hi all

I wish this channel were 5 times busier

Unrelated String

don't we all

graffe

maybe not the shy ones amongst us :)

I have tried using discord but it is too confusing

@UnrelatedString do you understand discord? I would love an explanation

Unrelated String

what's confusing you

graffe

so... say I want to go back to the channel #deel-rl-general ? I receive an email from discord that says "view messages" with a link

Unrelated String

wh

what

graffe

12:31

if I click on the link it takes me to a page that says "Welcome back" and asks me to log in with a QR code

I just want to go back to a channel I was in before!

Unrelated String

either you're repeatedly logging out or getting spam emails

graffe

the email has the title "You missed messages in RL Group"

I never deliberately log out but I do reboot my computer sometimes

RL == reinforcement learning I should say

Unrelated String

the qr login feature was a pretty popular attack vector when it was new and afaik it should always give you the option to log in with normal username-password on the same screen

lyxal

@graffe gist.github.com/Lyxal/6b27a0d61ed98b0f3ff0171bf4fba62e

graffe

@UnrelatedString it does but that doesn't go anything when I click Login

Unrelated String

12:33

wack

assuming this is browser discord i guess just try installing the desktop application and see if that does any better

graffe

@lyxal wow.. does it tell you who wrote the code?

@UnrelatedString I am on windows on chrome

could that me the problem>

?

Unrelated String

probably not? but browser discord does seem generally weirder than the standalone

lyxal

@graffe gist.github.com/Lyxal/3cebf6d10b18091d31f1c21e5b0e7fe6

@graffe no, it doesn't tell me

graffe

@lyxal my goodness

could you try C++ and Python now please :)

this is so much fun

lyxal

note that it very probably doesn't actually do what you want

graffe

12:36

why do you say that?

lyxal

Because I don't actually know what either of those scripts should actually do

graffe

ok

lyxal

so I have no way of verifying if its correct

graffe

it does seem a fun way to inject malign code

if you can get copilot to recommend it

lyxal

here's an example of copilot getting it horribly wrong

it starts strong with comments describing the problem but then imports the entirety of itertools one import at a time

twice

pxeger

12:39

and operator lol

graffe

@lyxal that's fun :)

can you report that sort of thing as a tester?

lyxal

I've never actually looked into places where I can report stupid things like that

graffe

what do you get for C++?

it's like you are testing a driverless Tesla :)

lyxal

one moment

graffe

...

lyxal

12:43

gist.github.com/Lyxal/a48a0682e94f860fa30c63501bf0d26c

it once again starts strong

it opens with the GNU licence

followed by some neat little functions and constants

graffe

interesting

these are good examples for a bug report!

lyxal

but then it devolves into a, b, c...aa, bb ...

interestingly it stopped after int jjj

graffe

do you have a quick way to make gists?

lyxal

I just click the new gist button

graffe

I always use bpaste

where is this button?

lyxal

12:45

gist.github.com

it's the plus button

pxeger

I really like the gh gist create command from GitHub's official CLI

graffe

thanks

lyxal

some other things I've used it for include python to java, a befunge "interpreter" and a brainfrick "interpreter"

graffe

the python to java is really cool

can you ask it to optimize code too?

lyxal

that could be a bit much for it

graffe

12:47

:)

lyxal

it can't code golf

yet alone optimise

graffe

can it do Julia and R too?

if it can't golf it is not worth it!

user

I don’t understand why the github gists website is sort of separate. If you want to make a new repo from there, you need to go to the github.com/* and the button to make a bew repo is only available there

pxeger

GitHub Gist has always given off the same vibes as SE chat to me

a separate project from the main site, probably developed by a random intern or something, and kinda shoddily integrated into the main site

lyxal

@graffe it's worth it if you use it as an assistance tool for the completion of lines of code that would otherwise be "tedious" to write

user

12:49

@lyxal whoa, python to java is pretty neat, it “understands” what the range does

@pxeger hmm, possibly, although not as shoddy as chat

graffe

@lyxal it seems pretty amazing

who makes it?

lyxal

Github

user

They did have the url shortener they had to drop

lyxal

they use the Codex AI-completion model developed by OpenAI

and that's part of the GPT-3 suite

which just happens to be owned by Microsoft

so in reality, copilot is microsoft

pxeger

@lyxal the existence of class Getch reminds me of some other code

graffe

12:51

interesting

user

Tangentially related but Can i get an f for atom in the chat

pxeger

I'm sure it's just copied that from somewhere

graffe

they do have some very smart people on microsoft

lyxal

@user ikr. No copilot for atom

pxeger

@user ah, found it lol. code.activestate.com/recipes/134892

user

12:52

@graffe github was acquired by microsoft

graffe

@user ah yes

I forgot about that

I should start talking about acquiring things

I acquired a pint of beer last night...

user

The stuff github does isn’t necessarily microsoft stuff

@pxeger what code is that?

lyxal

@user copilot is in a sort of interconnected way

not that there's anything wrong with that

graffe

@lyxal do you know the full list of languages it covers?

lyxal

no

graffe

12:54

can you try assembly, R, Julia?

I mean just for fun

lyxal

the idea is that it should be able to pick up the semantics of any language

graffe

that seems hard

lyxal

it was (iirc) trained on github repos

pxeger

It does have a limited list of languages though, I'm sure

lyxal

> GitHub Copilot works with a broad set of frameworks and languages. The technical preview does especially well for Python, JavaScript, TypeScript, Ruby, Java, and Go, but it understands dozens of languages and can help you find your way around almost anything.

From their website

graffe

12:56

I really want to know if it can do assembly

interesting

lyxal

How to write comment in assembly

because it needs a prompt before it can do anything

pxeger

@lyxal ; comment

graffe

en.wikibooks.org/wiki/X86_Assembly/…. ?

snap :)

lyxal

it don't like assembly

graffe

:(

c++?

lyxal

12:58

I already linked a C++ example

graffe

oh sorry

let me see

lyxal

pxeger

apparently this person is an author of an LZO compression library

graffe

14:01

@lyxal thanks

What is the largest bounty these days? Is it 500 points?

If you put such a bounty on a question does that mean it can never have another bounty?

ophact

you can continue

graffe

But with the same bounty again?

ophact

you can keep putting 500 rep bounties

theoretically you can put 50k rep on a single answer

or if you're Jon Skeet or one of the three other millionaires on SO... one million rep

by offering two thousand bounties

graffe

By doing 500 repeatedly?

ophact

yep

graffe

14:05

Cool

I have asked a question on stackoverflow and I suspect I will never get an answer

But I have quite a lot of rep to give away

CMQ If I start at the origin and walk one unit distance in a random direction, what is the probability distribution for my new y value?

pxeger

is the random direction chosen uniformly in [0,360)?

graffe

Yes

m90

@graffe I think it's (1-y²)^-½ / π.

ophact

what the what? How did you get that.

pxeger

The y value is given by sin(θ)

and θ is a uniform random variable

ophact

14:18

Ah, I see

m90

Yup.
Then y<=A if sin(theta)<=A
prob(y<=A) proportional to arcsin(A) + pi/2
differentiate

pxeger

So we just want the pdf of the transformation sin(θ) where θ is a uniform crv

or cdf

yeah

ophact

Well now we are talking about PDFs it looks like...

graffe

@m90 ooh .. Thanks!

Yes it is the pdf I am looking for

Ginger

wait, did the big PFPs on the user pages get rounded corners?

also it's NP's cake day!

Q: Draw New Posts' Profile!

New Posts and New Sandbox Posts are chatbots that occupy CGSE's main chatroom, The Nineteenth Byte. They've been doing their jobs for almost one full year now, so I thought I'd make a challenge to honor their contributions! The challenge is simple: Draw the profile picture of either New Posts or ...

caird coinheringaahing

@Neil The profit happens at the same time as posting, clearly, so I numbered them the same :P

pxeger

@NewPosts @Ginger You didn't address all of the sandbox feedback. The images you linked are not pixel perfect they're 48x48 but the original pixel art was 20x20 AFAICT. Presumably, the output should be the pixel perfect version? If it's a bitmap, does it have to be at a resolution which is an exact multiple of 20x20?

Ginger

15:14

whoops

The 48x48 ones are what should be output

pxeger

@Ginger including the blurriness / anti-aliasing? That's stupid.

Ginger

I fixed the anti-aliasing

those images are dual-color

pxeger

huh, Firefox' zoom is just bad then

Ginger

can confirm

Jo King

16:37

annoying fact: the keycode for the mute button on chromium is the same as the key for - on firefox, so youtube will trigger the "make the subtitles smaller" shortcut whenever you mute it with a physical button

apparently managing some of these keycodes are a nightmare across different browsers

Ginger

@JoKing relevant xkcd

hyper-neutrino

i am proud to say that i correctly guessed which xkcd that was

Jo King

16:52

me too

problem is that there is no standard, every browser just does what it wants

> An event module designed for use with keyboard input devices will be included in a later version of the DOM specification.

"eh, someone else will figure it out"

pxeger

17:10

@hyper-neutrino that's one of the ones whose number I know by heart

des54321

18:26

ugh why doesnt python let you do from module import foo,bar as A,B

you have to do from module import foo as A,bar as B

Bgil Midol

I prefer from module import foo as A,bar as B over from module import foo,bar as A,B

Q: Using compression tools

Are you allowed to use compression tools (e.g. gzip, xz) in your code? For example, a shell script with: cat script.sh.gz|gzcat|sh (25 bytes) where the content of script.sh.gz is: ãö}mbhello.sh=é¡¬0CÔ˚ s⁄m¡ Ó¸@YÕZ‘6Sõ2Ò˜¥∞!ÂŸŒs8;¡Ö!6…¡ûvÂÊ|AeQ¨Yñl‚tòÑ∑4=†Œ(ºˆuñ∏fñBªÁŒUëdkÑ»+,iT8Û"Ù€õﬂ0w©ˇ"...

discussion code-golf

ophact

18:41

I love how there are no related questions to that one

as if the system couldn't decipher the question

oh wait now there are

Radvylf Programs

Idea: Instead of security questions and stuff, in the future, you talk to an AI for a few minutes, and it learns your personality and writing style. Then, if you forget your password, you just have a brief conversation and it decides if you seem like the same person.

oops my personality changed

CMQ (off-topic): Good 2D JavaScript game engines?

pxeger

Do you really want a whole game engine?

Ginger

yes

Q: Collatz Encoding

@RadvylfPrograms Do we really have good enough AI for that right now?

I don't think so, which is why I added "in the future" :p

A: Sandbox for Proposed Challenges

Draw the Support Ukraine Flag A sequel to this challenge. Recently, I learned that there is a flag symbolizing opposition to the war in Ukraine. My first flag-drawing challenge went well, so here's a sequel. The Challenge The flag: The flag is divided horizontally across the middle into three e...

Ginger

I did it again

this will, to be honest, probably not go over as well

I think that I may be too blatantly capitalizing on the war

only time will tell...

Radvylf Programs

@Ginger That and it's just a bad challenge in general (the first one too really, but I don't think people really wanted to VTC a challenge that was supporting Ukraine)

This is the graphic output equivalent of "print Hello, World! but backwards"

caird coinheringaahing

@SandboxPosts I'd VTC this as a dupe of the Ukraine Flag one

Honestly, I was shocked that we didn't already have a "flag with horizontal bars" challenge before the Ukraine one. I was close to VTCing as a dupe of the French flag, but wasn't happy enough to use my hammer

@des54321 That violates the Zen of Python:

> Explicit is better than implicit

Radvylf Programs

23:25

How's it any more explicit to do a as x, y as z instead of a, y as x, z?

I think the issue's more that it creates an ambiguity. Is it a, y as x, and z, or is it a as x and y as z

caird coinheringaahing

x as a, y as b is much more explicit as to what a and b are

Radvylf Programs

I mean, I don't see why. By that logic a, b = c, d shouldn't work

Since a = c, b = d would be much more explicit

caird coinheringaahing

I suppose

Wezl 'l o - o l'

@Ginger jquery

Ginger

well, we all make mistakes

sorry yall

Radvylf Programs

23:31

?

Wezl 'l o - o l'

@Ginger to be clear this is not targeted at me?

Radvylf Programs

For what

Ginger

@Wezl'lo-ol' no, of course not

I was referring to the challenge

Wezl 'l o - o l'

also hi tnb

Radvylf Programs

@Ginger Oh, dw. You didn't do anything wrong, it's just a rather boring and dupe-y idea for a challenge.

Ginger

23:32

welcome back wezl!

Radvylf Programs

It happens to everyone, and it doesn't cause any harm to anyone

Ginger

so, I've come to propose another stupid(?) idea

Wezl 'l o - o l'

it took me a month to realize that people were still here

Ginger

@RadvylfPrograms remember how we were discussing KOTH arenas?

Wezl 'l o - o l'

why don't we all move to campfire.gingerindustries.repl.co ?:<

Ginger

23:33

been a while since I've seen that link

but anyway

I'm too lazy to make a whole website for that idea

so, here's another way to implement it: GingerBot

no, I'm not kidding

GB would check for questions for it to run (maybe with a custom tag? IDK), get their KOTH code... somehow, as well as any responses, and run them through RTO and edit the original post with the results

Radvylf Programs

Why does that have anything to do with GingerBot though

Ginger

you need an account to edit posts, GB is the first one that came to mind

Radvylf Programs

It could just as easily be any backend script, no account is required lol

@Ginger oh true

Ginger

this is just an idea

but I think it could work

Radvylf Programs

Auto-editing leaderboards into the question isn't something I'd want to add

Ginger

23:38

maybe

Radvylf Programs

Since we discourage leaderboards anyway, and it adds unnecessary bumps, and bots on CGCC isn't really something we should encourage

Ginger

then where would you get the results?

Radvylf Programs

rto.run/koth or something

Ginger

good idea

Radvylf Programs

You'd just have a permalink, which you'd put in the question body

Ginger

23:39

that sounds spicy to me

Radvylf Programs

And that page would have the controller UI, leaderboards, and an editor for adding and testing new bots

Ginger

less spicy

I am tired of making websites

if you want to go ahead

I will just make the "bot"

Radvylf Programs

I don't want to discourage you if you want to make a mockup or something, but I prefer to work alone on this sort of thing

Ginger

you do frontend and I do backend

now, let'sa go

Radvylf Programs

@Ginger Like I said, feel free to make a mockup, but I don't like the idea of allowing someone to do a ton of work on something when it's pretty likely I won't use their work

Ginger

23:44

>:(

Radvylf Programs

And it is rather unlikely I would use your back-end, as I'm constantly changing what I want RTO to do, and having to learn someone else's code just makes that more complicated

Ginger

I want to do this

RTO has hosted other people's projects before, could you do the same for me?

Radvylf Programs

If it's a personal project, sure. I just don't want to mislead you into thinking it's going to be an official part of RTO, since I change my mind about RTO way too often to be able to promise that.

Ginger

of course

this would be a personal project

Radvylf Programs

But RTO's server and domain is available any time for anyone who wants to host a project of theirs, as long as it doesn't use an unreasonable amount of computational power/bandwidth

Ginger

23:47

nice

now, what should I call this system?

I need a punny, KOTH-related name

anyone?

@RadvylfPrograms can I use koth.rto.run for this?

Radvylf Programs

I'm going to say no for now, since I might use that for the official RTO KotH tools.

Ginger

hMmMmM

Radvylf Programs

?

Ginger

how about gkoth.rto.run?

Radvylf Programs

Sure, was actually going to suggest that

Ginger

23:55

nice

Radvylf Programs

Or goth.rto.run lol

Ginger

seeing that gave me an instant mental image of my profile with a goth haircut and oh my god it's the funniest thing I've thought of in a while

Radvylf Programs

Although goth.rto.run is also reserved in case I become an emo, sorry

Unrelated String

lmao

Ginger

will you change your pfp to solid black?

Radvylf Programs

23:58

I actually do have a black pawprint saved for after the ukraine one lol
