Are you converting the result back into the base 64?

well what are you doing with the =

And not the right town either :p

caird coinheringaahing

Are you telling me you don't use a hotmail email? :P

Redwolf Programs

And my first name is not actually leo :p

hyper-neutrino

well i have

console.log((x=>((x,y)=>atob(x.map((e,i)=>g.charAt(e^y[i%y.length])).join("").replaceAll(" ", "/").replaceAll("-", "+")))(...x.map(x=>[...btoa(x).replaceAll("+", "-").replaceAll("/", " ")].filter(x=>x!="=").map(x=>(g="ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789- ").indexOf(x)))))(["This is some plaintext", "the-key"]));

and it's giving me random garbage

this is 10x more javascript than i'm willing to write on a good day

Hint: The input is in base64

Unless you're already doing that

I can't tell

hyper-neutrino

oh

yeah i'm going back to using python

caird coinheringaahing

What do atob and btoa mean again?

Redwolf Programs

Nobody can remember

Legend has it btoa is text to base64

But nobody has survived to tell

A: Why were Javascript `atob()` and `btoa()` named like that?

The atob() and btoa() methods allow authors to transform content to and from the base64 encoding. In these APIs, for mnemonic purposes, the "b" can be considered to stand for "binary", and the "a" for "ASCII". In practice, though, for primarily historical reasons, both the input and outpu...

Redwolf Programs

Ironically atob and btoa are entirely useless for actual binary data

The whole entire point of base 64

hyper-neutrino

8:08 PM

python base64 requires byte I/O which is actually kind of annoying

Redwolf Programs

Well allowing multiple reasonable things is not pythonic is it? :p

@RedwolfPrograms is it a6b38027401d461aa28fb45c28f301a1d08209d813f156928d8fd8e6ed2dde8e21c786bea050141ebc1fe24cc920bb94? (sha-384, all lowercase)

Q: Set the sum and product

Given two positive reals \$a\$ and \$b\$, output some positive reals \$r_i\$, such that \$\sum r_i=a\$ and \$\prod\left(r_i+1\right)=b\$. You can assume that it's possible. You can also assume that your float type have infinite precision. Test cases: 2,3 => 2 2,4 => 1,1 or 1/2,(sqrt(57)+9)/12,(9-...

Redwolf Programs

@hyper-neutrino I don't think so, but it's entirely possible I'm using sha384sum wrong

If it looks like a name a human would have it's probably correct

hyper-neutrino

well i got a human-looking name in title case, repeated twice

Redwolf Programs

8:14 PM

Yep, that's it :p

hyper-neutrino

:P

i am in extreme pain

Redwolf Programs

But on the bright side, you know my middle name! :p

hyper-neutrino

i will now use this information for very good and legitimate purposes of course

Wzl

feedback please

Makonede

@hyper-neutrino wut dis?

hyper-neutrino

8:22 PM

@Makonede it's the SHA-384 hash of Redwolf's middle name

Makonede

nice so i know his middle name now :)

Redwolf Programs

If you can break SHA-384 it's all yours :p

Makonede

i have google

Redwolf Programs

Along with billions of dollars in bitcoin and a 550 rep bounty

Makonede

it's in a rainbow table

rak1507

8:23 PM

lmfao

Redwolf Programs

oh lol

rak1507

yeah, 'breaking' the hash is vastly easier than cracking his obscure cryptographic nonsense

Makonede

alright can i have my billions of dollars and 550 rep?

Redwolf Programs

No, only for a general solution :p

hyper-neutrino

bruh. of course it is

Makonede

Redwolf Programs

Should've salted it smh

hyper-neutrino

yeah. didn't think i'd need to salt for smth as trivial as a cmc smh

Redwolf Programs

Not even sure how you got that hash, I can't find anything that returns that using sha384sum

Makonede

use this

dunno what's wrong with your sha384sum

hyper-neutrino

i just used hashlib.sha384(b"...").hexdigest()lol

Redwolf Programs

8:28 PM

I'm doing printf "matthew\n" | sha384sum _/(.-.)\_

Makonede

that works too

@RedwolfPrograms the \n is the issue

Redwolf Programs

Oh :|

Makonede

if you remove it you get the right hash

Redwolf Programs

Don't know what I got the newline thing from

rak1507

I just used crackstation.net

@hyper-neutrino How'd you guess it?

hyper-neutrino

8:38 PM

@user through like 69 different hints that redwolf gave

also because it was just some variant or another on "xor pairs of bytes" so i just kept throwing random things at it

Wzl

@rak1507 it's this nonsense

Redwolf Programs

I'm too impatient to wait for people to solve my puzzles properly xd

@hyper-neutrino In other news, a certain mod has died of eating too many brownies. The food industry is preparing to face a slew of lawsuits.

that's a lie

caird coinheringaahing

@StackMeter Nope. Ær. Takes a list of coefficients (e.g. \$1+2x+3x^2+4x^3+5x^4\$ = [1,2,3,4,5]) and outputs all roots

Try it online! (not very nice roots)

hyper-neutrino

solving for roots of polynomials greater than degree 5 (or was it 4?) doesn't have a good formula right?

i wonder how this does it - newton method or whatever it was called?

or maybe sympy has a built-in :p

Redwolf Programs

Probably just approximation

caird coinheringaahing

It uses sympy

Redwolf Programs

@NewSandboxedPosts That could quite possibly be your last words, bot

user

Whoa, easy with the threats, Redwolf

hyper-neutrino

do we not have a polynomial->roots challenge yet?

i found integral roots and real roots but no general

also this challenge looks like "find roots of polynomial" and I don't think the quartic equation is necessarily relevant (required), but i could be wrong

caird coinheringaahing

If we did have a canonical "given a polynomial, find it's roots" challenge, it'd be good for dupe targets

hyper-neutrino

@RedwolfPrograms i sent this to my friend and he is... slightly less than happy about this :p

@ngn No need for that when you have someone voluntarily giving away their secrets :P

hyper-neutrino

BLOBSPIN, btw

@ngn Well, Redwolf gave away their secrets unprompted, but "or else" can help in cases when people don't do that, I guess. I've also found that being in the presence of a big knife makes people much more honest. Very interesting stuff...

From Construct a polynomial with given roots:

> For the input, duplicate values should be removed and order does not matter. For example, the result with input 3, 3, 6 should be the same as the result with input 6, 3

user

@RedwolfPrograms I suppose I should approach it more scientifically and ascertain exactly why certain phrases and objects make people more willing to be open, but I'm just happy it works :)

caird coinheringaahing

Because we all know that the polynomial with the roots 6, 3 is the same as with 6, 3, 3

user

@user One more handy technique that works is getting one of those Halloween corpse thingies, spraying ketchup all over it, and putting it in a darkish corner. Very effective, gets answers almost immediately when people become aware of it

"enhanced interrogation" :) (i'm not making this up)

@cairdcoinheringaahing But if we do have to make a decision, I'd say yay

hyper-neutrino

"speed-optimized interviewing" but as a serious answer i'd say just use your common sense; joking about stuff is fine but don't make it to the point of potentially being disturbing

caird coinheringaahing

hyper-neutrino

i think it'd be cool to have a way to mark a comment as read which alerts the original poster so that they can remove it

user

Huh, TIL. (also, we're probably on watchlists now :P)

hyper-neutrino

because otherwise to let them know, you have to comment in reply, which then you have to remove once they've read it and removed theirs, and they can't let you know without adding another comment in reply, etc

ngn

@user looks around for drones

user

9:12 PM

@hyper-neutrino Some kind of private upvote thingy, maybe?

caird coinheringaahing

Or even a specific comment that is deleted along with the comment its replying to

hyper-neutrino

something like that, yeah. or some way to indicate to the commenter that their comment has been read and can be removed now

@cairdcoinheringaahing yeah that too. or another idea i had was a way to mark a comment on a post to make it deleteable by the post owner

user

I'm sure there are other platforms that can do that, but moving TNB there would be difficult and not worth it

caird coinheringaahing

@user Comment, not chat

hyper-neutrino

well there's no point in deleting chat messages in that context

they take up just as much space except in the transcript

user

9:14 PM

@cairdcoinheringaahing Oh ok

hyper-neutrino

and it removes context which isn't good, whereas comments can be cleaned up fine
