Mobile Linux is here. Love it. Fear it. Sacrifice yourself to it. There is no escape.
My biggest blog post yet, and it's about running (almost) vanilla NixOS on a (formerly) Android phone! This was 50% fun and 50% exhausting... you solve one issue and another one crops up right away... it was certainly an interesting educational experience.
I'm not explaining any basic technical concepts here, as I'm not a complete noob in phone ROMs and Linux.
