I released TwMap v0.8.0: https://gitlab.com/Patiga/twmap/-/releases/v0.8.0

11:01

License change to AGPL 3, lots of changes (sadly also breaking), support for automappers

11:01

listed all changes in the link above

Nice!

11:03

because of the many changes, I hope I don't have to do a breaking fix soon because I missed something major

Mutexes rly should contain inside the data they guard

11:19

Its such a waste of time to figure out what they guard

11:19

And the names dont help

LoopL xd

@Ryozuki LoopL is only the the lock guard, I think

@gerdoe forgot to ping you for twmap release ^^

@Ryozuki is it public btw?

heinrich5991

@Ryozuki LoopL is only the the lock guard, I think

Yes. There is one lock guarding everything that is cross thread inside CHttpRunner. Multiple unique_locks to make sure things get unlocked properly on unexpected early exits from blocks

heinrich5991

@Ryozuki is it public btw?

Not right now

14:10

But idk if i wanna share that here

14:11

I only just started so there isnt anything tangible yet anyway

14:14

For the frontend ill use sveltekit

14:15

Cant get any more modern

@Learath2 lmao found this on discord gifs "anime programming"

Lol so true

Lol so true

I saw a funny thread on hn the other day

14:50

A c user on a rust related news, posted his project and said "find any memory related bugs" you wont find any

14:51

Dont need to say he got rekt

14:51

(his project was in C)

14:51

But he started putting excuses

14:51

On the bugs

14:51

It rly was funny

I would have never gotten rekted as he was. I'm built different

BASED

Ryozuki

But he started putting excuses

Like what? How do you even excuse a buffer overrun?

He also blamed some stuff on libraries etc

14:52

And some commits where literally saying "fix double free"

I hope people didn't "rekt" him about things that are runtime constrained, calling an internal function with impossible values isn't fair criticism as long as he never calls them like such

And he said, yeah thats because it was before "production"

14:53

Anyway its also fun to see r/cpp

14:54

You can rly see how close minded those ppl are

Ryozuki

And some commits where literally saying "fix double free"

Ok, now I'm on his side, wtf

They drive high on copium about ppl not using modern cpp

The language this guy uses doesn't remove the possibility of memory management errors, ofc he had to fix mistakes. Don't rust users make any mistakes on classes of mistakes possible in their language?

The thing is you cant make that mistake in rust

I know, that's why I said in the class of mistakes possible in their language

14:56

If a mistake is made and fixed, what is the issue?

There are proba more mistakes like that because they cant exist

14:56

In rust you cant have them at all

14:56

Thats the thinf

14:56

Thing

14:57

Cant you rly not see how good that is?

So the mere possibility of mistakes implies all C programs are wrong? Even if mistakes are fixed before the program ever hits production?

You said that

14:58

I just said it means there can always be more mistakes

14:58

And cve lists shows its real

14:58

Also it gives other devs more security

14:58

E.g your pr

14:58

I would be more confident about it being right if it was rust

14:59

I would only need to look for deadlocks

I don't quite get how a fixed mistake is an own. Sorry

15:00

Doesnt mean I don't understand the value of Rust's memory guarantees. I just don't get how one person making and catching a mistake they made has anything wrong with it

Not having the possibility to ever have that mistake > being possible to have the mistake

15:00

Its rly simple

15:01

@Learath2 cuz the guy on the thread dismissed everything about rust

Ryozuki

Its rly simple

It actually isn't that simple and that's why you use Rust instead of languages with much stricter guarantees

15:04

Ada has guarantees about deadlocks not existing, bounds checking, contracts, at the cost of performance. Haskell is provable at the cost of ergonomics.

15:04

These are general purpose languages. There are DSLs with even stricter guarantees that only allow you to do a very specific subset of things

15:05

Rust is just a great compromise. It trades off some ergonomics for memory safety

15:07

I honestly don't get these religious wars about programming languages. Most all of them have a place

C has no place anymore, outside niche compile targets

15:07

BASED

15:07

And when gcc lands not even that

15:07

BASED

how to trigger learath 2.0

This is why people dont really enjoy rust evangelists

15:08

What do you gain by "triggering" me? Ok gj, you annoyed me. What is tbe next step?

Im triggering u on purpose

15:08

xd

Do you think I'd be more or less open to Rust after you "trigger" me?

oh god

15:09

Cant even joke

15:09

I thought we were on the same page

15:09

But i guess not

15:09

Sry if i offended you (edited)

i love how learath has to use quotation marks

Ryozuki

Sry if i offended you (edited)

No I personally don't care. You can joke all you want. But a lot of the people that have been trying to sell me rust in the past have actually went that route

I dont talk to any c devs outside this channel like this

15:11

Cuz i know im a rust meme here

Anyway, the place of C in the current era is the universal interface. Since no one is going t get together to make a proper ffi, it'll just stay like that for a decade or two

Yeah

15:12

C is not a language

15:12

But a protocol

15:12

You are forced to speak

Honestly I've had a better time talking C even between rust code and rust code

hm?

15:14

I dont get what you mean

The complexities of modern languages don't deal well with how simple the underlying hardware is. It sends around bytes, it doesn't understand what a std::HashMap is

[ddnet/ddnet] Issue closed: #5628 Compilation from the AUR fails because of -fcolor-diagnostics

Ryozuki

I dont get what you mean

I mean I've had a better time exposing rust functionality through the ffi and consuming it through the ffi then trying to link together a rust binary and a rust library

15:15

Specifically when one was compiled with a different version of rust. There are some breaking changes you need to keep track of to do it properly

15:16

Even more specifically I was working on a plugin system of sorts

Ah probs

15:17

Did u do repr c

15:17

The struct layout is not guaranteed otherwise

15:17

Rust optimizes it

Yes, on the outside facing interface I did

Have u considered using wasm for that

15:18

Wasntime just got 1.0

15:18

Its a wasm runtime made in rust

That's what I'll be doing next time around. I honestly am just tired of dealing with plugins in native code

And they are sandboxed

15:19

A plus

I like lua, I like wasm. One of those would be what I go with next time around

https://news.ycombinator.com/item?id=32913533

ridruejo

15:19

wasm is better

15:19

you dont bind the person to a language

Or maybe I'll take a look at js. V8 isn't half bad performance wise either

i personally dont like lua

15:20

why

15:20

just use wasm

Ryozuki

https://news.ycombinator.com/item?id=32913533

i read this as "wasntme" like the map

Ryozuki

you dont bind the person to a language

I actually kinda like there being a language pre-agreed on

why? xd

15:21

i personally want to find a language with modding where u can use rust

15:21

lua is so boring

15:21

s / language / game

15:21

oof

You write stuff. My code runs the stuff. When there is a compiler inbetween that's one more part that might be introducing an error

Voxel

i read this as "wasntme" like the map

I read it as wastetime 1.0 xD

Ryozuki

why? xd

Idk proba

15:23

Kek

15:24

Im sure i posted that image

15:24

Oh wait

15:24

Is this another sv

llvm can indeed target wasm

thing is heinrich is adding rust into the ddnet client; im really curious as to what rust updates to the game will be like besides memory management

Wdym by updates

15:29

I would have done this http multi in rust

15:30

But its hard to interweave the code probs

15:30

Idk how worth is adding rust here

It would actually be a good place to use rust

16:52

It's a totally separate module

Yeah

17:08

But poc is not merged

i wish it would motivate the rust devs around here, but probs not, except maybe heinrich himself

I only need to fix the damn macos

17:15

but I guess I need access to a macos machine for that

17:16

I need rust to produce a fat binary for the library

17:16

but that's not really supported, so I need to hack my way around that

Maybe you can ssh to my laptop and poke around at it?

if you'd allow me to do that, I'd be very interested

17:17

another bug I'm currently facing:

17:18

the https register connects via IPv6 (or at least re-uses IPv6 connections wherever they came from) even though it explicitly requests CURL_IPRESOLVE_IPV4

17:18

I stepped through it in the debugger to see that it really sets CURL_IPRESOLVE_IPV4

17:19

and I quickly looked at the documentation, it seems to indicate that CURL_IPRESOLVE_IPV4 will only attempt IPv4 connections. comments in the curl source code suggest, that this also applies for reusing connections

17:25

aha!

[ddnet/ddnet] Issue opened: #5858 HTTP register uses wrong IP version on old versions of libcurl (<7.77.0)

This was fixed in https://github.com/curl/curl/commit/84d2839740ca78041ac7419d9aaeac55c1e1c729, but our servers run curl 7.74.0.

Jupstar ✪

i wish it would motivate the rust devs around here, but probs not, except maybe heinrich himself

i mean there arent many rust devs here

17:55

i only know heinrich patiga me

17:55

and learath ocasionally

17:55

actually thats probs close to 30-40% of total devs xd

Ryozuki

i only know heinrich patiga me

reitw too

theorically im getting the steam deck tomorrow

then change it, coding is best, coding is creation. if you aren't a craftsmen then there is almost no alternative to coding to create useful stuff

wait @heinrich5991 are you saying rust is not added into ddnet because of https://github.com/rust-lang/cargo/issues/8875 ?

19:40

for me it looks more like a nice to have than a actual blocker

I'm saying that a workaround for that bug needs to be found before rust can be added to ddnet, yes

but didnt the dude provide the workaround in the issue desc?

macos needs binaries to be compiled for amd64 and aarch64

doesnt it compile for both arch by default?

19:44

and then its running the lipo command

rust? no, see that bug

i mean mac

19:44

and for rust you can specify

yes

19:44

so you need to integrate that into cmakelists.txt

19:44

that hasn't happened yet

ye

19:44

a

19:45

yea i assume without testing thats pain

19:45

What about cross compile?

19:45

thats almost more important isnt it?

I haven't attempted to cross-compile to macos

is there even a lipo command for linux?

currently it's more important to compile on macos, that's how releases get built currently

19:46

yes, definitely

wait wot?

19:46

releases are build on mac?

19:46

ah wait since deen switched i guess? :D

yes, since code signing of fat binaries did not work under linux

macos moment

19:48

the only time i heard of code signing and fat binaries is while reading this book :D https://nostarch.com/art-mac-malware

The Art of Mac Malware

A handbook for Apple infection methods, malicious script analysis, and Mach-O malware.

19:48

i rly got disconnected to mac

19:48

not sure if i can recommend the book tho. Its okay.

[ddnet/ddnet] Pull request opened: #5859 Only start registering once the server is fully started

This works around, i.e. fixes #5858 for curl versions < 7.77.0, as long as the servers are only registered via IPv4 OR IPv6. The bug that's being worked around is this: https://github.com/curl/curl/commit/84d2839740ca78041ac7419d9aaeac55c1e1c729. The bug makes curl reuse IPv6 connections when it is being requested to connect via IPv4, making the registering fail. This commit works around that by letting the server only register after having completely read the config, so any `s...

[ddnet/ddnet] Issue opened: #5860 EntityEx, moving more info to extended netobjects

Since netobjects are easier to extend now, and since EntityEx still has its issues/limitations, it can perhaps be considered to move the info from entityex (i.e. switch number) to DDNetLaser, DDNetProjectile, and so on. Some thoughts/proposals:

Adding the switch number to DDNetLaser. It would also be nice to distinguish both between all the laser types (this is already added in ddnetlaser, but only for the door type), and to add a "SubType" field to further distinguish for example types...
