IIRC Finite Brainfuck with only 3 unbounded cells is TC

yeah i think 3 cell unbounded brainfuck is just a register machine
whatever the actual term for those is

Damn, Kamila has had an impact on the field of esolangs

i think that's just something she put there since the existing literature didn't have anything terribly convenient

IIRC The Amnesiac from Minsk has also been used to prove the TCness of multiple tarpits

@UnrelatedString Still, that's her name attached to something

yeah

a cyclic tag system is probably the simplest

Also I/D machine is really simple but unlikely to be usable when other things aren't.

Blog post feedback, again?

1:38 AM

for the lilypad problem this is a solution

\sum_{y=1}^{z}\prod_{v=1}^{\operatorname{floor}\left(\frac{\operatorname{length}(X)-y+z}{z}\right)}\left[X\left[i\right]\operatorname{for}i=\left[y,y+z...\operatorname{length}\left(X\right)-z+1\right]\right]\left[v\right]

but

the probem is it doesn't work when step>half of lilypad length

i'll try fix it

Oh jeez you don't know confusion 'til you start hearing windows 10 notification sounds on your chromebook and it turns out some video was autoplaying in the background really quietly and they didn't turn on do not disturb before screen recording it

Have I done a good job with the language bit? (I tried to use "learn an interesting langauge" partially as a segue into my existing piece about golflangs)

1:57 AM

smart

oh maybe add prolog to the "rare practical language" list

Sure

Should I link to Wikipedia, Visual Prolog or SWI Prolog?

i have no idea what visual prolog is so probably swi

might see if swi has a good beginners page somewhere

okay they do

Is the conclusion too small?

"Time to use Regex with C on windows" - He said, Clueless.

Hey guys is this what y'all mean by "sandbox"? Am I doing it right?

2:05 AM

Yes.

i looked up visual prolog and what the fuck is it not actually a microsoft product
it's proprietary and only runs on windows, and it has "visual" in the name for no discernible reason, but it's not actually microsoft

(just had to get the image size small enough lol)

@emanresuA it's a bit small visually but i can't think of anything else that needs to be in there

Can has another underappreciated answer or two?

@ATaco Oh...oh no

i can see how they might be trying to piggyback on the reputation of microsoft's "visual" line but... why would they want to associate with that

2:52 AM

i've discovered a new thing that i really hate

when people make nightcore versions of songs but change them by not a multiple of a semitone so the result is no longer aligned to the western tuning system

yikes

That's a big ouch.

Sometimes it's nice not knowing anything about music because when everyone's panicking 'cause the music is broken I just hear the music-y noises and it's good enough

the real question is does it sound worse than this

@RadvylfPrograms well the thing is since I don't have perfect pitch it usually doesn't matter to me

it's only because i started trying to transcribe it for piano so i pulled out a tone generator to tune it to the song and realized it was right between Gb and G

@UnrelatedString what is this

2:59 AM

Sounds like you need to re-tune the song first.

well i mean, i could just transcribe the original, which is in Fm, lol

i haven't played persona q but afaik there are some sections where you play with the cast of 3 and some sections where you play with the cast of 4
the standard battle theme for each is mostly the same composition, but in different keys and with different female vocals
so this is one pitch-shifted to match the other and overlaid on top of it, then that the other way around, then both at the same time

it's absolutely awful and i love it

@hyper-neutrino wait why are you transcribing nightcore for piano

i like the nightcore version better (possibly only because i heard it first) so i was gonna listen to that one to transcribe it

but since it is offset from the piano i will just do the original lol

ah

lmao

what song btw

yeah i can see how the nightcore could work better there
and i'm saying that as someone who generally does not get the appeal of nightcore

still good though

to be fair, the first time i heard this song was in nightcore, so the original sounds slowed down to me lol

it sounds somewhat slowed down to me and i haven't heard the nightcore lmao

because it's just kind of slow overall

lol true

anyone help me explain why?

LOOONG TEEEXT Definition of long text Long text usually shows emphasis, for instance, loooooool or yaaaaaaaaaay. Usually the vowel is replicated many times. In this challenge we require: At least 3 times, which means yaaay and yaaaay are allowed, but yay and yaay are not. Consistent, which mean...

code-golf

did you by any chance sandbox that

yes

@OldSandboxPosts hello

reminder

I would've forgotten i did that

@UnrelatedString yes

It was

ah

well i guess i need to look at sandbox posts more often because i can't think of any particular problems with the challenge itself but it took me way too long to realize it's an open-ended-function

also the treatment of capital letters should probably be explained explicitly

3:22 AM

OK

@UnrelatedString done

what would eE become?

eee, Eee,eeeEee...?

eeeEee

aight

also does the repetition count have to be the same across all inputs

no

How I got here I saw a few sites of Stack Exchange elsewhere. Exactly where I forgot, but it made the first impression of Stack Overflow to me: they were indeed very sophisticated. I learned about Code Golf Stack Exchange (which I will shorten to CGSE) when something led me to this link: Produce ...

discussion new-users cgcc-blog

@NumberBasher i was about to post this until i realized it wouldn't hit the minimum of 3 for an input of a single vowel

does Ee become Eeeeee then (assuming x3)?

as in, the deduplication only works if they're actually identical?

yah

wait

i think i found something

like if you send the same thing twice

they become one

so

this

yeah you can't send the same message twice in a row too quickly in SE chat

3:34 AM

^

they aren't merged it's just blocked

this is good because sometimes when your internet is bad it'll attempt to send multiple times and so it's good that the server deletes the extra attempts

this is, however, bad because sometimes I want to say the same thing twice in a row

sometimes

also it even applies if the first message was deleted

the way discord does it is just by attaching a nonce to each instance of the user pressing the "send" button, so if bad internet causes multiple attempts, it'll just ignore the rest, but if the user tries to send the same message multiple times, it'll go through

@UnrelatedString --- .... / --- -.-

oh that's smart

3:35 AM

so idk if SE intentionally is spam blocking by doing this (which doesn't make sense with how heavy the ratelimit is), or if they just didn't realize they could use nonces

@UnrelatedString i'm pretty sure it's standard (or at least somewhat common) procedure to avoid duplicate actions when sending modification requests :P as in like anything but GET

anyways

i just installed a morse keyboard and forgot to switch...

maybe just a subtle way to prod people not to spam short messages when they could use one longer message

except it's independent of the rate limit

i mean, usually people spamming short messages won't be using the same exact phrase, lol

ah, i misread the issue. maybe it's a client side thing to reduce load on the server?

how long will this be a hot meta post? hmm: chat.stackexchange.com/transcript/message/61164757#61164757

please stop asking

i can remove it if you want though

... is it even a hot meta post anymore? i can't see it in the sidebar.

4:11 AM

i think so; there are more hot meta posts than can fit on the sidebar and it rotates through them if my observations are accurate

given that it shows me the option to remove it i assume it still is

It feels kinda awkward putting one of my own answers in the underappreciated posts section for the blog post I'm writing :P

So, anyone else have an underappreciated post or two?

I think all my posts are perfectly appreciated.

@JoKing oh ok

Someone named "Anoni Mouse" sent me an email

and I want to know who he or she is

he or she told me he or she was from SE

...They?

@ATaco ?

wdym

They is a good alternative for "He or She" as a singular non-gender-specific pronoun

And this is why we don't put email addresses in posts

@ATaco OK

@JoKing i do, but i'm a little ... erm.... lazy to change it

alright I wouldn't personally recommend that but that is up to you ¯\_(ツ)_/¯

i never understand what that emoji means

shrug

@PyGamer0 CMC: Encode morse.

4:52 AM

actually its ¯\_(tsu)_/¯

CMC: given text, encode it into morse, and then decode it from morse

Vyxal, 0 bytes

why?

Given text, Determine if it's Morse. If it's Morse, decode it, otherwise, encode it.

@emanresuA ???

@ATaco you can encodde morse

decode this

4:53 AM

@NumberBasher because if you encode and decode the result will be the same

@ATaco ooh that's an interesting one actually. what's the required format in that case, for something to be considered valid morse

Whilst one can, it feels redundant to encode morse as morse.

@ATaco it's a good thing

For purposes, Morse code is defined as "Any text containing only . - / and whitespace".

does the actual validity matter? as in what do we do with --------------------

4:54 AM

Assume input is valid morse if it contains only . - / and whitespace.

@ATaco what is the / ?

@hyper-neutrino TTTTTTTTTTTTTTTTTTT

Non-valid morse is outside the scope of the challenge

@hyper-neutrino or this: ............................................................................------------------------------------------

/ seperates words, whitespace seperates letters.

4:55 AM

@emanresuA bad chars are bad

ah. so it either contains only .-/ and is valid morse, or contains at least one other character

~~do we encode or decode the blank input~~

morsedecoder.com

@hyper-neutrino hmm, that's easy

Theoretically it is decoded, but it decodes to an empty string.

4:55 AM

yes it was a rhetorical question

Actually tempted to make a challenge out of this.

since it really does not make a difference whether you encode or decode it

does vyxal have morse code built-ins

it does not. feature-request time?

We do already have a Decode and an Encode Challenge seperately, it seems.

@hyper-neutrino i wonder how likely you will use it

is there a challenge to decode ambiguous morse code, i.e. without the spaces

4:57 AM

sorta

Yeah

huh, i was more thinking of outputting all possibilities, but that works too

@ATaco CMC: Construct a morse code string that can be ambiguously parsed by the specs of this challenge.

the dictionary file has been link rotted, so...

ah, frick

5:02 AM

i mean, presumably any two words that can be concatenated into a larger word would qualify

like into

@JoKing Outputs should be different when spacing is removed

or the first comment that suggests an and eg

welp, that's simple

oh wait, "EG isn't in the word file"

@JoKing oh ok

use regex to implement regex, duh

Working on Funky3. I want to use Regex as part of my string library, but I need it to be fully portable.

Which is painful

how many features do you plan to need

like are you shooting for full pcre or

POSIX is too... different imo

And tiny regex doesn't have groups which feels like a deal breaker

can make your own flavor if it would feel less insane

That's the level of C programming I fear to be on.

It's one thing to implement a Hashmap instead of using a library. It's a different beast to Implement Regex.

python also has list comprehensions and the lambda syntax is more verbose anyhow

ato.pxeger.com/…

i.e. you're going to use list comprehensions unless you've got a function already

@UnrelatedString if only there were two lectures pygamer could have attended that covered functional programming :p

@PyGamer0 doesn't js also have a forEach that's specifically for calling something for just its side effects
