I've outsourced my pi(x) calculations.

You should be able to see the output if you click my name on the sidebar and look at my currently open window.

Probably annoying the cloud9 people. >.>

Oh well.

LegionMammal978

@VoteToClose Also, you should re-compile the jars.

I would, but I'm unsure as to the parameters you used.

@LegionMammal978 Probably a good plan. :P

It's the standard Eclipse jar export.

LegionMammal978

Also, are you running OSX?

I am.

Cᴏɴᴏʀ O'Bʀɪᴇɴ

8:13 PM

(」゜ロ゜)」

The ._MACOSX thing?

LegionMammal978

I noticed that the jars are full of .DS-stores

I'm not sure how to get rid of that, or the .DS_STORE

Yeah. :P

Deleting 550,000 tweets. That's a first. Let's see how long this will take...

Those are annoying, and seemingly impossible to remove.

Cᴏɴᴏʀ O'Bʀɪᴇɴ

8:13 PM

@VoteToClose This looks like part of an emoticon... ._.

LegionMammal978

It's .DS_Store

._. disappoint

@LegionMammal978 I was close?

El'endia Starman

@mınxomaτ ...why?

LegionMammal978

Me too :p

@El'endiaStarman I'm roomba-ing my twitter bot. You can see the tweet count slowly decreasing.

Very slowly.

El'endia Starman

8:16 PM

@mınxomaτ I knew it was your twitter bot. My question is why you've decided to delete its tweets. Planning on retiring it, or making a blank slate to start over?

@El'endiaStarman Haven't decided yet. The services that push the tweets are not on my actual server, so it'll be extremely hard to stop them (they're posting 350+ tweet/day).

El'endia Starman

wow

Now twitter banned the roomba. It stopped deleting -.- ...

Cᴏɴᴏʀ O'Bʀɪᴇɴ

XD

El'endia Starman

So....Twitter banned the deleter, not the poster? o.O

8:23 PM

Hm. Now twitter tells me that I have no tweets, but my tweet counter still says 540,000

shouldiblamecaching.com

Cᴏɴᴏʀ O'Bʀɪᴇɴ

>_>

Looks like the counter doesn't reset :D

I broke something.

Cᴏɴᴏʀ O'Bʀɪᴇɴ

Congratulations, you broke twitter.

Does anyone know a good, monospaced, square font?

What do you mean "square"?

Cᴏɴᴏʀ O'Bʀɪᴇɴ

8:33 PM

As in, characters measure the same height and width.

Bitmap or O/TTF?

@LegionMammal978 Seems that I need to change some things about your pull request; setind needs to be changed to match the new index.

Cᴏɴᴏʀ O'Bʀɪᴇɴ

For a website.

Any math people here?

Cᴏɴᴏʀ O'Bʀɪᴇɴ

YES

I LOVE MATH

8:37 PM

Math is okay.

El'endia Starman

I'm like Conor in this case. :P

Cᴏɴᴏʀ O'Bʀɪᴇɴ

\o/

My username notwithstanding.

Well I have a question: I am looking for a (simple) example of a non noetherian ring.

But I do not want to google it, as I try to discover it my self.

Cᴏɴᴏʀ O'Bʀɪᴇɴ

nope

8:40 PM

Then again I have no idea where to start.

Cᴏɴᴏʀ O'Bʀɪᴇɴ

I don't know much topology yet

It is rather a part of algebra, but still the properties "noetherian" and "compactness" have some similarities if you squint your eyes.

So if anyone could give me a slight hint on where to start searching I would be grateful=)

What is noetherian?

Do you know what a Ring is?

yes

8:43 PM

An Ideal?

maybe...

Well an Ideal is a additive subgroup of a Ring, with some kind of "absorbing" property.

That is if you take any element of the ring and any element of the ideal, the product of the two is again in the ideal.

yes

And noetherian means that increasing chain of ideals (increasing as in one is a subset of the next) becomes stationary.

That is that after some point the rest of the chain all MUST be the same ideal

So you're looking for one with an infinite chain?

8:46 PM

Exactly!

El'endia Starman

...wow, not only did Abel get the honor of a lowercased adjective, so did Noether. Cool.

Euler did get a lower case constant=)

* at least one.

El'endia Starman

haha

What do I have to do to get an adjective?

Martin Büttner

maths

lots of it

and good maths too

8:48 PM

Would 2Z, 4Z, 8Z, ... on the integers work?

That's going in the wrong direction.

Nope, the Integers are noetherian.

As the chain would be 8Z < 4Z < 2Z

(the elements of 4Z are contained in 2Z but not vice versa)

8Z <= 4Z <= 2Z <= Z <= Z ...

<= 0

But then it is getting difficult=)

Well, depending if you require an 1 in the definition of rings=)

Well, a non-Noetherian ring has to have a countably-infinite number of elements in it, right?

8:53 PM

Sure, non-noetherian rings are quite big.

Finite and finitely generated rings are all noetherian.

How about element-wise addition and multiplication on infinite sequences of integers

A: Sandbox for Proposed Challenges

What is the "Ant-Difficulty" of this string? A code-golf challenge. I think about if I was turned into an ant, I'd want my loved ones to know, so I thought of a plan- I'd gather twigs and leaves and write my name on the ground, Then I'd wait for my family and friends to crowd round B...

The first ideal is 2Z X 2Z X 2Z ...., the second Z X 2Z X 2Z ..., etc.

That could work

Thinking of it, that is just a ring with a infinite series of variables adjoined.

E.g.

Why not just the real numbers, then?

8:58 PM

Z[X1,X2,X3,X4,X5,....]

@PhiNotPi The real numbers are not only a ring, but also a field.

And fields do only have two ideals: 0 and the field itself.

@feersum I think it might be difficult to classify all ideals on that ring.

Are there any other than aZ X bZ X cZ X dZ ... ?

I don't know, that is why I'm not sure=)

Well nZ is the only one on integers right? So I'd think each element has to be one of those

In math, as soon as something becomes infinite, trouble arises.

@feersum This does not quite work, but it can be saved!!!

I hereby decree that sequences with an infinite number of elements that are not equal to 2 are not allowed in my ring.

Oops, I just banned 0.

9:07 PM

Consider the chain of ideals [2Z,2Z,2Z,...], [Z,2Z,2Z,2Z,...], [Z,Z,2Z,...] , ....

It is infinite, without becoming stationary.

That's what I said, right?

Oh, I did not understand it then=)

In that case: Thank you=)

@feersum The feersumian rings.

Let's write a wikipedia article to make it official.

This is really odd.

Java is not being consistent with outputs.

ಠ_ಠ @RikerGoat This name is unacceptable.

It is java though. Never trust it.

@VoteToClose ಠ_ಠ

I like my name.

It seems to be exiting before getting somewhere, but I have no idea why, but when I debug it, it's fine.

9:21 PM

What is wrong with my name?

It's goaty.

There are so many goats. D:

(also, facetiousness. :P)

Martin Büttner

@VoteToClose congratulations. you've got a Heisenbug.

I might swap back and forth.

Oh, I'm an idiot. xD

"$" is a special character and I didn't escape it.

/me facepalms.

It's working now. :D

I am only Riker goat here, not on my main account.

Better @VoteToClose?

9:26 PM

I honestly don't have anything against the name. xD

I was joking.

I don't have anything against "goaty" names

Just a lot of goats... Downgoat, Upgoat, DJMcGoathem, RikerGoat...

Maybe I should be GoatToClose?

GoatTooClose. O.O

I vote yes.

That one's so good that I might have to use it. D: So much for CoolestVeto

^

9:29 PM

Ooh, that's another good one.

I can't think of any good anagrams for my name.

Maybe, My Ham DJ?

Lol yes

Brb goatifying

My Ham DJ. xD

That's not a proper anagram, though, because it doesn't use all the characters.

Pls halp i tri eat can and be goat for thirtee minut but much tongue hurt

Oh, dang it you're right.

Oh, yay, there's a new wonderful way to StackOverflow in my language. \o/

@DJMcGoathem Vitsy.

@RikerGoat ihaichualiddlbit

Man, I need to learn a golfing language.

9:34 PM

Vitsy is sorta a golfing language.

It's moving both towards and away from that right now.

Martin Büttner

@DJMcGoathem yay for CJam

I want to make a vim-based golf-language, but I don't know how to.

@DJMcGoathem Yay for Vitsy, because my child needs more supporters!

I should make StackOverflowExceptions a builtin. o-o

Really? I think it sounds awesome. Vim's already decent at golfing if it's a string-manipulation challenge. It just needs better support for conditionals, loops, user input, etc.

Oh, wait, it kinda is...

@DJMcGoathem :D Join the "I made a programming language!" club! :D

:D :D :D

9:37 PM

Haha, I keep trying but I don't know where to start.

Right now i'm looking at github.com/neovim/python-client

... I didn't know that this was a thing.

catch (Throwable e)

^ That shows up in Vitsy now.

It's now catching errors like a champ. \o/

@DJMcGoathem My suggestion: build from absolute scratch. You can have inspiration, sure, but don't build off other stuff.

@VoteToCloseYeah, I might end up doing that. It's a terrifying idea though, considering vim is 500,000 LOC.

You should probably just make it a vim plugin that adds the commands

^ That makes it a golfing library, not a language.

@VoteToClose beats the shit out of rewriting vim or trying to make a weird transpiler though

9:54 PM

Sure, but I wouldn't say it's a programming language.

@RikerGoat At least it isn't called "How to avoid the twin towers". ;)

Oh jeez

Jessie must be a medium. Your llama can't find someone to talk to the spirit realm.

@MartinBüttner Get somebody else to do it.

Every single command that I do with it says no medium found on /dev/sdb

Hmm.

yes

Does it work on other devices?

I don't know, haven't tried (it's a completely new SD card)

If you have an Android, test it with that. It'll do formatting and stuff if it can.

I do, but that's a lot of effort :P

Effort is the worst.

Hmm. Did you already check the sshd logs?

Nothing unusual.

According to the server yes, but PuTTY is just derping.
