(also I'm slightly apprehensive about writing a meta post for this, probably because my last one would've won a tumbleweed badge if those still existed)
If we went through with it, we'd need to:
- (temporarily) edit the chatiquette section on off-topic stuff
- change the TST and TNB room descriptions, and pin a message in each explaining what's happening
- freeze TST

(also, TST was created against meta consensus)

lyxal

@emanresuA those are all relatively easy :p

Especially the freeze tst part

emanresu A

Yeah

lyxal

Where's your last post on it?

tag cleanup post that has +3 and no activity

Looking back at 2022 chat, I can see why we made the decisions that we made, but in hindsight the result wasn't worth it.

Meh, I think off-topic is fine when there's nothing on-topic

Q: How quickly can you type this unary string?

If I want to type the string aaa, the least keystrokes I can type it in is 3: a a a. But if I want to type the string aaaaaa, I can do it in 5: a a a ctrl-c ctrl-v, where the ctrl-c refers to copying aaa and the ctrl-v refers to pasting it. Specifically, starting with an empty "buffer" and an empty

@emanresuA that is one hell of a pfp

IIRC I copied it from a sockpuppet of lyxal's which was also called allxy (it's a long story), it's from deltarune or something

totallyhuman

oh you don't know what it is

it is indeed from deltarune

Something related to pipis?

kinda?

you'd need to be a real pipis person to see it in game

how could i possibly kill mettaton

@emanresuA how so?

I've started on drafting the introduction for a meta post calling for the experiment but discovered it's hard to word something without accidentally sounding antagonistic

@Neil that … makes sense

Simd did ask for positive integers tho

emanresu A

@lyxal I did the same, that was part of why I was apprehensive about it

(also did the same thing for calling to revert the Best Of 2023 changes and make the next one be for 2023 and 2024, and went down a rabbit hole of discovering a bunch of best of 2022's bounties weren't awarded)

@emanresuA, more of an implementation detail rather than a bug: when popping from an empty global stack, it results in pushing undefined. It might be beneficial if it pushed 0 instead; but since this isn't strictly a bug I don't mind if you opt to keep the current behavior.

emanresu A

May as well be consistent with regular popping-from-empty-input, I'll change that soon

Also noticed that you accidentally(?) pushed a file called test which contain's my hello world program, noticed it while trying to create a file with the same name for testing potential optimization to the hello world program

emanresu A

Whoops... I meant to never git add that but apparently I did

@lyxal Okay, maybe not this specifically, but general issues with the concept.

@RadvylfPrograms My downvote is there to say "I disagree that this is necessary"

Apr 21, 2022 at 4:25, by DLosc

@RadvylfPrograms Devil's advocate: what's wrong with people posting stuff here first, then having it moved? And why does the same type of off-topic content necessarily have to go into the same room, rather than a new room each time it happens?

I think this sort of “off topic “ conversation is fine because no one else is speaking rn

And a year later, a similar discussion to the one we're having now:

There's not much character in the room anymore because everyone has forgotten how to, in the words of caird, be relaxed in the relaxed room

CMC Imlement the Soundex algorithm, except the padding step

Retain the first letter of the name and drop all other occurrences of a, e, i, o, u, y, h, w.
Replace consonants with digits as follows (after the first letter):

    b, f, p, v → 1
    c, g, j, k, q, s, x, z → 2
    d, t → 3
    l → 4
    m, n → 5
    r → 6

If two or more letters with the same number are adjacent in the original name (before step 1), only retain the first letter; also two letters with the same number separated by 'h', 'w' or 'y' are coded as a single number, whereas such letters separated by a vowel are coded twice. This rule also applies to the first letter.

No

I don't think chat can do mathjax at all

Seggan

i got chatjax

there ya go

except for the equals

@mousetail ty

mousetail

You can pretty easily find a counterexample to that. a=[1,1], b=[1,2]

The sum would be 3/2 but if you sum the numerator and denominator separately you'd get 2/3

Or even just [1,1],[1,1] would give 2, 1 respectivly

@Seggan wait, did you mean smth like a/b + c/d = (a+c)/(b+d)

Behold the Folded Circle Snack Discovery

►

I have a couple of quibbles with this video:
1. Folded circle snack is *not* a good shape for keeping toppings in. Rolled-up circle snack is much better, and rolled-up circle snack with ends folded over is better still.
2. A pita is not actually a folded circle snack, it's a cut-in-half-and-hollowed-out circle snack.

@DLosc Besides tacos I don't really know many folded circle snacks. In the Netherlands we roll our circle snacks and in India we just tear and dip them them in sauce. Dosas are also rolled. I don't think they are really as universal as the video suggests

emanresu A

Calzones are sorta folded circles but they're a bit larger than what I'd call a "snack"

Even if you consider all foods I still think you'd get a minority of cultures

so i just read the meta post about chat, so does that mean off topic convos r allowed here for 3 weeks, also i noticed that tst has not been frozen yet, so has the experiment not started yet?

hyper-neutrino

it's a proposal; there'd be an official announcement if we decide on this but of course it has not been long enough for consensus

give it at least several days, possibly longer, to pick up feedback first and this is something we (the mods) and the ROs would all have to discuss so we're all on the same page

Aiden Chow

ok so it has not been decided yet?

hyper-neutrino

correct, it's only been like 6 hours

Aiden Chow

so off-topic convos here still not allowed until the proposal is approved?

hyper-neutrino

yes the status quo is still in place, nothing's changed, it's just a proposal

emanresu A

19:37

That said our moderation of what's "on-topic" here is probably going to be more lenient even before it's approved

(example: today)

Interesting. I tried the 92-byte program here and it worked.

emanresu A

Huh, it's probably weird wrapping behaviour then

Int wrapping (afaict) works but tape wrapping has undefined and very cursed results

(because the tape is built by appending a zero every iteration until length 30000, and going to the left of the tape gives -1 and points to the end of the tape, which is constantly moving)

One thing if you ever decide to change the language: Skips are extremely powerful for control flow, but also extremely annoying to use because I need to constantly update the number as I edit the code. It'd be nice if they could somehow work like gotos
