CMC: Given a Boolean list and a count, return the index (0 or 1-based) of the first occurrence of a run of the given count of falses. If no run of that length is found, return a recognisable value e.g. -1 or the list length or for 1-based indexing: 0 or 1+length, or null etc.

Radical of an integer math code-golf The radical of an integer (written as \$rad(n)\$) is defined as the multiplication of all prime numbers which divide it.

@Adám Scala, too many bytes: _ sliding _ indexWhere(_.forall(!_))

rak1507

15:31

Scala is pretty cool I like the _s

the default.

@Adám Gaia, 2 bytes: ċI (Try it online!) (these are the built-ins "create n zeroes" and "find first occurence") (I don't know why is swapping the inputs twice in the beginning necessary)

Adám

@user What is !?

the default.

I don't know scala, but I think it's probably the "not" operator

Adám

@thedefault. Ah, Gaia is 1-indexed?

@thedefault. Ah, makes sense. so _.forall(!_) means "not any".

the default.

@Adám it seems to be (I've never used any indexing in Gaia before, so I didn't know until today)

user

15:50

@Adám That's right

The underscores are placeholders, so if you expanded them, it'd be (a, b) => a.sliding(b).indexWhere(c => c.forall(d => !d))

user

16:05

@rak1507 You should try out Scala, it's really fun! Since it's the language of the month right now, I can give you a bounty if you use it for a code golf answer :)

rak1507

I might do!

user

Great! By the way, has anyone nominated an APL dialect as LotM yet?

Adám

16:29

@user I think that by now, APL is popular enough here that it can't be nominated for LotM.

user

@Adám Fair enough.

rak1507

well husk was lotm and it is fairly popular

Adám

16:52

Husk:1102, Brachylog:959, Brain-Flak:802, MATL:2,075, QBasic:317, Japt:2,592, Self-modifying Brainfuck:39, Forth:540, Rust:402, APL:3882

rak1507

17:26

fair point

Adám

@user Obviously, I wouldn't mind, so you can nominate APL if you want. I don't think specifying a specific dialect is necessary.

caird coinheringaahing

@Adám Are the numbers for the 2018 languages from 2018 or today?

Adám

@cairdcoinheringaahing Today, so after they were featured.

caird coinheringaahing

So they were probably much lower when first nominated

I get 1382 for Japt and 1674 for MATL counting before they were LOTM

Adám

It'd make for an interesting meta post: "The effect of LotM"

Jonah

20:01

I'm looking for a python lib or function that can do the same as itertools.product, but with the constraint that every returned element has only unique items. That is, uniq_prod([1,2], [1,3]) should return [(1, 3), (2, 1), (2, 3)]. And I want it be efficient, in that it should not construct the full list and then filter. Doesn't have to be golfy, can use numpy, etc. Asking here because just because of the number of python experts.

rak1507

stackoverflow.com/questions/19744542/… ?

Jonah

@rak1507 yeah saw that. from the accepted answer: "you generally have to either post-process the itertools result sequence, or "roll your own".". i was hoping someone here might know of another way saving me from rolling my own.

rak1507

by copy pasting their answer

Jonah

that just might work :)

caird coinheringaahing

@Jonah Because product returns a generator, using a yield statement in uniq_prod shouldn't decrease the efficiency too drastically I think

Jonah

20:11

@cairdcoinheringaahing Thanks.

surprised cartesian product is a whole 2 bytes tbh

seems like it would be quite a common thing

caird coinheringaahing

@rak1507 p returns the cartesian product of 2 arrays, but if we need to do it for arbitrary arrays, we need the internal cartesian product builtin Œp

rak1507

Ah fair enough

user

@Jonah I'm not a python expert, but does this work? I can't comment on the efficiency, though, you may prefer a generator of some sort. Perhaps a set would also be better for lookups.

do you think anyone would do my latin homework for me if I said to do it in the fewest number of bytes possible? :P

user

21:55

They might, but in Jelly instead of Latin :)

@rak1507 I promise you your professor will give you a good grade on every assignment if you tell them this: Vide hic et paulo Pedicabo ego canis tuis te currere si non dabis mihi bonum gradus (I used Google Translate, so I don't know if it's retained its meaning).

rak1507

The reverse translation is 'See it here and a little to be running if you shall not give to fuck me, get good grades, I will return you to your dog,'

(according to google translate)

Latin google translate is notoriously terrible

user

Erm...the original was "Look here, you little bugger, I'll run over your dog if you don't give me a good grade."

caird coinheringaahing

I know where the "fuck me" came from then :P

user

I should have checked before replying :\.

rak1507

Yeah, I picked out 'canis' 'currere' and 'non dabis mihi bonum gradus' but didn't bother with the rest

Back to the Cicero

user

22:06

You weren't kidding about it being terrible. A few iterations of English -> Latin -> English and I now have "Looking for your dog if he does not, and the man to whom you want to run, little'm to me, give me, and I do not get good grades." At least it doesn't have any profanity left now.

rak1507

lmao

yeah, it really is

It doesn't recognise verb conjugations etc as far as I know

So translating latin can be a right pain

user

Ah, that's too bad.

I've found it rather handy for French and Spanish.

rak1507

Yeah, it doesn't help that the subject is obscure enough that often there aren't really many great online resources

@Lyxal If we're talking tea with milk (and not green tea or whatever), then definitely tea. In the summer, though, iced coffee is way better.

If it's not strong, there's no point in drinking it.

@Lyxal Tolerable, yes. Enjoyable? Not so much.

@rak1507 Then why drink milk, which is gotten using methods that lead to so many cows' deaths?

It's like buying products from sweatshops.

rak1507

@Lyxal By hating milk, you're hating the way humans have fed their infants for millenia, implicitly condemning the survival of the human race

user

I do not support cow milk.

Lyxal

@rak1507 I don't hate milk I'm just saying you're wrong for hating water ;D

rak1507

@user If the cows didn't want to be farmed, they shouldn't have made their milk so delicious. I don't know what they were thinking to be honest, rookie error

user

Actually, milk is delicious so their young stay around. I don't think they were counting on humans drinking it too.

rak1507

22:39

Well they should have thought of that

(seriously though, factory farming is bad I agree)

user

Also, a lot of people are lactose intolerant. If humans were meant to drink milk, most of us would not be.

Meanwhile, apparently no efforts have been made to limit the availability of this potentially dangerous chemical compound."
