:: While this copy-cattism might be the reason for the proliferation of 420s (which, in India, is slang that, funnily enough, refers to a confidence-trickster) - note that at the beginning of the contest, a lot of different domain names all had 'scores' between 400-500. Now, if I'm not wrong, the hash contains 1024 bits. So you could be off by 1024 in the worst case, and 0 in the best case. But the spread was very narrow. Admittedly, you wouldn't notice the higher numbers, because only the best case scenario has been published, but from the clustering of the different universities (with respect to their scores), as well as the fact that it's taking this long for even ONE clear best score to emerge, seems to suggest that there IS something special about the 400-500 score band. Does anyone have any layman-level information on the statistics of the entropy of the Skein hash function? And the statistics of what error figure for random hash compared to given hash is most frequent? [[Special:Contributions/220.224.246.97|220.224.246.97]] 18:26, 2 April 2013 (UTC)

:::a hash is, at best, very close to a random number. Here, we have two 1024-bit random numbers. It makes sense that most commonly, two such random numbers differ in about half of the bits - for each bit, there's a 50% probability that the bits will be the same and 50% that they will differ. Therefore the spread centers on 512, but of course we just see the lower part of the spread here. [[Special:Contributions/2.223.68.79|2.223.68.79]] 23:46, 2 April 2013 (UTC)

:: My test here shows that the 420s is that 420 Bits wrong is about what a single computer can get to within a few hours. So its no wonder that 420s are common for a lot of universities. Its just someone there who is running a little script to break the hash.

::: Although it's true that if you run a PC for a couple of hours, you're very likely ending up somewhere between 415 and 425, this does not explain such a peak at 420. If you consider the probability function for a PC's best result within a day, then maybe 420 is the most likely outcome, but you should see a lot of 421s, 419s, 418s and so on: Seeing a number in 419...415 before you see a 420 should have a chance > 0.5.

The opening line of the first panel has changed. It's now "Ahoy, Carnegie Melonites!" (for the current school) rather than "Hey, [university] students!" (as listed in all the current entries for the changing first panel text). The question and response seem to be the same as before.

Someone, please explain what hash breaking is. [[User:Jackdavinci|Jackdavinci]] ([[User talk:Jackdavinci|talk]]) 04:00, 2 April 2013 (UTC)

:A cryptographically-secure hash function maps a set of numbers onto another set of numbers in such a way that converting forwards is easy, but converting back is difficult. The idea is that given a key and a lock, you can check the key against the lock by hashing the key and seeing if it maps to the lock. But given just the lock, you can't generate the key (easily). Randall gave us a lock, and the competition is to find the closest key. This is basically a competition to see who has the most computing power to generate lots and lots of keys. Keep in mind, I've glossed over a lot of technical details here. --[[Special:Contributions/173.162.57.51|173.162.57.51]] 15:22, 2 April 2013 (UTC)

:: There should be some cleverness involved in addition to access to computers. It all comes down to who can generate the most hashes in the time available, because as a good cryptographic hash Skein gives you no hint about how to change your input to get a result closer to your target, you just have to keep making guesses. But that is not just a matter of how many computers you have. For example, Googling around for implementations of Skein I didn't find any ready to run libraries for GPUs of Skein 1024 1024. A team at a university could have stuck with an existing C implementation running on an available set of computers, or taken the time to get it running on GPUs and get quite a bit of extra speed. Also, I haven't experimented with it, but a hash function should be faster if you give it a smaller input. The current best result from CMU would take on the average about 1 quadtrillion (1e15) trials to find. Given that the input to the hash has to be in the form of URL-safe printable characters, if you assume that your team will not have time to generate more than, say 1e16 hashes and the character set you have to work with is 100 characters (my guess from looking at my keyboard) then your test input strings do not have to be longer than 8 characters. Anyone who is generating test input for the hash that is any longer, for example if they are, as a really bad example, converting 1024-bit numbers to 256 ASCII character hex, is doing at least 32 times too much work for each hash calculation. [[User:Bugstomper|Bugstomper]] ([[User talk:Bugstomper|talk]]) 00:37, 3 April 2013 (UTC)
:The time it takes to compute a Skein hash depends only on the number of bits of internal state, not of the input.

With public key systems like PGP you need the public key of the other person to verify the authenticity of the message. Most people do not use PGP or do not know how it works or are just lazy. Some of those are convinced enough just by the outer looks of a signed email: The starting block and the jumbled chars at the end. It is like being impressed by a signature per se in real life without knowing what the one of the person you write to looks like. I think the allusion to pretty good is coincidental.

:Email client is supposed to automatically check the signature and report it's validity in a way which can't be counterfeited. Few if any do. On the other hand, how much do you really want to need the email is signed? Unless it's asking for password or something, which would be suspicious anyway ... (and in that case, you should reply by ENCRYPTED email. By definition, email encrypted with public key of someone you trust posted to attacker should be useless to him).

There is an interesting comparison to do with regular handwritten signature, as this is exactly how people check the authenticity of a handwritten signed document: check for a signature. If there is one, and if there is, even if you never saw a sample of that signature, trust it. However, as with cryptographic signature with an unknown key, this does rely one something: the fact that it is forbidden, and punishable, to counterfeit one's signature, even if it is badly done (as in: write a random signature, hoping that the recipient does not know the real signature of the alleged author). -- [[User:Elessar|Elessar]] ([[User talk:Elessar|talk]]) 09:02, 4 March 2013 (UTC)

I agree with the commenters above me and I think the explanation goes into the wrong direction. This cartoon has nothing to do with encryption, it's only about (cryptographically) signing an e-mail. PGP can do both, but whilst signing is done using your own secret PGP key, for encryption you must have the public key of the recipient, so they must already know how to use PGP (or GnuPG) and have it installed. The cartoon is about people who either do not have PGP installed in their e-mail program or are using a web mailer (like many) that cannot handle cryptographically signed messages. For them, the signature is useless, unless they believe that the mere existence of a signature is a proof that the message is authentic.
Oh, and the explanation is wrong on the ASCII armor. If you read the RFC correctly, this separation line is used if you ''don't have'' ASCII armored text but plaintext. [[Special:Contributions/128.7.3.55|128.7.3.55]] 09:40, 4 March 2013 (UTC)

This separation line signals that signature will be at the end, and that the mail will not be encoded in PGP-MIME, which pretty much requires that the signature is ASCII armored.[[Special:Contributions/195.144.91.202|195.144.91.202]] 12:03, 4 March 2013 (UTC)

:I also agree that the explanation doesn't really explain the point. PGP does not only provide encryption (which is in some sense privacy), but also authentication. If I publish my public key, anyone can use it to verify an email I signed with my private key. The joke is about what really happens. The text says: "If you find a header, this indicates a signed message. You are pretty safe if you assume the mail is authentic." This is funny, because email signatures are still so uncommon that there actually is no need to fake it. If you fake an email, why faking a signature? Just don't sign it. The image text goes one step further saying that you're safer when you look at the bottom of the mail and look for some weird random characters. This is what the actual signature looks like, but of course, the only way to really authenticate the mail is to use the sender's public key to verify that the random characters are a real signature. --[[User:BKA|BKA]] ([[User talk:BKA|talk]]) 12:19, 4 March 2013 (UTC)

I am not a native speaker, but after some research, I found that rubber/glue refers to the rhyme "I am rubber, you are glue, whatever you say bounces off of me and sticks to you." If that's true, the current explanation that the topos is meant "to imply that insults of another person are an indication of their own insecurity and weakness" is just plain wrong.

There's a typo in the comic - hte should be eht for "the" spelled backwards -jars99

Acutally, unicode 202e doesn't "flip proceeding text back-to-front", it overrides the direction, setting it to "right-to-left" for the following text. It's back-to-front for most of us like "left-to-right" is to other writing systems. I know it's nitpicking, but xkcd readers should appreciate the symmetry.

*It's a mistake to think the every-pickier level of detail is a flaw in these interest subcultures. Smaller and smaller levels of study are what flesh out our knowledge of the world. And myriad small subgroups of shared interests allow many people to achieve excellence and status, not just in their minds but in an (admittedly small) range of reality. Examples: the people who maintain and improve the Kennedy line of Boston Terriers; people whose specialty is tooth wear in prehuman hominids; people who parse xkcd comics.

* I don't think that the comic means it as a flaw, I think it's a just a (humourous) observation, not a negative critisism.

* Agreed, and it even goes on here (just drop in on the community portal, to see tempests in a tea pot such as whether he's [[Cueball]] or [[Rob]]...)

1093: Forget

2012-08-14T06:51:41Z

BKA: /* Explanation */

{{comic
| number = 1093
| date = August 10, 2012
| title = Forget
| image = forget.png
| titletext = 'Baby Got Back' turned 20 this year. My favorite nostalgia show is VH1's 'I Love The Inexorable March of Time Toward the Grave That Awaits Us All.'
| imagesize =
}}

==Explanation==
The median age in {{w|USA}} is currently about 37 years. Assuming that you must be at least five years old to remember a cultural event later, this means that anything that happened longer ago than the fifth birthday of someone who is 37 years now is remembered by a minority of people today. This applies to any event prior to 1980, so here in 2012, the majority of Americans are too young to remember the Seventies. However, according to census estimation the median will raise in the future, so instead of a 32 years gap between event and the moment when most people can't remember it, the gap becomes 35 years (implying a median of some 40 years).

'''2013: The Carter presidency''' {{w|Jimmy Carter}} was the {{w|President of the United States}} from 1977-1981. He lost all popularity after he controversially boycotted the {{w|1980 Olympics}}, in {{w|Moscow}} (at which time the {{w|United States}} and {{w|USSR}} were in the bitter arms race of the {{w|Cold War}}).

'''2014: The Reagan shooting''' References the 1981 {{w|Reagan assassination attempt|assassination attempt}} on the then American president, {{w|Ronald Reagan}}.

'''2015: The Falkand Islands War''' This is in reference to the {{w|Falklands War|brief outbreak of hostilities}} between the {{w|UK}} and {{w|Argentina}} over a small patch of rock off the shore of Argentina claimed by both but controlled by the UK. Even to this date, tensions remain high over the ownership of these islands, and while a majority of people alive weren't alive to remember it ''first hand'', it nevertheless remains present in the collective psyche of both nations.

'''2017: The first Apple Macintosh''' The {{w|Macintosh}} was a line of computers created by {{w|Apple Inc.|Apple}}, first introduced in 1984, with the introduction of the {{w|Macintosh 128K}}.

'''2018: New Coke''' References a public relations blunder that the Coca Cola corporation undertook in attempting to reformulate its cola recipe, the new formula called {{w|New Coke}} popularly. The public backlash so shook the company that they reintroduced the original recipe as {{w|Coca-Cola Classic}} within 3 months. New Coke was eventually rebranded from Coca-Cola to Coke II, and then discontinued. Coca-Cola Classic has quietly been rebranded back to simply Coca-Cola, as it originally was. The "New Coke" introduction is considered one of the biggest PR blunders from a major company ever.

'''2019: Challenger''' The {{w|Space Shuttle Challenger|Challenger}} was a {{w|NASA}} space shuttle, which was launched in 1986, but {{w|Space Shuttle Challenger disaster|exploded}} 72 seconds into its flight, killing everyone aboard, including {{w|Christa McAuliffe}}, a teacher selected to be the first teacher in space.

'''2020: Chernobyl''' Refers to the 1986 meltdown of a {{w|Chernobyl|nuclear power plant}} in the {{w|Ukranian SSR}} (then a part of the Soviet Union). The meltdown forced the nearby city of {{w|Pripyat}} to be abandoned, and it remains a ghost town today.

'''2021: Black Monday''' Refers to the 1987 {{w|Black_Monday_(1987)|day}} of the largest one-day {{w|stock market}} drop in history.

'''2022: The Reagan presidency''' {{w|Ronald Reagan}} was an American president from 1981 to 1989, and was a generally well received president known for ending the Cold War, oversaw the {{w|Iran–Contra affair}}, {{w|Invasion of Grenada|invading Grenada}}, and issuing forth a number of new {{w|Reaganomics|economic policies}}.

'''2023: The Berlin Wall''' Refers to the {{w|Berlin Wall|barrier}} surrounding the western-controlled part of {{w|Berlin}}. It was erected by the {{w|East Germany|East German}} Government in 1961 to stop illegal emigration to West Berlin---the western-controlled enclave after the ending of the second WW. After a friendly revolution in 1989, emigration to West Berlin (and West German in general) was granted suddenly and very surprisingly again on November 9, 1989. The following rush of people to the Wall from East (to cross the border) and from West (to welcome friends and relatives) in that night coined the figurative "Fall of the Wall", preceding the actual reunion of Germany in 1990 and (almost) complete demolition of the Wall.

'''2024: HammerTime''' Refers to a refrain in {{w|MC Hammer|MC Hammer's}} 1990 hit song {{w|U Can't Touch This}}; [[Randall Munroe]] makes reference to this song elsewhere in his comics, too (specifically {{explain|108}} and {{explain|210}}).

'''2025: The Soviet Union''' Refers to the cold-war adversary of the United States, emerging after the end of {{w|World War I}} and only collapsing in 1991.

'''2030: OJ Simpson's Trial''' The {{w|O. J. Simpson murder case|O.J. Simpson trial}} was a famous criminal case during which {{w|O.J. Simpson}}, a professional football player, was {{w|acquitted}} of the murder of {{w|Nicole Simpson}} and {{w|Ronald Goldman}}. He was later arrested and jailed for other crimes, including armed robbery and kidnapping.

'''2031: Clinton's reelection''' {{w|Bill Clinton}} was the American president from 1993 to 2001. He won his second term in the {{w|United_States_presidential_election,_1996|1996 presidential election}}.

Assuming that you must be at least five years old to remember a cultural event later, this means that anything that happened longer ago than the fifth birthday of someone who is 37 years now is remembered by a minority of people today. This applies to any event prior to 1980, so here in 2012, the majority of Americans are too young to remember the Seventies. However, according to census estimation the median will raise in the future, so instead of a 32 years gap between event and the moment when most people can't remember it, the gap becomes 35 years (implying a median of some 40 years).

'''2013: The Carter presidency''' {{w|Jimmy Carter}} was the {{w|President of the United States}} from 1977-1981. He lost all popularity after he controversially boycotted the {{w|1980 Olympics}}, in {{w|Moscow}} (at which time the {{w|United States}} and {{w|USSR}} were in the bitter arms race of the {{w|Cold War}}).

When Coca-Cola change the formula to New Coke, they kept the name "Coca-Cola" for the reformulated beverage, and discontinued the old formula. Because of the backlash, they reintroduced the old formula as "Coca-Cola Classic" and kept the new formula as "Coca-Cola". After a while, with "Coca-Cola Classic" being by far the biggest seller, the new formula was rebranded "Coke II", and eventually discontinued (I believe). The can I have in front of me is marked simply "Coca-Cola", so I guess "Coca-Cola Classic" was eventually rebranded back to the original name. --[[User:Blaisepascal|Blaise Pascal]] ([[User talk:Blaisepascal|talk]]) 17:55, 10 August 2012 (UTC)

Am I the only one who thinks that there are some other things needing explaining here? I have no idea what "Forgot About Dre" or "Baby Got Back" are about. (Well, not without a little googling.) And Pluto still exists, even if it's not currently classified as a planet (last I heard, they were considering classifying it and Charon as a twin planet system) so people are unlikely to forget about the name.--[[User:Joe Green|Joe Green]] ([[User talk:Joe Green|talk]]) 07:26, 11 August 2012 (UTC)

Oh and if Chernobyl is considered worthy of explanation, surely so is Challenger? Columbine too. Jeff's initial selection seems a little arbitrary, and while he justifiably never claims to provide a comprehensive explanation, we usually fill in the gaps.--[[User:Joe Green|Joe Green]] ([[User talk:Joe Green|talk]]) 07:34, 11 August 2012 (UTC)

:Gaps: Filled. By the way, none of the explanation was actually Jeff's. It's the collaboration of multiple users (feel free to pitch in).

The Berlin Wall was constructed by East Germany, not the USSR and it preceded the reunification of Germany. I've sort of fixed it, but it could do with more work. [[User:Jeremyp|Jeremyp]] ([[User talk:Jeremyp|talk]]) 10:35, 13 August 2012 (UTC)
: Good. I was just writing a comment about exactly these two points. Although the role of the soviets is not entirely clear, it was the Eastern German (aka German Democratic Republic) Government that decided and (mostly) Eastern German soldiers who built the Wall. And while the "Fall of the Wall" usually refers to the day where suddenly after a very confusing press conference, people could cross the border from east to west, the November 9, 1989, the reunification was a political and formal act in 1990, almost a year later. [[Special:Contributions/178.15.226.170|178.15.226.170]] 10:51, 13 August 2012 (UTC)
: Also, the wall was technically not torn down by anyone and especially not from both sides. After a series of weekly demonstrations in Eastern Germany (by a lot of courageous people in different cities), the Government made a decision to lift the travel restrictions, effectively allowing travelling to the West. On November 9, 1989, they made this official in a press conference which did not even receive a lot of attention at first. In this conference, someone raised the question when these new regulation would take effect, and seemingly unprepared, the speaker said "as far as I can see, it's effective immediately". Although there were so many people up that night in both East and West, and although maybe the mass of people prevented a shooting by the unprepared soldiers at the checkpoint, the revolution was not a spontaneous tearing of the wall, it was the demonstrations in the preceeding weeks by the Eastern German People. [[Special:Contributions/178.15.226.170|178.15.226.170]] 11:30, 13 August 2012 (UTC)

It seems whoever wrote the explanation for 9/11 has already forgotten the other two planes that crashed that day: one into the Pentagon, and one in a field outside of Shanksville, PA (Presumably on its way to crashing into the Capitol Building)

Actually I found the most crucial part, the math, was done poorly: Why do we have a 32 years gap today and a 35 years gap in the future, when the current median age is "around 35"?. I fixed it, but I'm not a native speaker, so I'd be happy if someone could go over the first paragraph (again). [[User:BKA|BKA]] ([[User talk:BKA|talk]]) 13:40, 13 August 2012 (UTC)
