More like [ˈd̪ät̪ä], no long vowel.
That’s my B, I was looking at Ecclesiastical Latin for that one :3
Interesting points though, thanks for the elaboration. Shows the layers of silliness that is depending upon other languages for the way we pronounce words.
Your science teacher was wrong, unfortunately. In Classical Latin, datum is pronounced as [ˈd̪ät̪ʊ̃ˑ] “dah-too(m)” and likewise data as [ˈd̪äːt̪ä] [ˈd̪ät̪ä] “dah-tah.”
Not that Latin should really have a say in how we speak English anyhow.
Take the red pill, all linguistic categories are equally unreal.
I use CachyOS and it works great for my gaming needs. I use a PS4 controller on it just fine, no clue about the newer XBOX controllers, but I don’t see why they wouldn’t.
