Hello Zorp.

@Adám Of course you're free to answer it in some other language, but it'll probably be trivial.

Or when two languages have the same first letter (JavaScript and Java) (not that those will be chosen but you know what I mean)

Dude coinheringaahing

@Adám "autological" :Þ

user

@Adám humongous

I'd say YAML, but that doesn't count

Adám

Autological word

An autological word (also called homological word) is a word that expresses a property that it also possesses (e.g., "word" is a word, "noun" is a noun, "English" is English, "pentasyllabic" has five syllables). The opposite is a heterological word, one that does not apply to itself (e.g. the word "long" is not long, "monosyllabic" does not have just one syllable, “dactyl” is not a dactyl). Unlike more general concepts of autology and self-reference, this particular distinction and opposition of "autological" and "heterological words" is uncommon in linguistics for describing linguistic phenomena...

Q: Euler's numerus idoneus

Euler's numerus idoneus, or idoneal numbers, are a finite set of numbers whose exact number is unknown, as it depends on whether or not the Generalized Riemann hypothesis holds or not. If it does, there are exactly 65 idoneal numbers. If not, there are either 66 or 67. For the purposes of this ch...

Dude coinheringaahing

If you have a calculator that can run programs (e.g. TI-82), write notes in those program files

@DLosc I'm heartbroken that Pip doesn't have auto-complete string terminators :(

ngn

@user the thing with maths is, if you're smart enough to cheat successfully, you're probably smart enough to solve the problems anyway

@Dudecoinheringaahing Good idea, although typing in those is hard :/

DLosc

Dude coinheringaahing

user

8:19 PM

Wait, is this standard college stuff or just because you're a math person? Because it sounds painful

Dude coinheringaahing

Like, I hate not getting the answer correct because I forgot that you're supposed to have a negative sign in front of the identity, so technically speaking, I was wrong

@user I'm a maths person :P

user

Oh good

Dude coinheringaahing

I think Stokes' theorem was in the Calc 3 course I took, but it might have been Calc 2

user

Is Calc 2 multivariable calculus? idk how it works in the UK

Dude coinheringaahing

I also don't know how it works in the UK - I took an online US calculus course during Year 12 (I think that's junior year?)

I should probably dig up my notes from that in prep for uni tbh :P

user

8:23 PM

Oh

12th grade is senior year here

Dude coinheringaahing

Year 12 is the second to last year, Year 13 is the last year of high school

DLosc

@Dudecoinheringaahing I'm glad you care enough about Pip to be heartbroken. :) That was a deliberate decision, though. It does make the language a bit less golfy, but it's already never going to beat tacit/stack languages with 256-character codepages, so I'd rather not make it (IMO) uglier just in order to lose less thoroughly.

user

@Dudecoinheringaahing oic

@DLosc Does it really make it all that uglier?

Dude coinheringaahing

@DLosc Just so you know, CJam and Pyth also have auto-complete at EOF strings :P

DLosc

@user Not by much. I've mostly become okay with autoclosing stuff. It's compressed strings that I really can't stand...

@Dudecoinheringaahing I'm aware :P

Dude coinheringaahing

8:27 PM

I can definitely understand not going for compressed strings, especially if its an ascii-only language

@emanresuA Japt

user

8:29 PM

caird would say Jelly is quite readable, DLosc would say Pip is readable, Leo would say Husk is readable, even though they're all unreadable to people like me

emanresu A

@Dudecoinheringaahing Ok, what does DẆḌẒƇṀ do?

Dude coinheringaahing

Even when I was learning Jelly, it was readable (with an explanation). Like, I could see how H,Z would do H, then Z then pair them. Vyxal, Husk, 05AB1E I can mentally parse, if not understand what the builtins do. Japt just doesn't make sense to me

Adám

@emanresuA One of those that have compressed source.

DLosc

Pip's design philosophy has always been "golf language that works pretty similarly to regular languages that you already know." I don't know that all the features live up to that description, and there have rarely been golfing newbies lining up to learn Pip... but I'm gonna stick to my principles even if they don't entirely make sense. :P

@Dudecoinheringaahing Do you mean that the shortcuts are weird? Because other than that, it's a pretty sane language

8:31 PM

@emanresuA Unary is compressed?

emanresu A

@DLosc Unary can be a golfing language

user

I'd say it's expanded

Dude coinheringaahing

emanresu A

@Dudecoinheringaahing Flagged it

Dude coinheringaahing

Post's been deleted anyway :P

emanresu A

How many does it take to get Q-banned?

DLosc

@emanresuA It's understandable. Someone's desperate to get help, they think they've found a place to get help, and the response is "No, we won't help you." They try another place, and the response is "No, we won't help you." That would be pretty frustrating.

emanresu A

9:16 PM

@DLosc True

Dude coinheringaahing

@DLosc I'd agree, if the comment was "No, we won't help you" Given the tone of my (auto-)comment, I disagree that response would ever be warranted

Aaron Miller

Dude coinheringaahing

@emanresuA There's no hard or fast limit, it depends on your recent Q asking record

emanresu A

Dude coinheringaahing

They don't reveal that, so that people can't try to circumvent it :P

See this

DLosc

9:22 PM

@Dudecoinheringaahing Warranted, no. Understandable, yes.

You need help. Place A says "Your question is bad (downvotes), we won't help unless you read this list of documents and do a bunch of stuff to fix it." But you need help, and you don't have time to read a bunch of how-tos on using a website. So you try Place B, and you include more of your code this time. Place B says "Your question is bad (downvotes), and we won't help you anyway, have you tried Place A?"

... All of which is the correct response to those two questions, but I don't think it will ever be well-received.

emanresu A

Think about it this way in terms of the people who answer the questions.

They have only so much time, and want to do as much as possible within that time

So they want well-written questions that clearly explain the problem.

Dude coinheringaahing

@DLosc We've had people respond with "Oh, sorry, I'll post there" after being informed

It takes nothing to be calm enough to respond with some basic politeness, so, no, I can't understand people reacting like that, even when frustrated

DLosc

@Dudecoinheringaahing Yeah, true, "I don't think it will ever be well-received" is putting it way to strongly.

Thomas Ward

i'm not fulent on the whole chain here, but... it's not unusual to get 'users' who are 'grumpy' with whatever's annoying them, and they want help and they take criticism / comments as 'direct attacks' and reacti accordingly

"i'm not sure it will be well received ever" is a tad aggressive and too strong thoguh i agree

Dude coinheringaahing

@ThomasWard Oh yeah, I know :P At times, I've been that user. And I'm incredibly embarrassed about how I've acted in those situations before. I still don't understand it, and I don't understand now why I acted like that

DLosc

9:30 PM

@Dudecoinheringaahing I disagree with "It takes nothing to... respond with some basic politeness." It takes something. Maybe very little. But sometimes you're at the end of your rope and you have nothing left to give. (In those situations, I'd suggest not posting anything rather than posting something rude, of course.)

Wheat Wizard

I think this user was more very confused than grumpy. But the two are not far apart.

DLosc

@ThomasWard That ^^ "end-of-the-rope" situation is what I was thinking about in my earlier comment.

Not literally meaning "ever"
