Ask AtheOS Creator Kurt Skauen About His Creature 278

Posted by timothy from the no-x-no-worries dept.
Developer Kurt Skauen, programming for fun, ended up answering the frequent cries to write a graphical Free OS not tied to the X Window system by doing just that. His AtheOS has been mentioned here a few times before -- it's a Free (as in GPL) Operating System for Intel-and-compatible CPUs with an integrated GUI, a tendency toward POSIX, and more than a hint of BeOS. There are quite a few sites with more information about AtheOS, but you may have trouble just getting past the beautiful screenshots and nearly as beautiful AtheOS FAQ. (There are also ASCII parrots.) Ask Kurt about the past, present, and future of AtheOS here (ask as many questions as you'd like, but please only one per post) and we'll forward the best ones to Kurt for his answers.
This discussion has been archived. No new comments can be posted.

        I'd love to see that. A nice, tight Gaming OS that's Windows compatable with full DirectX emulation would be friggin' awsome. Probably never happen, unluckly - that's A LOT of bloody work to do to get even enough Windows compatibility to run games. (And, well - I was involved in a project to do something like that once. Long ago... the project in question (Freedows) appears to be dead and gone now...) None of the projects that have set out to do something like that have flopped so far. Doesn't mean it's IMPOSSIBLE, just damned hard.


        But if it ever happened - I'd have me an MS free game machine built very quickly :-) (And no, a Linux box doesn't count as an MS free game machine - most of the games I want to play don't have Linux versions :-/ )


      • A directX emulation layer would be very useful not just for gaming, but for a variety of real-time sound synthesis [propellerheads.se] applications. Software synths frequently use DirectX to get a low-latency connection with the audio card, so that you can make realtime changes without a lot of lag between the time you twist a knob, and hear the results.

        Besides, not needing windows to run Reason would truly rule!

    • Mod this guy up, because this was my question as well.

      Of course, it's possible that WINE, Win4Lin or one of the others will port or compile fairly easily under AtheOS.

  • You mention the GPL is free, and AtheOS is GPL'd, and while I will forego a rant about nonfree GPL and such, it is important to mention that Kurt (the Theo deRaadt of the GPL world) has often threatened to make AtheOS closed source, and keeps full control over the entire OS (where possible).

      Why would one do this, we have Linux and BSD to run X Apps very well.
      I like the attempt of AtheOS, where "one" Person controls the direction where the gui is going. This probably keeps the Userinterface more consitent that X is.

      Dont get me wrong, X is fine, but quite oversized and to "flexible" for the masses...
    • I don't know how hard that would be. The BeOS and AtheOS APIs have a lot in common, and there is a BeOS X server. Plus, AtheOS has some networking features that BeOS doesn't, and porting Wine and X to AtheOS would probably be quite easy.
      • I think any such emulation should be done by making an Xlib emulator so that the applications, as much as possible, cooperate with native Atheos applications. It would be best if many X things, in particular window managers, were not supported.

        Unfortunately it appears this is difficult or people are not interested. Most "emulate X" schemes I have seen require an entire X server to be emulated. This either takes over the screen, or puts a screen in a native window, or at best actually mixes the X windows with the native windows but they interact in strange ways. I think this is the wrong approach.

    So have you considered limiting the scope of AtheOS (possibly severely), and aiming at doing a relatively few things exceptionally well? Here I'm thinking of BeOS, which was usually promoted as a "multimedia OS." It seems to me that this might be a way for alternative OSes now and in the future to stake out some territory: do a few things very very effectively rather than trying to be all things to all people.

    • I agree that it would be far more useful to make the "official" Atheos interface much more low level, on the "create a window this shape, draw these rectangles and colors, tell me where the mouse clicked" interface, and put all the work into a powerful graphics engine (which X and Windows lack).

      Writing buttons is pretty trivial (I have done it!), the reason toolkits on X is so hard is the enormous amount of work needed to do things that should be easy, like select fonts and draw them and draw images.

      I also feel that putting the toolkit into the system will lock the design into something that would quickly become obsolete. X, for all it's problems, is still used today, and able to emulate stuff invented 15 years later. Do you think X would be anything other than a joke if it required all programs to use the Athena toolkit?

      However, I cannot prove from the documentation whether or not Atheos is designed this way, but I don't really like what I see. But his toolkit may just be an example, he certainly would need to write a toolkit layer so that there could be anything other than trivial demo programs, and perhaps he intends to allow that layer to be replaced.

    Have you ever considered promoting AtheOS as an OS for GUI-based embedded devices? The competition in that arena now is Windows CE, Palm OS, and Linux - but an OO based GUI built into the OS may be beneficial in terms of performance.

    With Linux, a device developer has to get the core Linux kernel working and then build a GUI on top of it (XFree86 or a smaller X server). Palm OS doesn't have multitasking and isn't very scalable to powerful devices. Windows CE requires a royalty. AtheOS could provide a powerful operating system for embedded devices for free.

    • this depends on how resource hungry and Divice drivers are done

      GUI has to be faily light weight and done in software only as hardware bliting is still a novelty

      the link loader also would have to be tweaked for a differant arch (e.g. gnumach can not run on mips because of the linker and loader at presant (nor can apple darwin only ppc and intel))

      keep in mind that in terms of microprocessors out there intel is very small

      PPC sells more than intel and MIPS may be 10-20 times as much with ARM arch well ahead of these (do you have a cell phone ?)

      my advice to kurt is target it generically and try and build it for MIPS ARM and PPC as well as intel and this will make it very easy to add any others that you want to

    (As I'm sure you know) one of the problems with C++ is that modifying a class changes the binary structure of an object. This then breaks any programs that were dynamically linked against this. This problem has been addressed in several ways (CORBA, COM, staticly linking in the code, or keeping 800 copies of MFC40.dll on your machine, etc, etc)

    This seems (to me, at least) the biggest problem with writing an OS in C++. How does AtheOS deal with this problem?

    Two questions, actually:
    • I think that not having X on board is a good idea, actually, because if you had X on AtheOS, everybody would start porting over X applications and then you'd have a lot of applications with an entirely different look & feel, which would spoil the integration that AtheOS currently offers. However, for the future, there's going to be need for a well-documented application framework in order to facilitate application development (for options such as component development and so on); since you already ported part of Qt to the native AtheOS system, what would you think about porting as much of KDE over to AtheOS as possible without including X, so that not too much of the native system's advantages would be lost, yet you could use the portability of KDE to ensure a broad supply of end-user applications?
    • I realize that you do very much of the actual development yourself, at the moment. What would you think of partially delegating development, such as putting up a list of "what is needed" to-do's, discussing the actual implementation with some developers, but letting them do more of the actual work? Because you've come really far with the OS, but I presume it's at a critical point at the moment where it needs to gain momentum. You could assume some sort of "benevolent dictatorship", we have at least one case in operating system development history where it worked out fine :-)
  • Do you consider AtheOS to be born as a curiousity? Or do you consider Linux, BSD, and other growing OSs to be flawed in some fundemental way that only a fresh start could fix? If the latter, what are the biggest strikes against these OSs and how do you plan to overcome them? And what do you think other *nix need to do to match your goals?
  • Out of curiosity, anyone know what program he used to generate that webpage?
  • Would you consider AtheOS a portable OS? I mean, with BeOS, it ran on at least three platforms, not including BeIA, and they said it was because 90% of the code was platform-independent. What is your opinion of porting AtheOS to other platforms, such as the PPC, some Amiga-esque hardware :-), the PlayStation 2 or whatever?
  • Is anybody working on a JRE for AtheOS? Although Java has hardly taken over the desktop (*cough*), there are quite a few useful apps [freshmeat.net].

    Kaffe [kaffe.org] seems to have been ported [transvirtual.com] to a huge number of platforms, so it may not be too hard to do an AtheOS port as well. The Kaffe homepage has some instructions [kaffe.org] for people who want to do a new port.
