Journal Punk Walrus's Journal: Should I start a journal here?

I am debating on whether or not to have a journal here. At first, I thought, "Why?" but then I realized that my own journal on my web page is always trying to decide whether to cater to techy or journal people.

If I use this site, I think I'll do all tech-related notes.

Here's a taste: I just took the RHCE 300 Rapid Track course, and while I didn't pass the exam, I learned a LOT of cool stuff. One of them was a script our teacher made where you can see who has ssh access on your dhcp leases:

# Copyright 2003 Brad Smith

for i in $(perl -ne 'm/^lease\D+?(\d+\.\d+\.\d+\.\d+)/ ;
if ($1 != "") { print "$1\n";}' /var/lib/dhcp/dhcpd.leases) ;
do echo "Who's on $i?" ;
if ping -c1 -W1 $i &>/dev/null ;
then ssh $i w ;
else echo "Nobody there!";
fi ;

Arg... this journal format doesn't lend to cut and pasting code very well...
