12/6    I'm running 64bit VMWare 2.0 in debian lenny/testing.  I have 18
        guest VMs running, all in bridged mode.  Works great.  the 19th VM
        I turn on has no working network.  No net, dhcp/tftp doesn't work,
        nothing.  Can anyone think of a network or kernel setting in Linux
        that would prevent any more VMs from getting network access?
        Is there a limit on number of bridge interfaces?  Where is this
        setting?  - danh
        \_ I don't know, but running 18 VMs on one computer is pretty badass.
           \_ I have DUAL CORE.
           Speaking of which, I want to make a sandboxed network where only one
           of the computers has access to the outside world (since I don't want
           to impact my home network at all). What's the best way to do this?
           --t
           \_ running 18 VMs isn't crazy.  Modern web apps consist of a load
              balancer, a few webservers and dbs thrown in.
              \_ What's the point of running VMs on one real machine and then
                 run a load balancer in the VMs?  Why not just run the web app
                 on the real machine?  There's much less overhead.
                 \_ for testing, not production.
        \_ ask vmw support  There may be a limit there

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:

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)
        In any case, this means that cooler was taken out back and shot, and

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!

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.
