KayKay1202: How many ppl are here
ipsissimus: 4 people
ipsissimus: 1 sage
Wontonimo: 1 tomato
ipsissimus: i had a job interview today
ipsissimus: hopefully i did good
ipsissimus: really need that income
Wontonimo: yeah !
Wontonimo: i hope so too
Thorcode: Good luck ipsissimus
ipsissimus: was for a company that wants to do facial recognition as 2FA
Broso56: hopefully it goes well!
Thorcode: ipsissimus try your best
ipsissimus: im not raising my hopes
ipsissimus: that way i cant get rekt
**Thorcode hope ipsissimus pass
ipsissimus: wasnt a coding interview. i just talked alot about project management
ipsissimus: threw alot of mythical man month jargon out there
ipsissimus: :O
Thorcode: idk but I still wish you pas
Wontonimo: hey ipsissimus, I hope *random platitude* for for you. And don't forget *irrelevant tangent idea* always helps
ipsissimus: indeed
Wontonimo: did you joke with the interviewer and actually make them smile?
Wontonimo: i don't mean knock-knock jokes
ipsissimus: i tried. im pretty charismatic under pressure
ipsissimus: but who knows what theyre thinking
Wontonimo: awesome
ipsissimus: i really want it, i have a meeting with a FB recruiter and a Florida Power & light manager on monday
ipsissimus: and im dreading those
Wontonimo: well, i'm tired
Wontonimo: I'm gonna go do that think where you lie prone and lose consciousness
Wontonimo: later :wave:
ipsissimus: die?
ipsissimus: dont do it
KayKay1202: Do we wanna join a Google meet everyone
ipsissimus: theres so much code to write
KayKay1202: ? Or nah
ipsissimus: nah
KayKay1202: Fair enough hah
ipsissimus: I shleep
ipsissimus: :v:
KayKay1202: Hey
KayKay1202: Anybody here
KayKay1202: :sob:
Broso56: https://www.codingame.com/replay/587329280 theres no way this just happened 😂😂
KayKay1202: HELLO?
KayKay1202: ANYONE??????
jacek: happy Caturday
KayKay1202: you too.
KayKay1202: hey guys
ziggityzaggity: yo
Broso56: hey
KayKay1202: hello
ProCoder03: hello
JHBonarius: Wait, why is "Coders strike back" now called "mad code racing"?
JHBonarius: sorry "mad pod racing"
TheBlueBias: Copyright issues fear...
JHBonarius: the joke used to be that all competitions had something like "code" in it
eulerscheZahl: and a reference to a movie
JHBonarius: The link is still /ide/puzzle/coders-strike-back and it states the title in the opening screen
TheBlueBias: Enough fear to do something, ,oy enough to do it correctly.
TheBlueBias: *not
JHBonarius: Tron has also been renamed...
JHBonarius: Disney :rage:
TheBlueBias: And others...
TheBlueBias: Well, Disney said nothing, CG done it by anticipation
JHBonarius: hmm, indeed pirates of the Caribbean is also Disney, but that hasn't been renamed
jacek: lets call them :imp:
JHBonarius: Seems they only use email
JHBonarius: hmm, vs code is weird
JHBonarius: I open a folder. Add a subdirectory. Want to add a second subdirectory, but it adds it below the existion subdirectory, instead on in the top directory
TheBlueBias: Yeah. You have to click the parent directory first.
JHBonarius: I did
TheBlueBias: Hm... I generally use a right click on the directory instead of the generic button.
JHBonarius: If I click it, it collapses the whole directory tree and the "add directory" icons dissapear
JHBonarius: Yeah, so that doesn't work for the top level directory/root
eulerscheZahl: JHBonarius i can assure you the list of games that need renaming or other changes is longer. it's just the first few that have been renamed already
JHBonarius: Ah, found it. You have to right click somehwere in the tree pane, not on some existing directory or file
JHBonarius: very intuitive... not
JHBonarius: eulerscheZahl sad times
eulerscheZahl: yes :(
eulerscheZahl: that and the missing contest
eulerscheZahl: no community contest either. I even gave them a finished game and they refused
https://www.codingame.com/multiplayer/bot-programming/tryangle-catch
TheBlueBias: Ah, for the top directory, yes... Need time to integrate this behaviour...
JHBonarius: i think it's because they are jealous of your skills
eulerscheZahl: they figured out that only 1.64% of their users come to compete in a completely transparent poll
JHBonarius: I'm using VS 40+h a week, which is weirdly different
eulerscheZahl: what is that add directly that you are talking about now?
JHBonarius: vscode intuitive interface
eulerscheZahl: ah. i use VS Code at home
eulerscheZahl: VS at work
eulerscheZahl: no VS for linux
JHBonarius: it worked. I'm backing up all of my bots now. I had some files on my drive but found the online bots differ. Don't know what happened there
JHBonarius: how are you doing by the way
eulerscheZahl: i'm fine. just trying a few other contests outside of CG
eulerscheZahl: and remote working for a long time, only 4 days in office in 2021 so far
TheBlueBias: linux -> virtualbox -> windows vm -> vs. EZPZ
JHBonarius: oh wow. I that typical for where you live?
eulerscheZahl: lots of colleagues go to the office. but i'm pretty much the only programmer in a team of CAD designers
eulerscheZahl: so my presence isn't really needed. and still not too many people wanted inside the office
JHBonarius: YEah, if it works out it's good.
I work better at my office. less distractions.
In NL people are talking about the "new normal" where there's a lot of working from home
eulerscheZahl: similar here. my company only demands 45% of your days spent in office (business trips count as office)
eulerscheZahl: they even offered 100% i've been told, but employee representatives didn't agree on this one (fairness to others who can't work remotely)
JHBonarius: 100% what? in office or from home?
eulerscheZahl: 100% remote
eulerscheZahl: optional, employees can still go to the office
eulerscheZahl: just as an offer
JHBonarius: ah. yeah. I think that's seriously considered now. Altough I don't like that some companies are reducing pay for people that work from home
eulerscheZahl: they do?
JHBonarius: yeah google did that
JHBonarius: LOL!!! My legends of code and magic bot doesn't compile anymore!
JHBonarius: std::random_shuffle has been removed in C++17
eulerscheZahl: RIP
JHBonarius: tha's funny. code rot
eulerscheZahl: C# is less prone to this kind of breaking change
jacek: can there be nonrandom shuffle?
JHBonarius: 2 years :skull:
JHBonarius: Yeah: the dance
jacek: quick sort dance?
JHBonarius: Yeah, I know that one
JHBonarius: it's std::shuffle now
JHBonarius: but all stl stuff... non-optimized...
I can't remember... was algo speed important for LoCM?
eulerscheZahl: let me know if your new submit reaches top100, then I'll index you
eulerscheZahl: not that important
eulerscheZahl: interesting: you say your bot doesn't compile anymore. but your arena version is still working
JHBonarius: hmm, seems to work fine in IDE. My local build just fails....
I remember us all copying the card "values" from this guy who won (?)... He used ML to get those. long long ago
eulerscheZahl: ClosetAI
eulerscheZahl: but no ML involved
JHBonarius: No? I thought he was doing value training on simulated battles on a server?
eulerscheZahl: he just ran millions of games where he played one card vs another while giving the same set of other cards to both bots
eulerscheZahl: that's not machine learning
JHBonarius: are we going to have that discussion? :rolling_eyes:
eulerscheZahl: or at least not my understanding of that term
JHBonarius: I think it's ML, it's not a NN
TheBlueBias: :popcorn:
eulerscheZahl: want a different discussion?
JHBonarius: training regression models is also a form of ML
JHBonarius: git fun
JHBonarius: new repo. trying to add files...
JHBonarius: "unable to merge unrelated histories"
JHBonarius: what? it's a new repo
JHBonarius: trying to remove the .git directory
JHBonarius: "you need administrator privileges to remove this" -> ok elevate
"denied.. you need permission from [local user] to remove this"
wait what?:tired_face:
JHBonarius: wsl2 rm -rf .git works fine...
JHBonarius: you need to use wsl to do simple windows filesystem operations...
JHBonarius: again "fatal: refusing to merge unrelated histories" vs code github integration sucks
eulerscheZahl: why don't you just use the command line?
JHBonarius: I should. I hoped VS cdoe would make life easier
smallPPperson: #clash
jacek: ML talking?
jacek: why it keeps turning :( https://streamable.com/om3wud
DomiKo: Tokyo drift all the time
MSmits: my 7x7 c4 solver still going. I think it will be a full day
MSmits: biggest solved by John was 8x8. That will indeed take a long time
MSmits: nice drifting btw
jacek: you dared to click my link
MSmits: I trust you
MSmits: I am naive like that
TimothyAlexisVass: :peach:
flame568: ok
Ellain: sup guys, is it worth to learn concurrency? does anyone use threads here?
Ellain: std::thread::hardware_concurrency() returns 8
flame568: i am new
JFB: jacek - are you schure that your bot can turn right?
jacek: right is for the noobs
MSmits: yeah, if you make it work for left first, you can just add a minus sign to your program and it works for right turns too
darkhorse64: MSmits: what if you made your TT size as a power of 2 ? You could get rid of the % and save precious ms
MSmits: ah yeah that's true
MSmits: thanks
MSmits: where did that come from suddenly lol
MSmits: random optimization advice
MSmits: how would you do it with a power of 2 by the way? Just mask the higher bits?
darkhorse64: I saw your TT implementation very late (completely out of sync with the chat) quite some time ago and forgot to tell you
MSmits: ah ok
darkhorse64: if SIZE is a power of 2, just and with SIZE -1
aangairbender: what is TT by the way?
aangairbender: transposisiotn table?
darkhorse64: yes
MSmits: ok, will do that
MSmits: probably will be negligible, but it's good to be thorough
darkhorse64: A scarce ressource has a high value, ms are CG gold
darkhorse64: :slight_smile:
darkhorse64: file size too
MSmits: int key = HashKey(boards[0], boards[1]) & (HASH_CAPACITY - 1);
MSmits: HASH_CAPACITY = 524288;
darkhorse64: Correct
MSmits: great
JFB: Do you remember2^n up to n > 19?
UntitledEpicness: Yo
darkhorse64: Was your previous 400K based on tests ? Up to 2^31
darkhorse64: Kidding
MSmits: 400k was sort of based on test. I did not see much difference between 200 and 600k
MSmits: plateau
darkhorse64: Just in case 256k is enough
jacek: 640kb is enough
MSmits: i guess i'll test it when i feel like testing
MSmits: how do you know jacek?
darkhorse64: jacek: I really hope you would say it
aangairbender: guys you know how to use simd with rust on codingame?
MSmits: it kind of depends on the game. C4 has a lot more expansions than yavalath, so more use of the table
jacek: rust? D:
darkhorse64: Sorry, aangairbender, I am C++ only with all due respect to Rust
aangairbender: my rust code worked after first submit, my identical cpp code didnt work after hour of debugging
TheBlueBias: I like rusty spoons. :salad:
Sebastogne: i like you
MSmits: i like me too
JFB: MSmits: about 650 k said Bill Gates
JFB: *640
aangairbender: :joy:
Asuki: ```go
Hello
```
Sebastogne: x^2+1=0
witer33: oke
darkhorse64: aangairbender: Once you convince the compiler your Rust code is compliant, I feel your chances for something correct are greater
aangairbender: darkhorse64 that's true:sweat_smile:
MSmits: don't understand the bill gates reference
aangairbender: seems like only sse and sse2 are supported (not avx, avx2, sse4.1)
darkhorse64: MS-DOS time when you could not access more than 640K, Bill Gates said 640K would fulfill all your needs
MSmits: ohh ok
darkhorse64: We have all forgotten but programming on PC/MSDOS was nightmarish
MSmits: ah i could not code back then
JFB: we had lower expectations then darkhorse64
MSmits: but just using a PC was nightmarish, so i can imagine
JFB: first turbo pascal looks as some kind of magic - it was soooo fast - you write code, press one button and have running program.
MSmits: some PC's had a turbo button :P
JFB: of course in 1980s
MSmits: I was always wondering why they had that. I mean why would you ever want it to be slow
JFB: Yes - and you sometimes do not use it becouse same games run too fast with this button :-)
dreadylein: legacy reasonses
MSmits: ohh ok
dreadylein: most software just run as fast as the cpu could execute it
MSmits: so this was before they figured out how to not make game speed dependent on cpu speed
dreadylein: not only games but yeah hehe
MSmits: this is a funny game: https://www.codingame.com/replay/587388854 Two bots same code. Red solves as loss, then blue makes a mistake and it becomes a draw. That's mcts randomness for you
JFB: playing digger (pac-man clone) on 386 was a purely random game (for speed reasons)
MSmits: it should have been possible to introduce time.sleep(x) lines into the code to slow it down to match your cpu
MSmits: they could even have made a game menu setting where you could manage the speed like this
JFB: of course - but I have has only *.com (or *.exe - I do not remember) so you have had to disssemble to add sleep
MSmits: ahh
JFB: it was pirates copy of course
MSmits: naturally
struct: hi
aangairbender: hi struct
Kepe55: Any good online whiteboard you guys recommend?
DomiKo: https://miro.com/signup/
Kepe55: thanks, do you use that?
DomiKo: yes
DomiKo: miro give you 3 infinite boards for free
DomiKo: you can share them to your friends
DomiKo: and they work in real time!
Kepe55: alr thx
69razer69: noice
TimothyAlexisVass: http://chat.codingame.com/pastebin/8f4f7cf4-5c5e-4772-bc8f-77a5b12028d1
eulerscheZahl: 3 infinite boards you say :thinking:
eulerscheZahl: infinite is pretty big, i'm tempted to test that now
DomiKo: I have one board for every CG game
eulerscheZahl: *for those you played
eulerscheZahl: btw your MPR bot is interesting. completely deterministic
DomiKo: yeah it should be
DomiKo: I'm doing depth 1 search + NN
DomiKo: no random indeed
eulerscheZahl: i assumed a neural network
eulerscheZahl: my bot comparison spotted the deterministic behaviour
DomiKo: :scream:
DomiKo: that bot isn't great, but it require a lot of time to improve :(
eulerscheZahl: it's top40 at least
DomiKo: without depth 1 It was like top120
eulerscheZahl: that is depth0?
DomiKo: yeah
DomiKo: I believe I could code in C++ and results would be much better
struct: wait this is true py3?
DomiKo: yes
struct: o.o
struct: step 1 c++, step 2 avx, step 3 NN
DomiKo: if I would do this for CG, then yes. But that was a project for uni
DomiKo: that's why euler thought that magma is my second account, because its same code, but different NN
struct: oh I saw that account somewhere
struct: maybe on uttt or something
DomiKo: yeah
DomiKo: UTTT is a first task at acat lecture
eulerscheZahl: yeah, it popped up here and I was confused as I didn't expect to find anything in a physics game: https://eulerschezahl.herokuapp.com/codingame/leaderboards/?game=coders-strike-back
TheBlueBias: Oya here
eulerscheZahl: while others such as codebusters light up like a christmas tree
TheBlueBias: What's your next planned contests eulerscheZahl?
TheBlueBias: *are
eulerscheZahl: maybe Coder One, not sure yet
DomiKo: I love this one:
DomiKo: https://eulerschezahl.herokuapp.com/codingame/leaderboards/?game=hypersonic
TheBlueBias: erf
eulerscheZahl: i think it's just 1 bot. but random so it looks like it's a few different ones
eulerscheZahl: i could keep regenerating games until it's all the same
eulerscheZahl: it also has user profiles, if you click a nickname
DomiKo: how you check this?
eulerscheZahl: play bot vs itself. compare the gameplay (that is actual action, not output including message)
eulerscheZahl: and of course i didn't play all these games by hand
DomiKo: nice idea
TheBlueBias: Hmm... And what are the RAIC date?
eulerscheZahl: february
TheBlueBias: Bwarf...
eulerscheZahl: no more details known to me
TheBlueBias: Don't even see that on the website...
eulerscheZahl: yare probably around a similar date
eulerscheZahl: they sent an email explaining that it's postponed until 2022
eulerscheZahl: in Russian
eulerscheZahl: i translate all those mails to make sure that I don't forget to claim my tshirt/hoodie
TheBlueBias: ^^
eulerscheZahl: they tend to ask you to enter your shipping address until date X
eulerscheZahl: then at X+something they ask you again as there was a huge delay
TheBlueBias: Icy
eulerscheZahl: they save your inputs. but you still have to confirm them
TheBlueBias: Oh? Bomberman is by team?
TheBlueBias: Or it's because you control multiple characters?
eulerscheZahl: i think it's still 1 vs 1 in terms of AIs
eulerscheZahl: didn't read the rules
eulerscheZahl: still in open beta. contest is planned to start on december 3rd
TheBlueBias: Me neither. It's because of "Top 8 teams battle it out live on Twitch!"
eulerscheZahl: with some prizes each month and a big finale later
eulerscheZahl: oh, that's the downside: they don't play tons of games for each bot
TheBlueBias: I'll perhaps take a look so...
eulerscheZahl: they launch the games manually. just a few of them
eulerscheZahl: => more randomness
eulerscheZahl: also knockout at the end
eulerscheZahl: each vs each to determine finalists
eulerscheZahl: (at least that's how it was last time)
eulerscheZahl: i decided not to play. ValGrowth won. dapo 3rd
TheBlueBias: I'll see. December is in a looooong time.
eulerscheZahl: i know. i have no contest plans until then :(
eulerscheZahl: topcoder marathon was too close to huawei
TheBlueBias: The snake thing?
adamgosnell: Hey everyone! I'm working on Horse-racing Duals, and I'm failing on test case #3 (Many horses). It looks like my code works, but the test is failing?
adamgosnell: Can you explain what's happening?
adamgosnell: Here's the error:
Failure
Process has timed out. This may mean that your solution is not optimized enough to handle some cases.
adamgosnell: Does that mean it takes too long?
TheBlueBias: Yes
Marcorvar: You may have too many for loops in place :)
Press_F_to-Cesar: jojo
adamgosnell: Thanks, bearnilu! I was sorting in a for-loop, was taking to much time.
Astrobytes: Press_F_to-Cesar: Do you honestly have nothing better to do than come here every day and talk about 'jojo' randomly without ever doing anything else?
What is your major malfunction?!
bearnilu: :) you are welcom
eulerscheZahl: have you heard the story about the ship that had jojos loaded? it sank 207 times
SunnyGiant_e433: Hi I am working on "There is no Spoon - Episode 1" and I get the following Warning: your code did not read all available input before printing an instruction, your outputs will not be synchronized with the game's turns and unexpected behaviour may occur.
The test case is failing...in my local IDE, the output stream is different...Any ideas?
SunnyGiant_e433: I read all input before any cout statement
Astrobytes: eulerscheZahl: Oh I get it now, "yoyos"
eulerscheZahl: i ruined the joke then :(
Astrobytes: nah, I still groaned :D
eulerscheZahl: that's the best reaction to a lame joke :D
Astrobytes: exactly!
jacek: oO
jacek: is this jojo reference
JFB: eulerscheZahl - what "open beta" contest have you talked about? By the way - congratulations on 2nd place in yare.io
eulerscheZahl: thanks :)
eulerscheZahl: gocoder.one
eulerscheZahl: the Bomberland game
JFB: OK.
JFB: Have you win etherum?
eulerscheZahl: i got 0.3ETH as announced. already received it the day the contest ended
jacek: only cg coins
jacek: did you sell them
eulerscheZahl: the main slowdown was that I had to figure out how to create a wallet. so huge shoutout to yare organizers
eulerscheZahl: i kept it. and ETH is going up
JFB: eulerscheZahl - delete this post (tax police is looking )
jacek: < Caturday> 1 BTC - 61137 USD, 52505 EUR, 44437 GBP
eulerscheZahl: i don't even know how taxes apply in such cases
JFB: ETH noit BTC
jacek: its kind of correlated isnt it
eulerscheZahl: it is
eulerscheZahl: but I don't have 52505€ * 0.3
JFB: 1 ETH = 0.06584403 BTC (actually)
struct: not sure if tax is applicable but might be different in germany
eulerscheZahl: also no idea about the huawei smartwatch. does that require taxes?
eulerscheZahl: illedan had to pay when he received his 3rd price for Sogeti (the fantastic bits variation)
eulerscheZahl: but that's Norway
jacek: nandway
eulerscheZahl: i know that you don't have to pay taxes in Germany if you win the lottery
jacek: can i be your citizen plx?
TheBlueBias: Viking gonna plunder...
eulerscheZahl: just looked it up: when it's mostly luck-based you don't have to pay taxes (lottery, sports bets, ...)
when it's more about skills, it seems that you have to pay
struct: just say it was luck
eulerscheZahl: https://taxfix.de/steuertipps/gewinne-bei-lotto-und-quizshows-versteuern/
not sure how reliable that source is
JFB: In poland I think is around 20% tax from the lotery (it depend on the kind of the lottery)
jacek: yare was rng?
eulerscheZahl: there was a bit of RNG
JFB: mam ból głowy z nagrodą z topcoder'a - na szczęście dopiero w kwietniu 2022 - ale się tego boję bo mogą mi zakwestionować jak to zaklasyfikowałem. Zobaczymy. Prawdopodobnie jak bym dostał cryptowalutę to bym tego nie zgłaszaał
JFB: Sorry
eulerscheZahl: uhm, yes
eulerscheZahl: kick next time ;)
jacek: oO
JFB: I have a headache with a topcoder award - luckily not until April 2022 - but I'm afraid of it because they might question me how I classified it. We'll see. Probably, if I got a cryptocurrency, I would not report it
eulerscheZahl: not telling anyone about it makes life easier
JFB: ye
JFB: best way not telingg - is telling in CG chat ;-)
eulerscheZahl: good thing that I never leaked my real name :see_no_evil:
JFB: :-D
JFB: and address :-)
struct: just tell dbd r to delete the logs
JFB: or all internet (delete) ;-)
eulerscheZahl: i'll do where facebook failed
JFB: it looks that fb have new fail everyday
jacek: fantastic bits is alright
JFB: :-D
eulerscheZahl: as long as it's still "fantastic bits" :imp:
jacek: any copyright there?
jacek: because its abbrevation is fb?
bearnilu: lol
eulerscheZahl: JFB might not get that joke. CG is renaming some games. like CSB => mad pod racing
JFB: :-)
TheBlueBias: Frodo Baggins
eulerscheZahl: Fantastic Beasts
TheBlueBias: For Beer!
JFB: So was my surprise today - I saw post about mad pod racing - and replay from CSB
eulerscheZahl: Tron => Line Racing
eulerscheZahl: Skynet => Death First Search
JFB: Really?
jacek: onitama => ban?
eulerscheZahl: and 1 more puzzle was renamed, what was it again?
jacek: batman?
eulerscheZahl: they won't handle community contributions for now
TheBlueBias: Tron => Blaise's Line Crossing
JFB: Maybe some copyrigt problem?
eulerscheZahl: Thor artwork
jacek: didney
eulerscheZahl: it's all about copyright, yes. getting into the US market with that acquisition
JFB: Nobody wants to go to court with Disney for CSB
eulerscheZahl: last crusade => the fall
JFB: copyrgth law === the big evil
eulerscheZahl: https://www.youtube.com/watch?v=m2VxpTMAbas
JFB: :-)
JFB: But with fantastic bits it looks that facebook plan to change its name. I thought that change is due to "image problems" but maybe it is due "fantastic bits" ;-)
AllYourTrees: no ifs ands or bits about it
struct: what was csb copying?
eulerscheZahl: empire strikes back
struct: lol
eulerscheZahl: read mods channel, contains valuable hints for people like us who aren't that firm in cinematic questions
AllYourTrees: okay color me confused... i added selecting a random child 75% of the time in MCTS in C4 and its beating smits :thinking: with no random moves it loses...
struct: retrain your NN
struct: They will need to change the links too right?
jacek: mods channel?
struct: yes #mods
eulerscheZahl: the one you decided not to join
JFB: AllYourTrees - maybe random moves confuse smits' bot - its think so long that it is timeout ;-)
AllYourTrees: lol
eulerscheZahl: or you found a way around his opening book
jacek: for uct i have random [0.9,1.1] * eval + C * sqrt(...)
AllYourTrees: oh ya the opening book, good point
AllYourTrees: oh thats cool jace ty for sharing
struct: almost perfect triangle
struct: https://www.codingame.com/replay/587426586
eulerscheZahl: to get the perfect triangle, one has to play tryangle catch
jacek: its nothing vs connect7
struct: only your bot can achieve that
struct: https://www.codingame.com/replay/586948031
struct: replay from a few days ago :/
jacek: how did you lose against that noob
jacek: i need to be more patients. 100th vs 1000th generations. https://streamable.com/p3jd28
jacek: at first i put more emphasize to just finish the games, then when most games are finished, the fitness for duration kicks in
jacek: maybe thats why it keeps steering into one direction
struct: i added your rng thing and finally I can win some games vs NNs
jacek: huh
struct: i made my selection a bit random sometimes
jacek: but pure mcts is inherently random, no need for that?
struct: maybe its just rng from submit
jacek: maybe you need more exploration
JFB: jacek - this racing bot is NN or what?
jacek: my trials at NN
Chelbeb_Mohamed: que pasa hejo de espagna ?
jacek: oO
ja_fica: I have one question, is PUCT superior to UCT?
jacek: PUCT requires policy probabilities no?
jacek: its like comparing oranges to apples :?
69razer69: i tried running the game template on eclipse and i got error caused by : java.lang.reflect.InaccessibleObjectException
eulerscheZahl: interesting, i can't remember getting that error
eulerscheZahl: which java version?
69razer69: java.runtime.name=OpenJDK Runtime Environment
java.runtime.version=16.0.2+7-67
eulerscheZahl: that's a really new one. i use Java11 when I do anything SDK related
struct: I use 8
struct: also I dont use openjdk when I do sdk stuff
69razer69: so its just a matter of dozngrading
69razer69: *downgrading
**eulerscheZahl uses OpenJDK

KelvinAndHubbles: Like when you run a test case and it times out.
KelvinAndHubbles: How long does it run for before it throws timeout error
struct: I think it depends on the puzzle and language
KelvinAndHubbles: KK, fair enouigh
TheBlueBias: But that's more about ms than seconds
eulerscheZahl: for a classic text-based puzzle it's 1s I think
eulerscheZahl: but different languages even have different timeouts i've been told
jacek: handicap for python eh
eulerscheZahl: you can bruteforce rollercoaster in JS but not in C++
eulerscheZahl: take that!
eulerscheZahl: struct can confirm
struct: yeah
struct: the js code can run up to 6 sec on that puzzle I think
struct: while c++ has like 1 sec
VizGhar: yeah but it looks more like a mistake from CG?
TheBlueBias: CG makes no mistakes.
eulerscheZahl: the different time limits are a feature
VizGhar: o.O :D explain following contest then :D
eulerscheZahl: research told them it's a good idea
eulerscheZahl: only 1.64% are here for contests anyways
TheBlueBias: Ultra accurate surveys
cruelnerd: 31
eulerscheZahl: 42
TheBlueBias: 666
SmokingJoe: does anyone here maybe has a c++ merger to upload a project as single file ?
TheBlueBias: I have
TheBlueBias: https://github.com/BlaiseEbuth/CGppMerger
cruelnerd: guys im noob at devolopping. im stuck with doing these things. ı feel like dumb, i cant even solve basic problems.
SmokingJoe: ohh thx a lot
eulerscheZahl: a c++ merger written in c++
my C# merger is in python
TheBlueBias: I'm a purist.
aangairbender: SmokingJoe there is codingame-merge npm package
TheBlueBias: npm :scream:
eulerscheZahl: npm package for C++ bots?
aangairbender: at least its easy to use
aangairbender: my c# merger is in c#
eulerscheZahl: mine is just a few lines that I run on compilation
aangairbender: I analyze namespaces and usings as well
eulerscheZahl: i do the same for usings, making them unique and putting them at the top
eulerscheZahl: i code without namespaces to solve that problem
aangairbender: yeah same for uniqueness of usings
TheBlueBias: I use it with CGLocal. So I can just click "build" in VSCode then click run on CG.
eulerscheZahl: also constructs like
using(IDisposable someObject)
would get mistaken for a library import
aangairbender: visual studio creates namespaces by default, so they are supported
eulerscheZahl: i just delete them when I create a new file
eulerscheZahl: my script might work with namespaces but i don't see a need to have them
eulerscheZahl: only adds an extra level of indent, overkill for small projects like CG bots
aangairbender: I guess if using namespaces, there is extra indentation before using(disposable)
aangairbender: so following line.StartsWith("using") wont detect it
eulerscheZahl: same. but if i would try to trigger it with bad formatting, my merger could break
MSmits: I write 3k line bots in 1 file :grin:
MSmits: like a boss!
TheBlueBias: And you pay for papers. What an example for children...
MSmits: there was *1* paper :rage:
TheBlueBias: :smirk:
MSmits: :P
MSmits: was a totally useless paper too
MSmits: did not know that until after i paid 10 for it
struct: you write everything in the same file? o.o
eulerscheZahl: you paid 10 what?
TheBlueBias: bc
eulerscheZahl: 10ETH? that would be expensive
eulerscheZahl: bc? you mean BTC?
TheBlueBias: Hm. Yes
eulerscheZahl: but smits also learned to just ask the author. that way you get the paper for free
derjack: :tada: passed SR. no simulation, just put inputs to NN and got outputs
struct: nice
DomiKo: good job
derjack: it wasnt trained on testcases nor validators*
derjack: need to do something with this steering :x https://www.codingame.com/share-replay/587452449
Musaab: Looking for teammates
Musaab: https://escape.codingame.com/events/t4z-VTs-KDG-mhg/registration?join=Ix6-EQL-cWG-x59
TheBlueBias: Looking for contest
Musaab: For the Fall Challenge
NIgga2: Just started learning C#
Queuebee: is `exec(bytes('砪㴬楦瑬`... allowed in 'shortest mode` clashes?
Queuebee: i keep getting beat by people who do that
TheBlueBias: Yes
Queuebee: REeeeeeeee
eulerscheZahl: is it ok to kick/ban a user just because of the nickname?
eulerscheZahl: NIgga2 please change it
TheBlueBias: Why?
TimothyAlexisVass: I think exec(bytes... should not be allowed :/
eulerscheZahl: are you trolling TheBlueBias?
eulerscheZahl: why not?
eulerscheZahl: who shall prevent it?
TimothyAlexisVass: CG...
eulerscheZahl: that would turn into whack-a-mole
Queuebee: the judge
Queuebee: :D
eulerscheZahl: if you disallow exec in on way, a user will find a similar way to do the same
Queuebee: truetrue
TheBlueBias: Because nigga is different of nigger...
eulerscheZahl: there's even a tool for that: https://clemg.github.io/pythongolfer/
Queuebee: banlist the exact string 'exec(bytes( for python and the next thing to need banning will be 'exec( bytes(' lol
eulerscheZahl: but the intention is clear blaise
eulerscheZahl: or
eval(bytes
Queuebee: yeah
TheBlueBias: I don't understand euler... :(
darkhorse64: Troll
jacek: :no_mouth:
jrke: did names of few multi got changed?
eulerscheZahl: yes
eulerscheZahl: CSB = mad pod racing
eulerscheZahl: Tron = line racing
eulerscheZahl: skynet = death first search
eulerscheZahl: last crusade ? the fall
eulerscheZahl: thor got a new artwork
eulerscheZahl: more to come, stay tuned
eulerscheZahl: also i still want to review your rubik optim :(
adamgosnell: Is it weird that I'm disappointed when the top-rated solutions solve it the same way I did?
TheBlueBias: For one time that I was not trolling...
jacek: oO
Westicles: scrabble seems a million times more dangerous than those other titles
eulerscheZahl: it's on the list too
eulerscheZahl: i suggested scribble. astro wants "words without friends"
let's see what CG takes
Westicles: Hasnobro?
jacek: those with small horses?
Westicles: I guess chuck norris goes as well?
TheBlueBias: Chuck Norris isn't copyrighted, that's the copyright that's Chucknorissed.
eulerscheZahl: i won't leak the complete list now
Westicles: The new masters must be pretty paranoid. Everything besides scrabble seems to be fair use
Westicles: And my avatar is copyrighted, that should go as well
jacek: ban copyrigthed avatars
jrke: looks like the pretty id doesn't got changed
jrke: the last part of link still has old name
Astrobytes: it will change at some point
TheBlueBias: Yup. When they will have found how to change it without broke the entire website. :smirk:
struct: soon all board games are gone
Astrobytes: Nah. Just rename. Cheese, Mothello, Grapethrough, Peckers, Yavalaff etc
Westicles: oops, avatar is trademarked
Westicles: IANAL
Astrobytes: lol
jacek: UANAL? :smirk:
struct: on the board games I do think the names can be copyrighted
Astrobytes: A few of them do have permission from the creators though
Mega_Awesome: how do you take a square root in Java?
Astrobytes: Math.sqrt()
Mega_Awesome: also, is there an easier way to square something than multiplying it by itself?
nathanstephenson: If a problem gives me a normal for(i) loop, why does it time out just iterating over that...
adamgosnell: Mega: the ** operator, I think?
Mega_Awesome: thx and thx
adamgosnell: nathansteohenson: this just happened to me. It's because I was doing too many operations within the for loop.
adamgosnell: I need to ask a question about Shadows of the Knight Episode 1 optimizing, can someone helpful DM me so I don't spoil?
Mega_Awesome: ** does not seem to work
nathanstephenson: adamgosnell: I need all of the operations though, and there aren't many
jacek: Math.pow(x,2)?
Mega_Awesome: ill try it
Mega_Awesome: I think its working
adamgosnell: ** is equivalent. https://www.w3schools.com/js/js_operators.asp
adamgosnell: x ** 2 = Math.pow(x,2)
jacek: he meant java
Astrobytes: Java not js
Astrobytes: x*x is sufficient surely...
adamgosnell: oh. My bad.
Mega_Awesome: x is a bit long and i like things to be somewhat neat
Mega_Awesome: I assume there is a floor function, could someone share that with me?
Astrobytes: We're not a language reference...
Mega_Awesome: oh...
TheBlueBias: rtfm
Mega_Awesome: where could I find this language reference?
Astrobytes: You're familiar with a search engine I imagine...
Mega_Awesome: yes, tho they are often of little help especially when you are looking for something specific
Astrobytes: java manual/documentation/language reference perhaps?
jacek: class Math has many those math things like floor ceil etc.
MSmits: hey, I found that the draw trick is more general than just solving 2 generations upward. You can have whole chains just like ab... I need to figure out how to code it =/
struct: you mean when you solve one node has a draw you need to check it up until root?
MSmits: well depending on the situation of each node that could be true
MSmits: you need to keep track of two properties
MSmits: at minimum a draw, or at maximum a draw
MSmits: when these are both set, it's a draw
MSmits: it's equivalent to alpha == beta
MSmits: when a node has a drawn child it is at maximum a draw
MSmits: when a node has children that all have a draw, the node is at minimum a draw
jacek: solve breakthrough. there are no draws there
MSmits: you could propagate the max/min draw upwards
MSmits: for a few generations, without finding draws
MSmits: and then 5 generations upward, you find a draw because both min and max are set
MSmits: it's like a whole different solver function
MSmits: yeah bt is definitely easier :)
MSmits: or just use standard minmax with ab and TT, that's also easier
MSmits: anyways, i need to struggle with this math a bit and figure something out, then test it on the 7x5 case again to compare
jacek: 7x7 done?
MSmits: 1 starting move is, of the other 3 one is nearly done
MSmits: so no, i am guessing halfway
struct: how much time has it been running for?
MSmits: 48 hrs total i think
MSmits: 24 hr now
MSmits: roughly
MSmits: but this version is solved as a draw, says John. So that's why it's harder
struct: ah right
MSmits: it's already bigger than 7x6 standard c4, but it being a draw makes it worse
ja_fica: My current version of C4 is a UCT NN, now I will test PUCT, get ready to reck me xD
MSmits: maybe it reks us all
ja_fica: I don't think so, I trained it overnight
Mega_Awesome: how do you turn 90.0 -> 90?
TheBlueBias: remove ".0"
MSmits: string[0:length-2] I think?
MSmits: something like that anyways
TheBlueBias: Right
Mega_Awesome: oh yeah, should specify, I'm using Java
ja_fica: thats anoying in shortest mode python.
MSmits: then you're doomed :P
MSmits: well doomed as in i can't help you, maybe there's a java expert
TheBlueBias: Probably better for him you can't help...
Mega_Awesome: also there is a box obscuring part of the chat and there is no obvious way of removing it
ja_fica: I don't know whu my PUCT NN is so bad :(, more training required, better data, different network...
TheBlueBias: A box? Automaton2000 tidy your turtle collection :rage:
Automaton2000: i mean, you have a look at the code and see if it is possible
Mega_Awesome: I'm using a floor function and I think that might have something to do with it
MSmits: Mega_Awesome a box?
MSmits: like a html element?
MSmits: use css positioning
MSmits: j/k, i dont know what box you mean
MSmits: maybe screenshot it
Mega_Awesome: ![Screenshot 2021-10-23 3.20.57 PM.png]()
Mega_Awesome: did that work?
MSmits: eh no, i meant like a printscreen posted to imgu
MSmits: imgur
TheBlueBias: :no_mouth:
MSmits: (avoiding including personal stuff)
Mega_Awesome: I have to post a msg just to see yours
Mega_Awesome: don't know what imgu is
MSmits: the box is blocking the bottom ?
MSmits: https://imgur.com/
Mega_Awesome: dang school restrictions
MSmits: tell me about it
jacek: those teachers eh
MSmits: teachers aren't the one doing it
TheBlueBias: Is there a cat in the box? If yes, is he alive?
MSmits: he didn't say schrödingers experiment was blocking the chat
TheBlueBias: Well. You can't say if it's a schrödinger experiment without opening the box... :3
Mega_Awesome: there is no cat
MSmits: are you say it's both schrödinger's experiment and not schrödinger's experiment until you look?
jacek: no Caturday?
TheBlueBias: Incertitudeception
Mega_Awesome: and if there was a cat it would be both dead and alive
MSmits: very meta quantum
MSmits: Mega_Awesome not after you look
TheBlueBias: Well. You can't measure to property at the same time.
TheBlueBias: tired...
TheBlueBias: *two properties
MSmits: sure you can, depending on which properties they are
MSmits: you can't know both momentum and position at the same time, but you can know other things at the same time
MSmits: like charge and position
MSmits: or momentum and spin
TheBlueBias: Oh.
darkhorse64: MSmits: read
Score Bounded Monte-Carlo Tree Search for draws
TheBlueBias: Free paper?
MSmits: yeah i remember that one from a long time ago. Thanks for reminding me darkhorse64
jacek: Mr. Heisenberg is driving on the free way and a police officer stopped him for speeding. Officer walks up to Heisenberg's car and asks him, "Sir, do you know how fast you are going?" Mr. Heisenberg said "Officer, I have no idea how fast I am going, but I know exactly where I am."
MSmits: thats exactly what i was thinking of
MSmits: haha i know that one, still funny :)
TheBlueBias: :3
MSmits: Pessimistic and optimistic bounds
darkhorse64: Yes, it's free with somewhat readable pseudocode
MSmits: thats the min draw and max draw idea i had
Mega_Awesome: the box is white and it says "Changes done? Run your code when you think you have found the right thrust to win the race."
TheBlueBias: Lel
darkhorse64: You have to change your node to include two status
MSmits: 3 i think
TheBlueBias: A wild tutorial appear.
MSmits: well you can do two if the final status is given by min == max
MSmits: but then to find the final status you need to do a min == max check to see if it is even solved
darkhorse64: yes
Mega_Awesome: yes, it is the tutorial thing-a-majigar
TheBlueBias: Mega_Awesome: Did you simply tried to refresh the page?
Mega_Awesome: yes
Mega_Awesome: it just removed my progress
Astrobytes: Isn't there a skip option?
Mega_Awesome: no
TheBlueBias: Not on CSB one iirc
Astrobytes: Hm. Annoying.
Mega_Awesome: I think I just have to win the race and to do that I must remove .0 from 90.0
Astrobytes: (int)90.0 ?
Astrobytes: or just change the variable to int?
TheBlueBias: How do you get 90.0 in the tutorial? You just have to modify the output string...
Astrobytes: isn't the one after that still a tut?
Astrobytes: I can't remember back that far
Mega_Awesome: I simplified my code and it worked
TheBlueBias: Just push in arena and that's over
Mega_Awesome: I was trying to make check distance with the pithago theorem thing and change speed based on that but all I had to do was put " 70"
Mega_Awesome: smh
Mega_Awesome: sometimes I know too much...
Mega_Awesome: and don't know enough, all at the same time
jacek: oh my
ja_fica: I adjust my exploration rate, now PUCT is good xD
jacek: good for you
Mega_Awesome: ok, so when you floor a sqrt how do you get it to out put x instead of x.0
Mega_Awesome: ?
Mega_Awesome: or how do you just remove the .0 after the fact
Astrobytes: (int)x
Qarnax: hello world
Mega_Awesome: ok, thx
TheBlueBias: https://www.letmegooglethat.com/?q=learn+java
Astrobytes: ^^^^^^^^ this
jacek: kree java!
Astrobytes: shush laddie
Mega_Awesome: Uh oh! This page doesn't want to work.
Invalid link or a processing error occurred.
Astrobytes: are you in school?
Astrobytes: college/uni whatever
TimothyAlexisVass: I work at the university :/
TimothyAlexisVass: Does that count?
TheBlueBias: If you are Mega_Awesome, yes.
Astrobytes: Was talking to the other guy, might have explained his lack of access to the page that TheBlueBias linked
Mega_Awesome: I'm on a Chromebook (quit judging me)
LelouchVC2: i wasn't judging you until you said you had a chromebook
Mega_Awesome: exactly
Mega_Awesome: thats why I included it in the msg
LelouchVC2: because u wanted to be judged?
Mega_Awesome: because I thought I might as well go ahead and tell you to stop judging me
Mega_Awesome: before you even start
TimothyAlexisVass: It's fine if you have a Chromebook
LelouchVC2: if you wanted me to stop judging before i began you should have reordered the sentence
LelouchVC2: Stop judging me, i'm using a chromebook
Waffle3z: can I make the auto-indent stop using 4 spaces instead of 1 tab?
TimothyAlexisVass: People used to think those who had Apple computers were idiots... I remember one guy saying something at work a few years back "Hey you know... I use Apple because I like it when things just work you know?"
LelouchVC2: they aren't idiots?
Waffle3z: also can I make tab stop using 4 spaces instead of tab?
LelouchVC2: i dont believe so waffle
Waffle3z: that's 3head
Mega_Awesome: I am getting the impression that this boss has an advantage...
Zakiyys: its hard
TimothyAlexisVass: Waffle: Where are you trying to replace tabs with 4 spaces?
Waffle3z: you that read backwards
Mega_Awesome: *replace 4 spaces with a tab
TimothyAlexisVass: You want tab instead of 4 spaces?
TimothyAlexisVass: Why? :\
LelouchVC2: The editor on here automatically puts 4 spaces whenever it would normally be just a single tab
LelouchVC2: Python code golf would benefit
LelouchVC2: Shortest mode with python would benefit
Waffle3z: have to copy and paste a tab if I want it to not use spaces. but then enter automatically indents the next line with a bunch of spaces
TimothyAlexisVass: Use spaces instead of tabs.
Waffle3z: no
LelouchVC2: Lmao, what a solution
TimothyAlexisVass: Why not?
TimothyAlexisVass: :D
Mega_Awesome: be miserable
LelouchVC2: dont use an proper editor, code on notepad
LelouchVC2: because why not
TimothyAlexisVass: I think default in editors is 4 spaces ?
TimothyAlexisVass: Or am I quick to change it? :sweat_smile:
Mega_Awesome: I should probably do that essay that I'm supposed to be doing right now...
TimothyAlexisVass: -_
Mega_Awesome: :)
LelouchVC2: I've never seen an editor that requires 4 backspaces to remove a tab before
LelouchVC2: That seems like the wrong assumption to make about editors
Waffle3z: how about 4 left arrows to move back 1 level of indentation
Waffle3z: morally corrupt
LelouchVC2: Its obvious it just adds 4 spaces, it highlights 4 characters when you highlight what should be a tab
Mega_Awesome: He doesn't want to click <- 4 times
Astrobytes: if you're golfing python just replace the tab with 1 space, it's quite simple
Waffle3z: golfing using spaces because spaces are smaller than tabs
LelouchVC2: Its a waste of time, there's no reason the editor shouldn't be counting tabs as a single character to begin with
Astrobytes: if the tabs are spaces then using a single space makes sense
Westicles: write up your tab proposal and print it out and staple it to trees around your neighborhood
Waffle3z: it does count tabs as a single character, it just doesn't put a tab when you press tab
LelouchVC2: sure, but it looks horrific and you have to go back and do it afterwards
TimothyAlexisVass: Well maybe you have a point
TimothyAlexisVass: Then
TimothyAlexisVass: It would be nice to golf with tabs
TheItalianGuyMIO: ahah, would be great :)
TimothyAlexisVass: -_-
LelouchVC2: I'm going to write a 10 page essay on this matter and staple it around westicles' neighborhood
Mega_Awesome: ah HA -Grian
Mega_Awesome: they want to change tah-Hab
Mega_Awesome: If no one gets this that is too bah-Had

https://www.codingame.com/contribute/view/73850e3e96543c0f93523ba5da5ecba23a08
TimothyAlexisVass: I completed this clash...
What's the trick?
TimothyAlexisVass: You are given a number n and a prime number p.
You must tell the greatest power of p that divides n! (where n! is the product of all positive integers⩽n).
Astrobytes: I mean seriously
TimothyAlexisVass: obviously n! was something like 1389472893471238957123895792385612346123897412389751238956237846123897412389712385723569238478923
Astrobytes: don't ask me, I just look at them sometimes to see how ridiculous they are
Astrobytes: (there are good ones, don't get me wrong)
Westicles: reverses are tough to make...
Astrobytes: Title is weird, I get it, but weird. And it's far too easy imo.
TimothyAlexisVass: http://chat.codingame.com/pastebin/7a485d88-11ec-4673-bc99-ba5045de8cc4
TimothyAlexisVass: So does anyone know the trick to this Clash?
Westicles: I just put book titles for reverses since they don't get shown
struct: use ruby
Waffle3z: you already have the number mostly factorized, use that
Astrobytes: ^
Astrobytes: lol struct
TimothyAlexisVass: How are you suppose to find the highest power of P that divides N! when N=100000 and P=997 ? :\
struct: what was the puzzle?
Waffle3z: count the number of times 997 shows up as a factor
struct: can you quote the statement?
TimothyAlexisVass: What do you mean Waffle3z?
TimothyAlexisVass: N! is like...
TimothyAlexisVass: http://chat.codingame.com/pastebin/3956cf92-1d80-457a-afa2-4ca02b745dff
Westicles: 997 is prime so you just count the multiples
TimothyAlexisVass: But N! is like a gazillion digits long
TimothyAlexisVass: oh
Waffle3z: you have the factors already
TimothyAlexisVass: *facepalm*
TimothyAlexisVass: so only have to count the factors that divide by P
TimothyAlexisVass: from 1 to N
TimothyAlexisVass: I'm too tired for this, it's 00:55... I knew that :laughing:

Astrobytes: dude
TechnoBot: can u stop quoting my words pls?
ipsissimus: some people cant handle the neutron style
Astrobytes: you're sailing close to a kick
Astrobytes: Anyway, someone else can do it. I have other things to do right now.
ipsissimus: Python question. for anyone
ipsissimus: can i rewrite the ending sum on 1 line?
ipsissimus: http://chat.codingame.com/pastebin/7353a046-4ab6-44a6-82f3-8ae0d3210414
ipsissimus: actually I know it can be done, but idk how
Dren: probably turn it into a sum(map(function, list))
Dren: where function is a lambda x: int(x,2)
ipsissimus: so print(sum(map(function,list))
ipsissimus: lamda functions always confuse me
ipsissimus: also map here im not sure i understand what its doing
Dren: and you can just unpack the string into a list with [*string]
ipsissimus: hold up
Dren: or [_ for _ in string]
ipsissimus: i thought * only unpacked
ipsissimus: lists
Dren: nah I use it to transform things into lists all the time
Dren: shorter than the list comp from
ipsissimus: ya i seen witchcraft that i cant explain using * and everyone i asked said it was just for list unpacking
ipsissimus: like for gen objects
Dren: yeah to unpack things into a list
Dren: heh
ipsissimus: i need to play with it somemore
Dren: so instead of list(filter) or list(map())
Dren: you can just [*map]
Dren: or [*filter]
Dren: and unpack those
ipsissimus: i need to read map documentation, it seems to have alot of different uses
AllYourTrees: damn [*map] game changer
AllYourTrees: TIL
Dren: yeah because if you chain a bunch of functions like that and sort filter and map in one line constantly calling list() to turn it back makes it real long
ipsissimus: ayy
ipsissimus: i used *
ipsissimus: for once
ipsissimus: http://chat.codingame.com/pastebin/72610ab1-5e1c-42e6-8fb3-944a19903e1c
ipsissimus: inb4 my code is trash and theres a better way
AllYourTrees: did you want tips?
ipsissimus: of course
ipsissimus: i dont want to be trash forever
AllYourTrees: n, r = map(int, input.split())
ipsissimus: that applies int to everything coming from input()
ipsissimus: yes?
AllYourTrees: yep!
AllYourTrees: also recommend checking out list comprehensions
ipsissimus: i have some basic list comprehensions, but i usually write out something as pythonically as possible
ipsissimus: then refactor
ipsissimus: with a comp if i can see one
AllYourTrees: list comprehensions are very pythonic :)
Dren: also that n loop just adds 0s?
AllYourTrees: but that is fair i hear ya
Dren: because you can just write [0]*n
ipsissimus: yeah, because the range function fails with 0 as ending
ipsissimus: i was actually struggling with that
ipsissimus: i know python can let you do str*3
ipsissimus: to get str str str
ipsissimus: but i blanked for when it was an int
ipsissimus: and didnt think to convert
ipsissimus: speed challenge u know
Dren: yeah but ['a']*3 will give you ['a','a','a']
ipsissimus: yeah i see that now
ipsissimus: but it seems just different
ipsissimus: not better
ipsissimus: is it better?
AllYourTrees: depends on what you are trying to do
AllYourTrees: if yuo're trying to do the min code size thing then yes :)
ipsissimus: well by better i mean, faster and less space
ipsissimus: memory*
Dren: well you are looping through a range and adding things one by one
Dren: and this is a simple operation
Dren: I assume it's faster and less memory but I haven't actually benched it
ipsissimus: that makes sense
ipsissimus: i know i should avoid loops if possible
ipsissimus: as they can get quadratic fast
Dren: in the code you sent I would also remove the print from the conditional and just stick it at the end once.
ipsissimus: yes.
ipsissimus: speed challenge isnt good for my brain and optimization
Dren: but that's just a small thing here
ipsissimus: i feel like im developing bad habits with shortest challenge and speed challenge
LelouchVC2: dont worry, you are
ipsissimus: lmao
ipsissimus: ive been indenting with 1 space
Dren: yeah same
ipsissimus: thats bad
Dren: I can't help but want to write that whole thing in one line
ipsissimus: people at my last company would flip their lids if my imports werent alphabetical
ipsissimus: and yet here its like
ipsissimus: you can save 1 char by not putting a space after: if 'k'in list:
ipsissimus: after *
Dren: actually the second for loop isn't needed either
Dren: since you take every number in that range
Dren: you can just create that list with [*range]
Dren: and the conditional can be turned ternary
Dren: once the code gets that small
KayKay1202: Hello
Andriamanitra: or list(range(x)) if you're not golfing
ipsissimus: im going to need an example
ipsissimus: because idk what u just said
ipsissimus: remember
ipsissimus: that was my first time using * and knowing what it was for
Dren: print([0]*n if r==0 else [*range(0,n*r,r)])
ipsissimus: this was someboyd elses solution:
ipsissimus: http://chat.codingame.com/pastebin/dec96859-2db8-4752-a9f4-b340de0b9514
ipsissimus: theyre smarter than me
ipsissimus: and maybe i should ask
ipsissimus: the reason why i incorporated a list at all
ipsissimus: is because the answer was supposed to be space separated
ipsissimus: so the first output was supposed to be
ipsissimus: '0 2 4 6 8'
ipsissimus: and i always run into the problem of having
ipsissimus: '0 2 4 6 8 '
ipsissimus: which has extra space
AllYourTrees: `print(*[i*r for i in range(n)])`?
Dren: yeah that seems to be it
Dren: if you have trailing or leading white space you can just strip
Dren: and if you only need it on one side you can target that too
Dren: like rstrip() or lstrip()
ipsissimus: ah rstrip()
ipsissimus: i forgot
ipsissimus: i tried strip but it obv gets rid of all my spaces
Dren: but you can also just use strip unless you need the space on one side
Dren: for example with justified strings
ipsissimus: i usually get away with it by making a string
ipsissimus: and print(str[:-1])
ipsissimus: but that looks jank to me
AllYourTrees: print(0, 2, 4, 6, 8) will give you space separated values, thats why the print(*[...]) works for ya there
ipsissimus: yeah im trying to always stack my for loops in my prints now
ipsissimus: but most of the time
ipsissimus: theres some curveball
ipsissimus: like i need to do some operation on each element
ipsissimus: so that doesnt work
ipsissimus: thats why im trying to read up on map
Dren: you can map() for that
ipsissimus: ya
Dren: and lambda
ipsissimus: map seems more manageable
ipsissimus: than lambda
ipsissimus: atm
ipsissimus: for me
KayKay1202: i know shes just not right for you
LelouchVC2: She likes more rowdy men
ipsissimus: maybe shes into wrinkles on the brain
ipsissimus: not me
ipsissimus: aerodynamic brain
ipsissimus: smooth
Dren: lambda is just a nameless one line function
KayKay1202: i can treat you better than she can and any boy like you desevese a women
KayKay1202: so i know that u wastin time when you could be with me instead
ipsissimus: lamda for smooth brain? :grinning:
Dren: def add(a,b): return a+b
is the same as
lambda a,b: a+b
ipsissimus: i just have to remember lambda syntax
KayKay1202: Another Day please into night Fall and you're not here to get me through it all i let my guard down and then you pulled the rug that he was getting kinda used to be someone you loved
Waffle3z: I submitted a bot for counting tictactoe at wood 3 and walked away and now I'm wood 1, I missed all the wood 2 games
KayKay1202: hey guys
Dren: hey kay
KayKay1202: dren do yuo type or read fast
C26_1: um
C26_1: I just want to ask a question
Thorcode: ?
C26_1: Do we must say something naturally or we just need grammatically correct sentence?
C26_1: I mean we still communication with each other when become a coder right?
Thorcode: yep
ipsissimus: bad grammar? straight to jail
KayKay1202: Anybody do anything fun today
Ruskin: Raining here, still in lockdown. More a of a day for clashes and work than anything else
ProCoder03: is NZ still in lockdown ??
KayKay1202: WHAT IS NZ
ProCoder03: new zealand
KayKay1202: OH I AM STUPID
ProCoder03: struct can we block person in private chats ??
struct: dont think so, who is it? Can you pm me?
struct: ProCoder03
KayKay1202: ME
KayKay1202: IT WAS ME
struct: Well can you stop pming people for no reason?
Ruskin: Auckland is still in lockdown, until we hit 90% vaccinated
Thorcode: can I block pp in private? struct
ProCoder03: nope
Thorcode: no
Ruskin: I think we're about 89% rn
ProCoder03: Ruskin sorry for that
Thorcode: whyyyyyyyyyyyyyyyy
struct: Thorcode check pm
Ruskin: Meh, used to it by now
Ruskin: And we had a solid- 18 months without any restrictions, so it could have been a lot worse
ipsissimus: you know how some problems give you a var assignment that you never use? how do i get rid of that input()
ipsissimus: or throw it away
ProCoder03: the irony is here, we are just some 57% vaccinated single dose, and people are back to normal
ipsissimus: for shortest code challenge
Ruskin: You just have to input(), but do nothing with it
Ruskin: No way round that afaik
ipsissimus: ok ty
ipsissimus: idk how u did the last one in 57chrs
ipsissimus: im at 75 and trying to do all the tricks i know
Ruskin: Hey, at least it wasn't Ruby. I can never understand anything that anyone does in Ruby!
ipsissimus: ye, and they always share
ipsissimus: to rub it in
struct: Ruskin I think new Zeland is at 57%
struct: 58.4
struct: https://ourworldindata.org/grapher/share-people-fully-vaccinated-covid?time=2020-12-27..latest&country=DEU~JPN~PRT~SGP~ARE~USA~GBR~OWID_WRL~FRA~ISR~European+Union~CHN~NZL
struct: 87% on portugal :)
ProCoder03: he is in auckland
Westicles: definition is changing though
ProCoder03: maybe the city has 89%
struct: ah ok
struct: Yeah doesnt seem very effective
struct: we are still having 1000 daily cases
ipsissimus: ruskin ive seen u do it twice now, what is the behavior or print(end) without a initial parameter?
Westicles: you could die in a fire in the US and they put down covid
ipsissimus: i only know print(x,end)
ipsissimus: yeah i second what westicles said
Ruskin: I think we're 89% on first doses. But we've only just recently had out big vaccine push, so second doses will go up rapidly in a week or two
ipsissimus: flu taking a vacation this year
Ruskin: I just use print(end=) so you don't get a carriage return
ProCoder03: wait India is only at 20% :confused:
Ruskin: Means you don't have to build a list and then join() it
ipsissimus: ok i understand
bminnix: No no. Flu is down because everyone is so precautious of COVID :rolling_eyes:
ipsissimus: my friend died in a motorcycle accident. official cause of death: you guessed it
bminnix: Sorry to hear about your friend
ipsissimus: :/
bminnix: Where I live people have just been going on about their lives for a while now.
bminnix: Most not vaccinated, some are. Most don't wear masks, some do.
ProCoder03: Well in our country, its back like 2019... except for a mask at chin :joy:
Westicles: they'll give us a break for a few months, then next year smallpox will be the big thing
Westicles: or maybe ebola. I always like that one
ProCoder03: nah.... China has a new variant with it
KayKay1202: ipsissimus at least ur not the only persons whos friend died mine died of cancer
Ruskin: Westicles, smallpox was eliminated. The vaccine worked
Westicles: https://www.fda.gov/emergency-preparedness-and-response/mcm-issues/smallpox-preparedness-and-response-updates-fda
ipsissimus: the existence of smallpox implies the existence of largepox
ipsissimus: and normalsizepox
Ruskin: Not sure what your point is. Smallpox was eradicated because enough people got vaccinated. I guess you're worried that someone could re-release smallpox on the world?
Westicles: big pharm doesn't spend hundreds of millions on a new vaccine 'just in case'. they made it, they'll find a market
Ruskin: Well maybe, maybe not. I hope not. Meanwhile, I'm worried by people using arguments like this to minimise the threat of our current pandemic, and somehow argue against the simple mitigation measures (masks, vaccines) that we should be taking
Westicles: I don't think we are going to agree, so I'll stop here :P
Ruskin: Yeah, me too, I'm off to do some clashes. See you there?!
bminnix: Aww man, I was hoping to see you guys finish that conversation, lol.
bminnix: Just sitting in here like, :eyes:
bminnix: :popcorn:
KayKay1202: lol
bminnix: The one thing found interesting was to see how people in the "We should be wearing masks to protect everyone else" camp get their vac and be like, "I know I can get it, I know I can spread it. It won't make me as sick so I don't need to wear a mask".
bminnix: And the government endorse that mindset by permitting vaccinated people to go maskless while enforcing masks on unvaccinated people.
Ruskin: Which government does that bminnix?
KayKay1202: i want a boyfriend so put on me im lookin for a person who can take my heat i need a rude boy tell me somethin sweet at the same tie
Broso56: hopefully it goes well!
