In 1996 I was introduced to Redhat Linux and my life changed. Over the next few years each position I held involved Linux is some way, but never the main function until LLNL when I became a Linux Systems Administrator. It started as an operator role writing simple scripts and replacing hardware and over time became one of the most enjoyable roles of my career. As I learned more and more, I was given more responsibility. From the largest and fastest computers in the world (top 500), we had 4 in the top 10 at the time, to desktops on the open and secure networks. What I loved the most about this position was that everything was cutting edge and pretty much undocumented. My end users were physicist and viz developers, which meant I was rolling custom kernels and creating my own RPM’s that I pushed out using a local YUM repo.
I was in that position for 6 years before life dictated some major changes and I needed to find a way to work from home. I’d like to return to Linux again someday. For the past 4 months or so I have been playing with Raspberry PI. I built a small 6 node cluster using Raspberry Pi 4′s. I have a couple I use as web servers as well, just to keep my skills sharp.
I have also been thinking about renewing some certifications. The ones I had are long expired. CCNA, RHCE, VCP, etc. I am not sure I really need anything beyond the Redhat certification, it’s probably more nostalgia than anything else.
I <3 Linux!
