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.

VoteToClose

@LegionMammal978 Probably a good plan. :P

It's the standard Eclipse jar export.

@LegionMammal978 I was close?

@mınxomaτ ...why?

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

20:16

@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?

mınxomaτ

@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

mınxomaτ

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

mınxomaτ

20:23

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

Cᴏɴᴏʀ O'Bʀɪᴇɴ

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

flawr

20:40

Then again I have no idea where to start.

Cᴏɴᴏʀ O'Bʀɪᴇɴ

I don't know much topology yet

flawr

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=)

feersum

What is noetherian?

flawr

Do you know what a Ring is?

feersum

yes

flawr

20:43

An Ideal?

feersum

maybe...

flawr

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.

feersum

yes

flawr

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

feersum

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

flawr

20:46

Exactly!

El'endia Starman

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

flawr

Euler did get a lower case constant=)

* at least one.

El'endia Starman

haha

PhiNotPi

What do I have to do to get an adjective?

Martin Büttner

maths

lots of it

and good maths too

feersum

20:48

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

PhiNotPi

That's going in the wrong direction.

flawr

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)

PhiNotPi

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

flawr

<= 0

But then it is getting difficult=)

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

PhiNotPi

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

flawr

20:53

Sure, non-noetherian rings are quite big.

Finite and finitely generated rings are all noetherian.

feersum

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...

feersum

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

flawr

That could work

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

E.g.

PhiNotPi

Why not just the real numbers, then?

flawr

20:58

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.

feersum

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

flawr

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

feersum

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

flawr

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

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

feersum

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.

flawr

21:07

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

It is infinite, without becoming stationary.

feersum

That's what I said, right?

flawr

Oh, I did not understand it then=)

In that case: Thank you=)

I should make StackOverflowExceptions a builtin. o-o

DJ McGoathem

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.

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.

DJ McGoathem

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

Aqua Tart

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

VoteToClose

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

Aqua Tart

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

VoteToClose

21:54

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