The Nineteenth Byte

@RedwolfPrograms In other news, Microsoft claims they haven't intentionally added a major security flaw to their laptops

8:30 PM

Major security flaw: We trust all of our money, communications, and military technology to bricks of sand

Luckily they mostly do what we want

I don;t know how sympy calculates matrix power for rational powers, but it seems to have bricked my Python :/

I got that and saw this

15

A: r flag my Vyxal

05AB1E, 15 12 10 bytes This could be 9 bytes without the l, but why would I remove that? SvyxaliŠìì Try it online! S # split the input into a list of characters v # for each character y: y # push y x # duplicate TOS and double the copy ...

:O

Hey there

welcome back o/

its been a while lol

8:38 PM

How're you doing?

good, collage is being a bitch though

My C++ won't write to a file like it should

@Christopher Too much glue? :P

How about you?

@cairdcoinheringaahing need to drink more of it and it would be fine

Good. Just got my first dose of the vaccine today :D

noice

Was able to get that a month or so ago

8:39 PM

I'm now 50% immortal :P

Just wait till the Covid 1.2 patch comes out, bug fixes and patches the vaccine exploit

@Christopher The way the US has rolled it out is crazy tbh

Yeah it was pretty nuts, i got an alert of my phone and was able to get it the next day. And i am not in any of the high priority groups

@Ausername I love that ovs went through the hassle of using <pre> tags in order to bold the Vyxal :P

Ux.....

Excuse me....

8:48 PM

Nice ratio

Yes

It also has a nice color scheme

They all do

Although they're colors that don't exist in the real world

Yes they do, on screens!

8:50 PM

Not the physical colors, the ones I see from synesthesia :p

1 is whitish, 8 is dark grayish, and 6 is a sort of wood colored brownish

Oh

@lyxal Can we have a flag for rational numbers in internal computing?

Don't encourage the flagssss

@Ausername Probably best to ask about this in Vyxal, but +1

This is an actually useful flag

Like O

Putting useful stuff in flags is what's problematic though

2

If the flags were like "make the stack flip all of the numbers upside down and feed them through an AI trained on roman numerals" I'd be fine with them

8:55 PM

@cairdcoinheringaahing wait, which one of these is a symbolic number lol

@RedwolfPrograms don't give lyxal ideas xD

@hyper-neutrino The *I is sympy's I, not Python's j

oh

lol, nice.

My secret is that I do not understand stack based languages

You can change the matrix and the power to try and get square roots, that just looks to be the shortest

Aaron Miller

@hyper-neutrino Too late, I'm gonna pass that one on :p

8:56 PM

@N3buchadnezzar Good luck with tacit then :p

shhhh

Stack based is super simple though, if you find it tough you're probably overcomplicating it :p

stack paradigm is easy even if individual stack languages aren't always

sshhhhhhhh

tbh whenever i'm looking at documentation for a stack language's builtins i can never keep straight what order the parameters are taken in

9:05 PM

Ooh, I just stumbled across a feature on MDN that was just implemented in the latest chrome version

Time to use it to yell at people with out-of-date versions :p

i can never remember if it makes more sense for TOS to be left arg or right

Terms of service?

The Oldest Son?

(can't tell if y'all're joking but if not - top of stack)

Oh :|

9:07 PM

I was close

(I was joking that it was terms of service, but I didn't know what it meant :p)

lol :p

i should just stop saying TOS. it seems like every time i use it someone doesn't know what it means so i end up spending more bytes to explain it than i would've saved :p

@hyper-neutrino You should add that to the top of the stack of your TODO list

Not sure if 4 2 - should be 4 - 2 or 2 - 4

They both sort of make sense I guess

i want to say that when you're stating arguments left being top makes more sense because you can think of it as, like, pop a then pop b then push a+b or what have you
but if you're writing out the stack itself then obviously top is right, because that would be the order in which the items were pushed

Q: Shortest code to take the longest to run

9:11 PM

Following reverse polish notation it should be 4 - 2

Write a program (in any language) that takes a really long time to run. wait or sleep blocks designed to take a specific amount of time to run are not permitted. Answers must be as follows: # language, bytes, time (secs) ## code ### machine running the code and other notes.

code-golf

@NewPosts Uh oh... This needs to be severely clearified

Heya Lynn =)

just take the factorial of like 3 million in python lmao

@hyper-neutrino Or try to do anything in Python. <- Joke about Python being slow

just do like 9!9¡9¡9¡9¡9¡9¡ in jelly and now this takes a few orders of magnitude longer than the lifespan of the universe to run

9:18 PM

An answer chaining challenge where each answer has to take longer than the previous one with a limited growth in size could be cool

@N3buchadnezzar ಠ_ಠ

@hyper-neutrino Fibonacci takes a really long time to run done recursively

fibonacci grows exponentially i think

factorial is faster isn't it? (as in, grows faster)

in any case, OP hasn't specified why while 1:0 isn't allowed

Nah, a bad implementation of Fibonacci grows as O(n!)

ah

rak1507

9:26 PM

@N3buchadnezzar isn't it 2^n?

Ackermanns is even worse, but we already had one of those

rak1507

2 branches for every n, 2^n

@rak1507 O(2^n) yes, sorry

ah. so exponentially :p (i think?)

Yes

9:30 PM

No way

I managed to inject code into a running Text instance

I can change the styling, at least temporarily!

@RedwolfPrograms Wait we talked about this earlier

Did we not mention css-tricks.com/… this in chat? scratches head

Unfortunately I don't think I can permanently impact the code, so it'll be a bit annoying, but I can now write a custom theme

I just have to do a few minutes of work manually to set it up

Honestly 100% fricking worth it

And if I like it enough, I might be able to download the compiled extension directly, instead of building it myself, then apply the changes there and install it normally

I've fixed the main issue I have with Text now. This is probably one of the best days of my life lol.

Really like this video youtube.com/watch?v=seVSlKazsNk. Have much more appreciation for Haskel now

9:48 PM

@hyper-neutrino None of us are joking, joking isn't here

:P

Text's default dark theme is truly something

ha, I see what you did there, that was very clever and original

Never have I seen such a horrible mix of colors

I just love the vomit green mixed with the very unnatural orange, it makes my JS look as bad as it should

Looks just like Molokai / Monokai

I think I'm just going to steal Github's dark theme and port it over to work with Text/CM lol

10:12 PM

CMC take in a list (of not necessarily numbers and assert whether all elements are equal. One byte solutions / builtins that are written explicitly for doing this is banned :p

i feel like there's probably a jelly 2 byter but i can only think of several 3 byters

Four bytes in Ash is all I can come up with :/

QḊ if we can return a truthy/falsy value inverted

oh yeah if course

i was thinking of something with Q but i completely failed to think of how to compare its length to 1

mu two other three byters were ṙƑ1 and Ṗ⁼Ḋ

Thought of an Ash two byter, something like Ṙz

(Check if length of unique items is one)

10:23 PM

@hyper-neutrino I dont know why but this APL presentation is helping me a lot understanding Jelly better youtube.com/watch?v=seVSlKazsNk

Well because Jelly is tacit like APL :p

...debatable how much like

but conceptually similar yeah

"(Jelly is tacit) like APL" not "Jelly is (tacit like APL)"

@N3buchadnezzar Scala: _.toSet.size<2

jelly's fixed adicity probably came up as sort of a hybrid of trains and whatever the non-train syntax is called come to think of it

10:25 PM

@N3buchadnezzar x=>new Set(x).size<2, or x=>x.some(n=>n!=x[0]) (reversed T/F)

oh yeah another fun jelly 3 byter is ḷ\Ƒ

@RedwolfPrograms Heh Scala good JS bad /s

@RedwolfPrograms For numbers only, - instead of != saves a byte

@RedwolfPrograms Please watch it when you have time =)

@N3buchadnezzar Python, 20 bytes: lambda a:len({*a})<2

10:31 PM

@LeakyNun I think I got 19 with a==a[::-1]

fails for [1,2,3,2,1]

Noooooo

that is literally just a palindrome check

CMC: Output n! (factorial) with all trailing zeroes removed, so 7 -> 504 and 10 -> 36288

Scala: 1.to(_).product+""replaceAll("0+$","")

10:41 PM

obligatory Brachylog, 3 bytes: ḟ↔↔

I assume the f is factorial, but what's ↔?

reverse

Ooh, that's smart

@LeakyNun I got 71 64 in Pyhon =/

so far the best i can think of for jelly is the very straightforward 5 byter with the one dyad i usually forget exists

10:49 PM

57 Could golf this 1 byte switching to python 2

@N3buchadnezzar 55

52: f=lambda n,a=1:f(n-1,a*n)if n else str(a).strip('0')

@user Clever!

@user 51

I think it is funny this is a struggle in Python because it is so expensive importing the factorial function bitwise :p

Jelly be like, what is this guys problem

10:53 PM

[here's a funny 7 byter in jelly](tio.run/##y0rNyan8/9/K9PD0R41brRwU////bw4A

i cannot type a right parenthesis to save my life holy fuck

@UnrelatedString I cant read this

floor-div by 5, multiply by 10, floor-div factorial by that

@UnrelatedString gives 181440 for 10 instead of 36288

...

and it doesn't work

yep

i literally thought to try that as you pinged me

cursed idea: a fixed-arity tacit lang where there are prefix and postfix monads and chaining structure depends on which way monads face

@LeakyNun Jelly, 6 bytes: !DUḌƊ⁺

10:56 PM

because it multiplies instead of exponentiating lmao

there we go

@hyper-neutrino Not enough D's

@hyper-neutrino i got halfway through writing that when i remembered t exists

oh i forgot about that :p

then !Dt0Ḍ :p

it is a very forgettable atom

@UnrelatedString outputs 155112100433309859840 for 25 instead of 15511210043330985984

10:58 PM

welp

looks like it manages to get two trailing zeros by 50

...

that is obvious in retrospect

whoops

counted multiples of 5 to count total factors of 5

stackoverflow.com/a/27631052/8037731 is probably the worst answer I've stumbled across on SO lol

wtf

And the worst part is it has three times more votes than the real answer

there's probably some way to do this with base conversion

uh

CMC: Given a positive integer n, output the n-by-n matrix formed by filling in 1...n^2 in ascending order. e.g. 3 -> [[1,2,3],[4,5,6],[7,8,9]]

11:14 PM

@LeakyNun easy 2-byter in Jelly lol

(spoiler in case anyone new to jelly wants to give it a shot)

@LeakyNun Scala: n=>1 to n*n grouped n

56 Cant really be bothered golfing it

I parsed HTML with regex and this is what happened

so far

No way, I can actually Text look nice by changing the CSS

11:27 PM

~~i'm not sure i can text look to begin with~~
