I only subscribe to 175 down O_o

Zachary T

Is it usually like this?

Mendeleev

Yeah

Zachary T

So, how many people are students here?

Mendeleev

me

I'm getting my LL.B. while working at my $DAYJOB

Zachary T

21:07

I remember someone saying that a majority of PPCG is teenagers, that does not seem right for some reason.

mınxomaτ

A rather large part of active users is quite young.

Zachary T

At least where I'm from, activities like this aren't really popular. At all.

By anyone.

At all, not just people my age.

Mendeleev

afaik me (@Mendeleev), HyperNeutrino, Christopher Peart, Phoenix (AKA Pavel) are under 17

Can't remember anyone else

Oh yeah, downgoat

Zachary T

o_o.

Downgoat is my age or younger. LOL.

Q: Draw HyperNeutrino's benzene hegaxon icon in ASCII

ais523

21:10

huh, 20001 rep, nice to see it work out that exactly

Mendeleev

Wait, HyperNeutrino got their account back? Awesome!

ais523

(the first rep point doesn't actually mean anything because you have it by default and there's no way to get rid of it)

Zachary T

Well dang, how many of those people know APL?

Mendeleev

@ais523 *evil laughs*

ais523

oh, I just got upvoted

well, it was nice for a moment

HyperNeutrino

21:13

I was tempted to downvote you to get you to exactly 20k (actually I wasn't even slightly tempted to do that :P) :D

isaacg

@StewieGriffin I'd time it.

HyperNeutrino

except I think DVs are 2

ais523

huh, but for some reason I have 19991 rep on Meta

HyperNeutrino

caching

ais523

what a bizarre thing to cache :-P

you'd think it'd just use the same number as the main site

HyperNeutrino

21:14

That's what I heard, and it makes sense :P

@ais523 I know, right?

Zachary T

shouldiblamecaching.com

ais523

just pull it from the same cache

HyperNeutrino

@xnor Nice :) I like this challenge. Thanks! :D If I made it though, I'd have it take a truthy/falsy value and output either resonance structure based on that, but this challenge is nice. :)

xnor

@HyperNeutrino that's a nice idea, i regret not thinking of it

HyperNeutrino

trichoplax

21:15

@HyperNeutrino I think anyone (dupe hammer or not) should only vote if they are confident. If 5 people vote on a maybe the challenge gets closed without anyone strongly believing it is a duplicate.

HyperNeutrino

Looks like it's not caching's fault this time

Zachary T

Advice may be invalid due to caching.

trichoplax

If it's worth closing challenges just in case, then there's no need for someone with a dupe hammer to hold back, so either way I don't think it helps anyone to give them the option to water down their power

Downgoat

Question: is having lone code block useful in any way?

e.g.:

Mendeleev

@HyperNeutrino Switch to Arch

Downgoat

21:17

void f() {
    {
        randomCode()
    }
}

ais523

@Downgoat depends on the language; in Perl 5 a "bare block" is implemented as a 1-iteration loop, meaning it responds to loop control keywords

HyperNeutrino

@trichoplax That's a very good point. I suppose actually that having a hammer is good because it allows more experienced users to make decisions. Though I think it might be a nice idea to have the option to cast a variable amount of close votes; for example, a gold tag badge holder could choose to cast 4 CVs so that only one more person needs to agree. Not sure how well that would work out though.

Zachary T

SCOPING.

ais523

the fundamental problem is that close votes aren't actually votes

because the choices are "close" and "abstain", there's no "leave open" choice

(there's a "leave open" choice in review but all it does is cause the close votes to age faster)

HyperNeutrino

@ZacharyT Note: I just went into Inspect Element and edited the Yes to a No :P

DJMcMayhem

21:18

@ZacharyT I'm still technically a teenager (not for much longer though)

trichoplax

@HyperNeutrino I guess it might be worth making the system more complex if closing was irreversible, but since it's not I think keeping it simple is best

HyperNeutrino

@xnor I know, I'm just too good at thinking of challenges :)))) (lol just kidding :D) but yeah remind me to rotate my profile picture sometime.

Zachary T

@DJMcMayhem Let me guess, 19?

HyperNeutrino

@trichoplax True. Also, is it considered abuse for a person to close-hammer and then immediately reopen-hammer?

(to clear the CVs)

(I would assume so)

trichoplax

@HyperNeutrino I really don't know. I wouldn't expect a problem if they just made a mistake. If it's to stop other people's attention being drawn to it, that isn't much different than waiting for it to be closed first then opening it, since the people who saw it to close it the first time don't have a second close vote.

DJMcMayhem

21:21

@ZacharyT yeah

Impressive guess, considering I state that on my profile :P

HyperNeutrino

@trichoplax right, I forgot about that. Yes, then I think it might be considered some sort of abuse, or at least unadvisable behaviour.

Zachary T

I didn't use that. "But not for much longer though" was the tip-off.

trichoplax

If you see an example, flag it or raise it on meta. It's hard to make a general rule for something that hasn't been seen happening yet though.

HyperNeutrino

Yeah, true. I (fortunately) have not observed it, but I would flag it if I saw it.

I trust gold badge holders to be more responsible than that though :P

(and mods, even more so)

ais523

Q: Should dupehammer wielders use their powers to wipe obviously incorrect close-as-duplicate votes?

Occasionally, a user will cast a close-as-duplicate vote that's clearly incorrect. If that vote closes the question as duplicate, a gold tag badge user in a tag for the question ("dupehammer user") can then, as I understand it, unilaterally reopen it (thus overriding all the previous votes). My ...

support vote-to-close exact-duplicates dupehammer

Zachary T

21:24

What was a mod abusing that power or something?

HyperNeutrino

no

trichoplax

Both groups are expected to be responsible and have an interest in what's best for the community, but both groups are also human...

ais523

Stack Exchange is set up so as to maximise the chance of mods abusing their power by complete accident

HyperNeutrino

Yes, human error is always possible and will always happen. Getting a mod/the community to take a look at it wouldn't be harmful though.

Zachary T

But are they @totallyhuman ?

HyperNeutrino

21:25

trichoplax

If I make a joke about someone's name that doesn't require them to be pinged, I autocomplete then take the @ off the front to avoid irritating them. It's quick and easy :)

totallyhuman

Oh noes

HyperNeutrino

Or just do @trichoplax for example

No ping (I think) :D

totallyhuman

Why is my name becoming a joke? D:

HyperNeutrino

Because it consists of words

trichoplax

21:26

trichoplax

@ArtOfCode In the UK, we have two things called cookies. Small, crispy ones in packets (long shelf life), and large ones that have enough variation in cooking to be crunchy around the circumference but still soft (possibly gooey) near the centre.

HyperNeutrino

@WheatWizard You can if you feel like it, but you don't need to

ArtOfCode

Wheat Wizard

@DJMcMayhem Ok good

HyperNeutrino

Is it bad that "you should know better" has been said 7 times on TNB?

trichoplax

@ArtOfCode It's the big ones that shouldn't be all one or the other. They're big enough to exhibit the full delicious range from slightly underdone to slightly overdone all in one confection

ArtOfCode

21:36

@HyperNeutrino yep, clearly soft cookies are better

HyperNeutrino

And whose opinion was that? :P

Zachary T

Woah. Do sheep and cookies cause this much discussion

ArtOfCode

@trichoplax I'd rather mine were mostly if not entirely slightly underdone

overdone cookies... blegh

HyperNeutrino

sheep cookies

ArtOfCode

@HyperNeutrino mine :)

@HyperNeutrino :O

trichoplax

@ArtOfCode I must admit I like that if they're oatmeal and raisin ones

HyperNeutrino

ArtOfCode

@trichoplax ker-snap. Who could possibly dislike raisins in cookies?

let let = var

and if you want just usernames, let usernames=CHAT.RoomUsers.allPresent().toArray().map(x=>x.name)

@ZacharyT why?

Zachary T

It's pointless and kills compat with ES5

ArtOfCode

If ES5 compat is the only reason... yeah, I'm gonna use let.

It's a stricter var, and it's ES6.

CHAT.RoomUsers.allPresent().toArray().map(x=>'@'+x.name).join(' ') LOL

@PatrickRoberts no idea

brb making program

Can we assume that f(x) is unique for unique x?

wait that doesn't matter

Patrick Roberts

lol, if that was true, there'd never be a loop

HyperNeutrino

false

f(x) = 1-x, f(0) = 1, f(1) = 0

I'm gonna make a hello world

HyperNeutrino

f=lambda m,k:zip(*m)[1][zip(*m)[0].index(k)]
m,k=input()
s=f(m,k)
i=1
while s!=k:s=f(m,s);i+=1
print i

@LeakyNun Horribly long but ¯\_(ツ)_/¯ works
