[spare quartz]

whats this? a roblox clone?

if it allows standalone game dev im all for it

[rustic vine]

https://www.overdare.com/

I think it's experimental

[spare quartz]

i thought the roblox engine has always been nice, it's just the coupling to the platform that's a huge limiter

[rustic vine]

It's ue5

[spare quartz]

mmm

not a great sign

[rustic vine]

LOL

Yea, it's kinda sketch

[spare quartz]

existed for 5 yrs by now so

at least its not a popup

looks korean?

https://www.krafton.com/

appears to be under these guys

woah, they made pubg?

okay a lot less sketchier, but, still dont like that platform aspect

[proud creek]

the workspace naming is the exact same as roblox lmao

[spare quartz]

i can put that aside if they actually let you do anything outside what roblox provides

can't patent a hierarchy

[timid quartz]

@spare quartz @rustic vine holy shit the OS exam murked me and the compilers exam was strait ass

We ARE NOT making it out of the hood with this one

[spare quartz]

????

what'd you get wrong

[timid quartz]

On OS? A lot

On compilers? Idk yet I took it this morning but a decent chunk of it probably

https://youtu.be/3e-nauaCkgo

[spare quartz]

it SHOULD'VE been ada

[timid quartz]

waah waah waah let your language fade into obscurity

[spare quartz]

no!

pass your stupid os tests and compielr tests

rust iss till a stupid languege

[timid quartz]

ada is a stupid language

smh

[spare quartz]

no you know what is stupid

these fucking mosqutoes

i keep being bit

THERE IS ONLY ONE LANGUAGE THAT CAN DO THIS ALL TODAY

AND ITS ADA

ITS ADAAAA

BBBAawwWLLL

😭

[spare quartz]

okay

our bootloader works... kinda

might be overwriting the transfer buffer causing the ret addr to be trash

[rustic vine]

😭

[rustic vine]

lock in bruh trust

[spare quartz]

ugh im gonna give myself brain damage

[rustic vine]

it ain't looking good I'm scared to take those classes myself

[spare quartz]

qemu appears to be loading the correct entry, but our simulator is loading a directory entry..

[rustic vine]

feels like you're so much smarter and are still getting cooked so im gon be in the trenches

[rustic vine]

whole lotta numbers

[spare quartz]

we dont have a proper debugger yet so im just requesting byte by byte to check

[rustic vine]

very good 👍

thats the approved method

[spare quartz]

anyways not trrue you'll both do okay..

~ an uneducated person

[rustic vine]

u smart too

I be over here playing with luau while you're making a computer

I think

[timid quartz]

thats what im saying

atp over here doin crazy shit

[rustic vine]

LOL

[timid quartz]

meanwhile im just idot

[spare quartz]

okay well thats because i traded my education for "infinite" free time

[rustic vine]

feelsbadman

[spare quartz]

and you actually know the theory and crap ...

[rustic vine]

me when I pull out my 4 years of theory experience to the recruiter

[spare quartz]

me when i pull out a sub-high school diploma and NO experience 😭

[rustic vine]

ok but I don't got a computer to my name

[spare quartz]

i mean they're easy to make...

everything in programming is... its just "do you have the time"

[rustic vine]

or the willpower

I be having all the time and still do nothing

lol

kinda

nvm thats an excuse, I def have time if I wanted to do something

[spare quartz]

well you know a LOT more about luau than i ever will so

thats something

have you tried to make your own vm yet

[rustic vine]

yea but luau is going going and gone (into the trenches)

also kinda

[rustic vine]

no but its on the list of things I want to do but just haven't yet

[spare quartz]

oh

[rustic vine]

(its a long list)

[spare quartz]

well if you ever get to it i wanna see it so i can "take inspiration off it" (recode it into kotlin and shove it into our bios as a casette BASIC)

i could never get into lua vms since it's not clear where 2 start

on secnod thought

thats a lie

[rustic vine]

just ask this guy

[spare quartz]

asking people is scary

[rustic vine]

or dig into this

[spare quartz]

oh i was thinking more this

[rustic vine]

oh, a runtime?

runtimes are cool, that one is in rust though I think

[spare quartz]

ohh

[rustic vine]

so it gets negative rep from you

[spare quartz]

i might have to code our interpreter in..

asm..

[rustic vine]

theres also one in zig

which is sick

[spare quartz]

cause that would be the easiest to embed

[rustic vine]

a friend of mine made it

https://github.com/lodinukal/cart

[spare quartz]

is there like

a definite list for what a luau vm consists of

or a list of opcodes

[rustic vine]

yes

[spare quartz]

can i see it 🥺

ignroe >> 0x0000E800

lua is risc??

(esi is probably not being offset)

OR SECTION HEADERS ARENT BEING LOADED

[rustic vine]

luau is open source lol
https://github.com/luau-lang/luau/blob/b0c3f40b0c23682376c90d3e16eff57b81367870/Common/include/Luau/Bytecode.h#L56

[spare quartz]

yes i was on it, it just wasn't clear what connected to what immediately

[spare quartz]

i like my specifications...

[rustic vine]

yea writing one is made more difficult by the fact that

[spare quartz]

that isnt a lot of opcodes

[rustic vine]

theres no c api docs

but the lua c api docs exist and are kinda helpful for most cases

would be nice if luau had some

[rustic vine]

its not, yeah

[spare quartz]

so two more questions... sorry if im annioying yo u:

• does luau have anything special over lua from a pure vm standpoint (excluding CG, opts), like does the vm itself carry anymore state
• how much state does the lua vm itself have

e.g. an x86 vm can have it's state captured entirely by the values of its registers, while a JVMs state depends on it's heap of classes, their static values, the call stack,. ..

[rustic vine]

no all good, I was just doing something else

• yea, the vm does have extra state, one example is continuations being done slightly differently in luau compared to lua 5.3, since luau diverged from 5.1 and then continuations changed past that
• take a look

[spare quartz]

oh wow its just called state.h

[rustic vine]

yes

and check out this

it supports ncg too

[spare quartz]

peculiar

[rustic vine]

hm? whats up

[spare quartz]

i just didnt expect to see it work that fast

[rustic vine]

oh gotcha

[spare quartz]

a lua compiler/interpreter in one package is going to be so painful to make

computercraft uses this

https://github.com/unmojang/drasl/

[spare quartz]

making a replacement to this

[spare quartz]

that isnt the right image

i love self aligning code

[spare quartz]

my favourite programming language is rust (that's because my code never segfaults (unless i'm doing something especially silly))

[rustic vine]

U ok?

Sure you aren't being held at gunpoint?

[timid quartz]

atp has finally seen the light

[pallid loom]

[timid quartz]

ur not a rustacean are you?

[pallid loom]

i'm not

[timid quartz]

gross nobody constrained you to use a certain language

That means you get to use Ada

[spare quartz]

i actually asked him

if he wants it fast/low resource (ada) or written fast but more resource (kotlin)

[proud creek]

Lua

[spare quartz]

no

[timid quartz]

@flint belfry I hope you know that a normal VPN server will be more performant and secure than any code ATP could churn out

[spare quartz]

😭😭😭

im literally about to get the main loop done

[timid quartz]

With the added bonus that it’s available right now and you don’t have to wait for it to be implemented

[timid quartz]

Listen I’m all for you having coding projects even if they’re in Ada but when it comes to a VPN or similar application that users expect security out of, it’s your little toy implementation vs well-tested (hopefully open source) projects with years of development and improvements

[spare quartz]

you... do realize im not using my own tls lib right

not 2 mention he explicitly asked me cause the others didnt work

not to mention age isn't really a factor in programs

sure it means it's kept up to date, but programs written today have something they didn't have back then: hindsight

[timid quartz]

I feel like there’s more to VPN security than just the TLS

[spare quartz]

like?

trying to figure out why windowws isnt porting to linux rn

[flint belfry]

it doesn't need to be powerful

i found out socks5 can work since ssh supports it but like

it's kinda jank

[spare quartz]

got something,,

[timid quartz]

Also Ada doesn’t even have any TLS libs

You just have WolfSSL and that’s it

[spare quartz]

we do

we have bindings

:3

[timid quartz]

rust does too

[spare quartz]

TLS is just uniquely hard to implement

[timid quartz]

AND we have rustls

[spare quartz]

rustls kinda sucks ngl

a lot of times i see your crates just defer to "native-tls"

[timid quartz]

a lot of times I see crates offer the choice

[spare quartz]

and guess who they defer to by default?

[timid quartz]

ur mom

[spare quartz]

die

[timid quartz]

nothing gets through her she’s too big

[timid quartz]

Bad lang

[spare quartz]

Bad user ^

[timid quartz]

worst user ^

[spare quartz]

no

thats the best composer who ever lived.

ああああ our beloved

[timid quartz]

they probably would choose rust over ada

[spare quartz]

NO

actually we have proof bayachao/poshi/aaaa dont

their latest game?...

it's coded in js :3

[timid quartz]

still better than Ada

[spare quartz]

NO!

[timid quartz]

yes

👍

[spare quartz]

shameless

no brain

all rust

[spare quartz]

OH CMON

@timid quartz so

the SSTP client im using to test this server

i tried sending it a status and

😭

this would NOT happen if it were made in ada

[timid quartz]

Wouldn’t happen for rust either

[spare quartz]

nope, it WOULD happen

[timid quartz]

correct it wouldn’t happen glad we agree

[spare quartz]

errmm.. blind

ugh whyyy1y?!?

[timid quartz]

Would not happen smh

[spare quartz]

Write your own :3

[timid quartz]

die

[spare quartz]

goddd

it keeps segfaulting

im convinced this thing just isnt compliant

[timid quartz]

Oh what

This is a different sstp lol

[spare quartz]

ehh

https://crates.io/crates/sstp

yeah

some guy name steve 😭

[timid quartz]

fr

what is sstp

[spare quartz]

Secure Socket Transfer Protocol iirc

MS-SSTP since its made by microsoft

Tunneling Protocol*

[timid quartz]

mmmmm

can’t really find anything

[spare quartz]

:3

[timid quartz]

maybe find a better protocol…

[spare quartz]

like..?

[timid quartz]

idk openvpn

[spare quartz]

thats giant

[timid quartz]

Or tell Kade to like idk

Set up his own https proxy

And just use that

[spare quartz]

but thats not a vpn

[timid quartz]

close enough cause 99% of the time he’s gonna be web browsing

[spare quartz]

if he wanted a proxy he should've been upfront because that'd make my job 1000x easier

[timid quartz]

Or just like idk tell Kade to get gud with setting up openvpn

Or tailscale

Skill issue tbh

[spare quartz]

what is a tailscale........

everytime that name is brought up i lose all memory of it

[pallid loom]

Wireguard but with a central server

Tailscale acts as the relay in-between when port forwarding isn't possible

[spare quartz]

ohhh

[pallid loom]

And wireguard itself is a VPN protocol that's the fastest + is quantum protected

[spare quartz]

so its a proxy router

[pallid loom]

In ~3k lines iirc?

[pallid loom]

In a sense

The client you're trying to connect to connects to tailscale servers via wireguard

Since only the host needs to have the ports forwarded

(in this sense, tailscale relay)

[spare quartz]

this is why i dont like product names... way too unmemorable for me

[spare quartz]

what is the language it is in?

(barring the fact that loc/language is irrelevant when talking about a protocol)

[pallid loom]

forgor

look it uo

has a whitepaper

[spare quartz]

ohh

so its like IKE

[lavish dove]

why do I keep running into so many problems with qemu

its so frustrating

works in bochs, real hardware, qemu fails inexplicably

oh I forgot to use kvm instead of qemu64

[timid quartz]

yeah @flint belfry just use wireguard smh

or tailscale

[spare quartz]

finally

got it to not segfault

problem was the client is too eager to data and attempts to read off a buffer beyond points that haven't filled yet instead of polling

at least thats my theory

[spare quartz]

implementing the P2P protocol now

[timid quartz]

ssl verification failed 👎

isnt that the point of a vpn

[spare quartz]

thats the fault of the certs im using dummy

[timid quartz]

👎👎

get someone else to sign your cert nerd

[spare quartz]

nuh uh

[spare quartz]

also the point of a vpn is just to get remote access to something like an intranet

[timid quartz]

why does @flint belfry not just use wireguard

or tailscale

[spare quartz]

security only came later, you can see this with PPTP

SSTP came after PPTP to provide security and access with only HTTPS

[flint belfry]

/dev/net/tun dosent exist on said os

[flint belfry]

tailscale is based off wireguard

so wont work

[timid quartz]

you're using windows??

[flint belfry]

no

[timid quartz]

what os are you trying to run this on

[flint belfry]

obscure linux os made for some sort of processor

company name freescale

dosent even have a package manager

[timid quartz]

???

[flint belfry]

so i need to compile source code

[timid quartz]

is this like

your school's computer or some shit

[flint belfry]

no

all school computers run windows

which CAN run wireguard

but thats not what im trying to do

[timid quartz]

fuck kinda computer are you running on

sounds like atp is gonna have to make you a rts too

[timid quartz]

@flint belfry

[spare quartz]

well im assuming since its linux its not anything too embedded...

[timid quartz]

cause this obviously isn't a normal ass pc

[flint belfry]

Three Dimensional Printer

you fucking heard me right

3d printer with a linux os

hence the no /dev/net/tun

it is network enabled just dosent have tunortap

[timid quartz]

wtf

just

get a normal ass computer that's connected to this printer

and put tailscale on that

and have that computer mediate access

@flint belfry

[flint belfry]

i dont have one nor am i going to buy one

besides i want to see what atp can do

[spare quartz]

well just fyi

lemme get the diagram

[flint belfry]

ok

[timid quartz]

👎

cringe

[spare quartz]

okay so

these are the two things you are making me do

just instead of ssh its sstp

[timid quartz]

it would be 10000% easier if you either stole some unused desktop from your school or bought a raspberry pi

or if this printer is on your home network use your desktop

work smarter not harder

[flint belfry]

0

[flint belfry]

well the client will access the server via a reverse ssh

[flint belfry]

yes i would

heres the issue

they inventory literally fucking everything

[spare quartz]

ah there you are

[flint belfry]

so its not possible

[timid quartz]

ok ask the it guy really really nicely

[flint belfry]

girl

[timid quartz]

also .

[flint belfry]

and she sucks

[flint belfry]

not

[flint belfry]

shes like

[timid quartz]

so then this printer

[flint belfry]

a jackass

[timid quartz]

is your school's printer

[flint belfry]

and not nice

[flint belfry]

yes but i have premission to do remote access

[timid quartz]

and it's being used for school things

[flint belfry]

yes

[spare quartz]

hmm

[flint belfry]

now you mkight be asking

oh dosent the printer come with in built remote access or cloud access?

[spare quartz]

so you're not allowed to use an external computer but you ARE asking me to make what is essentially a RAT for your school

[flint belfry]

oh it absoutley does

[flint belfry]

not a rat

[spare quartz]

close enough

[timid quartz]

im assuming this is for some club or class or whatever so go get the teacher in charge of this whatever group that has this printer to go to the it lady and be like "hey I need a desktop computer for this printer pls give a spare desktop computer"

[flint belfry]

ok the issue is with reverse ssh tunnels

[snow oak]

Any Luau scripters in the chat, could you explain to me how I should type check properly? I don’t think I’m doing it right.

[flint belfry]

is that every 5 to 10 mins

the ssh connection dies because the printer os is shit

also

[timid quartz]

put --!strict at the top of the script

[spare quartz]

--!strict
local alfafa: number = 2
alfafa = "4394" -- warning

[flint belfry]

i have to manually specify which ports to foward via ssh

because the software that interacts with the printer uses a ungodly ammount of them

[snow oak]

Thanks gang

[flint belfry]

im not ratting my schools network with a printer and if i was theres a much better way than this atp 💀

[timid quartz]

@flint belfry

[flint belfry]

we tried

all computers the it lady has are going to a waste center

everything thats inventoried needs to go to a location

they cant just give our class stuff

[timid quartz]

lame

[spare quartz]

     A bit map that enables (bit set to 1) or disables (bit set to 0) the use of character escapes for asynchronous links for the 32 ASCII control characters from 0x00 to 0x20. By default, character escapes are used. The ACCM bit map is set to 0x00-00-00-00 for links with XON/XOFF software flow control.

[flint belfry]

very

the inventory system on this school is really fucking tight so they watch litearlly eveything

im pretty sure they inventory computer components too

not the computer itself the fucking hard drives and ram too

thats why i asked atp to make that server so that i dont need to use the shitty raise 3d cloud interface

[timid quartz]

https://www.pishop.us/product/raspberry-pi-3-model-b-plus/?src=raspberrypi

here

buy this

[flint belfry]

(the camera updates every 30 seconds-2 minutes and also sucks ass)

[timid quartz]

problem solved

[flint belfry]

dude

i literally cant

they do routine inventory checks

[timid quartz]

get ur teacher to buy it

[flint belfry]

if that isnt authorized

[timid quartz]

or buy it yourself and put it with the printer

[flint belfry]

every po order needs to be authorized by someone for an order to be created

as well as a reason for buying said item

[timid quartz]

or buy it yourself and put it with the printer

[flint belfry]

i

was getting

to that

[timid quartz]

well there obviously is a reason

[flint belfry]

inventory checkers routinely come to check every single thing in a classroom so if they saw a suspciouis ass raspberry pi next to a 3d printer that wasnt under the schools inventory database some funky shits gonna happen

[flint belfry]

like i said we already tried

like i said the ssh tunnels work but what im asking atp to make is way simpler in this case due to the circumstances

im not ratting the damn network

[timid quartz]

idk bro

[flint belfry]

and then again

[timid quartz]

for a system like this there's always a way for a teacher to be like "hey I need this for class" and get it ordered

[flint belfry]

if you want further proof we got a openwrt glinet router to act as a way for us to interface with the printer doing exactly what im doing

then the school said we couldnt have any openwrt devices

[timid quartz]

because now you're putting some random ass software made by atp onto a printer that has access to your school's network

and atp's software may have vulnerabilities that atp doesn't know about

[spare quartz]

it doesn't

[timid quartz]

and boom your whole school network gets infiltrated because of this one printer

[flint belfry]

it dosent need to have access to the school network??

[timid quartz]

instead of getting your teacher to harass the right people and get a device that can run battle-tested software

[flint belfry]

it just needs to be able to connect to 127.0.0.1

aka the printer tiself

[flint belfry]

if it does then what is it going to do

[timid quartz]

neither ada nor rust are immune to having bugs atp

[spare quartz]

irrelevant

[flint belfry]

nobody can exploit it since it wont open any ports on the printer

not like it can

[spare quartz]

i know it doesnt because there isnt anything serious in it yet 😭

[timid quartz]

ok if theres no open ports how tf are you accessing the printer remotely

[flint belfry]

oh my fucking god

for the fifth time

reverse ssh tunnels

the printer can only handle so much so thats why the only one will be to atps server

and because you need to predefine ports with reverse ssh tunnels

[timid quartz]

and also since you WILL be accessing this remotely, this implies that your printer is connected to the internet likely through your school's network meaning that there IS an attack surface created by this printer

[flint belfry]

the printer also acceses the internet to conncet to raise 3d cloud aka the shitty cloud feature

what is your point being

the printer has been connected to the internet and network for four years now

also nobody in my school is smart enough to fucking hack

[timid quartz]

the printer pinging some api doesn't need your school to open a port for it

[flint belfry]

a printer

and why would they want to

what good

is someone hacking a printer just to have what

your describing as a rat??? i dont know

on the schools network good going to be for them

that seems like way too much fucking effort and not a real world scinerio aera

[timid quartz]

also you're operating under the assumption that your supposedly hyper-vigilant school isn't going to notice traffic over whatever reverse ssh port you use and block it on the firewall

and under the assumption that they haven't already blocked it on the firewall

[flint belfry]

ive had the reserve ssh tunnel running for 3 years

the only reason i ask atp now

is because if it drops from the multiple streams of reverse ssh then it needs to be manually restarted

there is no network monitoring at my school

theyre really good at inventory yes

but they dont give a fuck what happens on the network

and then again

why are you so concerned about this considering im not doing malicious shit

if i was doing something malicious i wouldnt be asking atp and i would have hidden something like a lan turtle in a classroom by now

[timid quartz]

cause there's just a better solution then loading some random ass code on your printer just to get remote access

[flint belfry]

ive already tried your idea if its the pi thing and it didnt work since it was oversuited for what i needed it to be so im not going to go harass my teacher go to harass the person that approves po orders to get a pi

[timid quartz]

why do you even like

need remote access

just start print jobs before you leave

or if you like realize you need to start one on the weekend then it can probably wait until Monday morning

[flint belfry]

do you know about the petg explosion

[timid quartz]

the what

[flint belfry]

and after i leave then what
the cloud platform raise 3d uses is shitty and unreliable

[flint belfry]

oh boy

hold on

[timid quartz]

….after you go home you just wait until the next morning to see if it’s done??? not like remote access would really solve a print failing mid way unless this thing can clear the bed itself

[flint belfry]

circa 2022-2023
this is why we need to be able to monitor the thing reliably

[flint belfry]

mfw seeing an issue and stopping the print

[flint belfry]

this has also permnantly damaged the printer

[timid quartz]

ok what happens if that occurs while you’re asleep

[flint belfry]

someone used wrong slicer settings and overnight the hotend jammed and spewed a shitton of petg out onto itself

[flint belfry]

i wouldnt start a massive print if i wasnt going to monitor it

[timid quartz]

sounds like an issue of people not knowing how to use the slicer correctly

[flint belfry]

well it is

but it would be nice if i could stoop it in time

[flint belfry]

also what does this have to do with what im doing

aera where the fuck is this convo supposed to go

why are you even so on top of this in the first place 😭

i literally just need atp to make software for a specific use case thats literally it

ok then

im going to go back to what i was doing

[spare quartz]

okay got PPP LCP CR done

now to send something back

[timid quartz]

Because you want to monitor this printer but invariably you can’t monitor it while you’re asleep

So either you’re not sleeping or you’re not printing when you’re gone

[flint belfry]

hold on a second

ok back

[flint belfry]

the thing is i would monitor it if its a very large print

for example

the petg explosion was meant to be a bath tub for some prop a kid needed for a science fair related project

dont remmber what it was but it took up a lot of the buiild plate

due to the shitty raise 3d cloud monitoring software we didnt have a good way to monitor it nor did i think to

so it failed halfway

i would only monitor large prints with the thing and you saying if i was asleep wouldnt probably matter

i probably wouldnt go to sleep ngl since i do that alot and my scheudle sucks but thats besides the point

its nice to have an actual good camera feed and way to control the printer and start jobs without having to deal with shitty chinese cloud software

[timid quartz]

And you’re likely to do large prints when you’re not at school

[flint belfry]

i would start then during the school day

so that if it starts failing i can catch it early

if it extends into like saturday or sunday or after school thats when i monitor it

i have used this system for 3 years now as a reminder

all im litearlly doing

is changing it to be more stable and reliable

aka the connection not shitting itself due to the 5 reverse ssh tunnels

and atps thing assuming i do get it setup we would only use it for another year

we plan to get a bambu or prusa soon the next po order since this printer has given nothing but issues

[timid quartz]

Because I’ve just thought there have been better solutions, at first I was like “why tf isn’t he using tailscale” and now I’m like “why tf does he need remote access to a printer”

[flint belfry]

well like i said tailscale dosent work on the os

and the remote access is well

[flint belfry]

i explained it from here

[spare quartz]

oh yeah um

i was meaning to ask you that

[flint belfry]

ask what

[spare quartz]

when will i be able to run a "test" of this program on that printer

cause im worried itll be all ready and yknow

not function

[flint belfry]

uhh

it depends

i have a reverse ssh tunnel to the printer i havent used in a while thats hanging on by a thread and i dont want to test your software if the tunnel drops and i cant do anything (and im on spring break)

could we maybe do it in like a week or two

since thats when i get back

[spare quartz]

sure

[flint belfry]

k

when do i send you that game

[spare quartz]

whenever you want i guess

[flint belfry]

ill do it either later or tomm

i dont have my card added on steam anyways and i need to find it

[timid quartz]

you really do have too much time on your.....paws

[spare quartz]

no ..

[timid quartz]

also atp

ur stupid language can't count

[spare quartz]

wdym

what

[timid quartz]

with Ada.Text_IO;
procedure Ada_Test is
   T : Integer := 0;
begin
   for I in 1 .. 1_000_000 loop
      T := T + I;
   end loop;
   Ada.Text_IO.Put_Line (T'Image);
end Ada_Test;

this causes a runtime overflow constraint failed exception

fn main() {
    let mut t = 0;
    for i in 1..=1_000_000 {
        t += i;
    }
    println!("{t}");
}

but this code works just fine

[spare quartz]

hold on

[lavish dove]

im so fuckin mad

[spare quartz]

your code is broken

[lavish dove]

[spare quartz]

you cannot overflow signed integers in ada

[spare quartz]

it proves our lang is safer unironically

if your lang isnt bounds checking on integers it sucks sorry not sorry

[timid quartz]

hm I see

the bounds checks are removed in rust's release profile

interesting

[spare quartz]

ohh

kinda like -gnatp (i think thats the right flag)

i think the compiler can still force checks even with it on though

[lavish dove]

[timid quartz]

our lungs do oxygen <-> carbon dioxide exchange

not nitrogen <-> carbon dioxide

[spare quartz]

okay you should've said "humans metabolize aerobically using oxygen not nitrogen"

[timid quartz]

ohhhhhhhh my goodness there you go being pedantic

[spare quartz]

ITS NOT PEDANTIC

you're just flat out wrong

[lavish dove]

how do you remember all these fucking words

[timid quartz]

that is literally being pedantic

[spare quartz]

no 😭

[spare quartz]

its biology 101

aera probably knows more computer words than i do

[lavish dove]

well yeah but I dont remember the words

[timid quartz]

"erm ackshually I'm going to completely ignore the fact that 'breathing' is used as a colloquialism to refer to the process of taking in a certain gas into your lungs for the purpose of aerobic metabolism and call you out on the fact that you did not use the hyper-specific terminology to correctly refer to the process"

that's LITERALLY being pedantic

you are literally stallman but in high school and a furry

[spare quartz]

okay but consider the fact that we are literally breathing in nitrogen all the time

[spare quartz]

ITS NOT AC actually yeah it si ☹️

[lavish dove]

omg mesa symbol

[spare quartz]

not that far away from a good connection...

[lavish dove]

woah

im still wrestling with fucking gdt

somehow the pointer or gdtr is messed up

[spare quartz]

how are you loading it

[lavish dove]

lgdt [cs:bx]

bx_dbg_read_pmode_descriptor: selector (0x0008) > GDT size limit

[spare quartz]

heres how its loaded in our tiny bootloader

i prefer using the address directly

[lavish dove]

I cant do that because its right below 4 gigs

and in real mode

😭

[spare quartz]

eehhhh

this is functionally in real mode

since no MMU is set and the lgdt instruction is called before a GDT set, making the operation 16-bits

[lavish dove]

unreal mode no way

[spare quartz]

oh nonono we're not doing any segment hacking

but our bootloader** is positioned at 0x500 just for more flexibility

[lavish dove]

yea

they shouldve like bloated everything out when they made bios

i mean like

ibm shouldve stepped up and improved legacy booting a tiny bit

[spare quartz]

ms and them tried with stuff like the bios extensions

[lavish dove]

yeah but arent those just functions

[spare quartz]

oh you edited your message oops

[lavish dove]

I changed bios to legacy boot

[spare quartz]

we're relying heavily on el torito's ability to load us at a specific segment

this bootloader can't work on a floppy

mkisofs -input-charset UTF-8 -boot-load-seg 0x0000050 -R -J -c boot/bootcat -b boot/loader -no-emul-boot -boot-load-size 4 -o bootable.iso ./fs/

[lavish dove]

el torito lets you do that??!!!

I thought it was just some mbr extensions

[spare quartz]

yeah

the default load segment is at 0x7C0 (or "0" when in iso)

[lavish dove]

woah a boot catalogue

[spare quartz]

idk what that is honestly 😭

it's just there to make the command work

[lavish dove]

it seems like just a normal table

[lavish dove]

I switched it to

mov eax, dword GDT.Pointer
lgdt [eax]```
and its the same error  😭

[spare quartz]

does GDT.Pointer have both the segment/offset next to each other

[lavish dove]

idfk
.Pointer:
dw $ - GDT - 1
dq GDT

[spare quartz]

iiii dont think you're supposed to be using a quad there

try dd for 32-bits?

[lavish dove]

64 bit gdt

https://wiki.osdev.org/Global_Descriptor_Table#GDTR

[spare quartz]

ohhh

wait

are you trying to load a GDT for 64-bits in real mode?

[lavish dove]

yeah

its supposed to be possible

[spare quartz]

then i think the instruction will still use 16/32

lemme check the manual

yeah 16/32

[lavish dove]

uhm idk what that would mean

[spare quartz]

just means a 16-bit segment selector next to a 32-bit offset

at the specified addr

(only the lower 24 bits of the offset will be used though going off that screenshot)

[lavish dove]

its like a page below the fourth gigabyte

[spare quartz]

iiiiii think you can use an operand override to let it load the full 32-bit offset

[lavish dove]

oh shit

o32

[spare quartz]

idk how that would be represented in your assembler though

[lavish dove]

I forgot about that

its o32

[spare quartz]

oh okay

[lavish dove]

fuck still doesnt work

[spare quartz]

damn

[lavish dove]

😭

whys it allways the gdt fuckin with me

when I first started I thought the gdt was paging

this is why intel wants to remove segmnets

[spare quartz]

i wonder what the gameplan for that would be honestly (along with removing real mode since thats the only reason segments still exist anyways)

do you run old apps in a virtual 8086-like mode or just dont

[lavish dove]

just dont

[lavish dove]

it would be only supported with virtual machine extensions

real mode and legacy 32 bit would be gone, only to be seen in vmx

[spare quartz]

vmx is scarry

[lavish dove]

yeah

crazy that they even thought about keeping compatibility mode tho

I mean why would they have compatibility mode

its wasted effort (only linux uses it)

[spare quartz]

shrug

[lavish dove]

I tried to use it earlier today actually but I had to install the 32 bit version of fucking everything

I guess thats just me though

[lavish dove]

man even jmp 8:0 doesnt work

[tidal silo]

how do these little shits work, ive read all the document things and it makes zero sense

need to use them for a UI

Kicking unauthorised goblins out of a room and I want a UI to pop up telling them nuh uh.

This is the script im using to do the teleporting and idk how to add the remote event stuff

then ive just got my UI in startergui

[snow oak]

I would first off recommend using :MoveTo() when moving the character.

Secondly, you can create the RemoteEvent, reference it in the script then fire it by using FireClient()

In a local script, you could set up a fire event like so:

path.to.Event.OnClientEvent:Connect(function()
 -- your code here
end)

[timid quartz]

:MoveTo() causes a character to attempt to walk to a certain point, I think a better solution to what @tidal silo is doing is using :PivotTo(). A character might not be able to walk to the exit point, and what Mildly is trying to do is teleport them, which is accomplished with :PivotTo()

-- snip
if hit.Parent:FindFirstChild("Humanoid") then
  hit.Parent:PivotTo(exit:GetPivot())
end
-- snip

Second, I'm not really sure what you're solving by recommending the use of a RemoteEvent. While Roblox's client security has increased in recent history, a malicious actor still has control over basically everything on their client. Checks of this nature need to be done on the server because we can only trust the server to do them

If you're recommending that the teleportation code be put in the LocalScript, then
a) a malicious client could edit themselves to completely sidestep teleporting
b) because the client teleported itself, due to FilteringEnabled, the client's position wouldn't actually replicate to all the other clients
If you're recommending that the client script detect the Touched events, then a malicious client could also edit that part to completely sidestep telling the server that they touched the teleport brick

[timid quartz]

The biggest issue I can see with this script is that you're re-making the zone.Touched connection for every player that joins -- you don't need to do this and you'll end up making way too many connections

What you can do is have ONE zone.Touched connection that does the rank check

so something like

-- snip
local zone = script.Parent.Zone
zone.Touched:Connect(function(hit)
  if not hit.Parent or not hit.Parent:FindFirstChild("Humanoid") then
    return
  end

  local player = game.Players:GetPlayerFromCharacter(hit.Parent)
  if player:GetRankInGroup(0) < 1 then
    -- teleport them away
  end
end)

[tidal silo]

Mmm ok I think I get it.
I was going to use a remote event to show the "you dont have access" UI for the user, is there any other way to do that then if remote events arent secure like you said?

[timid quartz]

Ahh if you're showing a UI then that's fine

Forgot about that part

Using a RemoteEvent for showing a UI is perfectly fine because the worst thing that could happen is the malicious client just ignores the GUI

But that doesn't really matter

[tidal silo]

Alr

Not entirely sure how they work 💀

[timid quartz]

Basically as that guy said

You set up a RemoteEvent object (as simple as adding a new RemoteEvent in Studio the same way you would add a Part) in a place that both the client and server could see, such as in ReplicatedStorage

Your server script is in charge of doing event:FireClient() to tell the client to do something, and your client's local script is in charge of taking that event (via event.OnClientEvent:Connect()) and then showing the GUI

https://create.roblox.com/docs/scripting/events/remote#server-client

roblox has a bunch of great docs

[tidal silo]

Yeah those are the ones I looked at

then didnt understand

[timid quartz]

What part did you not understand?

[tidal silo]

The example they added, no clue what they're trying to do and how to translate the principle to what im trying to do

[lyric mesa]

my vision was blurred and i nearly thought you started explaining the C boundary…

[timid quartz]

ngl I don't know anything about the Lua-C call boundary

[lyric mesa]

no one dares to try and comprehend it…

[tidal silo]

basically me rn

[snow oak]

Me when I spread misinformation on the internet

[snow oak]

When a player joins, the onPlayerAdded function is called. It automatically passes through the player object and is (in my opinion) a cleaner way to handle various connections.

When the player added event is connected to the function, it fires (sends the event signal) to the client. Once the event is received on the client, (the OnClientEvent block) it again connects it to a function and automatically passes the parameters through that were sent from the server.

From there, in your case, you can change your code
