qubes os

Backups are good - but if it takes 20+ minutes each time, you just won’t want to do it. This post will teach you to make syncing your backups with other devices automatic and simple.

Remember this post? Back then I said that there was currently no solution for using your GPU inside VMs on Qubes. Well, I found a way. Now cracking/rendering on Qubes might be more realistic than ever.

QubesOS is amazing for security, and equally amazing at making CTFs 10x harder than they need to be. It’s the firewall’s fault.

The reason why audio won’t work out of the box in minimal templates (debian-12-minimal, fedora-41-minimal) is that the package responsible for sending audio from VMs to your host (dom0 or sys-audio), pipewire-qubes, isn’t included in them by default.

When you try to run FreeRDP 3, you will likely get the BadAtom error. This error is vague, and as usual, there’s zero documentation about it that actually helps. Here’s the post I wish existed when I needed it.

The reason you can’t fix this is simple: QubesOS is built on the principle of isolation, and GPUs aren’t designed to meet the strict isolation requirements QubesOS demands because they prioritize performance instead.

Nix is great for keeping your system clean and your sanity slightly intact. But thanks to how QubesOS handles templates and persistence, it’s not quite plug-and-play.
