I'm pretty impressed that 37 people are capable of writing an entire OS with a gui in under a year. Looks really cool.

Operating systems aren't that big, and if you know your stuff, I'm sure it's not too hard to pull off. Here's an example I borrowed from StackExchange:

According to cloc run against 3.13, Linux is about 12 million lines of code. 7 million LOC in drivers/, 2 million LOC in arch/, and only 139 thousand LOC in kernel/. (http://unix.stackexchange.com/a/223753)

Edit: Would be nice to have the numbers for the latest Minix release for comparison. Does anybody know how big their core team is? (The kernel is something like 15k LOC IIRC.)

Earlier quoted context omitted.

If no one knows about your project it's name doesn't matter. Bring to mind the old MikeRoweSoft vs. Microsoft thing.

When choosing a name you can't exactly predict future people using your name.

Yeah, but if you are unknown you can easily rebrand

Great news! Now it's worth to learn Rust just to keep up with this project.

Does Redox run in qemu only or also in VirtualBox? I tried it with all devices (USB, Network, etc.) disabled. Installation from ISO to /dev/sda worked fine but after reboot I got a hangup: "IDE Primary Master: Unknown Filesystem". Do I have to format the hardisk image with ZFS before installation?

Btw, if anyone is interested in learning how to write an OS, and interested in Rust, check out https://intermezzos.github.io/. It's a "learning OS" in Rust, with a companion book. Incomplete, but a good start.

Warning: I have no idea about systems programming.

I understand that the amount of lines of driver code comes from the variety of devices. But still, it looks completely unbalanced, when compared to the kernel code itself. So I have some questions here:

1) Shouldn't there be common interfaces / abstractions for most of the devices? 2) If they exist, could they be improved somehow? 3) A bit unrelated, but how fun / interesting is it to develop driver code?
