162.158.111.73: /* Title text explanation mis-read */ new section

This is easy! Don't factor it - just multiply by 25 and if that ends in two zeros, but not four zeros then it's a leap year, at least most of the time.....17:25, 29 December 2017 (UTC)

This is easy! Don’t factor it - just convert it into a binary and look at the 2 least significant bits. If they are 00 the number is multiple of four. —[[Special:Contributions/172.69.33.35|172.69.33.35]] 17:37, 29 December 2017 (UTC)

This is easy! Don't factor it - just subtract 4 repeatedly. If you end up at 0, it's divisible. If you end up at 1, 2, or 3, it's not. -- 17:55, 29 December 2017 (UTC)

== Title text explanation mis-read ==

Explanation of title text is incorrect:

"The title text refers to calculating the date of Christmas; again, this is a trivial exercise, because Christmas is always December 25."

Title text states 'day of Christmas', not 'date...'. The day changes each year and so does require calculation.

162.158.111.73: Removed what's probably a spam link

{{comic
| number = 195
| date = December 11, 2006
| title = Map of the Internet
| image = map of the internet.jpg
| titletext = For the IPv6 map just imagine the XP default desktop picture.
}}

==Explanation==
On the map, all allocated {{w|IPv4}} address blocks (as of 2006) are shown using a fractal mapping. (The {{w|Hilbert curve}} is used: the pattern is demonstrated at the bottom of the image.) In February 2011, the final remaining IPv4 blocks were allocated to the {{w|Regional Internet registry|Regional Internet registries}}, and so today there would no longer be any green spaces outside of Class E addresses (above 240 through 255, excluding the Broadcast address of 255.255.255.255).

In the early 1990s, corporations and governments could register an entire {{w|Classful network|class A}} segment (one 256th of the total space), but later it was divided into smaller parts because of a lack of space.

This leads to the title text, which mentions {{w|IPv6}}. This protocol has so many addresses that only a swarm of nanobots could exhaust them (see [[865: Nanobots]]). The default desktop picture in Windows XP is a green landscape, and the joke is that since barely any of the addresses are allocated yet, the IPv6 map would just be a green landscape.

Later, Randall actually drew some "real" maps of the Internet, or at least its online Communities (see [[256: Online Communities]] and [[802: Online Communities 2]]).

==Transcript==
:Map of the Internet The IPv4 Space, 2006 This chart shows the IP address space on a plane using a fractal mapping which preserves grouping--any consecutive string of IPs will translate to a single, compact, contiguous region on the map. Each of the 256 numbered blocks represents one 8 subnet (containing all IPs that start with that number). The upper left section shows the blocks sold directly to corporations and goverments in the 1990's before the RIRs took over allocation.

1889: xkcd Phone 6

==Explanation==
{{incomplete|All features need an explanation, the version number war and title text as well. Do NOT delete this tag too soon.}}

This is the sixth entry in the ongoing [[:Category:xkcd Phones|xkcd Phone series]], released the day after Apple announced their new iPhone X with facial recognition features.

===List of features (clockwise from center/top)===

; Front camera (centered for eye contact during video chat)

: Front camera is a common feature of smartphones. The camera lens is located on the same side of the phone's case as the main screen and therefore it is possible to capture the image of the user's face looking at the screen and display the interlocutor's face on the screen simultaneously, enabling video chat. However, as the camera is usually located above the screen, a user looking at the displayed image of the other person directs his or her eyes at the center of the screen and not at the camera's lens. This is very visible on the other end of the chat as if the person talking was looking down and not in the interlocutor's face which is an uncomfortable situation for most people. For this reason, professionals involved in movie or TV-making, like actors or reporters, are trained to look straight into the camera's lens while talking, which creates impression of looking straight at the viewer's face. During a video chat, however, looking into the lens of an above-screen camera does not allow one to see the interlocutor's face clearly because it is then in the peripheral field of vision.

: To solve this conundrum, Randall proposes locating the camera lens right in the middle of the screen. Therefore the user looking at the screen to see the other person's face would be also looking at the lens, creating an impression of a straight look on the other end of the chat. This is absurd since the lens would then take place of some of the center pixels of the screen, not allowing the display the center part of the captured image of the other person's face (like eyes and/or lips) which is most important for nonverbal communication. Such location of the camera lens would also likely interfere with touch-screen function. It will make other applications on the phone difficult to use, since virtually no user interface is designed to accommodate for a blind spot in the center.

; Full-width rear camera

: Phone cameras tend to have lenses which are quite small and round or square -- same width as height. Full-width makes it sound like the camera lens is really wide, as in a long oval or rectangle shape. This generally would not accomplish anything worthwhile, unless it allowed you to take one-shot panorama photos?

; CDC partnership - phone automatically administers seasonal flu vaccine to cheek every year

: U.S. {{w|Centers for Disease Control and Prevention}} is a government agency tasked with addressing public health concerns such as infectious diseases, including seasonal flu. A common way of limiting spread of an infectious disease is {{w|Vaccine|vaccination}}, which most often involves administering a specially prepared medicine via an {{w|intramuscular injection}}. This features implies that the phone would automatically perform such an injection once a year, by shooting a needle out of a small aperture while the user is holding the phone to his or her cheek during a call.

; 12-function

: Most smartphones can be used for more than 12 different things.{{Citation needed}}

; Dishwasher safe

: Usually a feature of plastic containers or fancy dishes. Unlikely to appear on a smartphone, though potentially useful if you need to clean your screen.

; GPS transmitter

: Many smartphones have a receiver for the Global Positioning System, which allows a phone to compute its position based on signals from the constellation of GPS satellites. However, a device with a "GPS transmitter" would broadcast signals that would interfere with the GPS receivers of all devices nearby

; 3-G acceleration

: Usually, a phone is 3g compatible if it uses a certain standard ("third generation") for data transmission. However, 3-G acceleration implies the phone can accelerate at a rate or 3 times the acceleration of gravity, or approximately 30 m/s².

; Portable, solar-heated
: Portability is pretty much the entire point of using a ''mobile'' phone, so advertising portability is rather pointless. Solar ''power'' charging could be a very useful feature on a phone, but solar ''heating'' usually applies to plumbing, where a water tank is heated by the sun and used to supply hot water to taps. Technically, as the sun heats up everything on Earth, the phone is in fact solar heated.

;Pore-cleaning strip

: Something sticky on that location would be very annoying for people trying to make a call with beards.

; Maximum strength

:Medicines are often sold a "Maximum stength", as in the highest does allowed by law or allowed without a prescription. For phones, there are sometimes "hardened" or "ruggedized" versions which are designed to survive harsher environmental conditions such as surviving drops and collisions, excessive water and dust, etc. So Maximum strength could indicate a "ruggedized" phone, though a screen that extended past the edges would likely have the opposite effect.

; Never needs sharpening

: Phones do not need to be sharpened in the first place.{{Citation needed}} This is a feature more likely to be used in a knife advertisement or apply to a mechanical pencil, which does have the advantage of never needing to be sharpened as opposed to a normal pencil.

; Can survive up to 30 minutes out of water

: This is a play on the common IP-rating of water resistance, which is typically rated for submersion to a rated depth for 30 minutes. A phone which could only be used or carried for 30 minutes and then needed to be immersed in water would be rather inconvenient.

; Exclusive Audubon Society app identifies birds and lets you control their flight

: {{w|National Audubon Society}} is a non-profit organization dedicated to conservation of nature, mainly of birds, also organizing open {{w|birdwatching}} events. An app that identifies bird species, as for example from a photo of a bird made by the smartphone itself, would be cool. An app allowing you to control the bird's flight would be way cooler, but it is not possible at the current state of technology{{Citation needed}} - and it would fly in the face of the Audubon Society core activity. This is a reference to {{w|Unmanned_aerial_vehicle|drones}} (artificial "birds") which are often controlled by a smartphone app. This may also be a reference to xkcd 1425 Tasks, in which an app that can recognize if a bird is on camera is proposed.

; Extra screen

:Because of the center camera, an additional section of screen was added. This is similar to the new iPhone, which also has a few extra pixels up there.

; Wireless charging port

:Wireless charging has no wires, and needs no port.

; Safe for ages 6-8 months, 10 months, 18 months-3 years, and 12 years and older

:Usually an item is deemed safe for a particular age or older, or (in the case of toys) is recommended for a particular age range. This is unusual in that it's a hodge-podge of age ranges with no apparent reason why some ages are safe and others are not.

; Screen goes past the edge

:An over-exaggerated version of the "edge to edge" displays in recent generations of smartphones

; High thread count CPU

:A CPU thread is a task the CPU performs. Several threads may share memory making them a process. A operating system distributes the CPU's time over all active threads. CPU's don't generally have a limit on the number of threads (some operating systems do), however with a certain number the amount of cycles per thread becomes too low to be of much practical use. This seems to be a joke about bedding, where high thread count is actually a reasonably advertizable statistic.

; Shroud of Turin-style facial transfer unlock

:The {{w|Shroud of Turin}} is claimed to display an image of the face of {{w|Jesus Christ}}, appearing as if it was transferred to the cloth. Presumably, to unlock this phone, the user must press their face against it.

; Fonts developed by NASA

: NASA's expertise is not in fonts, and the fonts on almost all modern phones are the same.

; Includes applicator

: What sanitary towel packages often say.

; Burns clean coal

: There is a push for clean energy production as a result of increased awareness of global warming. While it may be useful for a phone to be able to produce its own energy, coal is by definition not a clean energy source because it produces carbon dioxide. The phone is not stated to have a vent for the CO2 to escape, which would technically make the coal "clean" as it is not entering the atmosphere. However, the gas is instead trapped inside the phone, which will quickly ruin it through a combination of heat and pressure.

; Pre-seasoned

:Pre-seasoned typically refers to cast iron cookware which is ready to use out of the box, as opposed to needing to season it with oil and heat. It can also refer to packaged meats which are ready to cook without needing to be seasoned with herbs and spices.

; Broad-spectrum SPF 30

:The xkcd phone somehow gives an SPF 30 level of skin protection from the sun.

; College-ruled

:College-ruled is a style of notebook paper having narrower lines in order to fit more text per page.

; Sterile packaging

:Useful for medical supplies, less so in a phone.

; Radium backlight

:The discovery of the phosphorescent element radium sparked a brief fad in which some watch makers painted watch faces or hands with the substance so the time could be read at night. However, it was eventually realized that regular exposure to radium could result in radiation poisoning, particularly for the workers assembling and painting the watches. A radium-based backlight would therefore be both potentially dangerous (especially for an object carried on one's person much of the time) but also largely useless, as the phosphorescence of radium is rather dim compared to conventional phone back lights.

; 4K pixels (50×80)

:This refers to having 4,000 pixels in the screen in total, rather than a screen width of ~4000 pixels. TV's advertised as "4K" are typically up to 4096 × 2160 pixels, or 8.8 million pixels. That would be outstanding for a cell phone whereas 4,000 pixels total would be horrendous. As a comparison, the old Commodore VIC-20 with a resolution of 176 × 184 would have over 8 times the pixels of this phone. It is however quite close to the screen resolution of the sturdy Nokia 3310, boasting a total of 4032 pixels positioned 84 × 48.

: Usually a feature of plastic containers or fancy dishes. Unlikely to appear on a smartphone, though potentially useful if you need to clean your screen.

; GPS transmitter
Many smartphones have a receiver for the Global Positioning System, which allows a phone to compute its position based on signals from the constellation of GPS satellites. However, a device with a "GPS transmitter" would broadcast signals that would interfere with the GPS receivers of all devices nearby
:

; 3-G acceleration

: Usually, a phone is 3g compatible if it uses a certain standard for data transmission. However, 3-G acceleration implies the phone can accelerate at a rate or 3 times the acceleration of gravity, or approximately 30m/s/2.

; Portable, solar-heated

: Portability is pretty much the entire point of using a *mobile* phone, so advertising portability is rather pointless. Solar *power* charging could be a very useful feature on a phone, but solar *heating* usually applies to plumbing, where a water tank is heated by the sun and used to supply hot water to taps. Technically, as the sun heats up everything on the earth, the phone is in fact solar heated.

;Pore-cleaning strip

; Maximum strength

:

; Never needs sharpening

: Phones do not need to be sharpened in the first place.{{Citation needed}} This is a feature more likely to apply to a mechanical pencil, which does have the advantage of never needing to be sharpened as opposed to a normal pencil.

; Can survive up to 30 minutes out of water

:This is a play on the common IP-rating of water resistance, which is typically rated for submersion to a rated depth for 30 minutes. A phone which could only be used or carried for 30 minutes and then needed to be immersed in water would be rather inconvenient.

; Exclusive Audubon Society app identifies birds and lets you control their flight

:

; Extra screen

:Because of the center camera, an additional section of screen was added.

; Wireless charging port

:Wireless charging has no wires, and needs no port.

; Safe for ages 6 – 8 months, 10 months, 18 months – 3 years, and 12 years and older

:

; Screen goes past the edge

:An over-exaggerated version of the "edge to edge" displays in recent generations of smartphones

; High thread count CPU

:High thread count typically applies to bedding, not CPU threads.

; Shroud of Turin-style facial transfer unlock

:The Shroud of Turin apparently displays an image of the face of Jesus, appearing as if it was transferred to the cloth. Presumably, to unlock this phone, the user must press their face against it.

; Fonts developed by NASA

:

; Includes applicator

:

; Burns clean coal

: There is a push for clean energy production as a result of increased awareness of global warming. While it may be useful for a phone to be able to produce its own energy, coal is by definition not a clean energy source because it produces carbon dioxide. The phone is not stated to have a vent for the CO2 to escape, which would technically make the coal "clean" as it is not entering the atmosphere. However, the gas is instead trapped inside the phone, which will quickly ruin it through a combination of heat and pressure.

; Pre-seasoned

:Pre-seasoned typically refers to cast iron cookware which is ready to use out of the box, as opposed to needing to season it with oil and heat. It can also refer to packaged meats which are ready to cook without needing to be seasoned with herbs and spices.

; Broad-spectrum SPF 30

:The xkcd phone somehow gives an SPF 30 level of skin protection from the sun.

; College-ruled

:College-ruled is a style of notebook paper having narrower lines in order to fit more text per page.

; Sterile packaging

:

; Radium backlight

The discovery of the phosphorescent element radium sparked a brief fad in which some watch makers painted watch faces or hands with the substance so the time could be read at night. However, it was eventually realized that regular exposure to radium could result in radiation poisoning, particularly for the workers assembling and painting the watches. A radium-based backlight would therefore be both potentially dangerous (especially for an object carried on one's person much of the time) but also largely useless, as the phosphorescence of radium is rather dim compared to conventional phone back lights.

; 4K pixels (50x80)

:This refers to having 4,000 pixels in the screen, rather than a screen width of ~4000 pixels.

{{comic
| number = 1885
| date = September 4, 2017
| title = Ensemble Model
| image = ensemble_model.png
| titletext = I'm in talks with Netflix to produce an alternate-universe crime drama about the world where sliced bread was never re-legalized, but it's going slowly because they keep changing their phone numbers and the door lock codes at their headquarters.

{{incomplete|Created by a BOT - Please change this comment when editing this page. Do NOT delete this tag too soon.}}

Actor {{w|Will Smith}} famously turned down the lead role of {{w|Neo (The Matrix)|Neo}} in ''{{w|The Matrix}}'', instead taking the role of Captain James T. West in the widely-panned action-comedy ''{{w|Wild Wild West}}''. The role of Neo ultimately went to {{w|Keanu Reeves}}.

In a ensemble model, forecasters run many different versions of a whether model with slightly different initial conditions. This helps account for uncertainty and shows forecasters a spread of possible outcomes.

[Picture of several grey overlapping lines emitted from a point, then gradually diverging]

Numbers in a typical ensemble:

A universe where...

...rain is 0.5% less likely in some areas

...wind speeds are lightly lower

...pressure levels are randomly tweaked

...dogs run slightly faster

...there is one extra cloud in the Bahamas

...Gemrany won WWII

...Snakes are wide instead of long

...Will smith took the lead in ''The Matrix'' instead of ''Wild Wild West''

...Swimming pools are carbonated

...Sliced bread, after being banned in January 1943, was never re-legalized.
