Downgoat

@LegionMammal978 you are spy????? That explains why your avatar was blank

LegionMammal978

@Downgoat ;)

flawr

@LegionMammal978 What do you mean by even split?

LegionMammal978

@flawr As in, half will be greater and half will be less

TùxCräftîñg

20:02

@Downgoat his invisibility field failed

LegionMammal978

^

Downgoat

@TùxCräftîñg wat @LegionMammal978 pls share invisibility technology

TùxCräftîñg

and now i use vim

Downgoat

will be very helpful to conceal my secret stash of tin cans from the other goats

@TùxCräftîñg :D \o/

LegionMammal978

@Downgoat

El'endia Starman

For the [k/N,(k+1)/N)x[l/N,(l+1)/N) for k,l=0,1,2,...,N-1 part, I would suggest using i,j as indices instead of k,l.

TùxCräftîñg

but idk how to select a text ._.

but i know how to bork my vimrc!

LegionMammal978

@Downgoat Sorry, I was trying to say that

flawr

@LegionMammal978 But you do have to calculate the mean of those again, as you are calculating the mean/median per class

LegionMammal978

@flawr true

flawr

20:03

@El'endiaStarman Why not I,l

=P

Downgoat

@TùxCräftîñg v<motion>

flawr

@El'endiaStarman Thanks for the suggestiosn so far

Downgoat

@TùxCräftîñg ;_;

TùxCräftîñg

it's pretty easy with vim ;_;

@Downgoat so TIL

Downgoat

another reason I dislike python: ^C does't exit repl, I have to do ^D

TùxCräftîñg

20:05

@Downgoat like bash

quartata

@Downgoat Doesn't work in irb either

Or any repl I know

El'endia Starman

@Downgoat So, when you stop an infinite loop with ^C, it should also exit the REPL?

flawr

@HelkaHomba The non-commutativity would be a pain in the a*ss when it comes to physics.

TùxCräftîñg

^^

Downgoat

:/ works in node repl and JS repl

idk I'm just used to using ^C to stop program

TùxCräftîñg

20:06

@Downgoat ^D is the standard way to exit a repl

Downgoat

@El'endiaStarman no it should stop the loop. when you press it at an empty prompt it should exit

@TùxCräftîñg really? TIL

still ^C should stop the program

El'endia Starman

@Downgoat What if you're spamming ^Cs to try and get it to stop now?

TùxCräftîñg

^

El'endia Starman

Like on C9... -_-

Downgoat

@El'endiaStarman if you are spamming "STAHP PYTON PLS" (i.e. ^C) it should exit

TùxCräftîñg

20:08

@Downgoat no, the spam is "STAHP DIS INFINIT LUP"

El'endia Starman

@Downgoat That'd be immensely frustrating behavior, though.

Downgoat

node requires you to press ^C twice

on an empty prompt

LegionMammal978

@Downgoat that's correct

El'endia Starman

I used to be (like, years ago) quite annoyed at Python IDLE's behavior where closing a hung REPL would also close the source code file window.

Ye, I spilled coke on my laptop :P — betseg 9 secs ago

this is why you eat tin cans not drink out of them

TùxCräftîñg

i dont drink coke

only water

but water have the same behaviour on laptops :/

Downgoat

:/

El'endia Starman

@flawr: Regarding your decision trees challenge, the first half seems good. Second half awaits an actual visualization...

ven

@TùxCräftîñg O_ô

TùxCräftîñg

@ven ಠ_ಠ

ven

M'enfin!

TùxCräftîñg

?

ven

C is easy to type on mobile though.

It's a pain when I'm writing Jelly on my phone...

TùxCräftîñg

@ven are you seriously speaking?

flawr

@El'endiaStarman You mean of the given example?

ven

20:14

Uh, comparatively with Jelly, very much.

El'endia Starman

@flawr Preferably, yes.

TùxCräftîñg

@ven the android keyboard is really bad

quartata

Pytek quine sometime in the future

TùxCräftîñg

quartata

<...> is lambda

Downgoat

20:19

@quartata how 2 get args?

quartata

@Downgoat <x:...>

flawr

@El'endiaStarman added

Downgoat

ok

flawr

Now I just need to program it myself to make some exampls=)

Downgoat

20:33

@LegionMammal978 status on rationals? :3

LegionMammal978

@Downgoat still procrastinating on tests

Downgoat

it's OK. coverage is now so shitty no ones gonna notice if it goes down

quartata

Coverage is 73%...

that's not that bad

Downgoat

@TùxCräftîñg ಠ_______________ಠ

TùxCräftîñg

?

Downgoat

20:36

you said python is life

ಠ_ಠ

TùxCräftîñg

because it's true ¯\_(ツ)_/¯

Downgoat

TIL life is death

TùxCräftîñg

so we are all dead ಠ_ಠ

Zwei

ugh, all these weird symbols are boxes to me because I haven't prioritized downloading a font for everything

TùxCräftîñg

@Zwei dejavu fonts are excellent

Zwei

20:38

like, the only font that I have actually installed is hack

Downgoat

omg there's a babel unicode regex package!!!!!

TùxCräftîñg

\(ツ)/

quartata

@Downgoat ermahgerd the perfect combination of words for gaot

Downgoat

TIL there's also a babel static typing package

TùxCräftîñg

@Downgoat ಠ_ಠ

Downgoat

20:40

?

TùxCräftîñg

static typed js

Downgoat

:/ \p{L} isn't woking ;_:

ven

tyepskrippt

TùxCräftîñg

;/-/

ven

@Downgoat :_;

TùxCräftîñg

20:41

@ven typescript is bad

ven

uhhhh.

not even going to engage in this discussion.

TùxCräftîñg

really bad

quartata

@TùxCräftîñg I think most everyone who uses JS in production at minimum uses "use strict"

ven

really not going to.

TùxCräftîñg

@quartata yeah, everyone use "use strict" but static typed js is a abberation

Zwei

20:43

I just avoid javascript as a whole

El'endia Starman

@flawr Looks great.

Downgoat

@TùxCräftîñg ಠ_ಠ static typing is great

El'endia Starman

@flawr Make sure to include one where red dots are surrounded by blue dots. Unless that sort of scenario will never happen.

TùxCräftîñg

@Downgoat static typing is great but in js it's a abberation

because js is illogic

Downgoat

you have no idea how much suffering and wasted days I would of saved from debugging implicit casting and allowing any type to go through

TùxCräftîñg

20:44

@Downgoat ._.

ven

@Downgoat static typing is amazing

and TypeScript is nice.

Downgoat

^

ven

though its inference features are lacking

Downgoat

@ven former is true latter is false

TùxCräftîñg

xD

ven

20:45

still no argument

flawr

@El'endiaStarman The wildest things can happen.

LegionMammal978

lol, like 800 people on a stream (including me) are DDoS'ing a scammer's IP

TùxCräftîñg

21:01

G0=G,s+GW=+

Somehow feels like I could find something better to get 2 elements from a string...

TùxCräftîñg

idk how to split the screen with cmder ;_;

flawr

@El'endiaStarman Somehow I think it would look better if you could see the actual "decision lines"

But that would probably considered unecessary fluff.

El'endia Starman

@flawr The final visualization? Yeah, it probably would. (Look better and be "fluff".)

flawr

If Piet Mondarin only lived 200 years later I'd become famous now.

@El'endiaStarman But this fluff really looks good =/

El'endia Starman

@flawr It does... ;_;

Put it in as a non-scoring bonus.

flawr

21:15

But it would take quite a few paragraphs to specify how those borders should be calculated=/

Dennis

The thread is rather old, so I'll just leave this here so it gets some attention.

A: Choosing outputs for challenges

Yes, you can choose the output. In fact, this is already what we do. A full program that prints to STDOUT will also terminate with a certain exit code, and exit codes are a valid form of output. Per consensus, programs are allowed to terminate with an error after producing the correct output,...

ven

to get an array with first and last element, I could actually replace-but-first-and-last... mmh

"hey you miley"S/{:G,3>G[(\)\;]G,s*G?}%S*

worse than before :[

So I tried signing up for cloud 9 and before I got started they already want my credit card

imagine how that would be in real life

Dr Green Eggs and Iron Man

chat.stackexchange.com/…

Mᴀʀs Uʟᴛᴏʀ

21:53

@uoɥʇʎPʎzɐɹC wat

@uoɥʇʎPʎzɐɹC You don't need your credit card details, if you can't figure out how to not fill them in just login using GitHub

uoɥʇʎPʎzɐɹC

@MᴀʀsUʟᴛᴏʀ it's required

it literally says "your credit card detaisl"

and I logged in with github

El'endia Starman

@MᴀʀsUʟᴛᴏʀ This. My C9 account is linked with my GitHub account. No need to enter credit card details!

uoɥʇʎPʎzɐɹC

@MᴀʀsUʟᴛᴏʀ

@El'endiaStarman really? I started with clicking the octocon

Mᴀʀs Uʟᴛᴏʀ

@uoɥʇʎPʎzɐɹC Then is there any way to skip the payment dialog?

uoɥʇʎPʎzɐɹC

@MᴀʀsUʟᴛᴏʀ nope

@El'endiaStarman help!

how'd you do it?

Mᴀʀs Uʟᴛᴏʀ

21:55

@uoɥʇʎPʎzɐɹC How did it even appear

uoɥʇʎPʎzɐɹC

@MᴀʀsUʟᴛᴏʀ GitHub > Authorize > fill in other details > boom credit card

El'endia Starman

@uoɥʇʎPʎzɐɹC I don't remember - I did it a few months ago.

Mᴀʀs Uʟᴛᴏʀ

@uoɥʇʎPʎzɐɹC Don't think I needed to fill in any other details

uoɥʇʎPʎzɐɹC

even heroku doesn't need credit card

@El'endiaStarman can you try and register a new account and tell me how you did it?

@Downgoat why do you like goats so much?

what did goats do to you?

threaten your family?

Mᴀʀs Uʟᴛᴏʀ

@uoɥʇʎPʎzɐɹC what are you talking about, Downgoat is a goat

uoɥʇʎPʎzɐɹC

21:59

a goat named vihan

tl;dr HALP HOW DO I SIGNUP CLOUD 9 I NO HAZ CREDIT CARD HALP

Mᴀʀs Uʟᴛᴏʀ

@uoɥʇʎPʎzɐɹC screenshot without personal details?

there should be a skip dialog somewhere, unless you tried to do something that you need to pay for

uoɥʇʎPʎzɐɹC

no skip dialog

nothing I need to pay for

quartata

What site are you actually at?

uoɥʇʎPʎzɐɹC

and they mentioned free plan

c9.io

@MᴀʀsUʟᴛᴏʀ

Mᴀʀs Uʟᴛᴏʀ

@uoɥʇʎPʎzɐɹC sorry, at school, can you upload to stack exchange imgur?

uoɥʇʎPʎzɐɹC

22:04

@MᴀʀsUʟᴛᴏʀ people are still in school in the summer!?!

Zizouz212

@uoɥʇʎPʎzɐɹC I am.

quartata

I don't think you logged in via GH

Zizouz212

In fact, I've got exams in the coming week :/

uoɥʇʎPʎzɐɹC

@quartata first thing I did was click the github logo

try doing it yourself :/

Mᴀʀs Uʟᴛᴏʀ

@uoɥʇʎPʎzɐɹC I always do that, no credit card details needed

quartata

22:07

After the GH authentication popup you shouldn't get anything else

uoɥʇʎPʎzɐɹC

not for me

it asks for username and stuff

probs cause my username has caps in it

Mᴀʀs Uʟᴛᴏʀ

@uoɥʇʎPʎzɐɹC ???

uoɥʇʎPʎzɐɹC

@MᴀʀsUʟᴛᴏʀ c9 doesn't allow usernames with caps

but I've run out of alt emails on GH

uoɥʇʎPʎzɐɹC

waaaaaaat

esolangs

esolangs everywhere

quartata

22:19

That's just CJam

ven

and me being esobad at it

at least I'm done with my little set of challenges.

I'm sure I'm in the minority in that I care about the languages, not about the challenges...

quartata

What was the challenge that was for? Maybe I can help a bit

El'endia Starman

...so, I have this Google Doc that I use to document tasks that I did during the day. I just wrote "Finish archive-binging CommitStrip", and "Finish" was underlined with a red squiggle. Add an 'n' to make it "Finnish" and it goes away. What the heck, Google.

quartata

wa

uoɥʇʎPʎzɐɹC

@El'endiaStarman one time the google autocoreect made me go into an infinite looop

quartata

22:38

@El'endiaStarman oh dear

GamrCorps

@El'endiaStarman Finish is a present tense verb and it deems the rest of the sentence as a different tense, so it gives you the red line

Mᴀʀs Uʟᴛᴏʀ

@GamrCorps ?

GamrCorps

either that or Finish isn't in your dictionary

El'endia Starman

I added "Finish" to my dictionary.

GamrCorps

huh

weird

Mᴀʀs Uʟᴛᴏʀ

22:43

@El'endiaStarman refresh maybe?

El'endia Starman

Also, I thought it was primarily Microsoft Word that pointed out grammatical errors, and with a blue squiggly line too.

@MᴀʀsUʟᴛᴏʀ Too late now.

quartata

@GamrCorps But it's imperative

GamrCorps

oh yeah... huh...

quartata

Yeesh, if a spell check is going to go out of its way to be helpful at least be clever

quartata

23:03

Just clicked on a SO Jobs ad and Compiz immediately hanged. Fun.

dorukayhan

oh hai

Dennis

23:16

@quartata Compiz is the main reason I ditched Ubuntu. The best part is that the bug report app usually froze right after Compiz crashed.

quartata

Yeah, Compiz is shit. I can't wait until I get around to installing Arch and replacing it with OpenBox or Sawfish

uoɥʇʎPʎzɐɹC

so inactive

quartata

There was an interesting job advertised too and I can't find it now. Damn.

@uoɥʇʎPʎzɐɹC ?

uoɥʇʎPʎzɐɹC

the chatroom

Dennis

Typical Sunday.

My weapon of choice is KDE.

El'endia Starman

23:21

Hey, it's nice to have a quiet time in TNB every now and then...

quartata

KDE 4 is bad. KDE 3 was amazing

Dennis

That's just romantizing the past.

quartata

Really not

Dennis

And 4 isn't the current version anyway.

quartata

Wait, what?

Dennis

23:23

KDE 5 (or Plasma 5, really) is the current version.

quartata

Hm, looks a little better

Dennis

The initial releases of KDE 4 were supposedly bad (I haven't used them), but I'm very happy with my current version. It's stable, responsive, and as a sucker for settings, I couldn't be happier. You can configure everything.

uoɥʇʎPʎzɐɹC

do you know the most evil C++ statement?

#define true (rand() > 10)

Dennis

Pretty sure that doesn't beat wiping the hard drive.

quartata

The evilest part about it is that in an actual C software project it wouldn't work since C convention usually calls for TRUE

Mᴀʀs Uʟᴛᴏʀ

23:31

@uoɥʇʎPʎzɐɹC why not 0?

uoɥʇʎPʎzɐɹC

@Dennis but it's slower and harder to fix

Mᴀʀs Uʟᴛᴏʀ

@uoɥʇʎPʎzɐɹC how? you can just delete that statement

uoɥʇʎPʎzɐɹC

@MᴀʀsUʟᴛᴏʀ not if its buried in the stdlib

Mᴀʀs Uʟᴛᴏʀ

@uoɥʇʎPʎzɐɹC just get a working stdlib

also, TIL why there's a website just for bad autocorrect

@uoɥʇʎPʎzɐɹC you can just recompile the stdlib

uoɥʇʎPʎzɐɹC

...

ahhdarnit it's just a joke

Mᴀʀs Uʟᴛᴏʀ

23:39

Yeah, but I'm just saying it's not very evil at all

quartata

Ugh, this error makes no sense

def get_stickies(bot):
  stickies = ""
  for sticky in EntityIter("tf_projectile_pipe_remote", exact_match=True):
    if not sticky: continue
    owner = sticky.get_datamap_property_char("m_iTeamNum")
    if ord(owner) == bot.team:
      pos = sticky.get_datamap_property_vector("m_vecOrigin")
      stickies += str(pos.x) + ";" + str(pos.y) + ";" + str(pos.z) + ","

  if stickies:
    return stickies[:-1]
  else:
    return ""

Honest question does anyone see any possible branch where this returns None

It can't and yet I'm getting a can't cast NoneType in the send_input

how

LegionMammal978

@quartata Try adding some prints for debugging

quartata

@LegionMammal978 I would normally do that but print does something that causes SourcePython to spawn too many threads and segfault

LegionMammal978

@quartata idk, write to a log file or something

quartata

This is why the controller has taken 2 weeks

Mᴀʀs Uʟᴛᴏʀ

23:46

interesting link

quartata

@LegionMammal978 I think there's a core.echo_console but considering this gets called every 66 milliseconds it wouldn't be too surprised if it caused it to blow up too

When an error gets thrown it happens too

My guess is that print keeps the thread alive long enough for the next tick's threads to spawn

LegionMammal978

You sure that function is returning None?

quartata

Unless it magically morphs into None:

def send_input(player, enemy):
  player_obj = player.player
  enemy_obj = enemy.player
  player_info = player_obj.playerinfo
  enemy_info = enemy_obj.playerinfo
  player_nades = get_nades(player)
  enemy_nades = get_nades(enemy)
  player_stickies = get_stickies(player)
  enemy_stickies = get_stickies(enemy)
  player_clip = get_clip(player)
  enemy_clip = get_clip(enemy)

  player.program_pipe.stdin.write(bytes(
    str(player_info.origin.x) + "\n" + str(player_info.origin.y) + "\n" + str(player_info.origin.z) + "\n" +

The error occurs at the player_nades + "\n" + player_stickies + "\n" +

LegionMammal978

> program_pipe.stdin.write

wat

quartata

I'm writing it to another process

LegionMammal978

23:51

You sure it's not in player_nades?

quartata

player_nades?

That's a variable

LegionMammal978

(Also, that Python 2 or 3?)

quartata

Oh, you mean get_nades?

LegionMammal978

@quartata yep

quartata

That's identical to get_stickies except for a different entity name

Oh, although... it does have a flags thing

  nades += str(int(not nade.get_datamap_property_ushort("m_fFlags") & 1)) + ","

That wouldn't cause this though

@LegionMammal978 3

OK, a sacrificial print reveals them to be empty strings

LegionMammal978

23:56

@quartata what I thought

quartata

But that shouldn't cause problems....

I expect it to output some empty strings

"" + "asdf" works fine

Actually, wait a second...

what the fuck? It works now?

Oh, oops.

No, it totally works

What on earth
