Impressive. Always nice to see more interoperability.

Also, I fail to see how second link has anything to do with Bluesky federation.
Oh, I see, that specific reply is from Bridgyfed.

Yes, this is something that should be taken into account when designing this software.
Set dual-boot as a default / design UI in a way that offers dual-boot as a preferred option.
And many other technical issues will probably appear that will have to be figured out.
But I think that at least even thinking about this is a good start.
Also, this reminds me of 2013, when people accidentally nuked their Windows installs with Linux because they wanted to get the Tux in Team Fortress 2 (Valve gave it to people who played Linux version of TF2).

Oh, this video by Digital Foundry is also relevant:

I'm sure that there are games (either video games or IRL physical games) designed for this. Some simple "here are some possible instructions, use them to achieve some goal" thing.
Something like described here:
https://wiredme.com/blog/active-coding-games-for-kids/
But I am interested in knowing more examples of such games. Is there any Wikipedia article for this category of games? Is there any list with more of them described?

Is the "Projects" section of https://the-federation.info/ what you are looking for?

Don't know, but other three Invidious instances listed on https://redirect.invidious.io/watch?v=CBCujAQtdfQ seem to work.

there was this satirical "web browsing simulator 2025" or something like that where you had to do all those things.
but I don't remember the exact name and can't find it with a search engine. Maybe someone else knows what I am talking about.

Did you check out NewPipe?

I was not aware of the issue that downvotes negatively affect mental health.

Isn't that exactly the beauty of the fediverse?

There are / were some bridge bots that mirrored the posts from one site to another. Bur i don't know what the current state of those is.

Thank you very much.

BTW good presentation on FOSDEM👍

Ah yes, sorry. The video is from Youtube, but post points to a link that also adds one of privacy frontends. However Youtube has been very uncooperative with these kinds of things in the last year or so.
Here is a direct link: https://youtube.com/watch?v=4TmHSsIU1ns
I also added it to the post description.

As jet points out, QEMU for actual hardware virtualisation.

There is one relevant thing, which is not exactly in the same category, but does somewhat similar thing:
containers
most popular example being Docker
https://en.wikipedia.org/wiki/Containerization_(computing)
containers don't emulate whole hardware stack like virtual machines do, they just run the guest OS on top of host OS.
so because they don't put resources towards emulating hardware, they are much more resource efficient.
so if your problem is "I'm running Fedora but I want to run something that for some reason runs just on Ubuntu", then you could use containers for that.
containers are mostly used in headless environments (as in servers, no GUI), so running and displaying desktop Linux inside them is a bit tricky, but it can be done.

I'm not the author, but posting it here because it is amazing project that deserves exposure.

indirectly forces you to buy wireless earphones

USB-C wired headphones exist

edit: lol, replied too quickly. You mention wired headphones in the next sentence.

I think that the insistance on headphone jack has gone too far.
There are now enough wired USB-C headphones and wireless earbuds available.
Yes, there are edge cases, like people who work in audio industry where most equipment uses jack as standard connector, or car aux ports, etc.
But when it comes to most casual listening, there are enough solutions.

When migrating to the new phone I tried with USB-C to 3.5 adapter. It did not work most of the time. I suspect that the issue was in my somewhat defective headphones, which have damaged wire and therefore unreliable connection.
Previous phone and other devices were probably able to mitigate the occasional "disconnect", while the adapter completely dropped connection.

But then I bought USB-C headphones, which work fine.
