@quartata thx

@Dennis thanks and you're welcome lol

tbf I was plannign on bountying on it anyway

just a question of yours or flawr's (on my other challenge) first

Destructible Watermelon

Hey guys what's the consensus on ><> quines with g?

El'endia Starman

@flawr Woah, that's so cool. It's mind-blowing that p=2 gives the minimum value of pi for L^p norms.

@DestructibleWatermelon cheating. It reads source

Go vote so hopefully we can have consensus soon.

mbomb007

Also, I know people have cooperated on solving challenges together before. I'd be open to someone helping me create an extendable prime checker in Minecraft (for the indefinite bounty)

I've got the plans on paper, and a partial .circ file.

Qwerp-Derp

@mbomb007 It's my one right?

mbomb007

Yeah

Qwerp-Derp

4:23 AM

Can I have a look at what you have right now for a "module"?

mbomb007

Idk if it would make enough sense without my paper

Maybe I'll take a pic

quartata

@Qwerp-Derp What exactly are you trying to do with this code

Qwerp-Derp

@quartata Ummm I'm trying to do a for-loop that outputs numbers up to an input n

So with input 5 it should output 012345

But it keeps going forever

quartata

As in outputs forever or doesn't output anything?

Qwerp-Derp

@quartata Outputs forever

The inc works but the cmp and jle doesn't work

mbomb007

4:26 AM

quartata

Oh I see

Qwerp-Derp

@mbomb007 You could use Logicode for that :)

mbomb007

Eh.

It has to be easy to convert to Minecraft

Qwerp-Derp

True

mbomb007

so I'm laying it out in sections

Destructible Watermelon

4:27 AM

how to duplicate a stack in fish...

mbomb007

such that it's extendable by adding a new section, which adds one bit

Destructible Watermelon

or part of a stack anyway

quartata

@Qwerp-Derp You have your mov in the wrong order

Conor O'Brien

@DestructibleWatermelon this is tastefully vague

quartata

You should probably just keep thr counter in another register though.

mbomb007

4:29 AM

@Qwerp-Derp Simply put, the number to check will be commited to the P register. Then, check all numbers from 1 to P-1 and see if they divide P.

Qwerp-Derp

Oh kule

mbomb007

That's what the A and B registers are for

Destructible Watermelon

I want to take the stack, print it out as a string, and then print out a substring at the end again

mbomb007

A is the counter from 1 to P-1, and B will be adding 1 to it.

Destructible Watermelon

hmmmm, the quine part of this will be the hardest part I suspect

Conor O'Brien

4:30 AM

@DestructibleWatermelon you could use a pseudo for loop with the register being a counter

Qwerp-Derp

@quartata So something lie this?

%include "io.inc"

section .data
var DB 0
var2 DB 0

section .text
global CMAIN

print:
    PRINT_DEC 1, var
    inc BYTE [var]
    mov eax, var

forLoop:
    call print
    cmp eax, [var2]
    jle forLoop
    ret

CMAIN:
    GET_DEC 1, var2
    call forLoop
    ret

mbomb007

And if the carry bit is set, then an overflow occurred, and the number is greater than P, so we stop.

Destructible Watermelon

@ConorO'Brien register?

Qwerp-Derp

@mbomb007 Whoa kule, and all of that without command blocks right?

Conor O'Brien

you know, @

quartata

4:30 AM

Nevermind I think I misread your mov

mbomb007

@Qwerp-Derp Yeah

But all the circ file has is the registers, bit adders, and equality comparison.

Destructible Watermelon

@ConorO'Brien doesn't seem like that would work easily at all

mbomb007

I don't have any "if" logic, register init, or edge cases yet. Or any RS-Nor latches to maintain state and stuff.

Destructible Watermelon

also I'm working on one dimension

Conor O'Brien

@DestructibleWatermelon what are you trying to do?

quartata

4:32 AM

You're missing brackets is the problem. mov eax, [var]

Qwerp-Derp

Oh

@mbomb007 Don't you need a less-than check as well?

mbomb007

When it's put into MC, there will need to be latches and repeaters and delays to ensure operations are complete

quartata

Pretty sure

mbomb007

No

Qwerp-Derp

@quartata Nope, still doesn't work

mbomb007

4:33 AM

If the carry bit is set, then R < P.

Destructible Watermelon

@ConorO'Brien I'm trying to take the Turtlèd program embedded in the ><> program, print the Turtlèd program, then print the end of the python program that is in the Turtlèd program

mbomb007

So the > check is if the carry is not set.

Qwerp-Derp

It builds properly without brackets, without any errors

@mbomb007 Ah

Conor O'Brien

oh. well the general quine framework in ><> is something like "r1b3*+!;>?o?|;<your code here>

quartata

I'm very bad at assembly one second

Destructible Watermelon

huh, just realised I could probably simplify the python quine

Qwerp-Derp

@quartata Wot I thought you were expert

Destructible Watermelon

maybe not though

maybe someone else could

argh

quartata

@Qwerp-Derp Wait no you need the [..] in nasm

Destructible Watermelon

why did I pick a 2d language for 1d

quartata

what was the error with brackets

It's probably size

Qwerp-Derp

4:36 AM

@quartata I don't think this is NASM... there's no build errors now

Destructible Watermelon

argh

quartata

What do you mean this is NASM syntax

Destructible Watermelon

this will be irritating

quartata

[...] is dereference in NASM

Qwerp-Derp

@quartata Where did I say it was NASM

I don't need brackets for this, so I doubt this is NASM now

quartata

4:37 AM

In your code because it's written in NASM

Downgoat

So apparently I just spent around ~40 minutes debugging a bug where I misspelt constructor as constractor >_>

Qwerp-Derp

@quartata Is this NASM?

Destructible Watermelon

hmmmm, maybe I should use a similar language

Qwerp-Derp

@quartata There's no difference in output with or without brackets

Destructible Watermelon

wait I just realised what a pain this would be to write into the Turtlèd program

Qwerp-Derp

4:39 AM

It stills outputs infinitely, incing up to 128 and overflowing to -127 over and over again

Destructible Watermelon

that's it its a Turtlèd python 3 python 2 one

quartata

@Qwerp-Derp AT&T syntax looks different

mov eax, var will move the address to var into eax

Destructible Watermelon

well, I think I'll have to change some stuff up a bit

quartata

Have you verified what's actually in var2

Destructible Watermelon

4:55 AM

I made a python 2 and python 3 thing now

now to add the other language

probably Turtlèd, but IDK

Downgoat

@ConorO'Brien do you know if it's possible to overload an implicit string cast? e.g. "" + myClass with toString and all?

Idk, I am just trying to convert long double into string and std::to_string doesn't give full precision

otherwise I'll have to manually specify prescision

@ConorO'Brien The great thing is, 400% compression is pretty normal for Actually vs Python 3

@Pavel in this sense

Pavel

It does say every sequence should have a chance of being output, but not an equal chance.

Do you know if sequences can be removed from OEIS?

xnor

missed that line, looks good

i don't know if sequences get deleted

Pavel

Because if they don't, you can just hardcode the last sequence and pick any value lexicographically before it.

The requirement for future expansion necessitates writing code to validate that the random sequence id is actually valid

xnor

5:59 AM

oh, they are all filled in contiguously?

Pavel

Yep

Starting at A000001 and increasing

xnor

i see

is there any upper bound people can use if they validate the sequence?

Pavel

Every single existing sequence starts with A. This will only change after the 999999th sequence, which doesn't exist yet.

xnor

i.e., someone assumes there will be never more than 10^10 sequences

@Pavel you definitely should emphasize that if answers need to handle it

Pavel

Ok, I'll add that the program can assume that Z999999 will be the last sequence, since it can't be known how they'll handle it afterwards.

xnor

6:02 AM

i see it's in the regex, but it's easy to mmiss

Pavel

Actually, apparently I was wrong about them being filled in in order.

Earlier today I checked oeis.org/search?q=keyword:new&sort=created and found three sequences sorted lexicographically descending, which they aren't now. Must have been a coincidence.

In that case, I actually don't have to support future expansion. On the other hand, I kind of do because generating a random letter is just more code that needs golfing over a random 6-digit integer.

On the other hand, maybe I was right earlier and am wrong now.

Go to any sequence, and try checking the one 1 below it, and the one 1 below that, etc.

The size of a long double is entirely dependent on the compiler

Geobits

The size of a double usually depends on the bartender in my experience.

Anonymous

Since IEEE 754 floats' ulp is > 1 after 2**(digits) (refer to this table for values for digits), you need an integral type whose size is at least digits to store any integer representable by a IEEE 754 float

Geobits

So for a regular double (53 digits), you need at least 53 bits, so int64_t or uint64_t

Downgoat

I was doing a long

Maybe long double is too big for default number type?

Anonymous

A long double can be the exact same as a double (53), an 80-bit value (for which a 64-bit int should still work), or even up to a quadruple (128 bits, so 113 digits, which needs a 128-bit integer)

the thing about ouroborus programs (quine loops) is that only one of the programs does any real work

int64_t is exactly 64 bits. int_least64_t is at least 64 bits. int_fast64_t is whatever the compiler thinks will be the fastest type that is at least 64 bits.

On 64-bit platforms, they are usually all the same type

Once 128-bit platforms start being used, they may not be the same

Look at the 32-bit versions: they're all the same on 32-bit platforms, but int_fast32_t may be 32 or 64 bits on a 64-bit platform, depending on which is faster for the platform

ApacheCommonsLang would be great for golfing in java, except the import statement alone is longer than some existing java submissions.

If you're using a function, you can just return an array instead of printing it

Some questions ask for a complete program.

ApacheCommonsLang has a lot of other features.
