    Thanks to Crowdstrike I know that at least the checkouts in shops and some ATMs here use Windows 8 or newer, because of the new blue screen design (don’t remember if they had the QR code, which would mean at least Windows 10)


  • I don’t think The Guardian is wrong here, see this passage from the article:

    Comer has sent 16 letters to former Biden White House officials requesting transcribed interviews, NBC said. Metadata analysis showed that all appeared to be signed with a digitally inserted signature. Further letters requesting testimony from the White House physician Dr Kevin O’Connor and Anthony Bernal, a senior aide to former first lady Jill Biden, were also signed with digital images, NBC said.

    He did not use cryptographic signatures, but images of his written signature, which I think is pretty similar to using an autopen (albeit probably much easier to detect)




  • My theory for why it created copies: The files you listed look like they are all subdirectories from /dev, which is (usually) a separate filesystem. When you try to move a file or directory across filesystems, the OS can’t just change the link, it has to actually copy the files and then remove the original. As a directory is a set of links to files, and the copies are different files, directories are just newly created with the same name in the new location instead of copying the directory filesystem entry. It looks like mv creates these target directories, before it checks if it actually has permission to remove the source, but checks file permissions, before it copies them




  • Regarding snapshots, I use a setup, where at the root of the btrfs partition I have the subvolumes “rootfs”, “home”, and a directory “snapshots”. I can boot into a snapshot by changing the mount options for the rootfs in the kernel command line, e.g.setting subvol=snapshots/rootfs-yyyy-mm-dd.

    The only difference between a snapshot and a regular subvolume is that snapshots are readonly by default, you can keep a writable copy of a snapshot beside it for recovery purposes, if you need it. As long as nothing is written in it, it shouldn’t use any significant extra space.
