I went looking for the implied ‘A’ language but couldn’t find it. Did find this though:
https://en.m.wikipedia.org/wiki/List_of_programming_languages

Surprising how many single letter names there are.

You should read this page: https://github.com/linux-surface/linux-surface/wiki/Installation-and-Setup

It’s very detailed about what to do to get stuff working (on lots of distros), and what currently isn’t working (see camera support etc)

I took a look in the past but deemed it too much of a compromise at the time for what wasn’t working.
