The Nineteenth Byte

12:00 AM

I just installed Zsh and oh my god the autocompletion is so good

pxeger why didn't you tell us about this before?

Radvylf Programs

@user What's it like?

user

Radvylf Programs

Interesting

user

For one, you can choose with Tab if there are multiple options instead of having to type it out yourself

Radvylf Programs

Not really my sort of thing but seems neat

user

12:07 AM

This isn't bundled with Zsh and could be done in Bash too, but it's a whole lot easier to set up (the git plugin was in the default zsh config file after I installed it)

It also highlights commands that don't exist in red

Jelly can do it in 6 :P

Unrelated String

brute force or closed form

Zion mycelia adamancy

Closed form

Brute force is 8

Unrelated String

oh wait you posted the closed form formula in that spoiler link
i was about to write brute force then use it to check an attempt at deriving it :P

Zion mycelia adamancy

@UnrelatedString That was slightly off, it should be ((x + n - 1) choose n) / (x ** n)

Unrelated String

ah

Zion mycelia adamancy

12:36 AM

@Zionmyceliaadamancy Wait, no, that's wrong :/

Goddamn, don't make me go find my derivation notes

Steffan

Here's the formula: (x-n+1)*(x-n+2)*(x-n+3)/6/x**n

I think

DLosc

@emanresuA Here you go

Unrelated String

@Zionmyceliaadamancy yeahhhhh

Steffan

I was looking at quora.com/… and there's a clear pattern

Zion mycelia adamancy

Yeah, there's a simple closed form using sums

Steffan

12:37 AM

this uses sums

Zion mycelia adamancy

Basically, its the sum of the sum of ... the sum of the integers

Unrelated String

yeah

Steffan

yes

uses n(n+1)(n+2)/6

is what I sent correct?

Zion mycelia adamancy

Isn't that only for n = 3?

Steffan

It should be for all

Zion mycelia adamancy

12:38 AM

Cause that's just nC3

Steffan

I guess not

wait it isn't just (n choose x) / x**n?

x choose n I mean

that gievs the same results as my vyxal code

Zion mycelia adamancy

That'd make sense, I'd have just got my offset wrong

Steffan

I've been testing the formula on wolframalpha and it works fine

So the Vyxal code is now 4 bytes: ₌ƈe/

how to do syntax highlighting on a code block again

Radvylf Programs

Depends on what type of code block

For code fencing, just do ```javascript or w/e. For indented code blocks you need a comment of some sort

Aiden Chow

the <-- --> thingy

dont exactly remember how to type it out

it was like <-- language = python --> or smth like that

Unrelated String

the html comment for the language?

that's strange, it looks just as good as any other syntax highlighting

people often forget to use it though

Radvylf Programs

Orange, black, and blue is not my idea of a pretty color scheme

Steffan

Fine to me lol

Unrelated String

it's a nice subtly orange and blue though

For reference, this is what I customized T2xt to use:

Radvylf Programs

@RadvylfPrograms GitHub's dark color scheme is what inspired this

Unrelated String

okay i just installed one dark pro in vscode and that's so much better

might help that i was just using atom prior to this :P

Steffan

2:12 AM

Yeah the github theme looks fine, I wouldn't mind using it, but Dark+ is nicer

this is github theme

vs dark+

Yeah I'm not actually sure if I like One Dark or Dark+ better

@Steffan oh wow that really does give Atom vibes

emanresu A

Why is Visual Studio popular? It's incredibly laggy, slow to install/startup/run, takes up a lot of space, and is pretty much a subset of vscode

Steffan

it's not a subset of vscode really

it's meant for stuff like C#

.NET

Radvylf Programs

Steffan

windows app development

C++ too

Unrelated String

i feel like the extent to which visual studio is popular is the extent to which it just happens to be microsoft's ide for le microsoft language

lyxal

Wow I haven't used Visual Studio since I last touched VB.Net

And it was on a Windows VM on a mac too

Unrelated String

like i don't think anyone likes xcode but if you're writing swift on a mac you're probably going to default to using xcode

lyxal

@UnrelatedString MrXcoder begs to differ :p

Steffan

2:27 AM

probably just because of its integration with Swift

and if you're making an iOS app, you need it to run or build the app

lyxal

Plus it allows for testing without having to load to an actual device

Steffan

yes but you need Xcode to load it to an actual device too lol

Unrelated String

amazing

Steffan

you use an ios simulator

lyxal

@Steffan i know. I was saying in addition to loading on to an actual device

Man I haven't used xcode since 2018 when I made an ios app for an app making assignment. You could choose between app inventor for Android or making an app from scratch with xcode for ios. So while 99% of the class was drag and dropping in app inventor, I was Swifting my way through horrible constraint layouts

Unrelated String

2:36 AM

lmao

lyxal

I would have also chosen App inventor but the layout designer was just too restrictive

So instead I butchered relative measurements and so on to make something that only look good on the iPhone X

it has some patterns what with the superscripts, dotted letter series, etc.
