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?

I applied and was recently awarded a Cloud-native Application Architecture scholarship by SUSE and Udactity. There were about 12,000 scholars all over the globe who took part in the course made up of 5 lessons in 2 months, with phase 1 ending August 2, 2021.

One of the exercises was to run Docker Desktop on my Windows 10 computer and build a docker image alpine:golang which will run a web application and display the infamous Hello World. I uploaded this docker image to my Docker Hub registry for use in a Kubernetes cluster. 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 k3s by running "curl -sfL | sh"

Next, I pick an ARM image with alpine:golang, but this image did not work and the pods continually restarted. I scoured the internet and found this repo below after trying out over 6 different ARM images


Use the above in your docker file, build it using standard "docker build" command and save the image to your Docker hub registry. From your RPi over an SSH session, run a "kubectl deploy" command to deploy a new golang app using that Docker hub image. I found that the pods stayed up but I didn't get to fully test the "Hello World" golang go-helloworld app via from my host computer. Trying to run it locally on the RPi via is extremely slow and I fear it might be resource constrained.

Here is the day-to-day recap of the scholarship challenge documented here

60 Days of Udacity: A Bertelsmann Technology Scholarship in AI

I applied and was recently awarded the Bertelsmann Technology scholarship where a group of students take part in an Artificial Intelligence track made up of 5 parts to be completed in 3.5 months.    As part of taking the class, we have to take part in a slack channel where we post our daily studies for 60 days reflecting on what we have learned. This is a transcription of those 60 days. The public github wiki is located here  Day 1:  I am in p3  (Datasets) doing the xray annotation project. I have created the appen job using the "Image Categorization" template. I uploaded the xray image data and modified the CML to make the  questions specific to checking for pnemonia. Also updated the Examples section. I am still working out the usage of conditional only-if in checkboxes to determine what other smarts to include when annotators go through the page. Created one Question so far and will continue working on the ot

Unable to get to computer BIOS because monitor goes to sleep at startup?

I just enrolled in a course that requires running virtual machines on my Windows 10 Pro computer using VirtualBox. I couldn't start the virtual machines because of this error "The native API dll was not found (C:\WINDOWS\system32\WinHvPlatform.dll)". After doing some troubleshooting, I found this to mean that the hardware acceleration settings required by the CPU to support virtualization are currently disabled in my computer BIOS. I had to enable virtualization on my CPU chipset (VT-x/AMD-V).  Seems easy enough, right? I rebooted my computer and was expecting to see the memory counter and options to get into the BIOS. It must have been so quick that it took me straight to Windows 10 login prompt right away. I tried again and as usual I am immediately back to Windows 10 login. Each time I reboot, there is a box that says my monitor is going to sleep and does not wake again until presented with Windows 10 login prompt. I can hear the disk and fans spinning during startup,

One of the more underappreciated AWS service

The most under-appreciated AWS service is the AWS Certificate Manager (ACM). This service provides SSL/TLS certificate for your custom domain as long as you subscribe to any ACM-integrated service like Elastic Cache or Cloudfront.  I had been using Wordpress to host my website for some time on a free web hosting provider. In order to provide SSL/TLS web encryption, I would have to buy a public certificate from an SSL provider and have that in front of my Wordpress content management web site. I found there were many limitations with that including installation of a public certificate on a free webhost subscription.  I would have had to start a paid web host subscription and in order to install a paid public certificate on a Wordpress website that wasn't getting a lot of hits. Regardless, it had to be secured via SSL web encryption so this is where AWS Cloudfront came in. Using AWS Cloudfront integrated with ACM, I can get a free public SSL web certificate
