@lyxal I'm surprised you of all people were one of today's unlucky 10,000

lyxal

03:00

@UnrelatedString why would I be the kind of person to know about pilk?

Unrelated String

It feels like it's been a meme for a while

lyxal

July 2020 was when I was doing practice for that hsc thing I mentioned the other day :p

rydwolf

03:19

Went on my first "official" date

Unrelated String

Whoa

What happened

rydwolf

if I read the mood right neither of us really wanted to be there but had a mild amount of fun as acquaintances lmao

Unrelated String

lmaoooo

rydwolf

It did involve climbing through a window to get into a locked building

Any hangout with me on CMU's campus will eventually degenerate into trespassing

Unrelated String

Why does that only barely surprise me

Unrelated String

03:40

It always trips me up how >> and <$ are in the Prelude but $> isn't and << doesn't even exist (probably owing to being redundant with <*)

(even though >> is also redundant with *> :P)

rydwolf

04:06

Okay never mind he said he had a great time and wants to hang out again so I just have no awareness lmao

Unrelated String

nice (?)

3 hours later…

RubenVerg

06:54

@UnrelatedString oh what <$ is in prelude? I could've been using that instead of importing $> all the time

1 hour later…

Neil

08:06

I comment on a PR, and it says my comment will be made in an hour's time. I think Github doesn't understand DST

mousetail 'he-him'

08:17

Same for me, but in my country DST ended several days ago

Neil

08:48

yeah, but Github might have ended DST today

4 hours later…

Seggan

13:13

uff

i missed out on an hour of sleep due to forgetting DST exists

@rydwolf what on earth is pilk

lyxal

don't google it

Seggan

too late

lyxal

please for the love of all things don't

No

gosh dang it

Seggan

sounds disgusting

lyxal

13:36

@Seggan lost?

that only happens when it starts

last I checked y'all in the northern hemisphere do dst when we aren't and vice versa

and we're doing it down here right now

at this very minute

DST is a thing that people are doing

I do not agree that it should be the case yet here we are

an extra hour into the future despite the fact we can already see 10 hours into tomorrow

Seggan

@lyxal nope the time went back

lyxal

So really you didn't lose any time at all

You got to be a morning person for free :p

Giving you access to pretty much every coffee shop because they're only ever open in the morning

Very annoying for when you're more of an afternoon person

Unrelated String

14:32

@Seggan But I gained one...?

Actually one and a half because I fucked up and THOUGHT I'd lose one so I set my alarm forward 40 minutes

all I know is it was uncharacteristically bright out when I got up and the microwave clock said it was 9 when I got up at 8

Seggan

14:55

@UnrelatedString i meant i woke up at my normal time, which is now an hour behind so i couldve spent that extra hour sleeping

its actually fortunate that i woke up earlier since i need to do some music editing for choir today

Unrelated String

Ooh, nice

att

if you stay up through the time change do you still gain an hour

The Empty String Photographer

Out of context quote of the day: "Since most of us aren't giving Mo Farah a run for this money, isn’t plain old water hydrating enough?"

Apoorva Shukla is spreading 100 rep bounties in every SE site using the trust initial. How to find out which site trusted it?

I can find stackexchange.com/users/19786124/apoorva-shukla?tab=accounts but it doesn't help much

Neil

16:42

well, they only have two yearling badges, so the other sites must be newer

Unrelated String

17:09

@l4m2 stackexchange.com/users/19786124/apoorva-shukla

Probably Movies and TV

l4m2

It obtained Association Bonus on movies.stackexchange.com/users/85345/… on Oct 13, Do Association give to self?

Unrelated String

Oh

Yeah I don't think it does no

mousetail 'he-him'

18:09

@l4m2 Yes, I'm pretty sure it does

3 hours later…

ATaco

21:01

I love being outgolfed in my own language, feels good

Like, someone actually tried it, incredible

mousetail 'he-him'

Sometimes I purposefully leave some low hanging fruit as bait

Unrelated String

Smart

mousetail 'he-him'

21:16

Good thing Rust generates so many warnings for every random thing

lyxal

@ATaco it's all fun and games until it becomes a regular occurrence :p

ATaco

Don't worry, nothing I write will ever see mass adoption

Bbrk24

@mousetail'he-him' Is there supposed to be code there? I just see an empty code box and a warning telling me I have to log in to edit it

mousetail 'he-him'

Sorry, there is not supposed to be code there, just low score

No need for eprintln!

CMC Write code that produces two distinct warnings

ATaco

git clone {any of my codebases}

Bbrk24

21:33

@mousetail'he-him' print(1 as? String)

mousetail 'he-him'

@Bbrk24 what lang?

Bbrk24

In Swift, this gives warning: cast from 'Int' to unrelated type 'String' always fails and warning: expression implicitly coerced from 'String?' to 'Any'

The latter warning happens whenever you pass a value of type T? to a function that takes Any instead of Any?

And actually the second space there isn't needed, it can be print(1 as?String)

@mousetail'he-him' Python 3.12, 7 bytes: 2or'\k'

produces SyntaxWarning: invalid decimal literal and SyntaxWarning: invalid escape sequence '\k'

mousetail 'he-him'

The best I could come up with in Rust is {let mut i=0;} which warns that the variable is unused and that it doesn't need to be mutable

Unrelated String

@emanresuA Ooh, interesting that that's only a SyntaxWarning in 3.12 when it's a full-blown Error in 3.11

emanresu A

21:46

Wait huh

Actually, better one: 0is 1 (SyntaxWarning: invalid decimal literal and SyntaxWarning: "is" with 'int' literal. Did you mean "=="?)

Bbrk24

I only get the latter (3.10)

Unrelated String

I'm guessing they tweaked the parser to be able to parse that, and downgraded the error to a warning to not lose either the slight added functionality or it still being Discouraged™️ (and remind people it's not backwards-compatible)

@emanresuA ooooh, nice

Bbrk24

and your first example doesn't warn at all

emanresu A

again , this gives warnings on 3.12

Unrelated String

@emanresuA ...Weirdly this one does work the same way for me on 3.11 as it does for you

Wait fuck I typoed the first one LMAO

Yeah the first one warns me about the literal but doesn't say anything about the escape

mousetail 'he-him'

21:50

Oh I actually ran into the error when using a \k escape code when golfing recently, cost me a byte. Guess I should have just updated python

emanresu A

Hm, interesting.

Unrelated String

I typed 20r'\k' originally :P

emanresu A

IIRC there are specific cases where 2or syntax is ambiguous with e.g. for comprehensions

Unrelated String

@mousetail'he-him' Doesn't error or warn on 3.11

emanresu A

still a sad day for golfers

Unrelated String

21:52

And I swear I remember invalid escapes also not warning on older versions

mousetail 'he-him'

They used to be fine

Unrelated String

since you can sometimes save on backslashes and/or the r prefix for regex stuff that way sometimes

mousetail 'he-him'

Actually I think I did %k format string, not \k. I misremembered

I think that used to just warn

lyxal

@mousetail'he-him' exactly 2 or >= 2?

emanresu A

According to SO it's a DeprecationWarning in <3.12 and a SyntaxWarning in 3.12+

mousetail 'he-him'

21:53

@lyxal Ideally exactly two distinct, though you can have more of the same type

Unrelated String

I'm not seeing the warning for '\A' either...???

Maybe it's a REPL thing

It does warn on ATO's 3.12, and it doesn't warn on TIO's 3.7

att

N[,]

Unrelated String

22:10

...I'm kinda shocked the implicit nulls are warning-worthy
from how many answers I've seen them in and not bothered to actually run and look at, I kind of assumed it was just completely intentional and idiomatic functionality :P

if for no other reason than that most other languages I'm familiar with just refuse to parse something like that at all

att

22:22

i think it's popular to allow trailing commas these days

so newline-separated lists have nicer diffs

lyxal

@mousetail'he-him' vyxal 3.5 (in progress branch), several megabytes [proof: github.com/Vyxal/Vyxal/actions/runs/11629774401/job/…

Unrelated String

@att Yeah that much is for sure

lyxal

The main code (not the testing stuff) produces unused private member warnings and unused import warnings

Unrelated String

Leading commas, though, not so much

att

yeah

I think it's reasonable to warn on those implicit nulls, it's not usually something people do on purpose

it definitely is intentional though reference.wolfram.com/language/ref/Null.html#17782

Unrelated String

22:27

Ahh

So it's a "hey just making sure you actually wanted to do that but no shade" kind of warning rather than a "please don't do that but we won't stop you" kind of warning

emanresu A

Isn't there also that cursed mathematica golf trick where you can use implicit null as a variable in some situations

Wolfram Language (Mathematica) Plot3D[Sin@Norm@{,y},{,-4,4},{y,-4,4}] Mostly the obvious implementation, although Norm is a short way to access the square root of the sum of squares, and I did remember to save 2 bytes by letting one of the variables be the invisible Nulls before the commas (not ...

att

yep

fun fact, you can also override built-ins in the same way tio.run/##y00syUjNTSzJTE78/…

Unrelated String

Oh

That's kinda cursed and kinda elegant

Maybe I'm just too Prolog-brained but Mathematica's approach to that kind of stuff has always seemed nice from the outsider perspective of having never tried to actually use it

Q: Create a grid as close to a square as possible

Create a function or program that makes a grid as close to an square as possible You will be given an integer N as input, whole numbers (1,2,3,25, etc) The output must be a perfect rectangular grid of N letters as close to a square as possible The (wannabe)square must consist of one of the the ...

code-golf ascii-art geometry grid

I don't understand why this was closed

it seems clear enough to me, other than the bonuses.

Unrelated String

22:42

I think it's "clear enough" that "as close to a square as possible" means "with a minimal maximum side length", but I'm still VTC as needs details/clarity because the wording around the bonuses is a mess and we really don't need people necro'ing old challenges with pointless bonuses. — Unrelated String 7 hours ago

att

@UnrelatedString uhh what do you mean with respect to prolog

Unrelated String

I admit that I'm slightly biased for reasons that fall outside actual closure criteria, namely feeling that the challenge is overall dated, but the spec is still really hard to pick apart and the bonuses affect the "core" in that regard too

@att Is Mathematica's homoiconicity not kinda like Prolog's?

noodle person

I'm thinking of just editing it to remove the bonus for patterns. I have a solution I just finished with and I had no problem understanding the task, so I disagree with it being closed with details/clarity, at least.

Unrelated String

I swear I remember Mathematica having some way to decompose a term like Prolog's =..

@noodleperson And that is what making a new challenge is for :P

att

my only experience with prolog is trying it a little bit when it was lotm

(i barely remember anything atp)

Unrelated String

22:45

I like the idea of it and if anything it deserves better than being trapped in this weird legacy cruft

noodle person

@UnrelatedString I guess I can just post a new one, sure. I'll sandbox it to avoid it meeting the same fate as its predecessor :P

Unrelated String

That's the spirit :D

@att tio.run/##KyjKz8lP1y0uz/z/…

...lmao I didn't even notice this gem

1 X amongst all O's isnt really a pattern is it? We're all smart people. — Martijn Sep 25, 2014 at 12:38

att

uh what is =..

noodle person

@UnrelatedString Lol

Do you think I should make the program take a character as input, or just use some arbitrary constant character?

Unrelated String

@att The decomposing a term operator :P

@noodleperson I'm leaning arbitrary constant character

noodle person

22:50

That was my first thought

att

oh

so like head(body...) -> [head, body...]

Unrelated String

Yep

noodle person

I'll let an array of some number in that shape be allowed too. Though at some point, it does become basically just "find the factor pair with the least difference"

there's Construct going the other way but I don't think there's something that does exactly that

lyxal

22:55

truly an long ox moment

Unrelated String

@att Interesting. Well, at least =.. goes both ways so what I said was more or less correct even if what I was actually thinking wasn't :þ

att

{a,b,c} is the same as List[a,b,c] so I don't think bidirectionality is possible on this side

but yeah everything being an expression is nice

emanresu A

@UnrelatedString So it does actually have requirements on what a "pattern" is (horizontally/vertically symmetrical up to inversion) but that does allow you to get away with a lot of abuse e.g. my vyxal

But yeah, although it could fairly easily be edited to clear it up, I'm not sure there's much point

@noodleperson Ah I see

Unrelated String

23:36

@att real

@att Prolog lists are actually also headed terms--though it's not quite the same, since they're effectively cons cells of '[|]'(Head, Tail) rather than having all elements at the same depth

When I said "goes both ways" I meant T =.. [h,a,b] works just as well as h(a,b) =.. L

oh
