@RadvylfPrograms 1hr canvas rollback please?

Radvylf Programs

Ugh rollbacks are a pain, but sure

Unrelated String

@RadvylfPrograms Actually

in canvas, 1 min ago, by Unrelated String

yeah i think we want to give this another hour to settle down then rollback

Radvylf Programs

01:35

Okay, sounds good.

When are we thinking about ending the iteration?

emanresu A

¯\_(ツ)_/¯

Radvylf Programs

Getting some admin stuff in would be nice

emanresu A

Yep, working ont hat

Radvylf Programs

I'm adding some spicy new features to the logging in the mean time

Hopefully it won't break the timelapses

But it'll make these sorts of rollbacks a lot easier

@RadvylfPrograms Left preference, aka first operator, first action

or, if you hate yourself, implement a more comprehensive version of BIDMAS (or PEMDAS)

Radvylf Programs

No, this language allows custom operators at runtime so that would get really painful

Hey @hyper-neutrino I appear to have been booted from a specific private room?

hyper-neutrino

uh what

... how

you were a room owner of it and there's no message saying you were removed. anyway, put you back :P

caird coinheringaahing

Was I removed as an RO perhaps?

Radvylf Programs

We had that same issue with the bakery when we briefly made it private

hyper-neutrino

01:59

ah, I guess making a room private kicks existing ROs????? who tf knows how SE chat works lmao

caird coinheringaahing

private rooms are weird

I don't appear to be an RO anymore tho. Not that I especially need to be, but huh

hyper-neutrino

i just set you to write access lol - i just didn't remove you as RO when you were RO initially but i guess the system did?

caird coinheringaahing

Fair enough :P

So, for some reason, at least 5 hours after it was made private, it decided to remove me as RO and completely remove my access to the room :P

Also, the room doesn't appear to have a room owner ????

hyper-neutrino

it doesn't have to

caird coinheringaahing

I thought all rooms needed an RO?

Pretty sure if you remove all ROs from a room, the system auto-appoints someone as RO

Radvylf Programs

02:03

Only if it's active enough, right?

forest

Whoever is most active gets auto-RO. That happened to me once.

But only if there are no other ROs and the room is not active except for you for some time.

hyper-neutrino

then i guess i will appoint myself

Radvylf Programs

Or should we hold an election? :p

We might need a room to discuss whether not to add an RO to the room about adding ROs to rooms

caird coinheringaahing

I nominate Dennis, I trust him with any and all moderation powers, but the chance he'll use them is slim enough for it to not matter

Also, while the trend of users leaving suggests otherwise, I do still hold out hope that Dennis returns. Not only would I like to see probably the most influential user in our history come back, but his return would almost definitely indicate an improvement in his health, which I'd love to see

Oh wow I'm 8 suggested edit reviews away from a silver badge

caird coinheringaahing

@RadvylfPrograms Nice, only the 7th person on the site to get that one :D

Radvylf Programs

GRT for the win :p

caird coinheringaahing

GRT for the win indeed :P

I find it crazy that WW has a Steward badge (1000 reviews) in Close Votes, while I'm 4th of all time, and I only have 370

Speaking of silver moderation badges - I find it funny how I have deputy on SO and MSE yet not here

@RadvylfPrograms I never knew you had an inbox interrupt userscript

the amount of times I've needed one is uncanny

although I just realised the userscript won't help me out on mobile because DDG don't userscripts

oh well

also @RadvylfPrograms does GRT make a noise on review items?

Radvylf Programs

Yes

lyxal

is it customisable?

Radvylf Programs

It can be toggled though

@lyxal Yes, you can change the URL in the source code :p

can't wait to confuse myself by using the same noise Smokey uses lol

@UnrelatedString @hyper-neutrino Out of interest, have either of you taken a look at Legacy's Allure (like, gameplay, cards,etc.)?

Unrelated String

i've lurked more in the discord but been too busy to really look at any of the resources

i say while spending like 20 minutes at a time on canvas lmao

hyper-neutrino

i forgot about the game and that i joined the discord

i am not busy i just have the memory of a goldfish

caird coinheringaahing

02:53

@UnrelatedString Fair enough :P Can be difficult to get involved if you haven't actually played a game, it's fairly complex to begin with

@hyper-neutrino Goddammit :P

On the one hand: I hate doing surveys
On the other hand: if this is implemented properly, and rolled out network wide, we could benefit from this

lyxal

dear gosh they've made a gaming version of The Key

Q: Is Wally there?

Inpired by recent Stand-up Maths' video. Task Wrapping a list x can be seen as inserting "line-breaks" into x every n-th element, or forming a matrix from x with n columns (feeding rows first). To be perfectly rigorous in the definition of x wrapped into a matrix, we can pad the last row with 0s....

@AidenChow Well, most people I've talked to have said the same thing, so maybe the average has been dragged down enough that like a 70 would be a 4 or 5

I'm dreading going to school today. Not because of AP Seminar, but because I know I'm walking into a building with unusable WiFi.

Well, gotta go anyway, so see y'all there (but won't be able to alert you of that fact unless I click "retry" a half dozen times) o/

Does anyone know why so many new contributors have submitted their first posts to King of the Holster? Did it pop up on HNQ? Was it the bounty?

Ginger

Okay, so

I think that sechat is pretty much done

are there any extra features y'all'd want in it?

Radvylf Programs

13:26

@Romanp Almost every moderately good question here becomes an HNQ, so yours definitely did. And it has a somewhat catchy title, and KotHs are (IMO) the most fun challenge type here, so it's the perfect challenge for new users.

Romanp

Makes sense

Ginger

@RadvylfPrograms You run a bot, what features would you want in a next-gen bot library?

Radvylf Programs

Reliability

Ginger

ooh, good one

Radvylf Programs

NP/SP started out its life by going down every couple of days whenever anything moderately unexpected occured

Ginger

13:29

well, currently if sechat detects an error in a handler it just logs it without crashing

the old bot library also had issues with correctly halting all threads when the program shut down, sechat fixes that

Radvylf Programs

Any library intended for bots needs to be tested with fire. Pipe /dev/random into whatever internet library it uses. Disconnect the WiFi halfway through. MitM the connection with a self-signed (and invalid) certificate. etc.

Ginger

jesus

well, I haven't done any of that yet

Radvylf Programs

I've had all sorts of "oh that'd never happen to me" stuff happen with NP/SP, and you should expect it

Ginger

lemme go do that

Radvylf Programs

And be mindful of when you should crash instead of logging an error. If something's in an unexpected state, it might be spamming RO-only operations or pushing its anti-spam-cooldown into the double digits.

Ginger

13:31

hmmmmm

well, I can make it so that errors in any request methods can be logged instead of crashing

Radvylf Programs

Things like systemd will handle auto-restarting, so whenever the library's not sure if what's going on it correct, going down for a second might not be the worst idea

Ginger

right

Radvylf Programs

Whereas for routine network errors like the internet going down or random garbage being piped in or an MitM should be handled (probably without any logging at all) without any crashing

Ginger

Well, I've added a try block to the request function

I guess I can just make it log that as a warning?

Radvylf Programs

Make sure it doesn't log stuff every time it receives some sort of invalid thing, or you'll fill up stuff with a gigabyte of logs.

Maybe a debug option in the constructor (if you're going OOP)

Ginger

13:35

Exceptions generated by the request function get logged

I'll add an option to shut that off

Radvylf Programs

Maybe make it log any unique errors once, for debugging, but then never again.

Ginger

hmm

Radvylf Programs

Or perhaps every time it's a power-of-ten number of times that error's occured, print that, so you can tell the scale of an issue

Ginger

Currently, if an error occurs during websocket connection it just raises an error

I think that's a reasonable "oh shit restart" scenario

Radvylf Programs

Well, keep in mind the websockets decay away after some time, so restarting them should be a normal part of the library's functionality

Ginger

13:37

they do?

I... did not know that

Radvylf Programs

Yep. All sorts of stuff can cause them to close.

Ginger

okay, good to know

Radvylf Programs

I'd retry about ten times with delays increasing from ~100ms to ~10s before panicking

And if you fail to receive a "ping message" on a chat websocket for more than a minute, restart it whether it's open or not

Ginger

okay

more handlers added

Radvylf Programs

I'd leave it running for a week or two before publishing too, to catch any other issues

Ginger

13:45

It's not bulletproof, not by a long shot, but I'm going to run GingerBot as a test for like a week to iron out the bugs

ninja'd

Resiliency aside, any other features?

Radvylf Programs

Can it read the transcript?

Ginger

no

I can add that tho

Radvylf Programs

I'd add that. How does it handle getting cooldown'd?

lyxal

are we talking about the KoTH runner or the chat client?

Ginger

Chat client

@RadvylfPrograms Wait 3 seconds and try again

Radvylf Programs

13:48

I'd make the amount of time it waits increase

Ginger

hmmmmmm

Radvylf Programs

If you always wait 3s, it'll stack and you'll be in the double digits soon

Ginger

okay

done

lyxal

wait is this a SE chatbot framework or a chat relay of some sort?

Ginger

framework

lyxal

13:52

can I star or pin stuff with your client?
