I wanted to embed an image to my binary and used the "include_bytes" macro. The GUI library I wanted to use only accepts [u32] for input and the said macro produces only [u8].
How do I convert a [u8] to a [u32]? I've seen some in the internet but the explanations are a bit too technical for me (I'm only self-taught). There were several options that I saw like bitwise and a method in "u32" from the standard library. Anyone can give an actual code on how to do it? Like study it from there in case I will need it for other files in the future. Thank you. I almost always just understand things via code coz I'm not aware of many technical terms, algos, etc.
using .map(Into::<u32>::into)
fn main() {
assert_eq!([0_u8, 1_u8].map(Into::<u32>::into), [0_u32, 1_u32]);
}

I have a question that may seem silly, my english is not very good, I often don't know how to name variables or methods.
For example, There is a method, its function is to open a modal for creating users, I will name it openCreateUserModal, Its corresponding English sentence is "open create user modal", I think this is not grammatical in English because there are two verbs. Would it be better to name it openCreatingUserModal？Or the method name does not need to follow English grammar?
I want to get a rule for naming complex methods
openCreateUserModal is perfectly fine. It clearly conveys what the function does. Following the rules of english grammar is not important in this context as long as the function name clearly indicates what the function does.
Since you haven't mentioned any particular language, below is a source c# naming conventions. The principles are the same for any programming language.

I don't know what to search for about this kind of design. I will use it on my app for the empty state, but I'm getting trouble searching. hope you can help me guys. Thank you :)
Well the design type is "minimalist" or "modern" I'd say. If you are looking for a specific file format or something I think you'd be looking for SVGs (Scalable Vector Graphics).
From trial and error, the best search queries are along the lines of "Abstract Minimalist" or "Contemporary Art". Agreed, it is difficult to express to a computer what image you are trying to find.

When creating a webserver in golang, is there any specific reason why JSON data would be represented as a MAP over a STRUCT or vice versa? ..or is this decision based purely on user preference ?
I think this discussion could go either way but the advantages of using structs vs maps are that structs give you an idea of how the schema should look like whereas a map leaves the schema open-ended.
If you use structs, developers who look at the code will have a clear idea of what parameters you're expecting for the API or how the response of the API may look like without digging further into implementation detail. On the other hand if the requests or responses were maps, they would have to look at the implementation detail to see what keys and values are being assigned. Hope this helps!

So I have this line:
if self.company_changed?
And it works fine but this detects if the company has changed on the object. I need to know if the database value has changed and not if the value in memory has changed. So I tried this:
if :company_changed?
This seems to work in debug mode when I only execute the one line. If I let it run, it fails in testing on an infinite loop.
My question is what can be used in ruby to check to see if the column value has actually changed.
I'm pretty sure you're actually talking about ActiveRecord. In which case, you'd need to re-fetch the record to see if the value has changed in the database.
self.class.find(self.id).company != self.company
A general purpose method for this might be something like:
def attr_changed_in_db?(attr)
self.class.find(self.id).attributes[attr] != self.attributes[attr]
end
There is an excellent screencast on this by the great Ryan Bates.

I have a project I am working on that is written in Python. The variable/class/function/everything names do not adhere to the Python style guide.
example: a variable might be called myRandomVariable instead of the proper: my_random_variable
My question is, is it worth combing through all the code (around 10,000 lines) to fix all the naming convention problems or should I just say, 'the heck with it -- it works'?
Thanks
Edited to give example
Just because there is a Python style guide, it does not mean that all Python code should adhere to it. The most important thing to consider in a code base is that it's consistent with itself, at LEAST on a per-file basis, preferably across the project!
I would vote for your second option. They are just styles. Everyone will have their own style. You don't need to be in compilance with defined styles to say your product is great.
