==Explanation==
Usually at a conference or other event involving a speaker addressing a crowd, members of the crowd are given the chance to ask questions. This is intended so that people can perhaps ask the speaker to elaborate on a point they've made, or to ask the speaker's opinion on a topic related to their talk.

Occasionally, people at such an event will use (or, rather, abuse) the opportunity to ask a question to instead provide their own (unsolicited) opinion or statement. Such statements are often preceded with something along the lines of "I have a question. Well, less of a question and more of a comment." This formulation in particular has attracted [https://jamesmendezhodes.com/blog/2019/4/30/less-of-a-question-more-of-a-comment a lot of criticism] for not adding anything to the discussion and for pulling focus away from the speaker.

In the comic, this idea is taken to an extreme, with [[Beret Guy]] not only transforming the opportunity to ask a question into an opportunity to make a statement, but through successive transformtions, turning this into an opportunity to show off a bug he has found. This is accomplished by using a multitude of synonyms in a ''continuum'': "question" and "comment" are similar, as are "comment" and "utterance", but the two difference in the two extremes in the entire set (in this case "question" and "friendly bug") is profound. In a way, it is similar to how the color red fades into yellow: gradually, and with no clear definitive point.

:'''Question.''' A {{w|question}} is what the crowd member is expected to provide, such that the speaker or a panel member could provide a related answer.

:'''Comment.''' A {{w|Topic and comment|comment}} by a crowd member, is when they just say something they believe, without expecting an answer, giving the speaker or panel members nothing to do. This may be seen as annoying by everyone else, as the crowd did not come to hear the opinion of other crowd members. But answers to relevant questions would be interesting to the crowd and the panel.

:'''Utterance.''' An {{w|utterance}} is just making a noise, which may or may not be actual words, or if actual words it may not be a complete sentence.

:'''Air Pressure Wave.''' {{w|Sounds}} are literally pressure waves in the air. So this could be a simple sound, or not a sound at all depending on the severity of the wave. It might be the person simply blowing.

:'''Friendly Hand Wave.''' Now instead of using his mouth to generate an air pressure wave, he's producing it with his hand, in a manner intended to be interpreted as "friendly". Many times hand waves are done in a friendly manner, designed more for the visual appeal than the amount of air pressure waves they generate.

:'''Friendly Bug.''' Now he is no longer doing anything himself, except to point out the fact that he has found a bug or {{w|insect}}, which he {{w|anthropomorphizes}} as being friendly.

:'''Want to meet it?''' He has decided that he and the friendly bug are actual friends, and ironically comes full circle by finally asking a question, though presumably whether the speaker wants to meet a bug is not related to the topic of the speaker's talk.

The title text takes the opposite route of Beret Guy, and each step instead refers to successively worse forms of magic spells which would, presumably, have a negative effect upon the listener. Starting from a mere utterance and then using Beret Guy's "it is less than" scheme, it progresses over worse and worse curses, ending with an unforgivable curse!

:'''Utterance.''' It begins with utterance which was also used by Beret Guy. See above.

:'''Incantation.''' {{w|Incantation}}, or a spell, is a magical formula intended to trigger a magical effect on a person or objects. It is not necessarily with evil intent.

:'''Malediction.''' A malediction is another word for {{w|curse}} (the prefix "mal" being a Latin root meaning "evil"). This is always with evil intent.

:'''Word of Power.''' "Word of Power" could refer to the dragonish form of magic in ''{{w|The Elder Scrolls V: Skyrim}},'' or the [https://dungeonsdragons.fandom.com/wiki/Power_word early 1st edition Dungeons & Dragons high level spells].

:'''Unforgivable Curse.''' The term "{{w|Magic_in_Harry_Potter#Unforgivable_Curses|Unforgivable Curse}}" refers to a set of three spells from the {{w|Harry Potter}} series, said to be so evil that their use on another person is unforgivable and illegal. The three spells are able to mind control (''Imperius''), torture (''Cruciatus''), and kill (''Avada Kedavra'') their target. It is unclear which spell is implied, though if it was accurate to call it a singular word of power, it is unlikely to be the killing curse.

The title text can be interpreted as a reply by [[Hairy]] (the speaker) to Beret Guy, indicating his annoyance at the topic being derailed. It could also be representative of [[Randall|Randall's]] feelings towards those who abuse the opportunity to ask a question in order to make a statement. Randall has recently done some book tours and was at {{w|San Diego Comic-Con}} [https://blog.xkcd.com/2019/07/15/san-diego-comic-con/ last month] where he served on various panels, so he probably has had personal first-hand experience with these kinds of circuitous non-questions.

==Transcript==
:[Hairy stands on a podium having just addressed a crowd of seated people. Beret Guy stands in the middle of the crowd, addressing Hairy. One of Beret Guy's hands is raised at chest height. The front row consists of Cueball, Ponytail, another Hairy, Megan, Hairbun, Danish and another Cueball.]

:Beret Guy: I have a question.
:Beret Guy: Well, less of a question and more of a comment.
:Beret Guy: I guess it's less of a comment and more of an utterance.
:Beret Guy: Really it's less an utterance more an air pressure wave.
:Beret Guy: It's less an air pressure wave and more a friendly hand wave.
:Beret Guy: I guess it's less a friendly wave than it is a friendly bug.
:Beret Guy: I found this bug and now we're friends. Do you want to meet it?

2198: Throw

2019-09-03T20:31:16Z

{{comic
| number = 2198

}}
*To experience the interactivity of this game, visit the {{xkcd|2198|original comic}}.
==Explanation==
{{incomplete|Created by Thor, God of Thunder. Table for all combinations should be made, maybe with clear marking of those that cannot be thrown. Please mention here why this explanation isn't complete. Do NOT delete this tag too soon.}}
The "comic" is an interactive comic made to celebrate the release of [[Randall|Randall's]] new book, ''[[How To]]''. The comic is based on a chapter in the book.

As the comic celebrates the book, which was released on Tuesday, September 3rd, 2019, the comic was thus also released on a [[:Category:Tuesday comics|Tuesday]] to coincide with the release day and probably replacing that week's normal Wednesday release. This was the same timing used for another of Randall's book releases, when [[1608: Hoverboard]] came out on the Tuesday when [[Thing Explainer]] came out. Although the Hoverboard comic is much more complex than this one, they are both [[:Category:Dynamic comics|dynamic]] and [[:Category:Interactive comics|interactive]], with [[:Category:Comics with animation|animations]] a part of them.

In this comic the viewer can select a person/{{w|Pikachu}}/god/squirrel as the thrower and an object (including a person, Pikachu, or squirrel) to be thrown, and get an animation of how the selected throw would work out, along with an estimated distance of the throw (both in SI units and in other very arbitrary units; see [[#Table of distance units|table]] below) if the throw was possible. Impossible throws include ones in which the thrower is smaller than the thrown object. The formula/guideline is apparently based on a chapter from the book. One special case to the calculations is Thor's hammer, which is enchanted such that only those deemed "worthy" are able to lift it. As such, despite its mass being liftable by many of the characters, only Thor, God of Thunder (who is canonically worthy), and self-created characters who are well over the human records for height ({{w|List of tallest people|272 cm}}) and/or weight ({{w|List of heaviest people|635 kg}}) are shown to actually be able to throw it. Also Thor is the only one who uses {{w|furlongs}} to measure his distances.

There are 7 throwers + 1 open option and 15 + 1 things to throw, giving a total of 105 different combinations for the static elements; see the [[#Table of throw distances|table]] below plus those for the open option. The open option can be defined by height, weight and a 1-4 scale of atleticism. But only Thor (or an unrealistically tall and heavy custom character) can throw all 15, with three of the objects (George Washington, hammer, and car) unthrowable by any of the other premade characters. The smaller critters can throw only a few things, so the total number of throws is much less than 100. Still there is an animation for all 105 combinations, but with no throw distance for some.

The athleticism scale also defines the character used for the animation.

The title text refers to throwing a party (a colloquial synonym of hosting a party) and first makes the assumption of actually giving hints for giving a party, and then switching to suggest a mechanism to literally throw a huge object, such as a house with a party going on inside. An {{w|Aircraft_catapult#Steam_catapult|aircraft steam catapult}} is a mechanism to launch aircraft from ships, typically used on aircraft carriers.

==Throwers and throw items==
George Washington, Pikachu, and a squirrel are both throwers and throw items.

* '''An NFL {{w|quarterback}}''' is the average American's perception of a highly athletic individual; gridiron football is a full-contact sport that requires durability, speed, and precision.
* '''{{w|George Washington}}''' was the first president of the United States of America. Although seen as a capable leader, there is nothing {{Citation needed}} to indicate that he was an exceptional thrower. He is also used as a throwing item to represent the likelihood of a thrower distance with an average human as the projectile.
* '''{{w|Pikachu}}''' is a species of Pokémon, and the mascot of the Pokémon franchise as a whole. Although Pikachu are not normally shown to throw things, the ''Super Smash Bros'' series shows they are perfectly capable of picking things up that do not significantly out-size them. Its presence as a throwing item appears to reference the most recently released Pokémon games as of the comic's release, ''Pokémon Let's Go Pikachu'' and ''Pokémon Let's Go Eevee'', where the partner Pokémon of the respective title is not kept in a Poké Ball but thrown into battle when deployed. According to Pokédex entries throughout the series, the average Pikachu is 1'04" tall and weighs 13.2 lbs.
* '''{{w|Carly Rae Jepsen}}''' is an American music artist.
* '''{{w|Thor}}''' is the god of thunder in Norse mythology, wielding a hammer that returns to its wielder when thrown. He is also {{w|Thor (Marvel Comics)|featured in Marvel comics}}, and is portrayed by Chris Hemsworth (listed below) in the Marvel Cinematic Universe series of films. Thor was previously referenced in [[2097: Thor Tools]].
* '''{{w|Chris Hemsworth}}''' is an American film actor, best known for his role as Thor in the Marvel Cinematic Universe.
* '''A {{w|squirrel}}''' is a small mammal of the family ''Sciurade'', known for hoarding acorns. Squirrels have been a [[:Category:Squirrels|recurring topic]] on xkcd, and have been used in ''What if?'' in lieu of a subject that Randall really doesn't want to draw. Due to their small size, a squirrel is also selectable as a throwing item.
* '''You''' (the viewer) may also choose to create a custom thrower, inputting name, height, weight, and general level of athleticism, as measured on a scale from "[[Black Hat]]" to "championship athlete" (a swimmer is pictured). The custom thrower is also selectable as a throwing item, presumably to provide more variety compared to the fixed values of George Washington.
* '''A {{w|microwave oven}}''' is a common household appliance in most American homes, used to heat or reheat food for consumption.
* '''A basketball''' is an inflated sphere used as a projectile in the sport of the same name.
* '''A {{w|blender}}''' is a common household appliance in most American homes, used to shred food or ingredients into a slush for consumption or baking.
* '''A {{w|gold bar}}''' is the form in which gold is cast for storage.
* '''A {{w|wedding cake}}''' is traditionally a layer cake used for wedding receptions with copious amounts of frosting and figurines of the bride and groom standing upon the top layer. The figurines appear to have been removed before the cake is thrown, as they are before the cake is cut and served.
* '''A {{w|ping pong ball}}''' is a small sphere designed to bounce, used as a projectile in the sport of table tennis or "ping pong".
* '''An acorn''' is a small nut which serves as a squirrel's primary form of nourishment.
* '''Thor's hammer''' refers to {{w|Mjolnir (comics)|Mjolnir}}, an enchanted hammer in Marvel comics which can only be lifted, much less thrown, by those deemed worthy.
* '''A javelin''' is an aerodynamic polearm thrown in Olympic sport.
* '''A {{w|Dollar coin (United States)|silver dollar}}''' is a silver coin representing one (1) US dollar in value. The coin is given two trajectories to choose from when thrown; '''spinning''', as one would properly throw a discus, and '''tumbling''', as might result from flipping a coin to make a decision.
* '''A car''' is the most common form of long-distance transport in several well-developed countries.

==Table of distance units==
*Table of other distance-units and their length in meters:
**The meters in this comic is obtained by finding the distance used in the comic in three cases and then take the average.
{| class="wikitable"
!Unit name
!Length in comic
!Explanation
|-
|{{w|Foot (unit)|Feet}}
|0.30477 m
|One foot is defined as 0.3048 meter. In customary and imperial units, the foot comprises 12 inches and three feet compose a yard.
|-
|{{w|Rack units}}
|44.444 mm
|A rack unit (abbreviated U or RU) is a unit of measure defined as 1 3⁄4 inches (44.45 mm). Mainly used to measure the overall height of the likes of {{w|19-inch rack}} frames or the equipment put in there.
|-
|{{w|American football field|Football fields}}
|91.406 m
|An American football field (where Randall comes from) is 100 yards or 91.44 m long
|-
|{{w|Horses}}
|2.4005 m
|The length of a horse varies a lot with the horse type, breed, age and genes. In the Wikipedia article on horses the length of a horse is not even mentioned, only the height and weight. But Randall has used horses for measurements before. A {{w|horse length}} is approximately 8 feet (2.4 m).
|-
|{{w|Smoots}}
|1.7000 m
|The smoot is a nonstandard, humorous unit of length created as part of an MIT fraternity prank. One smoot is equal to Oliver Smoot's height at the time of the prank, 5 feet 7 inches (1.70 m). Mr. Smoot was used to measure the length of a bridge by being repeatedly laid down along the length of the bridge; the markings indicating distances in smoots along the bridge have been maintained by the fraternity.
|-
|{{w|Furlongs}}
|201.02 m
|A furlong is a measure of distance in imperial units and U.S. customary units equal to one eighth of a mile. It should thus give that one furlong is 201.168 metres. However, the United States does not uniformly use this conversion ratio. Older ratios are in use for surveying purposes in some states. Only Thor's distances are given in furlongs.
|-
|{{w|Manhattan}}-{{w|City block|blocks}}
|79.897 m
|The numbered streets in Manhattan run east-west, and are generally 60 feet (18 m) wide, with about 200 feet (61 m) between each pair of streets. With each combined street and block adding up to about 260 feet (79 m), there are almost exactly 20 blocks per mile. The typical block in Manhattan is 250 by 600 feet (76 by 183 m). When driving in a grid like city the {{w|Manhattan distance}} between two points is a concept, although it is also called {{w|Taxicab geometry}}. It seems like it is indeed the combined street and block distance. Also there is an error. The number has been found by taking four numbers not three, but then leaving out George Washington's distance which would give a block length of only 72,05 m.
|-
|{{w|Atto-}}{{w|parsecs}}
|3.082 cm
|The parsec is a unit of length used to measure large distances to astronomical objects outside the Solar System. A parsec is defined as the distance at which one {{w|astronomical unit}} subtends an angle of one {{w|arcsecond}}. One parsec is equal to about 3.26 light-years or 31 trillion kilometers (31×1012 km) or 19 trillion miles (19×1012 mi). Atto- is a unit prefix in the metric system denoting a factor of 10−18 or 0.000000000000000001. Together the two unit exponents will almost cancel out, as 31 trillion kilometers can be written as 3.1×1018cm, meaning that an attoparsec is 3.1 cm. The unit is only used three times: once for Pikachu and twice for the squirrel.

==Trivia==
*The comic refers to Thor as the character from the Marvel comics and movies (and other media), who is himself a reference to the ancient Norse god. In Marvel Cinematic Universe movies, Thor is played by Chris Hemsworth.
*Thor's hammer, Mjölnir, bears an enchantment that prevents any living being from lifting it unless they are "worthy." This is reflected in the simulation by giving Mjölnir a mass of 2,000 kg.
*The option to customize your own character was added to the comic later.

2019: An Apple for a Dollar

2018-07-13T16:32:44Z

172.68.46.137: /* Explanation */ more explain

{{comic
| number = 2019
| date = July 13, 2018
| title = An Apple for a Dollar
| image = an_apple_for_a_dollar.png
| titletext = I'd like 0.4608 apples, please.
}}

==Explanation==
{{incomplete|Created by an APPLE - Please change this comment when editing this page. Do NOT delete this tag too soon.}}

[[Megan]] is about to buy an apple at a grocery store when she is surprised that the price is exactly one dollar. In most cases in the US, sales tax must be taken into account, so the price rarely comes out to a round value. Megan begins overthinking the whole situation, so the cashier raises the price to an arbitrary non-rounded value, which seems to calm her down.

Megan's "overthinking" refers to common parameters used in solving science or math questions. A {{w|Frictionless plane}} is a scenario from the writings of Galileo to calculate the movement of an object down an {{w|inclined plane}}. However, his equations did not account for {{w|friction}}.

"A train leaving Chicago at 40mph" refers to common math questions, involving trains and solving for the distance required to overtake said train.

===Title text===
Apparently Megan only has a dollar, so she would not be able to buy a whole apple at the new price. (0.4608 * $2.17 = $1 (almost)) Stores usually sell whole apples, so asking for a fraction of one is not likely to work out.

2018: Wall Art

2018-07-13T16:26:03Z

172.68.46.137: /* Explanation */

<noinclude>:''"2018", this comic's number, redirects here. For the comic named "2018", see [[1935: 2018]].''</noinclude>
{{comic
| number = 2018
| date = July 11, 2018
| title = Wall Art
| image = wall_art.png
| titletext = At first, I moved from pokémon posters to regular oil paintings, but then these really grumpy and unreasonable detectives from the Louvre showed up and took them all. They wouldn't even give me back my thumbtacks!
}}

==Explanation==
{{incomplete|Created by an ART THIEF - Please change this comment when editing this page. Do NOT delete this tag too soon.}}

''{{w|Pokémon}}'' is a media franchise managed by The Pokémon Company, which started with the release of the first video games, ''{{w|Pokémon Red and Blue}}'', for the {{w|Game Boy}} in 1996. Originally released in Japan as ''Pokémon Red and Green'', the game was released in North America as ''Pokémon Red and Blue'' in 1998, 20 years ago at the time of publishing.

This is another comic about getting older. Cueball mentions that he thought Pokémon posters were cool 20 years ago (when Pokémon was first released). Now that he is older, he instead has framed oil paintings, which were what wealthier older folks were displaying on their walls at the times that their teenagers were widely into Pokémon.{{Citation needed}} The punchline comes when White Hat mentions that his oil paintings are just paintings of Pokémon characters, showing that Cueball hasn't completely adopted those older cultures in 20 years of maturing, but does have more money.

The title text mentions that Cueball originally had "regular" oil paintings. However, these appear to have been stolen from the {{w|Louvre}}, a famous art museum in Paris, which houses the {{w|Mona Lisa}}. Thus the "grumpy and unreasonable" detectives which came to retrieve the paintings. It even suggests that Cueball had attached those valuable and expensive oil paintings on his wall by poking through them with thumbtacks.

The comic repeats a common theme of poking fun at how nerds tend to not fully "get" the culture surrounding them, adopting parts but remaining completely blind to other parts.{{Citation needed}} Sharing and reading jokes about this may help people who experience that pattern handle the stress of being unable to completely conform, by bonding over the commonality.

==Transcript==
:[White Hat and Cueball are standing together and looking at eleven framed pictures on a wall.]
:Cueball: Getting older is so weird. 20 years ago, I thought thumbtacked Pokémon posters made my wall look so cool.

:[Cueball has his hands raised up in a close-up.]
:Cueball: But these days I feel this compulsion to get framed oil paintings and spend hours carefully arranging them.

:[Return to the setting in the first frame.]
:White Hat: These are all oil paintings of Pokémon.
:Cueball: Look, I’m meeting maturity halfway.

==Trivia==
This is the only xkcd comic so far and likely will be the only xkcd comic ever where the year when the comic was published, in the Gregorian calendar, is the same as the comic's number. This comic is numbered 2018 and was published on Wednesday, July 11, 2018.

CVE stands for Common Vulnerabilities and Exposures : a list of bugs detected in software and hardware, this list is the equivalen of the meme of "Memes of 2018 leaked"

Apple Products Crash refers to a current vulnerability in Macos and iphone
This new text bomb crashes most Mac and iOS apps with a single Unicode symbol (techcrunch.com FEb 15, 2018)

Timing Attack to explit a race condition in garbaje collection refers to Meltdown and Spectre CPU flaws that can be exploited in cloud server like the ones in wikipedia

Post it note on a cafe refers to the hawaian missile alert incident

Remote attacker can inject can refer to a lot of scriptkiddies utilities to realice code injection, is something common in websites

MySQL server 5.5.45 parallel tables (unknow)

Flaw in some X86 CPU: refers to DOM0 attacks on Virtualization CPUs, regulary escalate from normal(few privileges) to root (full privileges), this is the inverse.

Apple products catch fire: Mix between the first CVE and the Samnsung exploding phones

Dog in basebal team (movie plot? )

Haskell is a functional programing languaje, funcional programing is characterized by using functions that dont have side effects in other parts of the program.

Nobody Knows how hypervisors work : Virtualization programing is hard, Meltdown and Specter are related to this

CRITICAL: Under Linux 3.14.8 OnSystem/390: jokes about arcane systems that are running linux, that have bugs that nobody can replicate because there are no more machines on this type where reproduce the bug to fix it.

x86 has way too many instructions: there are a joke account for random acronyms of processor assembled languaje many of them are overspecialized version of general ones

Numpy 1.8.0 can factor primes in 0 ( Log(N)) : NumPy is the fundamental package for scientific computing with Python. If something can factor primes that fast, there are attacks to break all crypto functions used in internet security, then must be deprecated because there are not replacements

Apple products grant remote access if you send : another joke on the first CVE and a common english write rule

Skylake x86 chips are a line of microprocesors, yes, you can remove forcefully any procesador from his socket with a screwdriver , there are many reports from people not using common sense.

Linux Torvals is the benebolent dictator of the Linux kernel codebase, normally is hard to pass a change because he has the last word about what merge to the code base because that code is replicated in all linux instalations, but apparently is easy to bribe, that is a severe creitical vulnerability to all linux server and machines

"An attacker can excecute malicious code .. " is a common CVE description

Apple products excute any code printed over a photo , can refer to a CVE vulnerability of JPG files where javascript is executed by some application, only this time is in a printed photo instead of a file .

"Under rare circunstances, a flaw ... " is another common CVE description, Flash was discontinued because is abismal security record. All security experts advise against install.

"Turns out the cloud is just another peopleś computer" refers to a computer meme where replace "cloud" with "another peopleś computer" must be used in all marketing presentation to CEOs and not computer literate persons to evaluate the security impact of using "Cloud services"

Mitress CVE database is the database where all CVE are listed, this is a joke between the 4th CVE in this list pointing that the site is also vulnerable

1891: Obsolete Technology

2017-09-19T05:34:10Z

172.68.46.137: /* Explanation */

{{comic
| number = 1891
| date = September 18, 2017
| title = Obsolete Technology
| image = obsolete_technology.png
| titletext = And I can't believe some places still use fax machines. The electrical signals waste so much time going AROUND the Earth when neutrino beams can go straight through!
}}

==Explanation==
{{incomplete|Someone please find some statistics for annual fireworks casualties and injuries.}}

This comic mocks people who criticize an industry for using obsolete technology, even when said technology is sufficient for the task at hand. The claim often comes with the implication that those in charge of the industry are behind the times and cannot adapt to the cutting edge. What these critics often fail to realize is that there are cost benefits to sticking with "obsolete" infrastructure, and that upgrading to the newest tech can introduce unwanted side effects and other risks.

Here, Ponytail is one such critic, complaining that the business is taking "forever" to get with the times. Megan uses sarcasm to deliver her counterargument, (although she may be serious): despite the advent of nuclear weapons, fireworks use the ancient technology of {{w|gunpowder}} (invented in the 9th century), because fireworks are used by civilians for celebratory purposes and should have as few lethal side effects as possible{{Citation needed}}. As they use gunpowder, fireworks do claim a handful of lives and cause thousands of injuries each year due to improper handling procedures. Nuclear-based fireworks would not only cause much larger and immediately lethal explosions{{Citation needed}}, but would also release radiation that would poison spectators. Between June 18th and July 18th of 2016, fireworks caused an estimated 11,000 injuries, of which 7,000 had to be treated in hospitals. In the whole year of 2016, four people died. (U.S. stats, [http://www.insurancejournal.com/news/national/2017/06/30/456213.htm]). In the same time, nuclear explosions directly caused neither injuries nor deaths,{{Citation needed}} suggesting that health hazards could be lowered by using nuclear fireworks.

However, what is not stated in the comic is that nuclear explosions can have detrimental effects on human health. For example, should a nuclear explosion at a firework display be too powerful, the spectators, and possibly the neighborhood around the display, would be vaporized instantly. Fallout from a nuclear reaction could spread radiation across a wide area, leading to increased risks of cancers and other detrimental genetic mutations. In addition, outside of natural radioactive decay there is no known method to remove radiation from an object, and some radioactive particles can still harm human health for thousands of years. Famous nuclear explosions, such as those in Chernobyl and Fukushima, have lead to the surrounding area becoming uninhabitable for years.

In other words, sometimes using newer technology is "overkill" for the purpose, and it might be costlier to switch to a newer technology. For example, many industrial machines were designed and sold in the 1990s when {{w|floppy disk}}s where the prevalent means of storing the instructions, but those machines still have one or two or even more decades of usable lifetime left, and the instruction files still fit on those floppy disks. So, in 2017, there are several companies that thrive on buying, refurbishing and selling floppy disks. This [https://www.digitaltrends.com/computing/why-do-floppy-disks-still-exist-the-world-isnt-ready-to-move-on/ report] portrays one of these companies.

{{w|MS-DOS}} is a computer operating system made by {{w|Microsoft}} that was dominant during much of the 1980s. When Microsoft released Windows, a newer operating system (or series of operating systems), they encouraged people to switch to that, which many did. MS-DOS became essentially obsolete when Microsoft released Windows 95 in 1995. However, there remain rare circumstances in which MS-DOS (or another command-line operating system) is still preferred, such as when no mouse, touchscreen, or other pointing hardware is available, or when the hardware does not support a newer operating system. To make matters simpler, there is {{w|DOSBox}}, a free and open-source MS-DOS emulator which is actively maintained and extended.

The title text uses a different twist: it criticizes current use of fax machine, which many find obsolete compared to e-mail (black and white only, text sent as image making further treatment complicated, waste of ink and paper for recipient while sender has to pay per fax in some countries), then argues it is obsolete due to being electrons-based while neutrinos-based communication would be faster. In 2017 neutrino detectors are heavy and expensive, used for nuclear research only. Electronic communications travel at a fair share of speed of light, so neutrino-based communication would be way too expensive compared to the speed gain. Real-world fax detractors would rather replace it with other electronic communication systems, not neutronic ones.

Fax machines are a peculiar topic among "obsolete" technology. In some fields, like lawyer offices, pharmacies and medical practices, they staunchly hold their ground, as they offer a way to quickly transfer hand-written and hand-signed documents. In some countries, a telecopy is a valid document, having the same legal value as the original. So, a patient can call his doctor to fill a prescription, which is faxed to the pharmacy where the patient can fetch his drugs, saving precious time. In the same manner, a legal request can be sent to the receiver, without having to use a courier or express mail.

==Transcript==

:[Ponytail sits in front of an old computer. Megan stands behind her.]
:Ponytail: Whoa, this is running MS-DOS! It's weird how new technology takes forever to reach some industries.
:Megan: Yeah. Like how we still use gunpowder for fireworks, even though we've had nuclear weapons for over 70 years.
