Can someone explain why this fails ASan? https://github.com/sjrc6/TaterClient-ddnet/tree/why_is_copyworld

Copy isn't actually copying kek

that doesn't return early idk what you mean

01:43

it does copy

the issue seems to be that CGameWorld::RemoveEntity does not check for IsValidCopy before doing pEnt->m_pParent->m_pChild = nullptr;

I consider copy should be somewhat like clone and doesn't interfere the clone and original object

01:56

Anyway you found the cause

yeah I made a new CopyWorldClean function to sidestep this

Btw I tried to teach others who want to use your client this morning (UTC+8) (edited)

01:59

But failed because they don't know where is the download folder

02:00

how did they install steam

through their ex I'd guess

<ChillerDragon> @Pioooooo oh hello fellow utc+8 enjoyer

i've seen interns graduated from CS who don't know how to operate explorer let alone terminals

I've never met one of those people somehow

Really? A friend of mine who I've been working with for 4 years now didn't know how to list a file tree under Linux, he's been a software engineer at my firm for ~6 years. But to be fair, he develops in visual studio, has never used Linux (windows exclusively) and he had his entire dev setup by someone else. I might ask him later if he knows how to add things to PATH greenthing

didn't know how to list a file tree under Linux

well i think that should be expected really...

tree isn’t even installed by default on many distros

not knowing how to use an OS you never use and not knowing how to use the OS you use every day are completely different things.

06:41

the important part is also not even having anything memorized, if someone tells you "find the file in your download folder" and you can't do it even with google then you're pretty clueless.

i still remember the days where people freaks out because "My Computer" is no longer visible on the desktop.

that was annoying to get used to

I don't remember what My Computer did

before they put everything into a single file explorer there was My Computer and Network Neighborhood iirc. so just two file explorers one for local one for remote

We were talking about software developers btw. Ofc it won’t matter if my accountant doesn’t know what a terminal is

i don't like midlife crisis dad greenthing

TsFreddie

i don't like midlife crisis dad greenthing

i've noticed a pattern recently, as soon as my dad sees me coding he will stare at my screen pretend to know what im doing and when i ask does he need anything he'll just say "doesn't look too complicated, i can do this too if i try, i just don't feel like it"

08:05

it's like talking to teenage boy with too much self-esteem justatest

doesn't look too complicated, i can do this too if i try

basically me about any new project idea xd

xd

somebody help, why command dbg_dummies dont work???

it only works if you build the server yourself with debug mode, and the sever dummies won't do anything, they are for debugging.

Learath2

I had a friend defend this situation to me, trying to convince me that someone who doesn’t know what a terminal is can be a good hire

there are probably hundreds of web developers making 6 figures who never use a terminal at their job even once. So I don't think he is really wrong.

TsFreddie

and how do I enable debugging mode on my server?

Tater

not even npm run dev ¿

08:10

alright true

08:10

idk how you avoid it xd

well you can if you only develop static html or js only frontend with plain js and you test it with double clicking the html and use a cors bypass extension

or you have a hotkey that launches your project

08:12

that someone else setup for you

even then vscode just opens up a terminal when you do that i think? so at least they've SEEN one

08:13

or they are just using devin

08:13

devin is here to save web dev

I guess to be a good web developer you also must know about the browser javascript console

Tater

or you have a hotkey that launches your project

mod4+shift+lctrl+kp_5 to launch ddnet in vsc greenthing

why so many buttons justatest

08:14

every function key is taken?

melon be using 25% keyboard

Every keybind that launches something is bound to at least 2 modifier keys, I have fat fingers

how fat your finger is that you could just hit a f5 that far up above

I died mid run 3 days ago because I accidentally launched Firefox while playing, Firefox is Ctrl+shift+alt+f AquaTriggered

can someone explain the appeal of using a low% keyboard as a developer. I thought the whole point of the small keyboards was to get extra desk space for your mouse to be closer to your left hand.

save hand movement actually

Are you a left hand mouse user???

no

cuts down a lot of reaching and finger extensions

TsFreddie

save hand movement actually

but the buttons aren't more dense?

ye but i don't need to reach for function rows or numbers

"save hand movement" -> "press 4 keys to launch your project instead of 1"

08:17

nice

hand movment, not finger strength

These minimalistic keyboards are annoying to me personally, it's rare but I do need a keypad and f1-f12 keys, and I don't want to press something like fn+1 to actually press f1

08:17

I use a 100% keyboard

like saves your arms and wrist

how do I enable debugging mode on my server?

TsFreddie

like saves your arms and wrist

Get a split keyboard boom

TsFreddie

the only reason why i tolerate modifiers is that i have split space bar

08:19

a lot of stuff is right space modified

ew

maximum ergonomic

tie fighter build

i do need numpad and stuff occastionally to be fair. but i have those on my laptop keepboard

function row is usually not useful for me

08:21

but i like my arrow keys

my arrow is just right space + hjkl

08:22

still one hand, home row and thumb, imo pretty easy to get used to

maybe the small keyboard appeals to the minimalist OS user, "I don't press those buttons so I should remove them"

ive historically had a lot of issues when i try to use arrow keys + some other key on top of it

heck i don't even have capslock, my capslock is backspace

the modifier will not recognize i only want to modify the arrow keys

Tater

maybe the small keyboard appeals to the minimalist OS user, "I don't press those buttons so I should remove them"

you mean the 6 key block + numpad?

idk

08:23

any keys

oh i forgot to order a anykey keycap

i understand 60% for developers but nowhere under that

thanks for the reminder

08:25

i use 60% now just so i can play deadlock

08:25

but i did use 40% most of the time in college

i can still find my 40% layout even tho i don't have that keyboard anymore

08:28

i made that warning, it's my tool. it's fine I tested it

o lol

08:31

they should add more memory if the keyboard is missing so many keys

it's probably not a memory thing

08:32

just terrible firmware in general

08:32

the firmware is so bad they stopped updating the version that supports custom layout lol

No but the correct way to scream is to always use the opposite shift key to the key you're pressing

too bad chinese doesn't have uppercase

Unless you're one of those filthy people who doesn't know how to use right shift

11:06

You guys should invent lowercase Chinese

its called simplified chinese

No but the correct way to scream is to always use the opposite shift key to the key you're pressing

And this is slow and annoying

I've never used right shift in my life

Hey, I received a complaint from my hosting provider about port scanning activities originating from my DDNet server. The complaint mentions multiple UDP connections on port 8307 targeting external IPs, all of them are Hetzner's subnets. At the time of the incident, logs show users on the server were complaining about lags and high ping. Could this behavior be related to the server configuration or a known issue with DDNet?

11:10

I mean, it for sure looks like a DDoS-attack, but how did the perpetrator manage to make my server echo another IP, since none of the IPs were related to users connected at the time.

11:10

The outgoing traffic was exceeding 8 Mbps. For an hour.

11:11

While the incoming traffic was at about 1 Mbps.

I hope DDNet master-server or any other infrastructure don’t use Hetzner subnets, as of now I’m disallowing any traffic on DDNet-Server ports on Hetzner’s subnets.

Seems like someone is using spoofed IPs to make you reflect an attack against our official DDNet servers (and other servers at Hetzner probably)

11:35

See these iptable rules to prevent your server from responding to all incoming requests: https://github.com/ddnet/ddnet-scripts/blob/master/ddnet-setup.sh#L45-L55

Already on it, implementing DNSBL and will look into iptables rules. Any of your servers use Hetzner?

someone did the same two months ago too, happened to me too

Yes, many: https://github.com/ddnet/ddnet-web/blob/master/www/_includes/funding.html

deen

Yes, many: https://github.com/ddnet/ddnet-web/blob/master/www/_includes/funding.html

I see. Is enabling DNSBL in server config sufficient or do I need to further configure the VPS? I cannot run the script since VPS is hosting many other projects, I will selectively implement some parts of the script. As for DNSBL, I cannot tell if any additional configuration is needed besides sv_dnsbl* cmds.

Network monitoring logs.

ok, bcs i also had that once (for tcp traffic) and disabled all tcp traffic and they still claimed that my server created so much traffic. so i wrote the support to monitor my server and since then they never banned me again xd

12:05

tho it's not hetzner

My thing was real, only UDP, only DDNet-Server port. Backed up by logs.

what you should defs do is ignore any inc packets from client port <= 1024

12:08

that already solves most port scanning reports

It says that my server was port-scanning Hetzner’s servers. I have UFW enabled, so only needed ports are allowed. This is a DDNet-Server-level issue. (edited)

Thanks for the heads up. I was gonna get myself into a heated discussion.

his server did port scanning bcs it responded to spoofed ip packets
