Both can go faster than light and “therefore” break through dimensional thresholds or go backwards in time; at that point actual measurement is kinda pointless. However, Flash is bound to the Speedforce (of whatever dimension/timeline/etc he’s in) and when that’s shared with any other speedsters, he becomes less capable. Sonic does not seem to share this “weakness” therefore would be considered faster.
This is the same argument for why Superman is actually faster than Flash, too. And ignores the use of chaos emeralds.
This has been on my mind, I have yet to do it but the implementation seems trivial.
You can use typical luks full disk encryption with a password. Luks actually has five password slots. Passwords do not have to be actual text, they can be a file or even part of a file.
So my idea is, buy some really cheap, low profile USB flash drives and store some seemingly innocuous data like cat pictures or public domain books, IDK and it doesn’t matter what the actual data is. Use full disk encryption and set a regular password, then add a second password that is a file or part of a file that lives on the flash drives, and have it set up to look for that file on boot as an option for unlocking.
Now the disc is fully encrypted but will boot/reboot without interruption as long as the flash drive is installed. You can remove the flash drive when you’re feeling paranoid, or even better only install it when you are going to be away for a while. If you leave with the machine having the flash drive but are feeling worried, you can remote into the machine and edit / delete the file or just clear the key slot from Luks.
That’s what’s been on my mind, anyway. I think the typical suggestion/solution is to just use drop bear and remotely unlock using that, or don’t use full disk encryption and selectively encrypt your data instead (partitions or userspace encryption).
I’m not going to proofread this so I hope it makes sense
