I have had a horrible experience with JLPCB. Paid 150 euro for 5 boards, only 3 of them working, got 8 dollars coupon for next purchase.

That depends. Does the keyboard on the thinkpad work?

diceware is an online as well as command line implementation.

These are great, thank you for sharing them!

UEFI standard requires a FAT32 partition. It is usually a first partition on disk, 500MB in size. The linux kernel to boot, together with initrams disk can be placed in the root partition, usually ext4 or btrfs, or it can be placed in uefi partition. Limine will only support booting the kernel from uefi fat32 partition to avoid having to support ext4 and btrfs filesystems. The root partition will still be ext4 or btrfs, the code to mount it would be in kernel or in initramfs. Edit: size of uefi partition

I don't think there is a free software digital video system. Closest would be OpenVTX, that's analog.

Can I follow them from my programming.dev account?

Yes, you can delete arbitrary snapshot without other snapshot being affected. You can even delete the original subvolume and the snapshots made from it would be still accessible.
