@lyxal when i saw this i instantly thought of the chinese character 人 lol

lyxal

I was wondering how long it'd take for comparisons to unicode characters lol

thejonymyster

i have done nothing but compare unicode characters for three days

@AidenChow what about lambda?

@chunes "Wolfram Language" being noticeably higher than "Mathematica" supports that, since answers using TIO would be under that name instead

Bubbler

Wolfram Language (Mathematica) would be parsed as Wolfram Language, yeah

@RadvylfPrograms encountered this yesterday :P

forest

01:11

@AidenChow Lies! That's the Japanese character 人!

Bubbler

No, that must be Korean jamo ㅅ :P

emanresu A

Nah, it’s obviously whatever this is: ⋏

forest

Or the logic symbol for AND: ∧

Unrelated String

@DLosc there's no label--ᶠ works over choice points and has no special relationship with constraint logic

@Seggan absolutely; it's very useful in and of itself, doubles as and over a list of booleans, and isn't necessarily the same as reduce by multiplication depending on how your reduce handles empty lists (product of an empty list should be 1)

att

01:30

@forest I think you mean it's the hanja character 人

Bubbler

To be precise, that's one of the characters common to CJK (Chinese simplified/traditional, Japanese kanji, Korean hanja)

it would be hilarious if it occupies four different codepoints in unicode

forest

I don't think it does.

emanresu A

@UnrelatedString Doubles as and over a list of anything

forest

But I wouldn't put that past the Unicode Consortium.

hyper-neutrino

i certainly hope they don't, it'd be such a waste of space to have every chinese and japanese character separate when there's at least a few thousand overlapping (i think) :P

Bubbler

01:39

It is indeed a CJK unified character

though there's a homoglyph in U+3xxx block and I have absolutely no idea what it is for

2xxx one is in the collection of "roots" of chinese characters

hyper-neutrino

compart.com/en/unicode/block/U+3190

Bubbler

That's very... err... selective? list of chars I guess lol

att

01:55

looks like they were used for annotating chinese for japanese reading

Neil

02:08

@UnrelatedString I use Minimum to and over a list of unsigned booleans

Bubbler

02:31

@UnrelatedString "all" of empty list of boolean is true anyway

and yeah, reduction by min is another good candidate (and it is what K does: min = boolean and)

Q: Can `a?b<c:b>c` be shortened in characters?

So I have the situation where I have one boolean value a and if that one is true and b<c I want it to end up as true, if a is false and b>c I want it to resolve as true as well. If b=c I want it to me always false, no matter the value b and c are both numbers. My best approach so far is a?b<c:b>c...

@lyxal calculating step goal

@AviFS around 6k i think

AviFS

wait, now i'm genuinely curious

what kind of goal is 6,013.4796, and way more sig figs

lyxal

It's a flat 6k

Just 6000

No decimals

AviFS

wait, yeah i just realized

it's just the rounding

318% would be <6000

and 319% would be >6000

AviFS

did the LYAL ever happen?

Aiden Chow

08:26

@AviFS no

AviFS

@lyxal also, hi!!!

@AidenChow this is such sadness; me no no understand

is this the first one that gets skipped?

Aiden Chow

@lyxal but 19183/6000 = 3.1971666..., it always round down?

AviFS

@AidenChow oh interesting, yeah i guess it truncates

not too uncommon, actually

but i'm not sure if there's a good reason they sometimes do that

is it just lazy coding?

lyxal

@AviFS hello there!

Notice anything different?

AviFS

@lyxal hello hello hello!

@lyxal you're room owner now, right?!

lyxal

Also I got some more data on the potential rounding method

AviFS

this is 'mazingful

congrats!!

~~make me one too~~

21039 is apparently 350% of 6000

AviFS

god damn

i give up on you se chat markup

i leave for two seconds and i already can't remember the wack markup

lyxal

Looks like Samsung truncates to 2 decimal places

Aiden Chow

@lyxal yeah probably truncated tbh

AviFS

08:33

is there a good reason some software truncates?

or is it just lazy coding

lyxal

21079 is 351% of 6k

So says Samsung

Aiden Chow

@AviFS idk, maybe its easier to implement truncating on whatever coding lang they are using?

or whatever they use to make the thing

lyxal

The language is Java btw

Because this is Android + WearOS3

had a challenge idea, not sure what to look up to see if its a dupe :P

given a list of integers, find out if there exists a pair of equal integers separated by n elements for all of 0<n<length-1

Adám

@thejonymyster +1

thejonymyster

im having trouble finding nontrivial examples :P

theres plenty with lists that arent just one integer repeated the entire length

e.g. [1, 1, 2, 1, 1] works

but i haven't found one yet that uses more than one number

i am doing it by hand though :P

another way to phrase the challenge: does the input list contain substrings of each length (up to the input length) such that the first element = the last element

(or phrased like that but better)

pxeger

@thejonymyster do you mean 0<n≤length-1?

thejonymyster

14:09

uhhh fenceposting

ill write it clearer in an actual challenge

srry im like at work :P

honestly, i might go for the substring definition or whatever

since i think it handles the length issue better? idk i'll be so so so careful and sandbox it a million times til its clear

Radvylf Programs

Using the 2022 Stack Overflow dev survey, I've estimated which languages are most worth learning, based on how much they'll be used in the future: gist.github.com/Radvylf/a5feacf0d70bf3bb7e4d5487060def0f

The top five are: Rust, TypeScript, Python, Go, and JavaScript

PyGamer0

i am currently trying to learn rust

lyxal

> Scala 4.26

:(

> APL 1.25

Even bigger :(

pxeger

> Crystal 0.93

PyGamer0

@lyxal @user you see that :P

Bubbler

14:20

@thejonymyster maybe check out langford sequences or skolem sequences

Radvylf Programs

Scala is surprisingly dreaded (50%), and doesn't have a large existing userbase to counter that like Java or JS

PyGamer0

@lyxal lets write v3 in rust :P

lyxal

@PyGamer0 haha no

Radvylf Programs

Not a bad idea

PyGamer0

@RadvylfPrograms probably because of the = after function definitions

idea: flax v3 in rust

lyxal

14:22

@RadvylfPrograms you kidding? It's horrible. We've already started with Scala, so it'd be pointless switching to rust now

Radvylf Programs

This of course doesn't take into account things other than language's expected growth; you might actually be looking to learn the opposite, a language that's somewhat niche or pays well since experienced devs are rare

PyGamer0

^^

user

@RadvylfPrograms Oof

Radvylf Programs

@lyxal Ah, didn't realize y'all had already started

PyGamer0

@RadvylfPrograms apl

lyxal

14:23

@RadvylfPrograms 7 months ago

Radvylf Programs

Oh wow I'm really behind on Vyxal news lol

user

@lyxal I mean, we could write it in Rust, since it compiles to WASM. We haven't even made that much progress in the Scala version

Radvylf Programs

Does Scala compile to WASM? Offline web-based interpreters are really neat.

PyGamer0

yeah rust also compiles to wasm

@RadvylfPrograms yes

Radvylf Programs

Oh nice

PyGamer0

14:23

i think

user

@RadvylfPrograms I may be biased but I've seen a lot of articles saying Scala has "arcane syntax" and a "steep learning curve," so people who don't know Scala may dread it a lot

Radvylf Programs

The "dreaded" category is for people who already use Scala regularly but don't plan to in the future

user

Ah okay

lyxal

@user but I kinda want to learn/use Scala because it looks neat and doesn't require 12 hours per PR to focus on compiler correctness

user

Scala is not as loved as I thought then lol

@lyxal lol yeah

Radvylf Programs

14:25

Loved = Used it regularly and want to continue to do so
Dreaded = Used it regularly and don't want to
Wanted = Didn't use it regularly and want to

Not great naming

lyxal

@user besides, Vyxal requires a bit of loose typing for overloads and other kinda wack stuff it does. Rust might not like some of the things we need to do

PyGamer0

@RadvylfPrograms bruh what is that naming

user

@RadvylfPrograms I don't think so. It compiles to JS and to native code though

Radvylf Programs

@user Could be people just moving away from the JVM or having to use it for work. If you absolutely love a language but don't want to use it regularly next year that still gets counted as you "dreading" it

user

Huh, odd

lyxal

14:27

for example, I love APL but wouldn't want to use it next year. That doesn't mean I don't want to use it eventually

PyGamer0

hm yeah true

user

It's possible Scala 3 is also driving people away. They added optional significant indentation which is pretty controversial and also haven't added macro annotations like in Scala 2

Radvylf Programs

Yeah, that's part of the issue with using those stats to estimate language's growth. I'm going to try to use the past years' surveys to include an "acceleration" component too, which will maybe be more accurate

user

Ooh

pxeger

and I'm not a betting man, but I don't reckon Solidity is a long-term good skill investment

PyGamer0

14:28

@RadvylfPrograms that would be good

rust would come first anyways :P

user

I'm surprised Ruby is so far down (loved: 49.99%). I thought it was a fairly popular language, at least within its user base

PyGamer0

yesterday, by PyGamer0

> Rust is on its seventh year as the most loved language with 87% of developers saying they want to continue using it.

lyxal

@RadvylfPrograms do you know of Jyxal/Myxal (our JVM ports of version 2) and Symvy (our attempt at making a CAS transpiler of sorts because frick sympy)? Because those are the only other things you'd have missed news wise

Wait hold up why are words like "is" and "so" not in the Jelly dictionary

Seems like those would add a lot of golfiness

Two characters is always shorter than a dictionary word, but not if you get the leading space free which you often need anyway

caird coinheringaahing

I'd imagine that sentences generally don't come up in compression challenges a lot

Radvylf Programs

Neither do words like "abets" or "juror" that are in the short dictionary

Common english words would still come up more often than really uncommon ones, so even if they're only needed rarely it's better than not having them

emanresu A

Fictional compression is hard

*Dictionary

caird coinheringaahing

It may be that compressing it using the standard ascii character compression comes out to be shorter

Radvylf Programs

Seems like a lot of really common words are missing. Must be a problem with the dictionary used.

Seggan

21:32

in Fig's case, chars can also have a space before them

so i removed all 1 and 2 letter words

Radvylf Programs

@cairdcoinheringaahing it takes about 24 bits to encode three characters individually, but only around 17 for a word

And it's not even just "all 2 letter words have been removed" or something like that, because there's plenty of uncommon 2 letter words and abbreviations, but also some longer words like "not" missing
