3/5     According to the solaris sysadmin guide I need to be in single user
        mode to do a dump/restore.  I've tried dumping when I'm not in single
        user mode and it works fine.  Should I be afraid that anything bad
        might happen?  Anybody had any bad experiences with ufsdump in user
        mode?  Thanks.
        \_ It'll complain sometimes if a file changes while it's backing it
           up, but it basically works fine.  -tom
           \_ referential integrity cannot be assured if dump is performed
              in multiuser mode.
        \_ Do you care about data integrity? If you do, then you should be
           in single user mode, since you can better control the accesses
           to the filesystem.
           That said, if you are doing this at home on your personal box,
           with one user and maybe the web/ftp server running, its not a
           big deal.
        \_ just curious, can you force remount the filesystem into read-only
           mode, then dump it, then remount it rw?  Might solve the integrity
           issues, and only lose you last-access-time information.  -ERic

2/5     I like Adobe Flash. When written correctly, it scales along
        with your browser size. It looks consistent on every single
        browser. It is predictable. On the other hand, I'm not a big
        fan of CSS/HTML, which for the most part, look wildly different
        between browsers, and don't even work consistently or
        correctly at times. So why do so many people (like Steve Jobs)

        legacy Sun hardware that no one uses anymore, its fading workstation

11/29   I'm experimenting with virtualization, and as a poor college student
        I'm wondering what the best alternatives for virtualization are, and
        how best to cut my teeth on messing with non-linux platforms (or I
        guess interesting stuff on Linux would work too). Right now I've got
        FreeBSD7 running on KVM on my home computer (on a Core 2 Quad), and am
        somewhat at a loss as to how to use it. (More details: bridged

9/24    Why is nscd going crazy?  DoS?
        \- back in the solaris say 2.5-2.6 era, it had both some bugs
           (some malformed nis maps made it go crazy) and architectural
           flaws in the IPC/door+threading mechanism. if you are running
           OS-recent, dunno, but you can trace it.

3/30    Question: I just deleted 60 GB of files from an 80 GB disk. The
        disk activity lights were blinking like crazy and I could hear the
        drive crunch while the data was deleted. This is under Solaris.
        Anyway, I think UNIX uses unlink() when files are deleted. Shouldn't
        it just update the free list on the superblock and call it a day?
        What is all the crunching about?

        what I can do about this?  (Or a better solution?) -jrleek
