The Nineteenth Byte

21:00

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

Shaggy

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

hyper-neutrino

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

Shaggy

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?

hyper-neutrino

interestingly, this only happens at the end of the program

Shaggy

21:06

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

A username

@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...

Shaggy

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?

A username

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

21:11

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

A username

@AaronMiller Yours is the last one standing...

Shaggy

@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

A username

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

Shaggy

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!

caird coinheringaahing

@Ausername Duck! :P

Redwolf Programs

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

A username

Ow.

Shaggy

Score!

A username

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

Aaron Miller

21:32

@Ausername Are you copying me? :p

A username

Partially

Aaron Miller

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

A username

Oh well

Nice

hyper-neutrino

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)

Shaggy

@Ausername Japt only! :p

hyper-neutrino

21:37

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)

Aaron Miller

@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.

A username

@Shaggy You'll crack it instantly then.

@AaronMiller Nice

caird coinheringaahing

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

hyper-neutrino

@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

N3buchadnezzar

21:39

@cairdcoinheringaahing Sounds like a cop out

hyper-neutrino

yeah

caird coinheringaahing

The rob is actually not too boring tbh :P

Aaron Miller

@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.

hyper-neutrino

yeah

caird coinheringaahing

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

hyper-neutrino

21:39

inb4 you didn't optimally compress

N3buchadnezzar

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

A username

Why would they?

hyper-neutrino

ah you didn't

caird coinheringaahing

@hyper-neutrino Optimality is for basic bitches :P

A username

Then you could just compare it to the optimal version

N3buchadnezzar

21:40

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

hyper-neutrino

yeah, optimality would've been too trivial

@N3buchadnezzar ?

N3buchadnezzar

There are a few sub optimal compression tools there

hyper-neutrino

fair

caird coinheringaahing

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

A username

OOh

hyper-neutrino

21:41

wait hold up

Shaggy

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

hyper-neutrino

this is smash printed

N3buchadnezzar

@Shaggy Make Japt popular

hyper-neutrino

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

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

Shaggy

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

hyper-neutrino

21:42

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

N3buchadnezzar

So you havent cracked it yet

Shaggy

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

hyper-neutrino

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

N3buchadnezzar

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

hyper-neutrino

removing 1 character will solve it but idk about changing one

caird coinheringaahing

21:44

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

hyper-neutrino

@N3buchadnezzar my name is “Rȷʠȧ¢ạ»

A username

@cairdcoinheringaahing Blame Makonede

caird coinheringaahing

@Ausername Why?

A username

They changed it to code-golf

caird coinheringaahing

Oh right

ಠ_ಠ

hyper-neutrino

21:46

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

hyper-neutrino

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?

hyper-neutrino

wait

thanks

caird coinheringaahing

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

A username

21:47

@RedwolfPrograms True

Shaggy

@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

Aaron Miller

@Shaggy Too late

caird coinheringaahing

@cairdcoinheringaahing I should spell his name right tbh

hyper-neutrino

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

A username

21:49

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

hyper-neutrino

fair enough

Redwolf Programs

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

hyper-neutrino

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

21:50

It was fun watching you overcomplicate it tho :P

hyper-neutrino

:(

guess i got properly nerd sniped :P

A username

Lol

Aaron Miller

@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)

hyper-neutrino

lol

@cairdcoinheringaahing ಠ_ಠ

caird coinheringaahing

21:55

:D

hyper-neutrino

i've been had

caird coinheringaahing

i have had you :P

A username

I've sleeped

Aaron Miller

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

A username

21:57

@AaronMiller I'm at 190

caird coinheringaahing

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

A username

for today

Ooh, repcap!

hyper-neutrino

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

hyper-neutrino

guess i gotta grind rep to get that now

A username

22:02

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

hyper-neutrino

same lol

caird coinheringaahing

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

A username

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

A username

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

caird coinheringaahing

22:06

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

A username

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

hyper-neutrino

@Ausername why not

and how did you find that

A username

I randomly look through meta a lot

And it's on your profile

hyper-neutrino

oh

caird coinheringaahing

22:09

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

11 plz

hyper-neutrino

can't sorry

caird coinheringaahing

wait what

how does Community have a listed answer?

A username

hyper-neutrino

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

caird coinheringaahing

22:11

But they have a diamond

And are user -1

A username

Hold on let me try something

hyper-neutrino

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

still looks unintended

caird coinheringaahing

Was that not posted by Martin originally?

hyper-neutrino

... perhaps

hold up

caird coinheringaahing

what

hyper-neutrino

22:12

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

hyper-neutrino

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

A username

@hyper-neutrino Nuke plz

I was trying to repro

but no

idk

caird coinheringaahing

Is that your sock?

A username

No, it's a guest account

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

but failed

caird coinheringaahing

22:17

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

A username

Oh sorry

So they posted the elections:

caird coinheringaahing

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

A username

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

How does that work?

caird coinheringaahing

Magic :P

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...

A username

@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

A username

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'...

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

Oh wait nvm

caird coinheringaahing

22:47

@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

Adám

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

A username

That's sad

@cairdcoinheringaahing Nope

caird coinheringaahing

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

Adám

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

A username

You got my upvote

hyper-neutrino

22:55

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

Adám

@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

hyper-neutrino

sorry, i meant the avatars all being ded

Adám

Oh. :-)

hyper-neutrino

22:56

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

A username

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

A username

Lol

hyper-neutrino

@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

A username

23:00

Oh

hyper-neutrino

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

hyper-neutrino

then how was I elected in the first place /hj

A username

@hyper-neutrino What if you step down?

hyper-neutrino

@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

23:02

@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

hyper-neutrino

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

^^

A username

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

hyper-neutrino

directly, only to mods

caird coinheringaahing

Used to be a 10k tool tho

hyper-neutrino

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

@cairdcoinheringaahing wait, what? all flags?

caird coinheringaahing

23:03

NAA only IIRC

hyper-neutrino

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

A username

hyper-neutrino

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

A username

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

caird coinheringaahing

23:04

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

A username

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...

A username

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

23:11

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?

Bubbler

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

Bubbler

69000 reviews... very unlikely :P

Redwolf Programs

23:14

But less likely than 6900 unnoticed questions? :p

Bubbler

daily cap is 20 reviews per queue or something I think

hyper-neutrino

mods don't have that <o/

caird coinheringaahing

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

hyper-neutrino

we also have like 5 reviews per day

caird coinheringaahing

@Bubbler 40

hyper-neutrino

23:14

sheriff doesn't say it can be awarded multiple times

caird coinheringaahing

I guess not :/

hyper-neutrino

brb gonna be a mod for 69 years to find out

caird coinheringaahing

I think the current record is ~10 years

Bubbler

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

caird coinheringaahing

@hyper-neutrino Try ^ :P

hyper-neutrino

23:16

lol

caird coinheringaahing

@cairdcoinheringaahing Michael Myers, 10 years and 6 days

hyper-neutrino

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

hyper-neutrino

oh my pfp was broken there

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