I've been making a hobby app with GTK Rust in GNOME Builder for Pinephone and eventually Librem 5.

App runs well on Pinephone but building Rust GTK App on Pinephone takes forever. I did it once out of curiosity.

Luckily qemu cross compiling is easy to do on laptop and SCP it to phone, with native Linux SSH and root on phones it is refreshing.

Cannot wait for Librem 5 to get shipped, it's a lot more powerful than Pinephone, but I'm super happy to be experimenting on the future of Linux phones and convergence, regardless of where it ends up going.
