Last week I started my new job as a Database Administrator (DBA) with Incorporated Research Institutions for Seismology (IRIS). My focus will be working on PostgreSQL databases.



This position is a true Remote job, so I will be working from my home office and hopefully occasionally from other interesting locations.

I assembled the sit-stand desk in my office from an UPLIFT Standing Desk Frame (V2-Commercial) and some used desk surfaces that I picked up from our local salvage yard, The Repurpose Project. This frame is fantastic, remarkably stable (no bounce when typing), and strong enough to support a lot of equipment or heavy surfaces.

I prefer a standing desk. With the COVID-19 work from home orders causing me to become a full-time Remote worker, my home desk area setup is much more important than it was before.

I know some people who stand up at a table or breakfast bar and use their laptops, but that is a terrible neck angle for long periods of time.

If your laptop will open to 180 degrees, then the following configuration with an external keyboard and mouse may help the screen position considerably:



Otherwise, I suggest a laptop stand such as this one from 1home:

which works very well compared to some others I have tried.

Here I am using it in combination with my Ergotron WorkFit sit-stand workstation:

In December I started my new job at Infinite Energy, Inc. as a DevOps Engineer. What attracted me to this job the most was the Culture of the company and the high levels of awareness of the managers that I met.

On my first day I received a laptop and my team suggested that I install Linux.



It is nice to be using Linux again full-time.

We are using GitOps practices with Flux and Kubernetes.

Nothing else much to report yet. I had some time to fiddle with my shell environment. zsh seems to be the popular shell these days so I played with it a little bit but instead decided to stick with Bash. I found a project similar to oh-my-zsh called oh-my-bash which I am using to customize my shell prompt.

Just after Thanksgiving I started my new job as a Senior Site Reliability Engineer for SharpSpring which is located here in Gainesville, Florida.

On my first day they put me at a desk next to the window and I received a nice t-shirt (swag!).



The company just moved to a brand-new office building located in the mixed-use development known as Celebration Pointe.



As a long-time "Linux on the desktop" user, one of my initial challenges has been getting used to MacOS.



I am excited to have plenty of great things to learn. Besides on-the-job training, I am currently working thru a list of Linux Academy training courses. I finished up Docker Deep Dive this past week.

The Advanced Computing and Information Systems Lab where I work recently aquired new hardware to support the storage needs of iDigBio.We operate an open source Ceph cluster to provide object storage for media and datasets. iDigBio was too successful at mobilizing digital media about museum specimens... the original storage cluster is full!

The new hardware is racked and has received the base OS (Ubuntu 18.04 LTS). Ceph makes RAID obsolete, but to get the best utility out of the hardware we needed to flash each LSI controller with "IT" firmware. IT in this context means Initiator Target (also known as passthru). Ceph guides suggest IT/JBOD configuration in the storage controllers to maximize performance and to prevent crappy controller caches from interfering with Ceph's own redundancy.

Our servers from Supermicro include the LSI Logic / Symbios Logic SAS3008 PCI-Express Fusion-MPT SAS-3 adapter. Each host also contains 11 storage drives at 12TB each (plus an SSD for the boot drive), 16 cores of Xeon Sky Lake processor, a whopping 256 GB of RAM, and 10 gig ethernet plugged into the University of Florida Campus Research Network (CRN).

Here are pictures of myself and Nicholas Rejack doing the firmware updates:

The new cluster contains over 900TB raw, getting us close to a Petabyte.

I am now working through SaltStack and systemd configurations, working up to the point where we can actually begin migrating objects from the old cluster to the new cluster.
