  • What is a “typical VM”?

    Qubes uses the type-1 Xen hypervisor that runs at a similar privilege to the kernel of other OSes. KVM is a type-1 hypervisor implemented as a Linux kernel module. VirtualBox is a type-2 hypervisor that runs in userspace. Of these three, Xen is the most performant hypervisor because virtualization is all it does.

    If by “typical VM” you mean a guest OS running inside a window of the host OS, then Qubes will always come out on top because the graphics pipeline is much less of a bottleneck.




  • This. I’ve had issues at work while imaging classroom computers where some would finish in ~30 minutes and a few would need hours. All of the computers used Cat6 cables. This being a classroom, and students being absolute wankbags, they kept yanking the computers and kicking the cables, so the wires came loose from the plugs. I later used ethtool to debug the slow computers – the switch would only allow 10baseT link modes.



  • Modern, performant computer graphics is an incredibly complex topic full of hacks, workarounds, and edge cases. It’s possible that an update to DirectX/OpenGL/Vulkan caused some edge case interaction between the application and the graphics pipeline to fail somewhere. Updating the GPU driver (mesa, nvidia, amdgpu, or whatever Windows equivalent) could mitigate that failure.

    I remember having to update the Nvidia Windows driver when Cyberpunk 2077 was released to fix an issue related to transparent foliage (transparency is always a pain in the ass to deal with).






  • When you hover the mouse over the thumbnail of a video that contains sponsored content, the preview starts playing (which is another separate gripe I have) and new buttons slowly fade in. One of those is a hyperlink to an information page about sponsorships that takes up the upper half of the thumbnail’s area. The problem is that those buttons are present and clickable as soon as the preview starts, but invisible for about half a second. Clicking on what appears to be the thumbnail might take you to a different page, and navigating back to the front page refreshes the suggestions.
