and the kind of language where it feels like this would really fit is something like rust where holy hell can it be nice to be able to shave off an extra function sometimes lol

Aitzaz Imtiaz

@Seggan All of them but one are open and have been received positively. She has even managed to get away with not using the Sandbox. This is rare for even a seasoned user. For these reasons I nominate him. [💀]

I am a he/him sir :D

worse, I am a 16 years old published kid

@AitzazImtiaz oops, sorry, i just reused the text for aira

Aitzaz Imtiaz

@Seggan thanks so much Seggan, but hehe... Aira kinda messed up with you and lyxal a lot i guess

lyxal

messed up?

I don't think she did

Seggan

yeah idk what lyxal has to do with this?

@DLosc Well 0 doesn't contain anything does it

Seggan

1 doesnt contain anything either

Rydwolf Programs

Hence it's also falsy

NaN is truthy because it is a container for a 22-bit payload

How does Rust encode Option<bool>? I know that Swift Optional<Bool> is 0=false, 1=true, 2=nil

Rydwolf Programs

Not sure. I know it optimizes it to a single byte tho

fn main() {
    println!("{}", std::mem::size_of::<bool>());
    println!("{}", std::mem::size_of::<Box<()>>());
    println!("{}", std::mem::size_of::<Option<()>>());
    println!("{}", std::mem::size_of::<Option<Box<()>>>());
    println!("{}", std::mem::size_of::<Option<bool>>());
}

Prints 1 8 1 8 1

Bbrk24

Also, guess what number this prints? enum E: Int { case x = 1 }; print(unsafeBitCast(E.x, to: Int.self))

I'll give you a hint, it's not 1

It's 0. No matter what you say in the = for the enum cases, Swift stores them as consecutive integers. The compiler generates a conversion function that uses either bitwise operators or a lookup table depending on what the source-level values are. unsafeBitCast circumvents this conversion function, of course.

sometimes it feels like every high-level C-like language stores enums in a different cursed way. Swift stores them consecutively and uses a lookup table for conversion; Java makes them full-fledged static objects of a type with a private constructor; ...

~~Rabbit's going to make them lists of functions which return the member values~~

Oh yeah and then there's TypeScript. TypeScript emits a bidirectional map of value <=> name so that you can look up enum cases by name at runtime

"use strict";
var E;
(function (E) {
    E[E["x"] = 0] = "x";
    E[E["y"] = 1] = "y";
})(E || (E = {}));
console.log(E['x']);

@Seggan surely though in ternary you would want your tryte to have a number of trits that's a power of 3

@DLosc it is in set theory, since 0 is actually represented by the empty set

Bbrk24

@Ginger I know you're joking but one time I implemented arrays as functions: github.com/zackradisic/aussieplusplus/issues/…

Ginger

no, I'm not Jo King, I'm Ginger

we are very different

Jo King

need to start banning that word

say that you're just joshing instead

Bbrk24

my bad

Seggan

01:29

@Neil yes of course

that was an example though

@Bbrk24 (its a joke btw, dont feel too bad)

@Bbrk24 i love this kind of stuff

Bbrk24

I recently discovered that I have gcc on my computer in addition to clang and msvc… so I have all three major C/C++ compilers

(The gcc I have is Arduino gcc, which is AVR-only. I can’t produce a file that I can run.)

@JoKing BRB, changing my name to Josh I. Ng

@Neil Good point

If someone just turned around to me and said "You're not laughing, you're caird", and their explanation was "Laugh Ing is a person living in Vladivostok", I'd have so many more questions :P

So, anyone here live in Vladivostok?

guys i just get my first good question badge!!

@emanresuA da hell where is that lol

Vladivostok

Vladivostok ( VLAD-iv-OST-ok; Russian: Владивосто́к, IPA: [vlədʲɪvɐˈstok] (listen); Chinese: 海参崴, Pinyin: hǎishēnwǎi) is the largest city and the administrative center of Primorsky Krai, Russia. The city is located around the Golden Horn Bay on the Sea of Japan, covering an area of 331.16 square kilometers (127.86 square miles), with a population of 600,871 residents as of 2021. Vladivostok is the second-largest city in the Far Eastern Federal District, as well as the Russian Far East, after Khabarovsk. Shortly after the signing of the Treaty of Aigun, the city was founded on July 2, 1860 as a...

@emanresuA huh interesting... why that city specifically...

@emanresuA well ok then...

weird choice but ok

SetBang 1

SetBang 2

> SetBang (or S∈tBang) is a language based on the foundation of all mathematics: set theory.

Maybe of interest to those of us working on Complement. I'll cross-post there.

I haven't read it yet, though. And probably won't tonight.

Also, maybe, of interest. From the same guy. He makes analogies between the axioms of ZFC and some computational primitives, and briefly explores ZFC through that lens. Also, haven't read.

(By the way, this is Michael O Church, who is evidently quite a figure in the tech world. It's quite a rabbit hole I fell into tonight. Explore at your own risk!)

@AidenChow It was the first city I thought of. It was almost 3am at the time
