3170: Service Outage

2025-12-10T19:22:13Z

Tooth: Added clarification about Wookiepedia.

{{comic

}}

==Explanation==
{{incomplete|This page was created BY SOMEONE WHOSE WORK RELIES ON THIS WIKI. Don't remove this notice too soon.}}
This comic compares the effects that different internet service outages can have on people's {{w|productivity}}. When the service is essential to someone's work, their productivity will clearly go down. They may initially be able to switch to alternative tasks, but the longer the outage goes on, the more of their task stack will be blocked and the less they will be able to accomplish. However, if the service (such as the {{w|Star Wars Legends}} wiki) is non-essential, their productivity improves, implying that without access to the service they are less distracted and get more work done.

The title text makes a distinction between the productivity effects of the {{w|Canon (fiction)|canon}} and non-canon {{w|Star Wars}} wikis. (In reality Wookieepedia, the main Star Wars wiki, covers both the Canon and Legends continuity.) A writer or editor for a forthcoming Star Wars product may have a work-related reason to review a wiki containing Star Wars canon, in order to ensure consistency with the work they are developing. Star Wars Legends, on the other hand, have been considered non-canon since 2014. While a fanfiction author {{tvtropes|FanonDiscontinuity|might have a reason to peruse information regarding the Legends continuity}}, there are vanishingly few people lucky enough that "writing fanfiction" can be considered "productivity" in any meaningful way. The character of [https://starwars.fandom.com/wiki/Natasi_Daala Admiral] [https://villains.fandom.com/wiki/Natasi_Daala Daala] is well documented, but a relatively niche line of interest.

This comic was posted the day after a major worldwide outage at {{w|Cloudflare}}, a major {{w|content delivery network}} (CDN) whose failure affected this very site (among many others). This outage followed outages a few weeks before at {{w|Microsoft Azure}} and {{w|Amazon Web Services}}, which provide {{w|cloud computing}} services, and fifteen months since {{w|2024 CrowdStrike-related IT outages|another significant outage}}. These aren't sites that most non-technical users are directly familiar with, but they provide infrastructure for many popular web sites, so their failures have wide-ranging impacts even for those who had been previously unaware of their role in their online life. For example, popular websites such as Netflix, Spotify, and Pinterest were affected by the AWS outage. The same day as the Cloudflare outage, there was also a {{w|Github}} outage; this site is used mainly to support software development.

2957: A Crossword Puzzle

2025-04-21T16:48:49Z

Tooth: Changed "An AAAA battery" to "A AAAA battery" because its pronounced "A quadruple A battery" not "An A-A-A-A battery." I mean right? Thats how I wrote it originally and someone changed it and I can't tell why, am I the weird one here?

{{comic
| number = 2957
| date = July 10, 2024
| title = A Crossword Puzzle
| image = a_crossword_puzzle_2x.png
| imagesize = 740x937px
| noexpand = true
| titletext = Hint: If you ever encounter this puzzle in a crossword app, just [term for someone with a competitive and high-achieving personality].
}}

==Explanation==
{{spoiler|The crossword clues comprise a single hidden joke, which you can figure out on your own. If you keep reading, you won't get the chance of discovering the joke yourself!}}
This crossword may seem extremely difficult, with questions covering a wide variety of trivia, linguistics, mathematics in various forms, alongside wordplay typical of crossword puzzles. But the joke is that every single letter of every single answer is "A". The name of this comic, "A Crossword Puzzle", is a {{w|double entendre}} which could, in itself, be considered a cryptic clue; the "A" can be interpreted both as the indefinite article "a" and as an identifier saying that this crossword puzzle is specifically an "A" puzzle, due to the answer being all "A"s.

The title text is a play on a "type A" personality. The term for someone with a competitive and high-achieving personality is "Type A". In the context of the title text, this answer is a hint that the entire puzzle can be completed in a crossword-solving app by typing the letter A repeatedly.

|-
| 15 || "CIPHERTEXT" decrypted with Vigenère key "CIPHERTEXT" || A "{{w|Vigenère Cipher}}" translates the original text by the distance from A from the key, letter by letter. For instance, if the plaintext is "XK" and the key is "CD", the C shifts X 2 forward to become Z, and the D shifts K 3 forward to become N, yielding a ciphertext of "ZN". Since the ciphertext and the key are the same in this case, decryption just shifts all the letters back to A, akin to subtracting a number from itself and getting 0. || 10

Following the example of the pattern in the clue, taking the first letter and every third one after (rather than just every third letter) we determine that '''A'''ph'''a'''nt'''a'''si'''a''' gives us the word "aaaa". This clue is particularly mean because of how it instructs you to visualize the letters highlighted within the word in order to get the answer. || 4
|-
| 19 || An {{w|acrostic}} hidden on the first page of the dictionary || The first page of the dictionary (if you ignore the copyright page and the index) is the list of words starting with A. An acrostic of this page, taking the first letter of each line and arranging them in order, would just be a sequence of As. || 15
|-
| 21 || Default paper size in Europe || {{w|A4 paper}} (here written as AAAA) is the default size in Europe. At 210×297 mm, it is approximately 0.24″ narrower and 0.71″ longer than the 8.5″×11″ paper used in the United States, and due to having an aspect ratio of 1:sqrt(2), can be cut or folded in half to create two half-sized sheets (A5) with exactly the same aspect ratio. A4 is, itself, also a halving of A3 and of identical ratio, as is the case with all A-sizes higher and lower in the sequence up to A0, which has an area of exactly 1 square meter.|| 4
|-
| 22 || First four unary strings || A unary number system represents numbers using just one symbol. For example, 7 in unary would be 1111111. The first four strings in unary, if you used A as the first (and only) symbol, would be A, AA, AAA, AAAA. || 10

|-
| 27 || A pair of small remote batteries, when inserted || Two {{w|AAA_battery|AAA}} batteries, which are often used to power remote controls for domestic devices. These have been combined to give AAAAAA — "Inserted" is often a cryptic hint that one word should surround another, although such a cryptic clue would normally also contain a more direct clue (albeit ambiguously) to the full answer. || 6
|-

| 2 || 1010101010101010101010102→16 || 10101010 10101010 10101010 in binary is equivalent to "AAAAAA" in hexadecimal. || 6

| 20 || Mario button presses to ascend Minas Tirith’s walls || In ''Mario'' games you typically use the A button to jump. In games where you don't press a button to move (e.g., games with a joystick), then the button presses required to ascend a vertical structure would probably all be A. This clue might have been inspired by the {{w|Pannenkoek2012#A-button challenge|A-Button Challenge}} / [https://ukikipedia.net/wiki/A_Button_Challenge A Button Challenge], which tallies the number of A presses needed to beat ''Super Mario 64''. Additionally, {{w|Minas Tirith}} is a fictional city in ''{{w|The Lord of the Rings}}'' with seven concentric rings, each with a wall around it and higher than the last ring. Presumably, it takes seven jumps to get to the highest area of the city, so the answer is "AAAAAAA". || 7

|-
| 28 || Unorthodox Tic-tac-toe win || {{w|Tic-tac-toe}} is usually won by getting either three Xs or three Os in a row, making XXX and OOO normal Tic-tac-toe wins. One could achieve a win of AAA by making the unorthodox choice of playing with the letter A instead of X or O. Alternatively, Randall is envisaging the grid as defined by rows 1, 2, 3, and columns A, B, C, so an AAA win would be simply playing in the first column each time - a strategy which should be obvious and easy to stop, even for young children who have not yet worked out that ''any'' route to winning can be blocked. || 3
|-
| 29 || String whose SHA-256 hash ends "…689510285e212385" || <code>printf AAAAAAAA <nowiki>|</nowiki> sha256sum</code> outputs <code>c34ab6abb7b2bb595bc25c3b388c872fd1d575819a8f55cc689510285e212385</code>.
Note that this 'clue' would be normally be ''particularly'' difficult, in isolation, as the nature of a {{w|hash function}} means that it is possible for multiple inputs to produce a given output, and that finding any of these (and definitely identifying ''all'' of them, to ensure you have the correct original) would require a {{w|brute-force attack}}; i.e. a test of all possible initial states to discover which of them might be viable candidates. Even more problematic is that we are only given a partial hash string, meaning we are possibly talking of a multiple of full hashes, each of them with a possible multiplicity of original plaintexts behind them. However, given the context of this puzzle, it's reasonable to guess that a sequence of 8 As might be the answer, and indeed its hash does match the clue given.
 The number of possible hashes in the clue is 1664/1616, i.e. 1648, or approximately 6x1054, although there really is no reason (aside from the fundamental impracticality) to try to solve this problem from each and every 'hash end'. Instead you would 'only' check every combination of 8 letters (presuming no digits, punctuation or whitespace would be inserted, that no "foreign"/accented characters are present and that uppercase is universally presumed, is 268; i.e. ~208 {{w|billion|short-scale billion}} possibilities) and discover which (one?) of these sufficiently matches the hash fragment given. Testing a hundred of these every second, it would take a little over 66 ''years'' to complete the task of checking every single possibility (rather than stopping at the first confirmed answer, which might well be the initial one in this particular case).
 In the context of a crossword such as this, however, you can significantly reduce this search by having established (or at least sufficiently narrowed down) the answers to the various across-clues which intersect with ever character of it (this form of crossword grid being of the {{w|Crossword#American-style crosswords|dense type}}, with no singly-clued spaces as with the more open lattice-types), reducing the necessary checks drastically. This could mean, having solved at least some of the perpendicular answers, that you have enough information to 'guess' at some likely answer, and then merely need to ''confirm'' that whatever guess(es) you make will resolve themselves into the clue-answer provided. (Much as you might with a more normally difficult clue, where you merely have to satisfy yourself that the surprise answer is at least justified as resulting from the original hint.)

**This was because one of the comics Randall lists as one of those he enjoys, [https://www.buttersafe.com/ Buttersafe], had already posted a similar comic back in 2011: [https://www.buttersafe.com/2011/02/17/crosswords/ Crosswords].
**Randall had forgotten this, but now pays tribute to this, stating that he must have been accidentally inspired by that comic.
*[[User:Elfakyn|Elfakyn]] posted a link to a picture of the solved crossword puzzle in the [[Talk:2957:_A_Crossword_Puzzle#Solved_puzzle_picture|comments]] and allowed it to be included here:
[[File:2957_A-Crossword_Puzzle-Solved.png|500px|center]]
*All the black squares are in a symmetrical pattern, which is generally the case for crossword puzzles in the US and UK. See description of the pattern in the [[#Transcript|transcript]].
*Crosswords have been mentioned previously in [[2896: Crossword Constructors]].
*Out of 60 clues in the puzzle, 10 are references to screaming or yelling, making the puzzle approximately 17% screams.

3079: Air Fact

2025-04-21T16:15:46Z

Tooth: /* Explanation */

{{comic
| number = 3079
| date = April 21, 2025
| title = Air Fact
| image = air_fact_2x.png
| imagesize = 250x394px
| noexpand = true
| titletext = 'Wow, that must be why you swallow so many of them per year!' 'No, that's spiders. You swallow WAY more ants.'
}}

==Explanation==
{{incomplete|This page was created by a MICROSCOPIC ANT and contains only microscopic text. Don't remove this notice too soon.}}
Microbiologist [[Megan]] tells [[Cueball]] that every cubic meter contains thousands of microscopic ants, which is not actually true.{{cn}} Initially incredulous, Cueball accepts this as a fact, because he doesn't have any easy way of take samples of air and putting them under a microscope.

There are indeed microorganisms floating in the air, and the joke is that microbiologists are tempted to make up things about them because most people can't verify them.

This comic could be referencing the problems with sampling bias when sampling air. Megan is extrapolating from a particularly bad sample. Presumable she sampled a 10 cubic centimeter space of air and found 1 ant in it. If she assumed that this was a representative sample, Megan could extrapolate this data to say that there are 10,000 ants for every 1 cubic meter (1,000,000 cubic centimeters). Randall Monroe has made other comics about dubious extrapolations: [[605]].

==Transcript==
:[Megan, with her palm out, is talking to Cueball.]
:Megan: Did you know that every cubic meter of air contains over 10,000 microscopic ants?
:Cueball: Wow, really?
:Cueball: I had no idea.

:[Caption below the panel:]
:The fact that taking air samples is hard presents microbiologists with a constant temptation.

Regarding the difficulty of sampling air. This seems to be another comic in the vein of [[605]]. Megan is extrapolating from a particularly bad sample. Presumable she sampled a 10 cubic centimeter space of air and found 1 ant in it. If she assumed that this was a representative sample, Megan could extrapolate this data to say that there are 10,000 ants for every 1 cubic meter (1,000,000 cubic centimeters).

3004: Wells

2024-10-28T15:43:17Z

Tooth: Nope nevermind someone already fixed it and I just made it worse.

{{comic
| number = 3004
| date = October 28, 2024
| title = Wells
| image = wells_2x.png
| imagesize = 306x402px
| noexpand = true
| titletext = You do have to be careful, though--sometimes, instead of water, you hit this free fuel that you can sell for a lot of money instead.
}}

==Explanation==
{{incomplete|Created by a WATERLOGGED OIL DRILL - Please change this comment when editing this page. Do NOT delete this tag too soon.}}
A water {{w|well}} is a hole dug in the ground, deep enough reach underground {{w|aquifers}}. They have been used for thousands of years as a source of water by people who don't live close to usable surface water sources like rivers and lakes.

This comic pokes fun of the seemingly improbable characteristics of wells. Talking about how water "randomly" forms below the surface of the ground and how they "magically" refill themselves. In reality there are complex systems (the {{w|water cycle}}) that dictate the formations of the underground pools that the wells take from and the underground rivers that refill them.

The title text points out that in some cases, people intending to drill water wells instead found oil beds. Oil is a very valuable energy source{{cn}}, so they became very wealthy as a result. This is the source of the idiom "struck oil" to mean receiving a windfall as a result of a lucky occurrence. But you have to be careful -- if you blindly "drink whatever you find at the bottom", as Megan says, you'll get very sick if it's oil rather than water.

:[Megan is on the left hand side and is facing Cueball who is on the right side and facing her. Megan has her left hand raised.]
:Megan: I need water, so I think I'll dig a deep hole and drink whatever liquid I find at the bottom.
:Cueball: What will you do after you drink it all? Dig another hole?
:Megan: I dunno. Hopefully it magically refills itself or something.

:[Caption below the panel:]
:It's ridiculous that wells work.
