GPT, partitioning

To add a little more detail to <https://wibblement.blogspot.com/2023/07/partitioning-large-drives-use-gdisk.html> : The paritioning scheme that can handle drives larger than 2T is GPT. On linux, use gdisk to partition. The type codes are probably inherited from the old DOS / MBR partitioning scheme and then extended.  Or they are supposed to be GUIDs but, adhoc, have ended up being the above without being standardised. When selecting the type code, if you know what fs will go on there, use:  * for ext4, use 8300  * for exfat, esp for removable media, use 0700 ("Microsoft basic data")

single wire ethernet has two wires and or doesn't exist

How many wires are there in Single Wire Ethernet currently?  Wrong!  There are two. The person whose job it was to count the number of wires miscounted. Single wire ethernet should be possible but does not yet exist.
