hi everyone

Simply Beautiful Art

heyo

muddyfish

Hey

HyperNeutrino

rewriting the interpreter for proton is more of a pain than I thought originally lol

muddyfish

I've been thinking about rewriting the core for Pyke but I really don't want to just for easier auto generating explanations

ATaco

Re-writing languages hasn't ever ended well for me.

I started doing that with RProgN and now RProgN2 exists which is almost a completely different language.

(^^ the story of Positron and Proton lol)

ASCII-only

@ATaco 100% sure this would happen if I ever made a Charcoal 2

also kinda the story of Cheddar/VSL

Christopher 2EZ 4RTZ

Did you know by going from $\text{(-2)^x=4}$ you can solve for i and get $\text{i=0.47}$?

ASCII-only

What. Where did $i$ come from.

Christopher 2EZ 4RTZ

Exactly

Simply Beautiful Art

23:14

Wait what?

ATaco

I have my doubts, but I'm no mathematician.

Christopher 2EZ 4RTZ

HyperNeutrino

Can't read that at all.

Simply Beautiful Art

Same

Christopher 2EZ 4RTZ

Bad picture

ATaco

23:17

Perhaps you should write it in latex.

Q: Output the simplified Goodstein sequence

A number is in base-b simplified Goodstein form if it is written as b + b + ... + b + c, 0 < c ≤ b The simplified Goodstein sequence of a number starts with writing the number in base-1 simplified Goodstein form, then replacing all 1's with 2's and subtracting 1. Rewrite the result in base-2...

Christopher 2EZ 4RTZ

@ATaco how do you do log base a number with that?

Simply Beautiful Art

@Christopher2EZ4RTZ \log_{-2}(4)

ATaco

@Christopher2EZ4RTZ ^

Christopher 2EZ 4RTZ

How do I add newlines to it?

To space out my math

ATaco

23:19

I like this Squared Pyramidal numbers challenge.

Simply Beautiful Art

I believe your problem is your definition of $\log_{b}(a)$

ATaco

Two backslashes.

\\

Simply Beautiful Art

You get the idea xD

Christopher 2EZ 4RTZ

And showing division?

ATaco

I used Threead for the first time in I think half a year.

Simply Beautiful Art

23:21

$$(-2)^x=4\\ x=\log_{-2}(4)\\ x=\frac{\ln(4)}{\ln(-2)} \\ x=\frac{\ln(4)}{ \ln(2)+\pi i}$$

HyperNeutrino

\div I think? You can also use \frac{num}{denom}

Simply Beautiful Art

I believe this is basically what you did

Christopher 2EZ 4RTZ

Very close

HyperNeutrino

Is it just me or is ln(-2) not a thing?

Christopher 2EZ 4RTZ

It is

ATaco

23:21

HyperNeutrino

Oh wait, complex powers?

Christopher 2EZ 4RTZ

But instead of x it is 2

ATaco

Boop, Image.

Christopher 2EZ 4RTZ

Yeah and $\text{x=2}$

Simply Beautiful Art

So yeah, the problem here is your definition of ln

And e^x

Christopher 2EZ 4RTZ

23:22

How?

They are both the normal definitions

ATaco

desmos.com/calculator/ijuz3alahc

Simply Beautiful Art

Nah

ATaco

Well that was easy

Simply Beautiful Art

Think of it more simply like this

Christopher 2EZ 4RTZ

Also can I get the raw text for that mathjax?

Simply Beautiful Art

23:22

(-1)^x = 1

x = log_{-1}(1)

^ This doesn't work

Christopher 2EZ 4RTZ

CMC: Design a Turing Tarpit with exactly two operations, each of which are the inverse of the other and both of which are needed for turing completeness

Simply Beautiful Art

Since x can be any even integer

ATaco

@StevenH. Chat Mega Problem?

Simply Beautiful Art

So as you can see, log at complex bases of complex numbers is generally ill-defined.

Steven H.

23:23

Chat Mega Challenge. Jeez, get the acronyms right.

HyperNeutrino

So then they'd have to be non-abelian operations

Does anyone have any good resources for learning the beginnings of LaTeX? I think it's something I should get to know

Christopher 2EZ 4RTZ

@ATaco can you send me the laytex you used for that image?

Simply Beautiful Art

@NewMainPosts Say, does anyone think that adding in the example expansion for 1 and 2 would be helpful?

(-2)^x = 4 \\
x = \log_{-2}(4) \\
x = \frac{\ln(4)}{\ln(-2)} \\
x = \frac{\ln(4)}{\ln(2)+\pi i}

@Christopher2EZ4RTZ ^

ATaco

23:35

Yeah, that's it.

Christopher 2EZ 4RTZ

Thanks

Hi, Python question: I want to override __getitem__, but I also want to be able to access self.ident variables set in the __init__ function. How do I do that without blowing the stack?

muddyfish

Properties might be useful instead of getattr

HyperNeutrino

Can you elaborate on "properties"?

hold on nvm figured it out; I don't need to override __getattr__ but I did, which caused the problem lol

muddyfish

stackabuse.com/python-properties

HyperNeutrino

oh cool!

thanks!

wait so @property does things lazily, not calling the function each time, right?
