The Nineteenth Byte

It's really hard making a "generate a puzzle" challenge

If you look at our current set of maze generation questions, they are all terrible

Luis Mendo

@LeakyNun I'm curious, what's the role of 9**9 in your answer?

Leaky Nun

@LuisMendo it was len(input)**2 but I changed it to 9**9 seeing that 15000 is the length limit

Sp3000

@LeakyNun Too busy to golf this question so I'll leave it to you: see if 1j helps

Leaky Nun

@Sp3000 I thought complex uses floats

which is why I didn't use it

Luis Mendo

@LeakyNun I see, thanks. What's that 15000 length limit? I haven't seen it in the OP

Leaky Nun

11:09 PM

wait, the input limit is 15000, alright

> import random
max = random.randint(15,10000)
input = ''
chars = ['v','<','>','^']
for i in range(0,max): input += chars[random.randint(0,3)]
print(input)

oops, it was 10000

Sp3000

Floats are fine if the real/imag are integral, right? Or at least I mean you'd run into inputs being too large rather than precision issues

Luis Mendo

@LeakyNun But that's only an example script for generating test cases. I don't think it applies to the challenge

Leaky Nun

@LuisMendo Nope. That isn't an example script

> To generate input, you may use the following Python script:

meaning that the input is generated using that script

Luis Mendo

@LeakyNun It looks to me like it is. You hosuld ask the OP

Leaky Nun

@LuisMendo asked

Mitch Schwartz

11:12 PM

i'm going to blame not being on my usual computer for making a higher number of silly mistakes than usual

Sp3000

Don't worry Mitch, we know how awesome you are :)

Mitch Schwartz

s/awesome/silly/ thanks!

A: Sandbox for Proposed Challenges

Solve a Solitaire Chess Puzzle code-golf Recently, I was introduced to a puzzle game known as Solitaire Chess. I'll summarize the rules here: The board is a 4x4 checkerboard. All pieces are the same color (no teams) and all pieces can capture any other piece. Every move must be a capture. No ...

@LuisMendo I'm trying to golf off another byte or two, but pyth.herokuapp.com is down :/

Dennis

Use pyth.tryitonline.net.

Leaky Nun

11:15 PM

@StevenH. pyth.tryitonline.net

Luis Mendo

@StevenH. That must mean something :-P

Leaky Nun

@StevenH. Did you crash it?

Luis Mendo

@LeakyNun Huh? I thought TIO didn't have Pyth (not that I use it anyway)

Steven H.

@LeakyNun I hope not :P

Dennis

@LuisMendo It does, but it's usually quite outdated. Leaky asked me to pull it today though.

Luis Mendo

11:18 PM

@Dennis I think I only thought it didn't exist in TIO because people use the other one (heroku) more often; perhaps for the reason you pointed out

@LeakyNun complex much better :-)

Leaky Nun

@LuisMendo yep, thanks to Sp3000 assuring me that the input length would be too big before the complex becomes inaccurate floats

Dennis

Heroku also has a cheat sheet which TIO lacks. Also, it's maintained by isaacg and predates TIO.

Leaky Nun

@Dennis it's accessible in the repository

News: pyth.herokuapp.com is up again

Luis Mendo

@LeakyNun If they are double (8 bytes), the limit is 2^53. Seems plenty :-)

Leaky Nun

meaning no traffic for @Dennis

@LuisMendo sure

Luis Mendo

11:21 PM

@Leaky What does ^1 do in you code? Python ignorant here

Mitch Schwartz

xor

Leaky Nun

@LuisMendo xor

power is **

@MitchSchwartz damn, ninja'd

Luis Mendo

@LeakyNun Ah, ok. So it's like modulo 2

Leaky Nun

@LuisMendo yep

Ah, it's been days since I haven't posted any challenge

but I ran out of ideas

Luis Mendo

@LeakyNun Hm, that 1j**"<^>".find(c) has given me an idea

Leaky Nun

11:23 PM

@LuisMendo de nada

Luis Mendo

@LeakyNun :-D

Leaky Nun

> [G1Ja] % Push numerical array [-j, 1, j, -1] where j is the imaginary unit

@LuisMendo this?

Luis Mendo

@LeakyNun Yep. I may be able to use 1j raised to the index too. Let's see if it's shorter

Downgoat

@DestructibleWatermelon i like your new avatar

Leaky Nun

acuerdate darme creditos jaja @LuisMendo

Luis Mendo

11:25 PM

@LeakyNun ¡Por supuesto! Además, es una parte importante, y agradable, de esto :-)

Leaky Nun

@LuisMendo de acuerdo

Mitch Schwartz

a veces me gusta pretender que puedo hablar espanol

Leaky Nun

lol

Mitch Schwartz

pero solo es un sueno

Luis Mendo

@MitchSchwartz Pues parece muy real. Salvo la "ñ" :-P

@LeakyNun 1 byte off \o/

Steven H.

11:33 PM

@LuisMendo I'm competitive again, we're tied

Mitch Schwartz

how do you type that on your keyboard out of curiosity

Leaky Nun

@MitchSchwartz use a spanish keyboard

@LuisMendo MATL.TIO is taking an unnecessarily long time

Luis Mendo

@MitchSchwartz It's in the keyboard, left of the "L" :-)

Leaky Nun

@LuisMendo I think you meant right

Luis Mendo

@LeakyNun MATL is always slow. Is it slower than usual now?

@LeakyNun Oops very true

Mitch Schwartz

11:35 PM

ooh does it look like this fentek-ind.com/lkbsusbb.jpg

Leaky Nun

@LuisMendo matl.tryitonline.net/…

Luis Mendo

@MitchSchwartz Exactly. "ç" and all

@LeakyNun About 1 sec. That's normal

Leaky Nun

@LuisMendo alright

Luis Mendo

@LeakyNun Half of that time is Octave's symbolic package's fault :-(

quartata

Apparently my brain can't pattern match today

ASCII-only

11:39 PM

@quartata TIL quartata's brain is made of regex/haskell

quartata

Erlang in this case.

ASCII-only

or that

quartata

No need for the when if I just re-order the definitions

f([X])->X-64;f(X)->[X+64].

vs f(X)when X<27->[X+64];f([X])->X-64.

Linkroll.

Rickroll + logout.

github.com/CrazyPython/…

creditos datos

Luis Mendo

11:42 PM

@LeakyNun Haha. We interchanged the approaches

Leaky Nun

@LuisMendo interchange or exchange?

intercambiar quiere decir exchange

2

Q: "Interchange" and "exchange"

I was wondering if interchange and exchange are equivalent and can be used interchangeably or exchangeably (okay this is an example already)? What are the differences between their prefixes, inter- and ex-? It is common for XML to be used in interchanging data over the Internet.

word-choice

@LuisMendo relevant post

Rohan Jhunjhunwala

Leaky Nun habla ud. espanol?

Luis Mendo

@LeakyNun Yes, I meant "exchange". But actually I can reduce more bytes putting back modulo 11 like in your answer

@RohanJhunjhunwala Sí lo habla :-)

Leaky Nun

@RohanJhunjhunwala si

@LuisMendo vocaroo.com/i/s08Qqn4AHUkM

Rohan Jhunjhunwala

@Luis Mendo y @Leaky Nun Son uds. de Mexico o Espana o aprenden espanol con una escuela?

Leaky Nun

11:47 PM

@RohanJhunjhunwala aprendo espanol por mi mismo, @LuisMendo es de Espana

Rohan Jhunjhunwala

@Leaky Nun buenisimo!

Leaky Nun

@LuisMendo What is the difference between i and j?

Mitch Schwartz

@Neil I meant it rhetorically :(

Leaky Nun

@LuisMendo buenisimo vs optimo?

uoɥʇʎPʎzɐɹC

I created a project.

> tl;dr Basically, we combined rickroll with logging people out of their accounts. Except for the Rick Astley part.

2

bit.ly + log out of gmail and github and all that

Leaky Nun

11:51 PM

@uoɥʇʎPʎzɐɹC what would it take to make your name back to in ascii?

uoɥʇʎPʎzɐɹC

@LeakyNun huh?

Leaky Nun

Even @ConorO'Brien converted

uoɥʇʎPʎzɐɹC

Just typing "CrazyPython" or textmechanic.co's reverse generator

He changed back his name?

Leaky Nun

@uoɥʇʎPʎzɐɹC no, I mean your name here

uoɥʇʎPʎzɐɹC

@LeakyNun what do you mean?

Leaky Nun

11:53 PM

@uoɥʇʎPʎzɐɹC would you convert your name back to ascii?

uoɥʇʎPʎzɐɹC

no. never.

I have no profile pic, so this is my replacement.

Leaky Nun

why you have no profile pic

uoɥʇʎPʎzɐɹC

tells the person "oh, this person's got flair"

1. anonymity

2. dunno what to put on it

quartata

@uoɥʇʎPʎzɐɹC No actually, it just tells us that you like boxes

Rohan Jhunjhunwala

@CrazyPython I can't ping you

uoɥʇʎPʎzɐɹC

11:55 PM

@RohanJhunjhunwala start with @C

Technically, I uploaded a transparent version of my existing pic

quartata

Actually you have to start with a u

Leaky Nun

@RohanJhunjhunwala Start with u

why the fuck do I always get ninja'd?

Mitch Schwartz

why the fuck do I always get ninja'd?

oh damn

ASCII-only

@LeakyNun bad internet?

Leaky Nun

@ASCII-only slow reaction

uoɥʇʎPʎzɐɹC

11:56 PM

can someone please notice my project?

Mitch Schwartz

typos, the bane of my existence

uoɥʇʎPʎzɐɹC

github.com/CrazyPython/linkroll

1 unique visitor. nobody has clicked

rickroll + logout = ultimate troll tool

quartata

Why would anyone willing click it? It's malicious code

uoɥʇʎPʎzɐɹC

CLICK IT FOR THE CHILDREN

@quartata that link doesn't log you out

that one is instructions for how to use it

quartata

I mean the actual link.

uoɥʇʎPʎzɐɹC

11:59 PM

@quartata you wrap it in another link shortener to make it seem completely normal

Rohan Jhunjhunwala

it does not work

uoɥʇʎPʎzɐɹC

@RohanJhunjhunwala not with GitHub, yet.

but it does work with gmail, tried.
