@hyper-neutrino Ok, so you have 83 "well-received" challenges. One predates the latest SEDE update, and my query returns 82 challenges

Counting by hand, I found 8 days where you posted 2 challenges, so you should be 74% of the way. Have you reloaded your user page?

@cairdcoinheringaahing Have you had any problems with GRT recently?

I don't remember if the last one was yesterday or today in your timezone

caird coinheringaahing

@RedwolfPrograms When I got back from work I had about 10 tabs open with "pending" review tasks

But no "new" problems

hyper-neutrino

@cairdcoinheringaahing i've reloaded a couple of times and it was on 71 two days ago so there's no way it could be higher than 72 (with my computer thief challenge)

Redwolf Programs

@cairdcoinheringaahing If you want, you can change the number at the end of line 100 (currently 2500) to something a lot bigger like 10_000 or 20_000, that might help with the issue since I'm still not sure where the issue is

DLosc

Okay PHP what o.0

Redwolf Programs

I believe it has something to do with the browser not running the function to update the last time it saw a page while other things are loading

caird coinheringaahing

00:33

@RedwolfPrograms Interesting. That number is on line 98 for me

Redwolf Programs

Oh, I think I have extra debugging stuff.

caird coinheringaahing

@RedwolfPrograms Knocked it up to 25000

Redwolf Programs

Okay. The only effect of making that number larger is that there's a chance it could miss a review if it's right after a different one, but as long as it's less than 40000 it should actually be fine I think

Redwolf Programs

A username

Yes feedback

Redwolf Programs

Oh just noticed that

hyper-neutrino

it is probably necessary to clarify what "different languages" are (this is always important in polyglots)

Redwolf Programs

^

hyper-neutrino

04:52

for example, python 2 vs python 3 - can I use both for 2 languages?

and then, python 3.7- vs python 3.8+, for example, since a lot changes there I believe

A username

True - What do you think?

lyxal

and what about vyxal 2.0.0/2.0.0a/2.1.0/2.2.0 etc

A username

Again, do you guys think I should allow that?

Redwolf Programs

Seems fine

hyper-neutrino

i think it makes sense to allow different versions

since each needs to output a unique number

A username

04:54

Ok. That's the consensus anyway

Redwolf Programs

Looks like a good challenge

hyper-neutrino

it'll be challenging enough to use two versions of a language, especially very minor changes like 2.0.0 vs 2.0.0a (i think that's minor, if not then lyxal ur version numbering sucks)

lyxal

it looks like there may have been 100 commits between 2.0.0 and 2.0.0a

roughly 100 commits

hyper-neutrino

i mean if all 100 commits were bug fixes on the same thing bc bad then that's still a minor change

lyxal

> Because a lot of bugs have been fixed since the first v2.0.0

hyper-neutrino

04:57

but if 1 commit rewrites the entire project then that's a major change

A username

Ok, posting now...

lyxal

> some commands that weren't implemented are now implemented properly

hyper-neutrino

lol

Bubbler

I've seen something like "using the version number directly provided by the language implementation is disallowed", though it could be argued to be a non-observable requirement

hyper-neutrino

I think the polyglot-chaining challenge mentioned that though there are too many numbers now for that to probably actually matter

for this challenge i doubt it'd be a problem even if someone can leverage that

Unrelated String

05:33

> Hey, do you know the Māori word for 4?
Whā?

A username

Yes

Razetime

@DLosc yeah requires mutation for efficiency

I want to achieve maximum optimization with what pip has got

hyper-neutrino

05:47

including . anywhere in a vyxal program seems to just make the whole thing decide to do nothing

the lack of error messages is rather annoying for trying to figure out what actually goes wrong when a program doesn't do what it's supposed to

which is like half the time I try using this language

this prevents me from polyglotting with brainfuck entirely

Razetime

@hyper-neutrino the keyboard says "decimal separator"

hyper-neutrino

huh

right forgot about that

does not specifying digits around it just error?

Razetime

seems like it

hyper-neutrino

jelly automatically puts a 0 to the left if empty and 5 to the right if empty

still, no error messages

Razetime

i think the silent errors are probably inspired from 05AB1E

hyper-neutrino

05:50

make a flag for it

:P

Razetime

Stax also does this but halt program execution and open step through debugger command go brrr

Unrelated String

@hyper-neutrino the weirdest thing is some errors make it print 0 and give you a python error message but others that are seemingly related are silent

hyper-neutrino

yeah lol

brain-flak and jelly aren't easily compatible because jelly doesn't seem to like round brackets (especially opening) and I can't put it in a string because python won't accept the non-ascii characters

oh also vyxal just freezes and runs into an infinite loop i think when i use jelly quotes

Razetime

@UnrelatedString I assume the silent errors are "Expected" while the python errors are probably unexpected and the stack is emptied and hence 0 is printed

hyper-neutrino

never mind it runs. maybe all the brackets slow it down or something

Unrelated String

05:57

( in jelly is one of those undefined characters that separates and discards chains right

hyper-neutrino

not sure, lol

Razetime

@hyper-neutrino err, what brackets are you using

hyper-neutrino

()

Razetime

oh that's repeat n times in vyxal

hyper-neutrino

it shouldn't be getting run lol

1or"9,Q"
print(1/2and 5or 3)
1or"“(()()()()()()()()()()())”"
7

doesn't matter because this won't work anyway, but that is what i had

Unrelated String

05:58

coincidentally that helps a lot with what i am trying to do right now

Razetime

uh wow

Unrelated String

i completely forgot the whole

keg control flow thing

Razetime

ah yeah pipe in between

hyper-neutrino

why does this take so long

i have this now

1or"9,Q"
print(1/2and 5or 3)
1or"((1)(1)(1)(1)(1)(1)(1)(1)(1)(1)(1))"
7

also when a program is taking a long time to run it seems to cause any instance of the pythonanywhere page to slow down / freeze

i can't load a new vyxal window while my program is stalling

Razetime

06:16

@hyper-neutrino this must be fun

hyper-neutrino

technically an ill-meaning individual could just lock the online interpreter for everyone assuming that's how it works, right?

though idk if it affects other people. maybe just my computer/network, not sure

A username

I mean, there's tsh's 10-flavors-of-JS program...

But AS is deprecated so it's pretty much untestable...

lyxal

06:44

@hyper-neutrino probably due to having to parse the entire brackets

Razetime

vyxal transpiles to python right

lyxal

Yes but the parsing is recursive if it has too many nested brackets

Unrelated String

but not with a small number of nested brackets?

lyxal

07:13

I meant to say "it's recursive no matter what, so more equals slower"

@Razetime this is correct

@hyper-neutrino if only they allowed multi-threading

StackMeter

07:32

hmm

what is this "multi-threading" you speak of

@lyxal please tell me how I thread a multi

lyxal

import multiprocessing

allows you to have multiple threads at once

StackMeter

ok

and what is the point of threading a multi

Razetime

it allows the vyxal site to run thing for multiple people at once

lyxal

^

StackMeter

ok

lyxal

07:36

but pythonanywhere doesn't allow it because it would complicate resource distribution

Razetime

instead of locking the site down when one person runs stuff

lyxal

a solution would be to migrate to heroku

StackMeter

@lyxal why doesn't it allow such a thing

lyxal

@StackMeter because someone could hypothetically cancel someone else's processes

StackMeter

ok

but why would processes not from the same user interact with each other

does that mean I could recurse infinitely and crash pythonanywhere for everyone

lyxal

07:38

no

because each person has their own resources

StackMeter

ok

@lyxal but if each person has their own resources

how would people cancel each other's processes

lyxal

explanation from the staff of the site

StackMeter

ok

your challenge; don't star this message

lyxal

sure

StackMeter

ok

also, the first code of the interpreter is being written

finally got off my butt and started writing

@xnor sup

lyxal

08:01

@hyper-neutrino there aren't really that many errors to begin with though

but I've added a bit more debugging

Step by step execution might be a bit harder to add

seeing as how it's transpiled and all

StackMeter

ok

that's fine

but at least tell us where things went wrong

Razetime

08:26

always worth cloning vyxal and running locally

cause it's generally faster

lyxal

Honestly I don't have a clue how to step by step a transpiled program

CMQ: would migrating my online interpreter to heroku be a good idea?

A username

09:11

@lyxal Probably. I mean, the alternatives are to either transpile it to JS (a big task) or set up a pseudo-multithread where you have several servers and it sends the code to the first available server.

Or can Python be async?

StackMeter

I don't think Python has async (also rhyme time)

would you accept zero-indexing on the first two dimensions?

Adám

That doesn't really make sense, does it? I mean, chess rows are always 1-indexed.

I guess the columns could be 0-indexed.

hyper-neutrino

true. i'm not sure it makes much sense either - was just wondering

Adám

On the other hand, the subsequent dimensions do have a 0, but also negatives.

In fact, I did kind-of modify the original, as the 4rd dimension only seems to have positive indices in the image. I can't make out the 5th.

@hyper-neutrino Meh, I'm in favour of leniency when it comes to I/O. I'll allow it.
