@TùxCräftîñg That's a retun statement in lua, concatenating looooots of things

12:16

@TùxCräftîñg oh, la réponse

@TùxCräftîñg "à" si l'on parle d'être correct

Katenkyo

@LeakyNun Still some bugs, seems like it's modifying the value of S during the concatenation because of the recursion

TùxCräftîñg

too lazy to write à

and i think si l'on veut être correct is more correct

Leaky Nun

@Katenkyo because of your recursion? I thought it returns a string

What's your terminating condition?

@TùxCräftîñg I was trying to say "talk about"

Katenkyo

@TùxCräftîñg si l'on veut être exacte is even more correct

TùxCräftîñg

exact is more correct

because in plural words are at male form

Leaky Nun

12:19

@TùxCräftîñg quoi?

Katenkyo

@LeakyNun it does, but S have a certain value in the first half of this concatenation, and an other one in the last. terminating condition is n=1 which is when we print the center

@Katenkyo That sounds unhealthy

Leaky Nun

@Katenkyo d'accord, edited

Katenkyo

@LeakyNun Otherwise, that's a good translation!

Leaky Nun

12:37

@Katenkyo merci

@Katenkyo I translated this:

> Mes belles que j'aime tant,
il suffit d'un seul regard
et d'un amour délirant.
C'est peut-être le départ.

to this:

> My sweethearts whom I love very much,
It suffices to have a single glance from you.
And if we have a crazy love,
Maybe this is the start.

but I wonder if "un amour délirant" goes with "il suffit" instead

Katenkyo

@LeakyNun Hum, I may have overlooked a point there

My sweethearts whom I love very much, is okay

It suffices to have a single glance from you and if we have a crazy love, isn't really the essence of it

Leaky Nun

what does it mean?

Katenkyo

My sweethearts whom I love very much,
A single glance from you
and a crazy love suffice.
It may be the start/beginning

Leaky Nun

of what?

Katenkyo

There's 2 sentences over 3 part in the strophe

the first sentence is:

Leaky Nun

12:44

the start of what?

Katenkyo

> Mes belles que j'aime tant,
> il suffit d'un seul regard
> et d'un amour délirant.

@LeakyNun The start of a love story

Leaky Nun

@Katenkyo where's "love story"?

Katenkyo

There's 2 part in this sentence
`Mes belles que j'aime tant, `
and
`il suffit d'un seul regard
et d'un amour délirant.`

Mᴀʀs Uʟᴛᴏʀ

Wouldn't delirious be a more direct translation of délirant?

Katenkyo

@LeakyNun That's sub-text ^^

Leaky Nun

12:45

@Katenkyo alright, edited.

Katenkyo

Mes belles que j'aime tant is well translated, but il suffit.... amour délirant is more like It suffices to (have a single glance && have a crazy/delirious love)

That's 2 conditions needed, and when met : C'est peut-être le début.

huh syntax of the year

quartata

Looks like it parsed correctly, no?

TùxCräftîñg

yes

i have unintionaly maked it golfy

quartata

Well Haskell has you beat :P

f x y = x + y

TùxCräftîñg

D:

f = {x y|x + y} so

huh still longer

zyabin101

Alright then, after 7 days, no one has joined the Remaining Bytes.

Which confirms, yet another time, that everyone has their attention at everything except me.

TùxCräftîñg

16:14

the Remaining Bytes?

ah trash

or ¯\_(ツ)_/¯

zyabin101

A Google Spaces Space I made for PPCG.

TùxCräftîñg

ok

link?

zyabin101

@TùxCräftîñg I'll have to safely encrypt it so that no one could get to the Space without my permission.

TùxCräftîñg

k

zyabin101

You'll need your chat No. and a salt.

Choose a salt.

TùxCräftîñg

16:16

huh

Business Cat

Epsom is pretty nice

zyabin101

@TùxCräftîñg A salt in this case means an arbitrary string.

TùxCräftîñg

so worder ftw ¯\_(ツ)_/¯

how can i send you the salt?

zyabin101

@TùxCräftîñg encipher.it

Dr Green Eggs and Iron Man

What are your favorite vim color schemes? (Both for gvim and console) I'm looking for new ones.

zyabin101

16:20

@DrGreenEggsandIronMan exempt from both

TùxCräftîñg

i am using the default

@zyabin101 and what i do with this?

zyabin101

@TùxCräftîñg I already chose the salt, the salt is "w*****". (Censored because someone could intercept it if I didn't.)

TùxCräftîñg

ok

quartata

@Dennis Can you pull CG? (Ignore the failing Travis build)

zyabin101

@TùxCräftîñg encipher.it?DUSQ

Multiply the salt by a hexagon.

^ Clue for the encryption password.

TùxCräftîñg

16:29

i have no brainfucking idea of what it can be

quartata

If this is your attempt at a key exchange #youredoingitwrong

TùxCräftîñg

^

quartata

Just trade public keys, encrypt the message with your private key and their public key

TùxCräftîñg

^

zyabin101

@quartata The service I'm using uses symmetric keys, and I don't have access to a computer to RSA encrypt it.

@TùxCräftîñg ^

TùxCräftîñg

16:32

ಠ_ಠ

zyabin101

@TùxCräftîñg Let's try again with JSEncrypt. @_@

TùxCräftîñg

@_@

quartata

@zyabin101 You can easily RSA encrypt things by hand

At least a very crude message

TùxCräftîñg

@quartata huh wat

encrypt RSA by hand

Martin Ender

Do the three axis-aligned planes in 3D have a better name than "axis-aligned planes"? (that is, the xy-plane, yz-plane and zx-plane)

TùxCräftîñg

16:35

y u know that we are humans

quartata

@TùxCräftîñg I think you grossly overestimate the complexity of the actual math

TùxCräftîñg

¯\_(ツ)_/¯ when i saw prime number i immediatly give up

zyabin101

@TùxCräftîñg So, you generate a key pair with travistidwell.com/jsencrypt/demo, return me the public key and I try to encrypt the link with the public key and you try to decrypt the link with your private key.

TùxCräftîñg

zyabin101

@MartinEnder Sorry, pinged the wrong person. >_>

quartata

16:38

@TùxCräftîñg M^e mod pq

zyabin101

@TùxCräftîñg Seems I can't edit the key pair in the demo.

TùxCräftîñg

¯\_(ツ)_/¯

quartata

@MartinEnder Hm

Dennis

@quartata Will be home in roughly 5 hours. I'll pull asap.

Martin Ender

@zyabin101 so you figured the best solution would be to ping that person again? ;)

(no worries, happens...)

quartata

16:40

@Dennis All right

zyabin101

@TùxCräftîñg Suggest an online RSA encryption method?

TùxCräftîñg

¯\_(ツ)_/¯

Dennis

@Zgarb Will be home in roughly 5 hours. I'll pull asap.

zyabin101

@TùxCräftîñg Okay, so just share the link in plain text?

TùxCräftîñg

what link?

zyabin101

16:42

@TùxCräftîñg Invite link for the Remaining Bytes.

quartata

@MartinEnder I don't think there's any notable other names

TùxCräftîñg

k

zyabin101

That was my try. @TùxCräftîñg Did you copy?

TùxCräftîñg

yes

Nathan Merrill

bah, language design is difficult.

Dennis

16:44

@NathanMerrill I do. The changes are minimal most of the time.

zyabin101

@TùxCräftîñg Okay, then run the link (you need a Google account) and see what happens.

TùxCräftîñg

i am on the homepage

Nathan Merrill

cool

quartata

@DrGreenEggsandIronMan Painful

I think I could do the regex better but I don't think I can beat V here...

maybe next time

zyabin101

@TùxCräftîñg Cool, welcome to the Remaining Bytes!

quartata

16:46

Hmm, there was another challenge I was gonna take a look at

zyabin101

@Tux Acquaint yourself in the Spaces help center.

Nathan Merrill

If you consider the interfaces between an immutable and a mutable queue, they are, unfortunately, different. mut_queue.pop() should return T, while immut_queue.pop()should return Queue<T>

unless, you make all mutable queues return themselves (requiring a peek)

The other option is to have some magic syntax that says "update my reference"

and have immut_queue.pop() return T

but every time it'd return the same T, unless you updated your reference immut_queue&.pop()

and I have no idea what the function looks like

quartata

sre_constants.error: look-behind requires fixed-width pattern

right I forgot Python regex sucks

Well, guess I'll make my own flavor? ok

TùxCräftîñg

regex sucks in general

but it's useful

LegionMammal978

^

quartata

16:56

@TùxCräftîñg This would have worked in .NET regex

TùxCräftîñg

¯\_(ツ)_/¯

LegionMammal978

also ^^

quartata

I can use \K though

Wait, does Python regex have that?

TimmyD

@MartinEnder Cartesian planes?
