[rustic vine]

how is there cookies on a pdf

what da flip

[spare quartz]

THERE IS???

[rustic vine]

yes bruh

I had to accept a cookie terms

on a pdf

actually crazy

[spare quartz]

advertisers will stop at nothing

[rustic vine]

extremely low-power sub-1ghz rf transmit/recv

uhhh transmitter

goated name

[spare quartz]

neat

[rustic vine]

oh the name is CMT2300A

[timid quartz]

So hiragana ひらがな are native Japanese characters that map directly to the sounds you make when speaking

Katakana カタカナ are also native Japanese characters but are used for things like loan words, sometimes for emphasis, and a few other things. They’re basically hiragana but written differently as far as sound and meaning

Kanji 漢字 are adapted from Chinese because China was a major superpower and influenced all the countries around it. It’s also quite commonly used for words and stuff and honestly helps break up sentences visually for scanning. Like in Chinese, each character is a pictogram and has its own meaning. The “adaptation” comes from the fact that they don’t use the exact Chinese readings but instead map the readings to sounds in hiragana

[spare quartz]

wait what'd you read as the name

[rustic vine]

oh ok kanji is the one that looks like chinese

theres usually a few sprinkled in a sentence

so I can guess at the meaning sometimes

its usually similar!

(I think)

[timid quartz]

You had it almost correct, romaji is the term used for typing Japanese using Roman (English) characters

[rustic vine]

the ultra low power sub 1ghz transmitter

I was like wow kinda long and generic

[spare quartz]

interestingly it should say transceiver

[rustic vine]

oh

it do

[spare quartz]

ough

[rustic vine]

people use that for transmitter informally

people aren't proper 😅

[rustic vine]

wait so I get that they're for different things but why not just stick with 1?

isn't it more complicated to have all 3

chinese does fine with 1

or well, I guess we have traditional but 🤷‍♂️

[timid quartz]

Yeah because Kanji were adopted from the Han dynasty, the actual stroke order and meanings for the characters have drifted a little between Japanese and Chinese

[timid quartz]

I couldn’t tell you this

I think kanji are older and weaseled their way in because of China

[burnt locust]

I FORGOT ABOUT KATAKANA

[timid quartz]

And then for some reason they wanted a syllabic script as well

[spare quartz]

god i swear youtube is just getting worse

[rustic vine]

@spare quartz looks like its just a long spec sheet for the IC

[spare quartz]

50/50 the playback is just broken

[rustic vine]

if you have a specific part that you need translated I can help

44 pages though lol

[spare quartz]

alr thx

[burnt locust]

Yeah

[rustic vine]

oh ok

huh

is there stroke order

in japanese

when writing

[spare quartz]

pretty sure there is

[timid quartz]

Yes

For all scripts

[rustic vine]

oh ok

cool language

[spare quartz]

we need someone whos korean here now

[rustic vine]

it just seems complicated

[spare quartz]

then we can fill CJK

[timid quartz]

At least Japanese doesn’t have 4 tones that can change the meaning of words

[rustic vine]

they don't??

oh

thats not that bad bruh

[timid quartz]

I mean there’s pitch accent that can really help with understanding when speaking

But I don’t think it’s as necessary to meaning as the tones are in Chinese

But hey at least neither are Vietnamese

[rustic vine]

oh huh

im just glad we got simplified

traditional looks like a whole different hell

[timid quartz]

I know a guy who knows Cantonese

[rustic vine]

cool

[timid quartz]

And yeah

[rustic vine]

I never picked up anything

[timid quartz]

He says it’s harder lmaooo

[rustic vine]

lol yea

[spare quartz]

whats cantonese again

[timid quartz]

He says the benefit though is that every character has a unique sound so you don’t end up with homophones

[spare quartz]

i know its chinese adjacent but i got no ideda what it is

[rustic vine]

I lived in shanghai for a long time but never picked up the uhhh dialect or whatever

[timid quartz]

It’s the old Chinese

[spare quartz]

ah

[timid quartz]

Mandarin is the simplified Chinese

[rustic vine]

yea except all the sounds are completely different

yippppppeeeee

[rustic vine]

also this, that'd be cool if not for the fact I don't think these 3 really like each other

actually idk how korea feels towards jap tbh

but I know china has interesting relations with both korea and jap

[spare quartz]

GAAAAAAAAAAAAA

I CANTL ISTEN TO BAYACHAO

THEP LAYER IS BROKEN!!!!

[timid quartz]

[spare quartz]

no laguhing .

恨めしや

[timid quartz]

huh

where did you pull that from

[timid quartz]

ic ic

[spare quartz]

im gonna cry 😭

[timid quartz]

what phone do u have atp…

[spare quartz]

iphone se 2nd generation

[timid quartz]

u probably have a samsung

o

you struck me as an android user ngl

[spare quartz]

no ive been an apple user since i was 2

but thats cause my dad is an apple user

[timid quartz]

fair

im also mainly apple because of family and friends

[spare quartz]

i cant even listen tot his 😭

[timid quartz]

I got a really cheap pixel off of eBay for Christmas tho

so now I get to play with android

[spare quartz]

i need a new phone soon]

the battery/cpu on my current one are degraded

[timid quartz]

iPhone SE 3rd gen 💪

[spare quartz]

iphone se 4th gen

[timid quartz]

iPhone 17 Air :3

[spare quartz]

didnt they stop changing iphones since the x

wow

the 3rd gen looks identical to the 2nd gen

only difference is the addition of 5G support

wait it also has glonass

[timid quartz]

They made the notch into the “Dynamic Island” on the iPhone 14+

[spare quartz]

is that it

[timid quartz]

Other than internals and cameras yeah pretty much

Well

iPhone 16 they added a stupid camera button

[spare quartz]

at this point they should just make modular phones

[timid quartz]

iPhone 15+ I think they changed the little ringer mute switch into a programmable button

[spare quartz]

they still use lightnign,,,,,,,

[timid quartz]

I think 16 or maybe 15+ are usbc

[spare quartz]

i wanna check something

no way??

my eda has lightning connectors

[timid quartz]

Man why couldn’t the lightning connector have been the popular one

Isn’t it more durable than usbc

Because usbc has the prong on the inside

[spare quartz]

usbc has more extensibility

does lightning have PD?

[timid quartz]

PD?

[spare quartz]

USB power delivery

[timid quartz]

I’m talking about the actual physical design of the connector though

[timid quartz]

I mean…you can charge your devices with a lightning connector if that’s what you mean

[spare quartz]

yeah but PD allows for variable voltage

lemme get the pinouts

lightning on top, c on bottom

(EH pin is just the receptacle housing)

[timid quartz]

Yeah idk

I just wish the physical design of the lightning connector got popular

All it needed was more pins and for Apple to not have invented it/make it not proprietary

[spare quartz]

yesssssssss

give us the SCA-80 charger

all the pins

[timid quartz]

We need the 30-pin connector back

[spare quartz]

the one on old ipads and stuff?

[timid quartz]

Yea lol

[spare quartz]

mm idk

if they made improvements to how it latched then maybe sure

but everytime i used it the connection was flimsy

[timid quartz]

Obviously I’m not being serious that charger sucked

[spare quartz]

better idea

[timid quartz]

yessss

[spare quartz]

the old macbook magsafe charger was great too

[timid quartz]

Ok this is actually facts

MagSafe on the MacBook was peak

[spare quartz]

unironically great

[timid quartz]

They cooked with that 90deg connector too

[spare quartz]

it was a little heavy sometimes though

for sockets that didn't secure great sometimes it fell out

[timid quartz]

That’s cause the brick was yuuuuge

[spare quartz]

oh of course

https://youtu.be/YzBENUJtr1Q?list=RDbnRHL5Vq48A

this video plays fine but nothing else does

[timid quartz]

I dislike how the old chargers had the bricks and cables welded as one, so if one broke you had to replace all of it for like $80

[wraith scarab]

this is actually inefficient

you need to code better

adopt better techniques

[timid quartz]

Says the Python programmer

[wraith scarab]

whats python

[full berry]

hey whre am i

[spare quartz]

YOU'RE not supposed to be here

[full berry]

why

i own this group

i'm like the black suits of the US government

[timid quartz]

Hey where am I

[spare quartz]

you weren't submitted on the vip form

[full berry]

LOL

[timid quartz]

The what

[spare quartz]

the form you submit

for getting a vip seat

i COULD add you but ask speedy first or something

[timid quartz]

Oh eh idc

[proud creek]

You should add me so I can invade

[spare quartz]

no. you're already in light inc or whatever

[proud creek]

Isn’t it bbi as a whole

[spare quartz]

i dunno

[proud creek]

Ur making the event vro

[spare quartz]

okay but its not like i do everything

you and bbi submitted the vip forms not me

[lyric mesa]

why am i not there 😭

[steady seal]

This should do

[spare quartz]

do you wanna be on the list/has a directorate authorized you

(again the form passed to the people who made this list hadn't included either of you so..)

[burnt locust]

What is this

[wraith scarab]

true security

[spare quartz]

hey guys

i got my first pico today

im currently abusing an rgb led and i broke a cable

update

rgb leds

gfive you flash blindness

[pallid loom]

pi pico?

[spare quartz]

yea

[spare quartz]

also got a bunch of sensors/stuff with it too

IR rangefinder, LCD, and a servo

[pallid loom]

tbh the only reason i'm not using a pico for my projects is that it's programmed in py

and getting it to work with c++ could have issues

[spare quartz]

im planning to get ada on it after testing out my lcd

thankfully someones done it for me https://pico-doc.synack.me/

[pallid loom]

as atp does

[spare quartz]

🧌

[pallid loom]

you're like a rust user except ada

[spare quartz]

nuhuh......

[pallid loom]

totally not...

[spare quartz]

i2c beating my ass

[timid quartz]

Good

[spare quartz]

no.

using chatgpt pains me

but i got working code without a library finally

[timid quartz]

Just use a library 🗣️🔥

[spare quartz]

NO

oh god... aeras poisoned the lcd... 🤢

[spare quartz]

HEY IT WORKS

[timid quartz]

ada 👎

[spare quartz]

didn't you say durign the event.. every tp is a line of ada written

4 lines.

[spare quartz]

yeah

thatll add up .

oh if you include speedys dms thats like

20 lines

[timid quartz]

ok but I didn't say those were included

[spare quartz]

booooringggggg

[timid quartz]

I'll give you 5 lines for the initial request speedy made to get me tp'd

there's your 5 lines.

[spare quartz]

[spare quartz]

im spending too much time playing with the rangefinder

[full berry]

why is npm so weird

[spare quartz]

?

[full berry]

not related to what i originally said but

ugh you have to run so many things to publish it to a git remote

[spare quartz]

holy shitttttt

this doc is actually SUPER useful

the pi nano is the place i least expected ada to be great at but turns out the HAL they have is great

[pastel tinsel]

one word

runners

[pastel tinsel]

as for this

you can just do

export function bblahbk()

[spare quartz]

worlds least complicated linker line

dammit

[spare quartz]

stupid thing i wrote since i saw this tweet

it do work with varied input suprisingly

[proud creek]

why are your variable names already obfuscated 😭

[spare quartz]

thats just how i write them temp 😭

[proud creek]

decompiled script looking names

(i do that too when im lazy)

[spare quartz]

d = data
a, b = <temp>
t = table
o = output
i = index
e = entry
po = offset
agrt = aggregate

[spare quartz]

IS THIS NORMAL??

why is it letting me do this 😭:

[umbral monolith]

someone needs to investigate these universities.
because we can't do something we will NEVER do in our jobs?

[spare quartz]

honestly it's a really simple programming problem, but i'm not sure if the issue of people not knowing how to program is understated or overstated

[umbral monolith]

@spare quartz @timid quartz how would you guys approach this

https://youtube.com/shorts/F8aSFGoUuMg?si=Ut2vUN9Qv1ipNQTm

[full berry]

oh i saw that

[rustic vine]

I don't get his point

That trivial solution works fine for encoding any string that doesn't contain numbers

That problem doesn't exist no matter how many times it repeats

If you were to include numbers then you can just use an escape char like regex or anything else

\c for the literal char, and \\ would be a literal \

[snow oak]

NEW TYPESCRIPT PROGRAMMER IIBRIGHT2676 REPORTING FOR DUTY

[spare quartz]

if we're just going about the naive solution

then just make the repetition count fixed length (i.e. a byte or a short before each char) OR add a \0 OR save the repetition counts in a separate block entirely

as for the problem of delimiting that's not the compression algorithms job to diffrentiate

[spare quartz]

local source = "AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAABBB1111CCCDD"
local drain = ""

function lossless(source)
  local lastIndex, lastChar = 0, nil
  local out = { count = {}, chars = {} }
  
  for i = 1, #source do
    local c = string.sub(source, i, i)
    if c ~= lastChar then
      lastChar, lastIndex = c, lastIndex + 1
      out.count[lastIndex] = 1
      out.chars[lastIndex] = c
    else
      out.count[lastIndex] = out.count[lastIndex] + 1
      if out.count[lastIndex] == 255 then
        lastChar = nil
      end
    end
  end
  
  local drain = ""
  for i, count in pairs(out.count) do
    drain = drain .. string.char(count)
  end
  
  for i, c in pairs(out.chars) do
    drain = drain .. c
  end
  return drain
end

print("Source :", #source)
print(" - \"" .. source .. '"')
drain = lossless(source)
print("Drain  :", #drain)
print(" - \"" .. drain .. '"')

blocked naive compression

or, well, actually

you technically don't need the \0 to separate the block from the chars

since block size = chars size

aahhahah and that guy just used the output frrom gpt

[timid quartz]

@spare quartz thoughts on ktor

[spare quartz]

the kotlin web thing?

[timid quartz]

ye

[spare quartz]

i used it like once

it's okay i think

very flexible

unsure about performance thouggh

[timid quartz]

well it seems like an actual proper framework so I’m sure performance is less than like rawdogging tcp sockets

[spare quartz]

well i meant like

when i messed around with it some requests took forever

but i was probably setting it up wrong

rn im kinda just rotating a servo with my hands

[timid quartz]

I’m poking around with it right now for a potential QDF api rewrite and it seems kinda nice with these plugins for stuff like task management

[spare quartz]

i would say basic_http_server but like

the plan i have for that is just "port redirection" 💀

[timid quartz]

I’m writing this with two other people

We did Kotlin over Rust for ease of everything

Ain’t no way ima make them use Ada

[spare quartz]

😭

extensible_http is the library underlying basic_http_server but its essentially what you said: raw tcp

uhh, hope you enjoy kotlin though

[timid quartz]

why do u say that

what’s wrong with Kotlin lol

[spare quartz]

well

you're a rust user

idk your thoughts on it

[timid quartz]

I am a rust user yes

I mean at least Kotlin enforces nullable types and whatnot

Still prefer Option but it’s good enough

[spare quartz]

kinda

[timid quartz]

Exceptions……eh

[spare quartz]

there is nuance to the nullability stuff

e.g. interfacing with Java

[timid quartz]

yeah ik

You could probably coerce a Java function return to a nullable type tho

[spare quartz]

well

in kotlins eyes, everything sent to and from java has a ! at the end of its type

like say Int!

[timid quartz]

oh cringe

[spare quartz]

if where it came from isnt annotated with @Nullable or @NotNull

kotlin will compile as if it's not null

even though it may very well be null

so... be careful

[timid quartz]

Will keep in mind if I interface directly with Java

But I think we can get by with pure Kotlin

[spare quartz]

if you cocerce it into a kotlin type like say uh

val example: Int = javaInt()

kotlin will take care of null checks for you though

[spare quartz]

neat

[spare quartz]

oh and i know im kinda spouting a lot though but like

assuming you're using intellij take a good look at your settings for inpection, code style, compiler, etc...

intellij is very descript with what you can do with it/how you write with it

[timid quartz]

Yeah

[spare quartz]

i wondr if theres a luau plugin out yety

aw crap. why did i leavei t on this

[spare quartz]

oh yeah aera

i might take you up on that language server thing

i kinda wanna use intellij for ada/lua stuff instead of (bleh) rojo

[lavish dove]

there has been for a while

in vscode atleast

[spare quartz]

intellij

[timid quartz]

dewit

[spare quartz]

OK...............................................................................

but you have to write a jvm in response

-# /s :3

[timid quartz]

ohboy

[spare quartz]

okay so

helping another project with their lua and (since they use rojo and a bunch of other stuff)

i took a look at the language use in each github project

notably every single one i saw had rust along with ts in it

and im just thinking like

are ALL roblox dev apps just js users switching to rust??

[timid quartz]

Based

[timid quartz]

eugh rojo

[spare quartz]

yeah rojo is writteni n rust

like every single program is for roblox dev and i have no idea how

[timid quartz]

Based

Rojo is gross though

Why are you adding some git bullshit on top of Roblox studio when you can just use studio and "version" your changes by either writing down what you did or using "Save to Roblox"

[spare quartz]

cause they wanna use vsc

duh

[timid quartz]

I used rojo once

The world's clunkiest experience

It's just so unnecessary and doesn't integrate smoothly at all

[spare quartz]

additionally

every single one of them use the same command line library (afaik)

minor differences but

[timid quartz]

yeah it's probably clap

[spare quartz]

do ALL rust projects use the same library

oh

[timid quartz]

I mean usually there's some variance but generally if you're looking for something there's like 1-2 good libraries

sometimes more

but normally set of ones that are good and actively maintained is small

[spare quartz]

i wont argue that this is a bad thing (in ada we really only have Ada.Comand_Line and GNAT.Command_Line which are sufficient)

but its just so surprising to see they're all almost identical from the outside

[spare quartz]

(ex.)

wonder what adacores formatter looks like

oh yeah darklua devs

PLEASE make a -k arg

i dislike the 500 errors it prints out in every single file it fails to convert

waow

[rustic vine]

Git is objectively better at version control, so i think there's at least some validity there

My main reason for using it is for vscode support

Not having to launch studio to work on stuff is nice

Especially when you're on a laptop

[timid quartz]

ok but like

you're gonna want to test your shit

and you have to be in studio to test your shit

[rustic vine]

Not really

[timid quartz]

mm yeah really

[rustic vine]

There's automated testing if you really want, and otherwise the typechecker is usually good enough to guarantee correctness

[timid quartz]

scripts that don't interact with the workspace or anything else in a roblox place are basically nonexistent

[spare quartz]

p. .s

[rustic vine]

Then I'd argue you're writing your code wrong

But scripts that interact with the datamodel are testable too

[rustic vine]

[timid quartz]

ig this is true

[spare quartz]

do i remove the dbug todo

[timid quartz]

but inevitably you're gonna call a function that tries to workspace.something

[rustic vine]

Up to u

[spare quartz]

also verify your comm its

[rustic vine]

That's a lot of work

[spare quartz]

nuh

[timid quartz]

dude in what world do you spin up roblox just to write code that doesnt interact with the workspace at all

[spare quartz]

unless you mean signing already made commits

[timid quartz]

unless you're atp and writing a jvm

[rustic vine]

Right, but keep datamodel interactions explicitly separate from logic. You do all the work in an ecs world and then reconcile it with the datamodel separately

[spare quartz]

ecs internals

[rustic vine]

Essentially the goal is that you can very explicitly test behavior of the ecs world separate from the roblox datamodel

[timid quartz]

sounds like a buncha nerd-type over-complication shit

just write your code smh

[rustic vine]

You can also test end to end using open cloud if you really wanted

[rustic vine]

😅

Chill on the

Complication, its not actually that bad

[rustic vine]

As in, if your project is fully managed by rojo, it can build the rbxl of it in CI and run the place in studio completely in the cloud

Kinda cool stuff, I don't think it's worth it for most projects though

[rustic vine]

I mean setting up signing in general

[spare quartz]

oh no its not

just get gpg, attach it to your git config

[rustic vine]

Oh

[spare quartz]

here

[timid quartz]

me when I'm logged in with a different email than my gpg key so all my commits show up as unverified

[spare quartz]

the humble retroactive signing w/ interactive rebase and git push force 😈

[timid quartz]

is there any way to even like

same gpg key different email

cause I really don't want a third gpg key for bbi

[rustic vine]

Make initial commit and just keep amending it with new changes 😈

[spare quartz]

linux kernel in 1 commit ez

[rustic vine]

Fr

[spare quartz]

unsure

[rustic vine]

Don't think so

They're tied to email on creation iirc

[timid quartz]

ugh cringe

[rustic vine]

Just don't sign

Ez

[spare quartz]

all programmers should sign or be faced with stalin sort

[rustic vine]

Whoever impersonating me would probably write better code anyway

[rustic vine]

Stalin sort??

[rustic vine]

Do you starve 80% of the elements until they get in order

Oh

Genius

[rustic vine]

Also to this point, how was it clunky?

I find its mostly ok nowadays

Only gripe is it not actually killing its subprocess under vsc when I ctrl-c it

[timid quartz]

Idk it just seemed to never want to sync to studio quite right

I used it years ago

So it's probably gotten better

[rustic vine]

Oh, yeah, probably

It's mostly seamless now

[timid quartz]

Also like

How similar is an ECS to like MVC or MVVM

@rustic vine @spare quartz

[spare quartz]

WHAT!!!!!!!

idk anything about any of those terms i just write

[rustic vine]

You can't really compare them too well

Ecs is primarily used for games

[timid quartz]

I didn't think so

[rustic vine]

Mvc/mvvm is mostly related to presenting UI

[rustic vine]

Although they all try to reduce the coupling needed in doing what they want

[timid quartz]

I have only ever touched MVC/MVVM for one class lmao

[rustic vine]

Yeah i don't think they're directly comparable

Ecs is cool though

[timid quartz]

kinda weird to understand at least for me

[spare quartz]

same

[timid quartz]

probably because I mostly do backend and embedded

[spare quartz]

im just a smarter search and replace rn though

[timid quartz]

Arent we all

[rustic vine]

It's distinctly different from oop but also shares similarities

It's much much more data oriented

[timid quartz]

It's seems like you'd use OOP as a means to an ECS

[spare quartz]

oop can facilitate ecs yeah

[timid quartz]

like entities would be classes, components would be interfaces

[rustic vine]

Kinda? The data is structured differently

And thus makes behavior more easily composeable

[spare quartz]

...

huh

i just remembered an old project i made in neco

lemme try to find it, some type of ecs-like system i came up with

[timid quartz]

what would ECS code even look like

I feel like I'd understand it better

[rustic vine]

The main benefit I've encountered is just how decoupled everything gets

[spare quartz]

some old code but ill just send the model here

[rustic vine]

I can share some once I'm on my laptop

[spare quartz]

i dunno if this constitutes a true ecs system thing but

yaeh

[rustic vine]

AHHH ATTRIBUTES

Evil code that uses attributes

They fumbled attributes tbh. Could've been great

[spare quartz]

yeah this code uses attributes for local state a lot

e.g.

[timid quartz]

Seems like ECS systems use loops a lot

[spare quartz]

in AnnunciatorElement

[timid quartz]

Inefficient...

[spare quartz]

its dated 04/04/2024 😭

i gotta stop writing code

[timid quartz]

I’m personally a huge subscriber to “event-oriented” programming

no pun intended

[rustic vine]

Systems can run every frame (most do)

[spare quartz]

i do the same

[rustic vine]

Ita not inefficient in any way though

[rustic vine]

Event-based
> look inside
> while loop long polling

[spare quartz]

> look inside
> giant array
> for _, v in array do v(...) end

[rustic vine]

LOL

[timid quartz]

ok but like….if the events are implemented in an engine id imagine its more efficient

[rustic vine]

Not necessarily. Every operation in the ecs library I use on roblox (ecr) is faster than it's equivalent table operation

[timid quartz]

library 👎

diy 👍

[rustic vine]

For example world:get() is faster than table[key]

[spare quartz]

you shouldn't be saying this as a rust user

your language is a library

[rustic vine]

And world:set() is faster than table[key] = value

[spare quartz]

how does world:get() work

[timid quartz]

So is yours smh

I don’t see you writing directly to stdout

[spare quartz]

System.IO :3

idk how the lower level ada io functions operate though

[rustic vine]

reads an index in a contiguous array

[spare quartz]

they're present in all environments but idk how that translates since not all of them have stdouts

[timid quartz]

I think I’m getting to the point of not using libraries until I decently understand what’s going on underneath though

[rustic vine]

I think that's a fine argument to make

[timid quartz]

There’s some exceptions like a Discord lib which in essence is a wrapper around a http client but

[spare quartz]

oh, its faster than dictionary reads?

[timid quartz]

A discord library is also giant

[rustic vine]

But i could also argue i use libraries because I dont want to understand how it works

[spare quartz]

waaiiiiitttttttttt no, buffers

right

[timid quartz]

That’s also fair

[rustic vine]

Yep. No cache misses

[spare quartz]

i just enjoy writing libraries even if i already know how they work

[timid quartz]

I definitely shy away from libraries in Nix though because I don’t want to be reliant on them in case I have to do some shit myself

[rustic vine]

A combination of that and normal arrays yeah

[spare quartz]

neat

[timid quartz]

Harry have you ever heard of Nix

[spare quartz]

dont listen to aera harry

nix is a curse

[rustic vine]

No i get that, just sometimes I want to write feature code not library code for 2 years first

[timid quartz]

It’s a curse but you can’t go back once you see the light

[spare quartz]

(or 1 day!)

[rustic vine]

Is it that one venv that can do everything or something

[rustic vine]

1 day is 1 day

[spare quartz]

iirc its like you turned a TOML config into a linux distro

[spare quartz]

yeah i have like 20 of those left

easy math

[rustic vine]

Huh

[timid quartz]

Kinda yeah? It’s a package manager built around solving the dependency hell problem by having each package pull its own specific dependency versions instead of relying on shared libraries

What this enables is programmatically-defined reproducible builds

And NixOS extends that idea to the entire OS

You can also make devshells which is probably the venv idea you were referencing

[spare quartz]

what are venvs again

the like

[timid quartz]

Virtual environment

[spare quartz]

little encapsulated envrionments you download libraries and binaries to to use for one project

oh my god i cann ot see

[timid quartz]

{ pkgs ? import <nixpkgs> {}
, stdenv ? pkgs.stdenv
, autoPatchelfHook ? pkgs.autoPatchelfHook
, fetchzip ? pkgs.fetchzip
}:
stdenv.mkDerivation {
        name = "gprbuild-myself";
        version = "22.0.1";

        src = fetchzip {
                url = "https://github.com/alire-project/GNAT-FSF-builds/releases/download/gprbuild-24.0.0-2/gprbuild-x86_64-linux-24.0.0-2.tar.gz";
                hash = "sha256-CvUz3UpZw07RoFrA3k8dYc8KUOhN610LlYn0UW43k24=";
        };

        buildInputs = with pkgs; [ glibc gnat ];
        nativeBuildInputs = [ autoPatchelfHook ];

        dontConfigure = true;
        dontBuild = true;

        installPhase = ''
                runHook preInstall

                mkdir -p $out/bin
                cp bin/gprbuild $out/bin

                runHook postInstall
        '';
}

Like for example

This makes gprbuild

{
  description = "Ada agony";
  inputs = {
    nixpkgs.url = "github:nixos/nixpkgs?ref=nixos-unstable";
  };
  outputs = { self, nixpkgs }:
  let
    system = "x86_64-linux";
    pkgs = nixpkgs.legacyPackages.${system};
    gnat_external = pkgs.gnat14;
  in {
    devShells.${system}.default = pkgs.mkShell {
      packages = with pkgs; [ alire gnat13Packages.gprbuild glibc ] 
        ++ [ gnat_external ];
      shellHook = ''
        alr toolchain --local --select gnat_external=${gnat_external.version} gprbuild=18.0.0

        export PS1="\[\e[1;32m\][\u@\h:\w]\$\[\e[0;0m\] "
      '';
    }
  };
}

This is a development environment for ada

And if you have Nix (and an x86_64-linux system because I was too lazy to add support for more but it’s easily doable) then you can just use either of these

[spare quartz]

AAAAAAA

[timid quartz]

@rustic vine

[spare quartz]

wait

is this based off of JSON

[timid quartz]

idk tbh

It’s its own DSL also called Nix

Idk where Dolstra (the guy who made it all in a graduate thesis) got the inspo from

[timid quartz]

Which is kinda ehhh, unlike Guix which was inspired from Nix but uses GNU Guile which its its own programming language

So in theory you can use Guile for stuff other than Guix

[rustic vine]

I went to grab lunch mb

[rustic vine]

oh hm, interesting. I know I used to use repl.it and they switched to nix/nixos? for everything essentially

[rustic vine]

probably, that makes sense

[rustic vine]

huh. I don't quite get whats the advantage of doing this? you still end up pulling a release from somewhere eventually down the line no?

is it just so you get extremely fine grained control over what exactly fetching/installing a dependency does?

contrary to like a more, dare I say, "feature complete" package manager that attempts to do a lot of things for you?

[timid quartz]

Yeah you do but with the inputs.nixpkgs.url you can specify the exact point at which to pull from Nixpkgs

[timid quartz]

And yeah replit uses nix under the hood

[timid quartz]

Oh well that example you replied to isn’t a flake so it just uses your system’s current Nixpkgs version

[spare quartz]

wow okay

not used to this new explorer

[timid quartz]

There’s this weird divide between “flakes” and “non-flakes” right now because flakes are technically an experimental feature but were kinda pushed for wider use and a lot of people have adopted them because they let you control what specific versions of things like Nixpkgs to use

[timid quartz]

Nix is still a package manager and still does a lot for you but the entire draw is reproducibility because you can take a Nix file and get the same output anywhere with Nix, basically no more “it works on my machine” problem

[spare quartz]

honestly i like how alire does things

just wish it were more stable

[rustic vine]

ok but docker

who needs nix

when I can just ship my machine

[rustic vine]

oh alr

[rustic vine]

I would react to this with a 👍 but I can't react

terrible news

[timid quartz]

Because nix doesn’t virtualize

[spare quartz]

promote this man rn

admin abuse

[timid quartz]

Nix gives you native binaries

[rustic vine]

fr

get me promoted asap

[spare quartz]

just like alire!!!!

[timid quartz]

Docker also isn’t a complete “it works on my machine” solution especially if you’re using like a debian or alpine container and using the package manager in them

You could also be using a :latest container and get problems there

[proud creek]

why did replit have to lower their free specs so much smh

[timid quartz]

They kinda solve different problems

[timid quartz]

Idk

[proud creek]

https://cdn.clipake.me/u/bOtGC5.png like i didnt even use it that much

hm

i should check if theres a gnat-14 windows compiler out yet

[timid quartz]

gnat_14 is on Nix :3

[spare quartz]

yeah gnat_14 is everywhere

but i need a cross compiler

thanks riscv

[timid quartz]

oh a cross compiler

lame

[spare quartz]

ughuguuhgh

its so frustrating

i just wish i knew how to build gcc without it like

erroring and making binaries that don't even work

[timid quartz]

Too bad Nix isn’t available on Windows or you could cross compile with that :3

Though cross compiling with Nix is kinda aids

Just like it is without nix

[spare quartz]

WAIT

NO WAY

THEY MADE ONE

[timid quartz]

lame

[timid quartz]

Now compile gprbuild and gnat with that

And use those to compile your project

[spare quartz]

hold

checking gprconfig

[rustic vine]

oracle free tier absolutely cracked

[spare quartz]

mmm

[rustic vine]

btw

just saying

[spare quartz]

gprconfig isnt reporting ada...

[rustic vine]

I've been using it forever

[spare quartz]

hopefully its fine

[rustic vine]

they give u like 2 vcpus

[timid quartz]

yeah if you’re able to get a server on it

[rustic vine]

wdym able to?

[timid quartz]

You talking about the Arm ones?

[rustic vine]

yes

[timid quartz]

Those are like constantly unavailable

[rustic vine]

oh fr?

i remember when i used to do that

i barely got anywhere with cloud stuff thuogh

ughughughghg

why cant you see it

[timid quartz]

Just use gprbuild directly stoopid

[spare quartz]

wh

what do you think alr is doing 😭

[timid quartz]

Not finding it when you know where it is

[spare quartz]

this is a gprconfig issue

[timid quartz]

oh uh

[spare quartz]

stoopid

[timid quartz]

Use gnat directly then

[spare quartz]

okay sure...

lemme just build 30 files manually

[timid quartz]

Or just like make windows vm and build there

[spare quartz]

but thats lammmmmeeeeee :<

fine

[timid quartz]

Cross compiling anything is a pain in the ass

Make it less of a pain in the ass

[spare quartz]

gimme a sec

i have to setup alr

[spare quartz]

i dont get it though

how is cros compiling to a developed os like windows or mac

1000x harder than like

a pi

[timid quartz]

[rustic vine]

@timid quartz heres an example of a button system (on the server), theres prob a lot going on but you're welcome to ask

this is completely testable on its own and doesn't rely on the datamodel at all

[timid quartz]

LOL

“SEND AS FILE PLEASE SEND AS FILE PLEASE SEND AS FILE PLEASE”

[rustic vine]

ay man

you gotta do what you gotta do

[timid quartz]

Interesting

[timid quartz]

Yknow you can like click the + and do “send message as file” right

At least on desktop

[rustic vine]

oh

no, I didn't know

[timid quartz]

This doesn’t feel like it would scale well

[rustic vine]

😅

[rustic vine]

why not?

[timid quartz]

Like if you have hundreds of buttons

[timid quartz]

Your :iter() is gonna take so long

[rustic vine]

nope

[timid quartz]

Hundreds or even thousands

[rustic vine]

I already have hundreds of buttons

and I think its under 20 us

[timid quartz]

what the shit

[rustic vine]

lol

[timid quartz]

if you were to just do that with a for it’d take so long

[rustic vine]

it is with a for

wdym

the for loop isn't the slow part

[spare quartz]

(i'd know, the game draws entire images with them at game start :3)

(but ricard hasn't id verified so they're useless)

[rustic vine]

LOL

evil code that does evil things

[spare quartz]

nah just film grain

its noise

[timid quartz]

well duh it’s the stuff it does

But even if you have tasks inside that take like 2ms, over 500 items that adds up to 1 whole second

[rustic vine]

but yeah idk if you saw this but

world:get() is faster than table[key]
world:set() is faster than table[key] = value
and more

every single ecr (the ecs library) operation is faster than its equivalent table operation, while using less memory

[rustic vine]

sure, but to that, just write better code

[timid quartz]

And then there are nested for loops in that

Which is even worse

This is literally O(n^2)

[rustic vine]

in what

[timid quartz]

wdym in what

[rustic vine]

you said there are nested for loops in that

idk what you mean by in that

[timid quartz]

Oh wait I misread

The script

Still it’s not great to have like 5 sequential loops

There’s a way you could mush that into one loop

[rustic vine]

there is, yea

but theres not really a reason to

maybe save you say 5 us

luau is awesome in that the most idiomatic code is typically the fastest

the loops query different components anyway, so its not a big deal

their overlap isn't big I don't think

[timid quartz]

Still worst case your :exclude could not exclude anything

Like sure you could amortize it but

[rustic vine]

thats fine

the only stuff in the loop is like

an if statement, a fastcall, and then registry calls

those are insanely fast

I think its easy to be skeptic of code that runs every frame because it feels like wasted compute, but its really not that much different (or in any way always worse performing) than event driven code

[proud creek]

Editableimage moment !!

They’re really cool tho

[spare quartz]

hold on im trying to furrify an icon

[proud creek]

What.

[proud creek]

[spare quartz]

its worth it bro

take my umm

ball

[spare quartz]

amortized is a funny world

i dont know what it means

[timid quartz]

Uh well in the context of computer science some algorithm's runtime could be said to be amortized

So like in the beginning it may be inefficient but as it keeps running it gradually gets better

Or like kinda

basically "on average" it's something

So like the runtime for appending to an ArrayList is amortized to O(1) because most of the time you can just slap the new value right at the end

but every now and then you'll need to incur an O(n) resize

so it's not entirely O(1) but you can "amortize" it to basically say "yeah most of the time it's O(1)"

[spare quartz]

oh

so thats how they make those funny big Os for algorithms

a lot of stuff i write i cant figure out the complexity of cause they're usually quite variable

[timid quartz]

Ehh kinda, you usually can't or don't amortize

Big-O is the worst-case runtime for an algorithm and it's defined in terms of the inputs

O(1) is constant time, meaning the algorithm takes the same number of steps no matter how large the input
O(n) is linear time, meaning that the number of steps increases linearly with the input size; think of a for loop
O(n^k) is polynomial time; think of nested for loops

There’s more but that’s the gist

Obviously lower Big-O is better, so like O(n) is better than O(n^k)

So really the way that you come up with a Big-O for an algorithm is by analyzing what it does

[rustic vine]

Alternatively you just profile n benchmark it 😅

Happy new year btw yall

On the topic of time complexity though, sparse sets are the most goated datastructure known to man

Sparse sets are
O(1) add
O(1) remove
O(1) contains
O(1) clear
O(n) iteration
AND Contiguous in memory

[timid quartz]

but isn’t that the same as a hashmap with a goated hash function

well ig clear would be O(n) but

[rustic vine]

Yeah clear would be O(n) and also it wouldn't be contiguous in memory so iteration will incur more cache misses

[spare quartz]

😈

theoretically if you avoided fragmentation you could do it in O(1) by deallocating memory

oops misread

i have some notes written down

@spare quartz do you know lua?

i can show you my notes

see if they're good

[spare quartz]

• don't use wait, use task.wait
• don't use game.Workspace, use workspace
• don't define variables without local
• don't define functions without local
• ideally save the output of FindFirstChild to a variable and refer to it if it exists

[burnt locust]

Alright

[burnt locust]

so how would i go about that last note

[spare quartz]

local Humanoid = hit.Parent:FindFirstChild("Humanoid")
if not (Humanoid and Humanoid:IsA("Humanoid"))  then return end

...

or

local Humanoid = hit.Parent:FindFirstChild("Humanoid")
if Humanoid and Humanoid:IsA("Humanoid")  then
  ...
end

[burnt locust]

ill be streaming some random dvelopment and just general playing around in vc

if you wanna join

[spare quartz]

doing ar t

[burnt locust]

alr

[burnt locust]

hey why isnt this working

so

in the last if statement

its meant to set it to that position if the variable position = 0

but its not doing anything

[spare quartz]

is script.Parent anchroed

[burnt locust]

uh

yes

[spare quartz]

well then its gonna offset the opsition not set it

in that post

also wait() is officially deprecated

[timid quartz]

_G ❤️

[pastel tinsel]

Kill…

_G is only good if you are like checking if something has been already ran somewhere else

[timid quartz]

if not _G.ThingDidTheThing then
  _G.DoTheThing()
end

[pastel tinsel]

Or just return

[rustic vine]

I'd argue that you shouldn't use it at all, in any situation

[pastel tinsel]

yeah

Understandable too

[rustic vine]

There's always a better solution than using _G or shared

[timid quartz]

I use _G for like one script I paste into the dev console lol

_G.ThingRunning = true;
while true do
  if not _G.ThingRunning then break end;
  -- ...
end

so I can control when to stop it

[rustic vine]

Oh yeah, dev console and command bar is a different story

I said that in the context of anything else

on: reordering structs

crying with GNAT rn… he can do literally all of that while maintaining programmer controlled representation:<

[timid quartz]

me when I just #[repr(C)]

[spare quartz]

Ada users when the Pack, representation clause, Size, Alignment and Export => C come in

[timid quartz]

#[repr(C)]
struct MyStruct {
  field1: i8,
  field2: i8,
  field3: u16
}

[spare quartz]

I’m not writing the Ada equal since making a strict clause is so hard on mobile

for X use record
      field1 at 0 use 0 .. 7;
       ….
end record;

but something f like that

[timid quartz]

the ada equivalent is just

with Interfaces; use Interfaces;

record MyRecord is
   Field1 : Signed_8;
   Field2 : Signed_8;
   Field3 : Unsigned_16;
end MyRecord with Pack;

that's what I'd imagine

and Export => C if you really want

[spare quartz]

I don’t know if Pack definitely tells the compiler not to reorder though

It’s just a flag saying “optimize this for space over perf**”

[timid quartz]

#[write_qdf_bot(for_me)]

So easy

i was thinking rustrover but i don't feel like moving to enterprise software until i at the very least get a basic grasp of how rust works

VSC?
