Learning Linux Basics

-
I could write several articles on using the Linux command line. However, while reinventing a wheel can be fun sometimes, my best sources that I've used have been the Command Line course on Code Academy, LinuxCommand.org, and the Unix Visual Quickstart Guide. Between those three sources and plenty of practice, you'll get the hang of it pretty quickly.

Practice means breaking stuff and figuring out how to fix it. One of my college instructors once told us that Wisdom comes from Experience and Experience comes from Pain. Breaking stuff can be painful but it's only bad if you don't learn from the experience.

Installing CentOS 7 on a Raspberry Pi 3

-

The Raspberry Pi is awesome. If you're like me, you bought one to tool around with for educational purposes. You can run Kodi or gaming console emulators on it or you can combine some together for a tiny OpenStack cluster. At, $50-$60, they're easy on the wallet and running off of 5v USB power makes them pretty energy efficient. Sure, it's only a 1Ghz ARM processor which limits your OS choices but I'd rather have a Pi than running an old Dell PowerEdge or HP Proliant that I bought off of Craigslist. Instead of installing the usual Raspbian OS, this guide is on installing CentOS 7. However, the process described below is relatively universal to whatever OS you want to install on your Pi.

Modifying the Zebra F-701 & F-402 pens

I've been carrying a pen as part of my (mostly) every-day-carry, or EDC, for a couple years now. I bought the Zebra F-701 and after a few other pen purchases, the 701 is still my favorite of all. At first, I just wanted a pen that looked nice and for the moments I needed to sign something. I recall attending meetings when I worked at the university where the attendees were asked to sign-in on the attendance sheet: I tended to be the only one that didn't have a pen so I felt unprepared when I had to ask one of the other attendees if I could borrow theirs. Once I started college, I found myself using a pen much more often, so it had to be comfortable, relatively inexpensive (nice pens can cost hundreds of dollars), and still stylish enough to live in the pocket of a dress shirt.

How to fix DPM Auto-Protection failures of SQL servers

-
For longer than I care to admit, my DPM server has had the same error every night about an auto-protection failure on one of my SQL servers. I've looked into it before but never came away with anything useful until recently. I've finally found information on how to fix this annoying issue. The Advanced Information link in the error will tell you to make sure WMI is in a good state on the machine. The error itself isn't very descriptive. It'll look something like "DPM could not enumerate SQL Server instances using Windows Management Instrumentation on the protected computer $serverFQDN."
