Refer to an above conversation

They added rubber duck debugging

And can you find a way to make this grammar non-left-recursive?

from modgrammar import *
from functools import *
from math import *

#grammar_whitespace_mode = 'optional'

class Name(Grammar):
	grammar = ONE_OR_MORE(OR(WORD('a-z'),WORD('A-Z')))

class Term(Grammar):
	#grammar = OR(Name, (REF('Term'),'.',Name), (REF('Term'), '(', REF('Term'), ')'))
	grammar = OR(Name,
		(
			REF('Term'),
			OR(
				(L('.'), Name),
				(L('('),REF('Term'),')')
			)
		)
	)

	def grammar_elem_init(self, sd):
		if isinstance(self[0],Name):
			self.value = [self[0].string]
		elif self[0][1].string == '.':

I was confused when I saw the duck.

I didn't realize that it hadn't been added before April Fools, because I haven't used the site too recently.

I thought it was a couple of days before.

I was pretty impressed; I thought it was for offering help with navigating the SE system.

Q: What the duck ...?

There is a duck in the bottom right corner. It is asking me whether it can help, absent any indication that I am indeed in need of help. There is no "no thanks, go away" option. The duck asks whether I have a microphone. I click "no" and it starts listening. It asks me to speak up louder. F...

Zacharý

@orlp wut language?

that it's not symbolic differentiation

and it's also not numerical differentiation

@Zacharý eh.. math?

Zacharý

Automatic differentiation? WTF is that? e^x => e^x ?

@Zacharý it's a system which you can use to efficiently calculate derivatives of arbitrary closed forms

Zacharý

4:18 AM

Cool

orlp

Automatic differentiation

In mathematics and computer algebra, automatic differentiation (AD), also called algorithmic differentiation or computational differentiation, is a set of techniques to numerically evaluate the derivative of a function specified by a computer program. AD exploits the fact that every computer program, no matter how complicated, executes a sequence of elementary arithmetic operations (addition, subtraction, multiplication, division, etc.) and elementary functions (exp, log, sin, cos, etc.). By applying the chain rule repeatedly to these operations, derivatives of arbitrary order can be comput...

Seems familiar: I made a JS program that abused the chain rule to no end, along with abusing objects, to calculate the derivative.

user202729

@orlp Doesn't look much different from symbolic differentiation.

I remember making something like that too, an object that has a lot of overloading.

orlp

4:24 AM

@user202729 it's very, very different

Zacharý

@DJMcMayhem I've reversed the edit you approved on this challenge there was discussion as to whether the tag fit earlier and it was decided it did not. Obviously you can readd the edit but you might want to look more carefully at the tag and question.

This one is also borderline but I have left the edit.

DJMcMayhem

@user56656 Whoops, my bad.

There were so many of them, I was skeptical at first but then I started rapid-fire approving them

The most recent one is also a bit borderline

user56656

Which most recent?

My most recent or your most recent

DJMcMayhem

codegolf.stackexchange.com/review/suggested-edits/47300

It's definitely related to fibonnacci, but it seems like a minor add on out of a bunch of unrelated things

user56656

I approved it. It's not the focus but the challenge does involve calculating the fibonacci sequence.

DJMcMayhem

Once I hit Steward (in 2 more reviews), I'll probably ease off my aggressive reviewing to let other people get a chance to review things

@Cowsquack perl 5?

@Neil no, some compression bugs. but good catch. i should fix that as soon as i can

@Zacharý kinda. i was in the cs club at my uni, where an ex-PPCGer was on the council thing

@Downgoat re: comments, looks like is problem only on empty comment. re: units, do it whatever way we'll do 10.str() or whatever. unless you mean how to represent units in which case make them a struct-ish thing, because exponents, things like cm^2, and multiple units.

9:11 AM

@Zacharý ~~kinda~~ not really but i posted an answer in ><> because of my avatar once

Cows quack

@ASCII-only no, JS

ASCII-only

@Cowsquack yeah that's one problem

@Cowsquack a lot of things are super verbose in perl...

Cows quack

problem?

also is print the shortest way to print? (do you know what JS engine is used?)

ASCII-only

9:28 AM

@Cowsquack yes. Mozilla (see about page >_>)

@Cowsquack problem is it's not the same language. as you can see perl 6 is shorter for most challenges

@Cowsquack problem is i'm only using perl 5 atm. as you can see perl 6 is shorter for most challenges

Cows quack

I was saying my JS solution was 2 bytes longer than your JS one

ASCII-only

@Cowsquack hang on brb

@Cowsquack :| regex is too long to be feasible in JS anyway?

Cows quack

yeah

Cows quack

9:43 AM

nice work ASCII-only

ASCII-only

@Cowsquack ?

Cows quack

you got 54 53 bytes

ASCII-only

:| nowhere close to 39 though

i should probably wait a while before trying the regex solution shouldn't i? didn't realize two loops are probably so much more ungolfy than a regex

Cows quack

I'm using one loop, but also use arrays (wow they're ungolfy)

ASCII-only

10:02 AM

@Cowsquack :|. also considering that the current best (well, the one that i assume doesn't use regex) is 45 bytes, we still have a lot to improve

also O_o same bytecount already

@Cowsquack also yeah arrays are the worst

Cows quack

hmm I get 60 with regex

ASCII-only

i have a nice one but it's 55 bytes :(

Cows quack

do you store the counter as a string?

ASCII-only

@Cowsquack 1. 55 byte one is not using regex 2. i haven't used string counter in any of my solutions yet.

@ASCII-only *single-loop, array solution

Cows quack

10:23 AM

that's similar to my 57 one

ASCII-only

*static array

found a 57-byte normal array solution

Cows quack

static = doesn't change?

is this your normal array solution for(i=2,a=[];i<98;a.push(i++))if(a.every(q=>i%q))print(i) ?

ASCII-only

yeah

@Cowsquack close enough

i only added primes because i was stupid, but yeah

@Cowsquack 55: for(i=2,a=[];i<99;a.push(i++))a.every(j=>i%j)&&print(i)

Cows quack

ah, nice

ASCII-only

note: i rewrote it but it happened to be basically the same >_>

side note: you should try getting it down to 50 :P

Cows quack

10:37 AM

thanks, you've given me inspiration to get 52

ASCII-only

@Cowsquack wait do you not use short circuits :|

Cows quack

>_>

ASCII-only

aren't short-circuiting operators like golfing 101

at least i've been using them basically whenever possible

Cows quack

is there a similar challenge on ppcg?

ASCII-only

don't think so

PPCG doesn't really do listing-type challenges anymore

also :|||||||||||| two loops look really ungolfy but i don't see any way i can merge them

H.PWiz

10:51 AM

@user202729 As usual, it's a lot nicer in Haskell

ASCII-only

@H.PWiz protip: multiline message has no length limit

H.PWiz

Oh, thanks!

Cows quack

I'm repeating a variable initialisation twice, I'm trying to see if I can do without one

ASCII-only

@Cowsquack protip: second statement in for loop executes before loop body. although you probably already knew that.

@H.PWiz also no formatting but that's a small price to pay imo

user202729

@ASCII-only ... Really? I think the limit is just much larger. Let me try...

ASCII-only

10:56 AM

@user202729 try in sandbox pls

user202729

@ASCII-only of course

Cows quack

@ASCII-only I have j=0 in both the inside and outside loops

ASCII-only

@Cowsquack :| why do you even need j in outside loop

Cows quack

~~for printing it~~ nvm

I need j in the outside loop

for printing i

user202729

Browser crashed...

10:59 AM

@Cowsquack if you don't use it until after it's initialized then it's ok

@user202729 10/10

@Cowsquack wait O_o 47 what black magic did you use

user202729

(come on, it's just 199999 characters)

(not really crash, but it's currently using 100% of one of my CPU)

Cows quack

that's why I have j in the outside loop :)

@ASCII-only what do you have?

user202729

... it's not exactly 199999 chars, just Jelly being unintuitive.

> The message is too long.

See? It's not infinite.

ASCII-only

@Cowsquack ?

user202729

Now binary search for the bound...

ASCII-only

11:03 AM

@user202729 well it's basically infinite :P (for sane people)

user202729

(or just reading the Javascript code would help? Is the validation done client side or server side?)

ASCII-only

@user202729 i'd assume both

Cows quack

@ASCII-only what is your code?

user202729

ASCII-only

@user202729 i'm sure that's not the limit for multiline messages...

What should I do if I flagged a post and it was disputed but I am sure that the flag was valid?

Q: Asterisks viral

Given the number of asterisks N ("virality") your program should duplicate the asterisk N times in the each of right and bottom branches. The direction of each branch after the first asterisk can be either "to the right" or "to the bottom", which is determined randomly*. The base of any output...

Do not flag the 'Room automatically frozen for inactivity' posts from the system as rude/offensive with mod flags. It makes noise, and causes us all grief.

user56656

It just doesn't do the task.

DJMcMayhem

@user56656 I'll look into it

Thanks!

DJMcMayhem

Fwiw, you can ask about declined flags on meta. I see that on SO pretty frequently

user56656

Ok. I'll do that if there is a next time.

@user56656 I also have no clue how disputed flags work lol

Can anyone tell me if they find problems/or have any comments/questions regarding VSL AMM spec: hackmd.io/s/HyDjTh0cz

Zacharý

Quick question: would a knight that could move anywhere in radius sqrt(13) be overpowered?

orlp

8:40 PM

@Zacharý ANYWHERE?

within that radius?

Zacharý

Yes.

orlp

eh of course it would be

it'd be the best piece by far

it's better than a knight

it's strictly better than a rook

because it can also capture/check behind pieces

Zacharý

Would restricting movements to the corners defined by its original movements be overpowered?

orlp

actually wait

sqrt(13), not 13

so not Strictly better than a rook

Zacharý

I meant anywhere that is ON radius sqrt(13)

orlp

8:44 PM

that's what I asked

within or ON

Zacharý

I misread it.

Sorry >_<

orlp

what is a move that is on that?

Zacharý

I'm starting again at coding my [[0,8)^2 chess game (no engine, obviously)

orlp

wait not integer chess?

you have to be a bit more elaborate

Zacharý

No, not integer chess.

Some reasonable subset of R

[-1/2, 15/2]^2.

That's good.

orlp

8:47 PM

I have no idea how that'd even work

like captures

Zacharý

I have it planned out, no idea how to start programming some of it though (like CHECK and CHECKMATE >_<)

No piece sit within an open circle of radius 1 of another piece. That defines what would be capturable. And for every piece but a knight, a piece would be blocked from moving to a square if it has a piece in a place that it will not capture in a radius one circle of any of the points on the segment that connect the origin point and the destination point.

I like some of the rules I came up with

King: max(|dx|,|dy|)=1

I might have just confused you more.

@DJMcMayhem I've done that once here

the answer revealed a major flaw of our community

@Zacharý you should ask the duck

he solves all problems tbh

Erik the Outgolfer

eh, I can't seem to be able to find any converter that can convert the duck's answers to a more, well, human-friendly format online
