That chirping sound you're hearing is crickets. Sun, 11 Jun 2006 01:19:00 GMT donotreply@osnews.com (blixel) Comments http://osnews.com/thread?132416 http://osnews.com/thread?132416 I'd never heard of this OS before. It supports SMP and quite a few architectures already. The kernel seems to be *really* well-written - some of the best code I've seen. Everything split up into architecture-dependent and generic code, with most code being generic.

If the developers carry on working on it (userspace, particularly), it could turn into something superb.Edited 2006-06-11 02:14 Sun, 11 Jun 2006 02:01:00 GMT donotreply@osnews.com (nick8325) Comments http://osnews.com/thread?132420 http://osnews.com/thread?132420 Is the documentation page. I don't know that much about OS design. But since it has been divided into sections, I can read through the documentation and looking at key words, I can do some further study.

Thanks HelenOS people.Edited 2006-06-11 02:18 Sun, 11 Jun 2006 02:17:00 GMT donotreply@osnews.com (John Blink) Comments http://osnews.com/thread?132424 http://osnews.com/thread?132424 It looks good, but I'd like to see some userspace work Sun, 11 Jun 2006 02:55:00 GMT donotreply@osnews.com (Rowan Lewis) Comments http://osnews.com/thread?132439 http://osnews.com/thread?132439 That chirping sound you're hearing is crickets.

I don't like trolling, so I'm ashamed to admit that made me laugh and I modded it up for wit value.

You're just lucky I have no idea what the hell HelenOS is, or I might be offended.

But as this is a OS-centtric website shouldn't we be a little supportive when a new OS is released?

Sure HelenOS might look tidier and organized on the surface - but is boring, offers much much less functionallity based on the design/implementation it has.

Well, the kernel seems to be fairly complete, even having the beginnings of capability-as-key security (though not, as far as I can see, applied to IPC). If the user-space functionality was there, it wouldn't be at version 0.2

And having clean and well-organised source code is useful IMO, as it makes it easier to change things later.

The education in eastern europe is also to a very high standard, so we can expect this to be something great.

The fact that my post about this not being an offensive post is the twelfth post in twelve hours almost proves that this post isn't meant to offend. This non-offensive post illustrates that HelenOS, as worthy as it may be, isn't going to get the hot-fire that even AmigaOS, etc. get around here. Now, had he said something about how God-awful HelenOS was and called the devs a raving pack of idiots, that's where I'd start modding down. So, Blixel, here's to you. Had you posted this about Vista, you'd be at +5. Of course, I would have modded you down for "easy target", but you'd have gained it back in spades.

+1 to you! Sun, 11 Jun 2006 21:22:00 GMT donotreply@osnews.com (diskinetic) Comments http://osnews.com/thread?132568 http://osnews.com/thread?132568 Hot-fire and AmigaOS in the same sentence?

On my Dual Xeon box, I get to the kconsole prompt, but nothing I type shows up, so it looks like it's not accepting any keyboard input from it. In vmware 4.5, it hangs either right after saying "This is init" or right after the PCI scan. Mon, 12 Jun 2006 00:35:00 GMT donotreply@osnews.com (adamk) Comments http://osnews.com/thread?132590 http://osnews.com/thread?132590 After iso image is booting (helenos-0.2.0-ia32.iso 2.0M) it start a tetris like game. Mon, 12 Jun 2006 01:22:00 GMT donotreply@osnews.com (fffffh) Comments http://osnews.com/thread?132618 http://osnews.com/thread?132618 It looks like the console process gives each process that prints things its own virtual console. Whatever process prints something first will end up with the first console, and so that's what will appear on the screen.

Poking around in the console process source, it looks like the F-keys display different consoles. F1-F5 on mine show different programs running. So try pressing those

By the way, there doesn't seem to be a lot of user mode code yet (console, framebuffer, keyboard and that's about it) so all you can do is play the little tetris game but the kernel seems to do all the needed things, so I expect it to look more impressive by the next version. Mon, 12 Jun 2006 11:05:00 GMT donotreply@osnews.com (nick8325) Comments http://osnews.com/thread?132619 http://osnews.com/thread?132619 Not a joke - the kernel appears to be fairly complete, but not the user mode code. The tetris game must just be there to test it

But actually, the keyboard and screen drivers and tetris game are all in separate processes. So the tetris game working shows that multitasking is working and the kernel is working properly. (I think it just needs a few driver processes to be more useful.)

One of them is related to the userspace console driver initialization as described on our errata page. We would be interested in you testing the current verision on your Dual Xeon box (and also in your rather old version of vmware):

Do you think you can give it another shot?
If yes, please let us know through our mailing list.

Thanks.

Never mind... Mon, 12 Jun 2006 12:18:00 GMT donotreply@osnews.com (nick8325) Comments http://osnews.com/thread?132636 http://osnews.com/thread?132636 Jakub,

I tried the new UP version in vmware and it worked. In fact, it's clear that it worked previously. Apparently the first console just shows "This is init", correct? The second shows the PCI configuration on the machine, etc?

I'll try the SMP version when I get a chance. I have two SMP machines at my disposal (the dual xeon and a dual P3). I'll give it a shot on both and report back on the mailing list.

What you describe is the current userspace functionality except that the console binding is done on demand. Unfortunatelly, things that do most of the work are not visible (kernel and the userspace device drivers). We addded tetris and libpci so that people can see that HelenOS is kind of compatible with the rest of the world and actually does something. Note that you can switch back to the kernel console by pressing F12 and investigate the system a bit. Looking forward to hearing from you on the mailing list.
