New design brand label: "Sicherheitshalber"

IDEA: First: Only one word: " sicherheitshalber ." printed on T-shirts, pullovers, etc: Different colors, different styles, different fonts - but the same word. The "." (dot) at the end is important ;) In today's times, this word unfortunately seems to be used (and accepted?) a &...

Xubuntu 18.04: Bluetooth OFF by default

I'm very happy that recent kernels support bluetooth chipsets properly out of the box! Hooray! But, I like to have bluetooth disabled after boot - and only turn it on manually on demand.
