I don't nearly know enough to understand this but is anyone willing to help me get the thing on the top :>
A MONAD IS A MONOID IN THE CATEGORY OF ENDOFUNCTORS

Typical Computer science vs typical computer engineering

  Sorry about that transporter malfunction, sir! Won’t happen again!
I have to say, I'm getting more and more frustrated by the bad code I have to write due to bad business circumstances.

I want clean, readable code with proper documentation and at least a bit of internal consistency and not the shoehorned mess of hacks, todos and weird corner cases.
- todos
  
  I found a simple trick against this: just remove them. Accept it ain’t gonna happen man.
  
  Well, yes, but the underlying issues still persist, so it's not exactly a sustainable strategy.
  
  Don't just put "TODO". If they're in the final pull request, they need to mention a ticket that's intended to fix that TODO. If you/your team decides it's not important, then remove it and close out the ticket. Either way, you're required to do something with it.
Rust mentioned!
At least the code on the bottom is actual code and not just signatures
Instead of

if let Some(a_) = a{ () } else if let Some(b_)=b{ () } else { dostuff }

you could just use

if a.isNone()&&b.isNone(){ dostuff }

Also if you don't use the value in a match just use _
- Also you can use enums insteas of string literals
  
  I'm not sure how I would go about this in an elegant way since I'm matching the string I get from a message…
- That's a good point, thanks. Maybe I'll go without the if entirely, the (janky) code is still very much in flux ;)
Doesn't that construction only work in categories that also contain their own morphisms as objects since a profunctor maps (Cᵒᵖ × C) → Set and not the same like (Cᵒᵖ × C) → C? Since the category of Haskell types special, containing its own morphisms, so the profunctor could be like (haskᵒᵖ × hask) -> hask? or I just don't understand it.
- Hom functors exist for locally small categories, which is just to say that the hom classes are sets. The distinction can be ignored often because local smallness is a trivial consequence of how the category is defined, but it's not generally true
is this a section of a discord api implementation?
- Almost, but not quite. It's built against Presage
What I hate is when I read a paper and it assumes that I know half of the math already, so there's variables I don't understand that I have to guess at.
