Oh that’s good then. I think they stopped using whitelists a while ago, so if it is slotted you can probably replace it with anything. Maybe they reversed course on soldered modules then, or perhaps it only applied to some models. I looked into specs of the T16 at some point, and that one had soldered wifi module.
I think the author of the article just haven’t understood how to use the ? operator yet, and don’t think they deserve being called “utterly incompetent” for it. Whether something is a monad or not is not necessarily something a programmer should have to think about on a daily basis IMO.
I just think of rust errors as a tagged enum with either a value or an error. And the ? operator as syntax sugar for returning if something was an error. IMO that simple understanding is sufficient to do error handling in Rust. I don’t think we should gatekeep programming behind some intellectual barrier of whether or not you understand category theory. I certainly don’t understand what a monad is, but I can still write working software and do error handling without unwraps.
