The Nineteenth Byte

@dzaima LOL.

@Zacharý sad thing is I don't need it in java 10

Actually, THAT is one of the reasons that () should be used instead of <>: >> confusion!

12:14 AM

@Zacharý I'd find )) not working as confusing as >>

@dzaima )) is not a separate operator. >> is (bit shifting)

@Zacharý well > is also an operator, but it's not getting confused there is it

@dzaima Even more reason to not use <>!

@Zacharý but parentheses can be confused with function calling, scope division & argument lists :p

@dzaima That's why !(...) is a thing.

Or, if you wanted to do something insane, make templates equivalent to higher-order function calls.

12:25 AM

@Zacharý why have 2 syntaxes for the same thing?

@dzaima It signifies compile-time evaluation of the template arguments, that way it can do type-checking and the like.

The best template syntax I've seen is Fortress's double-struck [ and ], no ambiguity there!

I can't imagine a scenario where <> generics would be ambiguous

there be the code. Warning: Java, and very little amount of implemented built-ins, or things in general.

I've noticed that people have these answers with a certain format, where there's a link to the language

I doubt that everyone's finding the language's website and linking it all themselves

Is there some sort of tool for formatting PPCG answers?

TIO I think.

12:35 AM

@Mendeleev TIO has it

hm

You have been ninja'd

oh hey that's still a thing

@Mendeleev Did you think it wasn't?

12:36 AM

@Zacharý I haven't been here for a year(chat suspension) and wasn't sure if the injokes had changed

Oh, @dzaima, thanks for providing me with a bug to fix: the test case that works in your APL clone, it should work in RAD, but doesn't (even after I replace a with A). It's not assigning anything to A for some reason.

@Mendeleev Welcome back! The injokes really haven't changed that much ... from what I can tell.

Thanks

also since a year has passed since March 2017, I'm free to change my username on PPCG

@Zacharý :|

:45850111 Yeah, in March of last year I was changing my username to something unrelated really often (see my chat profile) and I said I wasn't going to change it for a year

@Mendeleev well y'see ninja-ing isn't a PPCG-specific thing

@Mendeleev oh

12:43 AM

is "eleven" still used

chat.stackexchange.com/search?q=eleven&room=240

not since april apparently

@Mendeleev Outdated.

@ASCII-only That actually wasn't the cause: for some reason the unicode converter isn't working right.

facepalm I forgot to handle APL-aliases in the fromASCII (bad name, I know) function.

@Mendeleev WheatWizard/CatWizard/HatWizard/<something>/WW changes his name and profile picture constantly.

@Zacharý but it's always wizard related

i think there was one point where the username was "Sorghum Sorcerer"

Also Cart Manager XD

12:49 AM

@Mendeleev I'm referring to any new "injoke"s.

@Pavel Eh?

@Zacharý Used to be Wheat Wizard's name

@Zacharý I see

Also gÓEûùIÿ at one point

Never mind about forgetting to handle APLiases in fromASCII, that would also transliterate them in strings.

@Pavel That's what I meant by <something>

And What Wizard

12:54 AM

@Zacharý :||||||||||||||||\

@ASCII-only Basically: APL ≠ Greek.

1:05 AM

@dzaima How long does it take to run?

Oh, and ngn actually does show up in chat, that's something new since you got suspended ... I think

I did not meant to ping him.

@dzaima Mine takes ~8 seconds to run... yeah, I eventually need to make it not horrible at parsing stuff.

@Zacharý ~14ms

@dzaima ._. yeah, mine sucks.

@dzaima Are trains implemented?

@Zacharý no, but it'd be a simple addition

Yeah, I need to get rid of that O(n^2).

dunno why I deleted that ._.

1:10 AM

lol

I think I've done enough RAD for today. ⍺⍴⍵ and ⍺μ⍵ aren't going to be easy to implement, so I'll save them for tommorow.

running the exec 100000 times averages to 0.04617ms per execution :D

@dzaima Running the exec? The executable for the interpreter?

@Zacharý for (int i = 0; i < 100000; i++)exec(t); where exec executes APL

Yeah, I'm NOT going to attempt to run RAD a large amount of times.

After RAD is on TIO (which will be after more atoms are implemented), I'll work on making the tokenizer and evaluator not slow as all hell

1:40 AM

@Zacharý :|

Yeah, I know.

1:54 AM

@Zacharý tokenizer and evaluator, what else is there :P

@quartata Evaluator & parser are in the same function for RAD.

Anyone here know if it's possible to upload SVGs to chat? I've never tried

@quartata yes.

Interesting dilemma

on to more pressing matters

how often does everyone here eat

Anonymous

Anonymous

Oh I missed the word "often"

Anonymous

2-3 times a day

2:01 AM

you had me very concerned. thought i had been doing your Grammar wrong this whole time..

That would have been very bad

@quartata 4 times a day not including occasional grazing and tin can consumption

thats quite often

do you eat the tin out of the ground

is that where you get it

@quartata ew no wtf what do you think i am ~~im not an animal~~

well you said graze. it means graze grass right

you can it from organic, non-GMO, responsibly sourced tin can producers

2:08 AM

ah.

everyone seems to have a lot of Industry, these days

everything is farther away from the Earth. more steps.

non-GMO? how does that work

@quartata obtained from bacteria that naturally produce tin cans

@quartata the micro-bacteria that naturally exists in tin can is not genetically modified

but we all have been genetically modified

is it about who did it. did @jack do the modifying

yes but we want bacteria that has been GMO'd by goats not evil human

Thats downright relatable.

just one more quick question

what is a goat.

Someone asked me, on the channel with the cat thing, if i wanted to be a goat. they tied up the line and wasted my time. but it made me realize, we dont have "Goats"

we had Oats, used to. Is this a linguistic drift

2:13 AM

@quartata just imagine the best animal and then that is a goat

Oh, I would never do that

>:U

Imagining the best creature, the best person, is how we all got here

and now we're all trapped.

RAD is just a hack, built on top of a hack, built on top of a hack, ...

@Zacharý which hacks specifically

@ASCII-only Value, tokens, and evaluate.

tokens and evaluate are hacks?

5:02 AM

By "hack", I mean horrible. O(n^2)

@Pavel this sounds related to line rider for some reason

@Zacharý lol, charcoal's is the same, i think?

@ASCII-only I don't think so. Charcoal isn't slow as f**k for anything complex.

This took ~8 seconds to run in RAD.

@Zacharý well it's at least O(n^2) for sure though

profile your code pls

@ASCII-only What do you mean by that?

@ASCII-only Then how the f**k is it so FAST?!

@Zacharý parsing usually isn't the bottleneck, apparently (this is true for most mainstream languages too - they use handwritten parsers)

@Zacharý well it does have 0.3s startup time, which is super slow :P

5:08 AM

@ASCII-only Mine is sort-of handwritten, it iterates through substrings >.<

O(n^2) combined with regexes.

@Zacharý substrings?

		for(ulong i = 0; i < j; i++) {

Like above

@Zacharý run a profiler on it >_>

@Zacharý explain in simple pseudocode pls?

WTF is a profiler <_<

@ASCII-only "ABCD" would cause it to search "ABCD", "BCD", "CD", "D", "ABC", "BC", "C", "AB", "B", "A" until it found a match

@Zacharý ...

@Zacharý tells you how long the code spends on each part

well to be more specific, usually it's each function

5:14 AM

@ASCII-only I know exactly what slows my code down. It's those two horrible functions.

@Zacharý ok so why do you need to do this

@ASCII-only 'Cause I don't really know how to parse. That's why I used modgrammar in the Python version >_<

@JungHwanMin I mean you can't really forget golfing ideas, which I'd expect to show up while checking sandbox posts. As long as you're not already writing an answer with those ideas, its fine

CMP should 2⍴(1 2)(3 4) return (1 2)(3 4) or 1 2 in RAD?

@Zacharý I feel like 1 2 would be the most logical thing but there should be a reshape type thing that does 3⍴(1 2)(3 4) = (1 2)(3 4)(1 2) too

@dzaima Maybe I can use ϼ for that.

also, ⍬2⍴⍳6 → (1 2)(3 4)(5 6)

No! That could easily be 3 2⍴⍳6.

@dzaima ⍴⍵ already does weird stuff with ⍬.

@Zacharý but then I have to calculate the 3, storing the ⍳3 in a temporary variable

2Σ⍳6

@Zacharý that doesn't allow customizing - what if I wanted 2⍬⍴⍵? Or 2⍬3⍴⍵?
