https://www.drawio.com/ could probably work

Seems like all of the communities except https://programming.dev/c/ask_experienced_devs has been federated with thebrainbin.org now. So you can find them here:
https://thebrainbin.org/magazines?query=programming.dev&fields=names&federation=all&adult=show

edit: and now the ask_experienced_devs is also visible in the magazine list, but not populated with posts yet.

In Mbin (the software thebrainbin uses) they aree called magazines

As you said the guess work is mostly already done in Denmark so those services would do the trick.

I wonder how much of a headache it would be for LIRs to ensure no /24 is used in more than one country at the same time.
I imagine their services are already geographically separated for contractual/billing reasons.

I might be a pessimist but it honestly feels like the question isn’t if we’re gonna end up in that totalitarian horror story but rather how quickly it will come to pass.

It wouldn’t be such a bad idea if they were able to remain mindful of the fact that there is no way to tell how old somebody is over the Internet.

yet.

I imagine they will force the large social media sites to require “MitID” (Danish eID) if the visitor IP resolves to Denmark. Meaning only kids who learn how to use a VPN gets to use social media.

edit: Seems they mention the eID in the article:

Officials in Denmark didn’t say how such a ban would be enforced in a world where millions of children have easy access to screens. But Stage noted that Denmark has a national electronic ID system — nearly all Danish citizens over age 13 have such an ID — and plans to set up an age-verification app. Several other EU countries are testing such apps.
“We cannot force the tech giants to use our app, but what we can do is force the tech giants to make proper age verification, and if they don’t, we will be able to enforce through the EU commission and make sure that they will be fined up to 6% of their global income.”

Considering your other solution parts include simcard dongle, maybe look at KDE Connect to send/receive sms on your linux machine?

Yeah, for a budget friendly AI GPU I would look for a 5060 Ti 16GB.

I know my cousin and his friends used hamachi back in the day, if setting up your own vpn network is too much work that might be a solution.
