Link: ARM support in Linux distributions demystified
ARM support in Linux distributions demystified (via) is just what it says in the title. Since I only just recently learned about things like 'Aarch64' in the process of writing this entry, all of this was timely and useful. It definitely taught me things about ARM floating point and architectures that I didn't already know.
(The discussion on lobste.rs has some useful additional information about stuff.)
