So I've got a VCR that I can control over serial. If I got a second one, I could stick tapes into them and cross-wire them so that each plays into the other.
I could then set up a program to record from tape 1 onto tape 2, then back from tape 2 to tape 1.
Attach a capture device and I can get video files of each generation.
Then we just watch the generational loss compound.
if you're using Hyper-V & WSL2 your distro state virtual disk image might be wasting 100GB+ of storage space. by default the VHDX grows dynamically but does not shrink if stuff is deleted.
to fix, launch powershell as admin, then:
wsl --shutdown
cd %LOCALAPPDATA%\Packages\CanonicalGroupLimited.UbuntuOnWindows_....\LocalState
optimize-vhd -Path .\ext4.vhdx -Mode full
afterward, you can also update wsl to the pre-release version and enable sparse disks:
@gsuberland As useful as WSL2 is, I can't help but be a little sad. WSL1 was inherently alluring to me because it wasn't a VM - and thus avoided all the resource-management overheads associated with that. Such as this one. :)
