Hope you are doing well. I fully understand that not all countries are moving quickly to vaccinate most their population against COVID-19. Hopefully the efforts have already started and will be completed soon. Here in the USA it seems that every state is moving at its own pace. That said, a large amount of people have received at least the first of two jabs. The youngest I know of is of age 21. The world needs to get as much of its population vaccinated as possible to achieve herd immunity. If this is not done the virus will continue to mutate and the threat of COVID-19 might remain for years or decades.
It seems that Israel is leading the vaccination process. As in many other countries, there are some people that do not wish to get vaccinated. The prime minister of Israel has made some clever, and for what I understand legal changes to motivate all their citizens and residents to get a COVID-19 vaccine.
In a nutshell the idea is that the good of the majority needs to prevail. People will not be forced to get a vaccine unless there are medical reasons. Besides that, the population needs to show a vaccine passport to work where there is human contact with others. If the person wishes to attend events and places where they could possibly transmit COVID-19, they need to have a COVID test in the previous 48 hours. The COVID tests used to be free but in the near future people will need to pay for a test. So if a person for without a real medical issue does to get the vaccine but wishes to mix and mingle with others, they will have to pay and get a COVID test every other day. I guess Israel will be one of the countries that will reach heard immunity in the very near future. In my humble opinion, we in the USA need to start thinking about each other and work for a common goal. Continue reading “Producer and Consumer”
Things might be getting somewhat more complex with the COVID-19 pandemic that started in Wuhan, China. The 
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. My wife and her friend want to get an early start shopping. They should be back around 11:00 AM. They both took masks, gloves and umbrellas. The forecast does not call for rain in this area, but around the time they were leaving there were some spotty dark clouds.
It is a Saturday in August in the Twin Cities of Minneapolis and St. Paul and it is going to be a warm and humid day. My wife is out shopping with a friend and I am in my home office having fun with Binary Search Trees (BSTs).
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
