending smart watches, this feature would not be very useful on a full-sized smart phone, as it would be uncomfortable to wear due to its size.
|-
|'''Wireless discharging'''
| Many modern cellphones feature wireless charging, which uses electromagnetic induction to charge the battery of the device. This model, apparently uses the same technology to discharge the battery; which, of course is something undesired, as one needs the battery's energy to run the phone. May also refer to the standard behavior of the phone's antenna, which communicates wirelessly via EM radio waves, but discharges the battery in doing so. It could also be simply and literally describing the nature of all cell phones, and indeed all battery-powered electronic devices, to gradually use the battery (discharging) when there are no wires attached (wireless), since wireless also means no power cord is plugged in (and assuming the absence or non-use of the aforementioned wireless charging function, which this phone may not even have).
|-
|'''Magnetic stripe'''
| Likely a dig at the NFC (near-field communication) wireless radio modules in many modern phones. NFC allows, among others functions, mobile payment. This magnetic stripe could be a cheap way to imitate payment functionality, but "compatible" with classic credit cards.
Magnetic stripes are a data storage method used by devices such as credit cards and key cards to hold and transfer small amounts of information like key codes. Usually cellphones don't have them as they utilize more robust and protected ways to store and transmit data (such as NFC). The magnetic stripe shown would likely be unusable with current magnetic stripe readers due to the phone's thickness, in contrast to that of regular cards, thus breaking all imagined 'compatibility' arguments.
It would also be very annoying as it seems to block part of the screen.
|-
|'''2 AA batteries (not included)'''
| A phrase usually shown on small, low-powered, electronic devices like remote controllers, and not on cellphones; which use lithium-ion batteries and need to be constantly recharged for continuous use.
The apparently thin phone (according to the scale as judged by the wristband) would also preclude inserting AA batteries, unless a protruding battery compartment is hidden out of view on the back of the phone.
Alternatively could mean two Anti-Aircraft (artillery) "batteries" which would be large-caliber guns.
|-
|'''Boneless'''
| Reference to meat or fish products being boneless, i.e. having all the bones removed, making it convenient to cook or eat. Unclear why a phone would be boneless since it is mostly inedible, perhaps a reference to the person trapped inside having their bones removed to make them easier to fit inside, or stating that the phone is flexible. (A possible reference to the iPhone 6's reported problems with its chassis, where it {{w|IPhone 6#Chassis bending|could bend under pressure}})
Likely a reference to "Bone Conduction Microphones" implying that needing bones to work is a disadvantage and this phone has the feature of being "Boneless".
|}

The phrase "We made another one®©™" is a reference to how phone companies release new phones very often, and the trademarks that surround the phone itself.

The title text is a joke on guarantees and customer service. Usually the advertisement says that if the customer is not satisfied with the product, they'll refund the money and take the product back at no additional cost. In this case they guarantee the customer they'll send him/her home without charge; implying they won't fix or refund anything. Or that (due to anticipated but unspecified faults of some kind), the phone's owner will ''need'' help to get back home when things go wrong, and probably be thankful for such assistance, in yet another example of a worryingly non-specific 'reassurance'.

The singularity reference is worth explaining: The Singularity is a frequent trope in Science Fiction stories that postulates a time when AI technologies become all-pervasive, often alongside ubiquitous computing. This can include a situation where human minds can be uploaded into AIs, effectively running as simulations within these large distributed computers.

Someone needs to get on this and create a BOINC project or something. In all seriousness though, I wonder how many Tamagotchis you could simulate at once on the average home computer. [[User:Saklad5|Saklad5]] ([[User talk:Saklad5|talk]]) 14:55, 3 July 2015 (UTC)
