I decided to dig through open source to examine the state of Google's upcoming Andromeda OS. For anyone unfamiliar, Andromeda seems to be the replacement for both Android and Chrome OS (cue endless debates over the semantics of that, and what it all entails). Fuchsia is the actual name of the operating system, while Magenta is the name of the kernel, or more correctly, the microkernel. Many of the architectural design decisions appear to have unsurprisingly been focused on creating a highly scalable platform.
It goes without saying that Google isn't trying to hide Fuchsia. People have clearly discovered that Google is replacing Android's Linux kernel. Still, I thought it would be interesting for people to get a better sense of what the OS actually is. This article is only intended to be an overview of the basics, as far as I can comment reasonably competently. (I certainly never took an operating systems class!)
What excites me the most about Fuchsia and related projects are the people involved. The pedigree here is astonishing - there are quite a few former Be, Palm, and Apple engineers involved. The linked article contains a good higher-level overview, and I do truly believe it's one of the most exciting projects in the operating systems world right now.
What remains to be seen, however, is this: just how serious is this project? The breadth of the project and the people involved seem to suggest this is indeed something quite serious, and all signs point towards it being a future unification and replacement for both Chrome OS and Android, which is quite exciting indeed.
