is that the expected result?

its blinking rapidly

10:43

and only blue rectangle stays

do u clean correctly

thats how it looks if i run with intel

do u have the source available

of my program?

10:45

i think its driver problems justatest

well if u doing something wrong it can show diferently

10:52

idk

i just have one big cpp file xd (edited)

4.78 KB

message.txt? XD

Yea

11:14

I dont have it on gh but i can send it as zip if needed :/

11:19

i hope it works justatest

Click to see attachment 🖼️

did you animate this? oO

mocap

11:48

with that mocopi thing

11:49

and yes, it was me

11:51

that looks pretty well animated

11:51

the second video, too

it's just the default app that comes with the hardware (edited)

ahh

11:53

it's a rendering of your movements? it's not you who animated this character

no. it was motion capture

ah. forget what I said

11:53

still neat, but I thought you made this character

11:53

i wish

can u put custom characters doe

I can

11:58

I don't have any tho

gotta make a tee

11:59

no idea how you would rig a tee

Take man model and replace head with tee (edited)

that would still be a man with a tee head

that's very cool

12:57

I think someone wrote a bootstrap starting from a JS interpreter recently

12:58

was on the "bootstrappable" mailing list

13:00

Even more recently (2018), the GNU C Library glibc-2.28 adds Python as a build requirement,

13:00

oof

Some time ago, Wladimir van der Laan contributed initial RISC-V support for Mes but a major obstacle for the RISC-V bootstrap is that the “vintage” GCC-2.95.3 that was such a helpful stepping stone does not support RISC-V. Worse, the RISC-V port of GCC was introduced only in GCC 7.5.0—a version that requires C++ and cannot be bootstrapped!

(edited)

llvm also needs python

Repeek Ethami is being not ddosed but spammed with clients :(

14:12

Any idea how to counter it? I banned some versions but they still appeared as (connecting...)

who is Repeek Ethami?

Mr.Gh0s7

Repeek Ethami is being not ddosed but spammed with clients :(

have you tried banning the IPs they're connecting from?

i guess a mod

heinrich5991

who is Repeek Ethami?

It was I.

heinrich5991

have you tried banning the IPs they're connecting from?

they're too many tbh prob proxies or smt

14:16

like 4 players and 60 clients/proxies

you saw 60 different IP addresses?

58

14:19

I can dm them if you want

MilkeeyCat

ehm, ive tried to run my program with gpu justatest

ok maybe someone just accidentally deleted glClear(GL_COLOR_BUFFER_BIT) line owo

ah forgot to remove the port sec

14:21

ok now the file with the ips is 58 lines long and 40 of them are unique (sort file | uniq | wc -l)

interested in DM

Mr.Gh0s7

58

Maybe you had 6 players? IIRC I seen more addresses (tried to ban but it didn't work because new clients used new IPs). At that time I had captcha on the server (unique per-IP password added to the server name), it helped. Unfortunately I had to drop captcha support to sync with DDNet server info cache implementation.

see i was right!

Ryozuki

see i was right!

yes you were owo

NOW I HAVE A RECTANGLE

14:24

HELL YEAH

pog

14:24

make it rotate and go up and down in a sin wave

14:24

also change its color using that

idk how to record a vid of it xD

Yeah I had 6 Players. Tha'ts correct. So it filled everything with proxies 40 of them where unique

entering your IP addresses into a random proxy checker raises all alarm bells ^^

perhaps you could do some automatic bans based on that?

big zero day

guys guys, is nixos good?? or just nix??? or just what do you think about it? the tool looks very promising

whats nix/nixos?

https://nixos.org/ ¯\_(ツ)_/¯

Learath2

Like hardware fault injection (glitching) or in the more general systems sense of it? I was curious about the former but not something I ever really explored beyond idle research

yup, clock & voltage glitch, em injection

17:24

but low pay as intern, 550€

its nice but becomes tiresome rly fast

How do people live with that wage even? Is it part time?

Robyt3

[ddnet/ddnet] Issue closed: #7329 Switching freeze stars and slider

Learath2

How do people live with that wage even? Is it part time?

In France an internship last at most 6 months and is paid roughly 600EUR (minimum but also very common) if it lasts more than two months. The maximum work time during internships is 35hrs/week.

17:41

student precarity is a thing like everywhere, but also we don't pay public schools/uni so there's that

17:42

and there's social security

So that's 7 hours a day, a standard work day, how are the interns supposed to earn the extra 1000~ euro needed to get to the living wage?

I was able to live with that for a while, but when you go to school you don't get paid at all so idk it's already something

k2d222

and there's social security

xd like in any eu country

17:47

doesnt justify the slavery that this is (edited)

how is it elsewhere in eu?

its sad working people tend to accept the shit they give em

17:47

i mean that mentioning social security and public schools is a given in eu

17:48

in spain its prob the same for internships, cant say since i didnt do any

17:48

i got myself into the real market asap

k2d222

I was able to live with that for a while, but when you go to school you don't get paid at all so idk it's already something

u lived with ur parents right

17:48

if u live in paris, im sure rent is higher than 600€

17:49

my first job was part time

17:49

i worked 20h a week

17:49

i got like 550€

Ryozuki

u lived with ur parents right

nope in a shitty bedroom I paid 250€/month, not in paris ofc

when i was searching for a apartment in barcelona i looked at prices for bedrooms

17:50

they go easily to 800€ too XD

17:50

but i got myself a apartment for 800€

17:51

internships are just wage abuse

17:51

(i get 2100 now)

I agree that in big cities its impossible to live with that, and I also agree that it's unfair btw

learath knows too much to be taken advantage of like that

17:52

he probs just lacks xp on how to deal with other devs in a company or smth

17:52

but skill wise more than done xd

Ryozuki

he probs just lacks xp on how to deal with other devs in a company or smth

(altho i guess this is mostly common sense)

17:54

@Jupstar ✪ r u alive, havent seen u since a lot

k2d222

I was able to live with that for a while, but when you go to school you don't get paid at all so idk it's already something

Well where I'm from a lot of students are just dependent on their family, I'm guessing that's the case most anywhere else

Ryozuki

learath knows too much to be taken advantage of like that

The only reason I'd be okay with getting paid below poverty wage would be if I were really curious

@k2d222 are u a dev? what langs u use btw

Ryozuki

idk i doubt internships are fun

Fault injection does sound very intrihuing

I have been curious about it since the infamous nintendo switch jailbreak

Ryozuki

I graduated in september

I do web dev c++ and some rust mostly

oh nice

17:59

more rust more rust

Replace the c++ with rust and ryo will like you

for any new project rust is the go-to

my web dev stack is rust for backend with axum + sqlx + postgres and frontend with sveltekit + tailwindcss

18:00

if u want a nice local cache in rust, i recommend mocha

@Ryozuki I've been thinking of doing a rewrite of ddnet

ok not mocha its moka

rust is soon a decade

18:04

1.0 was released in 2015 iirc

18:04

so 2025

I wish I paid more attention to rust in 2015

same

I could have been one of the cool people that know everything about it

like heinrich

18:05

his secret persona is a contributor iirc

18:05

i have a coworker who is inside the rust-lang github org

18:05

used to contrib docs

18:06

matricks is also an og rust contributor iirc

internship is not the same as job

fancy words

Ryozuki

if u live in paris, im sure rent is higher than 600€

as a student, you can get CROUS residence where rent is around 300€ to 600€ depending on the type of room

Chairn

good luck finding a crous in paris though

i had a room with 392€ rent

18:09

11m² with everything included

Chairn

internship is not the same as job

Surely but interns are also human and have all the same expenses as the other humans, no?

18:34

Like if housing or food was free for interns I could justify paying them much less

Learath2

Surely but interns are also human and have all the same expenses as the other humans, no?

with the same argument, students should be paid to go to uni, do you believe that should be the case?

Ryozuki

btw my wasm experiments https://github.com/edg-l/wasm-stuff

tell me about them

k2d222

with the same argument, students should be paid to go to uni, do you believe that should be the case?

you can get a generous student loan in germany when your parents aren't rich

18:38

I think you only have to pay back half

k2d222

with the same argument, students should be paid to go to uni, do you believe that should be the case?

School doesnt have to be a full time commitment, and most civilized countries do already help atleast a bit (tax benefits, student pricing, great loans, even some living expenses in the nordics). But sure in an ideal world I don't see any harm in supporting students through their education.

Learath2

Surely but interns are also human and have all the same expenses as the other humans, no?

i agree, but i cant change law and how public service works

#[repr(C, packed)] should probably not be packed (in interface/src/lib.rs)

@heinrich5991 isnt it unsafe if u have padded bytes

19:32

i forgot

idk what you're doing but that would only be the case if you are de/serializing structs as a whole

19:33

which is unsafe in other ways

reading uninit bytes in rust is ub

k

@Ewan its said holding guarantees in unsafe rust is harder than c++

19:40

but idk

19:41

https://users.rust-lang.org/t/is-it-ub-to-std-copy-padding-bytes/75993/4

Is it UB to std::ptr::copy padding bytes?

There's actually nothing special about "padding" bytes; they're the same as all uninitialized bytes. (You can also get uninitialized bytes by, say, looking at uninitialized parts of a Vec's buffer.) The problem is not about the reading specifically, but into which type you read it. Remember to look at the whole bullet: an integer ( i* / u* ...

it's more unsafe if you have repr(packed)

[ddnet/ddnet] Issue opened: #7331 multispec

addnew value where u can set minimal zoom. i play on 6 zoom and my eye cry when mutispec zoome like 10. some one can say "u can zoom out in multi"

yes i can, but if they have so much space betwen each other it is too small.

so i think new value will fix that.
