Convert YOUR OWN Audible books to MP3 for use on other devices AS YOU ARE LEGALLY ENTITLED TO DO, SO FUCK OFF AMAZON, SUCK MY BALLS
pip install audible-cli # no need to clone, but it lives here: https://github.com/mkb79/audible-cli
audible quickstart # follow the instructions and log into your Audible account
audible activation-bytes # get the activation bytes required to decrypt the file in ffmpeg
audible library list # get the ASINs of all books in your library
EITHER
audible download -a ASINASINA --aax-fallback # download a specific book by providing its ASIN obtained in the previous step
OR
audible download --all --aax-fallback # download your entire library in 'classic' AAX format, which is crackable
THEN
ffmpeg -activation_bytes XXXXXXXX -i audiobook.aax audiobook.mp3 # where XXXXXXXX are your 'activation bytes'

Resize encrypted LVM
IN SHORT:
0. increase size of outermost container (grow qcow2, dd disk to larger disk, etc.)
1. increase size of partition containing the encrypted volume set (cfdisk, fdisk, etc.)
2. unlock encrypted volume
3. grow LVM "physical volume"
4. grow LVM "logical volume"
5. check filesystem
6. grow filesystem
7. tidy up and test.

macOS Spotlight fuckup - not finding applications in /System/Applications, etc.
Run the following in a terminal:
sudo mdutil -Ea
sudo mdutil -ai off
sudo mdutil -ai on
Alternatively, use Automator to create an Application with a Run Shell Script Action containing the above and put it somewhere it's easy to access.

Alpine Linux basic setup
apk add nano udev tmux htop curl sntpc
/etc/init.d/udev start #test
rc-update add udev default
rc-update add local default
# create files e.g. /etc/local.d/rc-local.start
#
## this is peculiar to the picm4 with 200MHz dynamic downclock, which induces several seconds per second of clock drift. Sync with a local NTP server every 5 seconds of server time, ~10-15 seconds realtime, to keep things more-or-less in line.
echo sntpc -i5 -v -d 10.10.11.202 > /etc/local.d/3-fixtime.start && chmod +x /etc/local.d/3-fixtime.start
## NOTE: files apparently have to end in .start or they will not be executed
## NOTE: commands have to exit or daemonize, or 'local' will fail to finish initialization and subsequent attempts to reboot will fail!
