louis

end character might count as 2 "slots" and run out of memory somewhere

Well, you just literally guessed the exact problem. Wanna become programmer?

huh fun

@Learath2 I made it onto the global leaderboard \o/

1

https://adventofcode.com/2020/leaderboard

@heinrich5991 congrats!

awesome :D

Wow perseverance! Congrats

heinrich pro

12:13

i wonder why there is not a single add in the leaderboard

12:14

wouldnt it be fun for a company to pay a team to get in the leader board under the name company.com/jobs xd

ad?

ye ad not add

there is a ad on the right side

12:14

but its not intrusive

no i dont mean like from aoc it self

Image attachment

but from users climbing the board to self ad

ah

or companys representing them self there

i guess u would get banned

oh rude

it’s cheaper for companies to buy ads than waste working hours on it

How i turn off the xmas skins?

@Trafalgar Law only possible server-side

12:27

or choose a skin that has no christmas version

12:28

Well, you could locally copy your skin myskin.png into santa_myskin.png

12:28

then you don't see it, but others still will

12:33

Since everyone is complaining, I'll disable events on DDNet servers :/

12:35

Oh wait, it's actually client-side. So just events 0 in console should work

@deen not everyone, ofc u will only hear ppl who come here and complain

12:41

i think russia doesnt celebrate xmas btw

they celebrate later in january

toggle event based on timezone lul

can we get ddnet to write logfiles relative to ~/.teeworlds/dumps to avoid confusion when switching from vanilla to ddnet or vice versa?

Can we get vanilla to not randomly interpret paths relative to /dumps instead?

14:36

And there were people from the companies playing AoC. A guy from spotify and github were up there for the first week but I guess none ended up in the final leaderboard

did they use spotify and github as their username tho? Or just their private name

14:54

yea its probably a weird idea to use one dood to represent a big company xd

14:54

we should try next year to get ddnet.tw in the leaderboard ;D

They had a tag next to their names

ah

They had a couple ppl playing but dont forget these ppl have full time jobs at their respective companies

14:55

Full time competitive coders are a different breed

14:56

Twilio also had one of theirs up there

so me expecting to see a company there wasnt too absurd i guess

15:05

heinrich is a different kind of breed than twilio github and spotify o.O hehe

https://www.youtube.com/watch?v=uqHjc7hlqd0 I can rly recommend this video if you want to get into bash scripting :) it is by far the most informative i found in the last years and keep returning to it to look things up

pattern match listing variables is so strong and i have never seen similar in other languages

ChillerDragon can u show an example

see i have this list of vars prefixed with acc https://github.com/DDNetPP/server/blob/23ef67af0cb5b727bcd2545618a912408f906204/lib/fddr-parse-accounts.sh#L37-L79 and ``${!acc@}`` expands to all of them. Then i iterate over them to print them all https://github.com/DDNetPP/server/blob/23ef67af0cb5b727bcd2545618a912408f906204/lib/fddr-parse-accounts.sh#L306-L312

15:28

you can also iterate over them and get the value

15:29

or you can also get the value of the variable with the name held in in a variable xd

@rqza als ob du daily uploads bis 2021 machst o.O dezember yt money iz da :D

15:37

@onbgy unmute me in #fng readonly soks

Hab meine Videos nicht monetarisiert, aber ja

Todays AOC is breaking diffie hellman, huh

@jao it's cheaper use texnonik instead 2 workers ...

I googled an algorithm for the discrete logarithm problem. Anybody did the maths themselves?

How can newbies see all srvs?

20:41

A friend can just see novice srv

clear the search bar at the bottom

That default exclude filter is very counterintuitive

@timakro no need for math today. brute force worked in reasonable time

@heinrich5991 How? Both "loop numbers" aka exponents are in the millions. I only saw the 10-thousands ticking up every second or so. The babystep-giantstep algorithm solved it in no time

21:08

I guess ~15 minutes bruteforce would be ok

my bruteforce is 10s

21:09

in unoptimized python

Send code :D

for i in count(1):
    dexp += 1
    dnum = (dnum * 7) % mod
    if dnum == door:
        break

I bet this would have overflowed for me

overflowed?

Wait I read that wrong

21:11

Theres another loop around that trying different i i suppose

no

21:11

just one loop

What

ignore the i there, it seems like I changed my idea of how this is supposed midway through

21:12

imagine it's a while True: instead

Oh

dexp = 0
dnum = 1
while True:
    dexp += 1
    dnum = (dnum * 7) % mod
    if dnum == door:
        break

It was so easy

maybe like this

21:13

what did you do? ^^

I'm genuinely am confused what problem the "babystep-giantstep" algorithm solves then

21:13

If not this

my algorithm runs in O(n)

Right, that one in O(sqrt(n))

babystep giantstep runs in O(√n)

where n is 20 million smth

ye

I wrote a function to calc the modular exponent first which had your loop inside and then called that function in a loop haha

21:16

Didn't realize you could do it simply like that ^^

ah, that's O(n²) ^^

21:17

python has modular exponentiation and inverses built-in btw

Well, that was a brainfart. But now I've got a super overkill solution https://github.com/timakro/rust-unsorted/blob/main/aoc25/src/main.rs

nice

Wdym built-in?

pow(base, exponent, mod)

uh

pow(number, -1, mod) for modular inverses (edited)

What python module is that?

without imports

21:19

just the standard pow function

Omg!

(if you use from math import * you get a different pow function!)

Good that there is math.pow without that functionality to distract from the fact that there is a better pow function built-in

anyone good with bash completion here? Or do you know a tool that has bash completion for files in a directory?

22:33

nvm got it

https://phys.org/news/2020-12-korean-artificial-sun-world-sec-long.html

Korean artificial sun sets the new world record of 20-sec-long oper...

The Korea Superconducting Tokamak Advanced Research (KSTAR), a superconducting fusion device also known as the Korean artificial sun, set the new world record as it succeeded in maintaining the high temperature plasma for 20 seconds with an ion temperature over 100 million degrees (Celsius).

23:02

POGGIES

23:03

"The technologies required for long operations of 100 million- plasma are the key to the realization of fusion energy, and the KSTAR's success in maintaining the high-temperature plasma for 20 seconds will be an important turning point in the race for securing the technologies for the long high-performance plasma operation, a critical component of a commercial nuclear fusion reactor in the future."

23:03

monkaSteerS

100 million degrees sounds spooky ngl

its held by electromagnetic force

23:11

so it doesnt touch anything

23:11

https://en.wikipedia.org/wiki/ITER

ITER (originally the International Thermonuclear Experimental Reactor) is an international nuclear fusion research and engineering megaproject, which will be the world's largest magnetic confinement plasma physics experiment. It is an experimental tokamak nuclear fusion reactor that is being built next to the Cadarache facility in Saint-Paul-lès...

23:12

if politicians didnt cut funding every year due to oil and electricity companies buying them we would have clean fusion energy already probs

23:12

https://i.imgur.com/3vYLQmm.png

maybe oil and electricity companys should buy fusion energy instead of politicians :troll:

my ddnet client freezes sometimes

23:20

and its so fucking stupid when im far on a map

why dont u freeze your client at spawn then instead of doing it far in the map?

@Iza if u got an intel, view #bugs we just talked about it

intel gpu or cpu?

gpu

nah

intel gpu lul

what else do u have then @Iza ?

who has that did they even rls yet

nvidia

chillerdragon: integrated one

ah ok fair

@Iza laptop?

yea

maybe ddnet even runs on my intel cpu

23:22

idk

yes

23:22

very probably

very probably

i'm gonna look

u can rightclikc the ddnet.exe and select the graphics processor @Iza

is that english xd?

is it not?

seems like it is

monkalaugh

sounds weird to me

23:23

i woud say "probably" or "very likley" idk

but what if its almost certain

23:23

then its very probably xd

lul

23:23

it sounds so wrong idk

tbh i also dont care, non native speakers always have the excuse to be non native speakers xd

seems like i understand "probably" too much like "maybe" and not enough like "probalistic" or something like that

23:24

sure

23:24

but i want to learn new phrases like "very probably" :D

i see it more mathematically: probability

yea

23:25

then it makes total sense

23:25

very probable

whats the ddnet exe called?

wat xd

23:25

ddnet.exe

@Iza DDNet.exe xd

or DDNet.exe

oh

if u on steam u can browse local files

23:25

then u find it

pgrep DDNet

23:25

:p

else u can also download a zip version of the client https://ddnet.tw/downloads/DDNet-15.2.4-win64.zip

[quakenet] ChillerDragon

pgrep DDNet

rg

?xd

rg > ur grep

23:27

https://github.com/BurntSushi/ripgrep

rg doesnt replace pgrep i think

Windows key -> ksysguard -> search the executable xd

Embedded image

its a emoji

23:28

hmm

23:28

true i guess

why isnt it ? or any other shit then

didnt see the p

a few days ago i found about ngrep

23:29

not network grepping :D

23:29

so there is ripgrep egrep ngrep lul

23:29

and pgrep

ripgrep is the fastest

mimimi

23:29

its not preinstalled tho

23:29

preinstalled > all

23:30

thats why bash is the best lanugage :D

nah

and microsft edge browser

23:30

:D

23:30

defaults rule

wow i was on windows 2 weaks ago, man thats annoying

23:32

it opens edge in fullscreen and annoys u

23:32

why dont we have laws against such spam xd

xd

23:34

dont we have laws against windows?

idk, but did nobody else had it after the windows update?

i remember vaguely to have heard somehwere that windows 10 is illegal

it was really aggressive

u hear lot of things

xd

23:35

regarding gdpr and data protection whatevery

23:35

win10 phoning home too much

23:35

but idk

ddnet is not detected by nvidia, how do fix that?

i dont know exactly but it has nvidia settings and there is an option for opengl applications

23:40

https://i.imgur.com/b4WHqOK.png

23:40

smth like this

but ddnet is literally not on the list

yeah u just need to set nvidia to opengl globally

23:41

like in the image the first entry

how do i do that?

well if u got the nvidia driver installed there should be an icon bottom right

Hey guys, question. If I were to do a graphics pack that needed some support from developers is there any chance that might happen? I think it would be cool if we made the graphics reflect the actual ddrace gameplay like for example having an actual frozen tee when they get frozen instead of the ninja skin and maybe a revamp of the pistol so that it looks like a pointer instead of a gun. Stuff like that.

but i cant tell if the nvidia card doesnt perform worse than the intel card

i just want my game to not freeze anymore

u can install newest intel driver @Iza

23:43

@Iza what is ur cpu name?

23:43

u can see it in the taskmanager

Image attachment

this is the driver: https://downloadmirror.intel.com/30079/a08/igfx_win10_100.9079.exe this is how to install: https://www.intel.com/content/www/us/en/support/articles/000056629/graphics.html

Solution for how to install Intel Graphi

@GoodGuyGreg we had some frozen skins already,but people didn't like it i think

@GoodGuyGreg https://github.com/teeworlds/teeworlds/issues/2173#issuecomment-508823471 Oy is on ur side :D

Client: Add tee freeze state · Issue #2173 · teeworlds/teeworlds

I would like to see support for freeze. That is for example used in DDRace and in zCatch (Anticamper). The tee can not move meanwhile. Currently they use the ninja skin for that.

@deen interesting, do you still have them?

23:52

I could just draw up some suggestions and see what the response is like.
