I'm very new to the language and I'm very confused on some things. Coming from imperative langs, I'd assume that modifying tuples is very fast since they're basically just vectors. Unfortunately, they're also immutable like every other data structure in the whole language. So, if I want to make, say, a Canvas data type that holds all my pixels in a 2d data structure, is there literally no way to make it even if a little more efficient than just making a new one every single time I update a pixel? Even if I made it a 1d data structure, is Elixir just the wrong tool here?

i used to be able to type out ^(superscripts) and `code blocks`, well not anymore. While asterisks convert to italics, \*backslashes\* also stay, which is just ridiculous.

After looking up how guard clauses work, I found this snippet:
defmodule User do
defstruct age: 0

defmacro is_kid(age) do
quote do: 6 < unquote(age) and unquote(age) < 12
end

defmacro is_teen(age) do
quote do: 12 < unquote(age) and unquote(age) < 18
end

defmacro is_elder(age) do
quote do: 60 < unquote(age)
end
end

defmodule Greeting do
import User

def greet(%{age: age}) when is_kid(age), do: "Hiya"
def greet(%{age: age}) when is_teen(age), do: "Whatever"
def greet(%{age: age}) when is_elder(age), do: "You kids get off my lawn"
def greet(_), do: "Hello"
end
It feels really... unconventional. Obviously, that's my subconscious speaking after so much experience with imperative languages, but is this really the only way to introduce my own guard functions? Say I need some kind of Vec3.is_normalised/1 method, is there no other way to write it other than by quote-unquote: quote do: unquote(Vec3.magnitude(v)) == 1?

do you think comments should be concise about what exactly the function does and not how it does it, or is it good to have in-depth explanations like this?

I'm not familiar with jailbreaking scene, I just have an old console and I heard that jailbroken ones have great second hand value. I have version 11.02 so the webkit should work; the tutorial showed goldhen i think it was called? is this one the best to get, or is there something better?

Everyone seems to have it, but it doesn't add much use for electricity. Liquid fuels are extremely useful, but that's just a small part of the addon.

filled a 10000 block hole in the overworld with lava. the hose pulley said "infinite". i immediately reroute all my lava supply to drain from my limitless hole, and immediately it is no longer limitless. did i do something wrong?

The dictionary states that "celsius" is pronounced as /ˈsɛlsiəs/, which is what I usually hear from most people. However, I've heard a nuclear engineer from the US pronounce it as /ˈsɛlʃɘs/. How common is this pronunciation, and what regional variations may use it?

why the FUCK does the same motion i did for so long now do something COMPLETELY different

i can't reach for ANY buttons now and all the sliding directions are completely messed up
