Resetting system state in between luaunit tests
I have a bunch of automated tests that end up modifying system state. I'm manually unwinding state changes inside my `teardown()` function however it's very bothersome to do this and I have a feeling not all changes are being reset.
My question is: is there a nicer way to reset state during tests? I suppose I could run a separate lua process for every single test but hoping there is a cleaner solution?

Phase angle Vs Torque for IPM Motor in FEMM
I have a IPM motor modeled in FEMM and I am trying to get a graph of phase angle Vs torque.
I have been unable to find any sample code for this, does anyone have any suggestions on where to start?

Problem generating consistent heightmaps using simplex noise

I'm trying to generate a 2d terrain from a heightmap created by simplex noise.
The use case is a map that is endlessly traversable in all directions,
so I have copied the source code from this tutorial project [https://www.youtube.com/watch?v=Z6m7tFztEvw&t=48s](https://www.youtube.com/watch?v=Z6m7tFztEvw&t=48s)
and altered it to run in the Solar2d SDK ( don't think my problem is API related )
Currently my project is set up to create 4 chunks, my problem is they have incosistencies. When generating the heightmaps with 1 octave they are consistent, so the problem is caused by having multiple octaves, but I can't figure out why or how to work around it.
I know this is quite an extensive ask, but I'm hoping someone here has experience working with noise and could offer some suggestions. Any pointers are greatly appreciated.

Is is possible to test if value is boolean while using only what is thought in chapter 1 of "Programming in Lua, 4th edition"
Exercise 1.6 of the book "Programming in Lua, 4th edition" asks how to check if value is a Boolean without using type. I came out with (value == true or value == false) and it works, but it uses == which has not been introduced so far.
When I learn (or relearn/revise) something in a book and do the exercises, I am very careful to only use what has been covered so far but I don't think that's possible in this case, am I missing something?

Intercept and count JMS package size
Hi there, how would u guys count the packet size of a JMS TextMessage object.
I am intercepting a JMS message over TCP and I’d like to count the bytes of the message stream. Such that once it hits 10 bytes, I want to fire an if clause to break the loop and only forward the 10 bytes up to JMS.
Any ideas how I could count the bytes?

I'm not sure how much of it you'll need to see to get a grasp on it here, but I'm trying to get the buttons changed off of my mouse onto 'rshift' and 'rctrl'. I've tried to change it over to IsModifierPressed but I just cant figure it out. Please get back to me if you can help, I've been up trying to solve this on my own for 4 hours and no research is paying off. Thanks.

Decryption / FXAP
Hi! I have obtained a FiveM Script which I need urgently to work but I'm scared to try it because it might be malicious. The problem: I can't check the code because it is encrypted. Pretty sure it has something to do with with FXAP because it says on the top as the only readdable code and there is also a .fxap file. Any idea/help? Rest of the files arent encrypted and look good. Thanks in advance.

I have been using Lua for many years now as it is my goto language.
However, I have never understood the purpose of userdatas.
From what I know, it sort of works like a table, where you can set a metatable to it and extend its functionality.
So what is the purpose of userdatas in Lua?

Question regarding Lua.
So I'm 16 now and planning on studying CS. So I thought I should start learning a language to help me later on at University. But me and my friend were talking about Making a Roblox game. Roblox uses the language Lua. The problem is I wanted to learn a coding language that would help me in the future. And I just wanted to know if me learning Lua would help me with other coding languages, or it's just completely unrelated to anything.
