d0b31d6 Add curl_slist_free_all to the list of required functions - heinrich5991

have you ever had a computer that shuts down just like there was a power cut?

01:17

my old thinkpad just did that, and it's not the first time

01:18

all kernel logs show nothing, except sometimes the last line before reboot is truncated and filled with null bytes

01:18

time to save my work on usb stick

perhaps the hardware powered down because it was overheating

nah, laptop is cold, and overheating would have a trace in kernel logs

01:47

i was just typesetting some latex, nothing fancy

why would overheating turn up in kernel logs?

01:48

isn't that mostly hardware stuff?

i suppose there might be a shortcut because it happend when i layed down my hands on the keyboard quite fast

01:48

nah, it triggers an interrupt first

01:49

when the interrupt is fired, the kernel has like 15ms before going down

oh

01:49

TIL

at least, it's the case in most embedded cpu i worked on

01:50

temperature cinetic allows this stuff

01:55

this is final message in /var/log/kern.log:

May  3 03:08:30 hostname kernel: [36837.329504] [UFW BLOCK] IN=enp0s25 OUT= MAC=12:34:56:78:9a:bc:de:f0:12:34:56:78:9a:bc SRC=192.168.1.1 DST=224.0.0.1 LEN=32 TOS=0x00 PREC=0x80 TTL=1 ID=0 DF PROTO=2

Chairn

nah, it triggers an interrupt first

there's also an interrupt when power goes down

02:14

first there's brown out interrupt

02:15

then there's black out interrupt

02:15

black out interrupt typically state, cpu can execute x instructions (not guarenteed) (edited)

bra Ac1dBeef stap reconnecting :/

does anyone know if using references within functions has disadvantages? https://www.tutorialspoint.com/cplusplus/cpp_references.htm E.g. if I do something like vec2 &ViewPos = pGameServer->m_apPlayers[SnappingClient]->m_ViewPos; so I don't have to write the long expression repeatedly? Is it better to use a reference than a pointer?

C++ References, A reference variable is an alias, that is, another name for an already existing variable. Once a reference is initialized with a variable, either the variable n

use a macro :trol:

08:29

i think jupstar once said that refrences are the better pointers

deen

no, server doesn't know the difference between another player and dummy

Could be just fixed by one vote per IP to use practice

ddnet/2021-09-15.log:38:12:01 <+bridge> [ddnet] <Jupstar ✪> reference is bascially same as pointer, just without uglyness and NULL xd

if anything you can actually gain (at least on msvc) from using a reference/pointer instead of writing long chains everywhere (edited)

omagwad im too stopid to write collision code -.- send brain

i think its better to use the reference

this guy

11:37

I think i need a better irc client or filter out connection messages in weechat -.-

/set irc.look.smart_filter on
/filter add irc_smart * irc_smart_filter *

Smart IRC join/part/quit message filter - WeeChat dev news

A new smart filter for IRC join/part/quit message has been added. It is disabled by default (so you'll see all join/part/quit by default). To enable it, use following commands:

ye i also did that but then i realized i wanna see those messages

11:58

but this guy is literally flooding it -.-

bad collision code? or awesome walljump feature? :D

Ac1dBeef:!

while revising and testing the dragger.cpp I noticed that two different ranges are used in the old code. First the characters nearby are selected here: https://github.com/ddnet/ddnet/blob/14927684eb078615c7eab8841c7043e0d063d6b3/src/game/server/entities/dragger.cpp#L59 Here the range g_Config.m_SvDraggerRange is used but in the function FindEntities https://github.com/ddnet/ddnet/blob/14927684eb078615c7eab8841c7043e0d063d6b3/src/game/server/gameworld.cpp#L56 the m_ProximityRadius = 28 of a char is added. And later in the code the tee is droped (so not pulled) because of this line, because the m_ProximityRadius was not added: https://github.com/ddnet/ddnet/blob/14927684eb078615c7eab8841c7043e0d063d6b3/src/game/server/entities/dragger.cpp#L138 Should I also ignore the m_ProximityRadius in the new dragger? I do not think any map would suffer if we would add m_ProximityRadius but it is a physics change

This would basically increases the range of a dragger by ~half a tee (edited)

If someone wants to give his opinion on this please tag me or write it on the PR https://github.com/ddnet/ddnet/pull/5063 so I can read it later....

when i have problem with lag, someone let me download 16.0-rc1 beta with vulkan, but now i don't receive new update, what i need to do :d

download the latest client

13:59

from the web

13:59

it has vulkan too

13:59

and better

one thing i noticed is lot of ppl force push on pull requests, but specially on large prs this makes revieweing harder

14:02

because you don't have a diff from your last review

14:02

so u gotta check all over again

14:02

imho i would rebase when its finally reviewed into a clean commit

Ryozuki

imho i would rebase when its finally reviewed into a clean commit

xD do you mean me?

xd in general

14:14

but in this case i said this cuz i noticed heinrich

14:14

force pushed the master server pr

I think he published it as draft just that we can have a sneek preview... Was not ready for review

ah

14:16

ok xd

A question about prediction. Other players hooks are predicted? What if a tee near you is hooking another tee out of camera? Is prediction broken? Or is hook predicted with destination point too?

the prediction needs the hooked character, so if the hooked character is network clipped the hook won't get predicted
