Radvylf Programs

I just came across the strangest thing

thejonymyster

oh i forgot to expand "com" to be "comma"; in many cases it acts like a literal comma lol

oh do tell, radvylf

Radvylf Programs

I made a pretty simple mistake while writing some stuff involving a 2d grid

thejonymyster

2:23 AM

everyone point and laugh

Radvylf Programs

Instead of array[x + y * width] >> 2, I just wrote array >> 2

And this array was about 100k items

And here's the weird part

It made the program extremely slow

Even though, as far as I'm aware, bitshifting an array is entirely meaningless

thejonymyster

yea i was about to say what would that even do

Radvylf Programs

Ohhhhhhhh wait

thejonymyster

what lang, some c-like?

Radvylf Programs

dumb type system strikes again

It's stringifying the whole list

thejonymyster

2:25 AM

lmao

Radvylf Programs

Then casting to a number and bitshifting it

Gotta love JS

thejonymyster

LOL thats actually hilarious

Aiden Chow

Bruh what, why js do eat lolol

That*

thejonymyster

wwjsd

Aiden Chow

Autocorrect smh

Steffan

2:26 AM

that's just how js works

coerces everything to whatever it needs to be

so like [3] == 3

Radvylf Programs

yeah, but coercing a typed array to a string then again to a number is a pretty weird behavior, even for JS

Steffan

that's why you should always use ===

Radvylf Programs

@Steffan That's kinda a bad example

Steffan

i know

[] == 0

thejonymyster

@Steffan how would that save you from bitshifting an array :P

Steffan

2:28 AM

it wouldn't lol

why on earth would you want to bitshift an array though

thejonymyster

array language brain took over

Steffan

i guess it could vectorize

but mainstream languages never do that

Aiden Chow

I could see myself accidentally trying to bitshift an array lol

Radvylf Programs

@Steffan The point is you wouldn't :p

I still managed to do it by accident though

thejonymyster

clearly it should have the same effect as array.shift() twice

Aiden Chow

2:32 AM

What’s array. Shift()?

Radvylf Programs

Pops from the front

thejonymyster

array=[1,2,3] //hello im an array
console.log(array.shift()) // 1
console.log(array) // [2,3]

Radvylf Programs

@thejonymyster My first thought was actually "did they add experimental syntax sugar for shifting" lol

thejonymyster

lmao

verbose language where all the verbose keywords are still just combinations of symbols trying to convey their meaning to you

like emojicode but without the emojis

lyxal

3:11 AM

@thejonymyster so basically everything useful is going to be *<command>?

thejonymyster

not everything :P

but still, whatcha gettin at

lyxal

so if I want to add two numbers and then subtract three I'd need to do something like *+#3;*-?

thejonymyster

something of that sort, its not stack based though

lyxal

thejonymyster

correct response

lyxal

3:23 AM

congratulations you've invented a SBCS language

thejonymyster

lolol

lyxal

If I need to use *<other half byte> for most things, you might as well use the full byte

because then you get more command options

thejonymyster

its really more akin to a variable width encoding

lyxal

yeah but you lose out on a lot of command options

thejonymyster

since the increment for stuff is still half bytes and not full bytes

lyxal

3:24 AM

*<other half byte> only gives you 16 operators

using the full byte gives you 256

minus syntax and literals

thejonymyster

well "using the full byte" doesnt come from thin air, i have to change everything else too :P

lyxal

that's my point

thejonymyster

dont wanna :sob: dfsg

ill think about it. maybe ill make soemthing good for once :peace:

@lyxal I don't know yet, still prototyping. Not even sure if this idea is viable yet, emanresu pointed out some issues with my approach

lyxal

only your sampling approach

not the actual tree generation as far as we know

maybe you got unlucky and got all 45 answers with ⇧

which skewed the results maybe

mousetail

I found a mistake, even though I requested a page size of 100 the api is returning only 30 responses at a time. Even though the docs state 100 is the max value

got 1672 responses now with a page size of 30 so that's a lot better

lyxal

@mousetail well if you ever want the encoding to be officially vyxal recognised, just ping me and I'll make it happen

mousetail

Thanks, I'll let you know

mousetail

6:47 AM

@lyxal Am I correct that you can always replace line breaks with spaces and preserve meaning?

lyxal

no

\
# comment here to preserve newline

that pushes the string "\n" to the stack

Hmm ok sad

and once #1424 is merged, newlines will have even more meaning

I won't mess with it in that case

TIL you don't need parenthesis to define tuples in python.

x=1,2 works

You can also use x=1, to define a tuple with 1 element

does that mean there's a 4 byte saving on average?

Nearly 4 bytes yes

with 100 byte standard deviation lol so the average is a bit useless

Seggan

@RadvylfPrograms i think youre misunderstanding what im doing

the more common a digit, the higher ill stick it up on fig's huffman tree

im not talking abt digit runs here

lyxal

@mousetail what's the average byte save on shorter programs?

mousetail

Define short and I can get you the answer

lyxal

< 30 bytes

also, when you have the length of the compressed program is that in raw bits or is further compression applied?

Seggan

@lyxal thats short?

mousetail

12:31 PM

@lyxal Length is bytes, including padding 0s at the end

lyxal

@Seggan that's a range where huffman would probably give a slight edge over jelly/05ab1e/etc

@mousetail interesting. What are the results without the 0s?

because I'm sure base-255 encoding could get those byte counts down a bit more

mousetail

base255 encoding?

Seggan

like arn

lyxal

@mousetail convert the bits to base 10, convert that to base 255 using the vyxal codepage as the alphabet

mousetail

I already use every bit, base 256 encoding

including null bytes

I strip any null bytes from the end though, they are implied

lyxal

12:34 PM

base-255 encoding/compression works a little differently to that

mousetail

lower base will always be worse though right?

lyxal

base-255 doesn't care about how many bits are used

it's more how many "digits" are in a number

mousetail

Can you link me something about it? My google skills are failing me

lyxal

github.com/Vyxal/Vyxal/blob/main/vyxal/elements.py#L539

say you have a number like 149238032. That requires 9 bytes to store as a program (one for each digit). If you convert it to base 16, you get 8e53110 which is 7 bytes, which is an improvement. If you convert it to base 36 (using 0-9A-Z as the alphabet) you get 2GUOSW which is 6 bytes - a 3 byte improvement over the original number

mousetail

this is only needed because you need a terminator character right?

lyxal

12:40 PM

converting it to base 255 gives ⟨ 9 | 0 | 22 | 47 ⟩ as a list of digits which, when indexing into the vyxal codepage gives «λæ0

mousetail

so you need to reserve one code point

lyxal

@mousetail no

huffman encoding returns a series of bits, yes?

mousetail

yes

lyxal

treat that series of bits as a base 10 number

and then convert that base 10 number to base 255

and that's the program

and that could be even shorter

mousetail

that would cost one extra byte every 255 bytes right?

lyxal

12:41 PM

tell me, what's the bit sequence for ₁ƛ₍₃₅kF½*∑∴ without padding?

mousetail

Should be 88 bits in a SBCS

lyxal

but what's the exact bit sequence

in your encoding

mousetail

[1, 0, 1, 1, 1, 1, 1, 0, 1, 0, 0, 1, 0, 0, 1, 0, 0, 0, 0, 1, 1, 1, 0, 1, 0, 1, 0, 0, 0, 1, 1, 1, 0, 0, 0, 0, 0, 0, 1, 1, 1, 1, 1, 1, 1, 1, 0, 0, 0, 0, 0, 1, 0, 1, 1, 0, 0, 0, 1, 0, 1, 0, 1, 1, 1, 1, 0, 1, 1, 0, 0, 1, 0, 0, 1, 0, 0, 1, 1, 1, 0, 0, 1, 0, 1, 0, 1, 1, 1, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0]

Or in bytes b"\xbe\x92\x1dG\x03\xfc\x16+\xd9'+\xc0"

lyxal

odd, that's somehow longer than the original program

mousetail

That happens sometimes

Every compression method has this issue, it makes more common programs shorter at the expense of rarer programs

I do pad 8 extra 0 bits at the end

lyxal

12:46 PM

so is that 13 or 14 bytes?

with padding

mousetail

12 bytes

I remove 0s at the end when converting to bytes

lyxal

so the list becomes

[1, 0, 1, 1, 1, 1, 1, 0, 1, 0, 0, 1, 0, 0, 1, 0, 0, 0, 0, 1, 1, 1, 0, 1, 0, 1, 0, 0, 0, 1, 1, 1, 0, 0, 0, 0, 0, 0, 1, 1, 1, 1, 1, 1, 1, 1, 0, 0, 0, 0, 0, 1, 0, 1, 1, 0, 0, 0, 1, 0, 1, 0, 1, 1, 1, 1, 0, 1, 1, 0, 0, 1, 0, 0, 1, 0, 0, 1, 1, 1, 0, 0, 1, 0, 1, 0, 1, 1, 1, 1]

?

mousetail

Yes I think so

thejonymyster

2 extra bits over the original :-)

lyxal

my base 255 idea comes out to ¬⅛HuÞ†ǐX⁋dṫ⁋ which is also 12 bytes

thejonymyster

12:49 PM

i still dont understand why 255 and not 256 :-0

mousetail

@thejonymyster this

I don't understand how a lower base could ever be better

lyxal

well you see, it's because I forgot that the encoding doesn't need to be surrounded by any characters like usual base-255 compression does

mousetail

I do actually have a "end" character but it's purposefully made of only 0 bits and I imply a infinite number of 0 bits at the end

thejonymyster

nice

py3programmer

@lyxal of course if you use base 149238032 you could possibly store the number in 1 byte

ig

thejonymyster

1:01 PM

@py3programmer me when i definitely know what a byte is :P

py3programmer

wait a minute

which is the lowest possible base (assuming we have enough characters) that can store the number 149238032 in a byte?

mousetail

149238033 right?

thejonymyster

there is no base which can store any number higher than 255 in one byte

mousetail

if you have very wide bytes

thejonymyster

Did you mean: character

mousetail

1:03 PM

bytes are not always 8 bits on all systems

nowadays they mostly are but there used to be variation

py3programmer

yes

thejonymyster

crazy

imagine trying to interface with a machine that doesnt agree with how many bits are in a byte

py3programmer

quantum computer?

Radvylf Programs

On CGCC though, "byte" always refers to exactly 8 bits of information

py3programmer

no wait that operates on qubits

mousetail

1:04 PM

There are barely 8 qbits on the earth

thejonymyster

make more then smh

Ginger

is it "qubit" or "qbit"?

thejonymyster

cube-it

mousetail

damn we made the same joke at the same time

thejonymyster

1:05 PM

remember when some of us tried to pronounce "lyxal"

Bubbler wrote "licks-all"

thejonymyster

lets all agree never to ~~be creative~~ pronounce things again

mousetail

Is there another way to pronounce it?

Radvylf Programs

@py3programmer That's still how I usually pronounce it lol

py3programmer

i dont think so

thejonymyster

apparently its supposed to be "likes all" but like

Radvylf Programs

1:06 PM

@mousetail The correct pronounciation is "like-sall"

thejonymyster

its obviously licks all yeah

py3programmer

me too @thejonymyster

Radvylf Programs

Likewise for Vyxal ("vike-sall")

mousetail

That's the main reason I call it lyxial since it sounds less disgusting

py3programmer

if you pronounced vyxal similarly to lyxal it'd be vicks-all

thejonymyster

1:07 PM

imagine just adding a letter into any word you dont like the pronounciation of

mousetail

I do that subconsciously a lot

My brain is like "that can't be right" then makes something up without telling me about it

thejonymyster

@py3programmer yeah, to me it makes sense, its like vixen

ah im at work at the moment though, no firefox here :cry:

mousetail

tooltip covers the keyboard though

I'd move it down a bit

im making a tree for Fig lol

i thought i said that

how are you handling digraphs?

yesterday, by Seggan

@thejonymyster this is what ive always been looking for

mousetail

3:18 PM

@Seggan Oops my bad

I have a few alternate trees depending on the previous character

Seggan

so digraphs are a single node?

mousetail

no

the first char of a digraph starts a seperate tree

Seggan

ah

mousetail

I'll try single node digraph mode though to see if it's better

Seggan

my plan is to have a "master tree" that has digraphs close to the top so they dont cost as much

as fig doesnt have too much monograph space

Q: Is this a refinement?

A partition of a list \$A\$ is a way of splitting \$A\$ up into smaller parts, concretely it is list of lists that when concatenated gives back \$A\$. For example [[1],[2,3],[51,6]] is a partition of [1,2,3,5,6]. The trivial partition is a partition that "splits" the list into only one piece, so ...

Take a list of 2-digit hexadecimal numbers as input, and output the binary value, replacing each 1 with an 'X', and each 0 with a space. For example Input = FF, 81, 47, 99. FF = 11111111 in binary, so print XXXXXXXX 81 = 10000001 in binary, so print X X 47 = 01000111 in binary, so print X ...

Anyone else constantly get hamming codes and huffman coding mixed up?

thejonymyster

cant say i have, no

i wonder how one might combine these two concepts however

some kind of ham-man code

Radvylf Programs

@thejonymyster wait really

am I just bad

caird coinheringaahing

@RadvylfPrograms Nope, not even once

Radvylf Programs

I can never remember more than one of those names at once

and it tends to be the one opposite to what I'm currently in need of

youre thinking of hammurabi

but make sure not to ham ur rabbi

Radvylf Programs

Oh hey I just learned about that guy in art history class today

thejonymyster

hammurabi code golf. "a byte for a byte"

@RadvylfPrograms i keep thinking its hoffman coding

@RadvylfPrograms i was so close to asking "did you never hear about him in high school" until i remembered you're in high school and art history is just an actual ap class for some reason

Many APs are dumb

CS AP was free points for me though which was nice

cs ap is hopefully free points for anyone

I'm taking 7 AP classes this year

Some are definitely dumb

CMM: should I edit out the in PHP (or anything else, for that matter) from the title of codegolf.stackexchange.com/q/9165/107299?

caird coinheringaahing

I don't think so

If it was just "in PHP", probably, but it's clear that it's language agnostic

Seggan

yeah but imo it just adds noise

caird coinheringaahing

Our titles are rarely the succinct "summarise the problem" that the rest of the network has

It's been unedited for almost 10 years, I see no reason to edit it now

Seggan

true

thejonymyster

@cairdcoinheringaahing how about the noisy factor? every time ive looked at it i didnt like it :P

caird coinheringaahing

8:26 PM

Is the "in PHP (or anything else, for that matter)" the noisy bit to you, or is it the BASIC code?

thejonymyster

only the (or anything else for that matter) , and maybe change in to from

theres gotta be a more terse way to say "by the way this is a regular challenge that doesnt restrict this to one language"

since thats basically the standard

or sure get rid of the whole in php ...

if youre wondering what language its from you can find out by like, clicking in

hold on ill clarify in a sec brb

Radvylf Programs

@cairdcoinheringaahing Wouldn't the opposite make more sense?

Seggan

@thejonymyster this

Radvylf Programs

in PHP (or anything else, for that matter) is 100% noise

It is entirely meaningless

Seggan

Radvylf Programs

8:31 PM

Whereas in PHP communicates a meaningful restriction

thejonymyster

@RadvylfPrograms yeah thats what i was about to get at

caird coinheringaahing

¯\_(ツ)_/¯ Sure I guess. Just think that it's an old question, no harm is leaving it that way

thejonymyster

all "(or anything else for that matter)" serves as is the clarifier, for the "in php", but the "in php" is just trivia and not necessary

caird coinheringaahing

Y'all aren't even close to the most zealous editors the site has ever had, and even they left it alone :P

thejonymyster

if it were phrased like "PHP's (code snippet)" itd probably work without losing information

^^ lol

CMC: given two pairs of points [(a,b), (c,d)] and [(e,f), (g,h)], determine if the line from (a,b) to (c,d) intersects the line from (e,f) to (g,h). you can assume they have different slopes, and that none of the four given points are equal, and that the intersection (if it exists) wont be at one of the points

caird coinheringaahing

8:41 PM

@thejonymyster Can we assume that no triple will be colinear?

thejonymyster

hm, sure

yeah that makes sense, since the only times they would be intersecting would be illegal, making it an edge case

Returns the coordinates of the intersection else nothing.

@thejonymyster how can a point be equal?

is the point (6, 2) equal?

caird coinheringaahing

I'm guessing the "to each other" is implied
