Linux Desktop on Apple Silicon in Practice

I bought M1 MacBook Air. It is the fastest computer I have, and I have been a GNOME/GNU/Linux user for long time. It is obvious conclusion that I need practical Linux desktop environment on Apple Silicon.

Fortunately, Linux already works on Apple Silicon/M1. But how practical is it?

• Two native ports exist.

The 5-minute backpack demo

Here's what I carry in a Tom Bihn Synapse 19 bag when I travel for 1-to-n days. In general, I optimize for low-weight items, with a secondary focus on reducing maintenance. You can peruse a gallery of pictures, too.

Elixir Debugging Techniques

IO

Old standby for a quick look into your code

IO.puts

Works with anything that implements the String.Chars protocol, AKA the to_string method. Elixir ships with: https://github.com/elixir-lang/elixir/blob/e769afbed96b6b9eee6a4f4ac4a6ea00bc0630f7/lib/elixir/lib/string/chars.ex

IO.inspect

Returns the term handed to it untouched so you can plop it straight in your code
