The Nineteenth Byte

yep, all good. i should've probably made it more obvious since it is the same as the length so i expected a lot of solutions, especially in golfing langs, to want to exclude it

@Jonah Your comment on my Sandbox post reminded me to run my example Jelly program through my analyser to look if the code/answer had been posted before. Couldn't find anything either, so I guess it really isn't a dupe

Either that, or the dupe is so old it doesn't have a Jelly answer

rak1507

can you post your challenge before I go to bed so I can fgitw please :P

caird coinheringaahing

You're in scotland right?

rak1507

yes

first day back at school tomorrow so I have to go to bed 'early' so I can wake up at 7

caird coinheringaahing

We're in the same timezone, so I'll be posting it at some point that you can FGITW it :P

I also have to get up early tomorrow :P

rak1507

maybe when Scotland becomes independent we'll move our timezone 10 minutes forward so we can say we're always ahead of the English ;)

caird coinheringaahing

9:39 PM

I'd 100% support that :P

rak1507

husk is a cool language I feel like it's similar to jelly in that noob golfers can do 'good' solutions but it's really hard to get shorter ones

need to use more advanced combinatory nonsense

caird coinheringaahing

@rak1507 The problem I mainly have with Husk solutions is exactly that :P

rak1507

what, the noob bit or the combinatory nonsense bit

yeah, no explanations actually explain the combinators (mine don't either)

caird coinheringaahing

I can follow them easily in explanations, then as soon as I try to do it myself, it ends up twice the length

Unrelated String

yep

rak1507

9:45 PM

haha yep same for me with jelly

I love being able to search for a builtin by its type signature though, that's very handy

caird coinheringaahing

I don't really understand the type signature notation, so it doesn't help :/

I can understand it if I try, but you can't FGITW by trying to understand things

rak1507

(a -> b) means takes an a and returns a b

I guess it's easier if you already know haskell :P

caird coinheringaahing

@rak1507 Yeah, I get that. The issue is things like (y -> y -> z) -> (x -> y) -> x -> x -> z

rak1507

takes a (function that takes two ys and returns a z), a (function that takes an x and returns a y), and two Xs, and returns a z

just from the type signature I can immediately tell what that's doing, it's applying the second function to both xs, and then applying the first function to that

func f g a b = f (g a) (g b)

this is equivalent to on, and that's probably what it's called

oh it's not called that but that's what it's doing I think

tio.run/##yygtzv7//9AS7XML/v//b/zfHAA

this is +⍥! in APL, apply factorial to both arguments and then add them

caird coinheringaahing

,f€g/ in Jelly I think

rak1507

9:53 PM

jelly needs over/on :(

add that to your derivative

and under

caird coinheringaahing

Or fgf} in Jelly

rak1507

what is that

caird coinheringaahing

@rak1507 That's a good idea

@rak1507 If f is a single byte, fgf} is the shorter version. Otherwise, ,f€g/ works

rak1507

ah

yeah definitely not as nice as f⍥g

caird coinheringaahing

My fork's running out of 1 byte atoms for quicks :(

Unrelated String

9:57 PM

:(

caird coinheringaahing

I have 9 single bytes for dyads and only 2 for quicks

And what I won't do is change the code page, break backwards-compatibility (mostly) or deviate from the naming conventions. At that point, I might as well make my own version of it and redesign the builtins from scratch

Unrelated String

which is something you're doing separately anyways, isn't it

caird coinheringaahing

"doing"

Unrelated String

"""doing"""

Peanut Butter is technically in dev, but I haven't edited it for a while

you're developing peanut butter in the sense that i'm developing perhaps

caird coinheringaahing

Yeah

I can either write an entire language in an afternoon (see Yggdrasil) or spend years on it

i'm trying to run a bash command with the contents of a file as the command line argument (so i can't do cmd < file); how should i do that for a multiline file?

cmd $(cat file) seems to work but only if the file doesn't have newlines

caird coinheringaahing

cmd $(cat "file")?

hyper-neutrino

doesn't seem to change anything ;-;

Unrelated String

...reminds me why haven't i moved Derived to record syntax in the last 4 days

rak1507

10:07 PM

cat file | xargs foo?

Unrelated String

probably because i was having second thoughts about the overall structure again

rak1507

idk if xargs handles newlines

hyper-neutrino

oh, i see. how does that work if i have other arguments?

like cmd a $(cat file.txt) b

rak1507

no idea :) use a real language

idk how to do anything much more complicated than cat file and ls in bash lol

Take a look at the list of tags on meta, specifically the excerpt for graphical-output:

> on the main site.

What the actual excerpt reads is:

> For questions related to the [graphical-output] tag on the main site.

Because for some reason, SE decided to strip specific words from the start of displayed excerpts ಠ_ಠ

o.O

How has this not been reported on Mother Meta and fixed already?

caird coinheringaahing

Because its status-bydesign

Lyxal

Yes I'm here now

^ just in case anyone was wondering if I was

user

Ok

@Lyxal I didn't know you were changing your username again, though. It still shows "Lyxal" for me, maybe you need to try editing it again?

Lyxal

@user are you taking your meds?

user

No

hyper-neutrino

10:27 PM

@Lyxal no, they're user, not "taking your meds"

caird coinheringaahing

@Lyxal nO, yOu'Re LyXaL

user

@cairdcoinheringaahing Mwahaha I ninja'd you already

caird coinheringaahing

@user Yeah, but I went for the lowest common denominator version of the joke so that Lyxal can understand :P

Lyxal

Well if y'all want to spiral into lyxalness that's fine with me

The more the merrier

user

@Lyxal Does the lyxalness ever end or do you become stable at some point?

hyper-neutrino

10:30 PM

I think you stay as yourself, you never become "stable at some point"

Lyxal

@user idk it doesn't apply to me.

Can't get lyxalitis if you already are Lyxal amiright? ⌍P

hyper-neutrino

mfw SIGSEGV but the debug output i put at the start of my main function isn't even showing up

user

This is why you don't use languages with one-letter names

rak1507

try flushing stdout

Lyxal

What language is it?

Q: Non-Hamming numbers

Hamming number (also known as regular number) is a number that evenly divides powers of 60. We already have a task to do something with it. This time we are going to do the opposite. I define non-Hamming number as in: \$n\$ is non-Hamming number if and only if it satisfies following two condition...

Y'all code golfing while I'm watching model trains running on reddit

What a nerd, not golfing :P

Model trains are kinda cool

rak1507

trains are cool but model planes are cooler

@cairdcoinheringaahing Um, I'm not sure if you got the memo, but the non-nerdy kind of golfing isn't the kind we do on this site
