12/20   My iPod<->PC rate is about 2megs/second. That is a lot less than the
        400mbps/second for a typical firewire. Is there a reason why?
        \_ Possibly inefficient implementation of PCI.
        \_ you're writing to a disk

12/20   If one is snarfing porn and one has used a secure erasing program
        to erase the incriminating files from one's own drive. How many
        other locations likely have records of the transaction and how long
        will those records persist? This was via kazaalite, a spyware-free
        p2p client.
            \- just out of curiousity, is this a shared work computer, hide
               from spouse or is it child p0rn or something like that? --psb
        \_ The server, in its log files, forever. Your browser cache,
           until you clear it. Your browser history file, for however
           long you have your browser set to retain files.
                \_ You forgot about the logs for all of the transparent
                   proxies (most of them will have copies of the content
                   in their caches as well).
           \_ The server as in the server from whence I downloaded the porn?
              A bummer about Windows Media Player is that I have know idea how
              to clear its buffer. Anyway, thanks. This is pretty much as I
              figured. I was worried about things like whether our router or
              our DSL modem keeps transaction logs.
              \_ has a howto for being able to clear WMP's
              \_ It depends on the router.  Some routers have the ability to
                 replicate all packets coming in from a certain port or IP
                 address and redirect it to a workstation with analysis
                 software running.  This is standard practice in the heavily
                 loaded POPs.  ISPs analyze traffic patterns to better plan out
                 network buildouts.

12/20   Perl question:
        # Doesn't work
        my @list = (1, 2, 3);
        my $name = "list";

        # Works
        @list2 = (4, 5, 6);
        $name2 = "list2";
        \_ Short answer: replace the second line with  my $name = \@list;

           Long answer: using a string like "list" to access the variable
           @list is called a symbolic reference.  It works, but there are
           some restrictions -- for example, if the variable @list gets
           garbage-collected, your reference won't work anymore; also, as
           you noticed, it only works with global variables.

           If you use \@list instead of "list", then you get a real (non-
           symbolic) reference, which you can use exactly the same way but
           doesn't have the problems above.  See "man perlref" for details.
           \_ thx for the explanation.  I'm not sure my $name =\@list
              is what I want, because I may want to pass "$name" as a command
              line argument to choose between different lists.  Actually,
              someone may want to do that, not me.  I was just helping.

12/21   does anyone know the name or singer of the song that was in
        the movie Home Alone? it was a variation jingle bells I'm
        pretty sure.
        \_ Jingle Bell Rock? Google says Bobby Helms sung it.
