OMG a blog update!

It’s been a while! I’ve been super busy with work. A quick update ::

• I’ve been studying for the first of my RHCA exams. Hopefully I’ll be able to start taking these soon.
• I have had 2 different positions at work in the last 6 months. I was part of our Professional Services team where I was building custom configurations for customers, and then I moved on to a more undefined role. I can’t talk a lot about the new role at this time, but I can say that it is technical with some Business Analysis thrown in for good measure.
• My grandfather passed away. It’s been rough.
• I quit using twitter – I’m 100% on facebook now

That’s mostly it. I know it’s a short post, but I’ll update this blog soon. I’ve got a lot of builds and configurations I’ve done, and I’ve written a few technical posts that I need to edit and post. Until next time!
