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…

Kubernetes Jobs and Istio
Note: the Job in the title refers to the Job resource in a Kubernetes cluster. At the time the Istio sidecar doesn’t play well with a Job or a Cronjob, because the istio-proxy might not be ready when the Job starts (which causes connection issues for the job) and won’t exit after the job finishes…
