9:00 PM

why the hell does ‛ not consume the next two characters???

it pushes the string and then also runs the next two characters as commands??? what

is this a known issue already

@hyper-neutrino Or is it your interpreter? I had so much unexpected behaviour when building my Japt interpreter.

@Shaggy it would be lyxal's interpreter, mine just interfaces with it

Ah, OK

Redwolf Programs

@Ausername Are we allowed to add input validation to our cops, within the bounds of what the challenge guarantees input will be?

interestingly, this only happens at the end of the program

9:06 PM

I ended up doing the same with mine, just pulling in ETH's base files.

@RedwolfPrograms For my one? Sure, although you can just say that input has to be within those bounds, you don't have to enforce it...

@AaronMiller So close...

C&R idea: Cops: polyglot in at least 2 languages that provides solutions to at least 2 existing challenges, Robbers: add an additional language that provides a solution to a challenge the cop's version doesn't. Have we had it? Does it sound good?

Maybe?

Redwolf Programs

That sounds cool

Unrelated String

doesn't feel very c&r-y without there being a certain degree of "intended crack" built in to the cop posts, but i also don't have the most experience with c&r and there could be some real interesting stuff coming out of it with language pairs that shouldn't be conducive to that kind of thing

Redwolf Programs

9:11 PM

My reading of it was that there was still an intended solution

@AaronMiller Yours is the last one standing...

@RedwolfPrograms Yeah, as with all C&R challenges, there should only be one intended solution.

Maybe if the cops provided the challenge that they expected the robbers' answers to be a solution to?

Or the language that they expect to he added?

Unrelated String

hmm

i'm having a hard time thinking of which wouild be better to prescribe too

probably challenge

I've got another one, coming soon...

Dealer's choice of which to provide might add a bit of intrigue. I can flesh that out in the Sandbox, though.

@Ausername If it's Vyxal, I'm throwing my phone at you!

5

9:23 PM

Sorry

@Shaggy * Threatens A username with a free phone *

Try vyxal.hyper-neutrino.xyz

Might be better for mobile

caird coinheringaahing

@Shaggy I suppose that's better than throwing a beer at them :P

idk

@cairdcoinheringaahing That would be criminal wastage!

Well, here y'all go!

caird coinheringaahing

@Ausername Duck! :P

Redwolf Programs

Oh I didn't even realize there was a new CnR lol

Ow.

Score!

Ok, ok, I'll get you a JS one in a bit.

9:32 PM

@Ausername Are you copying me? :p

Partially

Hmm… Now that I think about it, should I have left it for someone else, since I knew the trick?

Oh well

Nice

well, it's too late now, but morning compresses as øø and occupational as ẋẋ

found these by locally recompressing by hand before i remembered there's an element to do that

unfortunately i didn't know the exact trick off the top of my head (though using the cursed k-digraph thing that i did know about and extending that to other digraphs would've been a good start)

@Ausername Japt only! :p

9:37 PM

hm I should post an answer that requires precise knowledge of either jelly or vyxal's compression algorithms (probably the former as the latter is pretty trivial, and even then the former is quite easy to go from compressed to decompressed even without sss, and there's both a python program from user202729 and my online tool to do the other way)

@Ausername I saw “morning” and “occupational”, and I thought, “that looks like dictionary compressed strings”, so I ran it through øD, saw the repeated characters and \` and then knew that the last half would have to be pretty much unchanged, then realized that the D “just happened” to have a string in front of it, and then put 2 and 2 together.

@Shaggy You'll crack it instantly then.

@AaronMiller Nice

caird coinheringaahing

@hyper-neutrino Imagine not doing a boring compression cop :P

@AaronMiller see would've been nice if i remembered that element existed and didn't waste time compressing by hand

@cairdcoinheringaahing :bruh:

well

i am going to go recompress my name by hand to figure it out, if nobody gets it before i am done then i will snipe it :p

caird coinheringaahing

My compression is too well known for a good cop :P

9:39 PM

@cairdcoinheringaahing Sounds like a cop out

yeah

caird coinheringaahing

The rob is actually not too boring tbh :P

@hyper-neutrino Yeah, it’s pretty nice. I’ve never actually used the compression commands in a submission, but I’ve used them plenty for making submissions.

yeah

caird coinheringaahing

It's by no means interesting, but it's not that boring :P

9:39 PM

inb4 you didn't optimally compress

So you can beat a compression into submission, nice to know=)

Why would they?

ah you didn't

caird coinheringaahing

@hyper-neutrino Optimality is for basic bitches :P

Then you could just compare it to the optimal version

9:40 PM

@hyper-neutrino They could have used one of the ones from the Jelly golfing tips thread

yeah, optimality would've been too trivial

@N3buchadnezzar ?

There are a few sub optimal compression tools there

fair

caird coinheringaahing

“Rȷʠȧ¢ạ» is the optimal hyper compression :P

OOh

9:41 PM

wait hold up

@Ausername Therein lies the challenge: find something I can't crack.

this is smash printed

@Shaggy Make Japt popular

i'm stupid. didn't notice the string delimiters

wait no it isn't, because double nilads don't smash print in a nilad

@N3buchadnezzar That's my sole purpose here. I'm failing miserably.

9:42 PM

ooh this should be easy now that i've found my approach angle. unless it fails, ofc

So you havent cracked it yet

I genuinely don't understand why more people don't use it.

no i haven't because it isn't just the trivial "compress this string and compare which character is different", that would be much too boring

you have to suboptimally compress it exactly the right way which now that i think about it i am not sure i necessarily know how to do either :P

Have you tried just reversing the string and running it through the standard compressor?

removing 1 character will solve it but idk about changing one

caird coinheringaahing

9:44 PM

wait, I earned the code-challenge tag badge yesterday, but apparently I don't have it, and it's on 94/100 score O.o

@N3buchadnezzar my name is “Rȷʠȧ¢ạ»

@cairdcoinheringaahing Blame Makonede

caird coinheringaahing

@Ausername Why?

They changed it to code-golf

caird coinheringaahing

Oh right

ಠ_ಠ

9:46 PM

ok never mind i apologize for saying this is not hard :p

i could brute force it but i'm sure there's a more obvious solution

caird coinheringaahing

Bruh just read my mind

oh yeah i forgot my diamond lets me do that

Redwolf Programs

In an SBCS language, can't this be brute forced in linear time?

wait

thanks

caird coinheringaahing

@cairdcoinheringaahing Philippe's response. TBH, I wasn't really expecting a response

9:47 PM

@RedwolfPrograms True

@RedwolfPrograms "Only" 256 characters in the codepage, go for it!

Redwolf Programs

This seems like a very boring CnR, any answer will either be trivially brute forceable or take advantage of some weird unicode + halting problem thing that makes it very tedious and/or cryptographically difficult

@Shaggy Too late

caird coinheringaahing

@cairdcoinheringaahing I should spell his name right tbh

dammit aaron ninja'd me with a probably more intended solution

i just swapped the close quote for a random character not in the codepage, which feels like a cheat :p

9:49 PM

JS for you

Redwolf Programs

@Shaggy That's 256 * number of bytes, even if you gave the program a whole second to complete you could brute force an answer in an hour

caird coinheringaahing

@hyper-neutrino I don't even think that's a valid program tbh

fair enough

Redwolf Programs

@RedwolfPrograms And since this is about kolmos, you could probably get away with milliseconds

just my first thought cuz redwolf said smth about it being an sbcs and i was like... what if it isn't

mfw got too caught up in trying to reverse engineer how you compressed it instead of just swapping the quote characters for some trivial alterations lol

caird coinheringaahing

9:50 PM

It was fun watching you overcomplicate it tho :P

:(

guess i got properly nerd sniped :P

Lol

@hyper-neutrino I just looked to see what the first compressed string was, then remembered the one unique jelly mechanic I know (not because jelly’s not unique; I just don’t know jelly), which is that you can separate literals with “, tried it out, and was extremely surprised that I got the answer before anyone else (like I said, I don’t know jelly)

caird coinheringaahing

Added an explanation (cc @hyper-neutrino :P)

lol

@cairdcoinheringaahing ಠ_ಠ

caird coinheringaahing

9:55 PM

:D

i've been had

caird coinheringaahing

i have had you :P

I've sleeped

I’ve gained 100 rep today, exclusively from that one CnR

caird coinheringaahing

You've been talking about the compression systems so much, I figured that a suboptimal compression would guarantee you'd get into your own head :P

9:57 PM

@AaronMiller I'm at 190

caird coinheringaahing

CnRs are all about confusing the robbers IMO, and mind games are great at that :P

for today

Ooh, repcap!

13 mins ago, by caird coinheringaahing

Bruh just read my mind

guess you have done that :p

caird coinheringaahing

@hyper-neutrino Yeah, it's not a mod tool, it's a privilege you get when you're between 39300 and 39400 rep exactly :P

guess i gotta grind rep to get that now

10:02 PM

@hyper-neutrino I honestly just tried random things until I got something syntactically valid. Nice crack!

same lol

caird coinheringaahing

Ooh, I might repcap for the third day in a row, but over 2 sites :P

I repcapped yesterday and today.

10 times total

C&Rs are fun like that

caird coinheringaahing

I think 3 days in a row in my record, I may have done 4 once

Jon Skeet's record is... A long, long time.

caird coinheringaahing

10:06 PM

If Legendary was "Repcap on 150 consecutive days", and you could get it multiple times, I think he'd have it ~14 times

Yes

> they are all either human beings with feelings or bots that Jon Skeet made when he was bored, and we don't want to offend either.

Hyper, why?

caird coinheringaahing

@cairdcoinheringaahing That's ~2000 consecutive days capping

@Ausername why not

and how did you find that

I randomly look through meta a lot

And it's on your profile

user image

oh

caird coinheringaahing

10:09 PM

@hyper-neutrino codegolf.meta.stackexchange.com/users/-1/community

11 plz

can't sorry

caird coinheringaahing

wait what

how does Community have a listed answer?

user image

and in the rev history, they are named anon: codegolf.meta.stackexchange.com/posts/5057/revisions

Not them

ninjad

caird coinheringaahing

10:11 PM

But they have a diamond

And are user -1

Hold on let me try something

idk... do CW answers from deleted users get weird treatment?

still looks unintended

caird coinheringaahing

Was that not posted by Martin originally?

... perhaps

hold up

caird coinheringaahing

what

10:12 PM

martin's meta profile has his identicon but not main - i think their "fix" broke everything

but martin's other answer is fine

caird coinheringaahing

They're still fixing it

status-planned

nuke plz

the timeline says it was answered by Community and two comments from anon were posted (and deleted) - those should be martin's standard "+1 from me" posts

@hyper-neutrino Nuke plz

I was trying to repro

but no

idk

caird coinheringaahing

Is that your sock?

No, it's a guest account

I was seeing if you could sneak a diamond into your 'Name'

but failed

caird coinheringaahing

10:17 PM

I could've told you that - you can't

Oh sorry

So they posted the elections:

user image

caird coinheringaahing

Yeah, Community posts elections and a couple of other automated stuff

Wait, it's the same user, but with different profile stuff?

How does that work?

caird coinheringaahing

Magic :P

status-everythingisonfire

10:22 PM

Do you mean in Vyxal? Because that's accurate.

Redwolf Programs

Maybe the aliens are here and they're using some sort of cosmic ray laser to mess with SE's datacenters :p

caird coinheringaahing

@hyper-neutrino This isn't network wide

The bug is coming from inside the house

Hm..

caird coinheringaahing

Writing up a bug report now

@user sus

10:27 PM

0

Q: Why does Community have an answer here?

Community looks to be very buggy today. However, this appears to be specific to this site - I've been unable to repro this on other sites or their metas. It appears as though Community has an answer on our meta: Do we really want LaTeX/MathJax (right now)?. I've checked a few other metas on the n...

support bug meta users

@hyper-neutrino Do you know when there's another election?

caird coinheringaahing

Whenever the mods think they need additional hands on the team

Although I think the CMs "force" an election if a site goes too long without one, but I don't know how long "too long" is

Why is it much easier to get 'Nice question' than 'Popular question', but much harder to get 'Good Question' than 'Notable question'?

All but three of my questions have 'Nice Question', but ~half have 'Popular Question'...

user image

Does anyone know anything about this? The link's dead...

Oh wait nvm

caird coinheringaahing

10:47 PM

@hyper-neutrino Looks like a lot of the old guard got hit by the Gravatar bug :P

Bill is no longer a lizard :(

Peter Taylor's been reverted, Howard's has changed, Geobits is no longer a downvote, ugoren, miles, El'endia, CJY and a few more have also been hit

Funnily enough, gnibbler's fine :P

@cairdcoinheringaahing Thanks for this. I've also put in my own answer.

That's sad

@cairdcoinheringaahing Nope

caird coinheringaahing

@Adám Good luck, I doubt that we'll ever get a straight answer to that

Doesn't hurt to try. Not like they can fire me…

You got my upvote

10:55 PM

yeah... let's just hope SE can properly revert this

@hyper-neutrino What do you mean by "revert this"?

Redwolf Programs

Even if for some reason they lost the data, SEDE should still have an old copy in the worst case scenario

caird coinheringaahing

The profile picture bug

sorry, i meant the avatars all being ded

Oh. :-)

10:56 PM

not your answer - they can't revert that at this point but they can at least come clean about it as you said

they should've tried it on windows phone.SE first to see if there were any bugs

even if it destroyed everything nobody would notice until the next time someone makes a joke about windows phone.SE

Agreed

Redwolf Programs

They really need a sandbox.se

Make it so it's publically available too, for testing stuff

caird coinheringaahing

Just rebrand windowsphone.SE :P

Lol

@Ausername to reiterate what caird said, basically it's whenever it's needed. specifically, whether mods are needed is largely determined by how flags are being handled on the site

11:00 PM

Oh

so, even if one of our mods steps down right now, it is unlikely to immediately cause an election, as our site's flag handling time is extremely low and we don't often have pending flags

caird coinheringaahing

Or, we hold one every time the mods' golfing abilities drop below the acceptable standard :P

then how was I elected in the first place /hj

@hyper-neutrino What if you step down?

@Ausername just because the vast majority of flags are handled by me doesn't mean that the site wouldn't be fine without me

caird coinheringaahing

11:02 PM

@Ausername Then the CMs would discuss with the other 3 mods whether they want a new mod, just the same as if any of the team stepped down

i get to the flags quite quickly most of the time and so the other three don't get much to handle, but if I stepped down, then they'd see those flags and be able to handle them

^^

Do flags just go to mods, or 10k+ users like with chat?

directly, only to mods

caird coinheringaahing

Used to be a 10k tool tho

indirectly, certain flags kick it into the review queue which you can see at varying rep levels

@cairdcoinheringaahing wait, what? all flags?

caird coinheringaahing

11:03 PM

NAA only IIRC

this is why i've repeatedly said to not use NAA flags on invalid answers

it puts it into the review queue and actually witholds the flag from me for an hour unless i manually go to the dashboard and check "ignore time threshold"

caird coinheringaahing

@Ausername Elections are done entirely on whether the existing mod team thinks the site could do with new moderators. Whether that's because a mod steps down, the site increases in activity, or the mods become just a bit too busy IRL, that's really the only thing that triggers an election

user image

and especially if the flagger doesn't even bother to leave a comment explaining why it's invalid, those reviews often get dismissed

I've asked about this so many times but I still don't get it.

caird coinheringaahing

11:04 PM

@Ausername Don't worry about it, it's a know bug

Looks like we're both quite good at prematurely pressing enter.

caird coinheringaahing

For example, the last election was triggered because DJ asked for it

A: Sandbox for Proposed Challenges

Make me some puzzles So, a while ago on Puzzling, I posted this. It basically had a whole bunch of equations that were wrong, and when you figured out how much they were wrong by, and transformed 1-26 into A-z, it yielded the phrase ALLWRONG. Your challenge is to take a string of letters as input...

I wonder if any user has or has had at some point 4 gold badges, 20 silver and 69 bronze exactly...

caird coinheringaahing

@Ausername Probably. The challenge is to get 69 gold, 4 silver, 20 bronze

Redwolf Programs

11:11 PM

I don't think that's possible

Are there any gold badges you can earn multiple times that don't also give you bronze and silver variants?

Socratic, maybe

except that you need to be lucky enough to get all your questions unnoticed

caird coinheringaahing

Yeah, if you ask 6900 well-received questions

Redwolf Programs

Maybe you could do 69000 reviews in a single queue

caird coinheringaahing

@RedwolfPrograms Sheriff :P

69000 reviews... very unlikely :P

Redwolf Programs

11:14 PM

But less likely than 6900 unnoticed questions? :p

daily cap is 20 reviews per queue or something I think

mods don't have that <o/

caird coinheringaahing

@RedwolfPrograms You could just do it in 4 queues, and have the silver badges

we also have like 5 reviews per day

caird coinheringaahing

@Bubbler 40

11:14 PM

sheriff doesn't say it can be awarded multiple times

caird coinheringaahing

I guess not :/

brb gonna be a mod for 69 years to find out

caird coinheringaahing

I think the current record is ~10 years

Maybe stepping down and getting re-elected can give double Sheriff?

caird coinheringaahing

@hyper-neutrino Try ^ :P

11:16 PM

lol

caird coinheringaahing

@cairdcoinheringaahing Michael Myers, 10 years and 6 days

journeyman should have that on SU if it could be awarded multiple times but they don't

wait never mind, journeyman did not resign on SU

and they resigned from MSE too quickly to get sheriff and only got it after reinstatement

caird coinheringaahing

Neo did, but only has 1 badge

oh my pfp was broken there

well, i'm just gonna reupload my picture outside of gravatar and push that ಠ_ಠ

Posting soon. Any feedback? (Also others)
