@JohnDvorak hi.. are you about?

Spreadsheet Columns code-golfsequencealphabet In most spreadsheet programs, columns go A, B, C, ... X, Y, Z. After this comes AA, AB, AC ... AX, AY, AZ, BA and so on. Your task is to convert one of these letters in to a columns number. Test Cases: A => 1 B => 2 Z => 26 AA => 27 AC => 29 AZ =

@JohnDvorak hmm.. my attempt to code that up in python is:

n = 6

def a(n, k):
    if k < 0:
        return 0
    if n == 1 and k == 0:
        return 1
    if n == 1 and k != 0:
        return 0
    else:
        return a(n-1, k) + a(n, k-1) - a(n, k-n)


for k in range(n):
    print(a(n,k))

(the indentation seem to have disappeared annoyingly)

@Anush Indentation only happens in chat if you click "fixed font"

@cairdcoinheringaahing where can I click that?

aha

@cairdcoinheringaahing I don't get what I am doing wrong. I am trying to copy the Ruby code from:

bpaste.net/show/xe0W

but I seem to have failed to do that.. as in my Python code doesn't seem to give the same output

any ideas why?

@Anush You may want to ask someone who knows what it does :P I can only help with the chat indentation

H.PWiz

It looks like you wrote a(n, k-n) instead of a(n-1, k-n)

ah yes!

that's because I copied math.stackexchange.com/a/3371298/72724

always trust ppcg over mathematicians :)

how can the python code be made iterative? It fails with a complaint about max recursive depth if you increase n much

1:58 PM

can anyone help with my confusion ? bpaste.net/show/Oivw

can someone explain to me why this website seems to be imploding

thank

@aspaghetto Imploding?

Also, I'm remembering why I hate HTML/CSS so much :/

For TIO links where you are using the "Input" section to provide input by stdin, is there a way to run multiple examples? Eg in this awk answer I'd like to provide more test cases...

DJMcMayhem

@aspaghetto Code golf specifically, or SE in general?

all of the above except for whatever MSO is complaining about because they do not ex;st

although i am only here because of that PPCG meta post showing up in my TL

A: Create a programming language that only appears to be unusable

@Jonah You could use some bash trickery as all the interpreters are available through TIO, but I don't think there's any other way

Conor O'Brien

Rainbow (Note: Interpreter coming soon) I know this challenge expired. Rainbow is a mix of... a lot of things. Rainbow is a 2D stack-based language with two stack (Like Brain-Flak) and 8 directions (N NE E SE S SW W NW). There are 8 commands: 1, +, *, " do exactly what they do in 1+. ! toggl...

Thanks @cairdcoinheringaahing

@NewMetaPosts maybe we could move ppcg to an own site, independent of SE?

Unrelated String

There was this, maybe we could revive it

We have a discord server, apparently; discordapp.com/channels/133419285409169408/133419285409169408

DJMcMayhem

It's pretty dead

flawr

@UnrelatedString I vaguely remembered this!

9:08 PM

@aspaghetto oh hey you're back

long story short a mod on mi yodeya (Monica) was removed without any real notice why due to conversations where she disagreed with a policy that had yet to be implemented

I believe many moderators are stepping down not necessarily out of support for monica's disagreement (which was touchy in and of itself) but mostly out of the fact that SE corporate decided to stop debating and just nuke her modship

@Riker I think this is the best summary so far, thank you

Q: Find the leading root of a polynomial with a neural network

probably safe to say -most people are mad at SE's response, but some are also mad at each other, so it's all falling apart

The challenge Find the smallest feedforward neural network such that, given any 4-dimensional input vector \$(a,b,c,d)\$ with integer entries in \$[-10,10]\$, the network outputs the largest (i.e., "most positive") root of the polynomial \$ax^3+bx^2+cx+d\$ with error strictly smaller than \$0.1\...

@Riker not just mi yodeya, also like 5 other sites

@Doorknob did not know this, thank you

none as part of this current 'discussion' though, right? (removed, not resigned)

El'endia Starman

Monica was a mod on six sites. She had all her diamonds removed at once.

ah my bad I knew that, I thought doorknob meant 5 other sites not just mi yodeya lost mods

El'endia Starman

It's more than five now but yeah, those ones resigned.

ngn

is there any public info about what policy the mods and cm-s were debating before monica got kicked out?

9:38 PM

@ngn Not yet, as far as I can tell.

El'endia Starman

Not yet. Should be posted by SE this week. ... Hopefully this week.

The full story will probably never become public, but I think I'm probably allowed to say that nobody was acting out of malice.

Good to hear that there was no malice

@wizzwizz4 The discussion is quite lively in TMR. Would you like to join in?

@JohnDvorak Not really; I've had enough of this, and I'd have to be withholding information the whole time. It's just… sad, really, that it's got to this point.

I think you'll probably be able to figure out most of what happened when the next significant, network-wide announcement comes out, and then you'll probably agree that it's really sad. And frustrating. I will say no more.

Thanks.

Should I share your message in TMR then?

9:50 PM

If you like.

Do you happen to know when we can expect the announcement?
