Jack Ryan doesn’t figure out Marko Ramius is wanting to defect. (Hunt for Red October)

My first thought was to start work on a de-replicator. Lot of people about to have a lot of junk in their house and it’ll pile up quickly.

Not sure how long it’ll take until the earth becomes a black hole.

I might also try and put a few new squares on the periodic table.

Edit; now I went back and reread the question, I saw opens source. I will leave the comment as it could be a turnkey solution and stepping stone option to going full open source.

Something like a server on a raspberry pi could be what your after, but I don’t have specific software recommendations for it.

I’ve just started dabbling, so don’t consider this an expert, but a suggestion.

Synology nas’s have a focus on data sovereignty . They have Android apps that communicate from your phone to the Nas for media.

They can also be setup as a private cloud drive initially accessible by VPN to access and a email / web interface as well as instant messager and webdrive

I gave some though to setting up a small private ‘corporate’ style server where people could access . There’s no subscription fees after the initial hardware purchase as your self hosting.

Hypothetically. I’d see if I could take someone and bring them into a Truman show world without them knowing.

Probably ‘Australia Zoo’, Queensland. Steve Irwin is Robert’s dad and was known as ‘The Crocodile Hunter’ .

Not the first time Robert has been in the enclosure. Steve copped a bit of heat from the press after he went in one day with an infant Bob.
