Since Kate Dopingscandal has a bike, it seems to me she's actually likely a direct reference to Lance Armstrong. [[User:NiceGuy1|NiceGuy1]] ([[User talk:NiceGuy1|talk]]) 05:46, 20 July 2018 (UTC)

It's worth noting that the all-star right fielder for the Boston Red Sox, who are currently in first place in the MLB, is named Markus Lynn "Mookie" Betts, with the initials "MLB." Aside from the fact that he's already won several divisional titles with his team, there's a good chance he'll soon be on a world series winning team as well, perhaps to become the next high-profile example.

}}

==Explanation==
{{incomplete|Seems to be finished, but holds a pro-docker bias. Should be updated to include both the pro-docker and anti-docker interpretations of the comic; see discussion. Do NOT delete this tag too soon.}}

{{w|Docker (software)|Docker}} is a computer program that performs operating-system-level virtualization also known as containerization. It is developed by Docker, Inc. [[White Hat]] notices that many people are using Docker for "everything," implying that he does not understand what all the fuss is about. [[Cueball]] then explains the fundamental idea behind Docker with a simple story.

He notes how difficult it can be to combine two programs and have them work together as one. This is something all programmers can relate to. His specific example is to get two separate programs to display side-by-side on a tablet. The main joke is that Cueball's solution is a surprising twist to solving the problem. Instead of writing a lot of complicated code to deal with the problem at hand, he sidesteps the problem by using two separate devices, literally gluing them together. Docker uses the same general idea but the "glue" and the "multiple computers" are done in software, instead of literally gluing two computers together.

Cueball states that he achieved "software enlightenment" when he "solved" the problem by sidestepping it.

White Hat's initial confusion comes from the fact that Cueball did not write any software, yet achieved "software enlightenment." A good programmer doesn't necessarily need to be able to write programs or even understand how they work, provided that he/she has the skills needed to combine existing programs to solve tasks. An alternate interpretation is that someone with little programming experience could create a working program simply by copy/pasting code snippets from a coding forum such as StackOverflow and "gluing" them together without really understanding how they work.

The title text makes a joke about developers writing code for use in a Docker environment. The ideal is to only write "microservices" which are modules that do just one thing and do it well. The joke here is that even when a module does many different things, you can pretend it is a "microservice" by just ignoring all of it's features but one (hopefully the one that it does well).

==Transcript==
:[White Hat is sitting at a laptop. Cueball is standing behind him.]
:White Hat: Man, Docker is being used for everything.
:White Hat: I don't know how I feel about it.
:Cueball: Story time!

:[Cueball is standing by himself.]
:Cueball: Once, long ago, I wanted to use an old tablet as a wall display.

:[A picture of Cueball's imagined tablet with two applications open side by side. The app on the left is "LiveCam".]
:Cueball: I had an app and a calendar webpage that I wanted to show side by side, but the OS didn't have split-screen support.
:Cueball: So I decided to build my own app.

:[White Hat and Cueball as before, but White Hat has turned to face Cueball.]
:Cueball: I downloaded the SDK and the IDE, registered as a developer, and started reading the language's docs.

:[A picture of two smartphones glued together side by side, held on a backing board. The same two applications shown earlier are open on different phones.]
:Cueball: ...Then I realized it would be '''way''' easier to get two smaller phones on eBay and glue them together.
:Cueball: On that day, I achieved software enlightenment.

:[White Hat and Cueball still facing each other, with White Hat's arm resting on the back of the chair.]
:White Hat: But you never learned to write software.
:Cueball: No, I just learned how to glue together stuff that I don't understand.
:White Hat: I...OK, fair.

:Pretty much a description of all my "useful" programs. {{unsigned|Linker}}

I feel the thrust of this comic is partly “people use docker because they don’t know how to do things properly”; notably such people get tasks done easier and faster, but their work involves wasting a lot of computing reaources to do small tasks inside entire emulated systems. Agree? Disagree? [[Special:Contributions/162.158.62.153|162.158.62.153]] 18:59, 2 May 2018 (UTC)

I don't know if its just docker, almost any time I've gone to build mobile anything the API needs new libraries, their "secure" connecting functions must be used, or some other blackbox MUST be /glued/ to my work. If I don't stay on top of every platform, this in and of itself is a head ache I can't imagine what it'd be like if I had to learn and comply with the content of these libraries. {{unsigned ip|172.69.90.40}}

When did any tablet with a browser not support <tt><nowiki><frame></nowiki></tt>s and <tt><nowiki><iframe></nowiki></tt>s? And for that matter why are docker containers with kubernetes better than server images with a load balancer? I asked one large-shop sysadmin who had transitioned to the former from the latter, and he said, "There really aren't many differences but I feel like I'm ready for microservices."

:The issue as I see it is to get the two apps to both run simultaneously and appear side by side, which probably involves either writing code to control the window manager or getting the existing apps to output to an image that can be drawn on screen. I'm not a mobile developer, but my guess is that this would be quite difficult for a novice programmer.[[User:Probably not Douglas Hofstadter|Probably not Douglas Hofstadter]] ([[User talk:Probably not Douglas Hofstadter|talk]]) 23:13, 3 May 2018 (UTC)

For some reason, this really, really, REALLY feels like it's a continuation of 1987. Agree? Disagree? Also, the 'wasting a lot of computing resources to do small tasks inside entire emulated systems' does not feel like valid criticism, since they are just walled-in processes sharing the same kernel (and everything below). Firing up full-blown separate VMs for things that could just as well run in containers is the real wasteful choice IMHO. [[Special:Contributions/162.158.238.70|162.158.238.70]] 07:29, 3 May 2018 (UTC)
:Agree. 1987 shows how problematic Python can be due to its lack of a well thought out version control. How can you avoid this mess? Docker! It isn't the only way, but IMHO the most elegant solution. And yes, I have created docker containers where the sole purpose was to avoid contaminating an existing Python installation.

: Don't get mobbed by the docker marketers! I guess a lot of people use Docker today, but to me the comic reads as a criticism. I feel the real joy of programming is diving deep into components to learn how they work and connecting them in the most elegant, efficient ways possible (real 'hacking'). Using scripts, macros, and containers does not demonstrate to me an understanding of the real function of the components being used, and working without this understanding is inevitably going to lead to unexpected behavior somewhere later (problems, bugs, vulnerabilities) because you don't really know what your pieces are doing. I think the push for people to ignore these things is causing a 'dumbing down' of software workers that we should resist. I think a great use of containers is security isolation or build environment testing ... not software design. [[Special:Contributions/172.68.54.106|172.68.54.106]] 10:51, 4 May 2018 (UTC)

:: I agree about the "real joy" of getting to understand how some software works. Just like with mountain climbing. Using a helicopter to get to the top is much simpler and much more convenient. ''It also has a higher chance of success.'' But it sort of removes the joy. On the other hand, if you do programming for a living you might need to choose the helicopter. Your comment about "really know what your pieces are doing" is absolutely true. But note the wording here: ''what'' and not necessarily ''how''. If you need to know that module X and module Y are difficult to combine because they were built against different versions of library Z then you have gone too far. [[User:Epsilon|Epsilon]] ([[User talk:Epsilon|talk]]) 07:31, 5 May 2018 (UTC)
::: I like the helicopter analogy. Similar to the comic, it somewhat plays to both camps. The provider of the helicopter flight plans can tell people how to get to the mountaintop with little investment of effort to reach a high degree of success. However, people using this service take on the increased burden of providing for an expensive helicopter and its fuel. The provider of maps, instructions, and training to climb the mountain easily and reliably has invested in more effort, but the service they provide requires far fewer capital resources from the user to climb the mountain over and over. A difference here is that helicopters are very fast, whereas spinning up containers to execute a task will actually be slower than the alternative. Another thing those who code for the joy of it will talk about, is the value of investing one-time work up-front so that repeated tasks are made simpler later. But obviously people who need to reach deadlines that have been set too early to "do the work properly" will not be able to do this. Either module X or Y needs to be updated to work with the newer version of library Z. The older version likely has bugs and vulnerabilities. By not updating it, you are passing these problems on to your users. [[Special:Contributions/172.68.54.22|172.68.54.22]] 10:55, 5 May 2018 (UTC)

Is it worth adding that "achieved enlightenment" is probably a reference to http://www.thecodelesscode.com/?

The idea behind docker is that you do ''not'' glue together small code snippets. Whether from StackOverflow or elsewhere. What you are gluing together is in effect entire machines with software already installed. You normally don't know or care about any details finer than that. Not even which operating system the code was written for, which computer language it was written in, or whether the software has some odd and specific requirements about what else is installed on that machine. It is true that many programmers that copy snippets from StackOverflow don't really understand what those snippets are doing. But if you view this comic as an explanation of what Docker is all about, a reference to "copying small code snippets" seems to miss the point.

1930: Calendar Facts

| title = Calendar Facts
| image = calendar_facts.png
| titletext = While it may seem like trivia, it (causes huge headaches for software developers / is taken advantage of by high-speed traders / triggered the 2003 Northeast Blackout / has to be corrected for by GPS satellites / is now recognized as a major cause of World War I).
}}

==Explanation==
{{incomplete|Still missing a couple of explanations under "Consequences". Do NOT delete this tag too soon.}}
[[Randall]] presents what appears to be a generator of 156,000 facts [20 x 13 x (8 + 6 x 7) x 12], about calendars, most of which are false or have little meaning{{Citation needed}}. The facts are seeded by a mishmash of common tidbits about the time of year.

The formula for each generated fact goes as follows: "Did you know that '''[a recurring event]''' '''[occurs in an unusual manner]''' because of '''[phenomena or political decisions]'''? Apparently '''[wild card statement]'''."

This is [[:Category:Supermoon|the fifth time]] that Randall has referred to the phenomenon of a {{w|supermoon}}, which he typically makes fun of, most prominently in [[1394: Superm*n]].

The title text continues the chart with supposed real-life consequences of the trivia in the comic.

There are multiple online generators of Calendar 'facts' using this formula [https://www.pibweb.com/xkcd_calendar.php here] and [http://yahel.com/calendarfacts/ here].

==Table==
{| class="wikitable"
! Entry
! What it is
! Relation to other entries
|-
! colspan="3" | Recurring Events
|-
| The [Fall/Spring] {{w|Equinox}}
| The time of year at which the apparent position of the overhead sun passes the equator. During the equinox, the time that the Sun is above the horizon is 12 hours across the globe.
| Before the adoption of the {{w|Gregorian calendar}} in 1582, the equinoxes fell on earlier and earlier dates as the centuries went by, due to the {{w|Julian calendar}} year being 365.25 days on average compared to the tropical Earth year of 365.2422 days. {{w|Pope Gregory}}'s decision to remove the leap days on years that were multiples of 100 but not 400 corrected the average length of the calendar year to 365.2425 days.
|-
| The [Winter/Summer] {{w|Solstice}}
| The time of year when the apparent position of the overhead sun reaches its most extreme latitude. During the Winter and Summer solstices the days are the shortest and longest respectively.
| Similar to the equinoxes, the solstices were also falling on earlier dates every year before the Gregorian calendar.
|-
| The [Winter/Summer] {{w|Olympics}}
| The Olympic Games occur during the summer and the winter, alternating between the two seasons every two years.
| The Olympic Games do not have any set dates, and seem to only be included humorously as something else that alternates between occurring during the summer and winter.
|-
| The [latest/earliest] [sunset/sunrise]
| The extremes of times that the sun crosses a horizon according to a clock that keeps a fixed 24 hours as opposed to varying with the sun like a sundial.
| The latest sunset and earliest sunrise occur around the summer solstice; the latest sunrise and earliest sunset occur around the winter solstice. They do not occur exactly on these dates due to the {{w|equation of time}} causing drift in the times that sunsets and sunrises occur.
|-
| Daylight [saving/savings] time
| {{w|Daylight saving time}}, commonly referred to as daylight savings time, is the practice of setting clocks ahead, typically by one hour, during the summer months of the year.
| Daylight saving time will push the time of certain events such as sunrise and sunset past their "natural" times. For example, solar noon will occur around 1:00 PM instead of 12:00 noon when daylight saving time is active, making it the "wrong" time.
|-
| Leap [day/year]
| Because the durations of celestial events are not generally nice multiples of each other, they will tend to fall out of sync with each other. Leap days are days inserted into specific years to bring the calendar back into sync, and the years on which these {{w|leap day}}s occur are called {{w|leap year}}s.
|
|-
| {{w|Easter}}
| Easter is a holiday celebrating the death and resurrection of {{w|Jesus}}. It is defined as the Sunday after the first full moon after the spring equinox. This complicated formula has a long tradition behind it, known as {{w|Computus}}.
| When Pope Gregory decided to change the calendar in 1582, it was because the spring equinox was putting Easter on unexpectedly early dates.
|-
| The [harvest/super/blood] moon
|
* The {{w|harvest moon}} is the full moon that appears closest to the autumnal equinox.
* The {{w|supermoon}} is a phenomenon in which the moon is full at its closest approach to the Earth.
* The {{w|blood moon}} is a moon that appears tinted red during a total lunar eclipse because of light refracted from the Earth's atmosphere. It can also refer to the {{w|hunter's moon}}, the full moon directly after the harvest moon.
| Each of these lunar events happens approximately once a year.
* The harvest moon appears exactly once because it has a particular definition based on the time of year.
* The cycle of the distance of the full moon lasts about 13.5 months (14 full moons). However, because a supermoon is defined as any full moon that is within 10 percent of the closest relative distance possible (with 0 being perigee and 1 being apogee), it happens multiple times a cycle, for a total of usually 3 to 4 times per year.
* The blood moon during a lunar eclipse appears between zero to two times a year. The hunter's moon appears exactly once like the harvest moon.
|-
| Toyota Truck Month
| Toyota offers a discount for {{w|Toyota Tacoma|Tacoma}} trucks one month a year. Mainly notable because radio and television ads hype this discount up as "Toyota Truck Month".
|
|-
| {{w|Shark Week}}
| Every year, the {{w|Discovery Channel}} dedicates a week during the summer to programming featuring or about sharks.
|
|-
! colspan="3" | Unusual manners in which the events occur
|-
| happens [earlier/later/at the wrong time] every year
| colspan="2" | The solstices and equinoxes happened earlier every year ''before'' the decree by Pope Gregory in 1582. The earliest sunrise happens one hour later than it "should" happen due to daylight saving time having turned the clocks forward one hour.
|-
| drifts out of sync with the [sun/moon]
| colspan="2" | The Sun and Moon are generally what calendars are based on. If something were to drift out of sync, some corrective mechanism would have to be put in to put it back. This is the motivation behind leap years, leap months (in countries with lunisolar calendars) and leap seconds.
|-
| drifts out of sync with the zodiac
| colspan="2" | The dates on which the Sun crosses the constellations in the traditional zodiac has shifted in the past centuries due to the precession of the Earth's axis. In the period of time traditionally known as {{w|Aries}} (March 21–April 20), for example, the Sun actually points to {{w|Pisces}} instead.
|-
| drifts out of sync with the [Gregorian/Mayan/lunar/iPhone] calendar
| colspan="2" |
*The {{w|Gregorian calendar}} is a solar calendar with a mean calendar year length of 365.2425 days.
*The {{w|Mayan calendar}} is based on two cycles or counts, with a 260-day count combined with a 365-day "vague" solar year.
*A {{w|lunar calendar}} is based on Moon's phases, with each {{w|lunation}} being approximately 29.5 days, and a lunar year lasting roughly 354 days. An example of a lunar calendar is the {{w|Islamic calendar}}.
*The {{w|iPhone calendar}} is listed humorously due to its data synchronization issues.
|-
| drifts out of sync with the atomic clock in {{w|Colorado}}
| colspan="2" |
{{w|NIST-F1}} is an {{w|Atomic clock}} used as a reference for official time in the USA.
|-
| might [not happen/happen twice] this year
| colspan="2" | Some events may have a period of slightly more or slightly less than one year. If an event has a period of slightly less than one year (e.g. the Islamic calendar), it can occur twice in the same year (e.g. the year 2000 had two {{w|Eid al-Fitr}}s—one on January 8, and one on December 28). If an event has a period of slightly more than one year, there can be a year in which it does not occur at all, instead occurring near the end of the previous year and the beginning of the next.
|-
! colspan="3" | Cause (phenomena or political decisions)
|-
| time zone legislation in [Indiana/Arizona/Russia]
| Some states or provinces have time zone legislation that sets the standard time to something other than what the natural longitude of that location would suggest.
|
* The state of {{w|Arizona}} generally does not observe daylight saving time, keeping their clocks on {{w|UTC-7:00}} Mountain Standard Time year round. However, the {{w|Navajo nation}} reservation inside Arizona does observe it, causing the two regions to have different times in the summer and the same time in the winter.
* Time zones in Russia are all one hour ahead of what their longitude would suggest, which puts them in a "permanent" state of daylight saving time. (For example, {{w|St. Petersburg}} is 30°E, which means that its natural time zone is {{w|UTC+2:00}}, but its time zone is actually {{w|UTC+3:00}}.) From 1981 until 2011 Russia used to have the daylight saving time on top of it as well. The other changes include the abolition of the one-hour shift in 1991 and a return it back in 1992, and an increase to two hours in 2011 and a restoration back to one hour in 2014.
* {{w|Indiana}} has {{w|Time in Indiana|a complicated history}} with daylight saving time, likely related to the state being split between two time zones.
|-
| a decree by the Pope in the 1500s
| In 1582, Pope Gregory introduced the Gregorian Calendar, the calendar we use today, to replace the Julian Calendar. The calendar applied retroactively to the birth of Jesus Christ, which means that they had to skip 10 days, going straight from October 4 to October 15, 1582, during the switchover.
| The introduction of the Gregorian calendar brought Easter and the dates that months started back in sync with what they were in the 3rd century AD.
|-
| the precession of
| The Earth's axis is slowly changing position, in a phenomenon called the {{w|Axial precession|precession of the equinoxes}}.
| The precession of the equinoxes causes the seasons to occur about 20 minutes earlier than would be expected with the Earth's position relative to the stars, which could be construed as the equinox happening "later every year" if you use the stars as your frame of reference.
|-
| the libration of
| The Moon is {{w|tidal locking|tidally locked}} to its orbit around the Earth, which means that the same side of it tends to face the Earth at any given point in time. However, there are slight variations in the angle over the course of a month, which are known as {{w|libration}}.
| The libration of the Moon does not affect anything else in the chart, and seems only be included humorously as another example of a celestial phenomenon.
|-
| the nutation of
| Besides precession, there is also a smaller wobbling effect called {{w|Astronomical nutation|nutation}}.
|
|-
| the libation of
| A {{w|libation}} is a drink, often used in the context of a ritual offering of liquid to a deity by pouring it onto the ground or into something that collects it.
| This entry seems to have been included simply as a humorous misspelling of the word "libration". Certainly libation of any of the entities listed would be inadvisable.{{Citation needed}}
|-
| the eccentricity of
| Orbital eccentricity is the deviation of a body's orbit from a perfect circle. Orbital travel is faster when it's closer to the body being orbited and slower when farther away.
| The Earth's eccentric orbit causes the equinoxes and solstices to occur at irregular intervals. For example, summer in the northern hemisphere lasted 93 days in 2017, while fall only lasted 90 days.
|-
| the obliquity of
| The tilt of the Earth's axis relative to the ecliptic is also known as its obliquity.
|
|-
| the Moon
| The Moon is the primary satellite of the Earth.
|
|-
| the Sun
| The Sun is the star that the Earth orbits around.
| The Sun is the basis for many timekeeping events, such as the day and year.{{Citation needed}}
|-
| the Earth's axis
| The Earth's axis of rotation defines the Geographic North and South Pole, as well as the lines of latitude.
|
|-
| the Equator
| The Equator is the line on the Earth's surface which is equidistant from both poles of the Earth's axis.
|
|-
| the Prime Meridian
| The Prime Meridian is the line that starts at the geographic North Pole, runs through the {{w|Royal Observatory, Greenwich|Greenwich Royal Observatory}} in London, and ends at the South Pole. It is the basis for longitude when calculating coordinates for positions on the surface of the Earth.
| The Prime Meridian (and in particular the Greenwich Observatory) gives us Greenwich Mean Time (GMT), which is the basis for UTC and the time zone system.
|-
| the International Date Line
| The International Date Line is a line on the opposite side of the Earth as the Prime Meridian that separates regions that use time set behind UTC versus regions that are set ahead of UTC. It has many irregularities due to political changes that put certain countries or islands on either side of the divide contrary to their natural longitude.
| The irregular shape of the International Date Line means that certain regions of the Pacific Ocean (such as Kiribati) are more than 24 hours ahead of some other regions (such as Baker Island and American Samoa), which may cause problems with timekeeping.
|-
| the Mason-Dixon Line
| The Mason-Dixon line is a line delineating a portion of the border between Pennsylvania, Maryland, and Delaware.
| The Mason-Dixon line is included as a humorous example as another imaginary geographic line.
|-
| magnetic field reversal
| The Earth's magnetic field has been reversed several times in its geologic history, so that what we would currently call the "magnetic North Pole" was near the geographic South Pole about 780,000 years ago, before the most recent reversal.

| an arbitrary decision by Benjamin Franklin
| Benjamin Franklin wrote [http://www.webexhibits.org/daylightsaving/franklin3.html a letter to the Journal of Paris in 1784] in which he advised them to rise with the sun in order to save candlelight, after he observed that the Parisians were getting up at the same time by the clock and burning a lot of candles in the winter as a result.
An "arbitrary decision by Benjamin Franklin" also likely refers humorously to Franklin having defined positive charge to be that which is left on a glass rod by rubbing it with silk. As described in [[567: Urgent Mission]], this had the unfortunate consequence of assigning a negative value to the charge of the electron, which was later identified as the fundamental carrier of electric charge.
| Benjamin Franklin is often touted as "the father of daylight saving time", despite him never actually proposing to alter the clocks.
|-
| an arbitrary decision by Isaac Newton
| Possibly a reference to how Newton divided the colour spectrum into the now-familiar seven colours of the rainbow, on a somewhat arbitrary basis. Newton did spend time working on the problem of calendar reform, but it's unlikely that any decisions he made as a result would affect anything, since he never published his work, and by the time it gained attention the Gregorian Calendar had been widely adopted.
| The spectrum fact is one of those standard bits of trivia of the kind the chart alludes to. Although it has nothing to do with time-keeping, Newton is the sort of person who seems like he should have made decisions like this.
|-
| an arbitrary decision by FDR
| Franklin Delano Roosevelt set all time zones one hour ahead year-round during World War II. The law was repealed after the war ended.
Additionally, he changed the date of Thanksgiving from the last Thursday in November to the fourth Thursday in November as a way to increase the length of the Christmas shopping season in some years.
| Setting the time permanently one hour ahead would make everything happen at the "wrong" time celestially.

* Reduce the duration of daylight saving time back to its original span, or further.
* Eliminate daylight saving time altogether, going back to using standard time.
* Abolish daylight saving time but advance the time zone by one hour, effectively instating daylight saving time year round. This was done during World War II.
* Abolish daylight saving time and advance the time zone by 30 minutes, splitting the difference between the current standard time and daylight saving time.
* Reduce the number of time zones in the United States to two, consolidating Pacific time into Mountain time (UTC-7:00), and Eastern time into Central time (UTC-6:00).

At best, these time zone proposals will be fraught with controversy, with both sides arguing for the benefits of their time system. Some proposals, such as the 30-minute and 20-minute suggestions, would put the minute hands of the entire United States out of sync with the rest of the world, defeating the purpose of time zones with hourly UTC offsets in the first place, which could be construed as "making things worse".

1930: Calendar Facts

2018-01-12T17:15:48Z

172.68.54.22: /* Examples of true complete statements */

{{comic
| number = 1930
| date = December 18, 2017
| title = Calendar Facts
| image = calendar_facts.png
| titletext = While it may seem like trivia, it (causes huge headaches for software developers / is taken advantage of by high-speed traders / triggered the 2003 Northeast Blackout / has to be corrected for by GPS satellites / is now recognized as a major cause of World War I).
}}

==Explanation==
{{incomplete|Still missing a couple of explanations under "Consequences". Do NOT delete this tag too soon.}}
[[Randall]] presents what appears to be a generator of 156,000 facts [20 x 13 x (8 + 6 x 7) x 12], about calendars, most of which are false or have little meaning{{Citation needed}}. The facts are seeded by a mishmash of common tidbits about the time of year.

The formula for each generated fact goes as follows: "Did you know that '''[a recurring event]''' '''[occurs in an unusual manner]''' because of '''[phenomena or political decisions]'''? Apparently '''[wild card statement]'''."

This is [[:Category:Supermoon|the fifth time]] that Randall has referred to the phenomenon of a {{w|supermoon}}, which he typically makes fun of, most prominently in [[1394: Superm*n]].

The title text continues the chart with supposed real-life consequences of the trivia in the comic.

There are multiple online generators of Calendar 'facts' using this formula [https://www.pibweb.com/xkcd_calendar.php here] and [http://yahel.com/calendarfacts/ here].

==Table==
{| class="wikitable"
! Entry
! What it is
! Relation to other entries
|-
! colspan="3" | Recurring Events
|-
| The [Fall/Spring] {{w|Equinox}}
| The time of year at which the apparent position of the overhead sun passes the equator. During the equinox, the time that the Sun is above the horizon is 12 hours across the globe.
| Before the adoption of the {{w|Gregorian calendar}} in 1582, the equinoxes fell on earlier and earlier dates as the centuries went by, due to the {{w|Julian calendar}} year being 365.25 days on average compared to the tropical Earth year of 365.2422 days. {{w|Pope Gregory}}'s decision to remove the leap days on years that were multiples of 100 but not 400 corrected the average length of the calendar year to 365.2425 days.
|-
| The [Winter/Summer] {{w|Solstice}}
| The time of year when the apparent position of the overhead sun reaches its most extreme latitude. During the Winter and Summer solstices the days are the shortest and longest respectively.
| Similar to the equinoxes, the solstices were also falling on earlier dates every year before the Gregorian calendar.
|-
| The [Winter/Summer] {{w|Olympics}}
| The Olympic Games occur during the summer and the winter, alternating between the two seasons every two years.
| The Olympic Games do not have any set dates, and seem to only be included humorously as something else that alternates between occurring during the summer and winter.
|-
| The [latest/earliest] [sunset/sunrise]
| The extremes of times that the sun crosses a horizon according to a clock that keeps a fixed 24 hours as opposed to varying with the sun like a sundial.
| The latest sunset and earliest sunrise occur around the summer solstice; the latest sunrise and earliest sunset occur around the winter solstice. They do not occur exactly on these dates due to the {{w|equation of time}} causing drift in the times that sunsets and sunrises occur.
|-
| Daylight [saving/savings] time
| {{w|Daylight saving time}}, commonly referred to as daylight savings time, is the practice of setting clocks ahead, typically by one hour, during the summer months of the year.
| Daylight saving time will push the time of certain events such as sunrise and sunset past their "natural" times. For example, solar noon will occur around 1:00 PM instead of 12:00 noon when daylight saving time is active, making it the "wrong" time.
|-
| Leap [day/year]
| Because the durations of celestial events are not generally nice multiples of each other, they will tend to fall out of sync with each other. Leap days are days inserted into specific years to bring the calendar back into sync, and the years on which these {{w|leap day}}s occur are called {{w|leap year}}s.
|
|-
| {{w|Easter}}
| Easter is a holiday celebrating the death and resurrection of {{w|Jesus}}. It is defined as the Sunday after the first full moon after the spring equinox. This complicated formula has a long tradition behind it, known as {{w|Computus}}.
| When Pope Gregory decided to change the calendar in 1582, it was because the spring equinox was putting Easter on unexpectedly early dates.
|-
| The [harvest/super/blood] moon
|
* The {{w|harvest moon}} is the full moon that appears closest to the autumnal equinox.
* The {{w|supermoon}} is a phenomenon in which the moon is full at its closest approach to the Earth.
* The {{w|blood moon}} is a moon that appears tinted red during a total lunar eclipse because of light refracted from the Earth's atmosphere. It can also refer to the {{w|hunter's moon}}, the full moon directly after the harvest moon.
| Each of these lunar events happens approximately once a year.
* The harvest moon appears exactly once because it has a particular definition based on the time of year.
* The cycle of the distance of the full moon lasts about 13.5 months (14 full moons). However, because a supermoon is defined as any full moon that is within 10 percent of the closest relative distance possible (with 0 being perigee and 1 being apogee), it happens multiple times a cycle, for a total of usually 3 to 4 times per year.
* The blood moon during a lunar eclipse appears between zero to two times a year. The hunter's moon appears exactly once like the harvest moon.
|-
| Toyota Truck Month
| Toyota offers a discount for {{w|Toyota Tacoma|Tacoma}} trucks one month a year. Mainly notable because radio and television ads hype this discount up as "Toyota Truck Month".
|
|-
| {{w|Shark Week}}
| Every year, the {{w|Discovery Channel}} dedicates a week during the summer to programming featuring or about sharks.
|
|-
! colspan="3" | Unusual manners in which the events occur
|-
| happens [earlier/later/at the wrong time] every year
| colspan="2" | The solstices and equinoxes happened earlier every year ''before'' the decree by Pope Gregory in 1582. The earliest sunrise happens one hour later than it "should" happen due to daylight saving time having turned the clocks forward one hour.
|-
| drifts out of sync with the [sun/moon]
| colspan="2" | The Sun and Moon are generally what calendars are based on. If something were to drift out of sync, some corrective mechanism would have to be put in to put it back. This is the motivation behind leap years, leap months (in countries with lunisolar calendars) and leap seconds.
|-
| drifts out of sync with the zodiac
| colspan="2" | The dates on which the Sun crosses the constellations in the traditional zodiac has shifted in the past centuries due to the precession of the Earth's axis. In the period of time traditionally known as {{w|Aries}} (March 21–April 20), for example, the Sun actually points to {{w|Pisces}} instead.
|-
| drifts out of sync with the [Gregorian/Mayan/lunar/iPhone] calendar
| colspan="2" |
*The {{w|Gregorian calendar}} is a solar calendar with a mean calendar year length of 365.2425 days.
*The {{w|Mayan calendar}} is based on two cycles or counts, with a 260-day count combined with a 365-day "vague" solar year.
*A {{w|lunar calendar}} is based on Moon's phases, with each {{w|lunation}} being approximately 29.5 days, and a lunar year lasting roughly 354 days. An example of a lunar calendar is the {{w|Islamic calendar}}.
*The {{w|iPhone calendar}} is listed humorously due to its data synchronization issues.
|-
| drifts out of sync with the atomic clock in {{w|Colorado}}
| colspan="2" |
{{w|NIST-F1}} is an {{w|Atomic clock}} used as a reference for official time in the USA.
|-
| might [not happen/happen twice] this year
| colspan="2" | Some events may have a period of slightly more or slightly less than one year. If an event has a period of slightly less than one year (e.g. the Islamic calendar), it can occur twice in the same year (e.g. the year 2000 had two {{w|Eid al-Fitr}}s—one on January 8, and one on December 28). If an event has a period of slightly more than one year, there can be a year in which it does not occur at all, instead occurring near the end of the previous year and the beginning of the next.
|-
! colspan="3" | Cause (phenomena or political decisions)
|-
| time zone legislation in [Indiana/Arizona/Russia]
| Some states or provinces have time zone legislation that sets the standard time to something other than what the natural longitude of that location would suggest.
|
* The state of {{w|Arizona}} generally does not observe daylight saving time, keeping their clocks on {{w|UTC-7:00}} Mountain Standard Time year round. However, the {{w|Navajo nation}} reservation inside Arizona does observe it, causing the two regions to have different times in the summer and the same time in the winter.
* Time zones in Russia are all one hour ahead of what their longitude would suggest, which puts them in a "permanent" state of daylight saving time. (For example, {{w|St. Petersburg}} is 30°E, which means that its natural time zone is {{w|UTC+2:00}}, but its time zone is actually {{w|UTC+3:00}}.) From 1981 until 2011 Russia used to have the daylight saving time on top of it as well. The other changes include the abolition of the one-hour shift in 1991 and a return it back in 1992, and an increase to two hours in 2011 and a restoration back to one hour in 2014.
* {{w|Indiana}} has {{w|Time in Indiana|a complicated history}} with daylight saving time, likely related to the state being split between two time zones.
|-
| a decree by the Pope in the 1500s
| In 1582, Pope Gregory introduced the Gregorian Calendar, the calendar we use today, to replace the Julian Calendar. The calendar applied retroactively to the birth of Jesus Christ, which means that they had to skip 10 days, going straight from October 4 to October 15, 1582, during the switchover.
| The introduction of the Gregorian calendar brought Easter and the dates that months started back in sync with what they were in the 3rd century AD.
|-
| the precession of
| The Earth's axis is slowly changing position, in a phenomenon called the {{w|Axial precession|precession of the equinoxes}}.
| The precession of the equinoxes causes the seasons to occur about 20 minutes earlier than would be expected with the Earth's position relative to the stars, which could be construed as the equinox happening "later every year" if you use the stars as your frame of reference.
|-
| the libration of
| The Moon is {{w|tidal locking|tidally locked}} to its orbit around the Earth, which means that the same side of it tends to face the Earth at any given point in time. However, there are slight variations in the angle over the course of a month, which are known as {{w|libration}}.
| The libration of the Moon does not affect anything else in the chart, and seems only be included humorously as another example of a celestial phenomenon.
|-
| the nutation of
| Besides precession, there is also a smaller wobbling effect called {{w|Astronomical nutation|nutation}}.
|
|-
| the libation of
| A {{w|libation}} is a drink, often used in the context of a ritual offering of liquid to a deity by pouring it onto the ground or into something that collects it.
| This entry seems to have been included simply as a humorous misspelling of the word "libration". Certainly libation of any of the entities listed would be inadvisable.{{Citation needed}}
|-
| the eccentricity of
| Orbital eccentricity is the deviation of a body's orbit from a perfect circle. Orbital travel is faster when it's closer to the body being orbited and slower when farther away.
| The Earth's eccentric orbit causes the equinoxes and solstices to occur at irregular intervals. For example, summer in the northern hemisphere lasted 93 days in 2017, while fall only lasted 90 days.
|-
| the obliquity of
| The tilt of the Earth's axis relative to the ecliptic is also known as its obliquity.
|
|-
| the Moon
| The Moon is the primary satellite of the Earth.
|
|-
| the Sun
| The Sun is the star that the Earth orbits around.
| The Sun is the basis for many timekeeping events, such as the day and year.{{Citation needed}}
|-
| the Earth's axis
| The Earth's axis of rotation defines the Geographic North and South Pole, as well as the lines of latitude.
|
|-
| the Equator
| The Equator is the line on the Earth's surface which is equidistant from both poles of the Earth's axis.
|
|-
| the Prime Meridian
| The Prime Meridian is the line that starts at the geographic North Pole, runs through the {{w|Royal Observatory, Greenwich|Greenwich Royal Observatory}} in London, and ends at the South Pole. It is the basis for longitude when calculating coordinates for positions on the surface of the Earth.
| The Prime Meridian (and in particular the Greenwich Observatory) gives us Greenwich Mean Time (GMT), which is the basis for UTC and the time zone system.
|-
| the International Date Line
| The International Date Line is a line on the opposite side of the Earth as the Prime Meridian that separates regions that use time set behind UTC versus regions that are set ahead of UTC. It has many irregularities due to political changes that put certain countries or islands on either side of the divide contrary to their natural longitude.
| The irregular shape of the International Date Line means that certain regions of the Pacific Ocean (such as Kiribati) are more than 24 hours ahead of some other regions (such as Baker Island and American Samoa), which may cause problems with timekeeping.
|-
| the Mason-Dixon Line
| The Mason-Dixon line is a line delineating a portion of the border between Pennsylvania, Maryland, and Delaware.
| The Mason-Dixon line is included as a humorous example as another imaginary geographic line.
|-
| magnetic field reversal
| The Earth's magnetic field has been reversed several times in its geologic history, so that what we would currently call the "magnetic North Pole" was near the geographic South Pole about 780,000 years ago, before the most recent reversal.
|
|-
| an arbitrary decision by Benjamin Franklin
| Benjamin Franklin wrote [http://www.webexhibits.org/daylightsaving/franklin3.html a letter to the Journal of Paris in 1784] in which he advised them to rise with the sun in order to save candlelight, after he observed that the Parisians were getting up at the same time by the clock and burning a lot of candles in the winter as a result.
An "arbitrary decision by Benjamin Franklin" also likely refers humorously to Franklin having defined positive charge to be that which is left on a glass rod by rubbing it with silk. As described in [[567: Urgent Mission]], this had the unfortunate consequence of assigning a negative value to the charge of the electron, which was later identified as the fundamental carrier of electric charge.
| Benjamin Franklin is often touted as "the father of daylight saving time", despite him never actually proposing to alter the clocks.
|-
| an arbitrary decision by Isaac Newton
| Possibly a reference to how Newton divided the colour spectrum into the now-familiar seven colours of the rainbow, on a somewhat arbitrary basis. Newton did spend time working on the problem of calendar reform, but it's unlikely that any decisions he made as a result would affect anything, since he never published his work, and by the time it gained attention the Gregorian Calendar had been widely adopted.
| The spectrum fact is one of those standard bits of trivia of the kind the chart alludes to. Although it has nothing to do with time-keeping, Newton is the sort of person who seems like he should have made decisions like this.
|-
| an arbitrary decision by FDR
| Franklin Delano Roosevelt set all time zones one hour ahead year-round during World War II. The law was repealed after the war ended.
Additionally, he changed the date of Thanksgiving from the last Thursday in November to the fourth Thursday in November as a way to increase the length of the Christmas shopping season in some years.
| Setting the time permanently one hour ahead would make everything happen at the "wrong" time celestially.
|-
! colspan="3" | Related 'fact'
|-
| It causes a predictable increase in car accidents.
| colspan="2" | The week following daylight saving time, car accidents increase by about 5-7%<ref>http://www.cbc.ca/news/canada/end-of-daylight-saving-time-2015-6-eye-opening-facts-1.3296353</ref>.
|-
| That's why we have leap seconds.
| colspan="2" | Leap seconds occur because the time required for one rotation of the Earth is actually slightly longer than the 86,400 seconds in a standard UTC day. The Earth's rotation is slowing down by about 2 × 10-5 seconds every year due to tidal friction caused by the Moon's gravity; however, this is not one of the possible entries in the list of phenomena.

|-
| it was even more extreme during the [Bronze Age/Ice Age/Cretaceous/1990s].
| This may be reference to debates over climate change, where global temperature changes during these periods are frequently cited as supposedly proving / disproving human-related change.
| Solar events, such as sunspot activity, are often invoked as explaining temperature change in these debates. However, while there are a number of potential sun-related 'facts' that could be generated, none touch on sunspots.
|-
| There's a proposal to fix it, but it [will never happen/actually makes things worse/is stalled in Congress/might be unconstitutional].
| colspan="2" | Time zone reform is surprisingly a very controversial and politicized issue, with special interests on either side looking to modify it to fit their needs. Examples of proposals to modify the scheme include:

1550: Episode VII

2018-01-11T02:07:31Z

172.68.54.22: There is no reason to put "those" in bold. That word wouldn't even be stressed in the sentence, and isn't significant in the context. It's a minor English grammatical phrase. If anything should be emphasized (it shouldn't), it'd be "Power convertors"

{{comic
| number = 1550
| date = July 13, 2015
| title = Episode VII
| image = episode_vii.png
| titletext = The Lord of the Rings sequel, set years after the Ring hubbub has died down, is just Samwise discreetly creeping back to Bag End to finish dropping the eaves.
}}

==Explanation==
Sequels are often made to resolve pressing issues that are left unresolved in the original works. This comic was a humorous take on how the then-upcoming sequel in the {{w|Star Wars franchise}} might have resolved issues from a previous film in that series.

===Star Wars background===
In the first-produced movie of the series, ''{{w|Star Wars (film)|Star Wars:Episode IV: A New Hope}}'', {{w|Luke Skywalker}}'s uncle tells him to clean two newly purchased droids ({{w|R2-D2}} and {{w|C-3PO}}). Luke complains that he had plans to pick up some power converters at Tosche Station. Luke is told to clean the droids first; however, while doing so, he discovers a message carried by R2-D2, starting him on a course of events that runs through the original trilogy. As a result, he never ultimately goes to Tosche Station.

The conversation between Luke and his uncle, {{w|Owen Lars}}, is as follows:
:'''Uncle Owen:''' Luke! Take these two over to the garage will ya? I want ’em cleaned up before dinner.
:'''Luke:''' But I was going into Tosche Station to pick up some power converters!
:'''Uncle Owen:''' You can waste time with your friends when your chores are done. Now, come on. Get to it.

Luke's line is one of many well-known lines from the series and is often-quoted as an example of how Luke is initially portrayed as a whiny teenager. By the end of the {{W|Return of the Jedi|''Episode VI:Return of the Jedi''}}, Luke has grown into a mature and powerful Jedi, completing his transformation through the original trilogy.

====The Force Awakens====
''{{w|Star Wars: The Force Awakens|Star Wars Episode VII: The Force Awakens}}'' was, at the time of the comic's release, the upcoming seventh feature-length live-action film in the ''Star Wars'' series, and was the first since the rights to the franchise were sold by creator George Lucas to the Disney Company. It is a sequel to the original trilogy.

Since creating the original trilogy, many of Lucas's decisions in respect of the franchise have been subject to fan criticism, including criticism of the quality of three prequel films Lucas produced beginning in 1999 (after a more than 15-year hiatus). The new seventh film was entrusted by Disney to producer/director J.J. Abrams, who in 2009 produced and directed the highly acclaimed (although still highly criticized by some fans) ''Star Trek'' reboot.

Given all of this context, the new ''Star Wars'' film was as highly anticipated, or more highly anticipated than the prequel trilogy, and had a strong buzz around it. Much of the early buzz surrounded the nature of the new film's plot: For example, whether it would be a prequel or a sequel, and whether it would feature any of the original cast/characters

{{w|J. J. Abrams}} and others involved in the filming ''{{w|Star Wars: The Force Awakens|Star Wars Episode VII: The Force Awakens}}'' had appeared in a panel at San Diego Comic-Con the weekend prior to the comic's release to unveil details about the film. This is likely the impetus for the timing of this comic.

===The Comic===
This comic portrays Randall's own conception of what the sequel might have been. In his version of the movie, Luke returns home to {{w|Tatooine}} years later with R2-D2 to finish the errand that was interrupted. Luke goes to Tosche Station and says "I'm here for those power converters", thus completing this unresolved task from the first movie. The action is bookended by the opening and {{w|closing credits}}, suggesting this uneventful scene comprises the entire film.

Therefore, the comic jokingly implies that getting the power converters was the most pressing of all the unresolved issues in the other films, and the most interesting upon which to base the sequel. In reality, this would likely be one of the least entertaining and most disappointing sequels that could possibly be made (perhaps second only to a version that had no reference to the previous films at all).

Randall may have also been commenting that there are few if any unresolved issues in the Star Wars franchise that required revisiting and that the series should be left alone. Or he could have been making a joke about how sequels call back to elements of previous movies without fully considering the context. In this case, the farm he's buying those power converters for was destroyed more than thirty years ago.

The title text alludes to another fantasy franchise, ''{{w|Lord of the Rings}}'', and how {{w|Samwise Gamgee}} was similarly interrupted from a menial task of gardening and listening in on conversations outside {{w|Bag End}} by {{w|Gandalf}} and his quest to save the world at the start of the first film. The title text uses the term “dropping eaves” as Samwise did in his denial of eavesdropping in on the conversation between Frodo and Gandalf. In both cases, the issue of collecting power converters and Sam’s gardening duties were left unresolved in their respective stories and the main plot of the series is thoroughly concluded.

Talk:1535: Words for Pets

2018-01-07T06:52:53Z

172.68.54.22:

I skipped the first step by naming my cat "Cat". On the plus side, even in the third year I was still mostly calling her by her name. --[[Special:Contributions/108.162.254.134|108.162.254.134]] 08:06, 8 June 2015 (UTC)
:My cat is also named "Cat". Then again, I call all cats "Cat". [[Special:Contributions/108.162.210.138|108.162.210.138]] 19:00, 8 June 2015 (UTC)

Not sure this is relevant enough to include, but there's [http://tvtropes.org/pmwiki/pmwiki.php/Main/ADogNamedDog a trope about that] [[Special:Contributions/188.114.111.224|188.114.111.224]] 11:39, 8 June 2015 (UTC)

I interpreted this slightly differently. In the first year, the pet is fresh and new, and you put the effort in to call it by its name. As time goes on, you get sloppier about it. In addition, I believe he missed a ring from it: Expletives. Within a year of having a new cat, I was calling it more by expletives than its name. [[User:Drmouse|Drmouse]] ([[User talk:Drmouse|talk]]) 14:24, 8 June 2015 (UTC)
:I thought expletives were deliberately implied, so I'm very surprised they are not mentioned in the explanation. [[Special:Contributions/198.41.239.231|198.41.239.231]] 23:50, 8 June 2015 (UTC)

I disagree with the explanation. The comic is about words used to refer to the pet, i.e. to name the pet when talking to someone else, not to talk to the pet. For instance "I forgot to feed Lassie" might later become "I forgot to feed the dog", then "I forgot to feed the damn thing" or whatever. Am I the only one to understand "refer" like this?
Zetfr 16:53, 8 June 2015 (UTC)
:In my household at least, we use the animal's species as its name. For example, instead of "Have you fed Lassie?", we may say " Have you fed Dog?". I think is what Randall is implying. [[Special:Contributions/141.101.98.29|141.101.98.29]] 17:00, 8 June 2015 (UTC)
::Since he begins to refer to the animal in the animals language, I would say that only makes sense if he talks to the animal. However the way the caption is phrased it could be understood the way he talks about the animal. So I think it is impossible to say that one explanation is correct and the other is wrong. Maybe that should be mentioned in explain. --[[User:Kynde|Kynde]] ([[User talk:Kynde|talk]]) 18:14, 8 June 2015 (UTC)

:::Agreed. [[Special:Contributions/188.114.97.151|188.114.97.151]] 23:24, 28 December 2015 (UTC)

I got a completely different idea to this, the relationship is one of friendship, not parentage, so the moving from name to associated to other words to sounds would be more like Hey Lassie -> Hey Dog -> Hey Fatso -> Ugh, Oi. This shows more the common friendship trope of insulting one another in a humorous way, which seems far more likely than transitioning into some kind of hybrid language for all bar the most "maternal" of owners. [[User:Hackerjack|Hackerjack]] ([[User talk:Hackerjack|talk]]) 22:40, 8 June 2015 (UTC)
:I agree here. With our cat it was Hi Blaser -> Hi Cat -> You little **** -> Oi, you -> "Maw?" [[User:Drmouse|Drmouse]] ([[User talk:Drmouse|talk]]) 09:08, 9 June 2015 (UTC)

The "You little ****" is something I can definitely attest to. A friend of mine keeps calling his cats assholes and similar words, so often that I have a hard time remembering their actual names. "come here" isn't how one "refers to" a pet, it's how one might call a pet, which isn't what the comic is about at all... [[User:Maplestrip|Maplestrip]] ([[User talk:Maplestrip|talk]]) 09:15, 9 June 2015 (UTC)

:I call my dog "plague" (makes more sense in our dialect of Portuguese). [[Special:Contributions/188.114.97.151|188.114.97.151]] 23:24, 28 December 2015 (UTC)

I wouldn't say Randall is restricting this comic to either of the two major possibilities: speaking to the pet, or speaking about the pet. It could well be a mixture of both.
We have a cat whose name is "Pwca" (Welsh spelling, same as "Pooka" as in the Jimmy Stewart movie "Harvey") but the name varies between "Pwca" and "Picklebean" and just "Bean" right along with "silly kitty" and "funny girl" and other descriptive words. She has a typical little short chirp that she uses to get our attention or to complain about something, and we often chirp back to her, so that would be "the pet's own language." My daughter's cat "Minnie" is "Minners" or "Minimum" or "Min-Min" or again, descriptive terms. You could certainly argue that some of those words are borderline incoherent. In most cases, they can be used while speaking either /to/ the pet, or /of/ the pet to a third party (or sometimes to the universe at large.)
Note that the phrase "pet name" has a double meaning, with 'pet' either a noun or an adjective, and in the latter case usually not actually referring to a pet.[[User:Taibhse|Taibhse]] ([[User talk:Taibhse|talk]]) 00:43, 10 June 2015 (UTC)

Randall talks to cats: [http://xkcd.com/231/ 231] {{unsigned ip|108.162.219.83}}

I thought it is Vienn diagram not Euler diagram {{unsigned ip|108.162.254.47}}

I call my kitty "foofy butt," "foofbutt," "fluffbutt," "plushbutt," "puffbutt," "squishy," [gibberish cooing], "meow meow," "hairy baby" (BH6 is my favorite animated movie), identical meows to his, and sometimes, occasionally, his actual name Mitu. Or Mittu My mom spells it differently than me. For the longest time, autocorrect autocorrected his name to MIT. xD Now all I can picture is me stroking the dome of one of the best schools in the entire world like it's a kitty. KITTY.

I miss him. He has lung cancer, and is at home, and I'm away at college. My poor little foofehbutt :c

If you just listened to what my mother called her cats throughout the day you'd think their names were "Trouble" "You Ratbag" and "Get down off that!" -Pennpenn [[Special:Contributions/108.162.250.162|108.162.250.162]] 01:22, 15 January 2016 (UTC)

By the time my parents' dog died her name had expanded from 'Lucy' to 'Lucius Germanicus P. Codwagon the Great' and my dad would talk about how she got lost up in the frozen spruce country and saw the Wendigo. To be fair she was like 14 by that point, so it's possible that we had reached past talking to her in her language to achieve complete screaming psychosis. She seemed to enjoy being told spooky stories about herself, though, so that was okay. [[Special:Contributions/162.158.59.142|162.158.59.142]] 04:44, 7 August 2017 (UTC)

Maybe it's just me, but I interpreted it as referring to the gradual transition where the pets name is gradually morphed into something else and/or it's given a nickname, which also eventually morphs. I once had a cat named "Smoky", which became "Swiss Mocha", and eventually "Bin-Bin" (I forget how exactly". My dog "Rasta" eventually became "Googer" or "Biggur" (I think that was "Good girl" and "Big girl" originally; "Biggoogurl" was also used sometimes). "Pupplet" and "Dogalog" also saw use. Her actual name is reserved for when she is bad or I'm trying to get her attention when she's running around outside. [[Special:Contributions/172.68.54.22|172.68.54.22]] 06:52, 7 January 2018 (UTC)

1503: Squirrel Plan

2018-01-06T07:36:31Z

172.68.54.22: /* Explanation */

{{comic
| number = 1503
| date = March 25, 2015
| title = Squirrel Plan
| image = squirrel plan.png
| titletext = [Halfway to the Sun ...] Heyyyy ... what if this BALLOON is full of acorns?!
}}

==Explanation==
These particular squirrels are ambitious but misguided, like the characters in the myth of {{w|Icarus}} and {{w|Daedalus}}, or the {{w|Tower of Babel}}. The squirrels' understanding of astrophysics is lacking, regarding the distance to the sun and appropriate transportation to reach it in addition to the need to resist the sun's heat and exist in the vacuum of space. Their belief that the sun is made of acorns reflects their uniquely acorn-focused worldview, a reference to the tendency of real-life squirrels to gather and store acorns as winter food, as well as their relatively low intelligence.

The title text reveals that "halfway to the sun," 75 million kilometers from all known acorns in our universe, the airborne squirrel seems to jeopardize the entire mission because he wants to test if the balloon itself is full of acorns. Basic observational skills will tell anyone that acorns do not float, but the idea follows the logic stated by the squirrels: If the sun, being so magnificent, must be full of acorns, then a balloon powerful enough to take a squirrel to the sun must also be powered by something amazing, like acorns.

In the real world [http://www.thenakedscientists.com/forum/index.php?topic=1020.0 helium balloons cannot escape the stratosphere.] Perhaps the squirrel only ''thinks'' he's halfway to the sun. Or maybe the acorns in the balloon are pushing on the [[1404:_Quantum_Vacuum_Virtual_Plasma|quantum vacuum virtual plasma]].

The "shooting a hole in the balloon" is based on Larry Waters, who actually flew in a lawn chair suspended below a large cluster of helium balloons, using a pellet gun to shoot out balloons to descend. Featured in [[What If: Falling With Helium]].

==Transcript==
:[There are three squirrels. One is suspended from a balloon. The other two are sitting on the ground, looking up at it.]

:Squirrel to the right: Once you've chewed a hole in the sun, shoot the balloon to fall back to earth, then pull the parachute ripcord to land.

:Squirrel tied to balloon: Are you '''''sure''''' it's full of acorns?

:Squirrel to the right: Look how bright and magnificent it is! What ''else'' could be in there?
==Trivia==
It is commonly believed that real squirrels use their ''tails'' as parachutes, although as yet [http://io9.com/5946627/squirrel-hurls-itself-through-a-fourth-story-window-scampers-off-unscathed "there have been no observational studies on the aerodynamics of free-falling squirrels."]

233: A New CAPTCHA Approach

2018-01-06T06:05:48Z

172.68.54.22: /* Explanation */

{{comic
| number = 233
| date = March 9, 2007
| title = A New CAPTCHA Approach
| image = a new captcha approach.png
| titletext = They'd use that Futurama episode with Fry's dog, but even spambots cry at that.
}}

==Explanation==
A {{w|CAPTCHA}} is a verification system to stop automatic submissions to web forms by asking the user to do something a computer program could not do, such as type a distorted word into a box.

But here, the author has a new CAPTCHA, in which it references a sad event in the children's movie ({{w|The Land Before Time}}). It asks the subject if it felt sad. If the subject is human, then they most likely will have felt sad, so the answer will be "yes." If it's a computer program, however, it is supposed to answer "no," because computer programs cannot feel. This CAPTCHA would be extremely easy to break, however, because a computer could easily find the "yes" button and press it. However, the "trap" is that a computer program doesn't "know" that it's supposed to answer "yes", as it lacks human emotion and empathy. It is similar to the way that humans are very good at being shown simple drawings of an object or an action and being able to tell immediately what it is, while computers can't. The "no lying" instruction is ostensibly meant to patch that hole, but unfortunately, it turns out that spambots are not generally programmed with the Three Laws of Robotics.

The title text references the {{w|Futurama}} episode {{w|Jurassic Bark}}. It claims that this episode is so sad that even {{w|spambot}}s cry after seeing it.

You can't write formulas like that! °C is degree(s) Celsius, not the value of some temperature as measured in degrees Celsius. You should write something like [°C] or °C-1 instead (if we treat °C as an affine function mapping dimensionless values to temperatures).

1285: Third Way

2017-12-01T19:26:10Z

172.68.54.22: /* Explanation */

{{comic
| number = 1285
| date = November 1, 2013
| title = Third Way
| image = third way.png
| titletext = 'The monospaced-typewriter-font story is a COMPLETE FABRICATION!  WAKE UP, SHEEPLE' 'It doesn't matter! Studies support single spaces!' 'Those results weren't statistically significant!' 'Fine, you win. I'm using double spaces right now!' 'Are not!  We can all hear your stupid whitespace.'
}}

==Explanation==
This comic refers to the debate occurring in the United States about the correct {{w|Sentence spacing|number of space characters after the end of a sentence}}.

While text written on typewriters in the United States traditionally had two spaces between sentences, this is becoming less common and many sources now recommend having only one space, although this topic is still {{w|Sentence spacing#Controversy|controversial}}.

[[Cueball]] is advocating a line break after every sentence, the eponymous "third way", and sometimes called "[http://rhodesmill.org/brandon/2012/one-sentence-per-line/ semantic linefeeds]".

This is particularly useful when plain text files based on a markup language (such as HTML, TeX, or {{w|Wiki markup}}) are edited by multiple people using a {{w|Revision control|version control system}} where it helps to facilitate comparison of changes and avoid merge conflicts.

In most markup languages, a single linefeed in the source is rendered as a simple space, while two linefeeds generate a paragraph break.

This approach allows the source to be easily manipulated and versioned, while the rendered output still keeps the regular flow and justification abilities of running text.

The title text uses single spaces between the back-and-forth quotations; but within each quotation, the quoted speaker's preferred spacing is used.

In particular, when the single-spacing advocate claims to be using double spacing, this is indeed a lie.

However, realistically, it is implausible that one can hear whitespace{{Citation needed}}.

Sentence spacing was previously mentioned in the titletext of [[1070: Words for Small Sets]].

Note that this is not the first time Randall has [[:Category:Compromise|proposed a controversial third way]].

Randall's mocking characterization in the title text of overzealous advocates using the phrase "WAKE UP, SHEEPLE" has appeared in previous comics [[496: Secretary: Part 3]] and [[1013: Wake Up Sheeple]].

After the update to {{w|Apple Inc.|Apple's}} {{w|IOS_11#11.1|iOS 11.1}}, many (though not all) {{w|iPhone}} users suffered from a strange bug, where the {{w|autocorrection}} changed any input of the single lowercase letter "i" to either "A" or "!" followed by a space and a Unicode {{w|Variation Selectors (Unicode block)|variation selector 16}} (U+FE0F, on iOS displayed as a question mark in a square).<ref>http://www.loopinsight.com/2017/11/06/ios-bug-autocorrects-letter-i-to-a-plus-unicode-symbol-heres-a-workaround-and-a-clue-to-the-cause/?utm_source=loopinsight.com/twitter&utm_campaign=twitter&utm_medium=referral</ref> Using a {{w|Specials_(Unicode_block)#Replacement_character|replacement character}} to approximate this display, the result of typing "i took" might be "A � took" or "! � took". In a handwritten text, the "�" symbol could then be mistaken for a censored word. This problem also manifested as an "I" followed directly by the VS-16 "emojify character", turning them into an " �" without the "A".<ref>https://twitter.com/willkirkby/status/925865928193134593</ref>

The codes in the title text refer to "A �" and "! �" respectively. The text provides a way to keep the "bug" active, (which can be realized through the use of a Cydia tweak) even after it is patched. This is a fairly silly concept, as not many people would need to type "A �" more than they would need to type "i".{{Citation needed}}

The statement in the title text "no update can never take this away from you" is a {{w|Double negative|double negative}}, so it actually means "any update can take this away from you". This may be a typo.

[[Hairy]] is working at a tech support office, and receives a call from [[Cueball]]. After the scripted greeting, Cueball, who [[1084|has the]] [[1586|weirdest]] [[1700|tech issues]], tells Hairy that his thermostat - a single-purpose device used to adjust the settings of indoor heating - is showing an ''Android error screen'', and asking if he wants to partition the volume. The android error seems to imply that it is trying to mount a file with .doc extension (most likely a [[1459|Microsoft Word document]]) as the {{w|Boot_device|boot device}}. An added twist is the "(1)" in the filename, which is appended when a MS Word user attempts to copy a file into a directory that already has a file of that name. This is so abnormal that Hairy is briefly struck silent, and upon recovering, he suggests Cueball [[349|walk into the sea]] as a form of suicide.

1909: Digital Resource Lifespan

2017-11-03T07:20:17Z

172.68.54.22: /* Explanation */

{{comic
| number = 1909
| date = October 30, 2017
| title = Digital Resource Lifespan
| image = digital_resource_lifespan.png
| titletext = I spent a long time thinking about how to design a system for long-term organization and storage of subject-specific informational resources without needing ongoing work from the experts who created them, only to realized I'd just reinvented libraries.
}}

==Explanation==
{{incomplete|Can someone make a table of all the different resources types?}}

In this chart, [[Randall]] laments the tendency of digital resources to quickly become obsolete or non-functional. By taking a general subject, such as xkcd's core subjects of "romance, sarcasm, math, and language", one can see that a useful tool such as a smartphone or computer app or interactive CD-ROM (essentially, software) does not have the lasting power of printed books (e.g. textbooks, for many general subjects) and microfilm/microfiche. The printed resources, not having to rely on a computerized platform for use, are far more reliable despite being less mobile and taking up physical space. The only digital source which is still working is {{w|Portable Document Format}} (aka PDF) which encapsulates fixed layout flat documents, and is supported for years already by {{w|Adobe Systems}} and is part of {{w|International Organization for Standardization|ISO}} standards, so has a widespread support, and should be still viewable in foreseeable future.

The title text makes a statement that libraries do not require the support of ''original'' authors/experts to organize and store vast resources for any subject imaginable. This is true, but omits the fact that ongoing efforts are required by experts in information organization and storage -- namely, librarians. Physical books and microfilm/microfiche need controlled storage environments, manual handling for storage, retrieval, distribution (in library terms, "circulation"), and the like. Thus, a library can require significant resources in personnel and facilities, but is usually seen as a "public good" for the benefit of society; thus, many communities and educational institutions invest in creating and maintaining a library despite the costs.

Archive.org refers to {{w|The Internet Archive}}, a non-profit organization that maintains the {{w|Wayback Machine}}, one of the largest archives of the {{w|World Wide Web}}. When a website is taken offline, copies of its content can often be found backed-up on the Wayback Machine. The Wayback Machine is primarily designed to back up {{w|Website|websites}}, however, and will often not be able to save information stored in a site's {{w|Database|databases}}, as alluded to in the comic. The Internet Archive has a part for non-website archives, but it cannot hold recent databases either due to copyright problems.

1889: xkcd Phone 6

2017-09-13T20:43:49Z

172.68.54.22: /* List of features (clockwise from center/top) */

{{comic

}}

==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 iPhone X 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{{Citation needed}}.

; 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{{Citation needed}}. 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).

; 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 make a call with beards. 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{{Citation needed}} - 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

:Wireless charging has no wires, and 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. A operating system distributes the CPU's time over all active threads. CPU's don't generally have a limit on the number of threads (some operating systems do), however with a certain number the amount of cycles per thread becomes too low to be of much practical use. This seems to be a joke about bedding, where high thread count is actually a reasonably advertizable statistic.

; Shroud of Turin-style facial transfer unlock

:The {{w|Shroud of Turin}} is claimed to display an image of the face of {{w|Jesus Christ}}, appearing as if it was transferred to the cloth. Presumably, to unlock this phone, the user must press their face against it.

; Fonts developed by NASA

: NASA's expertise is not in fonts{{Citation needed}}, and the fonts on almost all modern phones are the same.

; Includes applicator

: What tampon packages often say.

; Burns clean coal

: There is a push for clean energy production as a result of increased awareness of global warming. While it may be useful for a phone to be able to produce its own energy, coal is by definition not a clean energy source because it produces carbon dioxide. The phone is not stated to have a vent for the CO2 to escape, which would technically make the coal "clean" as it is not entering the atmosphere. However, the gas is instead trapped inside the phone, which will quickly ruin it through a combination of heat and pressure.

; 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.

; 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 phosphorescent element radium sparked a brief fad in which some watch makers painted watch faces or hands with the substance so the time could be read at night. 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 phosphorescence of radium 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}} is a phablet announced together with the iPhone 8 by Apple on September 12, 2017, a day before this comic was released
*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.

1871: Bun Alert

2017-08-03T13:39:24Z

172.68.54.22: /* Explanation */

{{comic
| number = 1871
| date = August 2, 2017
| title = Bun Alert
| image = bun_alert.png
| titletext = Since buns range from crepuscular to nocturnal, it's recommended that you enable the scheduled "Do Not Disturb" mode on your phone to avoid being woken by alerts about Night Buns.
}}

==Explanation==
{{incomplete|Still needs work.}}
The comic opens with [[Beret Guy]] identifying a "bun", the name given to a {{w|rabbit}} in [[1682: Bun]].

Upon seeing the bunny, Beret Guy uses his phone to send an alert about the "Bun" with a [[wikipedia:Push technology|push notification]]. He is still looking for investors, though, such an app would likely not appeal to a wide market. In response to [[Ponytail]]'s confusion, he explains states that bunnies are "like loaves of bread that hop" perhaps making a pun by comparing rabbits to bread, as "bun" can commonly refer to a small loaf of bread.

As Ponytail leaves, apparently to remove herself from the situation, [[Megan]] hurriedly approaches, excited to see the bun. This serves as a punchline as despite Ponytail appearing to be the voice of reason, it seems that Beret Guy's inane bun alert system has gathered a dedicated following after all.

The title text refers to buns being {{w|crepuscular}} and {{w|nocturnal}} animals, meaning they are primarily active at twilight and night, respectively. This means that someone with the app would get a lot of notifications while they would most likely be asleep.

Megan's question "Is it small?" and her amazement when she find out that it is parallels the idea in [[1682: Bun]] where the bun's size is said to be inversely correlated with its status; smaller buns such as the one in this comic are thought of as higher-ranking "king buns" by the characters in both strips. In real life, smaller rabbits are more likely to simply be children.

==Trivia==
*In [[1682: Bun]], it was Ponytail who was infatuated with "buns", while Megan was the incredulous one questioning the situation. In this comic, the roles are reversed. This is a strong indication that the characters represented by Ponytail and Megan in this comic are not the same characters from 1682.

:[Beret Guy and Ponytail see a rabbit sitting in the grass; Beret Guy points to the bun.]
:Beret Guy: Bun alert!
:Ponytail: Oh, yeah! Cute!
:Beret Guy: Gotta document this. I'll notify everyone, send out a push alert.
:Ponytail: ...to who?

:[Zoom in on Beret Guy and Ponytail; Beret Guy taps on his phone.]
:Beret Guy: Everyone subscribed to the alert system.
:Ponytail: Alert system?
:Beret Guy: Yeah! We built it over the last few years. It's pretty small. Still looking for investors.
:Ponytail: But...''why'' are you alerting people about rabbits?

:[Zoom out; Beret Guy points at the bun.]
:Beret Guy: I mean...look at them. They're like loaves of bread that hop.
:Ponytail: I see.
:Beret Guy: ''People need to know.''

:[Zoom on Beret Guy in a frameless panel.]
:Beret Guy: They need to know:
:Beret Guy: '''''There are buns.'''''

:[Ponytail walks off, Megan comes running towards Beret Guy with a phone in her hand.]
:Ponytail: Okay, uhh, I'm gonna go.
:Megan: ''I got the alert!'' Where's the bun? '''''Is it small?'''''
:Beret Guy: ''Extremely.''
:Megan: Oh my God.

Talk:1870: Emoji Movie Reviews

2017-08-01T14:43:46Z

172.68.54.22:

There are many ways that a movie can be bad. It could have uninteresting characters, a bad plot, stupid dialogue, poor filming etc. Very likely the Emoji movie suffers from all of these problems. I should add that Jar Jar Binks from Star Wars fame was widely hated by anyone over 8 years old but my 5-year-old loved him. Could the same thing be true for Emojis? [[User:Rtanenbaum|Rtanenbaum]] ([[User talk:Rtanenbaum|talk]]) 18:00, 31 July 2017 (UTC)
:So, similar to the minions movie series? 20:00, 31 July 2017 (UTC)[[Special:Contributions/141.101.104.125|141.101.104.125]]
::The minions and the "prequel" (I don't know the english title) are not only watched and enjoyed by children - at least in Germany - but also by young adults. [[Special:Contributions/198.41.242.5|198.41.242.5]]
:::I can see how happy pills would be popular among the Germanic depressives. :P [[Special:Contributions/162.158.75.100|162.158.75.100]] 20:37, 31 July 2017 (UTC)

:::Of the Star Wars prequels, the one which had the most of Jar Jar Binks was the first one, whose English name was Star Wars Episode I: The Phantom Menace. And you should note that Rtanenbaum wasn't talking about the whole movie, but specifically the character of Jar Jar Binks (the clutz alien with long floppy ears). Plus, I think most adults (or "anyone over 8 years old") hated him for how he spoke, so other language adaptations might have made him better, LOL! [[User:NiceGuy1|NiceGuy1]] ([[User talk:NiceGuy1|talk]]) 04:03, 1 August 2017 (UTC)
:::: Well, at least not in Germany XD [[User:Elektrizikekswerk|Elektrizikekswerk]] ([[User talk:Elektrizikekswerk|talk]]) 06:24, 1 August 2017 (UTC)

Sorry, does anyone genuinely believe that the writers would not actually know about the eggplant? Out of dozens, nay hundreds of useless icons, this one would have been unconsciously selected by random chance? {{unsigned ip|162.158.2.160}}
:Cueball even asks, "was that on purpose?".

Possible title text explanation: The idea doesn't survive in the real world because (A) people typically don't express emotion by turning their head upside down, and (B) it's rare that you run into a person who is thinking (a very jaded, cynical view of humanity popular among internet users).

1302: Year in Review

2017-06-07T01:39:40Z

172.68.54.22: /* Explanation */

{{comic
| number = 1302
| date = December 11, 2013
| title = Year in Review
| image = year_in_review.png
| titletext = All in all, I give this year a C-. There were no aurora visible from my house and that comet evaporated. They'd better not cancel the 2017 eclipse.
}}

==Explanation==
Many news organizations will recap the major stories of the past calendar year in late December (typically before the year has actually ended). This includes specialized news outlets such as sports stations which recap major sports stories or best plays of the year. Here, [[Cueball]], as a [[:Category:News anchor|news anchor]], expects [[Megan]] to talk about major news stories of 2013 such as the roll-out of {{w|Obamacare}}, the {{w|Papal conclave, 2013|election}} of {{w|Pope Francis}} or the {{w|Death of Nelson Mandela|death}} of {{w|Nelson Mandela}}, to give a few examples.

Instead, Megan only recaps one thing which was important to her: She did not see the {{w|aurora borealis}} (i.e. northern lights) in 2013, the dazzling natural geomagnetic light display caused by the {{w|solar wind}}. In 2013 a solar maximum was expected at its {{w|solar cycle}}, but the activity of the sun wasn't as heavy as before. So, a ''northern light'' had been very rare in this year. Megan has never seen the northern lights, and she is frustrated that it did not happen for her in 2013, thus overshadowing all other events. She even leaves in the middle of the review when she notices the sky clearing up, as she wishes to check if there are any northern light this evening. This may very well be [[Randall|Randall's]] own frustration which is displayed here.

It turns out in the title text that Megan is actually reviewing the astronomical year, only considering astronomical events. She even rates it much like a movie review, although she seems to use the {{w|Academic grading in the United States|A-F grade scale}}. She only gives the year a C- (C minus), which would usually be the lowest passable grade, so she just lets the year pass in spite of the two failing events mentioned in the title text.

In the title text, Megan specifically complains about not being able to see aurorae from her house. If Megan actually represents Randall's frustration, then to expect to see it from a house in Massachusetts would be a lot to ask for. Usually, people who wish to see Northern lights will travel to an arctic area and stay away from light pollution from cities. But in years with heavy solar activity, northern light may be visible even south of Massachusetts.

The title text also refers to {{w|Comet ISON}}. In February, a rough estimate of the comet's behavior predicted that it would become brighter than the full moon, a prediction that was widely reported by the media even though it was based on limited data and astronomers knew that it would not reach this brightness. In the end, although it was visible to the naked eye, it was never as bright as anybody hoped and apparently disintegrated on November 28, 2013, at its close approach to the sun.

The title text also refers to the {{w|2017 total eclipse}}, which will be visible as a partial eclipse for a few hours throughout North America on August 21 Monday, including a 100-mile band across the United States where it will be a total {{w|eclipse}} for a couple of minutes in the early afternoon. Although the weather may be cloudy so the sun will be blocked during totality, the eclipse will happen anyway as there are completely predictable. So Megan is being extremely pessimistic to even suggest that it might get canceled. That she also states it like someone might decide to cancel the eclipse like it was a concert that could be canceled by the organizer is funny. Seems like Megan thinks "they" are the same that caused the comet to disintegrate and the solar activity to stay low. Anyone with the kind of power to stop a solar eclipse from happening would be God-like compared to humanity.

All in all, the comic suggests that the only events of significance to Megan (and Randall) are astronomical ones; the actions of humanity pale in comparison.

The joke of Megan answering a question in an interview in an unexpected manner has been used before in [[1111: Premiere]].

Interestingly in [[1037: Umwelt]] there is an [[1037#Aurora|aurora story line]] where Megan stays inside at her computer even though it can be seen from her own state, letting her friend go out alone. (So not the same Megan for sure).

1302: Year in Review

1846: Drone Problems

2017-06-07T01:05:20Z

172.68.54.22: /* Explanation */

{{comic
| number = 1846
| date = June 5, 2017
| title = Drone Problems
| image = drone_problems.png
| titletext = On the other hand, as far as they know, my system is working perfectly.
}}

==Explanation==
{{incomplete|Possibly more, may contain language errors.}}

[[Megan]] is frustrated because of people flying {{w|Unmanned aerial vehicle|drones}} too close to her, so she builds a system to shoot them down and shows it to [[Cueball]], who clearly is also excited about the idea and helps spot the drones. However, each of the drones gets accidentally destroyed by its own pilot because of their inability to fly the drones.

After three hours of unsuccessful drone hunting, a frustrated Megan complains about people unable to fly the drones, which prevents her (and Cueball) from having fun shooting them down. The joke is that she originally created the system to get rid of the drones, so the lack of drones should be the desired output - and now she wants the drones nearby (even if only temporarily).

This comic is a follow up on [[1842: Anti-Drone Eagles]], and confirms that Cueball prefers technological air-defense systems to biological measures, .

The title text refers to the fact that from an outsider's perspective, the system is keeping all the drones away from the house.

Another possible secondary joke is that the drones were flying near her because the pilots can't fly properly.

Megan had previously suggested, in [[1586: Keyboard Problems]], that robots (and thus also drones) getting near Cueball's house ({{tvtropes|TheJinx|and possibly Cueball's general vicinity}}) would unexpectedly crash.

Megan previously had a laser canon to shoot down squirrels in [[382: Trebuchet]], so this is not the first time she has build a device for shooting annoying things down...

==Transcript==
:[Megan is sitting on her knees at the porch in front of a house with a smartphone in one hand and operating with her other hand a dish-antenna pointing into the sky. Cueball comes walking up towards the stairs up to the porch while he is looking back and up over his shoulder and pointing into the air.]
:Megan: People in the park keep flying drones near me, so I've built a system to shoot them down.
:Cueball: Cool! Oh yeah, there's one now.
:Megan: Time for a test!

:[Zoom in on Megan with the device on the porch with Cueball still at the bottom of the stairs leading down. She is operating her phone, which can be seen to be connected with a wire to the dish-antenna device. Cueball is looking away from her and down.]
:Megan: Okay, locking on…
:Cueball: Wait, it just crashed.
:Megan: Damn.

:[Cueball has walked up the stairs and are standing behind Megan at the door. Megan is now looking up into the sky while still sitting with her phone in front of the device.]
:Cueball: Here comes another one! Aim for… nope, it got stuck in a tree.

:[Cueball is now sitting on the porch with a half full drinking glass in one hand leaning back on the other hand. Megan is gesturing at her device while holding her phone down. Above the top part of the frame there is another smaller frame overlaid with a caption:]
:Three hours later…
:Cueball: Finally, two more just— no, one crashed and the other is hurtling sideways toward the lake.
:Megan: ''Will you people learn to fly these things?!''
