and although i don't use the u32s to their fullest i'm planning to add more stuff in the future
timid quartz
mf has "reserved" bits that will be reserved indefinitely
microsoft would like to hire you
spare quartz
:3
i also gotta make a generic package for bitfield enums
the PE file has approx 200 lines just dedicated to them
timid quartz
I gotta go destroy this exam in half an hour
spare quartz
i got my exam in an hour and 20 minutes :3
spare quartz
also
looks like the memory problem got pretty bad over 24 hours (repeatedly downloading a video)
195 mb is unacceptable
timid quartz
def gonna need to unchecked_deallocate the file chunks
or use a language that does it for you :3
like rust :3
spare quartz
or use a language that does it for you :3
ada is faster
spare quartz
i think its a good tradeoff even if its a bit annoying
spare quartz
im sure i could get it quickly up there by reloading a video with no cache
but im gonna try and use valgrind
timid quartz
valgrind should work
timid quartz
just deallocate your memory!!!
spare quartz
512 kb and flush the ends to the http request..
timid quartz
give into the use-after-free
timid quartz
give into the random program crashes
or you could be like the guy who was programming a missile
spare quartz
my computer is not an explosive
big difference
OH
there is one thing that i know causes a lower library problem in ada though that it doesnt catch
timid quartz
"yeah I know there's a memory leak, but I've mitigated it enough so that by the time it becomes a problem, the missile has either exploded or has otherwise become useless"
spare quartz
there is one thing that i know causes a lower library problem in ada though that...
quickly allocate and deallocate a C++ library
timid quartz
you should do that in a loop
spare quartz
i did
200 times
but the c++ library i was using was coded well
and threw a use after free error
timid quartz
code your own badly
spare quartz
sure and i'll also push it to a program 9 billion companies use
timid quartz
:3
spare quartz
oh yeah
with Ada.Containers.Indefinite_Holders;
with Ada.Text_IO; use Ada.Text_IO;
-- see if i can't commit use-after-free by keeping a Reference_Type's anonymous
-- access value around past its holder's lifetime.
procedure break_indefinite_holders is
type Thing is
record
name: String (1 .. 12);
end record;
package IH is new Ada.Containers.Indefinite_Holders (Thing);
function Funny_Business return access Thing is
use IH;
x: aliased Holder := To_Holder(Thing'(name => "abracadabra "));
begin
return Reference(x).Element;
end Funny_Business;
p: access Thing;
begin
p := Funny_Business;
Put_Line(p.name);
end break_indefinite_holders;
you can also technically use after free with this code
but that's kinda called for since you're using an access type
timid quartz
mf
//! Behold, a perfectly memory-safe use-after-free!
use std::hint::black_box;
use std::io::{stdin, stdout, Read, Write};
use crate::lifetime_expansion;
/// The size of the buffer we create and then drop.
const HORRIBLE_LEN: usize = 64;
/// Get a static reference to a dropped buffer.

fn get_horrible_buffer_mut() -> &'static mut [u8; HORRIBLE_LEN] {
let mut buffer = black_box([0; HORRIBLE_LEN]);
lifetime_expansion::expand_mut(&mut buffer)
}
#[inline(never)]
fn innocent_prompt() {
print!("Give text (must be at least {HORRIBLE_LEN} chars) > ");
stdout().flush().unwrap();
}
/// Reads data from a freed buffer, puts random data on the stack, then reads it again.
#[inline(never)]
fn innocent_read(initial_buffer_mut: &mut [u8; HORRIBLE_LEN]) {
let mut stdin = black_box(stdin());
println!("Buffer before writing:\n{initial_buffer_mut:?}");
let _buffer = black_box([0_u8; HORRIBLE_LEN / 2]);
let _thing = black_box(69_727_420_u64);
println!("Buffer after creating random data:\n{initial_buffer_mut:?}");
innocent_prompt();
// "Nah, I'd win." - Rust compiler
stdin.read_exact(initial_buffer_mut).unwrap();
println!("Buffer after writing user input:\n{initial_buffer_mut:?}");
}
/// Create a buffer and drop it, then read from it in `innocent_read`.
pub fn use_after_free() {
let initial_buffer_mut = get_horrible_buffer_mut();
innocent_read(initial_buffer_mut);
}

theres also people just spouting nonsense like elon/spacex/doge will fix it
spare quartz
like the system we have rn is robust and stupidly repairable 😭 how can you "fix" that
i love twitter
rustic vine
The existence of an efficiency department implies the existence of inefficiency, so I propose we get rid of doge
spare quartz
well it isnt a real department
just essentially a glorified suggestion box
doge suggestions or EVIL doge suggestions

Write fast python by writing as little of it in python as possible
It can be fast, just gotta let stuff like numpy do all the heavy lifting

Pythons great
Personal project
I usually use C# but errrrr .net
Could use C++, did make a basic game engine in that before

There is no other language which i can just start writing and know confidently there will be a package i can pull in that does 90% of the work

which means even though we're handling >1 gb throughout the progarm, only 1.9 gb is actually resident at a time

oh yeah fair enough
timid quartz
and store that somewhere
full berry
LOL
yes but how would you have the middleware check it lol
it would be weird if it just
checked a db if the key exists

the only reason jwt is good is because you can check it with a private key or whatever they call it

can't you just use an oauth like system for this
or at the very simplest

oauth.. for a roblox http request??

request (usr,pwd) ->

im not building a website or login im just doing api auth middleware
for
game data fetching and saving

oauth is for issuing keys so
it sounds the most similar to what you're asking for

what do you want

oauth is used to log into web apps, not backend calls

then why'd they want a way to "issue keys"
timid quartz
idfk
spare quartz
if they just want simple auth
timid quartz
poor word choice?
spare quartz
just use the Authorization header if thats all you want
full berry
yes
poor word choice i didnt mean to make a system to issue keys
just a way to check if the provided key is valid
lavish dove
It's dead simple to install and get content on the screen
I just remember it being worse than the alternative I had
spare quartz
just keep a copy of your user/password groups somewhere secure (encrypt if you want)
and send an auth header like Basic <base64 user:password>
full berry
i tried jwt its giga weird, they do it with like <jwt>.verify and you would pass in your secret
full berry
honestly aera the db thing might be intuitive it just feels a bit weird because it would be a double call to the DB, 1 to check the key and the other to fetch/write data
timid quartz
you can just cache the keys in memory then
function mainFunction() {
let keys = getKeysFromDatabase();
// ...
}
or whatever
full berry
oh you mean that
timid quartz
or store them in a .env file
timid quartz
and just don't commit the .env file to git

and just don't commit the .env file to git

what da flip is zed
some ide that was made by a bunch of nerds
i don't see the appeal in it personally
rustic vine
they made vscode with less menus
spare quartz
spare quartz
like i know these could have appeal to somewhere elsewhere but
- vsc/intellij are fast enough as is
- i don't really need ai
- i don't need real-time collaboration even with a team (git/telegarm is enough)
rustic vine
LLMs bruh
its over
copilot wrote some faulty code for a friend of mine on a project we were working on
and I didn't notice until like weeks later
full berry
what da flip is zed
minimalistic ide
mac and linux only as of now
full berry
you can build it from source on windows but it takes ages (at least for me)
full berry
their original aim was for it to be mac only
becuase it fits with mac more than windows or linux
rustic vine
at the end of the day I just be using vscode for everything except for heavy c + cpp, .net, and java + python
essentially just use vscode and whatever jetbrains has for the other ones
cause they are unfortunately just better
spare quartz
have you used vsc with wsl
spare quartz
do you know how to make the gpg signing not break when commiting
spare quartz
well because the key unlocking requires a password input in a tty
and the vsc commit button isnt a tty
i think it just kills itself preventing me from making a commit (other than manually doing a command for it)

spare quartz
the huh
rustic vine
for those statistics
avg is a decent number to look at but
usually what I really care about is
the 1% lows
spare quartz
avg isn't really a finished thing rn
spare quartz
yeah but im waiting until i add timescales to actually do more with them
since rn they're just hardset to an arbitrary number of samples
rustic vine
oh
cause a moving average is just a FIR filter
where the FIR gains are all just 1 / samples
spare quartz
i also need to factor in dT with the graph since it's reading every frame rather than a defined interval
spare quartz
cause a moving average is just a FIR filter
scary..................
spare quartz
yeah
spare quartz
ill probably add an input to allow the user to set the percentile of samples to use
rustic vine
and also finite difference is trivial too
(if you have a generalized implementation of a FIR/IIR filter)
spare quartz
yeah
spare quartz
the Averages table is going to be used for timescaling (1s, 5s, ...) but rn it's just "how many samples do you want"
(which due to the problem above with dT means the averages aren't over a time... which is the polar opposite of what i want!!!)
spare quartz
I didn't bother reading his proof its just vibes though
it was listed as an answer so it's infallible
rustic vine
yeah idk if thats the "proper" way of doing it
the only way I've done moving averages was either with a FIR filter
or by doing the convolution manually
I think I've used numpy.convolve for it
before
spare quartz
yeah idk if thats the "proper" way of doing it
it appears to give the right answers and does smooth out extreme changes so i think it's fine
of course still just a wip though
rustic vine
I wonder if it would match the 2 other ways of calculating average I listed
can you try

omg do youo know what NSA xkeyscore is
timid quartz
Do you know what grass is
spare quartz
no : 3
i walked a few miles 2 days ago and like
90% of the grass outside of my school district is yellowed/dead
timid quartz
Did you get burnt from the sun
spare quartz
surprisingly no
timid quartz
Did you recoil in shock like a vampire
spare quartz
i havent gotten a sunburn in years even though im like
super white
(i dont use sunscreen)

<@516049910622191626> hi I went to grab dinner
oh i just opened scpsl
ill impl after i die
rustic vine
I wouldn't be surprised to find out that the branching is actually slower than the loop
if the loop gets unrolled for n < ~10
spare quartz
the branch is probably transformed into a jump table so don't sweat it
rustic vine
there might be some funky or straight up errors if you use samples <= 2
I'll add a test and fix that now since you're in sl
nevermind it works
im the goat
timid quartz
okay i lived

made it better
and more tests!

if its under another child it will be constrained to the parent size
spare quartz
```lua

--!optimize 2
type Map<K, V> = {[K]: V}
type Array<T> = {[numb...
okay time to impl this
also question why do you do type Array<T> = {[number]: T} instead of ... = { T }
rustic vine
also question why do you do `type Array<T> = {[number]: T}` instead of `... = { ...
it looks nicer
😅
spare quartz
GA y
rustic vine
I like how Map<T> and Array<T> looks
spare quartz
i used to too...
rustic vine
in fact I have them aliased for the entire workspace in vscode
spare quartz
but now i just do plain {}s
rustic vine
also { and } is farther on the keyboard compared to < and > 🙂
spare quartz
local a = require(a)
local b = a(10)
while ...
b:compute(value)
end
i imagine this is how i use it?
rustic vine
yes
well
it returns the average
you can also call b:compute() to get the average again
spare quartz
you should probably add the return argument to the local function decl. of compute
but seems simple enough
rustic vine
yeah I usually do
spare quartz
alright impling it now
rustic vine
I guess I forgot

@spare quartz fixed the return types

is this frame under a screengui
It’s directly under a screengui and anchor,size,position are all set right
And it’s not updating when I change the viewport size 😭
spare quartz
there
should be impled
huh
OH it's on immediate sampling (0)
wait no same error
just made it skip over computing averages for 0/1/5
next error
top line in output is [Value, SampleSize]
ugh
its cause i forgot to update a var
spare quartz
nothing just a bunch of mini problems
rustic vine
how is that possible
spare quartz
how is that possible
changed the naming on something and didnt see the tiny orange line
rustic vine
And it’s not updating when I change the viewport size 😭
huh
no clue
ui design is my passion 😅
rustic vine
left is the math exchange equation, right is yours
so the same
wait
its the same except for one of them?
spare quartz
the exchange equation is more "volatile"
it changes for every value put into it
yours appears to buffer
rustic vine
can you assert(math.abs(a - b) <= 1e-6)
oh
that'll prob fail then
based on what you say
spare quartz
can you assert(math.abs(a - b) <= 1e-6)
rustic vine
yeah ok what I think is happening is
the stackexchange formula takes the average at the head
or no, at the center
whereas mine takes it at the head
so that means spikes in the underlying data is in phase with the average for the stackexchange method
whereas spikes in the underlying data is out of phase (average is behind) for my impl
thats my guess
its nice that the stackexchange way means you only store 1 number
thats kinda cool
spare quartz
and the source
(automatically assigned)
nice peak
and another shot
finally heres one with 1,000 samples
rustic vine
nice peak
yeah hm
maybe my conclusion earlier was wrong
@spare quartz oh wait
I just realized
spare quartz
?
rustic vine
?
I think the stackexchange answer is the same as sampling everything
so its not really a moving average
do you get what I mean
you hold onto the average forever and continuously change it
whereas in a moving average you only view a window of the past n samples
which means the average is exactly the average of the window
and not the average of everything to this point
spare quartz
and another shot
(note: the averages were complimenting each other due to an oversight in the code, updated to fix:)
spare quartz
yeah that makes sense
i was thinking of doing the sliding window approach initially
but didn't wanna hold onto thousands of samples given a long timescale/many selected elements
rustic vine
but didn't wanna hold onto thousands of samples given a long timescale/many sele...
each value in an array is 16 bytes
so its not really a big deal
until size gets crazy
an optimization that could be made is to use a circular buffer instead of the array
that would avoid the table.move call entirely
I didn't want to implement a circular buffer so
spare quartz
each value in an array is 16 bytes
wait what's the structure of an array element in lua
[???][8 byte double]
spare quartz
yes
rustic vine
its just a TValue
spare quartz
but what is that
rustic vine
but what is that
rustic vine
incredible
but yeah every single value in lua/luau is a TValue
even booleans are 16 bytes
timid quartz
also question why do you do `type Array<T> = {[number]: T}` instead of `... = { ...
HashMap<usize, T>
:3
spare quartz
`HashMap<usize, T>`
package Aera_Is_Babio_Question_Mark is new Ada.Containers.Indefinite_Hashed_Maps (String, Meow, Ada.Strings.Hash, "=");
rustic vine
what about strings
I think they are just an array of TValues?
spare quartz
I think they are just an array of TValues?
so many,,,,
strings in luau are UTF-8 right?
rustic vine
well cause it doesn't matter at the end of the day
rustic vine
oh ok
