Default avatar.png BlueSamourai_aaf5: RANDOM HI

eulerscheZahl: https://www.lux-ai.org/specs-2021 it has started

jad-debugs: hello

Default avatar.png Coding_GameGuy2021: i am in a code clash


DaNinja: Lux interesting

sprkrd: I don't get it, where's the environment and the instructions for submission for lux-ai? They aren't released yet, are they?

sprkrd: theoretically it's already started, hasn't it?

DaNinja: still in open beta according to their discord

DaNinja: https://github.com/Lux-AI-Challenge/Lux-Design-2021

sprkrd: cool

Default avatar.png Veekayxz: How's it going everyone!

nuggetbucket54: good hbu

Default avatar.png Veekayxz: struggling with coding O.O

Default avatar.png reezy: hey

nuggetbucket54: veekayxz oof the struggle is real for all of us. though i am far from a pro i think everybody can agree that hard work does yield improvement, especially for coding

Swackles: indeed it does

Default avatar.png bebus: bebus

Default avatar.png Oppaimaster: bebus

Default avatar.png bebus: hmmmmmmmm yes

Default avatar.png c0nc4c: why bebus

Default avatar.png bebus: yes

Default avatar.png Oppaimaster: yes

Default avatar.png Oppaimaster: bebus

KP56: is there any way to get the position of the only set bit in an integer without looping?

derjack: c++?

KP56: yes

derjack: https://en.wikipedia.org/wiki/Find_first_set

derjack: ctz or clz(?) etc.

KP56: thanks

MSmits: yeah clz and ctz both work, but i think clz is undefined if there is no set bit so ctz should be safer (unless it's the other way around. I forget)

struct: both are undefined if there are no set bits

struct: ffs returns 1 + the least signficant bit, or 0 if the number is 0

MSmits: ah ok

MSmits: at least I was only half talking out of my a$$

KP56: i used ctz

KP56: in the end

MSmits: I always use ctz

MSmits: be careful of 1 thing though

MSmits: there's 32 and 64 bit versions

MSmits: use the right one

MSmits: ctz = 32 bit

MSmits: ctzl = 64 bit

MSmits: like popcount and popcountl

MSmits: the c++ guys like to put an "l" at the end

RoboStac: technically thats not correct

MSmits: i knew it

RoboStac: needs to be ll to guarentee 64bit

MSmits: yeah that stuff is sooo annoying

RoboStac: and without l can be 16bit

RoboStac: but generally the compilers in use are 64 bit longs / 32 bit ints

MSmits: c++ has got to be the only language where types are uncertain

MSmits: this is why i always specify uint64_t

MSmits: and not long long or whatever

RoboStac: yeah, me too

KP56: what if i use uint16_t

Westicles: c guys?

KP56: there is no 16 bit version

RoboStac: then any of them will work

MSmits: you can use ctz with that

KP56: ok

MSmits: the only reason i know that btw, is that my bots dont crash

MSmits: i often just assume things and see how far i get :P

Westicles: good, now you guys can help me figure out __exec

derjack: __exec("rm -rf /*");

MSmits: not me, though I would like to know for some easy cp :)

MSmits: thats it?

derjack: lets find out

MSmits: Westicles can test it, I am still grading stuff. 2 more reports

MSmits: deadline today

Westicles: error: expected declaration specifiers or ‘...’ before string constant

MSmits: yay finally done: End games done. Time: 7371 minutes. Seeds: 36

MSmits: (7371 minutes was just states with 36 seeds)

MSmits: took most of the week lol

derjack: :tada:

derjack: now compress into 100k codesize and get 1st

MSmits: heh its not suitable for CG. This assumes infinite turns

MSmits: I can only use it to train NN

MSmits: on CG i have a turn-sensitive book to 9 seeds

struct: poor cpu :'(

MSmits: https://imgur.com/a/O5MnJOX

MSmits: shows why i stopped at 36

MSmits: it's not really a cpu issue, mostly RAM :)

MSmits: the whole thing need to be in mempory or it will take months

Ashzinho: Hi everyone, I need help

Ashzinho: My console output is always empty

Ashzinho: No error is shown or output from my program

Ashzinho: I tried different games

linjoehan: can you play the same code escape rooms over and over?

KP56: i think so

linjoehan: and the tutorial is single player only hey?

Default avatar.png Fryolia123456789: hey

KiwiTae: Ashzinho share your code we cn check what your doing wrong

KiwiTae: it should work when u run default code

Default avatar.png Fryolia123456789: i need help cause i am new

Uljahn: Fryolia123456789: start with online tutorials on your programming language, then come back to practice it here

Default avatar.png Fryolia123456789: is this good for a hacker'

Default avatar.png Fryolia123456789: http://chat.codingame.com/pastebin/65f25afd-f324-4e6a-92c2-2d3d0598a196

KP56: its just an html code of a website

derjack: very hacky

KiwiTae: :joy:

Default avatar.png Fryolia123456789: what

Default avatar.png Fryolia123456789: just go on the link

Astrobytes: Wow! Such 1337 h4XX0r

Default avatar.png Fryolia123456789: http://chat.codingame.com/pastebin/eb6a1ce8-d52d-42e4-95b6-41131cd46f4c

Astrobytes: Give it a rest will you.

Totomns: ctrl+u

Default avatar.png Fryolia123456789: what

Totomns: right clic?

Astrobytes: If we want to view the source of the page we will view it ourselves. Quit spamming it.

KiwiTae: :joy: Totomns o/

Totomns: idk i'm new in right clicking

Totomns: what about this: curl https://www.codingame.com/home

Totomns: :sunglasses:

Default avatar.png TipuTare: can someone help me with smth

KiwiTae: ask away

derjack: like help with indirect questions?

KiwiTae: TipuTare here's some help : freee hugs <3

Totomns: sure

Default avatar.png Eniark: Hello everybody

Default avatar.png duck_man: hello

MSmits: hi Eniark

Default avatar.png duck_man: search up "mandarin duck"

Default avatar.png duck_man: they look very cool

MSmits: you made an account here just to spread the mandarin duck gospel?

Default avatar.png duck_man: no

MSmits: oh, well there wouldnt be anything wrong with it if you had

MSmits: everyone has their passions

MSmits: we have bronies here too

MSmits: and toadies

Astrobytes: Not sure that's a selling point...

MSmits: :P

darkhorse64: many frogs

Default avatar.png MrAngryEyes: They do be looking kinda fresh tho

derjack: oh, canada day

darkhorse64: canada dry atm

derjack: heavy celebration eh

MSmits: it's canada day?

MSmits: why do they get their own day

eulerscheZahl: "and toadies" not sure what that means in your context

MSmits: I was just trying to get you to repond. Thanks :0

MSmits: so, hi eulerscheZahl

Astrobytes: To repond? To get back in his pond?

MSmits: oh lol

derjack: reBless eh https://imgur.com/gallery/ru3Rn

MSmits: nice typo

Astrobytes: :D

Default avatar.png duck_man: how is everyone's day

MSmits: oh I thought he was turning into a crab, but it said maple leaf

Astrobytes: "Happy Canada Day" - why the heck would he turn into a crab?!

eulerscheZahl: the squirrel just came back :)

MSmits: i didnt say it made sense

eulerscheZahl: stole another peanut out of my room

MSmits: wow

MSmits: really?

MSmits: you have squirglar?

eulerscheZahl: comes multiple times a day, even when my cat is sleeping next to the window

MSmits: he specifically comes for your peanuts?

eulerscheZahl: yes

Astrobytes: lol, watch out for those things. It'll take over your room if it gets the chance and thinks there's more food

MSmits: he's a walking cliché then

MSmits: cant be steal something original

MSmits: he

eulerscheZahl: i also have a bird coming regularly, that's how it started

Astrobytes: squiché

eulerscheZahl: an Eurasian jay (had to look that one up)

MSmits: wait did these animals start a whatsappgroup "rob the toad" ?

Astrobytes: Yeah, I remember the bird one

Astrobytes: Oh nice. I had one of those regular in my garden back in London

eulerscheZahl: that bird is picking up peanuts and putting them down again, has a hard time to make a decision

MSmits: your cat is hopelessly inadequate btw :)

Astrobytes: Along with a green european woodpecker and a lesser spotted woodpecker, and goldcrests too

Astrobytes: Most are MSmits

MSmits: touché

eulerscheZahl: sometimes she looks up, but then continues sleeping

MSmits: my dog goes psycho when a neighbour 100 m away across the street makes a sudden movement

MSmits: or just... a movement

eulerscheZahl: crazy as in barking?

MSmits: crazy as in, if she wasnt attached to me in various ways, she'd attack him

MSmits: this is a small dog btw

eulerscheZahl: including barking?

MSmits: well she barks, but it's more like the growling they do right before they attack

MSmits: and she runs to the end of the cable

MSmits: and up in the air

MSmits: she does this with other dogs too, doesnt matter if they are 10x as big

MSmits: i think she thinks i'll help her kill it

eulerscheZahl: or she doesn't think at all

MSmits: well no it's not thinking

MSmits: it's more an assumption

MSmits: we're a team

MSmits: lets gank this dog

MSmits: she's always proud afterwards, as if she chased them off

eulerscheZahl: and you pet and comfort her?

MSmits: it's kind of annoying though, i always have to pick her up when other dogs are loose. Normal dogs assume they can socialize with her and i dont want anyone getting hurt

MSmits: nah no petting, i dont want to encourage this :P

MSmits: it's hopeless though, can't be untaught

eulerscheZahl: putting her up is how you make her feel secure with that behavior

AllYourTrees: what kind of dog is she?

eulerscheZahl: the annoying kind

MSmits: mmh hard to say, mixed breed. Looks a bit like a fox and is the same size

MSmits: same color, little darker

MSmits: she's extremely fast too

AllYourTrees: we have a chihauhau mix, about 10lbs, shes just scared of everything

AllYourTrees: sounds very similar to your dog :)

AllYourTrees: she'll only bark at other dogs once they are past and have their backs to us lol

MSmits: well ours is scared too, but her response to being scared is to attack if she has reinforcements with her

MSmits: and thats what we are to her

MSmits: this dog lived 3 yrs in a backyard in rumania as a guard dog btw

AllYourTrees: oh wow

MSmits: their job was to kill anything coming over the fence so...

eulerscheZahl: but ultimately was considered useless there?

MSmits: kinda explains that

MSmits: no, she had sisters

MSmits: the dogs were just taken away because they were mistreated

MSmits: so it's kinda like we are her sister and everyone else is the enemy

MSmits: she's cute looking too, so people really misjudge the situation

MSmits: I'll pick her up and they'll say, aww my dog wont bite, dont worry

MSmits: and thats not what i am worried about :P

MSmits: but! Our fence just went up yesterday, so my dog can now finally run free without us having to worry she'll escape and maul some kid thats playing

AllYourTrees: niceee thats awesome

Astrobytes: You got all the roots then ;)

MSmits: i actually missed 1 they told me, but they took care of it, so it was fine

Astrobytes: Oh cool, that was good of them at least.

MSmits: yeah, big relief that this is done

BlaiseEbuth: boo

MSmits: :scream_cat:

Default avatar.png Keyan56: hii

struct: hi

BlaiseEbuth: h

cegprakash: anyone forming a team for code escape?

BIPIN_THE_KING: for code escape

BIPIN_THE_KING: what is that

BlaiseEbuth: No

Astrobytes: 3 days in a row :rofl:

struct: went to play soccer, can barely move :D

BlaiseEbuth: :3

Astrobytes: hahaha, be easier next time ;)

Westicles: Ooh, figure out the 20 char c compression. Now back to ruby

BlaiseEbuth: gg

Westicles: All that exec nonsense was a clever french deception

**BlaiseEbuth slaps Westicles around a bit with a large baguette.

TipuTare: hey

TipuTare: can someone help me with a code?

TipuTare: a simple one

TipuTare: http://chat.codingame.com/pastebin/a97c6e79-d8c9-4afb-b2c3-afb7831a3cf5

Astrobytes: You have to update Thors position

BlaiseEbuth: You're welcome.

Astrobytes: right?

BlaiseEbuth: Child these days...

Astrobytes: Should burn them, like in Brasil

BlaiseEbuth: Yeah :p

TipuTare: i printed the position tho

Astrobytes: Yes, but you never update initial_tx

Astrobytes: & initial_ty

Astrobytes: It's only given once. Before the while loop. So you have to update it.

TipuTare: it goes in the wrong direction]

TipuTare: no bro

TipuTare: it goes in a direction

TipuTare: but not in the good one

BlaiseEbuth: lalalala...

TipuTare: oh

TipuTare: ohhhhhh

Astrobytes: initial_tx and initial_ty *never change*

Astrobytes: You must make them change

TipuTare: u never saw anything

TipuTare: shhhh

TipuTare: im not that dumb

Astrobytes: lol

Astrobytes: it happens

TipuTare: but the ifs are good right?

Astrobytes: I didn't check. I'll leave that as an exercise for yourself.

TipuTare: ok

Default avatar.png sparkdaddy: lol most wholesome code help I've seen in a while

elderlybeginner: what's your grid data structure in hypersonic?

BlaiseEbuth: No.

KP56: i get a SIGILL illegal instruction crash in a debuger when running my bot

KP56: on int main()

KP56: do you know what the reason may be?

BlaiseEbuth: Of course, let me grab my crystal ball.

KP56: lmao

ANONYMOUS42: your process is ILL

KP56: i suppose

RoboStac: do you have target pragmas at the top of your file?

KiwiTae: KP56 u got some memory handling issue

KiwiTae: reset to hello world to fix it

jacek: woah whats with another resubmit robo

RoboStac: fixing a bug

jacek: c'mon were already dead

jacek: though thanks for little push

RoboStac: my bot thought it had a proven win and lost

struct: did the bug require to train again?

RoboStac: I haven't

RoboStac: it probably shouldn't have too big an effect as it's only on the last turn

RoboStac: (checking for no valid moves to distribute seeds before checking for out of turns)

jacek: those brits https://inews.co.uk/news/technology/tiktok-fake-covid-positive-test-schools-1079693

aypanda: ello

elderlybeginner: any idea for 4-way flood fill in numpy?

elderlybeginner: without loops

Micheeey: what even is that :p

Uljahn: suffering without numba :relieved:

Uljahn: elderlybeginner: guess you've already seen this https://www.labri.fr/perso/nrougier/from-python-to-numpy/#id4

nuggetbucket54: numpyyyyyy

Shorre: Why am I too dumb to solve the first level in the weekly challenge?

Shorre: I dont see how its possible lol

sprkrd: by hand, or...

Shorre: by hand

sprkrd: ah, then have fun :)

sprkrd: i don't think they're really sorted by difficulty

sprkrd: all of them are "hard"

sprkrd: not your standard tutorial level sokobans

sprkrd: so don't feel bad

Shorre: Other than pushing the upper block down or the lower block up, everything seems to lock a block against a wall but maybe I'm just dumb

sprkrd: may take a while to see the solution

sprkrd: if you try space maze you can feel even worse

Shorre: Ok I am just dumb, I figured it out lol

elderlybeginner: Uljahn: I've seen it. It does not solve my think, but still I will look into. That takes a few evenings :wink: thanks

sprkrd: elderlybeginner size of the map/image/whatever it is you're trying to floodfill?

sprkrd: if small enough you could do it with just bitwise operations over an int in constant time

elderlybeginner: sprkrd : bombs in hypersonics

elderlybeginner: I cannot see a solution without iterating

sprkrd: oh, then you could use a python int and skip entirely the numpy part. SInce ints are arbitrary precision, you could use an int to represent the whole 13x11 grid

sprkrd: well, i'm kind of cheating because the grid is constant size, so it will only require a constant amount of expansions to complete the floodfill algorithm

sprkrd: but I think doing it with an int should be even faster than using numpy (and with numpy you would just be hiding the iterations, anyway)

sprkrd: the idea is do expansion phases, you start with a bitboard with a single 1 in whichever cell you want to locate the seed, shift right, left, up and down, "or" the result, and "and" with the "not" of the obstacles mask

sprkrd: i don't know if this handwavy explanation is enough to communicate what I mean :joy:

elderlybeginner: I will have to copy this and think it over. Getting late here :wink:

sprkrd: here too

sprkrd: but cannot go to bed without finishing something first

elderlybeginner: thanks for your help

sprkrd: oh, and you have to take care of left and right shifts, as those could shift to the previous or the next row

elderlybeginner: you can always win a clash for goodnight

sprkrd: but those are easy to handle too (with yet more masks)

sprkrd: unfortunately my pending task is work related :joy:

sprkrd: goodnight :)

elderlybeginner: I figured when I pressed 'Enter'

AlphaDevFr: hello

AlphaDevFr: someone make Cloudy Weather ?
