10/24  What's an easy way to see if say column 3 of a file matches a list of
       expressions in a file? Basically I want to combine "grep -f <file>"
       to store the patterns and awk's $3 ~ /(AAA|BBB|CCC)/ ... I realize
       I can do this with "egrep -f " and use regexp instead of strings, but
       was wondering if there was some magic way to do this.
       \_ UNIX has no magic. Make a shell script to produce the ask or egrep

3/12    I am curious what others think of tablets like iPad. They don't seem
        useful to me, but I use my computer for more than web browsing,
        Facebook, and Twitter. Why would I buy one instead of a laptop?
        They seem like a disabled laptop to me, but at a higher price.
        \_ You are most likely a coder.  iPad is not for coders.  They are
           what you get your non-technical friends.  Or musicians.  Look at

10/14   2 apache 2.0.52 servers running on Linux boxes.  Identical httpd.conf
        files (except for ServerName).  But on one, if a CGI script takes
        longer than 300 seconds, it times out.  The other, not.  Why is that?
        \_ Perhaps network equipment configuration. Or try comparing settings
           in /proc/sys/net.
           \_ I ran /sbin/sysctl -a | grep tcp, all settings are the same.

7/14    Shell Programming question: I want to call a script with 1 arg
        and have it figure out whether $1 is a MAC address or an IP address
        and then do call the appropriate function.  What is the best way
        to do this, given that sh/bash/ksh do not have something like
        the =~ in perl.  Check for exit status of grep, or is there a
        a better way?  For the moment, let's just say the two tests are:

9/4     Happy Labor Day! Thank you, Labor, for weekends, mandatory breaks,

6/12    Inside of a C++ program, I do a "ps | grep usename" for logging
        purposes.  where username = getenv("USER");  Doing this directly is a
        gigantic security hole because someone could set $USER to some command
        line and execute arbitrary code.  What's the best way to make this
        safe?  Is there some standard way to check the input in a case like
        this?

4/12    Just finished a programming quiz. Do you think critizing the test
        was OK? They wanted someone to write code for something that could
        be done via shell aliases. This was at Riverbed.
        \_ I assume Riverbed is a company and this was an interview?  If so,
           I think this kind of criticism is a great thing to do.  It shows you
           really know your stuff if you can do both.  If they count that
