@mmin @jonne A long time ago I volunteered for medical research where magnetic imaging was used to get images of the veins in my legs. When imaging started, the machine started making ticking sounds, like a clock. Then the ticking stopped and I yelled to ask If it was over. The doctor in the adjacent room cursed; the Windows machine controlling the imaging equipment had crashed.
@mmin It's the most used operating system, but you can't use it for anything important, because you can't trust it.
