Haven’t tested it against meta glasses. Essentially it requires the MAC address of the device and pings the shit out of it. May or may not work against the glasses.

Requires Linux. But a raspberry pi should do the trick.

I was fortunate. I was offered a research position from an EU country so it comes with a work visa.

I am one of the US scientists who is moving to the EU due to the US’s anti science policies. I, of course, cannot speak for all US scientists, but China is an unlikely draw for most of the scientists I know. While the US is descending into fascism, China is already there. I’m not sure how many people I know are eager to live in that type of system in exchange for funding. I know a few who are heading to the EU and Canada. Those who are in dire straights due to funding issues are switching to industry positions or changing fields altogether. People from China or Hong Kong who are in research positions in the US, I would expect are more likely to go to China though.
