VitruvianOS – Desktop Linux Inspired by the BeOS

VitruvianOS

Vitruvian is the human-centric Operating System.

25 years ago, I configured GNOME to run a BeOS-like tabbed window manager. On a sun workstation.

But that's not what this is. Or not only:

Nexus Kernel Bridge

Nexus is Vitruvian's custom Linux kernel subsystem that brings BeOS-style node monitoring, device tracking, and messaging to Linux — making it possible to run Haiku applications on a standard Linux kernel.

It claims to run apps from Haiku, the current open-source implementation of a modern BeOS.

If you like BeOS, take a look at Haiku https://www.haiku-os.org/ , it's very nice and very usable system based directly on BeOS.
Haiku Project

Haiku is an open-source operating system that specifically targets personal computing. Inspired by BeOS, Haiku is fast and easy to learn but very powerful.

And much better option, running the real deal, instead of some compatibility layer.
Presumably there's a lot more modern software written for Linux which you'd end up running through a compatibility layer from Haiku? The better option seems relative. I could be misremembering how Linux programmes are handled on Haiku though.

Maybe the fallacy is not exploring what a given OS is great at?

We don't need to clone UNIX all over the place.

How strictly do you mean “UNIX clone”? Because Linux isn’t strictly UNIX. But then at the other end of the scale, BeOS was also partially POSIX compliant and shipped with Bash plenty of UNIX CLI tools.

Perhaps it’s better to play it safe and just run DOS instead ;)

I've been a fan of Beos philosophy since the Personal Edition but never had the occasion to run it on steel as I was too poor to have two machines back in the days, and now I miss login/password prompt at boot on Haiku. But i'm following it closely and I hope i'll be able to install it on my X220 for a web/mail machine !

You didn’t need two machines to run BeOS. I ran very smoothly on a Windows PC via dual booting.

BeOS 5 could even be installed on a Windows FAT32 partition alongside Windows (it created a 50MB virtual disk).

At one point in time I had Windows 95, Windows 2000, Linux (possibly Slackware) and BeOS 5 all running on the same single PC.

The important question becomes can you stack the window decoration "tabs" of different apps into a single stack of tabs like in BeOS?

Demonstrated here (animated):

This is what we needed in our OSes instead of Firefox tabs.
I hope it’s not just the look. The ability to group tabs from various apps into a single window was the best UX feature it had, and I still miss it sometimes.

I bought an Amiga in the early 90's and enjoyed it immensely. Commodore went under and Amiga died.

I bought BeOS in the late 90's and enjoyed it immensely like a breath of fresh air in a sewage pipe. BeOS died.

With my track record I really, really should've bought Windows. Twice, to make sure.
