Running Minecraft Server in Kubernetes Cluster
A month ago I had an idea to run a Minecraft server in my garage Kubernetes lab. I though it might interest my little Minecraft player at home with some Kubernetes and GitOps stuff but that failed miserably. But at least I knew how to host a Minecraft server in Kubernetes, with ArgoCD too. First…

My nVidia RTX 3080 ThermalRight Upgrade
Recently I traded my 2x Gigabyte RTX 3070 for a Aorus Masters RTX 3080 for a set of various reasons: For Ethereum crypto mining, a 3080 can achieve ~100MHps, which is very close to what 2x 3070 can do 1x 3080 definitely consumes less power than 2x 3070 If I play games or VR, only…

ArgoCD, Jsonnet and Tanka

A Few Things I’m Grateful about Microsoft Windows
TL;DR. this is my story with Microsoft Windows, from 3.1 to 7. Many years after my mom bought me my first PC, I realized the Windows 3.1 installed by the vendor was a cracked copy, or pirate copy if you will. But Windows 3.1 was really amazing, and I liked it a lot. There were…

First Month With Sanden Heap Pump
TL;DR: This thing is purely awesome! It’s been almost a month since my Sanden heat pump system being installed. The unit is scheduled to start running after 9AM. It probably should start a bit later than that because my solar system can barely produce 900w of power at 9AM in late winter, if it’s sunny…
