@WheatWizard in Lost, does the IP wrap around the edges?

Wheat Wizard

@Cowsquack Yes it does

Step Hen

@HyperNeutrino wait, you don't have Fanatic?

HyperNeutrino

I lost it at 97 from getting my account deleted.

Step Hen

@HyperNeutrino o

HyperNeutrino

it was sad

totallyhuman

5:03 PM

@StepHen where'd this "o" instead of "oh" come from o0

i have never seen it being used like that before

Step Hen

> O (2): (used as an expression of surprise, pain, annoyance, longing, gladness, etc.)

totallyhuman

mm ok

wait

we had segfault in jelly CMC

CMC: segfault

Mr. Xcoder

It is

Q: Sandbox for Proposed Challenges

What is the Sandbox? This "Sandbox" is a place where Programming Puzzles & Code Golf (PPCG) users can get feedback on prospective challenges they wish to post to the main page. This is useful because writing a clear and fully specified challenge on the first try can be difficult. There is a much...

CMC (potentially main): Given two circles with different non-zero radii represented by their centers and radii, calculate the four slopes of the four lines tangent to both circles.

totallyhuman

yes but don't forget comm- to subscribe to the official doctor who youtube channel

Cows quack

CMC: convert a base-10 non-negative integer into unary

HyperNeutrino

5:14 PM

like '1'.__mul__?

Like 1ẋ? :P

Cows quack

Idk Python

@HyperNeutrino does that work for 0?

HyperNeutrino

probably

Anyone around that knows Actually

?

MD XF

Actually, no, sorry

Cows quack

5:17 PM

@HyperNeutrino just for fun, can you provide an image that shows the tangent lines for two circle as an example?

MD XF

Guys I just implemented Cubically 2, and I'm having so much fun playing around with 20x20x20 Rubik's cubes

totallyhuman

HyperNeutrino

brb making graph

Cows quack

I once attempted a similar problem to your CMC. Given two circles (with equal radii) and their velocities (along with their positions), find the exact time and point of collision

2EZ 4RTZ

codegolf.stackexchange.com/questions/64198/99-bottles-of-beer/…

My answer is too long. I had to cut my code out

Step Hen

5:22 PM

@2EZ4RTZ you only get 65536 chars

2EZ 4RTZ

@StepHen Yeah most of the code went down the drain lol

Step Hen

link to a pastebin or TIO or something

2EZ 4RTZ

i gave a tio

Step Hen

@2EZ4RTZ uh... it might have gotten truncated

I don't see it

HyperNeutrino

hi I has question how do you get formula for a line between two point

?

Cows quack

5:24 PM

first find the gradient, then insert it into y-y1=m(x-x1)

HyperNeutrino

not length

oh ok thanks

Cows quack

@HyperNeutrino will the two circles ever intersect?

2EZ 4RTZ

@StepHen edit is saving

HyperNeutrino

no

Step Hen

Is "no" really "useful / interesting for the transcript"? :P

5:27 PM

@StepHen yes

10/10 versioning

@HyperNeutrino i think you mean:

2 mins ago, by HyperNeutrino

no

Adnan

@Mr.Xcoder @EriktheOutgolfer oh yeah haha forgot about that

fyi empty program with no input is the info.txt for when you're feeling lazy

Cows quack

@HyperNeutrino btw how are you attempting to solve it?

@Cowsquack like you mean the challenge?

totallyhuman

huh?

Cows quack

the CMC

HyperNeutrino

@totallyhuman mego did not "love these"

@Cowsquack I'm not sure, I'm not going to do the math right now :P It might end up being the trivial writing of a formula into a language

Cows quack

oh lol, I thought you were already doing it

Erik the Outgolfer

5:35 PM

@Mego must've been a sacrifice huh?

ok why are we trying so hard to solve a convert-to-unary thingy when in fact you can just do b1 in jelly lol

Step Hen

@EriktheOutgolfer or lambda x:"1"*x in Python

totallyhuman

i swear i'm gonna get suspended one of these days for a pun...

Erik the Outgolfer

@StepHen does it work for 0?

totallyhuman

nope

Step Hen

@EriktheOutgolfer returns empty string, is that what you want?

2EZ 4RTZ

5:39 PM

@totallyhuman I got kicked for em

I made one pun at the wrong time

HyperNeutrino

rip

Erik the Outgolfer

@StepHen I think you're supposed to return '0' or [0] or something? or '' or []? unary is weird

Step Hen

@EriktheOutgolfer "0" would be 1 in decimal

so I think empty string is correct

Mr. Xcoder

@Mego Can you help me with something? If I have an Actually list, call it L and an index, I, how can I get L[I]? Sorry for bothering you, but I really couldn't find it in the docs.

Q: How to write zero in the unary numeral system

In decimal system: $...-3, -2, -1, 0, 1, 2, 3...$ In binary system: $...-11, -10, -1, 0, 1, 10, 11...$ In unary system: $-111, -11, -1, \text{ ??? }, 1, 11, 111...$ I only found a related question but with no answers so far: unary numbers: base-1 numeral system

notation number-systems

Erik the Outgolfer

5:40 PM

'1' would be 1 '0' would be 0 who said int(x, 1) == len(x)?

Step Hen

@EriktheOutgolfer oh, then the program is lambda x:"0"*x my bad

@StepHen wut no

still invalid?

'1'*x is correct

maybe lambda x:x*'1'or'0'

totallyhuman

5:41 PM

you can't really represent 0 in unary

2EZ 4RTZ

If that pings dennis I am sorry

Step Hen

@totallyhuman not if you use 0 for the tallies like Unary does (the language)

totallyhuman

@2EZ4RTZ >.>

Step Hen

@EriktheOutgolfer no, unary only has one symbol

2EZ 4RTZ

OH Shoot!

totallyhuman

5:42 PM

@StepHen then unary the language is not truly unary

Step Hen

unary, by definition, can't have two symbols

totallyhuman

exactly

Step Hen

0 in unary is empty string

totallyhuman

'xactly

2EZ 4RTZ

Ok so what I was doing is trying to sneak in RTL override to avoid causing a ping. Idk if it worked or not.

HyperNeutrino

5:43 PM

Another weird thing is that the maximum digit in base N is (N - 1) but if that were the case in unary then everything would be 0.

2EZ 4RTZ

That was the intended joke'

Did that ping?

HyperNeutrino

yes now stop it

Mr. Xcoder

Sure that pinged

2EZ 4RTZ

huh

It was an accident pinging dennis. next time I will not try that :P

HyperNeutrino

If you want to avoid pings, put a ZWSP between the at symbol and the name. But please stop messing around here with chat testing. We have a room for that that I'm sure you are aware of

2EZ 4RTZ

5:43 PM

It wasn't supposed to be a test :P

ZWSP?

HyperNeutrino

zero-width space

2EZ 4RTZ

oh

clever

HyperNeutrino

it breaks the ping but doesn't show

2EZ 4RTZ

huh.

HyperNeutrino

CMC: What does your username do as a Jelly program?

totallyhuman

5:44 PM

...just don't fake ping?

HyperNeutrino

Mine is mostly a huge dyadic link lol

^^

Step Hen

Wait for whom?

totallyhuman

Jelly, 12 bytes: totallyhuman

2EZ 4RTZ

I got a bug also

betseg

5:45 PM

@HyperNeutrino TypeError: object of type 'int' has no len()

Erik the Outgolfer

@HyperNeutrino wait niladic monadic or dyadic?

Mr. Xcoder

@HyperNeutrino loool, must look: Mr. Xcoder

Step Hen

@HyperNeutrino With input: TypeError: unsupported operand type(s) for +: 'int' and 'str'

HyperNeutrino

@EriktheOutgolfer like what is its function. you can assume any number of arguments if you want to make it do interesting things

@StepHen Input must be a list for you. S is sum.

Cows quack

"Cows Quack" yields 0, "Kritixi Lithos" gives a big error, ValueError: range() arg 3 must not be zero and "Kριτικσι Λίθος" gives 0 as well

totallyhuman

5:46 PM

haha my username is one of the only ones to work niladically

Mr. Xcoder

@HyperNeutrino Please test mine. ^^^^^^

Erik the Outgolfer

@HyperNeutrino well niladic is out then :/

Anonymous

@Mr.Xcoder E

Mr. Xcoder

Thanks a lot!

HyperNeutrino

@Mr.Xcoder TypeError: 'int' object is not iterable

Erik the Outgolfer

5:47 PM

you've asked that before?

Mr. Xcoder

@HyperNeutrino Try the link!

totallyhuman

oh wait my username works niladically, monadically and dyadically

HyperNeutrino

ok ok if you give me a username I can make a full explanation for you I can only do one at once though

No space

totallyhuman

dammit i got ninja'd

HyperNeutrino

k I'll to that first, short so it's a bit easier.

2EZ4RTZ should be nice; two are already nilads.

(I'm removing any spaces that aren't necessary)

Mr. Xcoder

My username does this: [1,2,3,4] -> [[0, 1], [0, 1, 2], [0, 1, 2, 3], [0, 1, 2, 3, 4]]

Erik the Outgolfer

me too

monadic

officialaimm

5:48 PM

Mine gave [0,0,0,0] :D

Mr. Xcoder

@EriktheOutgolfer Nice

2EZ 4RTZ

@HyperNeutrino I know I am nice :D

Erik the Outgolfer

and my dyadic is boring (just returns 0)

HyperNeutrino

Mr. Xcoder  Main link, argument is z
M           Indices of z that correspond to maximal elements [i for i in range(len(z)) if z[i] == max(z)]
 r          For each of the indices, get the inclusive range from that index to
  .         0.5
    X       Select a random range from one of these
     c      Combinations
      o     Logical OR
       d    Divmod
        e   Contains (right in left)
         r  Inclusive range with the input

Erik the Outgolfer

@HyperNeutrino better keep them...;)

2EZ 4RTZ

5:50 PM

Who pinged me???

I got got 2 ping sounds

HyperNeutrino

The explanation near the end doesn't make much sense but I'm not sure it's a valid program.

totallyhuman

@HyperNeutrino wait did you automate this?

2EZ 4RTZ

TNB is giving ping sound for every message?

HyperNeutrino

@totallyhuman of course not

totallyhuman

@2EZ4RTZ click on the speaker button to the top right

HyperNeutrino

5:51 PM

I should do that sometime :3

Mr. Xcoder

@HyperNeutrino Very nice, very nice!

AdmBorkBork

@Mr.Xcoder lol, mine is boring

2EZ 4RTZ

@totallyhuman I thought it would just tell me when I was pinged in any room at all

Anonymous

@2EZ4RTZ Check your sound notifications. It sounds like you have it on "visible room" or "all my rooms"

Erik the Outgolfer

it should be "when mentioned" not "visible room" or "all my rooms"

2EZ 4RTZ

5:51 PM

Yeah I fixed it.

Anonymous

Change it to "when mentioned" to only get sounds on pings

HyperNeutrino

2EZ 4RTZ  Main link
2         2
 E        All equal? (1)
  Z       Zip (error)

totallyhuman

you get the ticker thingy at the top for a ping in another room

if you're not in there

@HyperNeutrino along with the fancy search bar

HyperNeutrino

oh yeah about that xD

@2EZ4RTZ see above

2EZ 4RTZ

@HyperNeutrino rip

totallyhuman

5:53 PM

wait you could probably do something like this on heroku

i really need to learn django or something

HyperNeutrino

idk what that is, but if I could do it in JavaScript then I could just make a webpage and do it client-side and load the scripts over to the client ¯\_(ツ)_/¯

totallyhuman

yeah or you could do JS

but JS is... JS

HyperNeutrino

@EriktheOutgolfer How does a line of a bunch of dyads (like totallyhuman) chain together in Jelly?

(as you can see I have not completed Jelly training :3)

totallyhuman

haha my username confuses you

lel

HyperNeutrino

too many dyads >.<

Erik the Outgolfer

5:55 PM

@HyperNeutrino well it isn't supposed to :p

@HyperNeutrino btw it's supposed to be broken to tot a l l y h u m a n or something like that...

HyperNeutrino

5:56 PM

oh ok

Erik the Outgolfer

first of all tot doesn't make any sense at all!

HyperNeutrino

how many arguments does that consume

@EriktheOutgolfer yeah lol
