Announcing Cooperative Linux 321

evilmf writes "Well... I was on my daily "relaxing" read of the LKML when I've found an interesting announce about "Cooperative Linux", in this message from Dan Aloni. It allows you to run Linux on an unmodified Win2000/XP system, just launching another app. Dan says that Cooperative Linux is 'is stable enough (on some common hardware configurations) for running a fully functional KNOPPIX/Debian system on Windows,' and provides some screenshots in the project homepage."

      What?

      The power of this is that it will allow people to try and experience linux without complicated duel-booting or format/installing.

      More and more people started using linux when bootable stand-alone versions were developed. This will support this boost many times over.

      Think about it. Hack kiddies hear that linux is the way to go. They install it over/within windows... and god forbid, actually realize that linux is a great tool. When I was growing up, I had to limp along with my OS-of-the-day box while my dad was protective of his little system. With this system, future linux kiddies and parents can live in harmony.

      If people believe that they can do their daily activities with their linux programs, then a proportion of these will dump the windows portion to get the performance boost.

      This allows users to ease into linux.

      • Heh, like my parents would have let me do that. There was a product called WinLinux that would install on a 9x/ME system, and let you reboot into DOS mode and start it. They wouldn't let me install it because they were afraid it would mess things up. I threatened them with a RedHat 8 CD set I had just burned... didn't work.

          If they won't let you do that... then you have to go old school. You must convince your parents that they need a newer and better system so you can run the Maestro [telascience.org] java simulation to enjoy and learn from the current Mars experience.

      You can already run many, many apps that were written for linux by using Cygwin [cygwin.com]. As long as the program is userspace, it can usually just be compiled for cygwin. This has the advantage of producing a windows binary and is pretty speedy. I've got KDE and all its applications running just great in cygwin on a Windows 2000 platform. They have XFree86 that you can use, but since I already owned a copy of Exceed, I can just use that.

    • Think of it this way:

      Eventually, someone will come up with a kick-ass IDE for developers to write once, run anywhere. A linux application will merely need a DirectLinux layer to run under Windows.

      This is huge for Linux. Now if we could get the desktop situation sorted out, we can start implmenting Linux on the desktop.

      You could almost get away with this using VMware, but now with this Cooperative Linux project, it doesn't matter anymore!

      If this gets the attention that I think it deserves, this could literally shake apart the entire foundation of the folks who continue to decry Linux. Now a savvy admin who wants to use the Linux versions of Windows crapware can do so, without reinstalling the OS and incurring the wrath of the Microsofties. He gets the best of both worlds: high-quality free software running on top of the "sanctioned" OS. The only drawback to this thing, IMO, is that it may stifle the efforts of people who are trying to port some of the more sophisticated Linux apps to Windows, and may simply give up when they hear that because of this, no porting is required. But I doubt that will be a major issue.

      Here's to hoping this project goes somewhere!

        Look at it the other way : if great linux apps are not ported to windows, but instead are delivered with an easy install of colinux+a small distro (the keyword here will be easy !) then more people will learn to know linux. And one day perhaps install it as 2nd OS on their machine, from which the step to primary OS is a small one !
        • You are absolutely correct, of course - if CoLinux is eventually surrounded with a distro dedicated to this sort of thing, it may actually help in legitimzing OSS/Free software in the eyes of the skeptics.
        • I think the easiest setup would be if you could emulate linux apps in a window without having to boot up the whole disto. either way I think it will be more of a good thing for OSS than Linux because most users will think of linux as just a program that allows them to run OSS software.

        ... and the time I typed
        vi `which startx`
        ... only to have vi attempt to open
        C:\SFU\X11R6\bin\startx^M
        ... which, as you might guess, didn't work (it choked both on the C:\ and the ^M).

        Good times, good times. Also it broke cygwin's emacs-style line editing (presumably by changing some terminal-related DLL) and WinCVS (by setting EDITOR=vi systemwide). Fortunately both of these problems went away when I uninstalled it.

    When I wan't to use *nix tools under Windows I've always trusted Cygwin [cygwin.com], but I can see how this project can provide a good alternative to Cygwin XFree86 [cygwin.com] as suggested in the roadmap [colinux.org]. This could also provide an excellent solution for developers to test interoperability between Internet Explorer and Linux webservers - especially if they are limited to one computer. It could also be used to educate people on using Linux, it is a perfect match with Knoppix [knopper.net] in this respect.

    Wine [winehq.com] developers could use this compare apps running natively and those running under wine side-by-side.
    • Cygwin can't run a lot of Linux apps directly. Most of the time they need porting, because libraries are not the same. Both try to be POSIX complaint, but both aren't, so the work is usually fairly minimal, but it's still work to be done. CoLinux allows it to all happen transparently with no source code changes. As such, it's much more useful.

      Windows Services for UNIX also suffers from the same problem, it also tries to be POSIX complaint, but its POSIX defficiencies match neither Linux nor Cygwin.
      • Windows Services for UNIX also suffers from the same problem, it also tries to be POSIX complaint, but its POSIX defficiencies match neither Linux nor Cygwin.

        Erhm, is SFU more or less POSIX compliant than Linux? You make it sound as a POSIX defficiency is a good thing ;-)

    • To run coLinux right now, you still need the Cygwin XFree86 server. All coLinux can do is essentially a text-mode virtual console. This is okay, since running the X server as a native windows app is potentially faster. I frequently use Xnest in Linux as the display for my VMWare machines because it's so much faster. So there's no real need or hurry to get virtual graphics card support for coLinux, in my opinion.
    • Talking about Cygwin, I remember trying to copy a file from Windows to a Linux computer via the network. It was pretty big, and I didn't want to waste time using SSH's encryption. I tried netcat (they have a Windows version), which worked quite neatly, but it was damn slow.

      I had a Linux system (not the target system), where I could smbmount the Windows share, read the file from the SMB share, and netcat it out to the target computer. Fascinatingly, transferring it this way was a lot faster.

    We all know how Windows assumes it is the only OS installed, when dealing with things like disk partitions, MBR's etc. How does the Windows NT kernel like sharing Ring 0 with Linux?

    Overall this is an excellent innovation for Linux to move forward. I suppose you could chart the increase of Linux "market share" as follows.

    1.) Linus and his friends
    2.) Early Distributions
    3.) Redhat makes inroads
    4.) Live CD's (Knoppix et al)
    5.) CoLinux

    You have gone from experimental boxes only, to dual booting to Live CD's to try Linux out (very slow...)

    If this can come close to Linux alone in speed, then this is a major step forward.
    No more lengthy installs with dual booting etc.

      That should be no problem. Vmware already locks partitions or even serial and USB devices for it's own use. Obviously you cannot share these partitions or devides with both operating systems, but one at a time is no problem at all.

      I don't know about really slow. CDROM are definately not _that_ slow anymore. My Dell laptop has no problem at all running knoppix, including sound, firewire, networking, usb support. As long as you have enough memory (256 at least, 512 mb runs great) it is not slow after startup either. And compared with a complete installation of linux it takes a lot less time. Upgrading is easy too :)

    Why this does seem quite cool I want to offer a warning before you go and install this on your non-backed up mission critical server.

    Many projects have attempted to achieve this goal. It's taken quite a bit of time so far. This project has taken a short cut though by simply letting the Windows kernel and Linux kernel run side-by-side in kernel mode. Traditional approaches don't allow this.

    That's because if anything goes wrong in the Windows kernel, you risk trashing your Linux kernel the same applies for the Linux kernel trashing the Windows kernel.

    Before you go and so Linux never crashes or Windows never crashes, what you're relying on is that this particular project has enough of an understanding of both kernels that they can cover every circumstance where there would be a negative interaction.

    I'm not saying this can't work, I'm just saying I'd be very careful about running it on anything I cared about.

This runs the risk of becoming Linux yoked to that model, unless its creators specifically preserve Win 2000 compatability, and given how disappointing 2000 was, what are the chances of that? 2 versions down the road, this will probably only run with Longhorn.
  • It looks just the same as Cygwin. What is/are the differences?
  • This has the *potential* to be a very cool project. Right now it's at 0.51 release status, source only, with no docs. Only a small percentage of users will be able to get it up and running in this form. Once it hits 1.0, or even 0.9 and is stable enough, I'll be more excited.

    Now, I've read almost 200 comments on this thread.. (that's all there is so far).. but has anyone actually seen this operating?

    Call me skeptical, but I just don't see it working well.

    I see the points (good and bad) for it all, but I just don't see it working well.

    That's my question. To me this make Linux look like just another app that you can install on windows, and have fun playing with.
    I think that stuff like this actually sets Linux back, and doesn't move it ahead. Linux is an OS, not an app.
    The real work to be done is to make Linux better than windows, in every way, and make it easy for people to use. Linux doesn't need more apps, it has most of the ones that normal users would need, and DTP and Graphics progs are getting to be on par with windows and mac.
