Tangential, but it is so funny to me that “TFA” has become a totally polite and normal way to refer to the linked article on this site. Expanding that acronym would really change the tone!

I'm not sure it is 'totally polite'? I usually read it as having a 'did you even open it' implication that 'OP' or 'the submission' doesn't. Maybe that's just me.

Maybe it isn’t totally polite, but it IMO it reads in this case more like slight correction than “In the fucking article,” which would be pretty aggressive, haha.

I always thought it meant “the featured article”; I must be a lot more wholesome than previously indicated!

Unless they need something Pi specific I don't understand why this would be preferable versus just virtualizing instances on a "big ARM" server. I'm sure those exist.
