Well, the routes might manifest somewhere as files, but I don’t expect anyone to be able to viably parse them without commands like ip
or ifconfig
(or know where the files even are).
Some devices (like disks for example) are very straightforward to use as files, while some other special files (like USB devices) are so weird/ugly to use that everyone uses tools/libraries to access them (like libusb).
This is very off-topic, but there’s a great talk by Benno Rice that talks about this (among many others): https://youtu.be/9-IWMbJXoLM
Oh wow, cool story about Yasuke. Is that where Yakuake got its name from?
Among my friends, dark mode users hugely outnumber light mode users, I really don’t have any apps that struggle to support it. LibreOffice used to be really bad, but I don’t really edit documents anymore, so I don’t use it often, but when I do, I don’t see issues (although the document background is white, because paper, so the contrast is a bit weird). I’m curious about which apps didn’t work for you.
