Dear god please no. This way madness lies. Your idea of “whatever you think works best” is not going to line up with whatever the next person that comes along thinks, and your codebase is about to get all kinds of fucked up.
Thinking code complete is going to save you is naive. Even in languages like C and Java, where it works best, you still need to be able to read and understand the code in context. There’s no hope in a language like Ruby with all it’s meta programming stuff
Yes and no. I agree that camel vs snake or that stupid mNameThing that was popular for a while, doesn’t reeeeeaaally matter, although I would argue that convention over the language still has value. As an example, naming a Java variable with a capital letter would be confusing and annoying to any new devs joining the project, even if it’s a valid identifier. Also it’s handy to be able to look at something in ALL_CAPS and know that it’s probably a static final, without having to check it’s definition. I guess it’s about finding that line between useful conventions and pedantry.
