Some unique looking variable names would be X and x in the fonts Webdings, Wingdings, Wingdings 2, and Wingdings 3. 
They are respectively as follows:

As well as esolangs, among which I would consider the likes of Whitespace and b****fuck as potential inspirations, I think I'm also minded of TempleOS and its creator as vaguer but possibly still related influences...

I added an explanation of what a variable is and why it's bad to have every one named X. It's pretty rudimentary though, hope someone more experienced than me will improve it. [[User:Unpopular Opinions|Goodbye, world!]] ([[User talk:Unpopular Opinions|talk]]) 04:39, 21 May 2020 (UTC)

:Forth basically doesn't use variable names. Commands operate on and consume the last number mentioned. A Forth program "1 2 3 . . ." prints 3, then 2, then 1. "2 3 + ." prints 5 I think??
:In Microsoft "Transact-SQL" you can script variables named starting @ and temporary objects starting #. I promise I try to resist naming objects @ or # and especially if @ or # is going to be a different object in each program... or is not.

:Yeah, but C++ does that shit either '''unintentionally''' or '''at user demand''' (although, to be clear, I'm not saying it's any good; C++ and Java are possibly the worst programming languages in terms of shoddy design).

:Those look like pretty sane language features; just looks weird because of the Eliza effect; those keywords don't behave like you'd expect them to based on experience of other languages. In the first example, you can certainly do that in Perl using "if (defined wantarray)"; it's just unusual (but comprehensible) to name the keyword "return". What language is that?

If X is the only variable name, can it be omitted? For example, writing a single-argument function name in a different font to imply which X should be treated as its argument. And that gets me wondering how the source is stored; will the IDE allow use of fonts not installed on your system? Will the compiler fail if it can't find the font, requiring you to track down all of the fonts a developer used in order to compile their code? And what would be the legality of mixing open-source code and proprietary fonts? [[User:Angel|Angel]] ([[User talk:Angel|talk]]) 09:57, 21 May 2020 (UTC)

:Well, I've got this one with just four operands, everything's a relative address in 4-cored circular memory and there's no paractical differentiation between the packed opcodes, addresses and data (or their 2-bit lower-limit boundaries) when operated upon from elsewhere.

Isn't the fixed vs variable width a pun on the variable's internal size, eg. a 64-bit integer [fixed width) vs a string (variable width) ?

I sure hope this new language at least supports indexed tuples. If so, that wouldn't be so bad, unless for some reason I needed more than one tuple in the same scope.[[User:Whiteheadw|Whiteheadw]] ([[User talk:Whiteheadw|talk]]) 23:01, 21 May 2020 (UTC)

I'm not sure that this: "ℝ denotes the set of natural numbers, and is distinct from R" is strictly true. The way I was taught is that boldfaced R does stand for the real numbers, except when it doesn't, and blackboard-bold ℝ (and Q, and C, and Z) are just what you write on the blackboard since it's impossible to make a clear boldfaced R with chalk.
Not that the main point doesn't stand--too many circumstances where plain P, bold P, italic P, and fancy curly script P all mean different things. [[Special:Contributions/162.158.62.105|162.158.62.105]] 18:57, 22 May 2020 (UTC)

True fossils have remineralised so generally do not have DNA left. They are merely the shadow of a previous life.

474: Turn-On

2020-05-05T06:54:18Z

172.68.143.30: /* Explanation */

{{comic
| number = 474
| date = September 10, 2008
| title = Turn-On
| image = turn-on.png
| titletext = Supercollider? I 'ardly know 'er!
}}

==Explanation==
This comic refers to the first start-up (turn-on) of {{w|CERN|CERN's}} {{w|Large Hadron Collider}} (LHC). There was a theoretical concern that that the LHC experiments could create a {{w|black hole}} which would suck in our planet.

[[Cueball]] uses this concern when telling [[Megan]] this could be their last night on Earth, but since the scene is in a bar this is just another lame entry he uses because he just wants to spend the night with her.

Megan answers as a physicist and explains that first of all they will not start colliding particles just because they actually turn-on the collider. That will take a while during which everything needs to be checked. Secondly scientists have determined that the fears are unfounded — among other things because cosmic rays have already been bombarding the Earth with particles even more energetic than those created by the LHC. Thus if the LHC could create a black hole that would suck up the Earth, then that would have happened long ago due to the cosmic rays. (At present time the collider has been colliding particles for years, and if you read this line on or near Earth, then the Earth is probably still here; if you read it in a galaxy far away from the Milky Way, then it is somewhat more plausible that Earth may have been destroyed in the time that the signal took to reach you.)

Cueball feels rejected by her answer and turns away to leave her, but she calls him back explaining very directly that she did not say "no" to his request (to try to stay a night with her). Also as she is a physics grad student she needs an excuse to party — the excuse being that the LHC is turned-on.

Cueball feels encouraged and continues his attempt to get her in to bed. But in his next sentence he unwittingly uses three of the six {{w|quark}} flavors ({{w|up quark}}, {{w|charm quark}}, and {{w|strange quark}}). Megan continues to be very direct when asking if she has to be on top or bottom (when they are going to have sex). But this is also a sentence she chooses so she can continue using quark flavors ({{w|top quark}} and {{w|bottom quark}}). Cueball is flustered and complains that she is assuming too much since he hasn't even bought her a drink. Megan then makes it even worse when she makes an order of two {{w|whiskey sour}}s straight down - to use the final flavor ({{w|down quark}}).

Maybe she just teases Cueball (with her knowledge about the LHC and quarks), or else she is actually so turned-on by the LHC Turn-On that she wishes to have sex with Cueball as soon as possible.

The quarks are some fundamental particles the LHC is generating. All six {{w|Flavour (particle physics)|flavors}} of quarks are in the last panel: up, down, top, bottom, charm and strange. They are also referenced in [[1418: Horse]], [[1621: Fixion]] and in [[1731: Wrong]], the latter also mentioning the up and down flavor. The mention of the drinks being served "straight down" is a reversal of the common bartending term "straight up", but there is no "straight down" in bartending.

The title text is of course a very old joke "[http://urbandictionary.com/define.php?term=I+Hardly+Know+Her I 'ardly know 'er!]". In this case Supercollider (another name for the LHC) should be misunderstood as "(Did you) Supercollide her?", which you could put into a (nasty?) sexual context. Using this sentence at the wrong moment could be bad for a nice romance. This could be a reference to the ''{{w|Futurama}}'' episode "{{w|That's Lobstertainment!}}", in which Humorbot 5.0 tells a similar supercollider joke.

==Transcript==
:[Cueball walks up to Megan sitting at bar.]
:Cueball: So, the LHC's turning on. This could be our last night on earth.
:[While Beret Guy as a bartender walks into the frame Megan replies without turning]
:Megan: Gimme a break. They're not even colliding yet, and it won't do anything cosmic rays haven't.
:[Cueball turns and walks away. But then Megan turns towards him and says:]
:Megan: Hey, I didn't say no.
:Megan: I'm a physics grad student. I need the excuse to party.
:[Cueball turns back and they talk:]
:Cueball: So, you're up for a night with a charming stranger?
:Megan: Depends. Top or bottom?
:Cueball: Hey, I haven't even bought you a drink.
:Megan: Barkeep, two whiskey sours, straight down.
