Web Site has not been updated for quite a while now but that does not mean that not much has been going on, it just means we have been busy on other things.  We have been having some problems with our IT infrastructure but things are looking up now.  Wiki was up, then has been down for quite a wile now.  We have lost a lot of content, but we are rebuilding that as well.  With luck will have some good news soon.  That is it for this posting, this is my first and just sort of a test.

Everyone loves on-liners, right? No, not those awful puns and jokes your coworkers bother you with, but near-magic on-line commands for the linux / unix command line interface!

I've been "away" for a bit. Even though the school semester has come to na end, I immediately took off for Floriday, for a much needed vacation. My wife and I enjoyed the sun, the surf, and the sights. Then I was back again for a week before I was off again. This time to Virginia to take SANS FOR408 - Windows Forensics.
