Elixir installation guide

Version numbers should be the ones you want. Here I do it with the last ones available at the moment of writing.

The simplest way to install elixir is using your package manager. Sadly, at the time of writing only Fedora shows the intention to keep its packages up to date. There you can simply sudo dnf install erlang elixir and you are good to go.

Anyway, if you intend to work with several versions of erlang or elixir at the same time, or you are tied to a specific version, you will need to compile it yourself. Then asdf is your best friend.

Commit, clone a container

To 'clone' a container, you'll have to make an image of that container first, you can do so by "committing" the container. Docker will (by default) pause all processes running in the container during commit to preserve data-consistency.

For example;

docker commit --message="Snapshot of my container" my_container my_container_snapshot:yymmdd

Using Apple’s Aerial Screensavers on Ubuntu After coming across the [Aerial] (https://github.com/JohnCoates/Aerial) screensavers for Mac, and installing them, I decided that I had had enough of the graphics-demos of my Ubuntu Precise system. I hope to provide a simple guide on how to add them to your setup as well.

First, you need to install xscreensaver (for example with aptitude, but your distro should have it):

sudo aptitude install xscreensaver
