:[Cueball stands in front of a whiteboard full of formulas and diagrams, White Hat is watching him.]
:White Hat (in thought bubble): Amazing watching a physicist at work, exploring universes in a symphony of numbers.
:White Hat (in thought bubble): If only I had studied math, I could appreciate the beauty on display here.

:Cueball (in thought bubble): Oh no. This has '''two''' unknowns. That's gonna be really hard.
:Cueball (in thought bubble): Ughhhhhhh.
:Cueball (in thought bubble): '''''Think.''''' There's gotta be a way to avoid doing all that work...

166: Misusing Slang

2019-08-17T04:11:18Z

172.69.170.112: /* I think that the term veteran sounds off when put right next to the term pwned /*

{{comic
| number = 166
| date = October 4, 2006
| title = Misusing Slang
| image = misusing_slang.png
| titletext = It slowly dawns on us that our parents knew exactly what they were doing.
}}

==Explanation==
[[Randall]] expresses excitement for the time in the future where he can intentionally misuse modern-day slang in order to make nearby teenagers feel uncomfortable. He illustrates this by using the word "pwned," the past tense of "pwn" (from "own," as in to defeat completely): "The noob was pwned by the pro."

Many teenagers believe their parents to be not "with the times," but Randall suggests that parents actually ''do'' know what the words mean, but are acting otherwise in order to mess with their heads for their personal amusement. The title text reinforces this, as every generation has had some form of slang that they used, and it could be possible that this practice has been continued for a good while. It also suggests that the parents of teenagers may be "pwning" their children by intentionally misusing these modern-day slang.

==Transcript==
:The best part of getting older is gonna be intentionally misusing slang around teenagers just to watch them squirm.
:Cueball: Oh man, that song is so pwned!
:Teenager: ''twitch''

Disappearing Sunday Update

2019-08-04T23:38:09Z

172.69.170.112: /* Initial Explanation */

{{comic
| number = 2185
| date = August 5, 2019
| title = Disappearing Sunday Update
| image = disappearing_sunday_update.png
| titletext = This comic won't exist in the archives. NOTHING IS REAL.
}}

==Explanation==
{{incomplete|Created by a BOT. Please mention here why this explanation isn't complete. Do NOT delete this tag too soon.}}
The comic claims to be a special Disappearing comic that will disappear Monday August 4th, and is an advertisement for The upcoming book "How To".
This includes a drawing of the cover, on set of pages, and a sampling of the table of contents of the book.
The second part of the comic apologizes for various bots that automatically catalog xkcd comics that might break because of this special comic.
This website is one example assigning the comic a number of 2185 despite the comic not having a designated number. The comic even broke the xkcd site its self as the previous comic (2184) has a next button that links to comic 2185 (which does not exist) and displays a [http://http.cat/404 404] error.
One of the bot methods mentioned may be in reference to [http://www.xkcd.com/2180 2180 : Spreadsheets] where Queball debates making a real program to do a task, or to use a spreadsheet instead.

~SPECIAL DISAPPEARING SUNDAY COMIC~

I'm posting this ephemeral sunday update to let you know that I wrote a book! It's a guide to solving everyday problems in terrible ways using science.

It comes out next month, and it's available for preorder now.

The cover looks like this

and the inside looks like this.

Chapters include:
How to charge your phone
How to throw a pool party
How to move
How to build a lava moat
How to ski

You can learn more and preorder it at xkcd.com/how-to

and read an excerpt at blog.xkcd.com

If you read xkcd through unusual means, including apps, custom screen-scraping systems, google reader clones, twitter bots, bash scripts, gopher portals, lynx-based ascii art browsers, third-party sceond life feeds, rfc 2549, or massive google docs sheets full of =importhtml() and =image() formulas, I hope this ephemeral ghost comic doesn't break them too badly.

It will disappear with the normal monday update.

(At least, I think it will. I've never tried this before. So I'm honestly not sure what the server will do.)

730: Circuit Diagram

2019-07-29T18:58:04Z

172.69.170.112: Added an extra comment to the circuit diagram explanation.

{{comic

| titletext = I just caught myself idly trying to work out what that resistor mass would actually be, and realized I had self-nerd-sniped.
}}

==Explanation==
Another fine example of [[356|nerd sniping]].
There are pieces of circuit diagrams, road maps, chemical diagrams, and other things all mixed in.

A cloverleaf junction has previously been used in comic: [[253: Highway Engineer Pranks]].}}
{{circuit-diagram-part|X=184|Y=12|W=87|H=63|image=circuit_diagram-184-012-087-063-battery.png|text=A battery. The voltage of square root of two is strange, but getting about 1.41412... volts is not unheard of. This could also indicate an [[wikipedia:Root_mean_square|RMS]] voltage, although this is unlikely given that this is a DC power supply and not an AC generator. The marked polarity is also the reverse of what is implied by the symbol (where the larger terminal is positive). A possible reference to [[567: Urgent Mission]].}}

The pin connected to "?" is the CTRL pin on a normal 555 timer, which would typically be connected to ground (via a decoupling capacitor) if used at all; the implication here seems to be that it would be connected directly to Hell itself.}}

2177: Gastroenterology

2019-07-17T17:37:33Z

172.69.170.112: I don't think Ponytail is lying

{{comic
| number = 2177
| date = July 17, 2019
| title = Gastroenterology
| image = gastroenterology.png
| titletext = "Mostly it means that I'm acutely aware that the kid one table over coughed as the server walked past with our food."
}}

==Explanation==
{{incomplete|Created by a GASTROENTEROLOGIST. Please mention here why this explanation isn't complete. Do NOT delete this tag too soon.}}

[[Ponytail]] and a guy wearing a scrubs hat, seemingly being scientists as Ponytail wears a lab coat, are pursued by some offscreen people, at whom Ponytail will throw a bottle filled with probiotic and antibiotic substances, which, after being shook and thrown, surprisingly results in an explosion. This may refer to {{w|annihilation}}, a reaction between particles and antiparticles, which produces important energy, hence the explosion; the particles being the probiotic matter and the antiparticles being the antibiotic matter, even though annihilation usually implies subatomic particles.

In the last panel, the above is revealed to be some kind of action fantasy. Ponytail's reality is far more mundane: she is sitting at lunch and talking with Megan, the latter asking what Gastroenterology (Ponytail's job) is. Ponytail answers it is mostly boring paperwork.

[https://gi.org/patients/gi-health-and-disease/what-is-a-gastroenterologist/ Gastroenterology] is the study of the normal function and diseases of the esophagus, stomach, small intestine, colon and rectum, pancreas, gallbladder, bile ducts and liver.

In the title text, Ponytail adds that her work makes her aware of a child coughing as the server was bringing food at the restaurant table, exposing the food to possible germs.

==Transcript==
{{incomplete transcript|Do NOT delete this tag too soon.}}
Cueball: Hurry, they're right behind us! 
Ponytail picks up a probiotic and antibiotic, combining them into a single jar. 
Ponytail shakes the jar three times before throwing it, presumably at the off-panel pursuers. 
There is an explosion off-panel as Cueball and Ponytail continue to flee. 
Megan: So what's gastroenterology like? 
Ponytail: Pretty boring. Lotta paperwork.

I was under the impression that 'millenials' were those born in the 90s, in between gen y and gen z. I think there is a 'slight' trend that my generation has trouble 'growing up' even as adults. Many friends, if they haven't had kids they might still be living at home. Some even have kids and are still living with their parents. Myself, I don't see why a family structure couldn't work that way and still be healthy, I think the 'issue' comes from the older generations trying to keep the societal norms steady, and in the 1950s, when a boy turned 18 he became a 'man' and was promptly kicked out of the house, like a bird from a nest, or something like that...

In fairness to White Hat, one might plausibly assume from the word "millennial" that it was meant to refer to people born around the turn of the millennium, or people born in the current millennium which is still fairly new as millennia go. It's not obvious that a person born 18 or 19 years before the turn of the millennium ''is'' supposed to be a millennial, while a person born 1 year before or 1 year after the turn of the millennium isn't. --[[Special:Contributions/172.69.90.34|172.69.90.34]] 15:25, 19 June 2019 (UTC)

==Explanation==
{{incomplete|Created by a MILLENIAL. Please mention here why this explanation isn't complete. Do NOT delete this tag too soon.}}

According to [[1962: Generations|the definitive chronology of generations]], millenials are born between 1982 and 1999. Those born in 1982 reached adulthood (18 years) in 2000. As of writing of this comic (mid 2019), this is about 20 years ago. When the term became widespread around 2012, people born in 1982 were 30 years old, so the image was popularized of millenials as "college kids". The definition of the word in everyday usage seems to be expanding so that it can now includes those that were originally Gen Y, some of Gen X, as well as the gap in between them, while still including current college kids.

In this strip, [[White Hat]] expresses a sentiment of prejudice against millennials, claiming they aren’t prepared for “the real world.” This is a sentiment that sometimes can be found among those of older generations.
However, [[Cueball]] refutes this by saying that many millennials have been adults for almost 20 years, and those that had kids early on are taking them to college. This is due to another common misunderstanding, where the definition of “millennial” has changed so much, and expanded so often, that nobody really knows what it means anymore.

[[White Hat]] refuses to accept this, saying millennials ''are'' the college kids, to which [[Cueball]] says that maybe White Hat is the one not growing up and accepting that millennials are, in fact, adults. The title text builds on this, complaining that [[Randall]] has been having these discussions for over a decade.

The title text contains a subtle pun with Gran-negative, where the bacterial term is Gram-negative, but instead is referring to Granny-Smith apples - hence, gran-negative. [[User:Ianrbibtitlht|Ianrbibtitlht]] ([[User talk:Ianrbibtitlht|talk]]) 18:06, 10 June 2019 (UTC)

Antibiotics weren't my first thought on reading this comic, but rather mosquitoes, which have an amazing tendency to overcome everything we throw at them. There was an article a day or two ago about introducing spider venom into fungus to try a new approach against them.

We could put our apples on a messaging site that posts to an uncensorable blockchain like https://memo.sv/ so that everybody can reuse others on doctors that haven't seen them yet. What do you think? I was also thinking if a strong AI were developed, it could build new apples as needed. Maybe an AI could be made rapidly by having it learn to predict its own behavior from its code. But you wouldn't want it to accidentally take over the world, so it could have a primary task of being interviewed in an empathic way, answering for example, "are you happy with how fulfilled your need to nurture and empower life is?" Answering this question in depth might stimulate it to understand these concepts, and the response would give the interviewer lots of avenues to understand and verify it further. By the way, there's a 30-page booklet on a technique used to resolve wars rapidly [https://gateway.ipfs.io/ipfs/QmdFVjYwgeuUpw83hBB74Wy4js8SrmmNxt8U2MkdRA2f7m/Books/We%20Can%20Work%20It%20Out:%20Resolving%20Conflicts%20Peacefully%20and%20Powerfully.pdf here].

172.69.170.112: That's not what being a game tester is like.

Playtesters procrastinate too? —NT

Weeellll - that's not really accurate Mr Munroe. I've worked (as a software engineer) in the video game industry for years. One of the biggest myths is that QA testers get paid to play video games. In fact, they don't REALLY get to play the game much at all. For most of the development cycle, there is only one or two working levels - crap graphics and crash-prone software. So they "play" in a way that is deliberately quirky in order to push the code in directions it wasn't meant to be pushed - so they can see if it crashes. They have to pay careful attention. Then they file a bug report (Oooh! Paperwork! Form filling!) and try to do exactly what they did *again* so they can explain how to make it happen. Then they go off and hunt for another bug. Once a bug is marked as "fixed" by the software team - they have to try to make it happen again - to be sure it was fixed - then do other SIMILAR things that might trigger that bug. Once we all agree that the bug is fixed - it goes on the "regression list" - which means you get to repeat the exact actions you did over and over - maybe once a month - but certainly before each Alpha/Beta/Gold release. Multiply this by hundreds of bugs - and that's what you do all day. Sometimes a software guy will pop their head around the door and say "Could someone pick up that weapon and move it through every single doorway in the entire game and see if you get stuck in any of them! K'Thanks!".

What you DON'T do is play the video game all day...and even if you did - over a typical 3 year development cycle, you'd be SO sick of it.

Hence, it's not at all unreasonable that a play tester would have fun actually playing the game.

No idea whether we should put this into the explanation part.
