caird coinheringaahing

@Stephen yes it sjould

but @StephenS doesn't :(

Step Hen

@cairdcoinheringaahing that's because my last name's first initial doesn't matter

caird coinheringaahing

Should I change mine to "caird c"?

What's with the poster of this answer: codegolf.stackexchange.com/a/4245/68942 ?

Step Hen

@HyperNeutrino Some sort of weird account deletion probably

HyperNeutrino

00:41

The name is "CMS", which isn't in the form user\d+, but the flair is unlinked...

Probably, though AFAIK, it's reset to user<id>

Weird

Destructible Lemon

I was thinking about the koth that I had just proposed, and I was thinking about how to make it not have perfect information

HyperNeutrino

All on the same question?

Destructible Lemon

well actually I guess the worm order kind of does that

but not very well

Step Hen

@HyperNeutrino It got migrated

That's why

HyperNeutrino

OH RIGHT

thanks

Step Hen

00:43

All of them are users on SO who didn't have PPCG accounts

HyperNeutrino

that makes sense :))) lol

ASCII-only

@HyperNeutrino Migrated users, you can kinda tell from the question

HyperNeutrino

yup (though you were ninja'd lol). but yeah that makes sense. I should've noticed since I saw the migration notice lol

totallyhuman

01:03

Aw maaaaan

HyperNeutrino

wat

totallyhuman

Mego is on the opposite side of the meta vote

HyperNeutrino

rip

totallyhuman

Mm

But they also suggested making a new challenge

And that got downvoted too

HyperNeutrino

except I'm not sure which I agree with at this point

totallyhuman

01:05

Looks like we're probably stuck with the old question :/

HyperNeutrino

lol the 4th most downvoted meta question is Beta Decay's post about changing downvote behaviour

and lol the gif though: codegolf.meta.stackexchange.com/a/9455/68942

lol my tag badge progress on code-golf (the meta tag) is -5/100 score

tfw you see that a question's been singlehandedly deleted by a non-mod so you check the profile and it's a user with 1 rep, and then you realize that it's OP lol

totallyhuman

o0 the vote ratio on the meta is weird

HyperNeutrino

I love how my answer is just like "It is not a dupe" and then below Mego's is just like "Yes it is" lol

Step Hen

@totallyhuman Honestly I think the fact that it was hammered twice and reopened manually twice says that it's not, at least by the majority opinion

totallyhuman

Agreed

It's why I'm against hammers

Step Hen

01:19

@totallyhuman Nah, we need hammers, we just need to allow hammerers to choose not to hammer

totallyhuman

Disagreed :P

HyperNeutrino

thanks for the edit :P

@StepHen agreed

Step Hen

@totallyhuman Hammering is only for people who have experience. Usually, their unilateral decisions align with the community. It speeds up the process and allows askers to edit/fix a lot more quickly, as well as get crap closed sooner.

totallyhuman

The fact that 2 close votes and 5 reopen votes leaves a question closed is flawed

And also the hammerers would've definitely chosen to hammer it

Step Hen

@totallyhuman The fact that low-rep people can override more experience people is flawed by other reasoning :P

totallyhuman

01:22

No

HyperNeutrino

No, not really. You're assuming that close and reopen votes are essentially exact opposites, but what you're not noting is that one of the close votes is from a user with much more experience on this site, and all 5 of the reopen votes are from users with less experience. Also, 5 reopen votes??? And it's closed??? Or was the hammer after the 5 reopen votes?

Christopher

@HyperNeutrino Yeah idk how it even works

Step Hen

@HyperNeutrino Hammer close, 5 reopen votes, hammer close, 5 reopen votes, now a couple close votes

HyperNeutrino

maybe it should be locked until meta decides something... idk

anyway brb in a bit o/

Christopher

k ty

totallyhuman

@StepHen they cannot override

They can only be of equal or lesser significance

Step Hen

@totallyhuman Hammer -> 5 reopen, that's an override (veto) in my book

totallyhuman

Then I can't argue

Step Hen

At least by this definition: use one's authority to reject or cancel (a decision, view, etc.).

totallyhuman

01:29

5 > 1 /shrug

@StepHen and the low-rep users have authority over hammerers?!

Step Hen

@totallyhuman As a community, 5 lower-rep users have the authority to reject or cancel a hammer, I believe.

(unless I'm screwing something up)

totallyhuman

01:42

But that's a majority...

Step Hen

Is there a plugin for JetBrains (PyCharm) that supports Github markdown tables (the ones with -s and |s)

Phoenix

@StepHen Isn't that a default part of Markdown?

totallyhuman

Nope

HyperNeutrino

@Christopher: There's actually nothing wrong with the controller. It's because both of my bots contain one critical "kill switch", which is that it will always split if it has an empty hand. thus, one bot is just killing the larger hand and the other bot is splitting the smaller hand, until the larger bot can't hammer the smaller bot, in which case the smaller bot will attack the larger bot's smaller hand, also not hammering it. Then the larger bot can hammer the smaller bot. Etc, never ends.

or something like that

Christopher

@HyperNeutrino Oh lol

That is odd

HyperNeutrino

01:49

They occasionally finish... hm...

I recommend you run each game multiple times :P

Step Hen

@Phoenix I dunno, but my tables here (raw) show on Github and not on any of the markdown plugins

Phoenix

¯\_(ツ)_/¯

totallyhuman

tables are only in GFM

Step Hen

@totallyhuman That plugin didn't work either though

totallyhuman

you'd need html otherwise

Christopher

01:51

@HyperNeutrino But one is random.

totallyhuman

@StepHen weird

HyperNeutrino

@Christopher it does sometimes finish apparently.

Phoenix

Phoenix

Christopher

10k is not enough. :P

Step Hen

@Phoenix That one didn't work when I tried it, is my syntax wrong?

HyperNeutrino

Controller results for each game run 10 times (where A vs B is not B vs A because starting order): {'RandomBot': 0, 'Aggressor': 11, 'CautionBot': 33}

Phoenix

¯\_(ツ)_/¯¯\_(ツ)_/¯

Step Hen

@Phoenix It's not that important, thanks for trying, lemme focus on fixing my interpreter instead of being able to check my markdown without committing

@totallyhuman OK that works

HyperNeutrino

01:55

Default is left-align anyway so you can do this for all left:

blah|blah

Step Hen

@HyperNeutrino Github lets you do that

The plugins don't

HyperNeutrino

For the plugins you have to use the correct number of -s

Destructible Lemon

I had an idea...

what about a koth, that includes source modification

and the goal is for a program to output the highest ratio of unique fibonacci numbers/ other numbers, or some other formula

actually that doesn't make much sense :/

I had an idea for another koth, based on a genetic algorithm thing I saw

except the bots in this koth will have memory

so, the idea is that bots have a field of view

and they can only tell if an enemy is in the field of view

or a bullet is in the field of view, I'm not sure

Yes thats why I am going with the assumption a and n are coprime

if they are not coprime it is unsolvable (other than the trivial $x=0$)
