Yay I've done 1000 reviews!

Now to do 1000 in a single category

ETHproductions

Why does the main review center link to the meta one, but not vice-versa?

undergroundmonorail

Hey, can someone help me make a decision real quick? I posted a challenge that includes this table:

Someone's asked if they can take the number on the right as input rather than the string on the left, and my original intention was "no" but I'm not sure that requiring they take a string makes the challenge any more interesting

I was hoping people would find patterns in the strings or something but maybe all that will happen in practice is people have to hardcode the whole table

ETHproductions

What does the output need to be?

The result of a roll of one of those dice?

undergroundmonorail

No, it's a whole computation, but the only way the input of a class matters is to determine which of those dice to use

Here I'll just link the thing

uh, not what i thought i had copied

Q: D&D 5e HP Calculator

For this challenge, you will write a program or function to calculate the correct value auto...

code-golf

although, it actually has acquired some answers since I started thinking about it, and they are doing interesting things with the string requirement

so i guess my fear of "it just means hardcoding the whole table" is null and void and i can enforce the string requirement

Laikoni

Yes, after some answers have come in it's usually not well received to change the spec.

undergroundmonorail

4:25 PM

yeah

although in this case it would be a trivial change that would save bytes so it wouldn't be too bad, but still

ETHproductions

I was thinking it just seems like something tacked-on to the main part of the challenge, but looking at the JS answer I'm thinking it may be just fine

undergroundmonorail

It's been sitting in the sandbox for 12 days and then when I post it I get asked for clarification half an hour later :P

Not even, like 20 minutes

Which like, I get, waaaaay more eyes on the main site

It's just funny to me

CMC: reverse run-length encoding. e.g. [1,2,3,4] -> [2,2,4,4,4,4] (you can assume that the array contains only positive integers and has even length)

Kritixi Lithos

How does that work?

ETHproductions

I assume we can take input as [[1,2],[3,4]] as well?

Business Cat

4:33 PM

Any restriction on the format, as long as it's reasonable?

Leaky Nun

@ETHproductions I don't think so

@KritixiLithos [1,2,3,4] = 1 instance of 2, 3 instances of 4

Kritixi Lithos

But in the output, there are two 2s instead of just 1

Leaky Nun

oh heh, what on earth was i thinking

e.g. [1,2,3,4] -> [2,4,4,4]

ETHproductions

Japt, 11 bytes: ä@XÇY}Ãë2 c

Fortunately, flattening an array is much easier in Japt than condensing one into multiple arrays... :P

Basic algorithm: take every consecutive pair of items in the input, map each pair X,Y to Array(X).fill(Y), take every other array, flatten

Leaky Nun

@ETHproductions what does safe mode do?

ETHproductions

4:39 PM

It just doesn't allow you to execute arbitrary JS (with Ox"...")

Leaky Nun

Is that a security safe mode?

if it is, I suggest you hard-wire it on

ETHproductions

It really just means you can't do random things like mess with the page, send AJAX requests, or whatever other crazy things one might try to do

It's for the user's safety, not mine. I don't have a server or something that one could potentially take out

Anything you could do with Ox, you could do in your browser console. I think I added safe mode back when a group of users was putting together DataBot or whatever that was, but it turned out unnecessary anyway

Damn, braingolf fails the one true test of a language: It can't do Fizzbuzz :(

mbomb007

Why not?

Mayube

It can't do nested if statements. There's no feasible way to check whether you've printed "Fizz" or "Buzz" already for the current number, and print the number if you haven't

mbomb007

@flawr I think there's an anime where a guy eats his food with a pistol... I'm trying to think of what I was watching...

Mayube

closest I can get is it prints a newline every number, and prints "Fizz" if n % 3 == 0 and "Buzz" if n % 5 == 0, but according to most FizzBuzz specs if neither are true you should output the number, mine just outputs an empty line

@mbomb007 I know exactly which anime you're referring to but I can't for the life of me remember it's name. Dude eating noodles with a gun

mbomb007

@PhiNotPi What happened when you clicked it?

DJMcMayhem

@Poke If you use the same instance of vim for very long, eventually your buffer list will get all cluttered with a bunch of files you don't really want anymore. It's really convenient to switch between buffers with something like :ls<cr>:b <n>, but if you have to look through 2-dozen buffers, it's hard to find the one you want. This will close all the ones your done with

PhiNotPi

So I guess I did what I could... revoked app permissions and sent a warning email to all the people the app sent an email to.

Anonymous

if(x % 3 == 0){printf("Fizz");} if(x % 5 == 0){printf("Buzz");} if(x % 3 != 0 && x % 5 != 0){printf("%d",x);} printf("\n");

@Mayube Can you push an arbitrary number of elements to the stack, do modulo and multiplication, and rearrange/duplicate stack elements?

Mayube

@Mego eh depends what you mean by arbitrary number, you can push as many as you want to the stack within python's list bounds :P As for everything else: yes, it can

Anonymous

Then you absolutely can do fizzbuzz

Mayube

Well, it can only rearrange stack elements in the sense that it can shift the whole stack uniformly.

Like you can't take the 3rd element in the stack and move it to the end, not without moving the whole stack relatively
