@totallyhuman What does inf() do? (I don't know python, but I thought inf was a number literal)

def inf()

totallyhuman

>>> def inf():
...     while True:
...         yield '_'

thats a function name

Alright, I think I've nearly got LaTeX to SVG down pact...

@ATaco ?

Well converting MathJax to SVG is fairly easy, it's designed for the web.

LaTeX isn't so friendly.

12:34 AM

I did it though! I can now successfully produce SVG from LaTeX.

@ATaco Yay :D

@ATaco :|

It's size parameters are a little off.

> a little off

I'm getting there...

feersum

That's an unusually dimensioned page.

12:38 AM

That's because it's trying to render a proper document, and than just passing that (Somewhat Raw) document to an SVG.

So it's pretty sure we want A4.

Even though we definitely do not want A4.

feersum

But surely A4 is not several times longer than it is wide?

You're really asking the wrong person about this sort of thing.

I don't care why I care how do I make it not

Well I made the BBox a little better, but this fixed exactly nothing.

Discussion of my dungeon of botdom koth

@ASCII-only why did you ask for link ;_;

1:09 AM

Question: this function was given as an example of an indifferentiable function

but that isn't a function at all, right?

for x = 0, it has both 1, and -1

is a function differentiable if it is continous for all real numbers?

@Downgoat no it has neither

@Downgoat wait i don't think so

@Downgoat it is a function (see ^^)

@ASCII-only hm ok I see

CMC: go add the [color] tag to the bunch of challenges that need it

@ASCII-only better question: is the set of functions which are continuous for all real numbers subset of all differentiable functions

@ASCII-only could stand for chat mega challenge

@Downgoat no

hm I see

^ Question: how do you get that (if someone could link me that would be great)

seem like really simple problem

no

1:25 AM

are we back to math

sqrt(2)^2=2. 2^4=16. (sqrt(2)^2)^4 = 16. sqrt(2)^(4*2)=16 sqrt(2)^8 = 16

therefore 8th root of 16 is sqrt 2

can you mathjaxify :3

wait I can do that

yes you can

also please cite me on your homework

wait what is . mean

it is a full stop

it means nothing

or you could interpret it as float but floats don't matter in maths

oh damn I got dark contrast mode tnb again

1:35 AM

@Downgoat \sqrt[8]{16}=\sqrt{2}..?

@ATaco 8th root of 16 = sqrt of 2

Simple.

OK... now look for something even simpler.

@ATaco mine was more extensible...

>:I

I went for simple, true, and LaTeX.

1:49 AM

wait, I have a great idea

I can use that buzzby dance for while the game is playing

too bad noone made it yet ;_;

If your math requires LaTeX to markup, it hasn't been simplified enough.

Requires and Can use are two completely different things.

@ATaco 0/10 too complex

still too complex

Q: Two CnR with same CnR idea

I had the idea to make a CnR where the cops present non-golfed code and the robbers present the golfed version. I found out it was a dupe :( but wanted to know. If you have a CnR challenge and make another with a different task but the same CnR part is it a dupe?

@ATaco That only proves that 16 = 16, which we already knew.

or do we?

I'm fairly certain. ;)

1:56 AM

@Dennis Did you not do highschool algebra

I'm not sure what you mean.

this is how literally all algebra proofs of equality work

unless I missed part of algebra

Starting from the thesis (result you want to prove) and arriving at a tautology only proves that the tautology is true if if thesis is true. This accomplishes absolutely nothing, and if your math teacher taught you to "prove" things this way, you have my permission to hit them with a brick.

user165474

@DestructibleLemon Dennis is a mathematician. I'm fairly certain (and I hope) he's done at least (at very least) university algebra.

@Dennis but the proof is reversible

just read it backwards

2:00 AM

Then do it in reverse.

but then the proof is still entirely valid

if it contains the proof

user165474

how about just do this

user165474

16 ** 1/8 = 16 ** (1/2 * 1/2 * 1/2) = sqrt(sqrt(sqrt(16))) = sqrt(sqrt(4)) = sqrt(2)

@HyperNeutrino Might have come up somewhere before the PhD. ;)

user165474

yes :P

2:02 AM

most of it is proving that sqrt(2)^8 is equal to 16

which is the essence of the proof

user165474

does x ** 1/y == z <=> x == z ** y

(-sqrt(2))^8 is also equal to 16.

@Dennis :O inciting violence

@Dennis ... which makes no difference to the proof

@HyperNeutrino Only when y is odd. Otherwise, you have to take the sign into account.

user165474

Okay. So that doesn't apply here then. Thanks.

2:04 AM

I guess that you rely on the fact that: if and only if zroot(y) = x, then y = x^z

user165474

(sqrt(-2)) ^ 8 is also equal to 16

except when zeroes and stuff

user165474

whoops

user165474

then it does apply here

unless I did something wrong there

2:06 AM

@HyperNeutrino Not sure if we're considering complex numbers.

@HyperNeutrino that is why there is no question mark >_>

user165474

BAH!

user165474

@DestructibleLemon i thought you were just being non grammatically picky

how dare you >_>

user165474

2:08 AM

what did I do

(in case you can't tell, the >_> is intended to mean I actually was and I made it up)

user165474

oh lol

user165474

but still what did I do this time

does anyone really even know what >_> is?

user165474

it's a python code snippet

user165474

2:09 AM

example:

user165474

>>> _=3
>>> 4 >_> 2
<<< True

also do you want to discuss the botdom koth?

user165474

not really, sorry, I'm just kinda hovering around here while ~~being unproductive~~ definitely doing homework

see, this is where the <_< is supposed to be appropriate

> I'm definitely working <_<

for example

user165474

>>> _=3
>>> 2 <_< 4
<<< True

2:11 AM

i need to find a challenge where I can name a variable _ and then use >_> or <_< in my code

@DestructibleLemon You're incorgiable. :P

@HyperNeutrino In a REPL, you don't even need a variable.

@Dennis heel!

@Dennis is _ already a thing then?

user165474

@Dennis ooo so is _ the last value returned?

Yes.

oo cool!

@Dennis -1 whitespace not golfed

@HyperNeutrino That depends on the source's license.

user165474

Great, that's what SE uses too.

user165474

Yay. So how do I use it then; attribute and link?

2:20 AM

That covers the legal part, yes. And since you say the contest is over, I see no problems. Just make the required modifications to fit our format.

user165474

Okay. Thanks :)

what do you think of it?

2:21 AM

But when I found it, all my pet languages were already taken. :/

but you're supposed to outgolf them!!!!11!!!

Believe me, I tried.

@Dennis stop you're ruining the meme

Is anyone here familiar with Intel's Clear Linux?

I put it on my laptop for some reason...

@HyperNeutrino Nice challenge. :) Would have been fun to golf if I had seen it in time.

@DestructibleLemon If only...

What OS should I put on my laptop next? NixOS? GoboLinux? FreeBSD? Gentoo? LFS?

WatOS?

Maybe Qubes

Hell, I should try ESXi

Is that a thing now? OS bingeing

Not really... I should make it a thing

But seriously, what OS should I try out?

(Please don't suggest Solus)

Windows 10

Tried it

Bad

2:46 AM

@HelkaHomba oh, so it actually was a weird out of context message

TempleOS

No customization, no package management, no build tools, driver issues

@HelkaHomba HA. I actually need to do work.

I can't do that with no networking

and constant cultish "messages from God"

um, what happened with avocadOS

By "work" I mean work on things, not serious work.

@DestructibleLemon jQueryOS?

yup

2:48 AM

Went the same way as WatOS (abandoned)

aw man

BTW, check out WatOS: github.com/WatOS/WatOS

wat is watos

As I've said, I'm currently running Clear Linux. It's fast. It's really fast. The problem is that it's a server oriented thing. so there are very few desktop packages for it.

firefox, thunderbird, hexchat, gnome, gimp, a terminal, a few other things

nothing much else

I miss the AUR already

@DestructibleLemon My OS project. Check it out!

watos.github.io/WatOS

but the readme is too short

2:51 AM

clone it, do make then make then make qemu

I tried to make an os once

for the raspberry pi

but it failed because my computer couldn't read all the partitions on the sd card

@DestructibleLemon Refresh the repo please

so I failed before I started

@DestructibleLemon What OS do you use?

osx

then I also got linux

2:54 AM

OSX -1 :P

Can you try out my OS in a VM thing?

Should be bootable through Grub

You would just have to compile it

@MDXF not windows

@Mendeleev Wat OS is that

@DestructibleLemon Ehh... IMO Mac is worse than Windows with VirtuaWin (TTY switcher), MinGW, Cmder, Git and XAMPP

@Mendeleev I could make a partition on my computer for watos

3:00 AM

@ASCII-only was that supposed to be a joke or a serious question?

@DestructibleLemon It does not have disk drivers yet.

@MDXF u wot m8

It only runs in a VM.

@Mendeleev Does it look serious >_>

@Mendeleev um, wah

It's barely an "OS"

3:01 AM

I don't know os words

github.com/WatOS/WatOS

Now that you mention it, pls link to the repo on the website

@DestructibleLemon It doesn't have a concept of hard drives

I'm too lazy to type in the URL

@ASCII-only Will do

@Mendeleev Windows is practically everything nowadays, it's good to learn how to work with it

@Mendeleev but, how does it not be able to read memory of itself?

...Doesn't even have a concept of virtual memory yet

@DestructibleLemon Word salad

> practically everything

u wot m8

? that doesn't even a reply

@Mendeleev Well, it is... Every public computer, every school/college/university computer, it's preinstalled on every computer...

And on some system's it's actually faster than Ubuntu (*gasp*)

3:03 AM

@MDXF I can use it. I just don't want to.

I think we can all agree windows 10 is demonic though

^

Like my laptop is somehow incompatible with Ubuntu, it refuses to boot

and thats preinstalled on most computers

If I use windows at all, it's usually Tiny7 or a server version.

3:03 AM

now

I think

@MDXF What is the problem?

@DestructibleLemon 100% accurate

@Mendeleev Loads at the five stupid dots forever

@MDXF What five dots?

the spinny

@Mendeleev The ones upon boot...

3:04 AM

Have you tried removing the splash to see where it stops booting?

@Mendeleev I can't get into the system to remove the splash

It never boots

how does it work on vm but not work by being in a partition

@DestructibleLemon To me?

@DestructibleLemon Grub can load it. It can't see a disk

@MDXF When in the GRUB menu, remove splash from kernel parameters

@Mendeleev Now I feel very stupid

I've developed a Linux bootloader but I didn't think to edit the basic kernel parameters

3:07 AM

@MDXF Don't.
