12/31  I am looking for a PC tech/guru as a goto-guy when problems happen,
       (hard disk failures, etc.) must be located in the bay area, rates
       negotiable.  -daveh@csua.berkeley.edu
        \_ Geek squad will also archive your porn for free!
        \_ Shouldn't everyone at a csua address be capable of this?
           \_ I'm guessing he's got a business and doesn't want to spend his
              own time fixing windows.

1/4     I want to test how my servers behave during a disk failure and
        a RAID reconstruction so I want to simulate a hardware failure.
        How can I do this in Linux without having to physically pull
        a drive? These disks are behind a RAID card and run Linux. -ausman
        \_ According to the Linux RAID wiki, you might be able to use mdadm
           to do this with something like the following:

9/13    Thanks to Jordan, our disk server is no longer virtualized. Our long
        nightmare of poor IO performance should hopefully be over. Prepare for
        another long nightmare of poor hardware reliability!

        Just kidding! (I hope)

2/14    You sure soda isn't running windows in disguise?  It would explain the
        uptimes.
        \_ hardly, My winbox stays up longer.
        \_ Nobody cares about uptime anymore brother, that's what web2.0 has
           taught us.  Everything is "stateless".
           \_ You;d think gamers would care more about uptime.

7/22    Playing with dd if=/dev/random of=/dev/<disk> on linux and bsd:
        2 questions, on linux when <disk>==hda it always gives me this off
        by one report i.e. Records out == records in-1 and says there is an
        error. Has anyone else seen this?  Second, when trying to repeat this
        on bsd, <disk>==rwd0 now, to my surprise, using the install disk and
        selecting (S)hell, when I try to dd a 40 gig disk it says "409 records

10/27   I just read an article that Facebook had moved their database
        to all SSD to speed throughput, but now I can't find it. Has
        anyone else seen this? Any experience with doing this? -ausman

8/3     VMWare + Windows XP + Validation question. I need to test stuff with
        Service Pack 3 installed. I have a valid key that I own (yeah yeah I
        actually *bought* a copy, please don't flame me for supporting evil
        M$). Is it possible to register the key once, and then duplicate it
        for testing purposes?  Will Windows or Microsoft detect copies and
        disable the rest the copies?

7/28    Does it make sense to defragment disks on VMWare? My 80GB disk
        on VMWare isn't really using 80GB, it just uses what it needs.
        Will defragment do anything to it?
        \_ If you want to speed up disk operation in your VM, it's best to
           defragment the disks in your VM, then defragment the disk on your
           host machine where the VM files are.

7/24    Firefox 3.5.1 on MacOS is a piece of crap. It crashes ALL THE TIME.
        It has crashed 3 or 4 times on me in the last hour, and not on
        the same pages either. The new Yahoo! home page also sucks ass.
        \_ os x keeps trashing my raid disk: '11 hours to rebuild. have fun
           with the kernel IO subsystem running like shit until then".
           Worthless piece of shit.

        What does the "at sign" mean? This is on Mac OS. VMWare disk file.
        \_ The file has metadata attributes
           \_ How do I add/delete attributes to files? What about
              -rw-r--r--+ <-- what is the "+" sign? Also how do you make
              tar preserve these attributes?
