Any bets on how many copies of this plaque people send him? [[User:Jordan Brown|Jordan Brown]] ([[User talk:Jordan Brown|talk]]) 00:25, 6 May 2023 (UTC)

I do not understand the plaque... If the test is correct, shouldn't there be an order button for not that expensive commemorative plaques on xkcd.com/2772? Questions over questions...[[User:Tier666|Tier666]] ([[User talk:Tier666|talk]]) 07:31, 6 May 2023 (UTC)
:By site, they mean "location". It was in that location when Randall figured out what is on the plaque. [[Special:Contributions/172.71.82.17|172.71.82.17]] 14:08, 7 May 2023 (UTC)Bumpf

Because it's vague, not worth an Explain expansion, but I'm wondering how much of the intervening week was delivery time of the original plaque (assuming the "lesson learnt" moment was the instant the original plaque was ordered, as it was too late on receipt to then ''make'' the claim of the achievement appear upon it). And it sounds like the plaquer had the bits handy (standard "202 different bits, screwdriver heads, sockets and related hardware"-type everyman-handyman accessory kit that you might get 'because why not?'/’it was marked as a deal!' on one visit to the hardware depot) but just had never (properly?) used the whole masonry set in anger, until now. And I don't discount the possibility that the second plaque was ordered to place over some initial ill-drilled holes from the first attempt at mounting (either done without regard to where further holes would need to align to the mortar bonds and courses, or an attempted to take advantage of that but badly), making the announcement of the second 'triumphant' occasion instrumental in legitimately masking the evidence of the learning process that led up to it.

I wonder if that's an oblique reference to the commemorative plaque Dieter Meier [https://en.wikipedia.org/wiki/Dieter_Meier#Artist had had installed at the Kassel railway station in 1972] that announced him standing there 22 years later?

In Denmark we celebrate the {{w|Denmark_in_World_War_II#Legacy|liberation from the Germans}} at the end of WW2 on [https://en.wikipedia.org/wiki/Denmark_in_World_War_II#/media/File:Danmarks_Befrielse,_Sdr_Hygum.jpg May 5th 1945]. And later also my birthday ;-) --[[User:Kynde|Kynde]] ([[User talk:Kynde|talk]]) 12:08, 6 May 2023 (UTC)

A bit of time paradox here. . . . . If he didn't figure out how to use a masonry drill until 12 May, then the top plaque couldn't have been installed before then. And the lower plaque would have been ordered, delivered and installed sometime after 12 May. Can we expect a third plaque commemmorating the mounting of the first and second? If so, when?

:No idea about the second, but I would assume that on 12 May, he ALSO installed the top plaque. -- [[User:Hkmaly|Hkmaly]] ([[User talk:Hkmaly|talk]]) 03:46, 7 May 2023 (UTC)
:5/5, figured out the plaques thing and ordered one (or sat on it, ordered a day or two later). ⩽12/5, received plaque and tried to install. 12/5, successfully installed, second plaque ordered (or possibly shortly after). >12/5, received and installed second plaque.

:Which makes this technically a science fiction comic, as it was released on 5/5. [[Special:Contributions/172.68.50.127|172.68.50.127]] 14:30, 7 May 2023 (UTC)

992: Mnemonics

2023-04-18T22:20:08Z

172.68.50.127: Misunderstanding in SI prefixes.

{{comic
| number = 992
| date = December 19, 2011
| title = Mnemonics
| image = mnemonics.png
| titletext = 'Sailor Moon's head exploded once' and 'Some men have explosive orgasms' both work for the Great Lakes from west to east (Paddle-to-the-Sea order).
}}

==Explanation==
A {{w|mnemonic}} is a trick that makes {{w|memory|memorization}} easier. To memorize a sequence of names, a common type of mnemonic uses the beginning letters of the names in the sequence and invents another phrase using different words that start with the same letters. For example, the order of operations goes '''P'''arentheses, '''E'''xponentiation, '''M'''ultiplication and '''D'''ivision, '''A'''ddition and '''S'''ubtraction, and the traditional mnemonic goes '''P'''lease '''E'''xcuse '''M'''y '''D'''ear '''A'''unt '''S'''ally, or in Britain: '''B'''rackets, '''I'''ndices, '''M'''ultiplication, '''D'''ivision, '''A'''ddition and '''S'''ubtraction: there is no mnemonic, just the word "BIMDAS" to remember. To make them more memorable, mnemonics are usually quite silly and often vulgar. In this comic, Randall invents various scientific mnemonics, some of them as suggested replacements for traditional ones.

The category is listed at the top of the box, the members are listed below that. Then there is the traditional mnemonic that children are usually taught in school to help them remember. Below the comic is one or two options for new mnemonics suggested by Randall. The top one is illustrated in the frame.

*{{w|SI}} Prefixes are the prefixes for the systems of units to indicate the orders of magnitude for the given value, and since there is one prefix set for large numbers, and another one for the small ones, the mnemonic needs two lines.
**{{w|Karl Marx}}, as visible in the comic, was a German philosopher and economist who, among other things, popularized the ideas of socialism and communism. Central to his ideas was the {{w|dictatorship of the proletariat}}, or the working class achieved by an uprising of the lower class, which taken literally could be done using zeppelins.
**{{w|Microsoft}}'s {{w|Zune}} was a failed mp3 player that Microsoft brought to market. It never caught on.

*{{w|Taxonomy}} is the science of identifying and naming species. {{w|Katy Perry}}, portrayed in the panel, is an {{w|United States|American}} {{w|pop music}} singer, whose popular songs are ones like "Firework" or "I Kissed A Girl".

*In the geologic periods frame, the illustration is of a month's worth of "the pill", a common contraceptive. The affliction Polycystic Ovarian Syndrome, causes women to have an irregular menstrual period. This can be treated with a low powered version of the contraceptive pill.

*{{w|Electronic_color_code#Resistors|Resistor Color Codes}} represent the values 0 through 9 and are used to indicate the resistance value of discrete cylindrical resistors, with 2 or 3 color bands around the resistor body for the significant digits of the value and another color band for a power of ten multiplier. A resistor with Yellow-Violet-Red bands would be 47 x 10^2 or 4700 ohms. {{w|Glenn Beck}} is shown in this panel, a far-right conservative commentator in the US who used to have a show on the {{w|Fox News}} Network.
**The prevailing mnemonic for resistor color codes is rather vulgar (and memorable), hence Randall's comment "none I care for". It involved Bad Boys and Young Girls, as well as a specific girl named Violet. However, there are many other mnemonics, to the point that Wikipedia has a {{w|List of electronic color code mnemonics|whole page dedicated to them}}.
**{{w|WP:BOLD|Be Bold}} is a {{w|Wikipedia}} credo. Respect Others may be a reference to {{w|WP:AGF|Assume Good Faith}}, another Wikipedia philosophy.

*In the Planets frame, the illustration is of Mary and Joseph, who in the story of the Birth of Jesus in the Bible, were mother and father to Jesus. However, Mary's conception of Jesus was from God and Mary was still considered a virgin. This mnemonic shows Joseph not really believing that story. Ironically the upstairs neighbour could have multiple meanings as you can't get more upstairs than heaven and thus God. Given the snarky tone of most xkcd comics take, it is likely a corporeal neighbor that is being suspected, but it is curious that a neighbor of the upstairs variety is specifically referenced especially given the lack of urban density in the time of Christ.
**Earlier traditional Planets mnemonics included Pluto, which was "officially" considered a planet before 2006. The traditional mnemonic at that time was '''M'''y '''V'''ery '''E'''xcellent '''M'''other '''J'''ust '''S'''erved '''U'''s '''N'''ine '''P'''izzas, instead of just nachos.

*The {{w|Great Lakes}} mentioned by the title text are Superior, Michigan, Huron, Erie, and Ontario
**''{{w|Sailor Moon}}'' is an anime and manga series. The eponymous {{w|Sailor Moon (character)|Sailor Moon}} (Usagi Tsukino), has never had her head exploded, however.
**''{{w|Paddle-to-the-Sea}}'' is an illustrated children's book by {{w|Holling C. Holling}} about a toy boat's journey through the Great Lakes.

948: AI

2023-04-10T15:01:40Z

172.68.50.127: /* Adding rocky deserts */

{{comic
| number = 948
| date = September 7, 2011
| title = AI
| image = ai.png
| titletext = And they both react poorly to showers.
}}

==Explanation==
This comic is a reference to the wildly funny{{Citation needed}} [http://www.youtube.com/watch?v=WnzlbyTZsQY video] of two {{w|Cleverbot}}s talking to each other. By recording and analyzing whatever humans type into its input, they can sound pretty human to whoever is reading their response.

[[Megan]] has been watching the video and asks [[Cueball]] about it. He says it's just "clumsy sampling" as they are still very far from sounding like humans and holding normal conversations.

Megan then sums up that as of the release of this comic computers were good at {{w|chess}} and at driving cars through a desert (Although some might think of deserts as a place with no obstacles to hit, one must also consider rocky deserts which are a rather difficult terrain to navigate: making this search field very interesting for space exploration as well. The ability of such {{w|self-driving cars}} would improve much later, with this comic being the first with a direct reference to such cars. Later self-driving cars became a [[:Category:Self-driving cars|recurring topic]] on xkcd). But they cannot hold a conversation for five minutes. And she thus concludes that a cleverbot would be perfect for attending ''Burning Man''.

{{w|Burning Man}} is a week-long event held yearly in Black Rock City, Nevada. The festival encourages an artistic, anti-establishment philosophy and attracts a broad but devoted following combining hippies, anarchists, nudists, techno-utopians and survivalists. [http://www.burningman.com/art_of_burningman/art_cars_on_the_playa.html Shows of custom cars on the desert plain] are a big part of Burning Man, and [http://www.flickr.com/photos/michicat/2865986618/ mental games like chess] are a popular way to pass the time there. However, a common joke about Burning Man attendees is that they can only talk about Burning Man - hence why they can't hold a five minute conversation.

A tradition of Burning Man is not to shower while you are there, mostly because [http://www.burningman.com/preparation/event_survival/water.html all water must be brought in from offsite.] And of course Cleverbot reacts badly in showers because if you do try to shower a Cleverbot, you end up with a shorted out computer.

==Transcript==
:[Megan sits on an office chair at a desk. A laptop computer is on the desk, audio from a Cleverbot chat is shown coming from the laptop with a zigzag line from the screen. Megan has turned her head away from the computer to the right addressing Cueball off-panel.]
:Megan: Did you see the Cleverbot-Cleverbot chat?
:Cleverbot (from computer): I am not a robot. I'm a unicorn.

:[In the next frame-less panel, Megan has turned the chair away from the desk, which is not shown, and is now sitting with her hands in her lap in front of Cueball who holds one hand up as he replies.]
:Cueball: Yeah. It's hilarious, but it's just clumsily sampling a huge database of lines people have typed. Chatterbots still have a long way to go.

:[A close-up of Megan's head and shoulders. She has a hand to her chin and appears to be contemplating the last remark. Cueball replies from off-panel.]
:Megan: So... Computers have mastered playing chess and driving cars across the desert, but can't hold five minutes of normal conversation?
:Cueball (off-panel): Pretty much.

:[Both are shown again as in panel two, Cueball with his hands down.]
:Megan: Is it just me, or have we created a Burning Man attendee?

==Trivia==
Randall's sarcastic comparison from AI systems to burning man atendees turned out to be more true than expected, as current AI systems were shown and proven to have a bias to align to their programmers's beliefs and political compass.
Which makes it now a major research area to make AI systems truly neutral in their interactions.
