CMM: Can I post a stamp instead of an entire save for answers in The Powder Toy?

Ginger Industries

@PyGamer0 Assuming a stamp contains the data used for the answer, I don't see why not

Redwolf Programs

Morning!

Last day before winter break

Ginger Industries

hooray

Redwolf Programs

...why is our early release bell schedule 1st-3rd-2nd-4th

Ginger Industries

PyGamer0

14:29

@GingerIndustries you can assume the stamp contains the answer

Redwolf Programs

Is a stamp in TPT similar to a function?

PyGamer0

yeah

Redwolf Programs

Then it should be fine since we allow functions

PyGamer0

it takes a part of your screen and saves it on the disk

Redwolf Programs

Wow, I can't believe it's already snowing for some people (saw this picture)

@lyxal At least a couple hundred, if you count individual people in the buildings, likely over a thousand

My school district would send out emails every time someone in the school reported they had COVID, which were sent multiple times per day for about six months

Then they stopped that entirely

Because my state's totally-awesome-covid-prevention-scheme is to pretend it doesn't exist and/or actively hinder attempts to slow its spread

PyGamer0

14:40

@RedwolfPrograms o_o i am jealous

Redwolf Programs

@RedwolfPrograms Okay I learned the reason, and it's as beaureaucratic as it could possibly be

They have to take attendance at a certain time to get funding from the state

And that has to occur during 2nd period

How did it take me more than ten minutes to realize I'm sitting next to a life sized cardboard cutout of a grizzly bear

Yeah, what are the criteria for that list, and also for the rooms' lists of frequent visitors?

PyGamer0

15:07

@RedwolfPrograms Redwolf, it's time to take you to an eye doctor.

Aaroneous Miller

I'm in TNB exactly as often as I'm in Vyxal, since I join them at the same time, but apparently I'm only frequently in Vyxal ¯\_(ツ)_/¯

Wezl - a cautionary tale

"frequently in room" is not about time but about messages% IIUC

Aaroneous Miller

hmm

Ginger Industries

redwolf i'm working on your steganography images

How to get my first message?

What is my first message?

Redwolf Programs

@GingerIndustries The llama has the most breadcrumbs left

Hmm, I thought I detected something interesting with 16x16 blocks in your first image, but it's not there in the second

I guess it's a compression artifact

Ginger Industries

@RedwolfPrograms I can give you a tip if you'd like

Redwolf Programs

Sure

(And I'll give one in return :p)

Ginger Industries

@RedwolfPrograms Look for differences between the modified and unmodified versions of the 1st 2 images

you should be able to find them online

Fmbalbuena

How to post question which needs language-specific

Bad idea: Post to CGCC

Bad idea: Post to SO

Redwolf Programs

15:54

The hint for mine: Only one of the color channels is relevant. Look for weird patterns.

Fmbalbuena

Good idea: make a function and post to CGCC with tips question

Redwolf Programs

16:05

Okay, this is looking promising

Unfortunately due to JPG stuff image 1 isn't working properly, but the diff for the second one is showing some interesting stuff

Ginger Industries

i've gotten about nowhere

Redwolf Programs

Steganosaurus, a steganographic image analysis tool I made a little while ago, might help if you're having trouble visualizing the low bits of the image

Fmbalbuena

@RedwolfPrograms AI?

Redwolf Programs

No, it just lets you strip away higher bits, filter by color, and analyze alpha stuff

Ginger Industries

i already ran an alpha scan, guess I'll do it again

Redwolf Programs

16:09

No alpha stuff

Dw

Ginger Industries

just scannin for 70

Redwolf Programs

I think I've got yours just about solved

DLosc

My boss emailed me a link to an article about this language. Looks pretty legit. I might have to try golfing in it sometime. ^^

Ginger Industries

this is difficult

what is this

Redwolf Programs

Random data

Looks like HEIC artifacts

Aaroneous Miller

@GingerIndustries ~~I'm pretty sure that's just a picture of me with some filters~~

Redwolf Programs

I'd recommend starting with the llama

Ginger Industries

its the snow image
with bits set to 1

Redwolf Programs

Yeah, I left the green and blue channels alone

Ginger Industries

i seee

oh

okay

one sec, i think i got it

so signifigant bits on 1 just rounds every pixel to either on or off?

@RedwolfPrograms ^

Redwolf Programs

16:30

Yes, significant bits isn't really useful for this

It's meant for determining what an image would look like if you compressed the number of bits, like you would if you just did a traditional "hide an image in an image" type thing

Ginger Industries

i'm seeing some strange things in this image

Redwolf Programs

Yep, you're on the right track!

Ginger Industries

:)

Redwolf Programs

I see the diagonal pattern thingies in yours, so I'm just trying to figure out how to piece them together into text now

Yes!

Ginger Industries

didja get it

@RedwolfPrograms ^

Redwolf Programs

16:42

Almost, just need to write a bit more decoding stuff and try it on image #3

Ginger Industries

yours is giving me a hard time

i'm trying to get PIl to get each of the 9x9 boxes

Redwolf Programs

Yeah, there's a dot in the top left of most, so they're actually 8x8

Ginger Industries

@RedwolfPrograms oh

now how do I turn that into text

Redwolf Programs

16:48

That's about half the difficulty of the system. My hint would be to look for interesting patterns within the blocks.

grandBagel

@RedwolfPrograms caaaaaac?

Ginger Industries

it looks like the top-left pixel of each cell is always the off color, can I use that safely for calibration?

@RedwolfPrograms ^

Redwolf Programs

No

In some (albeit rare) cases it's on

But it does serve a purpose, and a rather important one

Ginger Industries

like if we're in a red section, will it always be white?

@RedwolfPrograms ^

Redwolf Programs

No

Ginger Industries

16:57

aaaaaaaaaaaaaaaa

grandBagel

@RedwolfPrograms symmetry?

Redwolf Programs

That's a big part of it!

Ginger Industries

it looks like the on colors are 126 and 238, and off are 127 and 206

wait no

Redwolf Programs

What do you mean by on and off colors?

Ginger Industries

the first non-empty set of 8 pixels is 10011111

ah yes, �

or 159

Redwolf Programs

17:03

There's a way to determine which 8x8 blocks are meaningful and which aren't

Ginger Industries

h m m m m

Redwolf Programs

Actually, two of them

Ginger Industries

well first i need to get the 8x8 blocks

currently I have sets of 8 pixels

caird coinheringaahing

CMQ: My blog post is almost done, but I'd like some thoughts from y'all. It's on the impact of CGCC on the worlds of Code Golf, and of programming in general. Are there any things/areas you think that, specifically because of CGCC, have grown, been created, etc.?

For example, I have TIO as one such example, as it was created for CGCC, but has since expanded beyond the site

Redwolf Programs

I was about to mention TIO, yeah

grandBagel

Esolangs in general

Redwolf Programs

Has CGCC had any major impact on the popularity of esolangs?

ninja'd

caird coinheringaahing

Esolangs is one of my main points :P

Ginger Industries

jelly, vyxal, 05a1, apol, etc. wouldn't exist w/o GGSE

or at least not be well known

DLosc

@RedwolfPrograms I don't know about popularity of esolangs, but number of esolangs for sure. I've personally created several esolangs that aren't golf-specific, and I doubt I would've done so had I not been involved here.

Redwolf Programs

Debates about flags /s

caird coinheringaahing

Retina, Hexagony and other very popular ones have been created because of this site

Redwolf Programs

We've helped out with a few OEIS related things I think, but I suppose that's probably not too major of an impact

grandBagel

Which one came first, Pyth or CGCC?

DLosc

17:10

CGCC

Redwolf Programs

CGCC

Well, PPCG at the time :p

DLosc

(or PPCG, to be more accurate :P)

Redwolf Programs

haha, I am ninja

caird coinheringaahing

@RedwolfPrograms Oh, good point, I forgot about the meta post about CGCC's impact

DLosc

Which one came first, Pip or Pyth? (both are based off Python)

DLosc

Pyth, I'm pretty sure

grandBagel

Redwolf Programs

Do y'all pronounce it "pith" or "pie-th"?

Ginger Industries

Pode Polf Cack Gxchange

grandBagel

@RedwolfPrograms "pie-th"

Ginger Industries

17:11

pie-th

caird coinheringaahing

@cairdcoinheringaahing This one

@RedwolfPrograms "pie-th", but its supposed to be "pith"

grandBagel

@cairdcoinheringaahing I personally prefer pie-th.

DLosc

@RedwolfPrograms "Pith," but only because I've been told that's the correct way

Aaroneous Miller

@GingerIndustries In the APOL repl, parsing breaks if you try to put brackets or parentheses in strings (e.g. p(")") or p("["))

Ginger Industries

@AaroneousMiller Okay, I'll take care of it at some point

DLosc

17:13

@grandBagel Pyth appeared in 2014, Pip in 2015

Ginger Industries

okay, we've got my algorithm outputting 8x8 blocks

Redwolf Programs

For your stegano cop, I'm still stuck on turning the lowest three bits of the diagonal lines into text

I've gotten it to print l, but then it's just garbage after that

Ginger Industries

¯\_(ಠ_ಠ)_/¯

Redwolf Programs

Do I have to do it on the modified copy or the diff itself?

Ginger Industries

i will tell you this much, I ran the text data through an encoding algorithm

DLosc

17:15

@DLosc If it were up to me, I'd say "pie-th" and "vixl." But the language creators insist that it's "pith" and "vie-xal." ¯\_(ツ)_/¯

Redwolf Programs

I say "pith" and "vixl" because I'm to lazy for long bowels

5

uh...vowels

Ginger Industries

APOL is pronounced "ay-pawl"

@RedwolfPrograms excuse me

wait, some of the 8x8 blocks are part of the llama

does the top-left pixel describe what is and isn't llama?

Redwolf Programs

Close

Aaroneous Miller

I say "Vie-xal" because I don't pronounce it wrong.

Redwolf Programs

It describes, in a way, what is and isn't a block containing data

Ginger Industries

17:19

there are 3 types of blocks: Empty, Non-empty, and llama

Redwolf Programs

Not really, that's a bit of a false distinction

There's modified (data-containing), and non-modified

Ginger Industries

there are 2 types of blocks, content and garbage

just like reddit posts

College spam email from yale lol

Redwolf Programs

I suppose that's a step up from Montana State or whatever

Why do all college spam emails offer "[x] free resources"

Ginger Industries

okay so the problem I'm having is as follows:
You can see that in the white areas each empty block has a red pixel and the rest is white
but in the red ones (like in the cloud) empty blocks have a white pixel with the rest red
how do I tell between red and white blocks?

@RedwolfPrograms ^

Redwolf Programs

This is probably too big of a hint, but try looking at the parity

Ginger Industries

just looked up what parity is

i see

so that corner bit is a parity bit?

Yep!

In as few characters as possible in t-sql, return 100 rows containing the phrase 'Have a great Christmas'

DLosc

@NewPosts Hmm. Not sure how I feel about this one.

Ginger Industries

@RedwolfPrograms unfortunately, PIL's posterize method works on most signifigant bits instead of least

Redwolf Programs

I'm trying to find something useful to provide feedback on to the OP, but I don't know what's wrong with it precisely

It's just...not a good challenge for this site

DLosc

It's language-specific and pretty trivial, but neither of those are disallowed, and I'm not convinced it's a dupe of Hello World because the main challenge is the "return 100 rows" aspect.

Ginger Industries

¯\_(ಠ_ಠ)_/¯

Redwolf Programs

17:56

It's probably pretty trivial to write an optimal answer for

DLosc

IDK, maybe my T-SQL isn't up to par, but I'm not sure what the best approach would be

Ginger Industries

@RedwolfPrograms How exactly does your posterizing algorithm work

Redwolf Programs

The low bits one?

If you mean the one when you click 1, it's just modding the byte value by 2

Ginger Industries

@RedwolfPrograms so just take the brightness value and modulo 2 for each pixel?

@RedwolfPrograms nvm, got it working

thejonymyster

feedback? i wouldnt be surprised if its a dupe but all i could find is this which is not quite the same

not sure if good or bad amount of overlap loll

DLosc

I think that's a dupe--on a cursory reading, any of the Random Derangement answers would also be an answer to your challenge, and most of them would probably require a trivial amount of golfing to become optimal answers to your challenge.

Unless I'm missing something.

Oh, I see, there's a difference on whether the input can have duplicates.

thejonymyster

yea but im not sure if that difference matters in implementation

it at least means you cant just rotate the sequence

but considering the random derangement ones have to get all possible derangements, theyd have to try most orders anyway

Redwolf Programs

@RedwolfPrograms Now that the question has an answer, I've concluded that it's not trivial after all and upvoted it.

Redwolf Programs

@GingerIndustries I've still made no progress on yours :/

Wezl - a cautionary tale

@grandBagel similar: [...Array(100).keys()].map(a=>a+2)

(results in 2, 3, 4 ... 99, 100, 101)

thejonymyster

array(n) blew my mind when i first found out abt it

grandBagel

DLosc

Redwolf Programs

You can do base64 in four bytes, but range? Who uses that?

Ginger Industries

okay, the first cell w/ actual data in it contains the binary data:
0110000011100000110000001100000011000000110000001100000011110000

w/ byte 1 being parity

okay, so we're using odd parity

Redwolf Programs

@GingerIndustries That doesn't seem correct

Ginger Industries

@RedwolfPrograms it isn't i screwed up

Redwolf Programs

That's just part of a cloud I think

Ginger Industries

and still odd parity

filter() them.

Ginger Industries

i will

still garbage

grandBagel

@GingerIndustries did you decode?

@grandBagel working on it

grandBagel

@GingerIndustries or try brute-forcing the encoding

Ginger Industries

@grandBagel how?

@GingerIndustries for encoding in ["utf8", ...]: if the decoded message is not garbage: print it out

Redwolf Programs

@grandBagel Because x<y>z isn't valid in JS

You can't chain comparisons like you can in Python

grandBagel

@RedwolfPrograms No, I was doing i<ternary_expression
