QubesOS – A reasonably secure operating system

I highly recommend it. Since I tried it a couple of years ago I can't imagine working without it. Examples of things that I can't imagine doing in any other system:

  - curl|bash or similar 
  - pip install, npm install etc
  - run any random github project
  - sudo install the drivers of my Brother printer
  - install zoom
  - plug random cheap USB devices to eg update their firmware

In addition to that you can easily restart frozen VMs without restarting the whole system, keep backups of your VMs (very handy when restoring or changing PCs), reinstall some VMs if you mess up, etc.

Not suitable is for GPU intensive work, though (although if you have a dedicated GPU in theory you can assign it to a VM).

Ashamed to say but I do all these things on my main OSs for ~15 years and I never had any problem (IIRC). Yes, I'm not huge on security and I realize what this could do, but I figure the chance is as big as getting it through a channel I don't expect.
