What an astounding achievement. In 6 years, this person has written not only a very well-designed microkernel, but a build system, UEFI bootloader, graphical shell, UI framework, and a browser engine.
The story of 10x developers among us is not a myth... if anything, it's understated.
Didn’t expect to see my project on the main page today ‘^^
Right now the build is broken, so you can’t test the full OS, but you can run individual apps with:
Impressive achievements, congrats! You said that your microkernel is "influenced by Zircon". Did you also study other architectures like e.g. sel4, Minix or openQNX? What do you consider the important design choices in your microkernel design? Is there a document where you go into this? Have you done performance measurements, i.e. to which other microkernel design do you think your kernel is comparable in terms of performance?
Thanks! Skift is basically a patchwork of all the OS ideas I like. The UI takes inspiration from SwiftUI/Flutter, the microkernel is influenced by Zircon, and there are some Plan 9 ideas where everything is a URL. A few bits are probably inspired by NT and Darwin too, though I don’t remember exactly which.
Hi monax, I would like to hear how you started the project. I am also currently trying to implement my own micro kernel, with hopes of doing something similar to SkiftOS in order to learn OS fundamentals, but I don't know how to start. What are the first things to tackle when taking on such a project?
I don’t know what I can tell you, I think where you start and how you start don’t really matter. The important thing is to keep going. These kinds of projects are a lot of work, and as long as you keep making progress, you’ll eventually get to what you want.
I always paste this book here when hobby OSes appear. I wrote my own GUI OS in the 90s and I couldn't have done it without this. Copies available on your usual shadow library I would imagine...
What ideas do you employ around security? Do apps have full access to memory? To hardware? Is there a permissions system? Sorry I'm not that familiar with how microkernels work.
Apps don’t get full access to memory or hardware. The kernel only maps what they’re allowed to see. Drivers live in user space, and apps talk to them through capabilities (handles you can pass around). There’s no ambient authority, you only get access if you’ve been given the key.
What about filesystem access rights? Does any application have full access to all user's files? Or only to files belonging to this particular application?
I dove deep into the code base. Found lib-sdl. Found impl-efi. Found co_return and co_await's. Found try's. Found composable classes. Found my codebase to be a mess compared to the elegance that is this. We are not worthy...

Very impressive!

```bash ./skift.sh run --release <app-name> ```
on Linux or macOS.
To see all available apps:
```bash ls ./src/apps ```
```bash ./skift.sh run --release vaev-browser -- <url-or-file> ```
The HTTP stack is super barebones, so it only supports `http://` (no HTTPS). It works with my site, but results may vary elsewhere.
Most of my time so far has gone into the styling and layout engine rather than networking.
As a Norwegian, the name of this system and those components sound Danish (Skift, Karm, Opstart) and Danish-inspired (Hjert). Am I right? :)

and you'd get hired in a ton of places.
I'm curious, how come the app I just compiled works on macOS?
I am amazed that you also managed to write a browser engine!

The modules... :chefs-kiss:
