@Dennis exciting!

@Dennis Will score be upvotes or upvotes-downvotes?

@Pavel Usual pop con rules. I've edited the question to clarify.

my stats :(

looks like I'm not becoming an RO

I feel kind of bad for orlp. 0/-2 can't feel good.

4:34 AM

@Pavel I mean it's not personal, just that he's not that active probably

I think that's probably it

Yeah, haven't seen him much.

Is it just me or are there votes randomly disappearing.

No it's not just you

At least, not as active right now, when people who are active now are voting

4:35 AM

Oh, right.

Re Meta serial voting: during the "best of 2016" nominations I had my votes reversed three times

A friendly reminder: serial voting restrictions apply on meta as well, and may be triggered if you upvote too many nominations or downvote too many nominations in a short period of time. Make sure you check if any of your votes got reversed before the week is over. — Dennis ♦ 10 mins ago

@DJMcMayhem Wasn't that comment votes?

Yeah, but I upvoted the CW answers themselves

4:45 AM

most voters are gonna go by # chat messages

I go by a variety of reasons.

@PhiNotPi but you're higher than orlp

I hope it doesn't come to that though

@PhiNotPi Nah, most people will go by what they know of you from hanging around in TNB.

I agree. # of posts is mainly a tiebreaker for me

Though to be completely honest, I can't say that the results we're getting are at all surprising.

4:55 AM

BTW, hows tetris going @PhiNotPi ?

I would have happily ran if I were nominated.

I was not nominated.

@MistahFiggins It's really not, I've been busy with school.

@ATaco Everyone but Mego was self-nominated

@ATaco self nominations are allowed

@PhiNotPi Ditto

4:55 AM

I'm aware.

(ninjad)

plus side is that I made 100s on the two exams I had last week

But I wasn't going to run if no-one thought I was worthy of a nomination.

Well, by that logic, DJMcMayhem shouldn't have run, and he's winning now.

@ATaco nobody thinks I'm worthy of a nomination and I still ran

4:57 AM

And you're entitled to that, but I wasn't going to myself.

@PhiNotPi At least 3 people do

@Pavel it's perfectly valid to feel that way about yourself, even if you don't mind other users self nominating

TBH not really surprised by these results.

Besides, I have a job that I'm supposed to be doing.

I hope minxomat makes it most of all. The majority of the RO's are in US time zones. he'd fill in the gaps very nicely

5:01 AM

Yea

@DJMcMayhem are you asking me to remove vote for you then? ;)

Seems like it he'll make it.

(although Mego is a robot that doesn't sleep, so maybe it doesn't matter then)

IMO Mego deserved the RO position most of all.

@DJMcMayhem penguin live in antartica and there is is like day for like 6 months

5:04 AM

I honestly thought he was a RO a couple of weeks ago

Exactly, he's already managing everything to an extent.

Is NMP that slow or does it feel like more time has passed now that everyone's talking about it?

Took 54 minutes. It's slow.

Hmm.... there's about 1.5 months until mod elections.

Too early to start a campaign?

@PhiNotPi o_O I don't think those happen at guaranteed times

Once annually, although I admit there's little reason to expect SE to be on time regarding anything PPCG.

5:14 AM

@PhiNotPi gonna be honest, I don't feel you're active enough here to have likely chance of being elected >_>

You do contribute a lot of valuable things though so with more participation I may vote for you

@PhiNotPi They don't happen annually. Mod elections happen when activity spikes or a moderator retires.

@Dennis >_> I have been lied to

@Downgoat yeah I know <_<

Do they always happen when a mod retires? What if the other mods say they're fine?

It's ultimately up to the CMs.

If you guys wanted to, could you potentially hold a CM election at any point in time?

5:17 AM

Hmm, if you have only one mod and (s)he retires, it is guaranteed that all the mods say they're fine.

I wish we could hold a CM election

(CM = an SE staff member)

Speaking of elections, fun fact: I have the 2nd highest candidate score out of all of PPCG (only behind Martin)

I'm really proud of that

you could probably win with that

I'm glad that people think highly of me in regards to TNB. I make an effort to make good, positive contributions, help encourage others to do so also, and try to keep the amount of unwanted activity (i.e. noise) down.

@DJMcMayhem since 90% of users vote solely by candidate score it looks like you have good chance

A TC language/system can solve any problem (in the mathematical sense) that any other TC language/system can solve. There's a distinction between solving a problem and having some feature. Smallfuck is TC, but can't read from STDIN or write to STDOUT.

STDIN and STDOUT is different level

@Mego We've discussed this and decided against it. The vast majority of users that participate in chat (or would if the noise level were lower) will see either the pinned message here or the meta thread itself, and these are the only users that should participate in the election.

Anonymous

@Dennis Ok, fair enough. I agree with that logic.

5:43 AM

Not that we'll be able to keep it off hot meta posts anyway. >_>

Should we have not upvoted it?

Pointless. Answer upvotes also contribute to the hotness.

You could have pinned messages for every candidate, and held voting that way.

Actually, that sounds awful.

Agreed

The only way to avoid hotness would have been to vote via comments, which has its upsides and downsides.

5:49 AM

It probably would still have gotten hot

Anonymous

The main downside of the comment system (which the proposed star-voting system shares) is that approval voting is really not that great of a voting system. Range voting (which is what the current system is) is much better.

Yeah, agreed. I think it's as good as it could be.

And the main downside of answer voting is the serial voting reversal. Also, the full range is only available for users with at least 125 PPCG rep, but that could be a good thing or a bad thing.

Anonymous

125 PPCG rep is really easy to obtain - especially if you get the free 100 from the association bonus. We give out upvotes like candy. Without the assocation bonus, it would probably take a few days, which is not a downside here.

Anonymous

And there's nothing we can really do about the serial voting issue.

5:53 AM

I'd expect everyone who would be affected by the election to have 125 rep.

The voting reversal is really annoying, but I don't think there's a better option.

Aside from a dedicated chat room with I want X to become a RO and I do not want X to become a RO messages, with X's score being the difference of the star counts (which is kinda convoluted), I can't think of other options.

I want Jon Skeet to be RO.

Offsite voting is a possibility, but then we lose either accountability (only registered users can vote) or anonymity

Yup.

And both are pretty much deal breakers.

Surely cryptography has a solution!

How about we just make the voting process so complicated they nobody actually votes?

How about we just pit together the contenders in a game of BrainJoust

Or a good ol' fashioned CMC.

Well, we could hook up the signin system to the SE API and verify that the user a) has a PPCG account, and b) has at least 20 rep. But that's a pain.

Sure, but there has to be a certain level of trust with any system

I'm pretty sure the solution has to involve pasting vast bit strings into the chat.

CMC: Given a text that contains CMC: `SOMETHING` , find and execute the SOMETHING

Anonymous

If it's open-source and open-data, and only stores hashed API keys, it would be trivial to verify that your vote was recorded correctly and that the API key was not being stored, but nigh impossible to view others' votes.

I give it 10 minutes before it borks for no reason.

You see, I never get to use any of the things RProgN does well.

Like what?

Not a lot.

Because ~ is needed at the start of basically any golf'd program.

Can't you add that implicitly then?

Sometimes I don't want that.

6:11 AM

What does it do?

Zero Space Segment, the next word is executed individually.

So do is a function on its own, which is called. But ~do executes as d o

Although generally, for golfing, I need d o more than I need do

In a ZSS though, you can do 'do'gc, which will execute do, because it's "do" get_function call_function

Also alternatively, I could finish giving all functions a single byte solution, and remove the word functionality all together.

@Fatalize This is what I don't understand. It's apparently so hard for so many people.

TBH I just want to start a conversation

Start a conversation by suggesting a topic. That's seems to be how humans work.

If you are deliberately trying to talk without having anything to talk about, that certainly sounds like noise...

Of course you could always talk about noise, since that's a very popular topic nowadays.

1984 is a pretty good book, has anyone else read it?

Has N-think for N > 2 been studied?

@feersum What would triplethink be?

I don't know, I haven't studied it yet.

Doublethink is having two conflicting ideals, so naturally triplethink would be having three, I guess.

Conjecture: For every N-think, the person has N conflicting ideals/beliefs in their mind.

I guess Harry Potter movies sort of work, since "Harry Potter and the Deathly Hallows Part (1|2)" means the only possible index is -1, which has duplicates in "Sorceror's Stone"/"Goblet of Fire"/"Half-Blood Prince". But that feels pretty cheap.
