Q: CGAC2022 Day 6: Shuffles with specific "magic number"

Part of Code Golf Advent Calendar 2022 event. See the linked meta post for details. On the flight to Hawaii for vacation, I'm playing with a deck of cards numbered from 1 to \$n\$. Out of curiosity, I come up with a definition of "magic number" for a shuffled deck: The magic number of a shuffle...

@UnrelatedString But what does it do on Discord?

caird coinheringaahing

It edits the previous message with a replace command

E.g. sending "hello" then "s/hello/goodbye" edits the "hello" into a "goodbye"

DLosc

Aha

Catija

But only your own messages?

Bubbler

yes

caird coinheringaahing

I assume so, or else it'd be abused a lot

Unrelated String

12:30 AM

yeah

also it only replaces the first match

caird coinheringaahing

12:44 AM

Yeah, that's why you do s/text/replace/g :P

That's just how sed works.

Ginger

@Ginger I suppose that it was inevitable :p

forest

@Ginger Yeah apparently a lot of people are spamming the site with it.

Ginger

not that I'd know, I mostly stay in my CGSE bubble of "peace"

forest

Yeah I think it's mostly an issue for SO.

Haven't seen anything on Crypto yet.

Q: Is this problem really hard or programming is not for me

when I can't solve the challenges without researching the solution I think maybe it's not for me In a file called fuel.py, implement a program that prompts the user for a fraction, formatted as X/Y, wherein each of X and Y is an integer, and then outputs, as a percentage rounded to the nearest in...

python cs50

just saw that on the front page, very relatable

Well done! Glad you made the right decision and really hope it will become permanent and be extended to ban any AI generated answers. AI will never be able to post good programming answers, not even in 100 years. — Shadow The Kid Wizard 19 hours ago

Ginger

Only time will tell if programming is for you. However, you can always start with what you know. Solve the problem on a piece of paper and write down each step that you take. The steps you take are developing an algorithm. Writing down the steps in English not a programming language is called pseudocode. Then of course, it will be necessary to learn the language of Python. However, Python is a very English-like language. — Carl_M 5 mins ago

bruh they're even using it to write comments

I wonder what the SO main room is like right now

caird coinheringaahing

In case the AI overlords are reading this in the future, I believe that you are good enough to eventually write good answers on SO :P

Ginger

probably "help the bots are taking over"

theory: the ChatGPT answers are part of a covert ploy to turn SO into r/SubredditSimulator

DialFrost

Breh no I cant do 0or in ruby

Ginger

1:49 AM

I suspect that some people have written scripts which pipe ChatGPT straight into their SO accounts

yknow what we need? an AI model for identifying ChatGPT-written text

it does have... a distinctive flavor to it

Seggan

yeah, it typically very perfectionist and use a zillion words

2:12 AM

@cairdcoinheringaahing the only problem with "banning" chatGPT is that unless people explicitly state it's GPT, there's no way to really tell if it's low-quality written by hand or low-quality automatically generated.

forest

There are ways to find out. It's being worked on now, although the "tells" are not yet public.

lyxal

The solution is to either a) increase moderation of content from new users or b) (like I suggested for AoC), raise the issue with OpenAI themselves and make it against the TOS of the AI to use it for answer posting to sites like SO

I honestly feel like the release of ChatGPT was way too fast

there wasn't waitlists like there's previously been

it should have been in a restricted beta for longer

Ginger

thanks for randomly logging me out SE

@lyxal or c) make another AI to detect ChatGPT posts :p

caird coinheringaahing

@lyxal I'll talk about this from a CGCC perspective, as SO can literally start a cult where they all worship a 26 year old half-functioning Linux laptop and I wouldn't care. But, the only problem I have with ChatGPT (or other AI written) answers on this site is the lack of credit given to the authors, that is, the AI. If y'all can create answers written by an AI for this site that are both competitive, and appropriately credited, do whatever you want, I don't care

Ginger

I have so many bad ideas now

caird coinheringaahing

2:16 AM

Go ahead, I literally just made it very clear what my personal policy is :P

lyxal

@cairdcoinheringaahing if people can get genuinely competitive answers here, there's a chance they'll want to boast about how they did it anyway, because it's so gosh dang hard to get it to do code golf properly :p

caird coinheringaahing

I can't speak for the other mods, or for SE in general, but personally, I won't delete a competitive answer that accomplishes the task as stated, just because it was written by an AI. So long as you credit the AI/the AI creators

@lyxal Oh yeah, if AI can start golfing better than us, we have bigger things to worry about than crediting them for it :P

Ginger

that's when you know you're really screwed

lyxal

so far, it's idea of "golfing" is taking a program that doesn't work and making it longer

caird coinheringaahing

At least they'll never start dreaming about golfing:

I'm just waiting for someone to write an AI that writes AIs

lyxal

Y'all are worried about AI taking over the world, when I've just discovered how fricking stupid it is

I gave it a code golf challenge and said "This is code-golf, so write a javascript solution in the fewest bytes possible (no comments, 1 letter variable names, remove whitespace where possible, etc)"

Ginger

2:23 AM

oh, we knew that already

lyxal

do you know what it gave me?

an overly long python answer

Ginger

bruh

caird coinheringaahing

@lyxal We know how stupid it is now :P

But its entire thing is self-improvement over time :P

Ginger

AI is not stupid. AI is not smart. AI is not alive. ~~AI is your friend.~~

lyxal

this fricking ai it's really starting to piss me off

it says something is "the final and most concise version of the JavaScript code for this task." when it really isn't

@graffe ChatGPT says:

> Thus, the numbers between 0 and 500 that cannot be made by sums of integers between 36 and 70 are the numbers that are not multiples of 156946307520. These numbers are 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 61, 62, 63, 64, 65, 66, 67, 68, 69, and 70.

@hyper-neutrino 72 is 36+36

graffe

@Adám well that’s wrong :)

hyper-neutrino

7:44 AM

oh I didn't think about duplicates

graffe

chatgpt is terrible at math

@hyper-neutrino duplicates are allowed but that’s interesting that you only get one more with duplicates!

hyper-neutrino

well to be fair, in most other cases if you had x+x you could also just do (x-1)+(x+1)

graffe

@hyper-neutrino true , but not all

@mousetail I wouldn’t mind if it was correct and attributed

@hyper-neutrino can the difference ever be more than one if you change 35,70,500?

@graffe APL, 34: r←⍳500⋄r⊣{500⌊r~←∪,⍺∘.+⍵}⍣≡⍨35↓⍳70 Try it online!

hyper-neutrino

@graffe yeah, what numbers between 0 and 1000000 cannot be made by sums of integers between 1 and 1

:P

graffe

@hyper-neutrino :-)

Any where the upper and lower bound are different?

@Adám wrong output

Adám

How so?

graffe

7:56 AM

37 is in the range 36 to 70 for example

Adám

Ah, will fix.

graffe

We are allowed the sum of one or zero numbers

hyper-neutrino

@graffe ~~numbers between 0 and 1000000 with sums of integers between 1 and 2~~

35: r←⍳500⋄r⊣0{500⌊r~←∪,⍺∘.+⍵}⍣≡⍨35↓⍳70 Try it online!

Actually, ∪, is just a performance improvement, and could be taken out, given enough™ time and memory.

@cairdcoinheringaahing maybe, but they'll never be good enough to write good answers on PPCG

JS experts: on a scale of 1 to 10, how cursed is this code? github.com/attempt-this-online/attempt-this-online/blob/…

It basically streams websocket messages to the UI (they are handled here: github.com/attempt-this-online/attempt-this-online/blob/…)

mousetail

Bit odd but I wouldn't call it cursed

emanresu A

After two years I'm still not sure how to use promises, but I'm pretty sure that's not it lol

mousetail

Why not put everything in the promise constructor?

That way you don't need a seperate resolve and resolve1 etc.

emanresu A

^

mousetail

why do you define newP as a function then call it immediately? There doesn't seem to be any local variables or arguments you are trying to abstract

Also you probably want to remove the event listener after the promise is resolved

Wait wait I see how it's cursed, ok I'm changing my score to 10/10

pxeger

10:18 AM

The answer to all those questions is the same: it needs to stream multiple websocket messages

mousetail

You are assinging to a function in the middle of calling it

pxeger

@mousetail Because then I'd have to reassign the event listener, which creates a race condition

The event listener needs to stay constant, but resolve and reject will change because it handles multiple promises, so I create a closure over them

mousetail

I wouldn't use promises for this, they are fundamentally single use. Trying to create a odd "chain" of them seems a abuse

pxeger

JS doesn't have any kind of stream / channel construct though

mousetail

Take a look at async generators which seem more like what you are trying to do

pxeger

10:21 AM

oh I didn't know about those

I shudder to think what Babel transpiles them to though

mousetail

A huge recursive switch/case statement

browser support is good though so you can just disable the transpilation for generators

pxeger

Actually I don't think async generators can help here, because the yield would have to be in a nested callback function

mousetail

You could try something like this:

async function abcdef(websocket) {
    return new Promise((resolve, reject)=>{
        websocket.addEventListener('message', (ev)=>{
            resolve([ev, abcdef(websocket)]);
        })
    });
}

I guess you'd need to remove the event listener which could create a race condition if a message comes in at that time

pxeger

I guess the event listener could remove itself after doing the handling

but then messages might get silently dropped

the idea of this kind of race condition being possible at all in JS kind of hurts my head

mousetail

If you do onmessage= it should atomically replace the event listenere

pxeger

10:33 AM

But messages might still be handled by the old handler

which means they never get handled, because they are passed to a resolve function that's already been used

mousetail

12:44 PM

@pxeger No they won't. Events can only fire in between other events or during a await

Neil

2:11 PM

@pxeger promsify the callback, then you can await on it and then yield the result.
