I would totally buy a blank book. I could hollow them out to make boxes, or wire up the insides to build a revolving door, or hire an artist to draw wonderful images in them to put on display for anyone who comes over to my home.

Interestingly, this is exactly the argument used to explain why reading books is better than watching TV: TV gives too much of the ready context, while a book allows the reader to fill in the blanks with his own imagination. The empty books just go one step further. [[Special:Contributions/108.162.246.11|108.162.246.11]] 22:15, 21 January 2014 (UTC)
:I dunno, I mean, there's plenty of space in TV to work in stuff, exercise your imagination. In my view a book is for having stuff in it. A story in a book gives you a structure to build on, a framework that lets you build higher than you would go on your own. -Pennpenn [[Special:Contributions/108.162.250.162|108.162.250.162]] 04:19, 16 October 2015 (UTC)

I write short stories all the time but nobody reads them.
Maybe I should get a printer?

"Telling someone who trusts you that you're giving them medicine, when you know you're not, because you want their money, isn't just lying--it's like an example you'd make up if you had to illustrate for a child why lying is wrong."

I think it is worse when vets do it to cattle and sheep. You never get to hear the farmer saying "Bah!"
though. Odd, that.[[User:Weatherlawyer| I used Google News BEFORE it was clickbait]] ([[User talk:Weatherlawyer|talk]]) 19:10, 22 January 2015 (UTC)

:"Huge World" would imply that the game type is first or third person, with the player taking control of a character in that world. In this sense, I think it's appropriate for the controls to be in reference to movement of the character. If the game type were management or simulation, I think you would be correct.

Perhaps this is a reference to the recent Public Policy Polling survey http://publicpolicypollling.blogspot.com/2011/07/evaluating-god.html whcih asked people about God's job performance. God received his highest rating on his "handling of creating the universe" with 71% in favor of the universe and 5% opposed.

"gun violence, sexual violence, poverty", etc, are really human's problems rather than Earth's problems.

To be honest I think this comic is a bit lazy for xkcd standards. The whole joke of "I went outside today, the graphics are amazing but controls suck" is years old and was never really good in my opinion. I've seen several comics where Randal reused old jokes and put a clever spin on them or extended them in a new fashion that I'm disappointed Randall essentially copy&pasted this one. [[User:Bischoff|Bischoff]] ([[User talk:Bischoff|talk]]) 16:26, 21 August 2019 (UTC)
:Personally, I was hoping for something on the announcement of KSP 2 :P

I'm reminded of [https://www.smbc-comics.com/comic/2014-09-26 this comic] by the SMBC guy (better known as Emergency Backup Randall Munroe) which features a hypothetical site which can host such a review, and also two Black Hats. Some folks also made a subreddit that actually implements the idea. --[[Special:Contributions/172.68.11.167|172.68.11.167]] 18:03, 21 August 2019 (UTC)

Multiplayer sucks. Needs to have a single-player mode. [unsigned]

Is this the first time that Randall has explicitly drawn himself in a comic? Does this make it official that Cueball is Randall (or Randall's alter-ego)? [[User:Stevage|Stevage]] ([[User talk:Stevage|talk]]) 05:09, 22 August 2019 (UTC)

Is this serious: "Earth is a completely real object[citation needed]"? I never thought this could be fake news. :-)

{{circuit-diagram-part|X=22|Y=513|W=97|H=61|image=circuit_diagram-022-513-097-061-esf.png|text=A label reading "Electrons Single File". If this happens, the resistance in this section of wire would be rather high.}}
{{circuit-diagram-part|X=256|Y=619|W=29|H=39|image=circuit_diagram-256-619-029-039-ground.png|text=A ground connection.}}
{{circuit-diagram-part|X=589|Y=600|W=58|H=46|image=circuit_diagram-589-600-058-046-vibrator.png|text=A vibrator, which would be a motor with an off-center weight attached to it.}}

{{circuit-diagram-part|X=662|Y=822|W=73|H=109|image=circuit_diagram-662-822-073-109-holy-ground.png|text=A ground connection, in a beaker labeled "{{w|Holy Water}}", possibly creating {{w|Holy ground (religion)|holy ground}}.}}
{{circuit-diagram-part|X=197|Y=740|W=48|H=55|image=circuit_diagram-197-740-048-055-speed.png|text=A sign indicating a speed limit of 55 MPH. This is a rather typical road sign, but inappropriate for a circuit diagram.}}
{{circuit-diagram-part|X=238|Y=706|W=100|H=116|image=circuit_diagram-238-706-100-116-flipflop.png|text=A pair of NOR gates wired as a SR (set-reset) {{w|Flip-flop (electronics)|flip-flop}}. The label reads "May use an actual sandal instead", which is a play on the meanings of the term "{{w|Flip-flops|flip-flop}}".}}
{{circuit-diagram-part|X=322|Y=708|W=70|H=54|image=circuit_diagram-322-708-070-054-holdingpen.png|text=Something that could be the side view of a fence, labeled "Holding Pen".}}
{{circuit-diagram-part|X=339|Y=777|W=42|H=49|image=circuit_diagram-339-777-042-049-knot.png|text=A simple overhand knot. Also looks like a pretzel, which would have pretty high resistance.}}

If this were a real ECG trace, the absence of large, clear {{w|P wave (electrocardiography)|P waves}} might indicate {{w|Atrial Fibrillation|fine atrial fibrillation}}, but in some recording configurations, P waves are sometimes lost in the noise anyway. Additionally, without a time scale to tell us the ventricular heart rate, it is impossible to make a strong educated diagnosis of any hypothetical disease at all. If we assume it is atrial fibrillation, is not clear if Randall intended this, or if he is just not familiar with how a normal ECG should look. Lastly, it does not appear that this is an actual ECG machine, but simply a bent wire, much like the "Not a resistor" label nearby.}}

{{circuit-diagram-part|X=504|Y=860|W=34|H=41|image=circuit_diagram-504-860-034-041-resistor.png|text=A resistor labeled "?". Presumably this means the resistance is unknown.}}
{{circuit-diagram-part|X=459|Y=828|W=55|H=38|image=circuit_diagram-459-828-055-038-resistor.png|text=A resistor labeled "YES". Likely another improper unit - a reference to boolean values YES (TRUE) and NO (FALSE). Depending on the limits of a circuit, a resistor would still have a YES boolean value. Possibly indicating that this is a real resistor, as opposed to the one above it in the circuit, labeled "not a resistor."}}
{{circuit-diagram-part|X=389|Y=774|W=58|H=53|image=circuit_diagram-389-774-058-053-resistor.png|text=A resistor labeled "8 mm".}}

Apparently the wire is or must be physically bent into a zig-zag shape, which would not serve much useful purpose in a low frequency or DC circuit, or perhaps it reflects the fact that any wire has a certain (small) amount of resistance just by being a wire. In a {{w|Radio frequency|high frequency circuit}} this can be actually useful, as the shape and length of the {{w|Transmission line|transmission line}} alters the {{w|Electrical impedance|impedance}} of the line.

{{circuit-diagram-part|X=415|Y=863|W=82|H=24|image=circuit_diagram-415-863-082-024-unsure.png|text=A symbol for a feedthrough capacitor, labeled "3 Liters". Probable word-play on "capacity/capacitor." Also similar to the symbol for an orifice or flow restriction used on plumbing or hydraulic diagrams, in which case the "3 Liters" might mean 3 liters per minute or per second.}}
