Are CMMCs (chat-mini-math-challenges) on-topic in TNB?

I seem to have posted one in the past...

caird coinheringaahing

I think they're fine

Mr. Xcoder

CMMC: (Chat-Mini-Math-Challenge) Prove that, among πe or π+e, at least one is irrational

betseg

If they weren't, you wouldn't have asked. ∎

Mr. Xcoder

16:45

Well, we have to admit that in TNB, anything is on topic. I mean look at the starboard... We were discussing linguistics a couple of days ago

betseg

CMC: golf in some spoken language

caird coinheringaahing

And we don't even need to mention this being on the starboard

Mr. Xcoder

@betseg Is the last character supposed to be a box or is it just my font?

caird coinheringaahing

@betseg English: "I'd rather not, if you don't mind" -> "no"

betseg

@Mr.Xcoder yes its a box, U+220E ∎ End of Proof

hey python

Mr. Xcoder

16:47

I find it fascinating that my CMMC can be solved, but neither of them specifically were proven irrational. But we do know for sure that at least one of them is

betseg

woah

we also dont know if either one is a normal number iirc?

Mr. Xcoder

“Normal” meaning “Algebraic”?

If that’s the case, the answer is Indeed, we don’t yet know for sure

betseg

> [...] a normal number is a real number whose infinite sequence of digits in every positive integer base b is distributed uniformly [...]

Mr. Xcoder

Oh. Then idk

betseg

they probably are but we dont know

Mr. Xcoder

16:51

Intuitively speaking, yes.

Question: How do I install the clang++ command on Fedora (27)?

Laikoni

17:54

@totallyhuman (:)<*>pure.(0-) Though it's still longer than the lambda.

@user202729 You can drop by Of Monads and Man if you want to learn more about point-free functions.

betseg

@HyperNeutrino is clang installed?

HyperNeutrino

apparnetly not :/

betseg

$ dnf install clang

HyperNeutrino

oh it was that easy

thanks :D

:D libreoffice now works thanks yay

betseg

you compiled LO?

Pavel

18:13

@HyperNeutrino was dnf install libreoffice not working?

Conor O'Brien

@PhiNotPi that's true. I never intended for such behaviour, and I think such behaviour is unnecessary for being TC. I agree that an implicit "push" counts as another instruction. Ensuring that the stack is either 1 when defining a label or 3 otherwise would remove this undesired behaviour.

betseg

@Pavel it took more than i want to admit to understand that sentence

Conor O'Brien

18:36

@PhiNotPi I have edited the answer and code accordingly.

HyperNeutrino

i installed it correctly but it was failing because clang++ was not found

@ConorO'Brien I think you accidentally deleted a big chunk of code?

label a -- goto a

whats so wrong about this? XD

Mr. Xcoder

It's a terrible language from nearly all points of view

PHP is like if someone took JavaScript and went "How can we make this worse?"

caird coinheringaahing

I'll shush :P

Mr. Xcoder

Good, 'cause we don't wanna spoil right?

@labela--gotoa What does '0' == 0 result in?

label a -- goto a

ummm... true?

caird coinheringaahing

Why?

Mr. Xcoder

In what other sane language would that be true?

caird coinheringaahing

JavaScript

label a -- goto a

but thtat'

Mr. Xcoder

18:44

@cairdcoinheringaahing ಠ_ಠ since when is JS sane?

label a -- goto a

but that's what === is for, right?

caird coinheringaahing

@Mr.Xcoder ¯\_(ツ)_/¯ Saner than PHP

Mr. Xcoder

Nope ಠ_ಠ That checks reference equality

label a -- goto a

For me PHP is very logical in this point of view

and more predictable

caird coinheringaahing

This. This is what is wrong with PHP.

label a -- goto a

18:45

I understand that function names and often their arguments are messed up, but...

@cairdcoinheringaahing umm, that's because PHP is put inside a <??> tag?

It's made to be inserted into HTML, right?

Mr. Xcoder

> There is no way to declare a variable. Variables that don’t exist are created with a null value when first used. There are no references. What PHP calls references are really aliases; there’s nothing that’s a step back, like Perl’s references, and there’s no pass-by-object identity like in Python.

mınxomaτ

FWIW I value the "get shit done" attitude of good PHP programmers. They have this in common with good C# or Go devs in my experience.

label a -- goto a

@Mr.Xcoder References are NEVER really needed.

caird coinheringaahing

How do you print things in PHP?

label a -- goto a

@cairdcoinheringaahing <? echo "Hello, World!" ?>

you wanted this?

It's a normal echo

caird coinheringaahing

18:48

ಠ_ಠ echo didn't work for me

label a -- goto a

how it ?didn't

Mr. Xcoder

\o/ I seem to be winning a "Best Of" category

Pavel

@labela--gotoa shouldn't there be a semicolon?

caird coinheringaahing

@Mr.Xcoder ಠ_ಠ And beating me

Mr. Xcoder

Ha. Haha

label a -- goto a

18:50

Looks like tio hasn't enabled the "short_tags" ini option, which is actually used 99% of the time

@Pavel, no. It's not required before ?>

@cairdcoinheringaahing Tio But since PHP7 it's never required

mınxomaτ

We don't speak of the horror before PHP7.

Pavel

@labela--gotoa TIO doesn't enable any flags by default ever. You can enable them yourself though.

label a -- goto a

@Pavel but that's a standard, it's on everywhere. Nobody leaves this to false!

Pavel

@labela--gotoa it's still the default

If you have to enable it on your machine, you have to enable it on TIO.

label a -- goto a

@Pavel still? Nowadays, you can't even set this to off!

Pavel

18:55

@labela--gotoa Obviously you can, since it's off on TIO.

label a -- goto a

@Pavel, because TIO uses outdated PHP version?!

caird coinheringaahing

You can request an update to PHP on TIO if there is a new version

label a -- goto a

oh, what the?

Conor O'Brien

@PhiNotPi what the heck? fixed now, how strange

Pavel

@labela--gotoa 7.1.13 instead of the current 7.2.1. 7.1.13 was January 4th of this year.

label a -- goto a

18:58

looks like tio doesn't use an outdated version. maybe i've imagined they've disabled it lol

Pavel

@cairdcoinheringaahing no you can't, because it's managed by dnf

label a -- goto a

I had a feeling it did.

sorry, buds xD

Erik the Outgolfer

uh, some of the header edits actually change the meaning of the post, the intention was to count in characters back in 2011, not bytes (cc @DJMcMayhem)

hi

Zacharý

What language is this guy's username in?

caird coinheringaahing

This is a public chatroom, label can see what you send :/

Erik the Outgolfer

hm, approaching people like that isn't very kind

Zacharý

Sorry, had no idea how to start the sentence.

caird coinheringaahing

19:24

What was label's previous username? would have been better

Zacharý

That assumed he had a previous username.

caird coinheringaahing

I think he used to be Soaku (if that's how it was spelt)? @labela--gotoa?

label a -- goto a

ah yeah

Zacharý

The question I want to ask is what language the username is in (programming language)

label a -- goto a

i was Soaku

polyglot, if you replace -- with ;

Zacharý

19:27

Ah, that makes sense

label a -- goto a

SE doesn't allow semicolons in nick, sadly

Erik the Outgolfer

well yeah because having a bunch of users called ;@@%!@&#* or (!*@&$&${}; can be very confusing :P

label a -- goto a

haha xD

Zacharý

Haha

Neil

19:43

@Pavel although a class itself can't have a sizeof of 0, it's still an empty class, and doesn't take up space in a subclass. of course, in your case, the subclass is still empty, so the sizeof is forced to 1 again.

Zacharý

The avatar of label a go-to a reminds me of Thomas Ward's for some reason

label a -- goto a

lol?

Neil

@MDXF It calls 0xEB 0xFE which is jmp -2. Since the short jump instruction is 2 bytes long, the -2 takes the IP back to the same instruction, and you get a hang.

label a -- goto a

@Zacharý the only similarity is color lol

Zacharý

We're still on this assembly/machine code question?

MD XF

19:53

@Neil Oh wow cool

Conor O'Brien

@mbomb007 they show up for me

mbomb007

Oh, nvm then

It's probably my web filter

Erik the Outgolfer

@mbomb007 try disabling ad blocker and ctrl-f5, it's you!

Conor O'Brien

I can confirm that web filters do affect that, tho, they don't show up at my school

ofc most filters block imgur :P

DJMcMayhem

19:56

@EriktheOutgolfer Oh. Well shoot

What should I do?

betseg

turkey blocks imgur

Erik the Outgolfer

turkey blocks imgur? are you sure it's not school? yes I know turkey has a lot of censorship unfortunately, but, well, VPN :P

betseg

even changing dns server works on most ISPs, but still, government ¯\_(ツ)_/¯

Erik the Outgolfer

uh, can government actually detect you're using imgur if you're using a VPN? of course you shouldn't use turkish VPN :P

betseg

i mean they dont do anything

but still, banning is the solution?

Erik the Outgolfer

20:02

@DJMcMayhem can't do anything now, but next time keep in mind that counting in bytes was established a bit later than 2011 ;)

DJMcMayhem

But does that mean using the word bytes in a header is wrong?

Erik the Outgolfer

uh, isn't it?

back then people counted in chars, so saying "bytes" would actually change the intended meaning

Zacharý

I just figured out there's a store named goats on the roof. And did @betseg change his profile picture?

betseg

yes!

Zacharý

Still an egg?

Erik the Outgolfer

uh, that looks more like a planet to me

Zacharý

I bets it's an eg. :P

betseg

i dont know if i want to star this or not

Zacharý

Star it if you're debating

Erik the Outgolfer

(the person who likes that extra star)

Zacharý

Wrong one?

Erik the Outgolfer

20:08

@betseg of course it's not the solution, it's not like people would think twitter or imgur are bad, malevolent sites anyway

betseg

oh they do

(in turkey)

Erik the Outgolfer

oh god they brainwash worse than Greece then, truth gotta be revealed sometime

The only way Greece brainwashes people is it's promises to pay back money, and that every vowel is an ee sound. /s

@MDXF Is intentional usage of comments to further obfuscate code allowed?

MD XF

@moonheart08 no it's specifically disallowed

moonheart08

Mk

MD XF

Your code may not contain any comments or unnecessary whitespace.

moonheart08

20:45

Time to abuse rust's multiline strings instead.

MD XF

@moonheart08 pretty sure that counts as a comment too, if they're like Python's multiline strings

moonheart08

They're not. Specifically intended for entering data

Doesn't work on it's own

MD XF

Ok

Like for example this still is a comment

moonheart08

Nope, i'll be using them for data, and making the code mess with itself.
