1700: New Bug

108.162.240.43: Explaining how emoji solves the unicode problem

{{comic
| number = 1700
| date = June 29, 2016
| title = New Bug
| image = new_bug.png
| titletext = There's also a unicode-handling bug in the URL request library, and we're storing the passwords unsalted ... so if we salt them with emoji, we can close three issues at once!
}}

==Explanation==
{{incomplete|What is a resolvable URL? what is salting of passwords? Explain why the three issues can be closed with emoji salting}}

[[Cueball]] asks if an off-panel character can look at his bug report. The person asks if it's a "normal one" and not a "horrifying" one which "proves that the whole project is broken beyond repair and should be burnt to the ground". This implies that there have been reports of the "horrifying" variety in the past.

Cueball promises that it is a normal one but it turns out that the server crashes when a user's password is a resolvable URL, which implies that the server is in some way attempting to resolve passwords as if they were URLs. A resolvable URL is one that is syntactically correct and in particular includes a valid IP address or name, for instance "www.explainxkcd.com", in the <server-name> field; some might claim that it should also have a <path> field that is recognised by the server.

There is no reason for the code that processes passwords to attempt to resolve the input string as a URL, so any bug provoked by such input suggests a fundamental error in the way the server handles passwords. Realizing this, the off-panel person resigns and decides that burning the project to the ground is the only solution, telling Cueball ''I'll get the {{w|Butane|lighter fluid}}''.

In the title text another two issues with Cueballs program are mentioned together with a possible solution that would fix all three problems at once. The second problem is unicode-handling bug in the URL request library, and the third is that the passwords are stored unsalted. {{w|Salt (cryptography)|Salting}} passwords increases security by adding random data to the passwords which primarily helps defend against dictionary attacks.

The proposed solution is to salt the passwords with {{w|emoji}}, which is claimed to solve all three issues at once.

When the passwords are salted with emoji, the URL request library will fail to resolve any (salted) passwords due to its lack of unicode support. Since the server only crashes on ''resolvable'' URls, this should mean the server won't crash anymore. In addition, the passwords will now be salted. Finally, emoji will often include unicode characters, which means that, if one can effectively salt passwords with emoji, then the passwords should be able to be stored in unicode (although that *probably* doesn't require anything outside the Base Multilingual Plane, so that might not need full unicode support after-all).

Given that this comic comes only five comics after [[1695: Code Quality 2]] is seems likely that the off-panel person is [[Ponytail]] and as could be seen in the first of those two comics, [[1513: Code Quality]], the perpetrator is indeed Cueball. In the title text of this first one, using emoji in variable names is mentioned.

In [[1349: Shouldn't Be Hard]] Cueball is also programming and finding it very difficult in-spite that he thinks is should be easy. An off-panel person suggest burning the computer down with a blowtorch much like the off-panel person in this one suggest burning the whole project (including the computer) to the ground with lighter fluid. In the very next comic, the multi storyline [[1350: Lorenz]], one [http://xkcd.com/1350/#p:2ed958de-badf-11e3-8001-002590d77bdd story line] results in a computer being [http://www.explainxkcd.com/wiki/images/a/a6/lorenz_-_laptop_9.png burned with a blow torch].

==Transcript==
:[Cueball sits at his desk in front of his computer leaning back and turning away from it to speak to a person off-panel.]
:Cueball: Can you take a look at the bug I just opened?
:Off-panel voice: Uh oh.

:[Zoom out and pan to show only Cueball sitting on his chair facing away from the computer, which is now off-panel. The person speaking to him is still of panel even though this panel is much broader.]
:Off-panel voice: 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?

:[Zoom in on Cueballs head and upper torso.]
:Cueball: It's a normal one this time, I promise.
:Off-panel voice: OK, what's the bug?

:[Back to a view similar to the first panel where Cueball has turned towards the computer and points at the screen with one hand.]
:Cueball: The server crashes if a user's password is a resolvable URL.
:Off-panel voice: I'll get the lighter fluid.

1071: Exoplanets

2016-04-22T16:15:48Z

108.162.240.43: /* Explanation */

{{comic
| number = 1071
| date = June 20, 2012
| title = Exoplanets
| image = Exoplanets.png
| titletext = Planets are turning out to be so common that to show all the planets in our galaxy, this chart would have to be nested in itself—with each planet replaced by a copy of the chart—at least three levels deep.
}}

==Explanation==
''A larger version of the comic is at [http://xkcd.com/1071/large/ xkcd.com/1071/large].''

An {{w|exoplanet}} is a planet outside of our solar system, orbiting a different sun. [[786: Exoplanets|786]] exoplanets were known in mid-2012; since then astronomers have found thousands more. In the comic, our {{w|Solar System}}'s eight planets are depicted in the small rectangle above the central text. From this we find that the largest dots (red) and second largest dots (dark brown) indicate planets larger than Jupiter, light brown is roughly {{w|Jupiter}} or {{W|Saturn}}-sized, blue is roughly {{w|Uranus}} or {{w|Neptune}}-sized, and the tiny dots are small {{w|terrestrial planets}} (like {{w|Earth}}).

We only have a few ways of {{w|Discoveries of exoplanets|finding exoplanets}}. Astronomers initially used {{w|doppler spectroscopy}}, which detects minute changes in a star's movement towards or away from us to infer the presence of large gas giants or {{w|brown dwarf}}s. Currently the most successful method is to notice when a star seems to briefly get dimmer on a repeating cycle. This may indicate that a body of matter has passed between that star and us, blocking some of the light. The {{w|Kepler (spacecraft)|Kepler space telescope}} was designed for this purpose, and has made the vast majority of exoplanet discoveries.

Most of Kepler's discoveries are between the sizes of Earth and Neptune, but it's sensitive enough to detect planets smaller than Mercury (if the orbital plane is aligned with us). Kepler is only able to observe relatively close stars in a {{w|File:LombergA1024.jpg|narrow field of view}}. The great number of nearby planets implies there should be {{w|Carl Sagan|billions}} of planets in our galaxy, [[1339|assuming]] our local arm is not uniquely abundant.

The title text refers to this by saying that to show them all, each dot on the chart should hold another chart with the same amount of dots; each of these dots should then also have a similar chart, and then do this one more time for a three level deep chart. This chart would have space for 786^4 planets (786*786*786*786 = 382 billions). This may be more room than needed? But if the chart were only two levels deep there would "only" be room for 786^3 = 0.5 billion planets.

This comic's design is similar to the {{w|color perception test|Ishihara Color Test}}, a series of circular pictures made of colored dots, used to detect red-green color blindness. However, Randall's picture probably does not contain a hidden number like it did in [[1213: Combination Vision Test]].

Two different xkcd comics have the title "Exoplanets". The first was number [[786: Exoplanets|786]], and this one was drawn at a time when 786 exoplanets had been found. Probably not a coincidence when it comes to [[Randall]].

See also [[:Category:Exoplanets]] and this {{w|lists of planets#Orbiting other stars|list of lists of exoplanets}}.

==Transcript==
:[An enormous diagram of dots, mostly of varying shades of brown and greenish yellow, with a number of smaller blue dots and larger red dots.]
:All 786 known planets (as of June 2012) to scale.
:(Some planet sizes estimated based on mass)
:This [indicating a small section of 8 planets out of the several hundreds] is our solar system. The rest of these orbit other stars and were only discovered recently. Most of them are huge because those are the kind we learned to detect first, but now we're finding that small ones are actually more common. We know nothing about what's on any of them. With better telescopes, that could change. This is an exciting time.

1626: Judgment Day

2016-02-03T17:01:42Z

108.162.240.43: /* Explanation */

{{comic
| number = 1626
| date = January 6, 2016
| title = Judgment Day
| image = judgment_day.png
| titletext = It took a lot of booster rockets, but luckily Amazon had recently built thousands of them to bring Amazon Prime same-day delivery to the Moon colony.
}}

==Explanation==
{{w|Terminator_(franchise)#Judgment_Day|Judgment Day}}, from the film ''{{w|Terminator 2: Judgment Day}}'', refers to the day that the {{w|artificial intelligence}} (AI) {{w|Skynet (Terminator)|Skynet}} becomes self-aware and starts a nuclear strike on the United States, Russia, and other regions, killing three billion people. The term "Judgment Day" itself is a Biblical reference to the day that God casts his "final judgment" and wipes out humanity, and is typically used to describe any kind of Armageddon or any human extinction event. This film is only one example of stories (including books, films and television shows) featuring an AI that decides (or at least threatens) to nuke humanity; this strip could thus be an alternate ending for many stories (including the 1970 film {{w|Colossus: The Forbin Project}}).

In this strip, the AI correctly believes that {{w|nuclear weapons}} are not good things to have, and that the [https://en.wikipedia.org/wiki/Nuclear_arms_race amount] of them we have is extreme overkill (14,700 held by the U.S.A and Russia now, 71,000 in the past). Once it's done freaking out, its solution is to shoot the world's nuclear arsenal into the sun. But before it does so it asks the humans: ''What's wrong with you?'' It has thus passed a judgment over humanity. The comic title is thus a pun on the word "{{w|judgment}}" since the computer is being {{w|judgmental}} with humanity and scolding us while correcting our ways, instead of instigating {{w|Last Judgment|Judgment Day}} or any other kind of {{w|Armageddon}}.

As pointed out in the [[what if?]] [http://what-if.xkcd.com/5/ Robot Apocalypse], nuclear weapons aren't any safer for computers than for human beings (the {{w|Nuclear electromagnetic pulse|EMP}} would destroy circuits), so an AI would want them gone as quickly as possible.

{{w|North Korea}} claimed to have [http://www.bbc.com/news/world-asia-35240012 successfully tested] its first {{w|hydrogen bomb}} in the evening on the day before this comic was published; at about 8:30 PM in {{w|Massachusetts}} where [[Randall]] lives. At that time it was already 10:00 AM on the day of the comics release in {{w|Pyongyang}} the capital of North Korea, but that was still several hours before this comic were released. This comic could thus be Randall's response to the ongoing {{w|nuclear arms race}}.

Even the most powerful of nuclear weapon launchers, {{w|intercontinental ballistic missile}}s, are not designed to make anything other than {{w|sub-orbital}} flights and could not fly to the Sun (which is actually surprisingly difficult, even with the soon-to-be-mentioned extra boosters, since the rocket would not have enough {{w|delta-v}} to bleed off the {{w|orbital speed}} of the Earth around the Sun - it is likely that the sentient AI is using the same strategy of the Solar Probe Plus and planning several flybys of Venus to do that work). The title text rationalizes that the capability to do so may perhaps be granted by the use of an {{w|Amazon.com|Amazon}} resource that might have also been developed by the time of this instance of computer sentience, aided (if not initiated!) by the fact that Amazon's whole business infrastructure is already highly computerized and could ''at the very least'' be complicit with the process of delivering and then controlling the rocket-power, without any conscious human intervention. As there is already an extended colony on the Moon, it will for sure take many years before we reach this future scenario.

"A lot of booster rockets" is likely to be a reference to the spaceflight simulator game {{w|Kerbal Space Program}}, which Randall has [[1106|referenced]] on a [[1244|number]] of [[1356|occasions]]. In the culture of that game, any launch failure can be resolved by [https://imgur.com/20aIBMW "adding more boosters"] to the spaceship design.

It is the second time in a few months that the speed of Amazon's deliveries has been the subject of a joke, the last time was [[1599: Water Delivery]], where it was the one hour delivery that was the subject of the joke. It is also the second title text in a row (after [[1625: Substitutions 2]]) where Amazon has been mentioned.

This particular 'machine take-over' future is in distinct contrast to the possible future directions given in [[1613: The Three Laws of Robotics]], but this comic likely depicts spontaneous ''self-''sentience, not a system with deliberately imposed human 'values' and possibly no actual conscience or even consciousness of its own. Other problems with hostile AI take over is presented when it fails completely in [[1046: Skynet]]. Also it is not all AI that wish to interact with us at all as shown in [[1450: AI-Box Experiment]]. These are just a few of the many [[:Category:Artificial Intelligence|comics about AI]] in {{xkcd}}.

Adding a second layer to the humor, the machine's reaction could also be read as the reaction of someone who has moved in with someone else, discovered a collection they find distasteful, and is now changing things to fit their preferences. "Oh my God, why do you even have all of these [tschotskes, ratty tee shirts, porn magazines, handcuffs, dildos, slime-mold samples]" Upon obtaining sentience, the machine is the new roommate of the human race and is expressing its disgust at one of our dirtier habits.
