Q: Should new challenges on Codidact be posted into The Nineteenth Byte?

Codidact is a related network of sites to Stack Exchange, created in the aftermath of behaviour by Stack Exchange in late 2019, in an effort to create a better Q&A network. One of the sites in their network is Code Golf, where a large number of CGCC users have started to contribute. The site has ...

@emanresuA port of jelly be 4 bytes

Knight v2, 40 bytes (takes input 1-indexed): ;=nP;=b,=a@;W=n-EnT;=t a;=a b=b+@+,t,aDa

wait actually

36 bytes: ;=nP;=b,=a@;W=n-EnT=b+@+,=t a,=a bDa

bruh wait why am i even using a temporary var lol

33 bytes: ;=nP;=b,=a@;W=n-EnT=b+@+,a,=a bDa

shorter to print indefinitely but the website seems to get stuck if i try to do that

Steffan

you don't need the +@ lmao

you don't need to convert an array to an array

Aiden Chow

@Steffan shit u right, i was used to putting that there for numbers lol

itll be 31 bytes in that case

emanresu A

@Steffan smort

Steffan

for what numbers lol

Aiden Chow

2:54 AM

@Steffan i meant converting numbers to list of digits

just subconscious put the +@ there lol

Steffan

yeah but there's no number to convert to a list of digits. its arg is just a list

Aiden Chow

@Steffan ok ya ik that but like i just put it there out of habit anyways lol

Steffan

lol

@emanresuA you can actually get 3 bytes with Ṁ/mM flag

emanresu A

Ooh

Steffan

i feel like vectorized recursion should be one byte in a golflang

also you shouldn't need a lambda, so that would make flaggy 1 byte

Aiden Chow

2:58 AM

da hell is vectorized recursion

Steffan

recurse on each

Aiden Chow

@Steffan ohhh that makes more sense

Unrelated String

i feel like that's more mapped recursion
like vectorization carries the implication of implicit and known-depth

@cairdcoinheringaahing Maybe, yeah. It certainly feels familiar.

@cairdcoinheringaahing Wait, this is incorrect. Every sequence element after the first two should be a list containing exactly two lists.

Q: Should rust anonymous functions fully specify parameter types?

Context Rust does a lot of smart things to determine the types of variables. This is why you rarely need to define the types of a variable explicitly. Rust can search very far to find a type for a function. For example, this is invalid: let i; but this is: let i; i=5 These lines do not need to ...

Ostrich algorithm

In computer science, the ostrich algorithm is a strategy of ignoring potential problems on the basis that they may be exceedingly rare. It is named after the ostrich effect which is defined as "to stick one's head in the sand and pretend there is no problem". It is used when it is more cost-effective to allow the problem to occur than to attempt its prevention. == Use with deadlocks == This approach may be used in dealing with deadlocks in concurrent programming if they are believed to be very rare and the cost of detection or prevention is high. For example, if each PC deadlocks once per 10 years...

@mousetail This one

Adám

11:33 AM

@Fatalize Because J started as an ASCII transliteration of APL. APL has a mnemonic set of ⌽ reverse and ⍉ transpose. J kept the visual pairing, but had to compromise.

Number Basher

@Fatalize lol

mousetail

@Adám Wouldn't that make it a crewmate though?

Adám

@mousetail That's traditional.

mousetail

11:36 AM

There are a few normal S too

Adám

Yes, at the end of words and word-parts.

Long s

The long s ⟨ſ⟩, also known as the medial s or initial s, is an archaic form of the lowercase letter ⟨s⟩. It replaced the single s, or one or both of the letters s in a 'double s' sequence (e.g., "ſinfulneſs" for "sinfulness" and "poſſeſs" or "poſseſs" for "possess"—but never *"poſſeſſ"). The long s is the basis of the first half of the grapheme of the German alphabet ligature letter ⟨ß⟩, which is known as the Eszett. The modern ⟨s⟩ letterform is known as the 'short', 'terminal', or 'round' s. In typography, it is known as a type of swash letter, commonly referred to as a "swash s". == Rules... ==

Which of these language version selectors look better:

lyxal

second

Radvylf Programs

That's what I'm thinking, though I'm worried it might look weird for languages with a lot of implementations

mousetail

@RadvylfPrograms Why not align them all the way?

Radvylf Programs

@mousetail As in line up the versions?

mousetail

yes

Radvylf Programs

1:55 PM

Because they won't necessarily be using the same versioning schemes

E.g., Node.js's versions are totally different from V8's

mousetail

Also why does python only go up to 2.0

Radvylf Programs

Because that's where the good Python is /s

Nah I just typed in numbers that looked nice, and then added in the language name later

mousetail

It's actually really hard to find any info on python 1.x

lyxal

@RadvylfPrograms what's the maximum number of versions allowed?

mousetail

@RadvylfPrograms Not necessarily line up the same version numbers but use grid to they are paralel to a version, maybe two for long versions

lyxal

1:58 PM

@NumberBasher done

Radvylf Programs

@lyxal No hard maximum, but there's going to be guidelines. The number of versions you'd be expected to stay within reasonably is roughly proportional to how popular the language is and how large it is disk-wise

E.g., we don't need 40 different versions and implementations of Brain-flak, but 20 Pythons or 10 Vyxals would be fine

lyxal

@RadvylfPrograms so 103 releases of a language would be a no-no?

2:00 PM

@RadvylfPrograms would previous releases ever be deleted?

because that could be a problem if they aren't

@Seggan yes

Radvylf Programs

Speaking of LYAL, Trianguish was nominated a while back and I'm willing to teach it

@lyxal Whenever a new one's added, the person adding it (or bot) would be expected to get rid of any that are no longer needed

E.g., a new patch of the same minor version would probably just replace the old one

Or, maybe you'd want to keep around the most recent one, and replace the second most recent one, for bug-finding purposes

Maybe if the storage wasn't an issue, I could add an option (enabled by default) to show only the most important versions, and you could go in and see the whole list if you needed them all

I've only got 800 GB of storage right now, but maybe I'll hit my head really hard and drop $4k on 64 TB worth of SSDs and it won't be an issue :p

This UI doesn't look super good, but I can't think of a way to make the byte count and options dropdown look nice next to each other:

mousetail

@RadvylfPrograms Looks fine
