4 Things You Must do When Taking a Proctored Exam

This was my proctored-exam transcript last night when I took the AWS Solutions Architect exam (SAA-C02) as part of my recertification because it expires every 3 years. This was a remote proctored exam through PSI and should have been easy because this wasn’t the first time I used their service. For whatever reason, last night’s experience was so bad  that an exam that started at 10:45pm didn’t finish until early morning 2:15am.  Some things that you could do to avoid what I went through: 1) Test your computer 24 hours before start time This was my fault and I should  tested sooner. I did start preparing foe the prerequisites as early as 8pm and thought I had enough time to complete everything as it was the same computer I used three years ago when I got certified with AWS. However, I found that since the last time I took this exam, my hardware changed (different web cam, different speakers) and I installed more software like Docker that the proctoring software (PSI Secure Browser) didn

What Docker Image for GO works on a Raspberry Pi 3 running Kubernetes k3s orchestrator?

We needed to install Oracle VirtualBox, Hashicorp Vagrant, and run Kubernetes k3s cluster to host this docker image. This worked well on my computer but I wanted to try the same exercise on my RPi which had a lot less resources and wanted to see how well it worked there. I have a Raspberry Pi 3 running Raspian OS with 32GB of disk and 4GB of memory. I connected the RPi via wifi on my local LAN and have opened up an SSH session to it. First I install
