Qubes OS is a security-oriented operating system that allows you to compartmentalize your data and activities into isolated environments called "qubes" so that a single cyberattack can't take down your entire digital life in one fell swoop.

Slowly rolling out:
• Public workshops discussing alternatives to Big Tech.
• Private consultation for co-ops, non-profits, and campaign groups on how to make better choices.

It’s time for the people to have control over their own tech - not governments and corporations.

Working at front lines of the IT and having fun there. Been around the Internet since 1992 and still in awe what has become of that little baby. Currently wanted for repeated "Nerd Sniping" on all continents.

Personal interests:

- IT Security
- Computer Games & TTRPGs
- Cycling
- Cooking & Baking
- Books, Movies, TV-Series (mostly F&SF)
- Everything that blinks, has buttons to press and looks remotely gadgetoid

Everything i write, post, tweet, blog or blurp is just my personal opinion and is not the opinion or policy of my employer, my cat or my goldfish.

I post in English and German. Will try to mark each post correctly, but errors happen. Sorry for that.

I appologize if I am not following you back. This happens as my stream is already getting more posts than I can read.
