On a new install of Docker, it sets the data folder path to /var/lib/docker. That's good for most use cases however I had to setup docker on a server with an external NFS mounted storage. After trying out a few of the older methods which were too cumbersome or didn't work, I stumbled on a newer approach that suited my needs. Below are the instructions I used to get it to work.

I got curious about the Raspberry Pi serial connection recently so went about getting it to work on mine. It's mostly for fun but I can see the benefit when I want to find out the IP address of my Pi without having a monitor and keyboard on hand. Plus, I this would benefit the classes I plan on running as I may not have extra monitor and keyboard for the classes.

I managed to find my I2C OLED display when I was cleaning up my place. As I currently have a S3 storage cluster project ongoing, I figured now would be a great time to get it working so I can attach an OLED display to each of the Raspberry Pis so I can get their status on a glance.

I recently purchased an RPG called The Operators that lets you play as Ethan Hunt or Jason Bourne in a techno-spythriller.

The author, Kyle Simons is best known for his previous game, Worlds in Peril for bringing the comic book world to life that was based on the Apocalypse World system.

Recover Archlinux Kernel

My recent kernel upgrade for my ArchLinux server failed because my /tmp folder was full and the package manager couldn't use the /tmp folder to build the necessary modules and tools. Despite knowing this, I decided to reboot the server anyway and that's when I saw the dreaded kernel panic message making my server completely unusable. However, I knew my data was still safe on the server, it just couldn't boot up so I did what any geek would do, I decided to fix it.
