@AlexA. You know about asm.js, right? It is plenty fast.

cat

@mınxomaτ LOL

CSᵠ

@AlexA. yeah, but @scratch :)

Alex A.

00:11

@mınxomaτ No, I'm not familiar with asm.js. Is it anything like Node.js?

mınxomaτ

@AlexA. No.

ev3commander

@AlexA. Well at least flash.speed() < js.speed()

@AlexA. It is a subset of JavaScript that is extremely optimized for speed in almost all modern browsers.

Asm.js

asm.js is an intermediate programming language designed to allow computer software written in languages such as C to be run as web applications while maintaining performance characteristics considerably better than standard JavaScript, the typical language used for such applications. asm.js consists of a strict subset of JavaScript, into which code written in statically-typed languages with manual memory management (such as C) is translated by a source-to-source compiler such as Emscripten (based on LLVM). Performance is improved by limiting language features to those amenable to ahead-of-time...

@mınxomaτ wait, does that mean i can make C run in a browser? I thought it was just asm

Alex A.

@quartata Yes, quartapotatoes, I am listening.

RikerW

00:13

@AlexA. i noticed something a while ago. The only people who ever post in julia are you and Glen O. Since I am learning julia, do I have to change my name to Riker W. ?

mınxomaτ

@cat Yes, use emscripten to compile C to asm.js. It even supports OpenGL (Unity is written in asm.js).

quartata

@AlexA. I didn't mean actually listen to me..

Alex A.

@RikerW Uh... no?

quartata

I was just simulating your chat experience.

Alex A.

I know

RikerW

00:14

@AlexA. Think about it. Alex A., Glen O., RikerW.

mınxomaτ

@cat You could even use LLVM to compile C++ to asm.js, though that is highly complex.

quartata

@RikerW But I used Julia once.

RikerW

@quartata Did you post it as an answer?

quartata

Yes.

Alex A.

@RikerW quartata, ಠ_ಠ, Martin Büttner, and alephalpha have also posted in Julia, Glen and I are just the ones that do it almost exclusively.

quartata

So if you plan to post only Julia answers, yes, change your name.

Otherwise you're free to be an individual.

El'endia Starman

Google Translate has "Can not count" as the translation from Chinese and "Uncountable" as the translation from Japanese.

LegionMammal978

There, put on a hat :P

ev3commander

00:26

Literally chinese for "Easy" is "Allow easy"

El'endia Starman

And I get this when trying to translate "eight million" to Japanese: "800万".

LegionMammal978

So 800*10000?

quartata

Google Translate sucks with numbers.

I must say.

LegionMammal978

Makes sense

El'endia Starman

"Myriad" means 10,000, in fact.

It is a word we have in English.

SuperJedi224

00:27

@El'endiaStarman Yes I know. That's included on my number list.

RikerW

@SuperJedi224 Are you the expert on large numbers now, because you have a really long list?

quartata

@RikerW Yes.

LegionMammal978

Just try to put Graham's number on it :P

RikerW

@quartata I am wishing I had an onion to put on my head.

SuperJedi224

I'm far from being the expert. I'm sure Sbiis Saibian, Lawrence Hollom, et al. know more.

@LegionMammal978 I'll get there eventually

(I'm asuming you mean the Graham-Gardner Number?)

El'endia Starman

00:30

> ("八百万" literally means eight million, but idiomatically it expresses "uncountably many" and "all around"—like many East Asian cultures, the Japanese often use the number 8, representing the cardinal and ordinal directions, to symbolize ubiquity.)

LegionMammal978

Never heard of that, was talking about this number

quartata

That's the number he means.

SuperJedi224

Basically: Yes.

El'endia Starman

"Gardner" refers to Martin Gardner, who popularized Graham's Number.

@SuperJedi224 Define f(x) as f((x-1)*900)*...*f(1)*Ackermann(x*1000,x*1001) where f(1) = 16384. My number is f(f(f(f(16384)*16384)*16384)*16384).

SuperJedi224

@ev3commander I believe that exibits expandal growth, roughly.

So with the iteration you have there, I think we're looking at order w+2.

Okay, now it isn't even well defined.

ev3commander

And then g(n,x, j) = f(f(f(f(...f(x)*j)*j)...*j)*j) with n f's and j's

Your function is still not well defined.
