I've been running the Ampache Docker image for a while now - generally solid but the upgrade process can be troublesome.  I've had some issues while restarting the container where apache fails to start/continue running.  The fix for this is to delete the /run/apache2/apache2.pid file then restart the container.

The Framework Laptop is a very interesting laptop that is designed to be end user customizable as well as upgradable.

In an effort to enhance my 3D Printing bed adhesion (with my fairly warped bed), I added an ABL to my Creality CR-10.  Initially, I went with a genuine BLTouch from Creality, but wasn't happy with the results so moved to a EZ-ABL from TH3D.  Here are a number of links related to the ABL setup.

This is a beautiful case for a Raspberry Pi 3 7 inch touchscreen (and Pi).  Unfortunately, the center section hasn't been updated for a Raspberry Pi 4, however, in my case, I had an existing RPI 3 (and 3.5" touchscreen) that I needed to upgrade to a larger screen to handle OctoScreen/OctoPrint.  There were some comments on Thingiverse that it was for the "older" 7" touchscreens while the newer ones were upside down and that does seem to be the case, however, it's easily handled by setting the rotation in config.txt.
