Since I can no longer unprotect questions, I tried to flag a couple days ago that codegolf.stackexchange.com/q/55422 needs to be, but no one has reacted :(

DJMcMayhem

@ØrjanJohansen Sorry about that, it's taken care of now

Ørjan Johansen

Thanks

@H.PWiz i don't think I've seen that one either, i'll check it against my list

I just realised I hadn't been receiving any notifications about rep changes in the top bar for about the last week. I saw my most recent answer had an upvote, but I didn't have a +10, so I checked and I had about 10 things that hadn't showed up

i just thought no-one was upvoting my answers :(

Here's a challenge idea: Given an balanced or unbalanced string of parens, append left parens to the left and right parens to the right until it's balanced (or output how many you'd need of each)

Not sure if a) this has been done before, or b) this would actually work to rebalance arbitrary unbalanced parens

Jo King

Just one set of parens? Else that would end up being ( = 1 and ) = -1, then sum and get the absolute value

oh wait, something like )(, hmm

Sherlock9

Typing at random )()((()()())()()))

Which I think just needs two left parens

Actually, yeah, I think you have it right. CMC then: Output the number of parens (left and right) to rebalance a string of unbalanced parens

@Sherlock9 Perl 6, 23 bytes

Adám

@JoKing @Sherlock9 Shouldn't it give two numbers per input?

@Sherlock9 APL (Dyalog Extended), 17 bytes ')('⍧''⎕R''⍣≡

Jo King

oh, i thought it would be the total

In that case, 31 bytes

Adám

@Sherlock9 If the total, 8 bytes in QuadR: Try it online!

Sherlock9

07:20

Actually considering that it's only going to be either left parens or right parens, I suppose one number would work

Well, whichever format works best, but it should somehow show when left parens are needed versus when right ones are

Maybe converting to 1s and -1s is the best idea

Jo King

08:48

no, you can have both, for example)( has one on either side

Neil

@Sherlock9 Retina 0.8.2, 27 bytes

Sherlock9

@JoKing Oh, I hadn't considered that! That's for correcting me

A test case that considers that then: )()((()()())()()))( should return 2 1 (or 1 2, depending)

@H.PWiz that's one i haven't seen anywhere (convergence rate is log(4) ≈ 0.6 digits per term)

H.PWiz

It's remarkably similar to this series. Which is very slowly converging

I saw it in the list of formulae at the back of "pi unleashed"

primo

x_{n-1} = x_n * A016754_n / A068379_n

In JavaScript, you can have the following three functions: n=>2**+n, n=>2*+n, n=>2+n which return 2ⁿ, 2n and 2+n, and are also character deletions, in fact of only a single byte each time.

@DJMcMayhem Can mods also move comment chains on challenges to chat?

I'm asking because of this one, I had to flag a large number of messages that were just veered of the topic of the challenge and are completely irrelevant to the challenge, but it is hard to keep up with flagging, so maybe it would be better for this discussions to take place in a chat.

Q: Parallel resistance in electric circuits

Introduction: Two resistors, R1 and R2, in parallel (denoted R1 || R2) have a combined resistance Rp given as: $$R_P = \frac{R_1\cdot R_2}{R_1+R_2}$$ Three resistors, R1, R2 and R3 in parallel (R1 || R2 || R3) have a combined resistance (R1 || R2) || R3 = Rp || R3 : $$R_{P_2} = \frac{\frac{R...

@flawr I just deleted all of them. Who cares if it's an argument by contradiction or not?

I'll move to chat if there's a valuable discussion that's going on too long

But that had nothing to do with the challenge

flawr

@DJMcMayhem Ok thanks. The discussion was not uninteresting per se, because I - as many others, apparently - wasn't aware of the different perspectives but it was just in the wrong place.

@DJMcMayhem but so mods can move things to chat?

Thomas Ward

@flawr i think the 'short answer' to your question is mods do have the ability to move all comments on a post to a chat room

but that's all comments not selective ones

so you have to have a 'long standing' conversation of some nature of being valued, OT discussions and such don't count ;)

(neither does bickering, on any site)

also greetings,

(been a while since I said hi here :P)

DJMcMayhem

o/

Thomas Ward

hope you don't mind me answering on behalf of 'mods' in general @DJMcMayhem ;)

how's it going here?

DJMcMayhem

Same as usual

flawr

14:49

@ThomasWard ah ok, thanks for explaining

We should introduce a light pollution function to fight the occasional star spams.

Erik the Outgolfer

@ThomasWard I've actually seen a comment on top of an automatic mod to chat comment

DJMcMayhem

What do you mean?

Erik the Outgolfer

can't link any particular example rn, but

Thomas Ward

@EriktheOutgolfer usually means someone commented before or after the mod got to it, or the comment didn't transfer, seen both cases :p

but regardless, mods do have the capacity to 'move' comments but that doesn't prevent new comments from being posted

Erik the Outgolfer

here is a sample order of two comments, top-to-bottom:

comment 1 — non-mod, timestamp1
[comments moved to chat] — mod, timestamp2

where timestamp1 < timestamp2

DJMcMayhem

14:54

Oh yeah, that probably just means they thought comment 1 was valuable and undeleted it

Fix my stuttered words Stuttering is a problem which many of us might have experienced or at least seen it. Although most of famous speech recognition softwares have serious issues with stuttered speaking, let's imagine a software which understands stuttering, but cannot fix them and only writes...

Erik the Outgolfer

@DJMcMayhem can they really do that?

Thomas Ward

@DJMcMayhem this. There have been cases where I've done that too

@EriktheOutgolfer 'they' meaning mods

mods can undelete ;)

Erik the Outgolfer

I know... :P

DJMcMayhem

@EriktheOutgolfer Yeah, comments aren't moved so much as copied and deleted

Thankfully in one step

Erik the Outgolfer

14:56

which can't be redone from what I've read...

DJMcMayhem

I think so? I don't remember running into that

Thomas Ward

once the chatroom is made the system barfs if you try and create a second chat room, yes.

Erik the Outgolfer

some mods have edited the automatic comment to include something like "we can only move comments once; further discussions will be just deleted"

Thomas Ward

but that's a different discussion

DJMcMayhem

@EriktheOutgolfer Thankfully PPCG doesn't get really controversial topics very often so we never need to post that :P

flawr

btw: how does mathjax work in our comments?

Erik the Outgolfer

just like in posts; \$ and $$ both work

@DJMcMayhem ... either that or people are scared off by the diamonds xD

flawr

@EriktheOutgolfer I just tried but it doesn't seem to work here (or do you see latex in my comment?)

@DJMcMayhem how dare you to make such a claim? you're very wrong

Erik the Outgolfer

hm, no latex over there...

@ThomasWard pretty sure our diamonds don't look very scary... ;P

Thomas Ward

15:08

@EriktheOutgolfer heh

flawr

why do people call this "diamond" anyway? it doesn't look like diamonds at all

Erik the Outgolfer

Thomas Ward

@EriktheOutgolfer heh true. but... flag a chat post with a mod flag, and watch the Diamond Storm. :P

flawr

@EriktheOutgolfer no latex for you either?

Erik the Outgolfer

yeah, no latex

although it does show latex if I post a comment on one of my answers

Veskah

@AdmBorkBork You don't know of any measure-command voodoo that's shorter than just doing $int_array|%{$accumulator+=$_} for a simple add-up, do you?

AdmBorkBork

@Veskah The only alias for Measure-Object is measure which is already ridiculously long, so I'm not aware of anything short.

H.PWiz

17:53

@SriotchilismO'Zaic Irregardless of total length?

Sriotchilism O'Zaic

Probably as a tie breaker

DJMcMayhem

Not without regard.

H.PWiz

(Apparently it's non-standard)

El'endia Starman

Irregardless is a great example of a word that's "incorrect" but is getting used so much that it's becoming a valid word anyway (uses of irregardless should be regardless to be "correct").

Sriotchilism O'Zaic

How is it incorrect?

Wiktionary is saying that it is just a portmanteu of irrespective and regardless.

Poke

18:00

it's nonstandard

but if enough people use "fake words", then they're no longer fake

Sriotchilism O'Zaic

So its just like other neologisms?

DJMcMayhem

@SriotchilismO'Zaic Because it literally means "not without regard" which is the opposite of how it's used

Kinda like "I could care less" or "Literally"

Sriotchilism O'Zaic

I don't see how these three things are related.

Oh I see I think

the ir- prefix is suppoesed to mean not, I did not know that.

H.PWiz

@primo That's awesome. I haven't seen how to 66 with it yet :)

Sriotchilism O'Zaic

I see how that is like "I could care less" but how is it like "literally"?

El'endia Starman

18:03

A major meaning of "literally" is "figuratively".

DJMcMayhem

Because "literally" is used to mean "figuratively", like literally all the time

El'endia Starman

I typically take a descriptivist view of language, but I hate how my generation made literally mean the opposite.

DJMcMayhem

@El'endiaStarman I would agree with descriptivist, but literally doesn't bother me too much. "I could care less" drives me crazy

Sriotchilism O'Zaic

Are you sure that people are not just using literally hyperbolically?

I would never say "figuratively all the time".

DJMcMayhem

It is hyperbole I'm sure, it's just that hyperbole is the exact opposite of literal

(Or the literal opposite?)

Sriotchilism O'Zaic

18:07

Not really, the hyperbole is false but the figurative nature of the claim is assumed to be known not provided with "lterally".

El'endia Starman

@SriotchilismO'Zaic Likewise for prefixes like im-, in-, un-, etc. E.g. possible and impossible. Caution: flammable and inflammable still mean the same thing because they have different etymological roots.

Sriotchilism O'Zaic

The problem with descriptivism is that you can't ever say that descriptivism is better than prescritivism otherwise you would become a prescriptivist.

DJMcMayhem

English is hard, but it can be understood through tough thorough thought though.

@SriotchilismO'Zaic Claiming descriptivism is better than prescriptivism is making a claim about linguistics, not a claim about a language

Sriotchilism O'Zaic

Ah but prescritivism and descriptivism are both expressed through the way you describe language, which is a speech act.

(I am joking though)

flawr

@El'endiaStarman I guess I confess I couldn't care less about irregardless' infectuous incorrectness, but I digress.

caird coinheringaahing

18:22

@DJMcMayhem I could be wrong, but did you mean to say is a hard? Given the discussion, it could be some archaic grammatical rule, but ¯\_(ツ)_/¯

DJMcMayhem

Definitely did not mean that

caird coinheringaahing

Mod abuse :P

Accept your mistakes :P

Erik the Outgolfer

at least he didn't do the other abuse... :P

Inflammable means flammable?
