15:05

@taRadvylfsriksushilani It allows you to connect multiple times from the same device

ta Radvylf srik su shilani

Yeah

Wait how many times did you connect lol

Aaroneous Miller

uh...

1?

mathcat

Don't do that innocent look at me.

It won't work

I have proof

Aaroneous Miller

@mathcat (◔◡◔)

ta Radvylf srik su shilani

No, it works. I'd quite frequently test the game by using two windows

mathcat

15:08

No, I meant the innocent look won't work

ta Radvylf srik su shilani

oh lol

@GingerIndustries use ur hacks

mathcat

Oh, righr

GingerIndustries is hecker

Aaroneous Miller

the hp bars dont seem to do anything

ta Radvylf srik su shilani

They don't yet

Aaroneous Miller

ah

is it open source?

ta Radvylf srik su shilani

15:11

Sort of, but not mostly no

I made a hack for my copy

I've been TPing all over the place lol

Bgil Midol

i joined 3 times

@taRadvylfsriksushilani whats a tping?

ta Radvylf srik su shilani

Teleporting

Bgil Midol

how???

ta Radvylf srik su shilani

It's a secret :p

mathcat

Radvylf has Paint 4D

Aaroneous Miller

2 mins ago, by ta Radvylf srik su shilani

I made a hack for my copy

mathcat

@taRadvylfsriksushilani not anymore

Bgil Midol

i want to teleport :(

@mathcat ?

mathcat

Theory: Redwolf uses Paint 4D, so traveling in 3D Space is done within seconds.

Bgil Midol

Alt theory: Redwolf uses se nitro to summon 3D and 4D, then moves through dimensions so fast in 3D and 4D it looks like teleporting, but it's just moving at the speed of light.

Aaroneous Miller

If your mouse is in front of the tank, it shoots towards it, but if your mouse is behind the tank, it shoots away from it. It's a bit wonky and a bit annoying since you'll be turning and suddenly the gun flips around

mathcat

15:18

I've already made 3 TNB theories.

PyGamer0

@mathcat 1. everyone is secretly a robot 2

Aaroneous Miller

Ok, so it looks like the point at which the gun flips around is directly related to the angle at which your gun can point, which is directly related to your reload speed

ta Radvylf srik su shilani

No, your speed

But yeah, any time your mouse is at an angle 180° to a valid turret position, it'll point there

Aaroneous Miller

setting everything to 1 gives me an angle of 90°, but changing reload to 100 gives me an angle of 180°

ta Radvylf srik su shilani

Updated to fix A+D issue

@AaroneousMiller That's because it's auto-scaling 1+1+1+1 to be 200

So your speed was being set to 50 with 1 for everything, and closer to 0 once reload is 100

Bgil Midol

15:28

if you cancel every box, you get super speed

Aaroneous Miller

@taRadvylfsriksushilani ah, so the lower the speed relative to everything else, the higher the gun angle?

ta Radvylf srik su shilani

No

It's just that the sum of the stats must be 200, so it's being helpful and auto-scaling the other stats

Aaroneous Miller

oic

ta Radvylf srik su shilani

Tryna get bullet trails to work

I'll be restarting the server a lot in the next few minutes, just a warning

Bgil Midol

@taRadvylfsriksushilani what does that do?

Aaroneous Miller

15:31

x, o, and space are no longer firing

ta Radvylf srik su shilani

@BgilMidol Disconnects you

@AaroneousMiller oops, that has to do with my hacks

Aaroneous Miller

also, you are no longer able to click and hold to keep shooting, and as long as you are holding click, the gun doesn't move

ta Radvylf srik su shilani

Fixed

Bgil Midol

no walls?

ta Radvylf srik su shilani

Okay. bullet trails are working

It triggered a client side bug, lemme fix

Okay, hard reload

You see the bullet trail twice if you shoot, but I'm working on a fix for when I restart the server next

Bgil Midol

15:36

i saw tanks, then when i shot, the tanks disappeared

ta Radvylf srik su shilani

You're on the old JS

Hard refresh should fix

Okay, I'm going to restart the server. Give me a second.

It'll fix the double trail bug

Bgil Midol

haha reload 100 go brrrr

Ginger Industries

@taRadvylfsriksushilani be careful with those

ta Radvylf srik su shilani

Okay, fixed

Ginger Industries

yo where'd the map go

Bgil Midol

15:40

@taRadvylfsriksushilani can you add chat?

Ginger Industries

hm

ta Radvylf srik su shilani

Gtg for school stuff

mathcat

Q: If I have a list and loop through it, print two slices ([n:] and [:n]), is it O(n)?

Bgil Midol

O(n^2) or O(n)

slicing is O(k) where k is slice size

mathcat

So like:

for n in l:
	print(l[n:], l[:n])

ta Radvylf srik su shilani

15:49

I set the pings to 10/s instead of 4/s as a test, if anyone wants to reload

Bgil Midol

@mathcat see my previous 2 messages

ta Radvylf srik su shilani

Do some driving around

Bgil Midol

?

mathcat

@BgilMidol didn't understand, O(n^2) or O(n)?

ta Radvylf srik su shilani

Oops, there's a bullet trail bug

That's why everyone looks like they have super crazy machine guns

mathcat

15:51

NO

Ginger Industries

hey guess what

mathcat

Don't take my machine gun away

@GingerIndustries what?

I guessed what

Ginger Industries

my tank is an enderman

ta Radvylf srik su shilani

Wait o nvm

Ginger Industries

one sec

see the tank in the middle?

Bgil Midol

15:52

@mathcat could be either, not sure

Ginger Industries

watch as it DISAPPEARS

mathcat

woah

Ginger Industries

one sec

Bgil Midol

@taRadvylfsriksushilani well, i DO have one

ta Radvylf srik su shilani

Oh lol

Yeah, there was no bug

mathcat

15:54

Eyy I can make another conspiracy theory

ta Radvylf srik su shilani

Clip hacks lol

mathcat

Vyxal Bot created Bgil Midol

Ginger Industries

@taRadvylfsriksushilani >:)

ta Radvylf srik su shilani

I have them too :p

Ginger Industries

observe as I DISAPPEAR

mathcat

15:56

@taRadvylfsriksushilani I found a bug

ta Radvylf srik su shilani

hm

mathcat

Look at that tank on the top

ta Radvylf srik su shilani

What about it

mathcat

I can move out of the canvas.

ta Radvylf srik su shilani

It's an infinite playing area

pxeger

15:58

Any final feedback?

ta Radvylf srik su shilani

You're still visible on my screen, for example

mathcat

@taRadvylfsriksushilani really?

wow

can I zoom out?

oh, ctrl - does the thing

ta Radvylf srik su shilani

Idk, I'll add it in the next client release

Noclip bullets?

Bgil Midol

what

ta Radvylf srik su shilani

I'll add HP and damage to the game during my next class

Ginger Industries

16:03

whoops I gave myself infinite reload time

campfire is the backup in case chat dies

ta Radvylf srik su shilani

16:21

Added chat

Hit t

Okay hard reload first

Just updated the JS

pxeger

github.com/pxeger/dotfiles/blob/…

Fmbalbuena

@pxeger OH

pxeger

16:49

ATO has now reached 50 non-trivial languages

Ginger Industries

fun

pxeger

@taRadvylfsriksushilani beat that!

ta Radvylf srik su shilani

Ginger. Stop spamming the tank game chat. it's not funny.

Fmbalbuena

@pxeger Wait, I don't understand

Ginger Industries

ok

I will spam no more

Fmbalbuena

16:51

@GingerIndustries no more

no more

No more

No More

Aaroneous Miller

Hit the road, Ginger, and don't you come back no more

Ginger Industries

no

Fmbalbuena

More

Aaroneous Miller

@GingerIndustries fair enough

ta Radvylf srik su shilani

@pxeger Not sure if we will

It's currently looking like RTO might not be able to exist at all

And I'm too burnt out on messing with container stuff to work on it for a little while

Ginger Industries

16:56

don't say that

I believe in you radvylf

pxeger

@taRadvylfsriksushilani oh no, how come?

(believe it or not, I support competition)

ta Radvylf srik su shilani

Well, gVisor was what we were using, but turns out it has pretty major compatiblity issues

pxeger

Shouldn't switching OCI runtimes be basically a drop-in replacement?

ta Radvylf srik su shilani

And Kata v2 doesn't support Docker, and Kata v1 hangs when you try to kill a container, and anything else is going to require weeks of rewriting stuff

pxeger

or are you doing something really funky

ta Radvylf srik su shilani

16:58

It really should, yeah, but it's harder to find compatible, sandboxed OCI runtimes than you'd think

Ginger Industries

I thought you said this was a 6 on the Fire Scale

pxeger

@taRadvylfsriksushilani runc is the original OCI runtime, which will surely be the most compatible

crun is the one I was considering for ATO, because it's fast

there's also a bwrap shim github.com/projectatomic/bwrap-oci which is pretty simple

ta Radvylf srik su shilani

@pxeger But it's not a sandbox

pxeger

it's "not a sandbox", but it's a sandbox

ta Radvylf srik su shilani

No, OCI containers without additional hardening is a very bad idea for a sandbox

pxeger

17:01

just close your eyes and pretend CVE-2022-0185 doesn't exist

ta Radvylf srik su shilani

And a lot of runtimes aren't fully compatible with, e.g., docker kill, docker stats, and docker pause

pxeger

ah

ta Radvylf srik su shilani

And I'm guessing bwrap-oci is not

pxeger

just write 500 lines of custom C and zsh code instead ;)

ta Radvylf srik su shilani

Almost wondering if some sort of nested thing would work better

Like, Docker in a full VM

Ginger Industries

17:06

sad

I have invested too much time in this frontend to give up now

ta Radvylf srik su shilani

Honestly unsandboxed docker in a VM doesn't sound like too bad of an idea, ignoring start times

It's basically guaranteed to be secure, because full VM, but also fully compatible, because full Docker

pxeger

@taRadvylfsriksushilani I mean, TIO uses literally only SELinux: github.com/TryItOnline/tryitonline/blob/…

ta Radvylf srik su shilani

RTO has a larger attack surface though, since there's not only user submitted code, but user submitted languages

pxeger

ah yeah

I think ATO's current sandbox design could securely have user submitted languages

ta Radvylf srik su shilani

17:25

I hate when I try to use curl to download a file and the result looks like this:

> <a href="https://dl.google.com/go/go1.17.7.linux-amd64.tar.gz">Found</a>.

Ginger Industries

@pxeger cmon no that's radvylf's job

pxeger

@taRadvylfsriksushilani curl not following redirects by default is indeed a bit of a design flaw IMO

@GingerIndustries I meant that if redwolf wanted to, he could copy ATO's design

Ginger Industries

o

pxeger

I'm not really interested in supporting custom languages

Ginger Industries

well I am already doing the design

ta Radvylf srik su shilani

17:27

As part of RTO's mindset of allowing anyone to keep the project up to date in my absence, I've decided to use no sandboxing at all, with all user-submitted code being run as root on my machine. That way other people can keep my system up to date if need be.

Ginger Industries

@taRadvylfsriksushilani this is a good idea that I see no problems with

ta Radvylf srik su shilani

Gonna try firecracker, what AWS uses

Today is Andrbloopitus and tomorrow is Bob

Ginger Industries

ta Radvylf srik su shilani

After that is Ksaksid, the day before Ekaksaksid, and one week before North Timothy

Ginger Industries

Oh were you not here

Ginger Industries

I was not

ta Radvylf srik su shilani

We invented a calendar system

Every day has its own name

A unique name

Ginger Industries

when did that happen

ta Radvylf srik su shilani

On Python

Ginger Industries

uh

ta Radvylf srik su shilani

17:31

The day before Jacob

Ginger Industries

cmon

better idea: give each day a random UUID

ta Radvylf srik su shilani

Jacob was yesterday

calendar.google.com/calendar/…

Feel free to suggest names for days here

Time flies, had no idea Ksaksid I was so soon

Ginger Industries

@taRadvylfsriksushilani no, today is 4fb0d7a8-8adf-5098-b630-f706669d2d54

tbh I should set up a website so you can always know the curent UUDaTID

ta Radvylf srik su shilani

Can't wait for Vapingchipmunk

Aaroneous Miller

How are we going to prevent duplicate days?

ta Radvylf srik su shilani

17:40

Beheading those who suggest them

Aaroneous Miller

that should work

Ginger Industries

my system never has duplicate days

ta Radvylf srik su shilani

Once this thing really takes off we can have a UN council in charge of naming

Ginger Industries

@taRadvylfsriksushilani you mean 4a5718ef-d8e5-50b0-a9b9-32f6b39cc21a?

ta Radvylf srik su shilani

That's unpronounceable!

Our system needs to be human readable

Ginger Industries

17:43

@taRadvylfsriksushilani it's pronounced "fourahfisiedef-dayef-fobo-aynbyn-tretugsibtrnincictwonah"

easy!

ta Radvylf srik su shilani

Not as easy as "See you on Antarctica Prime!"

ta Radvylf srik su shilani

18:15

yeah

Ginger Industries

in fact it seems you can send spaces in chat as long as you put a ZWSP in it

so that means I can do stuff like this:

ta Radvylf srik su shilani

E.g.: ‮rto.run/lg.oog

That looks roughly like a shortened goo.gl link, but it's actually at rto.run

So I can make that 301 to a rickroll

Did you spin it 713 times as it says in the instructions?

ta Radvylf srik su shilani

They actually do it for you at the factory

("713" isn't just a random model number, the "13" is the screen size and "7" is the series)

(So 311 is the really cheap one, a 513 would have a bigger screen and better specs, and a 713 is the best 13" one you can get)
