==Explanation==
{{incomplete|Created by a LIQUID LIGHTSABER - Please change this comment when editing this page. Do NOT delete this tag too soon.}}
A {{w|lightsaber}} is a beam-like sword weapon used by members of the {{w|Jedi}} order in the {{w|Star Wars}} franchise. This comic shows a lightsaber fight starting between two [[Cueball]]-like Jedi, one already presenting their blade in challenge and the second activating theirs in response. When the first strike is made between the two lightsabers, they seemingly meld together, with a bloop sound, like the beams are made of a liquid. This then causes the two light beams to be stuck to each other. In in-universe "technical documents", lightsabers are said to be made from magnetically-confined plasma, so perhaps the magnetic fields which were projected from each hilt have merged instead of repelling (or presenting as mutually impervious) as is usually expected.

This scene actually looks a lot like what happens between Harry Potter and Voldemort's wands in the end of the fourth book the {{w|Harry Potter and the Goblet of Fire|Goblet of Fire}}. Here two spells hit each other and connect the two wands, the wand holders then unable to release or disconnect the wands.

In this situation one Jedi tries to shake the beam, maybe to break the bond, but instead the wave travels down the combined beam to also shake the other Jedi's hand-held hilt. When the vibration dies down the other Jedi then tries to deactivate his lightsaber as an attempt to end the connection. But the retraction of the entire double-sized light beam into the handle (as seen in the movies) causes both of the Jedi to be drawn together where they collide together, forcefully enough to render them both unconscious. The connected lightsaber handles lie next to them on the ground.

The title text implies that such events are how {{w|Jedi}} romances start, comparing it to the famous "spaghetti scene" from the 1955 Disney animated movie ''{{w|Lady and the Tramp}}'' where the two titular characters unintentionally kiss after sharing a strand of spaghetti. In the Old Republic, Jedi were forbidden from entering into romantic relationships (and discouraged from forming attachments in general), but in the pre-Disney ''Star Wars Legends'' continuity of the Expanded Universe, Luke Skywalker and Mara Jade first met while fighting in the aftermath of the fall of the Empire, and then developed a romantic relationship.

Star Wars is a [[:Category:Star Wars|recurring theme]] on xkcd, and lightsabers have been prominently featured before in, for instance, [[1397: Luke]] and [[1433: Lightsaber]], where the problem with the physics of a light beam as a sword is shown. But in general light does not interact with light as {{w|photons}} are {{w|bosons}} and can thus pass through each other. Interference, yes, but two pure light beams cannot collide and bounce back as when two lightsabers collide. Also as the comic Lightsaber mentioned above shows, there is no compatible real-world way of confining a beam of light, making it stop after about a meter (or anywhere){{Dubious}} - see {{w|Optical cavity}}. So this is another time where [[Randall]] makes a joke about the physics of lightsabers.

==Transcript==
:[Two Cueball like Jedi are engaging each other in a duel using lightsabers over 12 panels of equal size, with sound effects as the only sound. In the first panel the left Jedi has his lightsaber extended holding it in both hand pointing towards the other, who at this time is just turning his lightsaber on.]
:''Tssssss''
:Click

:[Almost same position of the Jedi, but the right Jedi's lightsaber has now extended, making a sound. He is holding it up near his head in both hands]
:''Tsss''

:[Then they run towards each other and swing their lightsabers towards each other, two small arcs indicating the swing of the lightsabers.]

:[The two beams hit each other and connects at the middle in a big bloop of light, with drops of "light" jumping off both above and below the connected lightsabers. Both Jedi still holds on to their handles with both hands. A loud sound comes out of the connection:]
:''Bloop''

:[The Jedi stands still holding their handles. The beam is now forming a bow between the two handles.]

:[The left Jedi violently shakes his handle causing a wave to travel down the beam towards the right Jedi.]
:Shake shake

:[As the left Jedi's end of the beam comes to rest the wave travels all the way the right Jedi's handle causing his hands to shake, although a bit less than the original shake.]
:Shake shake

:[Back to the bow of light between them, but the beam is visibly still shaking, but no wave is traveling any longer.]

:[Same setting but the shaking has stopped. The right Jedi turns his lightsaber off on his handle with a sound:]
:Click

:[The beam of light is retracted quickly into the handle of the Jedi turning his lightsaber off. So quickly that the two Jedi, still holding on to their handles are pulled up in the air and towards each other as the sound of the beam turning off is heard. Lines indicate their movement and shadows on the ground beneath them indicate they are in the air.]
:''Zhhhiiiip''

:[When the beam is completely retracted the two handles collide and so do the heads of the two Jedi with a loud sound. They still hold on to their handles with both hands. They still hang in the air with shadows on the ground beneath them.]
:''Bonk''

:[In the final panel the two Jedi lie unconscious on the ground with their heads towards each other and with their arms stretched out towards each other. The connected handles lie between them.]

Talk:1728: Cron Mail

2016-09-02T21:13:52Z

108.162.250.156:

I think the "MAILTO" variable in "/etc/crontab" is meant, so only only cron-mails would go to this address, not all mails for the user

[[User:Rincewind|Rincewind]] ([[User talk:Rincewind|talk]]) 13:09, 2 September 2016 (UTC)

The huge question is whether adding an email message to crontab would result in cron producing even more mail - or whether it would cause cron to fail in some way. The latter would do damage by killing some (possibly critical) cron tasks - the former could rapidly fill up the hard drive with an exponentially-growing crontab. An intermediate situation would be that cron simply ignores the junk and continues to function as before - in which case Cueball's change will have little practical impact on disk space consumption - but probably gradually slow cron's crontab parser to a crawl, which would also have rather severe effects. On most Linux setups, the mail directories are on a different partition to /etc. There is often very little spare space on the partition with /etc on it - so it's likely that Cueball's change will eventually do terrible damage in that case too. [[Special:Contributions/162.158.69.98|162.158.69.98]] 14:42, 2 September 2016 (UTC)
:On my Mint/Ubuntu/Debian-based Linux system, adding junk to /etc/crontab put a message is /var/log/syslog about "cron[1495]: (*system*) ERROR (Syntax error, this crontab file will be ignored)". So it looks like appending garbage to the crontab will just break cron entirely (or at least those handled by /etc/crontab; it may be private cron and /etc/cron.d/* jobs may continue to run, but cron.hourly, cron.daily, and cron.weekly jobs on my system are initiated through /etc/crontab so they would not run with a broken /etc/crontab). I don't know if other non-Debian distributions have a cron that behaves differently, however. [[User:N0lqu|-boB]] ([[User talk:N0lqu|talk]]) 15:18, 2 September 2016 (UTC)
:Seems like it wouldn't break the existing stuff, they'd still get run and then cron would start parsing the noise and complaining - the "intermediate" situation, though the "export MAILTO" seems wrong. If Cueball did it in his .bashrc, it might get into some of *his* cron jobs but unless it's in /etc/crontab (and there, no "export" is needed/used), it wouldn't matter. His jobs probably wouldn't have rights to write to /etc/crontab either. [[Special:Contributions/173.245.48.73|173.245.48.73]] 17:09, 2 September 2016 (UTC)

The current explanation misses a part of the joke present in Cueball's last statement: he is considering the cron program to be somehow sentient and able to make a decision between sending the email (is it really important?) and its self-preservation by not trashing its own config file. He is thus daring cron to continue sending emails at the risk of 'self-destruction'.

- I also feel like the part of the joke is the cron has been sending him useless mail for 15 years. So now, he is sending cron useless mail

This states it can be run as infrequently as once a year, however by using February 29th, you can have it run once every 4 years (exc ever 100 inc every 400). But I think you might be able to get better by also setting it to run on a day of the week. e.g. February 29th, which is a Monday, which would then (after this year) not run for another 28 years, next running on February 29th, 2044.

Should that be noted in the article or is it a needless complication? (Also, I don't know what day of the week is what for this syntax).[[Special:Contributions/108.162.250.156|108.162.250.156]] 21:13, 2 September 2016 (UTC)

1701: Speed and Danger

2016-07-04T07:09:49Z

108.162.250.156:

{{comic

| titletext = NASCAR removed the passenger seats because drivers hated how astronauts kept riding along with them and loudly announcing "Ahh, what a nice and relaxing drive."
}}

==Explanation==
{{incomplete|More on the speed of sport cars and the race cars. How much faster does it feel for a human to see a regular sports car on a high way and then a formula one car. More on why a rocket seems slow?}}

In this {{w|scatter plot}} [[Randall]] plots the speed of several vehicles (including people on foot for "normal sports") and how disastrous a crash would be. The punchline is that space {{w|rocket}}s travel so dangerously fast, and crashes are so utterly catastrophic, that it pushes literally every other kind of crash to the "slow and safe" corner by comparison. (A similar punchline was used in the title text of [[388: Fuck Grapefruit]].)

With the plot Randall makes the observation that the danger of a crash is greatly influenced by its speed and highlights the concept of relativity between what we perceive as "fast," normal sports and two different types of racing cars, vs. a much faster vehicle, a rocket during launch. A rocket may appear to ascend slowly (and of course it begins its ascent slowly), but on the way to orbit it ends up moving very fast. But before it reaches the more extreme speed regime it will be far away from the ground (and the casual observer), where there is nothing to compare this speed to as opposed to a race car speeding by a spectator during a race. (Of course rockets are slow compared to the speed of light.)

Apart from the high speed, there is also the altitude to take into account for a rocket launch, and the vast amount of fuel needed to get into orbit, and any sort of catastrophic failure is almost certainly fatal.

Racing cars are often involved in crashes, but at that speed it is possible to construct them so even serious crashes may not be fatal. Although rockets are also made as safe as possible, it is a completely different regime of ''speed and danger'', and the risk of something going wrong during a take off is much higher, and it is impossible to prevent a lethal disaster if the launch fails during the ascent. This results in a much higher mortality rate for each crashed rocket (probably 100%) vs. crashed sports/race cars.

Rocket launches are compared to "normal {{w|sports}}" (presumably meaning people running approximately 25 km/h, and possibly also {{w|polo}} {{w|horse}}s galloping approximately 40 km/h), {{w|NASCAR}} (which reaches speed of 320 km/h), and {{w|Formula One}} (F1), where the fastest race cars go 380 km/h. Although peak speed for an F1 car is higher than NASCAR, the average lap speed is much lower as F1 tracks have slow corners while NASCAR ovals can be negotiated with much less speed variation. It is also arguable whether F1 is more dangerous than NASCAR - there have been fewer fatalities in F1 this millennium, though fewer cars compete and races are of shorter duration.

A rocket launched to reach the {{w|International Space Station|ISS}} needs to match the speed of the space station which moves at 27,600 km/h. A rocket that needs to {{w|Escape velocity|escape}} from Earth needs to reach 40,270 km/h, but so far no humans have escaped. However, the astronauts going to the Moon came close, with {{w|Apollo 10}} setting the {{w|List_of_spaceflight_records#Fastest|speed record}} for manned flights with 39,896 km/h. (It was only about [https://www.quora.com/Why-was-Apollo-10-the-fastest-of-all-the-Apollo-missions 0.4% faster] than the next 7 missions that, in contrast to Apollo 10, were supposed to land on the Moon). The lowest of the rocket speeds mentioned above is still more than 70 times as fast as the highest speed for race cars.

The title text serves to emphasize the point further, as an astronaut (used to the several G's of acceleration during takeoff and overall much higher speeds) would likely find a NASCAR car moving at ~300 km/h paltry compared to what they're acclimated and has supposedly aggravated NASCAR drivers by making a point of saying so. And thus this is used to explain why there are no passenger seats in NASCAR cars, to prevent astronauts from joining the drivers for a nice, slow ride.

Of the many [[:Category:Charts|charts in xkcd]] this one is notable for containing the fewest sample points of any [[:Category:Scatter plots|scatter plots]] in xkcd.

The comic is also (deliberately?) imprecise. Speed and danger do not extend infinitely in both directions. For instance, another way to show the dat would be:

982: Set Theory

108.162.250.156: Wood-chipping the set defines an ordering on it ...

{{comic
| number = 982
| date = November 25, 2011
| title = Set Theory
| image = set_theory.png
| titletext = Proof of Zermelo's well-ordering theorem given the Axiom of Choice: 1: Take S to be any set. 2: When I reach step three, if S hasn't managed to find a well-ordering relation for itself, I'll feed it into this wood chipper. 3: Hey, look, S is well-ordered.
}}

==Explanation==
This comic is a pun on the phrase "{{w|Proof by Intimidation}}" which normally is a jocular term used mainly in mathematics. It refers to a style of presenting a purported mathematical proof by giving an argument loaded with jargon and appeals to obscure results, so that the audience is simply obliged to accept it, lest they have to admit their ignorance and lack of understanding.

However, in this comic, "Proof by Intimidation" is taken to mean that by intimidating the elements within a set, they will conform to the proof (or, as the title text says, they will become "well-ordered"). This is accomplished by believing that the elements can be {{w|anthropomorphize}}d such that they feel fear. The idea of executing as an example was exemplified by Sun Tzu in the ancient book {{w|The Art Of War}}.

The {{w|axiom of choice}} (which has been referenced in [[:Category:Axiom of Choice|previous xkcds]]) says that given any collection of bins, each containing at least one object, it is possible to make a selection of exactly one object from each bin.

In the title text, the well-ordering theorem states that every set can be well-ordered. A set X is well-ordered by a strict total order if every non-empty subset of X has a least element under the ordering. This is also known as {{w|Zermelo's theorem}} and is equivalent to the Axiom of Choice. The woodchipper is a reference to the 1996 film {{w|Fargo (film)}}, where a character uses one to dispose of a body.

There is another layer to the joke. If you can feed the set to the wood-chipper, that defines an ordering on the set (the order in which the elements are fed to the wood chipper) which would be well-ordered. Hey, look, the set really is well-ordered! If there were no way of defining a well-ordering on the set, you wouldn't be able to feed it to the wood-chipper.

With complex software, this is a long and tiring process, so when the product is finally finished no one dares to modify it any further for fear that it will fail in unexpected ways. After some time passes, it is even worse because nobody really remembers how the software was ''supposed'' to work, so the product becomes some kind of godlike treasure which must be treated with the utmost respect and reverence because, you know, if it stops working we're all doomed ([[1421: Future Self]]). After completion, {{w|Refactoring}} is the process of rewriting code for greater efficiency or reliability. However, if the performance is not 'too bad' (i.e. not unusably terrible in normal use) there is a great temptation to avoid this, in favour of the 'if it ain't broke, don't fix it' methodology. This could lead, for example, to a trained monkey and an abacus being used to crunch numbers. It works, but could be done far better. However, nobody wishes to change it, for fear of breaking a presently functional, if inefficient, system.

Triply-Nested Docker
| |
{{w|Docker (software)|Docker}} allows complete operating system to run under different operating system (OS) (with some performance penalty). Triply-nested docker would mean OS A running under OS B running under OS C running under OS D (running under OS E?). That would likely be a performance and management nightmare

Paravirtual Boy®
| |
This is a reference to the {{w|Virtual Boy}}, a failed portable console created by {{w|Nintendo}}. {{w|Paravirtualization}} is a common buzzword in the virtualization community these days. "Virtual X" means simulated X. "Paravirtual X" means X is simulated, but is aware of simulation and cooperating, for faster performance.

A dev typing real fast
| |
A dev is a {{w|Software developer|software developer}}. This is possibly a reference to [[341: 1337: Part 1]], where [[Mrs. Roberts]] edits the {{w|Transmission Control Protocol|TCP}} stream live while wearing oven mitts and baking cookies. Such a feat would require real fast typing. It looks like xkcd webserver is not a computer after all -- we have a person manually replying to HTTP protocol queries. I guess she's busy.

|-
| |
Older version of our software
| |
People are often reluctant to switch to newer versions of software because, even though newer versions are supposed to have more features and fewer bugs, they end up confusing users. Users of older versions are used to doing everything with less features and circumventing old bugs. They don't know how to use the new features, which of course come with new bugs they haven't learned how to circumvent yet. It is also often the case that newer versions remove weird unused old features, breaking the workflow of users who actually did use such features and are left without a suitable replacement ([[1172: Workflow]].

Mystery Networking Horror

Randall suggests here that the whole networking stuff behind the XKCD service is both mysterious (no one actually knows the details) and horrific (technically questionable architecture and implementation, or somehow tentacled and eldritch in nature).

Microsoft Bob Server®
| |
{{w|Microsoft Bob}} was a short-lived, failed attempt by Microsoft, around 1995, to provide a user-friendly interface for the {{w|Microsoft Windows|Windows}} 3.1x, Windows 95 and Windows NT operating systems. It consisted of a virtual "house" and "rooms", and the idea was that you could click on a pen and open the word processor. It was heavily criticized and was soon discontinued. Randall seems to be making the suggestion the Bob has continued to be developed and now there's a Bob Server, similarly to Windows server.

A giant {{w|Central processing unit|CPU}} someone built in Minecraft
| |
{{w|Minecraft}} is a popular sandbox game where you place blocks to build things. Since the introduction of Redstone objects (materials used to create basic electric circuits within the game) people have made many machines within Minecraft, including calculators and clocks. The most complex of these machines simulate simple computers, capable of storing several lines of code and performing basic mathematical operations such as division, which requires thousands of blocks and extremely complex designs.

The title text contains several jokes about the Java programming language:

* First, it refers to Java both as {{w|Sun Microsystems|Sun}} Java and {{w|Macromedia}} Java. This is a pun on the fact that older documents refer to "Sun Java" where newer documents refer to "{{w|Oracle Corporation|Oracle}} Java", as if there were two different languages. The fact is that Java was designed originally by Sun and then bought by Oracle, so it "changed name" even though the language is the same. Macromedia was the company that developed Flash before it was bought by Adobe. Both Flash and Java were popular in the early WWW to have interactive web pages, but both are being deprecated in favor of JavaScript.

* Second, the version numbers: older software products used to have two version numbers: major and minor (e.g. in {{w|MS-DOS}} 6.22 the major number is 6 and the minor is 22). Newer products tend to have hundreds of minor revisions, all of them numbered, so a typical user may well find themselves updating version 6.0.0.1 to 7.3.8.1 without knowing at all the differences between both versions or which other versions are in between. The ¾ in the Macromedia Java version is a joke on complex version numbers, which (so far) have never included fractions. It also can be reference to [http://harrypotter.wikia.com/wiki/Platform_Nine_and_Three-Quarters platform 9 ¾].

* Third, the 32-bit or 48-bit version: The {{w|Intel 80386}} processor used an architecture known as {{w|IA-32}}, which implies the data bus is 32-bit wide and thus able to handle up to 4{{w|Gibibyte|GiB}} of {{w|Random-access memory|RAM}} memory. This was plenty for the early 1990s, when a typical home PC would have about 8MiB (this is 512 times less than 4GiB). However, about 10 years after that, a typical home PC could well use more than 4GiB of RAM, so several 64-bit architectures were created. These architectures are not compatible, so programs (including the Java Runtime Environment, or JRE) often have 32-bit and 64-bit versions. Furthermore, the JRE is heavily used by many web browsers, and for this to work the JRE and browser need to be the same "number of bits". This means that most people have installed both versions of the JRE to be able to use it with both 32-bit and 64-bit browsers. There's no 48-bit architecture (though some 64-bit processors including the {{w|x86-64|most common ones}} don't actually USE all 64 bits everywhere, ignoring some bits so actual virtual or physical memory is smaller (in case of most common one, 48bits virtual and 40bits physical), they simulate a full 64-bit environment to allow adding more bits later, so there are no specific 48-bit applications).

* Fourth, an application trying to let the user install a new version of the JRE should direct the user to the download page in the [http://java.com/ java.com site], not to the main page which deals with lots of issues with java and is not particularly helpful when trying to update the JRE.

* Fifth, and continuing with the joke of users updating from 7.3.8.1¾ to 6.0.0.1 and not knowing why they should, the new version is said to "run fine but not really change anything". This is the usual behavior for Java updates: they run fine (possibly in opposition to [[1197: All Adobe Updates]], where updating must be done several times and the user is never sure they have installed all the newest updates), but after finished updating the user can't see any difference with the previous behavior, and/or may still be told that an update is required. Considering that 7.3.8.1¾ is bigger number than 6.0.0.1, it can also refer to the fact that the test for upgrading is incorrect and 7.3.8.1¾ is actually newer version.

* Sixth, Macromedia was a multimedia software company in the 90s that originally developed Flash, a popular plug-in similar to Java. Adobe purchased Macromedia in 2005.

168: Reverse Euphemisms

2016-01-04T11:34:13Z

108.162.250.156: The comic may well be a bad example of a dysphemism, but it is not a bad example of a colloquial "Reverse Euphemism" as described by the title and obvious joke at hand. Moved the linguistic definition of "Reverse Ephamism" to the end.

{{comic
| number = 168
| date = October 9, 2006
| title = Reverse Euphemisms
| image = reverse euphemisms.png
| titletext = I'm still waiting for a chance to use 'I have to see a man about a horse'.
}}

==Explanation==
{{w|Euphemisms}} are figures of speech used in place of more offensive terms. In this comic, [[Cueball]] uses swear words in the place of benign terms, inverting the typical usage of euphemisms. To "drop the kids off at the pool" is a euphemism meaning to "go take a shit." In this case, however, Cueball actually has to drop kids off at the pool but instead uses "go take a shit." Cueball is using the euphemism in reverse, hence the title.

In the title text, the figure is waiting for a situation in which he has to see a man concerning a horse, as this relates to another euphemism meaning to urinate. It can be assumed that, when telling someone about seeing the man about the horse, he would say "...then I had to go take a piss."

A reverse euphemism is actually called a dysphemism in linguistics, although this comic is actually a terrible example of this. Euphemisms are used to make a statement less offensive or disturbing without actually changing the underlying meaning, such as by using "pass away" instead of "die." A better example of a dysphemism would be "I have to drop off my dumbshit kids at the fucking pool".

1602: Linguistics Club

2015-11-12T01:30:40Z

108.162.250.156:

{{comic
| number = 1602
| date = November 11, 2015
| title = Linguistics Club
| image = linguistics_club.png
| titletext = If that's too easy, you could try joining Tautology Club, which meets on the date of the Tautology Club meeting.
}}

==Explanation==
A "[[wiktionary:sesquiannual|sesquiannual]]" meeting is one that occurs one and a half times every year, or once every 8 months. It comes from the Latin prefix "[[wiktionary:sesqui|sesqui-]]", which means "one and a half times", and "[[wiktionary:annual|annual]]", which means "happening once every year". This is not to be confused with [[wiktionary:sesquiennial|sesquiennial]], which means every one and a half years, or 18 months. A linguist or Latin scholar, the joke suggests, should be able to figure sesquiannual out as "half-and-one every year". This is an extension of the common confusion between "biannual," meaning "twice a year", and "biennial", meaning "once every two years". Compare with the {{w|Sesquicentennial Exposition}} celebrating the first 1½ centuries of the United States.

On the other hand [and the crux of the comic in general], 'sesqui' can be interpreted as a prefix meaning '1.5'. For example, the US sesquicentennial was celebrated on July 4, 1926 (after 150 years), so the confusion comes from people who think the meetings would be every 8 months (as above) or every 18 months (here). The confusion is related to the distinction between 'biweekly' (which paradoxically means either twice per week or once every two weeks) and 'semiweekly' (once every half-week, i.e., twice a week), and bimonthly (twice a month or every two months). 'Biannual' and 'biennial' only furthers this confusion (as in this case, 'biannual' and 'semiannual' are synonymous when the prefixes usually are not).

Regarding the title text, a {{w|tautology (rhetoric)|tautology}} is a statement that is true (or self-evident) because of its logical form, such as "all birds are birds" or "A = A." As such, the statement "the Tautology Club meets on the date of the Tautology Club's meeting" is itself tautological.

While the membership requirement for the original club is merely to know the intended frequency (presumably then a successful applicant to be told at least one meeting date in the cycle so that an attendance can be made; or perhaps the member is supposed to guess that by reasoning that every third meeting must extend across the beginning of a new year), Tautology Club's stipulation appears to require an eligible member to derive a valid meeting date from thin air without any clue at all (and no indication that there is even a regular cycle of any kind). This would definitely be more of a challenge.

The title text has a connection to [[703: Honor Societies]] in which Cueball announces that "the first rule of Tautology Club is the first rule of Tautology Club."

979: Wisdom of the Ancients

2015-03-15T16:54:46Z

108.162.250.156: Reworded part of the transcript - he's shaking the screen, not the computer

{{comic
| number = 979
| date = November 18, 2011
| title = Wisdom of the Ancients
| image = wisdom_of_the_ancients.png
| titletext = All long help threads should have a sticky globally-editable post at the top saying 'DEAR PEOPLE FROM THE FUTURE: Here's what we've figured out so far ...'
}}

==Explanation==
This comic refers to a common experience that those trying to solve tech problems have. Typically, people search on Google to try to find solutions to the problem. Sometimes the solution can be found on a software program's website, but the most helpful solutions frequently come from discussions on message boards, particularly for more obscure problems. This is because the odds are rather high that someone else, years ago, had the same problem you're having and resolved it.

However, in this comic, [[Cueball]] is unable to find any mention of the problem he's currently facing except for one forum post about it that did not include the problem's solution. This is akin to finding an FAQ with questions but no answers.

The title is a satirical reference to the notion that the "ancients," i.e. from thousands of years ago, possessed knowledge that has been lost to the centuries (such as exactly how Stonehenge was built), and that artifacts from those times do not fully divulge such knowledge. The fact that the "ancient" referred to in the comic is from 2003 (only 8 years before the comic was published) is an exaggeration of the feeling that the forum poster is lost to the sands of time, but in some sense this feeling is nonetheless true, since Cueball is unlikely to be able to contact him.

The title text is a suggestion to forums to be aware of the fact that people are likely going to come across such posts in the future and therefore to provide handy summaries of the most helpful conclusions of long threads for them, since combing through several false starts and failed attempts to resolve a problem can be quite tedious.

Putting in my own two bits, my first thought reading the title text was that she had a pacemaker. The fact that there were plutoniu pacemakers and the fact he mentioned that they were "in her middle" make me think "pacemaker". But I digress. As far as the "too much zinc", ??? [[Special:Contributions/199.27.128.186|199.27.128.186]] 02:20, 24 February 2015 (UTC)

Not sure if it's an inspiration, but this is an example of people not knowing what common human experiences they are missing (see: http://slatestarcodex.com/2014/03/17/what-universal-human-experiences-are-you-missing-without-realizing-it/). Also, "or she was the victim of unethical medical experimentation. Thus the probable reason for his abnormality." is ridiculous - no amount of medical experimentation will cause this. The probable reason for his abnormality is magic. [[Special:Contributions/108.162.241.17|108.162.241.17]] 15:35, 23 February 2015 (UTC)

I believe that the "Too Much Zinc?" - is an answer to what might be wrong with him, not a retort to Megan's tone. In fact, zinc is linked to eyesight, see for instance https://www.nei.nih.gov/news/pressreleases/101201 and other sources, and this "zinc overdose" might be believed by white beret guy to relate to his "super-human" eyesight?

The link to the UPPU club (You Pee Pu) appears to be broken. EDIT: fixed now, thanks whoever fixed it. {{unsigned ip|108.162.249.181}}

Did anyone else notice that this is the second comic in a row about elementary particles? I suspect a series coming up. [[User:Mikemk|Mikemk]] ([[User talk:Mikemk|talk]]) 21:48, 23 February 2015 (UTC)

Pacemakers are usually implanted round the clavicle, so I'm not satisfied with the theory that the plutonium is from a pacemaker. [[Special:Contributions/141.101.104.46|141.101.104.46]] 08:40, 24 February 2015 (UTC)

108.162.250.156: Respond to oddball theory with oddball response

I believe that the "Too Much Zinc?" - is an answer to what might be wrong with him, not a retort to Megan's tone.

"My dad FORM the dog"? Typo in the actual comic or just the wiki?

plutonium = radiation exposure, or pacemaker?
: Radiation exposure wouldn't give you plutonium, maybe the byproducts of its fission. I'm thinking that, whatever it is, it mutated Beret Guy in the womb, hence why he has this strange superpower.--[[User:Druid816|Druid816]] ([[User talk:Druid816|talk]]) 06:52, 23 February 2015 (UTC)

this guy sees by which elements are contained, not by which visible light?

Are the elements actually representing their atomic symbols? Be, O, S, Z? Not sure what the metal-in-the-face comment is about.

Perhaps the plutonium is coming from his mother smoking? [[Special:Contributions/141.101.99.102|141.101.99.102]] 08:51, 23 February 2015 (UTC)

He can't distinguish Dad and Dog, so he wasn't a genious back then. So what if the Plutonium wasn't a super complex mysterium, just one of the most important things for an infant, her breasts (in this case maby big ons).

I agree with 141.101.80.53. Beret Guy is answering Megan's question about what is wrong with him, not being arrogant. Arrogant would be out of character for Beret Guy, but giving an unusual answer to a rhetorical question would be true to character.

Perhaps too oddball a theory, but maybe his mom was actually a spacecraft powered by plutonium (e.g. [[Wikipedia:Galileo (spacecraft)#Electrical_power | Galileo(spacecraft)]]), making his father a planet and the dog a moon.
