So like can I answer in x86? Is that not considered a programming language.

I think its pretty cool.

TùxCräftîñg

x86 can add two numbers and process primes, so it's allowed

Nathan Merrill

x86 is certainly acceptable

Destructible Watermelon

I was thinking of making a Langton's ant derivative, except I wouldn't be able to program in it at all

TùxCräftîñg

LA is already TC

Destructible Watermelon

@TùxCräftîñg (my brain would hurt too much, and LA has no io)

tatatat0

08:10

Nice! thanks.

TùxCräftîñg

like most CAs, the 'IO' of LA is the initial state (too many abbreviations in this phrase)

Destructible Watermelon

@TùxCräftîñg but that's also the program of LA

and also my brain would asplode if I did that

TùxCräftîñg

hardcoding values is allowed if the language dont have input

Destructible Watermelon

My head would asplode, @tux

I was thinking of making a wimpmode of LA

but I don't know

TùxCräftîñg

otherwise there is also turmites

tatatat0

08:16

Can I assume inputs?

TùxCräftîñg

basically programmable LA

@tatatat0 ?

tatatat0

Like if the input is "setlherjkthsltjsehjlthseljt" could I assume that is at an address?

Destructible Watermelon

@tatatat0 you can assume input is proper according to the challenge

TùxCräftîñg

where is the prime number challenge?

i want to answer it in 6502

Destructible Watermelon

I will find it

111

Q: Is this number a prime?

Believe it or not, we do not yet have a code golf challenge for a simple primality test. While it may not be the most interesting challenge, particularly for "usual" languages, it can be nontrivial in many languages. Rosetta code features lists by language of idiomatic approaches to primality te...

TùxCräftîñg

08:18

kthx

tatatat0

Also, if the challenge asks for an output can I assume an address is the output?

Destructible Watermelon

@tatatat0 I think it would be best if you just looked at this question, for answers like this

7

A: Default for Code Golf: Input/Output methods

Assembly programs may write output to some specified memory location If there are no I/O devices available, an answer might consist of a subroutine that writes its output values to some specified memory location (e.g. write a machine word to $0000).

tatatat0

Thanks

feersum

@DestructibleWatermelon That's no good since x86 has real functions.

You should use a standard calling convention like cdecl or stdcall.

TùxCräftîñg

__fastcall

generally cheaper in bytes

9 % 4 = 5 | 1
9 % 5 = 4 | 4
9 % 6 = 3 | 3
9 % 7 = 2 | 2

nope, the function is entirely borked (left my algorithm, right a % b)

Destructible Watermelon

I think it's actually b>=2*a

it works otherwise, actually

it works iff b<2*a

Cognitive dissonance

In psychology, cognitive dissonance is the mental stress or discomfort experienced by an individual who holds two or more contradictory beliefs, ideas, or values at the same time; performs an action that is contradictory to one or more beliefs, ideas, or values; or is confronted by new information that conflicts with existing beliefs, ideas, or values. Leon Festinger's theory of cognitive dissonance focuses on how humans strive for internal consistency. An individual who experiences inconsistency (dissonance) tends to become psychologically uncomfortable, and is motivated to try to reduce this...

A paraprosdokian (/pærəprɒsˈdoʊkiən/) is a figure of speech in which the latter part of a sentence, phrase, or larger discourse is surprising or unexpected in a way that causes the reader or listener to reframe or reinterpret the first part. It is frequently used for humorous or dramatic effect, sometimes producing an anticlimax. For this reason, it is extremely popular among comedians and satirists.
