Gentoo user here. It can be great for dev as you have everything that is required to build the software you're running assuming you're trying to produce something using the same base. Ie C++ with Qt for KDE etc.

It's also a lot easier to build your own repo and packages with than any dev setup I've seen, it's literally just a text file.

It does take a while to compile. However you need opinions to use it.. Otherwise you will just have useflags enabled on everything. It does require a bit of understanding of how linux is built but the guide does most of the work for you, and it's easy to install on an existing system. If you're using btrfs you can install it on a subvolume and try it out easy.

However I used it during the 00s and 20s.. But not the 10s. The difference is that software is moving way too fast for distributions to keep up with, so you will definitely want to build your own ebuilds at some point. Emerge / portage can sometimes cause issues upgrading too. But nothing a btrfs snapshot can't save you from.

Used to use Xnest to do this. IDK how easy it still is these days.

Knoppix got Ubuntu halfway there.

Is it Space Odyssey?

This.

Thanks to Meta BTRFS is apparently got/getting it to a certain extent too: https://youtu.be/6YIc2fVLVPU?si=ngiHWS0fw2zIHf2M

That's very coldwaresq behavior

Most of the reasons mentioned, and also they are a bit out of the way to install and setup, you don't get much feedback as per users using them. As they integrated with the OS you have to search for them as a user, and you have advertise them as a someone packaging. Every extra step creates friction which ads up. It feels like a solution based in the concept of maintaining SEP. -- Plus people aren't exactly paid to do this.

Thanks. I didn't know, it is also on my list.

Microsoft invests a lot of time and effort in (selective) backwards compatibility. It's one of the draws to the OS. In past leaks of code we have seen it's code base is littered with special cases. I can't find the link but here have this almost good enough reddit link: https://www.reddit.com/r/Windows10/comments/lpdn0x/microsoft_really_understands_backward/

I'm contemplating trying to run the meta bridge locally to get around that issue, it has to do with their server running in I think Finland?

Would this mean free news for all residents and citizens and journalist get paid for consumption?

The people that do care the most have a choice to use older cars and that reduces resistance now.
