Things might be getting somewhat more complex with the COVID-19 pandemic that started in Wuhan, China. The CDC has been posting articles stating that individuals, who have recovered from COVID-19, may be prone to reinfection after three months. The theory of herd immunity, without a vaccine, goes out the door.

The Chinese Communist Party does not seem to accept responsibility for the 800,000 deaths globally which they allowed to happen and are taking advantage of it in different ways.

It is another Saturday in the Twin Cities of Minneapolis and St. Paul. Last night I changed the alarm to wake up at 05:15 AM. That said I was up around 05:00 AM.

One can use different programming languages, frameworks and libraries to develop a RESTful web server which exposes the same API. In this post I will implement a RESTful server using JavaScript, Express, and npm libraries.
I was looking at several articles on binary trees and thought it would be a good opportunity to write some Java code in order to refresh knowledge of binary trees, in particular with BSTs (Binary Search Trees). You never know what new things are out there.
In the past few weeks I have been cleaning and optimizing some operations in a storage server. After running millions of operations I noticed an interesting condition and decided to use a different approach. Did a quick Internet search using Google Chrome for “smart delays” and nothing related seemed to come up. I thought using it for a title for this post would be fine. 
Earlier this week I was talking with a system architect. He mentioned what I consider a sensitive and interesting question. How do you use Dependency Inversion (DI) to test software? If you are interested in this question please
