Five years of

Today marks the fifth year that this blog has existed on the internet. I bought the domain on February 14th, 2007 and tossed together a quick WordPress installation (I can’t even remember the version now!) to hold my notes that I was gathering at work. Rackspace as an entry-level Linux system administrator. The abrupt change from “top dog at the startup” to “wow, I don’t know anything about Linux” caught me by surprise and I was trying to stuff as much knowledge into my brain as quickly as I could....

You might see me on CNN Money soon

Hosting the politicians

Call me weird - but I like to know where people host their sites. When I get a link to a nice-looking site, I’ll get there and think, “Hmm, I wonder where they host.” Part of this curiosity probably stems from being a server administrator. I’ve used seven different dedicated server providers before along with 5 different VPS providers. There’s quite a few shared hosters thrown into the mix as well....
