This time Tübingen & Reutlingen join forces in the Tübingen library on November 18th.
It'll all be around Linux on the Desktop and daily use.

What looks off may just be hybernate, leaving NTFS harddrives inaccessible by Linux in a Dual Boot scenario.

Enter this and it will shut down for real.

shutdown -s -t 00

I just bought a Keychron K3 Pro and wanted to use it via bluetooth.
Since I use i3, I wanted to do it via commandline instead of a Gnome settings dialog.
This is how to discover a device and pair it via command line:

hcitool scan  # to get the MAC address of your device
bluetoothctl
agent on
scan on  # wait for your device's address to show up here
scan off
trust MAC_ADDRESS
pair MAC_ADDRRESS
connect MAC_ADDRESS
