It's not the LoC I care about, it's the logical separation of concerns and testability. Large functions usually do many things which makes them really hard to test. Also, just mashing all the things in a single function is indicative of the author not having a clear picture of what problem he or she is dealing with.
I have been programming for 30 years and, while I don't consider myself a great programmer, I don't like large functions. In my experience they usually fail at clearly expressing intent and therefore make the code a lot harder to reason about. There are, of course, exceptions to this.
The concept is called content negotiation. We used to do this when we wanted to serve our content as XHTML to clients preferring that over HTML. It's nice to see it return as I always thought it was quite cool.
Yup. That’s my experience, too. Also, on macOS the client UI is horrible. It’s slow and I’ve yet to find a way to open local files that it displays in the list of recently synced files.
