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

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 https://github.com/chromilo/udacity-bertelsmann-scholarship/wiki  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

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 https://aminsolutions.com 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
