@Jupstar ✪ I was told you know a bit about this

Just look how the server browser verified symbol did it

05:09

Maybe do label overwrites it or smth like that

I did look at how the verified symbol was made. All it is is just two unicodes on top of each other.

Maybe. The verified symbol uses DoLabelStreamed, meanwhile I just used DoLabel (edited)

U can add it to the props struct with default value and remove wherever it overwrites it

@Jupstar ✪ any idea what might cause this?

It happened 4 times randomly in the last 6 months

06:51

hmm actually it may be from using nvidia overlay to record. I'm pretty sure it only happened when I did that (edited)

:\

Putting this here to remind myself later (Now that we're changing the icons, why not have there be actually different icons for the different elements?)

All of your sketches look better than anything I ever drawn (edited)

It's because it's digital

any file which aren't generated by the client cannot be accessed like that

08:28

perhaps the .map files only, but anything else needs permissions at least

isnt there literally a fuction in the code that detects what type of file it is

08:45

theres an enum AND a endswith thing

file.endswith('.map') etc.

yea

dunno what the function is called in C++ tho (edited)

eh?

if (filename[filename.lenght-1] == 'p' and filename[filename.lenght-2] == 'a' and filename[filename.lenght-3] == 'm' and filename[filename.lenght-4] == '.') {

}

LOL, is that actual code we have?

no

Should be replaced with an str_endswith if so

I hope not lol

lenght

That's just my solution

i checked, we do use endswith (fortunately)

09:19

when i get back on computer im going to try and make file_icons.png obsolete troll

(which is harder than it sounds for me)

Where are all the console commands described in the sources?

config_variables.h

09:23

i think thats what u mean right

Or rather, where the code of each rcon command is described

09:26

i need to edit super command, addweapon and jetpack (edited)

I am not an expert but maybe src/game/server/ddracecommands.cpp ?

that's exactly what I was looking for, thanks

I'm looking at the c++ codebase for the first time

I have seen multiple times an int be used instead of a bool, why is that?

Are there any sources with more server administration functionality?

09:50

It's hard for me to rewrite the code to give someone a jetpack or something else

Depends on what you do

10:34

When you have 32 bits you can store 32 booleans

well here for example IsStrokeCommand is only used there

This one is probably just an artifact of migration from C way back in the day

ok.. there are quite a few then. It doesn't matter too much I suppose, but I found it a bit confusing

Or that, didn't know tw was C only before

[ddnet/ddnet] Pull request opened: #5750 List symlinks in list_dir

This functionality was lost in 082e26d5b In my case I have a lot of symlinks in the maps folder (Downloads, ddnet-maps, map_archive) On windows, I have neither tested this behavior before nor after this patch. Could someone maybe try it out there?

i heard some funky stuff about this tho

12:01

https://stackoverflow.com/questions/30295174/what-is-the-performance-of-stdbitset

What is the performance of std::bitset?

I recently asked a question on Programmers regarding reasons to use manual bit manipulation of primitive types over std::bitset. From that discussion I have concluded that the main reason is its

12:02

sizeof(bitset<8>) => 8 sizeof(uint8_t) => 1

12:02

zero cost abstractions in c++ hehe

https://en.cppreference.com/w/cpp/utility/bitset

lol didn't know that

12:06

afterall C++ has too many stuff

yeah

12:07

but bitset doesnt optimize as well

12:07

xd

I guess that's more for simplicity ?

its cuz

oh hey

u cant use operator[] to index bits

12:07

the answer explains it

that BMTH song has a six impala remix

#off-topic ?

it's not good tho imo lol

Hm, I thought bitset did optimize properly for sizes that are = 0 (mod 8)

If you are using bitset in a way that does actually make it clearer and cleaner than bit-fiddling, like checking for one bit at a time instead of using a bit mask, then inevitably you lose all those benefits that bitwise operations provide, like being able to check to see if 64 bits are set at one time against a mask, or using FFS instructions to quickly determine which bit is set among 64-bits.

>

I'm not sure that bitset incurs a penalty to use in all ways possible (ex: using its bitwise operator&), but if you use it like a fixed-size boolean array which is pretty much the way I always see people using it, then you generally lose all those benefits described above. We unfortunately can't get that level of expressiveness of just accessing one bit at a time with operator[] and have the optimizer figure out all the bitwise manipulations and FFS and FFZ and so forth going on for us, at least not since the last time I checked (otherwise bitset would be one of my favorite structures).

Huh, doesn't std::bitset have member functions that implement these operations in an optimal way? I'm sure std::bitset::any uses an FFS

If you genuinely need to access a bunch of bits with a random access pattern which, for some reason or other, needs to check and set just one bit a time, then it might be ideally implemented for such a purpose. But my point is that almost all use cases I've encountered didn't require that, and when it's not required, the old school way involving bitwise operations tends to be significantly more efficient.

12:14

idk

hm, you can't get it to emit a clz, so finding the first set bit is annoying

12:18

but any, all, none all seem to be implemented in a sane way

12:21

I guess you could technically do to_ulong followed by a builtin_clzl

12:22

Hm, not that I could get gcc to emit a clz with a loop and an ulong

bro

17:15

it's not log4j

17:16

it's log4cpp

may be. I didn't read the documentation

Hey, which maps have the most finishes? Excluding race stuff

I very quickly went through the documentation and fashioned a few keywords: “C ++”, “API”, “Java Log4j”

lol?

there's a python program to kill your hdd as well

21:12

or kill your vps' hdd

feature idea: soft reset

21:31

soft reset will teleport you back to the last checkpoint, and it could be toggled within a map setting or tile or whatnot

21:31

cause sometimes a map doesn't work with teleport tiles so you're forced to make it faily

allow practicing players to teleport to any cp location using a custom command: /tp [number], instead of having access in rcon (edited)

Interesting information.

Practice mode really needs kill tiles to act as /r and on dummy maps make dummy's /r not teleport it to the start of the map
