4/7     I have very little experience with tape backups.  I have to grab data
        off of tapes that are of unknown format.  Is there an easy way to
        identify what format the data are saved in?  This will be done on a
        linux box.
        \_ dd if=/dev/nstX of=tmp bs=2048k count=1
           file tmp (or whatever you call the file)
           This will recognize at least tar and dump formats not sure
           about networker/netbackup/other comercial apps.
           \_ Awesome.  Thanks.
           \_ that won't "recognize" anything at all; it will copy the
              raw data off the tape, transferring the problem from "what format
              is this tape in?" to "what format is this file in?"
              \_ % file tmp

2/19    I program a lot by sshing to a Linux cluster.  So I'm used to using
        Xemacs to code.  This works fine from a Linux or Windows workstation,
        but sometimes I have to use a Mac.  On Mac, the meta is usually
        bound to option, but that often doesn't work over ssh for some reason.
        This makes using emacs a real pain.  Any suggestions on how to fix it?

8/26    Amazon medium instances (3.75GB RAM): 0.160/hour = $1382/year
        Generic standard Linux VPS (4GB RAM): $480/year
        Amazon costs more (but does offer superior scaling options).
        \_ Amazon is $670 if you buy a year's usage up front (heavy util).
           Why is heavy util less expensive than light util?

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:

7/21    Can I just use ifconfig to expand my netmask on a FreeBSD box?
        Are there any gotchas here? Linux forces me to restart my network
        to expand my netmask.
        \_ yes... and no, you don't have to restart your network on linux either
           \_ Rebooting is the Ubootntoo way!
              \_ Oooboot'n'tootin!

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

5/26    anyone use lxde?  supposedly it is less stupid than xfce and
        less bloated than gnome.  thoughts?
        \_ lol, does anyone still use desktop linux?  Get with the times
           buy a mac.  Now.  DO IT.  Go NOW.

5/5     Does anyone know how to do custom install of Ubuntu 10.04? I can't
        even boot it up to give me the menu to custom install and it
        keeps installing a bunch of crap I don't need. It's getting
        just as slow and bloated as Winblows install. Dear lord,
        I miss the old Ubuntu.

4/22    In Linux is there an easy way to rename the scripts in /etc/rc?.d ?
        For example I want to set all the /etc/rc?.d/S91apache to S100apache
        so that it'll run the ramdisk BEFORE going to apache.
        \_ Sure, just move them.
           \_ I mean is there a script that will rename all of them
              for me? Like: setrc apache2 0 0 1 1 1 1
