@cairdcoinheringaahing I believe it's my fourth-most-used language (behind Pip, QBasic, and Python).

caird coinheringaahing

@mathcat There was a time when this actually was happening - it got so bad that I believe some staff members received death threats

user

o.O why would anyone do that? (and did they figure out who was behind it?)

caird coinheringaahing

@user I have no idea, and I have no idea

I believe this was round the time that staff withdraw a lot from meta, and Monica got fired, so Autumn 2019

See meta.stackoverflow.com/a/387633/7742131 for example

Also @taRadvylfsriksushilani I managed to do something in ultrarisky

ta Radvylf srik su shilani

Nice!

I wrote an addition program in In Floop that can handle unused inputs

r+s[r-]r[-s+n?o?]r+n[r-n-o+]r[o;]

Time to try multiplication

emanresu A

I was trying to do that

ta Radvylf srik su shilani

This is gonna be harder than I thought

emanresu A

Also dso.surge.sh/#in-floop

ta Radvylf srik su shilani

I've managed to get rid of s without any additional byte count cost by using the array

I think n, o, and s should be all that's required for multiplication

emanresu A

8:57 PM

It's pretty much repeated addition

ta Radvylf srik su shilani

yeah

I'll actually need to use s to keep track of the current state I think

emanresu A

You can always just use s as the tape pointer if you need more

The problem is there's no easy way to clone variables

pxeger

LYaL soon, what is it?

emanresu A

So our current methods of addition don't work very easily

pxeger

looks like it's Scala

Hey guys!!

emanresu A

@user Lyal is scala

ta Radvylf srik su shilani

@AviFS Hi!

caird coinheringaahing

@AviFS Hey :D

ta Radvylf srik su shilani

Oh, quick question about OISB: If the user submits invalid inputjson, should it be ignored, or should the connection be closed?

Ginger Industries

@AviFS o/

ta Radvylf srik su shilani

9:02 PM

(I'd ask this in the discord but it's blocked in school lol)

AviFS

Looks like Haskell and Scala are tied for LYAL

Who's gonna break the tie!

pxeger

Scala was posted first

so it's Scala

Ginger Industries

someday, I will get APOL to be in LYAL

Aaroneous Miller

aw, I was gonna vote for Scala, but it turns out I already did

pxeger

unless the votes change I guess, but we haven't really decided when they should be considered frozen

AviFS

9:05 PM

@taRadvylfsriksushilani @cairdcoinheringaahing Hey Red! Hey Caird! Hi hi!

emanresu A

@taRadvylfsriksushilani If someone tries to ACE you ban their IP adress

AviFS

@GingerIndustries I see you're account's just 2 months old, which would mean we haven't met yet. Unless you're someone in disguise... Hi, hello, welcome!

caird coinheringaahing

The nominations for LYAL aren't fully decided by votes and times - the votes are indicators of langs people would like to be LYAL, and we decide around the time what lang it should be

AviFS

9:07 PM

Hey DLosc!!

Ginger Industries

@AviFS that is correct. I am a relative newcomer to TNB

ta Radvylf srik su shilani

@emanresuA Well, invalid input is overwhelmingly more likely to be me making a mistake while debugging, or someone making a mistake with the API

emanresu A

True

Wezl - y izl

Hi avifs. are you a file system :P

AviFS

@GingerIndustries Well hello there, relative newcomer.

Ginger Industries

9:07 PM

@Wezl-yizl good question.

@taRadvylfsriksushilani what does the name OISB stand for?

Oxygen-Included Seedy Bread

@taRadvylfsriksushilani Hm, cool

ta Radvylf srik su shilani

I think I've got multiplication almost working if nothing goes horribly wrong

AviFS

@Wezl-yizl That's some neat ambiguity. I meant the second one. But the first isn't terrible, either!

Wezl - y izl

@AviFS maybe file systems that are avid about greeting people :P

emanresu A

@taRadvylfsriksushilani That's r+<condition>[r-<if>]r[r-<else>] right?

AviFS

9:10 PM

Reminds me of a (Phillip Wadler = Haskell guy) talk name.

ta Radvylf srik su shilani

@emanresuA Roughly, yeah

You can save a byte: r[r- -> r[-

AviFS

(Programming Languages) in Agda = Programming (Languages in Agda)

emanresu A

Yeah

AviFS

That was actually the name of the whole talk, haha

ta Radvylf srik su shilani

Since in both blocks you know what r is and what it should return, you can do whatever you want with it as long as you set it back to the right thing at the end

AviFS

9:11 PM

@Wezl-yizl I'm biased, but I approve this message.

caird coinheringaahing

Oh no, we're going to have 4 pinned messages for LYAL

Ginger Industries

@cairdcoinheringaahing good thing we've got all these spare thumbtacks

caird coinheringaahing

I think it's ok to unpin the sock one later, seems like it's gotten through to people

ta Radvylf srik su shilani

I don't think we need the Proof Assistants one anymore

Yeah

@Wezl-yizl I, for one, am both ^_^

Ginger Industries

I'm a phileaphile: someone who enjoys learning about things to learn about

DLosc

I think the "phil-" root has to do with enjoyment, not with learning

caird coinheringaahing

Hmm, I'm still getting used to "Score" instead of "Votes" in the sorting thing - it still feels slightly too new :P

Ginger Industries

@DLosc ¯\_(ಠ_ಠ)_/¯

caird coinheringaahing

@cairdcoinheringaahing I don't like sevens. They're coarse, and rough, and irritating, and they get everywhere.

ta Radvylf srik su shilani

@taRadvylfsriksushilani ^ should do this after SE Nitro

ta Radvylf srik su shilani

Okay, let's try this again. Had a bug that made the condition negative for something.

Okay, forgot to decrement a counter. Let's try again again.

Looking good so far, n got decremented to 0 successfully

Okay, and now o's been decremented and n's been incremented back to the original. Looking good so far still!

Wait, nope

Config went negative again

user

@emanresuA \o/

Are we doing Scala or Haskell then?

ta Radvylf srik su shilani

Okay, looking good so far but it just keeps adding instead of stopping lol

emanresu A

I was trying yesterday night, then discovered two bugs

(And later patched those)

ta Radvylf srik su shilani

Okay...found the bug, I think it should work now

Wish me luck again

@taRadvylfsriksushilani You gonna answer with that?

Yep, was trying to find the question

Why nors for the variables? Is it because they look nice, or do they mean something?

I still think RIO is the obvious choice: Run It Online

emanresu A

rio.surge.sh is taken though

So is rio.run

Adám

Why surge.sh?

@emanresuA Ah yes.

emanresu A

@Adám Cause I'm poor and can't be bothered getting an actual domain

Adám

yco.run: Your Code Online - Run

aco.run: Any Code Online - Run

Wezl - y izl

11:05 PM

@Wezl-yizl scala's similar: (a,b)=>(0to a).sum+b (20 bytes). I'm not sure whether type signatures need to be included

ta Radvylf srik su shilani

ryc.run: Run Your Code

rtc.run: Run This/That Code

Wezl - y izl

also I'm not sure how to translate the second solution

Adám

But then you don't want .run

ta Radvylf srik su shilani

RTO has .run

I don't see why "Run" can't be in both the title and the TLD

Adám

RTO (Run This Online) is way better, imo, than ATO (Attempt This Online)

emanresu A

11:07 PM

^

ta Radvylf srik su shilani

The funny thing is that pxeger came up with both

I like ATO though, it's a good name

Adám

But when I post something serious (on SO etc.) I wouldn't want to include an "Attempt this online!" link. That sounds silly, as if it might not work.

eto.run exists, and is better: Eval/Exec This Online.

ta Radvylf srik su shilani

That's true, but I thought people still just wrote "Try It Online" when linking to ATO/RTO/DSO/...

emanresu A

I don't have a server, don't want to buy one, and don't trust myself to make an actually secure sandbox

ta Radvylf srik su shilani

It is a good idea to have a place where JS-based interpreters can be run, since it'd have more performance and flexibility than the more traditional model.

Adám

11:15 PM

Agreed.

@emanresuA Should be able to add ngn-apl and BQN too, then.

emanresu A

Adám

And I think J can now be compiled using emscripten.

Aaroneous Miller

@Adám eso.run (Eval Stuff Online) would be perfect, but unfortunately it’s already registered

ta Radvylf srik su shilani

It's theoretically possible to write programs in In Floop that add or multiply signed integers, since it can handle them perfectly fine, but I don't want to even attempt that lol

How about Do Stuff Online?

@Wezl-yizl (0.to(_).sum+_ should also work (DLosc came up with it earlier))

On the one hand, it's good for golfing. On the other hand, there's no need to have it in practical code

DLosc

11:32 PM

@user Not on Scastie, apparently.

Aaroneous Miller

Using 1 and -1 instead of 1 and 0 in the data string for a BCT program wouldn’t affect the TC-ness, correct? I feel like it is extremely obvious that it wouldn’t, but I just want to confirm

DLosc

@AaroneousMiller As long as -1 in your variant behaves exactly like 0 in standard BCT, then no. It's the same thing just written differently.

ta Radvylf srik su shilani

Yeah, you can trivially convert between the two

Aaroneous Miller

Cool, just making sure

I’m gonna try something really painful and i dont know if I’ll be successful
