other way around

ASCII-only

@user202729 use quicksort at least (or pdqsort :P)

dzaima

@Riker I can never remember which way it is :p

@Downgoat I thought was (+) for functionized operator

What's the consensus on Community protected questions? Do we unprotect them, or just leave them?

Riker

9:23 PM

depends on the question

link?

caird coinheringaahing

As a general rule

Dennis

I usually just unprotect them.

Riker

likely yes

DJMcMayhem

Q: When should challenges be protected?

Users with 3,500 rep (or 15,000 if when we get a site-design) can protect challenges. This makes it so that users who have not earned 10 rep on the site can not answer. As a user with this privilege, I have no idea when it would be appropriate to use. This is because the idea of "protecting ques...

CMC: Given an array of 3 elements, square each

Add++, 22 bytes: D,f,@@@,c2 2 2B]a@BcB`

muddyfish

I've unprotected some community ones recently

dzaima

@cairdcoinheringaahing SOGL, 3 bytes: ⌡²¹

caird coinheringaahing

@dzaima Does SOGL not vectorise commands?

dzaima

@cairdcoinheringaahing nope :/

Adám

Blatant advertisement:

in APL, 7 hours ago, by Feeds

An informal APL learning session has been scheduled by Adam for Wednesday 17:30 UTC (18:30 UK, 19:30 DK) at https://chat.stackexchange.com/rooms/52405/apl

9:41 PM

@Adám :O They forgot the á!

dzaima

@cairdcoinheringaahing I would add that, but I'd have to rewrite pretty much every command as each pushes & pops everything by itself

caird coinheringaahing

@dzaima See, I don't know why I'm criticising your language, when mine takes 22 bytes (and hardcoding) to do the same task :P

dzaima

@cairdcoinheringaahing there is much to be criticised about SOGL :p

DJMcMayhem

@cairdcoinheringaahing {({({})({}[()])}{}<>)<>}<>

caird coinheringaahing

@DJMcMayhem Hmm, I'm going to guess... Jelly :P

DJMcMayhem

9:49 PM

Good guess!

Pavel

@cairdcoinheringaahing iirc, his name is actually just Adam, but he generally spells it with á because people keep pronouncing it wrong.

caird coinheringaahing

@Pavel His profile on Dyalog spells it with an á FWIW

Pavel

Yeah

¯\_(ツ)_/¯

caird coinheringaahing

I was just scrolling through the "Meet the Team" page on Dyalog APL and saw Marshall's description:

> since he used to work with J (programming language) and Jd (J database) and now works with Jay (Foad) and JD (John Daintree)

That must be really confusing :P

dzaima

CMC kolmogorov-complexity: 1 2 3 6 (any delimiter, or as array)

caird coinheringaahing

9:58 PM

@dzaima Add++, 12 bytes: D,f,*,1 2 3s

dzaima

@dzaima SOGL, 4 bytes. I have 4 bytes in APL too

Adám

@Pavel I sign with ´ but my passport says without. I don't really care, but it makes it easier to distinguish me among all the Adams.

@Pavel The ´ only works in a couple of languages, and even so, stress on penultimate syllable isn't really wrong.

caird coinheringaahing

@dzaima Jelly, 5 bytes: 3Rµ;S

dzaima

(I just realised that the 4 bytes APL is very obscure (well, it was the cause of the CMC))

@cairdcoinheringaahing what technique? I don't Jelly

DJMcMayhem

@dzaima ((((())())())[])

caird coinheringaahing

10:06 PM

@dzaima 3R => [1, 2, 3] then ;S appends the sum

dzaima

@cairdcoinheringaahing oh huh, that's a cool pattern (works from 1, 2 too). Doesn't hold further for the original sequence though

DJMcMayhem

Or (((((())())())){}) if you don't like []

caird coinheringaahing

@dzaima What's the sequence?

dzaima

@cairdcoinheringaahing that's ~~half~~ 9⁄10 of the CMC :p

caird coinheringaahing

ಠ_ಠ

dzaima

10:09 PM

The next term is 45 so there's that

caird coinheringaahing

ಠ_ಠ š isn't documented in SOGL

dzaima

@cairdcoinheringaahing the first 3 bytes are a compressed number anyway

and š isn't implemented anyway

caird coinheringaahing

So it doesn't calculate the sequence?

dzaima

@cairdcoinheringaahing nope. Too expensive for SOGL :p

caird coinheringaahing

@dzaima What is the code that calculates the sequence? I'm trying to learn SOGL

dzaima

10:13 PM

@cairdcoinheringaahing 1) it'd take me quite a while to write that as SOGLs missing 2 big built-ins for it and probably would end up > 30 bytes. 2) oh cool

caird coinheringaahing

@dzaima I notice you append →F to the end of code sometimes. What does that do?

As far as I can tell, → evaluates JS code

dzaima

@cairdcoinheringaahing mhm

@cairdcoinheringaahing usually the line before then ends with F, making it a function called F (which is then called later). (though I'm lazy and it's basically search and replace :p)

caird coinheringaahing

@dzaima So it calls a user-defined function?

dzaima

@cairdcoinheringaahing practically

caird coinheringaahing

Also, kudos for ′ meaning "is prime"

dzaima

10:18 PM

@cairdcoinheringaahing Well, it's really Is probably prime with the chance of error bigger than 2^1000 IIRC

ATaco

caird coinheringaahing

dzaima

also, since there are no new answers, I suspect noone thought of looking the sequence up on OEIS (or just didn't understand it :p)

caird coinheringaahing

@dzaima what does reverse add mean? Addition is commutative

dzaima

@cairdcoinheringaahing that's for strings & arrays (though what you've said is true for numbers .-.)

ATaco

10:21 PM

I should probably implement Unit Tests for Funky.

dzaima

should probably overload with something else

caird coinheringaahing

@dzaima So "abc" Κ "def" produces "abcfed"?

dzaima

@cairdcoinheringaahing no, defabc

caird coinheringaahing

Oh, prepend

dzaima

it's pretty much ;+

@cairdcoinheringaahing ..yeah, I can't name things :p

caird coinheringaahing

10:23 PM

dzaima

I should probably release some of my other SOGL tools I have (like the keyboard & replace compressor, probably some more I'm forgetting)

Also, I'm gonna disappear after ~4 minutes because parents [block wifi after 1:30]

caird coinheringaahing

@dzaima Same here. Parents really don;t understand the importance of the internet

dzaima

@cairdcoinheringaahing well, for me that's good because otherwise I stay up until like 8 (AM). Though it hasn't stopped me before :p

ATaco

It occurs to me it's possible to outright redefine operators in Funky.

caird coinheringaahing

@ATaco Ooh, how so? thinks of the chaos

ATaco

10:38 PM

Try it online!

caird coinheringaahing

@ATaco That would be brilliant for underhanded contests. Too bad they're banned

HyperNeutrino

... <- is scared of the implications of this lol

tries to add two numbers computer shuts down ._.

Then again, that will probably end up happening in Proton lol

ASCII-only

@ATaco hmm idea: funky/js interop

ATaco

Elaborate.

ASCII-only

be able to import js modules and stuff

ATaco

10:47 PM

That idea is horrifying.

ASCII-only

@ATaco why

ATaco

Right now, Funky is theoretically "safe", in that it cannot cause any harm to a computer.

Giving the ability to execute or cause the execution of NodeJS would circumvent this.

1 hour later…

ATaco

11:52 PM

CMC: Given a function, draw a graph of it in ASCII in the domain/range of 0<=x<=10 and 0<=y<=10.
