(Cueball sits in front of his computer.)

Cueball: Can you take a look at the bug I just opened?

Off-panel: Uh oh.

Off-panel: Is this a normal bug, or one of those horrifying ones that prove your whole project is broken beyond repair and should be burned to the ground?

Cueball: It's a normal one this time, I promise.

Off-panel: OK, what's the bug?

Cueball: The server crashes if a user's password is a resolvable URL.

Off-panel: I'll get the lighter fluid.

295: DNE

2016-04-29T02:38:19Z

173.245.54.252: /* Explanation */

{{comic
| number =295
| date =July 27, 2007
| title =DNE
| image =dne.png
| titletext =I've seen advertisers put their URLs on chalkboards, encircled with a DNE. They went unerased for months. If you see this, feel free to replace the URL with xkcd.com.
}}

==Explanation==
DNE stands for "do not erase", and is commonly used on school whiteboards to let the sanitation staff and other teachers know not to erase that particular area of the board. DNE circles often encompass important information such as test dates or the teacher's name.

It is easy to see how leaving things marked with DNE can become automatic for anyone often erasing boards, so that they don't notice what the message actually says, or reflect on whether the DNE-marking is reasonable for it. [[Cueball]]'s dissatisfactory note is not very subtle, but [[Randall]] notes in the title text that advertisers have successfully used the same tactic for less conspicuous {{w|URL}}s to their sites. He also kindly asks you to replace those messages with xkcd.com to get some free advertising.

On the bottom half of the board is a crossed out 2x2 {{w|Matrix (mathematics)|matrix}}, and two {{w|Function (mathematics)|functions}} for {{w|Exponential decay| exponential decay}}.

==Transcript==
:[Cueball is in an empty classroom writing on the whiteboard. In the top right corner in large print is written "Fuck This Place!". It is circled, and underneath he is writing "DNE".]

I believe that the line about having faith is also supposed to be a dig at magical thinking in science. Cueball may "know" that the experiment works because he's seen it done, but he hasn't thought it through enough to realize that it doesn't work from the other direction.

1667: Algorithms

2016-04-13T16:18:48Z

173.245.54.252:

{{comic
| number = 1667
| date = April 13, 2016
| title = Algorithms
| image = algorithms.png
| titletext = There was a schism in 2007, when a sect advocating OpenOffice created a fork of Sunday.xlsx and maintained it independently for several months. The efforts to reconcile the conflicting schedules led to the reinvention, within the cells of the spreadsheet, of modern version control.
}}

==Explanation==
{{incomplete|Still need an explanation of the title text, and perhaps some expanded definitions of the listed algorithms.}}
An algorithm is a basic set of instructions for performing a task, usually on a computer. This comic lists some algorithms in increasing order of complexity.

At the simplest end is '''left-pad''', or adding filler characters on the left end of a string to make it a particular length. In many programming languages, this is one line of code. This is possibly an allusion to a [http://www.haneycodes.net/npm-left-pad-have-we-forgotten-how-to-program/ recent incident] when {{w|Npm (software)|NodeJS Package Manager}} [https://www.techdirt.com/articles/20160324/17160034007/namespaces-intellectual-property-dependencies-big-giant-mess.shtml angered a developer] in its handling of a trademark claim. The developer unpublished all of his modules from NPM, including a package implementing left-pad. A huge number of programs depended on this third-party library instead of programming it on their own, and they immediately ceased to function.

Next is '''{{w|Quicksort}}''', an efficient way to sort a list of items.

'''{{w|Git (software)|Git}}''' is a {{w|version control}} program, i.e., software that allows multiple people to work on the same files at the same time. When someone finalizes ("commits") their changes, the version control program needs to figure out how to join the new content with the existing content. This process is called '''{{w|Merge (version control)|merging}}''', and the algorithm for it is anything but simple.

A '''{{w|self-driving car}}''' is what it says on the tin: an automobile with sensors and software built into it so that it can maneuver in traffic autonomously, i.e. without a human controller. Various companies have been working on such vehicles for many years now, and while they're further along now than would have been imaginable even a couple of years ago, we're still far away from the dream of hopping in a driver-less taxi and sitting back as the car itself navigates to where we want to be. Recently [[Randall]] has made several references to self-driving cars, for instance in [[1559: Driving]],[[1623: 2016 Conversation Guide]] and [[1625: Substitutions 2]].

The '''{{w|Google Search}} backend''' is what enables you to type "what the heck is a leftpad algorithm" into your browser and have Google return a list of relevant results, including correcting "leftpad" to "left-pad", ignoring the "what the heck" part, and sometimes even summarizing the findings into a box at the top of the results. Behind all that magic is a way to remember what pages the internet contains, which is just a mind-bogglingly large quantity of data, and an even more mind-numbingly complex set of algorithms for processing that data.

The last item is the punchline: a sprawling {{w|Microsoft Excel|Excel}} {{w|spreadsheet}} built up over 20 years by a church group in Nebraska to coordinate their scheduling. Spreadsheets are a general {{w|end-user development}} programming technique, and therefore people use Excel for all sorts of purposes that have nothing to do with accounting (its original purpose), including one guy who made a [http://arstechnica.com/gaming/2013/04/how-an-accountant-created-an-entire-rpg-inside-an-excel-spreadsheet/ role-playing game that runs in Excel]; but even that doesn't approach the complexity that develops when multiple people of varying levels of experience use a spreadsheet over many years for the purpose of coordinating the schedule of several coordinated groups.

The scheduling of tasks over a group of resources (a.k.a. the ''{{w|nurse scheduling problem}}''), while respecting the constraints set by each person, is a {{w|NP-hardness|highly complex}} problem requiring stochastic or heuristic methods for its resolution. Here, the algorithm would be further complicated by being solved by inexpert users over a spreadsheet model without using engineering practices. The hyperbole here is in thinking that such combination of circumstances would produce complexity far over that required to drive a car or sort the public contents of the internet. Most churches meet on Sunday morning, so there's no actual complexity in organizing that service, however, with different members involved in a wide variety of activities within and without the church, and the classrooms available to the church on Sunday itself, (just scheduling the choir practice times to coordinate with everyone's work schedules is very possibly impossible, especially if two people share the same occupation, and one is the relief for the other,) can indeed be daunting. In addition, there would likely be assorted committee meetings during the week.

In the title text, part of the spreadsheet's complexity is described as originating from different versions of the file for different programs. The words used like {{w|schism}} and {{w|sect}} are normally used in context of religions splitting into groups about differences in beliefs. In this case, the split seems to have been not over a {{w|theology|theological}} issue, but about the use of {{w|open-source software|open-source}} vs. {{w|proprietary software|proprietary}} software, disagreements about which are often compared to religious debates.

Out of curiosity (I'm new to the standards of explainxkcd), are out of date pages considered incomplete? Or is it up to editors to chose when to update a pages explination. I would assume the former, except that would make maintaining the pages significantly more difficult. Also, referencing the Linux takes over. Since Android is now a part of the libux kernel,should thia be changed? It would definently put linux over the 50% mark.

I would correct the entry in 2014 that says that the Taliban are the organisation responsible for the September 11th attacks. The more accurate explanation would be that The US believed Al Qaeda (the real organisation responsible) were hiding out in Afghanistan and that defeating the Taliban, and bringing stability to the country was an important stepping stone towards finding Osama Bin Laden. Of course we now know he was in Pakistan all along, but still that was the original rationale for invading Afghanistan.--[[Special:Contributions/141.101.98.192|141.101.98.192]] 15:27, 15 December 2014 (UTC)

This further details stuff is wrong about the comic. The lines are just random answers to Google searches. There is no explanation.

As of 2014 I have noticed that a lot of US sites are moving from html to closed sources such as Adobe so the quote: "The prediction about GNU/Linux Operating Systems is ambiguous" is now fighting through government agencies.

“The prediction about GNU/Linux Operating Systems is ambiguous, as Android (based on Linux) constitutes nearly 50% of the mobile OS market” — GNU/Linux refers to an operating system consisting of the GNU userland toolchain over the Linux kernel. Android is based on Linux but not GNU, therefore, it is irrelevant in GNU/Linux context. [[Special:Contributions/108.162.230.107|108.162.230.107]] 11:18, 23 January 2015 (UTC)

1645: Toasts

2016-02-19T18:40:05Z

173.245.54.252: /* Explanation */ This kind of play on words is not a Spoonerism

{{comic
| number = 1645
| date = February 19, 2016
| title = Toasts
| image = toasts.png
| titletext = Platonic solids for my real friends and real solids for my platonic friends!
}}

==Explanation==
{{incomplete|There may be more jokes and more on the different words.}}
A {{w|Toast (honor)|toast}} is a ritual in which a drink is taken as an expression of honor or goodwill. The term may be applied to the person or thing so honored, the drink taken, or the verbal expression accompanying the drink. Thus, a person could be "the toast of the evening," for whom someone "proposes a toast" to congratulate and for whom a third person "toasts" in agreement

The comic is based on the quote {{w|Champagne for My Real Friends, Real Pain for My Sham Friends}} which, though often attributed to the painter {{w|Francis Bacon (artist)|Francis Bacon}} or to {{w|Tom Waits}}, is a toast dating back to at least the nineteenth century. It is also the entire title of a [https://www.youtube.com/watch?v=E7q9i6KYmzQ song], the {{w|From_Under_the_Cork_Tree#Track_listing|ninth track}} on {{w|From Under the Cork Tree}}, a 2005 album by {{w|Fall Out Boy}}.

The comic plays on a permutation structure between two words, yielding puns with various effects. In this comic eight persons drink a '''toast''' for their "real friends" and then for some other type of "friends". For the real friend they wish them to have one specific thing. This something is a word (X-Y) that can be split up in two meanings (X and Y), where one of them are then put in front the word friend, to explain what type of friends they are now toasting (often a bad/false type of friend) and then these friends get a wish for having what the word that are left of the original word means: "X-Y for my real friends and real Y for my X friends"

The first example is a typical toast, in Champagne, where this word can be split in the two phonetically similar words Sham and Pain, and the sham friends then get pain. [[#The toasts|Below]] all examples (including the ninth from the title text) are listed with explanation for all words.

===The toasts===
*''Champagne'' sounds like a combination of the two words ''sham'' and ''pain''.
**{{w|Champagne}} is an expensive sparkling wine.
**[https://en.wiktionary.org/wiki/sham Sham] friends means false friends.
**{{w|Pain}} is not so nice to hand out.
***So [[Cueball]] toast his real friends in Champagne and wishes real pain to his false friends.
*''Pseudopods'' can be divided into ''pseudo-'' and ''pods''.
**{{w|Pseudopods}} (which translates to "false feet") are temporary cytoplasm-filled parts of the cell wall that are able to change their form in order to move. They are used in some eukaryotic cells to move around or to eat. Most cells that do this are called {{w|Amoeba|amoeboids}}. The {{w|Amoeba (genus)|amoeba}} is a common example.
**{{w|Pseudo-}} (lying, false) is used to mark something that superficially appears to be (or behaves like) one thing, but actually is another.
**{{w|Pods}} or {{w|pod}} is not clearly defined. It could refer to {{w|Glossary_of_plant_morphology#Fruit_types|seedpod}} – a dry dehiscent fruit containing many seeds. Pods, both malevolent and benignant, appear in many works of SF and Fantasy. In this toast, it could refer to the pods in {{w|Invasion of the Body Snatchers}}, which take over or replace humans with alien creatures. It might refer to the dangerous podracers in {{w|Star Wars Episode I: The Phantom Menace}}. It could also refer to the [http://thehungergames.wikia.com/wiki/Pod pods] from {{w|The Hunger Games}} where they are specifically used as the city defense in the last book {{w|Mockingjay}}.
***So the blonde girl will give her real friends a special part/adaptation of the amoeba (Doesn't everyone wish they had pseudopods? I'm sure Randall does.), while her pseudo-friends receive real pods with intricate ways to kill them.
*''Petticoats'' sounds like a combination of the two words ''petty'' and ''coats''
**{{w|Petticoats}} or underskirt is an article of clothing; specifically an undergarment to be worn under a skirt or a dress.
**[https://en.wiktionary.org/wiki/petty Petty] means small (in rank of importance), insignificant or narrow-minded. See for instance {{w|petty crime}}.
**A {{w|Coat (clothing)|coat}} is a garment worn by both men and women, for warmth or fashion.
***So [[Megan]] will hand out undergarments for her real friends (a very personal gift) and coats for her less important/insignificant or narrow-minded friends (they seem to be the luckier ones here).
*''Loosestrife'' can be divided into ''loose'' and ''strife''.
**{{w|Loosestrife}} is a common name for plants within two different genera (which are not related): {{w|Lythrum}} (example: {{w|Lythrum salicaria|purple loosestrife}}) and {{w|Lysimachia}} (example: {{w|Lysimachia ciliata|Fringed Loosestrife}})
**[https://en.wiktionary.org/wiki/loose Loose] in this case means free from restraints, as the opposite of {{w|close friend}}. Loose can also refer to being sexually promiscuous, especially when used as an adjective for people.
**[http://www.merriam-webster.com/dictionary/strife Strife] refers to bitter, sometimes violent, conflict or discord.
***So the "brunette" girl (i.e. similar hair but less dark than Megan) will give her real friends flowers and her promiscuous friend she wishes to end up in a real violent conflict.
*''Ladybugs'' can be divided into ''lady'' and ''bugs''.
**{{w|Ladybugs}} (or Ladybird) is a family of insects common all over the world. They are considered cute: [https://pinterest.com/lisalynnburns/lady-bugs-so-cute/], [http://photobucket.com/images/cute%20ladybug], [http://www.zazzle.com/cute+ladybug].
**{{w|Lady}} is a civil term of respect for a woman, specifically the female equivalent to {{w|gentleman}} or {{w|lord}}, but in many contexts a term for any adult woman.
**{{w|Bugs}} in this case refer to to {{w|insects}} or {{w|arachnids}}
***[[Hair Bun Girl]] will give ladybugs for her real friends (a cute type of bug that most people are not afraid of), and real bugs (beetles, flies or spiders) to her lady friends. This is not necessarily all her female friends, it could be only those that are {{w|Lady#British_nobility|noble}} or at least think they are more important and thus would like to be called lady. No matter what most ladies dislike most types of animals that are commonly referred to as bugs.
*''Single-payer'' can be divided into ''single,'' and payer, a word that rhymes with ''player''. In this case this word is then put together with real to form the word ''RealPlayer''.
**{{w|Single-payer}} refers to single-payer healthcare, a system in which the state, rather than private insurers, pays for all {{w|healthcare}} costs, a system used in several countries, but not so far in the US, although {{w|Barack Obama}} has gone some of the way with {{w|Patient Protection and Affordable Care Act}}.
**{{w|Single person|Single}} refers to a person who is not in a relationship or is unmarried.
**{{w|RealPlayer}} is a cross-platform media player app, developed by RealNetworks. It is compatible with numerous container file formats of the multimedia realm. In the past it has been {{w|RealPlayer#Reviews_and_critiques|criticized}} for containing adware and spyware. This was back from 1999 and up to the 2004 version.
**It is specifically not the word ''{{w|Single-player video game|single-player}}'' that is used! this word could refer to video games that only one player can play at a time, or when choosing to play single-player in a game where more could have played. ''RealPayer'' is not a word in use.
***[[White Hat]] thus wishes that his real friends have access to state-funded health care, and all his single friends will get RealPlayer. Since [[White Hat]] is normally benevolent, if naïve, he may imagine that RealPlayer will help his single friends enjoy Internet media, when they are home alone. Maybe he wishes to impress these singles with a free app as a present in the hope that he {{w|Get Lucky (Daft Punk song)|gets lucky}}. (If it has been [[Hairy]] this would have seemed very likely… see [[1178: Pickup Artists]]. White Hat has not previously displayed these tendencies too clearly). As mentioned there have been some issues with RealPlayer in the past, but it has stayed on the market for more than a decade. However, since it has {{w|RealPlayer#Current_Status|recently been change}} into ''RealTimes'' it may not be so cool a gift anyway. Also White Hat might wish to give away the old spy ware version of RealPlayer. But as opposed to most of the special friends, single-friends is not in it self negative, especially not if you are yourself single. So no direct reason to make bad wished for single friends as opposed to sham friends.
*''Tumbleweeds'' sounds like a combination of the two words ''Tumblr'' and ''weed''.
**{{w|Tumbleweed}} is a structural part of the above-ground anatomy of a number of species of plants, a {{w|Diaspore (botany)|diaspore}} (of seeds) that, once it is mature and dry, detaches from its root or stem, and tumbles away in the wind. The tumbleweed's {{w| Tumbleweed#Symbolism|association}} with the Western film genre has led to a highly symbolic meaning in visual media.
**{{w|tumblr}} is a microblogging platform and social networking website
**{{w|Weed}} is a plant considered undesirable in a particular situation but in this case it refers to {{w|Cannabis (drug)|Cannabis}} also known as marijuana and many other names including weed and would be used (again in this comic) as a {{w|psychoactive drug}}, i.e. to {{w|getting high|get high}}.
***[[Ponytail]] thus gives her "real" friends a western movie symbol, that will spread seeds over their house, but with her friends on her favorite blogsite Tumblr she will share her expensive weed.
*''Fauxhawks'' can be divided into ''faux'' and ''hawks''
**{{w|Mohawk_hairstyle#Fauxhawk_variants |Fauxhawks}} copies the style of a {{w|Mohawk hairstyle}}, but without shaving the sides of the head and not extending past the peak of the cranium.
**{{w|Faux}} is a French word for "false".
**{{w|Hawks}} is a common name for some small to medium-sized diurnal birds of prey, widely distributed and varying greatly in size.
***[[Beret Guy]] thus wishes to cut his real friends hair in a very special way, maybe to his liking and thought of as a favor, but not necessarily liked by all his friends, cause although Beret Guy is weird, it seems that those around him are not. His false friends can have a predatory bird (maybe coming after them), but rather knowing Beret Guys love of all things, just as a present of something he likes, like animals.
*'''Title text:'''
*''Platonic solids'' can be divided into ''platonic'' and ''solids''
**{{w|Platonic solids}}: In three-dimensional space, a platonic solid is a regular, convex polyhedron. It is constructed by congruent regular polygonal faces with the same number of faces meeting at each vertex. Five solids meet those criteria, and each is named after its number of faces: Tetrahedron (a.k.a. "Regular triangle-based pyramid"), Hexahedron ("Cube"), Octahedron (can be considered the union of two square-based pyramids, base-to-base), Dodecahedron and Icosahedron.
**[https://en.wiktionary.org/wiki/platonic Platonic] means ''not sexual in nature'' as in {{w|platonic love}}, which is a type of love that is celibate and non-sexual. Typically friends would not be called platonic, but they are normally also not the opposite.

1641: Hot Dogs

2016-02-12T04:51:28Z

173.245.54.252: /* Explanation */

{{comic
| number = 1641
| date = February 10, 2016
| title = Hot Dogs
| image = hot_dogs.png
| titletext = Okay, I'm just gonna order pizza, and let's never talk about this again.
}}

==Explanation==
A common staple of trite comedy is "why do hot dogs come in packages of ten but hot dog ''buns'' in bags of eight?" The phenomenon is mildly frustrating for the consumer, as it often leaves leftover food. The most sinister result is the subsequent purchase of more buns, followed by more hot dogs, followed by more buns, over and over again until forty total hot dogs have been eaten (in a cycle similar to that shown in [[140: Delicious]]).

The actual reason for the mismatch between hot dogs and buns, according to both [http://www.todayifoundout.com/index.php/2014/11/dont-hot-dogs-hot-dog-buns-come-packs-number-start/ Karl Smallwood] and [http://www.straightdope.com/columns/read/560/why-do-hot-dogs-come-10-to-a-pack-while-buns-are-8-to-a-pack Cecil Adams], is that meat packers like things that come in pounds and bakers hate things that come in tens. Nonetheless, some smaller companies are starting to offer bags of ten buns, and several brands of hot dogs sell in packages of eight.

Here, [[Cueball]] attempts to raise the question as he is standing with a package of {{w|hot dogs}} in one hand and a bag of {{w|Hot dog bun|buns}} in the other hand (presumably for their dinner), but a person offscreen interrupts him mid sentence and mentions {{w|condoms}} instead of buns. Cueball mulls the subject over in his mind, and when he realizes his friend is putting hot dogs in condoms, he is promptly grossed out.

The title text makes it clear that Cueball's new found association of [http://www.snopes.com/college/risque/hotdog.asp hot dogs with sexual activity], has put him totally off the idea of eating any of them this evening, and he suggests ordering {{w|pizza}}, which he then can hope will not be used for (nsfw)[http://www.cosmopolitan.com/sex-love/advice/a5943/pizza-sex-tip/ similar comparisons]… Cueball also asks that he and his friend never discuss this conversation again, due to the situation's awkwardness and uncomfortable subject matter.

==Transcript==

:[Cueball is standing in the frame holding a bag and a package of hot dogs.]
:Cueball: Hey, why do hot dogs come in packages of ten-
:Offscreen: -But condoms come in strips of six? I know, right?!

Talk:1639: To Taste

2016-02-05T14:55:35Z

173.245.54.252:

Seasoning is not an intermediate process which can't be repaired/re-done. you're left with an edible dish before and after. You add seasoning in small incremental steps, and the quality of the dish, or appropriateness of the taste improves monotonically, and additively. On the other hand, baking something for 5 minutes, and then another 5 minutes isn't the same as baking it for 10 minutes. [[Special:Contributions/162.158.49.78|162.158.49.78]] 09:54, 5 February 2016 (UTC)
: Yeah, but a beginner should be given an idea of what a basic incremental step is supposed to be, based on the number of servings in the recipe. One pinch? One (tea/table)spoon? One cup? One jug? One crate? - [[Special:Contributions/141.101.70.23|141.101.70.23]] 11:38, 5 February 2016 (UTC)
: Usually when it's said ''to taste'', which I guess corresponds to the Italian ''quanto basta'', it's referring to small amounts, so a beginner could just add a pinch per time until he finds the flavor is good. Whenever it's unnecessary, recipes shouldn't be specific; you don't have to grill a steak for exactly 5 or 10 minutes, just until it has the color and looks of a steak you think you may like; if you boil pasta, you taste a bit once a minute until the texture is good. --[[Special:Contributions/188.114.102.249|188.114.102.249]] 12:25, 5 February 2016 (UTC)
::: The joke is that this kind of knowledge is implied in recipes, it isn't spelled out. Which can be a problem for beginners. And good luck trying that approach when baking spiced bread. Or manufacturing soufflé. ;) [[Special:Contributions/162.158.114.138|162.158.114.138]] 13:15, 5 February 2016 (UTC)
::: Luckily, there are pastas which specify how long you are supposed to cook them on the package. Especially useful in case of those "fast" ones. -- [[User:Hkmaly|Hkmaly]] ([[User talk:Hkmaly|talk]]) 13:57, 5 February 2016 (UTC)
: "Appropriateness" increases "monotonically" ... until it decreases again. :D [[Special:Contributions/162.158.114.138|162.158.114.138]] 13:15, 5 February 2016 (UTC)

I can't tell if Randall is reading too many cookbooks or if he just has... Too many cooks[[Special:Contributions/108.162.221.54|108.162.221.54]] 13:46, 5 February 2016 (UTC)

Maybe he obtained enough sugar so his sample size would be sufficient for scientific experimentation on what to taste means.[[User:Thaledison|Thaledison]] ([[User talk:Thaledison|talk]]) 14:02, 5 February 2016 (UTC)

In my experience, the instructions "add _____ to taste" usually are referring to salt, not sugar. And from comic #1637, we all know Cueball has access to virtually an unlimited quantity of salt! [[Special:Contributions/173.245.54.252|173.245.54.252]] 14:55, 5 February 2016 (UTC)Sam

1635: Birdsong

2016-01-27T14:45:16Z

173.245.54.252: /* Explanation */

{{comic
| number = 1635
| date = January 27, 2016
| title = Birdsong
| image = birdsong.png
| titletext = Maybe if I put it in a box for a while with a speaker playing some pleasant pastoral music, I can reprogram it.
}}

==Explanation==
The comic shows [[Cueball]] walking along singing with a bird in the background; Cueball is apparently enjoying the perfect morning and the birdsong. In the next panel, it becomes apparent that the bird is actually singing the words to the song "{{w|Smooth (song)|Smooth}}" ([https://www.youtube.com/watch?v=6Whgn_iE5uc official video]) by {{w|Santana (band)|Santana}} featuring {{w|Rob Thomas (musician)|Rob Thomas}}. The bird's singing begins to annoy Cueball, so he chases the bird with a net and attempts to catch it. The bird continues with its song.

The comic is a play on the words 'bird' and 'song'. Birds, of course, don't actually sing: the sounds they make are territorial challenges, mating cries, etc. But in Western cultural traditions, particularly the pastoral one, imagining these sounds as 'song' is part of seeing nature as beautiful and harmonious. Ironically, the fact that this bird is really singing urban pop music, is perceived by Cueball to be an intrusion. Playing pastoral music to 'reprogram' the bird is of course an even more unnatural intervention - all with the purpose of restoring the pastoral naturalness of the morning.

The title text of "reprogramming" the bird by placing it in a box also refers to {{w|B. F. Skinner|B.F. Skinner}} and his development of {{w|Programmed learning|programmed learning}} through his theories of operant conditioning and behaviorism in psychology. By famously using birds in so-called Skinner boxes, he conditioned birds to respond expect certain stimuli for rewards and particular behaviors, leading to an understanding of many impulsive behaviors in humans like addiction. Cueball apparently hopes to "correct" the bird and its song through this method.

Several types of birds can mimic odd and unusual sounds, particularly the {{w|Lyrebird|lyrebid}} of Australia, known to reproduce all types of sounds from chainsaws, barking dogs, and certainly music.

==Transcript==
:[Cueball is walking through a field. Overhead, a bird is chirping.]
:Cueball: The sun is shining, the birds are singing—

:Bird [singing]: Got the kind of lovin' that can be so smooth, yeah

:Bird [singing]: Give me your heart, make it real

:[Cueball is chasing the bird with a butterfly net, the bird is flying away from Cueball, continuing to sing.]
:Bird [singing]: Or else forget about it

The name EE201 (Electrical Engineering 201) follows US course naming conventions for what appears to be a basic level course in electrical engineering (compare the term {{w|101 (term)|101}}), which would include being taught how to [http://www.wikihow.com/Calculate-Series-and-Parallel-Resistance calculate the effective resistance of various resistor networks]. Performing the calculation on a network this complex would probably be extremely difficult. It appears to work out to 0.75800964845 ohms.}}

If this were a real ECG trace, the absence of large, clear {{w|P wave (electrocardiography)|P waves}} might indicate {{w|Atrial Fibrillation|fine atrial fibrillation}}, but in some recording configurations, P waves are sometimes lost in the noise anyway. Additionally, without a time scale to tell us the ventricular heart rate, it is impossible to make a strong educated diagnosis of any hypothetical disease at all. If we assume it is atrial fibrillation, is not clear if Randall intended this, or if he is just not familiar with how a normal ECG should look.}}

Likely another improper unit - a reference to boolean values YES (TRUE) and NO (FALSE). Depending on the limits of a circuit, a resistor would still have a YES boolean value. Possibly indicating that this is a real resistor, as opposed to the one above it in the circuit, labeled "not a resistor."}}

Apparently the wire is or must be physically bent into a zig-zag shape, which would not serve much useful purpose, or perhaps it reflects the fact that any wire has a certain (small) amount of resistance just by being a wire.}}
