  1. Re:Opening Up on SourceForge Fails To Forge Source? · · Score: 1
    I don't think there's any question that SF is going to have to make the step and fully open up. If they don't, I think it's quite probable that they will see alot more critical commentary pointed their direction.

    One possible solution for the volunteers to take is to:

    1. Go to SourceForge
    2. Register a SourceForge project
    3. Put the latest code, docs, etc in the CVS repository
    4. Progress forward with the intention of a codebase merge.

    At least this puts them in the position to more easily merge their changes with the ongoing SourceForge development.

    The SourceForge folks might even decide to make use of the CVS repository since they did not have to put forth the effort to set it up. They are after all time-bound right now. Perhaps they just haven't had time. (Giving the benefit of the doubt, of course)

    Regards,

  2. Re:Clustering on Linux Clusters Explained · · Score: 2
    BTW. Any expert out there know how I can start a shell session on my server, log out of my X-terminal without quitting it and be able to check out the progress next time I logon.
    If I understand your question, nohup is your friend.

    I routinely run non-X, non-interactive apps thus:
    nohup prog >output 2>&1 &

    Later when I log in, I
    tail output

    YMMV on C shell.

    Do note that some versions of AIX have a bug in ksh which prevents a proper nohup and you should exec ksh first.

  3. Re:Why reinvent the wheel? on Serial ATA and USB 2 · · Score: 1
    What's SSA? I hadn't heard of this before, and I'm curious to know more.

    SSA is IBM's Serial Storage Architecture . My only experience with them was in conjunction with two multiprocessor J40's. We had two full towers of SSA disks that where linked in with both J40's. Any disk in either array was available to either system. (Don't try to mount the same disk on both machines at the same time!)

    It seemed pretty fast and allowed amazing flexibility on the placement of the external drive towers. The cables, were, of course, expensive.

  4. JFS logging level on IBM releases JFS to GPL · · Score: 2
    JFS : Mostly working, from the sounds of it. The TODO lists logging as incomplete. Nothing on the web pages as to what type of logging is done, but I'm going to guess it's full journalling.

    Gleaned from http://www-4.ibm.com/softw are/developer/library/jfs.html: JFS only logs operations on meta-data, for data consistency consider using syncronous I/O.

    That having been said, JFS is about as bullet-proof of a filesystem as I have ever used. This is a good thing.
