I use syncthing to sync almost everything across my computer, laptop (occasional usage), server (RAID1), old laptop (powered up once every month or so), and a few other devices (that only get a small subset of my data, though). On the computer, laptop, and server, I have btrfs snapshots (snapper). Overall, this works very well, I always have 4+ copies of my data in 2+ geographical locations.

TOR exit node IP addresses are well-known. If YouTube wants to, they can just block the TOR network.

I took my existing JPEG file, compressed it using JXL, 15% smaller.

Then I decompressed it again into JPEG. The file was bit-for-bit identical to the original file (same hash). Blew my mind!

Directly using JXL is even better of course.

Without UEFI, the boot process is different for each device, requires a custom boot loader, or at least explicit support by the operating system. Is your laptop going to be supported by the distribution you want to use? What about in 5 or 10 years? With UEFI, the boot process is standardized, so it should just work.

Then the editor, all extensions, language servers, etc. are all running as root.
