Thu, 11 Jun 2009 23:47:00 GMT donotreply@osnews.com (ShadesFox) Comments Comment by merkoth http://osnews.com/thread?368067 http://osnews.com/thread?368067 Nice! Great times for us OS enthusiasts. Lately, quite a few projects have arisen, some of them with very innovative ideas. It's nice to see so much activity in a sector clearly dominated by giants with a lot of history (Windows, and the various flavors of UNIX including MacOS).

I could have been personally interested, but even without the copyright share agreement, GPL3 is a complete show-stopper, and even more so in the embedded sphere.

Especially since there are other L4 variants you can use that are BSD-licensed.

The bigger story here is the number of L4 projects going on.

I still would be somewhat more interested in an L4/NetBSD port. Linux/glibc are just amazingly bloated these days.

I wonder, why people are so keen about repeating the past?

Isn't it much more exciting to design your own programming language, interfaces, environment, and then code your own OS there?

First of all we don't use anything ugly and old. I hate them.

For example we don't have Makefiles. We use SCons (new).

We don't have ugly shell scripts. We use Python.

We don't have ugly x86 assembly, although assembly is in itself hard to read, please take a look at Codezero vectors.S you will see how well documented it is.

Codezero *is* indeed, a candidate for you to design your own environment and OS. The L4 API gives you the least common denominator mechanism to build different systems on top. The POSIX services are just an example.
What's better, is each of them may co-exist and interact on the same system.

The Codezero project started with the very same limitations I see in the existing systems that you have mentioned.

I would definitely like to clone the git tree and look at your implementation more closely.

I praise the idea of having only the minimum of system calls in the kernel. I tried to clone QNX Neutrino kernel long time ago; I think it grew too much already (~64 syscalls).

I am currently developing a completely new programming system (kind of new language + IDE, but not exactly), and I'm looking for some open microkernel implementation that could become a basis for my own kernel (written in this new language). Fri, 12 Jun 2009 13:01:00 GMT donotreply@osnews.com (r_tty) Comments Great work http://osnews.com/thread?368157 http://osnews.com/thread?368157 I just want to say that I think that your contribution to the open source community is awesome.

I hope this isn’t way too off-topic, but I’ve got a UI project in the planning stage that shares similar goals, but it’s more aimed at the desktop. It could be interesting to use the kernel at some point though. If you want to check it out, take a look at http://brevityos.blogspot.com/.

GPL3 is a complete show-stopper, and even more so in the embedded sphere.

Care to explain why? Fri, 12 Jun 2009 16:49:00 GMT donotreply@osnews.com (Sodki) Comments RE[2]: Codezero http://osnews.com/thread?368214 http://osnews.com/thread?368214 Actually I would rather leave this as my personal opinion to which I am hopefully entitled to.

But there is a voice of my employer in there too: we (employees) do not touch (distribute) GPLv3 code no matter what and try to avoid GPLv2 at all costs, regardless of me and my personal opinions.

Then we could port Apple's IOKit or QNX drivers.
