I did search the D news groups and found no previous reference to SANOS.

How about translating this in D ?

~~~~~~ SANOS: http://www.jbox.dk/sanos/

Sanos is a minimalistic 32-bit x86 OS kernel, written 98% C and 2%assembler,
running on standard PC hardware.
This enables you to run java server applications without the
need to install a traditional host operating system like
Windows or Linux.

The kernel was developed as part of an experiment on investigating the
feasibility of running java server applications without a
traditional operating system only using a simple kernel.

The kernel implements basic operating system services like booting, memory management, thread scheduling, local and remote file systems, TCP/IP networking and DLL loading and linking. A win32 layer allows the Windows version of the standard HotSpot JVM to run under sanos, essentially providing a JavaOS platform for server applications. This enables you to run java based server applications, like tomcat and jboss, under sanos.

Alternatively, you can use sanos as a small kernel for embedded server applications written in C. Sanos has a fairly standard POSIX based API and an ANSI Standard C library. In this case you don't need the JVM and the win32 wrappers.

Sanos is open source under a BSD style license. Please see the COPYING file for details.

Hello,
very curious: the fact is that I was just at this moment looking for an OS to
port in D because I'm thinking of doing something like that since a while and I
just came up there to post a message about the same thing (well not proposing
this SANOS).
I looked up SANOS and it seems to be good.

I'm very interested in that kind of thing, I do not have very much time but I have a little bit which can be enough.

I always thought that porting an open-source OS would be better than creating one from scratch because we would have driver compability and all, you know.

Moreover, I love BSD license ;)

I'm really interested, as I said.

What about you? Other people interested?

We will have to speak of details about the OS and all.

Hytak.

there's a project on DSource which aims to create an entirely new OS using D as the main language (http://www.dsource.org/forums/viewforum.php?f=73). There's some interresting discussion in the forum.

I really don't want to seem like a naysayer, but just converting an existing OS to D does not hold my interest. Converting code is something I really dispise. At no time do I feel more useless than when I'm converting code from one language to another, with the intent to make it do the exact same thing. It's fine (and very necessary sometimes) for small portions of code, but converting an entire OS to a new language (IMO) seems impractical.  Aside from my personal disinterest, direct conversion would not give you the chance to design a new abstraction that takes advantage of a lot of the neat features in D. 

This is just my opinion, but I don't think Trevor (the guy doing the OS on dsource) has the right idea either. To me, a minimal kernel written in D (and asm) from the beginning would be much more interresting because you could use an OO design. It would be great to learn the internals of an OS, and to show how they interact with each other. In addition to that, it might be a useful framework for creating single-purpose OS' (i.e. Ghost (sys restore) or Partition Magic). We might start seeing other (open source) tools with powerful and user-friendly capabilities.

I would love to hear more about your ideas - and would like to assure you that my mind has yet to be set in stone on any particular direction - so you input would be very influential. Start a topic on the forum or email me...

In other news - I have been incapacitatingly busy... I finnaly got a chance to breathe - and than I couldn't breathe cause I got a head cold. Now I am healthy and I have some free time, hopefully I can get some cool stuff done on Terra and Titan.

Thanks,

I have to admit that Chris is right about the
it's-boring-to-only-port-code-lines. We could, however, use another OS a base
and modify it... although I'm not sure it give us a lot of possibility.
Anyway, I only think that it would be good to port an OS for the driver thing. I
know that Trevor's project would assure a compatibility with different portion
of the OS, but would it give driver compatibility too?
The fact is, there is many people interested in OS development in D and it would
be good that all of them decide to discuss at the same place.

While ye sleep - I make magic happen.. OK, it's not magic.. But here is a start...

If you want to join in on designing the Titan kernel with us... (me so far) than come and visit, register, post, etc..

I registered!! Even though I have zero knowledge about kernels, but:

Hm. Sorry, guys, DOS already exist. It was written long before D? Oh, okay... ;)

Just want to ask you not to fall into the POSIX swamp. Build an object oriented OS, as D's paradigm is OOP. Look at BeOS, look at WinNT, but please, please don't use POSIX or Unix as the foundation. POSIX is old and hopefully dying.

Good point, I second that!
I'm sick of unix/linux, actually I have a prejudice against linux.

I agree too, moreover, I heard good comments about BeOS although I never tried it.
