The Nineteenth Byte

Nathan Merrill

06:00

I guess it depends on your interpreter

Doorknob

@DmitryKudriavtsev Now you're disallowing flags like -p for Perl

Dr Green Eggs and Iron Man

And a comma (I think)

Mᴀʀs Uʟᴛᴏʀ

@DmitryKudriavtsev but would say python -c "print 'Hello, world!'" > o in a bash file be allowed?

Dmitry Kudriavtsev

No.

Please read the last line of the question/challenge.

I'll even quote it for you guys:

Doorknob

Anyway, I understand the intent of your rule now. (undownvoted your Bash answer)

Dmitry Kudriavtsev

06:01

> Follow the spirit, not the letter, of the rules.

Dr Green Eggs and Iron Man

@MᴀʀsUʟᴛᴏʀ if it's a bash file, why not just echo?

Dmitry Kudriavtsev

@Doorknob Thank you.

Nathan Merrill

@DmitryKudriavtsev "Spirit of the question" is simply not enforcable

Doorknob

@DmitryKudriavtsev That doesn't mean anything. Who gets to decide what that means?

Dr Green Eggs and Iron Man

^ & ^^

Dmitry Kudriavtsev

06:01

@Doorknob I do

Doorknob

That's not how objective specifications work

Dmitry Kudriavtsev

Please reread the rules, i edited them.

also, my Bash script still has -2 votes. Should I just delete and repost it?

Doorknob

No

Dmitry Kudriavtsev

?

Nathan Merrill

that doesn't recover rep anyways

Dmitry Kudriavtsev

06:03

Not the point

The point is visibility of my answer.

Dr Green Eggs and Iron Man

@NathanMerrill yeah it does?

Dmitry Kudriavtsev

If it's on the bottom and has low score it'll just keep being downvoted.

Nathan Merrill

@DrGreenEggsandIronMan what? how is that not abusable?

Dmitry Kudriavtsev

I'm trying to get it to show up.

Doorknob

@NathanMerrill autoflags when users self-delete excessively, etc.

Nathan Merrill

06:04

huh. TIL

Dr Green Eggs and Iron Man

@NathanMerrill that's the opposite of abuse. If an answer is bad enough to lose the author rep, it encourages good behavior for them to delete the incorrect answer (for a Q&A site)

Nathan Merrill

huh, I never thought of it that way

good point

R. Kap

You know, it seems like my challenge is very trivial. Although it may be too late to make any drastic changes now, do you think I could have disallowed the use of the explicit formula to solve the challenge?

Nathan Merrill

@R.Kap what do you mean by "formula"?

R. Kap

@NathanMerrill The formula m*n*(m+1)*(n+1)/4

That is the explicit formula defined for the number of rectangles.

Nathan Merrill

06:07

right, but is m*n*(m-1+2)*(n+1)/4 the formula?

Sherlock9

m*(m-1)/2 * n*(n-1)/2 where m and n are the number of grid lines horizontally and vertically, respectively

Dmitry Kudriavtsev

NO ONE has even VOTED on my question

Sherlock9

Because we're still debating it here

Zwei

if you ban that formula, I'll just use the triangle number one :^)

Nathan Merrill

@R.Kap my point, is that its really hard to make restrictions/exceptions. That's why Do X without Y challenges are usually off topic

Mᴀʀs Uʟᴛᴏʀ

06:08

@R.Kap That's just the triangular number formula multiplied together, and that's assuming some points are collinear, otherwise m == n

Doorknob

@DmitryKudriavtsev Don't delete and repost posts. It creates unnecessary clutter.

R. Kap

I now feel like answers to my challenge are only going to differ in the language used.

I spent hours on that challenge...

Nathan Merrill

@R.Kap if you are going for non-triviality, create a part 2, where rectangles have to be unique in size (and you list the coordinates for the lines)

R. Kap

@NathanMerrill I wanted to use coordinates in this challenge, too, but @HelkaHomba said it would be better to use a 2 integer input.

Dennis

@orlp Jelly's base conversion supports array -> integer with a complex base, but I'm not sure how it would help here.

Dr Green Eggs and Iron Man

06:11

@DmitryKudriavtsev No one is obligated to. I didn't upvote it because it's not an extremely interesting challenge. Since there's no algorithm or logic to implement, the shortest answer purely comes down to language syntax.

Sherlock9

@R.Kap What's done is done. Make another challenge and I promise to help if I can

Nathan Merrill

@R.Kap the coordinates for points was a bad idea IMO. However, listing coordinates for lines is a much better one.

Dr Green Eggs and Iron Man

Don't take it too personally. Writing good challenges is extremely hard.

Nathan Merrill

^

orlp

@Dennis oh no it doesn't I'm kinda dumb today sorry

Dr Green Eggs and Iron Man

06:12

Try the sandbox next time, it'll help.

R. Kap

@NathanMerrill I'm thinking of creating one where not only horizontal and vertical lines are used, but also diagonal lines, so you have to count all the polygons created.

Nathan Merrill

(that's literally the first time I've careted)

DerpfacePython

@LeakyNun Uhhh... I'm going to upload the Pyramid solution tonight.

Sherlock9

@R.Kap Ooh :D

DerpfacePython

For the 16 logic gate thing.

Nathan Merrill

06:13

@R.Kap maybe? I still like the original one

R. Kap

@NathanMerrill I still feel like that could be trivial somehow.

Nathan Merrill

@R.Kap oh, if you do do that, are you counting concave polygons?

Zwei

@DrGreenEggsandIronMan by the way, how would I do escape in V?

Helka Homba

@R.Kap Yeah but I'm not always right. I didn't realize it would be just T(n)*T(m)

:shruggyguy:

Zwei

or anything like <C-a>

Dr Green Eggs and Iron Man

06:15

@Zwei Do you have vim installed? That helps.

Nathan Merrill

@R.Kap a really good test is to create a sequence based on your problem, and then enter it in at OEIS

Zwei

I use neovim but am on my iPad right now

Dr Green Eggs and Iron Man

Unfortunately, it requires the actual unprintable ASCII character

Zwei

ahh

Dr Green Eggs and Iron Man

I'm working on a way to make that more convenient

R. Kap

06:15

@NathanMerrill Both convex and concave. What do you think?

Zwei

how about ^a for <C-a>

Dr Green Eggs and Iron Man

Although I'll be pretty busy these next couple weeks so it won't happen any time soon

Zwei

okay

R. Kap

@DrGreenEggsandIronMan Are you talking to me? If so, I did use the sandbox.

Nathan Merrill

@R.Kap I'm actually guessing that allowing concave has a higher chance of being trivial

but I may be wrong

Dr Green Eggs and Iron Man

06:16

@Zwei That's not ideal since ^ is also a vim command, and ^a is two bytes, not one.

Zwei

right

Dr Green Eggs and Iron Man

@R.Kap no, I was talking to Dmitry

R. Kap

@NathanMerrill Both will be even more nontrivial. And I doubt there will be any sort of sequence when using diagonal lines.

@DrGreenEggsandIronMan Oh, ok.

Nathan Merrill

@R.Kap probably. If you allow concave, then people may take the lines, convert it into a graph, and then count the number of circuits in the graph

Dr Green Eggs and Iron Man

@Zwei what I'm going to do is pick some unicode characters, and internally map them to the unprintable ones. I've picked out a few, but most of them I'm still undecided on. I know I want alpha == ^a, and ♡ == ^v

Nathan Merrill

06:19

convex-only will actually require measuring angles

(that said, I'm not sold on which on is better)

Dr Green Eggs and Iron Man

And also, bytes above 0x80 are all mapped

Nathan Merrill

I kind of like the idea of turning an image into a graph

Zwei

ahk

I'm just trying to figure out how to get unprintable ascii characters in the tryitonline thing

Helka Homba

is lexicographically = lexically? (as in alphabetical ordering)

Dr Green Eggs and Iron Man

I actually use vim on mobile. It's the most convenient way I know of.

Zwei

06:22

I do believe that lexicographic ordering is indeed alphabetical ordering

Dr Green Eggs and Iron Man

Does that make me a nerd if I have vim and python both installed on my phone?

DerpfacePython

What does implies mean?

So like a implies b.

Hello?

Zwei

how did you get vim on your phone?

the best I can think of is sshing into a raspberry pi

Dr Green Eggs and Iron Man

No, it's all native

Zwei

oh

well, won't be able to do that on my iPad

Nathan Merrill

06:24

@DerpfacePython it means that if a is true, then b must be true

Dr Green Eggs and Iron Man

It's on the app-store, although I'm on a Droid. Not sure if it's on iPad.

Doorknob

@Zwei termux.com or similar

Zwei

I wanted some android device but no, I had to inherit an apple thingy :(

DerpfacePython

@NathanMerrill So if a = 1, then b must = 1?

R. Kap

@NathanMerrill But is that really is easy as it sounds? If so, then I will allow only convex.

Nathan Merrill

06:25

@DerpfacePython only if you mean 1 for boolean values

Dr Green Eggs and Iron Man

@Doorknob "Your device is not compatible with this version" ;_; Y U do dis Google?

Nathan Merrill

@R.Kap neither of them are easy. Converting a bunch of lines into a graph isn't trivial (but isn't too difficult either*

finding all of the circuits in a graph, however, is pretty trivial

R. Kap

@NathanMerrill Well, you don't want it to be too easy, but you also don't want it to be too difficult, correct?

Nathan Merrill

@R.Kap depends on what you want. My highest upvoted questions are my least interesting

R. Kap

@NathanMerrill Well then, in that case, I will only make it too that they have to count the convex polygons, although can;t that circuit method also be applied to those?

Dr Green Eggs and Iron Man

06:28

Dang it. I wanted to be the first to congratulate Martin on 100k, but it'll probably happen while I'm asleep. :/

Doorknob

We beat CR

Nathan Merrill

@R.Kap no, a more complex data structure would be required. A graph doesn't know anything about angles

Dr Green Eggs and Iron Man

Well, technically not yet. :P

Dennis might suspend him to take the lead, haha.

R. Kap

@NathanMerrill All right then. I'll propose that challenge right now, although then I will have to make another GIF...

Dr Green Eggs and Iron Man

I seriously need some shut-eye. G'night everyone!

R. Kap

06:31

@DrGreenEggsandIronMan G'night mate.

I have a challenge type idea that I'm not sure will work

step-count where the challenge is to create a program that will solve the challenge using as few steps as possible. Steps defined as assignments, each step in a map, for loop, while, other distinct statements.

I'm not sure what will count at the moment

Thoughts?

Mᴀʀs Uʟᴛᴏʀ

@Sherlock9 That would be like fastest-code

plus, lower-level code will almost always perform less well, although i guess that's what normally happens

Sherlock9

07:56

I'm just thinking in terms of steps on a really long flowchart.

Dennis

@LeakyNun There seems to be a bug somewhere. I should be able to remove the last jnz from this answer, but it enters an infinite loop after printing the first line. Will investigate tomorrow.

zyabin101

Hello

Dennis

This is also an infinite loop. Weird.

Nathan Merrill

08:09

@Sherlock9 nested loops would get really hard to count. Do if statements count? how many steps is Integer.parseInt("34"+"4726").byteValue()?

also, what about exceptions?

zyabin101

I have lost my new Stack Overflow Extras (SOX). ;_;

Mᴀʀs Uʟᴛᴏʀ

@zyabin101 No, just he missed a day

what does that even have to do with having the 'remember me' option checked

Sherlock9

08:12

@NathanMerrill Checking an if counts as how many steps in the condition + check the condition. Not sure how "parseInt" works there

Things like "byteValue()" and "print()" will probably be counted as one step

Dennis

@Dennis @LeakyNun Fixed.

@R.Kap UTF could mean UTF-8, which means two bytes are used for the macron.

R. Kap

@zyabin101 But then why does ord count it as 1 byte?
