fun wikipedia find

I think there is something not quite right here

wow my fill method took up half the time of the unit tests :P

hmm isinstance is taking up 10% of runtime now should i be optimizing it

c'mon NMP, you can do this!

Q: Generate chord charts for ukulele

Your task is to write a function which outputs a ukulele chord chart in the following format for a given chord symbol. For instance, for input "G7", it must output: G C E A --------- | | |#| | --------- | |#| |#| --------- | | | | | --------- | | | | | --------- | | | | | --------- It must...

Does anyone know if this is bad practice? (answering my own question with a solution that will clearly not be winning)

@MDXF It's fine

Okay

1:01 AM

why do people get mad over a wrong definition

because wrong definitions lead to wrong usage

but if i define that usage, the definition shouldn't matter

In the case of MW it goes both ways, turning it into a positive feedback loop of language misues

You mean, you define addition on integers as taking the absolute value of a normal sum? This can get confusing - not to mention that this makes your addition not a group action

then why even have definitions?

to standardize usage of terms.

1:07 AM

i guess that did bite me somewhat

Destructible Lemon

am I the only one who gets annoyed at the fact that you can assign to lists from inside functions?

unclear. What language?

Alternative medicine

Alternative medicine — or fringe medicine — includes practices claimed to have the healing effects of medicine but which are disproven, unproven, impossible to prove, or are excessively harmful in relation to their effect; and where the scientific consensus is that the therapy does not, or can not, work because the known laws of nature are violated by its basic claims; or where it is considered so much worse than conventional treatment that it would be unethical to offer as treatment. Alternative therapies or diagnoses are not part of medicine or science-based healthcare systems. Alternative medicine...

@JanDvorak python

I guess I'll just provide the args with a shallow copy [:]

it doesn't have lists within lists so it should be fine

perhaps clone your argument within the function instead

Destructible Lemon

yeah it doesn't matter. also I was considering using tuples and adding them but that seems bad

what should I do if a program attempts to discard an already discarded item?

1:17 AM

does it fail when it does?

@DestructibleLemon

Destructible Lemon

I guess it can just assume that it places it in the dungeon?

or maybe it commits suicide

@NathanMerrill you know KOTHs right? what should I do?

best way to check if an item is a list in python?

I tried searching SO, but it just gives best way to check if an item is in a list

type(item)

Destructible Lemon

hmmm

isinstance(var, list)

will return true or false

@DestructibleLemon

Destructible Lemon

k

at least, in python 3

Destructible Lemon

1:44 AM

yeah, I plan to use python 3

@KuanHulio type(var)is list is golfier

Destructible Lemon

yeah but are we really going for golf? I don't know, but you guys figure it out

@WheatWizard type(var)==list

if you are going to be like that

@DestructibleLemon I didn't know you were allowed to do that

Destructible Lemon

Q: How can I golf this program to flatten a cube?

I am attempting an answer to this question and, while having finished the actual code, I am having trouble minimizing it. I hope that this is on topic but I'm not sure. My code is currently a whooping ~4000 bytes long and is in Python. Any tips would be appreciated. However, please refrain from ...

people wanna help with my koth?

@WheatWizard its more pythonic to do is than ==

1:57 AM

@NewMainPosts doesn't appear to work

Well then I have one hell of a golf

@WheatWizard ?

lol they used u for two diferent things

@ASCII-only If the code doesn't have to work it can be done in zero bytes

@WheatWizard true

ewww, global variables. I forgot those existed

2:01 AM

@EriktheOutgolfer Fixed

I hardly get any votes or responses on sandboxed posts, then a bunch when I actually post them to main (positive and negative responses). I really like this challenge, I think it's pretty clear and easy... should I post it?

And should I use the ascii-art tag or not?

No

does it use ascii

@KuanHulio Optionally

@WheatWizard To which

don't use ascii-art

2:07 AM

Okay

I guess since it's not really art and ASCII is optional anyway I shouldn't

Python 59 bytes (*nix terminal):lambda x:"\033[31m"+"\033[37m"*(x<200)+"NO\033[31m VACANCY"

Exactly, it will take people 30 seconds to solve

Feels like the kind of thing that goes viral tbh :P

Might be golfable

btw, you can save a few bytes by using \e in the place of \033

should work if you're on *nix

Doesn't work for me

2:08 AM

Oh okay

I am on *nix

Might just be a C thing

It doesn't work in Java either

Ok might be then

All right

Is it okay to post?

I can probably preassign \033[31m though

2:09 AM

Yeah

Man, that will look pretty cool... a <59-byte pre-golfed answer in 10 seconds flat

I actually can preassign \033[

How many bytes is it now

which is kind of cool

Aw snap the title is too small

(No) Vacancy is 13 bytes

Title requires 15

59 is still the shortest

preassigning doesn't save bytes

2:12 AM

Almost fixed:

you log out very carefully

and I don't want to switch browsers

how about

user165474

much better

@MDXF Can we assume a default color of the terminal?

user165474

@KuanHulio what tf is this

@WheatWizard Your program must use your shell/terminal/IDE's default background color.

Destructible Lemon

probably something about emag eht

2:15 AM

you dont know what binary is?

user165474

actually don't tell me

user165474

i want to figure it out myself

@WheatWizard Additionally, If T ≤ 200, the letters of NO must be printed in your shell/terminal/IDE's default foreground color.

Oh ok

that makes things easier for me

Yeah I figured it would

user165474

2:16 AM

"log out very carefull"?

@HyperNeutrino It's a popular phrase

congrats

When someone asks how to do something obvious, others will often say "very carefully"

(no offense :P)

see he gets it

user165474

2:16 AM

did you just assume my gender

user165474

(cc MD XF ;P)

My dad used to pull that on me all the time when I would ask obvious crap about C

@HyperNeutrino How so :P

did YOU just assume MY gender?

user165474

map(lambda x:chr(int(x,2)),s.split())

Oh @KuanHulio assumed mine

Luckily for him I'm a dude

@MDXF Did you just assume Kuan Hulio's gender?

Destructible Lemon

anyway, wanna hear a crappy joke?

Oops :P

How about Motel sign challenge: (No) Vacancy

Or just Motel challenge: (No) Vacancy

Are either of those catchy enough?

Actually, I think I'm gonna go with Vacancy or no vacancy?

Yeah

no this is patrick

user165474

ooo interesting

Yeah

Destructible Lemon

2:20 AM

should be (NO )?VACANCY

What should I name it though

@DestructibleLemon That's still two bytes too short

user165474

though i personally would generalize it more, it seems interesting

They aren't letting us golf our titles :(

@HyperNeutrino How so?

when people get mad over a small definition so you have to make your own word

user165474

@DestructibleLemon 0/10 the "NO" is always there

Destructible Lemon

2:20 AM

(No v|V)acancy

@DestructibleLemon Nah because it's all caps anyway

But all-caps titles are annoying

You know what, I'm just gonna post it and change the title to something catchier later

if necessary

I had a sandboxed challenge named "HE COMETH NOT"

Destructible Lemon

no vacancy for noveau tech

or something

user165474

@MDXF i think the part about checking if i > 200 doesn't seem any more interesting than just taking it as a boolean, and then it mostly just reduces down to finding a way to output colors. but idk looks good to me

@WheatWizard Nice job

@HyperNeutrino I think taking it as a boolean is a lot easier and a lot less original

Also if we're calculating the number of taken rooms, why would the input be a boolean?

2:23 AM

That might have been my Fastest west in the west ever, I think I got it in less than 30 seconfs

It was in 3 seconds

No joke

"That might have been my Fastest west in the west ever, I think I got it in less than 30 seconfs"

Well that's what the system says

> Fastest west in the west

no, he meant fastest gun in the west

2:23 AM

>30 seconfs

@MDXF who needs guns when you have wests

3

Accurate :P

i just need my wests in 30 seconfs

SECONFS = StackExchange Configuration Files

:D

Destructible Lemon

everyone use seconfs from now on

2:26 AM

I like how WheatWizard hasn't even corrected himself yet :P

Destructible Lemon

maybe... he did it on purpose

I guess it's possible

Highly unlikely though

user165474

~~did you just assume wheatwizard's gender~~ maybe i should stop

I did the Fastest west in the west on purpose, because I've done that before, but seconfs was a accident

I thought the consensus was to change it to just the title

well deleting it is nice

user165474

especially for people on the app

user165474

for me it makes no difference

user165474

2:31 AM

same with wheat wizard

sandbox 2.0 when?

o0 you use the app?

user165474

no

user165474

i use it to get updates though

user165474

and then when i get a notification i go to a computer and open the site

Destructible Lemon

2:33 AM

ok, so say I have two items, that I want to do an operation on in a loop

but the order is variable

so far I added an if statement at the start, but is that the best way?

user165474

example?

Destructible Lemon

just a second

wait, I just realised a better way to do this

user165474

ah ok

user165474

can I see the original/the better version though?

Destructible Lemon

to be honest they aren't really related and I never finished the first way

user165474

2:42 AM

ah ok

@HyperNeutrino Whats going on? I'm confused as to why I was mentioned.

user165474

on the website it makes no difference to you whether or not a post is deleted because you have >2k

Oh yes, that is true, The only difference is that they are red.

user165474

yes

user165474

true

2:46 AM

@HyperNeutrino Do people actually use that? o_O

user165474

I have it on my phone...

user165474

But I don't use it often.

user165474

I usually just use it so I know when I get a notification :P

I don't even have a phone :(

(i mean duh I've got a work phone but not a smartphone)

Well, I do have it on my phone too, but I wouldn't dare using it for anything.

Posted a challenge from it to get a hat, but that's about it.

2:48 AM

is lambda{|x|...} really the shortest way to make a ruby lambda?

You don't need escape sequences for unprintable bytes.

@WheatWizard I could beat both of your solutions but I'm pretty sure it's bad practice to bomb your own challenge immediately

user165474

Isn't ->something correct?

Destructible Lemon

CMC: return a truthy value (if x: print(truthy)) if a float is not an integer

@HyperNeutrino yes thanks

user165474

2:50 AM

ooo ok

@DestructibleLemon What does CMC stand for?

user165474

Ah

Thanks

(@DestructibleLemon ninja'd)

2:51 AM

@DestructibleLemon what do you mean?

what KoTH should you make?

@Dennis What is this? I'm not sure what you are suggesting

Destructible Lemon

whoops, accidentally a word

@MDXF In ruby and python or in another language?

In C

@WheatWizard Replacing \033 and \e with actual ESC bytes.

2:52 AM

Oh good thinking

Destructible Lemon

@NathanMerrill I mean, if a bot tries to discard an already discarded item, should it be suicide or should it default to placing in the dungeon. I decided to be lenient so far. should I not be?

@Dennis I suggested that, he said it didn't work

Ohh for Ruby

hard to test though :p

nvm

What is the esc byte?

oh 27 nvrmnd

2:54 AM

@DestructibleLemon always remove submissions that don't follow the rules

Destructible Lemon

well, if I do it this way, they follow the rules

@WheatWizard Do either of your solutions print a newline?

Python 3 doesn't like non-UTF-8 code, but Ruby might actually let you get away with CSI bytes.

however, is the KoTH already posted? If so, don't change your rules

@MDXF They return strings with no newlines

2:55 AM

@WheatWizard Also in your Python submission s/ANSII/ANSI

@WheatWizard See my comment on your answer

@DestructibleLemon if they try to do something they shouldn't, don't just default to an action. Remove them

you want smart submissions

and you don't want to hide bugs

Destructible Lemon

ok good point there

with the bugs

what should I do with the error?

@WheatWizard Never mind about the newline. Sorry :P

Does anyone know how I could move my clipboard to a file on OSX?
