@RadvylfPrograms Most of the time it's usually done by turning a computer duster upside-down and spraying the extremely cold mist on the memory sticks, although a lot of modern cold boot attacks don't do that and instead do a cold reboot into a custom OS with a low memory footprint which then dumps memory. In one case, the BIOS was modified to contain a custom coreboot payload that exfiltrated memory over serial! Liquid nitrogen is usually overkill.

@RadvylfPrograms are there supposed to be tests too?

Bubbler

Can I extract the bit pattern of a given float as an integer?

Register machine sounds appropriate

Unlimited registers but maybe take the number of registers used into account in scoring?

Sʨɠɠan

@DialFrost wdym "wdym"?

that's how you compile it

then ./a.out

Sʨɠɠan

i don't know what you're confsued about either

if you want to compile it then run that

DialFrost

1:56 AM

wait nvm i got it running

btw @Sʨɠɠan how did you get 30 bytes for tcl in quine? (hint maybe?) [you owe me a hint for that crystal solution you found too earlier ;)]

Radvylf Programs

2:09 AM

@Bubbler I don't think that'd be a huge issue, since you're limited to n+2 registers if you're using n instructions (and for any practically useful algorithm it'd probably be less than n), and any solutions that're using beyond like, a couple dozen registers are probably not going to be competitive.

Sʨɠɠan

2:38 AM

@DialFrost considering only 3 people have it, i'm not giving any hints except that you can find 33 bytes online

DialFrost

2:53 AM

@Sʨɠɠan sigh

Whenever John Skeet asks a question ofc its gonna skyrocket

Sʨɠɠan

@emanresuA makes perfect sense to me :P

DialFrost

@Sʨɠɠan I highly doubt it cuz I searched a lot but if you say so lol

@Sʨɠɠan if you could find 33 bytes online, then its abit sus that no one has 33 bytes rn

@Sʨɠɠan you still owe me a hint for the crstyal solution buddy :3

@DialFrost it comes up top in search for me

DialFrost

3:25 AM

@Sʨɠɠan then ur computer is hacking :D

Sʨɠɠan

i'm also surprised no one else has it

maybe you don't know how to use google

i'm known for finding things in google that no one else can find

DialFrost

the top search i got is some random tcl-lang website which doesnt even use the proper printing to qualify as a quine

@Sʨɠɠan hehe

Sʨɠɠan

honestly i just did a two word search and it's top

DialFrost

so did I

and I got tcl-lang.org

Sʨɠɠan

that's the exact page that your'e looking for

DialFrost

3:26 AM

????

It gave me a 47 byte solution

Sʨɠɠan

it's literally on the page

DialFrost

not a 33 :p

@Sʨɠɠan no its not

there is not a single solution on this page where it is 33 bytes

unless we're talking about different pages on the same site

Ru sure its Tcler's Wiki?

Sʨɠɠan

but there is a 34-byte one that you can fix to be 33. it won't even work as 34

you can't just copy and paste it in

DialFrost

I know

but including the printing will lengthen it

or am i being very dumb again

Sʨɠɠan

printing will shorten it :)

DialFrost

3:37 AM

If we're thinking about the same 34 byte solution then not for me lol

I got 47 from the 34 by printing

Sʨɠɠan

you kind of have to understand how it works

then you're doing it wrong

DialFrost

@Sʨɠɠan but i got it right!

:3

@Sʨɠɠan but ... but you have to use puts! that'll lengthen it!

@Sʨɠɠan you have got to be kidding

Sʨɠɠan

you don't add puts, you delete something and add puts

anyway, i'm done giving hints

DialFrost

mkay thats fine

@Sʨɠɠan ~~More useful than Jo King's XD~~

DialFrost

4:07 AM

@Sʨɠɠan for clarification what does \{ \} in join {{} \{ \}} mean?

Sʨɠɠan

string

ah, no wnoder

if that's the one your looking at then it's the wrong one

you do get 47 by adding puts to that

DialFrost

4:31 AM

@Sʨɠɠan shoot

is the real 34 one have something to do with apply?

wait nvm

I got 33 bytes! yay

I'm shocked how I didn't see it

doing some optimality theory homework about factorial typology, and since we're making a point of not really considering domination relations with no observable effect, it occurred to me that the actual rankings we're talking about are a bit more than factorial
and then i realized there's *definitely* some challenge we had here on main about sequences which start with 1 then build rightwards with any n only being permitted if n or n-1 is already in the sequence
but i cannot remember what it would be called

@Sʨɠɠan that 33 -> 30 is so fucking stupid, i didn't know you could do that

DialFrost

@JoKing shit jo king alr found it

i still havent

OH

found it

Jo King

aww, i didn't get to give a useless hint this time

DialFrost

@JoKing lmao

i started deleting random 3 bytes and found it on the 2nd try

i was like wtf

@JoKing sigh ive always wanted a diamond :3

Jo King

maybe try one of the less used langs, i have a few diamonds in lua and elixir

DialFrost

6:15 AM

I have no idea how to use those

Btw how did you get 31 bytes for quine in python? Ive got 32 only

Unrelated String

elixir is fun

DialFrost

@UnrelatedString nah

6:35 AM

@Sʨɠɠan how'd you get 160 bytes for java quine?

I only got 172

@JoKing like in a more used lang

Bubbler

@DialFrost ...good luck

DialFrost

@Bubbler why? :3

oh well i just want a diamond in anything :3

Bubbler

if anything, try some hard holes

and/or more recent holes

DialFrost

@Bubbler but...but i cant solve them

i cant solve like half of the 81 holes

Bubbler

people already spent a ton of time on easy old holes, so the current solutions are already optimal with like 99.99% chance

DialFrost

6:48 AM

especially the math ones, e.g. calculate 1000 digits of e

@Bubbler still...

Bubbler

no, there is no hope there, I can tell based on my own experience

diamond is diamond for a reason

Jo King

you could find a novel way of approaching the problem that suits the language

DialFrost

@DialFrost these stump me

@JoKing lol

Jo King

i'm still amazed my van eck diamonds in php/perl are still holding

Bubbler

for me it's intersection in python

DialFrost

6:54 AM

@JoKing congrats

Jo King

the majority of my diamonds are actually in ><> against single digit other golfers, of which at least half have hardcoded the output

DialFrost

@JoKing problem is I always find simple solutions that always are too long to win

@Bubbler this one got me stumped hard

either 2 things are going wrong: 1. my input getting and setting to integers is too long 2. my calc is too long

but by 20 bytes??? has to be both im assuming

Bubbler

7:10 AM

If this makes you feel better: the top score was 121 bytes for quite a while

DialFrost

not helping lmao im at 132 :3

Bubbler

just two bytes off and you can join the majority of people

DialFrost

the problem is my code is hard to golf due to its structure

Bubbler

then try something different, there are many ways to solve the problem

DialFrost

@Bubbler i only found 1 in 1 week :(

before giving up

Bubbler

7:23 AM

then spend more time thinking about it :P

DialFrost

i do! But everything I try always goes back to the same dumb solution

no, a diamond is a gold without ties

especially for easy challenges

Bubbler

don't forget the byte counting problem

DialFrost

7:28 AM

@Bubbler ?eh

Bubbler

if you can't accept ƛ is two bytes, don't think about adding it to code.golf

DialFrost

@Bubbler thats fine no?

as long as the same rules applies to everyone im fine with any language, especially a golf lang

Bubbler

well then ask other vyxalers then

DialFrost

@lyxal bubbler has a question for you lol

Bubbler

CMP: Would you still golf in Vyxal/Jelly/05AB1E/whatever-SBCS-golflang if the byte count is measured in UTF-8, not SBCS?

DialFrost

7:31 AM

@Bubbler yes (i dont see whats wrong with it)

emanresu A

It's... annoyign

Bubbler

the problem is more like, some single-byte builtins are suddenly golfier than the others, which forces you to think about tradeoffs not considered when designing the language

emanresu A

Having 1 command = 1 byte means that generally, the simplest solution is also the shortest

Unrelated String

7:51 AM

i'd probably stick with jelly until a more utf-8-friendly substitute with otherwise similar syntax and builtins rolled in

because some builtins would be inordinately expensive and while there might be a bit of fun to be had figuring out which are actually sometimes not worth it it would get old fast

lyxal

8:11 AM

@Bubbler probably. It's sometimes fun utf-8 golfing

code.golf would be a good candidate for utf-8

Something like week.golf or here on the other hand would be annoying with utf-8

DialFrost

@lyxal ye

lyxal

After all, the finite number of holes on code.golf mean that once a short sbcs solution is found, it's just finding that solution

Utf-8 golf means there's 2 layers of optimisation to keep activity going a little longer

Bubbler

that's an interesting point

DialFrost

with no googling lol

That sounds like a "creativity-to-think-up-stuff" issue

" As mentioned in the question statement, input is represented by manually changing the state of the automaton at a certain generation."

One of the comments

mousetail

It's very ambiguous

Especially for very simple challenges

Where taking input is like 90% of the challenge

py3_and_c_programmer

If that's what you say, I guess the only reason tetris was able to be implemented was because you weren't around to give a close vote :p

Plus I was wondering if your statement was actually true

"wondering"

Tetris is different because there is singificant amount of logic other than IO, so even if the IO required is extremely specific the result is still impressive

so people be like "nah this guy is lying"

mousetail

Why not try another cellular automata like wireworld? It's similar to GOL but makes it a lot easier to store things thus say "the value in this register is the output"

py3_and_c_programmer

Speaking of cellular automata... I was thinking of an idea where each cell has color, in 3 parts, red, green, and blue. Each cell sets all 4 diagonal cell's red component to its red component, north and south cell's green component is the center cell's green component, and for east and west cell's blue component is the center cell's blue component.

But I'm trying to figure out to create peace in an overlap

@mousetail then mark Valentine's of next year. I should be done by then

There needs to be a condition, otherwise the patterns will be boring

There's no interaction between the channels though right?

So it's just 3 very simple automata overlayed

py3_and_c_programmer

what happened to my comment bar? It flipped?

why

Now it's normal

@mousetail exactly

But it creates a ripple effect

which I hate

mousetail

If you hate it why did you create the idea?

py3_and_c_programmer

@mousetail That would be like asking John Conway that if he hates calling the glider the glider why did he call it the glider?

mousetail

Yes I would ask conway that, that's just dumb

py3_and_c_programmer

@mousetail well it's just a consequence of having some rules

mousetail

9:18 AM

You can regret your choices but at least at some point you need to have thought they where a good idea

py3_and_c_programmer

@mousetail fine forget the idea then

mousetail

@py3_and_c_programmer But why create these rules if you think are so boring? Why even think about them? Of course you may have a idea but find out later it's bad but then you can just discard it and stop thinking about it. Or you can think it's "nearly" interesting but you just need to change it a bit.

py3_and_c_programmer

@mousetail it's a consequence

but the rules weren't boring

are they?

mousetail

Maybe not. You said you didn't like them

py3_and_c_programmer

I said I didn't like the consequences

namely a ripple effect that makes my automata look like Replicator

mousetail

9:23 AM

That's because you don't have any interesting rules

Though I think in it's current form you may be able to use it to create a glitchy effect on a image

since the colors will blur in different directions

py3_and_c_programmer

Actually what I think is that It'll pretty much look like this:

please hold on, sockpuppet is trying to find an image...

Taken from scratch.mit.edu/projects/55315592

awkward

mousetail

Would look more like this though right?

Blured with colored edges

py3_and_c_programmer

Not blurred

where did I mention blurred

mousetail

I assume when there is a conflict you mix the two sides

so it would blur

py3_and_c_programmer

> But I'm trying to figure out to create peace in an overlap

so... well probably I'll just use a blur

is probably how I want it to look like

though I don't need the scrolling and the flashing imagery

mousetail

9:33 AM

That's not at all like the rules you described

py3_and_c_programmer

> though I don't need the scrolling and the flashing imagery

rules didn't apply to that one

mousetail

I mean your rules won't create rectagles

py3_and_c_programmer

Professional tag is played indoors

Trick is to play on a field less than 25m across

py3_and_c_programmer

@mousetail our version of tag is "get humiliated if you're tagged else escape"

@mousetail but in the end you'll end up running more than 25m

well its a trick so okay

but who else will you play with

mousetail

I can't run more than 25 from my starting position, total distance doesn't matter.
