  1. Are you are that there is a Trollope group on yahoogroups?

    As long as it isn't filled with Trollops booted from CraigsLiost.

    You meant to say reentrant.

    NONONONO. You are stuck in single-user/system thinking which
    is never going to be equivalent to single-task/system.
    Wrong. Actually, that is so wrong it's not even wrong.

    think about email and networking. There shouldn't be 500
    copied of that software running if there are 500 emails.

    that has always been the goal. However, when you have something
    catastrophic happening, the sane thing to do is stop the whole
    system before something really, really bad happens to the bits
    on the disk.
    Getting rid of small computer thinking would be a beginning.

    Sigh! Now consider that the core containing the OS has a cosmic ray
    hit it.

    He's reinventing what didn't work well at all. Furthermore,
    it is extremely insecure to insist the computer system have
    a single-point failure which includes the entire running
    monitor.

  8. My PeeCee won't boot from CraigsList.

    Please what am I doing wrong?

  9. How about a class action suit against Microsoft for fraudulently selling a
    product unsuitable for the use advertised and trying to cover their
    posteriors with an unconscionable contract (the EULA).

    I don't understand the law sufficiently to know why this isn't feasible; for
    surely if it were feasible someone would have tried by now.

    That's because VMS wasn't written i C, or you'd have had more than a few
    buffer overruns.

  12. VMS has this facility called 'install', that allowed an application to be
    configured to run with privileges elevated beyond the users own privileges.

    Early versions of the DEBUG utility didn't bother to reduce the privileges,
    so debugging an application which was installed with change mode to KERNEL
    privileges would allow anyone complete access to the operating system and
    hardware.

    So, not even VMS was immune to "exploits to take over the system".

  13. Not only _that_ but made it possible for word processing documents to
    spread viruses. Truly Brilliant, giving Word macros the ability to do
    low level IO.

    IFF the monitor is well designed and written. If MS develops it the
    corruption will be coming from the monitor.

    Let's try this another way. Each user program sees file IO and
    usually has some kind of terminal IO.

    Inside the OS there are usually a switcher, a scheduler, a process
    manager, a file manager, an IO manager, and other basic parts.
    Optional parts relate to hardware configuration and possibly dynamic
    hardware configuration and temporary file systems.

    Now how do UUOs and CALLIs relate to how the above mentioned
    interfaces? (If at all)

    While i can love someone 24/7/365 i cannot have sex to the same
    extent. How do you accomplish this feat? Nor do i have sex with each
    person i love.

    Not really. The proportions of speed seem to remain the same.
    First of all, the virtual OSes will merely be apps and be treated
    that way. Why in the world would you equate 4 threads/core?
    You need to think some more. If the single-point failure is
    the monitor, you have no security at all.
    It isn't going to be tiny. YOu are now thinking about size of the
    code. YOu have to include its data base and interrupt system.
    The scheduler and memory handler alone will by huge to handle I/O.

    That doesn't matter at all if the monitor is responsible for the
    world power grid.


    That is a very bad assumption. You need soft failovers.
    Hardware can't take water nor falling into a fault caused
    by an earthquake or a bomb or an United Nations quanantine
    [can't think of the word where a nation or group are
    declared undesirable].
    HOney, you still need an OS to deal with the virtuals. Virtuals are
    applications.

    I know. I be one of them.
    Yes because all of that knowledge has been forgotten. These days
    people think in single-user/owner terms.
    You have some too. :)

    Because it's the folklore to not do this. I already wrote about
    this a couple days ago. It's easy for me to see why this stuff
    happened (or doesn't happen). I don't understand why others here
    don't seem to be able to see it.
