Grandi's series

In mathematics, the infinite series 1 − 1 + 1 − 1 + ⋯, also written ∑ n = 0 ∞ ( − 1 ) n {\displaystyle \sum _{n=0}^{\infty }(-1)^{n}} is sometimes called Grandi's series, after Italian mathematician, philosopher, and priest Guido Grandi, who gave a memorable treatment of the series in 1703. It is a divergent series, meaning that it lacks a sum in the usual sense...

> It should be noted that the term summation can be misleading, as some statements and proofs regarding Cesàro summation can be said to implicate the Eilenberg–Mazur swindle.

El'endia Starman

Well, at least I can contribute further! We're looking for n(n+1) = m(m+1)/2.

Okay, what if one star was 1 rep, not 10 rep?

Can somebody link me the sandbox again?

Nevermind, found it.

Rohan Jhunjhunwala

@ColdGolf because its not contributing to the sight in any way. Stack Exchange aims to be a quality tepository of question seekers and answerers. It aims to be a collection of knowledge from experts in their field (for ppcg the field is code golf). Saaying humoruous things in comments should not be awarded?

ColdGolf

@RohanJhunjhunwala I mean, technically, ppcg is more of fun than asking questions.

Don't tell that to the admins, though. Heh.

Leaky Nun

Something clever and interesting worthy of being starred

El'endia Starman

@RohanJhunjhunwala s/sight/site

Conor O'Brien

@LeakyNun nice try.

ColdGolf

1:25 AM

Posting latex in the sandbox displays normally with ChatJax.

Posting the exact same latex in here, doesn't work.

Weird.

Leaky Nun

@ConorO'Brien Outgolf our Python solutions

or submit a solution in J

Conor O'Brien

fixed output?

ColdGolf

Something useless and boring that isn't worthy of being starred.

Leaky Nun

@ConorO'Brien yes, my style

Rohan Jhunjhunwala

@El'endiaStarman sorry my bad.

Conor O'Brien

1:26 AM

doing a J submission even though I should be doing notes

do I need an account

Leaky Nun

@ConorO'Brien no, that's the point of the website

Conor O'Brien

oh, fun

Rohan Jhunjhunwala

@ConorO'Brien golfing code is a life skill. Everyone knows that programmers should be paid based on the number of semicolons they use. (Relevant Post)

47

A: Is fewer lines of code always better?

Code with as few lines as possible is definitely the best code and every semi-colon you see is basically the developer admitting they weren't clever enough to use advanced constructions like the comma operator or short-circuiting operators to keep the line going as long as possible like you can s...

@LeakyNun I'd VTC this website as completely unclear what the challenge even is.

Leaky Nun

fucking hell

Rohan Jhunjhunwala

1:28 AM

Um...

Problem? @LeakyNun

Leaky Nun

@RohanJhunjhunwala Not saying to you

Rohan Jhunjhunwala

@LeakyNun ok, its a bit disconcerting to see something like that out of the blue

Conor O'Brien

@RohanJhunjhunwala lol

@RohanJhunjhunwala I think it's a beer as well

Rohan Jhunjhunwala

@ConorO'Brien oh I've seen that joke in tnb too often lol

El'endia Starman

@ConorO'Brien Yes, a beer brewed in a particular German town, IIRC.

Conor O'Brien

1:30 AM

ah, so I'm late

ColdGolf

@El'endiaStarman I see you go to the school of Twisting Peoples' Words To Mean Something Else.

Rohan Jhunjhunwala

@ConorO'Brien @Others who liked my programmers.se post, you may be interested in this repo

github.com/elitheeli/stupid-machines

ColdGolf

@RohanJhunjhunwala GitHub looks awful without the wider github script...

Rohan Jhunjhunwala

Semicolons are completely optional in java

El'endia Starman

@ColdGolf Did you start your bot again? You're starting to slip into inanity again...

ColdGolf

1:34 AM

I was just copypasting an earlier message of yours.

Isn't that a bit ironic?

Conor O'Brien

@El'endiaStarman I thought it was always on.

:P

El'endia Starman

@ConorO'Brien Well, after this message, most of their messages were actually relevant.

Conor O'Brien

I couldn't tell

thanks

ColdGolf

@El'endiaStarman I mean, I told everybody I was gonna use a bot for a couple of minutes. Nobody could complain, but only if they had already knew this.

El'endia Starman

@ColdGolf Can you link me to the message where you said this?

@zyabin101 I'll switch it on, it's sloooow API tho

Rohan Jhunjhunwala

You know there is a unique feature, left click a profile and you get a few options which may interest you in using :)

El'endia Starman

@RohanJhunjhunwala I think it would be detrimental to my modly duties to ignore problematic users. :P

ColdGolf

@El'endiaStarman Or to be problematic yourself.

Rohan Jhunjhunwala

@El'endiaStarman oh whoops, but perhaps it may interest Conor O Brien

El'endia Starman

@ColdGolf Certainly. I think, however, that community consensus is that the problematic one is not me. :P

ColdGolf

1:42 AM

@El'endiaStarman Does your definition of community include only the mods? :D

Geobits

@RohanJhunjhunwala How do you define "java"? They don't do anything to the byte code, but I've yet to find a standard java compiler that will allow you to leave them out completely (although there are some cases where they're optional).

El'endia Starman

@ColdGolf I was not aware that Conor, Leaky Nun, and Easterly Irk were mods.

Rohan Jhunjhunwala

His definition of community is the starred responses on the starboard @ColdGolf

El'endia Starman

Oh, and xnor too.

Rohan Jhunjhunwala

@Geobits I am unsure what you are talking about

ColdGolf

1:43 AM

@El'endiaStarman When did I say that they were?

Also, are 5 users the entire community?

I don't want to start a long argument.

Rohan Jhunjhunwala

@Geobits did I send you a message I forgot about :( my bad

Geobits

Semicolons are completely optional in java

DJMcMayhem

@El'endiaStarman wait, are you able to see who has ignored a user?

Conor O'Brien

@RohanJhunjhunwala what may interest me?

@El'endiaStarman of course I'm a mod!!! !drop table TNB_USERS

Geobits

@DJMcMayhem It's not hard to list off a few people in this instance, even without knowing that.

El'endia Starman

1:44 AM

@ColdGolf I think it's pretty telling that there are at least five people in agreement versus one in disagreement. And I'm only counting those that I can remember have explicitly said something; this message of mine has 10 stars.

Rohan Jhunjhunwala

@Geobits I was talking about the above repo I linked. @ConorO'Brien left click a user ahem ahem, and some interesting options pop up
Also this repo is what I was talking about
https://github.com/elitheeli/stupid-machines

ColdGolf

Imaginary internet stars at that.

Did you forget about https://chat.stackexchange.com/transcript/message/31891785#31891785 ?

The part I told you to read previously, when you asked me to link it.

Conor O'Brien

@RohanJhunjhunwala yes, I saw the repo

Nathan Merrill

you know, I'm quite glad I'm not a mod. I don't think I could ignore people if I was

Rohan Jhunjhunwala

@ConorO'Brien the options that interested you I was talking about was the ignore feature ...

Conor O'Brien

1:46 AM

@RohanJhunjhunwala I already have ;)

El'endia Starman

@ColdGolf Please don't repeatedly edit messages with pings.

Rohan Jhunjhunwala

;)

ColdGolf

@El'endiaStarman Oh, it pings you again? I see.

Conor O'Brien

@NathanMerrill I concur. Mostly because it's hard to align carrots with ignored messages inbetwixt

Nathan Merrill

Actually, ignores are a really good reason to stop using carets

Geobits

1:47 AM

@NathanMerrill Every now and then I wouldn't mind having room-owner powers though. Just occasionally >_>

Syxer

Update: My web-knife is still running

ColdGolf

Sorry, But I have to nitpick your drop table usage.

The format is `DROP INDEX name_of_table.name_of_index`

Q: Should we have additional room owners?

Currently our main chatroom, The Nineteenth Byte, has only the 4 PPCG moderators as room owners. Since the chatiquette is not applicable to other Stack Exchange sites, using chat flags for breaches of chatiquette which are not also network-wide offenses is problematic - wasting the time of 10k us...

Maybe you could

Nathan Merrill

@Geobits yeah, we just need sudo for the chat room

Geobits

@DJMcMayhem Haha, well I wouldn't volunteer myself for the job, but I'd probably take it if offered.

ColdGolf

1:48 AM

The community is divided on this.

I personally both agree and disagree at the same time about it.

Q: Evaluate expressions with significant figures

Given an expression, your task is to evaluate it. However, your answer cannot show more digits than necessary, as this gives the impression of having more precise measurements than reality. The number of significant figures that a number has is how many digits it has when written in scientific n...

code-golf math

DJMcMayhem

@Geobits I'm more just curious if you agree with my answer on it, haha

Geobits

Oh, I upvoted it just now. I hadn't seen that you answered before that.

Nathan Merrill

yeah, I upvoted it as well. I actually agree with Alex A as well (in that it isn't necessary, as our chat is pretty well moderated), but that I don't really see any harm in having extra owners, but I definitely see potential benefit

Mitch Schwartz

wait is ColfGolf disliked mainly because of behavior in chat or the site or both?

DJMcMayhem

1:53 AM

@NathanMerrill yeah, I suppose users like quill, trichoplax abs elendia (non ppcg mods) does help a lot.

El'endia Starman

@MitchSchwartz Mostly chat, so far as I know.

ColdGolf

@MitchSchwartz I'm disliked by people who either hate specific memes, or just don't know them.

Question: Is there an online tool that can show if a given chess position has a checkmate/stalemate?

Mitch Schwartz

i thought people around these parts liked memes

DJMcMayhem

Although I'm still shocked by some of those statistics I posted. I honestly think this might be the most active chat room

ColdGolf

1:54 AM

@MitchSchwartz I've stopped using them. Evidently, nobody likes them.

Except maybe a few.

Syxer

Guys I just figured out something amazing

ColdGolf

@Syxer ??

Syxer

You can embed Skype calls in webpages

Geobits

@MitchSchwartz Not really obnoxious, all screaming caps ones for sure.

ColdGolf

@Syxer You mean call recordings?

Or the Skype web app?

Syxer

1:55 AM

If an end user has Skype open and you use the following HTML, you can make them call a target whenever they click the link:

<a href="skype:8:<username>">link</a>

El'endia Starman

@Geobits You were actually the first that came to mind when the idea of appointing room owners was brought up.

Rohan Jhunjhunwala

Just be sure to not parse the html with regex @Syxer

Syxer

@RohanJhunjhunwala Of course

DJMcMayhem

@El'endiaStarman was it brought up recently? (Other than meta)

ColdGolf

@Syxer What???

Syxer

1:57 AM

@ColdGolf yeeeesss

Tested on Mac OSX El Capitan, newest Skype update.

ColdGolf

That could potentially be a huge security issue. Tell that to the Skype team and pssibly get a bug bounty!

Geobits

@El'endiaStarman It came up a couple times during mod talks, too, IIRC. And there was a room owner strawpoll once, but in jest (I think). People seem to think I'm mature for some reason. Or at least some people.

mınxomaτ

That isn't a security issue by any stretch of the imagination.

Syxer

@ColdGolf Not really - IP harvesting is already done by the user when they connect to the page, as long as there's no further exploitation through Skype, it's fine.

El'endia Starman

@DJMcMayhem Starting around here.

Downgoat

1:58 AM

question: do we have a challenge to output the permiter given coordinates?

ColdGolf

I thought Skype resolved its leaking IP issues a while ago?

Or was that only for non-contacts?

Nathan Merrill

@Geobits that strawpoll is surprisingly even

Rohan Jhunjhunwala

@Downgoat no, I love it. Sandbox it!
