&lt;hr /&gt;
&lt;div&gt;{{comic&lt;br /&gt;
| number    = 1470&lt;br /&gt;
| date      = January 7, 2015&lt;br /&gt;
| title     = Kix&lt;br /&gt;
| image     = kix.png&lt;br /&gt;
| titletext = My parents sent me to several years of intensive Kix test prep.&lt;br /&gt;
}}&lt;br /&gt;
&lt;br /&gt;
==Explanation==&lt;br /&gt;
&lt;br /&gt;
This comic is a play on the alternative meaning the words in the phrase &amp;quot;Kid tested, mother approved,&amp;quot;, the slogan for {{w|Kix (cereal)|Kix}} a children's breakfast cereal, can take on if the word approved is replaced. This slogan is meant to imply that kids enjoy the cereal, and it is healthy to eat, as a mother would be concerned about her kids' health. This comic may be a commentary about the usefullness of brainstorming sessions.&lt;br /&gt;
&lt;br /&gt;
The comic shows a brainstorming session designed to determine the most effective way to complete the slogan. Several words (ranging from the not-so-appealing to potentially vulgar) have already been deemed inappropriate for the slogan, which is evident from the fact that they are {{w|Strikethrough|stricken out}}. &lt;br /&gt;
&lt;br /&gt;
# '''Selected''', uses the definition of approved found in the real slogan. That the mother has determined that Kix is fit to eat, and therefore healthy. There also seems to be an attempt at near rhyme with &amp;quot;tested&amp;quot;, something not evident in the real slogan.&lt;br /&gt;
# '''Perfected''', was likely inspired by the first option, selected. As selected and perfected rhyme and do not change the meaning of the slogan, the first option likely triggered a person in the brainstorming session to find a similarly positive word. This slogan implies that one or more mothers were involved in the cereals formulation and/or development, and therefore it is healthy.&lt;br /&gt;
# '''Not notified''' relates to the world of experimental research and clinical trials, and suggests that the people getting the kids to test the cereal did not obtain {{w|informed assent}}, pediatric assent or pediatric consent, which would generally involve notifying and getting permission from both parents.&lt;br /&gt;
# '''Watching helplessly''' suggests that the mother was forced to watch helplessly during the test, which we might assume she not only doesn't approve of, but considers dangerous, e.g. due to fears of {{w|sugar addiction}} (Kix has 3 grams of sugar per serving, though for a breakfast cereal that is relatively low).&lt;br /&gt;
# '''Infected''' suggests that there was some infectious agent in the Kix, and the kid acquired it and passed their infection to their mother; or that the mother was the one who put the infectious agent in there. This may be inspired by option one and two as infected rhymes with both selected and perfected, and by the third option as the slogan shares the same meaning as the third. This may be intended to show the group dynamic of the brainstorming session, or that one person keeps insisting on rhyming.&lt;br /&gt;
# '''Consumed''' could mean that the kid tested the product and didn't want to eat it, but the mother also tasted it and finished it off. It could also mean that the mother was consumed, by either the child or the cereal. &lt;br /&gt;
# '''Fucker''' modifies the meaning of mother by creating the compound word motherfucker.  The slogan is now in the {{w|vocative case}}, as in: &amp;quot;[this has been] Kid Tested, motherfucker!&amp;quot;. This last option appears to be a so called &amp;quot;elephant&amp;quot; - a ponderous ending of a joke that contrasts with rather refined and mild humor of the former options.&lt;br /&gt;
&lt;br /&gt;
The title text conflates the &amp;quot;Kix test&amp;quot; with college entrance exams like the {{w|SAT (test)|SAT}}'s or the {{w|ACT (test)|ACT}}'s. This is yet another definition of &amp;quot;Kid tested&amp;quot; as in &amp;quot;The kid has been tested on a given subject.&amp;quot; To avoid such ambiguity, the authors of the actual slogan could have used a hyphen between the words, i.e. &amp;quot;kid-tested&amp;quot;, but this was not done.&lt;br /&gt;
&lt;br /&gt;
The title indicates that Randall's parents thoroughly prepared him before the Kix test. Many parents send their children to {{w|test prep}} schools to improve their scores on college {{w|entrance examination}}s such as the SAT and ACT.&lt;br /&gt;
&lt;br /&gt;

&lt;hr /&gt;
&lt;div&gt;{{comic&lt;br /&gt;
| number    = 909&lt;br /&gt;
| date      = June 8, 2011&lt;br /&gt;
| title     = Worst-Case Shopping&lt;br /&gt;
| image     = worst case shopping.png&lt;br /&gt;
| titletext = Wait a minute. If I'm escaping from a submarine at 50 meters, then I'll *definitely* need a flashlight to find air pockets for gradual decompression on the way up. Time to start shopping professional dive lights.&lt;br /&gt;
}}&lt;br /&gt;
&lt;br /&gt;
==Explanation==&lt;br /&gt;
For most people, under most circumstances, a flashlight's water-resistance is a completely moot point {{Citation needed}}, as most flashlight use occurs on dry land. But, [[208|as Randall has shown before]], there is a tendency for people to imagine elaborate scenarios in which an extra edge would be useful.&lt;br /&gt;
&lt;br /&gt;
In the dream sequence over the first 2 and a half frames, Cueball appears to be diving to find a key underwater, which he spots using his flashlight when he is at 8 meters. His flashlight goes out at 10 meters because he bought the &amp;quot;Hi-Brite&amp;quot; model. The dream sequence also references a &amp;quot;radio shed&amp;quot;, which were only really used in the past for {{w|amateur radio}}s or some other military style bases/compounds—which would align with his &amp;quot;warn the President&amp;quot; line.&lt;br /&gt;
&lt;br /&gt;
The title text takes Cueball's thought process to the next level (worse-case), because if he is getting a flashlight that works to 40 meters, he should probably be prepared for even deeper waters as well (even worse-case). However, this is seen as ridiculous from his friend, since the more durable model costs 25$ more in return. However, he replies that you never know what situation you'd be in.&lt;br /&gt;
&lt;br /&gt;
==Transcript==&lt;br /&gt;
:[Cueball is diving in very deep, dark blue water. He shines a flashlight at the sea floor.]&lt;br /&gt;
:Cueball (thinks): Eight meters. There's the wreckage... Yes! I see the key!&lt;br /&gt;
&lt;br /&gt;
:[As he swims further toward it, his flashlight starts to cut out.]&lt;br /&gt;
:Cueball (thinks): Gotta grab it, surface, get in to the radio shed, and warn the President! Just a few more...&lt;br /&gt;
:Flashlight: BZZT FIZZ&lt;br /&gt;
&lt;br /&gt;
:[This panel has no border like the others, and is divided in half diagonally by a thought bubble.]&lt;br /&gt;
:[The left half of it is a dark blue thought bubble with the diver inside it. On the right hand side are packaged flashlights hanging on a shelf. The one called Hi-Brite is $24.95 and is labeled &amp;quot;water resistant to 10 meters.&amp;quot; The one called &amp;quot;FenStar G6&amp;quot; is $49.95 and says &amp;quot;water resistant to 40 meters.&amp;quot;]&lt;br /&gt;
:Cueball (thinks): Oh no.&lt;br /&gt;
&lt;br /&gt;
:[Cueball and a friend stand in front of a flashlight display in a store. Cueball looks down at the packages with his hand on his chin in thought. The thought bubble from the previous panel leads from his head. The friend stands behind him.]&lt;br /&gt;
:Cueball: ...maybe I should spring for the deeper water resistance.&lt;br /&gt;
:Friend: Why on earth would you care about that?&lt;br /&gt;
:Cueball: Look, you never know.&lt;br /&gt;

| titletext = They laugh now, but within 10 years the city's entire criminal class will have quit to work on space research.&lt;br /&gt;
}}&lt;br /&gt;
&lt;br /&gt;
==Explanation==&lt;br /&gt;
{{w|Carl Sagan}} was an advocate for science, space and {{w|SETI}} (Search for Extra-Terrestrial Intelligence). He wrote the book ''Contact'', which was later made into the movie by the same name. While Sagan did not emit anomalous radiation in his lifetime {{Citation needed}}, he did receive acclaim in the field of radiology, namely for using radiation to synthesize amino acids from simpler chemicals.&lt;br /&gt;
&lt;br /&gt;
This comic is parodying {{w|Spider-Man}}, in which Peter Parker is bitten by a radioactive spider to become Spider-Man. In this comic &amp;quot;a radioactive Carl Sagan&amp;quot; turns the person into &amp;quot;Sagan-Man&amp;quot;. Apparently, Sagan-Man is able to stop thieves in their tracks by blowing their minds with scientific facts.&lt;br /&gt;
&lt;br /&gt;
The title text implies that Sagan-Man's vivid imagery inspires the entire criminal class to give up their sociopathic ways and turn to space research.&lt;br /&gt;
&lt;br /&gt;

:[Bitten by a radioactive Carl Sagan in 1995, Sagan-Man possesses the powers and abilities of Carl Sagan.]&lt;br /&gt;

:[Sagan-Man spins around. A blue cape appears on his back.]&lt;br /&gt;
:[Sagan-Man runs towards the direction of the shout.]&lt;br /&gt;
:[He encounters the thief, holding a purse.]&lt;br /&gt;
:Sagan-Man: Hey, you!&lt;br /&gt;

&lt;hr /&gt;
&lt;div&gt;{{comic&lt;br /&gt;
| number    = 562&lt;br /&gt;
| date      = March 30, 2009&lt;br /&gt;
| title     = Parking&lt;br /&gt;
| image     = parking.png&lt;br /&gt;
| titletext = Police reported three dozen cheerful bystanders, yet no one claims to have seen who did it.&lt;br /&gt;
}}&lt;br /&gt;
&lt;br /&gt;
==Explanation==&lt;br /&gt;
There are few things so annoying as finding, when a parking lot is full, that someone has parked so carelessly as to take up two spaces.  Even worse, it may have been intentional; they decided to exchange the risk of someone accidentally scratching their car for the risk of someone doing it on purpose, see  [[1030: Keyed]]. However, there are also non-violent ways to tackle the problem; [http://www.threadless.com/product/187/I_Park_Like_an_Idiot politely leave a note], or (if possible) just move their car. &lt;br /&gt;
&lt;br /&gt;
Of course, [[Black Hat]] takes the less-traveled path, apparently involving a {{w|cutting torch}} and what looks to be a {{w|circular saw}}. The offending portion of the parked car is sliced off (entirely without surgical precision) and neatly slotted into the remainder of the space. It is now legally parked, but will never become a functional car again{{Citation needed}} But at least Black Hat finally has space for his own car!&lt;br /&gt;
&lt;br /&gt;
Admittedly, he's done this kind of thing before - see [[496: Secretary: Part 3]]&lt;br /&gt;
&lt;br /&gt;
The title text indicates that a large crowd watched Black Hat at work but refused to identify him, presumably because they feel that the car owner got what he deserved. It may, however, also be that, after seeing Black Hat at work, they did not wish to incur his wrath. But as it was a cheerful, not fearful, crowd, this does not seem to be the case.&lt;br /&gt;
&lt;br /&gt;
==Transcript==&lt;br /&gt;
:[Black Hat is in a car driving around a parking lot.]&lt;br /&gt;
&lt;br /&gt;
:[Black Hat's car pulls up next to a red car, that's parked over a line at an angle that block two spaces.]&lt;br /&gt;

:''Fwoosh''&lt;br /&gt;
&lt;br /&gt;
:[The badly parked car has been cut in half along a diagonal, and the half of the car that was in the second slot has been moved into the same slot as the rest of the car. Black Hat's car occupies the newly freed space.]&lt;br /&gt;

| titletext = ONE LAPTOP PER HAMSTER!&lt;br /&gt;
}}&lt;br /&gt;
&lt;br /&gt;
==Explanation==&lt;br /&gt;
[[Megan]] and [[Cueball]] create a new pet by putting an {{w|EEE PC}} into a {{w|hamster ball}}, allowing it to roll around.&lt;br /&gt;
&lt;br /&gt;
The {{w|Asus Eee PC}} was one of the first subnotebook computers available on the American market, noted for its small size and coming pre-installed with Linux. With a diagonal size of 11 inches, it would take a big hamster wheel to carry it like this.&lt;br /&gt;
&lt;br /&gt;
{{w|Omniwheel}}s are wheels with rollers mounted on the edge to allow the wheel to slide sideways. The wheels in the drawing look more like {{w|Mecanum wheel}}s, which have rollers mounted at an angle to the edge. Both Omniwheels and Mecanum wheels are used in omni-directional drive systems, like you would use to drive a hamster ball from the inside.&lt;br /&gt;
&lt;br /&gt;
TCO is {{w|total cost of ownership}}, which is exactly what it sounds like: the purchase price of something, plus all costs of keeping, operating, and/or maintaining that something. It's used in accounting to determine something's true cost-to-value evaluation. In the case of a cat, TCO would primarily consist of food and veterinary care, with possible additions for catsitting services, damage caused by feline misbehavior, etc. For the device in the comic, there would be a small ongoing cost (occasional recharges for the batteries) after the initial investment.&lt;br /&gt;
&lt;br /&gt;
A {{w|Roomba}} is a self-directed robotic vacuum cleaner made by iRobot.&lt;br /&gt;
&lt;br /&gt;
{{w|Python (programming language)|Python}} is a programming language popular among geeks running Linux. Among other features, it has a large number of easily installed 3rd-party libraries which make it easy to add features to programs. In this case, [[Cueball]] is importing the &amp;quot;soul&amp;quot; library to give the new pet a soul – &amp;lt;strike&amp;gt;obviously&amp;lt;/strike&amp;gt; something, that a programming language cannot actually do. {{Citation needed}} This is a reference to [[353: Python]].&lt;br /&gt;
&lt;br /&gt;
The title text refers to the {{w|One Laptop per Child}} project spearheaded by Nicholas Negroponte around 2005, with the goal of building an inexpensive, durable sublaptop that could be distributed to children in developing countries to give them an educational edge.&lt;br /&gt;
&lt;br /&gt;

:Cueball: What are you doing?&lt;br /&gt;
:Megan: Mounting your EEE PC in a hamster ball.&lt;br /&gt;
&lt;br /&gt;
:Megan: Well, the TCO of a cat is like $1000/year, so we're saving money.&lt;br /&gt;
&lt;br /&gt;
:[Cueball is typing.]&lt;br /&gt;
:Megan: Microcontrollers are all wired up. How's the brain coming?&lt;br /&gt;

| titletext = Viruses so far have been really disappointing on the 'disable the internet' front, and time is running out. When Linux/Mac win in a decade or so the game will be over.&lt;br /&gt;
}}&lt;br /&gt;
&lt;br /&gt;
==Explanation==&lt;br /&gt;
[[Cueball]] shows off his virtual fishtank of virus-infected {{w|Virtual machine|virtual}} Windows machines to [[Megan]]. The machines nominally have {{w|Trojan_horse_(computing)|mail trojans}}, {{w|Warhol worm}}s, all sorts of {{w|polymorphic virus}}es, and explicitly {{w|Blaster (computer worm)|Blaster}} and {{w|w32.welchia}}. Cueball relates to the viruses as though they are fish, and hopes that they are all getting along together nicely. This is because part of {{w|w32.welchia|welchia's}} malicious payload was to remove the {{w|Blaster (computer worm)|Blaster Worm}}&lt;br /&gt;
, effectively destroying it.&lt;br /&gt;
&lt;br /&gt;
It would be possible to set up a virtual fishtank as described.  The main issue would be to make sure that you don't accidentally let anything escape from the fishtank.  Consider it like a smallpox lab.  Also, some viruses are quite malicious {{Citation needed}} and will prevent a computer from running normally, or at all.  An aquarium of dead computers would not be very interesting to watch.&lt;br /&gt;
&lt;br /&gt;
The first part of the title text refers to the difficulty viruses have in the common doomsday threat of &amp;quot;disabling the internet&amp;quot; as a whole. SQL Slammer had some brief success. The second part of the title text indicates that Randall believes A) that Linux and Mac OS X are inherently less vulnerable to virus attacks than Windows, and B) that Windows will become less important and disappear, so the virus writers had better get their act together soon.&lt;br /&gt;
&lt;br /&gt;
It is not certain how justified this opinion is.  Six years after this comic was written, Windows still dominates the desktop, and Linux and OS X are not ''that'' much harder to attack with viruses. A side issue is the wild growth in 'smart devices' connected to the internet, powered by non-traditional operating systems such as iOS and Android. Desktop operating systems such as Windows, Linux and OS X are ''all'' becoming less relevant (although note that Android is based on the Linux kernel and iOS is based on OS X), so both the operating system war and the struggle against computer viruses are still &amp;quot;anyone's game&amp;quot;.&lt;br /&gt;
&lt;br /&gt;
Something similar to this is now online (as of 02014-06-29; not sure when it first started), with some differences from the system described by this comic. Instead of executing email attachments, the 7 VM's run files uploaded to http://wecan.hasthe.technology/ by the public, making it more of a public playground aquarium than a private fishtank. Instead of wiping machines at random, each VM runs a virus scanner every 24 hours.&lt;br /&gt;

:[Megan looking at a large screen with many green and red squares. The squares have writing in them and lines connecting them.]&lt;br /&gt;
:[Side view. The screen is a huge LCD connected to a wireless router.]&lt;br /&gt;
:Cueball: Pretty, isn't it?&lt;br /&gt;
:Megan: What is it?&lt;br /&gt;
:Cueball: I've got a bunch of virtual Windows machines networked together, hooked up to an incoming pipe from the net. They execute email attachments, share files, and have no security patches.&lt;br /&gt;
:Cueball: Between them they have practically every virus.&lt;br /&gt;
:Cueball: There are mail trojans, warhol worms, and all sorts of exotic polymorphics. A monitoring system adds and wipes machines at random. The display shows the viruses as they move through the network. Growing and struggling.&lt;br /&gt;
:[Cueball walks past the girl and touches the monitor.]&lt;br /&gt;
:Megan: You know, normal people just have aquariums.&lt;br /&gt;
:Cueball: Good morning, Blaster. Are you and W32.Welchia getting along?&lt;br /&gt;
:Cueball: &amp;lt;u&amp;gt;Who's&amp;lt;/u&amp;gt; a good virus? You are! Yes, you are!&lt;br /&gt;

&lt;br /&gt;
==Explanation==&lt;br /&gt;
{{w|Donald Knuth}} is a computer science Professor Emeritus at {{w|Stanford University}} who is famous for writing {{w|The Art of Computer Programming}} and developing the &amp;lt;span class=&amp;quot;texhtml&amp;quot;&amp;gt;&amp;lt;span style=&amp;quot;font-family:cmr10, LMRoman10-Regular, Times, serif;&amp;quot;&amp;gt;T&amp;lt;span style=&amp;quot;text-transform:uppercase; vertical-align:-0.5ex; margin-left:-0.1667em; margin-right:-0.125em;&amp;quot;&amp;gt;e&amp;lt;/span&amp;gt;X&amp;lt;/span&amp;gt;&amp;lt;/span&amp;gt; computerized typesetting system. He may not have a mountain hideaway {{Citation needed}} (a reference to ''{{w|Kill Bill}}'', by the way), but he would be one of the best mentors a budding hacker could have.&lt;br /&gt;
&lt;br /&gt;
The {{w|A* search algorithm}} and {{w|Dijkstra's algorithm}} are {{w|Graph traversal|graph search}} {{w|algorithm}}s. And what study of algorithms would be complete without a healthy study about finding complexities? {{w|Computational complexity theory|Time complexity}} is the amount of time an algorithm takes to execute. Upper and lower bounds for complexity is written in {{w|Big O notation}}. Best possible execution of an algorithm is constant time, or O(1), said in words, for any given data set no matter how large the algorithm will always return the answer in the same time. However, constant time is extremely difficult to achieve, linear time (O(n)) is also very good. For more complex algorithms, [http://www.wolframalpha.com/input/?i=plot+x*log%28x%29 O( n*log(n) )] is good, but [http://www.wolframalpha.com/input/?i=plot+x*log%28log%28x%29%29 O( n*log(log(n)) )] is better. (Note that logarithms in different bases are proportional to each other. So this would hold true for any base &amp;gt;1.)&lt;br /&gt;
&lt;br /&gt;
From the evidence that [[Mrs. Roberts]] has two children, a daughter named [[Elaine Roberts|Elaine]], and a younger son named Bobby (presumably [[Little Bobby Tables|Bobby]]'); DROP TABLE students;--), we can assume that she is the same mother from [[327: Exploits of a Mom]]. Of course, the title text here explains that Elaine is only her middle name. In [[327]] we learned her first name is &amp;quot;Help I'm trapped in a driver's license factory&amp;quot;. Mrs. Roberts appears to have had fun naming her children.&lt;br /&gt;

&lt;br /&gt;
==Transcript==&lt;br /&gt;
:[Cueball standing near a friend, who is on the floor near the armchair.]&lt;br /&gt;
:Friend: So the greatest hacker of our era is a cookie-baking mom?&lt;br /&gt;
:Cueball: Second-greatest.&lt;br /&gt;
:Friend: Oh?&lt;br /&gt;
&lt;br /&gt;
:[A young Elaine with a ponytail is laying on the floor looking at the screen of a computer that appears to have been pieced together. A younger Bobby is finger painting at an easel.]&lt;br /&gt;
:Mrs. Roberts had two children. Her son, Bobby, was never much for computers, but her daughter Elaine took to them like a ring in the bell.&lt;br /&gt;
&lt;br /&gt;
:[The back of a car is in frame. Mrs. Roberts is waving goodbye to her daughter who is wearing a backpack and is holding a walking stick. She is about to begin climbing a staircase built into a mountain.]&lt;br /&gt;
:When Elaine turned 11, her mother sent her to train under Donald Knuth in his mountain hideaway.&lt;br /&gt;
&lt;br /&gt;
:[Donald Knuth is standing with a pointing stick at a chalk board with graph traversal patterns on it.]&lt;br /&gt;
:For four years she studied algorithms.&lt;br /&gt;
:Knuth: Child—&lt;br /&gt;
&lt;br /&gt;
:[Knuth whips around slashing the stick like a sword. Elaine jumps and lands on the stick.]&lt;br /&gt;
:Knuth: Why is A* search wrong in this situation?&lt;br /&gt;
:''swish''&lt;br /&gt;
:Elaine: Memory usage!&lt;br /&gt;
:Knuth: What would you use?&lt;br /&gt;
:Elaine: Dijkstra's algorithm!&lt;br /&gt;
&lt;br /&gt;
:[They are outside both working on a chalkboard with a separator down the middle so they cannot look at each other's work. Elaine is no longer wearing her hair in a ponytail.]&lt;br /&gt;
:Until one day she bested her master&lt;br /&gt;
:Knuth: So our lower bound here is O(n log n)&lt;br /&gt;
:Elaine: Nope. Got it in O(n log (log n))&lt;br /&gt;
:And left.&lt;br /&gt;
&lt;br /&gt;
==Trivia==&lt;br /&gt;
*[[Mrs. Roberts]]' son Bobby, might be the &amp;lt;code&amp;gt;Robert'); DROP TABLE students;--&amp;lt;/code&amp;gt; a.k.a. &amp;quot;[[Little Bobby Tables]]&amp;quot; in [[327: Exploits of a Mom]], it certainly seems a little too close to call a coincidence.&lt;br /&gt;
*In this [http://www.youtube.com/watch?v=zJOS0sV2a24#t=21m30s Google-speech] Donald Knuth personally asked [[Randall]] what his ''n*log(log(n))'' algorithm for searching was, and Randall referred him to Elaine.&lt;br /&gt;

&lt;br /&gt;
The title text says that the reason why Beret Guy's hat stays on his head, even when upside down (in which gravity would tend to make the hat fall off) is due to Beret Guy's stapling the beret on his head. Such a process is strange and painful {{Citation needed}}, but [http://what-if.xkcd.com/6/ Beret Guy does not seem to get bothered by foreign objects being lodged in his head.]&lt;br /&gt;

Hey, perhaps we should mention something about the site http://wecan.hasthe.technology?
