On occasion I have talked about military force multipliers. These are things like terrain and minefields that can make your force able to do their job much more effectively if utilized correctly. In fact, a study of military history is every bit as much a study of battlefields as it is...
It is an interesting twist in the IT world that with the increased usage of purchased packages and the growth of on-demand IT, we increasingly find ourselves talking about “Applications”. This is a good reference point, it addresses all of the things running on our servers with one fel...
Rubik’s Cube was first patented in 1974. The first book talking about a solution algorithm was published in 1981. In 2007, computers were used to deduce the smallest number of moves to solve a cube, and in  2008 that number was further reduced. That’s 34 years after it was invented. An...
Lori, the Toddler, and I drove down to my mothers’ house in Cincinnati (about 9 hours away) for the fourth of July weekend. Our youngest daughter drove her car with her sister, the sister’s fiancé, and our grand-daughter. We stayed in touch via text message and drove through the night....
So I’m jealous that Lori works D&D references into her posts regularly and I never have… Until today! For those who aren’t gamers or literary buffs, a Hydra is a big serpent or lizard with a variable number of heads (normally five to nine in both literature and gaming). They’re very p...

THE LITTLE GYM AND TODDLER HERD-THINK Lori and I take the Toddler to the Little Gym, a place for toddlers to go hang out with other toddlers and do some semi-directed activities designed to build confidence and muscle. We think it’s really very good for him, and he  attends with h...
There are two interesting and complimentary rules in IT: 1. When a technology takes off, vendors will keep trying to find “the next big thing” to earn more of your business; 2. Until something takes off, most IT staff doesn’t have time to worry about it. Virtualization is one of those...
And yet we never see them when we’re not interacting with them. Unless we bought really cheap ones or have gone literally years without maintaining them or put them together wrong when we first got them, we never fear that they will fall apart randomly on us, and we never fear that the...
“Web Server XYZ is out of disk space” says the voice on the other end of the line in a tone that, at 2am, could pass for Scotty screaming “Capt’n! I don’t know how much longer I can ‘old her together!” And that’s just the beginning of your nightmare, for this is exactly the scenario t...
George Crump over at Storage Switzerland has a pretty good introductory primer to File/NAS Virtualization. George and I haven’t always seen eye-to-eye, but that’s no surprise, I’m one of those people that wants analysts to prove they’re working on solid ground, and he’s an analyst. Bot...
