The Nineteenth Byte

@Lembik codegolf.stackexchange.com/questions/4707/…

Have you tried on small graphs to work out what general graph "shape" works the best?

11:23 AM

@somebody oh!

@Sp3000 I haven't written any code for it yet. It is all in my head :)

Well I just hope it doesn't turn out to be some super simple class :(

@Sp3000 that is a very good point

Not limit on number of vertices/edges?

no limit

except it has to run on my computer

Just thinking how the complete graph would do in my head

11:25 AM

k

I think line graphs might be interesting

but then I thought that maybe a complete graph with two lines coming out from each side might be even better

but maybe I shouldn't give away my ideas :)

Maybe you should write code :)

Or at least compare, say, a triangle vs a three-node line

yes I will as soon as I have time

but that won't be for weeks sadly

Hmm I wonder if the score increases just by having more nodes

Three-vertex line, from end: 1-cover = 4, 2-cover = 8/3. Triangle: 1-cover = 3, 2-cover = 5/3

(Approximately?)

11:44 AM

interesting!

these scores are all less than 1?

it's interesting when they go over 1 :)

Yeah, probably too small

Either that or I'm calculating incorrectly

also I think you should start in the middle

Q: Math without math class

You receive an input with a number and a string with a space in the middle. The string tells you what you need to do with the number, it can be: sqrt - squareroot pf number sqr - square of number cube - cubed version of number abs - absolute of number round - rounded version of number You n...

code-golf

because the point is that one random walk has to walk to one end and then make it all the way back

but 2 random walks don't have to do that

although I fear I am giving away all my best ideas :)

ypu? rpunded?

11:47 AM

Ah. About 5 for 1-cover and 7/3 for 2-cover?

D: new question has really bad spelling

also: You can't use a math library, even if it is built-in <- damnit, can't use jelly

@somebody that sounds good!

How does one define "math library" anyway

?

C++ is just a BIT too verbose

#define t(a,b,c)template<a>struct A b{using T=c(*)(c);};
t(int N,,typename A<N-1>::T)t(,<0>,int)

that's 98 bytes

all I need to fit in is A<99>::T() to make it a valid answer

preferably with a bigger number than 99

I mean, A<4> is already

The people voting pancakes have obviously never been exposed to quality crepes.

They don't even really have to be high quality to beat pancakes, but I still like both.

I thought a Frenchman would disapprove due to lack of accent marks in the spelling ;)

true

Is it difficult to output a ê on an american keyboard though?

no

Difficult enough that we don't :)

2:53 PM

for me it's just compose+e+'

well then I disapprove

I was just ignorant of the correct spelling :P

Wait, French or German?

Apparently from Old French Crespe

which is where the ê comes from, as in forest => forêt

I wish there was an easier way in Windows other than the alt-#### combo ... like if I could do ctrl-^-letter or something

@quintopia Up to you :) I like to use PyPy so I can test things more quickly while working on other ways of speeding them up...

I had a program that made it easy on windows once, but I don't remember what it was called.

@TimmyD on a french keyboard, you press the ^ key then e which prints a ê

Dennis

@Adnan Pulled.

2:58 PM

It works in Word similar to that -- ctrl-shift-accent then letter

There's also the Microsoft Keyboard Layout creator that exists if you're on windows

I had to create my own layout because on french keyboards there is no way to print œ,Œ, æ, Æ, É, Ç, « and » without using alt codes

which extremely dumb since a lot of those characters are used very commonly

all characters mentioned so far can be created with the compose key on Debian/others ;)

Linux distros are for nerds though

What's the deal with « and » anyways?

@PhiNotPi That's the correct way to write quotes in french

3:01 PM

@Fatalize ಠ_ಠ

And it's not on the French keyboard?

a lot of people use " instead on the computers because there are no keys for « and »

No it's not

The government recently asked the french equivalent of ISO to propose a new keyboard layout for french this year

Similarly there is no key for ’, so people just use ' for apostrophe

Wait, I thought ISO was French, since "ISO" isn't an acronym for "International Organization for Standardization" ...

International Organization for Standardization

lawl

Huh. TIL

3:07 PM

@Dennis Thanks :)

Not sure why they don't call themselves International Standardization Organization to match the acronym

@Doorknob Apparently crepe is a valid spelling in English

Makes sense. Half of us are too lazy to capitalize properly, much less do anything more than that.

Yet you decide to always capitalize I, one of the most common words. Way to go :p

I think that's more arrogance/ego than anything. If I'm talking about myself, it must be important.

at least you don't capitalize the first letter of every single noun, like in german

years of learning german have corrupted me into using extraneous capital letters

3:16 PM

German also has "I want a word for this-thing when combined with that-thing. Got it! I'll just use ThisthingThatthing"

Q: How even is a number?

The ancient Greeks had this thing called singly or doubly even numbers. An example of a singly even number is 14. It can be divided by 2 one time, and has at that point reached an uneven number (7), after which it is not divisible by 2 anymore. A doubly even number is 20. It can be divided by 2 t...

@PhiNotPi Minkolang, I choose you!

(sorry to other esolang authors, it was the first three-syllable one I thought of)

I was thinking about showing the progress of golfing a short function, in a C-like language so most people can understand it.

But it may become too cluttered.

f(i,j){i=i+(j>1)*(7-2*j)&3;return i&1?0:1-i;}
f(i,j){return(j/2&i^~i&~j>>1)*~-(j-i&2)%2;}
f(i,j){return~-(2434352710>>8*i+2*j&3);}
f(i,j){return(i/2+j+1)*(1-(i-j&2))%2;}
f(i,j){return(i/2+j+1)*-~-(i-j&2)%2;}
f(i,j){return(i<3?1-j+i/2:j-2)%2;}
f(i,j){return~-(j+2-i*i/3&3)%2;}

(from an old challenge)

what was the challenge?

Accounting for zero on the "how even" questions sucks :(

4:41 PM

0 is 0 even, right?

That's what mine does (for an extra 5 bytes, grumble).

It looked a lot nicer when it just overflowed the stack.

@AlexA. If you read this, I'd like you to test something on OS X if that is okay (and you happen to have Mono installed).

and yet when I post it alone I get 7 votes within 30m??

@orlp I closed the tab and can't find it anymore. :/

4:45 PM

0 is ∞ even. :(

But it was something like "given integers i, j between 0 and 3, return m[i][j], where m is [[0,1,0,0],[0,1,0,0],[1,0,1,0],[1,0,-1,0]]"

Semi-related: Ruby (2.3) has a neat method called dig on arrays

@ThomasKwa what about my fancy answer :(

[[0,1,0,0],[0,1,0,0],[1,0,1,0],[1,0,-1,0]].dig(1,1) == [[0,1,0,0],[0,1,0,0],[1,0,1,0],[1,0,-1,0]][1][1] == 1

even using bit twiddling :(

4:50 PM

semi-related: p-adic numbers

For the record, the OP's answer to how even looks like it loops forever on zero. It also looks to me like it doesn't work for negative numbers (unless JS has an always-positive modulus, I'm not sure).

My argument in favor is that it's 0, without the leading zero.

5:14 PM

@ThomasKwa No, 0 is a value. 00 ist the same value but with one leading (or trailing) zero. No value is no value, so "" isn't zero per se. But, it might evaluate as 0 (""*1=0 etc.) in expressions, as "" has the value 0, but 0 doesn't have the value "" in any case.

Anonymous

@VoteToClose Your job is to port Data to COBOL

@mınxomaτ I'm talking about the consistency with base 10, not any specific programming language.

@ThomasKwa "" is not a Number (not in Base 10 anyway).

@mınxomaτ Yes it is.

Try converting "" to base 10 using the base-conversion algorithm.

We start with 0, the empty sum.

There are no digits.

Therefore our result is 0.
