:Okay, followup: it behaves quite differently on the non mobile site. You get two entry points with red balls and yellow balls and you need to place the various gizmos to direct the balls to the correct exit point. Once enough have correctly passed to turn the red X into a green tick, you have the option to submit. If you do, once you have named your design it will be added to the grid with other submissions all of which exist to push red and yellow balls around.

On the "machine" section, you see lots of "under construction cells". Perhaps this will develop as more are submitted.

Had quite a lot of fun, added a few 'successful' machines to the grid. Noted that whenever I try to use the Prism that (after a short delay) the comic-pane blanks and I need to refresh the page/get a completely new 'challenge' to start from scratch, so I'm just not using the prism at all (used most of the other items, in combination or 'just the one across the whole board', whichever seems most fun). But it doesn't seem to do what I'd like it to do, which is sort multiple colours from the same inflow into different outflow directions. Which would be ''very'' useful in a 'crossroads' situation, the general solution of directing them cross-path being too prone to random collisions. Also might be useful in the 'submitted machine grid', as I note that errors propagate, whereas adding a filter on all inputs would clean out (dispose of/send off to a valid gate?) the rogue balls. Anyway, gonna have to come back to this later when there's more time... Maybe then I'll even have something useful to add to the Explanation. [[Special:Contributions/172.70.163.31|172.70.163.31]] 19:03, 6 April 2024 (UTC)

The balls appear to be different weights. I just saw a machine that used fans to separate yellows from greens and blues in a sort of 'wheat from the chaff' manner to direct them to their correct outputs. I wonder what other hidden tricks are included. [[Special:Contributions/172.68.1.159|172.68.1.159]] 19:40, 6 April 2024 (UTC)

They're not all accepted, though it makes you think they are. Or something else more complex is going on we haven't realized yet. I made a machine that was working reliably, submitted it, and saw it on the overall grid. Reloading from a different browser I found the same location of the machine, with the same surroundings, but my machine had been replaced. It's nowhere else on the grid either. The first browser still shows it (but not after a reload with a cache clear). I'm not sure if there's some kind of "save" event that needs to happen beyond seeing your machine in the broader one, or if all user collaboration is an illusion, or if the system changes its mind about us somehow.

: Yeah, i've been seeing this too. Please tell me if you find any of my machines, images at https://i.hypercone.us/?v=22d562 , https://i.hypercone.us/?v=ad8e3a , and https://i.hypercone.us/?v=8d4d6a . I want to be one of the few to have added Catalan and Spanish to the grid. [[Special:Contributions/172.71.134.164|172.71.134.164]] 20:56, 6 April 2024 (UTC)

I've added some more observations to the page. Also, a guess which is too uncertain to put on the main page: The ball launcher for the yellows on the far left side misses a lot, and the yellow container isn't the one on the left. So I think the whole machine with crossing streams will result in the colors being sorted in their container order, and possibly have the streams combined and deposited at the bottom just above the containers. --[[Special:Contributions/172.71.147.100|172.71.147.100]] 21:07, 6 April 2024 (UTC)

trying to see it on Firefox for Ubuntu and it just tells me to "visit xkcd.com to view" - THAT'S WHERE I AM?! Tried clearing website data (but not my entire cache) and that didn't help. Is there something I'm missing?

Oooh, just had one with four ball-entries (four colours) and ''three'' exits (one caters for two arrows). Pity it's rather complicated to get entries to exits (even if I can merge two of the streams). Might have to give up on it, but I'd like to have seen how it fits in with the 'submited grid'. i.e. someone else gets a two-colour introduction spot.

:Me again. I'm just refreshing the page, looking at the pattern of entries/exits (just a dozen or so screens in, getting some repeats of pattern, indicating that it's going back to tiles it was suggesting before, probably depends on how many others are contributing and extending...)
:Found another 'double-colour' example. Two yellows ''from the same side'', which probably means that there's a two-yellows been asked to exit from the neighbour (will check shortly).
:Quickly adapting from my spreadsheet notation, "R, Y, G, B" in order, each "(Entry, Exit)", I've been using <dir> of L/R/T/B and a number (nominally percentage, though seems to include only values of 20, 30, 50, 70 and 80, so it ''might'' be more 1/6..5/6?) relating to the distance along from L to R (for T/B) or T to B (for L/R).
:This line is therefore (0,0)(L20+L70,R30+B70)(R80,L80)(T70,L50) ... no reds, two yellow pairings, a red pairing, a blue pairing. Would require at least two path-crossings (but I was going to calculate those things later, and double-colours might confuse my intended simple line-intersection calculation).
:...anyway, spent some time on this message, which might mean I'll get into a 'new batch' of available patterns as people have succeeded some of the challenges that I've been 'swiping left'. [[Special:Contributions/172.70.162.20|172.70.162.20]] 19:28, 7 April 2024 (UTC)

:Ok, stopped my refreshing to [https://imgur.com/a/OMFOmzy 'solve' a screen]. First of all I routed both yellows entries (right-upper and upper-right) to one yellow exit (middle-left) and gradually teased the greens across (lower-left to middle-right), as that way I was avoiding a criss-cross of balls, but the the other yellow exit (left-lower) was, of course, invalid.
:Changed it to drop one stream of yellows down towards the lower exit, across the rapidly firing greens (added a fan to filter away the occasional yellow that gets bounced over there, not much of an opportunity to filter falling-greens out of the yellow exit, so apologies to whoever gets the sceen below). Submited as "Two Yellows, One Green!", whether or not that'll save (apparently, I should continue to contribute and not refresh/close, or else the server will not keep the solution?).
:Interestingly, all four adjacent tiles are "Under construction", and if I scroll up... *DARN* the comic has blanked out (nothing there between the upper PREV/RANDOM/NEXT buttons and the lower ones, just whitespace). This may mean that it did not save. This is the kind of 'page crash' I get when I try using a Prism or get too many balls rattling around on top of a Black Hole. Perhaps it doesn't like that I'm scrolling into an Under Construction that shouldn't be there? (But then, why ''is'' it there?)
:Anyway, all extra information for everyone.
:I'll just refresh the page and go back and do some more entry/exit mapping, maybe? [[Special:Contributions/172.70.162.20|172.70.162.20]] 20:17, 7 April 2024 (UTC)

If you combine a bunch of these silly claw things in the middle by just spamming it, it begins to lag and do some chaotic collisions, even without balls colliding on it. It's curious how it does that seemingly randomly though. I wonder how calculations are added and if there's a tiny sprinkle of RNG. (Also, errors occur and say something about damaging recursion in the Rust programming language, so I guess we know how it was made. It's also pretty weird how there's not a lot of opening combinations? It's possible that the machine loops over in chunks of gears or something (that's what I'll call them). ([[User talk:Leo|talk]]) 13:15, 7 April 2024 (UTC)

If you place a black hole in the centre of a wheel, it makes the wheel behave unpredictably between resets. Sometimes it's almost normal, sometimes it's a lot faster than usual, and sometimes it's stopped but launches balls that touch it with extreme force. I was able to use this to submit a machine which didn't actually let a single ball through after being submitted. https://i.hypercone.us/?v=928bcd [[Special:Contributions/162.158.33.149|162.158.33.149]] 01:19, 7 April 2024 (UTC)

The page says that (and I have taken note of) the ball hue is ''coded'' to certain values, but is there a logic to those values that might be derived from the colour (either as RGB triplet or HSV/other colourspace definition). For example, the two ball-types with zero green component in their makeup are 'unit density' (green is far heavier "green+red" is far lighter, so it's not a simple relationship, unless it converts from °hue, in some way) and the only secondary colour exhibits non-zero drag. There's the possibility that it just derived from "we need different properties, we need different colours, we have no reason to connect either with other deliberately" or even some non-mathematical symbology (fire=red, water=blue(?), earth=green, air(/sunlight?)=yellow). But it makes me wonder what combination of properties cyan/magenta balls might have, if added. (Or is the choice of those four colours constrained, anyway? Though R/G colorblindness is already something of an accessibility failure, if anyone suffers that.) [[Special:Contributions/172.69.194.205|172.69.194.205]] 17:02, 7 April 2024 (UTC)

2899: Goodhart's Law

2024-02-27T14:03:57Z

141.101.99.101: /* Explanation */

{{comic
| number = 2899
| date = February 26, 2024
| title = Goodhart's Law
| image = goodharts_law_2x.png
| imagesize = 295x321px
| noexpand = true
| titletext = [later] I'm pleased to report we're now identifying and replacing hundreds of outdated metrics per hour.
}}

==Explanation==
{{incomplete|Created by a METRIC OF METRICS PER METRIC METRIC (IN <s>IMPERIAL</s> US CUSTOMARY UNITS) - Please change this comment when editing this page. Do NOT delete this tag too soon.}}

In this comic, [[White Hat]] suggests creating a metric, "number-of-metrics-that-have-become-targets," and making it a target.

First, the comic introduces and defines {{w|Goodhart's Law}}, which is the observation that when a metric — a {{w|performance indicator|measure of performance}} — becomes a goal, efforts will be unhelpfully directed to improving that ''metric'' at the expense of systemic objectives.

For example, imagine a scenario in which a car dealership is looking to grow profits, and its managers decide to focus on increasing a component metric of profit: how many cars it sells. So they offer a bonus to their salespeople to sell more cars. But then the salespeople offer deep discounts to rack up sales, rendering the car sales unprofitable. This example shows how a ''metric'' (cars sold) can become the ''target'', replacing the real target, profit growth, if individual incentives are not properly managed.

White Hat's suggestion could be a good or a bad idea. It all depends on how the incentive is implemented:

* A '''good implementation''' would award bonuses only for finding metrics which truly aren't serving their purpose, so the organization's managers could fix the measurement issues. If bonuses are awarded only for approved submissions and the identifications result in real improvements, the organization will benefit from each misaligned incentive that is removed.

* A '''bad implementation''' would offer a bonus to every identification — regardless of quality. This would incentivise the removal of metrics that do still serve a useful purpose, despite the development of target behaviour around them (reality is not quite as black and white as Goodhart's Law suggests), and perhaps even the ''creation'' of new metrics-as-targets for the sole purpose of then removing them and collecting the bounty.

* In either case, though, even if all the metrics removed are ones that are no longer serving their intended purpose, the benefits of removing them may be outweighed by the energy devoted to finding and removing them.

The title text imagines this '''bad implemention''', leading to the creation of a new metric (metric changes per hour) and the organization identifying — and ''replacing'' — hundreds of metrics per hour, crowding out actual focus on the organization's true goals. It's the ultimate example of "change for change's sake."
* Ironically, none of the replaced metrics seem to be the one causing the issue — White Hat's original suggestion.

This comic illustrates that the thoughtless combination of Goodhart's Law and poorly designed incentives can have ruinous results for an organization.

The proper usage of organizational metrics and incentives is the focus of {{w|managerial accounting}}, a field within organizational management.

===Additional examples of Goodhart's Law===
* A school's exam results may ''suggest'' how well the school works with its pupils, but may lead to rigidly "teaching to the exams" and lead to less enjoyment and ability of life-long learning, or even flexibility in non-academic activities.
* A hospital measures inpatient ''Length of Stay'' because shorter stays save money and also free up beds for any admitted patients waiting in the ER. But if improperly incentivized, doctors may discharge inpatients too early, causing some to "bounce back" to the hospital as a costly readmission.
* A call center measures the number of calls handled per hour, but poorly decides to overly incentivize this metric to make the workers more productive; that leads workers to cut calls short, frustrating customers.

==Transcript==

:Cueball: When a metric becomes a target, it ceases to be a good metric.

2891: Log Cabin

2024-02-07T21:11:07Z

141.101.99.101: /* Explanation */

{{comic
| number = 2891
| date = February 7, 2024
| title = Log Cabin
| image = log_cabin_2x.png
| imagesize = 353x265px
| noexpand = true
| titletext = I'm sure the building inspectors will approve my design once they finally manage to escape.
}}

==Explanation==
{{incomplete|Created by a LOGARITHMIC CABIN - Please change this comment when editing this page. Do NOT delete this tag too soon.}}
This is a building {{w|floor plan}}, presumably of a {{w|log cabin}}. The odd part about it is the right half, which appears to be infinitely recursive copies of the building, like a {{w|fractal}}. The house as a whole represents a "golden rectangle" with a ratio of 1.618, with sucessively smaller living areas (further subdivided into rooms, to a common but shrunken and rotated plan) being square adjoined by a golden-rectangle of all smaller living areas in the manner of the areas defined by the classic {{w|Golden spiral}} diagram. The joke is that Randall is intentionally conflating the word "log" in the common phrase "log cabin," where "log" refers to the wood the cabin is made of, as opposed to the mathematical function of the "log" ({{w|logarithm function}}), of which the ratios here are a special case.

Every square subunit of the premises consists of a main combined kitchen/lounge area, off which leads a shower-equipped WC, two bedrooms (a double-bed one with ensuite bath-equipped bathroom, and another with a single bed; both having suitable walk-in closet space) and the door that serves as the entry into the next inwards level of the floorplan.

In the title text, Randall says that he is confident that building inspectors will approve his log cabin, assuming that they can escape. As one moves deeper into the infinite spiral of architecture, the entire log cabin ''seems'' to be a labyrinth of rooms and hallways.

It is unknown how the inspectors lost in the inner rooms would shrink in the same ratio, and would actually only have to head out through the last door they walked in through (or two, if they're currently in the en-suite) and then exit each 'main' area in turn until they exited the building itself. If they have any trouble at all (other than rescaling themselves), it would be that there is ''always'' a further inward area which they might consider needs exploring in order to fulfil their inspection routine.

== Dictionary Copyright ==

Citing a dictionary is a great example of attribution: A ''portion'' is directly quoted, with its source stated for verification purposes. Attribution is a great practice; copying without attribution isn't literal theft, but it ''is'' lazy & irresponsible, & actually detracts from the real value of the copy. Copying ''with'' attribution, on the other hand, is difficult to show any real harm from, & is arguably beneficial to all but rent-seekers. Attribution is essential! What other works, are cited with attribution, as consistently as a dictionary? Even scholarly papers seem oft-quoted without attribution... This is a disservice to both the listener, & anyone who might value the original, & potentially to the one copying. 'News' is another example of having less value without attribution... What's another good example of something that isn't as useful unless the source is cited?

2881: Bug Thread

}}

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

A bug thread is an online discussion about unintended behavior in a program, also known as a bug. Bug threads may be found on bug trackers, such as Github or Bugzilla, on technical forums such as StackOverflow, or on general product user forums.

Most bug threads have a rule to only leave a comment if you have something insightful to add{{Actual citation needed}}, such as being able to reproduce how the bug occurs or possible solutions to resolving it. In practice, this rule is often ignored and many threads end up with multiple people simply commenting that the bug still exists. Those who are perfectly content with a product have few reasons to participate in a bug thread, so those seeking help will tend to mostly read posts by the others who are, or have been, seeking help, if no one has provided a proper solution.

The exact nature of the bug in the comic is unknown, but there are multiple people reporting the problem (based upon their distinctive profile pictures), indicating that this is not a case of a rare problem where [[979: Wisdom of the Ancients|only one or two]] people have ever been known to be affected. Most of the visible posts just state the originator's inclusion in the list of those affected by the bug, either with a one word reply ("Same"), or a shorthand expression of emotion ("{{w|Like button|+1}}. So frustrating."), although another has apparently seen fit to provide three links to the specific 'solutions' that they have already seen and (unsuccessfully) tried. There appear to be no official representatives of the {{w|Developer#Computers|'devs'}}, or any other knowledgeable users, providing actual workarounds or seeking further information about the problem, at least within this small window upon the collected messages.

Although we cannot see the unreadable timestamp information on the posts, one author (the penultimate, using a [[White Hat]] image) makes the observation that the problem has now been ongoing for five years. This is followed by a [[Cueball]]-identified user proposing that this group of like-minded individuals may enjoy meeting up in the physical world (perhaps even in lieu of fixing the bug). They suggest leasing a beachfront property for a weekend, which is more suggestive of taking a break than for brainstorming possible bug resolutions (although that type of event isn't unknown). Whether this is [[Randall]], or not, his own follow-up comic commentary suggests that bonding over such adversity is as good a reason for friendship as any.

The title text reveals that the meet-up was actually attempted, suggesting that there were at least some still active (and still bug-bound?) participants of the thread. They apparently encountered (potentially unrelated) issues with an online service through which they booked the vacation venue, and have extended the general invitation (venue permitting) to several other new acquaintances who have likewise fallen foul of the holiday-home service's own problematic implementation, likely having started to similarly bond witin the bug-thread/forum where this latter issue must have stubbornly remained similarly unresolved. These new additions presumably have no interest in the original issue, but have been invited purely for social reasons.

[[979: Wisdom of the Ancients]] also refers to an online discussion thread about a bug, and [[1305: Undocumented Feature]] also involves a tech support forum which is eventually used only for socializing.

In this comic, [[Megan]] is asking [[Ponytail]] what she researches. Ponytail responds with "I'm a researcher studying gas molecules like this one" and then she indicates the air above her outstretched hand, which, indeed, does contain gas molecules.

The caption under the comic goes further by listing out things that researchers study and are, by necessity, around them either all the time, or at any time they are talking to another person, making the researchers able to respond "...like this one" when asked about their research.
* Gas molecules: Gas molecules are, like their name suggests, in a gaseous state, and thus generally share a few basic physical characteristics. A researcher would thus be able to make reference to their study of (any particular kinds of) gas molecules as, unless they happen to be researching something incredibly exotic, the gas molecules they were studying would probably share at least something with the gas molecules found in the atmosphere. A more restrictive interpretation would be that the researcher is, in fact, studying particular kinds of gas molecules that are currently found in the atmosphere, for better or for worse.
* Gravitational fields:
* Planetary magnetospheres:
* Sound waves:
* Habitable worlds:
* Languages:
* Social interactions:
* Skin microbes:

The title text adds that it would be startling for a neurologist to say "I'm a neurologist studying dreams like this one", which implies that your conversation with them is itself a dream.

141.101.99.101:

Ah, good, I was ''just'' about to tell people (on 2872's Talk page) that there was a new one... (And that we obviously need to prod the theusafBOT.) Currently, [[2872: Hydrothermal Vents]] doesn't have the 'Next' links to here, but (from last comic's experience) it might just be a matter of nudging its server-side cache a bit.

1992: SafetySat

2019-09-13T15:52:00Z

141.101.99.101: /* Explanation */ I added a short sentence related to the book What If?.

{{comic
| number = 1992
| date = May 11, 2018
| title = SafetySat
| image = safetysat.png
| titletext = During launch, in the event of an unexpected sensor reading, SafetySat will extend prongs in all directions to secure itself and any other cubesats safely in the launch vehicle until the source of the problem can be determined.
}}

==Explanation==
{{w|CubeSat}} is a standard format for small satellites that can fit in a 10×10×10 cm format with a mass of less than 1.3 kg. They have been widely used by academics for research satellites, and by both small and large companies.

CubeSats are often launched as an additional payload on commercial launches but also deployed from the {{w|International Space Station}} at the {{w|Kibo (ISS module)|Kibo-Module}} or other airlocks. All these satellites are orbiting the Earth in a low orbit and since they have no propulsion system they also become a part of {{w|space debris}} when they are out of control; Eventually they will reenter earth's atmosphere without any further hazard.

Only a few days before this comic was released the first interplanetary CubeSats called {{w|Mars Cube One}} was launched together with NASA's probe {{w|InSight}} aiming to the planet {{w|Mars}}.

One of Randall's influences in creating this comic may have been [https://spectrum.ieee.org/tech-talk/aerospace/satellites/fcc-accuses-stealthy-startup-of-launching-rogue-satellites controversy surrounding a commercial launch of a sub-CubeSat sized pico-satellite] from a launch site in India, after the company had previously been denied launch permission within the US, due to safety concerns.

There are multiple safety rules to ensure that the CubeSat cannot damage the primary payload. However, the joke in this comic is that [[Randall]]'s design seeks to break as many rules as possible.

Items clockwise from top left:

;Rare-Earth Magnets
:Violates CubeSat Design Specification Rev. 13 § 3.1.10.
:{{w|Rare-earth magnets}} are very powerful magnets that have a high likelihood of messing up the functioning of nearby electronics, like other CubeSats. Might also cause the CubeSat to stick to other satellites, as the {{w|M-Cubed}} and {{w|Explorer-1 Prime}} CubeSats did.

;BIC Mini-Lighter
: Does not conform to AFSPCMAN 91-710, Volume 3 § 10.1.3, in turn violates CubeSat Design Specification Rev. 13 § 3.1.7
:Fire source, resting on the can of crude oil. The pressurized butane could also make the lighter burst, but in space without oxygen the lighter never would ignite. And even if the inside of the CubeSat contains some oxygen in weightlessness a flame would go out very soon, of course if it set off the crude oil or the guncotton then it would not matter, as the CubeSat would be destroyed.

;SDR/{{w|Software-Defined Radio}} (Code Editable via Public Wiki)
:Violates Title 47 CFR Part 97 § 97.207(b), in turn violates CubeSat Design Specification Rev. 13 § 3.4.3.2.1
:A radio which can be programmed to broadcast and receive in a range of frequencies, and formats. Software-Defined Radios are useful for development of new or modified wireless protocols, as well as for monitoring the raw waveform data of a transmission regardless of the protocols used. The radio in this comic is stated to run firmware which can be modified from a publicly editable Wikipedia-style webpage. Since anyone could change the radio's instructions, the radio could interfere with other satellites, or with the launch vehicle. This counts as a huge security risk, as ''anyone'' could edit it.

;Laser Pointers (Fixed)
: Does not conform to AFSPCMAN 91-710, Volume 3 § 8.2.2, in turn violates CubeSat Design Specification Rev. 13 § 3.1.7
:These three laser points will effectively point in 3 different random directions, which is not safe for other objects around this Cubesat. It depends on the power of the laser pointers but, in general a laser over 5 mW can heat up and damage things given enough time.{{Citation needed|reason=Why is a laser pointer dangerous?|date=May 2018}}. Of course, with the satellite being in orbit it could potentially mess up the optical sensors of other satellites, but it would be a matter of chance. This could also be a reference to the book ''What If?'', specifically the chapter ''Laser Pointer''.

;Laser Pointer (Hubble-Seeking)
: Does not conform to AFSPCMAN 91-710, Volume 3 § 8.2.2, in turn violates CubeSat Design Specification Rev. 13 § 3.1.7
:Aiming a laser at a visible light telescope is potentially destructive to the telescope in question by damaging its optical sensors. This is because CCD & CMOS image sensors are designed to detect finite light sources, concentrated & focused by an optical lens. Lasers produce high light levels well beyond the (comparatively) very low intensity light which astronomical image sensors are designed to detect; The energy of these excess photons can heat up the circuits between rows of photosensitive cells to the point where they overheat and fuse. For much the same reason, originates the phrase "do not stare into laser with remaining eye". Unlike the fixed laser pointers above, this one would track and aim a laser at the Hubble, with potentially disastrous results.

;CFCs/Ozone-depleting CFC Spritzer
: Does not conform to AFSPCMAN 91-710, Volume 3 § 10.3, in turn violates CubeSat Design Specification Rev. 13 § 3.1.7
:{{w|Chlorofluorocarbons}} (CFCs) are fully halogenated paraffin hydrocarbons that contain only carbon, chlorine, and fluorine, produced as volatile derivative of methane, ethane, and propane. {{w|Freon}} is a common example of a CFC, and the use of CFCs has been linked to a depletion of the Earth's {{w|ozone layer}} leading many countries to ban their use. Thus spritzing CFCs in an area relatively close to the Ozone layer may be a bad idea.

;Celebratory Firework
: Violates CubeSat Design Specification Rev. 13 § 3.1.3.
: Does not conform to AFSPCMAN 91-710, Volume 3 § 13.2, in turn violates CubeSat Design Specification Rev. 13 § 3.1.7
:Explosive fire source that could hit other satellites in the vicinity; Also potentially breaking the adjacent seal & igniting the crude oil behind it, turning it into crude oil that is also on fire. Could also set off the guncotton and result in an explosion that destroys the satellite. At the very least, the off-axis position of the firework within the CubeSat would most likely send the satellite into an uncontrolled spin, upon celebratory launch.

;Volatile Epoxy Seal
: Does not conform to AFSPCMAN 91-710, Volume 3 § 10.1.3, 12.1, in turn violates CubeSat Design Specification Rev. 13 § 3.1.7
:Epoxy is a substance composed of long-chain molecules which exhibit very strong adhesive bonds. Many mixtures of epoxy are flammable & produce hazardous fumes when burned. If this particular epoxy seal fails, everything within splatter range gets coated in flammable crude oil.

;{{w|Crude Oil}}
: Violates CubeSat Design Specification Rev. 13 § 3.1.6
: Does not conform to AFSPCMAN 91-710, Volume 3 § 10.1.3, in turn violates CubeSat Design Specification Rev. 13 § 3.1.7
:{{w|Exxon Valdez oil spill}}, {{w|Deepwater Horizon explosion}}, {{w|Keystone Pipeline#Leaks and 2017 South Dakota spill|Keystone Pipeline leaks}}... need we say more? Of course the leakable volume would not be near those levels, but plenty dangerous nonetheless if it were to leak though a faulty seal or weld breakage or stress fractures. Containment and cleanup of such a leak would not be helped by the fact that such leakage could occur in orbit or even during launch. Oil spills in orbit might even present new and unexpected complications due to unusual behavior of liquids in vacuum and microgravity.

;Guncotton
: Does not conform to AFSPCMAN 91-710, Volume 3 § 10.1.3, in turn violates CubeSat Design Specification Rev. 13 § 3.1.7
:A form of {{w|nitrocellulose}}; an explosive. Could be set off by the firework, the crude oil, or the spark plug. Nitrocellulose {{w|Philae_(spacecraft)#Landing_events|does not work reliably in vacuum and possibly caused a failure of Philae space probe}}.

;Americium corners
: Does not conform to AFSPCMAN 91-710, Volume 3 § 9.1.1, in turn violates CubeSat Design Specification Rev. 13 § 3.1.7
:{{w|Americium}} is a very dense and radioactive substance. Depending on the amount of americium involved, this alone could shoot the mass over the 1.3 kg mass limit. The isotope 241Am is used in smoke detectors but also proposed for use in {{w|Radioisotope thermoelectric generator|radioisotope thermoelectric generators}} in spaceflight.

;Spark Plug
: Does not conform to AFSPCMAN 91-710, Volume 3 § 10.1.3, 10.1.4, in turn violates CubeSat Design Specification Rev. 13 § 3.1.7
:Fire ignition source, if connected to electricity; excess mass if not. The electrodes on the spark plug are next to the guncotton which could ignite if the spark plug fires. Additionally, sparks cause electromagnetic interference and electrical shorts.

;Solar Panel (Found)
:The quality of the solar panel and the power it produces would have to be investigated thoroughly before being cleared for space flight. Also, it isn't clear on the design exactly what, if anything, it is supposed to power, or if it is just excess mass.

;Batteries (eBay)
:The quality of batteries bought on auction sites can vary widely, and certain batteries exposed to conditions outside their design specifications can {{w|Battery_(electricity)#Explosion|explode or leak corrosive acids}}. These batteries might also be connected to the adjacent spark plug. Non-rechargable commercial batteries may leak or explode if a recharge is attempted, so if this is the intention of the Solar Panel, these would escalate into an even greater risk.

;Wet Sand Dispenser
:Violates CubeSat Design Specification Rev. 13 § 3.4.3
:Possible reference to the {{w|Kessler syndrome}}, which refers to a hypothetical situation wherein there are enough objects floating around in low earth orbit that collisions between objects might result in a "domino effect," each collision causing more collisions and breaking objects into smaller pieces of space debris, which increase the likelihood of further collisions. Wet sand exhibits a high grip:slip ratio, where the surface tension of the water tends to make particulates clingy. Sand (silica granules) can be very harmful to a wide variety of systems, due to its hardness & abrasive qualities. Depending upon the pattern of water sublimation in either shaded or sunlit zones, the exact behavior of various quantities of "wet sand" in low Earth-orbital space might be of interest to the designers of this and of other spacecraft.

;Title text
:Violates CubeSat Design Specification Rev. 13 § 3.4.4
:{{Wiktionary|prong|Prong}}s that extend in the event of an unexpected sensor reading at launch could damage the rocket and/or nearby CubeSats/payloads. That the CubeSat reacts to an "unexpected" sensor reading - which could include any number of readings that aren't actually a problem - is also funny, as is the fact that this is described as "safely" securing the CubeSat and any surrounding CubeSats. Along with this, it is not unlikely that this CubeSat might be the source of any internal problem that might arise; in such a situation, having such a dangerous CubeSat further secure itself would be counterproductive, if spitefully entertaining.

1864: City Nicknames

2017-07-21T17:50:22Z

141.101.99.101: /* Nicknames and Demonyms */

{{comic
| number = 1864
| date = July 17, 2017
| title = City Nicknames
| image = city_nicknames.png
| titletext = This place has so many demonyms. Northlanders. Fair Folk. Honey Barons. Lake Dwellers. Treasurers. Swamp Watchers. Dream Farmers. Wellfolk. Rockeaters. Forgotten Royals. Remote Clients. Barrow-Clerks. The People of Land and Sky.
}}

==Explanation==

Cities often have official or unofficial nicknames. For instance, {{w|St. Louis|St. Louis, Missouri}}, is known as "Gateway to the West" among several other nicknames. The nicknames typically invoke some historical or geographic feature of the city, but can sometime be opaque to those not familiar with the city. [https://www.into-asia.com/bangkok/introduction/fullname.php The full, formal name of Bangkok] includes a long list of superlatives translating as "The city of angels, the great city, the residence of the Emerald Buddha, the impregnable city (of Ayutthaya) of God Indra, the grand capital of the world endowed with nine precious gems, the happy city, abounding in an enormous Royal Palace that resembles the heavenly abode where reigns the reincarnated god, a city given by Indra and built by Vishnukarn."

Despite the skyline being clearly recognizable as St. Louis due to the {{w|Gateway Arch}}, [[Black Hat]] calls it New York City. However, the nickname he gives is neither a common New York nickname (such as "{{w|List of nicknames of New York City|The Big Apple}}") nor a St. Louis nickname. [[Megan]] tries to correct him, but it becomes clear that Black Hat is making up nicknames. Many of his suggestions are puns for real nicknames of other places.

The title text contains made up {{w|demonym}}s in the same pattern. A demonym is a word for the people who live in a particular place. They are typically derived from the name of the place (e.g. "St. Louisan" for people from St. Louis), but some regions have an {{w|Demonym#Informal|informal demonym}} that can be used colloquially by those familiar with the place to refer to its residents.

===Nicknames and Demonyms===

{| class=wikitable
! City nickname in comic

|-
| The Hot Tamale
| {{w|Hot Tamales}}
| Possibly a reference to the term [http://www.urbandictionary.com/define.php?term=big%20enchilada big enchilada] (something of great importance). In the movie [http://en.wikipedia.org/wiki/Independence_Day_(1996_film) Independence Day], the phrase "Big Tamale" is used in a similar manner as "Big Enchilada" to describe the alien fighter held at Area 51.

|-

| The Windy City
| Chicago. Possibly also [http://www.airport-technology.com/projects/incheon-international-airport/ Incheon International Airport (ICA/RKSI), South Korea]

|-
| The Gold Trombone
|
| Possibly a reference to the gold standard.

|-
| Castleopolis
| {{w|Cassopolis}}, or possibly Dictionopolis.
| Literally "Castle city." {{w|Polis}} (from the Greek πόλις for city) is commonly used as a suffix for city names, like {{w|Minneapolis}} or {{w|Alexandroupolis}}; {{w|Metropolis}} can either be a type of city, or one of the real or fictional cities bearing the name. Possibly a reference to The Phantom Tollbooth, which has both castles and cities named Dictionopolis and Digitopolis.

|-
| The Kissing Kingdom
| {{w|United Kingdom}}
| This would make a ''Very'' United Kingdom

|-
| Sandland
|
| {{w|Sandland}} is a village in northern Norway, most likely coincidentally.

|-
| The High Place
| {{w|Denver}}
|Denver is known as the Mile High City. Also, in English translations of the Old Testament, the Hebrew term במה (bamah, plural במות bamot) is rendered as "{{w|high place}}," and denotes a place of worship. In modern Jewish synagogues, the "High Place" (bimah) is the elevated platform from which the Torah is read. In Gene Wolfe's ''Free Live Free'', one character claims to come from the "High Place". The others consider this a metaphor, or simply a lie. Eventually this is discovered not to be the case.

|-
| Ol' Ironhook
| {{w|Old Ironsides}}
| Old Ironsides is a nickname for the USS Constitution (docked in Charlestown, MA). Ol' Ironhook may be a conflation of Old Ironsides (also a nickname for English Lord Protector Oliver Cromwell) with Old Hookey (a nickname for Arthur Wellesley, Duke of Wellington, English general and PM, who was also nicknamed The Iron Duke) or Old Kinderhook (a nickname for US President Martin Van Buren).
|-
| The Thousand Spires || The City of a Hundred Spires / City of Dreaming Spires|| Prague / Oxford
|-
| The Graveyard of Kings || The Graveyard of Champions / City of Kings || ''Graveyard'': Court 2 at Wimbledon, where former champions are often defeated (the playing environment is very different from Centre Court and Court One, which are larger and where games involving highly-ranked players are preferentially located). The comic was released one day after the 2017 Wimbledon Championships were finished. ''Kings'': Nickname of [[wikipedia:Lima|Lima, Peru]] and [[wikipedia:Palermo|Palermo, Sicily]]. The {{w|Valley of the Kings}} in Egypt is literally a graveyard of kings, namely the Pharaohs.
|-
| Bloomtown || [[wikipedia: Boomtown|Boomtown]] || Generic term for a town undergoing rapid growth. Used in the 2002 TV series of the same name as a nickname for Los Angeles. Might also be referring to [[wikipedia:Bloom County|Bloom County]], a comic by [[wikipedia:Berkeley Breathed|Berkeley Breathed]], or Dublin, as the setting for Ulysses by James Joyce.
