Either windows’ or windows’s is correct, actually. The reason is because of exactly words like “Windows”, if you use the former, it sounds like it’s a possessive of more than one window, but it’s a possessive of a proper noun, Windows. The latter is more correct in this case because of that. (it’s also pronounced that way!)

Yup. All of that is true. It also protects you from yourself by preventing you from making changes outside of the home directory so you can’t hose your system accidentally. It’s intentional.

Your M.2 port can probably fit an M.2 to PCIe adapter and you can use a GPU with that - ollama supports AMD GPUs just fine nowadays (well, as well as it can, rocm is still very hit or miss)
