sdkman vs jenv

Jenv is great, but the JDKs have to be manually installed. If you need more than just a couple of them, you'll want to be able to install them via command line, and sdkman provides this capability very cleanly for java. So... is it possible to work with both sdkman and jenv? Yes and no. Some tricks will allow you to tell jenv about the java versions that are managed by sdkman, but setting defaults (using jenv local 17.0 for instance) does not work very well. Time for a cleaner solution. Sdkman provides all of the same functionality, with more power and a slightly different (but equally simple) syntax. I've switched from jenv to sdkman. Here's my cheat sheet.

Setup

Download and install sdkman. Follow the required instructions after installing. Then, run the config command to enable auto_env support.

echo “Installing SDKMAN"
curl -s https://get.sdkman.io | bash

Change TimeZone in Docker containers

With Docker Engine

The timezone of a container can be set using an environment variable in the docker container when it is created. For example:

$ docker run ubuntu:latest date
Sat Feb 27 15:58:32 UTC 2021
$ docker run -e TZ=America/Bogota ubuntu:latest date
Sat Feb 27 15:58:40 Asia 2021

Getting the Raspberry Pi Camera to Work on HASSOS

Enabling the Raspberry Pi camera on HASSOS installations is unfortunately not as simple as connecting the camera and configuring Home Assistant as described at https://www.home-assistant.io/integrations/rpi_camera.

For the camera to work at all, an alternate firmware needs to be loaded when the Raspberry Pi boots. On Raspberry Pi OS (and many others), the alternate firmware is included with the OS installation image, and switching to the alternate firmware is accomplished by running raspi-config and selecting "Enable Camera" from the menu. HASSOS does not include either the alternate firmware or the raspi-config program, so all of the steps need to be done manually.

The steps below attempt to describe the steps that need to be performed. They have worked for me on a Raspberry Pi 3B+ running HASSOS 4.11 through 4.15. If you have a different setup your mileage may vary (but hopefully you'll get enough hints from the below to get it working).

As of HASSOS 6
