11/29   I archived a big direcotry (3GB) using tar with bzip2 compression (-j)
        and I notice that to extract any file, tar seems to read through
        the whole archive decompressing it byte by byte and takes a VERY long
        time, no matter how small that file is.  Is there a better archive
        method?  (I am archiving on to a file, so dump does not work.)
        \_ Use zip.  The compression isn't as good, but you can access any
           file instantly.
           \_ I need good compression but I won't add files to the archive,
              so a tool that puts all the directory information at one place,
              compress the files individually and allow random access is what
              I am looking for.  (And it has to be available for Macs too.)
                \_ Why don't you just run bzip2 on foreach i ( * )?  -John
        \_ Perhaps RAR, Not free, though.
        \_ 3GB is not that much. Burn it on a DVD.

9/19    "No, A Severed Finger Will Not Be Able to Access a Stolen iPhone 5S"
        I'm sure the Apple QA department has tested extensively that a severed
        finger will not be able to access a stolen iPhone 5S.
        \_ It doesn't matter whether or not a severed finger can be used.  It
           matters whether or not a robber thinks that a severed finger can be

6/6     Wow, NSA rocks. Who would have thought they had access to major
        data exchangers? I have much more respect for government workers,
        crypto experts, mathematicans now than ever.

8/29    There was once a CSUA web page which runs an SSH client for logging
        on to soda.  Does that page still exist?  Can someone remind me of the
        URL please?  Thx.
        \_ what do you mean? instruction on how to ssh into soda?
           \_ No I think he means the ssh applet, which, iirc, was an applet
              that implemented an ssh v1 client.  I think this page went away

8/6     Amazon and Apple have lame security policies:
        "First you call Amazon and tell them you are the account holder, and
         want to add a credit card number to the account. All you need is the
         name on the account, an associated e-mail address, and the billing
         address. "

5/8     Hello everyone!  This is Josh Hawn, CSUA Tech VP for Spring 2012.
        About 2 weeks ago, someone brought to my attention that our script
        to periodically merge /etc/motd.public into /etc/motd wasn't
        running.  When I looked into it, the cron daemon was running, but
        there hadn't been any root activity in the log since April 7th.  I
        looked into it for a while, but got lost in other things I was

11/16   We'll be taking all CSUA machines offline in the near future for a Soda
        Hall server room reorganization (we're being moved to a neighboring
        server cabinet).  Downtime will hopefully be minimal.  --jordan
        \_ Thanks for all your work keeping the machines running!  It's
           been awesome having soda actually working again.
        \_ Update:  this is tentatively scheduled for Saturday afternoon.

8/9     So I just found out that an old college friend of mine lost her
        four month old daughter to SIDS. What is the correct response here?
        \_ "Did she sleep with her belly?" and "Did you breastfeed?"
        \_ try this joke:
           How do you make a dead baby float?

5/3     Is it possible to bzip2 on the fly? Like:
        % dump_stuff | bzip2 -stdin > dump_file.bz2
        \_ Yup, it works fine.  You don't even need a flag:
           % dump_stuff | bzip2 > dump_file.bz2
           \_ whoa, why didn't anyone tell me about this, and why is this
              not on the man page. I've been doing the stupid command

9/23    I need to make an image of a disk a disk on a different machine
        in Linux. That is, Make an image of A's disk, on B, and then
        later be able to just copy the image back on to A.
        ADDENDUM: It would be nice to be able to compress the image on the
        way out.  Tar and gzip or bzip2 I suppose.
        \_ Is this a question or an observation? I need a big-breasted

4/22    So is the defactor compression program on UNIX bzip2 now? I gotta
        admit it compresses a lot better than gzip, and while it's hecka
        slow it's pretty good.
        \_ No, it's still gzip. bzip2 is only for dweebies who care about
           saving 10-20% on a file in return for 50% more compression/
           decompression time. If your internet pipe is really limited I
