Irgendwie klingt der Artikel sehr beeindruckt, dass 24h nach dem Börsengang die U-Bahnen immer noch pünktlich fahren. Darauf zu basieren, dass man das in Deutschland ja auch so machen sollte finde ich abenteuerlich.

ChatGPT is not a reliable source of information, I thought that was clear to everybody by now

The processor architecture does not influence RAM usage. (At least not if both architectures are 64-bit)

I mean you’d still expect that critical security fixes would land in testing, no?

A scope groups the initialization visually together, while adding the let app = app; feels like it just adds clutter - I’d probably just leave it mut in that case.

If you’re ever forced to do something the second way, you can also wrap it in braces, that way you end up with an immutable value again:

let app = {
  let mut app = ...
  ...
  app
};

Definitely the second one.

1. It avoids Mut
2. It makes clear that the initialization is over at the end of of the statement. The first option invites people to change some more properties hundreds of lines down where you won’t see them.
