I use Ubuntu (20.04 LTS, now 22.04 LTS) as my main operating system. Some background on switching from OS X to Ubuntu here: https://github.com/bjohas/Ubuntu-keyboard-map-like-OS-X. I don't really use Windows at all, and I am surprised with how the intial setup of Windows has gone wrong for some of my friends (missing dlls, etc etc). However, there are a few 'OS X / Windows only things' and with a larger SSD on a new laptop, I thought I'd preserve Windows. E.g., 'OS X / Windows only things' include Adobe Creative Suite, as well as using Oculus/Meta Quest 2 via a PC connection.

Dual booting Ubuntu and Windows with encryption (for Ubuntu 22.04 LTS)

I used these instructions to dual-boot-ubuntu-and-windows-with-encryption.md https://www.mikekasberg.com/blog/2020/04/08/dual-boot-ubuntu-and-windows-with-encryption.html

Dual-booting with encrypted storage should not be this hard in 2020 2022.

Advantages Docker:
* Same config for development and production
* Manage dev/prod environment cleanly only via docker-compose files
* No configmanagement necessary - just pass environment variables

Disadvantages Docker:
* Rebuilding images takes long on Raspberry PI
* Building ARM Docker images on non-Raspberry PI build host is complex
* Cannot host private Docker images on docker hub for free - need to run own Docker image hub

# raspbian stretch lite on ubuntu

### You can write the raspbian image onto the sd card,
# boot the pi so it expands the fs, then plug back to your laptop/desktop
# and chroot to it with my script 
# https://gist.github.com/htruong/7df502fb60268eeee5bca21ef3e436eb
# sudo ./chroot-to-pi.sh /dev/sdb
# I found it to be much less of a pain in the ass and more reliable
# than doing the kpartx thing
