Okay, cool.

@EasterlyIrk yeah, I'm working in develop atm

Easterly Irk

Well, it works for me now (with the extra parend) \o/

@Quill how do you enter a command in the SE chat terminal?

@TogaDown Carefully

@VoteToClose That's...oddly mesmerizing...

@Quill how do you send messages????

The command thing is broken, it only does one

Dennis

@VoteToClose :) You should have waited for my C port though. After a gazillion segmentation faults, I finally got it.

Quill

it's a lot harder than

Dennis

C can be infuriating, but damn it's fast.

@Dennis 149,787.5 times faster than my submission.

Toga Down

who needs speed when you can have JavaScript :P

Easterly Irk

Because C goes directly to machine code?

El'endia Starman

@NathanMerrill Near all languages are on top of C.

Nathan Merrill

3:15 AM

@EasterlyIrk you can do that with any language, technically

Alex A.

if (prime_index >= top)
    printf("whoa\n");

@Dennis ^ lel

Toga Down

@NathanMerrill not all langauges

Easterly Irk

@TogaDown pls send me your working terminal chatter

Nathan Merrill

right, but why doesn't somebody make a different language (that avoids the problems C has) that compiles directly to assembly?

VoteToClose

Which, by the way, is still running.

Dennis

3:16 AM

@AlexA. Hahaha, I forgot to take that out. Is printf("sofa so good\n") still there?

mınxomaτ

@TogaDown JS can be pretty fast with the right engine.

Toga Down

@NathanMerrill you mean JavaScript (SpiderMonkey)?

Easterly Irk

@VoteToClose oh god lol

El'endia Starman

@NathanMerrill Well, I think Fortran is still an option...

Toga Down

@mınxomaτ asm.js is also pretty damn fast

mınxomaτ

@TogaDown That has nothing to do with anyhting.

Alex A.

@El'endiaStarman I don't mind Fortran so much. Well, 90+ anyway.

Nathan Merrill

Fortran isn't high enough

Alex A.

It needs to smoke a dooby first?

Toga Down

3:17 AM

@mınxomaτ asm.js is like C compiled to fast JavaScript iirc

Nathan Merrill

@TogaDown spidermonkey is built on C++

El'endia Starman

@NathanMerrill And there's your problem.

Toga Down

wait no that's Emscripten

El'endia Starman

You trade off between speed and usability.

Dennis

@AlexA. I'd take it out, but if I do, it segfaults again. ._.

mınxomaτ

3:17 AM

@TogaDown asm.js is a syntax description of a ECMAScript subset. I'm talking about engines.

VoteToClose

@EasterlyIrk YUS IT JUST FINISHED.

Toga Down

@mınxomaτ yes, I meant Emscripten produces fast JavaScript

Alex A.

@Dennis That's both incredibly hilarious and oddly troubling.

@Dennis

Nathan Merrill

3:18 AM

@El'endiaStarman that's not strictly true, but somebody could make a language that uses the advances in language design to create a new language that compiles to assembly

Easterly Irk

@VoteToClose woah

\o/ though

mınxomaτ

@TogaDown It produces asm.js compliant JS, not "fast JS". Some browsers may optimize for asm.js. That depends on the engine.

Easterly Irk

@Upgoat why?

Upgoat

because upgoat != -toga down

feersum

@NathanMerrill Of course, there are many languages like that

Dennis

3:19 AM

@AlexA. And not the first time something like that happens to me...

Nathan Merrill

@feersum enlighten me?

feersum

Like C++, Haskell or Ocaml.

Toga Down

graph says emscripten generated js is faster than normally coded JS

Nathan Merrill

Haskell compiles to assembly?

feersum

To machine code, yes.

Nathan Merrill

3:21 AM

is there a difference?

mınxomaτ

What now, machine code or assembly. And if assembly, what assembly.

Nathan Merrill

apparently there is

feersum

Assembly language is when it's written with words liek MOV, POP etc.

Nathan Merrill

right, but its a 1 to 1 to machine code

mınxomaτ

@NathanMerrill No it isn't.

Easterly Irk

3:22 AM

I is confused.

Toga Down

^

Alex A.

What are you confused about?

Toga Down

22 hours ago, by Downgoat

Je ne comprends pas

mınxomaτ

Assemblers are compilers. They usually optimize. Eg. FASM will always optimize for instruction size, while eg. NASM is almost verbatim.

El'endia Starman

Many/most assembly commands are equivalent to multiple machine code instructions.

mınxomaτ

3:23 AM

But most of them don't really use anything more serious than peephole optimization.

Nathan Merrill

so, if I have an executable, is it machine code or assembly?

mınxomaτ

@NathanMerrill Machine code.

@NathanMerrill Except when it is IL, then the actual binary is called Assembly.

Easterly Irk

@AlexA. EVERYTHING

Nathan Merrill

and if I'm seen code that has jmp commands, then its assembly?

mınxomaτ

Yes.

El'endia Starman

3:25 AM

Yes, unless it's an esolang. :P

Nathan Merrill

lol

mınxomaτ

@NathanMerrill Technically, the only instruction you ever need is mov: github.com/xoreaxeaxeax/movfuscator

MOV in itself is Turing Complete.

Alex A.

Esossembly

Nathan Merrill

so, does Haskell, Ocaml produce assembly code, and use the same assembler as C/C++ code?

(typically)?

mınxomaτ

@AlexA. That is the only feasible and almost irreversible binary obfuscation.

Dennis

3:27 AM

@AlexA. OK, I added a print statement elsewhere, and now I can use -O2. How am I supposed to debug my code like this...?

mınxomaτ

@NathanMerrill Depends on the compiler. Haskell doesn't produce anything, since Haskell is just the language. The compiler might carry a different name.

Alex A.

@Dennis Code Review? ¯\_(ツ)_/¯

Dennis

Alex A.

Stack Overflow?

Nathan Merrill

3:29 AM

@mınxomaτ I know that languages != compiler, but I'm just curious about the process

Dennis

I think they're tired of off-by-one errors.

Nathan Merrill

do different compilers generally use the same assembler?

mınxomaτ

@NathanMerrill Also, there are edge-cases like my programming language Perseus, which is technically a high level language and an Assembler, because it compiles directly to machine code without ever generating Assembly code.

Quill

@Dennis I think they usually try to close those under typographical errors

Toga Down

Does anyone know if Mac uses .bashrc or .bash_profile

Quill

3:30 AM

profile

VoteToClose

^

Toga Down

but bash profile doesn't work

Quill

in what context

mınxomaτ

@NathanMerrill The depends on the platform mostly. Eg. C in gcc will use the GNU assembler, MSVC will use MASM etc.

Toga Down

uhh

like it does nothing

Upgoat

3:31 AM

isn't rc for commands, and profile for PATH/environment variables?

@TogaDown export VARNAME = value?

@Dennis I think you can speed up your Python code even more if you make sieve a list of booleans and set sieve[i::i] = false rather than constructing [0] * len(sieve[i::i]).

I could be wrong though.
