Home Kubernetes cluster
So I admit it - I am completely obsessed with Kubernetes. All of the web app/api deployment challenges in the past 20 years have been somewhat solved with the Kubernetes orchestration and scheduling platform. Kubernetes brings fault-tolerance, and Highly available systems if set up correctly (i.e. use a Kubernetes cloud installer). I enjoy having t…
Why Jesus and Easter Matters
There is a God and He loves you. John 3:16 says, “For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life.”
Everyone is a sinner and our sin separates us from the love that God wants to express toward us “For all have sinned, and come short…
Not posting as much
I have not been posting as much tech stuff on my blog as I want to. The reason for this is I have been mulling about the idea of submitting my tutorials to a publication and get paid for my work. I still have not decided if this is the right course of action. Not that I have to explain myself with the readers of my blog - I just wanted something ot…
Merry Christmas
Merry Christmas from the Wippler family!

The day before thanksgiving, I was pondering an issue I was having. I was pinning a package to a specific version in my Docker container and the repository I grabbed it from stopped offering this specific version.

Settling in
It has been a month and a half since we moved, and we finally are on a set schedule. The girls have started school, all boxes are unpacked, our house in California closed escrow, and we have successfully adjusted to the CST time zone.
It always amazes me how much God has blessed my family. We are all in good health, we are debt free, we have…

Moving Adventures Part 2
(Note: This guest post is from my wife, Nicole. These are the events that happened July 25th, 2017.)
After 6 hours of rest, we awakened rested (somewhat) and ready to resume our journey. Morning was fairly uneventful, and we were back on the road by 9. As we were fueling up, we realized that Clark's cup (which he went to bed with) was accide…
