For anyone curious, this is actually a very big deal.

Fuchsia is a sort of secret Google project to redesign the operating system from scratch - with a focus of making multi-device interactions a base primative.

The goal is to make multi-device interactions easier and not dependent on pseudo HTTP initiated sockets/streams.

It’s very exciting and hopefully makes it possible to have all the devices you are working with easily work together. For example, pull up content on your phone, pass it to your TV, interact with it on your keyboard, sync with your smart watch, etc.

The opposite today would be depending on a series of memory issues or depending on browsers or socket/protocols to manage a series of interactions between devices.

It sounds like you just described the Apple ecosystem, and I don't mean that's a bad thing to have more than one reimagining of such.

Apple didn’t rewrite their OS to get there, however. I guess someone at Google needs a promotion.

Apple startet with this approach long ago. There was no "modern" approach to solve the problem. However today there is more knowledge to tackle this.

Could you link to a source for that? I don't recall it being mentioned or shown in the video, and it's also not mentioned as core concept in their docs [1].

It's not obvious to me why baking-in network connectivity to the OS would be helpful, but Plan 9 thought so too!

I'm just an amateur plan9 user, but one thing it does is allow the application to be written as if it were just a local application. But because everything is just a file, you can have the application use remote resources just by changing what that file "points to" (the namespace of the application) without changing the application itself.

OS IPC is nothing new, that is how COM works, and Project Treble has added a Fuchsia like layer to Android.

By the way, it isn't that secret, because not only you can track the development on the open, there is at least one device shipping Fuchsia in production.

This is unbelievably cool.

It feels a bit like diving into a new fantasy book or TV series; there's so much to explore. Everything's just so radically different from the world you're used to, and every new fact you learn hints at dozens of other systems you don't yet know anything about. Really a fascinating introduction.

Right? I'm excited about this the way I was when Plan 9 first came out. It's always fun to get in deep to the details and learn something new, particularly when they've reimagined something like Unix. Google is hiring evangelists and have released it to their Nest Hub, so they must be close to wider use. Wondering if we'll see this on the Pixel 6.

Thanks!

Oh my. Is THAT how you pronounce it? How did it manage to get that far from poor old Fuchs? Did it come into english through french? Are you that scared of accidentally cursing?

I am flabbergasted, and fantastically curious! It surely explains why people have been smiling a bit when I have talked about it.

I was never able to spell Fuchsia until I learned about Mr Fuchs.

EDIT: hah, something like that: "named...by French botanist...from the Latinized name of German botanist"

The Android userspace meant you didn't have to publish parts of your rom, now thanks to fuchsia you can keep the whole thing close. We can only hope Google's incompetence kills it.

To answer the obligatory question "but does it run linux?": well, kinda ... it can run ELF binaries, but it only supports the syscalls defined in "posix-lite".

There's also ongoing development on "starnix" which aims to run unmodified Linux binaries.

how is this different to zircon

They discuss it around 30 mins into the video

Zircon is the kernel, Fuchsia is the OS.
